Description

Technical Field

[0001] The utility model belongs to the technical field of tree removal equipment in non-cultivated land fields such as railways, highways and power sites, and specifically relates to a tree removal and pesticide application tool for injecting medicine into roots. Background Art

[0002] We call the trees and shrubs that grow wantonly in inappropriate locations in non-cultivated areas such as railways, highways, and power plants miscellaneous trees. Miscellaneous trees will block railway signal lights and highway warning signs, threatening driving safety; block photovoltaic panels, forming a "hot spot effect" and affecting power generation efficiency; occupy power access roads, hindering maintenance workers from entering the site for maintenance and construction, etc., which are highly harmful and difficult to prevent and control. In order to solve the problem of tree removal in non-cultivated land, manual felling and spraying of chemicals are currently the main measures. Manual tree removal using tools such as machetes, axes, and saws not only makes workers tired and has a large workload, but also has low work efficiency and high danger, resulting in high labor costs, low work efficiency and low economic efficiency. The use of electric saws or large instruments, such as tree removal technologies, not only requires the provision of electricity or fuel, but also increases the risk factor and is inconvenient to move and transport, which will increase the cost, and the tree roots cannot be completely removed. It will also cause the miscellaneous trees to turn green again, increasing the workload and cost of tree removal. If the roots are manually dug out, the area of ​​damage to the ground caused by the pit is large, which is easy to aggravate soil erosion. Furthermore, the spraying of chemical agents is mainly carried out on the leaves and branches of the above-ground part. The chemical agents sprayed on the leaves and branches have little effect on the roots of the miscellaneous trees, and new branches will grow again from the roots after the plants die, which cannot be completely killed; at the same time, the spraying of agents will cause harm to places other than the target tree species, and it is easy to have an impact on the surrounding environment. There is no tool in the prior art that can be used to remove trees by applying drugs from the roots. The existing tree removal technology generally uses old-fashioned tools such as machetes, axes, saws, etc. to cut trees manually. In addition, there are some new technologies for tree removal, such as electric saws, some large machines, etc. In addition, the tree removal effect can be achieved by spraying agents on the leaves. These tree removal methods are likely to cause safety problems for tree removers, increase workload, low efficiency, cause economic losses and environmental damage, etc. There is an urgent need to develop a tree removal and drug application tool for injecting drugs at the roots, which is simple to operate, easy to use, improves work efficiency, reduces costs, avoids drug damage to surrounding plants caused by drift of drugs when spraying the crown, and is economically and environmentally friendly.
