  • Patent number: 10927885
    Abstract: A steerable axle includes a housing defining a ball seat therein, a ball member received within the ball seat and defining a cutout portion to receive a portion of a ball bearing therein, an interstitial space defined by a surface of the ball seat and a surface of the ball member, and a ball bearing disposed within the interstitial space and received into the cutout portion of the ball member. The ball bearing moves within the interstitial space when the ball member rotates along the x or y axis, but is restricted from movement along the z axis. Restriction of movement of the ball bearing along the z axis results in a corresponding restriction of movement of the ball member along the z axis.

  • Patent number: 9795913
    Abstract: A system for removing particles from an air stream includes a housing having an air stream inlet at a first end, and an air stream outlet at a second end. The housing defines a flow path between the air stream inlet and air stream outlet. An agricultural device generating an air stream containing particles is in fluid communication with the housing, the air stream from the agricultural device being directed into the air stream inlet of the housing. An aggregator is disposed between the air stream inlet and the air stream outlet. The aggregator facilitates the aggregation of particles within the air stream. The aggregated particles fall from the aggregator by force of gravity.

  • Patent number: 9072224
    Abstract: A tree shaker for harvesting fruits, nuts, and other tree-borne products includes a mobile vehicle and a boom attached to the vehicle and offset at an angle with respect to a longitudinal axis of the vehicle. A boom pivot is provided along the length of the boom. The boom pivot is lockable such that when the boom pivot is unlocked the boom is free to pivot around the boom pivot, and when the boom pivot is locked the boom is fixed around the boom pivot.

  • Patent number: 8347595
    Abstract: A system for removing particles from an air stream includes a housing having an air stream inlet at a first end thereof and an air steam exhaust at a second end thereof. The housing defines a flow path between the air stream inlet and the air stream exhaust. At least one liquid introduction jet disposed between the air stream inlet and the air stream exhaust injects liquid droplets into the air stream. A scrubber disposed between the at least one liquid introduction jets and the air stream exhaust for removes smaller particles from the air stream.

  • Patent number: 8191346
    Abstract: A mobile harvesting unit which utilizes a high volume fan to separate crops from foreign matter, has a dust suppression system which substantially reduces particulates which are discharged with the fan exhaust. The dust suppression system has two stages. The first stage separates larger particles of foreign matter by deploying an air stream cleaning chain upstream of the fan. The second stage is contained within a air stream discharge duct. Within the air stream discharge duct, a liquid, such as water, is sprayed into the dust entrained air stream. The moistened air stream flows through a plurality of collection members which extend radially from a brush drum, where the moistened dust particles are accumulated on the collection members, such that the volume of dust particles contained within the air discharged from the harvesting unit is substantially reduced.

  • Patent number: 7765630
    Abstract: A low-profile sweeper that employs rotary brushes. The low-profile sweeper is especially suited for low overhead clearance applications, as typically found in nut harvesting. The low-profile sweeper has an armature for locating one or more brushes in an array, or attached to a conventional agricultural sweeper. The armature attaches to a chassis or frame of a steerable drive. When used in a parallel oriented array, the brushes rotate in the same, common direction and in substantially the same, common plane of rotation, slightly skewed to avoid contact between the brushes. The bristles of the radial brushes are emanate fro a central hub and are approximately parallel to the plane of rotation. A fan can be utilized to aid the pick-up action of the brushes. The fan is preferably mounted to direct an airstream to the area to be swept. Also, a spray-bar can be attached to the armature or alternatively to the chassis, to aid in dust abatement.

  • Patent number: 7412817
    Abstract: An apparatus for processing nuts and fruits, and more specifically, to a mobile apparatus that picks-up fruits and nuts, and similar products from the ground and conditions them, in bulk. The mobile apparatus conditions the fruits and nuts by removing debris with a combination of a belted conveyor and a high volume fan. The plenum of the apparatus is sized to achieve a constant velocity of air throughout the portions of the plenum in contact with the product, providing a constant suction to prevent the entrainment of product into the dust collection system. The processing apparatus can be utilized in a conditioner that picks-up and processes the product and then returns the cleaned and conditioned product to the floor of the orchard or grove. The processing apparatus can also be utilized in a harvester that picks-up and processes the product and then stores the product temporarily in a bin.
