The present invention relates to a processing apparatus.

As described above, there are known combine waste discharger processing devices that can change and adjust the discharge position of the waste discharger from the waste discharger conveying device as described in [1] and [2] below.

JP 2003-47322 A (paragraphs [0017], [0019], FIG. 4, FIG. 12, FIG. 13) JP-A-5-49337 (paragraphs [0013] and [0014], FIG. 1)

As described in [1] above, the structure is such that the expansion and contraction operation of the holding rail of the discharge wall conveying device and the opening and closing operation of the discharge wall inlet of the discharge wall shredding device are performed by an artificial operating force by the operation lever. However, since the amount of expansion and contraction movement of the holding rail with respect to the operation amount of the operation lever is relatively large, the operation amount tends to be relatively heavy because it is necessary to amplify and transmit the operation amount of the operation lever. If the lever length of the operation lever is made sufficiently long, it is effective for lightly performing the operation, but this causes another problem that a large operation space is required for the operation lever.
In addition, in order to transmit the operation of the operation lever to both the holding rail and the opening / closing lid, the holding rail and the opening / closing lid are operated in an operating state in which the operation timing and the operation amount are different from each other. It is necessary to have an operating mechanism that is set up so that various flexibility functions properly, such as the flexibility to absorb and the difference to absorb the difference in the operation amount, and the mechanical structure is likely to be complicated. there were.

  As described in [2] above, the operation result of the electric motor is detected by a detection device such as a potentiometer so that the expansion and contraction of the holding rail and the opening and closing operation of the open / close lid can be performed by the driving force of the electric motor. In the structure in which the operation of the electric motor is controlled, relatively expensive components such as a potentiometer and a microcomputer are required, and it is difficult to reduce the cost.

  The object of the present invention is to make it possible to easily perform the expansion / contraction operation of the holding rail of the discharge wall conveying device and the opening / closing operation of the discharge wall inlet of the discharge wall shredding device using the driving force of the electric motor, and Another object of the present invention is to provide a combine waste transporter conveying device that can simplify the structure and reduce the cost.

When the lid operating manipulator is operated to the open side of the opening / closing lid, the rail operating electric motor contracts and moves the telescopic rail portion of the holding rail to the cutting and discharging position, and the lid opening / closing electric motor opens and closes the opening / closing lid. If the extension operation of the holding rail is instructed by the artificial manipulator for rails when the opening operation is performed and the draining cutter is shredded with the opening / closing lid opened, the rail operating electric motor and the lid opening / closing electric motor are not activated. The operations of the rail operating electric motor and the lid opening / closing electric motor are linked so as to be in a state.
[Operation and effect of invention according to Solution 2]
According to the structure shown by the said solution means 2, the expansion-contraction rail part of a clamping rail can be easily expanded-contracted using the drive force of the electric motor for rail operation. For this reason, there is no need for a large operation lever or the like for moving the telescopic rail part greatly, and it can be operated lightly with a small device.
In addition, the operation command by the electric motor for rail operation is not output from the control device using the microcomputer, but the waste outlet discharge position detected by the limit switch that detects the discharge end position of the telescopic rail portion is visually checked. Based on the display result of the display means for displaying in a possible state, it is performed by a drive command and a stop command by a rail manipulative manipulator that can be manually operated.
Therefore, the detection means for detecting the operation on the side of the sandwiching rail that is expanded and contracted by the rail operating electric motor and the control device for performing the control based on the feedback signal of the detection result are not required. There is an advantage that cost can be easily promoted.
As described above, in the combine drainer processing apparatus of the present invention according to the solution 2, the operations of the rail operating electric motor and the lid opening / closing electric motor are linked to each other, and it is necessary to chop the drainer. When the lid operating manipulator is operated to the opening side of the opening / closing lid, the rail operating electric motor contracts and moves the telescopic rail portion of the holding rail to the cutting / discharging position in accordance with the operation of the opening / closing lid.
In other words, the opening / closing lid can be opened and the telescopic rail can be moved to the cutting / discharging position by simply opening the opening / closing lid with the lid operating manipulator, without requiring any operation with the rail manipulator. Both operations can be performed, and the simplicity of the operation can be achieved.
In addition, while operating the lid operation manipulator to the open side of the open / close lid, the expansion rail part of the holding rail remains in the state of being operated to the long straw discharge position. It is also advantageous in that the shredding work is easily revealed.
And, in the state where the opening straw is shredded with the open / close lid open, the rail operation electric motor and the lid open / close electric motor remain in the non-operating state even if the extension operation of the holding rail is commanded by the rail manipulator. Thus, the waste straw shredded state in which the opening / closing lid is opened is continued.
In other words, when the open / close lid is operated to the closed side in a situation where a large amount of waste straw stays at the waste straw inlet of the waste straw shredding device, the retained waste straw is moved to the back of the waste straw shredding device side. Although it may be easy to cause clogging of the waste water by pushing to the side, such forced operation to the closing side can be suppressed while the lid is open, so that occurrence of clogging of the waste water due to such erroneous operation is avoided. There is an advantage that it is easy. Therefore, even if the artificial manipulator for rails is accidentally touched, it is advantageous in that the opening / closing lid can be prevented from being unexpectedly operated to the closing side.

