Description

[Detailed explanation of the idea] The present invention relates to an oscillating sorting rice huller.

The oscillating sorting device has an uneven fluid friction plate surface, and the sorting plate is configured to swing back and forth diagonally upward from the bottom to separate out the mixed grains present on the sorting plate. The structure is such that grains with heavy specific gravity are shaken up to the shaking side, and grains with light specific gravity are shifted to the shaking down side.

In other words, this is a separating and sorting method in which grains with a heavy specific gravity are first shaken upwards by diagonally vertically swinging a sorting plate serving as a fluid friction surface, and grains with a light specific gravity are shifted to the opposite side.

Although the conventional swinging sorting device was used in combination with the hulling device, it was difficult to absorb the swinging reaction force of the swinging sorting device. Even if a dynamic sorting device is installed, the rice hulling device cannot absorb the reaction force of the oscillating sorting device, so a separate structure must be used, or the overall structure must be made large enough to absorb the reaction force. However, a device in which the swing sorting device and the hulling device were integrated had to be larger than necessary, and the user suffered various disadvantages in actual use.

The present invention can eliminate the above-mentioned drawbacks, and it consists of a swinging sorting device in which the swinging mechanism is constructed so that the sorting board moves diagonally upward in a reciprocating straight line, which is different from that of the conventional swinging sorting device. Rather than sorting by the oscillating motion of the circular arc trajectory, it separates brown rice, paddy, and a mixture of both by linear movement in diagonal up and down directions, so the reaction force is extremely small, and it looks like the machine is jumping up. As a result, the overall structure that integrates the hulling device and the oscillating sorting device can be made very compact.Moreover, since the vibration has been drastically reduced, the strength of the entire machine body has naturally been increased, and the oscillating mechanism has become simpler. As a result, it has become possible to reduce costs and at the same time downsize the oscillating sorting device itself.As a result, the adjustment device that changes the angle of the oscillating sorting device can also function satisfactorily with a simple configuration. It has become.

The following description will be given based on the embodiment shown in the drawings. Reference numeral 1 denotes a hulling device, with a hulling roll 2 mounted above one side, and a storage chamber for a motor 5 which also serves as a suction passage for a cross-air passage 4 connected to a suction winch 6 at the bottom. This is provided.

Reference numeral 7.8 denotes a receiving trough for unhulled brown rice and a receiving trough for scrap rice, which are provided in the cross wind path and are connected to the screw conveyor 9 and the scrap rice outlet 10, respectively.

3 is a supply hopper. A swinging sorting device is placed on the upper part of the lower table 12 that houses the ventilation passage 4.

In this swing sorting device, a holding frame 19 that holds the sorting board 1 reciprocates in a straight line along the tilt angle α on a movable frame 13 that is pivotally supported 14 so that the tilt angle α in the diagonal vertical direction can be adjusted. The grains on one side of the sorting board are separated and sorted as described above.

That is, a rotating shaft 15 and an angle support shaft 16 are mounted on the movable frame 13, and an eccentric ring 20 is mounted on the rotating shaft 15, and an L-shaped rod 21 is pivotally mounted on the rotating shaft 15 so that the included angle of the two sides can be changed. is installed.

Reference numeral 17 denotes a substantially J-shaped rail fixed to the upper part of the movable frame 13, on which a roller 18, which is pivoted on a holding frame 19 holding the sorting board 1, moves.

This roller 18 is connected to one end of an L-shaped rod 21, and the rotation of the eccentric wheel 20 causes the sorting board 1 to reciprocate on the movable frame 13 along the inclination angle α via the roller 18.

The sorting board 1 is tilted to the same side, smaller than the inclination angle α of the movable frame 13, and in FIGS. 1 and 2, the opposite side is the supply side, and the front side is the discharge side, and the supply side is mounted higher than the discharge side. There is.

Also, on the swinging side of the sorting board 1 and on the discharge side, there is an outlet 31 for taking out unhulled rice.
A brown rice outlet 1132 is provided on the shaking side and a discharge side, respectively, and a mixed grain outlet 33 is provided in the middle.

34 is a discharge port for brown rice, 35 is a discharge port for mixed grains and is connected to the mixed rice hopper 30, and 36 is a discharge port for unhulled rice that opens into the supply hopper 3.

The inclination angle of the sorting board 11 is preferably 5° to 15°, and the inclination angle of the movable frame 13 is preferably 15° to 25°.

22 is the tilt adjustment handle of the movable frame and the bevel gear 23°2
4, the angle adjustment arm 25 is raised or lowered to raise or lower the angle support shaft 16 of the movable frame 13, and the movable frame 13 rotates about the pivot shaft 14 to change the inclination angle α.

At the same time, the inclination angle of the sorting board 1 moving on the movable frame 13 is also changed.

Now, when the various parts are operated to supply unhulled rice to the supply hopper 3, it is deweighed by the hulling roll 2 in the hulling device 1, and then
The mixed grains of unhulled rice and deweighed brown rice are conveyed to the - side by the screw conveyor 9 and stored in the mixed rice hopper 30 from the mixed rice discharge port 35.

When a certain amount of water has accumulated, the shutter (not shown) is opened and the material is fed onto the sorting board 11.The roller 18 of the sorting board 11 reciprocates in a straight line diagonally up and down on the movable frame 13 set at the inclination angle α, and the shaker side is fed to the sorting board 11. The grains are sorted by shaking so that the brown rice is distributed to the side and the unhulled rice is distributed to the shaking side, and the mixed grains are located in the middle.

The brown rice that has drifted toward the shaking side is then taken out of the machine through the brown rice outlet 32 and the brown rice outlet 34.

The unhulled rice drifting toward the shaking side is circulated from the unhulled rice take-out port 31 to the unhulled rice discharge port 36 to the supply hopper 3, and passes through the hulling device 1 again.

The mixed grain taken out from the mixed grain outlet 33 is sent to one side by the screw conveyor 9, supplied to the mixed rice hopper 30 from the mixed rice discharge port 35, and is sorted again by the sorting board 1.

In actual sorting work, it is necessary to change the angle of the sorting plate as appropriate depending on the type of grain, moisture content, etc., and set the best slope. As described above, as the roller 18 linearly reciprocates on the rail 17 which is installed obliquely at an inclination angle α in the direction perpendicular to the suction winch axis, the sorting board 11 is swung up toward the suction winch 6 side, and the hulling roll 2 Since the swinging sorting device is mounted above the cross-wind passage 4 so that it can be swung down to the side, the swinging mechanism is extremely simple and can be configured to be compact and lightweight. The adjustment device that supports the grain and adjusts and changes the angle of inclination α can now be constructed to be simple, lightweight, and compact, making it possible to provide an inexpensive oscillating sorting rice huller with fewer failures. It is something.
