An assembly for rotating a chain or toothed belt includes a shaft and a sprocket rotatably mounted on the shaft. The sprocket includes a plurality of teeth configured to engage the chain or toothed belt. The assembly further includes a shield assembly covering at least a portion of the sprocket. The shield assembly has an interior groove formed therein defining an enclosed interior space. Each of the teeth of the sprocket rotate through the enclosed interior space during a full rotation of the sprocket.

A method and system for controlling the quality of harvested grains include capturing, by one or more image sensors, one or more images of material at a sampling location within a grain elevator of the combine harvester. The captured images are defined by a set of image pixels represented by image data and having a classification feature indicative of grain or non-grain material. One or more controllers receive the image data associated with the one or more images captured by the image sensor(s) and select a sample image defined by a subset of image pixels of the set of image pixels. The controller(s) apply a convolutional neural network (CNN) algorithm to the image data of the subset of image pixels of the selected sample image to determine the classification feature. The controller(s) analyze the determined classification feature to adjust an operational parameter of the combine harvester.

A monitoring system for a combine harvester. The monitoring system includes a sensor configured to provide a measurement wave to a flow of crop residue on the harvester and to receive a response wave from the flow of crop residue. The monitoring system further includes a processor having an input terminal for receiving a response signal of the sensor representative of the response wave. The processor is configured to determine a crop parameter associated with the density of the flow of crop based on the response signal of the sensor. The processor further has an output terminal for outputting a density signal representing the crop parameter.

Selectively removable nozzles for inclusion into a grain conveyor are disclosed. The nozzles may include a ramp and a sidewall coupled to the ramp. The ramp may conform to an inner surface of a conveyor housing and produce a constriction within the housing. The sidewall may also conform to the inner surface of the conveyor housing. The ramp may also include a recess that extends along the sidewall. The recess may receive a shaft of the conveyor. One nozzle may be replaced with another in order to accommodate different harvesting conditions. The ramp compresses grain traveling through the conveyor to provide a continuous flow of grain. The continuous flow of grain provides for accurate measurements of grain characteristics by a sensor located adjacent to the flow of grain.

An agricultural vehicle including at least one threshing rotor and an auger bed located underneath the at least one threshing rotor. The auger bed has a working position and a cleaning position. The auger bed includes a frame, a plurality of augers rotatably coupled to and supported by the frame, and a trough portion moveably connected to the frame. In the working position the bottom surface of the trough portion is positioned underneath the plurality of augers and in the cleaning position the entire trough portion is moved relative to the frame so that the bottom surface of the trough portion is not positioned underneath at least a portion of the plurality of augers, creating an open space underneath the portion of the plurality of augers for allowing an unwanted material to pass therethrough.
