[0002] Rice is a cereal crop of the genus Oryza. Rice is divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice according to rice type. It is divided into conventional rice and hybrid rice according to the seed retention method. There are other classifications. It can be divided into paddy rice and floating rice according to whether it is cultivated without soil; it can be divided into seasonal rice and according to its life cycle; it can be divided into ordinary rice and giant rice of about 2 meters according to its height; and it can be divided into ordinary freshwater rice and seawater rice according to its salt and alkali resistance. At present, rice cleaning machines are usually used to separate impurities in rice seeds.

[0004] By comparing with the existing technologies in related fields, it can be seen that in the process of cleaning rice seeds, the rice seeds are piled in the cleaning machine, and the rice seeds will block the debris and dust, which will affect the efficiency of rice seed cleaning and affect the quality of rice seed cleaning. Utility Model Content

[0005] The purpose of the utility model is to provide a rice seed processing cleaning machine in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A rice seed processing cleaning machine comprises a cleaning box, a lower surface of which is provided with a buffer assembly, a first discharge port, and a second discharge port, a hopper is provided at the upper end of the side of the cleaning box, a third discharge port is provided at the lower end of the side of the cleaning box, a first filter screen, a second filter screen and a material turning assembly are provided in the cleaning box, the material turning assembly is located above the first filter screen and the second filter screen, the first filter screen is located between the first discharge port and the hopper, the first filter screen has a smaller filter hole than the second filter screen, the first filter screen and the second filter screen are connected, the second filter screen is located above the second discharge port, and the second filter screen is connected to the first filter screen. Three discharge ports, adding rice seeds into the cleaning box through the hopper, turning the rice seeds in the cleaning box through the turning component, filtering dust and other fine debris in the rice seeds through the first filter, leading out and collecting the sieved dust through the first discharge port, moving the rice seeds after preliminary screening to the second filter, sieving the rice seeds through the second filter, leading out and collecting the sieved rice seeds through the second discharge port, and large particles of debris are left on the second filter, and the large particles of debris are led out through the third discharge port, thereby completing the cleaning of the rice seeds;

[0008] The turning component includes a motor, a sleeve, and an air inlet valve. The motor and the air inlet valve are respectively arranged on both sides of the cleaning box. The sleeve is rotatably installed in the cleaning box. One end of the sleeve is connected to the output shaft of the motor, and the other end of the sleeve is rotatably connected to the air inlet valve. A spiral blade is arranged on the part of the sleeve located in the cleaning box. The spiral blade is slidably connected to the upper surfaces of the first filter screen and the second filter screen. An air guide groove is arranged in the spiral blade. An air outlet hole is arranged on the surface of the spiral blade. The air guide groove, the air outlet hole and the sleeve are connected. The motor is electrically connected to an external controller, and the air inlet valve is electrically connected to an external hot air device. The motor drives the spiral blade to rotate through the sleeve, and the rice seeds in the cleaning box are turned and transported through the spiral blade, so that the rice The dust in the seeds can be better screened out, the dust in the rice seeds is screened out through the first filter, the rice seeds on the first filter are moved to the second filter through the spiral blades, the rice seeds are screened out through the second filter, and the large and medium-sized debris in the rice seeds are left on the second filter. The spiral blades guide the debris left on the second filter through the third discharge port. At the same time, the external hot air device blows hot air into the rice seeds through the air inlet valve, the air guide groove and the air outlet, so as to dry the rice seeds, make the rice seeds more resistant to storage, and can blow the debris in the rice seeds, so that the rice seeds and dust and debris can be better separated, thereby improving the efficiency of rice seed cleaning.

[0009] Furthermore, the buffer assembly includes a damping rod, which is arranged on the lower surface of the cleaning box. A base plate is arranged at the lower end of the damping rod. A spring is sleeved on the damping rod. The damping rod is supported by the base plate to improve the stability of the damping rod when supporting the cleaning box. When rice seeds are poured into the cleaning box and the spiral blades rotate, the cleaning box will be subjected to a certain impact force.

The barrier curtain is used to shield the connection between the hopper and the cleaning box, thereby preventing dust in the cleaning box from escaping and avoiding pollution to the environment.

[0012] Furthermore, it also includes a first dust hood, a second dust hood, and a connecting valve. The first dust hood and the second dust hood are both installed in the cleaning box. There are two connecting valves in total and both are installed on the cleaning box. The two connecting valves are respectively connected to the first dust hood and the second dust hood. The two connecting valves are both connected to an external dust suction device. The external dust suction device absorbs and processes flying dust generated during the rice cleaning process in the cleaning box through the connecting valve, the first dust hood and the second dust hood, thereby effectively preventing dust during the cleaning process from escaping into the environment and causing pollution to the environment.

[0013] Furthermore, it also includes a hanging plate and a limiting plate. The hanging plate is L-shaped and is arranged on both sides of the lower surface of the cleaning box. The limiting plate is arranged on the lower surface of the cleaning box, and the limiting plate is located directly below the connection between the first filter screen and the second filter screen. The hanging plate is used to support and place the receiving box, so as to facilitate the collection of dust discharged from the first discharge port and rice seeds discharged from the second discharge port. The receiving box on the hanging plate is limited by the limiting plate, so that the receiving box can be installed in place and the dust discharged from the first discharge port and the rice seeds discharged from the second discharge port are prevented from mixing together.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] 1. The motor and the casing drive the spiral blades to turn and transport the rice seeds, so that the first filter and the second filter can better filter and clean the rice seeds, avoiding the accumulation of the cleaned rice seeds affecting the screening of debris. At the same time, the external hot air device blows hot air into the rice seeds through the air inlet valve, the air guide groove and the air outlet, thereby blowing the debris in the rice seeds, so that the rice seeds and dust and debris can be better separated, the efficiency and quality of rice seed cleaning are improved, and the rice seeds are ensured to be neat after cleaning.

[0016] 2. The external hot air device blows hot air into the rice seeds through the air inlet valve, air guide grooves and air outlet holes, blows out the dust in the rice seeds and dries the rice seeds at the same time, making the rice seeds more durable in storage.
