Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a combine harvester equipped with a device for discharging grain storage bags to the side of the machine body and a device for discharging a group of collected straw to the rear of the machine body, while preventing the grain storage bags from becoming dirty. Regarding technology for releasing into fields.

In a combine harvester, if the grain storage bag is simply released into the field during wet field work, there is a risk that the grain storage bag and the stored grain will be contaminated with muddy soil or muddy water. Therefore, in the past, each time the grain storage bag became full, the machine moved to the edge of the ridge and released the grain storage bag onto the ridge, or the grain storage bag was temporarily placed on a threshing section, etc. When the aircraft moves to the edge of a ridge, the temporarily placed grain storage bag is released onto the ridge. This method is less efficient than the case where bags are released one after another each time they are full.

Therefore, a technology has been proposed in which the timing of releasing waste straw to the rear of the machine and the timing of releasing the grain storage bag are adjusted, and the grain storage bag is dropped and released onto the waste straw released to the rear of the machine (for example, (See Japanese Unexamined Patent Publication No. 52-34242).

According to such conventional technology, it is possible to prevent the discharge bag and the grain from being contaminated by muddy soil or muddy water while adopting a work style in which the grain storage bag is discharged into the field as appropriate.
If you try to move the aircraft backwards, you may step on the grain storage bag, causing it to get dirty or damaged.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and is intended to prevent soiling of the discharge bag and grains by muddy soil and muddy water, and to improve the discharge area of the grain storage bag. The purpose is to allow the aircraft to move backwards if necessary.

The characteristic configuration of the present invention taken to achieve the above object is that, in the above-mentioned thing, a sensor is provided which detects the position of the group of focused waste straw released into the field during the previous process by coming into contact with it. It is provided so as to protrude laterally outward from the machine body, and is also provided with a mechanism that automatically discharges the grain storage bag onto the group of collected waste straw based on the detection operation of this sensor.
This configuration provides the following effects.

That is, according to the present invention, since the grain storage bag is released on top of the waste straw released into the field during harvesting work, even if the work is in a wet field, the Stored grains are less likely to be contaminated by muddy soil or muddy water.

Moreover, since the waste straw that was released to the rear of the machine in the field during the previous process is used as a stain-preventing underlay, there is no risk of the grain storage bag being trampled on and soiled or damaged even if the machine is moved backwards if necessary.

Therefore, according to the present invention, since it is possible to move the machine backward as necessary, the steering operation of the machine accompanying the harvesting work can always be carried out efficiently, and as a whole, the reaping work can be carried out efficiently and economically. It has now been possible to provide a combine harvester that can perform the above operations and also prevent the discharge bag from becoming soiled.
