Organic fertilizer screening equipment with low damage percentage

Abstract

The invention belongs to the technical field of organic fertilizer processing, and particularly relates to organic fertilizer screening equipment with the low damage percentage. The organic fertilizerscreening equipment comprises a shell, a hopper, a first screening unit, a second screening unit, a third screening unit and an object storing box; the first screening unit is arranged below the hopper and comprises a first motor, a worm, a first driving roller, a pushing device, a first driven roller, elastic conveying belts and a first discharging hopper; the conveying belts are arranged to bea set of narrow cloth belts which are staggered up and down through a set of limiting wheels and are arranged in a layered staggering manner; organic fertilizer particles to be screened gradually falllayer by layer, the material falling speed is decreased, and falling damage due to too high speed is avoided. According to the organic fertilizer screening equipment, the first screening unit is usedfor screening chippings, particles with one particle size range are screened out through the second screening unit, and particles with another particle size range are screened out through the third screening unit; and multi-stage screening is carried out on organic fertilizer, and the damage percentage can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer processing, in particular to an organic fertilizer screening device with low crushing rate. Background technique [0002] Organic fertilizers are mainly derived from plants and (or) animals, and are applied to the soil to provide plant nutrition as carbon-containing materials whose main function is. It is processed from biomass, animal and plant waste, and plant residues, eliminating toxic and harmful substances, and rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food producti...

Problems solved by technology

[0005] At the same time, because during the sieving process of organic fertilizer particles, the sieved organic fertilizer particles will inevitably collide with containers or equipment, causing the qualified particles after sieving to be broken, thereby affecting the yield, so a reduction The equipment that causes organic fertilizer particles to be broken due to sieving becomes particularly important
