Fertilizer crushing and scattering device

Abstract

The invention discloses a fertilizer crushing and scattering device, which comprises a bottom support plate, spiral fertilizer beating rollers, a fertilizer secondary collision crushing box, a and scattering circular disc and two side support plates, wherein one side support plate is fixedly connected onto each of two sides of the bottom support plate; the tops of the two side support plates are connected through a connecting element; a plurality of spiral fertilizer beating fertilizer rollers are arranged between the two side support plates; a hydraulic motor drives one spiral fertilizer beating roller to rotate; the two adjacent spiral fertilizer beating rollers are connected through a first transmission device; one end of the fertilizer secondary collision crushing box is hinged onto the connecting element; a plurality of crushing sharp parts are arranged on the side wall facing the spiral fertilizer beating roller; a hydraulic cylinder body is hinged onto each side support plate; apiston rod is hinged onto the secondary collision crushing box; a plurality of throwing and spreading circular discs are arranged on the bottom support plates and are connected through a second transmission device. The fertilizer crushing spreading device can perform secondary crushing on big barnyard manure; the crushing rate and the crushing effect are improved; meanwhile, ordinary fertilizerscan also be scattered.

Description

technical field [0001] The invention relates to the technical field of fertilizer crushing, in particular to a fertilizer crushing and spreading device. Background technique [0002] Organic fertilizers refer to various animal wastes and plant residues, which are formed by using physical, chemical, biological or a combination of the three treatment technologies, after a certain processing technology, to eliminate harmful substances and meet the harmless standards. A type of fertilizer in relevant national standards and regulations. Through the use of organic fertilizers, the yield of crops can be increased, the quality of agricultural products can be improved, the amount of chemical fertilizers used can be reduced, and the harm caused by the use of chemical fertilizers can be reduced or avoided, which is in line with the long-term development of the country. The existing fertilizer crushing and throwing mechanism cannot crush the fertilizer or the crushing effect is not goo...

AI Technical Summary

Problems solved by technology

The existing fertilizer crushing and throwing mechanism cannot crush the fertilizer or the crushing effect is not good. It just simply throws the fertilizer, which is not conducive to the decomposition of the fertilizer and cannot meet the real needs of farmers.
