The bottom of the feeding cylinder 9 is connected to the inlet 13, and the side wall of the feeding cylinder 9 is connected to the outlet 14. The motor and the feeding rod 10 are coaxially connected. The motor includes a hydraulic cylinder 3 and a feeding cylinder 4. The oil inlet end of the hydraulic cylinder 3 is connected to the oil inlet 5, and the oil outlet end of the hydraulic cylinder 3 is connected to the oil outlet 6. The feeding cylinder 4 is installed at the bottom of the hydraulic cylinder 3, and the feeding cylinder 9 is installed at the bottom of the feeding cylinder 4. A piston 7 is installed inside the cylinder body of the hydraulic cylinder 3. An oil rod 8 is coaxially connected to the piston 7. The telescopic end of the oil rod 8 is equipped with a feeding rod 10 that extends into the cavity of the feeding cylinder 4.

[0030] Furthermore, a lever 15 is provided between the pump body components. Both ends of the lever 15 have oblong grooves 16, which correspond to the connecting parts 12. The connecting parts 12 slide within the oblong grooves 16, and the oblong grooves 16 and connecting parts 12 are rotatably connected. A sliding groove 17 is provided on the lever 15, and a rotating rod 20 is connected within the sliding groove 17. The rotating rod 20 is connected to a support base 21, which is slidably connected to the machine body 1. A connecting plate 18 is connected to the lever 15 by screws. Multiple threaded holes 19 are evenly provided on the lever 15, and the connecting plate 18 is rotatably connected to the rotating rod 20. A guide rail 24 is connected to the machine body 1, and a guide groove 25 is provided on the support base 21 corresponding to the guide rail 24.

A scale line 26 is provided on the support base 21, and a proportional line 27 is provided on the machine body 1 corresponding to it.

[0031] Furthermore, two sets of mounting brackets 2 are symmetrically connected to one side of the body 1, and the mounting brackets 2 are detachably connected to the body 1.

[0032] The working process of this utility model is as follows:

[0033] First, the lever 15 between the two pump body assemblies changes its fulcrum by adjusting the position of the support seat 21 on the guide rail 24. By loosening the fastening bolts 23, the support seat 21 is moved along the guide rail 24, aligning the scale line 26 on the support seat 21 with the proportion line 27 on the machine body 1. Then, the bolts are tightened to fix the position of the support seat 21, adjusting the required material mixing ratio. Next, the connecting plate 18 connects to the lever 15 through different threaded holes 19, thus determining the fulcrum of the lever 15. Consequently, the output of the two pump bodies is output according to the set ratio, shortening the stroke of the pump body assembly closer to the fulcrum and increasing the stroke of the pump body assembly farther from the fulcrum, thereby achieving dynamic adjustment of the material ratio and precise material mixing.

[0034] Then, the external hydraulic source drives the piston 7 in the oil cylinder 3 through the oil inlet 5, which in turn drives the oil rod 8 to reciprocate. The feeding rod 10 connected to the oil rod 8 synchronously drives the feeding rod 11 to move up and down in the feeding cylinder 9. At the same time, the other feeding rod 11 is driven to move up and down in the feeding cylinder 9 through the middle lever 15. When the feeding rod 11 rises, a negative pressure is formed in the feeding cylinder 9, and the material is sucked in from the bottom feed inlet 13. When the feeding rod 11 falls, the material is discharged from the side outlet 14 under pressure. Both sets of pump body components suck the spray paint from the feed inlet 13, and the spray paint with high pressure generated in the cylinder is discharged from the outlet 14, completing the mixing of the spray paint.
