Conventionally, in the above-mentioned strawberry harvester, as disclosed in, for example, Japanese Utility Model Application Publication No. 1-118622, a clipper-type strawberry cutting device is disposed on the downstream side of the clamping roller in the straw discharge direction. there were.

[Problem to be solved by the invention]

In the above-mentioned conventional structure, in order to achieve an effective waste cutting action by the waste cutting device, the rotational speed of the holding roller must be set as low as possible, and as a result, the reaping traveling speed This has the disadvantage of lowering work efficiency, and since the ejected waste falls and is released almost directly below, a lot of waste accumulates at the passage of the crawler traveling device, causing the traveling device to slip. There were also problems.

The present invention eliminates the above-mentioned problems, enables efficient reaping work, and allows waste to be discharged to a distant location where it does not adversely affect the running equipment. To provide a straw grass harvester which can effectively prevent harmful effects such as entanglement with a tilling device etc. during plowing work after harvesting when the straw is released into the field.

[Means to solve the problem]

A characteristic feature of the present invention is that in the straw harvester described at the beginning, a cutter is provided in the clamping action portion of the clamping roller to push and cut the clamped waste straw as the roller rotates.

[For production]

The waste that is not pinched by the pinching and conveying device that has been selected by the sorting device is pinched and pulled out by a pair of rotating pinching rollers and discharged as it is outside the machine, but during this pulling action, the pinching action of the rollers After being cut by a cutter installed in the section, it will be discharged outside the machine.

[Effects of the Invention] As a result, since the cutter acts integrally with the clamping roller, a reliable cutting action can be achieved regardless of the rotational speed of the clamping roller, and the clamping roller can be set at high speed. It is possible to perform reaping work efficiently,
In addition, we have been able to obtain a device that can increase the power of discharging debris and scatter it to locations far away from the aircraft.
