A liquid fertilizer retail machine

Abstract

The present invention provides a liquid fertilizer retail machine. The liquid fertilizer retail machine comprises an air compressor, at least one liquid fertilizer storage tank and a fertilizer outlet tube communicated with the liquid fertilizer storage tank, wherein a fertilizer inlet is formed in the liquid fertilizer storage tank, a first valve is arranged on the fertilizer outlet tube, the air compressor is communicated with the interior of the liquid fertilizer storage tank through an air tube, a backflow branch tube is connected to the fertilizer outlet tube, one end of the backflow branch tube is connected with the fertilizer outlet tube, the other end of the backflow branch tube is connected with the interior of the liquid fertilizer storage tank, and a second valve is connected to the backflow branch tube. According to the liquid fertilizer retail machine, the backflow branch tube is additionally arranged on the fertilizer outlet tube so that backflow of liquid fertilizer can be achieved and the liquid fertilizer can be circulated and move between the fertilizer outlet tube, the backflow branch tube and the liquid fertilizer storage tank, the uniformity of the liquid fertilizer is kept, and therefore it is guaranteed that the physical characteristic of the liquid fertilizer can be more stable, and crystallization and layering of the liquid fertilizer are avoided in the long-time placement process. Besides, the liquid fertilizer retail machine has the functions of heating, automatic discharge, blocking prevention, automatic washing and the like, the functions can be all controlled through a controller, and the working efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the field of fertilizer distribution, in particular to a liquid fertilizer retail machine specially used in a fertilizer distribution station system. Background technique [0002] Compared with solid water-soluble fertilizers, liquid fertilizers have the advantages of fast dissolution, good fertilizer efficiency, uniform nutrients, comprehensive nutrients, flexible formulas, and low production costs, and are very suitable for water-fertilizer integrated irrigation and fertigation systems. In recent years, with the rapid promotion and application of water and fertilizer integration technology in my country, the amount of liquid fertilizer application is also rising sharply. [0003] The terminal sale of liquid fertilizer is an important link for its products to reach farmers directly, and plays a very important role in the promotion and application of liquid fertilizer. However, liquid fertilizers are affected by dosage forms, ...

AI Technical Summary

Problems solved by technology

This patented product has a certain promotion effect on the terminal sales of liquid fertilizers, but there are some problems in the application process of this product, such as the lack of backflow and heating devices, and the long-term standing of liquid fertilizers in storage tanks, resulting in uneven nutrients in liquid fertilizers; The lack of anti-clogging system and automatic cleaning system will easily lead to stratification and clogging of liquid fertilizer; liquid fertilizer storage tanks share a platform base, which cannot realize automatic metering and discharging, and the accuracy of automatic metering is not high, which is not convenient for long-term use
