BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain discharging device for a working machine such as a combine, a harvester, and a transport vehicle.

[0002]

2. Description of the Related Art There is known a structure in which a grain temporarily stored in a combine harvested by harvesting by a swiveling operation of an operating body by operating an operating body or by expanding and contracting is discharged to a predetermined place. . Then, the shape of the tank located on the side of the fryer is formed on a slope so as not to hit the discharge auger elevating device, and the coupler for energizing the electric motor which is the drive source of the length adjusting means is exposed.

Next, the operation will be described. First, when the driver sits on the seat 48 of the driving unit, depresses the parking brake pedal, turns on the key and activates the engine, and the power output from the engine is transmitted to the rotating parts of the body via the transmission mechanism. It is transmitted. Then, the throttle lever is turned to select the engine at a predetermined rotational speed, and the sub-transmission lever is turned to a desired position to select, for example, the standard, and further operate the threshing lever and the reaping lever. When the threshing unit 9 and the reaping unit 8 are driven, the machine conditions and the like are displayed on the respective indicators on the instrument panel.

When the preparation for the harvesting work is completed, the depressing of the parking brake pedal is released, and then the speed change lever is turned to the side to advance the machine body, and the operating lever is tilted in the front-rear direction to cut the cutting section. The height position of 8 is determined, or the tilting body 13 is adjusted to the predetermined distance while tilting left and right to change the traveling direction of the body. Then, the root portion of the cereal culm caused by the lagging lug 14 that moves obliquely rearward and upward along the raising case is cut by the cutting device 16 and is inherited by the reaping culm conveying device 17 and is conveyed upward and rearward. Is done.

The cereal culm that has reached the transport end is sandwiched by the automatic cereal culm feeding device 18 and conveyed backward, fed into the straw processing device 12 and processed. And sent into the handling room for threshing. Processed products such as grains produced by this are separated into grains and straw chips by wind screening, and the grains are sent into the tank 10 by a transport device such as a spiraling device and a frying device and stored therein. .

Then, when the grains in the tank are full,
The driver interrupts the harvesting operation and moves, for example, the combine near the ridge. When the discharge auger 1 is moved to a predetermined position by manual operation, first, the turning operation body 4
Is tilted to the side (front side) farther from the user, the switch 52
Is turned on, and an excitation signal is output from the CPU 67 to the lifting solenoid 51 via the output interface 69 to excite it. Then, the operation of the solenoid valve 50 causes the discharge air to be discharged.
Since the gas elevating device 39 is extended, the rotation
The case 36 rotates with respect to the fixed case 36 to move the discharge auger 1 upward.

When the discharge auger 1 rises to a predetermined position, the operator returns the turning operation body 4 to the original neutral position and then tilts the switch 56 to the left to turn on the switch 56. Then, the CPU 67 outputs a start signal to the electric motor 2 via the output interface 69 to start the motor, so that the rotational power is transmitted from the frame gear 22 to the hoisting cylinder gear 23 and the hoisting cylinder 21, The connection case 35 and the discharge auger 1 are turned to the left around the longitudinal axis.

When the worker has reached the predetermined position by observing the movement of the discharge auger 1, the operator returns the turning operation body 4 to the original neutral position. Then, the output of the start signal output from the CPU 67 is stopped, and the movement of the discharge auger 1 is also stopped.
When performing the automatic extension, the operator sets the automatic extension switch 62 of the discharge auger operation panel 47 to "ON", and outputs an excitation signal from the CPU 67 to the lifting solenoid 51 via the output interface 69. Excite. Then, since the discharge auger elevating device 39 is extended by the operation of the solenoid valve 50, the rotating case 36 is rotated with respect to the fixed case 36 to move up the discharge auger 1. .

When the CPU 67 which has received the detection signal of the sensor 65 via the input interface 68 determines that the discharge auger 1 has risen to the highest position, the CPU 67 sends the signal to the switch 56 via the output interface 69. "enter"
Output a signal. Then, the electric motor 2 is started, so that the rotational power is transmitted from the frame gear 22 to the frying cylinder gear 23, and the frying cylinder 21, the connection case 35 and the discharge auger 1 are moved in the vertical direction. It turns to the left around the center.

Thereafter, the CPU 67, which has received the detection signal of the sensor 66 via the input interface 68, determines from the output interface 69 that the electric motor has been turned when the discharge auger 1 has turned to a preset position. The output of the start signal to the data 2 is stopped. Next, when the operator tilts the turning operation body 4 to the near side and sets the switch 55 to “ON”,
Since the excitation signal is output from the CPU 67 to the lowering solenoid 54 via the output interface 69 to excite it, the operation of the solenoid valve 53 shortens the discharge auger elevating device 39. -Case 36 is fixed case 3
6 and the discharge auger 1 descends. Then, when the discharge auger 1 descends to the grain discharge position, the operator returns the turning operation body 4 to the original neutral position.

