Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guide clamp and transfer device for cut husk culms in a combine harvester.

That is, in a combine harvester configured by supporting a lower conveyor cheno extending from the lower part of one of both star wheels for scraping culms so as to slide along the side of a support guide extending rearward, The culm to be harvested is provided so that it is caught in both star foils and transferred to a lower conveying chino, and is guided and conveyed in a pinched manner without twisting.

That is, the conventional system is equipped with a star foil and a conveying device, and in order to prevent the shell culm from being turned around when scraped by the star foil, the clamping rod of the conveying cheno is extended above or below the star foil. This is a known technique, but in this case, it is scraped with star foil! A part of the base of the shell culm to be transported is supported by a conveyor cheno and a lever, and since there needs to be a space between the top and bottom of the star foil and the conveyor chano, it is supported by a conveyor cheno and a cross-bar. Even in a state where the star foil rotates, the upper part of the base of the culm, which is supported by the rotation of the star foil, is naturally pulled in the direction of rotation, resulting in the disadvantage that it may be pulled out or transported with the base not aligned. .

In view of this drawback of the joint, the present invention has been devised to eliminate the above-mentioned drawback by disposing a thin bar-shaped support rod between the star foil and the upper link of the conveyor chino.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a schematic side view of a combine harvester, in which a shell culm device 4 is mounted on a machine stand 3 supported by a traveling body 2, and a reaping and conveying device is installed in front of it. The box 5 is configured to be freely raised and lowered by a hydraulic device 6 as a rotational center, and a riding type control device 7 is disposed on the right side of the device.

In addition, in the reaping and conveying device, a grass divider 8 is installed in the front, a pulling device 9 is installed behind it, and a cutting blade 11 is installed in the rear lower part of the device 9 in a lateral direction astride a reaping frame 10. .

A transmission case portion 12 is provided behind the cutting blade 11, and drive shafts 13 each extend upward from the case portion 12.
A star foil 1.1' for scraping the culm is attached to the upper part of the culm 13', and both star foils 1 and 1' are arranged side by side in the horizontal direction and mesh with each other in reverse directions in the directions of arrows A and B. A sprocket 15 is supported via a bracket 14 at the rear of a support guide body a made of a plate that extends from the rear lower part of the star wheel 1 toward the rear of the aircraft body, and supports a lower conveyor chain A that is wrapped around the sprocket 15. The star wheel 1 is hooked around the sprocket 16 below the guide body a, but the pin A3 straddles the link parts AI and A2 on both sides of the cheno A against the rail part al bent on the side surface of the support guide a. A support lever 1T, which is provided so as to slide on the rail part ai and rotate, and is connected to the upper surface of the support guide a, is inserted into an engaging body 19 fixed to the frame 18 of the reaping and conveying device, The support lever 17 is engaged with a large number of engagement grooves 20 in the vertical direction in the engagement body 19 to adjust it up and down, and both star wheels 1, 1' are moved around a pivot point below both star wheels 1.1'.
, the support guide body a, and the chino A are all configured so that the inclination can be adjusted on the side.

Further, a U-shaped support rod 21 extends from below the support guide a to support the support frame 22, while a support frame 24 is supported by the lower frame 23 of the star foil 1', and both support frames 24
, 24 are interposed with ammunition 25, 25, and support rods 26, 26 are inserted therein, and the tips of both support rods 26, 26 are fixed to a long round rod B, and the rods The rod B is installed opposite to the chain A, and the part of the special rod B between the rear of the meshing position l\ of both star wheels 1 and 1' and the terminal end 2 of the clamping part is connected to the link parts AI and A2 in the chain A. The front part of the clamping rod B is moved from the rearward position to the engagement position to the bending guide part that bends and extends forward and outward along the lower part of the star foil 1'. to form.

The bent front end C1 of the thin bar-shaped support rod C is fixed by welding to the upper surface of the part of the pincer B that extends toward the engagement position, and the entire support rod C is aligned above the pinion rod B and engaged. The support rod C is extended at the rear end to the position and the rear end C2 is the free end, but the support rod C is connected to the link part A of the chain A from the middle.
1. Approach the top and extend it as shown.

Note that the upper conveyor tine 27 is located above the lower conveyor chino A.
, and a transfer cheno 29 is constructed by extending from the rear upper part of the cheno A toward the foot chain '28 of the threshing device 4.

Therefore, in combine harvester work, as the machine moves forward, the planted culm that has been divided by the weed cutting body 8 and pulled up by the pulling device 9 is cut by the cutting blade 11.
The star wheels 1 and 1', which rotate in the opposite direction in the direction A, are scraped between them, and the culm part is fed between the cheno A and the pinning rod B from the engagement position C, and is pressed against the peg. Cable B
While sliding, it is transferred by Cheno A and sent to the end two side.

In that case, the culm part of the shell culm that is scraped by the star foil 1' toward the meshing position C is guided without being disturbed by the bending guide section that bends and extends downward from the star foil 1', and The culm part sent from S to the chain B side is actively guided to the chain A side by the guide of the lever B, and is prevented from being wrapped around the star foil 1'III.

The support rod C extending from the part of the housing to the interlocking position extends along the upper part of the pinion rod B, so that the culm flowing through that part is not disturbed while cooperating with the pinion rod B. In addition to supporting and guiding the chain A side, it also supports the chain A from above to prevent it from derailing from the rail section ai of the support guide body a by pressing the button when the flow is intermittently or after reaping. be able to.

The carcass and head side are conveyed by the upper conveying tine 2T, and the culm side is transferred from the chain A to the transfer chain 29, and further to the foot chain 28, where it is supplied to the threshing device 4.

Further, the support lever IT can be moved up and down with respect to the engaging body 19 to support it, and the inclination of the entire star foils 1, 1', chain A, etc. can be adjusted, so that conveyance and supply can be carried out according to the length of the culm.

In this way, the present invention has two star foils 1 for scraping the culm,
Lower conveyance chino A extending from the lower part of one side buttoned at 1'
In this combine harvester, a link portion AI of the lower conveying cheno A corresponds to a culm holding portion of the lower conveying cheno A. .

A link portion A1 is located between the star foils 1, 1' and the lower conveying machine at a portion of the clamping rod B extending between A2 and extending to support the star foils 1, 1' in an engaging position.
Move the thin bar-shaped support rod C toward the upper position and move it backwards 1 to the engaged position.
Since the culm part flowing through that part is completely prevented from being wrapped around the star foils 1 and 1', the culm part that is fed from the meshing position C to the chain B side is The clamping rod B and the supporting rod C work together to actively support and guide the chain B side.

Moreover, even when the flow is intermittently, the support rods C are present, so that the support rods B can reliably support the conveyance without derailing downward.
