Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain dehulling technology, specifically a multifunctional grain dehulling device. Background Technology
[0002] A grain hulling machine can remove the husks from paddy rice to obtain pure brown rice. The grain hulling machine consists of a pair of opposing but unequal rotating rubber rollers. During operation, the paddy rice passes between the two rollers, and the rice passing between the rollers is squeezed, which shreds the rice and thus removes the husk.
[0003] In existing grain hulling machines, the relative distance between the two rubber rollers remains constant during operation. However, the rice grains to be hulled contain grains of different sizes. When the size of the rice grains is smaller than the distance between the rubber rollers, the rice grains will be subjected to less pressure, making it difficult for them to be hulled. When the size of the rice grains is larger than the distance between the rubber rollers, the rice grains will be subjected to greater pressure, making them easier to crush, resulting in poor hulling performance.

The outlet of the hopper 2 is directly above the screening frame 8. The lower inner surface of the shell 1 is fixedly connected to a blower assembly 14 near one edge.

The upper surface of the fixing block 5 is provided with a through threaded hole, and the threaded hole of the fixing block 5 is threadedly connected to the fixing screw.
[0030] Working principle: In use, the distance between the two extrusion rollers 13 is adjusted to a smaller value by adjusting the positions of the two first motors 4. Then, the discharge pipe of the storage frame 10 is blocked by the sliding baffle 3. Then, the first motor 4, the second motor 15, and the blowing assembly 14 are started. The first motor 4 drives the extrusion roller 14 to rotate, and the second motor 15 drives the screening frame 8 to shake back and forth through the gear 18 and the sliding plate 16. Grains are then added to the hopper 2. The grains will fall to the higher position of the screening frame 8. During the back and forth shaking of the screening frame 8, smaller grains will fall out. In the lower collection frame 11, the grains fall between two extrusion rollers 13 and are squeezed. Larger grains remain on the screening frame 8 and slide downwards, thus falling into the storage frame 10. After all the smaller grains have been processed, the distance between the two extrusion rollers 13 is increased, and the sliding baffle 3 is pulled to release the obstruction of the discharge pipe of the storage frame 10. At this time, the larger grains flow into the collection frame 11 and then fall between the two extrusion rollers 13 and are squeezed. These two processes ensure that grains of different sizes are subjected to approximately the same pressure, thus ensuring the dehulling effect.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
