5 and 6 a box member 70 surrounds and is welded to the transverse rod 64. FIG. Also, the harvested path is limited to the width of the picking head, typically 3 to 4 feet. They are followed by abundant, juicy and edible blue berries in summer - a delight for birds, wildlife and humans alike! The kinematics parameters include the angular speed of the picking reel, the machine velocity and the kinematics number. 14 and 15. The number of tines, whether with the first or the second embodiment, is a substantial reduction from the number of tines of the Prior art. Centrally of each frame member 254 there is provided a stub member 258 to which is connected one end of a two-way hydraulic cylinder 260, the rod 262 of which is connected to a corresponding stub member 264 affixed to the front and rear frame members of the upper frame portion 224. FIG. Extending rearwardly from the forwardmost member 216 of the frame portion 214 is a pair of tongue members 218, each being pivotally connected to the frame member 216 in a conventional manner. At one end of the box member 70 is a roller member 72 mounted within lugs 74. They aren't very often cultivated specifically for their berries on a large scale. FIG. 14 in various positions depending on the operation thereof. Another pulley 304 is mounted to a bracket 306 on the side of the tube 292 opposite and in line with the pulleys 300. The harvester of claim 12 wherein said tines are formed from spring steel and are mounted in spaced relation to an elongated box member secured to each rod, each said box member carrying a rod member opposite the tines for retention of berries stripped from berry plants by said tines. The frame member 38 performs the same function as the arm member 52 and for the purposes of this discussion may be considered as being an arm member. The harvester of claim 1 wherein said counterbalance means includes, for each of said picking heads: a tension member attached at one end to the picking head and extending towards the tractor over a plurality of pulley members to counterweight means attached to the other end thereof; said counterweight means being movable vertically between upper and lower limits; and an adjustable hydraulic cylinder member engaging said tension member between a pair of said pulley members for adjusting said counterbalance means and for elevating or lowering the picking head as desired. values of lowbush blueberry characteristics are used in kinematics synthesis of the harvester: blueberry stalk height 350 mm, rhizome stalk number 6, length 130 mm and diameter of a blueberry 7.5 mm. 12. This has the effect of altering, albeit slightly, the pitch angle for each tine due to the pivoting nature of the height adjustment. The rhizomes don't like to be dislodged during those early years. Instead, it's much more commonly their larger relative, the Highbush Blueberry (Vaccinium corymbosum), that is found on supermarket shelves. FIG. Lowbush Blueberries (Vaccinium angustifolium) are low-growing wild shrubs native to North America. In this project both mechanical walk behind and manual equipment will be By using The Spruce, you accept our, How to Grow and Care for Black Huckleberries. ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNORS:COLLINS, GEORGE E.;COLLINS, JOHN E.;COLLINS, MICHAEL G.;REEL/FRAME:006750/0780, Free format text: When tile counterweights are resting at the lower limit 90, with the tension member 76 fully relaxed, the full weight of the picking head will be acting on the ground through a rear mounted support roller (not shown) and through any wheels helping to support the head. High brush blueberry patches are planted by individual harvesters and are commonly harvested with heavy duty blueberry rakes as there are typically more berries. 13, wherein a single tine is followed as it moves with the reel 222. This prepares the tines for a generally vertical entrance into the plants to be harvested. The typical manner of blueberry picking has involved the use of a hand tool wielded by an individual picker, the tool being like a combination comb and scoop, which is moved through the berries to scrape them from the bushes and collect them in a funnel-like portion of the tool. In the Bragg harvester, as the tines approach top dead centre of the reel they are caused to flap rapidly to dislodge the berries carried thereby for easy deposit on the internal conveyor. The circular form of the cam continues to almost 1 o'clock and as the tines pass through the vertical they start to dump berries into the central part of the reel so that they fall towards the conveyor 98. By mounting the blower at the discharge end of the angled portion of the conveyor 98 there is very little debris in the berries as they are collected in flats at the end of the conveyor 114. The brush 66 rotates in a direction opposite to that of the reel 60 so that the brush and tines are moving in the same direction at their zone of contact at the top of the reel. For example, an early harvester is shown in Canadian Patent No. However, the Present reel exhibits distinct differences in the manner in which the harvesting tines are controlled. After the point Z the cam flattens somewhat to turn the tines more towards the vertical so that they Will contact and enter the rotating brush for cleaning and debris removal. During the summer the small, sweet, edible berries begin to ripen. The picking heads 18 are substantially identical, the only difference being in the direction in which the harvested berries exit the picking head. There have been many attempts in the past to devise a mechanical harvester for the picking of lowbush blueberries, particularly in the maritime provinces of Canada where there are extensive fields of the crop to be picked each year. FIGS. FIGS. The present invention relates to a berry harvester in general and, in particular, to a harvester for lowbush berries