[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 7 , and the above technical solutions of the present utility model will be described in detail through the following embodiments:

[0028] A forestry pest sample collection device, comprising: a trapping cylinder 1; a trapping cover 2 is threadedly connected to the outer surface of the top of the trapping cylinder 1, six food luring grooves 3 are arranged inside the trapping cover 2, and the food luring grooves 3 are fixedly connected to the trapping cover 2, a through hole 4 is opened at the center of the circle of the middle part of the trapping cover 2; a rotating mechanism 5 for capturing pests is arranged near the through hole 4 of the trapping cover 2; a locking mechanism 6 for quickly installing the device on the surface of a tree is arranged on one side of the trapping cylinder 1; a disassembly and assembly mechanism 7 for quickly docking the trapping cover 2 with the trapping cylinder 1 is arranged near the trapping cover 2 of the trapping cylinder 1. The user docks the trapping cover 2 with the trapping cylinder 1 through the disassembly and assembly mechanism 7, then fixes the device on the outer surface of the tree through the locking mechanism 6 and adds a food luring agent inside the food luring grooves 3 at the same time, and finally captures the pests lured by the food luring agent into the trapping cylinder 1 through the rotating mechanism 5 for storage, so that the device can lure pests with different volumes and can capture the lured pests, enabling the pests to enter the trapping cylinder 1 for storage, solving the problem that the existing collection device is provided with a plurality of electrical components to detect pests and then push the pests into the device, but due to the small volume of some pests, the electrical components cannot detect the existence of the pests, and thus cannot assist the pests to enter the collection device.

[0029] Such as Figure 1 , Figure 2 Figure 5 and Figure 6As shown in the figure, the rotating mechanism 5 includes: a rotating cover 8 is arranged near the through hole 4 of the trapping cover 2. An inlet 9 is provided on one side of the rotating cover 8. A protective cover 10 is fixedly connected to one side of the rotating cover 8 near the inlet 9. A baffle 11 is fixedly connected to one side of the bottom of the protective cover 10. A first rotating shaft 12 is fixedly connected to the center of the top of the rotating cover 8. The end of the first rotating shaft 12 away from the rotating cover 8 penetrates through the circular plate 13 and extends to the motor 14. L-shaped rods 15 are fixedly connected to the four corners of the circular plate 13. The ends of the L-shaped rods 15 away from the circular plate 13 are fixedly connected to the trapping cover 2. The motor 14 is fixedly connected to the circular plate 13. The first rotating shaft 12 is fixedly connected to the output end of the motor 14. When the motor 14 is started, the motor 14 operates through the cooperation of the circular plate 13 and the L-shaped rods 15. While the motor 14 is operating, the rotating cover 8 is driven to rotate by itself through the first rotating shaft 12. While the rotating cover 8 rotates, the protective cover 10 and the baffle 11 are driven to rotate in a circle. While the protective cover 10 and the baffle 11 are rotating in a circle, the pests lured by the luring agent in the luring groove 3 are pushed into the inside of the rotating cover 8 from the inlet 9 on one side of the rotating cover 8. The pests that enter the inside of the rotating cover 8 enter the inside of the trapping cylinder 1 through the through hole 4 for storage. This enables the device to lure pests of different volumes and capture the lured pests, allowing the pests to enter the inside of the trapping cylinder 1 for storage, solving the problem that in the existing collection device, there are multiple electrical components inside to detect pests and then push the pests into the inside of the device. However, due to the small volume of some pests, the electrical components cannot detect the presence of pests, and thus cannot assist the pests to enter the inside of the collection device.

