Abstract

PURPOSE: To obtain a combine harvester capable of reaping and threshing grain straws planted on the side of a balk, preventing the threshing miss of the grain straws, and well threshing the grain straws. CONSTITUTION: A threshing depth-controlling and carrying device 5 for carrying grain straws K reaped in a reaping section 2 in a state capable of automatically controlling the threshing depth with a grain straw-detecting sensor 53 is disposed, and the carried grain straws are fed into a nipping carrier 3 comprising a nipping rail 3b and a feed chain 3a. When the grain straw-detecting sensor 53 detects that the grain straws are extremely short, the threshing depth-controlling and carrying device 5 is operated in the deepest threshing direction, and the usual nipping and carrying state with the feed chain 3a and the nipping rail 3b of the threshing machine is weakened or released. Thus, the threshing depth-controlling and carrying device 5, and the feed chain 3a and the nipping rail 3b of the threshing machine are interlocked and connected to each other. A continuously carrying section 6a having a continuously carrying rail 6 is formed at the starting edge of the feed chain 3a between the threshing depth- controlling and carrying device 5 and the nipping carrier 3, and the continuously carrying rail 6 and the nipping rail 3b are attached and supported on the frame of the combine harvester.

うに構成されている。The grain culm detection sensor 53 is a long culm sensor 53a, which is composed of a contact piece which comes into contact with the grain culm K at a predetermined interval from the upper side to the lower side so as to detect the contact so that the grain culm K can be rotated and retracted.
The middle culm sensor 53b and the short culm sensor 53c are configured as a pair, and are integrally attached to the handling depth adjusting carrier 5 by the U-shaped frame 54 in the opposite direction. On the other hand, the nipping rail 3b of the nipping carrier 3 arranged on the side of the handling chamber is
A switching mechanism 7 operated via a wire 71 and an engagement pin 52b planted at the upper end of the actuating member 52a swings up and down. When the handling depth adjustment carrier 5 is detected by the grain culm detection sensor 53 to be the shortest culm and is operated in the maximum handling depth direction (downward) by interlocking with the operating member 52a, the normal handling shown in FIG. It is configured to be able to switch from the holding and conveying posture to the holding force releasing and conveying posture shown in FIG.

As shown in FIG. 3, the rear portion of the rail support 30 is pivotally supported by a support shaft 32, and the switching mechanism 7 is provided in a long hole 33 opened in the front portion.
The lower end shaft 70a of the elevating arm 70 constituting the above is fitted and engaged.

By pulling the arm portion on the other side by the tension spring 73, the rail support base 30 is pressed downward (in a normal holding and conveying posture) via the lower end shaft 70a. When the wire 71 is pulled against the tension spring 73 by the above-described structure, the elevating arm 70 moves the lower end shaft (70a) in the elongated hole 33, and the front side F of the rail support 30 is moved.
Can be rotated up about the support shaft 32 on the rear side.

The short culm K, which has been conveyed via a, is spread between the holding rails 3b and the feed chain 3a, which are spread forward and become narrower.
In the process of being held and conveyed loosely, the tip of the short culm inserted into the handling chamber 4a comes into contact with the handling barrel 4b and is gradually pulled in. Therefore, the short culm is supplied by the handling barrel 4b together with the culm and processed in the handling chamber 4a as if it were processed by the thresher type thresher, and is effectively threshed without being left untreated.

Since the command operation is performed to lower the front of the adjusted conveyance body 5 about the drive fulcrum axis P, the operation member 52a engaging with the hook 50a is moved downward to loosen the wire 71. When the wire 71 is loosened in this way, the tension spring 73
(FIG. 3) pushes and rotates the lower end shaft 70a of the elevating arm 70 downward, and the holding rail 3 is held through the rail support 30.
It is possible to return and stop b to the original sandwiching and transporting posture, and transport the long culm while sandwiching the long culm between the sandwiching rail 3b and the feed chain 3a in a predetermined manner to perform normal sandwiching and threshing.

るようにしている。Further, the transfer rail 6 is attached and fixed to the threshing machine frame by a mounting shaft 60 so that the continuous transfer state of the solid line shown in FIG. 5 can be switched to the hand-operated grain culm feeding posture shown by the dotted line. The relay rail support frame 61 is provided via a spring pin 62. The transfer rail 6 is supported independently of the sandwiching rail 3b.
When the gripping force is released, the short culm sent from the handling depth adjusting transporter 5 positioned in the solid line is reliably transported.

れる。The harvesting work with the combine constructed as described above does not require manual cutting of grain culms to be planted on the sides of low ridges, which was conventionally done by hand cutting as pillow cutting.
Can be directly mowed and threshed. That is, in the mowing work in this case, the mowing unit 2 is raised, and the grass body and one side of the mowing blade 2b are aligned in a position close to the ridge surface, and within the cutting width protruding above the ridge surface. The stalk side of a certain grain culm is cut short and conveyed collectively, and transferred to the handling depth adjusting carrier 5.

The drive mechanism 52 is driven to rotate the handling depth adjusting carrier 5 in the deepest handling direction about the drive fulcrum axis P shown in FIG. Accordingly, the sandwiching / conveying body 3 is switched to the normal sandwiching / conveying state by being weakened or released by moving the sandwiching rail 3b upward through the wire 71 and the switching mechanism 7 configured as described above. The culm is transferred to the feed chain 3b from the terminal end of the handling depth adjusting carrier 5 and is reliably fed through the transfer rail 6 without spillage or the like.

なうことができる。Therefore, when an extremely short culm is conveyed, the gripping conveyor is automatically switched and adjusted so as to release the clamping force by the operation of the handling depth adjusting conveyor, so that an efficient cutting and threshing work can be performed. In addition to the above, it is possible to provide a labor-saving combine that enables ridge cutting that does not require hand cutting work. In addition, by performing the threshing treatment of the short culm in the handling room, it is possible to favorably perform the harvesting work without leaving any untreated residue.
