[0002] Construction waste refers to construction waste generated by human or natural factors in the project, including waste soil, abandoned soil, silt and abandoned materials. These wastes have certain recycling value, so they are usually recycled and reused. The sorting device is a device that sorts construction waste in the process of recycling construction waste.

[0003] The construction waste sorting device mentioned in the existing Chinese public patent (authorization announcement number: CN219377367U) can first crush the construction waste mixed with metal parts by setting a crushing box, a crushing tool, a first conveyor belt, a second conveyor belt and a magnet, and then use the conveyor belt with a built-in magnet to suck up the crushed metal and transport it outward, thereby sorting the metal in the construction waste, improving the sorting efficiency, reducing labor costs, and enhancing work safety.

[0004] When sorting construction waste, most of the existing methods use crushing rollers to crush the construction waste to improve the recycling rate. However, in the process of crushing the construction waste, due to the presence of concrete waste in the construction waste, dust may appear during the crushing, and the dust will float out through the feeding port, bringing certain risks to the safety of the workers. Utility Model Content

[0005] The purpose of the present application is to provide a construction waste sorting device to solve the problem that dust may appear during crushing, and the dust will float out through the feeding port, posing a certain risk to the safety of the workers.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0008] By adopting the above technical scheme, construction waste is put into the feed pipe, and the construction waste in the feed pipe enters the discharge pipe through gravity, and is crushed by the crushing roller, and then the crushed waste falls on the filter plate, and is screened by the filter plate so that the waste with smaller particle size falls into the collection box, while the waste with larger particle size rolls through the inclined surface of the filter plate and is discharged from the discharge port, thereby completing the screening of the construction waste. The anti-blocking mechanism can make the filter plate vibrate to reduce the risk of filter plate blockage, and the dust collecting mechanism can collect the dust scattered during the crushing, thereby reducing the number of workers. To reduce the risk of accidental inhalation by workers, the dust enters the air inlet duct through the air inlet duct, and the dust inside the air inlet duct eventually enters the dust collecting box, and the dust entering the dust collecting box will be adsorbed by the electrostatic dust collecting plate. When the electrostatic dust collecting plate needs to be cleaned, the electrostatic dust collecting plate is pulled to slide inside the dust collecting box, so that the electrostatic dust collecting plate is pulled out and cleaned, so that the electrostatic dust collecting plate maintains a good adsorption effect. After the construction waste is crushed, the fan is started to blow air towards the air outlet. At this time, the air pulls the dust inside the feed pipe into the air inlet duct, reducing the risk of dust dispersion.

[0010] By adopting the above technical solution, when the electrostatic dust collecting plate slides inside the positioning parts on both sides, the card block will contact the electrostatic dust collecting plate. The card block will shrink when subjected to pressure, causing the elastic part to shrink when subjected to force, and elastic potential energy will be generated when the elastic part shrinks.

[0011] Furthermore, a card slot is provided on the top of the electrostatic dust collecting plate, and the card block and the card slot are both arranged in a semicircular shape, and the card block is adapted to the card slot.

[0012] By adopting the above technical solution, when the card block moves to the card slot position, the elastic potential energy of the elastic member 1 is released, so that the card block enters the interior of the card slot, so that the position of the electrostatic dust collecting plate is fixed, making the electrostatic dust collecting plate more stable when in use.

[0013] Furthermore, the anti-blocking mechanism includes a fixed box fixedly connected to the inner wall of one side of the working box, and an elastic member 2 is arranged inside the fixed box.

The elastic member 2 generates elastic potential energy under force. When the vibration component moves away from the filter plate, the elastic potential energy of the elastic member 2 is released, so that the filter plate is reset.

[0015] Furthermore, the vibration assembly includes a rotating motor fixedly connected to one side of the working box, the output end of the rotating motor passes through the working box and is fixedly connected to a striking block, and the striking block contacts the top of the filter plate when rotating.

