A multi-stage crushing and refining equipment for fertilizers used in agricultural planting

Abstract

The invention discloses an agricultural planting fertilizer multi-stage crushing and refining device. The fertilizer multi-stage crushing and refining device comprises a shell, a feeding hopper, a driving device, a base and rollers. A horizontal extruding block is fixed on the output end of the driving device. Extruding plates fixed on the inner wall of the shell are arranged below the extruding block. A plurality of discharging holes are uniformly formed in each extruding plate. A plurality of extruding columns corresponding to the discharging holes are fixed on the lower side of the extruding block. A plurality of discs arranged at an equally-spaced manner are fixed on each extruding column coaxially. Air draft cavities are formed in the outer sides of a discharging barrel and crushing cavities. According to the invention, the falling large-size fertilizer is refined by the discs on the extruding columns, so as to enable the extruding block to move downwards to crush the fertilizer;and power of the driving device is utilized reasonably, energy is sufficiently utilized, and the falling fertilizer is extruded by the extruding block, so that the amount of large-size fertilizer is reduced,, the refining treatment through crushing rollers is facilitated, load of the fertilizer is reduced, and the crushing stability of the fertilizer is improved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a multi-stage crushing and refining equipment for fertilizers used in agricultural planting. Background technique [0002] Fertilizer grinder is a device for extruding and grinding fertilizer. It is used in many places such as pesticide stores and some pharmaceutical factories. Today's fertilizer grinder has complex structure, poor applicability, troublesome operation, and poor crushing effect; it is not only a waste of time. , reduces efficiency, and also leads to a reduction in output. In addition, large pieces of fertilizer directly enter the crushing mechanism for cutting when crushing, resulting in a large load on the crushing mechanism, greater damage to the blade and the motor, and a reduction in the service life of the equipment. Not conducive to production use. Contents of the invention [0003] The object of the present invention is to provide a multi-stage crushing and ref...
