Mobile fermentative fertilizer preparation apparatus for bird guano

Abstract

The invention discloses a mobile fermentative fertilizer preparation apparatus for bird guano. The mobile fermentative fertilizer preparation apparatus comprises a supporting device, a walking device,a box body, a straw crushing device, a guano feeding device, a fermentation additive adding device, an agitating device, a pushing device, a main drive device, a hydraulic discharging device, a biological deodorizing device, an electric instrument box, a hydraulic cover plate and a hydraulic sealing door. According to the apparatus, apparatuses of each process of conventional production lines forraw material crushing, homogenization, fermentation, oxygen supply, moisture regulation, heating and heat preservation, deodorization, conveyance and the like are effectively integrated in a closed aerobic fermentation composting apparatus; not only is an investment decreased and is a floor area saved, but also an operating sanitary condition is ameliorated. Crushed crop straw and a fermentationadditive are mixed with the bird guano; a physical property of the bird guano is adjusted; external abundant high-efficiency fermentative microorganisms are introduced; a fermentative technological condition is optimized, and a fermentation period is shortened.

Description

technical field [0001] The invention relates to the field of agricultural organic solid waste treatment, in particular to a mobile poultry manure fermentation fertilizer making equipment. Background technique [0002] One of the important ways of resource utilization of poultry manure in my country is to produce organic fertilizer, which mainly adopts biological treatment technology, including natural composting, high-temperature composting, anaerobic fermentation, etc. Among them, the production process of commercial organic fertilizer generally adopts high-temperature aerobic composting technology . For bulk livestock manure such as cow manure and pig manure, the production is generally organized according to the principle of building a fixed production line and centralized treatment nearby, but for poultry manure such as chickens and ducks, since the daily manure output of the farm is small and scattered, except for very large poultry farms In addition, the rest are limit...

AI Technical Summary

Problems solved by technology

[0005] The technical problems to be solved by the present invention are: the contradiction between the scattered sources of manure in small and medium-sized poultry farms and the centralized treatment; the problems of many existing production line equipments, long processes, and poor operating sanitation conditions; how to improve the physical properties of poultry manure to Favorable for rapid fermentation
