[Detailed description of the invention] This invention is used for combine harvesters, self-propelled self-threshering machines, stationary thresher machines, etc. for threshing and collecting various types of grains, and the stem culm connected to the threshing machine part. This relates to the composition of a mechanism for transporting and supplying a group of stalks and culms after threshing to a processing device, and the purpose thereof is to completely prevent the stalks from wrapping around the rotating part of the threshing machine. To obtain a mechanism capable of smoothly and orderly transporting stem culms from the core, and supplying stem culms to the processing device in an orderly manner while ensuring a posture that allows the stem culms to be processed satisfactorily by the processing device thereafter. be.

Hereinafter, this will be explained in detail with reference to a specific example shown in the drawings.

The drawing illustrates the case where the mechanism of the present invention is applied to a combine harvester for rice and wheat. C is a combine machine body, which has a reaping conveyance part 3 on the front part of a machine stand 2 supported by a running part 1. It is equipped to be able to be raised and lowered, and has a threshing section 4, a grain extraction section 5, and a control operation section 6 on the top. It is formed by appropriately arranging the engine 7 and the like.

The threshing section 4 is formed so as to be housed in a handling chamber with the handling trunk axis facing the direction of movement of the machine.
The front part facing the culm is the supply port, the rear part is the stem culm discharge port 8, and the outer part of the handling port that opens on the side wall between the two is located slightly behind the supply port and the discharge port 8. A foot chain mechanism 9 is wound around the entire length.

The foot chain mechanism 9 has a gripping mechanism 10 installed corresponding to the lower side of the winding to form a transfer path 11.
The starting end of the transfer path 11 is connected to the plant head conveyance chino 3' of the reaping conveyance section 3 described above, and the rear end thereof is opened somewhere slightly rearward and above the stem culm discharge port 8.

A stem culm processing device (cylindrical cutter, 12) is located somewhere below the open end portion of the transfer path 11.
The threshing part 4 is attached to the frame body with the intake port 1.3 opening diagonally forward.

A take-in roller 14 is installed on the side near the front of the take-in opening of the cutter 12 so as to rotate in the direction of arrow A, and this roller 14 has a scraping finger that protrudes maximum at the diagonally upper front part of the take-in roller 14. 15 is provided to forcibly scrape the stem culms discharged from the transfer lattice end of the foot chain mechanism 9 into the cutter 12.

The scraping finger 15 is positioned so as to protrude and retract from the take-in roller 14 at a position that is closer to the inside of the body C than the foot chain mechanism 9 in a plan view, and the finger 15 and the foot chain mechanism 9 A guide body 16 extending from the fixing member on the foot chain mechanism 9 side is positioned between.

The guide body 16 has a portion connected to the mounting base extended obliquely downward, and is positioned so as to cross the terminal end of the transfer path 11, and its extended free end 1γ approaches the outer periphery of the upper rear side of the take-in roller 14. It is maintained in such a way that it

In addition, the reference numeral 18 in the figure is a stem culm grouping plate constituting the rear end of the pinching plate mechanism 10, whose front end is rotatably supported by a pivot 19.
The free end side is held so as to elastically swing by a spring-like holding member 20, 21 is a rotating shaft for winding and hanging the foot chain mechanism 9, 22 is a sprocket fitted to the shaft, 23 is a rotating shaft for winding and hanging the foot chain mechanism 9; A foot chain cover 24 is a spring that elastically biases the guide body 16 in a direction closer to the take-in roller 14 side, S indicates a group of culms, and 25 indicates a discharge port of the cutter 12.

Next, to explain the operation of the mechanism of the present invention, the engine 7
When the machine C is started and the machine body C is operated in the machine body parts 1, 3, 4, and 512 and the traveling section 1 moves the machine C in a field with erected stems and culms, the erected stems and culms are successively raised by the reaping and conveying section 3. The harvested plants are transported and laid down on their sides, and transported so that the tips of the ears reach the supply port and the stem ends reach the starting end of the transfer path 11 of the foot chain mechanism 9.
And this supplying stem culm group has a foot chain 9 at its base.
During this transfer, the ears of the stem and culm group are held in the handling chamber and are not transferred, so they are subjected to the action of the handling barrel and their grains are The grains are removed and taken out to the grain removal section 5 through a well-known sorting process, and the stem culm group after threshing is further transported to the stem culm discharge port 8. When the stem culm group that has reached the core is handled particularly deeply, the base part of the stem is clamped between the foot chain 9 and the stem culm grouping board 18, and the individual parts near the tip of the stem are held in advance. Due to the sliding resistance with the threshing part forming material, the grain is in a backward position in the transport direction,
The grains sent to the stalk culm group are returned into the threshing machine through eight stalk culm discharge ports.

