[0004] In the above-mentioned utility model patent, the rice that has been ground by the grinding roller falls onto the filter plate during the use of the crushing device. Particles with a particle size smaller than the mesh size of the filter plate pass through the filter plate and fall onto the guide plate, while particles with a particle size larger than the mesh size of the filter plate will remain on the filter plate or even get stuck in the mesh, causing the filter plate to be blocked and affecting the working efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a rice enzymatic protein grinding device, which solves the problem of filter plate clogging affecting work efficiency in existing grinding devices.

[0006] According to an embodiment of this utility model, a rice enzymatic protein grinding device includes a frame and a main body mounted on the frame. The main body has a processing chamber and a filter plate is provided inside the processing chamber. The filter plate divides the processing chamber into a first chamber and a second chamber. The main body is provided with an inlet communicating with the first chamber and a outlet communicating with the second chamber. A rotatable main shaft is also provided inside the processing chamber, and a drive component connected to the main shaft is provided on the main body. The main shaft passes through the first chamber and the filter plate in sequence and extends into the second chamber. A first cutter is provided on the portion of the main shaft located inside the first chamber, and a first grinding disc is provided on the portion of the main shaft located inside the second chamber. A second grinding disc is provided around the first grinding disc in the second chamber. There is a gap between the first grinding disc and the second grinding disc communicating with the outlet. The width of the gap gradually decreases along the direction close to the outlet. A rotating frame is also provided on the portion of the main shaft located inside the first chamber. A brush is provided on the rotating frame and the brush abuts against the filter plate.

[0007] Furthermore, the main body is provided with a plurality of driven shafts spaced circumferentially along the main shaft. The driven shafts are respectively connected to the main shaft for transmission. The driven shafts extend into the first chamber and are provided with a second cutter on the portion of the driven shaft located in the first chamber. The second cutter and the first cutter are arranged alternately.

[0008] Furthermore, the main shaft is provided with a driving gear, and the driven shaft is provided with driven gears, and the driven gears mesh with the driving gears respectively.

[0009] Furthermore, the angle between the first cutter and the horizontal plane is an acute angle, and the angle between the second cutter and the horizontal plane is an acute angle and is not equal to the angle between the first cutter and the horizontal plane.

[0010] Furthermore, the driving component includes a first motor, the main shaft is coupled to the output end of the first motor, and the frame is provided with a mounting bracket for mounting the first motor.

[0011] Furthermore, the main body is also provided with a material conveying channel connecting the end of the first chamber near the filter plate and the end of the first chamber away from the filter plate, and a spiral conveying assembly is provided in the material conveying channel.

[0012] Furthermore, the spiral conveying assembly includes a second motor and a conveying shaft disposed at the output end of the second motor. The conveying shaft is rotatably disposed on the main body and extends into the conveying channel, and the portion of the conveying shaft located within the conveying channel is provided with spiral blades.

[0013] Furthermore, the rotating frame is also provided with a scraper, which is located on the side of the rotating frame away from the main shaft and extends towards the bottom surface of the first chamber.

[0015] Furthermore, the main body is also equipped with a solenoid valve, which is located at the opening of the discharge port.

