[0046] Working principle:

[0047] When using the rice huller with good rice hull removal effect, first, connect the power supply and start motor 12, motor 22, and the exhaust fan 33. Then, add paddy through the feed hopper 101 into the housing 1. At this time, the paddy will fall on the bidirectional spiral conveyor roller 16. Motor 13 drives the upper rotating shaft 15 and the lower rotating shaft 11 to rotate through the belt 18. The upper rotating shaft 15 drives the bidirectional spiral conveyor roller 16 to rotate. The bidirectional spiral conveyor roller 16 spreads the paddy to the front and back sides, ensuring the uniformity of paddy feeding, preventing local accumulation of paddy at the position of the hulling roller 12, and thus preventing blockage of paddy at the positions of the hulling roller 12 and the feed hopper 101. At the same time, it can improve the hulling efficiency of the hulling roller 12 for paddy. With the cooperation of the two linkage gears 14, the two lower rotating shafts 11 drive the corresponding hulling rollers 12 to rotate and perform hulling operations on the paddy. Motor 22 drives the driving gear 23 to rotate. The driving gear 23 drives the driven gear 25 to rotate. The rotation of the driven gear 25 can control the guide block 21 to reciprocate back and forth along the guide port with the cooperation of the support rod 26, thereby controlling the sieve plate 2 to reciprocate back and forth, and then screening the paddy after primary hulling. At the same time, the driven gear 25 drives the bevel gear 1 241 to control the bevel gear 2 243 to rotate through the rotating rod 24. The bevel gear 2 243 drives the rotating pin to control multiple milling rollers 242 to rotate and perform secondary hulling operations on the paddy on the sieve plate 2. With the reciprocating movement of the sieve plate 2, the hulling efficiency of the milling rollers 242 is improved, so that full hulling processing operations of paddy can be realized. The hulled paddy is discharged from the discharge port position. During the process of paddy processing, with the cooperation of the exhaust fan 33, the dust suction pipe 31, the dust suction head 32, and the air outlet pipe 34, rice hulls and impurities such as bran dust during the processing can be extracted and stored above the filter plate 301 in the box under the action of the filter plate 301, so as to ensure the cleanliness of the processed paddy. When it is necessary to discharge the rice hulls and bran dust in the box 3, just pull the handle to open the box door 35. After the discharge is completed, release the handle, and the box door 35 can be reset under the action of the reed 36.

[0048] This rice husk removing effect good hulling machine, through the setting of the bidirectional spiral conveying roller 16, can spread the paddy in the feed hopper 101 to the front and back sides when the upper rotating shaft 15 rotates, so as to ensure the uniformity of feeding, and further avoid the phenomenon of local accumulation of paddy at the position of the hulling roller 12. It can not only prevent the blockage phenomenon of paddy at the positions of the hulling roller 12 and the feed hopper 101, but also improve the hulling processing efficiency of the hulling roller 12 for paddy; through the setting of the grinding roller 242, it can perform secondary hulling operation on the paddy on the sieve plate 2 when the rotating pin rotates, so as to realize the full hulling processing operation of paddy; through the cooperation of the first bevel gear 241, the second bevel gear 243, the support rod 26 and the guide block 21, it can control the reciprocating movement of the sieve plate 2 back and forth when the motor two 22 works, and then discharge the hulled paddy from the right side of the sieve plate 2 and collect it through the discharge port. At the same time, it can leave the hulled rice husks and impurities such as bran dust on the sieve plate 2 and be thrown up with the reciprocating movement of the sieve plate 2, which is convenient for the suction fan 33 to suck the rice husks and impurities such as bran dust into the box body 3 for collection.

[0049] In addition, this rice husk removing effect good hulling machine also has the advantages of compact structure, simple operation and convenient maintenance, can meet the needs of large-scale paddy processing, and improve the paddy processing efficiency and quality.
