Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative work, all belong to the protection scope of the present invention.

Referring to fig. 1 to 5, the present invention provides a technical solution: a vibration shakeout machine convenient for replacing a screen comprises a screen 1, a grid 2 is inserted in the screen 1, a grid bayonet 3 is inserted at the top end of the grid 2, a bayonet spring 4 is placed at the tail part of the grid bayonet 3, a dovetail block 5 is fixedly connected at the lower end of the screen 1, the dovetail block 5 is inserted in a dovetail groove 61, dovetail 61 sets up in

bar piece

6, 6 tops of bar piece are pegged graft and are had fixed fixture block 7, fixture block spring 8 has been placed to fixed fixture block 7 lower extreme, fixture block spring 8 lower extreme is placed in spring hole 9, it has roller pivot 10 to peg graft in the dovetail 61, fixedly connected with roller 11 on the roller pivot 10, reference column 12 has been placed to 6 tail ends of bar piece, reference column spring 13 has been placed to reference column 12 lower extreme, terminal surface and damping spring 14 upper end fixed connection under the bar piece 6, damping spring 14 lower extreme fixed connection is on base 15, terminal surface has placed storage sand silo 16 under the screen cloth 1.

Grid bayonet lock 3 is L shape, and grid bayonet lock 3 and bayonet lock spring 4 all have four.
