Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting plate inclination angle adjusting device in a hulling adjustment device comprising, for example, a hulling device, a lifting III device, and a swinging sorting device.

Conventionally, this type of oscillating sorting device detects the distribution of paddy and brown rice on a sorting plate and adjusts the inclination angle of the sorting plate every time the distribution changes. However, such adjustment requires frequent adjustment of the angle of the sorting plate, resulting in frequent changes in the distribution of paddy and brown rice, making it impossible to obtain stable sorting performance.

In addition, conventionally, a partition plate installed to separate the sorted paddy, mixed rice (a mixture of paddy and brown rice), and brown rice from the sorting grain outlet of the sorting plate is used to separate the sorted paddy, mixed rice, and brown rice. There was one that adjusted its movement according to the state of distribution. However, in this case, for example, if the partition plate between brown rice and mixed rice is moved to the brown rice side because the distribution area of mixed rice has expanded, the amount of mixed rice to be discharged increases.

Therefore, when continuous operation is performed in which the discharged mixed rice is circulated and supplied again to the sorting plate, the circulating mixed rice and the scraped rice supplied from the hulling device are combined and supplied to the sorting plate. As the amount of mixed rice gradually increases, the distribution area of the mixed rice on the sorting board also expands accordingly. Therefore, the partition plate had to be moved further toward the brown rice side, and as a result, the partition plate was too close to the brown rice side, making continuous operation impossible.

The present invention was devised in view of the above-mentioned problems, and provides a sorting plate inclination angle adjustment device in a hulling adjustment device that can be automatically controlled to enable continuous operation with constant sorting performance. It is something to do.

To achieve this objective, the present invention provides an angle adjustment device 1.
A swinging sorting device 5 is provided which can adjust the swinging angle of the sorting plate 3, and the sorting plate 3 has a sorting lees discharge lower which corresponds to the boundary between sorting and refining of different kinds in order to discharge different kinds of sorted grains separately. partition plate 11 which partitions the sorted waste discharge lower and is movable along the sorted waste discharge lower by driving the movement adjustment device 9 in response to a command that detects the movement of the border of sorting and refining.
A detection device 13 is provided which detects that the partition plate 11 has been adjusted to move within a predetermined range and issues a signal, and upon receiving the output signal of this detection device 13, the movement adjustment of the partition plate 11 is adjusted to the predetermined range. A control device 15 is provided to control the angle rx adjustment device @1 so that the angle rx adjustment device @1 can be operated within the vehicle.

Hereinafter, one embodiment of the present invention will be described in detail based on the accompanying drawings.

On the other hand, the sorting plate 3 is provided with a detection device 13 that detects that the brown rice partition plate 11a has been adjusted to move within a predetermined range and generates a signal. This detection device 13 includes an upper limit switch 13a that detects when the brown rice partition plate 11a is adjusted to move within a predetermined range toward the shaking side 3a, and a lower limit switch 13a that detects when the brown rice partition plate 11a is adjusted to move within a predetermined range toward the shaking side 3b.

In addition, in the figure, 59 is a hulling device consisting of a paddy funnel 61 and a removal rod 63, 65 is a rice receiving gutter, 67 is an I grain cylinder, 69 is a supply tank, and 71 is a This is a receiving tank.

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

The drive device 17 is activated to drive each part. The sorting plate 3 is oscillated via a oscillating device 21.

Paddy is supplied to the paddy funnel 61. The supplied paddy is rubbed by the dehulling roll 63 and falls downward. The fallen rice is F
The RM rice is supplied to the sorting plate 3 via a receiving gutter 65, an m* cylinder 67, a supply tank 69, and a receiving tank 91. The scraped rice supplied to the sorting plate 3 is oscillatedly sorted by the shaking of the sorting plate 3, the paddy is returned to the paddy funnel 61 from the paddy discharge port via a predetermined conveyance route, and the mixed rice is The mixed rice is also returned to the frying cylinder 67 from the mixed rice discharge port and is again supplied to the sorting plate 3.
The brown rice is similarly conveyed from the brown rice discharge port to the brown rice discharge device, and is taken out and processed. In such a situation,
Depending on the preset angle of the sorting plate 3, paddy, mixed rice, and brown rice are properly sorted on the sorting plate 3, and continuous operation is performed.

