Description

Technical Field

[0001] This invention relates to the field of biodiversity survey technology, and more specifically to a collection device for insect biodiversity surveys. Background Technology

[0002] Insects are the most abundant animals in the world, with more than one million species discovered, more than all other animal species combined. Therefore, insects are an important part of global biodiversity and an important focus of biodiversity conservation research in recent years.

[0003] In insect biodiversity surveys, sample collection is required. Currently, the common sample collection method is to trap insects in sealed containers, such as using food scraps or releasing aggregation pheromones to trap ants, or using phototaxis or xanthophoresis to trap aphids. Existing trap collection devices generally adopt a box structure with multiple entrances, and place the trapping source directly inside the box, allowing insects to crawl into the box through the entrances and achieve insect collection. This collection device has the following drawbacks: (1) Placing the trapping source directly in the box space makes it difficult to separate the insects from the trapping source later, thus making it difficult to collect and transfer the insects; (2) The entrance to the box is always open. If there is no manual collection for a long time, some insects that have entered the box will crawl out again, resulting in poor collection efficiency; (3) In order to reduce the foreign body sensation of insects to the box, the box size is generally set to be large, which further leads to the inconvenience of insect collection and transfer. Summary of the Invention

[0004] The purpose of this invention is to provide a collection device for insect biodiversity surveys, which solves the shortcomings of existing collection devices, such as inconvenience in insect collection and transfer and poor collection efficiency.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A collection device based on insect biodiversity survey includes a trapping box with several inlets on its side wall. The trapping box contains a collection plate and a drive unit for raising and lowering the collection plate. The collection plate divides the trapping box into upper and lower cavities, and several trapping sources are provided in the lower cavity. Each trapping source on the collection plate has a through hole at a position corresponding to the through hole, and the through hole is covered with an elastic permeable membrane.

[0007] When the driving component drives the collection plate to the bottom, the trapping source enters the upper cavity through the through hole and diffuses the trapping information to the surroundings through the elastic membrane, inducing insects to crawl into the surface of the upper cavity of the collection plate from the inlet. When the driving component drives the collection plate to rise, the collection plate separates from the trapping source and the inlet is no longer connected to the upper cavity.

[0008] A further improvement is that the trapping source is one of food residue, pheromones, or a light source, and the elastic permeable membrane is one of a breathable mesh or a light-transmitting membrane.

[0009] A further improvement is that two horizontal first slide rails are provided at opposite edges above the collection plate. Two gathering plates are provided in the upper cavity. The gathering plates are parallel to each other and vertically arranged. The bottom edge of the gathering plate contacts the collection plate, and the side edge contacts the wall of the trap box, so that a collection area for accommodating insects is formed between the gathering plates. Both sides of the gathering plate are slidably connected to the first slide rails through sliding sleeves. A compression spring is provided between the two sliding sleeves on the same first slide rail. Two sets of guide bodies are symmetrically arranged in the upper cavity. The opposite side of the two sets of guide bodies is inclined, so that the distance between the opposite sides of the two sets of guide bodies gradually decreases from bottom to top. The top edge of the gathering plate contacts the inclined surface of the corresponding guide body. When the driving component drives the collection plate to rise, the two gathering plates move towards each other along the first slide rails under the action of the inclined surface of the guide body to reduce the width of the collection area and allow insects to gather.

[0010] A further improvement is that the bottom edge of the gathering plate is movably provided with a cylindrical brush that is in contact with the collection plate, and the top edge of the gathering plate is provided with a drive gear. The drive gear and the cylindrical brush are connected by a transmission belt. The inclined surface of the guide body has a toothed structure, and the inclined surface is meshed with the drive gear. When the two gathering plates move towards each other along the first slide rail under the action of the inclined surface of the guide body, the drive gear rolls along the inclined surface and drives the cylindrical brush to sweep along the collection plate through the transmission belt, and the sweeping direction is the same as the moving direction of the gathering plate.

