At the same time, the rotating rod 10 can also drive the blocking block 20 to rotate, which facilitates the circumferential discharge of various fertilizer raw materials through the lower discharge port, facilitating the subsequent further mixing of various fertilizer raw materials.

[0025] In this embodiment, the adjusting rod 6 is limited to rotate between the top of the isolation plate 8 and the mixing tank 1. A handwheel is fixedly installed at the top of the adjusting rod 6 corresponding to the top of the mixing tank 1.

The sliding sleeve 15 can drive the lifting plate 16 to move reciprocally, which facilitates vertical mixing and stirring of various fertilizer raw materials, thereby improving the mixing efficiency of fertilizer ratio and making it highly practical.

[0028] When using this fertilizer mixing device, according to the type of fertilizer required for vegetable planting, a corresponding number of dispensing cylinders 3 and speed regulating mechanisms 4 are installed at the top of the mixing tank 1. Before dispensing, the handwheel and adjusting rod 6 are turned. The handwheel and adjusting rod 6 drive the worm gear to rotate, and the meshing action between the worm gear and the worm wheel drives the screw 7 to rotate. The screw connection between the screw 7 and the adjusting block 13 facilitates the movement and adjustment of the adjusting block 13, so that one end of the adjusting block 13 is in close contact with the inner wall of the bottom of the dispensing cylinder 3. A rubber layer is provided on the outside of the adjusting block 13 to improve the adjustment. The sealing between block 13 and the inner wall of the discharge cylinder 3 is achieved through the self-locking capability between the worm gear and the worm. Liquid fertilizer raw materials are placed inside the discharge cylinder 3, and the screw 7 is rotated in the reverse direction via the handwheel, adjusting rod 6, worm, and worm wheel to facilitate the reverse movement of the adjusting block 13 and adjust the distance between the adjusting block 13 and the bottom inner wall of the discharge cylinder 3. This allows for convenient control of the feeding and speed of multiple fertilizer raw materials, facilitating simultaneous feeding of multiple fertilizer raw materials. Multiple fertilizer raw materials enter the fixed cylinder 9 and are driven by the servo motor 2. The rotating rod 10 rotates inside the mixing tank 1, simultaneously driving the stirring rod 19, the blocking block 20, and the fixed tube 14 to rotate. This facilitates the initial mixing of various fertilizer raw materials through the stirring rod 19 inside the fixed cylinder 9. The blocking block 20 rotates inside the lower discharge port, causing the through portion of the lower discharge port to rotate circumferentially, discharging the initially mixed fertilizer raw materials onto the top of the fixed cover 11. This facilitates the dispersion of the liquid fertilizer raw materials through the fixed cover 11. When the fixed tube 14 rotates, it can compress the sliding rod 18 through the wavy continuous groove 17. The square rod can... The sliding sleeve 15 is limited to a sliding position, allowing it to slide only upwards. This facilitates the lifting and lowering adjustment of the sliding sleeve 15 and the lifting plate 16 via the sliding rod 18. It also facilitates the lifting plate 16 to lift and press down various fertilizer raw materials for mixing, ensuring thorough mixing and uniformity of the fertilizer after proportioning, thus improving the practicality of the device. After mixing and proportioning, the solenoid valve is opened to discharge the waste material through the discharge pipe 5. The adjusting rod 6 can be manually rotated or rotated, or a different servo motor 2 can be used to drive the adjusting rod 6 to ensure synchronous material discharge.
