Crusher for preparation of agricultural fertilizer

Abstract

The invention discloses a crusher for preparation of agricultural fertilizer. The crusher comprises a frame body and a crushing box arranged on the frame body, wherein a feeding hopper is arranged onthe top of the crushing box; a material storage cavity is formed in the bottom of the crushing box; the bottom of the material storage cavity is connected with a discharging hopper; a material storagebox is arranged under the discharging hopper; a second motor is fixed to one side of the material storage box, and a control box is arranged on the other side of the material storage box; a dust collecting box is arranged on the side, far away from a first motor, of the top end of the crushing box; and a fan is arranged on the outer side of the dust collecting box. Stirring blades are arranged inthe material storage box of the crusher and can be used for rapidly stirring the fertilizer, a heating wire is arranged inside the material storage box and can be used for heating the fertilizer, thus the wet caking fertilizer can be rapidly stirred into particles, and the stirring process is accelerated. A sliding rod, a hydraulic telescopic rod and a third motor are arranged, so that crushing fan blades can do reciprocating motion back and forth while rotating and crushing is more thorough.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to a pulverizer for preparing agricultural fertilizers. Background technique [0002] In agricultural production, fertilizer is a crucial factor. Agricultural fertilizers are generally uniform particles when they leave the factory. However, due to the long storage time, the fertilizer is easy to absorb water and agglomerate, which is not convenient for fertilization. The agglomerated fertilizer cannot be fully absorbed by plants, which affects the efficiency of the fertilizer. The traditional fertilizer crushing device uses Ring mill or flat mill crushing, the crushing output is low, the crushed particles are rough, the cost is high, and rolling crushing is also useful. Generally, the fertilizer needs to be completely dried, which affects the full use of fertilizer efficiency. At the same time, there is much dust and dust in the fertilizer crushing process The noise is loud, th...

Agricultural fertilizers are generally uniform particles when they leave the factory. However, due to the long storage time, the fertilizer is easy to absorb water and agglomerate, which is not convenient for fertilization. The agglomerated fertilizer cannot be fully absorbed by plants, which affects the efficiency of the fertilizer. The traditional fertilizer crushing device uses Ring mill or flat mill crushing, the crushing output is low, the crushed particles are rough, the cost is high, and rolling crushing is also useful. Generally, the fertilizer needs to be completely dried, which affects the full use of fertilizer efficiency. At the same time, there is much dust and dust in the fertilizer crushing process Loud noise, serious environmental pollution, easy blockage of fertilizer processing equipment in the production process, difficult maintenance, seriously affecting the healthy development of the fertilizer industry
