[0002] At present, when classifying solid materials such as ores according to particle diameter, it is often carried out by using a screening system composed of a screening mechanism with a traditional structure, such as screening equipment such as probability screens and bar screens. Although the screening equipment used in operation can meet the needs of solid material screening to a certain extent, the current traditional screening mechanism has a complex structure, and the equipment has a relatively large structural volume and self-weight. Therefore, on the one hand, the current traditional screening mechanism The energy consumption of the screening system in actual operation is relatively large, and the operation and maintenance of the equipment are difficult and costly. At the same time, it also requires a large installation space for the installation and positioning of the equipment, which is easily restricted by the environment of the site. And it leads to high construction cost and low space utilization rate of the site, which further increases the cost of current screening equipment use and maintenance. On the other hand, the screening system often includes a screening mechanism, which lacks the necessary System backup, so when the equipment needs to be maintained or the equipment fails, the entire screening system needs to be shut down, which seriously affects the continuity and reliability of the solid material screening operation, and the solid material screening The work efficiency of the operation has a serious negative impact, and it also causes a screening system to often only meet the needs of a single type of material screening operation, which seriously affects the work efficiency and flexibility of the material screening operation, and when multi-level screening is required Sorting operations often require multiple screening systems to be used at the same time, which further increases the operating energy consumption, space utilization and equipment operation and maintenance costs of the current traditional screening system

[0003] At the same time, the traditional screening mechanism currently used, when screening materials, uses the material's own weight and inertia to drive the material through the screening mechanism through a certain inclination angle, but there is no scientific basis for the angle between the material flow direction and the horizontal plane. This leads to insufficient utilization of the kinetic energy of the solid material itself during material screening, and thus leads to friction loss between the equipment and materials between the solid material and the sieve plate, box plate and other structures of the screening mechanism, and friction loss caused by friction. The phenomenon of noise pollution is serious. At the same time, it also causes the energy consumption of the screening mechanism to increase when it oscillates and screens materials, and it is very easy to cause damage to the structure of the screening mechanism due to excessive load, which seriously affects the operation of the screening mechanism. Stability, reliability, service life machine use and maintenance costs

[0004] In addition, when the current screening mechanism screens solid materials, due to factors such as equipment vibration and high-speed material flow, it is easy to cause serious dust pollution of solid materials, which not only causes waste of materials, but also seriously affects the working environment. Therefore, the current working environment during the screening of solid materials is relatively harsh, which poses a serious threat to the health of the staff, and also leads to the need to invest in higher costs for solid dust pollution control
