Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1

[0027] Please see Figure 1-5This utility model provides a technical solution: a mixer with screening function, including a fixed frame 1, a mixer 2 and a mounting frame 3 fixedly mounted on the surface of the fixed frame 1, a protective cover 4 and a shock-absorbing spring 5 fixedly mounted on the surface of the mounting frame 3, a grinding wall 6 fixedly mounted inside the protective cover 4, a crushing roller 7 rotatably connected inside the protective cover 4, a coupling 8 fixedly mounted at one end of the crushing roller 7, a screening box 9 fixedly mounted on the surface of the shock-absorbing spring 5, a screen plate 10 slidably connected inside the screening box 9, a discharge port 11 opened on the surface of the screening box 9, a feeding box 12 placed below the discharge port 11, a discharge guide 13 fixedly mounted at the bottom of the screening box 9, a vibrating motor 14 fixedly mounted on the surface of the discharge guide 13, a motor 15 and a fixed plate 16 fixedly mounted on the surface of the mounting frame 3, a transmission belt 17 rotatably connected to the output end of the motor 15, an auger feeder 18 fixedly mounted on the surface of the fixed plate 16, and a coupling 8 connected to the transmission belt 17. The belts 17 are rotatably connected. The operation of the motor 15 drives the coupling 8 to rotate, causing the crushing roller 7 to rotate at high speed, achieving initial crushing of the material. Through the interaction between the grinding wall 6 and the crushing roller 7, the material is further refined. The screen plate 10 is made of polyurethane, which has good elasticity and wear resistance, effectively absorbing the impact energy of the material and reducing the wear of the screen plate 10. In addition, it has high screening efficiency, is not easy to clog, and can improve noise, thus improving the comfort of the working environment. The conveying port of the auger feeder 18 is located inside the feeding box 12, and the discharge port is located inside the protective cover 4. After being screened by the screen plate 10, some larger raw material particles are discharged into the feeding box 12 through the discharge port 11. Then, the auger feeder 18 transports these larger raw material particles into the protective cover 4 for further crushing until the required fineness is achieved, ensuring that the concrete raw materials are uniform and fine, and improving the mixing efficiency and quality.

[0028] Example 2

[0029] Please see Figure 6-8The screening box 9 has a first mounting box 19 and a second mounting box 20 fixedly mounted on its surface. A retaining plate 21 is slidably connected inside the first mounting box 19. A return spring 22 is fixedly mounted on the surface of the retaining plate 21, and a fixing groove 23 is fixedly mounted on its surface. A fixing block 24 is slidably connected inside the second mounting box 20. A limit rod 25 and a spring 26 are fixedly mounted on the surface of the fixing block 24. A handle 27 is fixedly mounted on one end of the limit rod 25. By pulling the handle 27, the fixing block 24 is moved out of the fixing groove 23. The retaining plate 21 will spring back into the first mounting box 19 under the action of the return spring 22, thus releasing the fixation on the screening plate 10. The screen plate 10 is fixedly installed between the return spring 22 and the first mounting box 19, and the clamping plate 21 is slidably connected between the screen plate 10 and the second mounting box 20 to ensure the stability of the screen plate 10 during the screening process. The spring 26 is fixedly installed between the spring 26 and the second mounting box 20, and the second mounting box 20 is slidably connected between the limit rod 25 and the fixing block 24 is slidably connected between the fixing groove 23. Pulling the handle 27 causes the fixing block 24 to move smoothly out of the fixing groove 23 through the limit rod 25. The return spring 22 pulls the clamping plate 21 back to its original position, realizing the rapid release and fixation of the screen plate 10.

[0030] Working principle: First, the raw material is poured into the feeding box 12 and conveyed to the protective cover 4 by the auger feeder 18. Driven by the motor 15, the transmission belt 17 drives the crushing roller 7 to rotate. The raw material is crushed under the impact of the rotating crushing roller 7. The crushed material is then impacted onto the grinding wall 6 for secondary crushing. The refined raw material is then efficiently screened through the screen plate 10 by the vibrating motor 14. Fine particles enter the mixer 2 through the discharge pipe 13 for mixing, while larger particles return to the feeding box 12 through the discharge port 11 and are again conveyed to the protective cover 4 by the auger feeder 18 for secondary crushing until the required fineness is achieved, ensuring the raw material is uniform and fine. When it is necessary to remove the screen plate 10 for replacement or cleaning, it can be... Pulling handle 27 causes the fixing block 24 to slide out of the fixing groove 23. At this time, the retaining plate 21 will retract into the first mounting box 19 under the elastic force of the return spring 22, thus canceling the fixing effect on the screen plate 10. When it is necessary to fix the screen plate 10, simply insert the screen plate 10 into the screening box 9, and then push the retaining plate 21 into the second mounting box 20. When the front end of the retaining plate 21 contacts the inclined surface of the fixing block 24, the retaining plate 21 will push the fixing block 24 into the second mounting box 20. When the fixing groove 23 on the retaining plate 21 contacts the fixing block 24, the fixing block 24 will be smoothly inserted into the fixing groove 23 under the elastic force of the spring 26 and the positioning effect of the limiting rod 25, thereby achieving the fixing of the retaining plate 21 and the screen plate 10.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
