Problems solved by technology

The excitation effect of the screen surface in this structure is largely related to the elastic parameters of the spring components. Since the elastic parameters of the spring components have been set during installation, if you want to change the excitation effect curve of the screen surface, you need to stop the machine Make adjustments, not easy to use

Abstract

The invention discloses an improved vibrating screen device comprising a rack and a screen plate. The top of the rack is connected with the screen plate through a plurality of pneumatic connecting rods; each pneumatic connecting rod comprises a cylinder body and a piston which are in inserted connection, wherein the side wall of the cylinder body is provided with a plurality of air holes arrangedaxially, and each air hole is connected to an air source through a two-position three-way valve; a flow path shaped like a circular truncated cone is arranged in each air hole, a matched plug is movably inserted in each flow path shaped like the circular truncated cone, the top and bottom of each plug are connected with convex portions through connecting rods, the convex portions are located in the cylinder body, the pistons are in extrusion contact with the corresponding convex portions when passing through the air holes, and the connecting rods and the plugs are connected by the springs. Theinvention can overcome shortcomings in the prior art, and the excitation effect of the screen surface can be flexibly adjusted without stopping the device.

Description

technical field [0001] The invention relates to an automatic sorting device, in particular to an improved vibrating screen device. Background technique [0002] The vibrating screen uses the vibration of the screen surface to screen the granular materials, and is widely used in the field of industrial and agricultural production. Existing vibrating screens usually use a motor to provide power for the vibration of the screen surface, and the screen surface achieves a reciprocating vibration effect through a spring assembly. The excitation effect of the screen surface in this structure is largely related to the elastic parameters of the spring components. Since the elastic parameters of the spring components have been set when the machine is installed, if you want to change the excitation effect curve of the screen surface, you need to stop the machine Adjustment is not easy to use. Contents of the invention [0003] The technical problem to be solved by the present invent...