[0016] By adopting the above technical solution, the rotating motor is started, and the rotating motor starts to drive the striking block to rotate. The striking block will resist the filter plate when rotating. By constantly resisting the filter plate, the granular matter inside the filter plate will be affected by the vibration force and move.

[0017] Furthermore, guide blocks are fixedly connected to the inner walls on both sides of the feed pipe, and the guide blocks are arranged at an angle.

[0018] By adopting the above technical solution, the construction waste dropped into the feed pipe can be effectively put into the discharge pipe through the guide block. At the same time, the guide block can play a certain protective effect when the construction waste is crushed.

[0019] In summary, the present application includes at least one of the following beneficial effects:

[0020] 1. In the present application, when construction waste is crushed, the fan is first started so that the fan blows air toward the air outlet. At this time, the air pulls the dust inside the feed pipe into the air inlet pipe, and the dust entering the air inlet pipe eventually enters the dust collecting box. The dust entering the dust collecting box will be adsorbed by the electrostatic dust collecting plate. When the electrostatic dust collecting plate needs to be cleaned, the electrostatic dust collecting plate is pulled to slide inside the dust collecting box, so that the electrostatic dust collecting plate is pulled out and cleaned, so that the electrostatic dust collecting plate maintains a good adsorption effect, and the dust is pulled into the dust collecting box to be collected, thereby reducing the risk of dust dispersion and improving the safety of the working environment.

[0021] 2. In the present application, when the filter plate filters construction waste, the rotating motor is started, and the rotating motor starts to drive the striking block to rotate. The striking block will contact the filter plate when rotating. The filter plate moves downward after being subjected to force. After the filter plate moves downward, it squeezes the elastic member 2. The elastic member 2 generates elastic potential energy under force. When the striking block moves away from the filter plate, the elastic potential energy of the elastic member 2 is released, causing the filter plate to reset. By continuously contacting the filter plate, the granular matter inside the filter plate will be affected by the vibration force and move, causing particles that may have originally blocked the filter plate to fall off the filter plate, thereby keeping the filter plate unobstructed and reducing the risk of clogging the filter plate.

[0030] The following is combined with Figures 1 to 6 This application is described in further detail.

[0031] The embodiment of the present application discloses a construction waste sorting device.

[0032] Reference Figures 1 to 4A construction waste sorting device comprises a base 1, a working box 2 is fixedly connected to the top of the base 1, a feeding pipe 3 is fixedly connected to the top of the working box 2, the feeding pipe 4 is connected to the feeding pipe 3, two crushing rollers 5 are symmetrically arranged inside the feeding pipe 3, a driving motor 6 is fixedly connected to one side of the feeding pipe 3, a pulley 1 is fixedly connected to the outer surface of the output end of the driving motor 6, and a transmission roller 5 is sleeved on the outer surface of the pulley 1.

The driving rod 8 is rotatably connected to the discharge pipe 3. A collecting box 9 is fixedly connected to the inner bottom wall of the working box 2. A filter plate 22 is rotatably connected to the inner wall of the working box 2. The filter plate 22 is inclined. A discharge port 10 is provided on one side of the working box 2. A box door 27 is hinged on one side of the working box 2. The working box 2 An anti-blocking mechanism is provided on the inner wall of one side, a dust collecting mechanism is provided on one side of the working box 2, and the dust collecting mechanism includes a mounting plate 11 fixedly connected to one side of the working box 2, a dust collecting box 12 is fixedly connected to the top of the mounting plate 11, a box door 2 is hinged on one side of the dust collecting box 12, an air inlet pipe 13 is fixedly connected to the top of the dust collecting box 12, the air inlet pipe 13 is connected to the dust collecting box 12, and one end of the air inlet pipe 13 away from the dust collecting box 12 passes through the feeding pipe 4, and an electrostatic dust collecting plate 16 is slidably connected to the inside of the dust collecting box 12. In the strong electric field, air molecules are ionized into positive ions and electrons. When the electrons rush to the positive electrode, they encounter dust, causing the dust to be negatively charged and adsorbed to the positive electrode so that it is collected by the electrostatic dust collecting plate 16. The inner wall of the dust collecting box 12 is provided with a snap-fit ​​assembly. The top of the mounting plate 11 is fixedly connected with a traction box 14, which is connected to the dust collecting box 12. An air outlet 15 is provided at one end of the traction box 14 away from the dust collecting box 12. A fan 28 is provided inside the traction box 14, and the blowing end of the fan 28 matches the air outlet 15.

