Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to the structure of the sorting section of a self-propelled self-threshing device, a threshing device mounted on a combine harvester, etc.

(b) Prior art Conventionally, in self-propelled self-threshing equipment and combine harvester threshing equipment, a processing cylinder is provided parallel to the rear of the handling cylinder,
The sorting structure in which the filtrate after being processed and filtered in the processing cylinder is returned to the swinging sorting device located below the handling chamber via the grain board, and is then processed in the swinging sorting device. Such as No. 3567 of 1983 are known to the public.

(c) Problems that the invention aims to solve The purpose of the invention is to determine whether the grain culms to be threshed are uniformly sorted depending on the condition of the grains, and if they have been sufficiently processed, they can be returned as the second processed product. Continuing to return treated materials that do not need to be processed into the processing room may cause clogging of the processing room, or conversely, even after processing in the processing room, there are still adhered particles or unshelved particles that fall into the shaking sorter. However, there were problems such as fine grains coming out as loss in the third product coming out of the suction fan.

In particular, the filtrate after being processed in the processing barrel differs considerably due to the difference between rice and wheat, the difference in the difficulty of threshing, the difference in dryness in the field, etc.

The present invention utilizes these differences to optimize the filtrate from the processing chamber.

(d) Means for solving the problem The purpose of the present invention is as described above, and the configuration for achieving the purpose will be explained below.

In a threshing device in which a processing cylinder 6 is provided in parallel with a handling cylinder 7, a swing sorting device C is arranged below the processing cylinder 7, a second flow grain plate 17 is arranged below the processing cylinder 6, and the processing The flow grain plate 1 disposed below the barrel 6 is used to process the filtrate from the barrel 6 in the second processing section or the swing sorting device C.
It is configured to be switchable so that the flow can be selectively carried out.

(e) Embodiments and operations The purpose and configuration of the present invention are as described above, and the operations of the invention will be explained in conjunction with the configuration of the embodiment shown in the attached drawings.

FIG. 1 is an overall side view of the threshing device mounted on the self-propelled self-threshing device. FIG. 2 is a front perspective view of the sorting section of the threshing device. FIG. 3 is an enlarged side sectional view of the upper part of the threshing device.

In FIG. 1, the configuration of the self-propelled self-escape device will be explained.

A threshing device, an engine room 29, etc. are placed on a crawler-type traveling device 35. A pedestal is protruded to the left side of the threshing device, and the grain culms are collected on this pedestal and fed to the feed chain 25. The tip portion passes through the handling chamber A while being held between the feed chains 25, and the waste straw is sent in the direction of the straw removal chain. The threshed grains are sorted and fine grains are collected on the No. 1 conveyor 22, enter the storage tank 27 from the grain lifting cylinder 26, and are stored in grain bags on the bag holder 28.

An engine is arranged within the engine room 29.

The present invention relates to a processed filtrate in a processing cylinder 6 in a threshing device.

Figures 2 and 3 will be explained together.

The handling cylinder 7 rotates around the handling cylinder shaft 12, and forms a handling chamber A between the receiving net 13 and the handling chamber cover. A processing cylinder 6 is arranged parallel to the processing cylinder 7. 1
4 is a processing cylinder axis.

The processing chamber B and the handling chamber A are separated by a partition wall 18. Two openings are provided in the melting wall 18, one on the inlet side and the other on the outlet side. Reference numeral 18a denotes a return spout from the second thrower 20, into which the straw-mixed grains thrown up by the second thrower 20 are thrown into the handling chamber A. Further, 18b is a processing chamber opening, and materials such as straw waste produced in the handling chamber A that cannot pass through the receiving net 13 are thrown into the processing chamber B through this opening. In the processing chamber B, processing teeth are arranged so that the material to be processed is sent in the reverse direction from the exit side to the inlet side, and the grains adhering to straw are shed and the grains fall from the processing chamber receiving screen 15. A straw waste discharge port 15a is provided at the end of the process, and light waste discharged from this port is sent to a dust removal fan 8.
is absorbed and released.

The present invention makes the grain board 1 below the receiving screen 15 in the processing chamber rotatable around the rotation shaft 2, and transfers the filtrate from the receiving screen 15 onto the grain board 17a of the second conveyor 23. It is possible to switch between dropping the grains and dropping them onto the grain board 9 of the oscillating sorting device C.

A bellows 3 is installed at the front end of the grain board 1.
The structure is such that the flow of sorting air does not change.
Reference numerals 4 and 5 are contact plates for the grain flow plate 1 for switching.

The swinging sorting device C is supported by swinging links 30 and 31 and suspended at the lower part of the handling room receiving net 13.
The sorting plate 11, grain board 9, sorting net 10, etc. are integrated and oscillate. The fine grains falling from the sorting net 10 are sorted by the sorting wind from the sorting fan 19, fall onto the first flow grain plate 16a, and enter the first conveyor 22. The straw-mixed grains etc. blown away by the wind selection are transferred to the second flow grain board 1.
It falls onto 7a and enters the No. 2 conveyor 23. Then, it is returned to the handling room A from the second thrower 20.

Explaining the effect.

As shown in FIG. 1, when the grain grain board 1 is inclined toward the swinging sorting device, the filtrate from the processing chamber B reaches the grain selection screen 10 from the grain board 9 of the swinging sorting device C.
It mainly flows in the direction of the No. 1 conveyor 22. Therefore, in this case, in the case of rice varieties with good shedding properties, and in the case of grain culms that have been dried out, sorting is carried out in this direction.

Conversely, as shown in Fig. 3, the flow grain board 1 is replaced with the second flow grain board 17a.
In the case of tilting in the direction of
It reaches the number thrower 20 and is returned to the handling room A. This condition is used for wheat varieties with poor shedding properties and for grain culms that have not dried. In this embodiment, a processing cylinder is illustrated, but the same applies to a short cylinder called a straw removal cylinder.

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

First, depending on the conditions of the threshing material, for example, in the case of rice or wheat, the difficulty of threshing differs, the degree of dryness of grain culms and grains differs, etc. Depending on the conditions of the threshing material, it is mainly fed into a shaking sorter or it is recycled into a second stage. This makes it possible to clearly determine and switch between the two types, thereby optimizing the sorting conditions.

Second, by changing the grain flow plates, it is possible to obtain desired sorting, such as speeding up the processing to improve sorting efficiency, or slowing down the processing but improving sorting performance.
