Apparatus for cleaning narrow root crops including a roller device with two rotatable rollers forming a separating crop inlet, a separating track, a coarse material outlet, a fine material outlet, and a roller gap, and a conveyor downstream of the roller device. The separating track is formed by the top of the rollers and the fine material outlet is located below the roller gap. The coarse material outlet is at the end of the separating track opposite the separating material inlet. The roller gap is large enough to allow the narrow root crops to pass through to the fine crop outlet and small enough to retain coarse material that has a minimum dimension greater than the maximum root diameter, and transport it to the coarse material outlet. The conveyor is below the roller gap at the fine material outlet and receives all narrow root crops passing through the roller gap.

A separating device is provided for separating a harvested mixture of root crops and admixtures. The separating device includes at least one conveyor element which circulates in operation at least for supplying the harvested mixture to a separation region, or for discharging the root crops from the separation region in a conveying direction. The separating device includes at least one fluid flow generator and at least one directing device for directing a fluid flow in a fluid flow direction to the separation region. The directing device is at least realized in at least one directing portion by the conveyor element itself.

An apparatus for processing agricultural product having a main frame, a support for the main frame configured so that the main frame can be advanced in an operating direction over an area in which agricultural product is grown, and an operating system on the main frame configured to advance unearthed agricultural product intermixed with debris in a conveying direction in a conveying path between an input location and a first point of use. A first processing assembly a) advances unearthed agricultural product intermixed with debris in the conveying direction towards the first point of use; and b) allows intermixed debris to separate from the agricultural product as it is advanced in the conveying direction. A plurality of processing assemblies downstream of the first processing assembly separate intermixed debris in the form of vines from the agricultural product in different manners as the agricultural product is advanced in the conveying direction.

A crop cart cleaning and unloading system for cleaning debris such as dirt and rocks from a crop as the crop is being transferred between a hopper of a crop cart and a transport vehicle. The crop cart cleaning and unloading system generally includes a hopper for receiving a crop such as potatoes. The hopper transfers the crop onto a cleaning bed on which the crop is cleaned of debris, with the debris falling underneath the cleaning bed. The crop is conveyed across the cleaning bed as it is cleaned, with the cleaned crop being transferred from the cleaning bed onto an unloading conveyor. The unloading conveyor then transfers the cleaned crop to another location to be discharged, such as directly into a transport vehicle for further transport and processing.

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.

The invention relates to a cleaning device (2) for cleaning crops comprising a roller bed (4) comprising several rollers (3) rotatable about a rotational axis (3a), whereby gaps (10) are or can be provided between said rollers (3) in such a manner that impurities present together with the crop on an upper side (4a) of the roller bed (4) can be discharged through the gaps (10) while, at the same time, the crop can be kept on the upper side (4a), whereby the rollers (3) of the roller bed (4) can be driven in such a way that the impurities can be discharged through the gaps (10).

According to the invention, tappets (6) movable in the direction of conveyance (F) are arranged above the upper side (4a) of the roller bed (4) in such a way that crop present on the upper side (4a) of the roller bed (4) can be carried along by these tappets (6) in the direction of conveyance (F), whereby, to that end, said tappets (6) extend between at least two driver means (8; 12), whereby at least the tappets (6) arranged above said upper side (4a) of said roller bed can be moved by the at least two driver means (8; 12) in the direction of conveyance (F).