[0030] As Figure 7As shown in the figure, the locking mechanism 6 includes: on one side of the trapping cylinder 1, two first arc-shaped connecting rods 16 are fixedly connected. One end of the first arc-shaped connecting rod 16 is fixedly connected with a second rotating shaft 17. The outer surface of the second rotating shaft 17 is rotatably connected with a second arc-shaped connecting rod 18. One end of the first arc-shaped connecting rod 16 and the second arc-shaped connecting rod 18 far from the second rotating shaft 17 are both fixedly connected with a fixing plate 19. U-shaped grooves 20 are respectively opened inside the fixing plates 19. On one side of one of the fixing plates 19, there is a nut 21. On one side of the other fixing plate 19, there is a locking knob 22. One end of the locking knob 22 passes through the U-shaped groove 20 and extends to the nut 21. The locking knob 22 is threadedly connected with the nut 21. The user first separates the locking knob 22 from the nut 21, then rotates the second arc-shaped connecting rod 18 through the second rotating shaft 17. After sleeving the first arc-shaped connecting rod 16 on the surface of the tree, the second arc-shaped connecting rod 18 is rotated in the reverse direction. Finally, one end of the locking knob 22 is connected with the nut 21 through the U-shaped groove 20 inside the fixing plate 19. When the locking knob 22 rotates, the distance between the nut 21 and the locking knob 22 decreases. The nut 21 and the locking knob 22 squeeze the fixing plate 19. The fixing plate 19 drives the first arc-shaped connecting rod 16 and the second arc-shaped connecting rod 18 respectively, so that the diameter between the first arc-shaped connecting rod 16 and the second arc-shaped connecting rod 18 decreases, and further makes the first arc-shaped connecting rod 16 and the second arc-shaped connecting rod 18 closely fit on the surface of the tree, achieving the purpose of fixing the device on the surface of the tree.

[0031] As Figure 4 shown, the disassembly and assembly mechanism 7 includes: several ball grooves 23 are evenly opened near the trapping cover 2 close to the trapping cylinder 1. Steel balls 24 are respectively arranged inside the ball grooves 23. A pressing ring 25 is slidably connected to the trapping cover 2 near the steel balls 24. A connecting ring 26 is fixedly connected to the outer surface of the pressing ring 25. A force-applying ring 27 is fixedly connected to the outer surface of the connecting ring 26. A clamping groove 28 is opened near the steel balls 24 on the trapping cylinder 1. An activity groove 29 is opened on the inner wall of the pressing ring 25. The clamping groove 28 and the activity groove 29 are both adapted to the steel balls 24. The user pushes the force-applying ring 27 upward. The force-applying ring 27 drives the connecting ring 26, and the connecting ring 26 drives the pressing ring 25, so that the activity groove 29 on the pressing ring 25 moves to the ball groove 23, increasing the moving range of the steel balls 24. The user can then separate the trapping cover 2 from the trapping cylinder 1.

[0032] As Figure 4As shown, a spring 30 is provided at the top of the extrusion ring 25. The spring 30 is arranged inside the trapping cover 2. When the user needs to dock the trapping cover 2 with the trapping cylinder 1, the trapping cover 2 is sleeved on the outer surface of the top of the trapping cylinder 1, and then the force - applying ring 27 is released. When the user releases the force - applying ring 27, elastic recovery occurs, which then pushes the extrusion ring 25 downward. When the extrusion ring 25 moves, it drives the separation of the movable groove 29 from the ball groove 23 and squeezes the steel ball 24, causing a small part of the steel ball 24 to move into the card slot 28 on the surface of the trapping cylinder 1, thus achieving the purpose of docking the trapping cover 2 with the trapping cylinder 1.

[0033] As Figure 4 shown, a damping pad 31 is provided on the outer surface of the force - applying ring 27. The damping pad 31 is fixedly connected to the force - applying ring 27, which increases the roughness of the surface of the force - applying ring 27, thereby facilitating the user to apply force to the force - applying ring 27 and avoiding the phenomenon of slipping.

