Description
Technical field
The present invention relates to a kind of trees corer, especially a kind of tree core extraction element.
Background technology
Growth cone is forestry research trees, is sampled measurement, the most commonly used instrument, is not destroying trees normal growth
In the case of drill through trees wooden core sample, analyze and determine arboreal growth speed, tree age, the solid degree of arboreal growth and battalion
The related subject such as material migration is supported, is that forestry circle carries out widely used instrument when arboreal growth investigation, analysis.
There are problems with use for current handheld formula growth cone：
Time-consuming and laborious in trees drilling operation, when beginning, pierces shallower, and resistance is smaller, with the increase for piercing depth, resistance
Power gradually increases, and continuous sampling labor intensity is big；Gait of march is uneven, and limited personnel cannot uniformly and stably export energy,
And during tree core extraction institute, it is also necessary to rotary drilling-head handle, it is hand-off, cause to accelerate, slow down, pause so that piercing traveling speed
Degree is different, and acquired sample will necessarily be made also uneven；In drilling operation, due to height, personnel's fatigue, operating error, is bored
Bar is difficult to holding level.
Patent CN102225557A Rechargeable lithium battery half-type electric tree growth cones, motor are carried by rechargeable lithium battery
Power supply source, coring bit is driven by motor, and the rear of the growth cone shell, is fixed with level meter and horizontal hand grip；It can be achieved three
Shelves formula speed change, is pierced trees xylem by drill bit with reference to triple thread, two line screw thread drill bits, is powered using rechargeable lithium battery,
It is applicable to various crowd.
The invention provides power by motor of rechargeable battery, and motor during the work time, produces vibrations, leads to not accurate
Keep drilling rod horizontal, can influence the effect of coring, motor power consumption is big, it is necessary to be equipped with battery, is unfavorable for field long-term work.
In view of the above problems, ad hoc count clamp arm to fix coring bit, the machinery such as worm gear, worm screw, helical gear is utilized to fill
Put, save manpower, stablize output and turn degree, tree core extraction is preferably realized, in order to observation analysis arboreal growth, development, nutrition
The characteristics such as migration.
The content of the invention
The technical assignment of the present invention is to be directed to above the deficiencies in the prior art, and provides a kind of tree core extraction element.
The technical solution adopted by the present invention to solve the technical problems is：One kind tree core extraction element, including for being driven
Gear-box, wherein being equipped with rocking arm at the gear-box rear, hollow thief rod is equipped with the gear-box front end, described
The both sides of gear-box front end are hinged with clamp arm, and threaded sleeve is hinged with the clamp arm, in the threaded sleeve
Equipped with clamping screw, clamping screw both ends screw thread it is oppositely oriented, be equipped with fixed tooth, first rocking arm in the inner side of the clamp arm
It is connected by the travelling gear in gear-box with thief rod, then allows the trunk of sampling between two clamp arms, Ran Houtong
Rotation clamping screw is crossed so that clamp arm is clamped on trunk, controls thief rod to retreat finally by rocking arm is rotated, so that complete
Into sampling work.
Further improve：In order to strengthen clamping effect of the clamping limb to trunk, the phenomenon having skidded is placed, therefore in institute
The front end for stating clamp arm is hinged with auxiliary clamp arm, and the front end of the auxiliary clamp arm is hinged by active pin shaft.
Further improve：Hollow boring bit is equipped with the front end of the thief rod.
Further improve：In order to meet the sampling demand to different-diameter trunk, therefore the outside in the gear-box
Equipped with some card slots, the thief rod of different length is not placed with the card slot.
Advantages of the present invention：It is the configuration of the present invention is simple, easy to operate, with two clamp arms, extraction equipment is fixed on tree
Dry front end, two clamp arms are controlled by screw rod respectively, are adapted to different trunk diameters；Utilize worm screw, turbine and helical teeth
Mechanism is taken turns, can substantially reduce and drill through the amount of labour；Under the action of thief rod rotary force, constantly advance to trunk inside, obtain tree core
Sample, is very suitable for field long-term work.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the top view of Fig. 1 of the present invention.
Fig. 3 is the structure diagram of present invention clamping maximum gauge trunk.
Embodiment
The present invention is described below with reference to Figure of description.
As shown in the figure, a kind of tree core extraction element, including the gear-box 2 for transmission, wherein at 2 rear of gear-box
Equipped with rocking arm 1, hollow thief rod 3 is equipped with 2 front end of gear-box, is hinged with the both sides of 2 front end of gear-box
Clamp arm 6, threaded sleeve 5 is hinged with the clamp arm 6, and clamping screw 4 is equipped with the threaded sleeve 5, clamps spiral shell
4 both ends screw thread of bar it is oppositely oriented, be equipped with fixed tooth 61 in the inner side of the clamp arm 6, rocking arm 1 first passes through in gear-box 2
Travelling gear be connected with thief rod 3, then allow the trunk 7 of sampling between two clamp arms 6, then pass through to rotate and clamp
Screw rod 4 causes clamp arm 6 to be clamped on trunk 7, controls thief rod 3 to retreat finally by rocking arm 1 is rotated, so as to complete to sample
Work.
In order to strengthen clamping effect of the clamping limb 6 to trunk 7, the phenomenon of skidding is prevented, therefore in the clamp arm 6
Front end be hinged with auxiliary clamp arm 8, the front end of the auxiliary clamp arm 8 is hinged by active pin shaft 81, before the thief rod 3
End is equipped with hollow boring bit, and in order to meet the sampling demand to different-diameter trunk 7, therefore the outside in the gear-box 2 is set
There are some card slots, the thief rod of different length is placed with the card slot.
Its operation principle is：The active pin shaft 81 for aiding in 8 front end of clamp arm is removed first during use, allows trunk 7 positioned at folder
Tight arm 6 and the centre of auxiliary clamp arm 8, then the front end for aiding in clamp arm 8 is connected, pass through at this time by active pin shaft 881
Clamping screw 4 is rotated to adjust the angle of the opening of clamp arm 6 so that clamp arm 6 clamps trunk 7, finally rotates 1 band of rocking arm
Dynamic thief rod 3 rotates, so as to complete sampling work.
The foregoing is merely the embodiment of the present invention, is not intended to limit the scope of the invention, every to utilize this hair
The equivalent structure or equivalent flow shift that bright specification and accompanying drawing content are made, is directly or indirectly used in other relevant skills
Art field, is included within the scope of the present invention.
