DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a rice grinder, including a column 20 and a motor cover 62 fixedly installed on the top of the column 20. A motor 60 is provided inside the motor cover 62. The motor 60 is arranged inside the motor cover 62 to perform dust-proof treatment on the motor 60 to prevent fine particles such as rice powder from entering the inside of the motor 60. A cavity 70 is provided at the bottom of the motor cover 62. One side of the cavity 70 is fixedly connected to the side surface of the column 20. A motor rotating shaft 61 penetrates through the inside of the cavity 70. The output end of the motor 60 is connected to the motor rotating shaft 61;

[0022] Inside the cavity 70, a blade 41, a filter screen 42, a moving grinding plate 51, and a static grinding plate 52 are concentrically arranged from top to bottom. The blade 41 is fixedly installed on the motor rotating shaft 61. The outside of the filter screen 42 is fixedly installed on the inner wall of the cavity 70, and a circular hole for penetrating the motor rotating shaft 61 is provided at the center of the filter screen 42. The moving grinding plate 51 is fixedly installed on the motor rotating shaft 61. The static grinding plate 52 is fixedly connected to the bottom of the cavity 70 and is flush with the bottom of the cavity 70. The blade 41 is used to quickly break the rice, and then it enters between the moving grinding plate 51 and the static grinding plate 52 through the filter screen 42 for fine grinding. The moving grinding plate 51 divides the cavity 70 into a crushing cavity 40 and a grinding cavity 50 located directly below the crushing cavity 40. The static grinding plate 52 is threadedly installed with the bottom of the cavity 70, which is convenient for later disassembly and cleaning of the inside of the machine.

[0023] Among them, a feed pipe 31 is provided at the top of the side of the crushing cavity 40 away from the column 20. A feed hopper 30 is provided at the top end of the feed pipe 31. The feed hopper 30 communicates with the crushing cavity 40 through the feed pipe 31. The user pours the rice to be ground into the feed hopper 30, and then passes through a section of the feed pipe 31 to control the flow rate and ensure that the rice enters the crushing cavity 40 at a consistent flow rate.

[0024] Among them, the lower arc surface of the moving grinding plate 51 is provided with evenly distributed inner grinding teeth 55, and the upper arc surface of the static grinding plate 52 is provided with evenly distributed outer grinding teeth 56. The inner grinding teeth 55 and the outer grinding teeth 56 cooperate and squeeze to fully grind the food raw materials by the mutual extrusion between the inner grinding teeth 55 and the outer grinding teeth 56, effectively avoiding the situation of incomplete grinding.

[0025] Among them, a circle of blanking ports 53 is provided on the moving grinding plate 51 close to the motor rotating shaft 61. After the rice is broken by the blade and then passes through the filter screen, the fallen rice falls into the lower grinding cavity 50 through the blanking ports 53 for continuous extrusion and grinding.

[0026] Among them, a hollowed-out groove 54 is provided at the edge of the static grinding plate 52, and a discharge hopper 80 is provided at the bottom of the static grinding plate 52. An inclined discharge port 81 runs through the bottom end of the discharge hopper 80. The inner grinding teeth 55 on the moving grinding plate 51 and the outer grinding teeth 56 on the static grinding plate 52 jointly act to extrude and grind small particles. The ground rice flour is extruded to the edge of the static grinding plate 52 and falls into the discharge hopper 80 through the hollowed-out groove 54.

[0027] Among them, a support plate 21 is fixedly connected to the bottom of the discharge port. One side of the support plate 21 is fixedly connected to the column 20. The discharge port 81 is inclined to facilitate the falling of the rice flour. For the stability of the overall structure, the discharge port 81 is embedded in the support plate 21.

[0028] Among them, the bottom of the column 20 is fixedly connected to a base 10. A rice flour box 90 is provided on the upper surface of the base 10. The rice flour box 90 is located below the discharge port 81. The rice flour box 90 can be taken separately to facilitate the transfer of the rice flour in the rice flour box 90.

[0029] Working principle: When in use, the user pours the rice to be ground into the feed hopper 30. The rice in the feed hopper 30 slides down the feed pipe 31 to the crushing chamber 40. The blade 41 provided in the crushing chamber 40 breaks the rice. The broken rice passes through the filter screen 42. The large particles that do not pass through the filter screen 42 continue to be broken. The small particles that pass through the filter screen 42 fall into the grinding chamber 50 through the discharge opening 53. The inner grinding teeth 55 on the moving grinding plate 51 and the outer grinding teeth 56 on the static grinding plate 52 jointly act to extrude and grind the small particles. The ground rice flour is extruded to the edge of the static grinding plate 52 and falls into the discharge hopper 80 through the hollowed-out groove 54. The rice flour in the discharge hopper 80 is then collected in the rice flour box 90 through the discharge port 81. After the rice is effectively broken and then extruded and ground, the problems of low grinding fineness and uneven grinding are effectively solved.

[0030] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.
