[0024] See also Figure 1-4 A saline-alkali land soil improvement fertilizer precision fertilization device includes: a mobile vehicle 1 and a fixed shell 11, and the fixed shell 11 is installed on the top of the mobile vehicle 1.

[0025] Furthermore, a feeding cover is provided on the top of the fixed shell 11 .

[0026] The precise control mechanism 2 is arranged inside the fixed shell 11. The precise control mechanism 2 includes a mounting block 21. There are two mounting blocks 21, which are respectively mounted on the left and right sides of the inner wall of the fixed shell 11. The two mounting blocks 21 are fixedly connected through a mounting shell 22. A servo motor 23 is fixedly connected to the front of the inner wall of the mounting shell 22. A ring block 24 is fixedly connected to the surface of the output shaft of the servo motor 23. A sealing plate 25 used in conjunction with the ring block 24 is fixedly connected on the inner wall of the mounting shell 22 and on the left and right sides of the ring block 24. The sealing plate 25 is in contact with the ring block 24 on one side close to the ring block 24. A plurality of storage grooves 26 are provided on the surface of the ring block 24. An electric push rod 27 is fixedly connected to the inner wall of the storage groove 26. The output end of the electric push rod 27 is fixedly connected to A moving block 28, one end of the moving block 28 away from the electric push rod 27 is fixedly connected to a pressure sensor 29, and the side of the pressure sensor 29 away from the moving block 28 is fixedly connected to a placement plate 210, the surface of the placement plate 210 is in contact with the inner wall of the storage groove 26, and two positioning rods 211 are fixedly connected to the inner wall of the storage groove 26, and the surface of the positioning rod 211 is slidably connected to a positioning block 212, and the side of the positioning block 212 close to the moving block 28 is fixedly connected to the moving block 28 through a connecting block 213, and a stopper 200 is fixedly connected to the positioning rod 211, and the bottom of the mounting shell 22 is fixedly connected to a discharge pipe 214 adapted to the storage groove 26, and the shape of the discharge pipe 214 is rectangular, and the bottom end of the discharge pipe 214 passes through the fixed shell 11 and the moving vehicle 1 from top to bottom in sequence and extends to the outside of the moving vehicle 1.

[0027] Specifically, when the amount of fertilizer in the storage tank 26 needs to be increased, the electric push rod 27 is first started. The electric push rod 27 drives the placement plate 210 to move closer to the block 200 through the moving block 28 and the pressure sensor 29, thereby increasing the volume of the fertilizer stored in the storage tank 26. The pressure sensor 29 then senses the weight of the fertilizer stored in the storage tank 26 to reach the required amount.

[0028] A driving stirring mechanism 3 is arranged inside the fixed shell 11. The driving stirring mechanism 3 includes a funnel 31. The funnel 31 is installed on the inner wall of the fixed shell 11. A stirring motor 32 is fixedly connected to the top of the fixed shell 11. The bottom end of the output shaft of the stirring motor 32 penetrates the fixed shell 11 and extends into the interior thereof. A stirring rod 33 is fixedly connected to the bottom end of the output shaft of the stirring motor 32. The bottom end of the stirring rod 33 penetrates the funnel 31 and extends into the interior thereof. A material guide pipe 34 adapted to the annular block 24 is fixedly connected to the bottom of the funnel 31. The bottom end of the material guide pipe 34 penetrates the mounting shell 22 and extends into the interior thereof. The side of the material guide pipe 34 close to the annular block 24 contacts with the annular block 24. An electromagnetic valve is provided on the left side of the material guide pipe 34. The shape of the material guide pipe 34 is cylindrical.

[0029] Furthermore, a controller is installed on the left side of the fixed shell 11, and the control methods of the servo motor 23, the electric push rod 27, the solenoid valve on the guide tube 34, the pressure sensor 29 and the stirring motor 32 are all controlled by the controller matched therewith, and the control circuit can be realized by simple programming by technicians in this field, which is common knowledge in this field and will not be elaborated here.

[0031] When in use, open the feeding cover and feed fertilizer into the funnel 31, then start the stirring motor 32, the stirring motor 32 drives the stirring rod 33 through the output shaft to mix and stir the fertilizer, and when fertilization is needed after the stirring is completed, open the solenoid valve on the guide pipe 34, so that the fertilizer enters the storage tank 26 at the top through the guide pipe 34, and the weight of the fertilizer is sensed by the pressure sensor 29. When the fertilizer reaches the set value, the signal is transmitted to the controller, and the controller starts the servo motor 23. The servo motor 23 drives the annular block 24 to rotate through the output shaft, so that the next storage tank 26 moves to the position corresponding to the guide pipe 34, and when the storage tank 26 at the bottom is opened downward, the fertilizer in the storage tank 26 is discharged to the saline-alkali soil through the discharge pipe 214.
