Abstract
The utility model provides a small growth cone. The small growth cone comprises a cone handle, a cone body and a cone head, wherein the cone head is fixedly connected to one end of the cone body; a groove is formed in the cone head; the cone handle vertically penetrates through the cone body and is fixed at the other end of the cone body. The small growth cone provided by the utility model can be used for collecting a tree core of a small tree with slight damage to the tree.
Description
Technical field
The utility model relates to a kind of small-sized growth cone.
Background technology
Forestry research often need to carry out sampling and measuring to trees, particularly to tree core while studying, making trees can maintenance growth in the situation that, often uses growth cone to tree core sampling.This diameter of tree core that the growth cone using at present gathers is larger, while gathering the tree core of small-sized trees, trees is had to certain injury.In addition, because the diameter of sampling is large, so can not gather miniature tree core, also be unsuitable for regularly on same trees, gathering, so, can not be according to the season of growth of trees, regularly multi collect, with the tree core of a trees, is unfavorable for carrying out the research with the radially seasonal growth change rule of a trees.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of small-sized growth cone that gathers miniature tree core, can realize the collection to minimal tree ebon core, little to trees injury.
The object of the invention is to be achieved through the following technical solutions:
A growth cone, comprises taper shank and centrum, and described small-sized growth cone also comprises: conehead, and described conehead is fixedly connected on one end of described centrum, on described conehead, is provided with groove; Described taper shank vertically passes described centrum, is fixed on the other end of described centrum; On described centrum, have screw, bolt is fixed on described conehead one end of described centrum through screw.
Optionally, described centrum is hollow.
Optionally, the width of described groove is: 4mm, and the diameter of described conehead is 5mm, the length of described conehead is 20mm.
Optionally, the length of described centrum is 100mm, diameter 15mm, wall thickness 2mm.
Optionally, described taper shank is 20mm in the length of described centrum one side.
During use, two hold the taper shank on centrum both sides, and conehead, perpendicular to trunk, is firmly penetrated conehead in trunk, and conehead enters trunk, and the batten that enters groove is removed, and realize the collection to small-sized number tree core.Owing to adopting conehead to be fixed on one end of centrum, a groove is directly set on conehead, the diameter of conehead and length can design as required, especially be applicable to the collection of small-sized seeds tree core, do not need to pierce trunk very dark, do not injure trees, can also obtain as required trees seasonal growth and change numerical value.The utility model simple structure, durable, volume is little is convenient for carrying, and with respect to growth cone of the prior art, the utility model is more suitable for the collection of small-sized seeds tree core and the collection of the seasonal growth change data of trunk.
Accompanying drawing explanation
Fig. 1 is the small-sized growth longitdinal cross-section diagram that the utility model provides.
Embodiment
The utility model discloses a kind of small-sized growth cone, as shown in Figure 1, comprises taper shank 2 and centrum 1, conehead 3, and conehead 3 is fixedly connected on one end of centrum 1, is provided with groove 4 on conehead 3; The vertical other end that passes centrum 1, is fixed on centrum 1 of taper shank 2.
It is upper that conehead can directly be welded on centrum, or conehead and centrum are integrated while producing.
For the convenient tree core taking out in groove, the utility model arranges the connected mode that conehead and centrum can separate.Centrum 1 is hollow, has screw 5 on centrum, and bolt is fixed on conehead 3 one end of centrum 1 through screw 5.Twist off bolt, can take off conehead, pour out the tree core in groove.
The width of groove 4 is: 4mm, and the diameter of conehead 3 is 5mm, the length of conehead 3 is 20mm.
The length of centrum 1 is 100mm, diameter 15mm, wall thickness 2mm.
The present embodiment has provided the concrete size of groove, centrum, taper shank, conehead, this is the concrete structure that the present embodiment provides, in the concrete process of implementing, the concrete size of groove, centrum, taper shank, conehead is not limited to above-described embodiment, can specifically select size according to the specification of growth cone, the present embodiment does not limit this.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
