A C-shaped tube 905 is fixedly installed at one end of the 2, and a housing 906 is fixedly installed at both ends of the C-shaped tube 905. A sliding groove 907 is opened on one side of the housing 906, and a filter collection frame 908 is slidably connected inside the sliding groove 907. A side plate 909 is fixedly installed on the side of the filter collection frame 908 away from the sliding groove 907. A handle 910 is fixedly installed on the side of the side plate 909 away from the filter collection frame 908. A limit groove 911 is opened on one side of the side plate 909. A sealing gasket 912 is fixedly installed on the side of the side plate 909 close to the filter collection frame 908. There are two sets of shafts 5, crushing rollers 6 and gears 7. The two sets of gears 7 mesh with each other. The output end of the drive motor 8 is fixedly connected to one of the sets of shafts 5. There are two sets of housings 906. The two sets of housings 906 are fixedly connected to the box 1. The fixing plate 901 is fixedly connected to the box 1.

[0024] In the embodiment, the dust suction mechanism 9 is used to achieve efficient dust prevention. When the air suction pump 902 is working, negative pressure is formed at the shell 906 through the pipeline I 903 and the C-shaped pipe 905, so that the dust generated during the crushing process can be sucked into the shell 906 in time. After the dust is filtered by the filter collection frame 908, the particulate impurities are intercepted, and the clean air is discharged. Thus, the dust is effectively prevented from spreading to the working environment, the health of the operator is ensured, and the environmental protection production requirement is met. Meanwhile, the sealing gasket 912 on the side plate 909 enhances the sealing performance of the filter collection frame 908 and the shell 906, further prevents the dust from overflowing from the gap, and improves the dust prevention effect.

[0025] Embodiment 2: as shown in Figure 1 and Figures 4-5 The quick release mechanism 10 includes a guide rod 101, one end of the guide rod 101 is fixedly installed with a fixed block 102, the outer wall of the guide rod 101 is slidably connected with a sliding plate 103, the side of the sliding plate 103 away from the fixed block 102 is symmetrically fixedly installed with a limiting insert plate 104, the outer wall of the guide rod 101 is sleeved with a spring 105, one end of the spring 105 is fixedly connected with the sliding plate 103, the other end of the spring 105 is fixedly connected with the fixed block 102, the number of the guide rods 101 is two groups, the two groups of guide rods 101 are fixedly connected with the box body 1, and the limiting insert plate 104 is slidably connected with the limiting groove 911.

[0026] In the embodiment, the quick release mechanism 10 provides convenient operation for cleaning the filter collection frame 908. When the dust in the filter collection frame 908 needs to be cleaned, the sliding plate 103 is pushed towards the fixed block 102, the sliding plate 103 slides along the guide rod 101 and compresses the spring 105, the limiting insert plate 104 is driven to disengage from the limiting groove 911 of the side plate 909. At this time, the filter collection frame 908 can be pulled out from the shell 906 along the sliding groove 907 for cleaning by holding the handle 910. After cleaning, the filter collection frame 908 is inserted into the sliding groove 907 again, the sliding plate 103 is released, the spring 105 is reset to push the sliding plate 103 to drive the limiting insert plate 104 to be inserted into the limiting groove 911, and the fixing of the filter collection frame 908 is completed. This process does not need to disassemble additional connecting parts, and the maintenance efficiency is greatly improved.

[0027] The working principle of the embodiment is as follows: when the building material is crushed, the driving motor 8 is started, and a group of shaft rods 5 are driven to rotate by the output end of the driving motor 8. Since the gears 7 at one end of the two groups of shaft rods 5 are engaged with each other, the other group of shaft rods 5 is driven to rotate in the opposite direction synchronously, so that the two groups of crushing rollers 6 rotate oppositely in the box body 1. After the crushing rollers 6 rotate, the building material to be crushed is thrown into the box body 1 from the feeding hopper 3, and is crushed into particles meeting the specifications under the extrusion and shearing action of the two groups of crushing rollers 6. The crushed particles are discharged through the discharge hopper 4 at the bottom of the box body 1, and the basic crushing process is completed. During the crushing process, the air suction pump 902 can be started. After being started, negative pressure is formed through the pipeline one 903 and the C-shaped pipe 905. The dust generated in the crushing process in the box body 1 is sucked into the two groups of housings 906. When the dust passes through the filter collection frame 908 installed in the housing 906, the impurities in the dust are filtered and retained, and the clean air is discharged in sequence through the C-shaped pipe 905, the pipeline one 903, the air suction pump 902, and the pipeline two 904. The filter collection frame 908 is slidably connected to the housing 906 through the sliding groove 907. The sealing gasket 912 on one side of the side plate 909 can enhance the sealing between the housing 906 and the sealing gasket 912, so as to avoid the overflow of dust from the gap and ensure the dust collection effect. The quick release mechanism 10 provides convenient operation for cleaning the filter collection frame 908. When it is necessary to clean the dust in the filter collection frame 908, the sliding plate 103 is pushed towards the fixed block 102. The sliding plate 103 slides along the guide rod 101 and compresses the spring 105, so that the limiting insert plate 104 is separated from the limiting slot 911 of the side plate 909. At this time, the filter collection frame 908 can be pulled out of the housing 906 along the sliding groove 907 for cleaning by holding the handle 910. After cleaning, the filter collection frame 908 is inserted into the sliding groove 907 again, the sliding plate 103 is released, the spring 105 is reset, the sliding plate 103 is driven, the limiting insert plate 104 is inserted into the limiting slot 911, and the fixing of the filter collection frame 908 is completed. This process does not need to disassemble additional connecting parts, and the maintenance efficiency is greatly improved.

[0028] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application still falls within the protection scope of the technical scheme of the present application.
