Description

[Detailed Description of the Invention] The present invention relates to a second processing device in a threshing machine.

In other words, a swinging sorter equipped with a chaf sieve/grain sieve and a sieving wire or a stroke rack is installed from the bottom of the handling room to the dust exhaust side,
In a threshing machine configured with a No. 2 spiral conveyor installed horizontally below the sieve line or straw rack, the second grains received from the No. 2 spiral conveyor and thrown up by a thrower are sorted by a screen barrel, and grains, etc. The second processing can be carried out reliably by distributing the straw waste to the grain sieve side, and the straw waste to the sieve line or straw rack side. To provide a system that enables smooth sorting processing without causing clogging, and that can be suitably implemented with a simple structure.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a sectional view of a threshing machine mounted on a combine harvester. A supply port 10 and a straw discharge port 11 are formed at both lower end sides of a handling chamber 4 in which a handling barrel 9 with handling teeth 8 is installed. A crimp net 12 is stretched on the lower side of the chamber, and a downward dust inlet 13 is formed at the end of the straw discharging side. Sorting and dust removal chamber 1 with
6 and is constructed in the same manner as the conventional structure.

In addition, the swinging sorter A, which extends from the bottom of the handling chamber 4 to the sorting and dust removal chamber 16, is equipped with a chaff sieve 1 and a grain sieve 2 above and below the middle part, and a sieve wire 3 on the tip side. A pressure-type cross-flow fan 17 is installed below one end of the body A, and a No. 1 helical conveyor 19 is installed in the No. 1 gutter 18 installed under the grain sieve 2. A No. 2 spiral conveyor 5 is mounted on the No. 2 gutter 20 provided below, and the structure is similar to that of the conventional structure.

A second processing chamber 22 is formed on the side of the treatment chamber 4 opposite to the side of the feed chain 21, and a mesh cylinder B is mounted in the chamber 22. A net 24 is stretched around the outer periphery between 23 and 23, and is mounted on a shaft so as to be rotated by input from an input pulley 26 at the end of a shaft 25 inserted into the net trunk B. A brush 28 supported by a support body 27 is brought into contact with the upper part of the thrower C, and the tip discharge port 6 of the thrower C is connected to the terminal end side of the No. 2 spiral conveyor 5.
are installed on the outer surface of the net 24 so as to face each other and approach each other with a small distance between them.

In addition, a grain grain board 29 is provided diagonally from the bottom of the second processing chamber 22 to the upper side of the swing sorting body A, and on the upper surface of the grain grain board 29 and below the mesh barrel B, a guide body 7 is provided. is installed, but one surface 7a of the guide body 7
is formed so as to face downward on one side of the mesh body B, which is the side of the discharge port 6, and is inclined so as to guide the straw waste to the side of the sieve line 3; The surface 7b is formed so as to be able to guide the grains falling from the net barrel B to the chaff sheave 1 side.

Therefore, during the work, the screen barrel B rotates as shown by arrow A, and the second material that is oscillatedly sorted by the oscillating sorter A and falls from the sieving line 3 is conveyed by the second spiral conveyor 5. At the point where it is thrown up by the thrower C, the net body B is
The grains in the second grain discharged onto the outer circumferential surface of the guide body 7 pass through the net 24 as shown by the arrow B, and leak from the net 24 as shown by the arrow C.
It flows down onto the chaff sieve 1 while being partitioned by the surface 7b, and is sorted together with the sorted materials falling from the handling chamber 4.

In addition, straw waste that is discharged from the discharge port 6 of the thrower C and falls without passing through the screen 24 is guided by the surface 7a of the guide body 7 and falls onto the sieve line 3 as shown by arrow D. Then, it is sorted as it is by the sieving wire 3 and the sorting air.

A brush 28 is provided in contact with the upper portion of the mesh cylinder B to prevent the mesh 24 from becoming clogged.

In this way, the present invention has a swinging sorter equipped with a chaf sieve/grain sieve and a sieve wire or a stroke rack extending from the bottom of the handling chamber to the dust removal side, and a second helix installed below the sieve wire or the stroke rack. In a threshing machine configured with a conveyor installed horizontally, a net drum is rotatably mounted on a shaft on the side of the handling chamber, and the tip discharge port of the thrower that communicates with the No. 2 spiral conveyor is attached to the outer peripheral surface of the net drum. A guide body is placed below the net barrel so that the paddy passing through the net barrel is guided to the upper side of the chaff sheave, and the straw waste falling from the outer peripheral surface of the net barrel is guided to fall to the sieve line or the straw rack side. Since it is installed on the side, the second material is received from the No. 2 spiral conveyor and thrown up by the straw, and released onto the circumference of the rotating mesh barrel. It can be distributed to the line or stroke rack side, and the second processing can be carried out reliably and well, and there is no need to return rice to the processing cylinder or handling cylinder side, causing rice removal or clogging, as in the past. It has the advantage of being able to carry out a smooth sorting process and can be suitably implemented with a simple structure.
