Description

Technical Field

[0001] This utility model relates to the field of bullet tail eye collection technology, and in particular to a portable bullet tail eye live field collector. Background Technology

[0002] Springtails are a group of tiny, six-legged invertebrates, commonly known as springtails or snapdragons, widely distributed in moist environments such as soil, humus, and leaf litter. They typically range in size from 0.2 to 5 millimeters, with some tropical species reaching 10 millimeters. They feed on humus, fungi, or microorganisms, playing an important role as decomposers in the ecosystem.

[0003] Because of their tiny size, traditional collection methods (such as tweezers or sweeping nets) are inefficient. Therefore, negative pressure adsorption is usually used. The collector uses a miniature negative pressure pump to generate suction, which draws the target insect along with the surrounding substrate. Then, the built-in filter separates the insect. This method can collect live samples quickly and gently, while reducing interference with the surrounding environment. It is especially suitable for working in complex substrates (such as leaf litter or soil).

[0004] The order Collembola includes several families, such as the families Phyllotyridae, Echinocytiidae, and Echinocytiidae. Different groups exhibit significant differences in body size, thus requiring the replacement of filters with appropriate mesh sizes before collection to ensure efficiency. However, most current collectors use screws to fix the filters, necessitating the removal of multiple bolts with tools when replacing them. This is not only cumbersome but also prone to losing parts or delaying collection in the field, causing inconvenience for Collembola collection. Therefore, a portable Collembola field live specimen collector is proposed to address these issues. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a portable live insect collector for the order Bruxelles, comprising a collection tube 1, with a mask 2 fixedly installed at the bottom of the collection tube 1 to expand the adsorption range of the collection tube 1. The interior of the collection tube 1 is connected to the interior of the mask 2. A miniature negative pressure pump 3 is fixedly installed at the top of the collection tube 1, with its input end connected to the interior of the collection tube 1. When the miniature negative pressure pump 3 is activated, a negative pressure is generated at the front end of the collection tube 1 by pumping air, drawing insects into the interior of the collection tube 1 through the mask 2. A handle 4 is fixedly installed on the outer wall of the collection tube 1, and a disc 5 is fixedly installed on the outer wall of the collection tube 1. The interior of the disc 5 is connected to the interior of the collection tube 1. An opening 51 is provided at the bottom of the disc 5 for discharging impurities attached to the filter frame 64 from the disc 5. An adjustment mechanism and a cleaning mechanism 8 are provided inside the disc 5.

[0034] Reference Figure 2 , Figure 3 and Figure 5 The adjustment mechanism includes a filter assembly 6, which includes a rotating shaft 61 that passes through and is rotatably connected to the inner wall of the disc 5. A knob 62 is fixedly installed on the top of the rotating shaft 61. Rotating the rotating shaft 61 via the knob 62 causes the connecting rod 63 to rotate synchronously. The connecting rod 63 is fixedly installed on the outer wall of the rotating shaft 61, and a filter frame 64 is fixedly installed at the end of the connecting rod 63 away from the rotating shaft 61. Rotating the connecting rod 63 causes the filter frame 64 to rotate around the rotating shaft 61 in a circular motion. The outer wall is attached to the inner wall of the collection tube 1. There are four sets of filter frames 64, and each of the four sets of filter frames 64 has a filter screen inside. The mesh size of the four filter screens is different. By setting four sets of filter frames 64 with different mesh sizes, they can be flexibly replaced when collecting Collembola in the field. Sealing gaskets 65 are fixedly installed on the upper and lower sides of the filter frame 64. The sealing gaskets 65 are attached to the inner wall of the collection tube 1. When the filter frame 64 is rotated to be concentric with the collection tube 1, the connection between the filter frame 64 and the collection tube 1 can be sealed by the sealing gaskets 65.

[0035] Reference Figure 3 and Figure 5The adjustment mechanism also includes a limiting component 7, which includes a limiting rod 71. The limiting rod 71 passes through and is slidably connected to the inner wall of the handle 4. The limiting rod 71 is a rectangular rod, and a crossbar 72 is fixedly installed on the outer wall of the limiting rod 71. Holding the handle 4 and pushing the crossbar 72 upward with a finger causes the crossbar 72 to move the limiting rod 71 upward along the inner wall of the handle 4, thus moving the limiting rod 71 out of the limiting hole 73. The top of the knob 62 has a limiting hole 73 for the limiting rod 71 to be inserted. Hole 73 is a rectangular groove. When the limiting rod 71 is inserted downward into the limiting hole 73, the knob 62 can be limited by the limiting rod 71 and the limiting hole 73. One end of the limiting rod 71 is attached to the inner wall of the limiting hole 73, and the other end of the limiting rod 71 is fixedly installed with a spring 74. The end of the spring 74 away from the limiting rod 71 is fixedly installed on the inner wall of the handle 4. When the crossbar 72 is released, the spring 74 will push the limiting rod 71 downward, so that the limiting rod 71 slides downward on the inner wall of the handle 4.

