Before use, sand and gravel need to be screened to remove impurities and classify them according to particle size. Usually, construction material screening devices are used. Existing construction material screening devices usually screen sand and gravel through vibrating screens. However, because sand and gravel are easily mixed with wet mud, it is difficult for the screen to separate the wet mud from the sand and gravel during screening, which affects the screening efficiency and quality of sand and gravel.
[0003] Therefore, a material screening device for construction has now been developed that can separate wet mud mixed in sand and gravel, thus avoiding affecting the screening efficiency and quality of sand and gravel. Utility Model Content
[0004] To overcome the shortcomings of existing construction material screening devices, which have difficulty separating wet mud from sand and gravel during screening, thus affecting the screening efficiency and quality, this utility model provides a construction material screening device that can separate wet mud mixed in with sand and gravel, thereby avoiding affecting the screening efficiency and quality.
[0005] Technical Solution: A material screening device for construction includes a water tank, a mounting frame, springs, a drive assembly, a slider, guide columns, an electric push rod, a material bucket, a first permeable net, a support column, a linear motor, an eccentric hammer, and auxiliary components.

Guide columns are connected to the lower sides of both the front and rear parts of the mounting frame. A slider is slidably connected between the guide columns. An electric push rod is connected to the lower side of the slider. A material bucket is connected to the telescopic end of the electric push rod. The first permeable net is threadedly connected to the lower side of the material bucket. A support column is connected to the rear side of the middle of the water tank. A linear motor is connected to the upper part of the support column. An eccentric hammer is connected to the output shaft of the linear motor. The eccentric hammer is in a pressing fit with the mounting frame. Auxiliary components for assisting material screening are provided on the water tank.
[0006] In a preferred embodiment of this utility model, the driving assembly includes a driving motor and a driving screw. The driving motor is connected to the left side of the mounting bracket, and the driving screw is connected to the output shaft of the driving motor. The driving screw is rotatably connected to the mounting bracket, and the slider is threadedly connected to the driving screw.
[0007] In a preferred embodiment of this utility model, a filter screen is provided on the lower side of the material barrel.
[0008] In a preferred embodiment of this utility model, the auxiliary components include a collection box, a second permeable net, a water pump, and a nozzle.

Detailed Implementation
[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0019] A material screening device for construction, such as Figures 1-5As shown, the assembly includes a water tank 1, a mounting frame 2, springs 3, a drive assembly 4, a slider 5, guide posts 6, an electric push rod 7, a material bucket 8, a first permeable net 9, a support column 10, a linear motor 11, an eccentric hammer 12, and auxiliary components. The mounting frame 2 is slidably connected to the upper side of the water tank 1. Eight springs 3 connect the mounting frame 2 to the water tank 1. The drive assembly 4 is mounted on the mounting frame 2. Guide posts 6 are connected to the lower sides of both the front and rear parts of the mounting frame 2. Slider 5 is slidably connected between the guide posts 6. The drive assembly 4 includes a drive motor and a drive screw. The drive motor is connected to the left side of the mounting frame 2. The drive screw is connected to the output shaft of the drive motor and is rotatably connected to the mounting frame 2. The slider 5 is threadedly connected to the drive screw. An electric push rod 7 is connected to the lower side of the slider 5. The material bucket 8 is connected to the telescopic end of the electric push rod 7. A filter screen is provided on the lower side of the material bucket 8 to facilitate the separation of wet mud. A first permeable net 9 is threadedly connected to the lower side of the material bucket 8. A support column 10 is connected to the rear side of the middle of the water tank 1. A linear motor 11 is connected to the upper part of the support column 10. An eccentric hammer 12 is connected to the output shaft of the linear motor 11. The eccentric hammer 12 is squeezed and fitted with the mounting frame 2. An auxiliary component is provided on the water tank 1. The auxiliary component includes a collection box 13, a second permeable net 14, a water pump 15, and a nozzle 16. The collection box 13 is slidably detachably connected to the right side of the water tank 1. A handle is provided on the front side of the collection box 13 for easy removal. The second permeable net 14 is connected inside the collection box 13. The water pump 15 is connected to the right side of the water tank 1.

A valve is rotatably provided on the nozzle 16 for easy control of opening and closing.
[0020] When using this invention, first place the water tank 1 in the construction material screening area, pour water into the water tank, and then pour the sand and gravel to be screened into the material bucket 8. Next, start the electric push rod 7 to push the material bucket 8 downwards, immersing the material bucket 8 and the first permeable mesh 9 in the water. Then, start the linear motor 11 to drive the eccentric hammer 12 to rotate, causing the eccentric hammer 12 to press against the mounting frame 2. Under the force of the spring 3, the mounting frame 2 moves up and down repeatedly, causing the material bucket 8 and the first permeable mesh 9 to move up and down in the water. At this time, the wet mud in the material bucket 8 is dispersed through the lower filter screen and the first permeable mesh 9, thus separating the wet mud mixed in the sand and gravel, avoiding affecting the screening efficiency and quality. After the wet mud is removed, move the material bucket 8 upwards to reset. Remove the first permeable net 9, then start the drive motor in the drive assembly 4 to rotate the drive screw, causing the slider 5 to move to the right along the guide column 6, moving the material bucket 8 above the collection box 13. Then start the electric push rod 7 to push the material bucket 8 downward, so that the material bucket 8 is below the nozzle 16. Then start the linear motor 11 to make the mounting frame 2 drive the material bucket 8 to vibrate, screening the sand and gravel in the material bucket 8. The sand and gravel that meet the requirements fall through the filter screen at the bottom of the material bucket 8 onto the second permeable net 14. During screening, turn on the nozzle 16 and start the water pump 15 to draw water from the water pool 1 into the nozzle 16, so that the nozzle 16 sprays water into the material bucket 8 to assist in screening the sand and gravel. After the water is sprayed out, it flows back to the water tank through the second permeable net 14 and the collection box 13.
