An impact processing system 10 having a central opening 12 enabling material flow into a primary impact zone 14 in which is located an impact mechanism 16 rotatable about a rotation axis 18. An impact structure 20 provided with a plurality of holes 22 surrounds the impact mechanism 16. The rotatable impact mechanism 16 impacts material entering the primary impact zone 14 from the central opening 12 and accelerate the impacted material in a radial outward direction toward the impact structure 20 to effect fragmentation of the impacted material so that when sufficiently fragmented the material is able to pass through the holes 22. An optional outer structure 30 is radially spaced from the impact structure 20 and may comprise one or more segments that cumulatively extend about the axis of rotation 18 for an angle from 30 and 270 inclusive. A rotatable set of impact members 50 may be located between the impact structure and the outer structure. One or more gaps 28 may be provided in the impact structure 20 to allow the passage of large and/or hard objects that cannot otherwise be fragmented. The outer structure 30 is positioned to span across the gaps 28 so that material passing there thought is directed onto the outer structure 30.

An orchard sanitation implement disposes of unharvested nuts which may otherwise be utilized as habitat and food for navel orangeworms. Unharvested nuts are lifted from the orchard floor and delivered to a storage bin of the implement. Once received within the storage bin, the unharvested nuts are separated from other orchard debris by a looping belt which allows unharvested nuts to fall through, but other orchard debris is conveyed outside of the storage bin for deposit either into a container or back to the orchard floor. The unharvested nuts fall through openings in the looping belt, through an outlet at the bottom of the storage bin and into a shredding unit attached to the outlet. The shredding unit shreds and pulverizes the unharvested nuts into a composition which is too small to be utilized by navel orangeworms for habitat or a source of food.

A roller assembly for smoothing an expanse of granular media such as golf bunker sand, snow, horse race track dirt, or other media. The assembly has one or more rollers having a longitudinal axis. Each roller includes wires spaced from the axis to define a roller surface. Each wire is resiliently flexible to distort inwardly in response to force of contact on, and to recover during release of force from, the granular media as the roller rotates about the axis on the granular media. A shaft extends along the axis of the roller assembly between the arms of a yoke with a handle extending therefrom. As the roller surface traverses the media, at least some of the media is flung outwardly of the roller, smoothing the expanse. The roller assembly may be manually operated or may be towed behind a towing apparatus.

Provided is a highly reliable, cost-effective scattered object collection system that can determine the correct position of each scattered object on the ground, such as a ball, and efficiently collect scattered objects by reducing unnecessary traveling of an autonomous collector. The scattered object collection system includes an autonomous collector that performs a collecting operation by picking up balls B while traveling in a work area W and a collector management unit that manages the autonomous collector. The collector management unit acquires positional information on the autonomous collector, identifies an actual position where each ball B was picked up in the work area W using the acquired positional information, and allows the autonomous collector to perform a collecting operation in a place having a high density of balls B with higher priority than a place having a low density of balls B using the identified actual positional information on each ball B.

Systems and methods for separating harvested crop product from twigs, dirt, dust, and other debris. A disk to be used in a harvester includes a first segment and a second segment and is configured to cooperate with adjacent disks axially mounted on a common rotational shaft, and radially cooperate with disks mounted on a parallel rotational shaft. The disks are used in a roller assembly or a harvester, and gaps between cooperating disks remain effectively constant during operation.

An apparatus for collecting thorns, spines, prickles, seeds, burrs, and the like from the ground. Embodiments of the present disclosure include a roller for picking up thorns, spines, prickles, seeds, burrs, and the like from the ground, a scraper to remove the picked-up objects from the roller, and a collector tray to catch and collect the removed objects. In embodiments, the roller comprises a cylindrical foam roller. In embodiments, the scraper comprises a mesh screen rolled into a cylinder-like form and held adjacent to or against the roller. Objects that are removed from the roller may be ejected and/or fall into the collector tray for subsequent disposal.

The present invention provides an improved dust control system for removing debris and particulate matter from a fouled air stream. The system may be incorporated into crop harvesting equipment to eliminate the dust pollution generated by conventional harvesting equipment. The dust control system may use a multi-stage air filtering process that employs inertial separation techniques to eliminate particulate matter from the fouled air, without the need for water or electrostatic mechanisms to capture the fine particulates in the fouled air.

Systems and methods for replacing a removable assembly from a harvester for collecting and separating harvested crop product from twigs, dirt, dust, and other debris. A removable assembly for picking up harvested crop product and a removable assembly for separating the picked up harvested crop product from twigs, dirt, dust, and other debris are mounted to be changed out quickly in the field. A removable pickup assembly is received for removably mounting in the harvester by an inclined slot formed in a sidewall of the harvester body frame, so that the removable pickup assembly with the worn belt is lifted up and out and a replacement removable pickup assembly with a new belt is dropped into its place.

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.
