[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a construction waste crusher, including a frame 1, a crushing box 2 is provided on the top of the frame 1, a feed box 3 is fixedly connected to the top outer wall of the crushing box 2, a discharge box 4 is fixedly connected to the bottom outer wall of the frame 1, a crushing roller 5 is rotatably connected to the inner wall of the crushing box 2, there are two crushing rollers 5, the two crushing rollers 5 are meshed, the crushing rollers 5 are rotatably connected to the crushing box 2 through a rotating shaft, a gear 7 is fixedly connected to one end of each of the two crushing rollers 5, the two gears 7 are meshed, a motor 6 is fixedly connected to the top outer wall of the frame 1, and the output shaft of the motor 6 is connected to one end of one of the rotating shafts;

[0026] A guide plate 8 is fixedly connected to the inner wall of the feeding box 4. The guide plate 8 is alternately arranged on the inner wall of the feeding box 4. A conveyor belt 9 is arranged on the upper part of the frame 1 below the feeding box 4. A dust collection device 10 is fixedly connected to the outer wall of the frame 1 and on one side of the crushing box 2.

[0027] The vacuuming device 10 includes a purification box 101, a door 102 hinged to the outer wall of the purification box 101, a vacuuming pipe 103 fixedly connected to the inner wall of the purification box 101, the other end of the vacuuming pipe 103 fixedly connected to the inner wall of the feed box 3, a fan 104 installed on one side of the outer wall of the purification box 101, a water tank 108 fixedly connected to one side of the outer wall of the purification box 101, a water pump installed inside the water tank 108, a water delivery pipe 109 fixedly connected to the output end of the water pump, a spray pipe 110 fixedly connected to the top outer wall of the purification box 101, a nozzle installed on the bottom outer wall of the spray pipe 110, a filter screen 105 installed on the inner wall of the purification box 101, and a collection box 107 slidably connected to the inner wall of the purification box 101 and below the filter screen 105.

[0028] In this implementation plan, construction waste is slid into the crushing box 2 at an angle through the feeding box 3. The motor 6 is started to drive the crushing roller 5 to squeeze and shear the construction waste, breaking large pieces of construction waste into smaller particles. The crushed construction waste falls from the crushing box 2 into the feeding box 4. The guide plates 8, which are alternately arranged at an angle inside the feeding box 4, cause the construction waste to slide down in stages, effectively slowing down the speed of the construction waste as it falls, greatly reducing the large amount of dust generated by direct falling. Finally, the crushed construction waste falls from the feeding box 4 onto the conveyor belt 9 below, which transports it to a designated location for subsequent processing.

[0029] During crushing, the dust generated in the crushing box 2 rises into the feeding box 3. The fan 104 installed on the outer wall of one side of the purification box 101 starts. The fan 104 generates a strong suction, creating a negative pressure environment in the dust suction pipe 103, which causes the dust to be sucked into the purification box 101 along the dust suction pipe 103. The water pump inside the water tank 108 is started. The water pump delivers the water in the water tank 108 to the spray pipe 110 through the water delivery pipe 109. The water is sprayed out from the nozzle at the bottom of the spray pipe 110. The sprayed water carries the dust down. The filter screen 105 intercepts the solid particles in the water. The collection box 107 collects the falling wastewater, ensuring that the dust content of the exhaust air is greatly reduced. When it is necessary to clean the collection box 107 or replace or clean the filter screen 105, the hinged door 102 on the outer wall of the purification box 101 can be opened, and the filter screen 105 can be pulled out along the slide rail 106 on the inner wall.

[0030] The feed box 3 includes a horizontal extension section and an inclined guide section fixedly connected to the crushing box 2. The feed box 3 and the crushing box 2 are inclined.

[0031] This implementation plan effectively avoids material splashing during crushing operations, reduces the risk of injury to workers, and provides safety assurance for operators.

[0032] The guide plate 8 is set at an inclined angle, and the guide plate 8 is adjacent to the inner wall of the feeding box 4 on one side, and its height is higher than the side closer to the middle of the feeding box 4.

[0033] In this implementation plan, the crushed construction waste can slide down the guide plate 8 step by step during the falling process, which can effectively slow down the falling speed and avoid the material from raising a large amount of dust due to direct high-speed falling.

[0034] The outer wall of the feed box 3 is provided with a dust discharge port, and the purification box 101 is connected to the feed box 3 through the dust suction pipe 103.

[0035] The inner wall of the purification box 101 is provided with a slide rail 106, and the outer wall of the filter screen 105 is slidably connected to the inner wall of the slide rail 106.

[0036] In this embodiment, the purification box 101 is equipped with a hinged box door 102 and an internal slide rail 106, which makes it convenient to open the box door 102 to remove the filter screen when needed, clean the collection box 107, and replace or clean the filter screen 105, thereby reducing the difficulty and workload of equipment maintenance.

[0037] Among them, baffles 11 are fixedly connected to the outer wall of the frame 1 and on both sides of the conveyor belt 9.

[0038] In this embodiment, the baffle 11 can play a protective role during the feeding process, effectively preventing the material from splashing outside the equipment when it falls onto the conveyor belt 9.

[0039] Working principle: Construction waste slides into the crushing box 2 at an incline through the feed box 3. The feed box 3 includes a horizontal extension section and an inclined guide section fixedly connected to the crushing box 2. The feed box 3 and the crushing box 2 are set at an incline to avoid material splashing and injuring workers during crushing. After the motor 6 at the top of the frame 1 is turned on, its output shaft drives the rotating shaft of one of the crushing rollers 5 connected to it to rotate. Since the gears 7 at one end of the two crushing rollers 5 are meshed with each other, when one crushing roller 5 rotates, the other crushing roller 5 will rotate in the opposite direction under the transmission of the gear 7. The two relatively rotating crushing rollers 5 squeeze and shear the construction waste entering the crushing box 2, breaking large pieces of construction waste into smaller particles.

[0040] The crushed construction waste falls from the crushing box 2 into the feeding box 4. The guide plates 8, which are alternately installed at different heights and at an angle inside the feeding box 4, cause the construction waste to slide down in stages, effectively slowing down the speed of the construction waste as it falls and greatly reducing the large amount of dust generated by direct falling. Finally, the crushed construction waste falls from the feeding box 4 onto the conveyor belt 9 below, which transports it to a designated location for subsequent processing.

[0041] During pulverization, the fan 104 installed on one side of the outer wall of the purification chamber 101 starts. The fan 104 generates a strong suction force, creating a negative pressure environment in the dust suction pipe 103. This causes the dust generated in the pulverizing chamber 2 to be sucked into the purification chamber 101 along the dust suction pipe 103. The water pump inside the water tank 108 is started. The water pump delivers water from the water tank 108 to the spray pipe 110 through the water delivery pipe 109. The water is sprayed out from the nozzle at the bottom of the spray pipe 110. The sprayed water carries the dust down. The filter screen 105 intercepts the solid particles in the water. The collection box 107 collects the falling wastewater, ensuring that the dust content of the exhaust air is greatly reduced. When it is necessary to clean the collection box 107 or replace or clean the filter screen 105, the hinged door 102 on the outer wall of the purification chamber 101 can be opened, and the filter screen 105 can be pulled out along the slide rail 106 on the inner wall for operation, which is very convenient.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
