摘要： An improved tomato harvester separator of the type having lengthwise extending bars with lengthwise extending gaps between them, has series of slender resilient fingers extending in both directions from alternate ones of the bars. This placement of the fingers, with alternating fingerless bars adjacent to the rows of fingers, avoids the progression of the tomato plants and their tomatoes to one side of the separator during shaking and separation, and therefore is particularly useful in harvesters wherein the stream of separated tomatoes is divided to two sides of the machine.

摘要： A single-row tomato harvester. A tractor fully supported on its own wheels, has its wheels being spaced apart sufficiently to bridge a previously harvested bed and ride in its furrows. The tractor has its own hydraulic pump, a power take-off unit along the tractor's longitudinal centerline, and a rigid draw bar at its rear. A harvester assembly having no motive power is partially supported on wheels spaced apart widthwise at substantially the same distance as those of the tractor and has a series of hydraulically powered means. The harvester is offset by one bed from the tractor during harvesting. A tongue pivotally attached at one end to the harvester and the other end to said tractor, supports a hydraulic pump for operating the harvester's series of powered means. A longitudinally rigid drive line, swivel mounted to said pump's rotary shaft and to the tractor's power take-off unit, has telescoping means for automatically lengthening and shortening it. The drive line lies along the centerline of the tractor during the offset harvesting. A hydraulically powered generally horizontal cylinder-piston apparatus is pivotally attached at one end to said tongue and at the other end to the harvester for shifting the relative lateral position of the harvester assembly to the tractor.

摘要： A tomato harvester of the type having a main frame and acting to sever the tomato plants below ground and to pick up and elevate them to a tomato separator for separating the tomatoes from the vines. A low elevator segment is separated from an upper elevator segment to provide a gap between them through which dirt clods and some loose tomatoes can fall. The length of the gap is adjustable by moving the upper segment relative to the lower one. The separator includes a walking bar type of shaker with vine retarding tines above the walking bars, and the tines are rotatable and ganged for movement up and down, to adjust dwell time in the separator. The crankshaft for the walking bars has crank pins alternating at 180.degree. and has at each end a pair of timing journals extending at 90.degree. to the crank pins to which the walking bars are secured. The outside journals are located 180.degree. out of phase with the two journals mounted inwardly thereof, to provide two force couples in balance. Balance is completed by a counterweight secured to the crankshaft at each end to provide a force couple equal to and opposite from the force couple resulting from the crank pins.

摘要： A tomato harvester having a standard tractor pulling a non-self powered harvester assembly partially supported on wheels and partially supported by the tractor. The harvester assembly has a main frame made up of two parallel longitudinal beams joined together by three transverse cross members, all lying approximately on the same horizontal plane. Brackets secured to the beams and extending down below them support a pair of two-wheel truck assemblies, the wheels lying below the frame. The frame carries a pivotally attached pickup unit, with a cutter, a separator unit for separating the tomatoes from the plants, and a conveyor system for transporting the collected tomatoes and delivering them to bin-trailers. A tongue comprises the sole structural member tying together the harvester assembly and the tractor, and carries hydraulic conduits leading from said tractor power-take-off unit to operate the powered devices of the harvester assembly, including apparatus for automatically keeping the cutter at a constant depth below ground. The harvester carries a hydraulic fluid storage tank and a hydraulic fluid cooling device.

摘要： A tomato harvester pickup and harvesting method. A pickup conveyor with a relatively flat pickup angle is combined with an overhead assist system. An assist frame pivotally secured to the pickup frame above and spaced from the forward end of the conveyor pivotally supports, with spring return, the front end of a plurality of generally horizontal guideways forward of and above the forward end of the pickup conveyor. The rear end of each guideway is steeply upwardly and rearwardly inclined but forward of the pickup conveyor. A corresponding plurality of powered endless overhead assist chains are supported by the front and rear ends of the assist frame and the guideways for movement in a path extending horizontally rearwardly along the guideways, then up steeply with increasing spacing from the pickup conveyor to the rear end, and then downwardly and forwardly to the front end. From each chain a series of flexible projections extend out substantially normally. When the assist chain moves along its guideway, some projections extend down into tomato vines and engage them, and then they carry the vines upwardly steeply along the steeply inclined portion of the loop. A series of vine releasing tines extend downwardly and then rearwardly and act to free the cut vines from the assist chains when the vines lie over the pickup conveyor, thereby insuring transfer of the vines fully to the pickup conveyor.

摘要： Tomatoes are mechanically harvested by moving a mechanical harvester through a row of growing tomato plants, severing the plants below ground, and picking up the severed plants along with loose tomatoes and some dirt clods, while returning loose dirt to the ground. The severed tomato plants are separated from the loose tomatoes and dirt clods and are shaken to remove the tomatoes from the plants. These tomatoes are recovered and conveyed forwardly past sorters. In the meantime the originally loose tomatoes and clods are passed rearwardly countercurrently to the mainstream of tomatoes, by the sorters for recovery of good loose tomatoes. Preferably, the pickup is made at about 15% slower than the ground speed of the harvester, while the separation between plants and the clods and loose tomatoes is made at the ground speed and the separated plants are carried away from that separation step at a speed about 15% greater than the ground speed of the harvester.

摘要： A known and commercially available electronic sorter is positioned between the sorting conveyor of a tomato harvester and the front cross-conveyor thereof. This sorter includes a rejector mechanism for rejecting tomatoes of colors other than those corresponding to red-ripeness. A rejection chute receives culls impelled thereinto by the rejector mechanism dropping the rejected fruit on the ground, while accepted fruit falls to a front cross-conveyor. A preparatory mechanism associated with the sorting conveyor impels the tomatoes at a desired trajectory toward the electronic sorter, and preferably includes an elevating flighted conveyor for receiving tomatoes from the sorting conveyor, raising them to a higher level, and then dropping them forwardly on to an intermediate generally level conveyor. The intermediate conveyor is driven at a constant speed regardless of the speeds of all other moving parts of said harvester. A dampening mechanism engages the tomatoes on the intermediate conveyor and brings them to relative rest thereon, so that there is substantially no relative movement between the tomatoes and the intermediate conveyor as they approach the forward end thereof, so that the forward end of said intermediate conveyor thereby impels all tomatoes thereon at the desired trajectory toward the electronic sorter.

摘要： An improved tomato harvester severs tomato plants just below the ground and picks up the plants. Dirt clods, along with some loose tomatoes, are mechanically separated from the plants, and the plants are thereupon subjected to increasingly vigorous shaking by walking bars having plural upstanding resilient inverted vee projections to remove the tomatoes. The tomatoes are freed of chaff, twigs and other foreign matter and are then carried on a pair of main sorting conveyors past sorters who remove culls. At the same time the clods and loose tomatoes pass countercurrently by the same sorters, some of whom select the good loose tomatoes and place them onto the main sorting conveyor while the loose culls and clods are conveyed to the ground for disposal.
