Description

[Detailed Description of the Invention] The present invention applies, for example, to processing brown rice, etc. after hulling.
The present invention relates to a face angle control device that keeps the non-Ω slag +'i tI: included in the sorting process after separation approximately constant in a hand sorting machine that is used for every minute.

In general, when it comes to brown rice, the product value decreases due to the large amount of immature grains being mixed in, while the amount of uncut I grains being mixed in increases.
By decreasing l, grain selection efficiency decreases and brown rice (
There was a problem that reduced the amount of grains taken out (products), but in the past, grain sorting after grain sorting was done monthly by the operator's eyes, so it was difficult to always obtain a constant shearing standard. There was a problem that the proportion of immature grains contained in the grains was uneven.

The present invention addresses the problem described in item L, and is equipped with a grain sorting cylinder that is continuously rotated to separate sorted grains and immature grains. 6. In the supported device, a grain selection angle adjusting member for changing the grain selection angle of the grain selection cylinder, and a grain selection angle adjusting member for controlling the operation thereof. ! While a sensor is installed, immature grains leaking from the vicinity of the inclined end of the grain sorting tube are taken out as a detection sample for the sensor, and the 74th grain I'r from the grain sorting tube is taken out as a detection sample for the sensor. The sensor that detects the leakage star change can efficiently remove ripe grains, easily improve the efficiency of the grain sorting operation to take out sorted grains compared to the conventional method, and also improve the slope of the two ends where a large amount of immature grains leak. By detecting the amount of immature grains at the lower end of the slope of the grain sorting tube, which has a smaller leakage amount than the senosa, it is possible to appropriately detect changes in the amount of immature grains.
You can easily set this detection standard value etc. in F.
In particular, at the end of the sorting process, the undetected immature grains by the sensor due to the grain selection angle change in H4 are larger than the tilted end of the grain sorting tube, so the grain selection angle control operation should be taken promptly to achieve an extremely It is an object of the present invention to provide a grain sorting angle control operation of a grain sorter that allows accurate grain sorting angle.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In addition, a grain sorting chute (15) receives the grains from the opening at the inclined lower end of the grain sorting tube (8), and an immature grain chute (16) receives the immature grains leaking from the sorting hole (7). In addition to installing it in the machine frame (5), the grading chute (15) is placed in the hopper (18) of the grain frying conveyor (17), and the immature grain shoe 1-(16) is placed in the receiving container (18). Let me come.

Furthermore, a sample chute (20) is provided to receive immature grains leaking from the sorting hole (7) at the lower end of the grain sorting tube (8), and a sample gutter (22) is equipped with an immature grain sensor (21).

The immature particle sensor (21) is formed by a potentiometer (27) connected through the intermediate operation shaft (26), and the sensing arm (25) can be made approximately horizontal by adjusting the way 1- (24). The immature grains from the sample shoe 1- (20) are brought into contact with the backing plate (23), and the plate (23) is lowered for 1 hour in proportion to the amount of immature grains, and this displacement j- is controlled by the potentiometer ( 27) to detect the amount of immature grains from the sample chute (20).

FIG. 2 is a grain selection angle (A) control circuit diagram of the second grain selection cylinder (8), in which a grain selection angle adjustment circuit (29) equipped with a reference value setting device (28) is provided to The adjustment circuit (29) is connected to the potentiometer (27) of the sensor (21) via the amplifier (3o), and when the number of immature grains decreases, the adjustment circuit (29) is connected to the potentiometer (27) of the sensor (21). When the grain angle reduction circuit (32) increases, the grain selection motor (12) is connected to the adjustment circuit (29) to control the motor (12) in dry and reverse direction, and the grain selection cylinder (8) Grain selection angle (
A) is changed so that the size of immature grains from the sample chute (20) is maintained at approximately the same level, and the ratio of immature grains during grading from the grading chute (15) is kept approximately constant. .

The present embodiment is constructed as described above, and the grain sorting tube (8) is supported at an angle with the end opening on the grain size removal side facing downward, and the grain sorting tube (8) is moved in one direction by the sorting motor (9). The interior of the grain sorting tube (8) is continuously rotated to supply unsorted grains such as unhulled brown rice into the grain sorting tube (8) from the supply hopper (+1) and chute (10) into the grain sorting tube (8). There is a sorting hole (7) on the way from the upper end of the slope to the lower end of the slope.
While the immature grains (including waste grains) leak through the filter, the grading tube (8) also flows through the slanted lower end side opening of the grain sorting tube (8), and the immature grains are sorted and unaged. Separate yourselves and fly
