Tree trunk whitening device and spraying control method thereof

Abstract

The invention discloses a tree trunk whitening device, and belongs to the field of plant maintenance equipment. The tree trunk whitening device comprises a spraying barrel, the spraying barrel comprises a left half barrel body and a right half barrel body which are rotationally connected with each other, and at least one of the left half barrel and the right half barrel is internally provided witha nozzle; a barrel opening state and a barrel closing state exist between the left half barrel and the right half barrel, in the barrel opening state, a trunk enters the spraying barrel and reaches apreset position in the spraying barrel, and in the barrel closing state, the trunk is clamped between the left half barrel and the right half barrel for spraying; and the trunk whitening device is further provided with an induction switch used for sensing whether the trunk reaches the preset position or not. The invention further discloses a spraying control method of the tree trunk whitening device. The spraying control method adopts automatic control. According to the tree trunk whitening device and the spraying control method thereof, the advantages that the spraying operation efficiency is improved, and the labor cost is greatly reduced are achieved.

Description

【Technical field】 [0001] The invention relates to a trunk whitening equipment and a spraying control method thereof, belonging to the field of tree maintenance equipment. 【Background technique】 [0002] 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 ...

AI Technical Summary

Problems solved by technology

[0004] However, there are inconveniences in this type of whitening equipment at present, especially the preparation work before spraying. The operator needs to align the spray barrel with the trunk, and after alignment, the trunk slowly enters the spray barrel. After entering, it is necessary to judge Whether the spray barrel has reached the predetermined position, and after confirming the arrival, the nozzle will be turned on for spraying. The whole process is more cumbersome
