[0034] Irrigation canals are used to apply fertilizers while irrigating farmland, which is often referred to as "fertigation" or "water-fertilizer integration" technology. This is a method of dissolving fertilizers in water and delivering them directly to the roots of crops through an irrigation system. This method can improve the utilization efficiency of fertilizers, reduce fertilizer loss, and reduce pollution to the environment. Fertigation usually requires precise control of the concentration and application amount of fertilizers to ensure that crops receive enough nutrients without excessive amounts. In addition, fertigation can also be used in combination with modern agricultural technologies such as drip irrigation and sprinkler irrigation to further improve the efficiency of irrigation and fertilization. In this way, farmers can manage water resources and fertilizers more effectively, increase crop yields and quality, and reduce the impact on the environment. Based on the above status quo, how to manufacture a fertilization device that can be set on an irrigation canal is a technical problem that needs to be solved in this field.

[0035] In view of this, the present application provides a fertilization device, and manufactures a fertilization device that can be set on an irrigation canal.

The telescopic discharge port extends into the fertilizer flushing cavity through the docking port, and a plurality of fertilizer flushing holes 301 are provided on the wall surface of the fertilizer flushing mechanism 3.

[0038] When this embodiment is used, the storage mechanism 1 is fixed on the irrigation canal, and fertilizer is added to the storage mechanism 1. The fertilizer enters the telescopic fertilizer delivery mechanism 2 through the discharge port 102. After passing through the telescopic fertilizer delivery mechanism 2, the fertilizer enters the fertilizer flushing cavity of the fertilizer flushing mechanism 3. The fertilizer flushing mechanism 3 contacts the flowing water in the irrigation canal. Since a plurality of fertilizer flushing holes 301 are provided on the fertilizer flushing mechanism 3, the water in the irrigation canal can flush and take away the fertilizer in the fertilizer flushing mechanism 3 through the fertilizer flushing holes 301. By adjusting the telescopic fertilizer delivery mechanism 2, the distance between the telescopic feed port and the telescopic discharge port can be controlled, so that the water entry depth of the fertilizer flushing mechanism 3 in the irrigation canal can be controlled, thereby adjusting the amount of fertilizer taken away from the fertilizer flushing cavity by the water flow.

The connecting portion 2032 is specifically an extendable component. After adjusting the telescopic length of the telescopic adjustment section 202, the sleeve ring 2031 is sleeved in the annular groove 2021. After determining the length of the connecting portion 2032, the fixed end 2033 is fixed on the wall surface of the storage mechanism 1. This can fix the length of the entire telescopic fertilizer delivery mechanism 2 and prevent the telescopic adjustment section 202 from being telescopically elongated.

[0043] In a specific embodiment, if Figure 1 and Figure 2 As shown, the telescopic fertilizer delivery mechanism 2 uses a bellows, the first part of the bellows constitutes a connecting section 201, and a thread matching the bellows is provided in the interface of the discharge port 102, and the first part is screwed and connected in the discharge port 102.

A section of the bellows near the bottom is unfolded to form the second part, and different unfolding positions of the bellows correspond to different unfolding lengths, and different unfolding lengths correspond to different target telescopic lengths.

[0044] In a specific embodiment, any circle of corrugation on the second part of the corrugated tube can be used as the annular groove 2021, the sleeve ring 2031 is sleeved in the annular groove 2021, the connecting part 2032 is a rope, one end of the rope is connected to the sleeve ring 2031, and a protruding structure is provided on the wall of the storage mechanism 1. After the rope is straightened, the other end is wound around the protruding structure as the fixed end 2033, so that the length of the entire corrugated tube can be fixed to prevent the corrugated tube from being elongated. Generally, the corrugation corresponding to the annular groove 2021 is selected from the 1st to 10th circle from the top of the second part.

[0045] Figure 3 Shown Figure 1 Schematic diagram of part of the structure. Figure 4 Shown Figure 3 Schematic diagram of the bottom structure. In one embodiment, as Figure 3 and Figure 4 As shown, the fertilizer flushing mechanism 3 includes a first body 302 and a second body 303 connected up and down. The docking port is arranged at the top position of the first body 302. The second body 303 is connected to the first body 302 through a split connector 3010, and the first body 302 and the second body 303 are configured to form a fertilizer flushing cavity, and the fertilizer flushing cavity is communicated with the docking port.

[0046] In one embodiment, if Figure 3 As shown, the size of the fertilizer flushing hole 301 provided on the side wall of the second split body 303 gradually decreases from top to bottom, which can help adjust the amount of fertilizer flushing. When the amount of fertilizer flushing needs to be reduced, the length of the telescopic adjustment section 202 is adjusted to reduce the water entry depth of the second split body 303. At this time, the fertilizer flushing hole 301 entering the water is a small-sized fertilizer flushing hole 301, which can further reduce the amount of fertilizer flushing; when the amount of fertilizer flushing needs to be increased, the length of the telescopic adjustment section 202 is adjusted to increase the water entry depth of the second split body 303. At this time, the fertilizer flushing holes 301 entering the water are large-sized fertilizer flushing holes 301 and small-sized fertilizer flushing holes 301, which can further increase the amount of fertilizer flushing.
