Trunk whitewashing machine

Abstract

The invention discloses a trunk whitewashing machine which comprises a motor vehicle. The motor vehicle is connected with a manipulator. A spray bucket assembly is connected to the front end of the manipulator. The spray bucket assembly comprises a left half bucket and a right half bucket which can be opened and closed. When the left half bucket and the right half bucket are closed, a trunk is clamped between the left half bucket and the right half bucket to be subjected to spraying. The manipulator comprises a lifting mechanism, a telescopic mechanism and a second connecting mechanism which is connected between the telescopic mechanism and the lifting mechanism. The lifting mechanism is connected with the motor vehicle through a first connecting mechanism. The telescopic mechanism is connected with the spray bucket assembly through a third connecting mechanism. The trunk whitewashing machine has the advantages that rotation in multiple directions can be achieved, the degree of freedom of rotation is high, and the application range of the trunk whitewashing machine is greatly broadened.

Description

[0001] 【Technical field】 [0002] The invention relates to a tree trunk whitening machine, 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 one hot, the bark on the trun...

AI Technical Summary

Problems solved by technology

[0006] 1. The freedom of rotation of the tree trunk whitening machine is not high, and the degree of use is relatively limited, and most of the adjustments are adjusted manually, which is laborious;

[0007] Second, the lifting is basically realized by a four-bar linkage mechanism, the lifting efficiency is not high, and the lifting height is relatively limited

[0008] 3. In the original tree trunk whitening machine, during the spraying process, the rotation of the working arm is usually adjusted manually. Obviously, the rotation efficiency is not high, and it is more laborious. Moreover, the rotation accuracy is not high, and it is often impossible to accurately locate the trunk to be sprayed. superior

[0009] 4. In the original tree trunk whitening machine, the spray barrel is rotatably connected to the working arm, and usually rotates freely. When spraying, as long as the trunk is partially located within the fan-shaped angle range opened by the left half barrel and the right half barrel, The spray barrel will adjust its position by itself, but after spraying the tree trunks in different positions, the spray barrel will stay at the rotation angle when the spraying is completed, which leads to the need to adjust the spray barrel back to the position when the subsequent spraying operation is performed;

[0010] 5. When the coating material is sprayed, only the working pressure of the pressure pump is used to fill the pipeline with the paint 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. However, this kind of pressure is maintained for a short time, which is likely to cause the problem of sufficient pressure in the early stage and insufficient pressure in the later stage;

[0011] 6. The spray barrel is composed of a left half barrel and a right half barrel. The bottom of the left half barrel and the right half barrel are respectively equipped with suction pipes for recycling paint. In the actual spraying process, the spray barrel cannot always maintain a horizontal state. The spray barrel When tilted, it may cause the straw at the bottom of the left half of the barrel to touch the liquid surface, while the straw at the bottom of the right half of the barrel cannot touch the liquid surface. In the air, it is easy to cause air suction, which will cause the recovery pump to be in an idling state, and long-term use will burn out the recovery pump

[0012] 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.

[0013] 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.
