Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wind sorting device for an oscillating sorter used in a grain processing plant or the like.

The wind sorting device of the conventional oscillating sorter removes bulky waste, powder, and other impurities mixed in with the grain by blowing air at a speed that can transport them, so the wind sorting device is relatively large. However, it has drawbacks such as high equipment costs and wasted air volume and electrical energy.

In order to resolve the above-mentioned disadvantages, the present invention has a large number of through holes for passing through the grains, and a grain receiving trough in which a large number of chevron-shaped veins are arranged is installed in the lower part 5 of the nine-hole wall sorting plate. By hanging and swinging integrally, large foreign substances such as bulky dirt mixed in with grains are discharged from the end of the rocking side plate by the operation of the porous rock sorting plate OII, and the grains, wood chips, and initial dust are removed. Small foreign substances such as A relatively small amount of air is ejected from the blowhole to separate and sort out the grains and contaminants due to the difference in specific gravity, thereby reducing the size of the blower as much as possible. The purpose of the present invention is to develop and provide a device that can reliably, smoothly, and quickly mass-produce high-quality selected grains by performing efficient wind selection.

The present invention will be explained with reference to embodiment figures. Figure center mark M(1)F
i A porous wall sorting plate with a large number of through holes (2...) that pass through the grains, and a large number of chevron veins (8...) at the bottom of the sorting plate (1).
...) are arranged to integrally form a sorting machine frame (5), and the sorting machine frame (5) is mounted on a gentle slope with the winding side raised higher. At the same time, abutment (6) K elastic support rod (7) (8
), and the machine frame (5) and crank (9) are connected by a rod (10) so that they can swing, and the sorting plate (1) Fi and a supply hopper ( A river is provided and straw waste is placed on the end of the swinging side plate of the sorting plate (1).
In addition to providing an outlet (12) for discharging bulky items such as bulky garbage,
A grain outlet (18) for discharging grains, small foreign objects, etc. is provided at the end of the swinging side plate of the receiving trough (4), and a blower port (14) is provided at the lower part of the outlet (18) to operate the air blower (+ , +1 r are connected, and a grain hopper (1

Because of the above configuration, in a preparation plant etc.
I Hiroshi/Large waste Raw material grain supply hopper (11) containing various flammable materials such as wood chips and dust
When the device is started, the raw material grains that have flowed down from the supply hopper (11) to the swinging side plate surface of the sorting plate (1) are transferred to the sorting plate (1).
) is moved laterally upward by the rocking action of the rocker, and the coarse foreign matter that gets mixed in is conveyed on the surface of the plate (1) and discharged from the coarse matter discharge port (12) provided at the end of the rocking side plate. The grains and fine foreign matter flow down into the hopper (17) for coarse foreign matter, and the grains and fine foreign matter pass through the numerous holes (2...) of the sorting plate (1) and enter the lower grain receiving trough (4). The grains and other food matter move in the shaking direction due to the shaking action of the receiving trough (4), and when they flow out from the grain outlet (18) provided at the end of the machine, they are The air blowing out from the blowhole (14) separates small foreign matter such as dust and wood particles with low specific gravity by flying through the hopper (17) for coarse foreign matter, and grains with high specific gravity flow down and become grains. Hopper = (16) K are separated, sorted, and discharged.

In this way, the wind sorting device of the oscillating sorter of the present invention has an air blower provided at the lower part of the grain outlet of the grain receiving trough and is connected to the air blower to remove coarse foreign matter and prevent it from entering the grains. Since small foreign objects such as wood chips and dust are sorted out by blowing air, compared to the conventional device mentioned above, the wind sorting device can be made as small as possible and the production cost is low. This has the effect of significantly saving electrical energy, increasing sorting efficiency, and achieving mass production of selected grains.