[0011] A further improvement is that the trapping box has an open-top air intake box, a horizontal piston plate inside the air intake box, and a storage box on the side of the trapping box. The storage box is connected to the space below the piston plate in the air intake box via a connecting pipe. The top of the guide body is sealed and slidably inserted into the air intake box and connected to the piston plate via a connecting rod. The bottom of the guide body has a horizontal surface. A second slide rail is horizontal and perpendicular to the first slide rail on the guide body. A rigid air intake pipe slides on the second slide rail. One end of the air intake pipe extends to the collection area and is equipped with a suction head. The other end of the air intake pipe is connected to the storage box via a flexible hose. A third slide rail is inclined on the inner wall of the trapping box and its vertical projection is parallel to the second slide rail. The air intake pipe is slidably connected to the third slide rail via a sliding claw.

[0012] When the drive unit drives the collection plate to rise until the first slide rail contacts the bottom horizontal surface of the guide body, the suction head is in contact with the surface of the collection plate. If the drive unit continues to drive the collection plate to rise, it will push the guide body and the suction pipe to rise synchronously through the first slide rail, so that the two gathering plates stop moving towards each other. Under the action of the third slide rail, the suction pipe moves along the second slide rail, thereby driving the suction head to move along the collection area. At the same time, the guide body drives the piston plate to rise through the connecting rod, so that the space under the piston plate generates negative pressure and forms a high-speed airflow from the suction head, suction pipe, hose, storage box to the suction box, so that the insects in the collection area are sucked into the storage box.

[0013] A further improvement is that each set of guide bodies consists of two right-angled trapezoidal blocks, and the second slide rail is mounted between the two right-angled trapezoidal blocks.

[0014] A further improvement is that the connection between the storage box and the hose is equipped with a one-way valve that allows air to enter the storage box only through the hose, the connection between the storage box and the connecting pipe is equipped with an insect filter, and the lower space of the air intake box is equipped with a one-way valve that allows air to be exhausted only outward.

[0015] The beneficial effects of this invention are as follows:

[0016] (1) After trapping insects, the collection device can automatically separate the insects from the trapping source at one time, which facilitates the collection and transfer of insects and is conducive to the reuse of the trapping source.

[0017] (2) The collection device uses only the action of one drive component to simultaneously realize the shrinkage of the collection area, the movement and suction of insects, and the transfer and storage, which further improves the convenience of collection and transfer for large-sized trap boxes. When the collection area shrinks, it can avoid crushing insects. The periodic action of the drive component can prevent insects from escaping and improve collection efficiency.

Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Combination Figures 1-4 As shown, a collection device based on insect biodiversity surveys is mainly used for the survey and research of reptile diversity. It includes a trap box 1 with several inlets 2 on the side wall of the trap box 1. The inlets 2 can be arranged on opposite sides of the trap box 1. The trap box 1 contains a collection plate 3 and a drive unit 4 for driving the collection plate 3 to rise and fall. The drive unit 4 can be an existing device such as an electric telescopic rod or a push rod motor. When in use, the collection plate 3 is flush with the ground outside the trap box 1 and the lower edge of the inlets 2, which makes it easy for insects to crawl into the surface of the collection plate 3 along the inlets 2. The collection plate 3 divides the trap box 1 into upper and lower cavities, and several trapping sources 5 are provided in the lower cavity. The collection plate 3 has through holes at positions corresponding to each trapping source 5, and the through holes are covered with an elastic permeable membrane 6. The elastic permeable membrane 6 can be made of latex or other materials, and it can be stretched to one side and automatically contracted to a flat shape.

