Vibration source upper-mounted type environment-friendly old asphalt screening machine

Abstract

The invention discloses a vibration source upper-mounted type environment-friendly old asphalt screening machine. The machine comprises a material rack, a screening rack and a vibration rack. The material rack and the vibration rack are arranged at the bottom and the top of the screening rack correspondingly. A discharging trough is formed on the upper surface of the material rack. The screening rack comprises a C-shaped framework. The inner wall of one side of the C-shaped framework is rotationally connected with a rotating shaft, the outer side of the rotating shaft is fixedly connected witha mounting connecting plate, a swing rack is arranged on the inner side of the C-shaped framework, and the swing rack is composed of side panels and rotating rollers. Through a first drive motor anda second drive motor, a transmission screening belt achieves oriented conveying and slightly shakes while the swing rack swings, screening holes are prevented from being blocked, a turnover rack rotates in an oriented manner to achieve turnover and scatter caked materials, materials are lifted and turned over to the other side of the swing rack through bent plates, finally screened fine materialsare screened into the discharging trough, and the material screening effect is improved; and compared with the prior art, the screening holes of a screening device are not prone to being blocked, andthe effect of evenly scattering materials is achieved.

Description

technical field [0001] The invention relates to the field of screening devices, in particular to an environment-friendly asphalt old material screening machine with an upper vibration source. Background technique [0002] The screening machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size. During the sieving process, due to the collision and friction between the particles and the screen, a large noise will be generated, which will affect the surrounding residents' environment and cause noise pollution. Especially the vibrating source top-mounted screening machine, the noise generated not only affects the environment, but also has a negative impact on the operator's body. [0003] It is an effective means to solve noise pollution by...

Problems solved by technology

During the screening process, due to the collision and friction between the particles and the screen, a large noise will be generated, which will affect the surrounding residents' environment and cause noise pollution.

Especially the vibrating source top-mounted screening machine, the noise generated not only affects the environment, but also has a negative impact on the operator's body

[0003] It is an effective means to solve the noise pollution by using the conveyor belt screening device to make the relative motion between the granular material and the screen surface, but when this method is actually used, the screen hole is easy to be blocked, and the agglomerated material is transported by the stable moving conveyor belt. Difficult to disperse, resulting in poor screening of materials
