Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention is provided with a mowing unit which is located in front of a threshing device equipped on a traveling machine body, and the mowing section is provided on one side of the traveling machine body. It is configured to be laterally movable with respect to the traveling machine body in a first state in which the traveling machine body protrudes greatly and a second state in which the traveling machine body is located closer to the front than the first state. The present invention relates to a harvesting method using a combine equipped with a crawl traveling device on the traveling machine body.

[Conventional technology]

When using a combine to carry out a round-cutting operation with the uncut grain culm on the left side of the machine body, the mud pushed out by the crawler traveling device on the uncut side pushes down the uncut grain culm, or the mud is present at the plant origin. When swelling, when cutting this uncut grain culm, the reaping device swells and rushes into the mud to accelerate wear, or a large amount of mud is attached to the root of the cut grain culm and is deposited on the transportation route, In order to solve the problems such as the above, it is considered that the cutting unit is projected to the left side with respect to the machine body and the left crawler traveling device is separated from the uncut grain culm, and when the cutting work is started in the field. When cutting and cutting in the cutting area, the cutting unit is set to be located almost in front of the machine so that the right crawler traveling device can be used properly so that the uncut rice culm is not stepped down. Configured Than it is.

Conventionally, in the combine as described above, the harvesting work has been performed by switching without considering the traveling conditions in the field, the positional relationship with the uncut grain culms, and the stump.

[Problems to be Solved by the Invention]

By the way, in the field at the time of the above-mentioned mowing work, in general, it is often a soft wet field with a lot of water,
Since there is a tendency for the machine body to sink or the traveling device to slip, there is a problem in that forward traveling is hindered and reaping work becomes difficult.

INDUSTRIAL APPLICABILITY The present invention makes effective use of the stubs after cutting, which are usually planted at regular intervals (about 30 cm), and rationalizes the relative arrangement relationship between the cutting unit and the crawler traveling device of the fuselage. Therefore, it is possible to appropriately perform a traveling state in which the propulsion force is increased by preventing the sinking and slipping of the airframe and a traveling state in which the crawler traveling device more effectively prevents the mud from gathering on the uncut grain culms. The purpose is to

[Means for Solving the Problems]

The combine harvesting work method according to the present invention is provided with a harvesting unit located in front of the threshing device equipped on the traveling machine body,
With respect to the traveling machine body, the reaping unit is arranged in a first state in which the reaping section largely projects laterally to the traveling machine body and in a second state in which the traveling machine body is located closer to the front side than the first state. In the harvesting work method by a combine, which is configured to be laterally movable to the left and right and has a pair of left and right crawler traveling devices in the traveling machine body, in the first state, the grain to be harvested located next to the uncut grain culm. It is set such that the uncut rice end of the crawler traveling device is located beside the already cut stub of the stump of the culm, and in the second state, it is located next to the uncut culm. It is characterized in that the crawler traveling device of uncut rice is set so as to ride on the stump of the grain stalk to be cut, and the work is performed.

The operation and effect of this characteristic configuration are as follows.

[Work]

That is, in order to prevent the muddy soil from rising to the uncut grain culm, when the cutting operation is performed by projecting the cutting unit largely to the one lateral side, the uncut grain culm and the uncut side crawler traveling device Since there is a stump of the crop culm to be cut,
It is possible to prevent mud gathering by the crawler traveling device by the stump. Further, when performing the mowing operation in the second state, the crawler traveling device for the uncut mower can be positioned while riding on the stump of the grain crop for uncut mower, so the sinking of the machine can be prevented. Suppression or slip can be suppressed, and the propulsive force of the aircraft can be improved.

〔The invention's effect〕

Therefore, according to the present invention, the first state and the second state are selected as the relative positional relationship between the crawler traveling device and the mowing unit, and the uncut grass grain to be mowed and the crawler are selected. By setting the relative position with the traveling device as described above and performing mowing traveling, it is possible to more reliably suppress mowing traveling and pushing down of the mud on the uncut grain culm, and there is a risk of sinking. At least in wetlands, etc., by carrying out the mowing work while riding on the stump of the grain stalks to be cut next to the uncut grain stalks, it is possible to suppress the sinking of the aircraft or to prevent slippage, which is a driving force. As a result, the running performance can be improved and the workability is improved.
