Description

Technical Field

[0001] This utility model relates to the field of building sand and gravel cleaning technology, and in particular to a building sand and gravel cleaning device. Background Technology

[0002] Sand and gravel refer to a loose mixture of sand and gravel. Before being used as building materials, sand and gravel need to be cleaned. To solve the problem of cleaning construction sand and gravel, existing technologies, such as Chinese Patent Publication No. CN221869556U, disclose a construction sand and gravel cleaning device. This device includes a cleaning tank with a cleaning mechanism inside, an adjustment mechanism below the tank, and a feed hopper above the tank. The bottom end of the feed hopper extends through the top surface of the cleaning tank into its interior. A discharge port is opened on the left side of the tank, and a second baffle is located to the left of the discharge port. Through the cleaning mechanism, the filtration device facilitates the filtration of water after cleaning the construction sand and gravel. Simultaneously, the vibration of the filter screen reduces impurities clogging the mesh, improving filtration efficiency. The cleaning components clean the construction sand and gravel, and the rotating stirring rod agitates and cleans the sand and gravel. A water pipe and pump recycle the filtered water, reducing resource waste and improving the device's environmental friendliness and cleaning efficiency.

[0003] However, during operation, the filter screen is easily worn due to the impact of sand and gravel impurities, requiring replacement periodically. Existing technologies typically employ either bolt-and-nut or drawer-type methods for disassembling and assembling filter screens. Bolt-and-nut methods are cumbersome and time-consuming; while drawer-type methods lack stability, allowing the filter screen to easily detach due to the impact of sand and gravel. To address these issues, a construction sand and gravel cleaning device is proposed. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] See Figures 1 to 8 This utility model provides a construction sand and gravel cleaning equipment, including a cleaning tank 1. The cleaning tank 1 has a first filtration zone 11 inside, a cleaning component inside the first filtration zone 11, and a filter device 6 below the cleaning component. The filter device 6 is located at the bottom of the first filtration zone 11.

[0028] The filtering device 6 includes a frame hinged to the inner wall of the cleaning tank 1. A filter screen 14 is mounted on the frame and slides back and forth relative to the frame. A locking device is provided within the frame to restrict the sliding of the filter screen 14 on the frame. Specifically, the raw material is cleaned in the first filtering zone 11 by the cleaning assembly to remove impurities, while the required sand and gravel are filtered out by the filtering device 6. The frame is hinged to the inner wall of the cleaning tank 1, allowing the frame to be flipped, providing working space for cleaning impurities on the filtering device 6 or replacing the filter screen 14. The filter screen 14 slides back and forth relative to the frame, allowing it to be removed from the frame. The locking device controls the stationary and sliding states of the filter screen 14. Therefore, the locking device enables quick installation and removal of the filter screen 14, improving operational efficiency. Simultaneously, the locking device also has a limiting function, restricting the sliding of the filter screen 14 and preventing it from easily detaching, thus improving the stability of the filter screen 14.

[0029] Specifically, the frame consists of a pair of long rods 15, which are slidably connected to the filter screen 14. One end of each long rod 15 is hinged to the cleaning tank 1. The latching device includes a movable rod 17 located inside the long rod 15 and sliding relative to it. A bushing 21 is provided on the movable rod 17, and a spring 22 is provided on one side of the bushing 21. One end of the spring 22 abuts against one end face of the bushing 21, and the other end abuts against the inner wall of the long rod 15. A movable claw 19 is provided inside the long rod 15, and a rotating shaft 20 is provided inside the long rod 15. The rotating shaft 20 rotates relative to the long rod 15 and is fixedly connected to the movable claw 19. A meshing tooth 18 is provided on the movable rod 17, which meshes with the movable claw 19. A connecting rod 16 is fixedly connected between the long rods 15. When the movable rod 17 slides, the bushing 21 compresses the spring 22. At this time, the meshing teeth 18 drive the movable pawl 19 to rotate. When the movable rod 17 returns to its original position under the elastic force of the spring 22, the movable pawl 19 also rotates under the meshing of the meshing teeth 18, completing the reset. The reset state of the movable rod 17 is fixed by the elastic force applied by the spring 22, and one end face of the movable rod 17 abuts against the inner wall of the long rod 15.

[0030] Specifically, a switch is provided between the connecting rod 16 and the long rod 15. The switch is used by the connecting rod 16 to control the start and stop of the movable rod 17. The switch includes a first pin 23 and a pin hole 24. The first pin 23 abuts against the pin hole 24. The first pin 23 is located on the connecting rod 16, and the pin hole 24 is located on the long rod 15. When the connecting rod 16 is activated, the first pin 23 is slid out of the pin hole 24, allowing the movable rod 17 to slide relative to the long rod 15. Conversely, when the movable rod 17 is fixed, the connecting rod 16 is returned to its original position, allowing the first pin 23 to be inserted into the pin hole 24. At this time, the first pin 23 and the pin hole 24 are connected by an interference fit.

