Liquid level control spiral tube flow injection fertilizer micro-irrigation spray multifunctional combined equipment

Abstract

The invention discloses liquid-level controlled multifunctional combined equipment with functions of fertilizer injection, micro-irrigation and spraying by spiral pipe flow. The equipment consists of a hand-pull type mini-vehicle, a solution barrel, an A type solution booster engine, a B type solution booster engine, a solution conveying hose, a spiral flow liquid fertilizer adding assembly and the like. Two pieces of equipment for raising the liquid fertilizer and medicinal solution are respectively driven by using the two solution booster engines, wherein a direct-current storage battery for storing energy is arranged in the A type solution booster engine and is charged by using alternating current by virtue of a charger to drive a minitype pressure pump so as to conveniently move the whole set of unit for injecting the fertilizers, spraying the liquid fertilizers and spraying pesticides; 220V alternating current of the B type solution booster engine is changed into 12V low-voltage direct current by virtue of a current-changing adapter in a waterproof box so as to drive a minitype water pump, thus, the equipment starts safely under the environment of high humidity of a greenhouse; a liquid-level sensor is arranged in the solution barrel, the addition of the fertilizers can be controlled as planned, and the equipment shuts off automatically after the application amount is finished; the two solution booster engines are controlled by the liquid-level sensor in the solution barrel and are individually used according to the requirements, and therefore, the equipment is convenient to operate and has a good use effect.

Description

technical field [0001] The invention belongs to the technical field of water-saving and fertilizer-saving water-fertilizer integration equipment, and relates to a set booster that can be controlled by a liquid level sensor and driven by a low-voltage DC power supply or a battery to pressurize liquid fertilizer, fertilize micro-irrigation pipes with spiral tubes, and move spraying, etc. The functional structure is a liquid level control spiral tube flow injection fertilizer micro-irrigation spray multifunctional combined equipment. Background technique [0002] With the in-depth and rapid development of protected agriculture technology in this field, in order to save water and fertilizer and promote production increase, in recent years, according to the advocacy of the Ministry of Agriculture, the Ministry of Water Resources and other departments, the majority of domestic agricultural areas have been installed in greenhouses, greenhouses and other facilities The micro-irrigat...

Problems solved by technology

[0003] Although the above-mentioned equipment has its own advantages, the farmers reported that they still have many shortcomings in practical application. For example, the differential pressure fertilization tank needs to install a regulating valve on the branch pipe, which affects the setting of the water flow, working pressure, pipeline Fertilizer and water are uneven, single-function and fixed equipment, and the cost is relatively expensive; Venturi fertilizers have the problems of unstable fertilizer absorption liquid and inability to work when the pipeline flow rate is low; the price of proportional fertilizer inhalers is relatively high. The market price is about 1,500 yuan each, and the pressure difference of its branch pipes is small and cannot absorb fertilizer liquid, so it is not suitable for installation and application on water pipes in greenhouses and greenhouses; AC electric fertilizer pumps are bulky and heavy in structure, and there is no liquid level on them The controller is inconvenient to move; the structure of the fertilizer machine is complex, the function is single, and the price is expensive, so farmers are not willing to use it; the operation of spraying pesticides and fertilizer spraying equipment on the back of a person requires manpower, which not only consumes physical strength, but also disperses the liquid medicine It also has a great impact on the operator's body
