[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] Example 1, as Figure 1-3 As shown, a gypsum raw material crushing and grinding device for orthopedics includes an outer box body 1, a feed port 11 is provided at the upper end of the outer box body 1, a fixed block 12 is fixedly connected to the rear side of the outer box body 1, a fixed block 2 13 is fixedly connected to the rear side of the outer box body 1, a crushing component 2 is provided inside the outer box body 1 to crush the gypsum raw material, a flip component 3 is provided on the lower side of the crushing component 2, which can swing left and right to evenly distribute the crushed gypsum raw material to the left and right sides, a grinding component 4 is provided on the lower side of the flip component 3, a cleaning component 5 is provided on the lower side of the grinding component 4, which can clean the bottom of the grinding component 4 to prevent blockage, and a collection box 6 is provided on the lower side of the cleaning component 5. The ground powder is stored in the collection box 6 and can be drawn out as a whole to provide materials for orthopedic treatment.

[0018] Therefore, this solution uses the coordination of the crushing component 2 and the flipping component 3 to allow the gypsum raw material to fall from both sides after being crushed and evenly distributed in the grinding trough, thereby improving the particle size uniformity of the ground gypsum powder. In addition, the grinding component 4 and the cleaning component 5 are linked to simultaneously clean the filter while grinding the gypsum raw material, effectively preventing blockage and ensuring the smooth progress of the grinding process, thereby providing high-quality raw materials for orthopedic treatment.

[0019] Example 2: Based on Example 1, this example is to achieve the effect of discharging the crushed gypsum raw materials in batches from different positions.

[0020] See Figure 1-5The crushing assembly 2 includes a motor 21 fixedly installed on the upper end of the fixed block 12, the output end of the motor 21 is fixedly connected to a rotating shaft 22, the end of the rotating shaft 22 away from the motor 21 is fixedly connected to a crushing roller 23, the outer surface of the rotating shaft 22 is fixedly connected to a transmission mechanism 24, the side of the transmission mechanism 24 away from the crushing roller 23 is fixedly connected to a rotating shaft 25, and the end of the rotating shaft 25 away from the transmission mechanism 24 is fixedly connected to a crushing roller 26.

[0021] Specifically, the transmission mechanism 1 24 is composed of a driving wheel, a driven wheel and a belt. The transmission mechanism 1 24 can make the rotating shaft 1 22 and the rotating shaft 2 25 rotate together, and the crushing roller 1 23 and the crushing roller 2 26 can crush the gypsum raw materials passing between the two.

[0022] Furthermore, the starting motor 21 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the crushing roller 23, the transmission mechanism 24 and the rotating shaft 25 to rotate, so that the crushing roller 23 and the crushing roller 2 26 rotate together to crush the gypsum raw material.

[0023] See Figure 4 and Figure 5 The flip assembly 3 includes a transmission mechanism 2 31 fixedly connected to one end of the rotating shaft 25 away from the crushing roller 26, and a gear 32 fixedly connected to one end of the transmitting mechanism 2 31 away from the rotating shaft 25, and the number of the gears 32 is two.

[0024] The front sides of the two gears 32 are fixedly connected to a rotating rod 33, the outer surfaces of the two rotating rods 33 are fixedly connected to a toggle block 34, the outer surfaces of the two toggle blocks 34 are slidably connected to a groove wheel 35, the front side of the groove wheel 35 is fixedly connected to a connecting rod 36, and the outer surface of the connecting rod 36 is fixedly connected to a flip plate 37.

[0025] Furthermore, the transmission mechanism 2 31 mentioned above is composed of a driving wheel, a driven wheel and a belt, which can make the gear 32 follow the rotating shaft 2 25 and rotate together with the transmission mechanism 2 31, and the two gears 32 are in a mutually meshing state, and the rotation directions of the two are opposite. The rotation of the gear 32 can drive the two rotating rods 33 and the toggle block 34 to rotate. The initial positions of the two toggle blocks 34 are different. When the two rotate, they can intermittently toggle the groove wheel 35 back and forth by ninety degrees, so that the connecting rod 36 drives the flip plate 37 to flip left and right, so that the crushed gypsum raw materials are distributed and fall, reducing the risk of raw materials accumulating in the grinding trough, and realizing the uniform distribution of crushed gypsum raw materials.

[0026] Therefore, this solution cooperates with the crushing component 2 and the flipping component 3, so that when the crushing component 2 crushes the gypsum raw material, it can use the structures such as the toggle block 34 and the groove wheel 35 to drive the flip plate 37 to flip left and right, so that the crushed gypsum raw material is distributed and falls, reducing the problem of gypsum raw material accumulation during grinding, grinding the raw material more effectively, ensuring the quality and uniformity of the gypsum powder, providing high-quality raw materials for orthopedic treatment, and improving treatment effects and patient satisfaction.

