Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a vertical grain size sorter used for sorting small rice mixed in brown rice after removal.

(Prior art) Conventionally, this type of vertical particle size sorter was developed in 1983.
-There is a method described in Publication No. 12276, but in this technology, the supply port of the material to be sorted is located above,
The feeding operation is extremely difficult, and since the outer periphery of the feeding hopper connected to the upper part of the conveying helix is supported by rollers, its driving and support are unstable. The gap between the cylinder and the conveying helix is not constant. Further, in this prior art, no consideration is given to the assembly structure of the sorting cylinder and the conveying helix.

(Problems to be Solved by the Invention) This invention attempts to solve the above-mentioned drawbacks of the prior art, improve the sorting performance, and facilitate the attachment and detachment of the sorting tube and the like.

(Means for solving the problem) The inside of the vertically long outer shell 12 is divided into a lower drive chamber 14 and an upper sorting chamber 15 by a base 13,
A grain receiving cylinder 43 communicating with the supply chute 39 is mounted on the base 13, and a sorting cylinder 1 which opens a peripheral sorting hole and an upper discharge port 29 is erected in communication with the grain receiving cylinder 43. A gear box 20 for changing the speed of the electric motor 16 mounted on the drive chamber 14 side is attached to the lower surface of the base 13, and a drive engaging portion 22 is protruded from the gear box 20 to the upper surface of the base 13. The lower ends of the large-diameter fried grains 4 housed inside the grain receiving tube 43 and the sorting tube 1 are removably fitted into the joint 22, and the canopy 27, which can be detached and attached to the upper part of the outer shell 12, The vertical grain sorting machine has a configuration in which a shaft 6 fitted into the top plate 9 of the grain 4 and the top plate 41 of the sorting tube 1 is held.

(Operations and effects of the invention) The brown rice supplied from the chute 39 to the grain receiving tube 43 is sequentially fried by the grain fryer 4, and the small rice is removed from the sorting hole of the sorting tube 1, which is installed in communication with the grain receiving tube. The leaked and sorted particles are discharged from the discharge port 2 at the top of the sorting cylinder 1.
Released from 9. During this sorting action, the lower part of the fried grain body 4 and the sorting cylinder 1 is a rigid base 13.
The top plate is supported stably by the top plate, and the top plate is fitted and supported by the shaft 6 held by the canopy 27, so that the long grain grains 4 and the sorting cylinder 1 can be held securely. In addition, the gap between the fried grains 4 and the sorting tube 1 is kept constant, allowing for accurate sorting.

Also, when removing the sorting tube 1 and the grain frying tube 4 for maintenance inspection, etc., by removing the canopy 27 from the outer shell 12, the canopy 27 between the frying tube 4 and the sorting tube 1 can be removed.
The holding state of the grain body 4 is released, and the grain body 4 can be pulled upward and disengaged from the driving engagement portion 22 on the base 13 to be easily taken out. Can be withdrawn.

(Example) In the illustrated example, 11 is a machine base, and 12 is a cylindrical or square cylindrical outer shell mounted on the machine base 11, the lower part of which is supported by a base 13 located at the lower part. A drive chamber 14 in which the transmission device 7 is housed is partitioned at the upper part into a post-surgery sorting chamber 15.

16 is a drive motor, 17 is a transmission belt, 18 is an input pulley, and 19 is an input shaft, which transmits power into a gearbox 20 attached to the lower surface of the base 13, and a rotating disk 21 that projects above the base 13 from the gearbox 20. It is configured to drive.

A fried grain body 4 is placed on the rotary disk 21 and is driven and rotated by being engaged with driving engagement portions 22 and 22 that protrude upward from the rotary disk 21. The grain frying body 4 is composed of a large-diameter cylindrical body 2 having a hollow interior and a continuous spiral 3 formed on the outer periphery of the cylindrical body 2.

