Description

[Detailed Description of the Invention] The present invention relates to an auger discharge angle regulating device for discharging grain in a tank in a combine harvester with a grain tank.

In this type of combine harvester, when the grain tank becomes full during harvesting operations, the auger is once extended to an upright position, the discharge angle is adjusted, and the grain is transported to a truck on the ridge.

By the way, when the angle of the auger approaches vertical, it is necessary to lift the grain against the entire weight of the grain, and since the grain is conveyed on the helical circumferential surface, a large lifting force is required. At the same time, clogging is likely to occur between the helical circumferential surface and the case tube.

However, conventionally, the grain discharge clutch can be engaged even when the auger is in an upright position, so if grains are discharged in this state, the auger may become clogged or the grains may be damaged.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an auger discharge angle regulating device that is configured such that the helix of the auger cannot rotate unless the auger reaches a predetermined tilt angle, thereby eliminating the aforementioned drawbacks. be.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

As shown in FIGS. 1 and 2, the combine 1 has a frame 3 supported by a crawler 2.
A thresher 5 is loaded at the rear of the frame 3.

Further, a grain tank 6 is disposed on one side of the threshing machine 5, and grains are conveyed from the threshing machine 5 to the tank 6 by a grain lifting cylinder 7.

Further, an engine 8 is mounted on the front portion of one side of the frame 3, and a driver's seat 10 is disposed above the engine 8.

Furthermore, at the rear of the tank 6, there is an auger 10 made of two folds.
are arranged, and the upper auger 10a is provided by a cylinder device 11 so as to be freely raised relative to the lower auger 10b.

Further, a case 12 is fixed to the lower part of the lower auger 10b, as shown in FIGS.
It is rotatably supported.

Further, as shown in FIG. 2, the upper part of the lower auger 10b is supported via a lug 17 at the tip of a cylinder device 16 which is supported by the tank 6 via a bracket 15. Therefore, the auger 10 is Due to the action of the cylinder device 16, the tilting angle θ1. shown in FIG. It can be tilted freely like θ2.

Further, a spiral 18 is provided at the bottom of the tank 6, and power is transmitted to the run 18 from the engine 8 via a belt transmission device 20.

Furthermore, the shaft 18a of the helix 18 protrudes from the tank 6,
Power is transmitted to the helix 22 of the auger 10 via a transmission device 21 inside the case 12.

On the other hand, if the end surface of the wooce 12 on the case cylinder 13 side is
a, and the case cylinder 13 has a cam 12 a.
A switch 23 constituting a sensing body operated by is provided.

Further, as shown in FIG. 5, an operation panel 25 is arranged in the driver's seat 10, and a grain discharge operation lever 26 is guided through a long hole 25a of the panel 25.

The lever 26 is connected via a link 27 and a poaching wire 28 to a tension pulley 30 with which the belt transmission 20 can continue its transmission.

Further, a solenoid 31 constituting a regulating body is provided in the panel 25 adjacent to the elongated hole 25a, and an actuator 31a of the solenoid 31 crosses the elongated hole 25a and can prevent the movement of the lever 26. .

Since the present invention has the above configuration, the combine 1
When the grain tank 6 becomes full during harvesting work in the field, the combine harvester 1 is moved to the edge of the field near the truck on the ridge.

At this position, by contracting the cylinder device 11, the upper auger 10a is raised and the lower auger 10b is raised.
1, and the auger 10 is made to stand upright as a whole as shown by the solid line in FIG.

If in this state, operate the grain discharge operation lever 26.
Even if the actuator 31a of the solenoid 31
5a, and the lever 26 cannot be operated.

Next, by extending the cylinder device 16, the integrated auger 10 and the case 12 are integrated into the case cylinder 1.
3 as the center, the predetermined tilt angle is 0 as shown by the chain line in Figure 1.
When the cam 12a of the case 12 moves once, the switch 2
Activate 3.

As a result, the solenoid 31 is excited, and the actuator 31
Aspirate a.

Furthermore, after tilting the auger 10 to a tilting angle θ2 at which its tip is positioned on the track, the lever 26 is rotated and the belt transmission device 20 is tensioned by the tension pulley 30, thereby transferring the power of the engine 8 to the helical direction. 18 and further via a transmission 21 to the helix 22 of the auger 10.

At this time, the lever 26 is connected to the actuator 31 of the solenoid 31.
Since the part a is retracted from the part a of the long hole 25, the operation is not hindered.

Thereby, the grains in the tank 6 are conveyed by the helix 18 and the auger 10 and discharged onto the truck.

As explained above, according to the present invention, the auger can only eject grains after reaching a predetermined angle for ejecting the grains.
Even if your hand accidentally touches the ejection lever etc. when the auger is not in its proper position, the auger will not be ejected, so the grains will not be accidentally scattered outside the container, and furthermore, the auger will not be in the proper position. Since it is activated after the grain is in a tilted position, the grains can be discharged extremely smoothly, and the grains can be discharged satisfactorily without being damaged.
