Problems solved by technology

The working part of the vibrating screen is fixed, and the materials are screened by sliding along the working surface. This structure is simple and easy to manufacture, and the materials can be directly unloaded on the screen surface, but the productivity is low and the screening efficiency is low, generally only 50 -60%, it is also easy to block the screen hole, control the material entering the screen surface, the speed should not be too fast, secondly, the vibrating screen vibrates violently during the working project, the general base is directly fixed on the ground, sometimes due to the uneven ground, resulting in Loud noise and poor screening effect

Embodiment Construction

[0015] like figure 1 As shown, the vibrating screen of the present invention includes a base 1, a sieve body 2, a coil spring 4 and a vibrating motor 3, the screen body 2 is fixed on the base 1 by the coil spring 4, the base 1 is connected with the base lifting and stabilizing device, and the base lifting is stable The device includes a lifting platform 5 and a fixed support base 6 connected with the lifting platform 5, so that the base 1 can be stably fixed on the ground, and the height of the sieve body 2 can also be adjusted as required. There are 3-6 layers of screens 7, the inclination angle of the screen body 2 and the screen 7 is 30-60°, the screen body 2 and the screen 7 are set at an inclination, plus the gravity of the material, better screening, each layer The tail end of the screen 7 is connected with a collection port 8, and a material conveying device is installed on the top of the screen body 2. The material conveying device is a box 10 with an auger 9 inside, a...

Abstract

The invention discloses an oscillation screen. The oscillation screen comprises a base, a screen body, an elastic element and an oscillation motor, wherein the screen body is fixed on the base by virtue of the elastic element; the base is connected with a base lift stabilizing device; the screen body is tilted to the ground; a plurality of layers of screens are fixed in the screen body slantways, and an aggregating port is connected to the tail end of each layer of the screen; a material conveying device is arranged on the upper part of the screen body; and a speed controller is arranged on the material conveying device. The oscillation screen has the advantages of good screening effect and small screening noise.

Description

technical field [0001] The invention relates to a vibrating screen. Background technique [0002] The vibrating screen is mainly composed of a screen box, a vibrator, a supporting device and a motor. The motor drives the main shaft of the vibrator to rotate through the V-belt. Due to the centrifugal inertial force of the unbalanced weight on the vibrator, the screen box vibrates. The working part of the vibrating screen is fixed, and the materials are screened by sliding along the working surface. This structure is simple and easy to manufacture, and the materials can be directly unloaded on the screen surface, but the productivity is low and the screening efficiency is low, generally only 50 -60%, it is also easy to block the screen hole, control the material entering the screen surface, the speed should not be too fast, secondly, the vibrating screen vibrates violently during the working project, the general base is directly fixed on the ground, sometimes due to the uneven...
