Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a raking device for raking planted culms, a reaping device for reaping raked culms, and a method for transversely feeding and merging the reaped culms to the middle part of the cutting width. The reaping pre-processing section is made up of a pre-processing head section equipped with a merging device for merging, and a feed case equipped with a rear conveyance device for transporting the cut husk inherited from the merging device toward the threshing device. This invention relates to a full-culm input type combine harvester that is attached to a traveling machine via the base end of a feed case so as to be able to swing up and down.

[Prior Art] ゛In the full-culm input type gin pine with the above configuration, if one of the left and right traveling devices falls into the furrow during wheat reaping work, the machine body tilts to the left or right, and the posture of the reaping device changes accordingly. If the reaping device is not placed in a tilted position relative to the ground, there is a risk that one of the left and right ends of the reaping device may sink into the ground. It was configured to be able to control rolling so that the

Particularly, such a rolling control mechanism is indispensable for those having a horizontally long reaping device equipped with the above-mentioned merging device.

[Problem that the invention seeks to solve]

However, in these cases, it is common to use gravity-type tilt sensors as a means of determining the state in which the aircraft is tilted from the horizontal reference plane. If installed in

In other words, if we assume that the gravity sensor uses a weight, etc., the pivot axis of the weight is along the longitudinal direction of the aircraft, but the aircraft does not move in the left-right direction, but rather in the longitudinal direction. Since the weight may be tilted, if the inclination in the front-rear direction is large, the direction of the load applied to the weight changes, and the weight may not operate smoothly.

Therefore, since the weight lacks smoothness, its rocking in the left and right directions also lacks smoothness, and the detection of left and right body inclination is not accurate.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tilt sensor arrangement that is independent of the direction of tilt of the aircraft body.

[Means for Solving the Problems] The characteristic configuration according to the present invention is such that the preprocessing head section is pivotally supported to the feed case so as to be able to be driven in a rolling manner,
The advantage is that it is equipped with a rolling control means that maintains the preprocessing head in a predetermined posture with respect to the horizontal reference line based on the detection results of the gravity-type left and right tilt detection sensor installed in the feed case. is as follows).

[For production]

By limiting the rolling motion relative to the pick and the machine body to the preprocessing head, the preprocessing head can follow even if the machine is tilted from side to side. Subsidence can be avoided. Moreover, since the gravity-type tilt sensor is installed in the feed case, the feed case will tilt in the same way as the aircraft when it tilts left and right, but it will not follow the tilt of the aircraft in the longitudinal direction. Since the preprocessing head moves vertically with respect to the aircraft, there is little change in attitude with respect to the ground, and even if the aircraft tilts in the longitudinal direction, the sensor's operating axis will hardly move in the longitudinal direction of the aircraft. Not tilted.

〔Effect of the invention〕

As a result, the operation of the gravity sensor becomes stable υ,
The accuracy of rolling control can be increased and the cutting height can be set to a desired setting.

A reaping pre-processing section (9) consisting of a feed case (8) containing a feed case (8) is vertically oscillated by a first hydraulic cylinder (6) with respect to the traveling machine αq through the base end of the feed case (8). It is installed so that it can be driven dynamically and forms a large-scale combine harvester that throws all culms.

The outlet (5A) corresponding to the merging device (4) is located at a position eccentric from the width center of the preprocessing head section (5) in plan view, and correspondingly, the merging device (4)
In order to collect the cut culm at the position corresponding to A), it has a spiral feed tooth (4A) that is inclined in opposite left and right directions. A rear conveyance device (
7) is a pair of front and rear transmission shafts @.
