Vibrating screen

Abstract

The invention relates to a vibrating screen. The vibrating screen comprises a foundation support, a horizontal vibration attenuation mechanism, a vertical supporting mechanism, a horizontal guide rail, a bracket and a motor, wherein the foundation support is provided with a horizontal supporting part and vertical supporting parts, and the vertical supporting parts are arranged on two ends of the horizontal supporting part; the horizontal vibration attenuation mechanism is connected with the vertical supporting parts of the foundation support; the vertical supporting mechanism is connected with the horizontal supporting part of the foundation support; the horizontal guide rail is respectively connected with the vertical supporting parts and the horizontal supporting part of the foundation support through the horizontal vibration attenuation mechanism and the vertical supporting mechanism; the bracket is used for fixing a screen assembly, and the bracket can be movably fixed on the horizontal guide rail through a slide block; the motor is installed on the foundation support, and a rotating shaft of the motor is connected with the slide block through a crank linkage mechanism. According to the vibrating screen of the invention, a spring is uniformly stressed, the service life is prolonged, and the vibration amplitude of the screen assembly can be conveniently adjusted.

Description

technical field [0001] The invention relates to a vibrating screen. Background technique [0002] In the process of making solid granular or powdery materials, vibrating screens are often used. Commonly used vibrating screens include structural components such as screen frames, screen meshes, springs connected to the screen frames, and excitation motors. The screen is vibrated by exciting the motor, so that the small particles pass through the screen and leak down, and the large particles are blocked on the screen. So as to achieve the purpose of screening and grading materials. Generally, a rotary vibrating screen is used for operation, and a spring is used for shock absorption. The vibration effect is not ideal, and the service life of the spring is short. [0003] Solving the problems of uneven stress on the spring and poor vibration effect of the screen has always been a subject of continuous exploration by those skilled in the art. In order to solve the above proble...

Problems solved by technology

Generally, the rotary vibrating screen is used for operation, and the spring is used for shock absorption, the vibration effect is not ideal, and the service life of the spring is short

[0003] Solving the problems of uneven spring force and poor vibration effect of the screen has always been a subject of continuous exploration by relevant technical personnel in the field

One of the measures is to increase the vibration intensity of the vibrating screen, but this treatment method is often easily limited by the rigidity of the screen box, and the dispersion, stratification and interlayer movement of materials on the screen surface lack sufficient power
