[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled combine harvesting culm inheriting device, and the self-propelled combine is slid left and right in front of a threshing unit mounted on a traveling platform. A free cutting section is provided, and the grain stem root side cut by the cutting section is sent back by the vertical transport chain that changes the posture following the slide and is passed to the feed chain starting end side of the threshing section. is there.

2. Description of the Related Art As described above, a cutting unit that slides in the left-right direction and a feeder of a threshing unit by a vertical transport chain that changes the posture of the culm cut by the cutting unit following the slide of the cutting unit. The self-propelled combine to be succeeded to the chain side has a structure which is already known as described in Japanese Patent Publication No. 53-27171 or the like. Due to the change of the posture, the positional relationship between the feed chain and the starting point of the pinching by the pinching rail fluctuates and it is too far or too close, and the transfer action from the end of the vertical transport chain to the feed chain side lacks smoothness, and Phenomena such as stagnant clogging occur.

[0003]

SUMMARY OF THE INVENTION The present invention is directed to a vertical transport in which such a cutting part that slides in the left-right direction and a grain stem cut by the cutting part are changed in posture by following the slide of the cutting part. This is intended to eliminate the occurrence of the above-mentioned phenomena and to facilitate the inheriting action of the chain that is transferred to the feed chain side of the threshing unit by a chain.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a self-propelled combine constructed as described at the beginning of the present invention. The gripping start end point where the rail is opposed to is fluctuated back and forth in the longitudinal direction of the gripping rail so that the relative position between the gripping start end point and the transport end part of the vertical transport chain is always kept constant. It is characterized by having done.

[0005]

With this configuration, when the mowing unit is slid to the left or right to perform mowing and threshing, the culm stem side is pinched following the slide and passed to the feed chain side of the threshing unit. The position of the transport chain is changed, and the relative position between the nipping start point where the feed chain and the nipping rail are opposed to each other and the transport end part of the vertical transport chain fluctuate. In conjunction with the slide of the section, the starting end of the pinch is moved to the transport end of the vertical transport chain.
This is corrected so as to keep the relative position of the vertical transport chain constant, and the threshing process is performed by smoothly performing the transfer operation from the transport end portion of the vertical transport chain to the feed chain side.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram showing the overall structure of a combine harvester according to the present invention; FIG. (A) Threshing section in which feed chain (3) is stretched to the left and handle cylinder (6) and swing sorter (7) are built in. (B) is a cutting frame (8). ), A cutting section provided integrally with a weeding board (9), a raising case (10), a cutting blade (11), etc., and a cutting section provided in front of the threshing section (A). ) · A grain culm transport consisting of a tipping tine (12) or the like, which is interposed between the reaping section (B) and the threshing section (A) and supplies the reaped section (B) to the threshing section (A). Mechanism, (D) is a straw processing unit that looks into the end of the straw chain (13), (E)
Is a control operation unit, and (14) is a grain tank for storing the grains from the threshing unit (A) through a fryer (15), and continuously cut and cut the planted grain culm. The husk is configured to be threshed.

Therefore, as shown in FIGS. 1 and 3, the cutting frame (8) is integrated with a horizontally long box (16) extending forward from the threshing section (A). The bevel gear (18) that rotates at a fixed position is built in the horizontally long box (16) and is supported by a support member (17) configured as described above. The right and left screw shaft (19)
Through this box (16)
8), and the mowing part (B) is slid to the left or right by an appropriate amount by forward and reverse rotation of the bevel gear (18).

Further, (20) is a telescopic rod-shaped body whose rear side is rotatably supported by a shaft cylinder (21), the front end of which is connected to the cutting section (B), and which is vertically transported from the rear side. The vertical transport chain (2) is held by an extending member (22) extending to the chain (2) side, and the vertical transport chain (2) follows the sliding of the cutting unit (B) in the left-right direction, and the shaft cylinder. It turns around (21) as a fulcrum and its posture is changed, so that the position of the transport end portion (Q) fluctuates back and forth.

Next, as shown in FIG. 2 and FIG. 1, a pinching rail (4) is provided on the upper side of the feed chain (3) to form an under chain method. On the starting end side, an adjustment clamping rail (4a) is provided which is movable in the longitudinal direction of the clamping rail (4), that is, in the front-rear direction. The adjustment clamping rail (4a) and the elongated hole (23) are provided. ), The operating bracket (24) and the right end of the cutting frame (8) are connected to each other by a wire (25), and the adjusting clip (4a) is moved by the slide of the cutting section (B). And the adjustment clamping rail (4a) is configured to change the clamping start end point (P) opposed to the feed chain (3). (26) is a compression spring.

Thus, if the cutting unit (B) slides to the right by an appropriate amount as shown by the imaginary line (A), the telescopic rod-like body (20) rotates as shown by the imaginary line (B). The posture of the transport chain (2) is changed as indicated by the imaginary line (c), and the transport terminal end (Q) moves forward so as to move away from the nipping start point (P) on the adjustment nipping rail (4a) side. At the same time, the adjusting clamping rail (4a) protrudes forward via the wire (25) and the operating bracket (24) to change the clamping starting end point (P) to the front side. Is corrected so that the relative position of the vertical transport chain (2) with respect to the transport end (Q) is kept constant.

When the cutting section (B) slides to the left so as to return to its original position, the respective members operate in the reverse manner as described above, and the transport end section (Q) of the vertical transport chain (2) becomes the nipping start end. The adjustment clamping rail (4a) retracts so as to approach the position (P), and the clamping start end position (P) is changed to the rear side to correct the relative position to be constant. (2) Smooth succession of grain culm from feed chain (3).

[0012]

As described in detail above, the harvesting grain culm inheriting device according to the present invention has a cutting section (B) slidable left and right in front of the threshing section (A) mounted on the traveling platform (1). And the feed chain (3) starting end side of the threshing unit (A) is fed back by the vertical transport chain (2) that changes the posture following the slide with the grain stem root side cut by the cutting unit (B). In the self-propelled combine to be inherited by
The feeding starting point (P) where the feed chain (3) and the clamping rail (4) are opposed to each other in conjunction with the slide of the cutting part (B) moves back and forth in the longitudinal direction of the clamping rail (4). Self
And the relative position between the nipping start end point (P) and the transport end part (Q) of the vertical transport chain (2) is always kept constant. The succession of the transfer of the grain stalk from the transport terminal (Q) of the transport chain (2) to the feed chain (3) becomes smooth regardless of the change in the posture of the vertical transport chain (2). The positional relationship between the transport terminal (Q) of the transport chain (2) and the nipping start point (P) on the side of the feed chain (3) fluctuates, resulting in culm spilling or stagnation due to being too far or too close. Never wake up.
