Abstract

PROBLEM TO BE SOLVED: To enable effective utilization of a selection width of a swinging selection disk to level the material to be selected and enable the selection treatment of a large amount of the object. SOLUTION: A swinging selection disk placed under a tailing returning port 42 is provided with a vertically movable sieving wire 35 preferably driven independently of the selection disk. The sieving wire 35 is produced by bending a wire 35a having a round cross-section in U-form and each wire 35a is fixed to a sieving wire support 47 fixed to a swinging shaft 46 of the swinging selection disk at nearly equal intervals in the form of comb-tooth over the whole width of the swinging selection disk.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing selecting device for combine harvesters, and more particularly to a technique for leveling objects to be sorted so that the sorting width of the swing sorting plate can be effectively utilized.

[0002]

2. Description of the Related Art Conventionally, there has been a technique in which a reed valve is provided in the front part of an oscillating sorting board so as to disperse a No. 2 reduction product (leveling of objects to be sorted in front of the oscillating sorting board).

[0003]

The above-mentioned conventional technique has a problem that dust is sent in the form of streaks to the rear and is not evenly dispersed, and it is difficult to obtain a sufficient effect.

[0004]

Therefore, according to the present invention, the No. 2 reduction product is not dropped directly on the front part of the rocking sorter, but is treated with a sieving line to remove the reduced product from the feed pan in the front part of the rocker sorter. Dust can be dispersed to the subsequent chaff sieve, and the sieving action of the sieving line sorts out dust, straw dust, and grains, and effectively uses the sorting width to enable large-capacity sorting with a narrow sorting width. And

The sorting wind from the Karato (39) is separately applied to the grains and dust falling from it to stabilize the sorting performance. Further, by the upper and lower sieving action of the sieving line (35), it is possible to promote the dispersion of grains, dust and straw waste in the rear feed pan (34) and chaff sieve (36), and above the sieving line (35). The reduction port (42a) of the No. 2 reduction conveyor (42) is faced to disperse the No. 2 reduced product so that a large amount of grain can be effectively treated within the limited sorting width. It is configured in.

The sieve line (35) is connected to the second reduction port (42
a) With a gradient in the left-right direction so that the right side is slightly higher, the No. 2 reduced product is fed to the left side of the machine, the full width of the sieving line (35) can be effectively used, and the product to be sorted is selected. This is effective because it can be effectively leveled.

[0013]

As is apparent from the above embodiments, the present invention does not drop the No. 2 reduced product directly on the feed pan (34) in front of the rocking sorting board (32), but by using the sieving line (35). Unlike the conventional reed valve, the treatment ensures that the dust is not streaked and is not sent to the rear, and that the dust is reliably dispersed, the leveling of the objects to be sorted is achieved, and the sieving line ( Dust, straw dust, and grains are sorted by the upper and lower sieving action of 35), and a large-capacity sorting process can be performed with a narrow sorting width by effectively utilizing the sorting width.
