[0028] The working principle and use process of the utility model are as follows: when in use, the power of the vibration motor 12 and the fan 4 is turned on, at which time the screening box 1 and the screening pipe 24 both vibrate vertically, and then the calcium carbonate to be screened (hereinafter referred to as the material) is put into the interior of the screening pipe 24, at which time the material is filtered through the filter screen 22, and the screening pipe 24 and the filter screen 22 vibrate horizontally and vertically under the vibration action of the vibration motor 12 and the first elastic connecting member 21, thereby realizing rapid and sufficient screening of the material;

[0029] Through the vibration of the screening tube 24, the adjustable knocking plate 25 is vibrated vertically under the vibration of the second elastic connecting member 26, so that the adjustable knocking plate 25 is reciprocated vertically and horizontally, and the movement of the adjustable knocking plate 25 is used to quickly crush the retained materials, thereby further improving the crushing effect of the device on the materials, and the vertical reciprocating movement of the adjustable knocking plate 25 is used to knock and clean the filter screen 22, thereby preventing the filter screen 22 from being blocked during use;

[0030] The materials passing through the filter screen 22 fall down after being guided by the first guide plate 3 and the second guide plate 5. During the falling process, the falling materials are screened by the fan 4. The heavy materials fall directly, while the light materials change their falling paths under the action of the wind, thereby realizing further classification and screening of the materials. The screened materials fall into the storage box 8 after being guided by the lower hopper 9 for storage. When the storage box 8 needs to be maintained, the user can directly pull out the storage box 8 for maintenance.

[0031] Therefore, through the mutual cooperation of multiple structures, the materials can be screened quickly and fully, and through the mutual cooperation of multiple structures, the screening device can automatically crush the retained materials during the screening process, thereby improving the screening efficiency of the device. Secondly, the utility model has a warning function, which makes the function of the screening device more abundant. In addition, the utility model has a simple structure, is easy to use, and is worthy of promotion and use.