[0027] When the driver 4 drives the acquisition board 3 at the bottom (i.e.) Figure 1As shown in the diagram, the trapping source 5 enters the upper cavity through the through hole and diffuses the trapping information to the surroundings through the elastic permeable membrane 6, inducing insects to crawl into the upper cavity of the collection plate 3 from the inlet 2. When the driving component 4 drives the collection plate 3 to rise, the collection plate 3 separates from the trapping source 5 and the inlet 2 is no longer connected to the upper cavity. After separation, the insects remain on the collection plate 3 and are detached from the trapping source 5, which facilitates the collection of insects. The trapping source 5 will not be damaged during the collection process, making it easy to reuse the trapping source 5. The insects will also be unable to crawl out from the inlet 2. In addition, in order to keep the insects on the collection plate 3 and further facilitate the later collection, a blocking line (such as an electric heating wire) can be set at the bottom of the four sides of the trapping box 1 to prevent the insects from crawling onto the side walls.

[0028] Preferably, in this invention, the trapping source 5 is one of food residue, pheromones, or a light source. Correspondingly, the elastic permeable membrane 6 is one of a breathable mesh or a light-transmitting membrane. Insects cannot pass through the elastic permeable membrane 6, but the trapping information of the trapping source 5 can pass through the elastic permeable membrane 6.

[0029] Preferably, for a large-sized trapping box 1, insects are dispersed on a collection plate 3. To further facilitate insect collection, two horizontal first slide rails 7 are provided at opposite edges above the collection plate 3. Two gathering plates 8 are provided in the upper cavity (blocking lines can also be provided at the bottom of the side walls of the gathering plates 8). The gathering plates 8 are parallel to each other and vertically arranged. The bottom edge of the gathering plates 8 contacts the collection plate 3, and the side edge contacts the box wall of the trapping box 1, so that a collection area for accommodating insects is formed between the gathering plates 8. Both sides of the gathering plates 8 are connected to the first slide rails 7 via sliding sleeves 9. The slide rail 7 is slidably connected. A compression spring 10 is provided between two sliding sleeves 9 on the same first slide rail 7. Two sets of guide bodies 11 are symmetrically arranged in the upper cavity. The opposite sides of the two sets of guide bodies 11 are inclined surfaces 11a, causing the distance between the opposite sides of the two sets of guide bodies 11 to gradually decrease from bottom to top. The top edge of the gathering plate 8 contacts the inclined surface 11a of the corresponding guide body 11. When the driving component 4 drives the collection plate 3 to rise, the two gathering plates 8 move towards each other along the first slide rail 7 under the action of the inclined surface 11a of the guide body 11, thereby reducing the width of the collection area. (Refer to...) Figure 5 This allows insects to gather, making them easier to collect. When the drive unit 4 lowers the collection plate 3, the two gathering plates 8 move apart under the pressure of the compression spring 10 until they return to their original positions. Figure 1 The initial position is shown in the figure.

[0030] Preferably, in this invention, the bottom edge of the gathering plate 8 is movably provided with a cylindrical brush 12 that is in contact with the collection plate 3, and the top edge of the gathering plate 8 is provided with a drive gear 13. The drive gear 13 and the cylindrical brush 12 are connected by a transmission belt 14. The inclined surface 11a of the guide body 11 has a toothed structure, and the inclined surface 11a is meshed with the drive gear 13. When the two gathering plates 8 move towards each other along the first slide rail 7 under the action of the inclined surface 11a of the guide body 11, the drive gear 13 rolls along the inclined surface 11a and drives the cylindrical brush 12 to sweep along the collection plate 3 through the transmission belt 14, and the sweeping direction is the same as the moving direction of the gathering plate 8. For example, Figure 1 When the left-side gathering plate 8 moves to the right, the bottom brush 12 rotates counterclockwise. As the gathering plate 8 moves, the brush 12 sweeps the insects along the way toward the center, preventing insects from entering the gap between the gathering plate 8 and the collection plate 3 and being crushed. Crushed insects are not easy to collect and identify.