[0033] When sorting construction waste, first put the construction waste into the feed pipe 4, and the construction waste in the feed pipe 4 enters the discharge pipe 3 by gravity. At this time, the drive motor 6 is started, and the drive motor 6 drives the two crushing rollers 5 inside the discharge pipe 3 to rotate. The rotation of the crushing rollers 5 can crush the construction waste in the discharge pipe 3, and then the crushed garbage falls on the filter plate 22. After the screening of the filter plate 22, the garbage with smaller particle size falls into the collection box 9, while the garbage with larger particle size will roll through the inclined surface of the filter plate 22 and be discharged from the discharge port 10 for re-crushing and other treatments, thereby completing the construction screening. When the filter plate 22 filters the garbage, the filter plate 22 can be vibrated by the anti-blocking mechanism. To reduce the risk of clogging of the filter plate 22, when the construction waste is crushed, the fan 28 is first started so that the fan 28 blows air toward the air outlet 15. At this time, the air pulls the dust inside the feed pipe 4 into the air inlet pipe 13, and the dust entering the air inlet pipe 13 eventually enters the dust box 12. The dust entering the dust box 12 will be adsorbed by the electrostatic dust collecting plate 16. When the electrostatic dust collecting plate 16 needs to be cleaned, the electrostatic dust collecting plate 16 is pulled to slide inside the dust box 12, so that the electrostatic dust collecting plate 16 is pulled out and cleaned, so that the electrostatic dust collecting plate 16 maintains a good adsorption effect, and the dust is pulled into the dust box 12 to be collected, thereby reducing the risk of dust dispersion and improving the safety of the working environment.

[0034] Reference Figure 4 and Figure 5 The engaging assembly includes positioning blocks 17 fixedly connected to the inner walls on both sides of the dust collecting box 12, and the positioning blocks 17 on both sides are slidably arranged with the electrostatic dust collecting plate 16. An empty groove 18 is opened inside the positioning block 17 on one side, and an elastic member 19 is arranged inside the empty groove 18. The elastic member 19 is composed of a telescopic rod and a spring. The top of the elastic member 19 is fixedly connected to the inner wall of the empty groove 18, and the bottom of the elastic member 19 is fixedly connected to a card block 20, which conflicts with the electrostatic dust collecting plate 16.

[0035] A card slot 21 is provided on the top of the electrostatic dust collecting plate, and both the card block 20 and the card slot 21 are configured in a semicircular shape, so that the card block 20 and the card slot 21 are matched with each other.

[0036] When the electrostatic dust collecting plate 16 needs to be placed inside the dust collecting box 12, the electrostatic dust collecting plate 16 is placed between the positioning blocks 17 on both sides. When the electrostatic dust collecting plate 16 slides inside the positioning blocks 17 on both sides, the block 20 will contact the electrostatic dust collecting plate 16. The block 20 will shrink after being subjected to pressure, causing the elastic member 19 to shrink under force. After the elastic member 19 shrinks, elastic potential energy is generated. When the block 20 moves to the position of the slot 21, the elastic potential energy of the elastic member 19 is released, allowing the block 20 to enter the interior of the slot 21, so that the position of the electrostatic dust collecting plate 16 is fixed, making the electrostatic dust collecting plate 16 more stable when in use. When it needs to be taken out, the shape of the block 20 and the slot 21 is set to be semicircular, and a certain pressure is applied. Under the sliding action of the arc surface, the elastic member 19 can be compressed, thereby taking out the electrostatic dust collecting plate 16, thereby facilitating the cleaning of the electrostatic dust collecting plate 16 and improving the adsorption effect of the electrostatic dust collecting plate 16.

