Description

Portable municipal garden maintenance is with trunk whitewash device

Technical Field

The invention relates to the technical field of municipal garden maintenance, in particular to a portable trunk whitewashing device for municipal garden maintenance.

Background

When seasons change, trees need to be manually whitewashed, so that the trees are protected from insect attack, and the trees are also kept warm in winter, the existing whitewashing operation mainly comprises two modes, namely manual painting and machine painting, and the defects and problems of the two modes are described as follows:

1. manually operated

The labor cost is high, the operation efficiency is low, the coating is corrosive to people, the soil at the root of the tree is polluted, the operation material is wasted about three cost, and a lot of the material directly flows to the ground along the tree trunk.

2. Machine operation

At present, a whitewashing machine which can adapt to all use conditions does not exist, and the existing equipment has a plurality of problems, so that the whitewashing machine cannot be popularized and used all the time, and the whitewashing machine is specifically as follows:

(1) the machine operation generally uses a nozzle spraying mode, but the spraying mode easily causes nozzle blockage due to the condition of spraying materials (comprising materials such as salt, quicklime and the like, and the proportion of different areas can be different according to the condition), and the spraying thickness is not good by manual operation.

(2) The device can not completely adapt to the use requirements of trees with different thicknesses, and only can operate trees within a certain thickness range.

(3) The trunk is not straight, many have some or very large curvature, and the machine equipment cannot be used in the face of this.

(4) The trunk and ground are not all in a vertical geometry, and many trunks are inclined, rendering the device unusable.

(5) In order to ensure the spraying thickness of the tree trunk, excessive spraying is easy to occur, so that the waste of liquid medicine materials is caused, and meanwhile, the liquid medicine materials flow to the ground along the tree trunk, so that the soil at the root of the tree is polluted.

(6) A liquid medicine storage tank, and a mixture sedimentation condition.

(7) The manner of using the spray nozzle easily causes air pollution, similar to a painting operation. The sprayed liquid in the pharmaceutical industry is easy to fly into the air under the action of pressure and collision, particularly, when the liquid is operated in urban areas, most of trees on two sides of a road are parked by automobiles, and the surrounding automobiles and pedestrians are easily polluted.

Therefore, a portable trunk whitewashing device for municipal garden maintenance is provided for solving all the problems.
