[0004] The top of the slag screening device in the aforementioned patent has an open structure. During the slag screening operation, the high-frequency vibrations generated cause a large amount of fine particles and dust in the slag to be stirred up, resulting in dust pollution. This flying dust not only pollutes the surrounding atmospheric environment but also reduces air quality. Summary of the Invention

[0005] To address the technical problem that existing construction waste screening devices have an open top structure, which causes high-frequency vibrations during screening operations to raise a large amount of fine particles and dust from the construction waste, resulting in dust pollution, this utility model provides a screening device for the environmentally friendly treatment of construction waste.

[0008] The present invention is further configured such that the drive assembly includes a fixed plate fixedly connected to the outside of the housing, a motor fixedly connected to the outside of the fixed plate, and a threaded rod fixedly connected to the output end of the motor. A nut block is threadedly connected to the outside of the threaded rod, and a movable frame is fixedly connected to the outside of the nut block. The movable frame is fixedly connected to the movable plate.

[0009] A further feature of this invention is that the top of the movable plate is provided with a slot, and two damping shafts are rotatably connected within the slot, with a limit plate fixedly connected to the outside of the damping shafts.

[0010] A further feature of this invention is that a first gear is fixedly connected to the outside of each damping shaft, a second gear is fixedly connected to the outside of each first gear, and a rack is fixedly connected to the outside of the housing, the rack meshing with the second gear.

[0011] A further feature of this invention is that a guide rod is fixedly connected to the outside of the fixing plate, and the guide rod passes through the nut block.

[0012] A further feature of this invention is that the screen is detachably and fixedly connected to the housing.

[0013] The beneficial effects of this invention are as follows: High-frequency vibration causes the slag to move continuously within the casing, ensuring full contact with the screen, thereby achieving the separation of slag with different particle sizes.

[0022] In the description of this utility model, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] The present invention will be further described below with reference to Figures 1-6.

[0024] To address the problems existing in the background technology, this application proposes the following technical solution: A screening device for environmentally friendly treatment of construction waste includes a frame 1, a housing 3 mounted on the frame 1, a spring 2 connecting the housing 3 to the frame 1, a vibrator 4 fixedly connected to the bottom of the housing 3, a screen 6 connected inside the housing 3, the screen 6 being detachably fixedly connected to the housing 3, a first discharge hopper 7 fixedly connected to one end of the housing 3, a second discharge hopper fixedly connected to one side of the bottom of the housing 3, a snap-fit ​​assembly on the outside of the housing 3, and a top cover 5 on the top of the housing 3, the top cover 5 being connected to the housing 3 via the snap-fit ​​assembly. The frame 1 serves as the basic support structure for the entire device, providing a stable installation platform for other components. The spring 2 connecting the housing 3 to the frame 1 acts as a buffer and shock absorber, effectively reducing the transmission of vibration to the ground when the vibrator 4 is working, reducing noise pollution, and protecting the frame 1 and other components from excessive impact, thus extending the service life of the equipment. The vibrator 4 at the bottom is the core power component for screening construction waste. Through high-frequency vibration, it causes the waste to move continuously within the housing 3, ensuring full contact with the screen 6 and thus separating waste of different particle sizes. The screen 6 uses a detachable fixed connection, facilitating quick replacement when it becomes clogged or damaged, ensuring continuous screening operations. The first discharge hopper 7 and the second discharge hopper 8 are used to discharge waste of different particle sizes, achieving graded treatment and improving the recycling rate. The snap-fit ​​assembly and the top cover 5 are also highlights. The top cover 5 effectively prevents dust from flying during screening, reducing air pollution and protecting the surrounding environment and the health of operators, meeting environmental protection requirements. This design allows the screening device to efficiently process construction waste while also considering environmental protection and equipment maintenance needs.

[0025] In this embodiment, both ends of the top cover 5 are provided with slots 22. The snap-fit ​​assembly consists of movable plates 15 disposed on both sides of the housing 3. A drive assembly is provided on the outside of the housing 3 to drive the movable plates 15 to move. The movable plates 15 correspond to the slots 22. The design of the snap-fit ​​assembly and the drive assembly provides a convenient and reliable solution for the installation and removal of the top cover 5. The slots 22 at both ends of the top cover 5 and the movable plates 15 on both sides of the housing 3 cooperate with each other to form a stable snap-fit ​​structure. The drive assembly, as a power source, can precisely control the movement of the movable plates 15 to ensure a tight connection between the top cover 5 and the housing 3. In actual operation, when the top cover 5 needs to be installed, the drive assembly is activated, driving the movable plates 15 to move towards the slots 22 until the movable plates 15 are fully inserted into the slots 22, thereby quickly fixing the top cover 5. Compared with traditional bolt fixing or snap-fit ​​fixing, this snap-fit ​​method is simpler and faster to operate, greatly saving installation time and improving work efficiency. Meanwhile, the stable snap-fit ​​structure ensures that the top cover 5 will not loosen or fall off due to vibration during the operation of the screening device, effectively preventing dust spillage and ensuring environmental protection. When the top cover 5 needs to be disassembled for maintenance or cleaning, the drive component reverses its direction, and the moving plate 15 exits from the slot 22, allowing the top cover 5 to be easily removed. This design makes the installation and disassembly of the top cover 5 more user-friendly, reduces the labor intensity of operators, and facilitates daily maintenance and upkeep of the equipment, ensuring the long-term stable operation of the screening device.

