Description

Combine {A COMBINE}

The present invention relates to a handling depth adjusting structure of a combine having a handling depth manual adjustment device for changing the position of the movable conveying mechanism and adjusting the handling depth by the threshing device by the operation of an operating lever provided near the control part. .

Conventionally, in the handling depth adjusting structure of the combine, it is an inexpensive form, and as described above, by manually adjusting the handling depth by the threshing device while changing the position of the movable conveying mechanism by the operation of the operation lever equipped near the control unit. There was something composed.

However, according to the above prior art, since the operation lever is arranged near the control unit having a limited space for arranging the handling depth from the control unit, the operation range of the operation lever is limited. As a result, there is an irrationality that the handling depth adjustment range that can be adjusted by the lever operation is narrowed. In addition, if the link ratio is increased to solve this irrationality, the operating range of the operating lever can be limited and a wide handling depth adjustment range can be obtained, which leads to an unreasonable rationality of the operation lever.

An object of the present invention is to provide a handling depth adjustment structure of a low-cost type for manually adjusting the handling depth, and to obtain a wide handling depth adjustment range without being unreasonably expensive to operate.

In order to achieve the above object, according to the present invention, a traveling gas; A control unit of the traveling body; A pre-processing unit installed at the front of the traveling body to mow plant stems; A supply conveying apparatus for conveying the stems harvested by the pretreatment unit to the threshing apparatus; A combine having a threshing device for processing harvesting stems conveyed from said feed conveying apparatus, wherein said supply conveying apparatus is a movable conveying mechanism which is swingable within the handling depth adjustment range for adjusting the handling depth of said harvesting stem by said threshing apparatus. In order to oscillate the movable conveyance mechanism, a combine is provided with a handling depth manual adjustment device having an operating lever close to the control unit which can swing in a short handling direction or a deep handling direction, so that the handling depth adjustment range Within the range, an adjustment area displacement mechanism for displacing the handling depth adjustment area by the operation lever narrower than the handling depth adjustment range in the shallow handling direction or the deep handling direction is provided, and the operating mechanism of the adjustment area displacement mechanism is provided. Is arranged at a position operable by the control unit.

(Action)

With such a structure, since the operation lever is arranged near the limited control unit in the arrangement space so as to perform the handling depth adjustment from the control unit, the operation range of the operation lever is limited. In the configuration of the present invention, the handling depth adjusting region which can be adjusted by the operation of the operating lever remains narrow, but the handling depth adjusting region can be displaced in the handling depth adjusting direction by the adjusting region shifting mechanism. Since the handling depth adjustment amount corresponding to each operation position of the operation lever can be increased or decreased uniformly, a wide handling depth adjustment range can be obtained as a result. In this way, it is not necessary to increase the link ratio in order to obtain a wider handling depth adjustment range, and thus does not cause the unreasonableness of the operation lever being heavy.

Further, for example, if the operating tool for operating the adjustment area displacement mechanism is arranged in a position where the operation from the control part is impossible, the operation can be performed from the control part when the handling depth adjustment area is displaced in the handling depth adjustment direction. In the same way as the handling depth adjustment, the displacement operation in the handling depth adjustment direction of the handling depth adjustment area is also performed by the operation from the control unit, so that the handling area is widened by installing the adjustment area displacement mechanism. The handling depth adjustment operation is easily performed by the operation from the control unit over the entire depth adjustment range.

(effect)

Therefore, in spite of the inexpensive handling depth adjusting structure for manually adjusting the handling depth, it is possible to obtain a wide range of handling depth adjustment without causing the operation to be heavy.

Moreover, the operability at the time of carrying out the handling depth adjustment in the wide range was aimed at.

In a preferred embodiment of the present invention, it is preferable that the adjustment region displacement mechanism is configured to enable the displacement adjustment of the handling depth adjustment region by rotation adjustment of a screw provided on the operation shaft of the operation tool.

(Action)

With this structure, the handling depth adjusting region can be displaced steplessly in the handling depth adjusting direction, so that a delicate displacement operation of the handling depth adjusting region in the handling depth adjusting direction is performed.

(effect)

Therefore, in addition to obtaining a wide handling depth adjustment range without causing the operation to be heavy, the precise displacement operation in the handling depth adjustment direction of the handling depth adjustment area according to the working situation is performed.

In a preferred embodiment of the present invention, the handling depth manual adjustment device is in communication with the operation arm which is swingable around the transverse center integrally with the operation lever by swinging the operation lever, and the operation arm and the movable conveyance mechanism are linked. And an adjustment rod which makes the displacement of the handling depth adjustment region possible by changing the relative angle of the operation arm with respect to the operation lever by the adjustment operation of the operation tool.

(Action)

With this structure, the displacement of the handling depth adjustment area in the handling depth adjustment direction is performed by changing the relative angle between the control lever and the operating arm provided near the control section. In this case, the configuration can be simplified.

(effect)

Therefore, it is an inexpensive handling depth adjustment structure that performs manual handling depth adjustment, and improves the operability at the time when the handling depth adjustment is performed in a wide range, and also simplifies its configuration. In a preferred embodiment of the invention, a linking arm which is swingable integrally with the operation arm around the transverse axis is provided, and the operating arm of the control area displacement mechanism is connected to the linking arm, wherein the linkage is connected to the operating arm. And change the relative angle of the operating arm relative to the operating lever by swinging the arm around the transverse center to change the relative angle of the operating arm relative to the operating lever. The said operating tool was arrange | positioned at the area | region of the said operation lever, The combine characterized by the above-mentioned.
