Description

Technical Field

[0001] The utility model relates to an agricultural sprayer, in particular to a remote agricultural convenient sprayer for spraying liquid medicine for plant protection. Background Art

[0002] Most of the orchard spraying in my country uses a pump to supply liquid for direct spraying. Although the liquid pressure is high, it is difficult to achieve a perfect combination of spray gun liquid atomization and range, which often results in rain-style spraying and waste of liquid. At present, large-scale air-assisted sprayers are large and clumsy, which is inconvenient for many orchards to operate, and the spraying is not targeted and wastes liquid. Small backpack misters cannot achieve large-scale spraying due to limited storage of liquid and electricity, and it is even more difficult to achieve the expected spraying effect when spraying tall trees such as fruit trees. Summary of the invention

[0003] The utility model provides a convenient long-distance agricultural pesticide blowing machine, which uses a composite hose composed of a liquid guide tube and a conductor for long-distance liquid and power transmission. A fan-shaped nozzle can be arranged in a flat elliptical tube at the front of the air delivery device to spray the liquid medicine, and then a strong wind is used to atomize and blow the liquid medicine, thereby improving efficiency and saving pesticides.

[0004] The purpose of the utility model is achieved in this way. The present scheme is to make an air delivery device, wherein the rear part of the air delivery device is a circular tube, the middle part is a conical tube, and the front part is a flat elliptical tube. The electric fan is installed in the circular tube at the rear of the air delivery device, and a fan-shaped nozzle is installed in the flat elliptical tube at the front of the air delivery device. A rear handle is installed at the rear of the air delivery device, and a speed regulating button of the electric fan is arranged on the rear handle. A front handle is installed in the middle of the air delivery device, and a water valve switch is installed on the front handle. A conduit is passed through the side hole on the air delivery device to connect the water valve switch and the fan-shaped nozzle respectively. The present scheme uses a 48-volt battery for power supply (such as a battery on an electric tricycle), and a diaphragm pump is placed next to a medicine barrel. A composite hose is synthesized by arranging a conductor outside the liquid guide tube for long-distance liquid infusion and power transmission. The battery is electrically connected to the pressure-sensitive electric switch on the diaphragm pump, and the conductor of the composite hose is electrically connected to the battery and the electric fan. The liquid infusion tube of the composite hose is connected to the liquid supply port of the diaphragm pump and the water valve switch on the front handle. When spraying pesticides on fruit trees, the suction pipe of the diaphragm pump is placed in the medicine barrel. The operator holds the rear handle and the front handle in both hands, and adjusts the wind speed of the electric fan output at any time according to the height and distance of the sprayed crops. The water valve is opened to switch the diaphragm pump to start the liquid supply, and the water valve is closed to switch the diaphragm pump to stop the liquid supply. The liquid sprayed from the fan-shaped nozzle is atomized by the wind again in the elliptical pipe mouth and then blown onto the crops. This method of spraying is convenient and flexible to achieve long-distance infusion and power transmission for blowing and spraying liquid. The cooperation of the fan-shaped nozzle and the flat elliptical air outlet is conducive to the re-atomization of the liquid and can widen the spraying area and increase the range of the liquid, which can improve the spraying efficiency and reduce the waste of liquid.
