Description

[Detailed description of the invention] The present invention relates to a riding mobile agricultural machine.

In general, passenger mobile agricultural machines have poor rear visibility, making it extremely difficult to change direction while moving backwards.

Conventionally, this backward movement control device had a technical idea of detecting when the rear end of the aircraft touched an obstacle such as a ridge and immediately stopping the aircraft's backward movement. There was no technical means to go beyond this area and develop technology that controls direction control when reversing.

The present invention basically utilizes the above-mentioned conventional technical idea, but it is an object of the present invention to develop it and provide a riding mobile agricultural machine that can extremely easily change direction while moving backwards using a completely new technical idea. shall be.

That is, the riding mobile agricultural machine of the present invention is provided with sensors 3, 3 for detecting obstacles at the rear end of the body A and near both left and right ends, and when the sensors detect an obstacle, the obstacle is detected. It is characterized in that it is configured to cut off the driving of the traveling device 1 on the sensor 3 side, so that when the aircraft A is moved backward, it will come across an obstacle that serves as a work reference such as an inner ridge between the sensors 3, 3. The sensor 3 on the closer side first comes into contact with a ridge, etc., and the drive of the traveling device 1 on the side corresponding to the sensor 3 on the contact side is cut off. For example, it can be automatically turned until the longitudinal direction of the ridge or the like is substantially perpendicular.

In other words, since this position automatically turns the aircraft A in a direction perpendicular to the reference line such as a ridge at the maximum astern position, furthermore, if this turning end position is set as the next forward direction, When traveling in reverse, the vehicle can change direction without performing any steering operations.

If the configuration is configured so that the turning can be stopped arbitrarily during this turning, it is possible to set an arbitrary forward angle centered on the first sensor 3 that comes in contact with the sensor 3 while looking ahead without looking backwards. It is very easy to change direction while going backwards.

Thus, the present invention as a whole achieves the objects set forth above.

Describing the embodiment of the present invention in detail with reference to the drawings, reference numeral 11 denotes running rollers as a running device provided on the left and right sides of the lower part of a combine harvester body A, which is an example of a riding mobile agricultural machine.

2 is a driver's seat provided near the front side of the aircraft A.

Reference numeral 33 denotes a contact type sensor provided at the lower rear end of the body A and near both left and right ends. (not shown), and the steering clutch (not shown) is operated to the disengaged side by an appropriate mechanism in response to a contact detection signal.

As an actual example, the contact type sensors 3, 3 may be configured to emit electrical signals, and the steering clutch (not shown) may be an electromagnetic clutch.

In addition, contact type sensors 3, 3 can be connected using a link mechanism (not shown).
It may also be configured to mechanically transmit and mechanically switch a steering clutch (not shown).

In either case, if the clutch is not configured so that it can be disengaged at will, there is a risk that the clutch will not engage even when moving forward after going backwards.

Further, the transmission may be configured to maintain the connection between the contact type sensor 33 and the steering clutch (not shown) when the gear is shifted to the reverse side.

To describe an example of the usage state of the present invention configured as described above, in a rectangular field B, the four corners and the vicinity of the short side are defined as the headland a, and the headland a along the short side in the direction (→ mark) in the figure. When you reach the corner of the short side of , continue on this short side (move the aircraft forward a little into the headland a on the long side, and change the forward direction as shown in the figure). When the aircraft A moves backward in the (...>) direction and both contact sensors 3, 3 at the rear end come into contact with the ridge C, the aircraft A turns in a direction perpendicular to the longitudinal direction of the ridge C.

That is, the traveling direction of the aircraft A is approximately parallel to the long side.

After this, move forward in the direction shown in the figure (→ mark) and perform reaping work along the long sides.

By repeating the above operations, the entire field can be harvested and threshed.

In addition, instead of using the ridge as a reference, a sensing bar is provided as a reference near the ridge, and the direction perpendicular to the longitudinal direction of this bar is set as the work progress direction of the machine. It may be configured to be detected by the sensor 33.
