Description

Tree-removing auxiliary girdling driller Technical Field The utility model belongs to the technical field of auxiliary equipment for tree removal and pesticide application, and particularly relates to an annular cutting driller for tree removal. Background Bark refers to all tissues except for the vascular cambium of the old tree trunk, and is a protective structure on the periphery of the tree trunk. The bark has the functions of preventing cold and heatstroke, preventing diseases and insect pests, and transporting nutrients, and can transport the nutrients produced by photosynthesis of leaves to roots and other organs. Inside the bark, a layer of tissue called phloem, is arranged a line of pipes, which transport the nutrients that the tree survives, which is an essential part of the tree's survival. Except bark, the inside is in turn cambium, edge material, heart wood and marrow, wherein cambium is very thin, is the growth part of trunk, all other cells come from the cambium, the edge material is used for conveying water from root to all parts of tree body, the cambium is usually lighter than heart wood, the heart wood is old edge material, the two are called wood parts together, and marrow genus primary tissue is positioned in the center of the wood parts. It follows that survival and growth of trees are greatly related to the constituent parts of the trunk, and destruction and application of drugs from the constituent parts of the trunk can accelerate the tree removal efficiency. The existing tree removing method for non-cultivated land uses tools such as hacking knife, axe, electric saw and the like to cut down the tree manually, or sprays chemical agent after peeling off the bark to achieve the aim of killing the tree. The existing bark stripping tool is a fruit tree bark scraper which scrapes bark one by one, so that repeated scraping is time-consuming and labor-consuming, or a sickle-like cutter which firstly transversely cuts a knife on a trunk, then transversely cuts a knife at an upward or downward position, then longitudinally cuts a knife from top to bottom between cutting marks of the two knives, and reaches xylem, then inserts a knife bulge into a longitudinal seam to lift up and down and left and right, and the bark is pried up, and finally strips the bark. The two methods can be used for peeling bark, but the peeling surfaces have the problems of different sizes and irregular shapes, so that the medicament is not accurate in dosage and is easy to waste when the medicament is applied subsequently, the operation is inconvenient, and the time and the labor are wasted, and the positions and the sizes of scraping or girdling are required to be paid attention. Therefore, it is necessary to develop a tool for assisting in removing the pesticide from the tree, which can accurately determine the stripping position and control the size of the pesticide application hole, so as to improve the pesticide utilization rate of the pesticide for removing the tree, and further improve the tree removing efficiency. Disclosure of utility model In order to solve the technical problems, the utility model provides a trepanning drill assisted by removing trees, which is used as a tool for assisting the application of the trepanning. In order to achieve the above purpose, the utility model adopts the following technical scheme: The utility model provides a remove supplementary girdling driller of tree, it includes two curved tool bit, handle, motor and drill bit, wherein two curved tool bit detachable connects in the one end of handle, and the motor is located inside the other end of handle, and drill bit detachable connects on the motor shaft of motor, and the motor shaft can drive the drill bit and rotate, and two curved tool bit includes two curved blades and tool bit cutting ferrule, and curved blade is fixed to be located the one end of tool bit cutting ferrule, and the connection handle can be dismantled to the other end of tool bit cutting ferrule, and curved blade's cutting edge is seted up in curved inboard.
