Description

Technical Field

[0001] The utility model belongs to the technical field of tree maintenance equipment, in particular to a tree trunk whitewashing device. Background Art

[0002] Trunk whitewashing is a simple yet effective gardening technique that can protect trees from the elements and extend their lifespan while also beautifying them.

[0003] At present, the most common way to whitewash tree trunks is for gardeners to apply paint on the tree trunks with a brush. The device used in this method of whitewashing tree trunks is simple, but the work efficiency is low. In the process of whitewashing tree trunks, gardeners need to apply the paint on the tree trunks several times to apply a sufficient thickness of paint. At the same time, since the paint absorbed by the brush is inconsistent each time, the paint applied is uneven, part of the tree trunk may be exposed, and the protective effect brought by the whitewashing cannot be fully enjoyed, thereby increasing the risk of damage to the trees.

[0004] In view of the drawbacks of manual whitening of tree trunks using a brush, a tree trunk whitening machine is disclosed in the document with publication number CN219129682U. The device is provided with a medicine box, a whitening rod and a nozzle. The liquid inlet end of the whitening rod is connected to the medicine storage chamber through a hose and a delivery pump. The delivery pump is electrically connected to a battery. The nozzle is arranged at the liquid outlet end of the whitening rod. The paint is delivered to the nozzle by controlling the delivery pump. The whitening rod is manually held and moved on the tree trunk. Although the tree trunk whitening machine can improve the efficiency of tree trunk whitening and reduce labor costs, it requires gardeners to carry the machine, which increases the work intensity of gardeners. At the same time, when spraying with the whitening rod, the paint on the tree trunk will be uneven, which affects the protection of the paint on the tree trunk.

[0005] At the same time, other tree trunk whitening devices have appeared on the market. For example, in the document with application number CN201711065512.6, a tree trunk whitening machine for landscaping is disclosed, the device includes a cart, a support plate is connected to the cart, the support plate is provided with an up and down moving device, the up and down moving device is connected to a horizontal plate, and a whitening device is provided on the left side of the horizontal plate. Although the device can spray the whitening agent on the tree trunk through the liquid spraying device, the whitening agent can be evenly applied by moving the whitening device up and down through the up and down moving device, thereby achieving the effect of reducing the labor intensity of workers, increasing the whitening speed, and being easy to use and simple to operate. However, in the garden, the thickness of the tree trunks is inconsistent, and the structure of the whitening device in the device is fixed, and thus cannot be adjusted according to the diameter of the tree trunk. That is, for the tree trunks in the garden whose diameter is larger than the diameter of the spraying device, the trunk spraying work cannot be carried out, and for the tree trunks in the garden whose diameter is smaller than the diameter of the spraying device, the spraying will not be uniform.
