Background technique

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 vibrating screens, etc. The power of these screening machines is mainly the exciter, and the screen surface vibrates up and down under the action of the exciter to produce a circular shape. , linear trajectory and other movements. The movement of the screen surface makes the materials on the screen surface leave the screen surface and be thrown up, so that the fine materials can fall through the screen surface. 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 large amount of manpower, material and financial resources have been spent on screening.

Therefore, it is necessary to design a levelable multi-degree-of-freedom vibrating screening device, the screen box can output multiple degrees of freedom of motion, the inclination of the screen box can also be adjusted by the adjustment device, and the size of the screen box movement range can be adjusted by the motor , so that the efficiency of material screening can be improved to achieve the best grading effect. Users can screen materials according to their actual situation, and replace the sieve plate to adapt to different materials. It has many advantages such as reliability, simple operation, fast grading speed, high degree of automation, and many types of grading.
