And a control motor 24 is attached to the end of the receiving rod 22. Further, the sliding frame 20 has a structure in which the rear portion 20a is screwed into the screw rod 23, and when the screw rod 23 is driven, the sliding frame 20 is laterally moved by a spiral. In the case of this configuration, the sliding frame 20 is
When the control motor 24 is driven in the normal direction, the control motor 24 slides outward with respect to the lifting support frame 12, and when it is driven in the reverse direction, the control motor 24 slides toward the storage position A side.

As described above, the sliding frame 20 is supported by the upper sliding ring 21 and the lower angle member 21, and is slid from the storage position A to the left outer side by driving the screw rod 23. There is. The grain culm raising device 25 has a raising lug 26, is inclined so that the starting end portion is located in the lower front and the terminal end portion is located in the upper rear, and is slidably supported by a support cylinder 27 protruding from the transmission case 16.

It is configured by connecting as much as possible. Next, controller 30
Will be described. The inclination sensor 31 is attached to the traveling vehicle body 1 to detect that the vehicle body 1 is inclined, and the result can be input to the controller 30 as data. The control motor 24 is the controller 3
The screw rod 23 is driven to rotate normally or reversely based on the output signal from 0 and is transmitted. in this case,
The controller 30 is configured to drive the control motor 24 in the reverse direction when the inclination of the traveling vehicle body 1 exceeds a preset reference value (inclination α) by the input from the inclination sensor 31. Reference numeral 32 denotes an operation switch, which is manually operated to control the control switch through the controller 30.
The motor 24 can be driven to rotate in the forward direction or the reverse direction.

Another Embodiment The traveling vehicle body 1 includes a steering operation lever 33, as is well known in the art.
Is operated to the left or right, the side clutch device and the side brake device in the traveling mission device (not shown) are operated to make a turn. The turning detection switch 34 is provided at a position where the movement of the steering operation lever 33 is detected, and the detection result is input to the controller 30. And the controller 30 is
When the turning detection switch 34 detects the movement of the steering operation lever 33 and inputs the movement, an output signal for reverse rotation drive is output to the control motor 24.

Next, the operation of the embodiment of the present invention will be described. First, the mowing pretreatment device 5 uses the rotational power transmitted to the transmission case 16 via the telescopic shaft 28,
The harvesting device 3, the grain culm raising device 25, and the grain culm transporting device 4 are driven. Then, when the crawlers 7 and 7'are driven to move the traveling vehicle body 1 forward, the grain culms in the field are weeded by the weeding rods 18 in the front part, and then the grain culm raising device 25 is placed at the start end. It reaches and is caused to be upright.

In the grain culm, the root of the plant is cut by the reaping device 3, held by the grain culm conveying device 4 and conveyed to the rear upper part, and is inherited by the starting end portion of the feed chain 10 of the threshing device 2 and the ears are threshed. It is supplied to the handling room 9 of the device 4. Then, the grain culms are threshed in the handling chamber 9, fall into the sorting chamber 11 below, and are sorted by the combined action of the sorting wind and the swing sorting shelf. The grain thus sorted is stored in the grain tank and filled in the paddy bag.

Now, when the pre-mowing treatment device 5 slides to the left side of the chassis 2 in the traveling direction to mow the grain culm row on the left side, when the operation switch 32 is operated to the forward drive side. , An output signal is sent to the control motor 24 through the controller 30 and is driven in the normal direction. Then
The sliding frame 20 is guided by a screw rod 23 in which a screwed portion of a rear portion 20a is rotating, and is guided while a sliding ring 21 is supported by a receiving rod 22, while a front angle member is provided. 17 is slid in the direction of the arrow shown in FIG. 1 while being guided while being supported by the roller 15.

Therefore, the pre-mowing treatment device 5 slides the reaping device 3 from the storage position A to the left side of the traveling vehicle body 1 as shown in phantom in FIG. It is possible to cut the grain culm in that part. Further, when the cutting pretreatment device 5 is configured to be associated with the direction control device of the traveling vehicle body 1, before the steering of the crawlers 7, 7 ′, first, the cutting device 3 slides and then the shortage occurs. If the crawlers 7 and 7'are controlled in direction, the steering angle of the traveling vehicle body 1 may be small, and the ride comfort of the operator can be prevented from being impaired.

As described above, while the mowing threshing work is continued in the state where the pre-mowing treatment device 5 is slid to the left side in the traveling direction of the chassis 2, the traveling vehicle body 1 moves on the farm field as shown in FIG. If the vehicle is running on a sloped surface or an uneven surface, or if the weight of the vehicle body is tilted due to left-right unbalance due to the grain tank being filled with grains, the inclination sensor-31
Detects the inclination direction and the inclination α. Then, the tilt sensor 31 inputs the detection data to the controller 30. Then, the controller 30 stores reference data in which the input data from the detection sensor 31 is stored.
When the inclination .alpha. Exceeds the reference inclination, the output signal is transmitted to drive the control motor 24 in the reverse direction.

Then, the mowing pretreatment device 7 has the screw rod 23.
Based on the rotation of the vehicle, the vehicle slides in the opposite direction to return to the storage position A within the vehicle width of the chassis 2. Therefore, since the reaping device 3 is slid to the storage position within the width of the vehicle body when the traveling vehicle body 1 is tilted, the reaping device 3 is less likely to collide with an obstacle and a cutting accident can be prevented in advance.

In the above embodiment, the case where the traveling vehicle body 1 leans in the left-right direction has been described, but the traveling vehicle body 1 often leans in the front-back direction during field work or when mounted on a truck. In this case, the excellent effect can be exhibited.
It should be noted that when the combine is mounted on a truck, the reaping device usually performs a storing operation in advance, but this is effective when the operation is forgotten.

Therefore, the pre-mowing treatment device 7 does not have to worry about forgetting to store it and can automatically return to the original position, so that there is no damage and safe work can be performed.

[0022]

As described above, according to the first aspect of the present invention, first, the pre-mowing process has the mowing device 3 and the grain culm conveying device 4 on the front side of the threshing device 2 mounted on the traveling vehicle body 1. The device 5 is provided so as to be able to move up and down, and the mowing device 3 located at a lower position of the mowing pretreatment device 5 is provided so as to be movable laterally outward with respect to the storage position A within the normal vehicle width. ,
Since the harvesting device 3 is configured to be able to return to the storage position A when the traveling vehicle body 1 reaches a predetermined inclination α, it is possible to increase the grain supplied to the grain tank during the harvesting threshing work. If the left-right balance of the traveling vehicle is lost and the traveling vehicle is tilted, the reaping device that has protruded laterally outward slides to the storage position and returns to the inside of the vehicle, which has the effect of preventing damage to the reaping device. .

According to the second aspect of the invention, a pre-mowing treatment device 5 having a mowing device 3 and a grain culm transporting device 4 is supported on the front side of the threshing device 2 mounted on the traveling vehicle body 1 so as to be vertically movable. The reaping device 3 is provided at a lower position of the pre-mowing treatment device 5 so as to be movable laterally outward with respect to the storage position A within the normal vehicle width. When the turning operation 1 is performed, the harvesting device can return to the storage position A. Therefore, when the harvesting device interrupts the work and performs the turning operation, the harvesting device automatically slides back to the storage position of the traveling vehicle body. Therefore, the reaping device has a feature that it can be protected from damage without worrying about forgetting the storing operation, and that it can safely turn at the edge of the field.
