[0029] The effect achieved by the entire embodiment 2 is that, under the action of the vibration support mechanism 2 and the continuous operation of the vibration device, two inclined plates 204 are fixedly connected to the inner surface wall of the fixed frame 203, and a vertical plate 205 is fixedly connected to the top of the inner wall of the fixed frame 203, wherein the outer wall of the vertical plate 205 is fixedly connected to one side of the outer wall of the two inclined plates 204, and they are connected using the principle of the stability of a triangle, so that the fixed frame 203 can ensure the stability of the entire device even when it is subjected to vibration for a long time, thereby enhancing the stability of the device and improving the safety of the device during operation.

[0030] Working principle: When in use, first pour the material to be screened into the top of the screen box 101, and then start the two driving motors 102 to drive the transmission shaft 103 fixedly installed at its output end to rotate, so that the eccentric block 104 fixedly sleeved on the outer wall of the transmission shaft 103 rotates, wherein the bottom of the screen box 101 is fixedly connected to the top of the connecting frame 201, and four round steel springs 202 are fixedly connected to the bottom of the connecting frame 201, and a fixing frame 203 is fixedly connected between the bottoms of the four round steel springs 202.
