Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotary vibration screens, and more specifically to a rotary vibration screen. Background Art
[0002] The rotary vibrating screen is a high-precision fine powder screening machine. It uses an upright motor as the excitation source. Eccentric weights are installed at the upper and lower ends of the motor to convert the motor's rotational motion into horizontal, vertical and inclined three-dimensional motion, and then transmit this motion to the screen surface, so that the material makes an outward expansion involute motion on the screen surface. Therefore, the material placed on the screen moves in a diffused state. When the staff adds material, if the material is at the edge of the screen, it is easy to cause the material to be discharged from the side discharge port without sufficient vibration screening, which can easily lead to a decrease in screening accuracy. Therefore, it is urgent to design a rotary vibrating screen. Utility Model Content
