Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a narrow guide for a combine.

[0002]

2. Description of the Related Art Conventionally, as a narrow guide of a combine, as shown in Japanese Utility Model Laid-Open Publication No. 7-39344, a narrow guide is known which is divided into front and rear sides. It is known that a front narrow guide and a rear narrow guide on the rear side are connected via a connecting rod attached to a rear portion of the front narrow guide. However, the connecting rod is mounted to the front narrow guide via two front and rear mounting portions, and thus has a drawback that the mounting to the front narrow guide is not easy and the weight increases.

[0003]

A narrow guide of a combine according to the present invention for solving the above-mentioned problems is provided with a pre-processing unit 3 for cutting and transporting grain stalks in front of a traveling machine body 2 so as to be vertically movable. A narrow guide 1 made of pipe material extends from the rear of the weed body 4 in the processing section 3 along the lateral side of the traveling body 2.
The narrow guide 1 is divided into a front narrow guide 6 and a rear narrow guide 7 in the middle part, and the front narrow guide 6 is provided with the front narrow guide 6.
A connecting rod 11 for connecting the rear narrow guide 7 and an adjusting portion 12 for setting and adjusting the positions of the narrow guard 1 in the left-right direction.
The connecting rod 11 is combined with a straight portion 11a along the front narrow guide 6 and a curved portion 11b in which one end of the straight portion 11a is bent in a U-shape. It is made of an elastic material that can be elastically deformed, and the end of the curved portion 11b is inserted into the rear end of the front narrow guide 6, and the end of the curved portion 11b is elastically attached to the inner peripheral surface of the front narrow guide 6. The connecting rod 11 is elastically deformed so that the connecting rod 11 can be brought into contact with the front narrow guide 6.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. 1 and 2 are a side view and a plan view of a main portion of a narrow guide portion in a pre-processing portion of a combine. The narrow guide 1 is supported by a front portion of a traveling body 2 so as to be able to ascend and descend as in the related art. The processing unit 3 is provided from the rear of the weeds 4 on the uncut side to the side of the threshing unit (not shown) in plan view.

On the other hand, the narrow guide 1 is formed of a pipe-shaped member and is divided at an intermediate portion. The front end of the front narrow guide 6 on the front side is provided with a pin 8 at the rear of the weeding body 4. The rear end of the rear narrow guide 7 on the rear side is supported on the uncut side of the traveling body 2 via a support ring 13 so as to be rotatable vertically and horizontally. Thus, the narrow guide 1 is attached to the traveling body 2 side.

As shown in FIGS. 1 to 3, at the rear of the front narrow guide 6, a straight portion 11a along the front narrow guide 6 and one end of the straight portion 11a are formed in a U-shape. A rod-shaped connecting rod 1 including a curved portion 11b that is bent.
The front narrow guide 6 and the rear narrow guide 7 are connected via the connecting rod 11. That is, the connecting rod 11 is arranged such that the curved portion 11b is located at the rear end of the front narrow guide 6, and the annular connecting portion 7a provided at the front end of the rear narrow guide 7 is engaged with the curved portion 11b. It has been combined.

As a result, the front narrow guide 6 is swingably supported to the left and right and the front and rear with respect to the rear narrow guide 7, while the outer side of the narrow guide 6 (uncut ground side) from the traveling body 2 side. An adjusting rod 12 protruding toward the rear end, and an annular connecting portion 12 formed at the tip of the adjusting rod 12.
a is slidably inserted into and engaged with the linear portion 11a, and the adjusting rod 12 is moved back and forth to the uncut side of the traveling machine body 2 so that a narrow space between the stalks of the grain during storage or operation is obtained. It is configured so that the position of the guide 6 can be moved forward and backward.

Next, the structure for attaching the connecting rod 11 to the front narrow guide 6 will be described. As shown in FIGS. 2 and 4, the connecting rod 11 is provided at the rear end of the front narrow guide 6 where the end of the curved portion 11b is formed of a pipe as described above and the rear end is opened. Inserted and straight portion 11a
An attachment portion 11c provided at the front end of the front narrow guide 6 is detachably fixed to a fixing portion 6a formed at an intermediate portion of the front narrow guide 6, and is attached to the front narrow guide 6.

At this time, the connecting rod 11 is made of an elastically deformable member such as metal, and the end of the curved portion 11b is inserted into the end of the front narrow guide 6 as shown in FIG. In, the mounting portion 11c is located outside the fixing portion 6a. Then, the connecting rod 11 is elastically deformed so that the mounting portion 11c is overlapped with the fixing portion 6a, and the mounting portion 11c and the fixing portion 6a are fixed by bolts 14 or the like, so that the connecting rod
1 is fixed (removable) to the front narrow guide 6, and the end of the connecting rod 11 (curved portion 11b) is connected to the connecting rod 1.
Due to the elastic deformation of the front narrow guide 6, the narrow guide 1 (front narrow guide 6) and the connecting rod 11 are attached elastically to the inner peripheral surface at the rear end of the front narrow guide 6. .

According to the structure described above, for example, when the combine turns to move to the next stroke during the mowing operation,
When the pre-processing unit 3 is lifted upward, the front narrow guide 6
Is rotatably supported in a horizontal direction, and can be freely rotated in the horizontal direction.
Is formed in an annular shape and is engaged and connected to the curved portion 11b of the connecting rod 11, so that it can freely rotate in the vertical direction, and furthermore, the connecting portion 1 of the adjusting rod 12 is connected to the linear portion 11a of the connecting rod 11.
2a penetrates and freely moves in the longitudinal direction.

Further, in order to advance or retreat the position of the narrow guide 6 depending on the interval of the grain during storage or operation, the total length of the narrow guide 1 is changed by moving the adjusting rod 12 to the side of the traveling machine body 2. Therefore, the narrow guide 1 follows the elevation of the pretreatment device 3 without hindering the elevation of the pretreatment device 3.

On the other hand, since the connecting rod 11 is attached to the front narrow guide 6 as described above, the mounting structure of the front narrow guide 6 and the connecting rod 11 is simple, and the fixing portion by the bolt 14 is provided. Because it is only the front, the connecting rod 1
1 and front narrow guide 6 can be easily attached.
Cost reduction and weight reduction can be achieved. In addition, since the connecting rod 11 is biased in the return direction, the shape is stabilized, and the dimension can be easily controlled.

[0013]

According to the structure of the present invention constructed as described above, one end of the connecting rod is inserted into one end (rear end) of the front narrow guide, and the tip of the connecting rod is fixed to the front narrow guide. As a result, since the connecting rod is attached to the front narrow guide, the mounting structure between the front narrow guide and the connecting rod is simplified, so that the connecting rod can be easily attached to the narrow guide, and the cost can be reduced. In addition, there is an effect that the weight can be reduced. Further, since the connecting rod is biased in the return direction, there is an advantage that the shape is stable and the dimension can be easily controlled.