[Operation and Effect of Solution 5]
As described above, in the combine waste water treatment apparatus according to the present invention according to the solution means 5, the display means for displaying the waste wall discharge position in a visible state is located in the middle of each waste wall discharge position. Since the position of the telescopic rail portion is also displayed, it becomes easy to perform an operation of outputting a stop command to the rail operating electric motor and stopping the telescopic rail portion from extending and contracting after the rail operating electric motor is driven.
In other words, if the display means displays only the discharge waste discharge position, the display state does not change from the discharge discharge position before moving the telescopic rail until the next discharge discharge position is reached. It's hard to tell if it should be stopped. Compared to this, the present invention also displays the position of the telescopic rail part located in the middle of the respective exhaust wall discharge position, so the guideline of the timing to stop the telescopic rail part's telescopic movement is Since it is obtained from the display state of the intermediate position, there is an advantage that it is easy to stop the telescopic rail part more appropriately.

Is displayed on the basis of the detection result, and is configured as shown in FIG.
That is, the display lamp 71 is switched to the first detection switch SW1, the display lamp 72 is switched to the second detection switch SW2, and the display lamp 73 is similarly switched on / off according to whether the third detection switch SW3 is detected. It is configured to be able to.

Therefore, as shown in FIG. 12, in the “shredding position” where the first detection switch SW1 is turned on and the second detection switch SW2 and the third detection switch SW3 are turned off, the display lamps 71 to 73 are Among them, the display lamp 71 is turned on, and the display lamp 72 and the display lamp 73 are turned off.
In the “intermediate discharge position”, the second detection switch SW2 is turned on, the first detection switch SW1 and the third detection switch SW3 are turned off, and among the display lamps 71 to 73, the display lamp 72 is turned on. Thus, the display lamp 71 and the display lamp 73 are turned off.
In the “longest discharge position”, the second detection switch SW2 and the third detection switch SW3 are in the ON state, the first detection switch SW1 is in the OFF state, and the display lamp 72 and the display lamp among the display lamps 71 to 73 are displayed. The lamp 73 is turned on and the display lamp 71 is turned off.

FIG. 12 shows an “intermediate position” between “the shredding position” and “intermediate discharge position” and between the “intermediate discharge position” and “longest discharge position”.
This intermediate position is not directly displayed by the display lamp 71, the display lamp 72, and the display lamp 73. For example, the “intermediate discharge position” between “the shredding position” and “intermediate discharge position” is displayed. At the “intermediate position”, all the display lamps 71, the display lamps 72, and the display lamps 73 are in an OFF state and all are temporarily turned off during the movement of the telescopic rail portion 35. It is indirectly displayed that the part 35 is moving between the intermediate positions.

  In the above example, at the “intermediate position” between the “intermediate discharge position” and the “longest discharge position”, the display lamp 72 is kept on and remains lit, so this intermediate position is displayed. It is not possible. However, for example, a state in which the second detection switch SW2 is temporarily turned off is provided by providing a recess in the exit / exit operation gear 22 at a position corresponding to the region e illustrated by a virtual line in FIGS. 5 and 6. If configured, the display lamp 72 can be temporarily turned off as in the case of the “intermediate position” between the “cutting position” and the “intermediate discharge position” described above. The telescopic rail portion 35 can indirectly display that the intermediate position is moving.

As shown in FIG. 11, the display means 7 is provided with two display lamps 74 and 75 for showing the open / close state of the open / close lid 44.
The display lamps 74 and 75 detect the fourth detection switch SW4 that detects the open position when the fan-shaped transmission gear 27 operates the open / close lid 44 to the open position, and the closed position that operates the open / close lid 44 to the closed position. Based on the detection result of the fifth detection switch SW5, the “open” position and the “closed” position are each displayed.

