[1] A cam mechanism is driven by an electric motor to operate a reaping clutch, a threshing clutch, and a feed chain clutch, and a shifting operation in the reaping transmission and an operation of the grain unloading clutch of the grain storage device are respectively It is configured to be operated by an actuator different from the cam mechanism or other operation mechanism (see Patent Document 1).
JP 2004-97052 A (paragraphs [0029], [0046], [0047], FIG. 3, FIG. 6, FIG. 12, FIG. 13)

  As shown in Patent Document 1, in a structure in which a cutting mechanism, a threshing clutch, and a feed chain clutch are controlled using a cam mechanism driven by an electric motor, the driving force of the electric motor is used. In addition, it is possible to operate a plurality of clutches lightly, and the operation timing of each clutch can be arbitrarily set by the linkage operation of the cam plate of the cam mechanism and the cam follower, and used in a state suitable for the work form. This is advantageous in that

  However, the operation of changing the cutting speed with respect to the traveling speed during the cutting operation and the operation of discharging the grain stored in the grain storage device to the outside of the machine are operation timings that are unrelated to the operations of the various clutches of the cutting and threshing system. Tend to be done arbitrarily.

  For this reason, conventionally, as shown in Patent Document 1, regardless of a mechanism for operating a threshing clutch or a mowing clutch or an operation tool for the threshing clutch or a mowing clutch, an operation tool or an operating mechanism provided separately can be used. The speed change operation and the on / off operation of the grain carry-out clutch were performed.

  However, as in the above prior art, a mechanism for operating a threshing clutch and a cutting clutch and an operating tool and an operating mechanism that are separate from the operating tool are separately used for cutting and shifting, and for carrying out grains. If configured, it is not preferable because the structure may be complicated and the cost may increase due to an increase in the number of parts.

  However, the operating mechanism for cutting and shifting and the operating mechanism for carrying out the grain are sequentially operated by adopting a cam mechanism or the like using a single operating tool together with a mechanism for operating a threshing clutch or a cutting clutch, for example. With this configuration, as described above, it is impossible to individually operate the operation mechanism for cutting and shifting and the operation mechanism for carrying out the grain irrespective of the operation of the threshing clutch and the cutting clutch. There is a problem in terms of sex.

  It is an object of the present invention to easily and lightly operate a cutting speed change mechanism and a grain carry-out clutch in addition to a clutch cutting control of a cutting and threshing system using an operation mechanism driven by an electric motor. Thus, an object of the present invention is to provide an operating device for a combine which can simplify the structure as much as possible.

[Solution 1]
The technical means taken in the present invention in order to solve the above-mentioned problems are, as described in claim 1, a reaping clutch for turning on and off the driving of the reaping and conveying device, a threshing clutch for turning on and off the threshing device, and a grain. A combine operating device for operating a grain carry-out clutch for turning on and off the drive of the storage device, and a cutting transmission for shifting the driving speed of the cutting and conveying device with respect to the machine traveling speed to a high and low,
The grain includes a first operating mechanism for turning on and off the reaping clutch and the threshing clutch, and a first electric motor for driving the first operating mechanism, and separately from the first operating mechanism and the first electric motor, the grain A second operating mechanism for operating the carry-out clutch and the cutting transmission, and a second electric motor for driving the second operating mechanism,
Each of the operation mechanisms is configured to be capable of changing the rotation direction between the normal rotation direction and the reverse rotation direction by each electric motor.
In the first operation mechanism, the threshing operation position in which the threshing clutch is engaged and the chopping clutch is clutch disengaged from the neutral position where the reaping clutch and the threshing clutch are in the disengaged state, and the threshing clutch, The mowing and threshing operation position is set so that both the mowing clutch and the clutch are engaged,
In the second operation mechanism, a grain unloading position for entering and operating the grain unloading clutch is set in an operation area on the opposite side of the operation area for operating the cutting transmission from the neutral position. And
[Action and effect]
As described above, the combine operating device of the present invention according to the solving means 1 includes a pair of the first electric motor that drives the first operating mechanism and the second electric motor that drives the second operating mechanism. The threshing clutch and the reaping clutch are operated to be turned on and off on the one operating mechanism side, and the operating mechanism and the grain carrying out clutch on the chopping transmission are operated on the second operating mechanism side. Therefore, compared with the case where each of these clutches and operation mechanisms is operated by a separate driving device, the first operation mechanism and the first electric motor, and the second operation mechanism and the second electric motor are combined. Thus, a relatively small number of electric motors and operation mechanisms can be used, and the structure can be simplified in this respect.

