Smoke sprayer

Abstract

The invention relates to a smoke sprayer and belongs to the technical field of agricultural machines. The smoke sprayer comprises an engine, a carburetor, a spraying pipe, a start gas source, an oil tank and a pesticide tank. The oil tank is communicated with the engine through an oil conveying pipeline provided with the carburetor. A gas outlet of a combustion chamber of the engine is communicated with the spraying pipe. The side face of the end, away from the engine, of the spraying pipe is provided with a nozzle. The nozzle is communicated with the pesticide tank through a pesticide pipeline. The combustion chamber of the engine is communicated with the pesticide tank through a waste gas pipeline. The combustion chamber of the engine is communicated with the start gas source. A radiating cavity is arranged outside the spraying pipe. The smoke sprayer is characterized in that an outlet of the radiating cavity is flush with an outlet of the spraying pipe, the combustion chamber is communicated with the radiating cavity, and a filter device is arranged between the combustion chamber and the radiating cavity. According to the smoke sprayer, a filter net is directly utilized for filtering some waste gas produced by the engine, the waste gas is exhausted into the radiating cavity after heat insulation, air in the radiating cavity is forced to flow, and the radiating effect is enhanced.

Description

[0001] This application is a divisional application with an application date of April 16, 2014, an application number of 201410152129.4, and an invention title of "fog machine". technical field [0002] The invention relates to a fog machine, which belongs to the technical field of agricultural machinery. Background technique [0003] At present, the fog machine is also called a smoke sprayer, a spray machine, a trigger fog machine, a thermal fog machine, a pulse fog machine, a gas fog machine, a fuel fog machine, etc. The pulse fog machine is designed and manufactured by using the pulse jet principle. The fog machine with the functions of pesticide application, fertilization, insecticide and sterilization can make the medicine or fertilizer into a smoke shape, so that the medicine or fertilizer has excellent penetrability, diffusion and adhesion, and has strong resistance to rain erosion. It is easy to operate, can greatly reduce the dosage of medicines, has high work effic...

Problems solved by technology

[0004] However, the current fog machines use natural air cooling to dissipate heat, so that when the fog machines work in a hot environment or for a long time, they will overheat and reduce the spraying efficiency.
