Embodiment Construction

[0018] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0019] Such as Figure 1~3 As shown, the adjustable instant package tree skin sampler is composed of an adjustable cutter head group, a handle, a rotating bearing, a rotatable handle, a fixed clip and a sample packaging bag.

[0020] Such as figure 2 and image 3 As shown, the blade part in the adjustable cutter head group is fixed and cannot be moved. Its material is stainless steel, and the blade length is 60mm; while the lower bracket can move up and down, the distance between it and the blade is 13mm, and the bracket width is 20mm. There is a row of teeth 15 with a vertical pitch of 1mm in the lower bracket, which is used to connect with the gear 10 on the upper end of the rolling bearing. Four small springs are installed at the four corners of the lower bracket, so that the bracket has recovery ability, and the height difference between the c...

Abstract

The invention relates to an adjustable real-time encapsulation tree skin sampler, in particular to a manual device for peeling off skins of trees or round logs. The adjustable real-time encapsulation tree skin sampler features portability, single-person operation, capacity of standardizing collection process of tree skins, adjusting the thickness of the sample needed, encapsulating the collected sample into a sampling device in real time and preventing the sample after sampling from being polluted, and is mainly applied to tree skin sampling in environmental monitoring and scientific researchprocesses. The device is provided with an adjustable tool head pack, a handle, a rotatable bearing, a rotatable handle, a first fixing toggle clip, a second fixing toggle clip and a sampling container; the adjustable tool head pack is connected with the handle in a detachable way, the first fixing toggle clip is fixed at a support at the middle-lower part of the adjustable tool head pack, the second fixing toggle clip is arranged at the top of the adjustable tool head pack, a sample rolling-out channel is arranged between the first adjustable toggle clip and the second toggle clip, and the sampling container is arranged between a cutting blade and a support of the adjustable tool head pack.

Description

technical field [0001] The present invention relates to a manual device for peeling bark from trees or logs, and more particularly to an adjustable instant package tree bark sampler. Background technique [0002] With the aggravation of environmental pollution, the evaluation of the degree of environmental pollution has been paid more and more attention. Compared with the current active air sampling device driven by power, as a passive air pollutant sampling medium - "tree skin", because it can enrich the particulate and gaseous pollutants and Objectively reflecting the long-term "average" level of air pollution, and the advantages of green and low cost, the role played in environmental monitoring has gradually been recognized and accepted by people. However, there is no special tool for tree skin collection at present. Most environmental monitoring departments and scientific research institutions just use sharp tools to peel off the tree skin when collecting tree skin, and...
