Description

Technical Field

[0001] The utility model relates to the field of forest protection sampling equipment, in particular to a sampling tool for monitoring pine wilt disease. Background Art

[0002] Pine wilt disease is a plant disease caused by a parasitic nematode called Bursaphelenchus xylophilus. Bursaphelenchus xylophilus is transmitted by insects such as Monochamus alternatus. When an infected insect host carrying Bursaphelenchus xylophilus enters a healthy pine tree, the nematodes enter through the wounds dug by the insects in the tree tissues and use the tree sap and other resources of the tree for reproduction. This will lead to the weakening and death of the tree.

[0003] Chinese Patent with the authorization announcement number CN203869896U discloses a micro tree sampling device. The product of this utility model includes a housing, a tree sampling cone and an upper cover. The housing includes a base and a sampling cone protection shell. The sampling cone protection shell is buckled on the base. Slideways are provided on both sides of the sampling cone protection shell. The button is arranged on the outer surface of the housing through a snap spring. A sampling cone is assembled in the sampling cone protection shell. The tail of the sampling cone is buckled on the groove of the base through a spring. A number of sampling conical tubes are arranged in the sampling cone. The sampling conical tubes are connected to the housing through push rods. This utility model adopts the structural form of the sampling cone protection shell, which can hide the sampling cone in the sampling equipment, and the sampling cone can be replaced with different specifications according to needs, facilitating sampling applications and improving the safety of use.

[0004] However, this device still has deficiencies: when in use, the device cannot be fixed on the tree to be sampled, so it is necessary to manually support and fix the device by hand, which increases the working intensity of the sampler to a certain extent. Summary of the Utility Model

[0010] And a fixing assembly, which is arranged on the fixed frame. The fixing assembly includes a fixing frame; the fixing frame is rotatably arranged on both sides of the fixed frame and surrounds the tree body.

[0011] Preferably, a mounting plate is provided on one side of the material guiding barrel.

[0012] Preferably, the mounting plate is made of rubber.

[0013] Preferably, the sampling assembly includes:

[0014] A driving device, which is arranged inside the material guiding barrel;

[0016] A spiral conveying blade, which is arranged on the connecting rod;

[0017] And a material conveying pipe, which passes through the fixed frame and extends into the material guiding barrel.

[0018] Preferably, the fixing assembly further includes:

[0019] A connecting column, which is arranged on the fixing frame and rotatably connected to the fixed frame;

[0020] An extension plate, which is arranged on the fixing frame;

[0021] And a fixing bolt, which is threadedly connected to two groups of extension plates.

[0022] Preferably, the fixing frame is a semi-circular frame.

[0023] Compared with the prior art, the utility model has the following beneficial technical effects:

[0024] By setting the fixing assembly, it can ensure that the sampling tool is firmly fixed on the surface of the tree trunk, avoid errors caused by movement or instability, improve the stability and accuracy during sampling, and ensure the reliability of data; and the operator can more easily install the sampling tool on the tree trunk, without the need to continuously hold it by hand or use other supporting tools, which simplifies the operation process and improves work efficiency.

Detailed implementation manners

[0029] Embodiment 1

[0030] As Figures 1 - 3 shown, a monitoring and sampling tool for pine wilt disease proposed by the present utility model includes a fixed frame 1, a material guiding barrel 3, a sampling assembly and a fixing assembly;

[0031] The material guiding barrel 3 passes through the fixed frame 1, and a circular groove fitted with the material guiding barrel 3 is provided in the middle of the fixed frame 1; the sampling assembly is arranged on the material guiding barrel 3 and is used for sampling the tree body in the working state; the fixing assembly is arranged on the fixed frame 1, and the fixing assembly includes a fixing bracket 2; the fixing bracket 2 is rotatably arranged on both sides of the fixed frame 1 and surrounds the tree body.

[0032] As Figures 1 - 2 shown, a mounting plate 5 is arranged on one side of the material guiding barrel 3, and the mounting plate 5 is made of rubber; the fixing assembly further includes a connecting column 4, an extension plate 6 and a fixing bolt 7; the connecting column 4 is arranged at one end of the fixing bracket 2 and is rotatably connected with the fixed frame 1; the extension plate 6 is arranged at the other end of the fixing bracket 2; the fixing bolt 7 is threadedly connected with two groups of extension plates 6, the fixing bracket 2 is a semi-circular bracket, and two groups of fixing brackets 2 can surround the tree body, and then the sampling device is fixed on the tree trunk through the fixing bolt 7 for sampling work. The fixing assembly can enable the operator to more easily install the sampling tool on the tree trunk, without the need to continuously hold it by hand or use other supporting tools, simplifies the operation process and improves the work efficiency.

[0033] Embodiment 2

[0034] A monitoring and sampling tool for pine wilt disease proposed by the present utility model further details the structure of the sampling assembly compared with Embodiment 1.
