Description

[Detailed Description of the Invention] The present invention relates to a culm conveying device in a threshing device of a combine harvester.

Headland harvesting and rice handling work, which is done by hand or by using a binder before harvesting with a combine harvester, are very necessary, and generally speaking, handling of rice on headlands is also done by hand-harvesting with a combine harvester. It is usually done in one's own opinion.

In this case, the handled rice is not transported sequentially from the reaping section and put into the threshing device, but is processed by feeding it into the foot chain at the inlet A of the handling drum.

However, if there is a clamping device at the starting end of the foot chain as in normal combine harvester work, the culm cannot be easily gripped by the circular pipe, so when cutting corners, a clamping device corresponding to the starting end of the foot chain is used. The most advanced method is to retract the clamping device to facilitate manual handling and supply of the culm. It makes it convenient.

However, this type of conventional device has a structure in which a rotary scraping device is specially installed at the starting end of the foot chain, or a clamping body is installed that approaches or moves away from the starting end of the foot chain by fanning. The former has a very complex structure and is problematic in practice, and the latter has a starting end clamping body that is moved far away from the foot chain.
Although a space is created that facilitates the handling and supply of shell culms, there is a problem in that it is not easy to feed the shell culms because it must be done directly by the clamping force dog of the clamping device. It is happening.

Therefore, the present invention has an extremely simple structure, and while the switching operation can be easily performed in conjunction with the reaping latch, it is also possible to easily supply the culm to the starting end of the foot chain when cutting corners. The present invention aims to solve the conventional problems by providing a device in which the culm can be easily inserted between the foot chain and the clamping device.

Next, the embodiment shown in the drawings will be described in detail. FIG. 1 shows a side view of a combine harvester according to the present invention, with crawler 2
A reaping frame support frame 34 is fixed to the front end of the machine frame 22 supported by
The machine is equipped with a threshing device 31 having a foot chain 11 and a control tube 26 and a nut 33 at the front right side of the body, and a paddy receiving section at the rear thereof.

Additionally, there is a grass dividing board 2 at the frontmost part in front of the threshing device 31.
4 will be placed.

Reaping frame 34 in the front and back direction that supports each of the grass dividing boards
A cutting blade 35 is installed behind the grass dividing board.

Further, a pair of lifting cases 25 each having tines are installed diagonally behind the grass dividing board, and two pairs of star wheels 32 are installed side by side so that the front portions of each are positioned above the cutting blades 35. , from above both star wheels toward the front and outward,
The auxiliary conveyance bodies 36 of belts with protrusions are extended in a rectangular shape, and a lower conveyance chain 29 is installed diagonally from the rear upper part of both star wheels 32, and a transfer chain 17 is further installed between the foot chain 11. It will be set up.

In a combine harvester having such a general configuration, the present invention, as shown in an enlarged view in FIG. It is configured in body 1.

A horizontal rod 5 is fixed to the base of the clamping body 1, and the horizontal rod 5
is bridged between long holes 6 and 7 formed between the clamping devices 4 and 4a, respectively, so that the entire clamping body 1 moves forward and backward as the horizontal rod slides within the long holes. Then, the long hole 6,
When the horizontal rod is located at the rear end of 7, it retracts along the conveyance direction as in the position 1' in FIG. While leaving a slight working part, the front part of the starting end of the foot chain is positioned with a gap between it and the starting end of the foot chain.

Accordingly, in the embodiment shown in FIGS. 2 and 3, the clamping body 1 is a thrust ammunition 2 which is interposed by locking the ends of the clamping body 1 and clamping devices 4 and 4a, respectively. The clamping body itself, which includes the horizontal rod 5, is connected to one end of the push-pull wire 8, which is connected to the clutch operating lever 19. By pushing and pulling the wire 8, the engagement position between the horizontal rod 5 and the elongated hole 6.7 can be changed and fixed.

Furthermore, in the embodiment shown in FIGS. 1 and 4, the bullet for connecting and disconnecting the clamping body 1 to the link of the foot chain 11 is used as a tension bullet 3 to pass through the base of the shell culm 14. In order to avoid any problem, the ammunition holding frames 12 and 13 extended correspondingly from the foot chain fixing frame 20 and the clamping body 1 are locked and added to draw the clamping body 1 toward the foot chain.

One end of the push-pull wire 8, which is connected to the clutch operating lever 19, is connected to the clamping body as in the embodiment shown in FIGS. 2 and 3, and the push-pull operation of the wire 8 is Therefore, the engagement position between the horizontal rod 5 and the elongated hole 6.degree. 7 can be changed so that they can be fixed.

Among them, 15.16 is the foot chain guide roller 1
8 is the guide rod of the inheritance chino, 21 is the travel control lever 28
9 and 10 are push-pull wire outer and fixing fittings; 4c;

4b is a constituent member of the shell culm holding device.

Next, the operation of the apparatus configured as described above will be explained.

Whether it is the embodiment shown in Figures 2 and 3 (when the ammunition is a tension ammunition) or the embodiment shown in Figures 1 and 4 (when the ammunition is a tension ammunition), the reaping clutch lever 19
is operated to the "on" position, the push-pull wire 8 connected to the lever 19 pushes the clamping body 1 and moves the horizontal rod 5 to the front end of the elongated holes 6, 7 and fixes it. , the clamping body 1 is normally maintained in the conveying position for combine harvesting work, as in the solid line position in Figure 2 and the position shown in Figure 1, and is brought into elastic contact with the foot chain 11 side by the ammunition machine 2 or 3. .

Therefore, the stock part of the culm transferred by the inheritance chain 17 during the combine harvesting operation is sent between the clamping body 1 in the normal position and the starting end of the foot chain, and is transferred from the rotating part to the foot chain 11. The grain is transferred to the clamping and conveying section by the clamping device 4 and is threshed and supplied.

If you want to take care of the culm that has been harvested in advance, operate the reaping latch operating lever 19 to the "off" position, and the push-pull wire 8 connected to this operation will move the transverse rod 5 into the elongated hole 6. , 7 is moved to the rear end of the long hole and fixed, so the clamping body 1 is moved back to the retracted position O, leaving a slight clamping action part between it and the foot chain, and the starting end of the foot chain is opened. becomes.

When the clamping body 1 moves in and out, whether the ammunition is a thrust ammunition 2 or a tension bullet, the ammunition is locked to the clamping body using the clamping device side locking part as a fulcrum. Since the parts move as the gripping body moves, the weight moves in and out with a pressing effect on the foot chain side.

Therefore, if a carelessly supplied shell culm stock base is supplied to the opened foot chain starting end with the clamping body 1 retracted, the shell culm can be easily attached to the clamping action part at the retracted position. After that, the husks can be threshed using the transfer action of the foot chain, just like in normal combine harvester operations.

Since the present invention is configured and operates as explained above, the structure is significantly simpler than the conventional one, and the operation in conjunction with the reaping clutch can be performed simply and easily. Moreover, when cutting corners, it is possible to easily feed the shell culm to the starting end of the foot chain and feed the supplied shell culm into the circular pipe without difficulty, eliminating the problems that occurred with conventional equipment. It became a thing.
