Description

[Detailed Description of the Invention] This invention relates to a combine harvester, and more particularly, to a combine harvester in which a seeding machine having a groove cutting plate is attached to a reaping section located at the front of the machine body.

Conventionally, in a combine harvester, a seeding machine consisting of a seed tank with a metered feed device, a groove cutting plate, etc. is attached to the reaping section at the front of the machine, and the combine harvester can harvest and thresh grain culms at the same time as, for example, reap and thresh wheat. A device has been proposed in which the seeding machine is used to sow soybeans and the like.

By the way, when the sowing machine is attached to the reaping section at the front of the machine as described above, the reaping status by the reaping section and the sowing status by the sowing machine can be checked at the same time from the operator's seat of the combine, which is very convenient for work. The following problems arise.

That is, when a seeding machine is installed on the front side of the machine, the seeding work is performed by the seeding machine at a position in front of traveling crawlers provided on both sides of the bottom of the machine. There is a risk that the crawler will tread on the sowing track due to the following movement.

In addition, when performing seeding work using the seeding machine,
After dispensing a predetermined amount of seeds from a quantitative dispensing device into the grooves formed by the groove cutting plate and covering the soil, it is necessary to flatten the area where the seeds have been sown. A pressing roller placed behind the cutting board was used to compress the sowing area, but when using such a pressing roller, not only did the mounting structure become complicated, but the number of component parts of the seeding machine also increased. There was a problem that the number of products increased and the cost became high.

The present invention was devised in view of the above-mentioned problems, and its purpose is to form a flat ground surface by cutting off the lug part of the traveling crawler that corresponds to the sowing part of the seeding machine. By compressing the sowing portion evenly, the conventional pressure roller is not necessary, and the configuration is simplified,
This is intended to prevent the traveling crawler from trampling over the sowing area.

Therefore, the present invention is made to use a crawler in place of a pressure roller, and its configuration is such that a crawler having an endless belt with lugs is arranged behind the seeding machine, and the crawler is placed behind the seeding machine. The present invention is characterized in that a flat ground surface is provided at a portion located in the sowing area to suppress the sowing area.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The combine harvester according to the present invention will be explained below with reference to embodiments of the drawings.

The combine shown in the drawing has traveling crawlers 3 each having an endless belt with lugs 2 arranged on both sides of the lower part of the machine body 1, and a threshing section 4 and a driver's seat 5 provided in the upper part of the machine body 1. A reaping section 9 consisting of a weed splitting board 6, a grain culm pulling device 7, a cutting blade 8, etc. is provided at the front, and the reaping section 9 removes grain culms as the machine body 1 travels as the crawler 3 rotates. After harvesting, the harvested grain culm is supplied to the threshing section 4 for threshing.

Further, the reaping section 9 is equipped with a sowing machine 10, and the sowing machine 10 performs reaping and threshing operations at the same time.
Seeds are sown in the area where the grain culms are cut by the cutting section 9.

The seeding machine 10 is composed of a seed tank 12 having a quantitative feeding device 11, a grounding ring 13, a groove cutting plate 14, and a soil covering body 15. At the same time, the grounding ring 13 is rotatably supported behind the cutting blade 8 below the reaping part 9, and the grounding ring 13 and the feeding device 11 are connected via a transmission body 16 such as a spiral wire. The rotation of the grounding wheel 13 as the machine body 1 travels operates the feeding device 11 via the transmission body 16 to feed out the seeds in the seed tank 12 in predetermined amounts. There is.

Further, the groove cutting plate 14 of the seeding machine 10 is supported via a support frame 17 at a rear position of the grounding ring 13, and forms a groove in the soil as the machine body 1 travels. A seed tube 18 extending from the feeding device 11 is opened at the rear of the cutting plate 14,
The seeds fed out from this feeding device 11 are sown in the groove formed by the groove cutting plate 14, and the soil covering body 15 is arranged at the rear position of the groove cutting plate 14. As a result, the groove in which the seeds were sown is covered with soil.

The crawler 3 is arranged at a rear position facing the groove cutting plate 14 of the seed sowing machine 10, and a flat plate is placed on the crawler 3 at a portion corresponding to the sowing part by the sowing machine 10 to suppress the sowing part. This forms a ground plane 19 that provides support.

Specifically, the endless belt 2 in the crawler 3
The groove cutting plate 14 is arranged on the front extension line opposite to the inner side in the width direction of the endless body 2, and a part of the lug 2a provided on the outer periphery of the endless body 2 is cut out on the inner side in the width direction of the endless body 2 to form a flat surface. The seeds are sown at the rear part of the groove cutting plate 14, and the soil covering body 1
The sowing part of the seeds covered with soil in step 5 is placed on the ground surface 1.
9 to suppress it.

In the illustrated embodiment, two sets of sowing machines 10 are attached to the reaping section 9, and the groove cutting plates 14 of each of the sowing machines 10 are
Each of the lugs 2a is arranged to face the inner side of the endless body 2 in the width direction of each crawler 3, and a part of the lug 2a located on the inner side of the endless body 2 in the width direction is cut out to form a ground plane 19, respectively. Two rows are sown by each sowing machine 10, and each sown portion is pressed down by the ground surface 19 of each endless body 2.

Further, the endless body 2 is molded from a material such as rubber, and a core bar 21 is embedded in the center thereof.

The combine harvester of the present invention is constructed as described above.
By running, the grain culm is harvested by the reaping section 9, and this harvested grain culm is conveyed to the threshing section 4 where threshing work is performed.

As the machine body 1 travels, a groove is formed in the grain culm reaping area of the reaping section 9 by the groove cutting plate 14 of the sowing machine 10 provided in the reaping section 9, and a metering feed device 11 is formed in the groove. A predetermined amount of seeds in the seed tank 12 are fed out from the seed tank 12, and the groove in which the seeds are sown is covered with soil covering body 15. After this, the part where the seeds are sown is covered with the ground surface of the crawler 3. It was suppressed by 19.

As explained above, in the combine harvester of this invention,
A flat ground surface is formed at the part of the traveling crawler corresponding to the sowing part by the sowing machine, and the sowing part is flattened by the ground plane, so that the traveling crawler can move the said sowing part as usual. In addition, since the sowing area is suppressed by the contact surface of the crawler, the conventional pressure roller is no longer necessary, and the structure can be simplified and can be provided at low cost. It is.
