Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain storage device for a combine harvester.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION A combine harvester equipped with a grain tank for storing a certain amount of harvested grains and a discharge pipe for discharging the grains in this grain tank to the outside of the machine. Normally, this ejector tube is stored in the storage position when the aircraft is running.

When discharging grains, the direction is changed from the storage position to the appropriate discharging position and the discharging operation is performed, but this discharging takes a considerable amount of time, and the operator waits for this discharging time before discharging. At the end of the process, it is cumbersome as it requires an operation to stop the ejection operation and an operation to return the ejector to the storage position, and since the ejector is a long protrusion from the body, changing the direction is likely to be dangerous.

This invention aims to automate these operations at the end of grain discharge to save labor and prevent danger.

Means for Solving the Problems The present invention provides a grain tank (1) that stores grains with a discharge pipe (2) for discharging grains that can change its direction, and a grain tank that detects grains. A grain sensor (3) is provided, and when the grain sensor (3) detects grain discharge, the discharge position of the discharge tube (2) is operated to the storage position, and the operation of the discharge tube (2) is displayed. A grain storage device for a combine harvester is provided with a signal (4).

Functions and Effects of the Invention When the grains in the grain tank (1) are completely discharged, the grain sensor (3) detects the completion of the discharge and stops the discharge operation of the discharge tube (2), and also stops the discharge. The cylinder (2) is operated from the ejection position to the storage position, and at the same time, the ejection cylinder (2)
A signal (4) is emitted indicating a direction change operation.

Due to this effect, the worker can perform work other than discharging work during the discharging time, and when the discharging is finished, the discharging tube (2) automatically returns to the storage position, so there is no need to perform a stowing operation. In addition, since the signal (4) is emitted during the operation of changing the direction of the discharge tube (2), the operator is alerted and safe.

Embodiment In the illustrated example, there is a pair of left and right traveling devices T61 on the lower side.

On the upper surface of the panel portion 4, there is provided a solenoid valve that is energized to switch between moving the piston 12G in and out and stopping the piston 12G, and a solenoid valve e4 that is energized to switch between moving the piston in and out of the cylinder Qa and stopping the piston. A switching lever (5) that automatically switches the manual lever 4 is provided adjacent to the manual lever 4, and a switching lever (5) that automatically switches the switching lever 4 is provided in a position adjacent to the manual lever 4. In the adjacent position,
A motor switch (21) is provided for intermittent rotation of the motor (13).
When the discharge pipe (2) rotates upward to a certain position, the operation of the hydraulic cylinder (23) is stopped via the solenoid valve Q4, and the piston is closed via the solenoid valve (to). A switch (2) is provided to operate the cylinder +211 in the direction of pushing out the threshing machine (mua), and the ejection tube (
2), when the cylinder C211 rotates and passes, the operation of the cylinder C211 is stopped via the solenoid valve (to), and
The cylinder I via the solenoid valve I1241
A switch (to) that energizes the discharge tube (2) to the side where the discharge tube (2) descends is provided, and a switch (to) is provided on the left end of the upper surface of the control section (9) to engage the discharge tube (2) in response to the downward movement of the discharge tube (2). A U-shaped locking tool 0υ is provided, and when the discharge pipe (2) is fitted into the locking tool Gυ, the solenoid valve Q4
