Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wind sorting device for an oscillating sorter used in processes such as grain preparation plants.

The wind sorting device of the conventional oscillating sorter removes large and small contaminants such as bulky dirt and dust mixed into the grain by blowing air at a wind speed that can be transported, so the wind sorting device is relatively large. However, it has drawbacks such as high equipment cost and waste of air volume and electrical energy.

In order to solve the above-mentioned drawbacks, the present invention has a porous wall sorting plate provided with a large number of through holes through which the grains pass, and is mounted in an inclined manner with the swinging side elevated. In a sorting device that is equipped with a vibrating conveyor arranged with chevron veins and swings integrally, a grain discharge port provided at the end of the swinging side plate of the conveyor is connected to a porous wall flow grain plate, and By connecting the plate surface of the plate to a ventilation device, coarse foreign matter such as bulky dirt and straw debris mixed in with the grains can be removed by porous holes (exhaust holes provided on the side of the plate surface on the shaking side by the swinging action of the sorting plate). At the same time as being discharged from the outlet, grains and small impurities such as heather and dust fall through the holes in the sorting plate onto the vibrating conveyor at the bottom, and the straw is removed by the shaking motion of the conveyor at the end of the shaking side plate. In the process of flowing from the grain discharge port to the porous wall flow grain plate and flowing to the discharge side, impurities mixed in the grain are screened out by wind that is blown from below to above the porous wall surface from the ventilation device at the bottom. Therefore, we aim to reduce the size of the ventilation equipment as much as possible, and create equipment that performs high-efficiency wind selection to reliably, smoothly, and quickly mass-produce selected grains of high quality. We plan to develop and provide this service.

The present invention will be explained with reference to embodiment figures. The reference numeral (1) in the figure is a porous wall sorting plate provided with a large number of through holes (2...) that pass through the grains, and the lower part of the sorting plate (1) has a large number of chevron veins (8...).
) are arranged and a nine-vibrating conveyor (4) is provided to integrally form a sorting machine frame (5), and the shaking side of the sorting machine frame (5) is raised and mounted in a gentle slope. , elastic support rods (7) (
8), and the machine frame (5) and crank (9) are connected by a rod (10) so as to swing, and the sorting plate (1) has a supply hopper on the swinging side plate surface. (11) A large material discharge port (12) for straw waste, bulky garbage, etc. is provided on the side of the swinging side plate surface of the sorting plate (1), and a large material discharge port (12) is provided at the end of the swinging side plate of the conveyor (4). A grain discharge port (18) for grains, fine foreign matter, etc. is provided, the discharge port (13) is connected to a porous wall flow grain plate (14), and a ventilation device is provided on the plate surface of the flow grain board (14). (15) to form a vertical wind tunnel section (16), and (17) is connected to the wind tunnel section (16).
(18) is the exhaust pipe, (19) is the guide wall for flowing the sorted coarse impurities to the discharge port (12), (20) is the discharge valve of the supply hopper. .

Because of the above-mentioned configuration, the raw material grains are mixed with various impurities such as straw, bulky waste, wood chips, and dust at a night-making plant and fed to the supply potper (11), and the equipment is When started, the sorting plate (
The raw grains that have flowed down to the rocking side plate surface of 1) are sorted by the sorting plate (1).
The coarse foreign matter is moved in the rocking direction by the rocking action of the rocker, and the mixed coarse foreign matter is conveyed on the plate (1) surface and passes through the guide wall (19) to the coarse foreign matter discharge port provided on the side of the rocking side plate surface. (12) to the outside of the machine, and grains and fine impurities are discharged from the sorting plate (12).
)O pass through numerous through holes (2...) and accumulate on the lower vibrating conveyor (4), and the falling objects such as grains are moved in the shaking direction by the shaking motion of the conveyor (4). In the process of flowing grain from the grain discharge port (18) provided at the end of the machine to the porous wall flow grain plate (14) and flowing to the discharge side, the lower ventilation device (1
5) to the grain board (14) O. The grain is sorted by specific gravity by the wind that blows from below to above on the porous wall surface, and small impurities such as dust and wood chips with low specific gravity are blown up inside the wind tunnel part (16) and sent to the upper part. The grains with a high specific gravity flow down the flow plate (14) and are sorted out, and are taken out of the machine from the grain ejector (17) in the wind tunnel section (16). be done.

As described above, the wind sorting device of the rocking sorter of the present invention has a porous wall sorting plate provided with a large number of holes through which grains pass, and is mounted in an inclined manner with the rocking upper side elevated. In a sorting device that is equipped with a vibrating conveyor having a large number of chevron-shaped veins arranged at the bottom and swings integrally, a grain discharge port provided at the end of the swinging side plate of the conveyor is connected to a porous wall flow grain plate, and , the lower surface of the flow grain board is connected to a ventilation device, and fine foreign matter such as wood chips and dust mixed in the grains from which coarse foreign matter has been removed by the upper porous wall sorting plate is blown onto the surface of the perforated flow grain board. Since it uses air to sort, compared to the conventional equipment mentioned above, the wind sorting equipment can be made as small as possible, the production costs are low, and the amount of air and electrical energy can be significantly saved, while the sorting efficiency is increased. This has the effect of achieving mass production of high quality selected grains.
