Agricultural fertilizer multi-stage crushing device

Abstract

The invention discloses a multistage crushing device for agricultural fertilizers, which comprises a housing, a motor, a partition and a crushing hammer; the partition is horizontally fixed in the middle of the housing, and a vertical guide is fixed on the upper surface of the partition There is a feeding trough between the guide cylinder and the housing, and a circle of inclined material guide blocks is arranged at the bottom of the feeding trough, and several crushing ribs are fixedly arranged on the lower surface of the crushing hammer, directly below the crushing ribs Corresponding extrusion holes are opened on the partition; two crushing rollers extruding each other are installed under the partition. The invention drives the lifting plate and the crushing hammer to move up and down through the set curved arm, impacts on the partition plate, squeezes and crushes the fertilizer in it, and the crushing edge can squeeze the fertilizer out of the extrusion hole to realize continuous feeding and crushing of the fertilizer. The fertilizer crushed once falls between the two crushing rollers for crushing again, and the fertilizer is crushed twice to improve the crushing efficiency and ensure the uniformity of crushing.

Description

Technical field [0001] The invention relates to an agricultural machine, in particular to a multi-stage crushing device for agricultural fertilizers. Background technique [0002] Fertilizer grinder is a device that squeezes and grinds fertilizer. It is used in many places such as homes, pesticide shops and some pharmaceutical factories.
