Description

Technical Field

[0001] The utility model relates to the technical field of animal catching equipment, in particular to a device combination for live catching of underground mice in meadows and grasslands. Background Art

[0002] Rodents refer to mammals of the order Rodentia. Due to their diverse species, large numbers, strong adaptability, vigorous reproduction, rapid sexual maturity, high litter size, and several to dozens of offspring per litter, they seriously harm the grassland ecological environment through activities such as eating forage, digging holes to build hills, and gnawing roots. Strengthening grassland rodent control can promote grassland ecological stability and sustainable development. Therefore, strengthening the monitoring of grassland rodent damage and disaster prediction is related to grassland degradation control and restoration and stable recovery of grassland ecosystems. Live capture is the primary prerequisite for studying rodent categories, population dynamics, community structure characteristics, etc. The current method used for live capture of ground rodents is mainly cage trapping, and the equipment for live capture of underground rodents is extremely small. Due to the unique underground conditions, underground rodents have degraded vision and sensitive sense of smell. Therefore, cage trapping and live capture are not suitable for live capture of underground rodents. In addition, the live capture process is susceptible to many external factors and has high human and material costs. Utility Model Content

[0003] In order to solve the above technical problems, the utility model proposes a device combination for live capture of underground rats in meadow grasslands, which greatly reduces the input of manpower and material resources and maximizes the success rate of live capture of underground rats.

[0004] A device combination for live capture of meadow steppe subterranean rats, comprising:

[0005] A probe is used to pierce the soil layer to find out the rat hole passages where underground rats are active;

[0006] Soil layer sampler, used to strip the soil above the rat hole channel found by the probe;

[0007] A crescent-shaped cutter is used to cut off the soil core after the soil sampler strips the soil layer;

[0008] A toothless arch-shaped live-trap device for catching underground rats alive;

[0009] The probe, the soil layer sampler, the crescent-shaped cutter and the toothless arch-shaped live-capturing device can be used in conjunction with each other to capture meadow steppe subterranean mice.

[0010] Moreover, the bottom end of the probe is integrally connected with a flat portion, and the front end of the probe is integrally connected with a pancake portion.

[0011] When in use, the flat part of the probe is brought into contact with the ground vertically, and pressure is applied to the pancake-shaped part to allow the probe to be inserted into the ground;

[0012] The flat part at the bottom of the probe is designed to produce a uniform resistance when piercing the soil layer. When piercing the rat hole passage, there is no resistance at all, thus forming a sense of frustration, so the location of the rat hole passage can be found;

[0013] The design of the pancake-shaped portion at the top of the probe can increase the force-bearing area, so that the probe can be inserted into the soil with only a small amount of force during the process of detecting rat holes.

[0014] Moreover, the soil layer soil extractor comprises an inverted circular platform soil extracting bucket, a traction rod, and a handrail, one end of the traction rod is fixed to both sides of the top side wall of the inverted circular platform soil extracting bucket, and the other end of the traction rod is fixedly connected to the handrail.

[0015] Moreover, a foot pedal is detachably provided on one side of the top surface of the inverted round platform soil bucket, and the foot pedals are two and symmetrically arranged in a semicircle, and the size of the two foot pedals is adapted to the size of the top surface of the inverted round platform soil bucket;

[0016] Cutting holes are symmetrically provided below the side wall of the inverted circular table soil taking bucket, and the width of the cutting holes is adapted to the thickness of the crescent-shaped cutting knife.

[0017] Moreover, the crescent-shaped cutter comprises a crescent blade and a handle, and the crescent blade and the handle are fixedly connected; the width of the cutting hole is adapted to the thickness of the crescent blade.

[0018] Moreover, the inverted circular table soil bucket is composed of two semi-circular table buckets, one side of the two semi-circular table buckets is rotatably connected through a rotating shaft, and the other side of the two semi-circular table buckets is clamped together through a buckle.

[0019] After using the probe to find the specific location of the rat hole channel, place one side of the bottom of the inverted round platform soil bucket vertically on the soil above the rat hole channel, apply downward force in the vertical direction of the foot pedal, and vertically cut the inverted round platform soil bucket into the soil layer. Hold the handrails tightly with both hands, apply force inward with the palms facing each other, and lift the soil layer soil extractor upward to peel off the soil layer;

[0020] Then use a crescent-shaped cutter to insert into the cutting holes on both sides of the soil sampler to cut off the deep soil core, then loosen the buckle, open the soil sampler, and take out the vegetation crust layer.

