[0002] In the process of mortar production, the pretreatment link of materials directly affects the quality, production efficiency and cost of mortar. Traditional material pretreatment methods mostly adopt natural drying, manual crushing and screening, etc. These methods are not only inefficient, but also difficult to meet the needs of large-scale and continuous production. For example, natural drying is greatly affected by weather conditions and has a long treatment cycle; manual crushing and screening have a high labor intensity and unstable treatment effects. With the development of technology, automatic pretreatment mechanisms have emerged, but there are certain defects in the use of existing pretreatment mechanisms.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 - 3 shown, a material pretreatment mechanism includes a housing part. Inside the housing part, a crushing roller 8 is rotatably connected. A crushing channel for crushing materials is formed between the peripheral surface of the crushing roller 8 and the inner wall of the housing part. A sieve plate 13 for screening the crushed materials is provided inside the housing part. Sieve holes 11 are formed in the sieve plate 13. A dust collection part is installed outside the housing part. The intake end of the dust collection part extends into the housing part, and the intake end of the dust collection part is above the sieve plate 13. The outlet end of the dust collection part is connected with a detachable dust collection bag 18. A discharge hole for discharging the crushed materials is formed at the bottom of the housing part.

[0022] Through the above technical solution, when personnel need to pretreat materials, the materials to be processed are added into the housing part. After the materials are added, the crushing roller 8 rotates inside the housing to break the materials. After the materials are broken, they are discharged from the bottom of the crushing roller 8. The processed materials are screened by the sieve plate 13, so that the materials that do not meet the requirements remain on the sieve plate 13, and the materials that meet the requirements pass through the sieve holes 11 on the sieve plate 13 and fall to the lower part and are discharged through the discharge hole. When performing material pretreatment, the dust collection part works to suck the dust and discharge the dust into the dust collection bag 18 for collection, thereby completing the material pretreatment and avoiding the pollution of the surrounding environment caused by the scattering of dust.

[0023] To improve the material processing efficiency, asFigures 1 - 3 As shown, the material pretreatment mechanism further includes a pretreatment part, and the pretreatment part includes a first housing 2. A first motor 3 is fixedly connected inside the first housing 2, and the output end of the first motor 3 is connected to a first stirring rod 4. The first stirring rod 4 is inside the first housing 2, and a communication pipe 14 is provided between the first housing 2 and the housing part.

[0024] Through the above technical solution, when personnel need to process materials, the materials to be processed are added into the first housing 2. When adding materials, the first motor 3 works, and then the first motor 3 drives the first stirring rod 4 to rotate inside the first housing 2, so as to mix the materials. After the materials are fully mixed, they are transported to the inside of the housing part through the communication pipe 14, making the material processing more efficient.

[0025] In addition, in the present utility model, regarding the above dust collection part, as Figures 1 - 3 shown, the dust collection part includes a vacuum pump 7. The intake end of the vacuum pump 7 is connected to an intake pipe 16, and the outlet end is connected to an outlet pipe 17. The free end of the intake pipe 16 extends to the inside of the housing part, and a filter screen 15 is fixedly connected to the end of the intake pipe 16 extending into the housing part. The outlet end of the outlet pipe 17 is fixedly connected to a dust collection bag 18.

[0026] Through the above technical solution, when the materials are crushed and pretreated, the vacuum pump 7 works, so that the intake pipe 16 on the vacuum pump 7 generates suction, and the dust is sucked through the intake pipe 16. When the intake pipe 16 sucks in the dust, the filter screen 15 blocks the entry of materials, so that the dust can pass through the filter screen 15 and is discharged to the dust collection bag 18 through the outlet pipe 17 on the vacuum pump 7 for collection, thus completing the material pretreatment.

[0027] Specifically, in another embodiment, regarding the above housing part:

[0028] As Figures 1 - 3 shown, the housing part includes a crushing bin 6. The communication pipe 14 is arranged between the crushing bin 6 and the first housing 2. The crushing roller 8 is rotatably connected inside the crushing bin 6;

[0029] A second motor 5 is fixedly connected to the top of the crushing bin 6, and a discharge pipe 12 is fixedly connected to the bottom of the crushing bin 6. The discharge pipe 12 is communicated with the inside of the crushing bin 6, and the output end of the second motor 5 is connected to the crushing roller 8.

[0030] Through the above technical solution, when the materials are fully mixed, the materials are transported to the inside of the crushing bin 6 through the communication pipe 14. The second motor 5 drives the crushing roller 8 to rotate inside the crushing bin 6, and the crushing bin 6 and the crushing roller 8 are used to perform crushing pretreatment on the materials.

[0031] To facilitate the cleaning of the residual large-particle raw materials on the sieve plate 13, asFigure 3 As shown, a cleaning port 19 communicating with the inside of the crushing bin 6 is provided on one side of the crushing bin 6. A detachable sealing cover 1 is screwed and connected inside the cleaning port 19. The sieve plate 13 is inclined and arranged inside the crushing bin 6, and the horizontal height of the sieve plate 13 on the side facing the cleaning port 19 is lower than that on the other side.

[0032] Through the above technical solution, after all the pre-crushed materials are discharged from the device, rotate the sealing cover 1 to separate the sealing cover 1 from the cleaning port 19, and the residual raw materials can be discharged through the cleaning port 19.

[0033] When the discharge pipe 12 needs to discharge the processed materials, in order to improve the material discharge efficiency, as Figure 3 shown, a auger 9 is rotatably connected inside the discharge pipe 12, and a third motor 10 is fixedly connected to the outside of the discharge pipe 12. The output end of the third motor 10 is connected to the auger 9.

[0034] Through the above technical solution, after the materials are pre-crushed, the pre-crushed materials pass through the sieve holes 11 and fall to the bottom of the crushing bin 6. The third motor 10 drives the auger 9 to rotate, and the auger 9 drives the materials to move inside the discharge pipe 12, so that the pre-crushed materials can be stably and efficiently discharged through the discharge pipe 12.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
