Linear vibrating screen with adjustable amplitude and vibration direction angle

Abstract

The invention discloses a linear vibrating screen with the adjustable amplitude and vibration direction angle. The linear vibrating screen comprises a main screen body, a screen face, a machine frame,a rubber spring, a spring support and vibration motors, wherein the main screen body is composed of side plates, a reinforcing pipe beam, a supporting cross beam, a discharging port, motor supports,a rear baffle and a main beam. The main beam, the reinforcing pipe beam, the supporting cross beam, the discharging port, the rear baffle, the motor support and the spring support are fixed to the side plates through bolts, the two vibration motors are installed on the motor supports on the two sides respectively, the main screen body is connected with the machine frame through the rubber spring,and the machine frame is fixed to the ground through foundation bolts. The amplitude of the main screen body can be changed by changing the sizes of the rubber spring, the included angle between the vibration direction and the screen face can be changed by changing the fixing positions of the bolts on the vibration motors and the motor supports, adjustment of the amplitude and the vibration direction angle is achieved, the vibration screen can adapt to different working conditions, the good screening effect is guaranteed, operation is easy, and efficient reliability is achieved.

Description

technical field [0001] The application relates to a vibrating screen, in particular to a linear vibrating screen that uses rubber springs and motor supports to adjust the amplitude and vibration direction angle, and is applicable to material screening under different working conditions. Background technique [0002] Vibrating screen is a very important screening equipment, which is widely used in mining, metallurgy, chemical industry, construction, road construction and sanitation industries. It is mainly used for screening, grading, washing, de-intermediation and dehydration of materials. [0003] Amplitude and vibration direction angle are important parameters affecting the performance of the vibrating screen. The selection of amplitude and vibration direction angle is determined according to the particle size and properties of the screened material. The smaller the amplitude or the larger the vibration direction angle, the shorter the throwing distance of the material ea...

AI Technical Summary

Problems solved by technology

[0004] At present, the design and use of vibrating screens are mostly only for a single working condition, without considering the situation of multiple working conditions. The amplitude and vibration direction angle are fixed and cannot be adjusted.

If the characteristics of the screened material change, it is necessary to redesign and assemble the vibrating screen to achieve the purpose of adjusting the amplitude and vibration direction angle, which greatly increases the production cost and reduces the production efficiency
