Spraying pressure-stable trunk whitening machine

Abstract

The invention discloses a spraying pressure-stable trunk whitening machine. The machine comprises a motor vehicle; a working arm is arranged at the front part of the motor vehicle; a spraying barrel module is arranged at the front end of the working arm, and includes a nozzle; the motor vehicle is provided with a mixed liquid box for storing paint; the mixed liquid box and the nozzle are connected through a paint conveying pipe; a liquid valve is arranged in the connecting place of the paint conveying pipe with the nozzle; a pressure storage tank is arranged on the paint conveying pipe, and is provided with a pressure sensor; the pressure sensor is electrically connected to a control circuit; and the control circuit is connected with the liquid valve, and controls opening / closing of the liquid valve. The spraying pressure-stable trunk whitening machine has the the following advantages: the trunk whitening machine is more uniform in spraying pressure and spraying effect in the spraying operation.

Description

[0001] 【Technical field】 [0002] The invention relates to a tree trunk whitening machine with stable spray pressure, which belongs to the field of tree maintenance equipment. [0003] 【Background technique】 [0004] In order to prevent tree diseases and insect pests and survive the winter safely, for many years, garden management departments and urban construction management departments at home and abroad have been afforesting trees on both sides of the road and in gardens in order to achieve one tree in winter and less insects in summer. Apply lime water and apply white liquid paint. In winter in most parts of our country, the temperature difference between day and night is large. The trunk is irradiated by the sun during the day, and the temperature on the surface of the trunk rises, especially those dark brown trunks, which are easier to absorb heat, making the temperature of the trunk rise faster, and enter the night. The ambient temperature drops rapidly, one cold and on...

AI Technical Summary

Problems solved by technology

[0006] 1. When the paint is being sprayed, only the working pressure of the pressure pump is used to make the paint fill the pipeline first, and a certain pressure is generated in the pipeline. At the moment when the spraying work starts, the nozzle reaches a certain pressure requirement to achieve the spraying effect, but This kind of pressure is maintained for a short time, and it is easy to cause the problem of sufficient pressure in the early stage and insufficient pressure in the later stage;

[0007] 2. The stirring mechanism set in the liquid tank can only stir the liquid at the rotation diameter of the stirring wheel in the tank evenly, and the area outside the rotation diameter cannot be effectively stirred, so the precipitation of the liquid in the tank has not been effectively solved;

[0008] 3. The liquid used to transport the spraying liquid pipeline and the cleaning pipeline cannot be automatically interchanged in terms of liquid exchange. If the user forgets to clean the spraying liquid delivery pipeline at the end of the work from the operating machine, the pipeline will be blocked by the sediment of the liquid , serious may make the machine scrapped

[0009] The above technical differences and defects lead to insignificant improvement in efficiency, and the reliability of the machine in use is relatively fragile, so it has not been widely used in the market.

[0010] Although some tree trunk lime water spraying machines have been designed in recent years, because it requires 2-3 people to operate, the operation is cumbersome, and it takes a long time to spray a tree. The efficiency is not much different from that of manual brushing. The main thing is that these spraying machines are difficult to overcome the blockage of liquid delivery pipes and nozzles by high-concentration liquids and cannot be used in practical applications.
