Description

Detailed Description of the Invention] 8 Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a raking device for raking planted grain culms, a reaping device for reaping the raked grain culms, and a harvested grain culm. A pre-processing head unit equipped with a merging device that feeds the culms sideways to the middle of the cutting width and merges them can be attached and detached to a feed case equipped with a rear conveyance device that transports the harvested grain culms inherited from the merging device toward the threshing device. The present invention relates to a leftover feed type feed pin in which a reaping pre-processing section is freely connected and is attached to a traveling machine body through the feed case.

[Conventional technology]

A full-culm input type combine harvester with the above configuration (in this case, when one of the left and right running devices falls into the furrow during wheat cutting work, the machine body tilts to the left and right, and the attitude of the reaping device changes with respect to the ground). In order to avoid this, the reaping pre-processing section is configured to be able to move freely in a rolling manner to prevent the reaping device from moving into a predetermined position. It was configured so that rolling could be controlled to make it a real thing.

Particularly, such a rolling control mechanism is indispensable for a reaping device having a wide cutting width provided with the merging device as described above.

[Problem that the invention seeks to solve]

However, in the case where the pre-reaping processing section is simply connected to the machine body in a free rolling state, the attitude of the pre-reaping processing section is certainly configured to follow the ground. The reaping device is configured to follow the ground by relying on the reaction force from the ground, so if the ground is soft, the reaping device may plunge into the ground in the process of changing its posture in response to changes in the slope of the ground. However, there was the inconvenience of bringing soil into the threshing device.

An object of the present invention is to automatically set the rolling posture of the pre-reaping processing section by using a rolling control means, and to improve work efficiency by selecting a rational installation position of the tilt sensor that constitutes the rolling control means. The point is to provide what we can do well.

[Means to solve the problem]

The characteristic configuration according to the present invention is that the pre-reaping processing section is configured to be able to roll freely with respect to the traveling machine body, and the pre-reaping processing section is set to the absolute reference horizontal line based on the detection result of the gravity type left and right tilt sensor installed in the feed booth. One point is that a rolling control means is provided to maintain a predetermined posture with respect to the roller, and its effects are as follows.

[For production]

That is, the posture of the pre-reaping processing section can be set and maintained at an arbitrary set posture with respect to the absolute reference horizontal plane via the rolling control means based on information from the inclination sensor. Therefore, since the posture is not set by relying on the ground reaction force from the ground, the reaping device will not sink into the ground regardless of the hardness or softness of the ground.

Since the 4@slant sensor as the rolling control means is attached to the feeder case, the pre-harvesting head section may be replaced depending on the crop to be harvested (soybean, rice, wheat, or corn), but in that case, the inclination sensor must also be removed. There's no need.

〔Effect of the invention〕

As a result, it is possible to reduce the chance of failure of the threshing equipment due to the soil brought into the threshing equipment along with the harvested grain culm when the reaping equipment enters the ground, and since the inclined senna is installed in the feed booth, pre-harvesting treatment is possible. There are two methods: a method that reduces work efficiency by requiring the tilt sensor to be replaced, such as when installing it on the head, or a method that increases costs, such as installing a dedicated tilt sensor for each pretreatment head that is to be replaced. There's no need to take it.
