[0026] The inner side of the connecting ring 505 is slidably connected to the outer side of the discharge pipe 504. After the connecting ring 505 is out of the limit position, the connecting ring 505 is slid downward to facilitate cutting off the connecting ring 505 and the spherical plug 509 for convenient maintenance.

[0027] The bottom end of the connecting ring 505 is threadedly connected with a screw rod 510, and four screw rods 510 are provided, which are equidistantly arranged at the bottom end of the connecting ring 505. The bottom end of the quantitative tank 503 is provided with a threaded hole 511, and four threaded holes 511 are provided, which are equidistantly arranged at the bottom end of the quantitative tank 503. The screw rod 510 is threadedly connected with the threaded hole 511.

With the cooperation of the threads of the bidirectional screw 606 and the movable seat 604, the two corresponding L-shaped clamping rods 605 are moved outward at the same time, so that the quantitative tank 503 can be removed, thereby facilitating the maintenance of the proportioning mechanism 5.

[0036] When in use, first set the detection value of the pressure sensor 502 according to the mixing ratio, then pour the fertilizer from the feed hopper 513 into the quantitative tank 503. When the weight of the fertilizer in the quantitative tank 503 reaches the detection value of the pressure sensor 502, stop pouring the fertilizer, and control the electric push rod 506 to extend, drive the L-shaped connecting rod 508 and the spherical plug 509 to move downward, so that the spherical plug 509 is separated from the discharge pipe 504, and the fertilizer falls from the gap between the spherical plug 509 and the discharge pipe 504, so that the quantitative fertilizer enters the mixing tank 3 from the upper hopper 4, thereby completing the quantitative mixing ratio;
