Fertigation device with adjustable flow rate

Abstract

The invention discloses an irrigation and fertilizer application apparatus capable of adjusting a flow rate. The irrigation and fertilizer application apparatus comprises a rain collection box, a stirring tank, a stirring mechanism, a fertilizer dissolving tank and a distributing tank, wherein a first separation plate is vertically arranged in the rain collection box, an internal space of the raincollection box is divided by the first separation plate into a first chamber and a second chamber, a water outlet pipe is arranged in the second chamber, and the water outlet pipe is communicated with the upper end of a mixing tank; a plurality of ring-shaped separation plates are arranged in the stirring tank, and the upper end and lower end of each ring-shaped separation plate are respectivelyprovided with a guide hole; the stirring mechanism comprises a main stirring shaft and a plurality of groups of secondary stirring assemblies, the main stirring shaft is sleeved with a first sleeve, an annular first accommodating cavity is arranged in the first sleeve, and the first accommodating cavity is communicated with the mixing tank; and each group of secondary stirring assemblies comprisessecondary stirring shafts symmetrically distributed on two sides of the main stirring shaft. By arranging the distributing tank, the flow rate of the mixture after passing by different chambers of the distributing tank is different, so that the requirement of the crops for the fertilizer in different growth periods can be met.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, more specifically, the invention relates to an irrigation and fertilization device with adjustable flow rate. Background technique [0002] Using rainwater to irrigate crops is one of the irrigation methods. It can not only save water resources, but also because of the low EC value of rainwater, rainwater irrigation is also more conducive to the robust growth of crops, and the quality of crops is higher. The irrigation and fertilization facilities of modern agriculture usually use soluble solid or liquid fertilizers according to the nutrients required by different crops and the characteristics of crop fertilizer requirements. Regularly and quantitatively infiltrate the root development and growth area of ​​crops, so that the main root soil always maintains looseness and suitable water content, but the rainwater is not fully utilized, and undissolved particulate matter often occurs ...

Problems solved by technology

The irrigation and fertilization facilities of modern agriculture usually use soluble solid or liquid fertilizers according to the nutrients required by different crops and the characteristics of crop fertilizer requirements. Regularly and quantitatively infiltrate the root development and growth area of ​​crops, so that the main root soil always maintains looseness and suitable water content, but the rainwater is not fully utilized, and undissolved particulate matter often occurs during the fertilization process, which will block the dripping in the pipeline. head, which affects the fertilization effect and shortens the service life of drip irrigation equipment

Moreover, the existing irrigation and fertigation facilities do not take into account the different needs of fertilizers in different growth periods of crops, thus applying different flow rates of fertilizers
