Description

DETAILED DESCRIPTION OF THE INVENTION This Jlj IITJ relates to a shutter control device for a hopper in a compactor, a harvester, etc., and in particular, it is used to automatically fill and collapse paddy from a hopper into a paddy bag, and to transport the full bag to the bottom of the popper. The present invention relates to a shutter control device for a homper suitable for use in a combine harvester equipped with a hook, which is an automatic paddy filling device that sends out paddy from the space to the floor.

Generally speaking, the larger the capacity of a hopper device in a combine harvester, etc., the longer the continuous working time and the higher the work efficiency. However, usually, the capacity of the hopper is determined by its discharge capacity. The number of paddy bags that can be attached to the outlet is limited by the number of paddy bags that can be attached to the outlet 1-1.In order to increase the paddy storage capacity at one time, including the amount of paddy that can be packed into the paddy bags attached to the outlet 1-1, it is necessary to increase the number of outlet ports. On the other hand, 4 at the combine
Since the space in the brim is limited, it is not possible to increase the number of discharge ports unnecessarily, and if they are installed in multiple rows on the inside and outside of the machine, it will be easier to attach empty bags to the discharge ports on the inside of the machine and to load full bags. Retrieval work became very troublesome. In addition, it is possible to increase the hopper capacity regardless of the number of installed bags.According to this hopper device, the shutter closing operation of the first discharge port part can be performed by the paddy sensor, but the subsequent shutter closing operation can be performed by the paddy sensor. The operation could not be performed with a simple paddy sensor and required a large number of very expensive sensors.

In particular, when a company is equipped with an automatic paddy filling device, it is not possible to increase the number of hopper discharge ports, and the paddy bagging work and the sending out of full bags must be carried out extremely efficiently. In order to function properly, it is necessary to increase the hopper capacity so that a large amount of paddy can be stuffed at once.

The present invention was developed in view of the above circumstances, and although it has an extremely simple structure, it enables a predetermined amount of paddy to be placed into a paddy bag many times from a large-capacity hopper, thereby significantly improving work efficiency. It is an object of the present invention to provide an improved hopper shutter control device.

A feature of the present invention is that the paddy sensor disposed at the hopper discharge port and a timer that starts counting a predetermined time from the detection of the open position of the shutter are connected to the shutter opening/closing driving means. The hopper's nyasotar control device is configured to drive the shutter opening/closing drive means to close the shutter when the timer issues a signal that a predetermined time has elapsed while the hopper is detecting the presence of paddy.

The metal fitting 57 is made of iron B57a on a disk such as four washers, and is sewn into the bag 7 with a cloth 59 such as vinyl interposed therebetween and the same cloth 59 as the bag 7.

As shown in FIG. 9, the outlet 10 of the hopper 5 is slightly offset from the center of the hanger par 6 due to the flow of paddy inside the hopper, but the metal fitting 57 is located at the center of the paddy bag 7.
That is, it is located at the center (L/2) Iζ of the hanger par 6.

Next, the operation of this embodiment having the above-described configuration will be explained.

Magnet bracket 29 and arm 30 of paddy bag feeding device 9
is waiting at position A in FIG. From this state, press the star f button 512 of the first light loading device (see Figure 1).
When is pressed, the start command pulse SP is output from the start button 512 to the microprocessor 71 as shown in FIG. The level 1n indicates the automatic control state). The microprocessor 71 immediately instructs the transport motor 22 to move the support 27, and the transport motor 22 moves as shown in FIG.
As shown in FIG. 7, the support is rotated in the normal direction and moved from A to B in FIG. 7 via the chain 26. At this time, the arm 30 is in an open state as shown by the chain line by the case cam surface 21a. Note that depending on the position of the support 27, a potentiometer S connected to the conveyance motor 22 that drives the support 27
The determination can be made by the microprocessor 71 periodically detecting the output XI (1IH[) of FIG. 19 of FIG.

