Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a sample grain extraction device for a grain oscillating sorter.

[Conventional technology]

The grain sorting action in this type of grain oscillating sorter is such that as the inclination/elevation angle of the sorting plate increases, the grains on the sorting plate are deviated to the rear, and the average oscillating angle, frequency, or amplitude increases. There is a characteristic that the flow is biased toward the front as the grain size increases, and the sorting action is affected by the difference in the properties of the grains, so if there is a change in the distribution of the grains, it must be immediately adjusted. These adjustments are usually made by changing the so-called sorting angle of the sorting board or increasing or decreasing the amount of grain fed to the sorting board. Adjustment of the guide wall that separates the boundaries between grain layers of paddy, paddy brown rice, and brown rice falling into the gutter.
It is necessary to collect and confirm samples near the guide wall.

By the way, in the conventional oscillating sorting machine, the guide wall was attached to the sorting board (1983-
17950, etc.), the guide wall swung together with the sorting board, making it dangerous and difficult to move and operate the guide wall, making it difficult to collect samples accurately.

In addition, it is desirable to surround the swinging sorting board with a cover for work safety and dust prevention reasons.
This makes it increasingly difficult to collect samples as the guide walls are adjusted.

Therefore, the applicant first vibrated a grain sorting machine with an uneven rough surface diagonally up and down, separated the mixed grains and guided them to the discharge end, and transferred the mixed grains to a vibrating conveying gutter provided at the discharge end. A receiving gutter for materials is provided on the lower wall of a guide wall that is movably and freely erected in the conveying gutter and is separated and discharged at separate locations. Utility Model Application No. 55-102987 proposed a sorted grain extraction device for a oscillating grain sorter equipped with an outlet, but this device did not allow the grains in the receiving trough to be discharged while the outlet was closed. Therefore, when the take-out port is opened, the grains that had stayed in the receiving trough are first discharged from the take-out port, and then the grains from the discharge end of the grain sorting board are discharged from the take-out port. A time lag occurs between the sorting state and the sample taken out.

In view of the above points, the present invention aims to provide a sample grain extraction device for a grain shaking sorter that can safely, easily and accurately collect samples, and can accurately detect the sorting status at any given time. Take it as a challenge.

[Means to solve the problem]

The sample particle extraction device of the oscillating sorter of the present invention includes a sorting plate with a rough surface arranged horizontally or gently inclined inside a fixed sorter cover frame so as to be able to swing freely in the forward and backward directions. Then, the mixed grains of paddy and brown rice fed onto the sorting board were separated in the front-back direction and flowed laterally, and brown rice, unhulled brown rice, and unhulled rice were placed in order from the front to the rear at the end of the board of the sorting board. In a sorting machine that discharges grains into three passages, an adjusting side wall movable in the front and back direction is installed on the inner wall surface of the sorting machine cover frame facing the end of the board, and different types of grains are disposed on the adjusting side wall. At the same time, a guide wall is installed perpendicularly to separate the guide walls, and a sample particle take-out gutter connected to the end of the panel is attached to one side wall of the guide wall, and a sample grain take-out gutter connected to the distal end of the panel is attached to the adjustment side wall. A sample grain opening is provided at a position facing the sample grain, an on-off valve for opening and closing the sample grain opening is provided, and a grain flow gap is formed between the on-off valve and the sample grain take-out gutter. It has a configuration characterized by:

[Effect]

Thereby, the adjustment of the guide wall is performed outside the sorter cover frame, and a part of the sorted grains flowing out from the sorter along the guide wall is transferred to the sample grain extraction trough outside the cover frame. It is done by collecting it.

[Embodiments of the invention]

A preferred embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 designates the entire rice hulling sorting device composed of a swinging sorter 2 and a hulling device 5 consisting of a hulling chamber 3 and a wind sorting chamber 4. Inside the sorting machine cover frame 6, a sorting frame body 9 in which a plurality of sorting plates 8 made of rough surfaces are superposed is mounted on the top of the swinging mechanism 7, and a sorting frame body 9 in which a plurality of sorting plates 8 made of rough surfaces are superposed is placed on one side of the upper part of the uppermost sorting plate 8. A grain feeding device 10 consisting of a vibrating conveyance gutter for equalization is disposed and integrally formed, and the hulling device 4 is located at the lower part of the hulling room 3 in which a pair of de-rolls 11, 11 are mounted opposite each other. A wind sorting room 4 consisting of a sorting air passage 12 and an exhaust fan 13 is provided, 14 is a paddy supply hopper, 15 is a paddy lifting machine, and 16 is a brown rice lifting machine.