After performing any of the above operations, the operator tilts the length adjusting operation body 5 forward to extend the switch 58.
Is turned on, the CPU 67, which has received this information via the input interface 68, outputs a start signal to the electric motor 3 via the output interface 69 to start the motor screw shaft 45, and Turn forward. Then, the projection 46 moves along the screw portion at the tip of the discharge auger 1 (the discharge side of the grain).

Then, when the discharge port of the discharge auger 1 reaches the predetermined position for storing the grain, the operator returns the length adjusting operation body 5 to the original neutral position, and the CPU 67 outputs the output through the output interface 69. Since the output of the start signal output to the electric motor 3 is stopped, the movement of the discharge auger 1 is also stopped.

Subsequently, when the lower spiral operating body 49 is operated to switch to the transmission state, the rotational power is reduced to the lower spiral, the lifting spiral shaft 25, the transmission mechanism 38, the short spiral shaft 30, and the long spiral shaft 3.
4 to rotate. Therefore, the grains stored in the tank 10 are conveyed in the order of the lower spiral, the helix spiral shaft 25, the short spiral shaft 30, and the long spiral shaft 34, and the tank 10,

Is turned on, the CPU 67, which has received this information via the input interface 68, outputs a start signal to the electric motor 3 via the output interface 69 to start the motor screw shaft 45, and Reverse. Then, the projection 46 moves in the axial direction toward the base side of the discharge auger 1 along the screw portion. At this time, the moving cylinder 29 also moves in the same direction.

Further, in connection with the movement of the movable cylinder 29, a part of the shaft 32 of the long spiral shaft 34 slides on the short spiral shaft 30 and moves in the same direction as the short spiral shaft 30.
Are sequentially moved to the short spiral side with the movement of. When the long spiral shaft 34 reaches the predetermined position, the output of the start signal to the electric motor 3 from the CPU 67 via the output interface 69 is stopped.

Subsequently, when the operator tilts the turning operation body 4 to the right and sets the switch 57 to "ON", the CPU 67 outputs a reverse start signal to the electric motor 2 via the output interface 69. Since it starts, the rotational power is free
The gear 2 is transmitted from the gear 22 to the
1. The connection case 35 and the discharge auger 1 are turned to the right around the longitudinal axis.

Then, the CPU 67, which has input the information output from the sensor 66, outputs the auger 1 to the auger receiver 64.
When it is determined that the motor has reached a predetermined position above the motor, the start output signal to the electric motor 2 is stopped. Then, when the operator tilts the switch 55 to “ON” by moving the switch 55 to the near side, the lowering solenoid 5 is output from the CPU 67 via the output interface 69.
An excitation signal is output to 4 to excite. Then, the solenoid valve 53
The discharge auger lifting / lowering device 39 is shortened by the operation of (1). In connection with this, the rotating case 36 is rotated with respect to the fixed case 36 to lower the discharging auger 1.

The CPU 67, which has received the information stored in the auger receiver 64 by the discharge auger 1 from the sensor 65 via the input interface 68, makes the lowering solenoid 5

Further, in connection with the movement of the moving cylinder 29, a part of the shaft 32 of the long spiral shaft 34 slides on the short spiral shaft 30 to move in the same direction as that of the short spiral shaft 30, and the moving spiral 33 also moves along this shaft 32.
Are sequentially moved to the short spiral side with the movement of. When the long spiral shaft 34 reaches the predetermined position, the output of the start signal to the electric motor 3 from the CPU 67 via the output interface 69 is stopped.

Subsequently, the CPU 67 outputs a start signal for reverse rotation to the electric motor 2 via the output interface 69 to start the motor, so that the rotational power is transmitted from the frame gear 22 to the hoisting cylinder gear 23. Frying cylinder 21, connection case 35
And the discharge auger 1 is rotated rightward about the longitudinal axis. When the CPU 67 determines that the discharge auger 1 has reached the predetermined position above the auger receiver 64, the CPU 67 stops the start output signal to the electric motor 2 and ends the automatic storage operation.

When the grain is discharged, if the discharge port of the discharge auger 1 is farther from the grain discharge position,
If the shortening switch 61 is set to “ON” by tilting the length adjusting operation body 5 to the front side, the same operation as described above is performed and the length is shortened, so that the discharge port can be moved to an appropriate position. When a pile of grains is formed at a certain discharge position, the length of the discharge auger 1 can be expanded or contracted or moved in the horizontal direction while discharging the grains by performing the manual operation. It can be discharged to the entire grain storage section of trucks and trucks.
Even when the combine 6 is moved, the movement frequency can be reduced.

