Description

Technical Field

[0001] The utility model relates to a moving sieve not included in other categories, for example, the technical field of a shaking, reciprocating, rocking, inclined or oscillating sieve, and particularly to a stone removal device for rice processing. Background Art

[0002] During the rice processing, since the rice is mixed with small stones, a screening device is often used to remove these small stones. A Chinese utility model patent, authorization announcement number "CN220277574U", discloses a device for removing impurities and stones, including a processing box, wherein an impurity removal mechanism is provided inside the processing box, and the impurity removal mechanism includes a driving mechanism and a screening mechanism.

[0003] The above technical scheme is provided with an impurity removal mechanism, and utilizes a screening mechanism to screen the rice using two groups of screening nets of different sizes. The second screening net uses a larger mesh for screening, and can remove large particles of impurities in the rice. The first screening net uses a smaller mesh for screening, and can remove small particles of impurities in the rice, so that the rice impurity removal and stone removal effect is better, and it is not easy to be mixed with impurities in the rice, so that users can use it with confidence and reduce the burden on users. At the same time, a hair dryer and an exhaust fan are used in combination to blow up and collect dust or skin attached to the surface of the rice, so that the surface of the rice is cleaner and tidier. Since the exhaust position of the exhaust fan is relatively fixed, the rice grains far away from the exhaust fan are not easily cleaned by the exhaust fan, which leads to the phenomenon that the exhaust fan has a poor cleaning effect on the rice grains. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a stone removing device for rice processing, which can solve the problem that the exhaust position of the exhaust fan is relatively fixed, resulting in that rice grains far away from the exhaust fan are not easily cleaned by the exhaust fan, thereby resulting in the exhaust fan having a poor cleaning effect on the rice grains.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stone removal device for rice processing, comprising a processing shell;

[0006] The screening assembly is arranged in the processing shell, and the screening assembly includes four vibration motors, four grooves, four springs and two screening nets.

[0012] Preferably, the inner surface of the threaded sleeve is threadedly connected to the surface of the threaded rod, and the threaded rod rotates to penetrate the bracket outside the processing shell.

[0013] Preferably, the motor screw is mounted on an external bracket of the processing housing, and the motor gear key pin is mounted on an output shaft of the motor.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The rice processing stone removing device is provided with a motor and a vibration motor in the blowing assembly and the screening assembly. The vibration motor can drive the rice grains to move continuously, thereby assisting the blowing head to evenly clean the entire rice grains. The start of the motor drives the blowing head to move to blow the rice grains on the surface of the screening net. The movement of the blowing head ensures that the rice grains on the screening net can be cleaned by the wind blown by the blower, that is, the cleaning range of the blowing head is increased, and the cleaning effect of the rice grains is ensured.

[0018] (2) The rice processing stone removal device is provided with two screening nets in the screening assembly.
