Description

Technical Field

[0001] The invention relates to the technical field of insect separation, and in particular to a surface insect separation device. Background Art

[0002] Insects are an important part of natural ecosystems. In the operation of ecosystems, they play a role in maintaining the flow of matter, energy and information in the ecosystem. Moreover, in certain specific ecosystems, insects are often regarded as key elements in maintaining the health of the ecosystem. At the same time, conducting relevant research on the insect community ecology of a region is an important part of understanding the structure and function of the ecosystem in that region, and collecting insects is an indispensable step in this process.

[0003] The most commonly used method for collecting insects is the sweeping net method, which mainly uses insect nets to collect insects. That is, when catching insects, the operator holds the net rod in his hand, with the net mouth facing the plant leaf layer, and sweeps the net to collect insects. However, during the sweeping net operation, debris such as plant branches, leaves and seeds are swept into the insect net along with the insects. Therefore, the current technical problem is how to successfully and efficiently separate the insects.

[0004] In order to solve the above technical problems, the commonly used separation methods are manual sorting and phototaxis insect sorting devices. In order to prevent insects from escaping, manual sorting requires the use of poison bottles, fumigation and other methods to kill insects, but these methods have safety hazards. At the same time, some insects are still difficult to distinguish from plant branches, leaves and seeds after death, or have problems such as deformation and discoloration, which is not conducive to sorting and later identification. In addition, these methods are often only suitable for indoor operations, with obvious space limitations, and cannot complete the processing of large quantities of samples in a short time.

[0005] Phototaxis insect traps mainly use the insects' phototaxis to separate them. However, experiments have shown that insects will instinctively escape after being caught in a net, and their response to the attracting light source is weak, resulting in low separation efficiency. In addition, the phototaxis of insects has a certain wavelength range. If the wavelength of the light source is not within the range that the insects tend to, the insects will not tend to the light source. In addition, phototaxis insect traps also involve issues such as backup power supply, which further limits their scope of use.

[0006] In addition to the above-mentioned separation of insect samples, some studies also require marking and recapture of some insects with stronger mobility, that is, it is necessary to collect complete samples of living insects. Therefore, in the process of using the sweeping net method to study surface insects, an efficient and safe surface insect separation device is urgently needed. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to solve the safety problems, space limitations and low separation efficiency in traditional separation methods, and to provide a surface insect separation device that not only avoids the harm of toxic and harmful substances to the human body, but also avoids the destruction of insect samples, and has an unlimited scope of use.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A surface insect separation device comprises a collecting section and a placing section, wherein a channel for accommodating surface insects passing therethrough is arranged between the placing section and the collecting section, the channel comprises a transition section which is arranged transversely and has a rough surface inside, and a smooth section which is arranged vertically and has a smooth surface inside, the inlet of the smooth section is connected with the outlet of the transition section, and further comprises a bracket for locking and adjusting the height of the transition section; wherein the placing section is provided with a storage container for accommodating a plurality of surface insects and debris, the bottom of the storage container is provided with a cover for covering the surface insects and debris, and the top of the storage container is provided with an opening connected to the inlet of the transition section; the collecting section is provided with a collecting container for accommodating a plurality of surface insects, the top of the collecting container is a narrow opening, and the narrow opening is connected with the outlet of the smooth section.

[0010] Since the insect net used in the sweeping net method generally has a large mesh opening, if the insect net is directly connected to the surface insect separation device of the present invention, the surface insects are more likely to escape. Therefore, the surface insects containing debris in the insect net need to be transferred to the storage container of the placement section.

[0011] The actual operation is: directly set up a bracket at the working place, gather the surface insects and debris in one place through the sweeping net method, and cover the surface insects and debris through the cover of the storage container, and the surface insects in the debris such as plant branches, leaves and seeds will climb up along the debris such as plant branches, leaves and seeds, and at the same time, when affected by the outside world, the surface insects will crawl along the inner wall of the storage container into the channel due to the instinct of stress escape, and crawl to the smooth section through the transition section with a rough surface. Since the inner wall of the smooth section is a smooth surface, the three pairs of feet of the surface insects have no fulcrum. At the same time, the smooth section is vertically arranged, and the surface insects will quickly slide into the collection container below, thereby realizing the separation of the surface insects and debris.

