Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a narrow guide attachment device for a harvesting machine such as a combine harvester or a reaping and binding machine.

(b) Prior art Conventionally, as shown in Fig. 5, a grain culm pulling body is provided at the rear of the weeding body, and the front part of a narrow guide is rotated around the longitudinal axis at the rear of the weeding body on the side. A harvester is detachably attached to the harvester, and the rear portion thereof is also supported to rotate around an axis in the front-rear direction, and as shown in Fig. Harvesting machines are already known in which a combing cutting body is provided as an attachment on the outside of the triggering body.

(c) Problems to be solved by the invention In the known harvesting machine, when installing the combing over-weed splitter of the harvesting machine shown in Fig. 5, the installation position of the front part of the narrow guide is different, so it is difficult to install it at the rear part. It is necessary to attach a plate or other reinforcing member to the section, and the auxiliary member may be lost, and it is troublesome to attach and detach it.

In addition, when changing the narrow guide to the state shown in Figure 5 or 6, the pivot pin at the tip protrudes rearward, so the narrow guide itself must be attached and detached each time. At that time, it was also troublesome to attach and detach the rear support section.

(d) Means for solving the problem The present invention is equipped with a reaping device consisting of a plurality of weed cutting bodies, a plurality of grain culm pulling bodies, and a cutting blade arranged in that order on the front part of the machine. In a harvester with a narrow guide installed along the outside of the machine from the rear of the weeding body,
The front part of the narrow guide is loosely fitted into a hole in the front and back direction of a locking plate protruding from the front part of the frame so as to be rotatable and removable, and a mounting rod extends rearward from the front lower part of the narrow guide. A horizontal adjusting plate fixed to and hanging down from 21 is superimposed on a plate provided in the horizontal direction while being positioned in the vertical direction, and the plate and the adjusting plate are rotated about an axis in the front and back direction. The plates are connected to each other so as to be movable and maintain their positions, and a receiver protruding from the plate surface of the plate body is rotated in a substantially horizontal direction by a vertical connecting pin that can be inserted into and removed from a mounting plate integrated with the frame. By pivoting like this, when attaching or removing the combed weeding plant as an attachment, there is no need for an auxiliary member to change the posture of the narrow guide as in the past, and it is easy to attach and detach the narrow guide. The above-mentioned problem was solved by making it possible to perform the following steps.

(e) Action When attaching the combing weeding body as an attachment to a harvester that has only a narrow guide on the side of the machine, or conversely, when removing the combing weeding body,
When the pin is removed, the middle part of the narrow guide can be removed from the frame, so the narrow guide can be removed by simply pushing it forward.The direction of the narrow guide will be different when the combed weeding section is installed or removed, but the direction of the narrow guide will be different. Since the narrow guide rotates in a substantially horizontal direction about the vertical pin, it adapts to the above-mentioned change in angle.

(F) Example An example of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a threshing device mounted on one side of the machine having a traveling device, and the other side is provided with an operation panel 3, a driver's seat 5, a grain tank 6, an engine, etc. in order from the front. A grain culm conveying device 8, which also serves as a handling depth adjusting device, is interposed between the grain harvesting device 1 and the reaping device 7 installed in front of the grain culm conveying device 8.

The narrow guide 17 has a locking pin 18 facing rearward at the front end, and a mounting rod 21 that projects diagonally inward and downward at the rear end and has an adjustment plate 20 fixed to this projection is welded to the side. A weeding frame 22 protrudes rearward from the weeding body 10 of the section.
has a locking plate 23 that loosely fits and supports the locking pin 18 from the front, and is fitted and fixed to the front end of the reaping frame 25.

Further, the adjustment plate 20 of the reaping frame 25
A U-shaped fitting 26 with an opening on the outside is welded to the part facing the . The front surface is in contact with the adjustment plate 20.
It is composed of a plate body 28 that overlaps with the plate body 28 and a receiver made of a rectangular tube 29 welded to the rear surface, and the rectangular tube 29 is fitted into the mounting bracket 26 and connected to a vertical hole drilled therein. The connector 27 is configured to be able to rotate in a substantially horizontal direction relative to the reaping frame 25 by inserting a pin 30 from above and stopping the lower end with a spring pin 31.

Furthermore, one round hole of the adjustment plate 20 and the plate body 28
The pivot bolt 32 is inserted from the rear into the round hole and tightened with the nut 33, and the spring 36 is inserted into the round hole drilled toward the outside of the adjustment plate 20 and the long hole 35 drilled in the plate body 28. Since the interposed bolt 37 is inserted from the rear and tightened with the nut 38 to compress the spring 36, the narrow guide 1
7 can be rotated in and out, and when the connecting pin 30 is removed and pulled outward, the connecting tool 27
is separated from the attachment plate 26, and in this state, by pushing forward, the locking pin 18 at the tip can be pulled out from the hole in the locking plate 23.

Therefore, when installing the combing weeding body 40 having a large number of combing claws 39 on the outer surface of the grain culm pulling body 11 on the uncut land side, the front narrow guide 17 is removed before the combing weeding body 40 is attached. 40 as shown in FIG. 6, then insert the locking pin 18a protruding outward from the front of the narrow guide 17 into the hole of the locking plate 23 from the front, and attach the rectangular tube 29 of the connector 27. After loosely fitting into the metal 26, the connecting pin 30 is inserted, and the narrow guide 17 can be attached along the outside of the combed weeding body 40.

In the drawing, 41 is a side cover of the reaping device 7.