In this way, when the support 27 reaches the position opening which is the paddy bag storage position, the magnet 29a of the bracket 29 comes into contact with the metal fitting 55 of the paddy bag 7, and the paddy bag 7 is finished in one piece! The reversing switch 55. S6 is activated. Reversing switch S5. When S6 is actuated together, the switch SS, S6, as shown in FIG. 19 [dl: ζ
The pulse signal X2 is output, and the microprocessor 71 thereby reverses the transport motor 22 to move the support 27 in the direction from row to row, as shown in FIG. 1jl. As a result, only one paddy bag 7 is conveyed forward based on the attraction of the magnet 29a, and in the middle of the conveyance, the arm 30 is moved to the cam surface 2.
1a, the paddy bag 7 is switched to the clamping position by the magnet 29a.
It is reliably conveyed to the position C by the adsorption by the arm 30 and the backing by the arm 30.

At this time, the other end of the paddy bag 7 is temporarily fixed by a bag stopper 36 made of a flexible body or the like, as shown in FIG. 5, so that the paddy bag 7 is stretched diagonally.

Potentiometer (7 to (ε) x1 supports 2
When it is determined that the device 7 has reached position C, the microprocessor 71 moves the Un bag device driving momo 41 in FIG.
Each gear 40a~ is rotated in the downward direction as shown in the figure.
The arms 42, 43 are synchronously rotated downward via 40d and 40e, and the magnet 47 surfaces of the pair of adsorption devices 45 collide with the metal fittings 57 on both sides of the rice bag 7 which is in a stretched state. .

When the arms 42 and 43 are lowered and the signal x3 of the lower limit switch 510 is turned ON as shown in FIG. The solenoid 61 is turned ON as shown in FIG. ON
Based on this, the microblower set 71 rotates the motor 22 in the forward direction as shown in FIG. . When it is determined from the output X1 of the potentiometer S7 that the support 27 has reached position 2, the microprocessor 71 reverses the bag opening device drive motor 41 to move the arms 42, 43 to the upper limit switch S9. The signal X4 rotates from the OFF state to the ON state as shown in FIG. 19 (tel). As a result, the metal fittings 57 sewn on both sides of the paddy bag are attracted to the magnets 47 of the suction device 45, and the empty bag 7 is opened.At the same time, the hem of the paddy bag 7 is loosened by moving the suction device 45 to one side. be removed. When the signal x4 of this upper limit switch S9 turns ON, the first
As shown in FIG. 9 fi+, the bag stopper solenoid 61 is turned OFF, the bag stopper 36 returns to a state where it can engage with the paddy bag 7 again, and the support 27 (the next paddy bag 7 due to ζ
Prepare for removal.

Note that due to the attraction of the metal fitting 57 of the magnet 47, the actuator 51 enters against the return spring 52, and the first
Four open bag detection switches S shown in Figure 8 are connected in series.
ll is turned ON as shown in Figure 19 (gl), but
If there is a problem with the previous series of operations, for example, if there are paddy bags in one row but there are no paddy bags in other rows,
If any of the following occurs, such as a mistake in separating the paddy bag, a mistake in transporting the paddy bag, or a mistake in opening the paddy bag, the metal fitting 57 of the paddy bag 7 will not be suctioned by any of the suction devices 45, so the switch S11 One of them remains in the OFF state, and the microprocessor 71 is in the ON state (g x
5 is not entered. Then, the microprocessor 71
detects an abnormality in the opened paddy bag fLQ of the paddy bag 7, and drives the alarm rungo 72 and alarm buzzer 73 shown in FIG. 18 to notify the operator of the abnormality. Furthermore, when the empty bag 7 is not present between the two magnets 47 during the bag opening operation using the suction device 45, the opposing staggered magnets 47 are repelled by the same poles, and therefore the magnets 47
The arms 42 and 43 can be easily rotated upward without being attracted to each other and placing an excessive load on the bag opening device driving motor 4.

Then, the shutter 11 closes and the closed position detection switch S
3 is in the ON state (Fig. 19 0111, all I
When the li bag detection switch Sll is ON, that is, when the two rows of paddy bags are opened without any trouble (Fig. 21 (a)), a small amount of paddy m accumulates in the popper 5, and the output from the paddy sensor Sl is detected. When the signal turns ON (Fig. 21 (bl, (al)
As shown in FIG.
6 is driven until it is in the ON state, the automatic shutter 11 is lowered, and the hopper discharge 1'' 10 is opened to supply the paddy m to the paddy bag 7 (FIG. 21(d)).