[0031] Specifically, the filter screen 14 includes a filter plate 26, and slide rails 27 are provided on both sides of the filter plate 26. The slide rails 27 slide relative to the long rod 15. A damping block 25 is provided on the other end of the long rod 15. The damping block 25 is used to fix and limit the slide rails 27 when they slide relative to the long rod 15. A fixed wedge-shaped block 28 is provided inside the slide rails 27. In summary, the movable pawl 19 rotates under the action of the rotating shaft 20. The movable pawl 19 is a combination of a gear 29 and a wedge block 30. The gear 29 meshes with the meshing teeth 18. When the movable rod 17 slides, the meshing teeth 18 drive the gear 29 to rotate, and the wedge block 30 rotates synchronously. The fixed wedge block 28 is fixed on the inner wall of the slide rail 27. The fixed wedge block 28 and the movable pawl 19 are on the same horizontal plane. When the filter screen 14 slides into the cleaning tank 1, one end face of the fixed wedge block 28 abuts against the inclined surface of the movable pawl 19. Under the action of the thrust, the fixed wedge block 28 pushes the movable pawl 19 to rotate, so that the filter screen 14 can be further pushed into the cleaning tank 1. When the filter screen 14 is fixed, the horizontal bottom surface of the movable claw 19 is tightly fitted with the other end face of the fixed wedge-shaped block 28. Due to the limitation of the reset stroke of the movable rod 17, the movable rod 17 is in a fixed state at this time. Therefore, the movable claw 19 is fixed and will not move due to the contact of the fixed wedge-shaped block 28. At the same time, in order to further improve the stability of the filter screen 14, the damping block 25 abuts against the long rod 15. The damping block 25 is made of rubber. Due to the elastic and plastic properties of rubber, the slide rail 27 can be fitted onto the long rod 15, and the slide rail 27 can also be prevented from coming off. Thus, the filter screen 14 is fixed.

[0032] Specifically, the cleaning assembly includes a motor 2 located on the top surface of the cleaning tank 1. A stirring rod 5 is mounted on the output end of the motor 2, with one end of the stirring rod 5 penetrating the top surface of the cleaning tank 1 and positioned within the first filtration zone 11. A water pipe 7 is located on one side of the motor 2, used to supply high-pressure water. A feed inlet 4 is provided on the top surface of the cleaning tank 1. The motor 2 is electrically connected to an external power source. When the raw material is added to the first filtration zone 11 through the feed inlet 4, the motor 2 starts and drives the stirring rod 5 to rotate. Simultaneously, the water pipe 7 continuously injects high-pressure water into the first filtration zone 11. During the stirring process of the stirring rod 5, the high-pressure water washes away impurities in the raw material, separating the impurities from the sand and gravel.

[0033] Specifically, a guide cover 3 is provided below the feed inlet 4. The guide cover 3 is located at the connection between the stirring rod 5 and the output shaft of the motor 2. The guide cover 3 is used to reduce the probability of the stirring rod 5 being hit by stones present in the raw material when the raw material is added into the first filtration zone 11, thereby increasing the service life of the stirring rod 5, and at the same time guiding the raw material to the bottom of the first filtration zone 11.

[0034] Specifically, a second filter zone 12 is provided at the bottom of the first filter zone 11. The first filter zone 11 and the second filter zone 12 are separated by the filter device 6. The bottom of the second filter zone 12 is provided with a discharge port 10. The side of the washing tank 1 is provided with several waste discharge ports 9. The tank wall of the washing tank 1 is provided with a slot, and a second pin 8 is provided in the slot. The second pin 8 is used to fix the filter device 6 in a horizontal state. During the washing process, the raw material in the first filter zone 11, after washing, obtains the required sand and gravel raw material, which flows through the filter screen 14 to the second filter zone 12 and is then discharged from the discharge port 10. Impurities in the raw material remain in the first filter zone 11. Furthermore, when it is necessary to discharge the above-mentioned impurities, the hatch of the waste discharge port 9 is opened, and the filter device 6 is flipped downwards. The impurities are then discharged from the filter device 6 through the waste discharge port 9. Furthermore, the waste discharge port 9 corresponds to the filter device 6.

[0035] Specifically, a vibration motor 13 is installed at the bottom of the cleaning tank 1. The output end of the vibration motor 13 abuts against the cleaning tank 1, and the vibration motor 13 is electrically connected to an external power source. During operation, the cleaning tank 1 is continuously subjected to the output of the vibration motor 13, causing the cleaning tank 1 to be in a vibrating state. This allows the filter plate 26 to vibrate continuously, preventing stones from clogging the filter screen 14 and improving the cleaning and filtration effect.

[0036] 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.
