Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sorting machine for sorting immature rice from brown rice and broken rice from polished rice.

Conventional technology This kind of sorting machine, which has been used in the past, sorts immature rice or broken rice by placing brown rice or polished rice in a perforated cylinder, rotating the perforated cylinder, and shaking out the immature rice or broken rice from the holes. However, the unripe rice sorted by this type of sorting machine contains brown rice scum and small garbage, and the broken rice contains sugar, which deteriorates the quality of the immature rice and broken rice. I was letting it happen.

In addition, a horizontally long sorting tube with a circular cross section is constructed of a woven mesh in which vertical wire groups and horizontal wire groups form vertically long holes, and the iron tube is mounted obliquely inside the case. One end is the supply side, the other end is the discharge side, and a good rice removal gutter is attached to the discharge side.
A scrap rice receiving trough is provided at the bottom of the cylinder, and a waste rice take-out trough is formed at one end of the trough, and a straw waste trough made of a woven mesh with a coarser mesh than the above-mentioned one is installed inside the sorting cylinder in a concentric manner. The sorting tube is mounted on a shaft,
A grain sorting device equipped with a straw waste removal gutter on the discharge side of the wire section is known as Japanese Utility Model Application No. 51-102562, but this device uses double rotary perforated tubes for sorting.
It is necessary to install a screw conveyor to transport the scrap rice, which causes brown rice scum, small garbage, sugar, etc. to get mixed into the scrap rice, degrading the quality. It is something that cannot be done.

Furthermore, the cage body with the rotating sieve screen attached is fixed to the left and right support arms via bearings, and the cage support arms
The hopper base body is installed on the floor via an anti-vibration spring, and the oscillator mount is supported via a resonant rubber spring, and the rotating sieve and oscillator are driven by a single drive source. A vibrating rotary sieve that rotates the sieve and gives large vibrations in the vertical direction and small vibrations in the horizontal direction is known as Japanese Patent Publication No. 47-23502, but this is a rotating porous cylinder. The cage body is equipped with an oscillator that is a pie break, and the cage body is directly rotated and vibrated to improve the efficiency of the sieve, so multiple stages of sorting are not performed. Vibrations applied to the perforated tube can cause rice grains to clog the sorting holes, causing clogging, and have a negative impact on bearings and electrical systems.

Purpose of the invention The purpose of the invention is to eliminate the above-mentioned drawbacks, and to remove brown rice scum and grains from immature rice by using a perforated plate equipped with another pibrator without applying vibration to the rotating perforated cylinder. The purpose of the present invention is to provide a sorting machine that reliably sifts out sugar and other substances from broken rice, improves the quality of immature rice and broken rice, does not adversely affect bearings or electrical systems, and has a simple structure.

Structure of the invention The selection machine of the invention is a selection machine in which a perforated cylinder is rotatably provided in the main body, a perforated plate equipped with a pie break is provided at the bottom of the perforated cylinder, and the perforated plate is connected to the perforated plate through a cushioning material. The present invention has a configuration characterized in that the main body is provided with the following.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail based on the drawings. In FIG. A porous cylinder 2 with a large number of holes 3 smaller than the size of brown rice is rotatably attached, and a scraping blade 4 is attached to the end of the perforated cylinder 2.
A scraping blade body provided with several of these is made coaxial with the rotational axis of the porous cylinder 2, and configured to be rotatable together with the porous cylinder 2.

The separator main body 5 having the above structure is installed with the brown rice input port 1 side high and the scraping blade 4 portion low and inclined to some extent.

The sorting machine main body 5 is provided with an immature rice outlet 8 on the opposite side of the brown rice input port 1, and a funnel body 9 having a brown rice scum discharge port 10 is attached to the lower part of the porous cylinder 2 of the sorting machine main body 5. A perforated iron plate 7 is installed via the mounting plate 6.

11 is a pie break attached to the bottom of the funnel body 9.

In addition, when attaching the perforated plate 7 to the sorting machine main body 5,
A cushioning material 12 such as rubber or sponge is interposed between the perforated plate 7 and the mounting plate 6, and the pie break 11 is inserted by the cushioning material 12.
The vibrations are prevented from being transmitted to the porous cylinder 2.

Next, the operation of the embodiment of this invention will be explained.

Brown rice mixed with immature rice, brown rice scum, etc. is input from brown rice input port 1 and enters a rotating porous cylinder 2, and as the perforated cylinder 2 rotates, brown rice, immature rice, brown rice scum, etc. are sieved out. Then, small items such as immature rice and brown rice scum fall from the holes 3 of the porous cylinder 2, and the normal brown rice remaining in the porous cylinder 2 moves along the slope of the porous cylinder 2 into the raking blade body. Then, it is scraped up by the rotating scraping blade 4 and discharged from the discharge port.

Immature rice, brown rice scum, etc. that have fallen from the hole 3 of the perforated cylinder 2 are deposited on a perforated plate 7 placed at the bottom, and a funnel body 9 equipped with a pie break 11 is attached to the bottom of the perforated plate 1. Therefore, since the vibration of the pie break 11 is due to the attachment, the vibration of the pie break 11 vibrates the perforated plate I, vibrates the immature rice, brown rice scum, etc. accumulated on the perforated plate I, and The brown rice scum is sieved off through the holes of the perforated plate I, and the immature rice from which the brown rice scum has been removed moves along the slope of the perforated plate T, and is taken out from the immature rice discharge port 8.

Further, brown rice scum, small garbage, etc. that have fallen through the holes of the perforated plate 7 are collected in a funnel 9 and taken out from a brown rice scum discharge port 10.

Since a cushioning material 12 such as sponge or rubber is provided between the perforated plate 7 and the mounting plate 6, the vibration caused by the pie break 11 of the perforated plate is transmitted to the mounting plate 6 and the sorting machine main body 5. No effect.

Effects of the Invention As described above, the sorting machine of the present invention is a sorting machine in which a perforated cylinder is rotatably provided in the main body, and a perforated plate equipped with a pie break is provided at the bottom of the perforated cylinder. By providing a perforated plate on the main body through a cushioning material, by simply attaching a simple device to the sorting machine, the unripe rice that has been sorted from brown rice can be moved smoothly by the pie break, and the pie break causes slight vibrations. The perforated plate is definitely effective in removing fine powder such as brown rice scum from immature rice, and since the selected immature rice does not contain brown rice scum, etc., its utility value is wide and expensive. It is easy to configure.

Since the vibrations of the pie break are absorbed by the cushioning material, the vibrations are not transmitted to the perforated tube rotatably provided inside the main body, and therefore, there is no chance of rice grains getting stuck in the perforated tube and causing clogging. Furthermore, there is no adverse effect on bearings, electrical systems, etc.

Furthermore, in the case of sorting broken rice from polished rice, brown rice is replaced with polished rice, immature rice is replaced with broken rice, and brown rice is replaced with sugar.
