Description

[Detailed description of the invention] (a) Industrial application field The present invention aims to improve the sorting performance of a threshing device mounted on a combine harvester.

(b) Prior art The technology of arranging an orthogonal processing cylinder perpendicular to the handling cylinder at the rear of the handling cylinder of a combine harvester is Utility Model Publication No. 53-23668.
There was something like the publication number.

However, the orthogonal processing cylinders in these conventional technologies differ from the conventional parallel processing cylinders in terms of sorting performance, simply because the parallel processing cylinder, which was conventionally placed parallel to the processing cylinder, is placed at the rear end of the processing cylinder. There isn't.

(c) Problems to be solved by the invention In contrast, the orthogonal processing cylinder of the present invention simply returns and processes the No. 2 processing material that has fallen onto the No. 2 conveyor, unlike the conventional method. Rather than returning it to the top, the chaff, straw waste, etc. discharged from the stroke rack at the end of the swinging sorting device are processed again and returned to the No. 2 conveyor. The aim is to further reduce this.

(d) Means for solving the problem In order to achieve the above objectives, the present invention is constructed as follows. Behind the oscillating sorting device 7,
In a threshing section provided with an orthogonal processing drum 3 perpendicular to the handling drum 1, the upper part of the processing chamber rotating plate 20 fixedly installed in front of the orthogonal processing drum 3 is located rearward on an approximately extension of the first flow grain plate 24. It is constructed so that it is tilted, and the lower part is visible above the No. 2 conveyor.

(e) Embodiments and operations The purpose and structure of the present invention are as described above. Next, the structure and operations of the embodiments will be explained based on the attached drawings.

FIG. 1 is a perspective view of the sorting device of the present invention. FIG. 2 is also a side sectional view. FIG. 3 is also a plan sectional view.
FIG. 4 is a rear sectional view as well. FIG. 5 is a plan view of the vicinity of the orthogonal processing cylinder. Figure 6 is also a rear view. FIG. 7 is an enlarged side sectional view of the vicinity of the orthogonal processing cylinder.

First, to explain the overall structure, the grain culm is raised by the pulling device of the combine and transported by the reaping and transporting device.
5, and the stock part passes through the handling chamber 26 while being held between the feed chains. At this time, the ears come into contact with the handling teeth 1a of the handling cylinder 1 and are shed, and the fine grains fall from the crimp net 5 onto the sorting plate 7a of the swinging sorting device 7. In addition, grains mixed with straw, chaff, etc. fall slowly from the crimp net, making it difficult for straw rack 7
placed on b. The fine grains falling from the stroke rack 7b and the fine grains sent from the sorting plate 7a pass through the sorting net or the sorting stroke rack 7c, and enter the first conveyor 8 from the first grain plate 24. The No. 1 conveyor 8 is connected to a grain frying conveyor, and fine grains are sent to a grain tank. In addition, the waste straw and the chaff and grains attached to it are transferred to the straw removal conveyor from the 4th port, and the straw waste and chaff that have fallen at the 4th port are transferred onto the stroke rack 7b of the swing sorting device 7 and the sieve wire 10. to fall. Conventionally, the straw waste and chaff sent from the oscillating sorter 7 to the sieving line 10 were discharged from the machine through the No. 3 port as is, except for those that fell onto the No. 2 conveyor section 9. The idea was to place the processing cylinder 3 orthogonally at the tip of this sieve line and above the No. 2 conveyor.
is provided, and the straw waste and chaff coming out of the third opening are processed again by the handling tooth 3a. When the grains are separated from straw waste, chaff, etc. by this process,
This grain falls from the concave 23 of the orthogonal processing cylinder 3 and enters the No. 2 conveyor 9. The second conveyor 9 is about to fall onto the first conveyor 8,
2 which is blown away by the wind of the sorting fan 6 and enters the second flow grain board 27 from the end of the first flow grain board 24
Collect the No. 2 grains and the No. 2 grains that have passed through the sieve line and fallen onto the No. 2 flow grain plate 27, and gather them to the right side of the threshing section.
As a result, the processing cylinder 1 is returned to the parallel processing cylinder 2 which is parallel to the processing cylinder 1. The grains processed by the handling teeth 2a of the parallel processing cylinder 2 fall again from the concave onto the swing sorting device 7, and the straw and culm that do not pass through the concave are transferred to the handling chamber 2.
Return to 6. In addition, a suction duct 18 is arranged above the orthogonal processing cylinder 3 over the entire width of the threshing section, and the suction duct 18 sucks up all the dust generated within the threshing section machine frame. By Juan 4,
The dust is blown out to the dust outlet 17.

In this overall configuration, the present invention concerns the position and shape of the processing chamber rotating plate 20 of the orthogonal processing cylinder 3.

As shown in FIGS. 4, 5, 6, and 7, the orthogonal processing cylinder 3 is equipped with handling teeth 3a, and the material to be processed is sent above these through a sieve line or the like. Injected. The shielding plate 2
1 and a processing chamber rotating plate 20, feeding plates 11 and 12 are arranged to be inclined in the direction of feeding the processed material to the third port. Further, a concave 23 is arranged at the lower part of the orthogonal processing cylinder 3, from which the grains threshed from the chaff enter the No. 2 conveyor. Further, a third port 22 for discharging straw waste and chaff after processing is provided at the left end of the orthogonal processing cylinder 3 toward the outside of the machine. The processing chamber of the orthogonal processing cylinder 3 is surrounded at the front by a dogleg-shaped processing chamber turning plate 20, and extended from this by a concave 23 at the bottom, and at the rear by a part of the second flow grain plate (rear) 28. The upper part is covered with a shielding plate 21 leading to the suction duct 18. The shielding plate 21 is tilted forward in an overhanging manner, and the processing material being processed inside the orthogonal processing cylinder 3 is splashed up.
It is configured so that it will not be sucked into the suction duct 18.

Further, the processing chamber rotating plate 20 is configured in a dogleg shape or an arc shape close to this, with the upper part being inclined rearward approximately on the extension of the first flow grain plate 24, and the lower part being orthogonal. It is bent along the outer periphery of the processing cylinder 3 and extends over the No. 2 conveyor 9 or into the concave 23.

In FIG. 2, 19 is a dust inlet at the end of the crimp net, A is the 4th inlet, and 32 is a dust guide plate.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

In other words, the processing chamber rotating plate provided on the extension of the first grain plate can separate the second processing material into those that fall onto the second flow grain plate of the second conveyor and those that enter the orthogonal processing cylinder. Since the upper part of this processing chamber rotating plate has an angle, it is possible to regulate the direction in which the processed material is released from the orthogonal processing cylinder.

That is, this has the effect of preventing the processed material in the orthogonal processing chamber from being thrown around by the handling teeth and flying out in the circumferential direction.
