Description

[Detailed description of the invention] The present invention relates to improvements in grain sorting equipment.

In general, legumes have a spherical shape and are unstable when resting on a flat plate, making them extremely prone to rolling. However, damaged grains that have been damaged by insects, diseases, fertility problems, and mechanical damage have a different shape or shape than whole grains. They typically have different elasticities.

11 The present invention provides surface-shaped ridges with a unique structure on a porous wall sorting plate with a corrugated surface, and also provides long grooves for directional blowing air in the ridges, thereby separating intact particles, damaged particles, and large debris. The purpose of this project is to develop and provide a device that can efficiently sort materials by utilizing the differences in shape, specific gravity, elasticity, etc. between materials.

The present invention will be explained with reference to embodiment figures. In Fig. 2, the symbol (1) is a porous wall sorting plate formed on a wavy surface by a large number of chevron-shaped veins (2). Sorting plate (1) from supply port (3)
While separating the mixed grains fed to the front and rear sides, the mixed grains flow laterally to the complete grain discharge port (4) and the mixed grain discharge port (
5) The damaged grain discharge ports (6) are formed to discharge the sorted grains respectively.

FIG. 1 shows a grain sorting machine equipped with the porous wall sorting plate,
A porous wall sorting plate (1) with a supply port (3) on the - side is mounted at a gentle slope, and an exhaust chamber (7) is mounted on the upper part of the sorting plate (1).

(16) (15) Supported by (16), the force application point of the machine frame (9) and the crank (18) of the vibration device (17)
are connected by a rond (19), and a blower device (20) is provided at the bottom of the air blowing chamber (8) to communicate with an air supply port (21) provided at the bottom of the chamber (8), and (22) is a supply Mouth (3)
an elevator for hoisting the raw materials, and the sorting plate (1).
) has multiple directional long grooves for blowing air (23...
) are installed laterally in parallel to the wavy surface, and light imperfect particles, etc. flowing on the ridges (24) are jetted toward the lower side (A) of the plate surface and flow down. It is shaped like this.

(25) is a side wind tunnel provided in the upper lid (26) of the ventilation chamber (7), and the wind tunnel (25) is provided at a lateral position on the lower side (A) of the sorting plate (1). (27) is an air exhaust port connected to an air exhaust device (not shown).

With the above-described configuration, when the sample peas are put into the supply port of the elevator (22) and the device is started, the sample peas flow down from the supply port (3) onto the porous wall sorting plate (1) at the bottom and are supplied. . The porous wall sorting plate (1) vibrates the wavy surface of the sorting plate back and forth until the oil is removed by the vibrating device (17). (8) through 12 toward the exhaust chamber (7), so that the beans supplied to the porous wall sorting plate (1) are
IHT is applied to a slanted wavy surface.

Therefore, a flat grain layer is formed, and due to the blast action from the porous wall surface, incomplete grains (damaged grains and half-split grains) with low specific gravity float to the top of the grain layer. , complete grains with a large specific gravity gather at the bottom of the grain layer, and due to the vibrating action of the mountain veins, the complete grains at the bottom of the grain bed are pushed up forward and toward the higher side, drifting laterally from each other and forming complete grains. The incomplete grains that form a flux (P) (see Figure 8) float on the grain layer - F plane, and slide laterally on the upper surface of the complete grains, drifting laterally to the damaged grains. A flux (R) is formed, and each flux (P) (
A mixed grain flux (Q) of whole grains and damaged grains is formed during R), and each flows to the floor path of the sorting plate and is separated and discharged, but in general, pulses are Because a large amount of lightweight incomplete particles and bulky debris are mixed in,
In the present invention, a planar ridge (24) in which directional long grooves (28) for blowing air are arranged in a row is installed horizontally in parallel to the wavy surface on the upper surface of the sorting plate (1). Therefore, the incomplete grains floating on the upper surface of the grain layer of the sorting plate (1) slide down the grain layer surface in a tilted manner and flow onto the ridges (24), and also flow onto the ridges (24).
4) The wind ejected from the long groove (23) for blowing air on the surface causes the jet to flow diagonally upward on the lower side and contact the upper lid body (26), and when falling, the incomplete particles etc. are at a lower position. The bulky debris flows or slides toward the side wind tunnel (25).
25), the damaged grains fall separately and accumulate in the damaged grain flux (R) formed on the lower side of the sorting plate, and the damaged grains are collected at the damaged grain outlet (R) provided at the end of the sorting plate. At the same time, bulky debris is removed from the machine from the air outlet (27) of the side wind tunnel (25).

As described above, the blowing device of the grain sorter of the present invention has a planar projection in which long grooves for directional blowing air are arranged in a row in the sorting process of the porous wall sorting plate formed on the wavy surface. As a result, non-perfect grains, etc. (damaged grains and bulky debris) flowing down on the ridge are jetted toward the lower side of the sorting plate surface, so that the separation and sorting action between perfect grains, damaged grains, and bulky debris is accurate and accurate. This method can be carried out quickly, greatly improving the sorting performance, and has the effect of ensuring mass production of high-quality selected beans at all times.
