Further, the boss 19 fixed to the lifting support frame 13 and the drive shaft 20 on the mowing moving section A side are screw-fitted, and the left and right moving means 14
(In this embodiment, an electric motor is used, but another method may be used.)
The reaping moving part A is configured to move in the left-right direction. The power transmission system for driving the raising device 5, the stock transfer device 6, and the cutting blade device 7 of the mowing moving section A is inputted and driven via the telescopic universal joint 21. [0010] When the combine is run, the grain stalks that have been weeded by the weeding tool 4 and caused by the raising device 5 are cut by the cutting blade device 7 and the starting end of the stock transfer device 6 of the cutting moving unit A. From the end to the end. The grain culm transported to the end of the stock transport device 6 is taken over by the vertical transport device 8 and transported to the threshing device 3 at the rear, where it is threshed and sorted. In the combine having the above-described structure and movement, the front end of the uncutted culm guiding device 9 made of a pipe material is pivoted around the pivotal support portion C having a longitudinal axis on the side of the cutting moving portion A. It freely pivots, and its rear end is movably supported in the longitudinal direction by a ring-shaped slide receiver 22 at the rear of the machine body and at the rear of the threshing device 3. Further, an intermediate portion of the uncut culm culm guiding device 9 is connected by an elastic body 9a (rubber in this embodiment), and a pipe member is constituted by a front half 9e and a rear half 9f. The elastic body 9a and the uncut kernel culm guiding device 9
As shown in FIG. 13, as shown in FIG. 13, both end faces of the rubber 9 a are made to have a small diameter, fitted to the inner peripheral edge of the pipe of the uncut culm culm guide device 9, and fixed with the roll pin 23 (another method may be used). Thus, the front half 9e and the rear half 9f are relatively swung. The uncut kernel culm guide device 9 is engaged at a position approaching (stowed) to the traveling machine body 2 side, at an uncut culm side, that is, at a state where it is extended outside the machine body, and at any intermediate position between them. One end of an arm 10 having a lock device 11 for stopping is supported on the mowing moving unit A side.
The lock device 11 is attached to the rear side of a support rod 4a that attaches the weeding implement 4 to the front side. FIGS. 5 and 6 show the support rod 4a and the lock device 11 respectively.
The relationship between the arm and the arm 10 is shown. FIG. 6 is a diagram viewed from the direction D in FIG. A support 4b is provided on the support rod 4a, and the lock device 11 is pivotally supported by a pin 11d supported by the support 4b. The pin 11d is provided with a pipe 11a. An arm 10 for accommodating the uncut culm guiding device 9 inside or projecting outward is connected to the pipe 1a.
1a, and a lock plate 11c is provided at each end of the pipe 11a with a tension spring 11b.
Is provided via As shown in FIG. 7, lock plates 11c provided at both ends of a pipe 11a are connected to tension springs 11b.
Is constantly pulled toward the pipe 11a, the inner peripheral edge of the lock plate 11c and the arm 10 are rubbed, and the arm 10 is locked. Therefore, the related position does not shift, and the uncut kernel culm guide device 9 is fixed. When the arm 10 is moved with respect to the mowing moving part A, as shown in FIG.
By setting the lock plates 11c provided at both ends of the pipe 1a in a parallel state along the end face of the pipe 11a,
Since the friction between the inner peripheral edge of the lock plate 11c and the arm 10 is released, the arm 10 can move in the pipe 11a. The overhang amount can be adjusted in the lateral direction about C. The length of the pipe 11a in the longitudinal direction is set to a length that is easy for a person to release and is about the distance between the thumb and the index finger so that the lock plate 11c can be released with one hand.
With such a lock device 11, the arm 10 can be locked to the pipe 11a at any position, and the uncut culm guide device 9 can also be locked at any position. FIG. 9 shows the positional relationship between the mowing moving part A and the uncut kernel culm guiding device 9 when the mowing moving part A moves in the left-right direction. The state shown in (a) of FIG.
