Description

Movable light and simple accurate fertilization system

Technical Field

The utility model relates to a fertigation technical field, concretely relates to accurate fertilization system of movable light letter.

Background

The fertilizer applicator (device or equipment) is the core and key equipment of the water and fertilizer integrated system, and the cost and the precision of different fertilizer applicators are greatly different. Common fertilizing equipment or devices are precision fertilizer applicators, differential pressure type fertilizer application tanks, venturi type fertilizer applicators, proportional fertilizer applicators, and the like.

First, a precision fertilizer applicator. The accurate fertilizer applicator can accurately control the concentration of the fertilizer, evenly supply required rich water to plants as required, and greatly improve the utilization rate of the water and fertilizer. But accurate fertilizer distributor is with high costs, needs to set up independent computer lab and professional operating personnel simultaneously. Second, differential pressure fertilization jar. The device utilizes rivers to get into the fertilization jar, because the pipe diameter is inconsistent, forms certain pressure differential to bring the fertilizer solution of fertilization jar the inside into the trunk line, carry out liquid manure and irrigate. The device has the advantages of simple structure, low cost, simple operation, firmness, durability and larger fertilizer supply area. But the disadvantage is that the fertilization concentration can not be controlled, the error is generally more than 15%, and the uneven fertilization in the area is easy to cause. Thirdly, a Venturi fertilizer applicator. The Venturi fertilizer applicator has a simple structure, the water inlet and the water outlet of the Venturi fertilizer applicator have different pipe diameters, so that the water flow speed is different, pressure difference is formed, and fertilizer is driven to enter a pipeline from the pesticide inlet. The device has the advantages of simple structure, low manufacturing cost, simple and convenient installation and operation and relatively good uniformity of regional fertilizer. However, the disadvantages of this device are: the fertilization error is more than 10 percent, and the fertilization error is easily influenced by the water flow speed, and the fertilization concentration fluctuation is large; in addition, the device is not suitable for large-area fertilizer supply. Fourthly, a proportional fertilizer applicator. The proportional fertilizer applicator is a fertilizer mixing device which is driven by water power and can move back and forth through a motor in a pump body to drive fertilizer at an injection opening to be accurately injected into water according to a set proportion. The device works by means of hydraulic drive, can uniformly distribute fertilizer according to a set proportion, has a general error range of 3-5 percent in the fertilizing mode, and is small in size, light in weight and simple to install. The device has the defects that the quick-wear parts need to be checked and replaced regularly, otherwise, the fertilizer preparation precision is influenced, in addition, the requirement on the water quality is higher, and the service life and the fertilizer preparation precision of the proportional fertilizer applicator are influenced by excessive impurities in water.

The realization of accurate water and fertilizer supply is the core and key of modern agriculture. Cost and accuracy are two important factors for determining the popularization of the fertilizer applicator. The requirements of improving the uniformity and precision of the water and fertilizer, reducing the cost, improving the convenience and the durability of operation and reducing the water quality are the main requirements of the precise water and fertilizer system at the present stage, and the popularization and use values of the system in production are determined.
