Abstract

The utility model discloses a sand screening machine, comprising a motor, a retarder, a support arm, a connecting rod, a link span, a screen, a conveyer belt, a machine frame and a pulley. The screen of the sand screening machine makes reciprocal movement, which is driven by the motor and the retarder. The retarder is connected with the support arm and the connecting rod is axially connected with the support arm and the link span. The link span is connected with the screen frame. The lower side of the machine frame is connected with a hopper the open of the hopper is corresponding to theconveyer belt, the side of the machine frame is provided with a sand stone lower hopper. Two pulleys in one group are vertically connected. The convex surface of the upper pulley is arranged on the cross beam on the side of the machine frame, and the lower pulley is connected with the screen frame. The pulley with the cross beam on the sides of the machine frame as the orbit drives the screen to move reciprocally. The utility model can be completely in place of artificial screening, having advantages of small labour intensity, high working efficiency, convenient change of sand screen simple and practical structure and low cost; the sand screen can be changed anytime according to the need of engineering.

Description

Sand sieving machine

Technical field:

The utility model relates to the sand sieving machine that a kind of engineering construction is used.

Background technology:

At present, architectural engineering all is that artificial scene sieves by hand with sand, and method is original, and labour intensity is big, inefficiency.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of sand sieving machine at the problems referred to above, reduces labour intensity, increases work efficiency.

The technical solution of the utility model is: the screen cloth of sand sieving machine drives reciprocating on frame by motor, decelerator, decelerator connects support arm, and connecting rod is connected with support arm, link axle, and link is connected with the screen cloth frame; Connect hopper below the frame, the corresponding conveyer belt of hopper mouth, there is rough sand stone hopper the side; Two on pulley is one group and vertically connects, above the convex surface of pulley be placed on the crossbeam of frame both sides, following pulley is connected with the screen cloth frame, pulley is a track with the crossbeam of frame side, it is reciprocating on frame to drive screen cloth.

During work, by the motor-driven decelerator, the connecting rod that is connected with decelerator promotes screen cloth, screen cloth is under the drive of pulley, reciprocating on frame, the fine sand that sifts out is directly delivered to mixer from the hopper of frame bottom by conveyer belt, and rough sand stone is told by the rough sand hopper of frame side.

Screen cloth can be made into all size, changes at any time as required, only needs during replacing connecting rod is unloaded, and changes required screen cloth and gets final product.

The utlity model has following advantage and good effect:

1. can replace artificial sieve husky fully, labour intensity is little, high efficiency;

2. can change husky net at any time according to requirement of engineering, it is convenient that husky net is changed;

3. simple in structure, practical, cost of manufacture is low.
