Description

Technical Field

[0001] The utility model belongs to the technical field of screening devices, and more specifically, particularly relates to a vibrating screening device. Background Art

[0002] The vibrating screening device works by utilizing the reciprocating vibration generated by the excitation of the vibrator. Through the transmission of the vibration, the screen follows its vibration, and then the material on the screen also vibrates. In the continuous vibration process, the coarser material is retained on the screen, while the finer material passes through the screen and is screened out, thereby achieving the purpose of screening materials of different particle sizes. It is generally used to classify materials of different sizes.

[0003] Based on the above, the inventors have found the following problems: most of the current vibrating screening devices require manual pouring of the material to be screened into the screen plate. The material will accumulate on the screen plate and needs to be vibrated by a vibrating motor for a long time to disperse the material, which in turn increases the screening time of the material and reduces the material screening efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a vibrating screening device is provided to achieve a more practical purpose. Utility Model Content
