The bolt 64 is formed in each of the mounting frames 25 in an arc hole 65 formed around the drive shaft 35.
, And the tips of the outer two sets of conveyor belts 21 are rotated to correspond to the interval between the bean stalks in the field.

FIGS. 10 and 11 show another embodiment, in which two transmission cases 26 of a conveyor belt 21 of a conveyor 20 are connected and fixed by the connecting tube 50, and a pair of right and left conveyor belts 2 are provided.
The first end is configured to be able to rotate up and down about the transmission shaft 30 at the same time. Attachment frame 2 for left and right conveyor belt 21
5 supports the middle of the link mechanism 67,
A grounding wheel 68 is provided at a lower end of the link mechanism 67, and a double-acting cylinder 69 is connected to an upper end of the link mechanism 67.
Controlled by the control unit 71 based on a signal from 0, the height adjustment of the start end of the conveyor belt 21 is automatically controlled. In this case, a configuration may be adopted in which the grounding wheels 68 are provided on each of the conveyor belts 21 to adjust the height individually, or a configuration in which the start ends of all the conveyor belts 21 are moved up and down at once. That is, in the transmission case 26 of the conveyor belt 21, the transmission shaft 30 protruding from the transmission case 26 is inserted into the transmission cylinder 28, and the transmission cylinder 2
8 is supported by a bearing member 29, but the outer periphery of the transmission cylinder 28 is surrounded by an outer cylinder that can only expand and contract (not shown, this outer cylinder is mounted on the bearing member 29), and both ends of the outer cylinder are When each set of the conveyor belts 21 is fixed to the transmission case 26 and connected,
By moving the start end of one of the conveyor belts 21 up and down, the whole can be moved up and down.

Further, the height detecting unit 70 detects the transport belt 2.
1 is configured to measure the upper and lower amplitude distance of the tip, determine the cross-cutting, and automatically cut off the automatic control of the up-and-down adjustment when crosscutting with a large upper and lower amplitude due to crossing the ridge. Sometimes. The auger frame 8 is rotatably mounted on the transporting device 16 via a known rolling mechanism 72 to perform horizontal control of the reaper 4. 73 is a horizontal sensor.

FIGS. 12 and 13 show another embodiment, in which the engaging grooves 7 are formed on the upper surface of the cover 41 of the conveyor belt 21 of the right and left conveyors 20 among the conveyors 20 arranged side by side.
5 is provided, and an engaging body 77 which is detachably engaged with the engaging groove 75 is attached to the front and rear cylinders 15 provided on the mounting arm 13. In this embodiment, not only the right and left conveyor belts 21 but also the start ends of all the conveyor belts 21 can be moved up and down at once, or the transmission cases 26 of the respective conveyor belts 21 can be connected and fixed by any means. It is possible.

14 and 15 show another embodiment, in which one of the drive shafts 35 of the pair of conveyor belts 21 is provided with a drive transmission gear 78, the other is provided with a passive gear 79, and the drive transmission gear 78 is provided. The transmission case 26 for attaching the drive shaft 35 provided with the passive gear 79 by looping the chain 80 between the transmission gear 26 and the passive gear 79 is omitted. In this case, the chain 80 is connected to the conveyor belt 21 on the side opposite to the path of the opposing grain stem.
It is located between.

Although the embodiments are described separately for the sake of explanation, it is of course possible to combine all or a part of the components, for example, to combine vertical adjustment and interval adjustment. It is. Next, the operation will be described. The beans culm between the left and right conveyor belts 21 is cut at the root by a cutting blade 22 while being clamped by the conveyor belts 21 and further conveyed into the auger frame 8, collected by the auger 9 and conveyed by the conveyor device. At 16, it is transported to the threshing device 3 and threshed.

In this case, the row crop unit 19
The transport belt 21 is hung between the driving roller 23 and the passive roller 24 provided on the mounting frame 25, and the transport belt 2
1 is located at an arbitrary position in front of the auger frame 8, but the terminal end of the conveyor belt 21 is located above the cutting blade 10 and below the raking reel 12, and the front side of the auger 9. Since the auger 9 is positioned lower than the upper surface of the auger 9, the beans culm transported to the end thereof by the transport belt 21 is taken over by the auger 9 while being scraped by the scraping reel 12. It enters the auger frame 8 and is supplied to the threshing device 3.

Thus, each transport belt 2 of the transport device 20
The two transmission cases 26 are connected by a connection tube 50, and the transmission shaft 30 protruding to the left and right outside from the transmission case 26 of each conveyor belt 21 is fitted to the rotary shaft tube 28 so as to be slidable only. Since the rotating shaft cylinder 28 is fixed to the bottom plate 5 via the bearing member 29, when the set bolt 27 is loosened and the screw shaft 62 is rotated by the handle 63, the screw shaft 6 is rotated.
2, the projection 61 of the transmission case 26 screwed to the left and right is moved left and right, and the transmission shaft 30 slides with respect to the rotary shaft cylinder 28, so that the left and right positions of each transmission case 26 can be changed. Can be made to correspond to the strip of bean culm, and the harvesting and transporting becomes smooth.

In the second embodiment shown in FIGS. 7 to 9, when the bolt 64 is loosened and the tip of the mounting frame 25 of the conveyor belt 21 is swung right and left, the bolt 64
Moves in the arc hole 65 centered on the drive shaft 35 of the mounting frame 25, and rotates the tip of the conveyor belt 21 to correspond to the interval between the bean stalks in the field.

In the embodiments of FIGS. 10 and 11, the control unit 71 expands and contracts the double-acting cylinder 69 in response to a signal from the height detecting unit 70, and the link mechanism 67 is grounded by the expansion and contraction of the double-acting cylinder 69. The height of the start end of the conveyor belt 21 is adjusted by moving the wheel 68 up and down.

Although not shown, the auger frame 8 rolls up and down with respect to the conveyor 16 by the expansion and contraction of a rolling cylinder and a rolling mechanism 72. Work smoothly by preventing rushing into the field.

In the cross-cutting performed over the ridges in the field, the vertical amplitude is large, and the height adjustment may adversely affect the height adjustment.
When the determination of the side cutting is performed by measuring the vertical distance between the top and bottom of the head, the automatic control of the vertical adjustment is automatically cut off.

In the embodiment shown in FIGS. 12 and 13, when the front and rear cylinders 15 provided on the mounting arm 13 are reduced, the engaging member 77 engages with the engaging groove 75 to pull the engaging member 76. The start end of the conveyor belt 21 moves upward, and conversely, when the engaging body 77 moves forward, the start end of the conveyor belt 21 moves downward.

In the embodiment shown in FIGS. 14 and 15, a drive transmission gear 78 is provided on the drive shaft 35 of one conveyor belt 21 and a passive gear 79 is provided on the other. Between 80 and Chien Chien,
Since the transmission case 26 for mounting the drive shaft 35 provided with the passive gear 79 is omitted, the weight and cost are reduced.

As described above, the positions of the tips of the conveyor belts 21 of the plurality of conveyors 20 can be made to correspond to the strips of the bean culm in the field, thereby improving workability.
