Description

[Detailed explanation of the idea] The present invention relates to a waste culm processing device.

Conventionally, this type of desk-type cutter was used to reliably feed and shred the culm.

A blade attached to both parallel shafts has been proposed, but desk-type cutters are configured so that one shaft rotates at a low speed and the other shaft rotates at a high speed. The blade edges periodically come into contact with each other.

As a result, a large amount of culm, especially on the root side where there is a large amount of culm, is pinched between opposing blade plates, resulting in frequent accidents that damage the blade or distort the shaft. .

The present invention aims to eliminate the drawbacks of the conventional method through a simple yet rational configuration, to enable reliable feeding and shredding of waste culms, and to improve waste culm processing efficiency.

To explain the details of the embodiment with reference to the drawings, A is the combine main body, B is the reaping device, C is the threshing device, D is the traveling body, and E is the
is a desk-type cutter installed above the rear of the threshing device C.

The desk-type cutter E includes a cutter case 1 and a low-speed rotating shaft 2 parallel to and parallel to the cutter case 1.
and a high-speed rotating shaft 3, a rotating circular blade 4 provided at appropriate intervals on the low-speed rotating shaft 2 and having a culm scraping action, and a rotating circular blade 5 provided on the high-speed rotating shaft and corresponding to the rotating circular blade 4. It is composed of etc.

6 in the figure is the outlet of the shredding culm installed in the cutter case 1;
7 is a screw conveyor provided below the cutter mechanism.

The present invention provides a desk-type cutter E as described above.
As shown in FIGS. 2 and 3, a blade 8 consisting of a plurality of blades is fixed to two parts of the low-speed rotating shaft on the tip side and the root side, or on the bottom side, and a blade 8 consisting of a plurality of blades is fixed to the corresponding three parts of the high-speed rotating shaft. A hollow feed roll 9 made of an elastic material such as rubber is provided.

The feed roll 9 is attached to the flange of a bobbin 10 that is rotatably loosely fitted to the high-speed rotating shaft 3, and rotates due to friction with the high-speed rotating shaft 3 when the culm does not intervene, but it rotates due to friction with the high-speed rotating shaft 3. When the exhaust culm intervenes in between, the rotation is prevented by the squeezing force, and the rotation can follow 80 revolutions of the blade, thereby increasing the accuracy of the feeding efficiency of the exhaust culm.

As shown in FIGS. 6 and 7, the screw conveyor 7
The lower cylindrical portion 11 of the cutter case 1 corresponding to the cutter case 1 is formed to become larger toward the direction of the discharge port 6 to cope with the increase in the amount of cut culm on the tip side, and to smoothly release the cut culm. It's like it's going to happen.

Next, the operation will be explained. The harvested and threshed culm is sent from the delivery end of the threshing device C to the desk-type cutter E by the action of the culm conveyor 12 and the conveyor rail 130.

The waste culm transported into the cutter case 1 is scraped in by the scraping action of the rotary circular blade 4 provided on the low-speed rotating shaft 2, but the root and tip of the waste culm, which tend to be delayed, are fed in by the blades 8. By the action of the blades 8 and the corresponding feed rolls 9, the blades are forcibly fed between the two rotary circular blades 4 and 5, ensuring reliable shredding.

In particular, even if a large portion on the root side is fed all at once, since the feed roll 9 is made of an elastic material, the feed roll 9 will be shaped by that amount, further increasing the clamping force and ensuring feeding. let

As described above, according to the present invention, the culm is fed into the cutter case by the action of the blade provided on one shaft and the elastic feed roll provided on the other shaft and made to correspond to the blade. Even if a large amount of culm intervenes, it can be controlled by the deformation effect due to the elasticity of the feed roll and the action of rotating to follow the rotation of the blade, which is different from conventional methods. It has great practical effects, such as being able to prevent damage and distortion of wings and shafts with a simple configuration.
