Description

Technical Field

[0001] The utility model relates to the technical field of arthropod capture, in particular to a surface arthropod trap catcher. Background Art

[0002] As a standard method for sampling surface arthropods, the trap method has the advantages of low cost, easy operation, applicability to various habitats, and ability to provide a large amount of data. The traditional trap method uses a trap catcher for sampling. The trap catcher is generally a cylindrical container with one end open. When in use, the trap catcher is buried underground with the opening flush with the ground. A certain amount of preservation liquid is loaded into the catcher. When surface arthropods fall into the catcher, they are preserved in the preservation liquid.

[0003] In summary, although the trap method is widely used in various ecological surveys, there are still many deficiencies in the design of trap catchers:

[0004] 1. The trap catcher composed of a single container needs to dig out the entire catcher during each investigation, resulting in a large workload, significant damage to the surface soil layer, and a huge impact on the surface ecology.

[0005] 2. In order to better trap arthropods, the upper diameter of the trap catcher is set relatively large, and the preservation liquid inside volatilizes quickly. In case of rain, rainwater easily enters the trap catcher, diluting the preservation liquid, which may cause the captured arthropod samples to deteriorate, making the samples lose effectiveness or change their characteristics; or cause the chemical components of the preservation liquid to become ineffective, resulting in the escape of arthropods.

[0006] 3. Most of the existing trap catchers are integrally formed structures. When taking out the arthropod samples, it is necessary to turn over the trap catcher to pour out the samples, which may cause the spillage of the preservation liquid, not conducive to the reuse of the preservation liquid, and also has a certain impact on the ecological environment. Content of the Utility Model

[0007] Therefore, the utility model provides a surface arthropod trap catcher to solve the above problems in the prior art.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] According to the first aspect of the present utility model, a ground arthropod trap catcher includes a cylinder body that can be embedded in the ground. A trap solution is injected into the cylinder body. An open trap is inserted and installed at the upper opening of the cylinder body. The open trap has a frustum structure with upper and lower openings, and the open trap can trap and collect arthropods. An umbrella-shaped rain shield is arranged above the open trap. A support rod is fixedly installed on the bottom surface of the umbrella-shaped rain shield, and the lower end of the support rod is fixedly connected to the upper edge of the open trap. A jacket filter is installed at the lower part of the open trap. The jacket filter is detachably separated from the open trap. The jacket filter can filter out the trap solution and can be unfolded to let the arthropods fall out.

[0010] Further, the jacket filter includes filter clamping plates. There are two filter clamping plates, and the two filter clamping plates can be assembled into a cup-shaped structure. A hinge is installed on one side of the two filter clamping plates, and the two filter clamping plates are rotatably connected through the hinge.

[0011] Further, the jacket filter includes filter clamping plates. There are two filter clamping plates, and the two filter clamping plates can be assembled into a cup-shaped structure. A hinge is installed on one side of the two filter clamping plates, and the two filter clamping plates are rotatably connected through the hinge.

[0012] Further, the jacket filter includes a filter screen, and the filter screen is fixedly installed at the bottom of the filter clamping plate.

[0013] Further, an annular groove is provided at the upper part of the inner wall of the filter clamping plate, and an annular protrusion is provided at the lower end of the outer wall of the open trap. The annular protrusion can be embedded in the annular groove, and the filter clamping plate is clamped and installed at the lower part of the open trap through the annular groove.

[0014] Further, an annular protruding structure is provided on the outer wall of the upper edge of the open trap. When the open trap is inserted into the cylinder body, the protruding structure on the outer edge of the open trap can be stuck at the top edge of the cylinder body.

[0015] The present utility model has the following advantages:

[0016] 1. Adopting a split structure, the cylinder body is embedded in the ground. When investigating and capturing arthropods, by pulling out the open trap and then detaching the jacket filter at the lower part of the open trap, the effect of conveniently and quickly taking out the sample can be achieved, without digging out the entire catcher, and the impact on the ecological environment of the surface soil layer is small.

[0017] 2. By arranging an umbrella-shaped rain shield above the open trap, the effects of blocking rainwater and slowing down the evaporation of the trap solution can be achieved, preventing rainwater from entering the open trap and the cylinder body, maintaining the effectiveness of the chemical components in the trap solution, and improving the trapping efficiency of arthropods.

[0018] 3. When the open trap is withdrawn from the cylinder body, the trap solution is filtered through the jacket filter, and then the jacket filter is pressed to expand it, allowing the arthropods to fall out, so as to avoid the spillage of the trap solution, which is beneficial to the reuse of the trap solution and also makes the process of taking out the arthropod sample more convenient.

[0025] Embodiment 1

[0026] As Figures 1 to 4As shown in the figure, a ground arthropod trap catcher in the first aspect embodiment of the present utility model includes a cylinder 11 which can be embedded in the ground. A trap solution is injected into the cylinder 11. An open trap 12 is inserted and installed at the upper opening of the cylinder 11. The open trap 12 has a frustum structure with openings at both the top and bottom. The open trap 12 can trap and collect arthropods. An umbrella-shaped rain shield 13 is arranged above the open trap 12. A support rod 14 is fixedly installed on the bottom surface of the umbrella-shaped rain shield 13. The lower end of the support rod 14 is fixedly connected to the upper edge of the open trap 12. A jacket filter is installed at the lower part of the open trap 12. The jacket filter is detachably separated from the open trap 12. The jacket filter can filter out the trap solution and can be unfolded to let the arthropods fall out.

[0027] In the above embodiment, it should be noted that before installation, a straight cylindrical round hole needs to be dug on the ground surface. The trap solution in the cylinder 11 needs to be injected to half of the inside of the cylinder 11 and completely cover the jacket filter at the lower part of the open trap 12. The trap solution includes a solution to prevent specimens from climbing out and preserve soil animal specimens, which is colorless and odorless. And the trap solution can prevent arthropods from escaping and rotting. The coverage area of the umbrella-shaped rain shield 13 is larger than the upper edge area of the cylinder 11.

[0028] The technical effects achieved by the above embodiment are as follows: The cylinder 11 is embedded in the ground, and the trap solution is injected into the cylinder 11. Then the open trap 12 and the jacket filter are inserted into the cylinder 11. Arthropods are attracted by the trap solution, fall into the open trap 12 and drop to the bottom of the jacket filter. When investigating the captured arthropods, by pulling out the open trap 12 and then pressing to detach the jacket filter at the lower part of the open trap 12, the effect of conveniently and quickly taking out the sample can be achieved without digging out the whole catcher, and the impact on the surface soil layer ecology is relatively small. When the open trap 12 is pulled out of the cylinder, the trap solution is filtered out by the jacket filter, and then the jacket filter is pressed to unfold it to let the arthropods fall out, so as to achieve the effect of avoiding the spillage of the trap solution, which is beneficial to the reuse of the trap solution and also makes the process of taking out the arthropod sample more convenient. At the same time, the umbrella-shaped rain shield 13 arranged above the open trap 12 can achieve the effects of blocking rainwater and slowing down the volatilization of the trap solution, preventing rainwater from entering the open trap 12 and the cylinder 11, maintaining the effectiveness of the chemical components in the trap solution, and improving the trapping efficiency of arthropods.
