Description

[Detailed explanation of the idea] The present invention relates to an improvement of a grain size sorter.

In a grain size sorter with a plurality of porous-walled sorting tubes arranged in upper and lower positions, a plurality of fenestrations are provided in the front side wall of the sorter frame for entering and exiting each of the sorting tubes, and a lid body is provided on each fenestration. are provided so that they can be attached and removed freely, and a unique equalizing hopper is attached to the upper lid body, and a feed passage communicating with the sorting cylinder at the upper part is provided, and the lower lid body is connected to the sorting tube at the lower part. By providing a grain feeding path that communicates with the hopper and removably connecting it to the outlet of the hopper, the grain feeding device can be installed as low as possible, greatly improving its working efficiency, and making it easy to assemble and disassemble. The purpose is to develop and provide a device that is easy to carry, convenient for transportation, packaging, etc., has a simplified structure, and has a low manufacturing cost.

The present invention will be explained with reference to embodiment figures.

Reference numeral 1 denotes a cylindrical sorting machine frame, in which a plurality of porous wall sorting tubes 2 and 3 are arranged vertically and mounted inside the machine frame 1.
The sorting tubes 2 and 3 are connected to electric motors 4 and 5, respectively, for rotation, and the bottom of the machine frame 1 is provided with a first port 6, a second lower port, and a third port 8, which are ports for removing immature grains. This is a grain size sorter with a grain size sorting outlet 9 provided at one end.

On the front side wall 10 of the sorting machine frame 1, each of the sorting cylinders 2,
A plurality of fenestrations 11 and 12 are provided for entering and exiting the 3, and an upper lid 13 and a lower lid 14 are provided in each fenestration so that they can be attached and removed freely, and on the wall surface of the upper lid 13,
A proportioning hopper 17 equipped with a plurality of discharge ports 15 and 16 is attached to its lower part, and a grain feeding passage 18 is provided at one side of the discharge port 15 through the lid 13 and communicating with the sorting cylinder 2 in the upper part. At the same time, a grain feeding passage 19 is provided on the wall surface of the lower lid body 14 that passes through the lid body 14 and communicates with the sorting cylinder 3 at the lower part, so that the feed port 20 and the other side of the equalization hopper 17 are connected to each other. The discharge port 16 is removably connected to form a grain feeding device, 21 is a locking shaft of a porous wall sorting tube provided on the inner wall of the lid, 22 is a screw shaft to which the lid is attached, and 23 is a uniform This is a grain feeding cylinder for connecting the grain feeding pipe installed in the minute hopper.

When the above-mentioned bark is used, raw brown rice is supplied to the equalizing hopper 17 provided on the upper lid body 13 and the device is started, the brown rice in the equalizing hopper 17 is equally divided into the discharge ports 15 and 16 on both sides. The grains in the discharge port 15 on one side are passed through the grain feeding passage 18 of the upper lid body 13 to the upper porous wall sorting cylinder 2.
The grains from the outlet 15 on the other side flow into the lower lid body 14.
The grain flows into the porous-walled sorting tube 3 at the bottom through the feeding path 19, and is sieved into brown rice, immature rice, brown rice scum, etc. by the rotation of the sorting tubes 2 and 3, and the unripe rice flows through the porous wall of the sorting tube.・Small grains such as brown rice scum fall, and in the sorting process, as the brown rice moves, the falling immature grains tend to become larger, and are first sieved from the first opening 6 at the bottom of the sorter frame 1. The rice bran and small immature rice can be taken out, medium-sized immature grains can be taken out from the second lower opening, and larger immature rice can be taken out from the third opening 8.

The normal brown rice remaining in the sorting cylinders 2 and 3 is discharged from the grading outlet 9 along the inclined cylinder surface of the sorting cylinder.

As described above, the grain feeding device of the grain size sorter of the present invention is a grain size sorter equipped with a plurality of porous wall sorting tubes, and the equalizing hopper is installed in the upper lid, so the installation position can be adjusted as much as possible. The work efficiency of grain feeding is greatly improved, and the discharge port of the equalizing hopper provided in the upper lid body is removably connected to the supply port of the flow channel provided in the lower lid body. Each lid is attached or detached individually, making it easy to replace the porous wall sorting tube at the appropriate time, and its assembly and disassembly are simple and easy, which is convenient for transportation, packaging, etc., and its structure is simplified. This has the practical effect of reducing the manufacturing cost, smoothly performing the grain feeding equalization function of each porous wall sorting tube, and making it possible to reliably and quickly mass-produce selected grains of high quality.
