BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine equipped with a two-row cutting section in front of a threshing machine.

[0002]

2. Description of the Related Art A combine equipped with a two-row cutting section in front of a threshing machine, in which a 2-row cutting section including a cutting work member and a grain culm conveying member is provided so as to be slidable to the left and right, is a real open flat. It is known from JP-A-5-29334.

[0003]

In the above-mentioned combine, the operation is complicated because the body is temporarily stopped and then slid to slide the reaping unit. Therefore, an object of the present invention is to provide a combine that can automatically move the reaping unit from the right side to the left side at the time of turning back without stopping the aircraft one by one.

[0004]

The present invention provides the following combine in order to achieve the above object. That is, in a combine equipped with a mowing unit in front of the threshing machine, a mowing unit including a mowing work member and a grain culm transport member is slidably provided left and right, and a driving member for moving the mowing unit from right to left is provided. It is a combine characterized in that it is connected to the reverse side of the shift lever.

[0005]

When the shift lever is moved to the reverse side, the mowing portion is automatically moved from right to left by the mowing portion drive member.

It is formed so as not to interfere with the right scraping belt (20).

As shown in FIG. 4, the cutting output case (4)
6) is a vertical axis (5) which is a left-right rotation axis of the vertical conveying member of the grain culm.
2), and the horizontal axis (5)
3) are provided integrally at substantially right angles, and the longitudinal axis (52)
The cutting output case (46) is rotatably connected to the bearing portion in the middle of the left cutting input case (26) through
The vertical transport chain (22) and the upper transport tine (23)
A vertical transport drive case (57) is provided for supporting the feed end side of the mower through sprockets (54) and (55) and a sprocket shaft (56), and the vertical transport drive case (57) is attached to the cutting output case (46). The transfer chain (22) and the upper transfer tine (23) are rotatably connected to the horizontal shaft (53) and follow the lifting and lowering of the reaping work member.
Is moved up and down with the left and right reaping input cases (26) and (27) as fulcrums, and following the left and right movement of the reaping work member, integrally with the vertical transport chain (22) and the upper transport tine ( The vertical axis (52) indicates the feed start end side of (23).
Is moved left and right around the fulcrum.

A support pipe (79) is projected and fixed from a mowing work input case (47) rotatably provided with respect to the right raising pipe (38), and the connecting pipe (48) is connected to the support pipe (79). The output side is slidably fitted.

According to the above, the cutting section (7) is so arranged that the left traveling crawler (2) does not step on the uncut culm.
The mowing work member and the vertical transport unit are positioned at the left slide end position, and the normal mowing operation is performed. During the middle split operation, the mowing unit (7) is slid to the right slide end position to travel left and right. The crawler (2) prevents stepping on the uncut grain culm and, at the time of ridge work, slides the mowing part (7) to the slide end position on the ridge side, and the traveling crawler (2) on the ridge side moves on the ridge. Riding can be prevented, and the cutting of the uncut culm row can be performed by adjusting the left and right sliding of the cutting unit (7). However, as shown in FIG. 2, when the mowing part is slid to the right side of the ridge side as shown in FIG. When the vehicle is turned back, the body must be stopped and the reaping unit on the right side must be moved to the left side. At this time, the rotation direction of the power input pulley (44) is changed by the clutch. It is complicated because an operation to change is required. Further, when performing manually, it is even more so.

The present invention is an improvement of the present invention, in which the mowing portion is moved from the right side to the left side by the mowing portion driving member when the shift lever is moved backward. That is, left and right support pipes (29) (30) as shown in FIG.
The inner cylinder (34) is rotatably fitted in the inner cylinder (3).
The structure in which both ends of the rear horizontal connection pipe (33) are integrally connected to both ends of the slide frame (35), which is a male screw that passes through 4), is stopped, and the left and right support pipes (29) (3)
The slide frame (35) is slidably fitted directly into the slide frame (0), and both ends of the rear horizontal connection pipe (33) are integrally connected to both ends of the slide frame (35). Then, one end of the cutting slide lever (80) is connected (81) to the slide frame (35), and the cutting slide lever (80) is configured to be able to swing about the body shaft (82). 80) At the end is a mowing part drive member. The core rod (83b) of the electromagnetic solenoid (83) is configured to abut. The mowing unit drive member may employ any other than the electromagnetic solenoid. The electromagnetic solenoid (83) is connected via a battery (84) to a microswitch (87) provided on the reverse side of a shift lever (86) that moves along a shift lever guide (85) provided on an operation unit. The right side of the mowing part is moved manually.

Therefore, A in FIG.
When switching from the direction to the direction B, when the shift lever (86) is turned to the reverse side, the shift lever (86) hits the micro switch (87) and the circuit of the electromagnetic solenoid (83) is opened, so that the core rod (83b) is opened. ) Protrudes and pushes one end of the cutting slide lever (80), so that the cutting slide lever (80) swings counterclockwise about the shaft (82), and the slide frame (35) moves to the left to cut. The part is moved to the left to perform the operation in the B direction. Therefore, it is not necessary to stop the airframe and slide the reaping unit at the time of switching from the right side to the left side. In addition, as another embodiment, the cutting section slides as described above in order to cope with wet fields in the two-row cutting combine. However, if possible, I always want to cut three rows of culms that have not fallen. In order to solve this, the raising case (18) on the right side of the reaper, that is, the driver's seat side may be fixed, and only the left raising case may be slid. That is, the state (a) in FIG. 3 shows a normal mowing posture, and the left and right tines overlap for two-row cutting. However, when the three-row cutting is in the (b) state, the left raising case ( 18) is used by sliding. In this case, it is possible to transport the raised culm even if the left and right raising cases are separated. Accordingly, those minute grass plates is the case L ₁ in two rows mowing is L ₁ <L ₂ is the case of 3-like mowing L _2. That is, the stalks that are normally raised while being two-row cut enable three-row cut. In order to obtain the above configuration, the slide frame (35) is directly fitted to the support pipes (29) and (30) shown in FIG. The frame (35) is configured to be separated, and the rear horizontal connecting pipe (33) is divided so that the left rear connecting pipe (33) is separated from the right rear horizontal connecting pipe (33). In this case, the guide frame (31) and the support pipe (29)
(30) is configured to be long. Further, the length of expansion and contraction of the support pipe (79) and the connecting pipe (48) shown in FIG. 4 is increased, and the drive shaft in the pipe is made of a normal structure and can be expanded and contracted.

[0017]

According to the present invention, the mowing portion can be moved from the right side to the left side by the mowing drive member when the speed change lever is moved to the reverse side. When the vehicle moves backward, the reaping unit, which has been moved to the right side in advance, can be automatically returned to the left side to perform work. Therefore, it is not necessary to stop the machine body and move the reaping unit, which is not complicated. After moving to the left side, the normal reaping is performed, so that the reaping operation can be continued. Further, according to the present invention, the oblique cutting work required for turning is also facilitated.
