Description

  The present invention relates to a combine.

  The conventional combine will be described as a self-removing combine using a dust-feeding treatment cylinder system. In this type of self-decomposing combine, the culm harvested and collected by the reaping part is sandwiched by the cereal conveying mechanism and conveyed to the rear threshing part. In the threshing section, a handling cylinder that is axially supported in the front-rear direction of the machine body is provided in the handling room, and a receiving net is stretched below the handling cylinder. In addition, a processing cylinder is provided in the processing chamber for communicating with the dust feeding port of the processing cylinder to reprocess the degranulated material of the processing cylinder, and a processing net is stretched below the processing cylinder.

  The threshing unit inserts the tip of the culm into the handling chamber while holding the cereal stock inherited from the reaping unit with a feed chain, and rotates the handling cylinder to handle a plurality of outer peripheral parts. Threshing is performed with teeth, and the cereals at the rear of the barrel are fed to the barrel and reprocessed.

  In the processing cylinder, normally 10-15% of the grains processed in the threshing section are made into a single grain and filtered. The threshing treatment and the reprocessed grain are dropped through the receiving net or the processing net to the lower swing sorting unit, and the waste after threshing is moved to the rear waste treatment unit for processing.

  The oscillating sorting unit is equipped with an oscillating sorter configured by attaching a feed pan, a sorting sieve wire, a chaff sheave, a grain sheave, etc. to the oscillating machine frame, a dust feed fan, a red pepper, etc. The first grain receiver that receives the grain and the second grain receiver that receives the second grain are provided, and the second grain is reduced by the second reduction conveyor onto the sorting screen of the swing sorter. Oscillating sorting and wind sorting processing is performed, and the first grain is transported and stored in the grain tank via the cereal conveyor, and can be taken out of the machine with the discharge auger. It is discharged from the mouth to the outside of the machine.

Conventionally, the processing cylinder inherits the threshing material at the rear of the handling cylinder and reprocesses it, and among the grains processed in the threshing part, normally 10-15% of the grains are made into single grains, and the downward swinging selection is performed through the processing net. It is discharged to the department. However, if the amount of threshing increases due to higher speed and higher efficiency of the combine unit, the processed material in the processing cylinder will be rough, the filtration of the processing net will be worsened, the amount of discharge to the outside will increase, Even if it is filtered on the dynamic sorting section, it will not be filtered with chaff sheave or the like, and the discharge from the third port to the outside of the machine will increase, making it difficult to achieve the normal single grain ratio. In particular, since many grains are concentrated directly under the processing cylinder, there is a possibility that the swing selection is poor.
