Description

  The present invention relates to a self-removing combine.

For example, in a small self-removing combine harvester that cuts 2 to 3 threads, the cutting width is smaller than the stepping width of the left and right crawler travel devices, so the middle split that cuts and runs on the left and right sides of the machine as uncut ground. Work becomes difficult. Therefore, for example, as shown in Patent Document 1, a cutting portion configured to have a cutting width capable of introducing three crops is configured to be slidable with respect to the traveling machine body, and by a horizontal slide of the cutting portion. There is known one that is configured to be able to perform a swivel operation and a mid-split operation.
JP 10-155339 A

  In this configuration, in normal swiveling work where the horizontal side (left side) of the aircraft is uncut and the other side (right side) is already cut, the cutting part is slid horizontally to the uncut side. Then, two reapings are performed such that the cutting width is projected to the uncut ground side rather than the step width by the crawler traveling device. As a result, the crawler traveling device on the uncut area sinks in the wet field, and the uncut crop is pushed down by the mud that rises laterally, or the mud is raised to the stock of the uncut crop and the next cutting In the process, it is possible to avoid such a problem that the mowing device rushes into the raised mud and accelerates wear. In addition, the middle cutting operation can be performed by introducing the three crops by horizontally sliding the mowing unit to the center of the machine body.

  However, the structure for laterally sliding the cutting part requires a complicated structure for laterally sliding the cutting part that can swing up and down, and a structure for performing the horizontal sliding operation manually or with a driving force. Cost was high.

  In order to be able to perform a split operation without laterally sliding the cutting part, it is necessary to arrange a cutting part having a cutting width close to the step width in front of the traveling machine body. The pulling device to be deployed is overlapped in front of the driving unit, and the cereal carrying device deployed behind the pulling device approaches the driving unit. In this case, since the mowing part swings up and down greatly, there is a possibility that the front part of the cereal conveying device that swings up and down may interfere with the inner part of the body of the driving part. That is, it becomes difficult to arrange the mowing unit in front of the traveling machine body due to the interference between the cereal conveying device that swings up and down and the operation unit.

  As a means for arranging a cutting part with a large cutting width in front of the traveling machine body without causing the front part of the grain conveying apparatus to interfere with the driving part, the cutting part itself is configured to be long in the front, Although it is conceivable to move the unit forward from the driving unit, this not only increases the overall length of the aircraft, but also deteriorates the front-rear weight balance of the entire aircraft.

  The present invention has been made paying attention to such points, and without adopting a structure in which the cutting part is slid laterally, the cutting part is arranged in front of the traveling machine body, so It is an object of the present invention to construct a self-removing combine with a full-cutting specification that can suitably perform work at low cost.

By allowing a part of the operation part side of the cereal transporting device to enter the lower space below the front part of the side operation panel, the cereal transporting device can be arranged at the rear of the machine body. It can be configured to be short before and after the front end is moved backward.

Therefore, according to the first aspect of the present invention, it is possible to suitably perform the cutting operation and the mid-split operation by arranging the cutting unit in front of the traveling machine body without adopting the structure in which the cutting unit is slid horizontally. This is effective in constructing a harvesting type self-detaching combine at low cost.
By shortening the trimming part itself before and after the rear of the aircraft, it is effective in reducing the overall length of the aircraft and maintaining a good balance in the longitudinal weight of the aircraft.
Moreover, according to the said structure, since the supply conveyance apparatus supports and conveys the stock source side and the tip side of a grain straw, it has a bulky structure up and down, and this bulky supply conveyance apparatus is made into a side operation panel. By approaching the driving unit side without interfering with the driving unit, it becomes easy to move the entire cutting unit toward the driving unit side and dispose it in front of the traveling machine body.
