Improvements in an agricultural manual sprayer for preventing leakage of fluids such as insecticides, herbicides or fungicides that comprises tank with a large storage capacity into which a pressure vessel is installed. A manually activated pumping assembly is connected with the inferior section of the pressure vessel and also with the inferior section of the tank. The pumping assembly comprises a reciprocating piston pump for extracting the fluid from the storage tank and pressurizing it within the pressure vessel. The pressurized fluid is applied with a hose and a throttle valve attached to the pressure vessel. The assembly also comprises a double walled piston and barrier against leakage consisting of a ring with interior lips which seal it against the cylinder preventing the exit of fluid, forcing it to remain in the collection chamber until it is emptied with the downward movement of the piston, returning the liquid from the collection chamber to the storage tank through a return hose and internal ducts.

The invention relates to a spraying device for dispensing liquids that can be worn on the back, which has a tank (2), a hand lever (4), a pump (12), and a pressure vessel, wherein the pressure vessel is formed by a cavity in the hand lever (4) and the pump (12) is arranged in the cavity. The piston rod (13) of the pump is rotatably connected to a lever element (15) of the hand lever. A connection port (16) for a hose having a spray nozzle is integrated in the hand lever. The compact design of the spraying device enables a larger tank volume and more comfortable use. The spraying device can be economically produced, because the number of components is small.

摘要:
Manual apparatus for dispensing liquid agricultural chemicals comprises a backpack (30) supporting a reservoir (31) for liquid chemical, a fan (33) for generating air streams, and liquid spray generating means (35 a ) which comprises nozzles (36) for injecting liquid chemical to be dispensed into the air streams, the spray generating means being mounted such that the liquid spray pattern generated by it is always behind the operator. The apparatus can include a plurality of nozzles arranged around an arcuate path to lie in a common plane substantially at right angles to the intended direction of travel of the operator, and arranged to discharge liquid chemical rearwardly of the said common plane.
