Description

[Detailed Description of the Invention] The present invention relates to a combine harvester that has a reaping section and a threshing section and performs operations from reaping to threshing.

Traditionally, combine harvesters have been constructed to perform all stages of harvesting work, and are extremely convenient machines for harvesting work, but conventional combine harvesters have been constructed specifically for harvesting work and cannot be used for other purposes. It was not configured. Therefore, conventional combine harvesters cannot be used for anything other than harvesting work, and are uneconomical because they can only be used for a short period of time throughout the year.

In view of these circumstances, the present invention aims to provide a combine harvester whose traveling function and reaping section lifting and lowering functions can be used more widely.

In order to achieve this object, the combine harvester of the present invention is provided with a spare bearing boss section below the pivot for supporting the reaping section frame, and the reaping section is configured to be removable from the machine body.

Because of this configuration, the reaping part can be removed and the lift platform can be attached via a parallel link pivoted to the pivot part and the spare boss part to use it as a simple forklift for transportation work, or to attach a plow, tiller, etc. This means that they can be used for each. By configuring the reaping section to be removable and providing a spare boss section in this way, the machine body can now be used for purposes other than harvesting work.

Examples and usage examples of the combine harvester of the present invention will be shown below.

As shown in FIG. 1, a combine harvester is comprised of a machine body 1 having running crawlers 2, a reaping section 3 at the front and a threshing section 4 at the rear.

As shown in FIGS. 2 and 3, the rear end of the frame 5 of the reaping section 3 is pivoted to a pivot 6 on the machine body 1 side so as to be able to swing vertically, and between the machine body 1 and the reaping section 3. It is configured to be moved up and down by a hydraulic cylinder 7 interposed therebetween. That is, left and right columns 8 are erected at the front of the fuselage 1, and a pivot 6 is formed by fixing a bearing 9, which is divided into upper and lower parts and both are bolted together, to the upper end of the column. A horizontal shaft 10 is fixed to the rear end of the frame 5 of the reaping section, and is fitted into the bearing 9. An engaging member 11 having a substantially ellipsoidal recess is fixed to the frame 5, and the recess contacts the tip of the rod 12 formed on the spherical surface of the hydraulic cylinder 7.
The reaping section 3 is configured to swing up and down as the hydraulic cylinder 7 expands and contracts.

Further, a spare bearing boss portion 19 is formed in the middle portion of the support column 8 of the pivot portion 6, and can be used as required.

Therefore, for example, as shown in FIGS. 4 and 5, it is possible to attach a lifting platform 20 that can be moved up and down in place of the reaping section 3. That is, the loading platform 20 is provided with a parallel link 21, and at the end of this parallel link 21 there are shafts 22, which are pivoted on the bearings 9, respectively.
and a shaft 23 pivotally supported by the spare boss portion 19. These shafts 22 and 23 are fitted into bearings 9 and 19, respectively, and are prevented from falling off by pins.

Further, an engagement member 11 similar to the above for receiving the rod 12 of the hydraulic cylinder 7 is fixed to the link 21,
It is configured to be raised and lowered by a hydraulic cylinder 7 for raising and lowering the reaping part.

In this manner, the pivot portion 6 and the rod 12 of the hydraulic cylinder 7, which are the points where the body 1 and the reaping section 3 are connected, are all configured so that the reaping section 3 can be easily connected and detached.
