Vibrating screen machine with punching screen plate structure for materials with different lengths

Abstract

The invention discloses a vibrating screen machine with a punching screen plate structure for materials with different lengths. The vibrating screen machine comprises a rack and a screen bed, whereina plurality of damping bases are arranged at the bottom of the rack; the screen bed is arranged on the rack; a screen plate is arranged in the screen bed; a long material outlet is formed in the frontend of the screen plate; a short material outlet is formed in the front end of the lower portion of the screen plate; a plurality of dense isosceles trapezoid punched holes are formed in the screen plate; isosceles trapezoid baffles inclining downwards are arranged in the punched holes; the lower bottom edges of the baffles are welded to the lower bottom edges of the isosceles trapezoid punched holes; and the upper bottom edges of the baffles are suspended below the punched holes. The vibrating screen machine with the punching screen plate structure for the materials with the different lengths is simple and practical, and screen holes are not prone to being blocked in the material screening process; and meanwhile, the materials with the same or slightly different sections but different lengths can be effectively screened without complex equipment, the screening cost is low, the screening efficiency is high, the screening effect is good, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of vibrating sieve machines, in particular to a vibrating sieve machine with a perforated sieve plate structure for materials of different lengths. Background technique [0002] The vibrating sieve machine is used in conjunction with the test sieve to analyze the particle size of the material. Instead of the manual sieving machine, the vibrating sieve machine can effectively separate the impurities in the material so that the staff can analyze them. [0003] Although the vibrating sieve machine can effectively separate impurities through vibration, and the effect is obvious, the sieve holes of the vibrating sieve machines on the market are generally simple square or round holes, which are easy to cause sieve holes during the material screening process. Especially for materials with the same or little difference in cross-section but different lengths, such as shallots, etc., generally require complex equipmen...