The drive shaft 6 is drivably supported at its lower part by a transmission device 7, and extends upward through the grain frying body 4.

The cylindrical sorting tube 1 stands in communication with a grain receiving tube 43 attached to the upper surface of the base 13 and is positioned so as to house the fried grain 4 therein.
The drive shaft 6 is configured to be driven and rotated by engagement between a metal 42 attached to the drive shaft 6 and a prismatic engaging portion 5 provided at the upper end of the drive shaft 6.

Further, 23 is a bearing holding frame provided on the upper top plate 9 of the fried grain body 4, 24 is a bearing to be held, and 8
is a metal formed by expanding downwardly the fitting hole 10 into which the drive shaft 6 is fitted, and is fitted and locked with the prismatic locking portion 25 of the drive shaft 6. 26 is a snap ring.

Reference numeral 27 is a canopy of the outer shell 12, and 28 is a support metal, which rotatably supports the upper end of the drive shaft 6.

29 is a large particle discharge port opening at the upper part of the cylindrical sorting tube 1; 30 is an upper partition plate provided in an annular shape facing inward from the outer shell 11; 36 is a large particle scraping blade provided in the sorting tube 1; The grains are scraped out to a discharge port 32 opened on one side of the outer shell 12. 33
is a hopper, and 34 is a valve.

Reference numeral 35 denotes a lower partition plate, which protrudes inward from the outer shell 12 in an annular shape, and is connected to the cylindrical sorting tube 1.
This is to catch small particles leaking from the pipe. 36 is a small particle scraping blade which is detachably attached. 37
is the small particle outlet.

Furthermore, 38 is a guide roller that guides and supports the lower outer periphery of the cylindrical sorting tube 1, 39 is a supply chute, and 4
0 is a grain receiving plate provided at the lower end of the fried grain body 4.

Next, the operation of the vertical particle size sorter of the present invention will be explained. In the grain sorting operation, when the material to be sorted is supplied from the supply port 39 into the grain receiving cylinder 43, the grains are fried while being applied with centrifugal force by the rotation of the grain frying body 4.
The small particles leak out from the mesh of the cylindrical sorting tube 1 and fall onto the lower partition plate 35. The fallen and accumulated grains are discharged from the small grain discharge port 37 by the small grain scraping blade 36. In this way, the sorting work progresses gradually along with the grain lifting action, and only the large grains reach the upper end of the cylindrical sorting tube 1, are discharged from the large grain outlet 29 onto the upper partition plate 30, and are further subjected to the rotating action of the large grain scraping blades 31. It is then supplied to the hopper 33.

Maintenance and inspection work for the cylindrical sorting tube 1 and the grain frying body 4 is performed by first removing the canopy 27 of the outer shell body 12, and
The cylindrical sorting tube 1 from which the small particle scraping blade 36 has been removed is pulled upward. Subsequently, the fried grain body 4 is pulled upward. Next, the cylindrical sorting tube 1 and the grain lifting body 4 are maintained and inspected, and when this is completed, the grain lifting body 4 is inserted into the outer shell 12 while passing the drive shaft 6 inside, and the rotating disk 21 The drive engagement portion 22 is engaged with and placed on the drive engagement portion 22 . During this assembly, it is extremely difficult to insert the tip of the drive shaft 6 into the spiral metal 8 because the grain lifting body 4 has a sealed structure to prevent grains from leaking inside. Since the fitting hole 10 into which the drive shaft 6 is fitted is expanded downward, when the tip of the drive shaft 6 is aligned with the large diameter part of the metal 8, the taper shape allows the fitting hole to fit smoothly. Can be combined.

Subsequently, the cylindrical sorting tube 1 is inserted into the outer shell 12 from above to accommodate the fried grain 4, and the engaging portion 5 at the tip of the drive shaft 6 is fitted into the metal 42.
Finally, the small particle scraping blade 36 is attached to the sorting tube 1, and the canopy is assembled.
