Description

[Detailed Description of the Invention] [Industrial field of application] The present invention discharges the grains in the grain tank mounted on the machine to the outside of the machine via a vertical feed screw conveyor and a horizontal feed screw conveyor capable of undulating and swiveling drive. The present invention relates to a combine equipped with a grain export device.

[Conventional technology]

Conventionally, in the above combine, for example, JP-A-63-92537
As shown in Japanese Patent Publication, an operation switch for driving the conveyor is installed in the vicinity of the discharge port of a horizontal feed screw conveyor that can drive swivel and undulation, and one worker carries out the grain to the bed of a carrier or the like. When performing the work, the operator can freely move the grain discharge port to a desired position while performing the leveling work of the grain on the platform without going back and forth between the platform and the combine driver's seat. By doing so, there has been a configuration in which one worker can easily carry out the grain carrying-out work.

[Problems to be solved by the device]

However, according to the above configuration, when one worker carries out the grain carrying-out work on the loading platform, for example, when an unexpected situation occurs such that the operation of disengaging the traveling clutch is imperfect and the combine suddenly starts moving, There was no means for a person to quickly collect the above situation on the cargo bed, and the consideration for the safety of the above work was insufficient.

An object of the present invention is to provide a combine by which one worker can easily and safely carry out a grain transfer operation.

[Means for solving the problem]

The present invention is characterized in that a first operation tool for operating a drive mechanism for changing a posture of the conveyor and a second operation tool for stopping operation of an airframe-mounted engine are attached in the vicinity of a discharge port of the horizontal feed screw conveyor. I am trying.

[Action]

When configured as described above, for example, when the worker carries out the work of discharging the grain from the grain tank to the bed of the truck,
By operating the first operating tool and the second operating tool by the operator on the bed of the truck, it is possible to change the posture of the lateral feed screw conveyor and stop the engine at any time.

[Effect of device]

Therefore, it is possible to prevent the deterioration of the situation by allowing the operator to carry out the grain while working on the bed, and stop the engine on the bed when a problem occurs on the combine body side. Therefore, by an independent worker,
It has become possible to carry out grain export work efficiently and safely.

Then, a part of the input power is supplied to the rotary shaft (49) of the cross flow fan (12), and another part of the input power is increased or decreased via the gear transmission mechanism (43).
The speed is changed in steps and the feed chain drive sprocket (19
It is adapted to be transmitted to the spindle (46) of a). The gear speed change mechanism (43) shifts the shift sleeve (23) splined to the support shaft (46) to the left and right, so that the high speed gear (24) and the low speed gear (25) loosely fitted to the support shaft (46). The shift fork (22) for operating the shift sleeve (23) is operated by a double-acting electromagnetic solenoid (20). It is supposed to be done. This electromagnetic solenoid (20) is a gear shift mechanism when a sensor appropriately detects that a shift lever (not shown) for operating the hydrostatic stepless transmission (16) is in a forward high speed range higher than a setting. (43) is switched to high speed, and when it is detected that the vehicle is in the forward low speed range below the setting, the gear speed change mechanism (43) is switched to low speed, and the conveyor device (9) and the feed chain (9) are driven in synchronization with the vehicle speed. It is configured to automatically reduce the speed difference with 19).

The grain carrying-out device (4) is a vertical feed screw conveyor (28) for vertically lifting the grain fed by a horizontal feed screw (32) provided at the bottom of the grain tank (5).
And a horizontal feed screw conveyor (26) connected to the upper part of the horizontal feed screw conveyor so as to be capable of undulating and rotating.

And each of them is connected to the control device (41) on the main body side.

The cross control lever (37) selectively opens and closes a set of contacts of a four-contact switch by an up / down switching operation, and thereby the electromagnetic control valve (4) for the hydraulic cylinder (31).