[0034] As Figure 3 shown, a funnel 32 is arranged inside the through - hole 4. The funnel 32 is fixedly connected to the trapping cover 2. A number of triangular teeth 33 are evenly arranged at the bottom of the funnel 32, and the triangular teeth 33 are all fixedly connected to the funnel 32. When the pests entering the through - hole 4 come into contact with the inclined surface inside the funnel 32, the pests will slide into the inside of the trapping cylinder 1 for storage. And the setting of the triangular teeth 33 can prevent the pests entering the inside of the trapping cylinder 1 from escaping.

[0035] Working principle: The user first separates the locking knob 22 from the nut 21, then rotates the second arc-shaped connecting rod 18 through the second rotating shaft 17. After sleeving the first arc-shaped connecting rod 16 on the surface of the tree, the second arc-shaped connecting rod 18 is rotated in the reverse direction. Finally, one end of the locking knob 22 is connected to the nut 21 through the U-shaped groove 20 inside the fixing plate 19. When the locking knob 22 rotates, the distance between the nut 21 and the locking knob 22 decreases, and the nut 21 and the locking knob 22 squeeze the fixing plate 19. The fixing plate 19 drives the first arc-shaped connecting rod 16 and the second arc-shaped connecting rod 18 respectively, so that the diameter between the first arc-shaped connecting rod 16 and the second arc-shaped connecting rod 18 decreases, and then the first arc-shaped connecting rod 16 and the second arc-shaped connecting rod 18 closely fit on the surface of the tree, achieving the purpose of fixing the device on the surface of the tree. At the same time, a bait agent is added to the bait groove 3. Finally, the motor 14 is started. The motor 14 operates through the cooperation of the circular plate 13 and the L-shaped rod 15. While the motor 14 operates, it drives the rotating cover 8 to rotate self-rotation through the first rotating shaft 12. While the rotating cover 8 rotates, it drives the protective cover 10 and the baffle 11 to rotate in a circle. While the protective cover 10 and the baffle 11 rotate in a circle, the pests lured by the bait agent in the bait groove 3 are pushed into the inside of the rotating cover 8 from the inlet 9 on one side of the rotating cover 8. The pests entering the inside of the rotating cover 8 enter the inside of the trapping cylinder 1 through the through holes 4 for storage, enabling the device to lure pests of different volumes and capture the lured pests, so that the pests enter the inside of the trapping cylinder 1 for storage, solving the problem that there are multiple electrical components inside the existing collection device to detect pests and then push the pests into the inside of the device. However, due to the small volume of some pests, the electrical components cannot detect the existence of pests, and thus cannot assist the pests to enter the inside of the collection device.

[0036] The user pushes the force - applying ring 27 upward. The force - applying ring 27 drives the connecting ring 26, and the connecting ring 26 drives the extrusion ring 25, so that the movable groove 29 on the extrusion ring 25 moves to the ball groove 23, increasing the movement range of the steel balls 24. Then the user can separate the trapping cover 2 from the trapping cylinder 1. When the user needs to dock the trapping cover 2 with the trapping cylinder 1, the user sleevs the trapping cover 2 on the outer surface of the top of the trapping cylinder 1, and then releases the force - applying ring 27. When the user releases the force - applying ring 27, elastic recovery occurs, which then pushes the extrusion ring 25 downward. When the extrusion ring 25 moves, it drives the movable groove 29 to separate from the ball groove 23 and squeezes the steel balls 24, so that a small part of the steel balls 24 moves into the clamping groove 28 on the surface of the trapping cylinder 1, thus achieving the purpose of docking the trapping cover 2 with the trapping cylinder 1. The user can quickly separate and dock the trapping cover 2 and the trapping cylinder 1, which is convenient for the user to open the trapping cover 2 to process and sample the pests stored inside the trapping cylinder 1. And when the trapping cover 2 is docked with the trapping cylinder 1, the docking is stable, avoiding the situation that the pests trapped inside the trapping cylinder 1 escape due to the separation of the trapping cover 2 and the trapping cylinder 1.

[0037] Finally, it should be noted that: the above - mentioned embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention.
