Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a detection device for detecting paddy and brown rice in a huller, and is used for husking control, etc.

[Problem that the invention seeks to solve]

The polished rice that is husked in the husking section is fed to a rotary sorting cylinder where it is separated into paddy and brown rice, and the remaining paddy in this rotary sieving tube is returned and supplied to the husking section again to be husked. In addition, the mixed rice, which is a mixture of unsorted paddy and brown rice, is not fed back into the rotary sorting cylinder, so in a huller that performs hulling and sorting, it is possible to remove the removed rice, returned paddy, returned mixed rice, etc. In order to have different reduction routes,
Q: It is difficult to detect the accurate mixing state of paddy and brown rice in the mixed rice to be supplied to the first transfer sorting section.
[Means for Solving the Problem] This invention is provided in a rotary sorting cylinder (1) that separates mixed rice into paddy and brown rice while rotating, and removes the crushed rice scraped out in the scraping part (2). A sensor (3) for detecting the mixing of the paddy and brown rice is installed at the supply port (3) which mixes the rice and the remaining mixed rice that has been sorted in the sorting tube (1) and supplies it to the sorting tube (1).
4) A paddy and brown rice detection device for a hulling machine is configured as follows.

[Operation and effect of the invention]

The brown rice and unhulled rice that has been removed by the threshing section (2) is fed from the supply port (3) into the rotating rotary sorting cylinder (1), where it is sorted to separate most of the brown rice and paddy. The 1 kongo rice that has been separated from a small amount of paddy and has not been completely sorted is returned to the sorting tube (1), but at this time, it joins and mixes with the washed rice that is successively transferred. The rice passes through the supply port (3), and at this time, the sensor (4) detects the mixed state of brown rice and paddy, and the sorting tube (1)
), the mixed rice at this supply port (3) is in a sufficiently mixed state with the removed rice and the returned mixed rice immediately before being fed into the rotary sorting cylinder (1). Therefore, it is possible to maintain accurate detection of the mixed state of brown rice and paddy.

:Example] In addition, in the illustrated example, after [ ) 11, a pair of de-pudding rolls (
5) A paddy hopper (6) is provided on the 1- side of the phusher (2), which supplies paddy to the phusher (2). and a reduction hopper (7) that again supplies the reduced paddy sorted in the sorting section to this shredding section (2), and a sorting hopper (7) is installed in the front part below this shredding section (2). It has a wind suction fan part (8) and a sorting air passage (9) that communicates with this fan part (8), and a sorting air passage (9) located at the rear lower end of this air passage (9) to separate the rolled rice on one side. Transfer helical part α that transfers in the direction
A wind selection room OD is provided with an interior of the wind selection room OD, and at the rear of the wind selection room α℃, there is an air flow path 0z that communicates with the air flow path (9) and wind-selects brown rice, and this air flow path O3. Brown rice sorting room 03 equipped with a transfer helix located at the lower rear end to transfer the brown rice in one direction.
is provided integrally with the wind-selecting chamber (+3), and on the upper side of this brown rice-selection chamber (+3) there is a recess (141) into which brown rice can be fitted over almost the entire inner circumferential surface. A sorting chamber α9 equipped with a rotary sorting cylinder (1) is provided.

A pair of left and right rollers αeQ61 are provided at both ends of the rotary sorting cylinder (1), respectively, for rotating the sorting cylinder (1), and these front and rear rollers α1lQQ61f: a pair of roller shafts 07 are mounted on the rotary sorting cylinder (1). ) α force is rotatably supported on both i force removal walls (18+09) of the sorting chamber α~, and in the center of the sorting cylinder (1), the rear walls α & 0 of the IJ
A pair of left and right transfer helices 1υ are installed adjacent to each other, and each of the pair of transfer helices (1) C11 is provided with a pair of helices (1) C11 below which surrounds the left and right rivers 11 and the bottom of these helices (1) C11. The gutter (2) + 23 is supported by the front and rear walls (18) (1'J), and the adjacent upper ends of both gutter tubes have tips attached to the inner circumferential surface of the sorting tube (1). The brown rice partition plates (2) are provided so as to be rotatably adjustable, and the sorting tubes (3) are also installed at the upper end of each of the two plates I22 (C) on the negative side.
1) A mixed rice receiving plate (to) and a brown rice receiving plate (a) which are inclined with their tips close to the inner circumferential surface of A fall path (a) will be provided for the transported brown rice.

Also, at the front end of the left helical gutter ■, there is a helical gutter □□
A supply tank (■) for supplying the washed rice is installed at □, and at the rear end of this helical gutter (A), the mixed rice transferred by the transfer helix (1) is dropped into the sorting tube (1). A supply port (3) is provided to protrude downward, and this supply port (3) is provided to protrude downward.
On the protruding left and right sides of 3), a senna (4) consisting of a light emitter and a light receiver is provided to detect the mixing of paddy and brown rice.

In addition, (branch) is the transfer helix (IQ:) The thrower 1 field is used to transfer the crushed rice transferred by the IQ to the supply tank (to) 1J. The thrower 1Gη which is transferred back to the hopper (7) is a thrower which discharges brown rice that has fallen from the drop passageway out of the machine.

The paddy in the one-side hopper (6) is passed through a pair of dehulling rolls (5)
(5), the rice husks etc. are removed by flowing down the sorting air passage (9), and the grain is transferred in one step by the transfer helical part 00, and fried in the supply tank (c) by the thrower. Ru. The 1P1 rice of brown rice and paddy in this supply tank (c) is transferred to the rear in the helical gutter (a) by the helix ■ and is supplied from the supply port (3) to the rear part of the rotary sorting tube (1). , forming a sedimentary layer and being transported forward,
It is scooped up in the rotation direction by the rotation of the sorting cylinder (1),
The brown rice in the bottom layer that fits into the small recess α of the sorting tube (1) is
A helical gutter (a) is installed between the brown rice partition plate (2) and the brown rice receiving plate.
The rice is transported forward by the helix 121) and falls from the drop passageway, crushed rice and the like are removed by the air passage O2, and then discharged to the outside of the machine by the thrower 01). Also, sorting tube (1)
