Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine grain discharging and operating device capable of safely discharging grains in a grain tank to a padded bag or the like by means of a discharge auger cylinder.

[0002]

2. Description of the Related Art Conventionally, when a grain is discharged from a grain tank, the discharge auger cylinder is rotated to align a tip discharge port of the discharge auger cylinder with a paddy bag or a tank for storing paddy bags. It is known that an operator located on the side of the paddy performs an on / off operation of the drive section with an operation switch at hand.

[0003]

However, when the paddy bag or the tank is full, the operator may not be able to turn off the operation switch, or it may be full. If it was overlooked, there was a problem that the grain would overflow.

[0004]

The present invention has been devised so as to solve such a problem and to perform a safe and reliable discharge work of the grain. Therefore, the discharge auger cylinder communicating with the grain tank is provided. In a combine equipped with a discharge part driving operation tool in the vicinity of a downward discharge port provided at the tip, a sensor for detecting the full amount of grains is provided at the discharge port, and a clutch on / off member is provided. It is provided, and the operation tool and the sensor are connected to the clutch on / off member.

[0005]

[Operation] Therefore, the discharge auger cylinder is rotated, the tip end of the discharge auger cylinder is aligned with the paddy bag or the paddy bag storage tank on the shore side, and the operator located on the paddy bag side operates the operation tool at hand. However, the grain discharging operation can be easily performed, and when the paddy bag or the tank is full,
Since the sensor can detect and automatically stop the discharging work, safe and reliable discharging work of the grains can be performed so that the grains do not overflow from the paddy bag or the tank.

EXAMPLE FIG. 2 is a side view of the combine, in which a mowing section A and a threshing section B are provided in front of and behind the body supported by both crawlers 11, and a control column 12 and a driving section are provided on the side of the mowing section A. A driving section C equipped with a seat 6 and a side column 13 is provided, an engine section D and a Glen tank 1 are provided behind the driving section C, and a vertical auger communicating with a discharge conveyor 14 in the lower portion of the Glen tank 1 is provided. On the upper part of the cylinder 15, the base of the discharge auger cylinder 2 having the downward discharge port 3 at the tip and having the auger 2a installed therein is rotatably and continuously connected, and the engine portion D to the belt pulley 16 and the gear A spiral body that is provided so as to be able to transmit from the discharge conveyor 14 to the auger 2a via a box 17 and a belt pulley 18 and that can be normally and reversely rotated by a motor 7 in the side column 13. A clutch lever 10 capable of operating a tension clutch pulley 19 of the belt pulley 16 is disengageably engaged with the spiral body 8 so that the clutch lever 10 is engaged and disengaged. When tilted to the above state, both limit switches 9a and 9b for stopping the motor 7 come into contact with each other.

On the shore, there is provided a paddy receiving device E in which a tank 21 capable of supplying grains to a paddy bag 20 below is erected above, and the discharge auger tube 2 is shown in phantom in FIG. 1 to rotate the discharge port 3 as shown in FIGS.
Is set in the upper opening 21a of the tank 21 so as to discharge the grain. The motor 7 can be turned on and off on the tip surface of the discharge auger tube 2 above the discharge port 3. Equipped with a toggle switch type operation switch 4. A sensor switch 5 (for example, a non-contact type equipped with an ultrasonic transmitter / receiver) that can turn off the motor 7 when a grain comes close to the outer peripheral portion of the discharge port 3 is provided. As shown in FIG. 6, the operation switch 4, the sensor switch 5, and both limit switches 9 a and 9 b are connected to the motor 7 via the controller 22.

Further, on the outer surface of the Glen tank 1, there are two circular openings 2 in which a flexible cylindrical bag 23 is continuously provided.
4 is formed, and locking metal fittings 26 for mounting a paddle receiving rod 25 that supports the paddy bag 20 are attached to both sides of the draining pad 4.
A foldable paddy receiving table 27 is provided on the outer lower part of the discharge tube 28 which can be detachably fitted into the opening 24 and has a discharge port 28a on the lower inner end side. The auger 29 is extended, and a motor 30 for driving the auger 29 and a gear case 31 are provided on one end side of the discharge cylinder 28. Normally, the paddy stand 27 is folded. Both openings 24 are closed by the cylindrical bag 23, and the grain tank 1 to the paddy bag 20 are closed.
When hulling is directly carried out on the motor, as shown in FIG. 8, the hull receiving stand 27 is opened, the hull receiving rod 25 is attached to the locking metal fitting 26, and the discharge tube 28 is fitted into the opening 24 so that the motor can be removed. When the auger 29 is rotated by 30, the grains in the grain tank 1 are taken into the discharge cylinder 28 by the auger 29 and are thrown into the paddy bag 20 through the discharge port 28a.

Therefore, as shown in FIGS. 1 and 5, the discharge auger cylinder 2 is rotated to the shore side so that the tip discharge port 3 of the discharge auger cylinder 2 is opened in the opening 21a of the tank 21 or directly in the paddy bag. The operator who looks into the opening and operates the paddy receiving device E operates the operation switch 4 at hand, and the operator of the operating section C operates the clutch lever 10 to enable the on / off operation of the grain discharge. When the tank 21 or the paddy bag is full, the sensor switch 5 detects and the motor 7 is started.
The spiral body 8 can move the clutch lever 10 in the direction of arrow A to turn off the tension clutch pulley 19 to automatically stop the discharging work, so that the grain does not overflow from the tank 21 or the paddy bag. It is possible to perform safe and reliable grain discharge work. Further, since the operation tool 4 is in a toggle state (so-called staircase switch type), the operator has the advantage that the clutch on / off state can be easily reversed by reversing the switch to the current position.

[0010]

As described above, according to the present invention, by rotating the discharge auger cylinder 2, the tip side discharge port 3 of the discharge auger cylinder 2 is provided at the opening of the tank for storing the paddy bag or the paddy bag on the shore side. The operator on the shore side can accurately perform the grain discharging operation while operating the operating tool 4 at hand, and when the paddy bag or the tank is full, the grain is automatically discharged. Since the work can be stopped, the grain can be discharged safely and surely so that the grain does not overflow from the paddy bag or the tank, and the feature is that it can be suitably performed.
