Fertilizer multi-stage crushing device for agriculture

Abstract

The invention discloses a fertilizer multi-stage crushing device for agriculture. The fertilizer multi-stage crushing device comprises a housing, a motor, a partition plate and a crushing hammer; thepartition plate is horizontally fixed at the middle part of the housing; an upright guide cylinder is fixedly arranged on the upper surface of the partition plate; a feed chute is formed between the guide cylinder and the housing; a circle of oblique material guide block is arranged at the bottom of the feed chute; a plurality of breaking edges are fixedly arranged at the lower surface of the crushing hammer; corresponding extrusion holes are formed in the part, under the breaking edges, of the partition plate; and two mutually extruded crushing rolls are arranged below the partition plate. Byadopting crank arms to drive a lifting plate and the crushing hammer to move up and down to strike the partition plate, a fertilizer on the partition plate is extruded and crushed, and the breaking edges can extrude the fertilizer out from the extrusion holes, so that continuous feeding and crushing of the fertilizer are realized; and the fertilizer crushed for the first time falls into the spacebetween the two crushing rolls and is crushed again, and the fertilizer is crushed for two times, so that the crushing efficiency is improved and the crushing uniformity is ensured.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a multistage crushing device for agricultural fertilizer. Background technique [0002] Fertilizer grinder is a device for squeezing and grinding fertilizer. It is used in many places such as home, pesticide store and some pharmaceutical factories. Today's fertilizer grinder has complex structure, poor applicability, troublesome operation, and poor crushing effect; not only It wastes time, reduces efficiency, and also leads to a decrease in output, which brings inconvenience to people. The size of the crushed fertilizer is different, resulting in a difference in fertilizer quality, affecting the quality of fertilizer, and is not conducive to the sale of fertilizer. Contents of the invention [0003] The object of the present invention is to provide a multi-stage crushing device for agricultural fertilizers to solve the problems raised in the above-mentioned background technology.
