The design concept of the whole device is described in conjunction with fig. 8 and 9 as follows:
because the conventional screening device vibrates vertically, as shown in fig. 8, G represents the gravity of the vibrating object (G can be understood as the gravity of the upper housing 2 in combination with the device, and it is assumed that the upper housing 2 vibrates vertically), and F represents the upward lifting force; when F is larger than G, the requirement of lifting and vibrating the vibrating object can be met;
the vibration mode adopted by the device is oblique sliding, as shown in fig. 9, wherein F1 and F2 are respectively expressed as F decomposition acting forces in two axial directions (because the friction force between the roller 4 and the guide rail 3 is small and can be ignored), specifically, F1 is a pulling force in the direction of the guide rail 3, and F2 is a supporting force of the guide rail 3;
it can be seen that the magnitude of the force F1 is significantly less than F, so that the device can provide energy savings, and in particular, reduce the load on the drive unit 5; if the upper housing 2 is simply slid back and forth in the horizontal direction, although F1 is smaller and more labor-saving, the upper housing 2 lacks the process of up-and-down movement, and the vibrating screening effect is not good;
therefore, the device can simultaneously vibrate up and down and left and right, and the screening effect is good.
