Abstract

The utility model relates to an agricultural production appliance, in particular to an electric sprayer, which solves shortages that the manual knapsack sprayer is low in efficiency, and the truck mounted mechanical sprayer is inflexible in using in the prior art. The electric sprayer comprises a pesticide barrel, a liquid transport tube is connected to the lower portion of the pesticide barrel, a spray rod is connected to the upper portion of the pesticide barrel, the pesticide barrel is internally equipped with a water pump, a gas and liquid storage tank and a battery, a delivery tube is connected between a water outlet of the water pump and an inlet of the gas and liquid storage tank, and a liquid inlet pipe is connected with a water inlet of the water pump. The electric sprayer structurally miniaturizes the battery, the water pump and the gas and liquid tank and places in the pesticide barrel, and has the advantages that the pesticide barrel also can be carried manually, but substitutes a manual pressure generating device, thereby reducing amount of labor, having high degree of automation, and freeing of limitation of environment.

electric sprayer

technical field

The utility model relates to an agricultural production appliance, in particular to an electric sprayer.

Background technique

In agricultural and forestry production, in order to prevent and control various diseases and insect pests, pesticides need to be sprayed regularly. Pesticide spraying is generally carried by a manual sprayer or a vehicle-mounted sprayer that uses a gasoline engine to provide pressure. These two sprayers have their own advantages and disadvantages. The manual type is small in size and suitable for manual and flexible use. However, the pressure of the spray is generated by manual pressurization. The pressure is low and the spray effect is poor. The vehicle-mounted spraying device is powered by a gasoline engine, so it has high pressure and high spraying efficiency, but it is not flexible to use, and it cannot be used in some rugged agricultural and forestry areas.

Contents of the invention

The utility model provides an electric sprayer in order to solve the shortcomings of the low efficiency of the artificial knapsack sprayer and the inflexible use of the vehicle-mounted mechanical sprayer in the prior art.

The utility model is realized by the following technical proposals. An electric sprayer includes a medicine barrel, an infusion tube is connected under the medicine barrel, a spray rod is connected to the infusion tube, a water pump, a gas storage liquid bottle, and a battery are arranged in the medicine barrel. A catheter is connected between the water outlet of the water pump and the inlet of the gas storage liquid bottle, and the water inlet of the water pump is connected with a liquid inlet pipe.

When in use, start the water pump, pressurize the liquid medicine in the medicine barrel and part of the air into the air storage liquid bottle through the action of the water pump, and then turn on the switch on the spray rod to spray and atomize the mixture of the air storage liquid bottle.

Compared with the prior art, the utility model adopts the structure that the battery, the water pump, and the gas storage liquid bottle are miniaturized and placed in the medicine barrel. It has the following advantages. The medicine barrel can also be used manually, but it replaces the manual pressure generating device, which reduces the workload of people. The degree of automation is high, and the use is not restricted by the environment.

Detailed ways

As shown in the accompanying drawings, an electric sprayer includes a drug barrel 2, an infusion tube 8 is connected under the drug barrel 2, a spray rod 6 is connected to the infusion tube 8, a water pump 4 is arranged in the drug barrel 2, and a gas storage liquid bottle 9 , the battery 1, the water outlet of the water pump 4 and the inlet of the gas storage liquid bottle 9 are connected with a catheter 13, and the water inlet of the water pump 4 is connected with a liquid inlet pipe 12.

A strainer 11 is installed at the end of the liquid inlet pipe 12 .

A pressure control valve 10 is also installed on the gas storage liquid bottle 9, and the effect of the pressure control valve 10 is to automatically open when the pressure in the gas storage liquid bottle 9 is large enough to release a part of the pressure. Keep a safe and constant pressure in the gas storage liquid bottle 9 all the time.
