Description

Technical Field

[0001] The utility model belongs to the technical field of sampling devices, and particularly relates to a trunk sampling device for tree pest and disease investigation. Background Art

[0002] Forest tree diseases are a process in which various adverse factors in the environment cause a series of abnormal changes in the physiological functions, anatomical structures, and external forms of forest trees, affecting their growth, development, or survival and causing certain economic losses. When investigating tree pests and diseases, it is necessary to sample the tree trunk and then inspect the samples, so trunk sampling equipment is required. Since the eggs of pests mostly inhabit the folds of the tree trunk epidermis, only the epidermis of the tree trunk needs to be sampled during sampling.

[0003] In the existing sampling devices, usually a peeling knife is directly used to peel the epidermis in a certain area of the tree trunk. If directly peeled with a peeling knife, it is difficult to control the sampling area, and it is easy to exceed the specified area and peel off the intact bark that has not been damaged by pests together, causing damage to the tree.

[0004] In view of this, the inventor of the present case has conducted in-depth research on the above-mentioned defects in the prior art, and thus this case has been created. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a trunk sampling device for tree pest and disease investigation, which can prevent exceeding the specified area when sampling the tree trunk epidermis and causing damage to the tree trunk.

[0006] To achieve the above technical purpose, the technical scheme adopted by the utility model is as follows:

[0007] A trunk sampling device for tree pest and disease investigation includes two groups of horizontally engraved components arranged in parallel, two groups of vertically engraved components arranged in parallel, and an installation frame for installing the horizontally engraved components and the vertically engraved components; the two groups of horizontally engraved components are distributed up and down, and the two groups of vertically engraved components are distributed left and right; the installation frame includes two arc-shaped cross beams arranged up and down and multiple support columns connected between the two arc-shaped cross beams; the two groups of horizontally engraved components are slidably installed on the support columns, and the two groups of vertically engraved components are slidably installed on the arc-shaped cross beams.

[0008] Furthermore, the transverse engraving assembly includes an arc-shaped blade and an arc-shaped handle. A plurality of first sliders are formed on the outer side of the arc-shaped handle and are slidably connected to the inner side of the support column. A first sliding groove for the first slider to slide is formed on the support column. An adjusting screw for driving the two sets of transverse engraving assemblies to move away from or close to each other is further provided on one of the support columns. The arc-shaped blade can rotate back and forth along the circumferential surface of the tree trunk to engrave a corresponding area, which can adapt to tree trunks of different diameters. In addition, the distance between the upper and lower sets of transverse engraving assemblies can be adjusted by the adjusting screw, so as to adjust the size of the sampling area.

[0009] Furthermore, there are three support columns, and the three support columns are evenly spaced. The adjusting screw is rotationally connected to the first sliding groove at the middle position. A threaded hole that is threadedly engaged with the adjusting screw is formed on the first slider at the middle position. A knob is further provided at the top of the adjusting screw. Setting the adjusting screw on the support column at the middle position can make the transverse engraving assembly move more smoothly.

[0010] Furthermore, the arc-shaped blade and the arc-shaped handle are detachably connected. An installation slot is formed on the inner side wall of the arc-shaped handle, and a clamping strip that is clamped with the installation slot is formed on the arc-shaped blade. The arc-shaped handle and the clamping strip are fixed by a plurality of screws. Setting the arc-shaped blade and the arc-shaped handle in a detachably connected form can replace the arc-shaped blade when it is damaged.

[0011] Furthermore, the vertical engraving assembly includes an engraving knife, a guide rod, and a connecting member connecting the engraving knife and the guide rod. Second sliders are provided at both ends of the guide rod. Second sliding grooves that cooperate with the second sliders are formed on the inner side walls of the two arc-shaped cross beams. The second sliding grooves are arc-shaped, and the guide rod is rotatably connected to the second slider. The connecting member includes a sliding sleeve slidably sleeved on the guide rod and a mounting sleeve for mounting the engraving knife. A connecting sleeve is formed on the outer side wall of the sliding sleeve, and a connecting shaft that is rotationally engaged with the connecting sleeve is formed on the side wall of the mounting sleeve. By slidably mounting the guide rod on the arc-shaped cross beam, the distance between the two vertical engraving assemblies can be adjusted, so as to adjust the size of the sampling area.

[0012] Furthermore, the engraving knife includes a circular blade and a mounting handle. The circular blade is rotationally connected to the end of the mounting handle, and the mounting handle is slidably mounted in the mounting sleeve. Sliding the mounting handle in the mounting sleeve can adjust the position of the engraving knife to adapt to tree trunks of different diameters.

[0013] Furthermore, handles are provided on the outer side walls of all three support columns. Providing handles on the support columns facilitates the control of the entire device.

[0014] After adopting the above structure, a trunk sampling device for tree pest and disease investigation involved in the present utility model, compared with the prior art, by arranging two sets of horizontally scribing components distributed up and down and two sets of vertically scribing components distributed left and right on the installation frame, before using a peeling knife for peeling and sampling, the staff first use the horizontally scribing components and the vertically scribing components to scribe out the sampling area and isolate it from other epidermis. In this way, when peeling and sampling subsequently, it will not exceed the designated area and will not damage other epidermis of the tree trunk. Brief Description of the Drawings
