Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a threshing control device for a self-threshing type threshing machine mounted on a combine harvester, a harvester, or the like.

(b) Conventional technology Conventionally, a straw cutting sickle was installed on the inner periphery of the handling chamber, and a partition plate was placed near the end of the handling chamber to subdivide the long straw, ear cuts, etc. that were carried around by the handling teeth of the handling barrel. A threshing machine is already known which performs a chemical treatment or a threshing process and prevents straw waste from passing over the partition plate to the dust inlet, thereby allowing the straw waste to remain in the handling chamber.

(c) Problems to be solved by the invention The known threshing machine simply handles the long straw and ear scraps generated in the handling chamber with its handling teeth and divides or threshes them with a straw-cutting sickle. I couldn't process it.

In particular, if only a partition plate was provided near the end of the handling chamber, straw waste and the like would pass over the partition plate and migrate to the dust inlet, which would be discharged into the sorting section, resulting in a decrease in sorting performance.

(d) Means for solving the problem The present invention is to attach a straw cutting sickle to the inner periphery of a handling chamber in which the handling cylinder is mounted on an axis, and to install a partition plate near the end of the handling chamber so that In a threshing machine with a dust outlet on the lower side in the grain culm movement direction, a straw cutting sickle is provided at a part spaced apart from the partition plate to the upper side in the grain culm movement direction, and the straw cutting sickle is provided on the upper side in the movement direction from the partition plate and A guide plate inclined in the opposite direction to the grain culm movement direction is provided on the upper side in the rotational direction of the handling barrel so as to guide the straw waste toward the straw cutting sickle, and the straw waste is returned in the opposite direction to the grain culm movement direction. The above-mentioned problems were solved by guiding the cutting process and reprocessing using the handling teeth of the handling cylinder.

(e) Function: Grain culms are fed to the threshing machine and the grains generated in the handling room are dropped from the receiving net to the swinging sorter located below the receiving net and are sorted, as in the conventional system. The long straw and ear fragments are carried around by the handling teeth and are finely divided or sloughed by the straw cutting sickle, and near the end of the handling chamber, the straw waste and ear fragments cross over the partition plate and move to the dust inlet. I will try.

At this time, the long straw, ear cuts, etc. that are carried along the plate surface on the supply port side of the partition plate are received by the guide plate and guided towards the straw cutting sickle, and the straw is cut off before crossing the partition plate. The particles are reliably fragmented or shed with a sickle, and then passed through the partition plate and transferred to the dust inlet for discharge.

(F) Example The example shown in the drawings is explained below.1
is a handling cylinder that is mounted on a shaft in the handling room 2, and a swinging sorting body 5 is installed from the bottom of the receiving net 3 to the dust sorting chamber 4, and the lower sorting path is connected to the receiving net 3. A transfer flow plate 6 facing downward, a sorting net 8 connected to the end thereof and facing above the first receiving gutter 7, and a screening net 8 extending above the first flow plate 10 and extending above the second receiving gutter 9. The upper sorting path is composed of a transfer plate 13 that receives and transfers long straw, ear cuttings, etc. discharged from the dust inlet 12, and a transfer plate 13 that is extended to the transfer plate 13 and is connected to a suction windmill 14. Directional stroke rack 15
It is made up of.

Further, the air blower 16 provided below the starting end of the handling chamber 2 is connected to the sorting net 8 and the upper stroke rack 1.

In addition, a plurality of straw-cutting sickles 18 are attached to the upper part of the suction port 2a side of the handling chamber 2 (the lower part in the case of a bottom-handling type threshing machine) and the back side, and the straw-cutting sickles 18 are installed near the end of the handling chamber 2 and the dust is sent. The mouth 12 is a partition plate 19 extending from the bottom of the suction mouth 2a to a part corresponding to the straw-cutting sickle 18 on the back side, a partition plate 21 fixed to the lower surface of the threshing plate 20, and the handling opening 2a.
It is partitioned off by a partition plate 22 at the top of the screen.

