Description

[Detailed description of the invention] The present invention relates to an oscillating sorter.

Conventionally, this type of oscillating sorting machine has a multi-stage sorting board that oscillates using a oscillating device, and a partition plate that separates brown rice and mixed rice is placed at the JJ+ outlet along the JJI Dehi. A sensor is provided so as to be movable and fixable in the direction of the sorting 5Ia, and detect grains in a direction along the direction C'discharge] on the near side of the discharge] with respect to the flow direction of the grains on the sorting 5Ia. A device is installed, and when the sensing device is activated, the root barrier (A) is automatically moved and tightened within a predetermined range via a drive device to adjust the position of the partition between brown rice and mixed rice. . By reciprocating the diagonal vertical movement of the sorting board, brown rice with heavy specific gravity is distributed towards the upper shaking side, paddy with lighter specific gravity is distributed towards the lower shaking side, and the unseparated mixed rice is separated between them. The distribution of paddy in the grain flow direction on the cutter varies depending on the sorting condition. If the paddy distribution curve is set to pattern A in the case of I feel terrible.

In the A3 of this type of conventional oscillating sorter, for example, the amount of movement of the partition plate is fixed to one pattern of the paddy distribution curve, which is the grain sorting distribution boundary, by the sensing device. Because I had set the settings in advance, when I followed the set pattern and the sorting was good, the partition moved and the brown rice came out mixed with υ1 l of brown rice. As a result, the sorting efficiency decreases, and the partition plate does not move enough on the lifting platform with poor sorting, resulting in brown rice (unpaddy being mixed in and being discharged at the JL exit). In some cases, there was a problem that the sorting efficiency was reduced.

This invention was devised in view of the above problems, and its purpose is to provide an oscillating sorter to improve sorting efficiency.

In order to achieve the above object, the present invention provides a sorting board 1"-
A plurality of sensing devices 3 are arranged at predetermined intervals in the direction along the discharge port 2 of the sorting ff11 to sense the sorting distribution boundary of the grains.
Corresponding to the movement of the 1 boundary (of the grains moving at the exit 2), a partition plate 4 is provided that partitions the 11 boundary (1) of the grains that move at the 1 exit 2. The apparatus is a separate swinging type machine, which is equipped with a device 5 that changes the amount of movement of the partition plate 4 in accordance with the change in the pattern of the boundary line of the sorting distribution of the grains. It's something that has happened.

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

Next, the operation of the above embodiment will be described.

Grain in the grain tank 7 enters the receiving tank 6 from the output port 1-8 and is supplied to the inclined upper part of the sorting board 1 from the supply port. As the paddy flows down the sorting board 1 that reciprocates diagonally up and down, it is sorted based on the difference in specific gravity. Mixed rice (each amount is taken out from mixed rice outlet 10).

Then, the reference voltage of the reference voltage setting circuit 1'-J corresponding to the analog switch M5 and the voltage of the potentiometer 15 set depending on the position of the partition plate 4 are connected to the differential amplifier P.

Ru.

In this way, the position is adjusted by moving the partition plate according to the sorting condition of the grain, and the switching device 5 is adjusted according to the pattern of the paddy curve 5, which changes depending on the sorting condition of the grain. By switching, the amount of movement of the partition plate 4 is changed as shown in FIG. There is no chance that rice will get mixed in at the exit 9 of No. 1 or that the efficiency of rice grains will be lowered due to the moving droplets.

As is clear from the above, according to the configuration of the present invention, one of the plurality of sensing devices senses the sorting distribution boundary of the grains on the sorting board, and this sensing causes the sorting distribution boundary of the grains to move at the JJI exit. The partition plate moves in response to the movement of the granules, and the U1 outlet can be partitioned near the granule sorting distribution boundary (q. Therefore, it is necessary to avoid moving the partition plate in advance of the movement of the sorting distribution boundary at the discharge port. This makes it easy to perform the sorting properly.Moreover, the sorting unit uses a platform and a sensing device to sense that the pattern of the IJ boundary of the sorted grain changes depending on the shape of the grain. The upper part I + boundary discharge 1" Since the relative positional relationship with which distribution boundary shifts, 1
If the moving part of the partition plate is set according to the movement of the IJ field, the movement of the partition plate may move too much with respect to the sorting distribution boundary of the discharge port, or the movement of the partition plate may be too much. However, the switching device changes the pattern at the boundary of the sorting distribution (correspondingly, the movement m of the partition plate is changed (there was a pattern change at J). Move the partition plate properly and close the sorting embankment.
1 exit can be properly partitioned. For this reason, it is extremely unlikely that a sorting failure or a decrease in sorting efficiency will occur.

This invention is not limited to the embodiments described above (indeed, the invention may be implemented in modes other than the embodiments described above).
