Abstract

PURPOSE:To facilitate the maintenance of even a side part of a grading shelf part by rotating a grain culm nipping and conveying feeder to the outer lateral side and opening a part or all of the lateral part of the grading shelf. CONSTITUTION:This thresher for a combine harvester is obtained by installing a threshing drum 1 at a position in an upper part of the interior, constructing a grading shelf 2 at a position in a lower part of the threshing drum 1 and providing a grain culm nipping conveying feeder 4 for feeding and conveying grain culms to the thresher 3 in the lateral part of the thresher 3. In the thresher, the grain culm nipping and conveying feeder 4 is constructed so as to freely rotate to the outer lateral side relatively to the thresher 3 with the front side thereof as a fulcrum and a part or all of the sidewall closing the lateral part of the grading shelf 2 is simultaneously integrally installed. Thereby, a part or all of the lateral part of the grading shelf 2 is constructed so as to be opened by rotating the grain culm nipping and conveying feeder 4 to the outer lateral side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine threshing device.

[0002]

2. Description of the Related Art As described in Japanese Laid-Open Utility Model Publication No. 1-167839, which is publicly known, a grain-culling holding and feeding device provided in a combine threshing device is configured to be rotatable outward with a rear side as a fulcrum. There is something. This is for opening the side part of the threshing device by rotating the grain-culling holding and feeding device located on the side part of the threshing device to the outside, thereby facilitating the internal maintenance.

[0003]

In the above-mentioned conventional combine threshing device, the grain culling holding and feeding device provided therein is rotatable outward with the rear side as a fulcrum, and therefore the front side is wide open. However, the rear side hardly opens. Therefore, the maintenance space created by this becomes smaller toward the rear, and maintenance of the rear part of the sorting shelf provided inside the threshing device becomes difficult.

Further, in the conventional structure, even if the grain-culling holding and feeding device is rotated outward, the side of the sorting shelf provided inside the threshing device is not opened. Therefore, when attaching / detaching the selection shelf to / from the thresher, it is difficult to connect or disconnect the sheave angle adjusting member provided on the side surface of the selection shelf and the wire for remote operation. In, the defect point was left.

[0005]

In order to solve the above-mentioned problems, the present invention takes the following technical means.
That is, the threshing device 1 is provided at the upper position inside, and the selection shelf 2 is provided at the lower position of the handling drum 1 to configure the threshing device 3, and the grain culm is supplied to the side part of the threshing device 3 In a combine threshing device provided with a grain-culling holding and feeding device 4, the grain-culling holding and feeding device 4 is configured to be rotatable outward with respect to the threshing device 3 with its front side as a fulcrum. A part or all of the side wall that closes the side of the sorting shelf 2 is integrally provided, so that the side of the sorting shelf 2 is partially rotated by the outward rotation of the grain-culling holding and feeding device 4. Alternatively, the present invention is a combine threshing device characterized by being configured so that all of them are opened.

[0006]

In the combine threshing device according to the present invention, the grain-culling holding and feeding device 4 is configured to be rotatable outwardly with respect to the threshing device 3 with its front side as a fulcrum. Therefore, the grain holding and feeding device 4
When you rotate the to the outside, the rear side opens greatly, and the maintenance space created by this also increases toward the rear,
Maintenance of the rear part of the sorting shelf 2 provided inside the threshing device 3 can be easily performed.

Further, the grain-culling holding and feeding device 4 is integrally provided with a part or all of a side wall that closes a side portion of the sorting shelf 2. Therefore, the grain holding and feeding device 4
Is rotated outward, a part or all of the side portion of the sorting shelf 2 is opened. Thus, when the sorting shelf 2 is attached to or detached from the threshing device 3, it is easy to connect or disconnect the sheave angle adjusting member provided on the side surface of the sorting shelf 2 to the remote operation wire. The maintenance work on the side surface can be easily performed.
