Fertilizer preparing device, sprinkler with fertilizer preparing device and fertilization method

Abstract

The invention relates to a fertilizer preparing device. The fertilizer preparing device comprises at least two fertilizing mixing tanks, a fertilization pump and a stirrer, the fertilization pump is communicated with the at least two fertilizer mixing tanks and used for pumping and discharging materials in the fertilizer mixing tanks, and the stirrer is used for stirring the materials in the fertilizer mixing tanks. According to the fertilizer preparing device and a fertilization method, fertilizer can be supplied continuously and uninterruptedly, the fertilization speed is high, the efficiency is high, the problem that the labor intensity of manual fertilization is too large is solved, the problem of high cost is solved, and good economic benefits and social benefits are achieved.

Description

technical field [0001] The present invention relates to a fertilizer preparation device, a sprinkler irrigation machine comprising the fertilizer preparation device and a fertilization method, in particular to a fertilizer preparation device used to cooperate with farmland irrigation and fertilization machinery---for example, a central pivot sprinkler irrigation machine . Background technique [0002] Chinese patent 201210357371.6 discloses a mobile irrigation vehicle. A fertilization tank is arranged on the frame, and the water inlet pipe and outlet pipe of the fertilization tank are respectively connected to the water inlet side and the water outlet pipe of the water outlet side of the valve, and a manual valve is respectively set on the water inlet pipe and the water outlet pipe of the fertilization tank , by adjusting the two manual valves, the water pressure of the above-mentioned inlet and outlet pipes produces a pressure difference, so that the fertilizer liquid in t...

AI Technical Summary

Problems solved by technology

At present, the central pivot sprinkler has problems such as no fertilizer preparation device and the use of fertilization pumps alone, resulting in uneven fertilization.

[0004] Moreover, the existing fertilizer preparation device has poor continuous fertilization ability, and the amount of one-time containing fertilizer solution is small. After spraying and fertilizing, the mixed fertilizer needs to be injected into the fertilizer applicator again. When fertilizing a large area of ​​land, it is necessary to repeatedly shut down the machine Then spray and fertilize, which brings many disadvantages such as low work efficiency and slow fertilization speed. At the same time, the amount of fertilization is uncontrollable, resulting in waste
