Semi-automatic tree whitewash machine

Abstract

The invention discloses a semi-automatic tree whitewash machine. The problems that in the prior art, pesticide liquid waste is serious, pesticide liquid generates sediment after long-time standing, and operation is complex are solved. During spraying, a stirring part continuously operates, the effect of pesticide liquid is kept, a recycling part automatically recycles surplus pesticide liquid, the production efficiency is greatly improved, labor cost is reduced, land salinization is relieved, and the environment is protected. According to the technical scheme, the semi-automatic tree whitewash machine comprises a spraying mechanism. The spraying mechanism comprises a spraying sleeve, a sprayer head is arranged in the spraying sleeve, and anti-splash shielding devices are arranged at the top end and the bottom end of the spraying sleeve in a matched mode and used for shielding splashing spraying liquid into the spraying sleeve during spraying. The spraying mechanism is connected with a transmission mechanism. The transmission mechanism comprises a rotation driving assembly which drives the spraying mechanism to realize rotation. The spraying mechanism further communicates with a liquid supply and recycling mechanism which provides spraying liquid for the spraying mechanism and meanwhile recycles surplus spraying liquid at the spraying mechanism.

Description

technical field [0001] The invention relates to the technical field of garden machinery, in particular to a semi-automatic tree whitening machine. Background technique [0002] In winter, the whitewashing of trees is an essential work for garden protection. [0003] The purposes of tree whitening include: (1) tree whitening can effectively delay the budding and flowering period of trees, and prevent the harm of frost in early spring. At the same time, trees in early spring are easy to be cracked by frost. After the trees are painted white, they can reflect most of the direct light, which can effectively prevent the trees from cracking due to temperature differences. (2) Trees painted white can protect trees from infection by germs, and can also kill overwintering fungi and germs parasitic on trunks, and also have a certain effect on accelerating tree wound healing. (3) Whitening the trees can effectively reduce the soil pests that harm the trees to climb on the trees, kill...

AI Technical Summary

Problems solved by technology

[0006] At present, traditional manual whitening has the following disadvantages: (1) Manual whitening is labor-intensive

Since the manual whitening requires the whitening workers to use a brush to dip the whitening agent and apply the whitening agent evenly on the main trunk and the base of the ground branch. The height of the whitening is preferably 1 to 1.2 meters from the ground. Barrel work, the load on the lumbar spine of the human body is extremely high, and it is harmful to the health of workers

(2) Artificial whitening has a corrosive effect on the skin of workers

Since the main component of the liquid required for whitening is quicklime, which is alkaline, it is easy to corrode the skin of the hands of the operator.

(3) The work steps of artificial whitening are complicated, the time consumed is long, and the efficiency is low

When manually whitening, it is necessary to use a brush to dip in the liquid medicine, and stir the liquid medicine while dipping in the liquid medicine. In the process of brushing the trees, it is necessary to pay attention to the degree of whitening of the trees, which is complicated to operate.

(4) Affects the appearance and corrodes the roots of trees, which can easily make the soil salinized and cause soil compaction

(5) Artificial whitening has many limitations to a certain extent

At present, although there are many design theories about whitening trees in China, there is no practical tree whitening device. Most of the whitening of trees is done manually. Manual whitening is labor-intensive and corrosive to the skin of workers. Function, the working steps are complicated, it takes a long time, the efficiency is low, it affects the appearance, and it corrodes the tree roots, causing the soil to compact the liquid medicine

The main component of the liquid required for whitening is quicklime, which is alkaline and easy to corrode the skin of the operator, posing a threat to the health of the operator

[0008] The patent document whose application number is 201120048109.4 discloses a new type of tree whitening machine. It uses a brush mechanism. The brushing force of the brush can only brush the surface of the tree. If the bark is damaged, it cannot input the bark. Internally, the insect eggs inside the bark cannot be killed; the patent document with the application number 201510554231.1 discloses a tree whitening machine, and the patent document with the application number 201520567268.3 discloses a garden tree whitening device. The whitening machine used in these two documents The mechanisms are all spray guns. The spray guns are easy to cause waste during the spraying process. The wasted liquid medicine falls into the soil around the roots of the trees, causing the soil to be partially compacted and damaging the roots. Adding baffles can prevent waste, but after all, the baffles are limited in length, and most of the liquid medicine is still sprayed into the air and falls on the soil, causing environmental pollution; the patent document with application number 201420104009.2 discloses a hand-push tree whitening Machine, the patent document with application number 200820087383.0 discloses a tree whitening machine, the patent document with application number 200820138108.7 discloses a convenient tree whitener, and the patent document with application number 201520213565.8 discloses a sprayer for tree whitening, The patent document whose application number is 201120552171.7 discloses an agricultural and forestry tree spraying machine, the patent document whose application number is 201020287196.4 discloses a tree whitening machine, and the patent document whose application number is 201620214079.2 discloses a convenient tree spraying machine. Stirring device, the medicinal liquid is turbid, and standing still for a long time will cause the liquid to settle to the bottom of the liquid storage tank, which will reduce the medicinal effect and have an adverse effect on the protection of trees; the patent document with application number 201510554231.1 discloses a portable tree whitening machine, the patent document whose application number is 201420841293.1 discloses a high-efficiency tree whitening machine, the patent document whose application number is 201420752049.8 discloses a kind of trunk whitening machine that can adapt to the position of trees, and the patent document whose application number is 200810171363.6 discloses a garden paint White machine, all the above-mentioned documents do not take into account the recycling of the redundant and wasted chemical solution in the spraying process, and the excess chemical solution will fall into the soil around the tree roots, damage the tree roots, and pollute the environment

The manual operation required by the scheme of the above literature is complicated, and the automation of the spraying process has not been realized, which prolongs the time required for the spraying work to a certain extent, and the work efficiency is low; the spraying part can only move up and down for spraying, neither forward nor backward Turn left and right so it adds a lot of limitations

[0009] To sum up, in the prior art, there is still no effective solution to the problems of serious waste of chemical solution in tree whitening machine, long-term static precipitation of chemical solution and complicated operation
