The invention provides a mesh-size-adjustable multiple particle continuous automatic screening method. The method comprises the steps that by means of a conveyor belt, the corresponding first conveyorbelt with different meshes is replaced to be located between a first driving wheel and a first driven wheel, and then adjustment of the mesh size is achieved; when screening is conducted by means ofthe meshes formed in the first conveying belt, the screening requirements of the particles with the different sizes can be met, and due to the fact that the whole replacement process is conducted automatically, the operation of replacing a screening frame can be simplified; in addition, continuous automatic screening of various particles can be achieved, and the method is particularly suitable forscreening of circular particles.
Description
technical field [0001] The invention belongs to the field of crop screening, and in particular relates to a continuous automatic screening method for multi-type particles with adjustable sieve hole size. Background technique [0002] During the growth of granular crops such as soybeans, the fruits they bear may vary in size due to environmental factors. Usually, crops with larger fruits look better and can be sold at a higher price. In order to differentiate and sell granular crops to maximize the economy, size screening of granular crops is required. The current screening device can usually only screen one type of particulate matter. If different types of particulate matter are screened, the screening frame needs to be replaced manually, which is very troublesome, and the current screening device cannot realize the screening of various types of particulate matter. Continuous automatic sieving. Contents of the invention [0003] The invention provides a method for contin...
