Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine auger auger control device in which a grain tank obtained by cutting and threshing is first filled in a grain tank, and when the grain tank is full, the grain is loaded on the carrier bed of the carrier by the discharge auger. .

[0002]

[Prior art]

 Conventionally, a thresher and a grain tank were installed together on the machine base, and this grain tank was equipped with a discharge auger operated by an undulating drive device and a horizontal swing drive device. We have already proposed a combine grain ejector equipped with an intermittent switch.

[0003]

[Problems to be solved by the device]

 The known combine auger discharge auger controller controls the level of the discharge auger by loading the grain in the grain tank onto the carrier bed of the carrier by an operator other than the combine driver operating the lever to operate the lever. Only the turning direction can be changed, but when the outlet of the discharge auger faces the appropriate height on the carrier bed, the assistant must instruct the driver to move up or down. It was troublesome because it had to be done, and the amount of adjustment was often excessive and insufficient, resulting in low efficiency. Also, when operating the operation lever to change the discharge position of the discharge auger, if you continue to press the operation lever by mistake even after passing the proper position, the discharge auger collides with an obstacle, which causes the operation lever on the other side to collide. There was a danger that the discharge auger would turn in the opposite direction due to turning on and off.

[0004]

[Action]

 When the grain tanks are full of grains due to the mowing threshing work, the driver brings the combine to the side of the vehicle parked on the road and drives the auger manually to raise and lower. Drive the device to raise the discharge auger obliquely upward and rotate horizontally.The drive device horizontally rotates to expose the discharge port to the carrier bed and drive the discharge auger to lift the grains in the grain tank. It is sent and pumped and discharged into the loading platform. When the grain discharge is completed, the discharge auger is stopped, the horizontal turning drive device is used to face the storage position such as on the grain tank or the threshing device, and then the undulation drive device is operated to lay it down. Store in place.

When the height or the left and right position of the discharge auger facing the loading platform is not appropriate, the assistant presses the upper surface portion or the lower surface portion of the sensing switch to turn ON. Then, the undulation drive device operates so that the discharge auger operates on the side opposite to the pressing side, that is, downward or upward, and when the right or left side is pressed to turn it on, the horizontal swing drive device causes the discharge auger to move. Turns to the left or right, and in either case, when the pressure is released, the sensing switch turns off and the corresponding drive stops. Then, if the assistant abnormally operates, for example, the sensing switch is pressed too much or the discharge auger collides with an obstacle, the driving device is stopped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. On a machine base 2 having a traveling device 1, a threshing device 3 is provided on one side, and a cabin 5 in which an operating section is accommodated, a grain tank 6 on the other side. It is equipped with an engine and a pretreatment device 7 consisting of a harvesting device and a grain culm transporting device is installed in the front and back so that it can be moved up and down. It is equipped with levers, measuring instruments and switches.

[0008] At the rear part of the grain tank 6, a lifting spiral cylinder is erected and communicated, and a discharge auger 8 continuously connected to the upper end thereof so as to be capable of undulating and horizontally swiveling is similar to the conventional one. A hoisting drive device consisting of a hydraulic cylinder that expands and contracts by opening and closing an electromagnetic valve, and a horizontal turning drive device consisting of an electric motor 9 and a gear train are attached. When the machine is stored, the discharge auger 8 is attached to the grain tank. It is housed by fitting it into the groove provided on the top plate of No. 6.

On the operation panel of the operating unit, an auger manual lever 10 that can be tilted forward, backward, leftward and rightward is provided as an auger manual operating means, and a raising switch is provided on the left and right of the base of the auger manual lever 10. Auger with S _U , lower switch S _D , front and rear left swivel switch S _L , right swivel switch S _R (the swivel switch may be placed on the left and right, the upper and lower switches on the top and bottom) The switches are turned on and off by tilting the manual lever 10 in the front-back and left-right directions.

Further, an upper switch a, a lower switch b, a right switch c, and a left switch d are attached as sensing switches to the top, bottom, left and right of the tip portion of the discharge auger 8. These switches are shown in FIG. As shown in the figure, it is constructed by partially embedding the contacts S, S on the inner surfaces of the tape material A facing each other in the form of a flat loop made of an elastic material such as rubber. The upper switch a, the lower switch b, and the right switch. c, the left switch d, the up switch S _U , the lowering switch S _D , the left turning switch S _L , the right turning switch S _R , and the operation amount sensor (not shown) are controlled by a control device as shown in FIG. It is connected to the input side of the constituent microcomputer 11, and the calculation results of those input values are used as the solenoid valve solenoid valve of the electric motor 9 of the horizontal swing drive device and the undulation drive device. Is output to the de Sv _1, Sv _2, the microcomputer 11 not a Minara control of the discharge auger 8, the other device as shown in FIG. 5, for example, threshing depth adjustment device, cutting height adjustment equipment, the running direction It is also used for control of control devices. 12 is a light for night work.

Control of the discharge auger 8 will be described with reference to FIG. 6. When the raising switch S _U is turned ON by the auger manual lever 10 to tilt the discharge auger 8 upward, the solenoid Sv ₁ on the raising side of the electromagnetic valve is turned ON. As the hydraulic cylinder extends, the discharge auger 8 tilts upward, and at that time, it continues to tilt upward while the upper switch a is OFF, and the auger manual lever 10 reaches the intermediate position at an appropriate rising angle. Then, when the raising switch S _U is turned OFF, the solenoid Sv ₁ is also turned OFF and the hydraulic cylinder stops, but if this OFF operation is delayed and the tip of the discharge auger 8 hits an obstacle above it, It stops when the switch a is turned on. The same is true when the driver operates down.

When the auger manual lever 10 is turned to the right to turn on the right turn switch S _R , the electric motor 9 is rotated forward and the discharge auger 8 is turned to the right. At that time, when the right turning switch S _R is turned off, the electric motor 9 is stopped and the discharge port of the discharge auger 8 faces the loading platform of the transport vehicle. However, if the right turning switch is left on by mistake, the tip of the discharge auger 8 collides with an obstacle on the right side, the right switch c is turned on, and the electric motor 9 is stopped. The same applies when the auger manual lever 10 is turned to the left.

Furthermore, when setting or changing the grain loading position with respect to the loading platform, a sensing sensor attached to the tip of the discharge auger 8 facing the fixed position of the assistant on the loading platform is used. When any one of the upper part, the lower part, the left side part or the right side part is pushed, for example, when the right switch c is pushed to be turned on, the electric motor 9 operates so as to turn the discharge auger 8 to the left side, When the finger is released from the right switch c at an appropriate position, the electric motor 9 stops. When the left switch d is pressed, the discharge auger 8 turns to the right. Further, if the height of the discharge auger is inappropriate, for example, if it is too low, pushing the lower switch b with a finger to turn it on causes the hydraulic cylinder to rise and the discharge auger 8 to move up to a suitable height. Then, when you release your finger, the power turns off and the hydraulic cylinder stops. When the discharge auger 8 is tilted downward, the upper switch a is pressed. During such operation, if any one of the switches a, b, c, d is accidentally kept pressed and the ejection auger 8 collides with an obstacle, the switch on the operating direction side is turned on and the drive device is stopped. However, it does not return and operate. However, the control by the auger manual operation lever 10 has priority over the control by the sensing switch.

FIG. 8 shows another example of the control of the discharge auger 8. The difference from the above-mentioned embodiment is that when the assistant operates the sensing switch intermittently, the electric motor 9 or the hydraulic pressure is changed. The cylinder is designed so that it will not operate for longer than the time set by the timer, and it is possible to prevent accidents due to erroneous operation or sensor malfunction.