[Operation circuit]
FIG. 10 shows an operation circuit of the rail operating electric motor 20 and the lid opening / closing electric motor 25. In the figure, the upper terminal is connected to the power source and the lower terminal is connected to the ground. This operation circuit will be described.

First, ignoring the relationship with the lid opening / closing circuit 60 on the side that drives the lid opening / closing electric motor 25, the case where the operation button 5 as the rail artificial operation tool is operated to the expansion side or the contraction side will be described. Then, when the operation button 5 is operated to the “extension” side or the “reduction” side, the rail operation circuit 50 drives the rail operation electric motor 20 to rotate, and drives the exit / retreat operation gear 22 of the rail operation device A. To do.
Accordingly, the first detection switch SW1, the second detection switch SW2, and the third detection switch SW3 that detect the movement of the exit / retreat operation gear 22 are sequentially detected. The detection results of these limit switches 8 are displayed by the display lamp 71, the display lamp 72, and the display lamp 73 shown in FIG.

In the lid opening / closing circuit 60 on the side that drives the lid opening / closing electric motor 25, “pushing” the push button 6 as an artificial operating tool for lid operation, and “open cutting” in which the opening / closing lid 44 opens the insertion port 43 of the cutter case 40. When the switching operation is performed between the position and the “long wall” position in which the opening / closing lid 44 closes the insertion port 43, the lid opening / closing circuit 60 rotationally drives the lid opening / closing electric motor 25 in the forward and reverse directions.
The fact that the lid opening / closing electric motor 25 has been driven to a predetermined position on the forward rotation side is detected by the fourth detection switch SW4 that detects the position of the protrusion 27a of the sector transmission gear 27, and the lid opening / closing electric motor 25 rotates in the reverse direction. The fifth detection switch SW5 that detects the position of the protrusion 27a detects that the drive is performed to a predetermined position on the side. The detection results of these limit switches 9 are displayed by the display lamp 74 and the display lamp 75 shown in FIG.

In the operation circuit described above, the “shredding” position on the side not connected to the lid opening / closing circuit 60 among the two “shredding” positions of the push button 6 as the manipulator for lid operation, and the rail The “reduced” side of the operation button 5 as a human operation tool and the connection portion between the rail operation circuit 50 are connected.
For this reason, when the push button 6 as the manipulator for operating the lid is operated to the “chopping” position, the lid opening / closing circuit 60 rotates the lid opening / closing electric motor 25 to open the opening / closing lid 44. At the same time, the same signal as that on the “reduction” side is also input to the rail operation circuit 50, and the rail operation electric motor 20 is rotationally driven to the reduction side.

When the push button 6 serving as the lid operating manipulator is operated to the “long wall” position, the signal to the rail operation circuit 50 side is cut off, and the lid opening / closing circuit 60 causes the lid opening / closing electric motor 25 to operate. The opening / closing lid 44 is operated to the closed posture by being rotationally driven.
Ignoring the relationship with the lid opening / closing circuit 60, the operation when the operation button 5 as the rail manipulative operation tool is operated to the expansion side or the contraction side is an operation in this state.

And, when the push button 6 as the manipulator for operating the lid is operated to the “chopping” position (the telescopic rail portion 35 of the holding rail 31 is at the most shortened “cutting position”), The rail operation circuit 50 does not output a rotation drive command to the rail operation electric motor 20 even if the operation button 5 as the rail operation tool is operated to the “extension” side or the “reduction” side. It is configured as follows.
That is, even if the operation button 5 is operated to the “reduction” side, the command is the same as the instruction to the “reduction” side from the lid opening / closing circuit 60 that has already been input, and the telescopic rail portion 35 of the holding rail 31. This command is ignored because is in the most shortened “shredding position”.
Further, when the operation button 5 is operated to the “extension” side, the rail operation circuit 50 is in a state where a command to the “reduction” side from the lid opening / closing circuit 60 is input. Yes, a command that is completely opposite to this is simultaneously input. When “extension” and “reduction” are instructed at the same time, the rail operation circuit 50 is configured so as not to output a circuit drive instruction to the rail operation electric motor 20.

  As described above, in the state where the push button 6 as the lid operating manual operation tool is operated to the “chopping” position, the operation button 5 as the rail artificial operating tool is moved to the “extension” side or the “shrinking” side. When the operation button 5 is operated, the notification means (not shown) is linked and actuated, for example, an alarm is sounded whenever the operation button 5 is operated. It is recommended to prompt the user to operate the “long straw” position.
