Embodiment 1

[0029] Such as Figure 1-3 Shown in and 5, a kind of water and fertilizer integrated solid fertilizer continuous fertilization device comprises fertilizer adding device, mother liquor tank 4, irrigation water pipe 1, fertilization pipe 29, water inlet pipe 18, support 19 and controller, described fertilizer adding device, Mother liquor tank 4, fertilization pipe 29 and water inlet pipe 18 are installed on the support 19, and the fertilizer outlet of described fertilizer addition device connects fertilizer addition pipe 13 described fertilizer addition pipe 13 through several fertilizer branch pipes 11 and mother liquor tank 4 The top is connected, and the fertilizer branch pipe 11 is evenly arranged on the top of the mother liquor tank 4 . By connecting the fertilizer branch pipe 11 to the mother liquid tank 4, the fertilizer can be divided into multiple parts and dispersed into the mother liquid tank 4, which is beneficial to increase the mixing speed of the fertilizer soluti...

Embodiment 2

[0050] Such as Figure 4 As shown, the fertilizer adding device is provided with an iron remover 30 , a filter 31 is provided outside the stirring blade, and a filter 32 is provided at the inlet end of the fertilization pump 28 . The iron remover 30 generally adopts a magnet.

[0051] In this embodiment, by setting the above device, impurities in the fertilizer can be effectively removed, the blockage of the fertilization pipe 29 can be prevented, and the stability of fertilization can be effectively improved.

Abstract

The invention relates to a continuous water-fertilizer-integrated solid fertilizer applying device. The device comprises a fertilizer adding device, a mother liquor tank, an irrigation water pipe, a fertilizing pipe, a water inlet pipe, a bracket and a control system, wherein a fertilizer discharging port of the fertilizer adding device is connected with the top of the mother liquor tank through afertilizer adding pipe, the fertilizer adding pipe is connected with the top of the mother liquor tank through a plurality of fertilizer branch pipes, the water inlet pipe is communicated with a plurality of sprayers arranged on the top of the mother liquor tank, the fertilizing pipe is sequentially provided with a fertilizing pump, a fertilizing electromagnetic valve and a fertilizing flowmeter,and the fertilizing branch pipes are uniformly communicated with the irrigation water pipe. The continuous solid fertilizer applying device has the advantages that the speed of dissolving and mixingthe solid fertilizer is high, fertilization liquid is uniformly mixed with irrigation water, and the mixing speed is high; by directly detecting the concentration of the fertilizer in the water afterfertilization, fertilization control is more accurate, adjustment is more rapid, and the precision of fertilization and irrigation can be effectively improved.

Description

technical field [0001] The invention relates to a water and fertilizer integrated solid fertilizer continuous fertilization device, which belongs to the field of agricultural irrigation and fertilization machinery. Background technique [0002] The water and fertilizer integration technology is to provide the water and fertilizer solution from the pipeline to the crops in a regular, quantitative, and proportionate manner to achieve the effects of water saving, fertilizer saving, labor saving, high yield, and income increase. It is widely used in various fields of agricultural production. The key factors in the water and fertilizer integrated irrigation technology are: the precise configuration device of mother liquid and the rapid mixing device of fertilization liquid. In the water and fertilizer integrated irrigation technology, automatic control is mainly realized by controlling the EC value of the mother liquid tank and irrigation water pipes, and then precise fertilizati...
