Technical Field

[0001] The utility model relates to the technical field of rice grinding devices, and particularly relates to a rice grinding device with an impurity removal mechanism. Background Technique

[0002] A rice grinding device is a device used to grind paddy into rice. During the grinding process, after the paddy is subjected to processes such as shelling and threshing, it enters the grinding mechanism for grinding, removing parts such as the bran layer and wheat bran on the outer layer of the paddy, and at the same time retaining the rice.

[0003] The rice grinding device plays an important role in paddy processing and can effectively improve the processing quality and output of rice. However, there are still certain problems: the impurity removal efficiency and quality of traditional rice grinding devices are lacking, and the impurity removal efficiency cannot keep up with the grinding efficiency. Therefore, in view of the above current situation, there is an urgent need to develop a rice grinding device with an impurity removal mechanism to overcome the deficiencies in current practical applications and meet the current needs. Summary of the Utility Model

The vibrating sieve is designed with a long stroke to provide a sufficient screening stroke distance for the rice.

[0009] Preferably, there are multiple groups of buffer partitions and they are equidistantly distributed. The buffer partitions are provided with several equidistantly distributed inverted trapezoidal grooves. Their special notch design can prevent the falling rice from being blocked and allow it to continue to fall after decelerating the falling rice.

The vibrating feeding method can ensure the even feeding of rice and make the subsequent impurity removal effect more stable.

[0028] Preferably, the wind impurity removal mechanism 20 includes a cabinet 201, a blower 202 installed on one side of the cabinet 201 for providing impurity removal power, a buffer partition 203 installed inside the cabinet 201 for slowing down the falling speed of rice, an impurity removal slot 204 installed on one side of the cabinet 201 and communicating with the interior of the cabinet 201 for receiving impurities separated from the rice by wind, a waste discharge channel 205 installed at the end of the impurity removal slot 204 for discharging rice impurities, and a collection trough 206 installed at the bottom of the cabinet 201 for receiving the rice after wind impurity removal and guiding it to the bottom vibrating screen 40.

[0029] Preferably, the vibrating screen 40 includes a vibrating screen 402 installed at the bottom edge of the base 30 for vibrating and screening the rice led out from the bottom of the collection trough 206, a second vibrating motor 401 installed inside the base 30 for driving the vibrating screen 402 to operate, a waste discharge trough 403 installed at the bottom of the vibrating screen 402 for receiving the screened rice impurities or small granular rice, and a collection hopper 404 installed at the end of the vibrating screen 402 for receiving the qualified rice screened by the vibrating screen 402. The vibrating screen 402 is designed with a long stroke to provide a sufficient screening distance for rice.

[0030] Preferably, there are multiple groups of buffer partitions 203 and they are equally spaced. The buffer partitions 203 are provided with a number of equally spaced inverted trapezoidal slots 2031. Their special slot design can prevent the falling rice from being blocked and allow it to continue to fall after decelerating the falling rice.

[0031] Preferably, the vibrating feeding mechanism 10, the wind impurity removal mechanism 20, and the vibrating screen 40 are all provided with three groups and are arranged in parallel. Multiple groups of impurity removal and screening mechanisms can improve the rice screening efficiency.

The impurities in the rice are blown into the impurity removal slot 204 by the wind force of the blower 202, and finally discharged through the impurity discharge channel 205. The rice after wind force impurity removal converges into the bottom collection tank 206, and then is guided to the oscillating sieve 402. The second oscillating motor 401 drives it to oscillate. The impurities and broken rice in the rice fall through the screening holes of the oscillating sieve 402 into the lower impurity discharge tank 403. Finally, the screened rice is introduced into the grinder 50 through the collection hopper 404 at the end for grinding.