[0036] Reference Figure 2 , Figure 4 and Figure 5 The cleaning mechanism 8 includes a rotating rod 81. One end of the rotating rod 81 is rotatably connected to the inner wall of the connecting rod 63, and the other end of the rotating rod 81 is fixedly mounted with a guide wheel 82. While the guide wheel 82 rolls against the outer wall of the arc-shaped guide rail 85, it drives the rotating rod 81 to rotate on the inner wall of the connecting rod 63. A rubber rod 83 is fixedly mounted on the outer wall of the rotating rod 81, and a steel ball 84 is fixedly mounted on the end of the rubber rod 83 away from the rotating rod 81. When the rotating rod 81 rotates, it works with the rubber rod 83 to drive the steel ball 84 to make a circular motion around the rotating rod 81. The outer wall of the steel ball 84 is in contact with the filter frame 6. The steel ball 84 repeatedly strikes the outer wall of the filter frame 64 while rotating around the rotating rod 81, which can shake off the impurities attached to the surface of the filter frame 64. The impurities on the surface of the filter frame 64 can fall down through the opening 51 and be discharged from the disc 5. The inner wall of the disc 5 is fixedly installed with an arc-shaped guide rail 85. The arc-shaped guide rail 85 and the rotating shaft 61 are concentric. The guide wheel 82 is attached to the outer wall of the arc-shaped guide rail 85. When the rotating rod 81 moves, it drives the guide wheel 82 to contact the arc-shaped guide rail 85. The guide wheel 82 will roll against the outer wall of the arc-shaped guide rail 85.

[0037] Working principle: When in use, hold the handle 4 and push the crossbar 72 upward with your fingers. This causes the crossbar 72 to drive the limiting rod 71 to slide upward on the inner wall of the handle 4. As the limiting rod 71 slides upward, it compresses the spring 74 and gradually moves out of the limiting hole 73. When the limiting rod 71 has completely moved out of the limiting hole 73, the limitation on the knob 62 can be released. At this time, the rotating shaft 61 can be rotated by the knob 62. When the crossbar 72 is released, the spring 74 will push the limiting rod 71 downward, causing the limiting rod 71 to slide downward on the inner wall of the handle 4. This allows the limiting rod 71 to be inserted into the limiting hole 73. At this time, the limiting rod 71 and the limiting hole 73 can be used to limit the knob 62, thereby limiting the rotating shaft 61 to the inner wall of the disc 5.

[0038] Rotating the rotating shaft 61 by knob 62 will cause the connecting rod 63 to rotate synchronously. At this time, the connecting rod 63 can drive the filter frame 64 to make a circular motion around the rotating shaft 61, thereby driving the filter frame 64 to rotate inside the disc 5. Then, the appropriate filter frame 64 can be rotated into the collection tube 1 for filtration as needed. Furthermore, by setting four sets of filter frames 64 with different mesh sizes, they can be flexibly changed when collecting Collembola in the field.

[0039] While the rotating shaft 61 drives the connecting rod 63 to rotate, the connecting rod 63 drives the rotating rod 81 to move synchronously. When the rotating rod 81 moves, it drives the guide wheel 82 to contact the arc-shaped guide rail 85. The guide wheel 82 will roll against the outer wall of the arc-shaped guide rail 85. At the same time, the guide wheel 82 will drive the rotating rod 81 to rotate on the inner wall of the connecting rod 63. While the rotating rod 81 rotates, it will drive multiple sets of rubber rods 83 to rotate synchronously. At this time, the rubber rods 83 will drive the steel ball 84 to make a circular motion around the rotating rod 81. At the same time, the steel ball 84 will repeatedly hit the outer wall of the filter frame 64. By hitting the outer wall of the filter frame 64, the impurities attached to its surface can be shaken off downwards. The impurities on the surface of the filter frame 64 can fall down through the opening 51 and be discharged from the disc 5, thereby enabling the filter frame 64 to self-clean so that the filter frame 64 can better filter colliders.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