When the terminal end 1 of the stem culm group plate 18 is broken, the clamping state between the plant base and the foot chain 9 is released, and the stem culm group extends along the lower surface of the guide body 16. At this time, the guide body 16 is located inside the foot chain mechanism 9 and closer to the foot chain mechanism than the scraping fingers 15, and is in contact with the stem culm. Since the braking is applied to prevent the base of the stem culm from moving too far ahead, the stem culm group, which is in a position where the tip of the stalk is lagging as described above, is not changed to a position where the tip of the stem is lagging any further. The feed roller 1 is guided and fed to the raking action area while ensuring a posture that crosses the raking finger 15.
4, it is guided into the cutter 12 and processed, and after processing is discharged from the discharge port 25.

As explained above, in the present invention, the stem culm processing device 12 is disposed on the rear side of the threshing machine 4, and the foot chain mechanism 9 of the threshing machine is disposed between the threshing machine and the stem culm processing device. A stem culm treatment system in which a guide body 16 is provided to prevent the stem culm from being entangled in the stem culm, and cooperates with the raking fingers 15 of the stem culm processing device to guide and supply the stem culm to the processing device 12 side. In terms of the structure for supplying stem culms to the device, the stem culm processing device 12 is installed so as to be able to receive stem culms directly from the end of the foot chain mechanism of the threshing machine without going through another conveyance chain;
The intake roller 14 is provided so as to be perpendicular to the foot chain mechanism, and the guide body 16 is provided on the inner side of the tip of the foot chain mechanism 9 so as to be related to the locus of action at the end of the foot chain mechanism 9. Since the raking fingers 15 are positioned closer to the tip of the stalk, the tip of the stalk is sent out with a lag in the direction of transport, relative to the base of the plant, due to short culms, deep handling, etc. Even when feeding a group of culms to a processing device, when the scraping finger acts on the tip of the stem culm, the guide body moves closer to the base of the stem for the stem culm that is no longer clamped by the foot chain mechanism. Since the contact is guided at a close position, a brake is applied to the base of the plant that is moving forward, and the stem culm group that is taken into the processing device by the raking fingers is kept in a good posture so that it will not come off from the raking fingers. This ensures that the grains are taken in without accidentally falling into the culm outlet 8 and damaging the function of the threshing machine.

In particular, when the stem culm to be threshed is an extremely short culm, the length of the stem culm is adjusted to be as deep as possible into the threshing machine to eliminate any unhandled parts. In such a case, the stem culm is transported in such a state that the plant base hardly protrudes outward from the foot chain mechanism.However, since the guide body 16 is configured as described above, the guide body 16 is not connected to the foot chain mechanism. Scratching finger 15 located inside from 9
Since it is located closer to the foot chain mechanism than the foot chain mechanism, the guide body always comes into contact with the stock head and prevents the tip of the ear from falling behind, even when the stock head does not protrude outward from the foot chain mechanism. With the structure that restrains the base of the plant without reinforcing it and directly delivers the stem culm from the foot chain mechanism to the stem culm processing device, it is possible to transport and supply the stem culm without disturbance while keeping it in a good intake posture. Good threshing and stem culm processing are conveniently carried out without any unhandled extremely short frames.

In the past, the stem culm processing device was arranged so that it could receive the stem culm directly from the end of the foot chain mechanism of the threshing machine, and its take-in roller was positioned perpendicular to the foot chain mechanism, so that the stem culm could be discharged easily. Since the supply is carried out through a shortened conveyance path and without changing direction, turbulence is further reduced, and the structure of the part attached to the stem and culm processing apparatus can be made extremely compact.

There are advantages such as
