The invention relates to a mechanical creepage-type chemical mixing device used for an atomizing
machine, which comprises a
plunger pump, wherein the
plunger pump is provided with a water inlet and a water outlet, the water inlet is connected with a water container, the water outlet is connected with a spray gun component, and a
plunger of the
plunger pump is driven by the power of a plunger
crankshaft. The mechanical creepage-type chemical mixing device is characterized in that a
cam is arranged at the other end of the plunger
crankshaft, more than one roller-shaped press roller is embedded in the
cam, a housing is mounted outside the press roller, a creepage
pipe is arranged between the housing and the press roller, the creepage
pipe is compressed on the inner wall of the housing when the press roller rolls, and one end of the creepage
pipe is connected with a
pesticide mother liquid container and the other end thereof is connected with the water inlet of the
plunger pump. According to the technical scheme, the plunger
crankshaft and the roller-shaped press roller mounted on the
cam are coaxially driven by the same one power force, so that the flow rate of the
plunger pump and the flow rate of the creepage pipe are increased or reduced at the same time, which can achieve the effect of dynamically mixing the chemicals at a constant proportion and ensure that the whole atomizing
machine can mix the chemicals at an accurate proportion and spray the chemical mixture. The mechanical creepage-type chemical mixing device used for the atomizing
machine has significant progresses and positive results.
