Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an automatic cylindrical tilt return device in a grain sorting device for grains of different types in a hulling device.

(Prior Art) Conventionally, the condition for the dissimilar grain sorting device of a rice hulling device is to supply more than a certain amount of grain, and if the amount supplied to the dissimilar grain sorting device is less than a fixed amount, it cannot be sorted. Therefore, in the conventional apparatus, when small grains of rice remain in the machine near the end of the work, the sorting section is tilted to take them out of the machine.

(Problems to be Solved by the Invention) However, in the conventional device, the sorting section was tilted to take out the remaining rice and left as it was, so when restarting work, the sorting section had to be When the grain has to be returned to its original position and the work is restarted, the sorting section is tilted, so the grains flow quickly through the sorting section and can be sorted properly, which is inconvenient.

(Means for Solving the Problem) Therefore, the present invention prevents erroneous operation by automatically returning the cylinder to a horizontal state if the cylinder is tilted when starting the hulling sorting operation. A structure equipped with a hulling section 1, a dissimilar grain sorting section 13 for separating mixed rice, and a vertical movement device 36 for tilting the sorting section 13 to drain out residual rice, is provided with respect to the feed path for the raw unhulled rice. A sensor 51 that is OFF before the raw material is supplied but turns ON when the raw material is supplied, and a sensor 54 that is ON when the sorting section 13 is tilted and OFF when it is horizontal; Sensor 5 is OFF when the power is supplied and ON when the power is not supplied.
2 is provided, and when the sensor 51 is ON, the sensor 54 is ON, and the sensor 52 is OFF, the motor 48 of the vertical device 36 is reversed.

Therefore, on the take-out side 32 side of the cylinder 14, there is a paddy rice take-out port 55.
A paddy rice receiving pipe 56 is provided at the bottom of the paddy rice receiving pipe 5.
A paddy rice conveyor 57 is provided on top of the paddy rice conveyor 57. The returned unhulled rice collected by the unhulled rice conveyor 57 is returned to the return chamber 59 by the thrower 58. 60 is a finished rice take-out receiving trough, 61 is a finished rice conveyor, and 62 is a boss lower. What is the relationship between the unhulled rice sensor 51, the cylindrical tilt sensor 54, and the outflow sensor 52?

Paddy rice detection sensor 51...ON Outflow detection sensor 52...OFF Cylindrical tilt sensor 54...ON When , the motor 48 rotates in reverse.

(effect) Next, we will discuss the effect.

When paddy rice is put into the supply hopper 3, the paddy rice detection sensor 51 detects that the paddy rice is put in and turns on. At this time, rice residue processing is not being performed, and despite this, when the cylinder 14 is tilted, the cylinder tilt sensor 54 is ON, and the outflow sensor 52 detects that grains are being removed from the take-out channel 24. Since there is no leakage, it is OFF, so the vertical movement device 36 is operated and the motor 48 is turned off.
is rotated in the opposite direction to rotate the threaded portion 37 via the sprockets 49 and 50. The screw portion 37 rotates in the opposite direction, and the screw portion 3
Since the pieces 39 and 40 screwed into 7 separate from each other,
The arms 46,47 are tilted to move the bosses 44,45 downward, lowering the feed side 35 of the dissimilar particle sorter 13 into a horizontal position.

Therefore, the unhulled rice loaded into the supply hopper 3 in this state is hulled between the hulling rolls 2 and 2, then wind-selected in the wind-selecting chamber 6, and the rice husk dust, etc. is discharged from the fifth port 12 by the suction blower 11. be done. - Aromas are transported through the first conveyor 7 to the thrower 21
Flows into the supply chamber 20 from the outlet 22 of. Since the switching valve 26 closes the take-out channel 24 by operating the switching operation lever 28, the mixed rice flows into the mixed rice receiving trough 18, is transported laterally by the mixed rice conveyor 19, is supplied into the cylinder 14, and is fed into the pot hole. The rice that is pulled up at step 15 is taken out to the finished rice receiving trough 16.
The finished rice is conveyed sideways by the finished rice conveyor 17, reaches the finished rice conveyor 61 through the finished rice take-out receiving gutter 60, and is then transferred to the finished rice thrower 6? 2. The unhulled rice is taken out from the unhulled rice outlet 55 to the unhulled rice receiving trough 56, and returned from the unhulled rice conveyor 57 to the thrower.
58 and returned to the return chamber 59.

However, when the work is nearing completion, the switching operation lever 28
When the switching valve 26 is rotated around the shaft 25 to close the supply passage 23 and open the take-out passage 24, grains that are about to flow in from the thrower 21 are transferred to the take-out passage 24. It is taken out of the machine. And this extraction channel 24
When the outflow detection sensor 52 detects that the grains are flowing out, it is turned ON and the outflow detection sensor 52 rotates the JZ vertical moving device motor in the forward direction to lift the supply side 35 side of the dissimilar grain sorting section 13.

Therefore, from the unhulled rice outlet 55, there are only unhulled rice 11...
,(*Eh,,Yu0.W1.□56) Distilled paddy rice flows into the return chamber 59 via the conveyor 57 and the thrower 58, and is supplied to the hulling section 1.

As a result, the supply side 35 of the sorting section 13 rose and the grains inside the cylinder 14 flowed out as described above! When the outflow detection sensor 52 detects this, the motor 48 of the vertical movement device 36 is reversely rotated to return the cylinder 14 to the horizontal state.

That is, becomes.

(Effects) As described above, the present invention includes the huller l, the dissimilar grain sorting section 13 that separates mixed rice, and the vertical movement device 36 that tilts the sorting section 13 and drains the remaining rice. In addition, there is a sensor 51 that is OFF before raw material is supplied to the raw material paddy rice supply path, but is turned ON when the raw material is supplied, and a sensor 5 that is ON when the sorting section 13 is tilted and OFF when it is horizontal.
4, and a sensor 52 which is OFF when the supply is being supplied to the sorting section 13 and ON when the supply is not.
When the sensor 51 is ON, the sensor 54 is ON, and the sensor 52 is OFF, the motor 48 of the up-and-down device 36 is reversed to return the sorting section to the horizontal position. The gist of the configuration is as follows: (i) When paddy rice is loaded into the supply hopper 3, the sensor 51 detects the start of work, and at this time, the cylinder tilt sensor 54 detects that the cylinder 14 is tilted. When the outflow detection sensor 5-2 detects and confirms the end of the remaining rice processing, the lowering device 36 automatically operates to return the cylinder 14 to the horizontal state, so that the cylinder 14 remains tilted. It is possible to prevent erroneous operation.

When the residual rice processing is finished, the inside of the cylinder 14 will automatically return, so you can restart the work each time.
This has the effect of eliminating the inconvenience of returning the cylinder 14 to its original position.
