Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The present invention provides a technical solution: a device for capturing wild gerbils alive, such as Figure 1 、 2 As shown, it includes a flap 1, a shell 2 and an elastic mechanism 20. The shell 2 is buried under the ground. The shell 2 is provided with an entrance upward, and the flap 1 is hinged at the entrance. A trigger component 30 is fixed in the flap 1, and the elastic mechanism 20 is fixed on the rear side of the shell 2. When the trigger component 30 is actuated, the elastic mechanism 20 can drive the flap 1 to rotate downward, so that the gerbil falls into the shell 2. The shell 2 is set under the ground to facilitate camouflage.

[0031] like Figure 3 、 4 As shown, the trigger assembly 30 includes a latch 31 and a tensioning mechanism 60. The latch 31 is slidably arranged at the bottom of the flap 1. One end of the latch 31 can be inserted into the shell 2. The other end of the latch 31 is connected to the rear end of the pedal 32 through a pull wire 34. The pedal 32 is hinged on the flap 1. A counterweight is fixed at the rear end of the pedal 32, and a bait hook 33 is fixed at the front end. The bait can be inserted into the bait hook 33 from the front end of the pedal 32. The tensioning mechanism 60 is fixed at the bottom of the flap 1. The tensioning mechanism 60 can tension the pull wire 34. The pull wire 34 of the trigger assembly 30 can be tensioned when needed to give the gerbil some time to relax its vigilance.

[0032] like Figure 1 、5 As shown, the shell 2 is also provided with an upper cover 3, which is connected to the shell 2 through a closing mechanism 40. When the flap 1 rotates downward, it can drive the upper cover 3 to close the entrance. The flap 1 drives the closing mechanism 40 through a transmission mechanism 50. The transmission mechanism 50 is arranged on the side of the shell 2. An outer protective cover 4 is fixed to the outside of the shell 2. The shell 2 is also provided with an upper cover 3. After the big gerbil falls into the shell 2, the upper cover 3 can close the entrance to prevent the big gerbil from being taken away by predators such as weasels. The upper cover 3 is kept closed by the elastic mechanism 20, and most of the device is buried underground, making it difficult for predators such as weasels to destroy it, thereby improving the success rate and efficiency of capturing big gerbils alive and facilitating scientific research.

[0033] In order to facilitate the driving of the flap 1, as Figure 2 As shown, the elastic mechanism 20 includes a compression spring 21 and a slider 22. One end of a transmission rod 23 is hinged on the flap 1, and the other end of the transmission rod 23 is hinged on the slider 22. The slider 22 is slidingly arranged on the rear side of the shell 2.

The adjusting rod 24 is threadedly connected to the nut seat 25, and the nut seat 25 is fixed to the rear side of the shell 2. The upper end of the adjusting rod 24 is provided with a hexagonal groove. The compression spring 21 can drive the slider 22 to slide, and then drive the transmission rod 23 to move, thereby driving the flap 1 to rotate. Using a hexagonal wrench to rotate the upper end of the adjusting rod 24 can compress or relax the compression spring 21, which is convenient for adjusting the elastic force of the compression spring 21.

[0034] In order to facilitate the tensioning of the pull wire 34, as Figure 6 、 7 As shown, the tensioning mechanism 60 includes a rope loop 61 and an electric push rod 62, the electric push rod 62 is fixed under the flap 1, the movable end of the electric push rod 62 is fixed with one end of a leaf spring 63, the other end of the leaf spring 63 is fixed under the flap 1, a long slot is provided on the leaf spring 63, the rope loop 61 is fixed with a connecting hook 64, the connecting hook 64 is slidably set in the long slot, the rope loop 61 is raised and lowered on the stud 65, the stud 65 is threadedly connected with a limiting nut, the pull wire 34 passes through the rope loop 61, the electric push rod 62 can squeeze the leaf spring 63 to deform, and then drive the rope loop 61 to descend, thereby tensioning the pull wire 34, since the height of the limiting nut determines the maximum descending amount of the rope loop 61, the maximum tensioning amount of the pull wire 34 can be changed by adjusting the height of the limiting nut, which is convenient for adjusting the maximum tensioning degree of the pull wire 34.

[0035] In order to facilitate the opening and closing of the door latch 31, as shown in FIG. Figure 8 As shown, a toggle hole is provided on the door latch 31, and a sliding groove 35 is provided on the flap 1 above the door latch 31. A pressure cover 36 is detachably provided on the sliding groove 35. After removing the pressure cover 36, a tool is used to extend into the toggle hole and slide along the sliding groove 35 to open and close the door latch 31.

