Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic lateral inclination adjustment device for a oscillating specific gravity sorting device for grains.

The oscillating specific gravity sorting device for grains is shown in Figure 1, where 1 is an underframe, 2 and 3 are diagonal rods pivoted on the underframe 1, and the sorting device is placed at the upper end of the diagonal rods 2 and 3. This is a sorting device in which a plate 4 is mounted on a shaft, and an eccentric ring 5 is rotated to make diagonal up and down reciprocating movements in the direction of the arrow W, thereby separating the dissimilar mixed grains on the sorting plate 4.

When this sorting device is viewed from above, grains flow as shown in Figure 2. Therefore, a blank section 8 without grain is formed at the corner of the supply side 6 and the swinging side 7.

This blank area 8 is a wasted area, so if it is extremely large, the efficiency will decrease, and if it is extremely small, the efficiency will increase, but if it is too small, the grain will flow too much to the swinging side 7, and it will be rather sorted. Efficiency will go down.

Therefore, a suitable blank space is automatically formed.

The present invention has a rectangular shape when viewed from above, one side facing each other is a supply side, and the other side with respect to the supply side is a discharge side.
When the direction connecting the supply side and the discharge side is taken as the vertical direction, one side in the horizontal direction that intersects with this is called the swinging side, and the other side of the swinging side is called the swinging side, and the plate surface has countless irregularities. The supply side is higher than the discharge side and tilted vertically, the up-swinging side is higher than the down-swinging side and tilted horizontally, and a rocking device is installed to move the board diagonally up and down from the down-swinging side to the up-swinging side. A configuration of an automatic lateral inclination adjustment device for a grain oscillating specific gravity sorting device, in which a maximum blank area detection sensor and a minimum blank area detection sensor are attached to the swinging side of the sorting plate, and the sensors are connected to a lateral inclination adjustment motor. The main points are as follows.

To explain with a diagram, the sorting plate 4 is formed into a rectangular shape when viewed from above, and one opposing side is the supply side 6.
The other side to the supply side 6 is the discharge side 9, and the direction connecting the supply side 6 and the discharge side 9 is the vertical direction, which is vertically inclined at an α angle. The direction that intersects the vertical direction is the horizontal direction, one side in the horizontal direction is the swinging lower side 7, and the other side of the swinging side 7 is the swinging side 10. It is tilted horizontally at a high β angle. Numerous protrusions 11 facing toward the swinging side 10 are formed on the sorting plate 4. The discharge side 9 is open across the entire width, and the grains flow out from the entire width, but partition plates 12 and 13 are provided in the middle of the discharge side 9, and by partitioning with the partition plates 12 and 13, the unhulled rice outlet 14 and the mixed rice are separated. A take-out port 15 and a brown rice take-out port 16 are respectively formed.

The sorting plates 4 are stacked in multiple stages as shown in FIG. 3, and supply ports 17 are formed at the corners of the supply side 6 and the swinging side 10. The sorting plate 4 is attached to the underframe 1 by diagonal rods 2 and 3, and of the diagonal rods 2 and 3, the lower diagonal rod 3 on the swinging side 10 (a pair of diagonal rods 3 are attached on the front and rear sides) is attached. The pivoting rod 18 can be adjusted up and down, and the upper part of the arm 19 tilted to the opposite side is fixed to the pivoting rod 18.
The upper end of the shape rod 20 is fixed to the lower end of the shape rod 9, and the shape rod 2
0 to a fixed part, and the lower end of the shaped rod 20 is screwed onto the rotating shaft 23 of the forward/reverse motor 22.

However, the grain supplied from the supply port 17 flows out as shown by the arrow in FIG. direction, said lateral slope β
When it becomes loose, it moves in the opposite direction of arrow A, and the detection sensor 25 is attached to the largest blank area, and the detection sensor 26 is attached to the smallest blank area, respectively.

FIG. 4 shows an embodiment in which the sorting device is integrally assembled with a hulling device, in which 27 is a loading hopper of the hulling device, 28 is a hulling section, 29 is a wind selection section, 30 is a suction blower, 31 is an elevator, 32 is a storage tank, 32
34 is a swing sorting device, 35 is a return thrower, and 36 is a finished rice take-out thrower.

FIG. 5 shows the motor 22, the maximum blank area detection sensor 25, and the minimum blank area detection sensor 2.
6 shows a circuit diagram in which the circuits 6 and 6 are connected in a related manner.

Next, we will discuss the effect.

When the hulled rice is supplied to the husking hopper 27, it is hulled by the hulling section 28 and flows into the winnowing section 29, where the lightweight rice grains are suctioned and removed by the suction blower 30, and the hulled brown rice and the hulled unhulled rice are separated. The mixed rice is lifted by an elevator 31, flows into a storage tank 32, and is fed to a distribution supply gutter 3.
3 to the sorting plate 4 of the oscillating specific gravity sorting device 34. The supplied mixed rice flows out from the supply port 17 as shown in Fig. 2, and is subjected to a reciprocating motion that is stirred up from the lower shaking side 7 to the upper shaking side 10 by the rotation of the eccentric wheel 5, and is sorted into unhulled rice. The brown rice flows into the outlet 14, the brown rice flows into the outlet 16, and the unseparated mixed rice in the middle flows into the mixed rice outlet 15. At this time, a blank part 8 is formed at the corner of the supply side 6 and the swinging side 7, but when the blank part 8 becomes maximum, the flow line 24 turns on the minimum blank part detection sensor 25. , the forward/reverse rotation motor 22 is rotated in the normal direction via the angle control control box, and its rotating shaft 23 is rotated to
0 is rotated clockwise in FIG. 3, the arm 19 is brought closer to vertical, the lateral inclination β is increased, and the flow line 24 is moved in the direction of arrow A. When the blank area 8 becomes smaller and the flow line 24 reaches the minimum blank area detection sensor 26, the operation occurs in the reverse order, and the forward/reverse motor 2
2 is reversed to reduce the lateral inclination β.

Conventionally, it is known that the condition of the grain discharged from each outlet is detected and the horizontal inclination of the sorting plate is automatically adjusted. In this case, there was a defect with delayed timing due to mixing of different types of grains.

The present invention has a rectangular shape when viewed from above, one side facing each other is the supply side 6, the other side to the supply side 6 is the discharge side 9, and the direction connecting the supply side 6 and the discharge side 9 is the vertical direction. One side in the horizontal direction that intersects with the oscillating side 7 is the oscillating side 7, and the other side of the oscillating side 7 is the oscillating side 10. The upper swinging side 10 is raised higher than the lower swinging side 7 and is tilted laterally.A swinging device is installed to move diagonally up and down from the lower swinging side 7 toward the upper swinging side 10. A maximum blank area detection sensor 25 and a minimum blank area detection sensor 26 are attached to the swinging side 7, and the sensors 25 and 26 are connected to a motor 22 for adjusting the horizontal inclination. Since the adjustment device automatically adjusts the lateral inclination β of the sorting plate 4 according to the condition of the blank space 8, abnormalities in the lateral inclination β can be detected even before the grain reaches the middle of the sorting plate 4 and is subjected to the sorting action. Since it is detected and adjusted, there is no possibility that different types of grains are mixed and discharged from each outlet, which has the advantage of being able to prevent the defects of the above-mentioned known example.