[0012] Furthermore, the container is a sample bag of a mesh body, a mesh cloth cover is arranged around the opening, and a thin rope passing through the mesh body and the mesh cloth cover is arranged on the mesh cloth cover.

[0013] A mesh cloth cover is set at the opening of the sample bag and is fixed to the sample bag using a thin rope. This design is to prevent the mesh wire at the opening of the sample bag from being derailed.

[0014] Furthermore, a connecting ring is provided at the junction of the sample bag and the channel, and an annular slot is provided at the upper end of the connecting ring, and the slot is used to limit the sample bag that passes through the interior of the connecting ring and extends outward to the slot.

[0015] The opening of the sample bag passes through the inside of the connecting ring and is folded outwards, and is fixed to the card slot outside the connecting ring by means of a thin rope such as a rubber band, so as to connect the opening of the sample bag with the connecting ring.

[0016] Furthermore, the channel is a conduit for a plurality of surface insects to crawl through, the transition section and the smooth section are both arranged in the conduit, and the conduit also includes a connecting section, and the inlet of the connecting section is fixedly connected to the connecting ring.

[0017] The conduit is provided to facilitate the crawling of surface insects. At the same time, the connecting section and the connecting ring realize the connection between the sample bag and the conduit, so that the surface insects in the sample bag crawl from the sample bag into the conduit. The rough surface is provided to facilitate the stable crawling of surface insects. Moreover, they can crawl on the circumferential surface of the transition section, thereby expanding the crawling area and allowing more surface insects to crawl to the smooth section through the transition section.

[0018] Furthermore, it also includes screws, the connecting ring is provided with a plurality of first positioning holes near the slot, the connecting section is provided with a plurality of second positioning holes arranged opposite to the first positioning holes, and the first positioning holes are connected to the second positioning holes by screws.

[0019] The connection ring and the channel are fixed by the first positioning hole on the connection ring and the second positioning hole on the connection section. The screw connection is used for easy disassembly and replacement of the connection ring.

[0020] Furthermore, the rough surface is a gauze attached to the inner wall of the transition section. The rough surface is made of gauze because the gauze has the characteristics of good toughness, corrosion resistance, easy cleaning and not easy to deform.

[0021] Furthermore, the collection container comprises a conical funnel and a specimen preservation bottle, wherein the funnel is arranged between the smooth section and the specimen preservation bottle, the narrow mouth of the specimen preservation bottle is connected to the narrow mouth of the funnel, and the wide mouth of the funnel wraps the smooth section.

[0022] When the surface insects slide into the smooth section, due to the smooth surface and vertical setting of the smooth section, the surface insects cannot land on the smooth section, so the surface insects fall into the specimen preservation bottle through the funnel. The wide mouth of the funnel wraps the smooth section, and the narrow mouth takes it into the specimen preservation bottle, so as to prevent large surface insects from blocking the funnel.

[0023] Furthermore, the support includes a sleeve-type main support rod, which includes an outer tube and at least one retractable inner tube nested in the outer tube. The transition section of the catheter is fixed to the outer tube. The outer tube is provided with a first iron ring located below the transition section and used to place a funnel. The inner tube is provided with a second iron ring for placing a specimen preservation bottle, and the second iron ring is arranged parallel to the first iron ring.

[0024] The first iron ring and the second iron ring are provided to fix the funnel and the specimen preservation bottle. At the same time, the first iron ring and the second iron ring are respectively located on the outer tube and the inner tube to fix the positions of the first iron ring and the second iron ring. The first iron ring and the second iron ring are parallel to each other to realize the parallelism between the funnel and the specimen preservation bottle.

[0025] Furthermore, the inner tube is provided with three diagonal support rods located below the second iron ring, the diagonal support rods are provided with a plurality of fixing holes, the inner tube is provided with three spaced-apart positioning screws perpendicular to the main support rods, the three positioning screws each pass through a fixing hole so that the three diagonal support rods form a triangular cone.