[0036] In order to facilitate closing the upper cover 3, Figure 9 As shown, the closing mechanism 40 includes a closing link 41 and a crank link 42, and an A hinge seat 43 and a B hinge seat 44 are fixed on the upper cover 3. Point A on the A hinge seat 43 is hinged with one end of the closing link 41, and the other end of the closing link 41 is hinged to point B on the shell 2. Point C on the B hinge seat 44 is hinged with one end of the crank link 42, and the other end of the crank link 42 is hinged to point D on the shell 2. The four points ABCD form a parallelogram. The rotation of the closing link 41 can drive the upper cover 3 to move, and then drive the crank link 42 to rotate. The middle part of the crank link 42 is bent, which can avoid being stuck to the ground during rotation, so that the upper cover 3 can be opened and attached to the ground next to the shell 2, which is convenient for camouflage.

[0037] In order to facilitate transmission Figure 9 As shown, the transmission mechanism 50 includes an incomplete gear 51 and a roller chain 54. The incomplete gear 51 is coaxially fixed to the flap 1. The incomplete gear 51 is engaged with an input wheel 52. The input wheel 52 is rotatably arranged on the housing 2. The input wheel 52 is a double-layer structure of a gear and a sprocket. The input wheel 52 is connected to the output wheel 53 through the roller chain 54. The output wheel 53 is coaxially fixed with the closing link 41. The output wheel 53 is a double-layer structure of a gear and a sprocket. The rotation of the flap 1 can drive the incomplete gear 51 to rotate, and then drive the input wheel 52 to rotate, thereby driving the output wheel 53 to rotate. The rotation of the output wheel 53 can drive the closing link 41 to rotate.

[0038] In order to collect the big gerbils in time, Figure 2 As shown, a proximity switch 5 is fixed at the bottom of the shell 2, and the proximity switch 5 faces the slider 22. The proximity switch 5 is a common sensor that can detect whether an object is approaching without contact. The proximity switch 5 is electrically connected to the controller, and the controller can adopt a 32-bit single-chip microcomputer. The controller is electrically connected to the communication module, and the communication module can adopt a LORA communication module. The controller and the communication module are fixed in the protective compartment 14, and the protective compartment 14 is fixed on the shell 2. The controller is electrically connected to the electric push rod 62.

[0039] In order to facilitate opening the upper cover 3, Figure 1 As shown, a folding handle 13 is fixed on the upper cover 3.

[0040] In order to facilitate the collection of large gerbils, such as Figure 5 、 10As shown, a cage 9 is provided in front of the shell 2, and a one-way door 10 is provided on the side of the cage 9. The one-way door 10 can only be opened from the outside. A handle 11 is fixed on the top of the cage 9, and a front shield 12 is fixed in front of the shell 2. The cage 9 is slidably arranged in the front shield 12. An exit is provided on the front side of the shell 2, and the one-way door 10 can be aligned with the exit. The gerbil that falls into the shell 2 can enter the cage 9 through the exit and the one-way door 10, and the cage 9 can be taken out from the front shield 12 to collect the gerbil.

[0041] like Figure 1 、 2 As shown, a camera 6 is fixed on the front side of the shell 2, and the camera 6 is electrically connected to the controller. A through hole 8 is opened on the upper cover 3, and a protective cover 7 is detachably fixed on the through hole 8. When the gerbil fails to enter the cage 9 in time, the protective cover 7 is opened, and a tool is inserted into the through hole 8 to drive the gerbil into the cage 9.

[0042] Working process: First, find a path where big gerbils often appear, dig a hole near the path and bury the shell 2 and cage 9 underground, open the upper cover 3, stick it on the ground next to the shell 2, use a tool to move the latch 31, insert it into the shell 2, limit the rotation of the flap 1, insert the bait from the front end of the pedal 32 to the bait hook 33, and camouflage the above-ground part of the camouflage device.

[0043] By regularly checking the footprints of the gerbil, it is determined that the gerbil has relaxed its vigilance, and then the electric push rod 62 is used to squeeze the leaf spring 63 to deform, thereby driving the rope loop 61 to descend, thereby tightening the pull line 34.

[0044] After the gerbil triggers the pedal 32, the pull wire 34 can pull the door latch 31 out of the shell 2, and the compression spring 21 can drive the slider 22 to slide, and then drive the transmission rod 23 to move, thereby driving the flap 1 to rotate, so that the gerbil falls into the shell 2. At the same time, the rotation of the flap 1 can drive the incomplete gear 51 to rotate, and then drive the input wheel 52 to rotate, thereby driving the output wheel 53 to rotate, and the rotation of the output wheel 53 can drive the closing link 41 to rotate, and the rotation of the closing link 41 can drive the upper cover 3 to move, and then drive the crank arm link 42 to rotate, so that the upper cover 3 closes the entrance.

[0045] The proximity switch 5 detects the approach of the slider 22 and reminds the researcher to come and collect the gerbil through the communication module. When the gerbil fails to enter the cage 9 in time, the protective cover 7 is opened and a tool is inserted from the through hole 8 to drive the gerbil into the cage 9. The cage 9 is taken out from the front shield 12 to collect the gerbil. After collecting the gerbil, it is placed in a new cage 9 and camouflaged again.
