Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automatic adjustment device for a rotary type different grain sorting device in a hulling device.

(Prior Art) Conventionally, some rice hulling devices are equipped with a rotary type different grain sorting device. This device supplies a mixed rice mixture into a rotating cylinder with countless potholes formed on its inner surface, scoops up the finished rice (brown rice) in the lower layer from the potholes, and sends it to a finished rice receiving trough installed inside the rotating tube. The paddy rice is taken out from the inside and the unhulled rice is discharged from the other end.

In order for this grain sorting device to perform a good job of sorting mixed rice of different types, it is necessary to ensure that there is no excess or shortage of grains fed into the rotating cylinder. A sensor was provided, and the detection sensor and the control valve were linked by a shaft, so that when the amount was large, the control valve was closed, and when the amount was small, the control valve was opened.

(Problem to be solved by the invention) However, although the thickness of the grain stack must be detected sensitively by the detection sensor, the flow stack may break if a small amount of pressure is applied to the flow stack. Unfortunately, accurate detection was not possible. Therefore, a balance weight is installed to ensure that the flow stack is not disrupted as much as possible so that it operates more sensitively. However, the installation of the balance weight causes another drawback, ie, the deflection of the shaft, which is also solved by the present invention.

(Means for Solving the Problems) Therefore, the present invention provides a feeding control valve 4 in the hulling section 1 to control the flow to the supply side 29 in the horizontal shaft rotating cylinder 14 of the rotary type dissimilar grain sorting section 13. A detection sensor 31 for detecting the thickness of the laminated layer 30 is provided, and the sensor 31

A drop opening is formed on the starting end side 29 of 5.

Therefore, on the rotation rising side 22 of the starting end side 29, there is a detection sensor 31 that moves up and down depending on the thickness of the flow stack 30.
will be established. The shape of the sensor 31 is formed by bending the lower end into a dogleg shape, as shown in FIG. The upper end 34 of the detection sensor 31 is fixed to a shaft 35, which traverses the inside of the rotary cylinder 14, and one end is pivotally attached to the side plate 32 on the starting end side 29 of the dissimilar grain sorting section 13, and the other end is attached on the terminal end side. It penetrates the side plate 33 of 18 and protrudes outward, and its end is pivoted to the vertical part 48 of the auxiliary bearing 42. The auxiliary bearing 42 has an upper horizontal plate 43 and a lower horizontal plate 44 formed in parallel, a vertical shaft 45 is inserted into these, one side of the horizontal plates 43 and 44 is fixed by a vertical plate 46, and the vertical plate 46 is Side plate 5 of supply chamber 28
It sticks to 4. A vertical portion 48 is provided on the other side of the horizontal plate 43.

(effect) Next, we will discuss the effect.

When unhulled rice is supplied to the supply hopper 2 of the hulling section 1, the amount of unloaded rice is adjusted by the loading control valve 4, and the unhulled rice is supplied to the hulling rolls 5, 5, where it is hulled and falls into the wind sorting section 6. The rice husks are discharged from the exhaust pipe 8 by the suction air of the suction blower 7, the immature rice falls into the immature rice receiving trough 12, and is taken out by the immature rice conveyor 10. The mixed rice falls into the mixed rice receiving trough 11, is taken out by the mixed rice conveyor 9, is fried by the thrower 27 into the supply chamber 28, is supplied from the supply chamber 28 to the mixed rice supply/recovery trough 25, and is transferred to the mixed rice supply spiral. 26 and is supplied into the horizontally rotating cylinder 14 through a droplet formed on the starting end side 29. Since the horizontal shaft rotating cylinder 14 is rotating clockwise in FIG. 4, the grains form a flowing layer 30 and are biased toward the rotation rising side 22, and the brown rice in the lower layer is pulled up through the pot hole 15 and taken out to the finished rice receiving trough 16. The finished rice is transferred to the terminal side 18 by the finished rice conveyor 17, falls from the take-out flow gutter 19 into the finished rice take-out gutter 20, is transported horizontally by the finished rice take-out conveyor 21, and is taken out by the finished rice thrower 57. Paddy rice is paddy returning road 58
The paddy is returned to the paddy return chamber 60 by the thrower 59 for reprocessing.

When the number of grains supplied to the starting end side 29 of the horizontal shaft rotating cylinder 14 increases, the flow stacking layer 30 pushes up the lower end of the detection sensor 31 in the direction B, rotates the shaft 35 in the direction B, and the arm 36 The upper end of the bell crank 38 is rotated horizontally in the direction A by rotating the upper end about the shaft 35 in the direction A. A rod 49 is pivotally connected to the other end of the bell crank 38, and the rod 49 is attached to the arm 4.
Since the arm 40 rotates the shaft 41, the lower end of the feed control valve 4 rotates in the direction B, thereby adjusting the supply amount to a smaller value.

On the other hand, when the number of grains supplied to the starting end side 29 of the horizontal rotating cylinder 14 decreases, the lower end of the detection sensor 31 rotates the shaft 35, and the arm 36, rod 37, bell crank 38, rod 49, and 4
0, the lower end of the feeding control valve 4 is rotated in the opposite direction via the shaft 41 to increase the supply amount.

(Effects) As described above, the present invention provides the feeding control valve 4 in the hulling section 1, and detects the thickness of the flowing layer 30 on the supply side 29 in the horizontal shaft rotating cylinder 14 of the rotary type dissimilar grain sorting section 13. A detection sensor 31 is provided, and the shaft 35 of the sensor 31 is made to protrude outside from the side wall 33 of the different grain sorting section 13, and the shaft 35 of the sensor 31 is made to protrude outside from the side wall 33 of the dissimilar grain sorting section 13.
A balance weight 50 is attached to a portion of the shaft 35 that protrudes from the side wall 33, and the tip of the shaft 35 that protrudes further from the balance weight 50 is connected to the side wall 33 side. Since this is an automatic adjustment device for the rotary type different grain sorting device in the hulling device, which is supported by an auxiliary bearing 42 fixed to the Even if the balance weight 50 is provided instead, the shaft 35 will not be deflected, and there will be an effect that the shaft 35 can be operated accurately and the sorting efficiency can be improved.
