Water-fertilizer integrated irrigation device

Abstract

The invention belongs to the technical field of agricultural machine, and especially relates to a water-fertilizer integrated irrigation device. The water-fertilizer integrated irrigation device comprises a water pipe and a water branch pipe; the water branch pipe is communicated with a fertilizer dissolving device; the water pipe is communicated with a fertilizer liquid injection device; the fertilizer dissolving device is communicated with the fertilizer liquid injection device via a fertilizer liquid delivery pipe; an output end of the fertilizer liquid injection device is communicated with an irrigation pipe network; the fertilizer dissolving device comprises a fertilizer dissolving tank and a buffer tank communicated with the fertilizer dissolving tank; a stirring device is arranged in the fertilizer dissolving tank; a first filter screen and a second filter screen are arranged in the fertilizer dissolving tank; the fertilizer dissolving tank is communicated with the buffer tank via a fertilizer liquid pipe; the bottom of the fertilizer dissolving tank is arranged to be higher than the top of the buffer tank; and a material slag collection device is arranged on the fertilizer dissolving tank. The water-fertilizer integrated irrigation device is rapid in fertilizer dissolving speed, excellent in dissolving effect, and excellent in mixing effect of fertilizer liquid with water flow, and is capable of increasing fertilization efficiency and fertilization quality, and improving fertilizer utilization ratio effectively.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a water and fertilizer integrated irrigation device. Background technique [0002] In recent years, due to the promotion and popularization of facility agricultural technology, liquid fertilizer has been widely used in modern agricultural production. The integration of water and fertilizer is a new agricultural technology that integrates irrigation and fertilization. Its advantage lies in making full use of the watering and irrigation facilities of modern agriculture, mixing soluble solid or liquid fertilizers according to the nutrients required by different crops and the characteristics of crop fertilizer requirements, blending the fertilizer solution with irrigation water, and then using it under control The pipe system forms drip irrigation through pipes and drippers, uniformly, regularly and quantitatively infiltrating the growth area of ​​the crop root system,...

AI Technical Summary

Problems solved by technology

[0003] However, in the fertilization part of the existing water and fertilizer integrated device, undissolved particulate matter often occurs during the fertilization process, which will block the dripper in the pipeline, affect the fertilization effect, and shorten the service life of the drip irrigation equipment

The fertilizer mixing currently used is to introduce the fertilizer into the fertilizer pool. In order to fully dissolve the fertilizer, it needs to be stirred manually, which increases the labor intensity and reduces the production efficiency.
