Water-fertilizer-pesticide integrated irrigation system

Abstract

The invention relates to a water-fertilizer-pesticide integrated irrigation system. The water-fertilizer-pesticide integrated irrigation system comprises a water-fertilizer-pesticide integrated operation platform, a drawing device, a circuit system, a spray irrigation system, a spraying system and a water-fertilizer-pesticide automated control system, wherein the water-fertilizer-pesticide integrated operation platform comprises a mobile high frame, a hanging and lifting system, a spraying rod, a water spray head and a mist spray head; the drawing device comprises a hollow square-shaped steel rope, a fixed lantern ring, a groove wheel, a driving wheel and a steel rope driving motor; the spray irrigation system comprises a submersible pump, a main water conveying pipeline, branch pipelines and the like; the spraying system comprises a spraying vehicle frame, as well as a pesticide liquid box, a roller pump, a roller pump motor, a pesticide conveying pipe and a pesticide conveying pipe coil which are mounted on the spraying vehicle frame; and the water-fertilizer-pesticide intelligent control system comprises a programmable logic controller, a water pressure sensor and the like. The water-fertilizer-pesticide integrated irrigation system disclosed by the invention combines water-fertilizer management, plant protection and pesticide application together by creating the water-fertilizer-pesticide integrated operation platform, and three functions of irrigation, fertilizer application and pesticide spraying can be realized through one set of equipment, so that the management links are reduced and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of water-saving irrigation, and in particular relates to an integrated irrigation system of water, fertilizer and medicine, which is suitable for crops with different plant heights, especially wheat and corn, for water-saving irrigation and integration of water, fertilizer and medicine, precision and intelligence. manage. technical background [0002] 1. The continuous cropping system of winter wheat and summer corn is the main farming system in the Huanghuaihai region of my country, and plays an extremely important role in ensuring national food security. However, at present, grain production in this region is facing the problems of water shortage, serious waste of water, fertilizer and medicine, and labor shortage. The traditional high-yield technology often requires a lot of manpower and many management links, and cannot adapt to the development of modern agricultural mechanization and the needs of simplified culti...

Problems solved by technology

After searching the existing technical literature, the Chinese invention patent "a micro-spray irrigation and fertilization system integrating water and fertilizer (CN201410587147)" discloses the water-fertilization integration technology of micro-spray irrigation, and the Chinese invention patent "wheat and corn annual production variable fertilizer-water integration Irrigation system (CN201410499375)” discloses the technology of integrated water and fertilizer management of wheat and corn using micro-spray belts, and the Chinese invention patent “A water and fertilizer integration technology model suitable for northern tea gardens (CN201310000482)” discloses the use of micro-spray belts in northern tea gardens Technology for integrated management of water and fertilizer, but none of them involve intelligent management technology for integrated water, fertilizer and medicine

[0004] 3. In addition, the existing fixed sprinkler irrigation and micro sprinkler irrigation technologies require a lot of equipment and high cost; the moving function of the mobile sprinkler irrigation technology is not perfect, and often can only realize the automation of one-way movement

[0005] 4. Most of the existing plant protection spraying machines are difficult to use on high-stalk crops such as corn. Although there are inventions of spraying machines such as high ground clearance, they generally require special tractor traction, and general tractor traction requires special space. lanes, wasting arable land area

[0006] 5. The design requirements of water-saving irrigation technology and plant protection spray technology are very different in terms of water supply equipment, pipeline systems, nozzles, etc., and it is difficult to use existing water-saving irrigation or plant protection spray facilities and technologies to realize the integrated management of water, fertilizer and medicine
