Fertilizer preparation device, sprinkler machine containing fertilizer preparation device and fertilizing method

Abstract

The invention relates to a fertilizer preparation device, which comprises: a fertilizer mixing tank (1), a stirrer (2), a fertilizer storage tank (3), a fertilizer conveying pump (4) and a fertilizerapplying pump (5), wherein the stirrer (2) is used for stirring materials in the fertilizer mixing tank (1); the fertilizer storage tank (3) is communicated with the fertilizer mixing tank (1); the fertilizer conveying pump (4) is arranged between the fertilizer mixing tank (1) and the fertilizer storage tank (3) and is respectively communicated with the fertilizer mixing tank (1) and the fertilizer storage tank (3); the fertilizer applying pump (5) is communicated with the fertilizer storage tank (3) and is used for pumping and discharging the materials in the fertilizer storage tank (3). According to the fertilizer preparation device and the fertilizer application method, the fertilizer application speed is high, the efficiency is high, and the problems of overlarge labor intensity of manual fertilizer application and high cost are solved; the fertilizer preparation device and the fertilizer application method have good economic benefits and social benefits.

Description

technical field [0001] The 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 for 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 the fertilization tank is pumped into the outlet pipe to fertilize the crops during irri...

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
