A multi-directional shaking sand screening device

Abstract

The invention discloses a multi-directional rocking sand screening device, which comprises a base, a screening frame and a moving block; vertical plates are symmetrically fixed on the left and right sides of the top of the base, and support plates are fixed between the vertical plates on both sides; The screening frame is arranged above the support plate, and the bottom of the screening frame is connected to the support plate through connecting springs. The bottom of the screening frame is equidistantly connected with a plurality of vertically arranged sliding rods, and the lower ends of the sliding rods pass through the supporting plate. The bottom of the sliding rod is equipped with rollers; the moving block is arranged between the base and the support plate, the top of the moving block is provided with a curved surface, and the center of the bottom of the moving block is fixed with a movable frame. The movable frame is Front and back opening design, the inner cavity of the movable frame is symmetrically provided with straight tooth surfaces on the upper and lower sides, and an incomplete gear is provided to extend into the movable frame and mesh with the straight tooth surfaces on both sides. The present invention can effectively improve the screening efficiency by enhancing the irregular shaking of the screening frame.

Description

technical field [0001] The invention relates to a screening device, in particular to a multi-directional shaking sand screening device. Background technique [0002] In building construction, fine sand is one of the most important building materials. However, the raw materials of sand are relatively rough and need to be filtered and screened. We mainly rely on sand screening machines to separate them from some sundries. This is very widely used. of sand. Sand screening machine, also known as Delong dry land sand screening ship, is suitable for sand and stone separation equipment on rivers, reservoirs, coal yards and construction sites. Very commonly used mechanical equipment is widely used in many fields, and its role in production and construction is becoming more and more obvious. [0003] Most of the existing sand screening devices have the problem of low efficiency. The reason is that the relative movement between the sand and the sieve plate is not very violent, and a...

Problems solved by technology

[0003] Most of the existing sand screening devices have the problem of low efficiency. The reason is that the relative movement between the sand and the sieve plate is not very violent, and a relatively direct way to strengthen this relative movement is to strengthen the insufficiency of the sieve plate. Regular movement, so the present invention proposes a multi-directional shaking sand screening device
