Background technology
Forestry research often need be carried out sampling and measuring to trees, and growth cone is an instrument the most commonly used, it is by drilling through trees reel sample, under the situation of not destroying the trees normal growth, thereby analyzing relevant subjects such as determining arboreal growth speed, trees age, the solid degree of arboreal growth and nutriment migration, is that the arboreal growth investigation is carried out in forestry circle, widely used instrument when analyzing.
At present, existing growth cone is mainly Sweden's growth cone, and its carbon steel quality is better, and volume is less, and is easy to carry in the process of the test in the open air, uses morely, but in use there is following problem in this growth cone:
(1) wastes time and energy in the trees drilling operation.Though at unlike material trees respective design different screw-type drill bits, before drilling through trees, need firmly drill bit to be supported in the test tree bast portion, even otherwise firmly also can't make drill bit enter the xylem of trees under the situation.After drill bit entered the trees xylem, firmly turnbarrel further entered the trees xylem to impel drill bit, this work is effort quite, generally needs the man to finish this work, and in the turnbarrel process, must keep the drill bit level, not only require great effort but also time-consuming in the trees drilling operation.
(2) the tree core takes out comparatively difficulty.Though conventional growth cone is furnished with special corer, in actual mechanical process, get core and acquire a certain degree of difficulty, and be careful in the process of getting cautiously, otherwise the tree core is broken, it is also comparatively time-consuming to get tree core process.
Summary of the invention
The purpose of this invention is to provide the electronic arboreal growth awl of a kind of chargeable lithium cell Hough formula.The electronic arboreal growth of chargeable lithium cell Hough formula of the present invention awl can overcome existing technological deficiency, can accomplish in the trees drilling operation in the process of rotary coring, keeps the level of drill bit, and can accomplish laborsavingly to save time again; Can also more easily drill bit be taken out from the trees xylem; The tree core takes out also comparatively convenient and easy; Prioritization scheme of the present invention can be at the forest type of different hardness, and it is reliable more and convenient to adopt different speed stages to use.
The technical scheme of finishing the foregoing invention task is that the electronic arboreal growth awl of a kind of chargeable lithium cell Hough formula is provided with coring bit (abbreviation drill bit), it is characterized in that described coring bit adopts the coring bit of Hough formula structure; This coring bit is by protection head, connection ratch and connector, with the rotor fixed connection; Described motor provides power supply by chargeable lithium cell; Rear at this electronic arboreal growth awl shell is fixed with level meter and horizontal hand grip; This level meter and horizontal hand grip and coring bit be arranged in parallel.
In other words, the present invention changes traditional arboreal growth awl into the electrically operated while, has also adopted following technical measures:
Described coring bit adopts the coring bit of Hough formula structure;
Rear at this electronic arboreal growth awl shell is fixed with level meter and horizontal hand grip; This level meter and horizontal hand grip and coring bit be arranged in parallel.
Above measure guaranteed in the process of rotary coring, keeps the level of drill bit, and can accomplish laborsavingly to save time again; Can also more easily drill bit be taken out from the trees xylem; The tree core takes out also comparatively convenient and easy.
Prioritization scheme of the present invention is: be connected with speed changer and varying speed switch (or being called speed regulator and speed-regulating switch) on the described rotor, make this rotor become the three class gear shift rotor.
After adopting above structure, compared with prior art, the invention has the advantages that: it is easy to get the tree core from Hough formula drill bit, time saving and energy saving, and under the effect of double-shift type speed-varying rotor, the exportable two kinds of speed of motor, thereby driving drill bit produces fast, slow two kinds of different velocities of rotation, in conjunction with triple thread, two line screw thread drill bits, can easily bit drills be gone into the trees xylem, and, electronic growth cone is used in the place that non-transformer conditioned disjunction power line can't touch owing to use chargeable lithium cell, and electronic growth cone is simple to operate, is applicable to various crowd.The present invention is directed to dissimilar forests and have different materials, density of wood differs greatly between different seeds, and when obtaining tree core product, trees generally are in growth conditions, xylem contains certain moisture, drill bit can difficultly take out after entering the tree body, so electronic growth cone of Hough formula of the present invention, adopted fast, slow, reverse gear design, have three gears, quick gear rotor maximum speed 5000 commentaries on classics/min, gear rotor maximum speed is 3000 commentaries on classics/min at a slow speed, the reverse gear rotating speed is with the gear rotating speed is identical at a slow speed.Fast gear can be at the big forest type of hardness, and gear can be at the less forest type of hardness at a slow speed, and reverse gear can help drill bit to take out from the trees xylem smoothly.