  Further, in the present invention according to the solution 1, the operation of the cutting transmission device and the operation of the grain carry-out clutch, which are operated without being directly related to the operation of the cutting clutch and the threshing clutch, are performed. The clutch is operated by a second electric motor and a second operating mechanism which are provided separately from the first operating mechanism and the first electric motor for operating the threshing clutch. For this reason, when operating the harvesting clutch and the threshing clutch, it can be operated without the operation of the harvesting transmission device and the grain carrying out clutch, and conversely, the cutting transmission device and the grain carrying out clutch are operated. In doing so, it can be operated independently without the operation of a mowing clutch or a threshing clutch.

  Therefore, when operating the harvesting clutch and the threshing clutch, there is no need to operate the unnecessary harvesting transmission and the grain carrying out clutch, and conversely, when the cutting transmission and the grain carrying out clutch are operated. It is possible to avoid operating the reaping clutch and the threshing clutch.

  In the operation area of the first operating mechanism, for example, the operation position of the cutting shift is set so that the threshing feed chain and the cutting clutch are turned on after the threshing clutch is engaged, and then the cutting transmission is switched from low speed to high speed. The second operation mechanism may be configured to perform an on / off operation of the grain carry-out clutch. Even if comprised in this way, it is possible to avoid the operation of the above-mentioned useless cutting transmission and the grain carrying-out clutch, or the operation of a useless cutting clutch and the threshing clutch.

  However, with such a configuration, for example, when the cutting clutch or feed chain clutch is turned off from the cutting high-speed running state and the operation such as turning the body is performed, the cutting shift is in the high-speed state. Since the cutting clutch is cut and the feed chain is cut through the operation of switching from the low speed state to the low speed state, the operation until the cutting clutch and the feed chain are cut from the high speed cutting state is inevitably delayed. Tend.

  In contrast, according to the configuration of the present invention, as described above, the threshing clutch and the mowing clutch are operated on and off on the first operating mechanism side, and the operating mechanism and the grain of the mowing transmission on the second operating mechanism side. Since it is configured to operate the carry-out clutch, it is possible to reduce the operation delay as described above by simultaneously performing the operation of the speed change operation system and the operation of the harvesting clutch and the feed chain on each operation mechanism side. This is advantageous in that the operation can be performed in the absence of the operation.

Further, in the present invention according to the solution 1, the high / low speed change operation range of the cutting transmission and the on / off operation range of the grain carry-out clutch can be operated separately in the opposite operation range assigned with the neutral position therebetween. Thus, there is an advantage that the operations can be performed separately while using a common operation mechanism and electric motor.
[Solution 2]
The second solving means of the operating device for a combine according to the present invention is, as described in claim 2, the first operating mechanism includes a threshing clutch in an intermediate operating range between the threshing operation position and the mowing threshing operation position. The feed chain operating position is set such that the feed chain clutch for performing the on / off operation of the feed chain is in the on state and the cutting clutch is in the off state.
[Action and effect]
In the operation device of the combine according to the present invention according to Solution 2 configured as described above, the threshing clutch and the feed chain that performs the on / off operation of the feed chain in the intermediate operation range between the threshing operation position and the mowing threshing operation position. Since the feed chain operation position is set so that the clutch is engaged and the mowing clutch is disengaged, the pillow in a state where the mowing clutch and the feed chain clutch are disengaged to stop the traveling machine body. Can be handled.
[Solution 3]
According to a third solving means of the combine operating device of the present invention, as described in claim 3, the first operating mechanism and the first electric motor are swung laterally outward around the longitudinal axis on the rear side of the machine body. It arrange | positions on an airframe frame within the adjacent space | interval of the grain storage apparatus mounted movably, and a threshing apparatus, and the said 2nd operation mechanism and a 2nd electric motor are on an airframe front side of the said threshing apparatus body. It is characterized in that it is disposed in
[Action and effect]
In the combine operating device of the present invention according to the solving means 3 configured as described above, the first operating mechanism and the first electric motor arranged on the machine frame within the adjacent interval between the grain storage device and the threshing device, Is able to perform maintenance by largely exposing to the outside by swinging the grain storage device mounted so as to be swingable laterally outward around the longitudinal axis of the rear side of the fuselage. The two operation mechanism and the second electric motor are disposed on the body frame on the front side of the body of the threshing device, so that maintenance from the outside is easily performed.