Now, due to changes in the hull removal rate in the hulling @ 59, if the amount of paddy increases in the grained rice fed onto the sorting plate 3, the boundary A between the refined and brown rice areas in Figure 3 will be brown rice. Move to the area. In this case, sorted grains are taken out from the sample take-out port 33, and these grains pass through a photosensor (S) grain by grain in a flow path (not shown), and the photosensor (S) determines whether the grains are paddy or brown rice. emit different signals depending on the This signal is input to the paddy/brown rice discrimination circuit 37 of the movement control device 35, as shown in FIG. The paddy/brown rice discrimination circuit 37 receives and outputs a signal generated by the photosensor S when detecting paddy. This signal is input to the paddy count pulse output circuit 39. The paddy number pulse output circuit 39 outputs a number of pulse signals corresponding to the number of input signals. This pulse signal is input to the counter circuit 41. The counter circuit 41 counts the number of output pulses from the paddy number pulse output circuit 39,
The timer 47 counts a number greater than or equal to the specified number in a predetermined time set by the timer 47 and outputs an upper level signal P+ (not shown).
Output. This upper level signal P1 is input to the motor drive output pulse generation circuit 43, and in the motor drive output pulse generation circuit, the relay drive circuit 45 operates a normal rotation side relay (not shown) for the first time. A pulse is output to the drive circuit 45. The relay drive circuit 45 receives the pulse and operates the relay on the forward rotation side for a unit time.
The movement adjustment drive circuit 9b is rotated forward in units of time.

Therefore, in FIGS. 2 and 3, the brown rice partition plate 11a is moved toward the brown rice area side for a unit time through normal rotation of the screw rod 9a. After all, the brown rice partition plate 11a is automatically movable in accordance with the boundary between the brown rice area and the mixed rice area, and is connected to the brown rice discharge lower a and the mixed rice discharge lower b separated by the brown rice partition plate 11a. To ensure that brown rice and mixed rice are separately discharged.

-1- The movement of the brown rice partition plate 11a is repeated, and the brown rice partition plate 11a comes into contact with the F limit switch 13a.

In this case, if the brown rice partition plate 11a is shifted further toward the brown rice area than the range limited by the upper limit switch 13a, the amount of brown rice discharged will be extremely small, and the oscillating sorting ti
Continuous operation with @ closed becomes impossible. Therefore, the upper limit switch 13'a is activated, and the signal is input to one AND circuit 51a of the control device @15. A signal from the timer 57 is also input to the AND circuit 51a, and when the signal from the upper limit to the switch 13a continues for a predetermined period of time, the AND circuit 51a outputs an output. Therefore, one transistor 53a operates, the relay 55a operates, and the angle drive device 31 is rotated in the normal direction.

Through normal rotation of the rotation spring 6 portion 31a, the two angle adjustment arms rotate clockwise in FIG. 2, and the sorting plate 3 becomes steeply inclined. To the boundary between the brown rice area and the mixed rice area, the brown rice partition plate 11a moves to the mixed rice area side, and correspondingly, the brown rice partition plate 11a moves to the mixed rice area side by an action opposite to that described above. Therefore, the brown rice partition plate 11a is separated from the upper limit switch 13a, the signal from the upper limit switch 13a is not input to the AND circuit 51a, the angle drive device @31 is stopped, and the angle correction of the sorting plate 3 is completed. The movement of the brown rice partition plate 11a is adjusted within a range that allows continuous operation again. Furthermore, when the brown rice partition plate 11a moves toward the mixed rice area and comes into contact with the lower limit switch 13b, the inclination of the sorting plate 3 is relaxed due to the substantially same effect as described above, and the brown rice partition plate 11a is Movement adjustment is performed within a range that allows continuous operation.

Note that this invention is not limited to the above embodiments. For example, in the above embodiment, the paddy partition plate 11b is fixed, but it may be configured to be movable and adjustable like the brown rice partition plate 11a.

As described above, the present invention provides a swinging sorting device that can adjust the swinging angle of a sorting plate by an angle adjustment device, and separates different kinds of sorted grains from the sorted dregs discharge port of the sorting plate so that different kinds of sorted grains are discharged separately. A partition plate is provided which partitions the sorted lees discharge port corresponding to the boundary of refining and is movable along the sorted lees discharge port by driving a movement adjustment device based on a command that detects movement of the boundary of sorting and refining. , a detection device is provided that detects that the partition plate has been adjusted to move within a predetermined range and generates a signal, and upon receiving the output signal of the detection device, the angle is adjusted to adjust the movement of the partition plate within the predetermined range. Since a control device is installed to control the adjustment device, the partition plate can automatically adjust its movement in response to the movement of the boundary between sorting and refinement on the sorting plate. They can be discharged separately and reliably. When the partition plate is adjusted to move more than a predetermined number of times, the control device receives the detection signal from the detection device and issues a command to the angle adjustment device to automatically adjust the inclination angle of the sorting plate. It is possible to forcibly move and correct the boundary between sorted grains by changing the grain size. Therefore, the partition plate is always within a predetermined range:,.

The movement of the machine can be adjusted automatically, and continuous operation can be performed at a constant sorting performance without the partition plate being too far to one side of the sorting and refining of different types and making continuous operation impossible. I can do it.
