[0033] The lower filter assembly 47 includes a third push rod 471, which is arranged directly below the second cam 453. A lower filter screen 473 is provided at the bottom end of the third push rod 471. A fourth push rod 472 is provided at the top of the lower filter screen 473. The fourth push rod 472 is arranged directly below the first cam 443. The lower filter screen 473 passes through four second slide rods 474.

[0034] During use, the staff first starts the motor 411, and the output end of the motor 411 drives the worm wheel 414 to rotate through the worm gear shaft 413, and the worm wheel 414 drives the meshing worm 415 to rotate, and the worm 415 drives the two first bevel gears 417 fixedly installed at the upper and lower ends to rotate, and the first bevel gear 417 at the upper end drives the second bevel gear 421 to rotate, and the second bevel gear 421 drives the third bevel gear 423 to rotate through the first rotating shaft 422, and drives the two pulleys and belts inside the first belt transmission assembly 441 to rotate, and one of the pulleys drives the third rotating shaft 442 to rotate. The third rotating shaft 442 drives the first cam 443 to rotate, and the first bevel gear 417 at the lower end drives the fourth bevel gear 431 to rotate. The fourth bevel gear 431 drives the two pulleys and belts inside the second belt transmission assembly 451 to rotate through the second rotating shaft 432. One of the pulleys drives the fourth rotating shaft 452 to rotate, and the fourth rotating shaft 452 drives the second cam 453 to rotate. The rotation of the first cam 443 will intermittently push the second push rod 462 to move upward and the fourth push rod 472 to move downward.

Since the first push rod 461 and the second push rod 462 are fixedly connected to the bottom of the upper filter screen 463, the upward movement of the first push rod 461 and the second push rod 462 will move the upper filter screen 463 upward along the four first slide bars 464, thereby squeezing the four first springs 465 to generate tension. Since it is an intermittent push movement, the tension of the first springs 465 will restore the upper filter screen 463 to its original position, thereby achieving a vibration effect on the upper filter screen 463. Since the third push rod 471 and the fourth push rod 472 are fixedly connected to the lower At the top of the filter screen 473, the downward movement of the third push rod 471 and the fourth push rod 472 will move the lower filter screen 473 downward along the four second sliding rods 474, thereby squeezing the four second springs 475 to generate tension. Due to the intermittent pushing movement, the tension of the second springs 475 will restore the lower filter screen 473 to its original position, thereby achieving the vibration effect of the lower filter screen 473, and ultimately achieving the purpose of screening sand twice, so that impurities are filtered more completely without affecting the subsequent use of sand. At the same time, the filter screen will be vibrated, thereby avoiding the problem of filter screen blockage and improving work efficiency.
