Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a table-type vibrating screen. Background Art

[0002] Vibrating screen refers to a screen that filters and screens materials on the surface of the screen through vibration. It is often used to screen sand and gravel of different sizes in mining.

[0003] For example, the Chinese patent application number 202321846364.2 is a crushing and processing vibrating screen. When it is necessary to prevent andalusite from splashing out, the patent can start the motor, so that the motor drives the threaded rod to move, and then drives the support rod to move. Since the connecting plate and the rectangular block are fixedly connected, and the round rod and the support rod are slidably connected, and the connecting rod connects the support rods at both ends, the support rod moves, driving the folding plate to move. When the folding plate is fully unfolded, it can prevent andalusite from splashing out due to vibration, thereby achieving the effect of preventing andalusite from splashing out. When the vibrating screen body operates on andalusite, the vibrating screen body may splash and splash the andalusite to the outside when it is working. Since the vibrating screen body is high, the splashing falling rocks may injure workers.

[0004] However, the above patent can only screen the sand and gravel once during vibration screening, resulting in insufficient screening of the sand and gravel, which makes it easy for some fine gravel to mix into the sand, thereby seriously affecting the screening quality of the sand and gravel.