[0026] During operation, select a suitable fixing hole and pass the positioning screw on the main support rod, adjust the angle of the diagonal support rod, and tighten it with a butterfly nut so that the three diagonal support rods form a triangle with the main support rod. According to the triangle stability principle, this design makes the main support rod stable.

[0027] Furthermore, a ground plug located at the bottom end of the inner tube is provided at the bottom of the main support rod, and the ground plug is used to assist in supporting the main support rod.

[0028] Compared with the prior art, the present invention has the advantages of safety, high efficiency, low cost, and portability in the field.

[0029] 1. The present invention utilizes the stress-escape instinct of surface insects to separate surface insects. The whole process does not require the use of poison bottles, fumigation and other methods to kill the insects and then separate them, making the whole process safer, avoiding the harm of toxic and harmful substances to the human body, and also avoiding the destruction of insect samples.

[0030] 2. The present invention can separate ground insects such as Coleoptera, Diptera, Hymenoptera, and Hemiptera that crawl upward along a single line in the sample bag due to stress escape, without the need for manual screening, with high separation efficiency and not restricted by field conditions, thus providing convenience for subsequent scientific research.

[0038] The rough surface is a gauze attached to the inner wall of the transition section 4. The rough surface adopts the gauze because the gauze has the characteristics of good toughness, corrosion resistance, easy cleaning and not easy to deform.

[0039] The actual operation is: directly set up a bracket at the working place, gather the surface insects and debris in one place through the sweeping net method, and cover the surface insects and debris through the cover of the storage container, so that the surface insects in the debris such as plant branches, leaves and seeds will climb up along the debris such as plant branches, leaves and seeds, and at the same time, when affected by the outside world, the surface insects will crawl along the inner wall of the storage container into the channel due to the instinct of stress escape, and crawl to the smooth section 5 through the transition section 4 with a rough surface. Since the inner wall of the smooth section 5 is a smooth surface, the three pairs of feet of the surface insects have no fulcrum. At the same time, the smooth section 5 is vertically arranged, and the surface insects will quickly slide into the collection container below, thereby realizing the separation of the surface insects and debris.

[0040] The container is a sample bag 1 of a mesh body, the lower part of the sample bag 1 is approximately trapezoidal, the bottom width is 30 cm, the top width is about 22 cm (the diameter when stretched into a circle is about 7 cm), and the overall height of the sample bag 1 is 40 cm. The sample bag 1 is sewn with nylon mesh.

[0041] A mesh cloth sleeve is arranged around the opening of the sample bag 1, and a thin rope is arranged on the mesh cloth sleeve and is passed through the mesh body and the mesh cloth sleeve. The mesh cloth sleeve is arranged at the opening of the sample bag 1 and is fixed to the sample bag 1 with a thin rope. This design is to prevent the mesh wire at the opening of the sample bag 1 of the mesh body from being derailed.

[0042] A connecting ring 2 is provided at the junction of the sample bag 1 and the channel. The connecting ring 2 is made of a transparent hard plastic round tube, 5 cm in height, 6.3 cm in outer diameter, and about 0.4 cm in thickness. An annular card slot 21 is provided at the upper end of the connecting ring 2. The card slot 21 has a depth of 0.2 cm. The card slot 21 is used to limit the sample bag 1 that passes through the interior of the connecting ring 2 and extends outward to the card slot 21. The opening of the sample bag 1 passes through the interior of the connecting ring 2 and is folded outward, and is fixed to the card slot 21 outside the connecting ring 2 by means of a thin rope such as a rubber band, so that the opening of the sample bag 1 is connected to the connecting ring 2.

[0043] The channel is a conduit for multiple ground insects to crawl through. The total height of the conduit is 17.0 cm, the length of the horizontal pipe part is 5.0 cm, and the material is a transparent PVC U-shaped elbow pipe with an elbow angle of 90°, an inner diameter of 6.4 cm, and a thickness of about 0.6 cm. The transition section 4 and the smooth section 5 are both arranged in the conduit. The conduit also includes a connecting section 3, and the inlet of the connecting section 3 is fixedly connected to the connecting ring 2.

