Direct-mixing type multi-purpose automatic accurate fertilizer irrigation system

Abstract

The invention relates to a direct-mixing type multi-purpose automatic accurate fertilizer irrigation system which comprises a clean water tank, a raw fertilizer tank, a venturi tube, a fast fertilizer suction electromagnetic valve, an irrigation pump, an automatic control system, an electro connecting pressure gauge and a spherical fertilizer mixer, wherein the venturi tube sucks a raw fertilizer or an acid solution into a pipeline; the fast fertilizer suction electromagnetic valve controls a fertilizer suction amount; the output end of the irrigation pump is connected with the input end of the spherical fertilizer mixer through the pipeline, the pipeline positioned between the irrigation pump and the spherical fertilizer mixer is provided with the electro connecting pressure gauge; the output end of the spherical fertilizer mixer is respectively connected with an irrigation delivery pipeline and a fertilizer suction feedback pipeline; and the irrigation delivery pipeline is provided with an irrigation electromagnetic valve and a pipeline pressure detection device. The direct-mixing type multi-purpose automatic accurate fertilizer irrigation system disclosed by the invention realizes the immediate usage of a water fertilizer after mixing by adopting the independently developed spherical fertilizer mixer, can be used for furthest shortening the mixing time of a fertilizer and water and reducing the oxidation reaction generated because the fertilize contacts with air and can prevent the fertilizer waste generated in a fertilizer mixing process, provide higher output pressure through a direct-mixing type and cover more irrigated area.

Description

[technical field] [0001] The invention relates to the technical field of agricultural machinery, in particular to a direct-mix multipurpose automatic and precise fertilization and irrigation system. [Background technique] [0002] With the rapid development of agriculture, people pay more and more attention to the food safety of crops, air and environmental pollution. Under the situation of obvious shortage of water resources, it is urgent to give fine control of fertilizer and irrigation. It is best to be able to finely and accurately control fertilization and irrigation according to the nutritional needs of plants, such as fertilization time, precise fertilizer amount and irrigation water volume, so as to save fertilizer and water resources, and avoid excessive fertilization to the air and the environment. pollute. [0003] At present, existing technologies at home and abroad have been developed and applied on automatic water and fertilizer irrigation equipment, and diffe...

Problems solved by technology

This water and fertilizer irrigation equipment has complex structure and high cost

Each of them has a water and fertilizer mixing container. Water and fertilizer enter the container without any external auxiliary device to help it mix, so it is easy to have local uneven mixing of water and fertilizer, which will lead to the detection of fertilizer concentration detection device and pH value detection device on the water and fertilizer irrigation equipment. There are errors in th
