Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a structure in which the reaping section at the front of the machine body can be raised and lowered from the ground. This invention relates to a combine harvester that is attached with a structure that protrudes significantly outward compared to a weeding bar, such as a workbench on which a worker rides, which functionally prevents grain entanglement with the running device.

In a combine harvester, in order to reduce the area required for turning the machine in the field, that is, the headland mowing area, the cutting part is temporarily raised when turning at the edge of a ridge, but in this case,
Structures such as the paddy holder and workbench protrude outward from the aircraft, so they may come into contact with the ridges or collide with the ridges when turning, resulting in deformation or damage. There is a good chance that it will come off unexpectedly.

Therefore, it is conceivable to configure the structure so that it can be switched between an active position that protrudes outward and a non-active position that is retracted toward the aircraft, or to configure the structure so that it can move up and down. This not only complicates the supporting structure of the structure and the surrounding equipment such as the threshing device, but also unreasonably increases production costs.In particular, in the case of a paddy holder, it is very troublesome to unload the paddy bag when turning. Time consuming and extra work is required in addition to the work of raising and lowering the reaping station.

In view of this, the present invention attempts to ensure the safety of a structure during turning on a ridge with a simple and inexpensive means by effectively utilizing the raising of the reaping section. be.

Embodiments of the present invention will be described below based on the drawings. The drawing shows a combine harvester to which the present invention is applied, in which 1 indicates three weeding smells la for weeding a three-row shield-standing grain stalk to the left and right.
......, and two pulling devices lb for pulling up two rows of divided grass separately, and 2
The reaping section is constructed by disposing and supporting the cutting blade lc for pulling up and reaping the rows on the frame IA, and this reaping section is arranged at the front end of the machine body equipped with the crawler traveling device 3, and It is configured to move up and down by swinging up and down around a horizontal axis using a drive device such as a hydraulic cylinder.

A is a threshing device mounted on the machine; 8 is a threshing device that holds the base of the standing grain harvested by the reaping section 1, engages the tip of the grain, and transports and supplies it to the threshing device A in a lying down threshing position; A conveyance/feeding device, C, is an operating section surrounded on three sides by a reaping section 1, a threshing device A, and a conveying/feeding device B; A device 2 for discharging and taking out paddy to a position outside the plant is attached to the side of the driving section C in a state that projects greatly outward in order to stably send out a large number of paddy receiving bags 5 discharged from the paddy unloading device D. The rice racks E and E, which are an example of a structure in which the rice grains are attached, are placed close to both sides of the crawler traveling device 3 and rearward from the Karikeito frame IA in order to prevent the grain from getting entangled with the crawler traveling device 3. The extended straw cutter 6 is a scale straw cutter installed at the rear of the threshing device A to cut the threshed grain straw.

In the combine harvester configured as described above, the present invention is such that the lower surface height above the ground (height above the ground) of the protruding rice cradle 2 is equal to the height h above the ground elevation limit of the tip of the reaping section when the machine turns during operation. They are configured to be the same or exactly the same. Note that the rising height h of the tip of the cutting portion is set higher than the virtual ridge height H' determined based on various data. In summary, according to the present invention, when the aircraft turns at the edge of a ridge, the raised reaping section 1 and the protruding structure 2 are located at the same or approximately the same height, so that the raised reaping section 1 preceding the turning By checking the relative positional relationship between the ridge and the ridge, it can be easily determined whether the protruding structure 2 can safely pass through the ridge without colliding with the ridge.

As a result, there is no need to construct the protruding structure 2 in a foldable or elevating type, and the reaping section 1 can be simply raised from the ground.
The safety of the protruding structure 2 when turning on the ridge can be ensured. Therefore, the present invention has been able to provide a combine harvester that can rationally and safely turn the machine at the edge of a ridge and can perform reaping work very efficiently and safely as a whole. be.

Claims (1)

[Claims] 1. In a combine harvester in which the reaping part 1 in the front part of the machine body is configured to be able to rise and fall freely from the ground, and in which a structure 2 that protrudes relatively outwardly is attached to the side part of the machine body, the protruding structure 2 is A combine harvester characterized in that a lower surface ground clearance is configured to be the same or substantially the same as a height above ground rise limit of the tip of the reaping section 1 when the machine turns during work.