Indicates a state moved to the right end with respect to the aircraft, and (b) indicates a state moved to the left end. As described above, since the lock device 11 is provided in the mowing moving unit A, the mowing moving unit A
No matter where it is in the left-right direction of the aircraft,
The lock device 11 moves in the left-right direction together with the cutting moving unit A, and accordingly, the uncut grain culm guiding device 9 for the cutting moving unit A
Is not changed, and the planted grain culm is guided further outward from the outer side surface of the mowing moving portion A, and does not catch on the mowing moving portion A or the body. Further, since the rear portion of the uncut culm guiding device 9 is slidably received by the slide receiver 22, the cutting moving portion A moves in the left and right direction or the up and down direction, or moves from the inside storage position to the outside. It is possible to absorb the amount of change in length when the uncut grain culm guide device 9 is moved in and out of the section of the overhanging position. Furthermore, an elastic body 9
Since a is provided, the amount of change in the front part and the rear part of the uncut culm guiding device 9 can be absorbed, and the impact can be absorbed when it comes into contact with an obstacle, thereby protecting the machine body. Conventionally,
Although a spring or a mechanical link mechanism was used instead of the elastic body 9a, a problem that the uncut planted grain culm was caught due to the convex portion occurred. Even so, since the elastic body 9a is formed by a curved surface portion, the planted cereal stem does not catch on. FIG. 10 shows another embodiment of the rear part of the uncut grain culm guiding device 9. Instead of the slide receiver 22, a bar 9b is pivotally supported at a pivot 9c.
Supported the inside of the uncut culm guiding device 9 slidably in the longitudinal direction. Thereby, while the cutting moving part A moves in the left-right direction and the up-down direction, the change amount of the length of the uncut kernel culm guide device 9 can be absorbed, and the distance between the inside storage position and the outside protrusion position can be absorbed. The amount of change in length when moved can also be absorbed.
Further, since the bar 9b extends rearward from the rotation fulcrum 9c and is formed in a curved surface shape between the bar 9b and the sliding part in the longitudinal direction with the uncut grain culm guide device 9, if the plant is planted. Even if the standing stalk enters the space between the uncut stalk guiding device 9 and the machine,
When the body moves, it passes smoothly without being caught on the rotation fulcrum 9c or the like. FIG. 11 shows an uncut culm guiding device 9 and an arm 1
In the configuration of the plate 10a connecting the 0, the front side in the body traveling direction is a curved surface shape. This allows
Even if the planted cereal stalk enters the space between the uncut stalk culm guide device 9 and the cutting section B, it passes through smoothly for the movement of the machine. FIG. 12 shows the first half 9 of the uncut grain culm guiding device 9.
e, the rear half 9f and the arm 10 were connected by an elastic connecting body 9d. The elastic connector 9d is fitted to the front half 9e, the rear half 9f, and the arm 10 of the uncut mushroom culm guiding device 9, and each is fixed by a roll pin 23. Conventionally, at the time of fall cutting, a large load acts on the mowing moving portion A, and the load also acts on the uncut grain culm guide device 9, which may cause deformation or the like. By doing so, the resistance can be absorbed by the elastic connector 9d, and in particular, the resistance in the direction of the arm 10 can be absorbed.
The breakage of the lock device 11, the uncut culm guiding device 9, and the like can be prevented. Furthermore, even if an obstacle comes into contact with the uncut kernel culm guide device 9 from any direction, the elastic connector 9d can absorb the impact, and the uncut kernel culm guide device 9 and the body can be shocked. Can be protected. With the above configuration, the relative position of the uncut culm guiding device 9 with respect to the outer side surface of the mowing moving section A does not change, so that the uncut culm does not catch on the mowing moving section A or the like. You will be guided smoothly for the movement of. [0019] According to the present invention so configured as described above, un
Use tools to lock and unlock the culm guiding device 9
Without the need to do this.