[0016] Compared with existing technologies, this utility model has the following advantages: By employing a main body with a processing chamber to accommodate the rice to be processed, the rice is poured into the first chamber from the inlet and blocked and retained in the first chamber by the filter plate. When the main shaft rotates under the drive of the drive unit, the first cutter acts on the rice in the first chamber, breaking the rice. After being broken into particles with a particle size smaller than the mesh diameter of the filter plate, the rice can pass through the filter plate and enter the second chamber. At this time, the particles fall into the gap between the first and second grinding discs, and the first grinding disc rotates relative to the second grinding disc under the drive of the main shaft to grind the particles in the gap until the large particles are ground down. Rice grains are ground into powder. The rice powder can pass through the gap between the first and second grinding discs and be discharged from the discharge port, thus processing the rice into powder. During the rotation of the main shaft, the rotating frame rotates synchronously. The brushes set on the rotating frame can clean the filter plate when the rotating frame rotates. The centrifugal force generated by the rotation of the brushes can cause particles stuck on the filter plate that cannot pass through the filter plate to leave the filter plate, thus keeping the filter plate unobstructed. This solves the technical problem of filter plate clogging affecting work efficiency in existing crushing devices, and produces the technical effect of preventing filter plate clogging and ensuring high-efficiency processing of the equipment.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a rice enzymatic protein grinding device, which is used to crush rice into granules and then grind it into powder to facilitate subsequent processing into rice enzymatic protein powder.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3The rice enzymatic protein grinding device includes a frame 1 and a main body 2 mounted on the frame 1. The main body 2 has a processing chamber 21 for accommodating rice to be processed, and a filter plate 3 is provided inside the processing chamber 21. The filter plate 3 divides the processing chamber 21 into a first chamber 22 and a second chamber 23. The main body 2 has an inlet communicating with the first chamber 22 and a outlet communicating with the second chamber 23. Rice can be poured into the processing chamber 21 from the inlet, and the rice is processed into powder and discharged from the outlet. A rotatable main shaft 4 is also provided inside the processing chamber 21, and a drive component is provided on the main body 2 for transmission connection with the main shaft 4. The main shaft 4 passes through the first chamber 22 and the filter plate 3 in sequence and extends into the second chamber 23. A first cutter 41 is provided on the portion of the main shaft 4 located in the first chamber 22. The cutter is used to break the rice in the first chamber 22 into granules that can pass through the filter plate 3. A first grinding disc 42 is provided on the portion of the shaft 4 located within the second chamber 23, and a second grinding disc 24 is provided around the first grinding disc 42 within the second chamber 23. A gap 25 communicating with the discharge port is provided between the first grinding disc 42 and the second grinding disc 24. The width of the gap 25 gradually decreases in the direction close to the discharge port. Rice particles enter the gap 25 after passing through the filter plate 3. When the first grinding disc 42 rotates relative to the second grinding disc 24 as the main shaft 4 rotates, it can grind the rice particles in the gap 25 into powder to process the rice into the required particle size. A rotating frame 43 is also provided on the portion of the main shaft 4 located within the first chamber 22. A brush 44 is provided on the rotating frame 43, and the brush 44 abuts against the filter plate 3. The brush 44 is used to clean the filter plate 3 to prevent rice particles that cannot pass through the filter plate 3 from remaining on the filter plate 3 and causing the filter plate 3 to become clogged.

[0025] In detail, the operation steps of processing rice using the rice enzymatic protein grinding device provided in this embodiment are as follows: The rice to be processed is poured into the first chamber 22 through the feed port. After entering the first chamber 22, the rice is blocked by the filter plate 3 and remains in the first chamber 22. The drive unit is activated to drive the main shaft 4 to rotate. The first cutter 41 acts on the rice as the main shaft 4 rotates, breaking the rice. After the rice is broken into particles with a particle size smaller than the mesh diameter of the filter plate 3, it can pass through the filter plate 3 and enter the second chamber 23. At this time, the particles fall into the gap 25 between the first grinding disc 42 and the second grinding disc 24. The first grinding disc 42 rotates relative to the second grinding disc 24 under the drive of the main shaft 4 to grind the particles in the gap 25 until the rice particles are ground into powder that can pass through the gap 25 and the rice powder is discharged from the discharge port, thus processing the rice into powder. In the operation of the rice enzymatic protein grinding device provided in this embodiment, the rotating frame 43 rotates synchronously with the rotation of the main shaft 4. The rotating frame 43 rotates the brush 44 to clean the filter plate 3. The centrifugal force generated when the brush 44 rotates can cause particles that are stuck on the filter plate 3 and cannot pass through the filter plate 3 to leave the filter plate 3, thereby keeping the filter plate 3 unobstructed and preventing the filter plate 3 from becoming blocked, ensuring that the equipment can perform rice processing operations with high efficiency.

[0026] like Figure 1 and Figure 2 As shown, the main body 2 is provided with a plurality of driven shafts 5 spaced circumferentially along the main shaft 4. Each driven shaft 5 is connected to the main shaft 4 in a driving manner. A second cutter 51 is provided on the portion of each driven shaft 5 that extends into the first chamber 22 and is located within the first chamber 22. The second cutter 51 is staggered with the first cutter 41. The main body 2 has a plurality of driven shafts 5 respectively connected to the main shaft 4 in a driving manner. When the main shaft 4 rotates under the drive of the driving member, the driven shafts 5 rotate simultaneously. Each driven shaft 5 is provided with a second cutter 51 staggered with the first cutter 41. As the driven shaft 5 rotates, the second cutter 51 acts on the rice in the first chamber 22 and breaks the rice, thus accelerating the rice breaking speed and improving the working efficiency of the rice enzymatic protein grinding device.