[0044] The conduit is provided to facilitate the crawling of surface insects. At the same time, the connecting section 3 and the connecting ring 2 realize the connection between the sample bag 1 and the conduit, so that the surface insects in the sample bag 1 crawl from the sample bag 1 into the conduit. The rough surface is provided to facilitate the stable crawling of surface insects, and they can crawl on the circumferential surface of the transition section 4, thereby expanding the crawling area, so that more surface insects can crawl to the smooth section 5 through the transition section 4.

[0045] Two first positioning holes 22 are symmetrically arranged near the slot 21 on the connecting ring 2, and two second positioning holes 31 are arranged opposite to the first positioning holes 22 on the end of the connecting section 3, and the first positioning holes 22 and the second positioning holes 31 are connected by screws. The fixing of the connecting ring 2 and the channel is achieved by the first positioning holes 22 on the connecting ring 2 and the second positioning holes 31 of the connecting section 3, and the screw connection is used for easy disassembly and replacement of the connecting ring 2.

[0046] The collection device includes a conical funnel 6 and a specimen preservation bottle 7. The diameter of the funnel 6 is 10 cm, the diameter of the hole of the funnel 6 is 3.0 cm, the wide mouth of the funnel 6 wraps the vertically arranged smooth section 5, the funnel 6 is arranged between the smooth section 5 and the specimen preservation bottle 7, and the narrow mouth of the specimen preservation bottle 7 is connected to the narrow mouth of the funnel 6. The specimen preservation bottle 7 is made of PET transparent plastic. Preferably, the capacity of the specimen preservation bottle 7 is determined according to the number of captured insects, and can be selected as 100 ml or 200 ml; the diameter of the specimen preservation bottle 7 is 4.0-5.0 cm, and the bottle is filled with 1 / 3 of an ethanol solution with a concentration of 75%.

[0047] When the ground insects slide into the smooth section 5, due to the smooth surface of the smooth section 5 and the vertical arrangement, the ground insects cannot land on the smooth section 5, so the ground insects fall into the specimen preservation bottle 7 through the funnel 6. The wide mouth of the funnel 6 wraps the smooth section 5, and the narrow mouth takes it into the specimen preservation bottle 7, so that large surface insects cannot block the funnel 6.

[0048] The main support rod 12 is composed of three stainless steel pipes with a diameter of 2 cm and a length of 40 cm. The steel pipes are connected by internal and external threads, and the thread length is 4 cm. The main support rod 12 is divided into an outer pipe 123, a first inner pipe 122 is nested in the outer pipe, and a second inner pipe 121 is nested in the first inner pipe. The transition section 4 of the catheter is fixed to the outer pipe 123. Figure 3 The outer tube 123 is provided with a first iron ring located below the transition section 4 and used to place the funnel 6, and the first inner tube 122 is provided with a second iron ring 14 for placing the specimen preservation bottle 7, and the second iron ring 14 is arranged parallel to the first iron ring.

[0050] The first inner tube 122 is provided with three diagonal struts 11 located below the second iron ring 14. The diagonal struts 11 are made of thick iron sheets. The diagonal struts 11 are 70.0 cm long, 3.0 cm wide, and 0.3 cm thick. The diagonal struts 11 are provided with a plurality of fixing holes 111. The first inner tube 122 is provided with three spaced apart positioning screws 9 that are perpendicular to the main struts 12. The angles between the three positioning screws 9 are all 120°. The three positioning screws 9 each pass through a fixing hole 111 so that the three diagonal struts 11 form a triangular cone.

[0051] During operation, select a suitable fixing hole 111 to pass the positioning screw 9 on the diagonal support rod 11, adjust the angle of the diagonal support rod 11, and tighten it with a butterfly nut so that the three diagonal support rods 11 form a triangle with the main support rod 12. According to the triangle stability principle, this design makes the main support rod 12 stable. The bottom of the main support rod 12 is provided with a ground plug 13 located at the bottom end of the second inner tube 121.