When the discharge auger 1 is stored in the auger receiving side, even if the turning operation body 4 and the length adjusting operation body 5 are tilted in the same way and the switch is turned on, the start command from the CPU 67 is issued. Since the signal has a time difference, the inrush power at the time of starting the electric motors 2 and 3 can be reduced, and the power supply circuit and wiring can be made thin. Further, as described above, since the turning operation body 4 and the length adjusting operation body 5 are provided close to the discharge auger operation panel 47, the turning operation and the expansion / contraction operation of the discharge auger 1 are easy. At the same time, the desired grain can be moved to the discharge position quickly. Since the extension switch 58, the shortening switch 59, and the like are provided between the operation bodies 4 and 5, erroneous operation of the operation of the operation bodies 4 and 5 can be prevented.

Further, during the automatic extension or automatic storage operation of the discharge auger 1, the manual operation of the length adjusting operation body 5 as described above is performed by turning the switches 52 and 55 on and off. Since the extension / contraction work 1 can also be performed, the time for projecting and storing the discharge auger 1 can be shortened, the working efficiency can be improved, and the occurrence of damage or breakage due to the discharge auger 1 hitting an obstacle can be prevented.

If the start of the electric motor 3 is prohibited until the tip of the discharge auger 1 reaches the highest position, the length of the discharge auger 1 is increased during turning. If it changes, the danger of contact with unexpected obstacles can be prevented.
In addition, when the discharge auger 1 is in the auger receiver 64, the electric motor 3 does not start, so that the discharge auger 1 does not expand and contract, and the auger receiver 64 or the discharge auger expansion and contraction mechanism 40 does not extend. Such damage can be prevented.

Then, when the operator tilts the length adjusting operation body 5 to the right and sets the longest switch 60 to “ON”, the CPU that has input the longest information via the input interface 68
Numeral 67 outputs a forward rotation start command signal to the electric motor 3 to move the movable cylinder 29 toward the distal end as described above.
Thereafter, when the moving cylinder 29 reaches the predetermined position and becomes the longest, the output of the start command signal output from the CPU 67 is stopped.

When the operator turns the length adjustment operating body 5 to the left and turns the shortest switch 61 to “ON”, the CPU 6 that has input the longest information via the input interface 68
Reference numeral 7 outputs a reverse start command signal to the electric motor 3 to move the movable cylinder 29 toward the fixed cylinder 28 as described above. Thereafter, when the moving cylinder 29 reaches the predetermined position and becomes the shortest, the output of the start command signal output from the CPU 67 is stopped.

Therefore, the discharge auger 1 can be set at the longest position and the shortest position by the operation of tilting the length adjusting operation body 5 to the left or right, so that the workability of expansion and contraction is improved. The length of the discharge auger 1 can be adjusted and the longest and shortest positions can be set by operating the single length adjusting operation body 5. Also,
At the time of the movement of the discharge auger 1, the CPU 67, which has input the turning information from the sensor 66, determines that the position of the discharge auger 1 to the overhanging side has reached a preset turning position or near the end of the movement. Output interface 69
To output a start command signal for forward rotation to the electric motor 3 via
The extension of the discharge auger 1 is started.

Conversely, when the CPU 67 receives the turning information from the sensor 66 during storage, when the CPU 67 determines that the position of the discharge auger 1 has reached the vicinity of the start of the movement or has reached a preset turning position, the output interface 69. A start command signal for reverse rotation is output to the electric motor 3 via the
Start shortening. Therefore, when the discharge auger 1 is moved, since the length of the discharge auger 1 is short, the swing of the discharge auger 1 can be reduced and the turning can be smoothly performed.

Further, the CPU 67 stores a start-up time of the electric motor 3, and the electric motor 3 is determined by the length of this time.
A continuous or pulsed start command signal is output to the data 2 and 3. That is, when the length of the discharge auger 1 is short, C
Continuous output from PU67 to electric motors 2 and 3
When the length of the gas 1 is long, the CPU 67 outputs a pulse to the electric motors 2 and 3, so that the discharge oil 1
Can be quickly stopped and moved to the target position. .

A portion facing the discharge auger elevating device 39 is formed on the slope along the discharge auger elevating device 39, and a recess is formed so as not to hit the discharge auger 1.
Further, since the concave portion 72 is provided on the outer peripheral surface of the upper tank 10b so as not to come into contact with the sliding body 71 that slides on the outer surface of the fixed cylinder 28, the resin-based lightweight tank 10 having high strength is provided. Can be formed.

Since the electric motor 3 and the coupler 73 for connecting the power supply side and the electric motor side are provided in the space surrounded by the cover 75, it is possible to reduce water bathing during rain or washing. At the same time, it is possible to prevent breakdown or damage due to accumulation of foreign matter such as straw waste. And, the connection case 35 in the vertical direction
Since the electric motor 3 which is a drive source of the length adjusting means is provided at a position overlapping with the discharge auger 1, the discharge auger expansion / contraction mechanism 40 provided above the discharge auger 1 is brought closer to the discharge auger 1. be able to. Therefore, the height of the grain discharging device can be reduced, so that the height of the grain discharging device can be made compact, and the field of view behind the driver can be enhanced.
