Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of a grain size sorter for grains, sediment, and other grains, and is particularly concerned with the improvement of grain size sorters for grains, soil, and other grains, and in particular for dissimilar grains that have the same grain size but differ only in length. It was developed to streamline the sorting action, prevent clogging of the sorting holes, and perform the sorting function smoothly.

In general, particles with the same width and different lengths, such as elongated or oblong particles such as rice grains and wheat flour, are generally l/2
It is impossible to sort human crushed particles using a normal sorting method that penetrates the width of a hole.

This is because the width and thickness of crushed grains are equal to the width and thickness of whole grains. In order to sort out these types of particles, it is natural to form an impenetrable hole with a bottom in the wall of the sorting cylinder, and a mixture of particles of different lengths and short lengths is flowed into this cylinder and fitted into the hole near the bottom of the cylinder. As the sorting tube rotates and the particles that fit in rise, the angle of the pothole becomes tilted, and the long particles fall out of the pothole earlier than the short particles, fall into the mixed grains near the bottom of the tube, and are mixed with only short particles. The particles rise while remaining in the pot hole, and when the pot tilts to a certain angle, they finally fall out of the pot hole, so in that phase, all of the short particles that have infiltrated the pot hole drop out of the pot hole in the cylinder wall. However, the long particles fall into an upwardly open hopper located below and are discharged outside the machine, and long particles are normally discharged from an outlet near the end of the sorting cylinder and are sorted into individual particles.

However, in this sorting method, some of the short particles may fit inside the pot hole and become permanently stuck in the pot hole due to the frictional force.In other words, the sorting tube rotates and the particles fall out. Even if it reaches the phase where it is, the hole in the pot is clogged with particles, making it impossible to escape from the hole, and eventually it becomes useless as a sorting machine. In other words,
It can be said that pot-hole type sorting machines will remain unfinished forever unless this fatal flaw, clogging, can be completely prevented. In the present invention, since the bottom of the pot hole of the sorting tube is made of an elastic material, the elastic material attached to the outer circumferential surface of the sorting tube is sorted by a roll mounted on the axis at an appropriate position from the outer circumference, that is, a phase that allows short particles to fall from the pot hole. By pressing inward into the cylinder, the bottom of the pothole pushes out even short particles that have been fitted into the pothole, so clogging never occurs.

In short, the present invention solves clogging of the pot holes, which has been considered a fatal common flaw in pot-hole sorting methods that sort particles by length, and for which no countermeasures have been taken. By changing the depth of the pot hole to be shallower, the particles that have entered the pot can be removed from the pot hole and fall out, completely solving the problem and preventing clogging of the pot hole.This is the first time that a pot hole type sorting system that sorts particles by particle length can be used. The successful completion of the machine was a notable effect.

7 To explain the present invention using an example diagram, a porous wall sorting tube 2 having a covering wall 1 made of an elastic material such as plastic attached to the outer circumferential surface is supported on wheels 3, 4, 5, and 6 in a diagonal shaft shape and rotated. death,
A circumferential ring 7 fitted near both ends of the sorting tube 2 and wheels 3, 4,
5 and 6 are exterior.

The roll 8 that presses the outer peripheral surface of the elastic material covering wall 1 has its driven wheel 9 in circumscribed contact with the circumferential trunk ring 7 and is rotated by the drive of the sorting cylinder 2, and the sorting cylinder 2 is driven by a pulley 10 provided on its outer periphery and It is rotated with a belt 11 suspended between it and the pulley. Inside the sorting cylinder 2, there is provided a socket 13 for a hopper 12, which is supported so as to be rotatably adjustable at a position approximately below the axis of the roll 8, and whose upper part is open in an approximately V-shape. The bottom of the pipe 112 is formed in an inclined shape, and the outlet 17 is formed on the outflow side wall.
has been opened. As shown in FIG. 3, when the elastic material covering wall 1 of the sorting tube 2 rotates and reaches the area surrounding the roll 8, the covering wall 1 closes and forms the bottom of the through hole 14 of the porous wall sorting tube 2. By pressing the bottom P of the pot hole 15 and protruding into the pot hole 15, the depth of the pot hole 15 is changed to be shallower, and the particles 16 that have been fitted are pushed out from the pot hole 15 and fall out, so that the particles 16 are forced out of the pot hole 15. Even the short particles that were stuck inside can easily escape, so the pot hole 15 is constantly cleaned, and the risk of clogging is completely eliminated, and we have succeeded in completing a particle length sorter that does not cause clogging at all.
The effect of being able to realize for the first time, in name and reality, the most difficult task of sorting particles by length is remarkable.

The short particles 16 that have fallen out of the pot hole 15 fall into the hopper 12 and are taken out of the machine from the outlet 17 provided on the outflow side wall of the hopper 12, while the long particles are placed on one side of the sorting tube 2. The particles are discharged to the outside of the machine from the provided discharge port 18, and long and short particles are sorted out.

Reference numeral 19 denotes a hopper for supplying raw materials into the sorting cylinder 2.

Note that the shape of the porous wall pot hole of the sorting tube of the present invention is arbitrary and not particularly limited. Further, the roll may be made of any material such as elastic material or metal.
