[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 to Figure 3 As shown, this embodiment proposes a construction waste recycling device, including a crushing box 1 and a feeding frame 2 fixedly connected to the top thereof, two exhaust pipes 3 are fixedly connected on the outer wall of the feeding frame 2, and a dust filter box 4 is fixedly connected on the outer wall of the crushing box 1. The bottom ends of the two exhaust pipes 3 are fixedly connected to the two opposite outer walls of the dust filter box 4, respectively, and a filter screen plate 41 and a sealing plate 42 are slidably connected to the outer wall of the dust filter box 4. The connection points between the exhaust pipe 3 and the dust filter box 4 are both located between the filter screen plate 41 and the sealing plate 42. A fan 5 is fixedly connected to the top of the dust filter box 4, and the connection point between the dust filter box 4 and the fan 5 is located on the side of the filter screen plate 41 away from the sealing plate 42. The sealing plate 42 is located at the connection point between the dust filter box 4 and the crushing box 1, and a linkage rod 44 is fixedly connected between the outer walls of the filter screen plate 41 and the sealing plate 42, and one end of the filter screen plate 41 and the sealing plate 42 extend to the outside of the dust filter box 4.

[0026] A mesh cover 31 is provided on one end of the exhaust pipe 3 connected to the feeding frame 2. The mesh cover 31 is fixedly mounted on the inner wall of the feeding frame 2. The mesh cover 31 is provided to intercept solid particles with larger particle sizes when the exhaust pipe 3 extracts the internal air of the feeding frame 2; the two opposite outer walls of the filter screen plate 41 are slidably connected with slide rails 6, and the slide rails 6 are fixedly connected to the inner wall of the dust filter box 4. The slide rails 6 are provided to limit the sliding direction and sliding trajectory of the filter screen plate 41; a handle 43 is fixedly connected to one end of the filter screen plate 41 located outside the dust filter box 4, and the handle 43 is provided for convenient operation when the filter screen plate 41 is pulled out.

[0027] In this embodiment, when the gears are driven by the transmission assembly on the crushing box 1 to crush the concrete, the fan 5 is powered on and started, and the dust-laden air is extracted on the feeding frame 2 through the dust filter box 4 and the exhaust pipe 3. After the exhaust pipe 3 introduces the air between the filter screen 41 and the sealing plate 42, the dust and solid particles are intercepted by the filter mesh on the filter screen 41 and accumulated between the filter screen 41 and the sealing plate 42. The filtered air passing through the filter screen 41 is discharged again through the fan 5, which can prevent a large amount of dust generated during the crushing process from spreading to the surrounding air, thereby avoiding pollution to the surrounding environment.

[0028] When processing the dust and solid particles accumulated in the filter screen plate 41 and the sealing plate 42, it is only necessary to pull the handle 43 to pull the filter screen plate 41 to slide to the outside of the dust filter box 4. The filter screen plate 41 drives the sealing plate 42 to move synchronously through the linkage rod 44. The filter screen plate 41 can pull the mesh part out of the dust filter box 4 for cleaning. When the sealing plate 42 slides, the connecting opening between the dust filter box 4 and the crushing box 1 can be opened, so that the solid particles between the filter screen plate 41 and the sealing plate 42 fall into the crushing box 1 on the lower layer and mix into the crushed fragments.

[0029] Example 2

[0030] like Figure 1 to Figure 3 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that two rubber rings 61 are slidably sleeved on the outer wall of the sealing plate 42, and the rubber rings 61 are fixedly connected to the inner wall of the dust filter box 4; the dust filter box 4 is arranged to be inclined downward at one end close to the exhaust pipe 3, and when the sealing plate 42 slides and the dust filter box 4 is aligned with the crushing box 1, the accumulated solid particles can slide smoothly down along the inclined inner wall of the dust filter box 4 into the crushing box 1.

[0031] In this embodiment, the rubber ring 61 fills the gap between the sealing plate 42 and the side wall of the dust filter box 4, thereby improving the air tightness of the sealing plate 42 in blocking the opening of the dust filter box 4, so that the fan 5 can extract the air inside the dust filter box 4 to form an internal negative pressure to extract the air inside the exhaust pipe 3 with better effect.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