[0037] Reference Figure 3 and Figure 6 The anti-blocking mechanism includes a fixed box 23 fixedly connected to the inner wall of one side of the working box 2, and an elastic member 24 is arranged inside the fixed box 23. The elastic member 24 is composed of a telescopic rod and a spring. The bottom end of the elastic member 24 is fixedly connected to the inner wall of the fixed box 23, and the top end of the elastic member 24 abuts against the filter plate 22. A vibration component is arranged on one side of the working box 2.

[0038] The vibration assembly includes a rotating motor 25 fixedly connected to one side of the working box 2. The output end of the rotating motor 25 passes through the working box 2 and is fixedly connected to a striking block 26. When the striking block 26 rotates, it contacts the top of the filter plate 22.

[0039] When the filter plate 22 filters construction waste, the rotating motor 25 is started, and the rotating motor 25 starts to drive the striking block 26 to rotate. The striking block 26 will contact the filter plate 22 when rotating. The filter plate 22 moves downward after being subjected to force. After the filter plate 22 moves downward, it squeezes the elastic member 24. The elastic member 24 generates elastic potential energy under force. When the striking block 26 moves away from the filter plate 22, the elastic potential energy of the elastic member 24 is released, so that the filter plate 22 is reset. By continuously resisting the filter plate 22, the granular matter inside the filter plate 22 will be affected by the vibration force and move, so that the particles that may originally block the filter plate 22 fall off the filter plate 22, thereby keeping the filter plate 22 unobstructed and reducing the risk of blockage of the filter plate 22.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The inner walls on both sides of the feed pipe 4 are fixedly connected with guide blocks 29, and the guide blocks 29 are arranged at an angle.

[0041] The guide block 29 allows the construction waste dropped into the feed pipe 4 to be effectively placed into the discharge pipe 3 . Meanwhile, the guide block 29 can provide a certain degree of protection when the construction waste is crushed.

[0042] Working principle: When sorting construction waste, first put the construction waste into the feed pipe 4, the construction waste in the feed pipe 4 enters the discharge pipe 3 by gravity, and the construction waste in the discharge pipe 3 is crushed by the crushing roller 5, and then the crushed waste falls on the filter plate 22. After the screening of the filter plate 22, the waste with smaller particle size falls into the collection box 9, while the waste with larger particle size rolls through the inclined surface of the filter plate 22 and is discharged from the discharge port 10, thereby completing the construction screening. By starting the fan 28, so that the fan 28 blows air toward the air outlet 15, and the air draws the dust inside the feed pipe 4 into the air inlet pipe 13, and the dust entering the air inlet pipe 13 finally enters the dust collecting box 12, and the dust entering the dust collecting box 12 will be adsorbed by the electrostatic dust collecting plate 16. When the electrostatic dust collecting plate 16 needs to be cleaned, the electrostatic dust collecting plate 16 is pulled to slide inside the dust collecting box 12, so that the electrostatic dust collecting plate 16 is pulled out and cleaned, so that the electrostatic dust collecting plate 16 maintains a good adsorption effect.

[0043] When the filter plate 22 filters construction waste, the rotating motor 25 is started, and the rotating motor 25 starts to drive the striking block 26 to rotate. The striking block 26 will contact the filter plate 22 when rotating. The filter plate 22 moves downward after being subjected to force. After the filter plate 22 moves downward, it squeezes the elastic member 24. The elastic member 24 generates elastic potential energy under force. When the striking block 26 moves away from the filter plate 22, the elastic potential energy of the elastic member 24 is released, so that the filter plate 22 is reset. By continuously contacting the filter plate 22, the granular matter inside the filter plate 22 will be affected by the vibration force and move.
