The invention relates to a trunk whitewashing machine with stable injection pressure, and belongs to the field of tree maintenance equipment.
[ background of the invention ]
For the prevention and control of tree diseases and insect pests and the safe overwintering of trees, garden management departments and city construction management departments at home and abroad are used for brushing lime water and white liquid paint on greening trees on two sides of roads and in gardens for Xia Shaomo insects which are used for brushing one tree in winter. In winter in most areas of China, the temperature difference between day and night is large, the temperature of the surface of the trunk rises when the trunk is irradiated by sunlight in the daytime, particularly, the trunk which is dark brown is easier to absorb heat, so that the temperature of the trunk rises faster, the temperature of the trunk is reduced rapidly when the trunk enters night, the bark on the trunk is easy to crack when the trunk is cooled and heated, particularly, the thicker trunk is dark in color, the toughness of the tissue is poor, the bark is easy to crack, and the cracked bark can often become a place where plant diseases and insect pests occur and a place where worm eggs overwinter. The lime has certain sterilization and insecticidal effects, and can kill eggs parasitized on the cracked parts of the barks and accelerate the healing of the cracked parts. In the daytime, part of sunlight can be reflected, the temperature difference is reduced, the germination and flowering period of trees are delayed while freezing is prevented, and early spring frost damage is prevented.
However, the lime water is coated on the trunks by manually using a brush and a stick for many years, and for northern areas in China, the great quantity of trunks are coated in dozens of days before winter, which is an unforeseen thing. The trees are brushed for several times in the south in one year, and the trees are brushed again when the lime water of the trunks is washed almost by rainwater. In recent years, there are several machines for mechanically brushing the trunk with lime water, such as the chinese invention patent: [ trunk whitewashing machine ] patent number: ZL2013200219457.6, [ pavement trunk whitewashing machine ] patent number: 201320087220.3 [ machines for spraying white liquids on tree trunks ] patent No. 2013 0709457.0 all suffer from the following problems in use:
1. when the coating is sprayed, the pipeline is filled with the coating firstly by using the working pressure of the pressure pump, a certain pressure is generated in the pipeline, and a certain pressure requirement is met at the spray head at the beginning of spraying to realize the spraying effect, but the pressure maintaining time is short, so that the problems of enough pressure in the early stage and insufficient pressure in the later stage are easily caused;
2. the stirring mechanism arranged in the liquid tank can only uniformly stir the liquid at the rotation diameter of the stirring wheel in the tank, and the area outside the rotation diameter can not be effectively stirred, so that the precipitation phenomenon of the liquid in the tank is not effectively solved;
3. the liquid used for conveying the spraying liquid pipeline and the cleaning pipeline can not be automatically exchanged in the aspect of liquid exchange, and if a user forgets to clean the spraying liquid conveying pipeline when the work is finished in the operation machine, the pipeline can be blocked by the sediment of the liquid, and the machine can be seriously scrapped.
These technical differences and drawbacks make the improvement of efficiency insignificant and the reliability of the machine in use weak, and therefore cannot be used in the market in general.
Although some trunk lime water spraying machines are designed in recent years, the operation is complicated because 2-3 people are needed for operation during working, the time for spraying a tree is long, the efficiency is not different from manual painting, and more importantly, the spraying machines are difficult to overcome the defect that high-concentration liquid blocks a liquid conveying pipeline and a spray head and cannot be put into practical application.
