Because the lower end of the inner cylinder 20 connected with the screw 14 is fixed with the vibrating screen base 1 through the rotating pin 4, the left lifting assembly 6 and the right lifting assembly 8 can rotate back and forth at a certain angle, therefore, the lead screw 19 drives the speed reducer 10, the outer cylinder 21 and the connected components to move upwards, so that the spring seat 22 drives the damping spring 5 and the front end of the screen box 2 to move upwards, the inclination angle of the screen box 2 is increased, when the proper inclination angle is reached, the power supply of the motor 11 is cut off, the motor 11 stops working, and the inclination angle of the screen box 2 is locked due to the reverse self-locking function of the speed reducer 10. When the tilt angle is adjusted to the maximum, the touch plate 16 contacts the down stroke switch 18, and the motor is stopped. Conversely, when the starter motor 11 rotates in the reverse direction, the inclination of the sieve box 2 decreases until the touch plate 16 contacts the upper limit switch 15. This allows for electrical adjustment of the inclination of the sieve box.
