[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 In this embodiment: a mixing and stirring device for rice processing includes a feeding box 4, and a screening and cleaning component is provided inside the feeding box 4;

[0025] The screening and cleaning assembly includes two feed inlets 6, which are fixedly connected to the top of the feed box 4. Screen plates 15 are slidably connected to both sides of the inside of the feed box 4. A guide plate 16 is fixedly connected to the bottom of the screen plates 15. Two evenly distributed steel pipes 25 are fixedly connected to the inner side walls of the feed box 4. Two evenly distributed reciprocating screws 24 are rotatably connected to the inner side walls of the feed box 4. Scrapers 23 are slidably connected to the outer circumference of both steel pipes 25. The two reciprocating screws 24 are threadedly connected to the two scrapers 23. Two evenly distributed motors 14 are fixedly connected to one outer side wall of the feed box 4. The output ends of the two motors 14 are fixedly connected to one end of each of the two reciprocating screws 24. Slag discharge ports 3 are provided on both sides of the feed box 4. A stirring assembly is provided at the bottom of the feed box 4.

[0026] Specifically, the top of the feeding box 4 is equipped with two feeding ports 6, which facilitate the simultaneous feeding of different materials. The sieve plates 15, which are slidably connected to both sides inside, can perform preliminary screening of the incoming rice and other materials, effectively removing larger particles and ensuring the purity of the materials entering the mixing stage. The guide plate 16 at the bottom of the sieve plate 15 can guide the screened impurities to the discharge device. The steel pipes 25 on both sides of the inner side wall of the feeding box 4 cooperate with the scraper 23. The motor 24 drives the reciprocating screw 24 to rotate, which causes the scraper 23 to slide on the steel pipes 25, which can promptly clear the blockages on the sieve plate 15, ensuring that the screening process is continuous and efficient, and providing a guarantee for the uniformity of subsequent mixing.

[0027] refer to Figure 3 and Figure 4 In this embodiment, the stirring assembly includes a stirring tank 2, which is fixedly connected to the bottom of the feeding box 4. A motor 5 is fixedly connected to the top of the feeding box 4. A transmission rod 17 is fixedly connected to the output end of the motor 5. The transmission rod 17 passes through the feeding box 4. Multiple evenly distributed stirring paddles 22 are fixedly connected to the outer periphery of the transmission rod 17. Multiple evenly distributed telescopic rods 18 are fixedly connected to the outer periphery of the transmission rod 17. A spring 19 is sleeved on the outer periphery of the telescopic rod 18 away from the transmission rod 17. A connecting rod 20 is fixedly connected to the outer periphery of the telescopic rod 18 away from the transmission rod 17. A scraper 21 is fixedly connected to the outer periphery of the connecting rod 20 near the inner wall of the stirring tank 2.

[0028] Specifically, the mixing tank 2 is fixed to the bottom of the feed box 4. The motor 5 drives the transmission rod 17 to rotate, and multiple agitator paddles 22 on the outer periphery of the transmission rod 17 powerfully agitate the material. Simultaneously, the ingenious structural design of the telescopic rod 18, spring 19, connecting rod 20, and scraper 21 ensures that the telescopic rod 18, under centrifugal force, keeps the scraper 21 in close contact with the inner wall of the mixing tank 2 throughout the agitation process. As the agitator paddles 22 rotate, the scraper 21 continuously scrapes the tank wall, effectively preventing material from sticking to the wall. This avoids waste and spoilage caused by material residue and ensures thorough and uniform mixing of the material within the mixing tank 2, improving the stability of product quality.

[0029] refer to Figure 1 In this embodiment, a support plate 1 is fixedly connected to the outer periphery of the mixing tank 2, a valve 11 is fixedly connected to the bottom of the mixing tank 2, a plurality of evenly distributed support feet 13 are fixedly connected to the bottom of the support plate 1, a buffer pad 12 is fixedly connected to the bottom of the support feet 13, an operation panel 9 is detachably installed on one side of the support plate 1, two evenly distributed screws 10 are threadedly connected to the outer periphery of the operation panel 9, a viewing window 8 is fixedly connected to the outer surface of the mixing tank 2, a sieve plate 15 penetrates one side wall of the feed box 4, and a pull plate 7 is fixedly connected to one end of the sieve plate 15.

[0030] Specifically, valve 11 controls the discharge of rice after mixing, and the buffer pad 12 at the bottom of the support foot 13 buffers the vibration of the machine as a whole during the mixing process. The control panel 9 is detachably mounted on one side of the support plate 1 via screws 10, facilitating installation, disassembly, and maintenance by the operator. The operator can intuitively control the operation of motor 5 and motor 14 through the control panel 9, and precisely adjust parameters such as mixing speed and sieving frequency. The pull plate 7 facilitates the replacement of the sieve plate 15.

[0031] The working principle and usage process of this utility model are as follows: During operation, rice and other materials enter the feeding box 4 through the feed inlet 6. First, in the screening and cleaning assembly, the material falls onto the screen plate 15. Smaller particles fall below through the screen plate 15, while larger impurities are trapped by the screen plate 15. At this time, the second motor 14 is started, which drives the reciprocating screw 24 to rotate. Since the scraper 23 is threadedly connected to the reciprocating screw 24 and slides on the steel pipe 25, the scraper 23 will move back and forth on the screen plate 15, clearing the blockages on the screen plate 15 and ensuring the smooth progress of the screening process. The screened material enters the mixing tank 2 through the guide plate 16. Next, the first motor 5 is started, which drives the transmission rod 17 to rotate. The stirring paddle 22 on the outer periphery of the transmission rod 17 rotates accordingly, stirring and mixing the material. During the mixing process, the structure consisting of the telescopic rod 18, spring 19, connecting rod 20, and scraper 21 ensures that scraper 21 remains in close contact with the inner wall of the mixing tank 2 under the action of spring 19. As the mixing paddle 22 rotates, scraper 21 continuously scrapes the tank wall, preventing material from sticking and ensuring thorough and uniform mixing. Operators can control the start / stop and speed of motors 5 and 14 via the control panel 9, and simultaneously observe the mixing process through the viewing window 8 to adjust mixing parameters. After mixing is complete, valve 11 at the bottom of the mixing tank 2 is opened for material discharge. The slag discharge ports 3 on both sides of the feed box 4 can periodically clean impurities remaining from the screening process. The entire device has a reasonable structure, with all components working collaboratively to effectively achieve functions such as mixing, screening, cleaning, and impurity discharge in rice processing.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
