[0032] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0033] Reference Figures 1 to 6As shown, this utility model provides a technical solution: a solid waste crushing and screening device, including a crushing component 1; a screening component 2 is arranged inside the crushing component 1, the crushing component 1 includes a crushing box 11, a motor A12 is fixedly connected to one side of the crushing box 11, a crushing roller 13 is rotatably installed inside the crushing box 11, the output end of the motor A12 is fixedly connected to the crushing roller 13, a screening box 14 is fixedly connected to the bottom surface of the crushing box 11, a screening groove 15 is opened on the screening box 14, a discharge port A16 is opened on the other side of the screening box 14, an inclined plate 17 is fixedly connected to the inner wall of the screening box 14, and a discharge port B18 is arranged below the discharge port A16. 18 is opened on the screening box 14. The screening component 2 includes a screening frame 21, which is installed in the screening trough 15. The screening frame 21 has an installation groove 22, and a screening plate 23 is installed in the installation groove 22. The screening plate 23 is set above the inclined plate 17. An anti-blocking shaft 24 is set below the screening plate 23. A rubber rod 25 is installed on the anti-blocking shaft 24. A discharge shaft 26 is set below the anti-blocking shaft 24. A discharge wheel 27 is fixedly connected to the outer surface of the discharge shaft 26. Both the anti-blocking shaft 24 and the discharge shaft 26 are rotatably installed inside the screening box 14. A motor B28 is installed on one side of the screening box 14. The motor B28 is matched with the anti-blocking shaft 24 and the discharge shaft 26.
[0034] The operator adds the solid waste to be crushed into the crushing box 11. Two sets of motors A12 drive the crushing rollers 13 to rotate, crushing the solid waste. The crushed waste enters the screening box 14 from the crushing box 11 and then falls directly onto the screening plate 23. Since the screening plate 23 is installed at an angle, the waste slides on the screening plate 23 under the influence of gravity. Smaller waste particles pass through the screening plate 23 and fall onto the inclined plate 17, and then are discharged from the discharge port B18 into the screening box 14. Larger particles remain on the screening plate 23. The particles are discharged from the discharge port A16 into the screening box 14. During this process, the motor B28 provides power to the anti-blocking shaft 24 and the discharge shaft 26, causing the anti-blocking shaft 24 to drive the rubber rod 25 to rotate. The rotating rubber rod 25 will intermittently hit the screening plate 23, thereby removing the particles blocked on the screening plate 23 and accelerating the rate of waste removal from the screening plate 23, thus reducing the number of times the machine needs to be stopped to clean the screening plate 23. At the same time, the discharge shaft 26 will drive the discharge wheel 27 to move, cleaning the waste on the inclined plate 17 and accelerating the rate of waste removal.

[0036] A set of feed hoppers 111 is installed on the crushing box 11 to increase the size of the feed inlet of the crushing box 11, making it easier for operators to add waste into the crushing box 11. Then, the crushing operation of the waste is achieved under the joint action of two sets of motors A12 and crushing rollers 13.
[0037] Reference Figures 1 to 3 As shown, this utility model provides a technical solution: a crushing and screening device for solid waste.

The two sets of discharge hoppers 19 correspond to the discharge port A16 and the discharge port B18, respectively.
[0038] The threaded post 141 and nut 142 make it easier for operators to operate the screening frame 21. When it is necessary to manually clean the screening plate 23, the screening frame 21 can be easily pulled out from the screening box 14, and then the screening plate 23 can be operated directly. Furthermore, the addition of the discharge hopper 19 makes it easier to discharge the screened waste from the screening box 14.
[0039] Reference Figures 2 to 6 As shown, this utility model provides a technical solution: a solid waste crushing and screening device, wherein one end of an anti-clogging shaft 24 extends through the screening box 14 to its outside, and a pulley A241 is fixedly connected to one end of the anti-clogging shaft 24; one end of a discharge shaft 26 extends through the screening box 14 to its outside, and a pulley B261 is fixedly connected to one end of the discharge shaft 26; pulleys C281 and D282 are fixedly connected to the output end of a motor B28; belts A283 are fitted on the outer surfaces of pulleys A241 and C281; belts B284 are fitted on the outer surfaces of pulleys B261 and D282; a rubber ball is fixedly connected to one end of a rubber rod 25; the rubber rod 25 is fixedly installed on the anti-clogging shaft 24 by bolts; the rubber rod 25 matches the screening plate 23; a protective cover 29 is installed on one side of the screening box 14; the motor B28 is located inside the protective cover 29; and multiple sets of exhaust holes 291 are opened on the protective cover 29.
[0040] By setting pulleys A241, B261, C281, D282, belts A283 and B284, motor B28 can simultaneously drive anti-blocking shaft 24 and discharge shaft 26, enabling them to work normally.
