Novel whitewashing device for tree trunk in winter

Abstract

The invention relates to a novel whitewashing device for a tree trunk in the winter. A mechanism track is arranged on a vertical supporting rod, and an upper supporting arm and a lower supporting arm are respectively arranged on the mechanism track, and are connected with a motor through belts respectively; the upper supporting arm and the lower supporting arm are irregularly hexagonal, and double-hinged sliding rod supports are arranged at four corners formed by intersecting of five sides of the upper supporting arm; double-hinged sliding rod supports are arranged at four corners formed by intersecting of five sides of the lower supporting arm; a double-hinged sliding rod is arranged on each double-hinged sliding rod support; each double-hinged sliding rod is connected with two connecting rods; the two adjacent connecting rods of each double-hinged sliding rod are X-shaped to form five X-shaped rotation pairs; a sprayer is arranged at the position of the center of each of the five X-shaped rotation pairs; the sprayers are adjacently connected with a high-pressure plunger pump through a pipe; and the pipe is curled up in an automatic pipe winding wheel. The novel whitewashing device for the tree trunk in the winter is simple in structure, reasonable in design and high in practicality; and the distance between the upper supporting arm and the lower supporting arm is adjusted to adjust the diameter of an inscribed cylinder of a regular pentagonal prism.

Description

technical field [0001] The invention belongs to the technical field of forestry tools, in particular to a novel winter tree trunk whitening device. Background technique [0002] The whitening of the trunk refers to the fact that the trunk is painted with a layer of white liquid by workers. After the trunk is put on the white dress made of lime water, it can reflect back 40-70% of the sunlight. In this way, the heat absorption is reduced, and the trunk will not freeze and crack due to the huge temperature difference between day and night. It also has the functions of sterilization and insect repellent. . [0003] At present, the whitening of tree trunks in municipal engineering usually adopts the method of manual whitening, but after investigation and investigation of manual whitening work, it is found that the main problems can be summarized as follows: [0004] 1. Manual whitening is inefficient. The whitening of trees requires that lime slurry be evenly applied to all s...

AI Technical Summary

Problems solved by technology

[0004] 1. Manual whitening is inefficient

The whitening of trees requires that lime slurry be evenly applied to all sides of the tree in order to achieve the effect of whitening. Workers need to bend over when working; moreover, the tree is cylindrical, and workers need to move constantly to paint a tree well. For the sake of beauty, it is required that the whitening height of each tree is basically the same, and the corresponding effect can only be achieved after preliminary measurement manually, which greatly affects the work efficiency

[0005] 2. The quality of white coating is uneven

The quality of the whitening effect affects the normal growth of trees. When workers paint white, once they want to increase the work speed, the effect will be very poor, because the surface layer of the white paint is uneven and the effect is not good.

At the same time, the lime slurry configured is very viscous and has poor fluidity, so it is difficult to enter the gaps of trees and cannot really play a role in preventing insects.

[0006] 3. The preparation of whitening agent is harmful to the human body

[0007] At present, the research and development of this type of machine in the market is not mature enough, and it is far from meeting the application needs of the market. The most prominent thing is that it has not completely solved the urgent and practical problems such as work efficiency.