[0026] In this embodiment, the drive assembly includes a fixed plate 9 fixedly connected to the outside of the housing 3, a motor 10 fixedly connected to the outside of the fixed plate 9, and a threaded rod 12 fixedly connected to the output end of the motor 10. A nut block 14 is threadedly connected to the outside of the threaded rod 12, and a movable frame 13 is fixedly connected to the outside of the nut block 14. The movable frame 13 is fixedly connected to the movable plate 15. A guide rod 11 is fixedly connected to the outside of the fixed plate 9, and the guide rod 11 passes through the nut block 14. The drive assembly adopts a motor 10-threaded rod 12 transmission structure, which features simple structure, stable operation, and precise control. The fixed plate 9 is fixed to the outside of the housing 3, providing a stable mounting base for components such as the motor 10 and the threaded rod 12. The motor 10, as a power source, can provide stable and continuous power output. Through its connection with the threaded rod 12, the rotational motion of the motor 10 is converted into the linear motion of the nut block 14. When the motor 10 starts, it drives the threaded rod 12 to rotate. Because the nut block 14 is threadedly connected to the threaded rod 12, the nut block 14 moves linearly along the threaded rod 12. The movable frame 13, fixed externally to the nut block 14, is connected to the movable plate 15, thereby driving the movable plate 15 to move synchronously. The guide rod 11 on the outside of the fixed plate 9 passes through the nut block 14, playing a crucial guiding and stabilizing role, ensuring that the nut block 14 does not deviate or wobble during movement and always maintains a straight-line motion. The beneficial effects of this design are significant. By precisely controlling the rotation direction and number of revolutions of the motor 10, the moving distance of the movable plate 15 can be accurately adjusted, achieving a tight connection and easy separation between the upper cover 5 and the housing 3. Whether installing or removing the upper cover 5, the operator only needs to start or stop the motor 10 to complete the operation.

[0027] In this embodiment, the top of the movable plate 15 is provided with a slot 16, within which two damping shafts 19 are rotatably connected. A limit plate 17 is fixedly connected to the outside of each damping shaft 19, and a first gear 18 is fixedly connected to the outside of each damping shaft 19. A second gear 20 is fixedly connected to the outside of one of the first gears 18, and a rack 21 is fixedly connected to the outside of the housing 3, meshing with the second gear 20. This structure, through the gear-rack 21 transmission and the combination with the damping shafts 19, achieves automated and reliable locking of the upper cover 5. The damping shafts 19 within the slot 16 at the top of the movable plate 15 provide flexible and stable support for the rotation of the limit plate 17. The damping characteristics make the limit plate 17 more stable during rotation, preventing wobbling from affecting the locking effect. The arrangement of the first gear 18 and the second gear 20, together with the rack 21 outside the housing 3, constitutes a clever transmission system. When the movable plate 15 moves under the drive of the drive assembly, the second gear 20 meshes with the rack 21. As the movable plate 15 rises or falls, the rack 21 drives the second gear 20 to rotate, which in turn, through the meshing relationship between the first gears 18, causes the two limiting plates 17 to rotate synchronously outward or inward. When installing the upper cover 5, the limiting plates 17 rotate outward to open and abut against the outside of the upper cover 5, forming an additional locking force, which enhances the firmness of the connection between the upper cover 5 and the housing 3, ensuring that the upper cover 5 will not loosen even under high-intensity vibration of the screening device. When removing the upper cover 5, the limiting plates 17 rotate inward to retract, which does not obstruct the movable plate 15 from exiting the slot 22, ensuring a smooth disassembly process.

[0028] The usage method of this embodiment is as follows:

[0029] When installing the top cover 5, simply place the top cover 5 above the housing 3, then start the motor 10 to drive the threaded rod 12 to rotate. The threaded rod 12 drives the moving frame 13 to slide upward through the nut block 14 until the moving plate 15 is inserted into the slot 22. During the movement of the moving plate 15, the second gear 20 meshes with the rack 21, thereby driving the first gear 18 to rotate. The two first gears 18 mesh with each other, thereby driving the limiting plate 17 to rotate outward and open, abutting against the outside of the top cover 5, forming a lock on the top cover 5.

[0030] The slag to be screened is added into the housing 3 through the feed port of the top cover 5. The vibrator 4 is started to work, which drives the housing 3 to vibrate. The housing 3 drives the screen 6 to vibrate, thereby realizing the screening of the slag. After screening, the slag remaining on the upper layer of the screen 6 is discharged through the first discharge hopper 7, and the screened slag is discharged through the second discharge hopper 8.

[0031] The design of the top cover 5 can prevent dust from flying during the slag screening process, thus protecting the environment.

[0032] When the top cover 5 needs to be removed for maintenance, the same principle is reversed. Start the motor 10 to reverse, so that the moving plate 15 descends while the limiting plate 17 rotates in opposite directions to store it, allowing the moving plate 15 to leave the slot 22.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
