A semi-automatic intermittent feeding vibrating screening device

Abstract

The invention discloses a semi-automatic intermittent material-feeding type vibration screening device. The semi-automatic intermittent material-feeding type vibration screening device comprises a rack, a material-feeding device, a screen body, a first driving device, a second driving device, a third driving device, an adjusting device, a controller and vibration support chains, a first power device is composed of a crank sliding block mechanism, a steel wire rope, a weight and the like, the tilt angle of a screening box can be adjusted by the adjusting device, the screening efficiency of materials can be improved, the adjusting device can further pour out large-particle screened objects inside the screening box, a second power device adopts the crank sliding block mechanism, the motion amplitude can be adjusted by one motor, the third driving device outputs up and down vibration, three degree of freedom motions are finally formed, materials are divided into different grades, and userscan replace a screening plate according to the actual screening material type to adapt to different materials. The semi-automatic intermittent material-feeding type vibration screening device has thenumerous advantages of being wide in application range, intermittent and even in material feeding, efficient in screening, low in cost, high in classification efficiency, high in automation degree, multiple in classification kind and the like.

Description

technical field [0001] The invention belongs to the technical field of screening machinery, in particular to a semi-automatic intermittent feeding vibrating screening device. Background technique [0002] With the rapid growth of the national economy and the development of industry, all walks of life urgently need screening machinery with large processing capacity for screening, so high-efficiency screening machinery and equipment are needed. The screening machine mainly uses the size of the material to classify, so that a part of the material with a small size passes through the sieve holes, while the material with a large size remains on the screen surface, so that the material is divided into different grades. Screening machinery is widely used in metallurgy, chemical industry, coal preparation, electric power, food, building materials, mining and other industries. There are many types of existing screening equipment, such as vibrating screens, airflow screens, rotary vi...

Problems solved by technology

The disadvantage of this kind of screening machine is that the vibration force is small, the screen hole is easy to block, the screening efficiency is low, and it is not suitable for large-scale production.

For example, the movement form is single, there is only one up and down vibration, the angle of the screen surface cannot be adjusted, it cannot be applied to complex working environments, and some materials cannot be effectively screened, and its automation is low, the effect is unreliable, and the operation is troublesome. A lot of manpower, material and financial resources are spent on screening
