Abstract

PROBLEM TO BE SOLVED: To provide the swinging sorter of a combine harvester capable of performing distribution supply by lead plates on upper and lower feed pans provided on the front part of a swinging sorting panel, leveling objects to be sorted and performing the sorting of a large volume with a narrow sorting width without sending dust to a rear part in a stripe shape. SOLUTION: A second reduction object is reduced to the front part of the swinging sorting panel 25 and supplied to an agitation processing barrel 30 at the front lower part of the swinging sorting panel 25 at the lower part of a second reduction port and the distribution supply is performed by the lead plates 28 and 29 on the upper and lower feed pans 26 and 27 arranged on the front part of the swinging sorting panel 25. Also, it is preferable to orthogonally cross the agitation processing barrel 30 with the axial center of a threshing barrel and to set it approximately to the width of a grain threshing part.

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, a reed valve is provided in the front part of an oscillating sorter so as to disperse the No. 2 reduction product (leveling of objects to be sorted at the front of the oscillating sorter) and to lift the No. 2 reduction product. A grain barrel provided with a processing cylinder is known.

[0003]

In the prior art described above, dust and untreated straw waste were re-shrunk by the treatment cylinder and then dispersed by the lead plate. There was a problem that the trail plate, which had been simultaneously released to the front part of the board, was not sufficiently and evenly dispersed, and it was difficult to obtain a sufficient effect.

[0004]

Therefore, according to the present invention, the No. 2 reduced product is not dropped directly on the front part of the rocking sorter, but the stirring process cylinder performs the grain-removing action while sending it laterally and swinging the sort. It enables sufficient diffusion in the width direction of the board, dust, straw dust, and grains are sorted, and the sorting width is effectively used to enable large-capacity sorting processing with a narrow sorting width.

It is configured so that it is possible.

It should be noted that the processing width of the stirring processing cylinder (30), that is, the working width, is provided so as to intersect the axis of the handling cylinder (6), and the discharge opening (50) is opposite to the second reduction cylinder (36). It is effective because it is provided on the side and the entire width can be used effectively and the objects to be sorted can be leveled effectively.

[0013]

As is apparent from the above embodiments, the present invention does not drop the No. 2 reduction product directly onto the feed pan (34) in front of the rocking sorter disc (32), but onto the stirring treatment cylinder (30). Unlike conventional reed valves, the dust is reliably distributed without being sent backwards, unlike conventional reed valves.
Achieves leveling of objects to be sorted, and agitating cylinder (30)
By making the width wide, the straw waste and the grain are agitated, and a large-capacity sorting process can be performed with a narrow sorting width by effectively utilizing the sorting width.
