Vibrating screen provided with cam segment

Abstract

The invention discloses a vibrating screen provided with a cam segment. The vibrating screen comprises a frame, connecting rods, a screen, rollers, guide rods and a push rod, wherein the rollers are connected to the frame; a sliding chute is formed in the frame; the screen is connected with the sliding chute in a sliding way; one end of each connecting rod is connected to the rollers; the other ends of the connecting rods are hinged to the side face of the screen; the guide rods are connected to the screen; the push rod is fixed on the frame; the cam segment is arranged on the push rod; the cam segment is pressed against the edge of the lower surface of the screen; the trend of the sliding chute is matched with the wire diameter of the cam segment on the push rod; the guide rods of the screen are connected into the sliding chute in a sliding way; support rods are arranged along the radial directions of the rollers; the support rods are provided with a plurality of mounting holes; the connecting rods are hinged to the rollers through the mounting holes. The screen moves in a fixed direction through the connecting rods and the cam segment on the push rod, the screen moves in the horizontal direction through the connecting rods, and the screen moves in the vertical direction through the cam segment on the push rod, so that more moving ways are provided for the screen, the screen can vibrate leftwards, rightwards, upwards and downwards, and materials are in full contact with the screen.

Description

technical field [0001] The invention belongs to the technical field of movable sieves. Background technique [0002] The vibrating screen is a device that makes materials smaller than the screen hole fall from the screen through the reciprocating motion of the screen, and is widely used in the screening of materials. [0003] The existing vibrating screen structure includes a frame, connecting rods, screen mesh and rollers connected to the frame. The frame is provided with a horizontal linear chute. On the side of the net, the screen moves along a plane with the direction of the chute. But such a structure can only make the screen cloth move on one plane, but cannot make the screen cloth move along the third direction. While the screen moves in a curved line, the screening effect of the materials on it is better. When the screen moves in a curved line, it can not only vibrate left and right, but also move up and down, so that the material can fully contact with the screen...