[0027] Specifically, the main shaft 4 is equipped with a driving gear 45, and the driven shaft 5 is equipped with driven gears 52, which mesh with the driving gear 45. The main shaft 4 and the driven shaft 5 are connected by transmission through the engagement of the driving gear 45 and the driven gear 52. When the main shaft 4 rotates under the drive of the driving member, the power output by the driving member can be transmitted to the driven shaft 5 through the driving gear 45 and the driven gear 52, ensuring that the driven shaft 5 rotates synchronously with the driving shaft, thereby enabling the first cutter 41 and the second cutter 51 to perform rice crushing operations synchronously.

[0028] In this embodiment, the angle between the first cutter 41 and the horizontal plane is an acute angle, and the angle between the second cutter 51 and the horizontal plane is also an acute angle, but not equal to the angle between the first cutter 41 and the horizontal plane. The first cutter 41 and the second cutter 51 are respectively set to be inclined relative to the horizontal plane, so that the first cutter 41 and the second cutter 51 can fully contact the rice during rotation. Furthermore, setting the inclination angles of the first cutter 41 and the second cutter 51 to be different facilitates the rapid breaking of the rice into small particles.

[0029] like Figure 2 As shown, the driving component includes a first motor 26, and the main shaft 4 cooperates with the output end of the first motor 26. The frame 1 is provided with a mounting bracket 27 for mounting the first motor 26. In this embodiment, the first motor 26 drives the main shaft 4 to rotate, and the cooperation between the main shaft 4 and the output end of the first motor 26 ensures that the power output by the first motor 26 can drive the main shaft 4 to move smoothly. The mounting bracket 27 is also provided on the main body 2 for mounting the first motor 26 to ensure that the position of the first motor 26 on the main body 2 remains stable.

[0030] Please combine Figure 1 and Figure 2The main body 2 is also provided with a conveying channel 28 connecting the end of the first chamber 22 near the filter plate 3 and the end of the first chamber 22 away from the filter plate 3. A spiral conveying assembly 6 is provided in the conveying channel 28. During the process of the brush 44 cleaning particles that cannot pass through the filter plate 3, some particles are pushed into the conveying channel 28 by the brush 44. At this time, the particles entering the conveying channel are conveyed by the spiral conveying assembly 6 from the end of the first chamber 22 near the filter plate 3 to the end of the first chamber 22 away from the filter plate 3 and fall in the first chamber 22. During the fall, the particles can come into contact with the first cutter 41 and the second cutter 51 again and crush the particles until the particles can pass through the filter plate 3, thereby further improving the crushing effect of the rice enzymatic protein grinding device and avoiding the accumulation of particles with excessively large particle sizes in the first chamber 22.

[0031] Specifically, the spiral conveying assembly 6 includes a second motor 61 and a conveying shaft 62 disposed at the output end of the second motor 61. The conveying shaft 62 is rotatably mounted on the main body 2 and extends into the conveying channel, and spiral blades 63 are provided on the portion of the conveying shaft 62 located within the conveying channel. When the conveying shaft 62 rotates under the drive of the second motor 61, the spiral blades 63 move synchronously with the rotation of the conveying shaft 62 and transport the particles in the conveying channel 28, thereby conveying the particles from the end of the first chamber 22 near the filter plate 3 to the end of the first chamber 22 away from the filter plate 3 and feeding them back into the first chamber 22. This achieves cyclical movement of the particles within the first chamber 22, ensuring that the rice entering the first chamber 22 can be effectively broken down.

[0032] like Figure 2 and Figure 4 As shown, the rotating frame 43 is also equipped with a scraper 46. The scraper 46 is located on the side of the rotating frame 43 away from the main shaft 4 and extends towards the bottom surface of the first chamber 22. The scraper 46 can rotate synchronously with the movement of the rotating frame 43 and push the particles at the bottom of the first chamber 22 into the conveying channel 28, avoiding particle retention in the first chamber 22 and causing material loss.

[0033] like Figure 1 As shown, the main body 2 is also provided with a feed hopper 7, which is connected to the feed inlet. The feed hopper 7 is used to guide rice into the first chamber 22, so that the rice to be processed can be added to the rice enzymatic protein grinding device for processing.

[0034] In detail, the main body 2 is also equipped with a solenoid valve 8, which is located at the opening of the discharge port. The solenoid valve 8 is used to control the opening or closing of the discharge port, so as to control the discharge of the rice enzymatic protein grinding device and ensure that the processed powder is collected into a designated container during the discharge of the rice enzymatic protein grinding device.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
