Low-pressure airflow atomizing sprayer

Abstract

The invention discloses a low-pressure airflow atomizing sprayer which comprises a machine frame, a petrol engine, an air pump, a liquid medicine box and a spray lance, wherein the petrol engine and the liquid medicine box are mounted on the machine frame, and the spray lance is connected with the liquid medicine box. The low-pressure airflow atomizing sprayer is characterized in that a sewage outlet and a one-way air guide valve are arranged at the bottom of the liquid medicine box; a spray lance switch used for adjusting the spray outlet is mounted at a position of the spray lance, which is held by hand; a suction disc port is directly connected with an outlet of a liquid pipe port; the petrol engine is directly connected with the air pump; a hemispherical net membrane for secondary noise reduction and sound deadening is mounted at a smoke exhaust port of the petrol engine; and a plurality of atomizing spray heads are mounted on the spray lance. The low-pressure airflow atomizing sprayer has the characteristics of simple structure, easiness in manufacture, low cost, high efficiency and convenience in use, and can guarantee safety of people.

Description

technical field [0001] The invention relates to a spraying device, in particular to a low-pressure airflow mist machine for spraying pesticides. Background technique [0002] In order to prevent and control diseases, insects, and weeds in agricultural production, it is necessary to spray various pesticides on crops. Pesticide spraying equipment is indispensable for spraying pesticides. Among the commonly used pesticide spraying equipment in the vast rural areas of our country, it is mainly traditional workers and farmers. Type 16 sprayer or its improved type, this type of sprayer and its improved products are designed using the principle of hydraulic atomization, and once played an important role in the development of my country's agricultural economy, but most of them have high labor intensity and liquid particles Inhomogeneous, too large atomized particles of the chemical solution, the large particles of the chemical solution cannot adhere to the surface of the crops, and in...

Problems solved by technology

[0005] The inventors have found that the sprayers disclosed in the documents above also have the following problems: Document 1 has a complicated structure and poor spray effect; Document 2 needs to use a heating circuit, which makes the structure of the sprayer more complicated and increases the weight of the sprayer

This utility model has the effects of good atomization effect, fine and uniform spray droplets, reduced labor intensity and effective improvement of production efficiency. However, after a period of trial, it is found that there are still some defects. One is that the current sprayer adopts clutch connection , so that the air pump can only work at a certain speed, and the clutch and clutch plate are relatively easy to wear; second, there is no special switch on the spray rod, and when the sprayer needs to be turned on or off, it can only be controlled by the switch of the main power supply, so the spray The size of the pesticide cannot be adjusted, and the amount of the pesticide solution cannot be controlled. Therefore, this has always been a technical bottleneck in the industry.
