Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adjusting device for adjusting the rotational speed of a rotary separator mainly used in a grain sorting section of a rice huller to an appropriate rotational speed.

Conventionally, in a rotary separator that separates grains by forming a large number of pot holes on the inner circumferential surface and scooping out the grains through the pot holes, it is relatively easy to separate grains (highly) if they are grains or small grains. When the grains are scooped up and are large, they have the characteristic of being relatively stable.

Therefore, when the grains are small, if the separator rotation is not slightly reduced, unhulled rice will be mixed into the brown rice, and when the grains are large, the efficiency will be reduced unless the separator rotation is increased. It was decided not to.

Therefore, in the present invention, a rotary separator is provided with a sensing device for detecting the upper y state of the grains, a rotational speed adjusting device is attached to the rotary separator, and the sensing device and the adjusting device are connected to each other to detect the upper y state of the grains. The rotary separator is equipped with a rotary separator adjustment device that automatically changes the rotation speed of the rotary separator according to the rising state, and a large grain sensing device and a small grain sensing device inside the rotary separator. A rotation speed adjustment device is provided, and the rotation speed of the rotary separator is adjusted so that the rotation speed of the rotary separator becomes the same when the small grain sensing device senses the rain, and when the large grain sensing device senses the rain sensing device and the adjustment device. This is a rotary separator adjustment device configured to speed up the rotation of the rotary separator, and as described above, even if there are large or small grains, it always rotates at an appropriate rotation speed and discriminates. This is what I did.

To explain the function and effect of the rotary separator of the hulling machine of the present invention having the following configuration, first, in the first embodiment, when the raw material paddy is supplied to the loading hopper 1, the raw material paddy flows down and enters the hulling chamber. 2, the hulled rice is removed by the hulling rolls 3, 3, and the hulled material flows down the downflow gutter 5 and flows into the winnowing chamber 4. In the air selection chamber 4, the selection air generated by the suction fan 6 and the pressure fan 31 is flowing, so that the light rice husks are sucked, flow through the discharge pipe 7, and are discharged to the outside from the exhaust port 8. The immature grains flow into the immature grain receiving trough 10 and are discharged to the outside by the conveyor 10a. The mixed rice of brown rice and unhulled rice flows into the receiving gutter 9, and is transferred to the conveyor 9a and the conveyor belt 1.
The inflow of the r portion of 4 [1] is fed to the grain f? by the action of the thrower 14. It flows into the hopper 13 of lil 2.

Then, from the hopper 13, the rotary separator 15
supplied within. When the motor rotates and the belt 38 rotates, the rotary separator 15 moves to the pulley 34.
．． 35 rotates the rotating shafts 32 and 33, so that the grains fit into the pot holes 16 and, when the grains are small, reach the small grain sensing device 23 located far away.
When the grain is large, the large grain sensing device 22 is raised. It is most logical for the degree of ``-1'' to rise to an intermediate position between the large particle sensing device 22 and the small particle sensing device 23, and when it rises to the small particle sensing device 23, the rotation is a little too fast. Therefore, the rotation is adjusted to become slower, and if the rotation only rises to the large particle sensing device 22, the rotation is a little too slow, so the adjustment is made to become faster to avoid inefficiency.

That is, when grains are put into the small grain sensing device 23, the sensing plate 26 therein is pushed down against the elasticity of the spring 290 to turn on the switch 27, thereby turning on the forward/reverse motor 4.
0 to reverse the rotation screw 41, move the top 42 upward to weaken the tension pulley 39 against the belt 38, increase the effective diameter of the speed change pulley 37, and increase the rotation of the rotary separator 15. Slow down.

On the other hand, when grains are introduced into the large grain sensing device 22, the sensing plate 24 inside is pushed down against the elasticity of the screw 28, the switch 25 is turned on, and the forward/reverse motor 40 is energized to rotate the rotating screw. 41 is rotated in the normal direction, and the top 42 is moved downward to make the tension pulley 39 strongly contact with the belt 38, to reduce the effective diameter of the speed change pulley 37, and to rotate the rotary separator 15 by 1r.

In this way, the brown rice is collected in the first receiving trough 18, transported horizontally by the first screw container 17, taken out to the tithe-1-rice drop opening 51, and then collected from the tithe-rice receiving trough 49. - Extracted as rice.

1. Also, the mixed rice is taken out to the receiving trough 52, transported horizontally by the compare 53, and flows into the mixed rice receiving trough 9 from the mixed rice drop port 50,
The waste is returned to the hopper 13 by the thrower 14 and reprocessed.

As already mentioned, conventional rotary separators have a large number of potholes formed on the inner circumferential surface and use the potholes to scoop out the grains to sort the grains. It had the characteristic that it scooped up well (high), and when the grain was large, it did not rise comparatively.

Therefore, when the grains are small, the rotation of the separator must be slowed down a little, otherwise unhulled rice will be mixed into the brown rice, and when the grains are large, the rotation of the separator must be slowed down to reduce efficiency. It was decided that the top was not available.

2 However, in the present invention, the rotary separator 15 is provided with sensing devices 22 and 23 for detecting the above grain condition, and the rotary separator 5 is equipped with a rotation speed adjusting device, and the sensing devices 22 and 23 and the Connect the regulator to adjust the grain's -J'? A rotary separator adjusting device that automatically changes the rotation speed of the rotary separator 15 according to the state, and a large grain sensing device 22 and a small grain sensing device 23 are provided in the rotary separator 15, and the rotary The separator 15 is provided with a rotation speed adjusting device, and the rain sensing device 22
- When the small grain sensing device 23 senses the adjustment device 23 and the adjustment device, the rotation of the rotary separator 15 is slowed down, and when the large grain sensing device 232 senses it, the rotation of the rotary separator 15 is slowed down. The rotary separator adjustment device is configured so that the temperature increases quickly, and when it rises to the small particle sensing device 23,
The rotation is a little too fast, so adjust it to slow it down, and if it only reaches the large grain sensor 22, the rotation is a little too slow, so adjust it to speed up. 22 and the small particle sensing device 23, the most ideal and efficient sorting can be achieved.
