Wood sampling device

Abstract

The present invention relates to a wood sampling device, which comprises: a working head, which comprises a working head main body, wherein the working head main body is provided with an accommodatingspace having an inlet and an outlet, the working head main body is further provided with a chopper and a wood inserting body, which are arranged away from the inlet and the outlet of the accommodating space, the wood inserting body being provided with a sampling channel penetrating through the wood inserting body in the inserting direction of the wood inserting body, and the sampling channel being in butt joint with the inlet of the accommodating space; and an ejection device which comprises an ejection piece, wherein the ejection piece can be at least partially inserted into the sampling channel of the wood inserting body so as to eject a sample in the sampling channel to the accommodating space. When the wood sampling device is used for sampling, large heat cannot be generated due to friction, so that the wood structure of wood cannot be damaged, the activity of parasites, fungi, bacteria and the like on the wood cannot be influenced, and the accuracy of experimental results cannotbe influenced. In addition, a standby battery does not need to be carried, carrying is convenient, and the phenomenon of work interruption caused by electricity exhaustion can be avoided.

Description

technical field [0001] The invention relates to the field of wood sampling, in particular to a wood sampling device. Background technique [0002] In order to achieve theoretical research on wood or parasites, fungi and bacteria on wood, it is often necessary to sample wood. For example, pine xylophilus disease, one of the major international quarantine diseases, can cause the devastating death of pine trees and seriously threaten my country's forestry and ecological security. Specifically, the resin secretion of pine trees infected with pine wood nematode gradually decreases, the needles gradually turn reddish brown, the plants wilt, and finally the whole plant dies. Pine xylophilus disease is a complex disease system formed by the interweaving of multiple factors such as pine xylophilus, host plants, vector insects, associated fungi and bacteria, economic logistics activities, and environmental factors. The complexity of the disease system and the concealment of pine xyl...

Problems solved by technology

However, due to the high rotation speed of the output end of the electric drill, it is easy to generate a large amount of heat due to friction, destroying the wood structure of the sampled wood, and / or affecting the activity of parasites, fungi and bacteria on the sampled wood, thereby affecting the experimental results In addition, due to the large power consumption of electric drills, more spare batteries need to be carried during sampling, which is inconvenient to carry and prone to interruption of sampling work due to power exhaustion