[0031] Preferably, in this invention, the trapping box 1 is provided with an air intake box 15 with an open top, and a horizontal piston plate 16 is provided inside the air intake box 15. A storage box 17 is provided on the side of the trapping box 1. The storage box 17 is connected to the space below the piston plate 16 in the air intake box 15 through a connecting pipe 18. The top of the guide body 11 is sealed and slidably inserted into the air intake box 15 through a connecting rod 19 and connected to the piston plate 16. The bottom of the guide body 11 has a horizontal surface 11b. A horizontal surface 11b is provided on the guide body 11 and is connected to the piston plate 16. A second slide rail 20 is perpendicular to a slide rail 7. A rigid suction tube 21 is slidably mounted on the second slide rail 20. One end of the suction tube 21 extends to the collection area and is equipped with a suction head 22. The width of the suction head 22 can be adapted to the width of the collection area after the area is reduced. The other end of the suction tube 21 is connected to the storage box 17 through a flexible tube 23. A third slide rail 24 is provided on the inner wall of the trapping box 1, which is inclined and whose vertical projection is parallel to the second slide rail 20. The suction tube 21 is slidably connected to the third slide rail 24 through a sliding claw 25.

[0032] When the drive unit 4 drives the collection plate 3 to rise until the first slide rail 7 contacts the bottom horizontal surface 11b of the guide body 11, the suction head 22 is in contact with the surface of the collection plate 3. If the drive unit 4 continues to drive the collection plate 3 to rise, it will push the guide body 11 and the suction pipe 21 to rise synchronously through the first slide rail 7 (the guide body 11 is set to be relatively heavy, so that before the first slide rail 7 contacts the bottom horizontal surface 11b of the guide body 11, the force exerted by the drive gear 13 on the inclined surface 11a of the guide body 11 is insufficient to push the guide body 11 upward; it will only cause the gathering plates 8 to overcome the elastic force of the compression spring 10 and move towards each other). This stops the two gathering plates 8 from moving towards each other, and the suction pipe 21 moves along the second slide rail 20 under the action of the third slide rail 24, thereby driving the suction head 22 to move along the collection area. At the same time, the guide body 11 drives the piston plate 16 to rise through the connecting rod 19. Figure 6This creates a negative pressure in the space below the piston plate 16, forming a high-speed airflow from the suction head 22, suction pipe 21, hose 23, storage box 17 to the suction box 15, which draws the insects in the collection area into the storage box 17.

[0033] When the drive unit 4 drives the collection plate 3 to descend, under the gravity of the guide body 11, the piston plate 16 gradually descends, and the air in the lower space of the suction box 15 is discharged through the suction head 22 in the opposite direction until it returns to its initial position. Of course, the structural design of the storage box 17 ensures that insects are not discharged with the reverse airflow. Subsequently, the collection plate 3, the gathering plate 8, etc., also return to their initial positions to prepare for the next insect collection. This allows the drive unit 4 to be set to work periodically, for example, rising and falling once every two hours, thus completing one unattended insect collection operation.

[0034] It should be noted that, in order to improve the effect, the horizontal cross-sectional area of ​​the suction box 15 needs to be large. This way, the movement of the piston plate 16 can cause a large spatial change, thereby forming a sufficient negative pressure force. The purpose of setting only one movable suction head 22 is to reduce the cross-sectional area of ​​the airflow at the suction head 22, increase the flow rate, and ensure that sufficient suction force is formed so that most insects can be sucked into the storage box 17 at one time. Of course, insects that are not collected can be collected in subsequent suction processes.

[0035] Preferably, in this invention, each guide body 11 is composed of two right-angled trapezoidal blocks, and the second slide rail 20 is mounted between the two right-angled trapezoidal blocks.

[0036] Preferably, in order to strictly prevent insects entering the storage box 17 from being expelled by airflow, the present invention provides a one-way valve at the connection between the storage box 17 and the hose 23, which allows air to enter the storage box 17 only through the hose 23; a filter screen is provided at the connection between the storage box 17 and the connecting pipe 18; and a one-way valve is provided in the lower space of the suction box 15, which allows air to be expelled only outward. In this way, when the lower space of the suction box 15 is vented, the air is directly discharged through its one-way valve and will not flow through the storage box 17. Moreover, the one-way valve of the storage box 17 is only opened when the suction is working, which can prevent insects from crawling out directly.

[0037] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
