A conveyor comprises an endless belt and a belt return device. The endless belt comprises an upper run and a lower run and is configured to convey conveying material in a conveying direction. An intermediate space is defined between the upper run and the lower run. The belt return device facilitates transitioning of the endless belt between the lower run and the upper run. The endless belt defines at least one passage opening which allows the exit of at least a portion of an intermediate space material which is formed by a portion of the conveying material which has reached the intermediate space. At least a portion of the endless belt comprises a conveyor track and a passage track. The passage track defines the at least one passage opening. The conveyor track and the passage track are arranged side by side in the conveying direction.

A robotic service device for a robotic picking system grid. The robotic service device can be configured for driving to any location on the grid in order to restart malfunctioning robotic load handling devices or to perform maintenance operations or cleaning in situ. Additionally, the service device may be used to rescue robotic load handling devices operational in the picking system. The robotic service device can include a releasable docking mechanism to enable it to dock and latch on to malfunctioning load handling devices. A deployable, releasable electrical connecting device is shaped to conform to a charging, powering, or battery component of one or more of the load handling devices.

This disclosure provides a lifting system for a grain combine. The grain combine includes a plurality of paddles connected transversely to a chain. Each paddle includes an inner edge attached to the chain and an outer edge. The chain is driven by two toothed pulleys. The system also includes a housing with a lower feed opening and an upper discharge opening. The lifting system includes at least one paddle having a cleaning element attached to its outer edge. The cleaning element is adapted to contact at least part of the inner surface of the lifting system housing in which part of the surface has perforations.

A deduster is comprised of two sets (pairs) of counter-rotating dedusting brushes in co-operation with a vacuum system for saw dust removal from wooden lumber. In addition to these features, the deduster may feature a separate, movable, top brush assembly that can be easily adjusted for different board thicknesses and raised up to allow for clearing board jams and for pass-through if boards were to be run without dedusting. This deduster apparatus is modular, thereby allowing it to be positioned over an existing machine or a lumber board unscrambler machine such as a lugged unscrambler machine.

A system for wrapping a material around a bale in a baler includes a feed system to direct the material through a feed path. A knife mechanism with a fixed knife and a counter-knife alternately cuts the material, and moves out of the feed path for feed of the material. The feed system includes a roll element configured to direct the material between the fixed knife and the counter-knife when the counter-knife is moved out of the feed path. A cylindrical brush rotates freely and is disposed between the roll element and the knife mechanism, the brush having a cylindrical shape. The brush is configured to remove debris when rotated.

A deduster is comprised of two sets (pairs) of counter-rotating dedusting brushes in cooperation with a vacuum system for saw dust removal from wooden lumber. In addition to these features, the deduster may feature a separate, movable, top brush assembly that can be easily adjusted for different board thicknesses and raised up to allow for clearing board jams and for pass-through if boards were to be run without dedusting. This deduster apparatus is modular, thereby allowing it to be positioned over an existing machine or a lumber board unscrambler machine such as a lugged unscrambler machine. There is also a deduster for a board handling hopper.
