It is configured to move the member left and right.

Further, a reaping output case (46) is rotatably mounted to the left and right at an intermediate portion of the left reaping input case (26), and the reaping output case (46) and the right pull-up pipe (38) intermediate portion. By installing a connecting pipe (48) between the mowing work input case (47) to be incorporated into the mowing work input member (47) and rotating the connecting pipe (48) from the mowing output case (46) to the left and right in accordance with the lateral movement of the mowing work member. , Power of each mowing work member is transmitted from the mowing input pulley (44) to the mowing work input case (47) through the left and right mowing input cases (26) (27), the mowing output case (46) and the connecting pipe (48). Is configured to do.

The power input to the mowing work input case (47) in the middle of the right raising pipe (38) is transmitted to each mowing work member, and the right raising pipe (38) is fed from the mowing work input case (47). ), Power is distributed and transmitted to the right pulling drive case (39) and the pulling drive case (40), and the pulling tine (17) and the right star wheel (19) and the pulling belt of the right pulling case (18). (20) is driven, the left star wheel (19) and the left take-in belt (20) are driven, and the power is driven from the take-in drive case (40) into the right gear case (37) through the right pull-up pipe (38). The power of the cutting blade (21) is extracted from the right gear case (37) through the output shaft (49), and the power is transmitted from the right gear case (37) through the slide frame (35). The power is transmitted to the left gear case (37), the power is transmitted from the left gear case (37) to the left pulling drive case (39) through the inside of the left pulling pipe (38), and the pulling tine of the left pulling case (18). (17) is configured to be driven. By the way, the lower part of the right pulling pipe (38) below the take-in drive case (40) is hung down while being swung to the right side of the aircraft through the horizontal pipe (50) and the gear case (51), and the right star wheel (19). Also, it is formed so as not to interfere with the right scraping belt (20).

As shown in FIG. 4, the cutting output case (46) includes a vertical axis (52) which is a horizontal rotation axis of the vertical grain culm conveying member and a horizontal axis which is a vertical rotation axis of the vertical grain culm conveying member. The shaft (53) is integrally provided at a substantially right angle, and the reaping output case (46) is rotatably connected to the bearing portion of the middle part of the left reaping input case (26) via the vertical axis (52) thereof. , A vertical transport drive case (57) for supporting the feed end side of the vertical transport chain (22) and the upper transport tine (23) through the sprockets (54) (55) and the sprocket shaft (56), The vertical transport drive case (57) is rotatably connected to the horizontal axis (53) of the reaping output case (46) so as to follow up and down movement of the reaping work member, and integrally with the transport chain (22). And the feed start end of the upper transport tine (23) is left The right mowing input case (26) (27) is moved up and down around the fulcrum and the left and right movements of the mowing work member are followed, and the vertical conveying chain (22) and the upper conveying tines (23) are fed integrally with this. The starting end side is configured to move left and right with the vertical axis (52) as a fulcrum.

Further, the support pipe (79) is projected and fixed from the reaping work input case (47) rotatably provided to the right pulling pipe (38), and the connecting pipe (48) is attached to the support pipe (79). ) Output side is slidably fitted.

According to the above, the cutting work member of the cutting unit (7) and the vertical conveyance unit are positioned at the slide end position on the left side so that the left traveling crawler (2) does not step on the uncut grain culm. For normal cutting work, slide the cutting part (7) to the slide end position on the right side during middle cutting work, and prevent left and right traveling crawlers (2) from stepping on uncut culms. At the same time, the mowing section (7) at the time of the ridge work is slid to the slide end position on the ridge side to prevent the traveling crawler (2) on the ridge side from riding on the ridge, and also to the left and right of the mowing section (7). By adjusting the slide, it is possible to align with the uncut grain culm. However, as shown in Fig. 2, the above-mentioned items are, when sliding the reaping part to the right side of the ridge side as shown in (A) during the ridge cutting work and then continuing the reaping by cutting back the reaping part. It will be moved to the left side and work like B, but at the time of turning back, it is necessary to stop the aircraft and move the reaping part on the right side to the left side, at that time rotation of the power input pulley (44) It is complicated because it requires an operation to change the direction with a clutch. Moreover, it is even more difficult to perform it manually.

The present invention is to improve the above points so that when the shift lever is put in the reverse side, the mowing section drive member moves the mowing section from the right side to the left side. That is, as shown in FIG. 8, a slide frame (35), which is a male screw, is formed by rotatably fitting an inner cylinder (34) into left and right support pipes (29) (30) and passing the inner cylinder (34). ), The both ends of the rear lateral connecting pipe (33) are integrally connected, and the slide frame (35) is slidably fitted directly in the left and right support pipes (29) (30) as shown in FIG. Both ends of the rear horizontal connecting pipe (33) are integrally connected to both ends of the slide frame (35). Then, one end of the mowing slide lever (80) is connected (81) to the slide frame (35), and the mowing slide lever (80) is constructed so as to be swingable around the shaft (82) of the machine body. At the end of the bar (80), there is a reaper drive member. It is configured so that the core rod (83b) of the electromagnetic solenoid (83) abuts. The reaper driving member may be an optional electromagnetic solenoid. The electromagnetic solenoid (83) is connected to the micro switch (87) provided on the reverse side of the gear shift lever (86) that moves along the gear shift lever guide (85) provided in the operation section via the battery (84). To do. Then move the reaping section to the right manually.

Therefore, when the reaper of FIG. 2 is switched from the A direction on the right side to the B direction, when the shift lever (86) is inserted on the reverse side, the shift lever (86) hits the microswitch (87) and the electromagnetic solenoid is contacted. Since the circuit of (83) is opened, the core rod (83b) projects and pushes one end of the mowing slide lever (80), so that the mowing slide lever (80) swings counterclockwise about the shaft (82). Then, the slide frame (35) moves to the left, and the cutting unit is moved to the left to perform work in the B direction. Therefore, it is not necessary to stop the aircraft one by one and slide the reaper when switching from the right side to the left side. As another embodiment, the two-row cutting combine is designed for wetlands, and the cutting section slides as described above. However, if possible, I would like to mow 3 rows of grain culm that has not fallen down. To solve this problem, the raising case (18) on the right side of the reaping section, that is, the driver's seat side may be fixed, and only the raising case on the left side may be slid. That is, the state (a) in Fig. 3 shows a normal cutting posture, and the left and right tines overlap because they are cutting two rows, but in the state (b) where three rows are cut, the left-side raising case Slide (18) to use. In this case, a raised culm can be transported 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. In other words, a grain culm that is normally two-row cut but is napped allows three-row cutting. In order to have the above structure, the slide frame (35) is directly fitted to the support pipes (29) and (30) shown in FIG. 8, and further divided into right slide frame (35) and left slide. 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 pipes (29) and (30) are long. In addition, 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 also expandable and contractable in a normal configuration.

[Effect of device]

 According to the present invention, when the gear shift lever is moved to the reverse side, the mowing part can be moved from the right side to the left side by the mowing drive member. Since the reaping unit that had been moved to the right side can automatically return to the left side for work, there is no need to stop the aircraft one by one to move the reaping unit, which is not complicated. After moving to the left side, the mowing operation can be continued because it is a normal mowing. Further, according to the present invention, the diagonal cutting work required for turning can be facilitated.
