A seedling planting and pesticide spraying device with automatic pesticide mixing and proportioning

Abstract

The utility model relates to the technical field of equipment for seedling planting, and discloses a seedling planting pesticide spraying equipment with automatic pesticide mixing and proportioning, which comprises a box body, a pump body and a spray gun group, and a pesticide injection mechanism is arranged on the box body; a piston is pushed by an electric telescopic rod to inject a quantitative gas into the interior of a medicine bottle, and under the action of the gas pressure, the medicine will push a first seal seat to open the gap on the medicine injection sealing ring, thereby realizing quantitative injection of the medicine; during use, multiple pesticide injection mechanisms can be added on the box body according to requirements, quantitative injection of different medicines is realized, when the medicine bottle is screw-mounted on a connector, a top seat will support a second seal seat to open the gap on a lower check valve sealing ring, so that the medicine bottle can maintain a sealed state without being connected to the connector, avoiding the leakage of the medicine, and a third spring supports a third seal seat to be connected to an upper check valve sealing ring, avoiding the medicine in the medicine bottle from entering a gas cylinder through a gas cap.
