Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a dustproof structure for a concrete crusher. Background Technology

[0002] Concrete crushers generate a large amount of dust during the crushing process, which not only pollutes the environment but may also affect workers' health. Therefore, the dust control design of concrete crushers should be optimized based on the specific working environment, crusher model, and usage requirements. Effective dust control measures can protect the health of operators, reduce environmental pollution, and ensure the normal operation of the equipment. By using enclosed dust hoods, spray dust suppression, negative pressure ventilation, and dust collection devices, the dust problem generated during the crushing process can be significantly reduced.

[0003] The publication number is CN219849831U. This utility model relates to the field of concrete crusher technology and proposes a dustproof structure for a concrete crusher. The structure includes a crusher with a dust collection box on one side. Water is fixedly connected to the bottom of the dust collection box. By incorporating the dust collection box and an air pump, this utility model allows for efficient operation. When the air pump is activated, it creates suction in the suction pipe, drawing dust from inside the crusher into the dust collection box. Then, the water pump is activated, pumping water from the bottom of the dust collection box into a water supply pipe. This water then flows into an inlet pipe and a distribution pipe. Water from the distribution pipe then flows into a second outlet pipe and is distributed through a high-pressure nozzle. Water entering the inlet pipe flows into a rotating nozzle and is sprayed out. Therefore, the combined effect of the rotating and high-pressure nozzles rapidly reduces dust inside the crusher, thus minimizing dust discharge.

[0004] The device is equipped with a dust extraction system before crushing, but the dust generated by the splashed concrete during and after crushing is also relatively large. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a dustproof structure for a concrete crusher.

[0006] This utility model is achieved by the following technical solution: a dustproof structure for a concrete crusher, including a dust collection mechanism, a dust suppression mechanism and a drive mechanism, wherein the dust suppression mechanism is located inside the dust collection mechanism and the drive mechanism is located inside the dust collection mechanism.

[0007] The dust collection mechanism includes a crusher, a dust collection pipe is connected to the right side of the crusher, a splash baffle is fixedly connected to the left side of the inner wall of the dust collection pipe, a motor is fixedly connected to the outer wall of the dust collection pipe, a motor rotating rod is fixedly connected to the output end of the motor, the outer wall of the motor rotating rod is rotatably connected to the inner wall of the dust collection pipe, a fan blade is fixedly connected to the outer wall of the motor rotating rod, and a dust settling box is connected to the end of the dust collection pipe away from the crusher.

[0008] As a further improvement to the above solution, several suction pipes are provided, and two motors are provided, which are symmetrically arranged around the center of the dust collection box.

[0009] Using the above technical solution, symmetrically arranged motors are operated, causing the motor output end to rotate the motor rotating rod. The motor rotating rod rotates the fan blades, causing the fan blades to transport the dust generated before and after crushing inside the crusher into the dust collection box through the dust suction pipe.

[0010] As a further improvement to the above solution, the dust suppression mechanism includes a liquid storage box, which is slidably connected to the inner wall of the dust suppression chamber. A water pump is fixedly connected to the surface of the liquid storage box. An inlet pipe is connected to the left side of the water pump, and an outlet pipe is connected to the right side of the water pump. A nut is threaded onto the outer wall of the outlet pipe.

[0011] As a further improvement to the above solution, a connecting hose is slidably connected to the inner wall of the nut, and a second nut is slidably connected to the end of the connecting hose away from the nut. A liquid transfer pipe is threadedly connected to the inner wall of the second nut.

[0012] As a further improvement to the above solution, the end of the liquid transfer pipe away from the second nut is connected to the top of the inner wall of the dust settling box, the top of the inner wall of the dust settling box is rotatably connected to a rotating rod, the bottom of the rotating rod is fixedly connected to a guide plate, and the outer wall of the guide plate is connected to a fan blade.

[0013] As a further improvement to the above solution, dust collection holes are provided on the surface of the second fan blade, and three second fan blades are provided, which are evenly arranged around the guide plate.

[0014] With the above technical solution, when it is necessary to reduce dust in the gas inside the dust collection box, the water pump is operated. The water pump transports the liquid inside the liquid storage box to the outlet pipe through the water inlet pipe on the left side. At the same time, the outlet pipe transports the liquid to the connecting hose, the connecting hose transports the liquid to the liquid transmission pipe, and then the liquid inside the liquid transmission pipe is transported to the rotating rod. The liquid inside the rotating rod is then input downward into the guide plate.

[0015] As a further improvement to the above solution, the driving mechanism includes a drive motor, the bottom of which is fixedly connected to the top of the dust settling box. A second motor rotating rod is fixedly connected to the output end of the drive motor. The outer wall of the second motor rotating rod is rotatably connected to the inner wall of the dust settling box. A gear is fixedly connected to the end of the second motor rotating rod away from the drive motor. The gear meshes with a second gear, and the inner wall of the second gear is fixedly connected to the outer wall of the rotating rod.

[0016] Through the above technical solution, the drive motor is operated, the output end of the drive motor rotates the second motor rotating rod, the second motor rotating rod rotates the gear, the gear meshes with the second gear, the second gear rotates the rotating rod, the rotating rod rotates the guide plate, and the guide plate rotates the second fan blade.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes symmetrically arranged motors to rotate the motor's output rod, which in turn rotates the fan blades. These blades then transport the dust generated before and after crushing within the crusher through a suction pipe into the dust settling box. Simultaneously, a splash baffle on the left side of the suction pipe's inner wall blocks the concrete splashed before and after crushing, preventing it from entering the dust settling box through the suction pipe. This prevents concrete from affecting equipment operation and extends the equipment's service life.

