[0026] Referring to Figures 1-7 , a mechanism sand crushing device includes a pretreatment section 6 rotatably mounted on a crushing section 7 through a rotating part 11; a drying section 4 mounted on a bottom plate 1; a fan 3 mounted on the bottom plate 1, and the drying section 4 is communicated with the fan 3; a connecting pipe 5, any end of the connecting pipe 5 is communicated with the fan 3, and the other end of the connecting pipe 5 is communicated with the pretreatment section 6 through a rotating head.

[0027] The pretreatment section 6 is used for preprocessing the material before it enters the crushing section 7, removing over-wet materials, and realizing the uniform distribution of the material through the rotating part 11, ensuring that the material evenly enters the crushing section 7 and avoiding blockage caused by uneven feeding.

[0028] The drying section 4 dries the material by heating, reduces the water content of the material, reduces the adhesion between materials, avoids forming lumps, improves the crushing efficiency, reduces the possibility of blockage. Under the combined action of the drying section 4, the fan 3, the connecting pipe 5 and the pretreatment section 6, the lumps in the material are effectively treated, the possibility of blockage is reduced, the maintenance cost is reduced, the overall operation of the production line is made smoother, and the production efficiency is improved.

[0031] Multiple stirring rods 803 are used to stir and mix the materials. The rotation of the driving member 801 drives the connecting member 802 and the stirring rods 803 to rotate together. During the rotation process, the stirring rods 803 stir the materials to make them mix evenly, reduce the formation of lumps, make the materials more uniform before entering the crushing section 7, reduce the formation of lumps, and improve the efficiency of subsequent crushing.

[0032] The converging hopper 14 is installed below the pretreatment section 6; the discharge pipe 15 is installed below the converging hopper 14, and an electric valve is provided on the discharge pipe 15.

[0033] The converging hopper 14 collects the materials falling from the pretreatment section 6, ensures that the materials can be evenly collected and guided to the discharge pipe 15, and reduces the risk of blockage.

[0037] The second elastic member 13 is used to support the other side of the filter frame 10, and also plays an elastic supporting role. The second elastic member 13 is a spring, etc.

[0038] The filter frame 10 screens the crushed materials, removes the materials that do not meet the particle size requirements. The first elastic member 12 and the second elastic member 13 make the filter frame 10 have a certain vibration, which helps the materials to pass through the sieve holes, and also facilitates the cleaning of the sieve holes, ensuring that only the materials that meet the particle size requirements can pass through the sieve holes, and the materials that do not meet the requirements will be blocked, thus ensuring the quality of the finished product. The inclined filter frame 10 helps the flow of the materials, reduces the accumulation of the materials at the sieve holes, and reduces the risk of blockage.

[0040] The mounting member 16 is used to fix the position of the cleaning brush 18, ensuring that the cleaning brush 18 is correctly installed on the discharge pipe 15 and in contact with the filter frame 10.

[0041] The cleaning brush 18 is installed on the mounting member 16, in contact with the filter frame 10, made of an elastic material. By contacting the surface of the filter frame 10, it removes the residual materials attached to the filter frame 10. Through continuous cleaning, it can reduce the accumulation of materials on the sieve holes, lower the risk of sieve hole blockage, ensure that the sieve holes of the filter frame 10 always remain unobstructed, and improve the screening efficiency.

[0042] The vibration motor 17, through the vibration of the vibration motor 17, helps the materials pass through the sieve holes, and also contributes to the cleaning effect of the cleaning brush 18. The vibration helps the materials pass through the sieve holes faster, improving the screening efficiency. The vibration helps remove the residual materials on the sieve holes, reducing the blockage risk.

[0043] The feed hopper 9 is installed on the pretreatment section 6, and the pretreatment section 6 is provided with air inlet holes for cooperating with the connecting pipe 5.

[0044] The feed hopper 9, as the inlet for materials to enter the pretreatment section 6, guides the materials to evenly enter the interior of the pretreatment section 6, ensuring that the materials can smoothly enter the pretreatment section 6, providing a stable material source for the subsequent pretreatment process.

[0045] The pretreatment section 6 is provided with air inlet holes for cooperating with the connecting pipe 5, which are connected to the connecting pipe 5 and allow the air flow from the fan 3 to enter the pretreatment section 6, which can help dry the materials and reduce the adhesion between the materials.

[0046] The crushing section 7 is provided with a sealing door, and the sealing door is provided with an observation window and a handle; the controller 2 is installed on the bottom plate 1.

The working status, parameter settings, etc. of the crusher are displayed through the display screen, and the operation control of each component of the crusher is realized through the control buttons.

[0048] During use, materials enter the pretreatment section 6 through the feed hopper 9. The fan 3 sucks the hot air in the drying section 4 into the pretreatment section 6 through the connecting pipe 5, thereby drying the materials in the pretreatment section 6. The driving member 801 drives the connecting member 802 to rotate, and the connecting member 802 drives the stirring rod 803 to rotate, thereby stirring the materials. The rotating section 11 drives the pretreatment section 6 to rotate, making the drying effect better. After drying, the materials fall on the filter frame 10 through the converging hopper 14 and the discharge pipe 15. The vibration motor 17 drives the filter frame 10 to vibrate, so that most of the materials are discharged from the openings on the filter frame 10 and the crushing section 7, and a smaller part is processed by the crushing section 7. When the pretreatment section 6 rotates through the rotating section 11, it drives the converging hopper 14 and the discharge pipe 15 to rotate, thereby driving the mounting member 16 and the cleaning brush 18 to rotate. The cleaning brush 18 cleans the filter frame 10 to reduce blockage.
