Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a threshing machine with a processing drum, which enables smooth and efficient transfer of the dust sent from the handling chamber to the processing chamber and the treatment and transfer of the dust in the processing chamber. .

[0002]

[Prior art]

 Conventionally, a processing chamber with a handling cylinder mounted on the upper side of the sorting chamber and a processing chamber with a processing cylinder mounted on the sorting chamber are connected side by side through a dust inlet in the rear of the handling chamber. In the thresher, if the distance between the handling chamber and the processing chamber is wide so that the grains leaking from both adjacent leaking bodies of the juxtaposed chamber and the processing chamber do not interfere with each other, dust will not be sent. The flow of dust passing from the handling chamber to the processing chamber via the mouth becomes poor, and the dust is likely to accumulate in the dust inlet port and cause clogging. If the gap between the two is narrowed so that the flow of dust at the dust discharge port does not become stagnant, the grains that leak from both the leak chambers of the handling chamber and the processing chamber interfere with each other, and the leakability is reduced. There was a problem of lowering.

[0003]

[Problems to be solved by the present invention]

 The present invention has been made to improve the problems of the above-mentioned conventional threshing machine with a processing cylinder, and it is possible to reduce the flow of dust through the dust discharge port without narrowing the distance between the handling cylinder chamber and the processing cylinder chamber. It is an object of the present invention to provide a threshing machine with a processing drum that is smooth and that efficiently performs a series of threshing processing operations.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a handling chamber having a handling cylinder mounted thereon and a treatment chamber having a processing barrel mounted thereon, which are communicated with each other through a dust supply port at the rear of the handling chamber. In a threshing machine with a processing cylinder arranged at least in parallel, the processing cylinder is a spiral processing cylinder, and the spiral teeth of the spiral processing cylinder are provided with processing teeth protruding from the outer periphery of the spiral at appropriate intervals, and It features a threshing machine with a processing barrel in which the treated teeth of the spiral part facing the dust inlet at the rear of the handling room are made taller than the treated teeth of other parts.

[0005]

[Action]
