[0002] Whitewashing tree trunks is a common gardening and forestry measure, mainly used to protect the health of trees and promote their growth. When tree trunks are painted white, they are covered with lime water, which can reflect 10% of the sunlight back. In this way, the heat absorption is reduced, and the tree trunks will not freeze and crack due to the huge temperature difference between day and night. In addition, it can prevent pests and diseases, protect trees from the influence of the external environment, and improve the cleanliness of the garden landscape.

[0003] At present, most of the tree trunk whitewashing devices used in the market adopt the spraying method. The worker holds a spray pipe and carries a container with slurry on his back. The container is connected to the spray pipe, and a spray head is installed at the front end of the spray pipe. The spray head has a single head and an arc-shaped spray head with multiple liquid outlets. Regardless of the type of spray head, the workload of tree whitewashing is relatively large, the work efficiency is low, and the specific environmental conditions of trees outdoors are diverse. In some specific environments, it is not convenient to use existing whitewashing equipment to whitewash trees completely.

[0004] The Chinese utility model patent with patent application number 202222994599.8 discloses a handheld fruit tree whitening device, wherein a plastic hose is installed in the first section of the telescopic handheld pole, one end of the plastic hose is connected to the lime water delivery hose through a valve switch, and the other end of the plastic hose is connected to the connecting block of the first section of the handheld pole, the external thread of the connecting block is connected to the internal thread of the first section of the handheld pole, the external thread of the connecting block is reduced in diameter and connected and fixed with a sealing ring and a fastening ring to the plastic hose, the second section of the handheld pole and the third section of the handheld pole are extended backward along the plastic hose, and an anti-slip sleeve is installed on the third section of the handheld pole; the external thread of the end of the third section of the handheld pole is connected to the internal thread of the fastening sleeve to fix the plastic hose; the external thread of the connecting block is also connected to the internal thread of the semi-circular spray frame shaft, and the semi-circular spray frame shaft passes through the protective cover and is fixed to the semi-circular spray frame through a ring buckle, and micro-sprinklers are evenly distributed inside the semi-circular spray frame.
