The front cover and the rear cover of the rack 2 are provided with a strip-shaped limiting groove 23 at the symmetrical position, and a cleaning mechanism 6 parallel to the sieve screen 4 is installed in the strip-shaped limiting groove 23. The cleaning mechanism 6 comprises a brush 61, a motor 62 connected to the upper end of the brush 61, and a rubber wheel 63 connected to the rotor of the motor 62. The brush 61 is mounted in the strip-shaped limiting groove 23 through the mounting blocks provided on both sides thereof, and the rim of the rubber wheel 63 abuts against the inner wall of the rear cover of the rack 2.

[0024] Specifically, the rack 2 is in a box-shaped structure, the inlet 21 is provided on the upper cover of the rack 2, the material enters the crushing cavity in the rack 2 from top to bottom, and is discharged through the sieve screen 4 after being impacted by the crushing main body 5. The sieve screen 4 is installed between the front cover and the rear cover of the rack 2, the strip-shaped limiting groove 23 is symmetrically provided in the inner walls of the front cover and the rear cover of the rack 2, and is arranged on one side of the outer surface of the sieve screen 4. In this way, the brush 61 installed in the strip-shaped limiting groove 23 can be parallel to the outer surface of the sieve screen 4. The brush 61 cleans the residual material on the surface of the sieve screen 4 when moving along the strip-shaped limiting groove 23, avoiding interference between the brush 61 and the crushing main body 5 or other components, and facilitating maintenance and replacement of the brush 61. The motor 62 is a forward and reverse motor. During the cleaning process of the sieve screen 61, the motor 62 drives the rubber wheel 63 to rotate, the rubber wheel 63 abuts against the inner wall of the rear cover of the rack 2, so that the cleaning mechanism 6 reciprocates along the strip-shaped limiting groove 23, the brush 61 sweeps the surface of the sieve screen 4, and the sieve screen 4 is prevented from being blocked.

[0025] Optionally, the above-mentioned brush 61 can be replaced by any one of a scraper, a dust suction unit, or a water spraying unit.

[0026] Continuing to refer to Figure 1In an implementation, the screen 4 is arc-shaped, the strip-shaped limiting groove 23 corresponds to the shape of the screen 4; the cleaning mechanism 6 is parallel to the screen plate frame 3 at the top end of the strip-shaped limiting groove 23 in the static state; and the cleaning mechanism 6 reciprocally moves along the strip-shaped limiting groove 23 in the working state.

[0027] Specifically, the arc-shaped structure of the screen 4 can be designed according to actual needs, such as U-shaped, semicircular or other arc-shaped, which is not limited in the present application. In order to ensure that the cleaning mechanism 6 can clean the entire surface of the screen 4, the shape of the strip-shaped limiting groove 23 should be adjusted according to the arc-shaped shape of the screen 4, corresponding to the shape thereof. In the static state, the cleaning mechanism 6 is arranged parallel to the screen plate frame 3 between the housings on both sides of the screen plate frame 3 and the rack 2. In this state, the cleaning mechanism 6 does not contact the screen 4 to avoid unnecessary wear. In the working state, the cleaning mechanism 6 reciprocally moves along the strip-shaped limiting groove 23 to remove the residual materials on the surface of the screen 4, ensuring the smoothness of the screen 4.

[0028] Preferably, the housings on both sides of the rack 2 can be designed in the shape of a rectangle or a trapezoid to provide a larger space for the cleaning mechanism 6 to move.

[0029] Figure 3 is a schematic diagram of part of the structure of a solid waste cementitious material mixing device in an embodiment of the present application. As shown in Figure 3 In an implementation, the solid waste cementitious material crushing device further comprises a left guide rod 11 and a right guide rod 12 installed on the upper end of the base 1, the left housing 24 of the rack 2 is installed on the left guide rod 11 and slides back and forth along the left guide rod 11, and the right housing 25 of the rack 2 is installed on the right guide rod 12 and slides back and forth along the right guide rod 12.

[0030] Specifically, the left housing 24 and the right housing 25 of the rack 2 are used to collect the materials passing through the screen 4. In conventional crushing devices, the rack 2 is often designed to be sealed to avoid dust pollution caused by material crushing. In the present embodiment, the guide rods 11 are arranged on the base 1 as support and sliding tracks, so that the left housing 24 and the right housing 25 of the rack 2 can slide back and forth on the corresponding guide rod on one side, providing a larger operation space for components such as the screen 4 or the cleaning mechanism 6, facilitating disassembly, assembly or maintenance. The right guide rod is not shown in the figure due to the angle of view.

[0031] Figure 4 is a schematic diagram of the cross-sectional structure of another solid waste cementitious material crushing device in an embodiment of the present application. As shown in Figure 4As shown, in an implementation mode, the screen 4 includes a first screen 41 and a second screen 42 which are axially separated along the crushing body 5, and the upper ends of the first screen 41 and the second screen 42 are respectively connected to the screen plate frame 3 on both sides of the feeding port 21, and the lower ends of the first screen 41 and the second screen 42 are both connected to the first support rod 7 which is installed below the crushing body 5.

[0032] Specifically, the screen 4 is axially separated into the first screen 41 and the second screen 42 along the crushing body 5, and the cleaning mechanism 6 should also be increased according to the number of the screen 4, including the first cleaning mechanism for cleaning the first screen 41 and the second cleaning mechanism for cleaning the second screen 42. In this way, the cleaning range of the cleaning mechanism 6 is reduced, and the cleaning mechanism 6 can be more fitted to the surface of the screen 4.

[0033] Continuing to refer to Figure 2 Preferably, the inner wall of the front cover and the rear cover of the frame 2 is provided with at least one fixing block 26 which is connected to the first screen 41 and the second screen 42 through bolts. This connection mode makes the installation of the first screen 41 and the second screen 42 more stable and can withstand greater material pressure.

[0034] Continuing to refer to Figure 1 The above crushing body 5 is a crushing component of a conventional hammer crusher, including a rotor, a hammer head, a lining plate, a motor and other components. The rotor is driven to rotate at high speed by the motor, and the hammer head impacts the material input by the feeding port 21 under the action of centrifugal force to achieve the crushing of the material. In an implementation mode, a guide plate 8 is arranged below the feeding port 21, and the inclination direction of the guide plate 8 is opposite to the rotation direction of the crushing body 5.

[0035] Specifically, the guide plate 8 can make the material slide to one side of the hammer head along the inclination direction of the guide plate 8 before entering the crushing cavity, and the inclination direction of the guide plate 8 is opposite to the rotation direction of the crushing body 5, which is helpful to effectively accelerate and disperse the material when it enters the crushing cavity, so as to uniformly impact the hammer head. It should be understood that the inclination angle of the guide plate 8 can be adjusted according to actual conditions, and the preferred inclination angle is 5-15 degrees.