Accordingly, when maintenance is required, there is an advantage that maintenance work from the outside is facilitated by exposing both the operation mechanism and both electric motors to the outside.
[Solution 4]
According to a fourth solving means of the combine operating device of the present invention, as described in claim 4, the second operating mechanism is not operated during the linkage mechanism that links the second operating mechanism and the grain carrying-out clutch. It is characterized in that an operated part is sometimes provided for entering and operating the grain carry-out clutch by human operation.
[Action and effect]
In the combine operating device of the present invention according to the solving means 4 configured as described above, the manual operation is performed when the second operating mechanism is not operated in the linkage mechanism that links the second operating mechanism and the grain carry-out clutch. Therefore, even if the second electric motor that operates the second operating mechanism breaks down, the grain unloading clutch is manually operated. Entering operation, grain in the Glen tank can be taken out.

Hereinafter, an example of an embodiment of the present invention will be described based on the drawings.

As shown in FIGS. 9 to 11, the second system operating device B includes a second electric motor 70b as a driving device 7B that generates the driving force, and the power of the second electric motor 70b as a second operating mechanism. And a second gear mechanism 72B for transmitting to the arm operating mechanism 9 as an attachment, which is fixed to the body frame 1 in a posture substantially parallel to the front wall of the threshing device 4 on the front side of the threshing device 4 Mounted on the plate 18.

  The microcomputer has a second potentiometer 73b as a detection mechanism for detecting the operating state of the arm operating mechanism 9 driven by the second electric motor 70b, and a microcomputer which will be described later as means for controlling the operation of the second electric motor 70b. The control device 100 is configured by providing a second motor control circuit 102 provided as a control program.

  When the operation signals of the various operation buttons B0, B4, and B5 provided on the control panel 11C are input to the control device 100, the second electric motor 70b receives a control command based on the operation signals of the control device 100. Output from the second motor control circuit 102, the second electric motor 70b is driven in the forward direction or the reverse direction. The driving force of the second electric motor 70b is output as the rotational power of the output gear 74b attached to the motor output shaft 71b. The output gear 74b and the gear portion 75b formed on a part of the outer periphery of the partial arcuate plate 91 of the arm operating mechanism 9 described later constitute the second gear mechanism 72B.

  The arm operation mechanism 9 includes an arm operation shaft 90, a partial arc-shaped plate 91 that is mounted so as to rotate integrally with the arm operation shaft 90, and a relative rotation with respect to the arm operation shaft 90. The first operating arm 93 and the second operating arm 94 are pivotally attached.

  One end side of the arm operation shaft 90 is pivotally supported by the mounting plate 18 fixed to the body frame 1, and the other end side pivots with respect to the gate-shaped support plate member 19 fixed to the mounting plate 18. It is supported and mounted in a state where both ends are supported. A second potentiometer 73b is attached to the end of the arm operating shaft 90. As a result, the driving state of the arm operation mechanism 9 by the output gear 74b is detected by the second potentiometer 73b provided at the shaft end of the arm operation shaft 90, and a feedback signal based on the detection result is transmitted to the control device 100. It is comprised so that.

  The partial arc-shaped plate 91 has an operation pin 92 projecting from a support piece portion that extends to the opposite side of the arc-shaped portion where the gear portion 75 is formed. The first and second operation arms 93 and 94 are configured to swing in accordance with forward and reverse rotation of the partial arcuate plate 91 driven by the output gear 74b.

  The first operating arm 93 includes a boss portion 93a that fits externally with respect to the arm operating shaft 90, and is extended toward the radially outer side that is pivotally supported by the arm operating shaft 90 and is mutually opposite. One of the arm portions 93b is connected to an operation wire 15a for the shift operation means of the cutting transmission 15, and a concave receiving surface 93c is formed on the other arm portion 93b to contact the operation pin 92. It is.

  The second operating arm 94 includes a boss portion 94a that fits externally with respect to the arm operating shaft 90, and is extended outwardly in the radial direction that is pivotally supported by the arm operating shaft 90 and opposite to each other. One of the arm portions 94b is connected with an operation wire 50a for turning on and off the grain carrying-out clutch 50, and the other arm portion 94b is in contact with the operation pin 92. Is formed.