A partition plate 22 above the suction port 2a
As shown in FIG. 4, a guide plate 23 is rotatably mounted on the side of the supply port side with a hinge 24, and this guide plate 23 is attached to the straw cutting sickle 18 in the vicinity as shown in FIG. 4b. The lower end faces the straw cutting sickle 18, and the guide plate 2
The mounting plate 25 welded to the upper outer surface of the guide plate 23 has a fixing nut 26 on the inner surface, and is fastened with a bolt 29 inserted from the outside of a long hole 28 drilled in the handling chamber side plate 27. The angle of the guide plate 23 is made wider than the length of the straw cutting sickle 18 so that it can receive more straw waste, etc.
The lower part is narrow for better cutting.

In the above-mentioned device, small straw waste and grains from the threshed grain generated in the handling room 2 fall from the receiving net 3 into the transfer flow plate 6 of the oscillating sorter 5 and are transferred to the sorting net 8. Here, the straw waste is blown away by the main sorting wind and removed, the grains leak and flow into the first receiving trough 7, and the straw waste including the second one remaining on the screen is transferred to the transfer plate 11.
a to the stroke rack 11 for further sorting, and the second material falls into the second receiving gutter 9 and is returned to the transfer flow plate 6 or the handling chamber 2 by the second transfer spiral and the second thrower 31. Ru.

While the long straw and ear cuts during threshing are carried around by the handling teeth 1a of the handling barrel 1, the straw cutting sickle 18...
When the grains are shredded or shredded and moved toward the end of the handling chamber 2, the partition plates 19, 21, 2
2, the movement is suppressed by the threshing plate 20, and when it goes to the suction port 2a through the lower part of the threshing plate 20, it is caught by the guide plate 23 which is inclined toward the upper side in the direction of movement of the grain culm, and is guided back to the upper side, and then the straw is cut. It is cut by the sickle 18, and then subjected to finer processing and shedding processing by the handling teeth of the handling cylinder 1.

The straw waste, ear cuts, etc. that have undergone such treatment are discharged from the dust inlet 12 onto the corrugated transfer plate 13 over the partition plates 19, 21, and 22, and are discharged onto the corrugated transfer plate 13.
The material to be sorted is sieved while being oscillated by the stroke rack 15, and the second material that has leaked out joins the material to be sorted transferred by the lower transfer plate 11a and the stroke rack 11, etc., and is sieved again. sieved,
The straw waste transferred by the stroke racks 11 and 15 is sucked and discharged outside the machine by a suction windmill 14.

(g) Effects of the invention In this invention, a straw-cutting sickle 18 is attached to the inner periphery of the handling chamber 2 in which the handling barrel 1 is mounted on an axis, and a partition plate is provided near the end of the handling chamber 2, and the grain is removed from the partition plate. In a threshing machine in which the dust inlet 12 is provided on the lower side in the direction of movement of the grain culm, a straw-cutting sickle 18 is provided at a portion spaced apart from the partition plate toward the upper side in the direction of movement of the grain culm, and In addition, a guide plate 23 is provided on the upper side in the rotational direction of the handling barrel and is inclined in the opposite direction to the grain culm movement direction so as to guide the straw waste toward the straw cutting sickle 18. Since the structure is configured so that grains are guided back in the direction and cut and then reprocessed by the handling teeth of the handling barrel 1, long straw and ears are removed from the threshed grains generated in the handling chamber 2 by threshing the grain culms. The chips, etc. are carried around by the handling teeth and subjected to fragmentation and shedding processing by the straw-cutting sickle 18, and before they move to the end of the handling chamber 2 and cross the partition plate, the guide plate 23 The straw, etc. is received and guided back toward the straw cutting sickle 18 in the opposite direction to the grain culm movement direction, and the straw cutting sickle 18 makes it possible to perform sufficient shredding treatment again, and this fragmentation The processed cuttings can be carried around further by the handling teeth and subjected to fragmentation and shedding treatment, so that straw waste remains as long straw or ears of ears that have not been adequately sheared are transferred to the dust inlet 12. It is possible to prevent the waste from being discharged, thereby improving the sorting performance.