Next, in the sample particle extraction device of the present invention, adjustment side walls 17 and 18 are installed on the inner wall surface of the sorter cover frame 6 facing the end face unend portion A of the sorting board 8, respectively, so as to be able to move laterally. At the same time, the adjustment side wall 1
Below 7, 18 are 3 aisles of paddy, paddy brown rice, and brown rice 1
A grain discharge gutter 22 with numbers 9, 20, and 21 is fixedly installed. Guide walls 23 and 24 for separating different types of grains are fixedly installed on each of the side walls 17 and 18 in a perpendicular manner, and a guide wall 23 provided on the side wall 17 for adjustment
A sample grain take-out gutter 25 communicating with the end A of the sorting board surface is installed on one side wall, and a sample grain opening 27 communicating with the outlet 26 of the take-out gutter 25 is provided on the side wall 17 for adjustment. A grain shovel 28 is provided outside the opening 27.
is provided and protrudes outward from the sorting machine cover frame 6,
The outlet 26 of the takeout gutter 25 and the adjustment side wall 1
A grain flow space B is provided between the sample grain opening 27 and the sample grain opening 27 of No. 7. An opening/closing valve 30 is provided on the inner wall surface of the adjustment side wall 17, and includes an adjustment lever 29 for opening and closing the sample particle opening 27, 31 is an operation rod for moving and adjusting the adjustment side wall 18, and 32 is an operation rod 29. 33 is an opening for moving the grain discarding tube 28 provided on the 6th side of the sorter cover frame, 34 is an elastic spring provided in the on-off valve 30, and 35 is an opening for displacing grains provided at the lower end of the guide wall 23. The plate 36 is a sliding frame provided on the adjustment side wall 17.

The adjusting operation rod 29 is formed so that it can be used both to move the guide wall 23 laterally and to open and close the opening 27 by rotating the on-off valve 30 back and forth.

With the above-mentioned configuration, raw material paddy is transferred to the paddy supply hopper 1.
4 and when the device is started, the paddy flows down between the de-rolls 11 and 11 in the hulling chamber 3 and is removed, and the dehulled grains are wind-sorted in the sorting air passage 12 in the wind-selection chamber 4. The light rice husks are removed from the machine via the exhaust fan 13. The mixed grains of paddy and brown rice are collected at the bottom of the sorting air passage 12, and are fried to the grain feeding device 10 of the oscillating sorter 2 by a mixed grain lifting machine (not shown). The mixed grains of paddy and brown rice in the grain feeding device 10 are conveyed by the swinging motion of the swinging mechanism 7 and are evenly supplied to the surfaces of each sorting board 8. In each sorting board 8 (see Fig. 2), the swinging action concentrates the brown rice flow rate P on the higher side of the sorting board 8 and the paddy flux R on the lower side, and also concentrates the rice flux R on the lower side of the sorting board 8. Then, the paddy/brown rice mixed grain flux Q is flowed and discharged from the horizontal plate terminal part A to the grain discharge gutter 22, and the brown rice flux flows down to the brown rice passage 19 and is carried by the brown rice grain lifting machine 16. The flux of mixed grains of paddy and brown rice taken out of the machine is mixed grain passage 2.
0 to the wind sorting chamber 4, and is returned to the sorting board 8 through the mixed grain lifting machine to be re-sorted. It is returned to the supply hopper 14 and released again. If the flow distribution state of grains on the sorting board 8 changes due to an increase or decrease in the amount of raw material paddy supplied or changes in conditions such as the above-mentioned inclination/elevation angle and vibration frequency, the brown rice flux P of the sorting board 8 changes. The adjusting operation rod 29 of the guide wall 23 provided at the discharge side boundary with the mixed particle flux Q is moved horizontally on the guide wall 23 and stopped while inspecting the surface of the sorting board 8, and the operation rod 29 is rotated. When the opening/closing valve 30 is opened, a part of the sorted grains flowing down from the sorting board 8 into the sample grain take-out gutter 25 along the guide wall 23 flows in from the opened sample grain opening 27.
The state of the paddy collected by flowing down the grain dumping tube 28 and mixed into the sample grains is detected, and this collection and detection work is repeated while moving the guide wall 23 as appropriate, so that the paddy is mixed into the brown rice flux P. In this state, the work of moving the guide wall 23 and the work of collecting sample grains were completed,
The selection action is read with the on-off valve 30 in the closed state.

Further, when the on-off valve 30 is closed, the sample grains in the take-out gutter 22 flow down from the grain flow room B to the lower brown rice passage 19 and are discharged outside the machine.
On the other hand, the guide wall 24 provided at the discharge side boundary between the mixed grain flux Q and the paddy flux R is normally moved and adjusted by inspecting the grain flow distribution state. A sample may be collected by providing a take-out gutter similar to the take-out gutter 25.

〔Effect of the invention〕

In this way, the sample grain extraction device of the oscillating sorter of the present invention detects the modulation of the flow distribution state of the grains on the sorting plate by sampling a part of the sorted grains flowing out from the sorting plate along the guide wall. The guide wall provided with the grain extraction gutter is moved and adjusted, and the on-off valve of the sample grain opening connected to the extraction gutter is opened and closed to collect the grains, thereby preventing the collection of the sorted grains for the sample and the contamination of foreign species. can be detected safely and reliably.

In addition, when the opening for sample grains is closed by the on-off valve, the sample grains that have flowed into the sample grain take-out gutter are immediately discharged from the grain flow passage into the passage and remain inside the sample grain take-out gutter. Therefore, when the sample grain opening is opened, the sample just discharged from the sorting plate can be immediately taken out, and the sorting state at that time can be accurately detected.
