  • Patent number: 7117661
    Abstract: A method and a system for collection of harvested tree-fruit having a collection device mounted on a hauled cart. For fruit collection, two arms are extended under the foliage of a tree to spread an apron hung between them, in a fruit receiving position. After harvesting is completed, and the apron contains the harvested fruit, the arms draw the apron away from under the tree, and swing through an arc of a circle to stop in a fruit discharge position, where fruit is discharged by gravity into the open top opening of the cart. Then, the arms are returned back from the discharge position to the fruit receiving position.

  • Patent number: 6978591
    Abstract: A vehicle-carried Tree-Trunk Shaker (TTS) for harvesting tree fruit is configured to prevent the transmission of vibrations from a vibration generator (4) to the TTS and to the vehicle, and for optimal shaking efficiently. Currently, TTSs are allowed to shake multi-directionally and chaotically, convey destructive vibrations to the TTS and to the vehicle, and have low harvesting efficiency. The remedy consists of shaking the trunk only in perpendicular to a pair of jaws (6, 8) clamping the trunk (T), with a unidirectional linear vibration generator vibrating transversally to the trunk. A beam (16) is configured to support the clamping jaws and the vibration generator to form a rigid structure restricted to swivel about a vertical pivot shaft (42) coupled to the vehicle. Thereby there is allowed but a single lateral degree of freedom of motion. Possibly, two vertical pivot shafts (42, 48) are used to that end.

  • Patent number: 6952914
    Abstract: A deflector (10) for collecting and guiding harvested tree-fruit is implemented for resilient recovery from collisions with obstacles in the field. The deflector is coupled in cantilever to boom harvester (4) mounted on a vehicle (2). The harvester has a telescopic boom (8) with a mobile portion (14) terminated by a clamp (6) able to move in horizontal and in vertical translation towards and along a tree trunk (T). The deflector is coupled to the mobile portion for slaved translation with the clamp. Implemented as an array of separate ribs (32) flexibly coupled together and made of flexible elastic plastic material such as fiberglass, the deflector is lightweight and flexes upon collision to resiliently recover shape after the collision. Being lightweight, the cantilever does not destabilize the vehicle. The structure and the materials of construction of the deflector prevent transmission of vibrations generated by the vibrator (12) used to shake the trunk when harvesting.

  • Patent number: 5816037
    Abstract: A tree-shaking apparatus includes a vibration mechanism of conventional design mounted on a movable, tilted frame support that serves to deflect falling harvest onto a conveyor and collection assembly, which is mounted on a separately movable frame support. The shaker assembly has a peaked configuration with grooves extending away from the peak and toward the shaker. A pair of upwardly inclined walls flank the peaked walls at their outer edges, preventing harvested material from rolling or bouncing off the sides of the frame. Uniting the two units are a series of cooperative, pivotable guides extending from each of the units. When extended during collection, the guides from the shaker assembly overlay the guides from the collection assembly, forming a substantially continuous downward path from the shaker assembly to the conveyor.

  • Patent number: 5473875
    Abstract: A tree-shaking apparatus that includes a pair of vibration units whose eccentric rotators turn at identical speeds but in opposite directions. During operation, rotation of the eccentric members is coordinated by a controller such that their asymmetric portions align at two diametrically opposed points but lie precisely out of phase during the remainder of the rotation cycle. This action causes the tree to shake along a single axis, specified by the chosen alignment of the rotators, with vibratory forces along all other directions canceling out. A controller systematically alters the direction and frequency of shaking and monitors the resulting change in vibration amplitude, selecting, as a final shaking axis and frequency, those which correspond to the largest amplitude.

  • Patent number: 5469695
    Abstract: A tree-shaking apparatus includes a vibration mechanism of conventional design mounted on a movable, tilted frame support that serves to deflect falling harvest onto a conveyor and collection assembly, which is mounted on a separately movable frame support. The shaking and collection units are brought separately to the tree, and unite with one another by means of rods that interlace during operation. In one embodiment, the rods associated with the shaking and deflection unit are selectibly extendible, while those associated with the collection unit flip into place and, upon completion of harvesting, flip back, thereby tipping any remaining harvest onto the conveyor.

  • Patent number: 4488683
    Abstract: Self-propelled irrigation equipment for large planted areas comprises a three-wheeled vehicle carrying a water distribution pipe supported by a telescopic girder, both girder and pipe extending across the vehicle to both sides. The pipe has evenly-spaced outlet openings which deliver water direct to the ground through flexible hoses open at their ends. Water is supplied to the equipment through a large, flexible hose stretched out on the ground between a fixed supply point and a large drum mounted on the vehicle. The vehicle is moved towards the supply point by means of a hydraulic actuator at a velocity proportional to the water quantity passing through the equipment to the ground, while the drum is rotated by a second hydraulic actuator at a rotational speed sufficient to wind up the hose on the drum at the rate of the vehicle's progress.