such as strawberries or wild blueberries. Some varieties can grow in zone 2 or in zone 7. That way, at least you will still get a berry harvest annually. The counterbalance means 26 will now be described, with particular reference to FIGS. The arrangement ostensibly accommodates variations in the ground by allowing for pitch and roll of the head during operation. The manner in which the reel 60 is mounted in the frame 58 and the drive therefor will not be specifically described herein as there is no substantial difference between the present arrangement and that of the prior art. The counterbalance system described above alleviates the effect of the picking head 'weight in that by suitably operating the adjustable tension member 92 the operator can relieve the weight of the picking head by up to about 75%. FIG. 11. The harvester 200 is again adapted to be pushed by a tractor 202 operating in reverse, as in the first embodiment, the direction of travel being shown by the arrow "T". Lowbush blueberry, Vaccinium angustifolium (Aiton), is a perennial shrub native to northeastern North America (Vander Kloet 1978).In Maine, lowbush blueberry is managed for berry production with >60,000 acres in production (Yarborough 1998).The crop is not planted. It's possible to propagate Lowbush Blueberry from half-ripe wood cuttings, but it's a slow process, and it isn't always successful. 12 is an end view of the cam arrangement for the tines of the second embodiment. The conveyor 114 is similar to the conveyor 98, having a wide, sectioned belt 116 with flights 100 thereon about every 2 inches. When the tine arrangement is mounted on the reel each roller member 72 will contact the cam 68 and act as a cam follower with respect thereto. A vertical rectangular frame 46 is provided at the rear of the truss section and is connected to the tractor's three-point hitch 22 by connecting members 48, 50 in a conventional manner. How to use lowbush in a sentence. 13. Using a thin layer of organic mulch to cover the ground around young shrubs can help to protect the roots and rhizomes. At the point Y the cam takes on a circular configuration, which causes the tines to take initially a generally horizontal orientation as they pass through the plants and strip the berries therefrom, the berries resting on tile tines and being pushed towards the bar 71. This makes it easier for the tines to enter the berry plants without disturbing the plants themselves as the reel rotates and means that the tines will have a better chance of stripping all of the harvestable berries from the plants. They like sandy, well-drained, acidic varieties, and, ideally, it should be organically rich. With reference to FIG. The tractor operator will have appropriate controls to ensure that he can control the operation of each component on an individual basis in order to ensure safe and efficient harvesting of the berry crop. By using a plurality of counterweights the operator has less weight to handle in the event that he has to remove and/or replace individual counterweights. 7. This plant has no children Legal Status. FIG. 10 and 11 are end and front views respectively of the picking head of FIG. At the upper end thereof and below the discharge portion 106 is a plastic or sheet metal pan 108 which spreads and redirects the berries, as well as debris such as leaves, stems, et cetera, backwards and downwards towards the reel 60. With the second embodiment of the invention the entire reel and its mounting frame is raised or lowered by the same amount at the front and at the rear thereof so that there is no change in tile pitch angle of a tine during height adjustment. This has the effect of again progressively opening the tines 62 outwardly so that as they approach the ground they are almost pointing vertically downwardly. Owner name: The brush 272 will engage the tines 62 as they are directed thereinto by the cam track 270 and will force from the tine berries that have become lodged in the tines and debris, such as leaves or stems that were caught by the tines during harvesting. FIG. All components of the harvester of this invention are operated hydraulically in a conventional manner. 16A through 16F, it being noted that the tension member 280 passes over the pulleys 300 then into the tube 292 and around the pulley 298, then upwards again to pass over the pulley 304, and then downwards for connection to the counterweights 310. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. 1. At the outer end of the reel the conveyor 98 angles upwardly and laterally as at 104. These changes will be discussed with reference to FIGS. Late lowbush blueberry, Vaccinium angustifolium Go to results page Mountain cranberry, Vaccinium vitis-idaea Go to results page Northern blueberry, Vaccinium boreale 961,275 of The Chisholm-Ryder Company. 1 and 2 and the "front " of the tractor and the harvester will be at the right hand end of those figures. Thus the reels, conveyors, blowers and counterbalance systems are powered by the tractor'hydraulic system or by an independent system connected to the tractor'power take-off. Because this shrub produces long underground stems called rhizomes, in well-established plants, propagation from these can produce good results. These are the berry bushes that provide the blueberries that we often see at the local supermarket. Here at home there are a few patches of lowbush native to the eastern US right outside my door, the hillside blueberry (V. pallidum) with thin, woody stems and smooth, unserrated leaves. This is a distinct advantage over the prior art harvesters, both from the standpoint of reducing damage to the berry bushes and of reducing damage to the picking head and improving the ease of turning the harvester when necessary. Providing your Lowbush Blueberry is planted in a site that has the right conditions, they're regarded as pretty low maintenance. Any debris that reaches that stage is easily extracted by the operator riding on the platform 24. After the point B at the upper rear thereof the cam track 270 deviates from its circular path, extending inwardly in stages towards the point C, almost in a direction tangential to the circular reel 222. 