Description

[Detailed Description of the Invention] 8 Detailed Description of the Invention [Field of Industrial Application] The present invention is a full-culm input type in which the entire length of the harvested culm is thrown into the handling chamber for threshing, and a type in which only the tip side is placed in the handling chamber. This is a self-contained combine harvester that inputs and threshes grain, and is capable of maintaining a constant reaping posture despite directional inclination, and is configured so that the reaping pretreatment device can be rolled in the left-right direction of the machine with respect to the traveling machine. , relates to a combine harvester that can maintain a constant reaping posture despite the horizontal inclination of the machine body.

[Conventional technology]

In this type of combine harvester, conventionally, when performing the rolling operation of the reaping pretreatment device, the reaping fXlirrJAt
It was common to configure the mechanical equipment to be in a free rolling state so that it always follows the ground.

[Problem that the invention seeks to solve]

When adopting the above configuration, the reaping pre-treatment device can only be set to follow the ground, which limits the reaping posture, and when the field surface is soft, the ground reaction force is small. There is also the problem that the reaping device rushes into the screen.

The purpose of the present invention is to diversify the rolling control (automatic/assisted switching is possible), and also to enable the corresponding reaping pretreatment device to change the reaping posture to any desired position, and to allow the reaping device to move into the field. The point is to provide something that can prevent intrusion.

[Means for solving problems]

The characteristic configuration according to the present invention includes a self-help mode in which the pre-reaping treatment device is controlled to be maintained at a set horizontal tilt angle with respect to an absolute horizontal plane, or controlled to be maintained at a set horizontal tilt angle with respect to the ground, and an optional self-help mode. The present invention is characterized by comprising a mode switching means capable of switching between a manual mode in which the ground attitude of the reaping pretreatment device can be switched and set, and a holding mode in which the reaping pretreatment device is maintained in a constant attitude with respect to the machine body, Its effects are as follows.

[For production]

That is, by providing an actuator capable of rolling drive to the pre-reaping treatment device, the attitude of the pre-reaping treatment device can be arbitrarily changed based on the signal from the sensor.
Therefore, when performing rolling drive control, it is possible to use a gravity-type inclination sensor and control the left-right inclination of the reaping pre-processing device based on the detection result so that it is at a set angle with respect to the absolute horizontal reference plane, or Ground distance sensors are provided at the left and right ends of the reaping pre-processing device, and based on the detection results of these sensors, the left and right inclination of the reaping pre-processing device can be controlled to be at a set angle with respect to the ground. It is also possible to construct an automatic mode in which the posture of the reaping pretreatment device can be automatically controlled using an actuator.

In addition, in addition to the automatic mode described above, a manual mode is provided in which the ground posture of the reaping pretreatment device can be changed based on the driver's visual judgment, and it is possible to switch between the two. Effectively used when equipment breaks down.

In addition, in the holding mode, the attitude of the pre-reaping treatment device relative to the machine body can be maintained constant based on the detection result of the attitude detection sensor, so that the pre-reaping treatment device can maintain a constant attitude with respect to the machine body, for example, when carrying the machine at the edge of a ridge or when driving on the road. When raising and retracting the machine to a non-working position, it is possible to prevent the reaping pre-treatment device from falling naturally and changing its tilted position due to hydraulic leakage in the hydraulic actuator control system.

〔Effect of the invention〕

As a result, the working position of the reaping pre-processing device can be set to any position regardless of whether it is automatic or manual, and unlike conventional methods, the working position of the reaping device can be set to any position depending on the ground reaction force from the field surface. It is possible to take a posture suitable for the conditions of the cutting ground while preventing the grain from falling into the surface, and the cutting height of the grain culm can be adjusted to the desired height. Since changes in the attitude of the processing device are suppressed, stable running conditions such as prevention of overturning when going over ridges can be achieved.

This holding mode is particularly effective, for example, when the pre-reaping treatment section (9) is raised and turned at the edge of a ridge, since there is no change in the posture of the pre-reaping treatment section (9).
