The outer part of the inner tube 14 is sleeved with a spring 19. The spring 19 is used to apply elastic force to the inner tube 14, so that the water inlet 15 of the inner tube 14 is exposed from the vertical pipe 4 and is located inside the sleeve 12 under normal conditions. The bottom end of the inner tube 14 extends to the outer surface of the sleeve 12 and is threadedly connected with a plug-in tube 16. The plug-in tube 16 is communicated with the inner tube 14. The bottom end of the plug-in tube 16 is fixed with a tapered end 17.

[0024] In another embodiment provided by the present invention, a delivery pump 2 is fixed to the bottom outer wall of the medicine box 1, the inlet of the delivery pump 2 is connected to the medicine box 1, a tank body 3 is fixed to the bottom outer wall of the medicine box 1, the outlet of the delivery pump 2 is connected to the tank body 3, the delivery pump 2 delivers the selenium fertilizer solution inside the medicine box 1 to the inside of the tank body 3, a battery box 10 is fixed to the outer wall of one side of the medicine box 1, and the battery box 10 is used to power the delivery pump 2; the top of the plug-in tube 16 is connected to the connecting tube 5, and a handle 6 is fixed to the outer wall of one side of the connecting tube 5, which is convenient for applying force when the plug-in tube 16 is inserted into the soil, and the connecting tube 5 is connected to the tank body 3 through a hose , so that the selenium fertilizer solution inside the tank body 3 can enter the interior of the connecting pipe 5 and the vertical pipe 4. At the same time, a pressure sensor can be installed inside the tank body 3, so that when the pressure inside the tank body 3 reaches a predetermined value, the pressure sensor transmits the pressure information to the host computer through an electrical signal, so that the host computer controls the delivery pump 2 to stop working. When the pressure inside the tank body 3 drops, the host computer controls the delivery pump 2 to work according to the information transmitted by the pressure sensor, thereby maintaining a constant pressure inside the tank body 3 and preventing the delivery pump 2 from being damaged due to overload. The specific connection principle between the pressure sensor, the delivery pump and the host computer is the existing technology.

[0025] In another embodiment provided by the present invention, a clamp 11 is fixed to the outer wall of one side of the medicine box 1, and the vertical tube 4 is clamped inside the clamp 11. The clamp 11 is used to make the vertical tube 4 easy to fix and separate from the medicine box 1; a running wheel 7 is provided at the bottom of the medicine box 1, and a handrail 8 is fixed to the outer wall of one side of the medicine box 1. A funnel 9 is connected to the top of the medicine box 1. The funnel 9 is used to add selenium fertilizer solution to the medicine box 1. The running wheel 7 and the handrail 8 make it possible to push the medicine box 1, which is convenient for the medicine box 1 to be moved. On the one hand, the medicine box 1 can be moved, and on the other hand, more selenium fertilizer can be contained in the medicine box 1, so that there is no need to frequently replenish selenium fertilizer when fertilizing selenium-rich agricultural products; a sealing gasket 20 is provided between the plug-in tube 16 and the sleeve 12, and the sealing gasket 20 is sleeved on the outside of the inner tube 14.

The retaining ring 21 prevents the piston 13 from being separated from the sleeve 12.

[0026] Working principle: When selenium-rich agricultural products need to be fertilized with selenium fertilizer, first add selenium fertilizer solution into the medicine box 1, and use the delivery pump 2 to deliver the selenium fertilizer solution inside the medicine box 1 into the tank 3, and then the selenium fertilizer solution enters the vertical pipe 4 from the tank 3; then, hold the handle 6 to insert the plug tube 16 into the soil near the roots of the agricultural products, and press the vertical pipe 4 downward. After the vertical pipe 4 is subjected to force, it drives the piston 13 to move downward inside the sleeve 12, and compresses the spring 19, so that the inner tube 14 The water inlet 15 on the vertical pipe 4 enters the vertical pipe 4, so that the selenium fertilizer solution in the inner pipe 14 enters from the water inlet 15, and then the selenium fertilizer solution flows out from the water outlet 18, achieving the effect of applying selenium fertilizer to the roots of agricultural products. When the plug-in pipe 16 is pulled out, the elastic force of the spring 19 pops the inner pipe 14 out of the vertical pipe 4, so that the water inlet 15 of the inner pipe 14 is completely exposed from the vertical pipe 4. At this time, the selenium fertilizer solution in the vertical pipe 4 cannot enter the inner pipe 14, thereby preventing the selenium fertilizer solution from leaking.

[0027] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
