Description

[Detailed description of the invention] The present invention is based on a sowing device that is attached to a reaping section that can be freely raised and lowered at the front of the machine, and the seed feed from the sowing device is started and stopped in conjunction with the raising and lowering movement of the reaping section. The present invention relates to a combine harvester with a seeding device constructed in such a manner that

As the above-mentioned known technology, for example, Utility Model Application Publication No. 53-1096
There is a technique disclosed in Japanese Patent No. 46.

In a known method, a sowing device integrally provided with a storage tank is attached to a divider portion that is disposed forward of the cutting blade of the reaping section.

Therefore, when sowing is performed at the same time as combine harvester work, sowing is performed before cutting of the culm by the cutting blade has been completed, so avoid areas where unharvested culms may enter the cutting section and move. It is only possible to install seeders,
Therefore, the sowing width is the distance from the back of a divider to the back of another divider, and there is a problem that row spacing cannot be set freely.

In addition, the sowing machine with a seed storage tank is installed at the rear of the divider, so if the tank capacity is increased, the movement of the culms will be hindered, so the seed can be stored sufficiently while work continues. However, since the tank is attached to the reaping section, there is also the problem that the burden of raising and lowering the reaping section is increased, which is disadvantageous.

Therefore, the present invention allows the sowing operation to be carried out simultaneously while harvesting and transporting the culm, and the sowing width can be freely set without interfering with the reaping and transporting of the culm. To provide a device that can perform efficient work with less seed replenishment work without increasing the burden on the lifting and lowering movement of a reaping part.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of the combine harvester. A threshing section 7 equipped with a foot chain 6, etc. is installed on a machine base 5 supported by a crawler 4, and the front part of the machine in front of the threshing section 7 is equipped with a A reaping section A is installed which is equipped with a grass dividing plate 8, a pulling case 9, a cutting blade 10, a conveyor, etc., and the rear lower part of the machine base 5 is pivoted so that it can rotate around the fulcrum 0 with respect to the crawler 4 side. At the same time, a hydraulic cylinder 11 is interposed between the front part of the machine base 5 and the front side of the crawler 4, and the reaping part A is installed so that it can be raised and lowered by the expansion and contraction operation of the hydraulic cylinder 11. is equipped with a driving section 12, and behind it is installed a paddy tank 14 capable of supplying paddy through a hoisting cylinder 13, and paddy can be discharged into paddy bags from each paddy outlet 15 below the paddy tank 14. It will be installed and configured in the same way as before.

A grain tank 3 capable of storing grain for special use such as wheat, for example, is installed in parallel with the paddy tank 14, and the grain can flow out through a feed hose 16 extending in communication with the lower part of the grain tank 3. be installed and configured.

A sowing machine B is installed on the rear side of the cutting blade 10 at the rear of the reaping section A, and the sowing machine B is equipped with a disc blade 1a that cuts soil
An upper steering device 1 consisting of a small plow 1b and a small plow 1b is placed in front, and a seeding port 2, which is the tip side of the supply hose 16, is arranged immediately behind it, and a pressure roller 17 is mounted on a shaft behind the seeding port 2. A support frame 19 connected to a reaping frame 18 provided diagonally behind the reaping section A is installed to support the sowing device B.

Further, a shutter device 20 is provided in the upper part of the seeding port 2.
The device 20 is constructed using an electromagnetic valve or the like so that it closes in conjunction with the rise of the reaping section A and opens in conjunction with its descent.

In addition, the feeding device of a conventional seeding machine can be adopted for the part of the seeding port 2, and various modifications can be made.

During combine harvester operation, when the reaping section A is lowered and moved forward as shown in Fig. 1, the planted culms are reaped and the threshing section 7 threshes the grain, as in the conventional method, and the soil at the site of the reaping is removed. On the other hand, the disc blade 1a makes a cut, and immediately after that, the small plow 1a performs upward steering, and then the seeds are released from the seeding port 2 and are sown, and further after that, the pressure roller 17 performs pressure and sows the seeds. be able to.

When the machine turns around on the headland side or moves elsewhere, the reaping part A is raised by the hydraulic cylinder 11.
At the same time, the shutter device 20 is activated to automatically stop the release of seeds, and when the machine turns around and starts combining again, the shutter device 20 is activated as the reaping section A descends. The seeds will be fed out.

In this way, the present invention is designed so that the sowing machine is attached to the reaping section which is installed at the front of the machine so that it can be raised and lowered, and the seed dispensing from the sowing machine is started and stopped in conjunction with the raising and lowering movement of the reaping section. In the combine harvester, the seeding machine is located in a space formed below the reaping frame behind the cutting blade, and the grain tank for supplying seeds to the seeding machine is arranged in the upper part of the machine body. This has the following advantages:

B Since the sowing machine is installed in the space formed below the reaping frame behind the cutting blade, even if the position in the width direction of the machine is set freely, it will not affect the reaping transportation route of the grain culms. Therefore, it is possible to simultaneously sow seeds to a desired width while working with a combine harvester.

(b) In contrast to the sowing machine, which is installed at the rear of the cutting blade, the grain tank is installed at the top of the combine machine, so even if the tank capacity is increased, there will be no problem with the movement of the culm or the raising and lowering of the reaping section. By increasing the storage amount, it is possible to perform efficient work with reduced replenishment work.

C. Since the seeds are fed by flowing down from the grain tank installed at the top of the machine, it is possible to accurately and efficiently supply seeds by utilizing a large head.