At this time, a predetermined amount of paddy m is thrown into the open paddy bag 7 at once, so as shown in FIG. Even if the support arm 70 is on the left side in the figure, the paddy will fall and be thrown in with force.
T with heavy weight! 'It is corrected to the normal paddy input position on the right side of the support arm 70, and the subsequent input of paddy m and the movable paddy receiver can smoothly carry out the full bags from the space A) by the floor 62. Figure 21(d)).

Simultaneously with the supply of paddy, the paddy bag dispensing device 9 driven by the -f'-tonoyatter 11 moves upward as shown by the chain line in FIG. in the state where the magnet bra 1 soto 29 and the arm 30 do not interfere with the paddy bag 7, the conveyance motor 22 is moved to the first
As shown in FIG. 9(J), the bracket 29 and the arm 30 are rotated in the normal rotation direction, thereby moving the bracket 29 and the arm 30 backward to the standby position. On the other hand, when the paddy bag 7 is opened by the suction device 45, it is in a slightly lifted state, and when the paddy bag 7 becomes heavy due to the supply of paddy to the paddy bag 7, the paddy bag 7 is lifted up by the nail light. 7 is removed from the suction device 45 (as shown in FIG. 21 (61, and at this time, the switch Sll is in the OFF state on the axis of FIG. 19)). Furthermore, even if the paddy bag 7 is removed from the opened state by the suction device 45, the automatic shutter 11 is lowered and positioned inside the paddy bag 7, so filling of paddy can be continued without any problem, and the paddy bag 7 can be loaded. /': It becomes full with fXl, overflows to the discharge port 10, and the paddy sensor S1 turns on again (Fig. 21 (f))
. Then, this time, the shutter 11 opens and the image shown in FIG.
Since the close position detection switch S2 is in the ON state as shown in it, the auto shutter opening/closing motor 20 is driven to the upward side and the auto shutter 11 is closed (23rd
Figure 1al).

At the same time as the chassis 11 is raised, the feeding device 9
is lowered, and the magnet bracket 29 and arm 30 are returned to the initial standby position A.

FIG. 22 shows the outputs and driving conditions of each sensor and motor during the process of transporting the paddy bag 7 from the storage position opening, opening the bag, and inserting the paddy. In the figure, "1" indicates an ON state of a switch or motor, and "o" indicates an OFF state. Furthermore, sample times 1, 2, and 19 are the sample times in FIG.

■・・・Compatible with [phase].

In this way, the first paddy bag 7 is full of paddy and the shutter 1
Even when the hopper 1 is closed, paddy continues to be charged and stored in the hopper 5, but as shown in Fig. 21 (1), the hopper
When the full sensor 75 installed on the upper part of the hopper 5 detects paddy m, the microprocessor 71 drives the alarm lamp 72, alarm buzzer 73, etc. to indicate that the hopper 5 is full.
Inform the worker of this. Therefore, the operator stops the combine harvester 1 and stops further reaping and threshing. Next, the operator gets off the driver's seat 2 and operates the hydraulic operating lever 76 shown in FIG. Then, the 23rd
As shown in FIG. 1al, the floor feeding solenoid valve 77 shown in FIG. 18 is turned on and driven, the hydraulic circuit is switched by the valve 77, and the drive cylinder 65 is driven as shown in FIG. 17. The floor 62 of the movable paddy receiver is moved in the direction of the arrow together with the full paddy bag 7 (FIG. 21(X)). Mobile paddy receiver is on floor 62
When the bracket 62a protrudes in the D direction and the auxiliary rice tray moves to the floor 64, the bracket 62a comes into contact with the switch 67.
The output signal x7 is ON as shown in FIG.
In this state, the driving of the valve 77 is stopped as shown in FIG.

