White paint spraying machine, with high lifting efficiency, for trunk

Abstract

The invention discloses a white paint spraying machine, with high lifting efficiency, for a trunk. The white paint spraying machine comprises a motor vehicle. A working arm is arranged at the front part of the motor vehicle. A spraying barrel assembly is arranged at the front end of the working arm, and comprises a left half barrel and a right half barrel, which can be opened or closed. When the left half barrel and the right half barrel are closed, the trunk is clamped between the left half barrel and the right half barrel to be sprayed with paint. A lifting mechanism is arranged between the working arm and the front part of the motor vehicle, and comprises an outer lifting cylinder, an inner lifting cylinder and a lifting cylinder. One of the outer lifting cylinder and the inner lifting cylinder is connected with the front part of the motor vehicle, and the other one is connected with the working arm. The lifting cylinder drives the outer lifting cylinder and the inner lifting cylinder to relatively move in the vertical direction. The white paint spraying machine has the advantage that the efficiency is higher when the working arm ascends or descends.

Description

[0001] 【Technical field】 [0002] The invention relates to a tree trunk whitening machine with high lifting efficiency, 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 ...

AI Technical Summary

Problems solved by technology

[0006] The lifting of the working arm is basically realized by a four-bar linkage mechanism, the lifting efficiency is not high, and the lifting height is relatively limited

[0007] Due to these technical differences and defects, the improvement of efficiency is not obvious, and the reliability of the machine is relatively fragile, so it has not been widely used in the market.

[0008] 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 manual brushing, and more 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.
