Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to screening equipment for soil pre-treatment. Background Art

[0002] The process of separating bulk materials into different particle sizes through one or several layers of screens is called screening. Screening equipment utilizes the relative movement between bulk materials and the screen surface to allow some particles to pass through the screen holes, thereby separating sand, gravel, crushed stone and other materials into different grades according to particle size. The screening process is generally continuous. After the screening raw materials are fed to the screening machine, materials smaller than the screen hole size pass through the screen hole and are called undersize products. Materials larger than the screen hole size are continuously discharged from the screen surface and are called oversize products.

[0003] During the soil sampling and testing process, the sampled soil needs to be further screened before testing. At this time, screening equipment is used.

However, the stability of the sieves is poor when stacked. The top sieve is subjected to less vibration than the bottom sieve, resulting in poor screening effect of the top sieve.
