Abstract
The utility model discloses a kind of back-carrying pedal sprayer, be connected bottom backpack cartridge case with the feed tube of piston transfer valve, the discharging tube of piston transfer valve is connected with booster jar; Described booster jar middle and lower part is connected with backpack cartridge case by liquid back pipe, pressure regulator valve, and booster jar bottom is connected with spray boom by catheter; Be provided with hydraulic piston and pneumaticpiston in the valve pocket of piston transfer valve, be provided with back-moving spring above hydraulic piston, the lower end of piston transfer valve is ridden footwear by snorkel and vapour-pressure type and is connected.Its scientific structure design, the potential energy utilizing high low head during human body walking to be formed, is reduced labour intensity during operation, can be regulated the pressure in booster jar as required by pressure regulator valve, easy to operate, time saving and energy saving, has practicality significantly.
Description
Technical field
The utility model relates to a kind of agricultural machinery equipment, particularly relates to a kind of back-carrying pedal sprayer.
Background technology
Pesticide sprayer is farm implements indispensable during agro-industry is produced, and wherein knapsack sprayer is the most general, is especially widely used in vast rural area.Although current knapsack sprayer is comparatively small and exquisite, work is comparatively flexible, need pressurize on the other hand during its work, grips spray lance on the other hand, and operation comparatively bothers, and operator's labour intensity is large, easily tired, brings some inconvenience to agricultural production.
Utility model content
For overcoming above-mentioned technical problem, it is simple that the utility model provides a kind of structure, design science, uses human bady gravitational to provide atomisation pressure, to reduce the back-carrying pedal sprayer of labour intensity.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of back-carrying pedal sprayer, and comprise a backpack cartridge case, be connected bottom it with the feed tube of piston transfer valve, the discharging tube of piston transfer valve is connected with booster jar; Described booster jar middle and lower part is connected with backpack cartridge case by liquid back pipe, pressure regulator valve, and booster jar bottom is connected with spray boom by catheter; Described feed tube and discharging tube are all connected to the upper end of piston transfer valve by check valve, the hydraulic piston of being separated by up and down and pneumaticpiston is provided with in the valve pocket of piston transfer valve, both are connected by concentric connecting rod, be provided with back-moving spring above hydraulic piston, the lower end of piston transfer valve is ridden footwear by snorkel and vapour-pressure type and is connected; The bottom that described vapour-pressure type rides footwear is telescopic sole of calming the anger, and the inner chamber of sole of calming the anger is connected with snorkel by seal nipple.
The utility model has following beneficial effect: when operator carries the walking of backpack cartridge case, vapour-pressure type is ridden footwear generation air pressure and is carried out the work of driven plunger transfer valve, solution in backpack cartridge case is delivered in booster jar by piston transfer valve, owing to reducing the gas compartment after solution increase in booster jar, therefore generation air pressure, liquid in booster jar is depressed in spray boom, the final object realizing spraying.Its scientific structure design, the potential energy utilizing high low head during human body walking to be formed, is reduced labour intensity during operation, can be regulated the pressure in booster jar as required by pressure regulator valve, easy to operate, time saving and energy saving, has practicality significantly.
