A manually operated tree trunk whitening device

Abstract

The invention relates to the field of garden landscaping equipment, in particular to a trunk whitening robot. The trunk whitening robot comprises a medicine box, a coating device, and an accumulator and a medicine pump positioned at the bottom of the medicine box; the coating device includes a handle rod, a U-shaped frame, coating cloth, a spring pipe and an extension rod; the U-shaped frame is positioned at one end of the handle rod; a transverse shaft is mounted at the top of the U-shaped frame; two spherical joints are slidingly mounted on the transverse shaft; two concentric steel rings are respectively arranged at the outer peripheries of the two spherical joints; the coating cloth annularly connected end to end is arranged between the steel rings; the spring pipe is positioned above the U-shaped frame; the extension rod is slidingly mounted in the spring pipe; a brush base is arranged at the end part of the extension rod; a brush is arranged on the brush base; structures similar to that above the U-shaped frame are symmetrically arranged below the U-shaped frame; but the distinguishing is that the brush base positioned on the upper side is a cavity; and a water outlet is formed in the brush base. The trunk whitening robot can work in complex terrain, performs the coating whitening for trunks with wider diameter range, and is convenient to carry and use.

Description

technical field [0001] The invention relates to the field of landscaping equipment, in particular to a manually operated tree trunk whitening device. Background technique [0002] The trunks are painted white to prevent pests and diseases, delay tree germination, and avoid sunburn hazards. In continental climate areas with severe sunshine and temperature changes, white coating can reduce the absorption of solar radiant heat by the aboveground parts of trees, thereby delaying the germination period of buds. [0003] Whitening the trunk has the following effects: [0004] 1. Sterilize, prevent bacterial infection, and accelerate wound healing. [0005] 2. Kill insects and prevent insects. Kill overwintering eggs and borers in the bark. Because pests generally like black, dirty places, they don't like white, clean places. Trunk has coated snow-white lime water, and the insect in soil just dare not climb to make trouble on tree along trunk, still can prevent bark from being...

AI Technical Summary

Problems solved by technology

[0008] In the prior art, there are multiple trunks to be painted white, although they all adopt mechanized equipment to paint white, they can only work in places with good road conditions, and can only use artificial white paint for places with bad road conditions. Among the whitening equipment, there is no better equipment that can adapt to a more complex geographical environment, and the whitening liquid is not easy to carry, making the whitening work slow and time-consuming
