Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a first sink plate having a rearwardly inclined position for guiding a first object to a lower first object collecting device from the rear side, and a second object collecting a lower object. The present invention relates to a threshing apparatus provided with a second guide wall having a rearwardly inclined position for guiding the apparatus to flow downward from the front side, which is provided adjacent to the front and rear.

[0002]

2. Description of the Related Art The rate of occurrence of cut straw, which is the second crop, varies depending on the type of crop, such as relatively little when threshing rice and more when threshing wheat. Conventionally, the first sink plate is slidably provided on the first object guide wall in the inclination direction thereof, and an operator can slide the first sink plate from a dust outlet at the rear end of the apparatus. An operation unit is provided on the rear end side of the sink plate, and when threshing rice, the first sink plate is raised rearward and extended more rearward than the top of the first thing guide wall in the inclined posture to increase the recovery rate of the first thing, When threshing wheat, the top of the first sink was stopped near the top of the first thing guide wall to increase the recovery rate of broken straw.

[0003]

According to the above conventional construction, since the dust outlet at the rear end of the apparatus is not so large, an operator puts his hand into the dust outlet and slides the first sink plate. In such a method, the operation is troublesome. It is conceivable that the first sink is slid from one of the side plates. However, in this structure, it is difficult to transmit the operation force of the operator to the first sink, and it is almost impossible to realize.

The present invention has been made in view of the above circumstances, and an object of the present invention is to improve the operability of a switching operation when switching a state in which a first sink plate is extended rearward and a state where it is not extended.

[0005]

[Means for Solving the Problems]

[Structure] The characteristic structure of the invention according to claim 1 is that, in the recovery unit of the threshing device described at the beginning, an extended flow plate that extends the first flow plate backward is provided on the rear end side of the first flow plate. It is provided so as to be swingable around the left and right horizontal axes, and its extended flow plate can be freely switched between a state located on the extension of the first flow plate and a state where it has fallen down to the second guide wall side. Then, a holding mechanism for inserting a connecting tool connected to at least one of the left and right ends of the extended flow plate into an arc-shaped long hole provided in the side plate to hold the connecting tool at a desired swing position. The extension flow plate is configured so that the posture of the extension flow plate can be adjusted and fixed steplessly, and a closing plate that closes the long hole over the entire swing range of the extension flow plate is provided on the extension flow plate. .

A feature of the invention according to claim 2 is that, in the invention according to claim 1, the first flow plate and the extended flow plate are integrally formed of a resin material, and the first flow plate and the extended flow plate are formed integrally. Is formed in a thin hinge.

[Operation] According to the configuration of the first aspect, the following operation can be obtained. When the rice is threshed, the connecting tool is moved upward along the long hole of the side plate, and the extended flow plate is swung accordingly to be positioned on the extension line of the first flow plate. Then, the connecting tool is held by the holding mechanism at that position. As a result, the first sink plate is extended rearward, and the recovery rate of the first object to the first object recovery device side can be increased.

[0008] When threshing wheat, the connecting tool is moved downward along the long hole of the side plate, and the extended flow plate is swung accordingly to fall down on the second guide wall side. Then, the connecting tool is held by the holding mechanism at that position. As a result, the extension portion of the first sink plate is eliminated, and the recovery rate of the broken straw to the second product recovery device side can be increased.

As described above, in order to switch between the state in which the first flow plate is extended rearward and the state in which it is not extended, only the extended flow plate is operated differently from the prior art, and the operation is performed by connecting the connecting tool. The operator can easily transmit the operating force even if the operation is from the outside of one of the left and right side plates through the swing operation around the center of the left and right horizontal axes via it can.

In the above case, the holding mechanism can hold the connecting member at a desired swinging position and can adjust and fix the posture of the extension flow plate in a stepless manner. Even if it is small or large,
The situation can be appropriately dealt with. Since the closing plate for closing the long hole is provided on the extended flow plate over the entire swing range of the first flowing plate, the first and second products can be prevented from leaking out of the apparatus from the long hole.

According to the second aspect of the present invention, in addition to the effect similar to the operation of the first aspect, for example, the first flow plate and the extended flow plate are formed of a metal plate. As compared with a structure connected via a hinge, the weight can be reduced, and the extended flow plate can be further easily rocked, and can be manufactured at a low cost.

[Effect] Therefore, according to the first aspect of the present invention, it is possible to improve the operability of the switching operation when switching between the state where the first sink plate is extended rearward and the state where it is not extended.

According to the structure of claim 2, in addition to the effect similar to the effect of the structure of claim 1, the operability of the switching operation can be further improved and the manufacturing cost can be reduced. The price was reduced.
