Description

[Detailed description of the invention] This invention is a threshing device configured to install a waste straw processing device such as a cutter near the straw removal port and transfer and supply the waste straw group after threshing to this waste straw processing device for processing. This is related to the stem culm transfer device in the machine, and when threshing a group of stem culms, it can be kept in a posture suitable for threshing and transferred smoothly, and after threshing, the stem culm (excluded straw) group can be processed to remove straw. It is possible to continuously transfer and supply the straw to the equipment in an appropriate posture, and furthermore, even though the straw processing device is connected to the rear of the threshing machine, the overall longitudinal length can be shortened and the straw processing device can be installed high, which is advantageous. The purpose of this project is to provide a device that can.

The present invention will be explained in detail below with reference to the drawings of specific examples.

Although the drawing shows the case where the device of the present invention is implemented in the threshing machine 1 of a combine harvester C, the threshing machine 1 may be of any kind, such as a self-propelled threshing machine or a stationary threshing machine.

The combine C has a reaping transport section 4 mounted on the front part of a frame 3 supported by running rollers 2 so that the height above the ground can be changed, and a foot chain mechanism at the terminal end of a stock lifting mechanism 5 of the reaping transport section 4. Threshing machine 1 connecting the starting end of frame 3
The control device 7 is mounted on the side frame of the
and the engine 8 are mounted thereon.

The threshing machine 1 is installed with its handling barrel 9 facing in the direction of movement of the machine, and is configured in the form of a lower and upper chain. A port 11 is provided, and a straw discharge port 12 is provided on the rear side, and a straw disposal device 13 is installed in the rear cylinder portion adjacent to the straw discharge port 12.
However, in the case shown in the figure, the straw disposal device is installed with the upper part serving as an inlet, and the straw removal device is not a straw cutter in which a plurality of cutting blades are formed in parallel on the rotating shaft at appropriate intervals in the axial direction. ing.

A handling port is opened in the side wall of the handling chamber between the supply port 11 and the straw disposal port 12, and the waste straw processing device 1 is connected from the supply port 11 to the outside thereof.
The above-mentioned foot chain mechanism 6 is wound and installed over three parts, and the foot chain mechanism 6 is inclined so that the rear upper part is higher in a side view, and the upper part of the winding is higher than the lower part of the winding in a plan view. The foot chain 14 of the mechanism 6 is constructed such that the lower side of the winding is used as a transfer path, and a grip body 15 is disposed opposite to the transfer path. It is.

The gripping body 15 has a gripping rail 16, similar to the existing one.
It is formed by a clamping spring 17, a support member 18, etc., and includes a front clamping part 15a of the aforementioned foot chain 14 corresponding to the conveying action part 14a for threshing the stem culm group, and a straw group after threshing. The front gripping part 15a is divided into a rear gripping part 15b corresponding to the action part 14b that conveys S, and the front gripping part 15a is a third gripping part 15a.
As shown in FIGS. 3 and 4, the rear gripping portion 15b is installed offset to the outside of the foot chain 14, and the rear gripping portion 15b is positioned relative to the foot chain 14 as shown in FIGS. 3 and 5. It is installed offset to the inside.

Next, to explain the operation of the device of the present invention, the stem culm is pulled up by the reaping and conveying section 4, and is harvested and conveyed so that the tip of the stalk reaches the supply port 11 and the base of the stalk reaches the starting end of the foot chain mechanism 6. After that, the stalk part is held in a foot chain mechanism 6 and transferred in the direction of arrow A, while the tip part passes through the handling chamber 10 and is subjected to the threshing action by the handling cylinder 9. be.

During this threshing process, the front gripping portion 15a of the foot chain mechanism 6 holds the foot chain 1 as shown in FIG.
4, and the entire foot chain mechanism is inclined so that the culm side is lower in front view, and the rear part is higher in side view. Since the supply port 1
In the part near the starting end of the handling drum where grains are easily shed from the grain culm, the ears are kept in a downwardly tilted position to facilitate transfer, and in the rear part of the handling drum where grains that are difficult to shed must be removed. As the feed chain is tilted rearward and upward in side view, the tip of the ear is gradually pressed strongly against the handling barrel side to cause shedding, and the culm is separated as much as possible from the crimp net below to improve leakage efficiency. Once the grains are well ground, the grains are sloughed off.

When the stem culm group is transferred to the tube part where the threshing process ends, the stock base is gripped between the foot chain 14 and the rear gripping part 15b and the stem culm group is transferred again.
During this transfer process, the rear gripping portion 15b is positioned inwardly with respect to the foot chain 14 (see Fig. 5), so that the tip side is lifted upward and the entire stem culm (exhaust straw) is removed. The straw is transferred in a substantially horizontal position, and is opened and dropped into the intake port of the waste straw processing device 13 from the end of the transfer.

As explained above, the present invention has a straw outlet 12 of a threshing machine 1.
A waste straw processing device 13 is connected to the rear of the threshing machine 1, and the transfer end portion of the foot chain mechanism 6 of the threshing machine 1 is integrally extended to reach the waste straw processing device 13, and the husk is removed from the threshing machine 1. In this structure, the threshing machine 1 is constructed in the form of a lower and upper chain, and the foot chain mechanism 6 is connected to the handling barrel 9 in a side view. The gripping body of the foot chain mechanism 6 is inclined so that the rear part is higher with respect to the rotation axis of the foot chain, and the culm is gripped so that the sugar part is lower when viewed from the front. 14 threshing parts 1
4a, and a front gripping part 15a corresponding to the straw conveying part 1.
4b and a rear gripping part 15b corresponding to the foot chain, and the rear gripping part 15b is installed so as to be offset to the inside of the foot chain with respect to the front gripping part 15a which is offset to the outside of the foot chain. Since the rear grip part 15b lifts the shell culm in the horizontal direction and corrects its posture, when the shell culm receives the threshing action in the threshing machine section, its posture is adjusted to a proper downward tilted state. At the same time, the shell culm (exhausted straw) after threshing
The sugar portion is corrected for its downward tilting posture during threshing and the delayed transfer posture of the sugar part due to handling action, and is supplied to the waste straw processing device 13 in a good posture, and these series of transfers are carried out continuously by a foot chain mechanism. However, in the present invention, the gripping body corresponding to the foot chain is shifted in the direction of the culm of the shell. Not only that, but the threshing machine was made into a low-class upper chain type, and the entire foot chain mechanism was tilted so that the rear part was higher when viewed from the side, and the sugar culm portion was lower when viewed from the front, as if it were being gripped. Since the straw is organically assembled and controlled, it is not only possible to correct the straw expulsion posture by simply changing the position of the gripping body, but also to gradually remove the straw from the shell culm sugar part in the part where the threshing machine part has to release the remaining grains. is strongly pressed against the handling barrel side to perform strong threshing, while separating the grain culm from the lower crimp net to improve leakage efficiency, which has the remarkable effect of improving threshing processing performance and reducing load. It became something.

Furthermore, in the present invention, the foot chain mechanism is installed at an angle so that the rear side is higher when viewed from the side, so the overall front-to-back length is shortened while the straw disposal device is connected to the rear, and the straw disposal device is Since it can be installed with a high ground clearance, it has the advantage of being mounted on a combine harvester.