3. Mechanical harvesters date back to the late 1960's, having been developed by individual berry farmers or by companies that see the business as a profitable one. 8 is a partial plan view of the harvester of FIG. The lowbush blueberry is native to Canada, Maine, and Massachusetts and also grown commercially there, mainly harvested from managed wild patches. The counterweight member 290 includes a hollow tube 292 having an hydraulic cylinder 294 mounted therein, with the bottom of the cylinder adjacent the bottom of the tube. Lowbush blueberry cultivation on harvested peat fields is of recent interest and data about the pH demands of lowbush blueberry plants on these conditions are still insufficient, although some experiments have been made in this respect (Noormets et al., 2002). The harvester 10 involves a pair of picking heads 18 mounted within and carded by a truss section 20. They can do well in sunny regions, and are also fairly hardy. 16E and 16F the counterweights 310 will be elevated to contact the limit stops 308, at which point no further elevation thereof is possible. Most of the debris will be flung from the brush away from the reel 222 and its internal conveyor, while most of the heavier berries will drop into the internal conveyor. A harvester for lowbush berries comprising: (a) a plurality of independent picking heads offset longitudinally and laterally relative to a direction of travel, each picking head including frame means, a line-carrying harvester reel rotatably mounted in the frame means, and means supporting the frame means above the ground; (b) a truss section to which said picking heads are mounted, said truss section being pivotally connectable to a tractor; (c) tongue means pivotally connected to a forward portion of said truss section and connected to a respective trailing picking head; (d) first conveyor means extending laterally from within each of said harvester reels to remove from the reel berries deposited therein; (e) second conveyor means extending rearwardly from each first conveyor means to respective berry collection stations mounted on the tractor; and. Fruit d’Or provides a clean, field-to-table, low-bush whole fruit wild blueberry powder as Blue Naturelle Organic Wild Blueberry Powder and Blue d’Or Conventional Wild Blueberry Powder. The revised picking head is the subject of a copending, commonly assigned, concurrently filed patent application. Key words: agricultural engineering, blueberry harvester, picking reel, constructive and kinematics parameters. The harvester of claim 9 wherein said second conveyor means receives berries from said deflector shield and transports them rearwardly and upwardly for reception in container means Positioned below the free upper end thereof at the berry collection station. Learn tips for creating your most beautiful (and bountiful) garden ever. They like sandy, well-drained, acidic varieties, and, ideally, it should be organically rich. No. In fact, the first pass of the harvester through a field will result in some loss due to crushing by the tractor wheels, unless a path is cleared first of all by manual harvesting. Highbush blueberries should be planted 6 feet apart. A number of different machine harvesters are available. As mentioned above, this pulls the tension member or cable 76 downwardly between the rearward compression supports 82 and raises both the counterweights 84 and the picking head. As with the first embodiment, there is a Plurality of tines 62 spaced apart along and mounted to a rod 64 that spans the width of the reel 222. It is native to the colder regions of the country, like New England. Between these positions as seen in FIG. The upper frame portion 224 is rectangular in outline, with side members 228, front member 230 and rear member 232 welded together as in FIG. A truss section is mounted to the three-point hitch of a tractor adapted to run in reverse, the truss section pulling a pair of laterally and longitudinally offset picking heads contained within the periphery of the truss section. The low stature of the plant, uneven terrain of the fields, and competition from other weed species present formidable obstacles. FIG. Generally speaking, therefore, the present invention may be considered as providing a harvester for lowbush berries comprising: (a) a pair of independent picking heads offset longitudinally and laterally relative to a direction of travel, each picking head including frame means, a line-carrying harvester reel rotatably mounted in the frame means, and means supporting the frame means above the ground; (b) a truss section to which the picking heads are mounted, the truss section being pivotally connectable to the three-point hitch of a tractor; (c) tongue means pivotally connected to a forward portion of the truss section and connected to a respective trailing picking head; (d) first conveyor means extending laterally from within each of the harvester reels to remove from the reel berries deposited therein; (e) second conveyor means extending rearwardly from each first conveyor means to respective berry collection stations mounted on the tractor; and (0 counterbalance means mounted on the tractor for automatically reducing the weight of the pie-king heads acting on the ground and for elevating the picking heads as desired. Because this shrub doesn't like root disturbance, especially as it's growing, it's best to sow the seeds in pots. The truss section 20, in turn, is connected to the three-point hitch 22 of the tractor so that the truss section is pushed by the tractor as it proceeds in the direction of travel.
