Because the outer part of the arc-shaped pipe 21 is provided with the floating plate 23, the floating spray head 4 is kept on the upper layer of the liquid surface along the longitudinal movement of the slide block 22 along the vertical rail 9. When the manual closing or the liquid level reaches the upper float liquid level switch 10, the third electromagnetic block valve 18 is closed, and the water injection process is finished.
When the fertilizer preparation process starts, the second electromagnetic block valve 20 and the water pump 3 are started after soluble fertilizer particles are manually filled into the fertilizer applying barrel 1, and liquid in the fertilizer applying barrel 1 is sucked out and pressurized by the water pump 3 and then is ejected from the floating spray head 4 and the fixed spray head 5. The water flow sprayed from the floating spray head 4 and the fixed spray head 5 can push the liquid nearby to deviate, so that the stirring effect is generated, and the dissolution of soluble fertilizer particles is promoted; the arc-shaped pipe 21 is fixed at the vertical rail 9 through the slide block 22 in the stirring process, so that the rotation and the vibration caused by water flow are avoided. Then the second electromagnetic cut-off valve 20 is closed, the third electromagnetic cut-off valve 18 is opened, the floating spray head 4 and the fixed spray head 5 in the fertilization bucket 1 do not discharge water any more, and fertilizer liquid formed after the soluble fertilizer particles are dissolved flows into the main irrigation pipe 19 through the third electromagnetic cut-off valve 18. In the process, if undissolved fertilizer particles are influenced by gravity and water flow and move to the water outlet hole 14, the undissolved fertilizer particles are stopped by the filter screen 2 and then precipitate at the bottom of the fertilizer barrel 1, and the blockage of a pipeline and a terminal device is avoided. When the liquid level of the fertilization barrel 1 is reduced to the lower floater liquid level switch 11, the situation that water is about to be lacked in the fertilization barrel 1 is shown, and the first electromagnetic block valve 16 and the water pump 3 are closed.
The working process of the equipment in the automatic mode is the same as that in the manual mode, but the first electromagnetic block valve 16, the second electromagnetic block valve 20, the third electromagnetic block valve 18 and the water pump 3 in the automatic mode are controlled by a microcomputer. When the liquid level in the fertilizing barrel 1 reaches the upper float liquid level switch 10, the third electromagnetic block valve 18 is automatically closed.

The bottom of the automatic charging machine 8 is provided with a metering wheel 24, the metering wheel 24 is of a fan-shaped structure, grooves of the fan-shaped structure are formed between two adjacent metering wheels 24, and each groove can contain fertilizer particles with equal mass; the metering wheel 24 is controlled to rotate by a stepping motor 25; in this embodiment, the number of the metering wheels 24 is four, a certain amount of fertilizer granules can be put into the fertilizing barrel 1 when the metering wheels 24 rotate for 1/4 circles, and the stepping motor 25 rotates for corresponding circles according to a fertilizer ratio set value. Meanwhile, the upper part of the automatic loading machine 8 is a funnel-shaped storage box 26, the bottom of the storage box 26 is provided with a film pressure sensor 27, the film pressure sensor 27 can be a DF type flexible film pressure sensor of Suzhou Nengsida electronic technology limited company, the film pressure sensor 27 can detect the amount of the pre-stored fertilizer, when the fertilizer is used up, the material shortage warning lamp 28 is turned on and stops feeding into the fertilizing barrel 1, and when the fertilizer is supplemented, the incomplete feeding process is continued.
Further, referring to fig. 5, when three channels are used for fertilization, that is, 3 fertilization barrels 1 are provided, fertilizers in different fertilization barrels 1 flow to the water pump 3 through the water outlet holes 14 to be mixed, and then flow back to the fertilization barrels 1 through the respective upper circulating water pipelines 6 and lower circulating water pipelines 7. After the stirring is finished, the fertilizers in different fertilizing barrels 1 are also mixed.
In the embodiment, the floating spray nozzle 4 and the fixed spray nozzle 5 jointly form a paddle-free stirring structure, a certain included angle is formed between the floating spray nozzle 4 and the fixed spray nozzle 5 and the central axis of the fertilization barrel 1, and the sprayed water flow pushes the liquid in the fertilization barrel 1 to rotate, so that the movement speed and mutual collision of soluble fertilizer particles in the fertilization barrel 1 are accelerated, and the dissolution speed of the soluble fertilizer particles is obviously improved; the floating spray head 4 can adapt to the conditions of different liquid level heights, so that the floating spray head 4 is always positioned on the upper layer of the liquid level, and the stirring effect is ensured; simultaneously, the filter screen 2 in the fertilization bucket 1 advances the fertilizer liquid filtration process, effectively improves the operating efficiency of equipment when fertilizer is not completely dissolved, avoids causing equipment paralysis because of blockking up.
