The top of the support mechanism 1 is provided with a working hopper 2. The top of the working hopper 2 is provided with a screen 3 for screening sand and gravel. The bottom of the screen 3 is provided with a discharge plate 4. The discharge plate 4 is inclined and its front end extends through to the outside of the working hopper 2 for easy discharge. The top surface of the discharge plate 4 is connected to a vibration mechanism 5, and the bottom is provided with no less than two sets of vibration motors 6. The discharge efficiency of the discharge plate 4 can be improved by the vibration motors 6.

[0022] Please see Figure 1 This utility model provides a sand and gravel screening device for construction engineering.

A set of tilting plates 12 is hinged to the top front end of the base plate 11, and the top rear end is connected to the rear end of the tilting plate 12 through the electric push rod 13. The rear end of the tilting plate 12 can be lifted through the output end of the electric push rod 13, so that the tilting plate 12 tilts forward, which facilitates the discharge of the screen 3 and the discharge plate 4. A set of buffer seats 14 is provided at all four ends of the top surface of the tilting plate 12, and is connected to the working bucket 2 through the buffer seats 14, which can reduce the vibration of the working bucket 2 during operation.

[0023] Please see Figure 1-2This utility model provides a sand and gravel screening device for construction engineering. The vibration mechanism 5 includes a fixed base 51, a screw 52, ​​a crank handle 53, a movable base 54, an impact arm 55, a drive arm 56, and a reinforcing mechanism 57. A set of fixed bases 51 is provided at the top center of the discharge plate 4. A set of screws 52 is provided at the front center of the fixed base 51. The rear end of the screws 52 extends through to the rear end of the fixed base 51 and is connected to a set of crank handles 53. A set of movable bases 54 is provided at the top of the fixed base 51. The bottom end of the movable bases 54 is connected to the screws 52. A set of trapezoidal grooves is provided at the front center of the fixed base 51 corresponding to the position of the screws 52. A corresponding trapezoidal protrusion is provided at the bottom end of the movable base 54, which can improve the stability of the movable base 54 when moving. The middle end of the protrusion is provided with an inner groove corresponding to the screws 52. The threaded hole and the rotating crank handle 53 can drive the screw 52 to rotate, thereby adjusting the distance of the movable seat 54 outside the screw 52, ​​realizing the adjustment of the movement path of the impact arm 55, which is beneficial to adjusting the impact force of the impact arm 55 on the screen 3. The movable seat 54 is provided with a set of impact arms 55 at both the left and right ends. The left end of the left impact arm 55 is connected to a set of drive arms 56. The other end of the drive arm 56 extends through to the outside of the working bucket 2 and is connected to a set of motors 561. The bottom end of the drive arm 56 is connected to the left end movable groove 551 through a set of rollers. The rotation of the drive shaft of the motor 561 can drive the drive arm 56 to rotate, thereby driving the impact arm 55 to impact upward, so that the front end of the impact arm 55 can swing repeatedly. The right impact arm 55 is connected to a reinforcing mechanism 57.

[0024] Both sets of impact arms 55 have a set of movable grooves 551 at the middle of the side away from each other. The upper and lower ends of the right movable groove 551 are provided with a set of limiting grooves 552. Furthermore, the front ends of the impact arms 55 are thickened and set as arc shape to avoid damage to the screen 3. The two sets of impact arms 55 can rotate synchronously.

[0025] Please see Figure 2-3 This utility model provides a sand and gravel screening device for construction engineering. The reinforcing mechanism 57 includes a spring 571, a movable block 572, a rotating arm 573, and a roller 574. A set of springs 571 is connected to the front end of the right-end movable groove 551, and a set of movable blocks 572 is provided at the rear end of the springs 571. A set of rotating arms 573 is provided at the right end of the right-end impact arm 55, and a set of rollers 574 is connected to the bottom end of the rotating arm 573. The rollers 574 extend into the movable groove 551 and contact the rear end of the movable block 572. The upper and lower ends of the movable block 572 are provided with flanges corresponding to the limiting grooves 552, which can slide along the limiting grooves 552 in the movable groove 551. When the drive arm 56 drives the impact arm 55 to move downward, the spring 571 can be compressed through the movable block 572. When the drive arm 56 drives the impact arm 55 to swing upward, the spring 571 can release its elastic force, applying an additional force to the impact arm 55, making its upward swing speed faster, impacting the bottom end of the screen 3, and improving the filtration effect of the screen 3.

[0026] The working principle is as follows:

[0027] Before use, the crank handle 53 can be rotated to make the movable seat 54 drive the impact arm 55 to move along the screw 52, ​​and adjust the distance between it and the screen 3 to adjust the impact force on the screen 3.

[0028] In use, sand and gravel can be poured into screen 3, and then motor 561 can be started. The rotation of the drive shaft of motor 561 can drive two sets of impact arms 55 to swing up and down through drive arm 56. When drive arm 56 drives impact arm 55 to move downward, spring 571 can be compressed through movable block 572. When drive arm 56 drives impact arm 55 to swing upward, spring 571 can release its elasticity, applying an additional force to impact arm 55, making its upward swing speed faster and impacting the bottom of screen 3, thereby improving the filtering and screening effect of screen 3 on sand and gravel. Sand and gravel fall onto discharge plate 4 through screen 3 and are discharged out of working hopper 2 through the tilt angle of discharge plate 4, realizing the collection of sand and gravel. After the screening operation is completed, the rear end of tilting plate 12 can be lifted through the output end of electric push rod 13, so that tilting plate 12 tilts forward, making it easier to empty the remaining sand and gravel from screen 3 and discharge plate 4, facilitating subsequent cleaning operations.