In this state, the worker lowers the full paddy bag 7 on the floor 62 onto the field, but the movable paddy receiver uses the back support arm 70 that rises in the E direction as the floor 62 moves in the D direction. As a result, the paddy bag 7 is reliably moved in the D direction, and the paddy receiver is moved together with the floor 62. Therefore, the worker can smoothly take out the paddy bag from the auxiliary paddy receiver on the floor 64 and release it to the field. . In this way, the movable paddy receiver is placed on the floor 62.
When the upper full paddy bag 7 is released into the field, the bag detection sensor 69, which had previously detected the presence of the paddy bag 7 on the floor 62 of the movable paddy receiver and the movable paddy receiver on the floor 62, switches to a light emitting part. 69a
The state in which the light 79 from the paddy bag 7 was blocked has changed to the state in which the light 79 reaches the light receiving part 69b, and the output signal x8 of the sensor 69 is as shown in FIG.
As shown, the state changes from the OFF state to the ON state. In response to this, the microprocessor 71 turns the floor storage solenoid valve 80 from the OFF state to the ON state as shown in FIG. The receiver moves the floor 62 from its previously protruding state in the inward direction until the bracket 62b abuts the switch 66. When the bracket 62b contacts the switch 66, the switch 6
As shown in FIG. 23 1al, the movable paddy receiver changes from the OFF state in which the floor 62 protrudes in the D direction to the ON state, and the movable paddy receiver is positioned at a predetermined position suitable for putting the next paddy into a new paddy bag. Signal x9 is ON
When the state is reached, the microprocessor 71 controls the valve 80,
Therefore, the drive of the drive cylinder 65 is stopped, and the movable paddy receiver stops the floor 62 (FIG. 21 (kl)).

Note that the movement of the movable paddy receiver in the incoming direction of the floor 62 can be carried out manually by the operator by operating the hydraulic control lever 76, without relying on the bag detection sensor 69 as in this embodiment. Of course it is also possible.

Therefore, the worker presses the start button 312 again,
The microprocessor 71 is commanded to put paddy into a new paddy bag 7 from the hopper 5. Then, the support 27 moves according to the time chart shown in FIG. 19, and as in the case described above, the paddy bag 7 is pulled out from the storage position opening on the left side of FIG. 7, and the bag is opened by the automatic bag opening device 37. , shutter 1
The opening timing of No. 1 is as shown in Fig. 19 [
The motor 20 was driven as shown in FIG. Therefore, when the open bag detection switch Sll is turned on and the rice bag 7 is opened and set below the discharge port 10, it is immediately opened and filling of rice from the hopper 5 is started. Then, as shown in FIG. 24, the motor 2o is driven, the shutter 11 is opened, and the open position detection switch Is2 is opened.
When turned on, the microprocessor 7 immediately commands the timer 82 to start at 31 o'clock for 1 second, and when 1 second has elapsed and a suitable amount of paddy has been put into the paddy bag 7,
The shutter 11 is closed by driving the motor 20 in the opposite direction. (See Fig. 21), in +) In this way, at the first point when a predetermined amount of paddy is put into the paddy bag 7, the operator operates the hydraulic operating lever 76 in the same way as in the previous case, and the movable paddy receiver is moved to the floor position. 2 along with the paddy bag 7 in the I3 direction, the full paddy bag 7 is released into the field, and the start button 312 is pressed again to enter the next feeding cycle. After repeating this cycle several times, there will be no paddy in hopper 5 (Fig. 21 ip
+ As shown in FIG. 24, when the paddy sensor S1 changes from the ON state to the OFF state where it does not detect paddy,
Regardless of the elapsed time of I seconds, Fig. 21 (ql
As shown in , the shutter 11 is immediately closed to complete the closing operation. Then, the operator presses the start button S], 2 again, returns to the driver's seat 2 after setting a new paddy bag, and resumes operation of the combine harvester 1.

As explained above, according to the present invention, in a state where the paddy sensor S1 detects the presence of paddy m, the shutter 11 is activated when the predetermined time of the timer 82, which is started by the operation of the shutter open position detection means S2, elapses. Since it closes automatically, it is possible to put a predetermined amount of paddy into the paddy bag 7 many times from the discharge port 10 of the hopper 5, even though it has an extremely simple configuration consisting of a single paddy sensor S1, and therefore, it is possible to charge a large amount of paddy into the paddy bag 7 many times. A large capacity hopper 5 can be used with a small number of discharge ports 10, and the work efficiency can be greatly improved.

In particular, when applied to a combine harvester 1 equipped with an automatic filling device, the automatic filling device enables efficient bagging work.
It is possible to significantly improve efficiency.
