Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a reaping section rolling device in a combine harvester.

[Prior art]

Conventional devices of this type had a configuration in which the front reaping device automatically rose when the vehicle was moved backwards to prevent collision with stubble in the field, but the rolling of the reaping device If the reaping device has a mechanism and the reaping device is not configured to be parallel to the chassis when it automatically rises, it may roll at a high position or remain tilted.
It was rising.

[Problem that the invention seeks to solve]

The present invention aims to overcome the deficiencies of the prior art.

[Means to solve the problem]

The present invention takes the following technical measures to eliminate the defects of the conventional type. That is, the reaping device 3 can be controlled to roll left and right at the front of the chassis 2 having the traveling device 1,
Moreover, it is installed so that it can be raised and lowered freely, and when the traveling device 1 is switched to reverse travel, the reaping device 3 is raised in conjunction with the operation, and the rolling control of the reaping device 3 is cut off to lower the vehicle chassis. This is a reaping device for a combine harvester configured to return to a state parallel to No. 2.

〔Example〕

First, its configuration will be explained.

The chassis 2 has a traveling device 1, and a reaping device 3 is provided at the front part so as to be able to control rolling.

That is, in the reaping transport frame 4, the base of a support frame 5 containing a transmission device is pivotally connected to the mounting portion 6 of the chassis 2, the tip is connected to a transmission case 7, and the grass cutting body 8,
Culm lifting device 9, reaping device 3, front culm conveying device 10
It is structured using a framework.

The reaping transport frame 4 is configured to be able to be moved up and down by a hydraulic cylinder 11 provided between it and the vehicle chassis.

Note that 12 is a rear culm conveying device.

The reaping conveyance frame 4 is provided with a rolling shaft 13 on one side of the support frame 5 and a rolling cylinder 14 on the other side, so that the front part of the reaping conveyance frame 4 can roll from side to side relative to the transmission case 7.

The horizontal sensor 15 is provided in front of the rolling shaft 13,
The horizontal state of the reaping transport frame 4 is detected and a signal is sent to the control section 20.

The gear shift lever 16 is configured to move the traveling device 1 forward when it is operated to move forward from the vertical position, and to move backward when it is operated to move backward.

17 is a lift switch, 18 is a low link return switch, and when the shift lever 16 is operated to the reverse position,
It is configured to be pushed by a cam 19 and send a signal to the control section 20, respectively.

Note that 21 indicates a rolling solenoid, and 22 indicates a reaping solenoid.

Next, its effect will be explained.

When the shift lever 16 is operated in the forward range to perform work, a signal based on the detection result of the horizontal sensor 15 is sent to the control unit 20, and the rolling solenoid 21 operates the solenoid valve to move the rolling cylinder. 1
Extend and retract 4 to ensure a horizontal position and then continue reaping.

Next, when the gear shift lever 16 is operated to the reverse range, the lift switch 17 and the rolling return switch 18 are turned on one after another, sending a signal to the control unit 20, and the reaping conveyance frame 4 is raised by the action of the hydraulic cylinder 11. Moreover,
The rolling control is cut to return the reaping conveyance frame 4 to the state before the rolling control.

In this way, the vehicle chassis 2 can safely move backward.

〔effect〕

As described above, in this invention, when the gear shift lever is operated to move to the reverse range, the reaping conveyance frame is raised by 2.
Rolling control can be cut and the state before rolling control can be restored.

Therefore, the vehicle platform can be moved backwards safely, and a part of the reaping transport frame does not get caught in the field.
