DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating dust in a threshing machine mounted on a combine or the like.

[0002]

2. Description of the Related Art A processing chamber in which a processing cylinder is provided along a lateral side of a handling chamber for accommodating a handling cylinder is provided side by side with the processing cylinder axis parallel to the handling cylinder axis. A threshing machine is known in which a dust outlet opening to the side is communicated with a starting end of a processing chamber (for example, see Japanese Utility Model Publication No. 1-63350).

[0003]

In general, this type of threshing machine is provided with only a dust outlet opening toward the outside at the end of the processing chamber.
Since dust from the processing chamber is suddenly discharged outside the machine,
There is a drawback that the extra flying loss of the goods becomes large. Therefore, the present invention reduces the dust from the processing chamber to the inside of the machine to prevent the third product from scattering outside the machine, and furthermore, despite the fact that the dust from the processing chamber is returned to the machine, The purpose is to perform an efficient sorting process.

[0004]

In order to achieve the above object, according to the present invention, there is provided a processing chamber disposed in a portion extending from a lateral side to a rear side of a handling chamber accommodating the handling cylinder. A processing cylinder is installed in parallel, a dust outlet opening at the end of the processing chamber is communicated with the beginning of the processing chamber, and a reduction opening that opens toward the inside of the machine at the end of the processing chamber. A discharge outlet is provided, and the reduction discharge outlet is opposed to a suction opening of a suction / dust exhaust fan disposed on the opposite side to the processing chamber.

[0005] Further, the reduction outlet is located above a terminal end of a swing sorting body disposed in a portion extending from the lower part to the rear of the handling chamber, and a suction port is provided for the reduction outlet. The suction / dust exhaust fan opposite to the above-mentioned dust exhaust device is disposed on the opposite side of the processing chamber with respect to the end of the swing sorting body.

[0006]

According to the threshing machine provided with the dust processing apparatus having the above-mentioned structure, unprocessed materials which do not fall from the handling chamber are sent from the dust outlet at the end of the handling chamber to the start end of the processing chamber. The processed material is processed by the rotation of the processing cylinder while being sent to the terminal end, and the leaked material from the processing chamber is also dropped into the swinging sorter, and the rocking sorter is also dropped together with the leaked material from the handling chamber. It will be subjected to a sorting action.

[0007] Dust and the like that do not leak from the processing chamber are returned to the body through the return outlet.
At this time, the suction force of the suction dust exhaust fan, whose suction port is opposed to the reduction discharge port, directly and efficiently acts on the dust discharged from the reduction discharge port. Among the objects, relatively light ones such as dust and straw waste are sucked by the suction / dust exhaust fan in a state of sliding upward on the upper surface of the swing sorter and discharged outside the machine. Therefore, despite the fact that the dust from the processing chamber can be returned to the body and re-sorted, the burden on the sorting unit such as the swing sorter can be reduced as much as possible. As a result, the second reduction amount from the sorting unit to the handling room was reduced, the threshing burden on the handling cylinder was reduced, and overall sorting performance and efficiency were improved.
