Example Embodiment

[0028] Example 1

[0029] Such as Figure 1-3 As shown in and 5, a water-fertilizer integrated solid fertilizer continuous fertilization device includes a fertilizer addition device, a mother liquor tank 4, an irrigation pipe 1, a fertilization pipe 29, an inlet pipe 18, a bracket 19, and a controller. The fertilizer addition device, The mother liquor tank 4, the fertilizer pipe 29 and the water inlet pipe 18 are installed on the bracket 19, and the fertilizer outlet of the fertilizer adding device is connected to the fertilizer adding pipe 13. The fertilizer adding pipe 13 passes through a plurality of fertilizer branch pipes 11 and the 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. The fertilizer branch pipe 11 is connected with the mother liquor tank 4, so that the fertilizer can be divided into multiple parts and dispersed into the mother liquor tank 4, which is beneficial to increase th...

Example Embodiment

[0049] Example 2

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

[0051] In this embodiment, by providing the above-mentioned device, the impurities in the fertilizer can be effectively removed, the clogging of the fertilizer pipe 29 can be prevented, and the stability of fertilizer application 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...
