Description

Technical Field

[0001] The utility model relates to the technical field of stone screening, and more specifically, to a stone screening device for construction materials. Background Art

[0002] In highway construction, gravel screeners are equipment used to screen and separate gravel, usually to screen out gravel that meets specification requirements for use in roadbed, pavement or other construction projects. Existing gravel screeners are difficult to screen gravel quickly, which reduces the screening efficiency and thus affects the progress of construction.

[0003] The utility model with announcement number CN215784858U discloses a gravel screener for highway construction. The utility model drives the eccentric wheel to rotate through a rotating shaft, and then drives the screening frame to swing up and down, so that the screen can quickly screen the gravel. The frequency of the shaking of the screening frame is increased by the elastic force of the spring, thereby further improving the efficiency of the screen in screening the gravel, and accelerating the speed of gravel discharge through the discharging hopper, thereby solving the problem that the existing gravel screener is difficult to quickly screen the gravel, improving the screening efficiency, and thus ensuring the progress of construction.

[0004] During the use of the above-mentioned gravel screener, the water pump draws water from the water tank into the outlet pipe and sprays water mist through the atomizing nozzle to suppress the dust generated when screening the gravel. However, it is not convenient to remove the moisture in the gravel. The presence of moisture in the gravel will affect the slurry ratio of the concrete, reduce the strength and durability of the concrete, and thus affect the service life of the road.

The utility model drives the inner frame to move up and down reciprocatingly through the convex block, two filters screen the stones, the water pump works to extract water in the water tank and injects it into the nozzle through the first hose, and finally discharges the water downward through the nozzle to clean the stones and reduce dust. At the same time, the water flows back to the water tank through the water pipe, the hair dryer works to generate wind, the wind enters the nozzle through the second hose, and finally discharges the wind downward through the nozzle to air dry the stones. The operation is simple and convenient to remove moisture in the stones.

[0017] 2. The utility model can drive the baffle to move horizontally to the left by rotating the screw rod in the forward direction.

The cleaning and drying component 3 includes a water pump 301, a first hose 302, a nozzle 303, a hair dryer 304 and a second hose 305. Springs 6 are movably provided inside the four telescopic rods 7, and the top and bottom ends of the four springs 6 are fixedly connected to the inner frame 2 and the outer frame 1 respectively.

[0028] Furthermore, the water pump 301 is fixedly installed on the front side of the water tank 5, one end of the first hose 302 is fixedly connected to the output end of the water pump 301, and the other end of the first hose 302 is fixedly connected to the nozzle 303, and the nozzle 303 is fixedly installed inside the inner frame 2, one end of the second hose 305 is fixedly connected to the nozzle 303, and the other end of the second hose 305 is fixedly connected to the output end of the hair dryer 304, and the hair dryer 304 is fixedly installed on one side of the outer frame 1, and a first valve 306 is fixedly installed on the first hose 302, and a second valve 307 is fixedly installed on the second hose 305.

[0029] Furthermore, three material guide plates 13 are fixedly connected to one side of the inner frame 2, and a discharge hopper 8 is fixedly provided on one side of the three material guide plates 13, and the three discharge hoppers 8 are fixedly connected to the other side of the outer frame 1. A shielding assembly 4 is provided on the inner frame 2, and the shielding assembly 4 includes two side frames 401, a screw rod 402, a baffle 403 and a limit rod 404.

[0031] The method of using this embodiment is:

[0032] When in use, the stones are poured into the inner frame 2, and then the motor 10 is started. The motor 10 drives the rotating shaft 11 to rotate, thereby driving the protrusion 12 to rotate, and the inner frame 2 is driven to move up and down reciprocatingly through the protrusion 12. At the same time, the inner frame 2 drives the four telescopic rods 7 to stretch to prevent the inner frame 2 from deflecting when moving vertically, and the stones in the inner frame 2 are shaken. The two filter screens 9 screen the stones. At the same time, the water pump 301 is started. The water pump 301 draws water from the water tank 5 and injects it into the nozzle 303 through the first hose 302. Finally, the water is discharged downward through the nozzle 303 to clean the stones and reduce dust. At the same time, the water passes through the water pipe 14 The water flows back into the water tank 5, and the hair dryer 304 is started after screening. The hair dryer 304 generates wind when it works. The wind enters the nozzle 303 through the second hose 305, and is finally discharged downward through the nozzle 303 to dry the stones. The operation is simple and convenient for removing moisture from the stones. At the same time, the upward movement of the inner frame 2 will drive the four springs 6 to stretch. When the protrusion 12 moves away from the inner frame 2, the four springs 6 rebound and drive the inner frame 2 to move downward, closing the first valve 306 so that the wind cannot enter the water pump 301 through the first hose 302, and closing the second valve 307 so that water cannot enter the hair dryer 304 through the second hose 305.
