Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a grain sorting machine, and was developed for sorting out damaged grains of general grains, especially summer grains of OJ% type and true density.

In general, legumes have a near-spherical shape, are unstable on a flat plate, and are extremely susceptible to transfer. They usually differ in shape or elasticity.

The present invention is a sorting machine that utilizes the differences in shape and elasticity between intact grains and damaged grains, as well as the difference in their specific gravity, to combine a structure and function suitable for sorting.

The present invention will be explained with reference to embodiment figures. In Figure 1,
Reference numeral (1) is a porous wall sorting plate formed on a wavy surface by a large number of mountain-shaped veins (2), and the sorting IF (1) vibrates back and forth with its front stop, and nine supply gutter ( 8) From the sorting board (1), mix the mixed grains supplied with K.

While separating into the front and rear, each flows laterally and is provided in the wood section of the sorting plate ('1).

The separated grains are discharged to a complete grain discharge port (4), a mixed grain discharge port (5), and a damaged grain discharge port (6).

Figure 2 is a side sectional view of a large number sorter equipped with a plurality of sorting plates (1), in which the inside of the closed machine frame (7) is formed into multi-stage side chambers (8) and (9). Then, install the porous wall sorting plate (1) in each side chamber (8) (9), respectively, and
) is supported by support rods (15) (16) at the upper support point (10) (it) and the lower support point (1B) (14) of the support frame (12) in order to vibrate after pongee. The crank (1) attached to the force application point (17) and the support frame (12)
8) are connected by a rod (19). Also, the concubine (
8) or (9), horizontally suspended porous wall sorting board (1
) is formed into an air exhaust chamber (2o), and an air exhaust port (22) is provided on the swinging side machine frame side III (21) in front of it, and the lower part of the sorting plate (1) is formed into an air exhaust chamber (28). ) K
At the same time, the swinging side machine frame side wall ffJ)K
A ventilation opening (25) is provided, and a wind pipe (29) with a flexible part (28) made of an elastic membrane is installed in a separate ventilation device (name) and ventilation device (27). The ventilation opening (25) of the ventilation chamber (28) is connected to the ventilation chamber (9).
2o) are respectively connected to the exhaust ports (22). 1st
In the figure, the air blower (26) and the air exhaust device (27) have an overlapping cylinder part (81) consisting of an inner cylinder and an outer cylinder.
According to 2) or (88), the ventilation opening (shape) of the ventilation chamber (28) is connected to the ventilation opening (22) of the ventilation chamber (20). Note that the cross section of the overlapping cylinder portion may be formed into an arbitrary shape such as a square or a circle, and a gap may be provided between the overlapping portions.

With the above-mentioned configuration, when the raw material beans are fed into the supply gutter (8) K and the device is started, the closed machine frame (7) internal porous wall sorting IN (1) vibrates back and forth until it stops. In addition, in the case of a porous wall, from the ventilation chamber (28) on the lower side to the ventilation chamber (28) on the upper side.
0), so the sorting plate (1) surface Kt
The falling legumes flow down the sloping wavy surface in a transverse manner, forming a flat grain layer, and are divided into incomplete grains (half-split) with low specific gravity by the blowing action from the porous wall surface. grains, damaged grains) float to the top of the grain layer, and complete grains with high specific gravity gather at the bottom of the grain layer, and due to the vibration of the chevron veins, the complete grains at the bottom of the grain layer float forward to a high position. The incomplete grains that floated to the upper surface of the grain layer drift horizontally while being pushed up to the side, forming a complete grain flux (P). The flow is deflected to form a damaged grain flux (6), and between each flux (P) (6), a mixed grain flux of intact grains and damaged grains is formed, and the xylem travel of the sorting plate is The sorted particles of each flux (Takumi (2) and (B) flow down to the complete grain outlet (4), mixed grain outlet (6), and damaged grain outlet (6) and exit the machine. be discharged.

According to claim (2), the inside of the closed machine frame is made into a multi-stage field! ! (8) (9) Since the screening plates are mounted on each wound guide, the screening action of multiple screening plates can be smoothly performed using a single vibrator and blower.
! Can be done 1. In addition to simplifying the structure, the selection ability is increased and high-quality selected grains can be quantified, which has an island effect.

The book of Patent Claims 0IllI Sections @) and (4) provides that the blowing device or the blowing device is a wind pipe having a flexible part made of an elastic membrane or a wind pipe having a polymeric tube part. Since they are connected to the air outlet of the front delivery air chamber or the air outlet of the air exhaust chamber, the connecting portions are vibration-proofed and the safety of the air blower and the air exhaust device can be ensured.

Thus, in the grain sorting machine of the present invention, a porous wall sorting plate with a wrinkled surface formed by a large number of chevron-shaped veins is suspended horizontally in a closed machine frame and is vibrated, while the machine frame is blown with air. Since it is connected to a device and blows air from the porous wall of the machine, the difference in shape and elasticity between perfect grains and damaged grains, as well as the difference in their specific gravity, causes the perfect grains to be pushed upwards on the higher side of the sorting plate and deflected laterally. A complete grain flux is formed by flowing the damaged grains, and the damaged grains are flowed to the lower side of the sorting plate while passing in the lateral direction K.
IHII to form a damaged grain flux, and a mixed grain flux of complete grains and damaged grains is formed between each of the above fluxes, and each is discharged to the xylem path of the sorting plate, so that the vibrating wave surface and jet force are This allows for smooth, high-precision sorting and reliable mass production of selected grains, and the use of a sealed machine frame with a simple and highly efficient structure reduces manufacturing costs and reduces the amount of dust. It has remarkable effects, such as completely preventing the scattering of water to the outside of the machine and maintaining a good working environment at all times.