[0027] Embodiment 3: Based on Embodiments 1 and 2, this embodiment is to achieve the effect of cleaning the filter 411 simultaneously during grinding.

[0028] See Figure 6 and Figure 7 The grinding assembly 4 includes a grinding seat 41 fixedly connected to the inner surface of the outer box body 1, a filter screen 411 is provided at the lower end of the grinding seat 41, a motor 2 42 is fixedly installed on the upper end of the fixed block 2 13, and the output end of the motor 2 42 is fixedly connected to the rotating shaft 3 421, and the rear side wall of the inner surface of the outer box body 1 is fixedly connected to the fixed shell 45, and the inner surface of the fixed shell 45 is rotatably connected to the rotating column 44, and the rotating column 44 and the outer surface of the rotating shaft 3 421 are jointly fixedly connected to the bevel gear transmission group 43.

[0029] Specifically, the filter 411 can intercept unground gypsum fragments to ensure that only powdered gypsum that meets the particle size requirements can pass through. It is made of stainless steel, has good wear resistance and impact resistance, can withstand friction and impact during the grinding process, and is not easily deformed or damaged.

[0030] Furthermore, the bevel gear transmission assembly 43 is composed of two bevel gears meshing with each other, which can change the direction of rotation and cause the rotating column 44 to start rotating.

[0031] See Figure 6 The lower end of the rotating column 44 is fixedly connected to a rotating disk 46, and one side of the lower end of the rotating disk 46 is fixedly connected to a grinding block 47. The lower end of the grinding block 47 is slidingly connected to the grinding seat 41. The outer surface of the rotating column 44 is fixedly connected to a connecting seat 48, and the lower end of the connecting seat 48 is fixedly connected to a cleaning brush 49.

[0032] Furthermore, the grinding block 47 rotates around the axis of the rotating disk 46 when rotating. The fitting position of the grinding block 47 and the inner wall of the grinding seat 41 can fully grind the crushed gypsum raw materials, and the cleaning brush 49 can sweep the gypsum fragments remaining around the grinding seat 41 into the groove to avoid uneven grinding or omissions.

[0033] Starting motor 2 42 drives rotating shaft 3 421 to rotate, and drives rotating column 44 to rotate through bevel gear transmission group 43, thereby driving rotating disk 46, grinding block 47 and connecting seat 48 to rotate together. The grinding block 47 can grind the gypsum fragments, and the connecting seat 48 also continuously slides on the surface of the grinding seat 41 to scrape off the residual fragments around it, avoiding waste of raw materials and reduction of grinding efficiency.

[0034] See Figure 7 The cleaning component 5 includes a transmission mechanism 3 51 fixedly connected to the outer surface of the rotating shaft 3 421, and a bidirectional screw 52 is fixedly connected to the side of the transmission mechanism 3 51 away from the rotating shaft 3 421, and a cleaning brush 2 53 is threadedly connected to the outer surface of the bidirectional screw 52.

[0035] The inner surface of the second cleaning brush 53 is slidably connected to two limiting rods 54 , both ends of the two limiting rods 54 are fixedly connected to the outer box body 1 , and the upper end of the second cleaning brush 53 is slidably connected to the filter screen 411 .

[0036] Furthermore, the transmission mechanism three 51 is composed of a driving wheel, a driven wheel and a belt, which can drive the bidirectional screw 52 to rotate. The rotation of the bidirectional screw 52 can drive the cleaning brush two 53 to move back and forth. The two limit rods 54 can limit the cleaning brush two 53, so that it can move back and forth stably to clean the filter 411, reducing the hospital's maintenance cost and time for the device.

[0037] Furthermore, when the motor 2 42 rotates, it will drive the transmission mechanism 3 51 to rotate, thereby driving the bidirectional screw 52 to rotate, so that the cleaning brush 2 53 moves back and forth on the surface of the filter 411, cleaning the surface of the filter 411, effectively preventing the filter 411 from being blocked, ensuring the smooth progress of the grinding process, reducing the overall maintenance cost and time, and the ground powder is stored in the aggregate box 6 and can be drawn out as a whole.

[0038] Therefore, this solution cooperates with the grinding component 4 and the cleaning component 5 so that when the grinding block 47 is grinding the gypsum fragments, the cleaning brush 2 53 can continuously clean the filter 411 at the grinding site, effectively preventing the filter from being blocked, ensuring the smooth progress of the grinding process, reducing the overall maintenance cost and time, and reducing the operating costs of medical institutions.

[0039] It should be noted that the specific installation method, circuit connection method and control method of the motor 1 21 and the motor 2 42 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
