Description

[Detailed description of the invention] (Industrial application field) This invention is based on the sorting holes in the sorting tube that are installed around the grains while frying grains such as unhusked brown rice using a spiral body for frying. The present invention relates to a vertical grain sorting machine for sorting small rice from grains.

(Prior art) In this type of vertical grain sorting machine, the applicant of the present invention has already developed a technique for returning the rice leaking from the sorting hole into the sorting cylinder to change and adjust the sorting rate. It has been filed as Utility Application No. 1988-88431.

(Problem to be solved by the invention) In the invention of the prior application mentioned above, the grains sorted by the sorting tube are returned to the supply area at the bottom of the sorting tube to change the sorting rate, and for this purpose, the structure is extremely simple, but in this embodiment, the sorted millet is returned to the supply path that supplies the sorted grains to the supply area at the bottom of the sorting cylinder, so the flow of the reduced rice is Accurate changes in the sorting rate may not be possible due to interference from the sorted grains supplied.

This invention attempts to solve the above-mentioned problems.

(Means for Solving the Problem) A spiral body 3 for fried grains is installed rotatably in a sorting tube 2 having a large number of sorting holes 1 on its circumferential surface, and the grains are supplied to a grain supply area 4 in the lower part between the two. In the vertical grain sorting machine, which is configured to sort the grains while frying and sort the millet by leakage, an appropriate amount of sorted millet leaking from the sorting hole 1 is returned to the grain supply area 4 for sorting. In order to be able to change the rate, a control valve 7 that is independent of the supply route 5 that supplies grains to the grain supply area 4 and that is in communication with the sorted millet discharge route 6 is provided that can adjust the amount of return.
This is the configuration of a sorting rate changing device for a vertical grain sorter, which is provided with a small rice return passageway 8 having a grain sorting machine.

(Operation of the device) The millet that leaks out from the sorting hole 1 of the sorting tube 2 and is sorted is passed through the millet return passage 8 which is independent of the grain supply passage 5.
The grains are returned to the grain supply area 4, fried again by the grain frying spiral body 3, and re-sorted by the sorting tube 2, but this grain contains a lot of millet, and some millet is not sorted. It is discharged together with the grains without leaking through hole 1, and the sorting rate is changed.

In addition, when changing the amount of return, operate the control valve 7 in the communication section between the millage discharge path 6 and the millage return passage 8 to change the amount returned to the grain supply area 4 and the amount to the outside of the machine. This is done by changing the ratio of emissions.

(Effects of the invention) Since this invention is constructed as described above, the millet that leaks and is sorted from the sorting hole 1 of the sorting tube 2 is returned to the grain supply area 4 at the bottom of the sorting tube 2 to increase the sorting rate. In terms of modification, since the millet return passage 8 is provided independently of the supply route 5 for supplying grains to the grain supply area 4, the supply route 5 is not connected to the flowing grains as in the past. Therefore, the supply of reduced rice is not hindered, and the reduced rice can be smoothly returned to the grain supply area 4 and the sorting rate can be adjusted accurately.

(Example) In the illustrated example, 9 is a casing that encloses the entire casing, and inside the casing 9 is a cylindrical sorting tube 2 with a plurality of sorting holes 1 bored in the circumferential surface, and inside the sorting tube 2. A spiral body 3 for fried grains to be housed in is erected concentrically.

The space inside the casing 9 is filled with a drive unit installation plate 10.
A lower partition plate 11 and an upper partition plate 12 divide the chamber into a drive chamber 13, a supply area 40, a sorting area 14, and a take-out area 15 from below.

Reference numeral 16 is a prime mover, and a gear box 1 is fixed to the drive unit installation plate 10 via a belt transmission device 17.
8, and is further configured to drive and rotate the spiral body 3 for fried grains by an output shaft 19 from the gear box 18.

Reference numeral 20 denotes a drive shaft, which extends upward from the gear box 18 through the output shaft 19, further passes through the fried grain spiral body 3, and is supported by the bearing 21 of the casing 9. The square shaft portion 22 of 20 and the square bearing 23 of the sorting tube 2 are fitted together to rotate the sorting tube 2 at a low speed in the opposite direction to the spiral body 3. Reference numeral 24 denotes an idler wheel that guides and regulates the lower outer periphery of the sorting tube 2.

Further, 25 is a fixed cylinder installed on the drive part installation plate 10, and a grain supply area 4 is formed between the fixed cylinder 25 and the spiral body 3, and a hopper is provided in the grain supply area 4. The terminal end of the grain supply path 5 that communicates with 26 is connected.

A part of the lower partition plate 11 is constituted by a bran removing net 27, and a chute 28 is provided below the bran removing net 27 for discharging the selected bran to the outside of the machine. Further, an outlet 29 for sorting small rice is opened on the lower side of the rice bran removing net 27 in the rotational direction of the sorting tube 2.
At the bottom of the outlet 29, a discharge chute 30 forming a sorted rice discharge path 6 extends outside the casing 9.

In addition, a millet return passage 8 whose terminal end communicates with the grain supply area 4 is communicated in the middle of the millet discharge path 6, and the ratio between the return amount and the discharge amount to the outside of the machine can be changed in this communication section. A regulating valve 7 is provided, which can be configured to be configurable. 31 is its adjustment lever.

Reference numerals 32 and 32 are scraping blades, which are fixed to the outer periphery of the sorting tube 2 and are used to separate the upper partition plate 12 and the lower partition plate 11.
The grains are transferred by sliding and rotating on the top.

A grain discharge port 33 is opened at the top of the sorting tube 2 and communicates with a storage hopper 34 fixed to the casing 9.

The grains supplied from the hopper 26 to the grain supply area 4 via the supply path 5 are fried by the spiral body 3, and the millet is leaked through the sorting hole 1 of the surrounding sorting tube 2 and left behind. The sized particles fall from the discharge port 33 onto the upper partition plate 12, are transferred by the scraping blades 32, and are taken out to the storage hopper 34.

In addition, the small rice leaking from the sorting hole 1 is removed from the lower partition plate 1.
1, the rice is transported by scraping blades 32, transferred over a bran removing and sorting net 27, and after the bran is removed and removed, it is passed from the outlet 29 to the outside of the machine via the discharge path 6 formed by the discharge chute 30. taken out.

Depending on the type of brown rice, if too much rice is leaking through the sorting hole 1 and is being sorted, the rice discharge route 6
The control valve 7 with the small rice returning passage 8 communicating with the small rice returning passage 8 is adjusted by the adjusting lever 31, and an appropriate amount of discharged small rice is supplied to the small rice returning passage 8. The millet that has been diverted to the millet return passage 8 flows down the independently provided millet return passage 8 and is supplied to the grain supply area 4, where it is again fried and re-sorted by the spiral body 3. This grain contains a large amount of millet, and some of the millet does not leak through the sorting hole 1 and is further fried and taken out from the discharge port 33 along with grading.
The grain sorting rate is changed.