[0019] This invention utilizes a water pump to suppress dust in the air inside the dust collection chamber when dust needs to be reduced. The water pump delivers liquid from the liquid storage box to the outlet pipe via the inlet pipe on the left side. Simultaneously, the outlet pipe delivers liquid to the connecting hose, which in turn delivers it to the liquid transfer pipe. The liquid in the liquid transfer pipe then flows into the rotating rod, which in turn sends the liquid downwards into the guide plate. The liquid in the guide plate is then diverted to the second fan blade, which sprays downwards through the dust suppression holes. This process effectively suppresses dust in the air inside the dust collection chamber. The dust particles are adhered to by the liquid and then return to the liquid storage box along with the liquid, allowing for repeated use of the liquid in the storage box.

[0031] The dust collection mechanism 1 includes a crusher 101. A dust collection pipe 102 is connected to the right side of the crusher 101. A splash baffle 103 is fixedly connected to the left side of the inner wall of the dust collection pipe 102. A motor 104 is fixedly connected to the outer wall of the dust collection pipe 102.

A fan blade 106 is fixedly connected to the outer wall of the motor rotating rod 105. A dust settling box 107 is connected to the end of the dust collection pipe 102 away from the crusher 101.

[0032] The suction pipe 102 has several parts, and there are two motors 104. The two motors 104 are symmetrically arranged with respect to the center of the dust box 107.

[0033] The dust collection mechanism 2 includes a liquid storage box 201, which is slidably connected to the inner wall of the dust collection box 107. A water pump 202 is fixedly connected to the surface of the liquid storage box 201. A water inlet pipe 203 is connected to the left side of the water pump 202, and a water outlet pipe 204 is connected to the right side of the water pump 202. A nut 205 is threadedly connected to the outer wall of the water outlet pipe 204.

[0034] A connecting hose 206 is slidably connected to the inner wall of nut 205. A second nut 207 is slidably connected to the end of the connecting hose 206 away from nut 205. A liquid transfer tube 208 is threadedly connected to the inner wall of the second nut 207.

[0035] One end of the liquid transfer pipe 208 away from the nut 207 is connected to the top of the inner wall of the dust settling box 107. A rotating rod 209 is rotatably connected to the top of the inner wall of the dust settling box 107. A guide plate 210 is fixedly connected to the bottom of the rotating rod 209. A fan blade 211 is connected to the outer wall of the guide plate 210.

[0036] Dust collection holes 212 are provided on the surface of the second fan blade 211. There are three second fan blades 211, which are evenly arranged around the guide plate 210.

[0037] The drive mechanism 3 includes a drive motor 301. The bottom of the drive motor 301 is fixedly connected to the top of the dust settling box 107. The output end of the drive motor 301 is fixedly connected to a second motor rotating rod 302. The outer wall of the second motor rotating rod 302 is rotatably connected to the inner wall of the dust settling box 107. The end of the second motor rotating rod 302 away from the drive motor 301 is fixedly connected to a gear 303. The gear 303 is meshed with a second gear 304. The inner wall of the second gear 304 is fixedly connected to the outer wall of the rotating rod 209.

[0038] The implementation principle of a dustproof structure for a concrete crusher in this embodiment is as follows: When the crusher 101 is crushing, the symmetrically arranged motors 104 are operated, causing the output end of the motor 104 to rotate the motor rotating rod 105. The motor rotating rod 105 rotates the fan blades 106, causing the fan blades 106 to transport the dust splashed inside the crusher 101 before and after crushing into the dust collection box 107 through the dust suction pipe 102. At the same time, the splash baffle 103 on the left side of the inner wall of the dust suction pipe 102 removes the splashed dust before and after crushing. Concrete is used as a barrier to prevent splashed concrete from entering the dust collection box 107 through the dust suction pipe 102 during the crushing process, thus preventing concrete from affecting equipment operation and extending equipment lifespan. When dust is collected from the air inside the dust collection box 107, water pump 202 is operated. Water pump 202 transports liquid from the liquid storage box 201 to the outlet pipe 204 through the left-side inlet pipe 203. Simultaneously, the outlet pipe 204 transports liquid to the connecting hose 206, which in turn transports liquid to the liquid transfer pipe 208. The liquid is then transported from the liquid transfer pipe 208 to the rotating rod 209. The liquid inside the rotating rod 209 flows downwards into the guide plate 210, where it is then diverted to the second fan blade 211. The liquid is sprayed downwards through the dust collection holes 212 on the second fan blade 211, thus suppressing dust in the air inside the dust collection box 107. The dust is adhered to by the liquid and then returns to the liquid storage box 201 along with the liquid, allowing for repeated use of the liquid inside the storage box 201. By operating the drive motor 301, the output end of the drive motor 301 rotates the motor rotating rod 302, the motor rotating rod 302 rotates the gear 303, the gear 303 meshes with the gear 304, the gear 304 rotates the rotating rod 209, the rotating rod 209 rotates the guide plate 210, the guide plate 210 rotates the fan blade 211, so that the fan blade 211 suppresses the air flying inside the dust settling box 107. While the fan blade 211 is rotating, the spray range of the dust settling hole 212 will be wider, making the dust settling effect more obvious.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