  Therefore, as the partial arcuate plate 91 driven by the output gear 74b rotates in the forward direction (counterclockwise in FIG. 9), the operation pin 92 contacts the concave receiving surface 93c of the first operation arm 93. Then, the first operating arm 93 is pressed to rotate counterclockwise, and the operating wire 15a connected to the arm portion 93b on the other end side is pulled to switch the cutting transmission 15 to the high speed side. Manipulate.

  On the contrary, as the partial arcuate plate 91 driven by the output gear 74b rotates in the reverse direction (clockwise in FIG. 9), the operation pin 92 contacts the recessed receiving surface 94c of the second operation arm 94. The second operation arm 94 is pressed so as to rotate clockwise, and the operation wire 50a connected to the arm portion 94b on the other end side is pulled to switch the grain carrying-out clutch 50 to the entry side. Manipulate.

  At this time, since the shifting operation means of the cutting transmission device 15 is biased toward the cutting low speed side on the side of the cutting transmission device 15, the operation wire 15a connected to the first operation arm 93 is always moved to the cutting low speed side. That is, the first operating arm 93 is connected in a state of being urged by an elastic urging means (not shown) so as to rotate counterclockwise.

  Further, since the grain unloading clutch 50 is biased toward the clutch disengagement side on the grain unloading clutch 50 side, the operation wire 50a connected to the second operation arm 94 is always directed to the clutch disengaging side. The second operating arm 94 is connected in a state of being biased by elastic biasing means (not shown) so as to rotate clockwise.

  Therefore, the switching operation to the high speed side of the first operating arm 93 that is rotated by the partial arcuate plate 91 driven by the power of the second electric motor 70b, and the grain carry-out clutch by the second operating arm 94. 50 to the clutch engagement side is performed against the urging force of the elastic urging means on the harvesting transmission device 15 side and the grain carrying-out clutch 50 side. Switching operation to the side and operation to the clutch disengagement side of the grain carry-out clutch 50 by the second operation arm 94 are performed by applying elastic urging means on the cutting transmission device 15 side and the grain carry-out clutch 50 side. Performed by power.

  Reference numeral 19 a shown in FIGS. 9 and 10 is a stopper fixed to the support plate member 19 fixed to the mounting plate 18, and the first and second operating arms 93 and 94 are pulled by the operating pin 92. This is for restricting movement in the direction opposite to the operation direction. That is, when one of the first and second operation arms 93 and 94 is pulled to the entry side, the other operation arm 93 (or 94) that has not been pulled by the operation pin 92 is in the same direction. If it is rotated in the swiveling state, the operation wire 15a or 50a may be loosened and bent with the swiveling, but by restricting the swiveling by the stopper 19a configured as described above, There is no such trouble.

It is configured so that it can be inserted and manipulated artificially into the clutch engagement side.

  That is, an arm portion 94b opposite to the side on which the recessed receiving surface 94c of the second operation arm 94 is formed, and a connection pin 94d for connecting the operation wire 50a are provided, and the operation wire 50a is configured to be detachable from the connecting pin 94d.

  Accordingly, when the arm operating shaft 90 cannot be driven due to, for example, the failure of the second electric motor 70b or the electric system, the operating wire 50a is removed from the connecting pin 94d and hooked to the distal end side as indicated by a virtual line. Using the operating rod 95 provided with the portion 95a, a hook-shaped portion as the operated portion 96 is hooked on the distal end side of the operating wire 50a, and the grip portion 95b of the operating rod 95 is gripped from the lateral side of the body. By performing the pulling operation, the operation wire 50a is manually pulled in the same direction as the second operation arm 94 is rotated clockwise in FIG. 9, and the grain carrying-out clutch 50 is switched to the on state. be able to.

When the operating rod 95 is not in use, as shown in FIG. 3, the operating rod 95 restricts the rise of hot air from the left lateral side of the driving unit 6 to the upper side, and is in the middle of conveyance from the cutting and conveying device 3 to the threshing device 4. The falling straw scraps can be stored on the upper side of the shielding guide plate 28 which is provided so as to be inclined to flow down to the lateral side of the machine body. That is, the hook portion 95a and the grip portion 95b of the operating rod 95 are engaged and supported in the locking holes 29a and 29b formed in the rising rib 29 of the shielding guide plate 28.
