Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine culm-removing device, and more particularly, it can be used in a cutter device or the like for shredding threshing-completed culm in threshing of combine.

[0002]

2. Description of the Related Art Conventionally, in a threshing machine mounted on a combine, the threshed culm that has been threshed is taken over from a feed chain that holds and conveys the culms during threshing in the handling barrel chamber of the threshing machine to the culm conveying device. Then, it is sent to a cutter device for culling, is shredded by this cutter device, and is then thrown out of the machine.

A cutter device for shredding culm in such a series of operations comprises a disk-shaped rotary blade having saw teeth formed on the outer circumference, and a disk-shaped feed rotor having substantially triangular projections formed on the outer circumference. Are arranged relative to each other, and the feed rotor forcibly feeds the culm to the rotary blade, and at the same time cuts the culm together with the rotary blade, the rotary blade and the feed rotor are always constant during the shredding process. The work was carried out while maintaining the rotation speed.

[0004]

However, in the case where the rotary blade and the feed rotor always maintain a constant rotation speed, such as the conventional cutter device, when the work is performed, the feeding speed of the feed chain is constant. There is no problem as long as it is, but in the form in which the feed speed of the feed chain is synchronized with the mowing transfer speed, especially in the case where the feed speed of the feed chain changes in accordance with the change of the mowing transfer speed, When the mowing and conveying speed is low, the amount of culm sent from the feed chain to the cutter device is smaller than that of the conventional combine, so it is difficult to uniformly send the culm to the rotary blade by the feed rotor, which is unstable. It becomes a disordered posture and it is not shredded accurately by the rotary blade, the cutting length of the culm is extremely uneven, and in the worst case the culm is not cut and the cutter device Entangled to the rotary blade and the feed rotor,
The combine work may be hindered.

Therefore, according to the present invention, in the combine in which the feed speed of the feed chain is synchronized in accordance with the change in the cutting transfer speed, by further synchronizing the rotation speed of the feed rotor of the cutter device with the transfer speed of the feed chain, It is intended to solve the problem.

[0006]

The present invention relates to a combine thresher in which the feeding speed of the feed chain 1 for feeding and feeding the grain culms to the handling barrel chamber is synchronized with the reaping and feeding speed, and a rear threshing machine is provided with a rotation. A cutter device 4 is provided for arranging the blade 2 and the feed rotor 3 relative to each other to shred the threshed culm, and the rotary blade 2 of the cutter device 4 is kept at a constant rotation speed, and the rotation speed of the feed rotor 3 is changed. The combine culmination system is characterized in that the feed chain 1 is changed in synchronism with the conveying speed of the feed chain 1.

[0007]

With the above construction, when the mowing and conveying speed is low, the conveying speed of the feed chain is also slowed down in synchronization with this, and a small amount of the mowing grain culms are supplied to the handling barrel chamber almost uniformly. The threshing process is carried to send the threshed culm to the cutter device, but the feed rotor of this cutter device also synchronizes with the feed chain and the rotation speed is slow, so it is sent out from the feed chain almost uniformly. The small amount of culm can be uniformly and smoothly transferred to the rotary blade by the rotor whose rotational speed is synchronized with the feed chain, and can be fed to the rotary blade in a stable and normal posture. You can refuse. Further, even when the mowing and conveying speed is high, the feed chain and the feed rotor are synchronized with the high speed side, of course, as opposed to the low speed, so that the appropriate shredding can be performed as in the case of the low speed side. ..

As described above, even if the cutting and conveying speed is changed to high or low, the feed speed of the feed chain is changed to high or low in synchronism with the cutting and conveying speed, and further, the rotation speed of the feed rotor of the cutter device is changed to this feed. Since the height changes depending on the speed of chain transfer, the harvested grain culms are almost uniformly supplied and transferred to the handling chamber by the speed of feed chain transfer, and then the threshed culm discharged from the feed chain. Is almost uniformly fed to the rotary blade by the synchronized rotation speed of the feed rotor, and can be shredded more accurately by the feed rotor and the rotary blade. In particular, when the cutting and conveying speed is low, the rotation speed of the feed rotor is constant as in the conventional case, and when the amount of culm fed to the feed rotor is small, the feeding posture of the culm to the rotary blade by the feed rotor is low. Is unstable and it is difficult to assume a normal posture, and the cutting length of the culm by the rotary blade is extremely uneven, and in the worst case, the culm is not cut and entangled with the rotary blade and the feed rotor, Even if the amount of culm sent to the cutter device increases or decreases, work is not hindered, and the rotation speed of the feed rotor is synchronized with the feeding speed of the feed chain, so that the culm can always be discharged accurately. It can be shredded.

Next, the operation of the above configuration will be described. When the prime mover 8 is started, power is transmitted to the traveling device 11, the mowing device 12, the threshing device 6, and the like. As a result, the napped culms sown by the weeding rod 13 of the reaping device 12 are raised by the raising device 14 and then raked by the rake device 15 and simultaneously reaped and reaped by the cutting blade device 17. The grain culms are transferred to the scraping device 15 and the vertical conveying device 16.

Thereafter, the processed threshed grains are stored in the grain tank 9.

In such a series of threshing operations, the vertical conveying device 16 of the mowing device 12 and the feed chain 1 of the threshing device 6 are synchronized in their conveying speeds by the action of the mowing and transmitting case 24. , The transport culm is the harvesting device 1
2 is smoothly transferred to the threshing device 6 without any unevenness, and the feed chain 1 makes the handling cylinder 19 almost evenly.
Is supplied to.

The threshed culm that has been threshed at the feed chain 1 at the conveying speed is passed from the end of the feed chain 1 to the beginning of the culm-carrying and conveying device 21 at the rear side of the feed chain, and the discharged culm is discharged. It is transported by the culm transporting device 21 and is fed to the cutter device 4 from the end portion thereof.
