A compound fertilizer suction device

Abstract

The invention relates to the technical field of agricultural irrigation device, and discloses a compound fertilizer sucking device which comprises a water inlet section, a fertilizer sucking cavity and a fertilizer outlet section. The water inlet section is connected with the fertilizer outlet section through the fertilizer sucking cavity. The water inlet section comprises a water inlet pipe, a contraction pipe and a nozzle which are sequentially communicated. The nozzle is located in the fertilizer sucking cavity. The fertilizer outlet section comprises a mixing chamber, a dispersing pipe and a fertilizer outlet pipe which are sequentially communicated. The end, away from the dispersing pipe, of the mixing chamber is communicated with the fertilizer sucking cavity. The nozzle is opposite to the mixing chamber. A plurality of fertilizer sucking holes are formed in the fertilizer sucking cavity and used for sucking various types of single-element pure fertilizer into the fertilizer sucking cavity at the same time. Various types of single-element pure fertilizer can be mixed with water at the same time, and the device is high in systematic integrity, small in occupied space, and high in fertilizer sucking performance and reliability and meanwhile effectively improves the water and fertilizer mixing efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation equipment, in particular to a compound fertilizer suction device. Background technique [0002] With the development of agricultural modernization, the importance of irrigation and fertilization systems in the development of facility agriculture, water-saving agriculture and ecological agriculture has become increasingly prominent. The fertigation system is a new technology that integrates irrigation, fertilizer absorption and fertilization. By mixing the fertilizer stock solution with clean water and supplying it to crops, it reduces the time for fertilizer absorption and fertilization, saves labor for fertilization, and improves the utilization rate of fertilizers. [0003] In the field of agricultural water-saving irrigation, the fertilizer suction device in the prior art is usually a Venturi fertilizer suction device, which is a kind of fertilizer suction device developed by us...

AI Technical Summary

Problems solved by technology

[0004] In practical applications, most of the fertilizers used in agricultural irrigation and fertilization are compound fertilizers, which are mixed with a variety of single-element pure fertilizers. When using the existing Venturi fertilizer suction device, multiple Venturi tubes are required to work at the same time. The system integration of the device is low, it occupies a large space, the throat is easy to block, the fertilizer absorption performance and reliability are low, and the mixing efficiency of water and fertilizer is low
