2. Description of the Related Art Conventionally, a combine has a construction in which a sliding type mowing device which can perform mowing while sliding a mowing device mounted on a front portion of a traveling vehicle body in a lateral direction with respect to the vehicle body. ing. The combine having the sliding type mowing device can effectively cut the culm at the ridge, so that the area of the pillow mowing performed by hand mowing can be reduced, and the crawler jumps. The mowing device can be slid significantly outward from the car body to cut and run, so that the mud to be raised does not splash on the planting stalk row adjacent to the cutting width, so that cutting can be easily performed in the next process. There are advantages such as being able to.

[0003]

In this type of combine, since the pre-cutting device slides right and left, it is necessary to balance the weight balance in the front-rear direction and the right-and-left direction during and after the slide to perform a stable cutting slide. Required for. For this purpose, the mowing pre-processing device, which is slidably mounted on the front part of the traveling vehicle body, distributes the gears equally to the left and right in addition to the left and right distribution of weight to secure the right and left weight balance. Design is required.

Are provided to transmit the left and right grain stem raising devices respectively. The slide transmission shaft is provided with a crank device for taking out power to the reaping device on the input shaft side, and further transmits a star wheel for scraping cereal stems from an intermediate portion of the input shaft. Has become. The input shaft is configured such that a transmission shaft is connected to the upper and lower intermediate portions from the vehicle body side and is transmitted.

[0005] In this conventional transmission mechanism, no consideration is given to distributing the transmission device to the left and right, and the transmission device to the reaper and the starwheel is configured to be offset toward the input shaft. However, there is a problem that a smooth cutting slide cannot be expected due to a loss of weight balance. Moreover, in addition to the above, the transmission shaft connected to the input shaft from the vehicle body side is connected to the intermediate portion of the input shaft through the interior of the pre-cutting device, so that the transfer of the harvested grain culm can be performed. There were obstacles.

The piston 20 is integrally connected to the piston 20 via a transmission cylinder and a support member so as to be slidable left and right. Reference numeral 28 denotes a weeding rod, which is provided at a low position in front of the cutting pre-processing device 4.

As shown in FIGS. 1 and 9, the universal joint shaft 10 has a base portion supported by a gear box 29 provided near the front support portion 7, and extends forward to extend the input shaft 12 Connected to the upper end of the
Further, it is configured so as to be extended forward and connected to the right side (the same applies to the following when viewed in the traveling direction of the traveling vehicle body 6) so as to transmit the grain stem raising device 1. As shown in FIG. 9, the joint shaft covers 31, 31 'are formed in an inverted U-shape, cover the universal joint shaft 10 from above, and overlap the distal end 31' with the base 31. The base and the tip are supported on the fixed side. Reference numeral 32 denotes a support spring, which is configured to tension and support the distal end side 31 ′ upward. Thus, the joint shaft covers 31, 3
1 ′ covers the universal joint shaft 10 while maintaining a state in which it can freely move up, down, left, and right, and can follow freely.
It is configured to prevent wrapping of straw waste and the like and enhance safety in work.

68 'is arranged to set the stop position.

As described above, the supply adjusting device 55 can detect the upper limit and the lower limit of the handling depth adjustment range based on the relationship between the limit switches 68 and 68 'and the pressing piece 66.
The device 60 can be automatically stopped to safely protect the device. Next, as shown in FIG. 10, the left weeding rod 28a is mounted by inserting the rear portion of the lower mounting shaft 69 into the machine frame 70 so as to be freely slidable back and forth, and screwed onto the control motor 71. The shaft 72 is integrally mounted. The control motor 71 moves and adjusts the left weeding rod 28a forward through the screw shaft 72 when the control motor 71 rotates forward, and moves backward when the control motor 71 rotates reversely. And the left weeding rod 28a is
When the reaper 3 is located at the right end, it is at the most retracted position, and the reaper 3 sequentially projects forward in relation to sliding to the left. When the reaper 3 reaches the left end, the highest position is reached. It is configured to be controlled in association with the cutting slide so as to reach the front position.

The left weeding rod 28a thus configured is positioned before, after and during the cutting slide during the work.
Since the visual confirmation can be made from the cockpit 73, the reaping operation can be performed while observing the relative position between the row of cereals and the left end of the pre-cutting device 4. In the drawing, 74 is a Glen tank, 75 is a discharge auger, and 76 is an input pulley.

Next, the operation will be described. First,
The rotational power that reaches the input pulley 76 while starting the engine and transmitting through the rotating parts of the fuselage passes through the transmission 33 of the gear box 29, the vertical shaft 34, the universal joint shaft 10, and The right culm raising device 1 is transmitted. The rotational power is transmitted to the gear 3 according to the transmission path shown in FIG.
0, 30 'to the input shaft 12 and the lower gear 2
4 and 24 ′ to reach the moving transmission shaft 11, and further from the crank device 14 to the reaping device 3 (sliding blade 43) via the reaping transmission lot 15 and the swinging rod 16. The light is transmitted to the output shaft 13 via 25 and 25 '.

There is an advantage that the vibrations can be offset by maintaining the relationship described above and the occurrence of vibrations can be reduced. And the grain stalk scraping and conveying device 2,
2 ′ are gears 44, 45 constituting the power take-out portion 17.
And transmitted from the left-hand star wheel 26 to the right-hand star wheel 26, and the
Is transmitted. Then, the left grain stem raising device 1 ′ is transmitted from the upper end of the output shaft 13 via the intermediate shaft 46 and the raising shaft 47.

As described above, when the rotating parts of the pre-cutting device 4 and the threshing device 5 are transmitted, the combine performs the cutting and threshing action of the culm in the field while moving the traveling vehicle body 6 forward.
In this case, the cereal stem raising devices 1 and 1 ′ adjust the transmission 33 in two stages according to the degree of lodging of the cereal stem in the field, and when the degree of lodging is large, raise the elevating speed to a high speed and appropriately. Can work while raising. The culm that has reached the mowing device 3 and has been cut off is passed on from the cereal stalk scraping and conveying devices 2 and 2 ′ to the supply adjusting device 55, is conveyed upward, is transferred to the feed chain, and is transferred to the threshing device 5 Supplied to

During such work, the universal joint shaft 1
0 is erected at a position detouring upward avoiding the interior of the pre-cutting device 4, so that the grain culm can be properly conveyed without being obstructed by being away from the conveying route of the cereal culm. Further, in the case of the embodiment, since the lower portion of the reinforcing frame 49 and the handle portion 54 of the mounting pin 53 are in a horizontal state at the same height position, a practical effect that does not interfere with the transported grain culm is provided. There is.

Next, the slide operation of the pre-cutting device 4 will be described. First, in FIG. 4, the slide device 9 is pressure-fed from a hydraulic pump (not shown), and is
When oil is supplied to the piston a, the piston 20 moves to the right (FIG. 4).
), And the integrated pre-cutting device 4 slides in the same direction. Conversely, when oil is supplied to the right chamber 19b, the slide device 9
0 is slid to the left and the pre-cutting device 4 is slid to the left with respect to the cutting support frame 8.

As described above, in the pre-cutting device 4, when the slide device 9 slides left and right with respect to the traveling vehicle body 6, the transmission mechanism is distributed to the left and right sides to maintain the right and left weight balance.
