Description

[Detailed description of the invention] The present invention relates to a vertical grain sorting machine.

In conventional vertical grain sorting machines, although it is possible to sieve out waste grains from long grains, it is not possible to separate the waste rice into multiple types according to size.

In other words, even if a standard is set for a certain size and rice is separated into two types: rice that does not meet that standard and rice that does meet that standard, the rice that does not meet that standard is still considered to be as close to good rice as possible. , very poor quality small rice is mixed therein, and the present invention is designed to solve this problem by returning the scrap rice that is close to good quality to the good rice, or to take it out as scrap rice. This can be done simply by switching the switching valve.

The present invention provides a vertical cylinder with a spiral blade attached to the outer periphery of a vertical rotating shaft, and surrounds the outer periphery of the spiral blade concentrically with a perforated cylinder,
In a structure configured such that grain is supplied from the lower end and discharged from the upper end, and the grains are selected through the perforated cylinder during the process, a long grain discharge port is opened at the top of the perforated cylinder, and a long grain discharge port is opened outside of the long grain discharge port. A long grain storage tank is attached to the holder, a medium grain discharge chamber is formed at the upper part of the outer periphery of the perforated cylinder, a small grain discharge chamber is formed at the lower part of the medium grain discharge chamber on the outer periphery of the perforated cylinder, The gist of this machine is a vertical grain sorting machine with switching valves installed between the grain discharge chamber and the storage tank, and between the medium grain discharge chamber and the small grain discharge chamber.

To explain with a diagram, 1 is the vertical rotation axis, and the vertical rotation axis l
A drum-shaped vertical cylinder 2 is attached to the holder, and a spiral blade 3 is attached to the outer peripheral surface of the vertical rotation axis l. The outer periphery of the spiral blade 3 is a perforated tube 4
surround concentrically. The perforated tube 4 is connected to the vertical rotation axis l.
Its lower end is supported by rollers 5 so as to rotate around it. The lower end of the vertical cylinder 2 is surrounded by a fixed cylinder 6, and a hopper 7 is attached to the fixed cylinder 6. 8 is a straw waste removal board, and 9 is an earth and sand removal board.

A long grain discharge port 10 is opened at the upper end of the porous cylinder 4, and a scraping blade 11 is provided outside the long grain discharge port 10. 12 is a storage tank, and the long grains discharged from the long grain outlet lO are stored in the storage tank 12.

The porous cylinder 4 is double surrounded by an outer cylinder 13 except for a part of one part, and a small particle discharge chamber 1 is provided inside the outer cylinder 13.
form 4.

A medium particle discharge chamber 15 is formed above the small particle discharge chamber 14 on the outside of the porous cylinder 4, and a switching valve 16 is attached to the medium particle discharge chamber 15, and a flow path 17 leading to the tank 12 and the small particle discharge chamber 14 are connected to each other. A flow path 18 is formed. 19 is a scraping blade, 2o and 21 are discharge ports, 22 is a motor, and 23 is a transmission section.

Since the present invention has the above-described configuration, when the motor 22 is energized, the vertical cylinder 2 rotates clockwise and the porous cylinder 4 rotates counterclockwise. In this state, when grains are put into the hopper 7, large pieces of straw are removed when the grains pass through the straw removal plate 8, small pieces of earth and sand are removed when they flow down on the earth and sand removal plate 9, and the grains are transferred to the fixed tube 6. It flows into the lower end of the inside. The grains that have flowed into the fixed cylinder 6 rise due to the action of the spiral N3 due to the rotation of the vertical cylinder 2.
The long grains are discharged from the long grain discharge port 10, stored in the storage tank 12, and taken out from the discharge port 20, but since the perforated tube 4 is rotating in the opposite direction during this time, the small grains are taken out into the small grain discharge chamber 14. The medium-sized grains are taken out to the medium-grain discharge chamber 15 and scraped out by scraping blades 19, respectively. At this time, if the switching valve 16 is switched to the position indicated by the solid line, the medium grains will be transferred to the storage tank 1.
When the switching valve 16 is switched to the position shown by the dotted line, the medium-grain grains flow into the small-grain discharge chamber 14 and are taken out together with the small rice from the discharge port 21. be.

Among the above configurations, the present invention is characterized in that a switching valve 16 is provided in the medium particle discharge chamber 15 to form a flow path 17 leading to the storage tank 12 and a flow path 18 leading to the small particle discharge chamber 14. , and can be selected according to the rice crop.

That is, in the conventional vertical grain sorting machine, when sieving out waste grains from long grains, it was not possible to adjust the amount of waste rice to be removed.

In other words, even if a standard is set for a certain size and rice is separated into two types: rice that does not meet that standard and rice that does meet that standard, the rice that does not meet that standard is still considered to be as close to good rice as possible. In such cases, scrap rice that is close to good quality may be mixed with good quality rice to some extent.

The present invention provides a vertical cylinder 2 with a spiral blade 3 attached to the outer periphery of a vertical rotation axis l, and surrounds the outer periphery of the spiral blade 3 concentrically with a perforated cylinder 4, and supplies grain from the lower end and discharges the grain from the upper end. death,
In the structure in which the grains are sorted using the perforated cylinder 4 during that time, a long grain discharge port 10 is opened at the top of the perforated cylinder 4, and a long grain storage tank 12 is provided outside the long grain discharge port IO. A medium grain discharge chamber 15 is formed at the upper part of the outer periphery of the porous cylinder 4, and a small grain discharge chamber 14 is formed at the lower part of the medium grain discharge chamber 15 at the outer periphery of the porous cylinder 4. Room 1
5 and the storage tank 12 and between the medium-grain discharge chamber 15 and the small-grain discharge chamber 14, the vertical grain sorter is provided with a switching valve 16, so that the grain is spirally shaped by the rotation of the vertical cylinder 2. It rises to - due to the action of the blades 3, is discharged from the long grain discharge port 10, is stored in the storage tank 12, and is taken out from the discharge port 20, and the small grains are stored in the small grain discharge chamber 14, and the medium grains are The medium grains are taken out to the discharge chamber 15, but if the switching valve 16 is switched to the position shown by the solid line at this time, the medium grains will be mixed into the storage tank 12.
When the switching valve 16 is switched to the position shown by the temporary line, medium-sized grains flow into the small-grain discharge chamber 14, and thus the separation state of waste rice can be adjusted.
