Screening and refining device for solid fertilizer

Abstract

The invention discloses a screening and refining device for solid fertilizer. The device comprises a machine shell, supporting legs, a base, damping springs, a power supply box, a control cabinet, a sundry material port, a feeding hopper, a discharging port, a material plate, a screening plate, a telescopic rod, a mounting block, a material collecting box, a grinding roller, a conveyor belt, a servo motor, a steel wire filter screen, a stop lever, a lifting block, a material containing hopper and a transmission rod. The screening and refining device for the solid fertilizer has the beneficialeffects that the main working process of the device is carried out in the machine shell so as to prevent the influence of the external environment; through arrangement of the screening plate, the fertilizer can be preliminarily screened after being poured into the device; the telescopic rod driven by electric power drives the screening plate to shake left and right, so that the fertilizer on the surface of the solid block fertilizer is rubbed on the steel wire filter screen so as to fall off; through the inclination angle of the screening plate, the hard solid blocks which have lost the fertilizer property gradually roll into the material collecting box; and the vibration generated by the device in the working process is reduced through the design of the damping springs, so that the noisegenerated by the device is reduced.

Description

Technical field [0001] The invention relates to a screening and refining device, in particular to a screening and refining device for solid fertilizers, and belongs to the technical field of fertilizer processing. Background technique [0002] In the planting process of modern agriculture, chemical fertilizers are often used to increase the nutrient level of the land, so as to increase production and accelerate crop growth. Chemical fertilizers are abbreviated as chemical fertilizers. They are fertilizers made by chemical and (or) physical methods that contain one or several nutrient elements needed for the growth of crops. They are also called inorganic fertilizers. Chemical fertilizers have simple ingredients and high nutrient content; fast fertilizer efficiency, fertilizer The characteristics of strong and fierce, because chemical fertilizers are often in solid powder form, they tend to combine with moisture in the air after being placed for a long time to make the powder soli...

Problems solved by technology

Chemical fertilizers are referred to as chemical fertilizers. They are fertilizers made by chemical and (or) physical methods that contain one or several nutrient elements needed for the growth of crops. They are also called inorganic fertilizers. Chemical fertilizers have simple ingredients and high nutrient content; The characteristics of ferocity, because chemical fertilizers are often in the form of solid powder, after a long time of storage, they will often combine with moisture in the air to make the powder solidify. In this case, the use of chemical fertilizers will cause uneven nutrient absorption in the land and affect crops. Uniform growth and waste of fertilizer, so before the use of chemical fertilizers, it needs to be thinned by machinery

[0003] The existing chemical fertilizer refinement device has certain defects in design. First, the general fertilizer refinement device simply breaks up the bulk fertilizer, and cannot screen some hard lumps that lose their fertilizer effect due to long-term solidification. Therefore, the fertilization efficiency is reduced. Secondly, when the general chemical fertilizer thinning device is thinning the partially solidified fertilizer, its mechanical vibration will cause a large noise in the device, which will affect the normal life of the surrounding people.