[0021] Moreover, the toothless arch-shaped live capture device comprises a mousetrap, a fiber rope and a fiber nail, wherein the mousetrap is connected to the fiber nail through the fiber rope;

[0022] The mousetrap comprises a spiral elastic ring, two bow-shaped clips and a trapping device; the side of the spiral elastic ring at a higher position when in a free state is fixedly connected to a limiting ring; the side of the spiral elastic ring at a lower position when in a free state is fixedly connected to a bearing seat; one end of the two bow-shaped clips passes through the limiting ring and is rotatably connected to the bearing seat through the same rotating shaft;

[0023] When the spiral elastic ring is in a free state, the limiting ring brings the two bow-shaped clamps together; when the spiral elastic ring is in a compressed state, the limiting ring is freely sleeved on the bearing seat.

[0024] Moreover, the trapping device comprises a mouse pedal, a lever and a lever socket; the bearing seat is rotatably connected to a transfer shaft, and the mouse pedal is rotatably connected to the mousetrap through the transfer shaft;

[0025] The lever socket is fixedly connected to the spiral elastic ring, and a lever is rotatably connected to the lever socket;

[0026] A convex seat is connected to the center of the mouse pedal, and a plug hole is provided on the convex seat. The width of the plug hole is matched with the diameter of the lever.

[0027] When in use, after the soil layer is peeled off with a soil layer extractor, the rat hole passage is exposed, and the toothless arch-shaped live-trapping device is set in the rat hole passage, and then the toothless arch-shaped live-trapping device is covered with fine soil to ensure that no odor is retained, and then the vegetation crust layer is backfilled and the gap is sealed with fine soil; when an underground rat passes through, the toothless arch-shaped live-trapping device is induced to start, and the toothless arch-shaped live-trapping device captures the underground rat alive. The struggle of the underground rat drives the fiber rope and fiber nail to move, and the staff can know that the underground rat is successfully captured alive.

[0028] The method of using the toothless bow-shaped live capture device is as follows: press the two bow-shaped clamps downward, the limit ring is freely mounted on the bearing seat without affecting the use of the device, and the lever is plugged into the socket of the lever socket. At this time, the two bow-shaped clamps are fixed. When an underground rat passes by, the underground rat steps on the rat pedal, the rat pedal flips, the limit of the lever is released, and the spiral elastic ring rebounds due to its spiral stress, driving the bow-shaped clamp on the same side to flip upward. At the same time, the limit ring drives the bow-shaped clamp on the other side to flip upward, and the underground rat is clamped.

[0029] Moreover, an arc-shaped protrusion made of rubber material is fixed on the bow-shaped clamp.

[0030] The arc-shaped protrusions of the rubber material will not harm the life of the underground rat, thereby achieving the effect of live capture.

The device combination for catching underground rats alive mainly consists of a probe, a soil layer extractor, a crescent-shaped cutter, and a toothless arch-shaped live-catching device. Firstly, the probe is used to follow the periphery of a mound formed by underground rats arching the soil to find out the rat hole passage, and to find out the rat hole passage where underground rats often move. Secondly, the soil layer extractor is used to take out the upper soil of the rat hole passage in an inverted truncated cone shape, and then the crescent-shaped cutter is used to cut off the soil at the bottom of the soil layer and retain the vegetation crust layer. Then, the toothless arch-shaped live-catching device is used to remove the soil from the lower soil layer and retain the vegetation crust layer. The capture device is laid at the bottom of the rat hole channel, and the toothless bow-shaped clamp is covered with fine soil to ensure that no odor is retained. Finally, the toothless bow-shaped live capture device and the fiber nail are connected with a fiber rope. The fiber nail is fixed to the ground at a 45° angle to the vertical plane of the rat hole. The vegetation crust layer is backfilled and the gap is sealed with fine soil. When an underground rat induces the toothless bow-shaped live capture device to start, the toothless bow-shaped live capture device will capture the underground rat alive.
