A high-density tree growth cone combination tool

Abstract

The invention discloses a high-density type tree growth cone combined tool, comprising a growth cone boosting fixing device, a high-density type tree growth cone and a growth cone sawdust cleaner, thegrowth cone boosting fixing device is detachably connected with the high-density type tree growth cone, and the high-density type tree growth cone is detachably connected with the growth cone sawdustcleaner. The high-density type tree growth cone combined tool disclosed by the invention has the advantages that a sampler embeeding groove is formed in the inner wall of a drill rod of the combinedtool, and a sampler can be completely embedded in the groove, so that the sampler can be smoothly inserted into the drill rod and completely take out a tree core; by virtue of leverage of a tool pointat the top end of a drill and the growth cone boosting fixing device, the drill can smoothly enter tree bark, and both time and labor are saved; and the growth cone sawdust cleaner can effectively clean residual sawdust in the drill rod, the drill rod is prevented from being blocked by excessive sawdust, and the sampler can beneficially take out the tree core.

Description

technical field [0001] The invention relates to the technical field of dendrochronology, in particular to a high-density tree growth cone combination tool. Background technique [0002] Tree growth cones are primarily used for sampling trees in dendrochronology studies. The currently used growth cones are mainly used for ordinary density trees in subtropical, temperate humid areas and semi-arid areas. Since the bark layer of this type of trees is relatively soft and the wood density of the trees is not high, the growth cones are easier to drill into. The core sample can be taken out relatively easily by the sampler extending into the hollow drill pipe. However, for the high-density trees or shrubs growing in the arid desert area of ​​Northwest my country, because the bark layer of the trees in this area is hard and the wood density of the trees is very high, it is difficult for the growth cone drill bit to enter the bark layer, and the core samples in the drill pipe Due to ...

Problems solved by technology

However, for the high-density trees or shrubs growing in the arid desert area of ​​Northwest my country, because the bark layer of the trees in this area is hard and the wood density of the trees is very high, it is difficult for the growth cone drill bit to enter the bark layer, and the core samples in the drill pipe Due to the high density, it is difficult for the sampler to reach in and take out a complete core sample

This problem severely affects tree-ring survey sampling by forestry surveyors in the drylands of the Northwest
