Device capable of directly decomposing kitchen waste into agricultural and forestry crop fertilizer and achieving water-saving irrigation

Abstract

The invention relates to a device capable of directly decomposing kitchen waste into agricultural and forestry crop fertilizer and achieving water-saving irrigation. The device comprises a container body, wherein the lower half portion of the container body is buried in soil; an anaerobic reaction chamber is vertically arranged on the inner side of the container body; the upper end of the anaerobic reaction chamber is lower than the upper end of the container body; a sealing cover is arranged at the top of the anaerobic reaction chamber; a water seal interlayer used for water injection is formed between the inner side of the container body and the outer side of the anaerobic reaction chamber; a plurality of flow valves are arranged on the lower half portion of the container body; and transparent observation windows are arranged on the side wall of the container body and the side wall of the anaerobic reaction chamber. According to the device, the kitchen waste is used for fertilizing plants while the fertilizing and irrigating efficiency is guaranteed, reasonable utilization of resources is achieved, the anaerobic environment in the device is guaranteed through a water seal feedingport, fertilizing and irrigating can be connected in parallel and work independently, an irrigating area is buried underground, a discharging port directly aims at the plants to act, and the fertilizing and irrigating efficiency is improved.

Description

technical field [0001] The invention relates to the field of sustainable utilization of kitchen waste, in particular to a device for directly digesting kitchen waste into agricultural and forestry crop fertilizers and capable of water-saving irrigation. Background technique [0002] The existing fertilization and irrigation device is combined with a water tank and a fertilizer tank. Fertilization and irrigation can work independently, which improves the efficiency of fertilization and irrigation and reduces the input of manpower and material resources; through the switch, the fertilizer flow rate can be effectively controlled, and the amount of fertilization and irrigation can be quantitatively controlled to realize irrigation. Automation of fertilization; irrigation and fertilization can be performed according to the actual growth needs of crops, which can improve the effective use of resources. The main technical problems existing in the fertilization and irrigation device...

AI Technical Summary

Problems solved by technology

The main technical problems existing in the fertilization and irrigation device: only the existing chemical fertilizers can be used for fertilization, and the degradable resources cannot be fully utilized, and the needs of the current green and environmental protection era cannot be met; the device is large in size, complex in structure, and high in use cost. Suitable for use in large fields

However, the structure of this device is complex, it occupies a large area, the object of fertilization is single, and the range of action is small.
