Description

[Detailed description of the invention] The present invention relates to an improvement in a feeding device for a grain sorter.

In general, grains such as pigeon oats and beans have an inverted spherical shape and are unstable on a flat plate, making them extremely susceptible to rolling. Generally, the shape or elasticity of grains differs from that of whole grains.

This type of grain sorter feeds the grains to a perforated wall sorting plate with a corrugated surface, and utilizes the differences in shape, elasticity, and specific gravity between whole grains and damaged grains to classify whole grains, mixed grains, and damaged grains. It is a device that separates the grains into different fluxes, sorts them, and discharges them to the xylem process, and the grains are contaminated with large amounts of foreign matter such as bulky waste and dehulled husks due to their harvesting and unhulling conditions. This had the disadvantage of disturbing the grain flow on the sorting plate and reducing sorting accuracy.

The present invention solves the above-mentioned drawbacks by installing a vibrating feed gutter with a unique structure in the raw material supply section on the swinging side of the sorting plate, thereby completely eliminating the foreign matter in the feeding process of the sorting plate. In addition, it is an object of the present invention to develop and provide a device that supplies only grains smoothly and quantitatively, performs a highly accurate sorting action, and reliably mass-produces selected grains of high quality.

The present invention will be explained with reference to embodiment figures. Fig. 1 shows a grain sorting machine, in which a corrugated perforated wall sorting plate (1) with a supply port (2) on the negative side is mounted in a gently inclined manner. A blower chamber (3) is provided at the bottom to integrally form a sorting machine frame (4), and a swing mechanism (5) and a wind turbine box (6) are arranged in relation to each other at the bottom of the machine frame (4). The porous wall sorting plate (1) is swung by the swinging mechanism (5), and the wind generated in the wind turbine box (6) is formed to blow upward from the lower surface of the sorting plate (1). , (7) is an elevator, (8) is a grain tank suspended from the elevator, (9) is an operating handle of the angle adjustment device, and (10) is an electric motor.

Fig. 2 is a partially cutaway plan view of the sorting machine frame (4), and shows a grain discharge gutter (11) in the wood section of the porous wall sorting plate (1).
In addition to installing the guide wall (12) (12) in the gutter.
erected to separate eight outflow channels, and at the bottom of the gutter there are a complete grain outlet (18), a mixed grain outlet (14), and a mixed grain outlet (14).
Each of them is provided with a damaged grain outlet (15). The raw material supply section on the swinging side of the sorting plate (1) has a supply port section (16) on one side of the gutter body, and a contaminant discharge port section (on the other side).
A vibrating supply gutter (18) provided with a vibrating feed gutter (17) is mounted horizontally or in a gently inclined manner and fixed to the sorter frame (4), and a porous wall surface (20 ), and a grain threshing port (21) is provided below the porous wall surface (20).
A downstream receiving trough (22) is provided in a horizontal structure and is integrally formed, and (2B) is a mounting plate that connects the supply trough to the sorting machine frame.

With the above-mentioned configuration, when the raw material beans are fed into the food elevator (7) and the device is started, the beans are fried by the elevator (7) into the upper grain tank (8), and the grains are lifted into the tank. The beans (8) are fed to the supply opening (1) of the vibrating supply gutter (18).
6) and flows down into the gutter body. and the supply gutter (18)
vibrates together with the sorter frame (4), so the beans in the gutter form a flat grain layer in the gutter due to the vibration action and flow toward the discharge side, during which time the beans flow through the porous wall surface ( 20
) from the through hole to the lower flow receiving trough (22) surface, and flows down the ψ surface and is supplied to the grain separating plate (1) from the grain discharging port (21) at the end of the machine. In addition, bulky debris remaining in the gutter
Contaminants such as removed husks are oscillated and conveyed in the gutter and are discharged from the contaminant discharge port (17) at the end of the machine. Next, the beans supplied to the sorting plate (1) form a flat grain layer on the wavy plate surface due to the vibration of the sorting plate, and
Due to the blowing action from the ventilation holes in the porous wall, incomplete grains with low specific gravity float to the top surface of the grain layer, while complete grains with high specific gravity gather at the bottom surface of the grain layer, and the mountain shape of the wavy plate surface Due to the pulsating vibration action, the complete grains at the bottom of the grain bed are pushed upwards forward and drift laterally, increasing the complete grain flux (
The incomplete grains that formed P) and floated to the top of the grain layer are
The upper surface of the complete grain is deflected in the lateral direction while being on the rear lower side KfffiL to form an incomplete grain flux (6), and each of the above fluxes (P)
(6) A mixed flux of complete grains and incomplete grains (forming Q,
The grains of each flux are removed from the grain discharge gutter (
The grains are discharged to the outside of the machine from the complete grain discharge port (18), the mixed grain discharge port (14), and the damaged grain discharge port (15) through the respective outlet paths in 11).

Next, in paragraph (2) of the first patent claim, the downstream receiving gutter f22A) connects the gutter bottom (19) to the porous wall surface (24).
Therefore, the wind blowing out from the porous wall of the sorting plate (1) in the sorting machine frame (4) is directed to the vibration supply gutter through the receiving gutter (22A) in the direction of the dotted arrow (4) in Fig. 4. (18A) The porous wall surface (20) is jetted upward from the bottom surface (a lid is provided on the top of the sorting plate to guide the wind) to remove the impurities staying on the porous wall surface (20) through the exhaust tube ( 25) has the effect of streamlining the discharge action and improving the efficiency of sorting out impurities.

In addition, claim (8) provides a vibration supply gutter (18B) (D porous wall surface (2OA)), a chevron (
a) 4 are arranged in a row to form a wavy surface (28), so the peas are swayed by the ridges (27) of the wavy surface (28), and the amount of conveyance becomes constant; This has the effect of increasing the blast area of the sorting plate and improving sorting efficiency.

(9) In claim (4), since the foreign matter outlet portion is formed in the foreign matter collection chamber (29) at the mouth, the scattering of foreign matter is prevented and the working environment is improved. It has the effect of keeping it clean.

In this way, the feeding device of the grain sorter of the present invention feeds the raw material grains in one process by using the vibrating feed gutter with a unique structure installed in the raw material supply section on the swinging side of the porous wall sorting plate. It is possible to completely remove foreign substances such as bulky waste and grain husks that are mixed in with the grains, and to quantitatively and smoothly supply grain particles to the sorting plate, thereby continuing normal and efficient sorting action. It can be carried out in a number of ways, and has the effect of ensuring mass production of all selected grains of high quality through highly accurate sorting.
