A tumble trimmer system having a tumbler barrel with a perforated axle adapted for introducing a freezing agent such as liquid carbon dioxide or other liquefied gas adapted to flash freeze the plant material when infused into the mesh tumbler barrel, the mesh tumbler barrel adapted with mesh netting or screening for trimming and/or separating plant material enclosed therein, and with an open funnel or chute positioned below the tumbler barrel adapted to catch and direct trimmed and/or separated plant material exiting the tumbler barrel into a bin or container positioned under the funnel or chute, wherein the perforated axle comprises a plurality of perforations positioned around a circumference of and along an entire length of the axle.

The present invention refers to an automatic grain processing apparatus comprising, in an integrated manner, that is, in a single apparatus, the following units: a cleaning unit (2); a drying unit comprising a dryer (18), a grain weighing and classification unit; and a grain packaging and labelling unit. The present invention also refers to a grain integrity monitoring and tracking system, comprising one or a plurality of sensors arranged in a package and configured to measure the properties, such as temperature and/or moisture and/or pressure and/or vacuum of the packaged grains, together with the location of the load; and at least one communication module configured to receive the data from one or a plurality of sensors and configured to transmit and store the information from said one or a plurality of sensors in a cloud or any high-performance repository. Said sensors arranged in the package (34) can identify exactly how, when and where the load, that is, the packaged grains, is stored, the temperature, vacuum and pressure conditions of the grains, and also provide agile location responses for monitoring by the end client.

A rotary cleaning system for a combine harvester that includes a hollow drum having a plurality of apertures along at least a portion of a length of an exterior surface of the drum, the drum having a feeding end configured to receive a harvested crop and a discharge end configured to expel chaff from the harvested crop and a guiding vane positioned in an interior of the drum, wherein one of the drum and the guiding vane is configured for rotation while the other one of the drum and the guiding vane is stationary to expel grain through the plurality of apertures in the drum. A feeding mechanism can be attached to supply the crop to the hollow drum. A fan can be attached to the rotary cleaning system to generate an air flow stream. A plurality of fingers can be positioned in the drum.

A threshing system for a combine harvester includes a support bracket that is configured to be attached to a threshing rotor cylinder of the threshing system and a rasp bar that is configured to be mounted to the support bracket. A channel is formed in one of the rasp bar and the support bracket for receiving a surface of the other of the rasp bar and the support bracket, wherein engagement between the channel and the surface limits movement of the rasp bar on the support bracket.

A harvesting machine including a cutting head configured to provide cut crop for threshing. The harvesting machine includes a conveyer disposed adjacent to the cutting head and configured to move the cut crop to be threshed along a path. A thresher is configured to thresh the cut crop to provide threshed grain from the cut crop. A separator is disposed adjacently to the thresher and is configured to separate debris from the threshed grain. A feed accelerator is disposed between the conveyor and the thresher, wherein the feed accelerator is configured to advance the cut crop along the path from the conveyor to the thresher. A pre-threshing device is disposed adjacently to the feed accelerator, wherein the feed accelerator interacts with the pre-threshing device to provide threshed grain, and the pre-threshing device is configured to collect the threshed grain before the remaining cut crop is threshed at the thresher.

A spreader of a combine for conveying crop residue rearwardly from a rotor assembly includes a frame coupled to the combine and has a top portion adapted to receive a portion of crop residue during a harvesting operation. An impellor includes one or more blades for rotatably conveying crop residue rearwardly, and an actuator is controllably moved between an extended position and a retracted position. The actuator is pivotally coupled to the combine. A linkage assembly is pivotally coupled to the actuator at one end and to the frame at another end. The spreader is disposable in a first position when the actuator is in the extended position, and the spreader is disposable in a second position when the actuator is in the retracted position. A movement from the extended position to the retracted position induces pivotal movement of the spreader from the first position to the second position.

A threshing system for a combine harvester includes a support bracket that is configured to be attached to a threshing rotor cylinder of the threshing system and a rasp bar that is configured to be mounted to the support bracket. A channel is formed in one of the rasp bar and the support bracket for receiving a surface of the other of the rasp bar and the support bracket, wherein engagement between the channel and the surface limits movement of the rasp bar on the support bracket.

A rotary cleaning system for a combine harvester that includes a hollow drum having a plurality of apertures along at least a portion of a length of an exterior surface of the drum, the drum having a feeding end configured to receive a harvested crop and a discharge end configured to expel chaff from the harvested crop and a guiding vane positioned in an interior of the drum, wherein one of the drum and the guiding vane is configured for rotation while the other one of the drum and the guiding vane is stationary to expel grain through the plurality of apertures in the drum. A feeding mechanism can be attached to supply the crop to the hollow drum. A fan can be attached to the rotary cleaning system to generate an air flow stream. A plurality of fingers can be positioned in the drum.

A concave for an agricultural combine includes threshing beds carried by a base frame and forming openings therebetween for grain to pass through. Each threshing bed includes a first end, a second end, a length from the first end to the second end, an inner extremity, an outer extremity, and a separating grate extending across one of the openings for separating grain from threshed crop material. The separating grate extends along the length between the first end and the second end, is between the inner extremity and the outer extremity and includes grate openings and spaced-apart bars. The bars are between adjacent grate openings and include struts each connecting two adjacent parts of the separating grate between adjacent grate openings and severed bars each including bar segments extending inwardly toward one another to respective free ends on either side of a gap between adjacent grate openings.
