Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic grain switching and guiding device in a hulling plant.

In other words, in a hulling plant, when the mixed rice after hulling is separated by a oscillating sorter using grain sorting plates, especially at the beginning of operation, it is difficult to determine whether or not a large amount of paddy is mixed in the brown rice that has been sorted. While accurately detecting the brown rice using a color sensor, it is possible to automatically switch between circulating and re-sorting the brown rice and sending it to the brown rice extraction station, instead of manually detecting it as in the past. The purpose of this invention is to provide a method that can be carried out conveniently and automatically without any problems.

Next, we will discuss the embodiment shown in the drawings.

Figure 1 shows a part of the rice hulling plant.
As shown in , the brown rice receiving trough (6) in the shaking sorter (A) is connected so that it can be supplied from the upper part of the receiving mixed rice elevator (4) to the supply tank (5) of the shaking sorter (A). A color sensor (S) capable of detecting the condition of paddy is installed in the vertical conveyance path (B) which is connected to the four general conveyance paths below the position of the color sensor (S). In the lower part of (B), a branch path (2) is formed that branches into the ring source port (7) and the outlet port (8), and a switching valve (3) that can be freely switched across the branch path (2) is formed. ) is connected to the operating rod α0 of the solenoid (9), and the solenoid (9) and the color sensor (S)
and connect through one control box and color-i
The switching valve 1) (3) is installed so that the switching operation can be performed by the detection signal of the 5 noser (S).

In addition, the front nF2 Monkey New Year's Day (7) and the lower part of the mixed rice elevator (4) are connected as shown by the arrow (B), and the delivery port (8) and the good brown rice elevator (12+) are connected to each other as shown by the arrow (B). VC connection is connected as shown in c), and it is installed so that 18 rice machines and a total of 4 h4 machines and 41 rice machines can be sent to the river as shown by the good brown rice elevator (arrow from the top of 1).

Configure.

As shown in Figures 2 to 5, the rocking i% type A) is made by stacking a plurality of grain selection plates (11) having a rough surface on the upper surface and moving them in the horizontal (X) and vertical (Y) directions. ) is supported from each lower swinging rod 113) K, and the swinging device (
The supply tank ( 5) A tank 1 is installed to receive grain from the grain board (1) and feed it onto each grain selection board (1), and the lower part 11 of each grain selection board (]) in the subordinate direction (Y) is installed.
At the bottom of the outer side of one end are a brown rice catcher (6) and a mixed rice catcher (
16) and the paddy receiving gutter (17) with a partition plate (1Σl
1181 are interposed and installed in parallel, and the brown rice receiving channel (6) is 1 general feed channel (Bj vc ren,') as described above, and the j month 11C is installed 7, lI' + - combined rice receiving tiHj 061 is viSki mixed rice rise l 亦(・hiki(4n, -yota j sword・n(,11self+
7+ 1J It is configured by connecting each of them to the hulling machine side.

However, at 17, during work 11, when the paddy rice remover v = 2 rice or mixed rice elevator (4) is sent to the supply tank (4 people moving through 51k), Each 12? - Separation by role plate (1) by 1 unit 'C brown rice (d brown rice receiving trough (ii) VC1 mixed rice 1d mixed rice receiving trough (161, paddy is received paddy f + 71 VC each dropped) In particular, at the beginning of operation, 4 inches of paddy was mixed into the vcIr-1 brown rice, and the rice was in a bad condition.
When brown rice passes through the conveyance path (B), the color sensor (S) detects it and activates the solenoid (S) to send out the bJJ valve (3) as shown in Figure 1. (8)
We had to switch to light, so we harvested a large amount of paddy.
, Brown rice l-J: The mixed rice is sent from the ring entrance (7) to the mixed rice elevator (4) (11) and then sorted by the folding sorter (A).

In this way, when the paddy in the brown rice passing through the conveyance path (El) runs out, the solenoid (9) is activated by the detection by the color sensor (B), and the cut-off valve (3) is turned on as indicated by the arrow. As shown in the figure, the first day (71ill) is turned down and switched, and then the Ryogenmai elevator jl'At is
The rice is sent to QL for rice selection, moat, and removal ceremony.

In this way, the present invention installs a color sensor that can detect the mixed state of paddy on the side where the brown rice is taken out after the mixed rice after hulling is sorted [F] by the oscillating sorter using the grain sorting board. Conveyance paths are provided in succession, and at the rear of the conveyance path, a branch path is provided that communicates with the swinging sorter fil and the brown rice removal side, and a switching valve operated by the color sensor is installed in the branch path. Because it was installed freely, especially at the beginning of operation, when there is a large amount of rice mixed in with the brown rice sorted by the shaking @ sorter, the color sensor can accurately detect and remove it by switching the switching valve. In addition to being able to circulate the brown rice in different ways, a color sensor detects when there are fewer paddy in the brown rice and switches the switching valve to send it to the brown rice extraction side. It has the advantage that it can be carried out accurately by the color sensor and can automatically guide the switching without having to do so.
