Description

Technical Field

[0001] The utility model relates to the technical field of collecting samples of birds inhabiting marmot holes, in particular to a device for collecting samples of birds inhabiting marmot holes. Background Art

[0002] Within the natural plague foci of marmots in the Qinghai-Tibet Plateau, a "bird-mice-in-the-same-burrow" phenomenon exists. This ecological niche overlap with the plague reservoir likely contributes to the long-distance transmission of plague by marmot burrow-dwelling birds through the parasitism of infected fleas. Identifying the types of fleas parasitizing marmot burrow-dwelling birds and the current status of plague infection within the foci is crucial for plague ecological research and monitoring. Sampling marmot burrow-dwelling birds is a crucial component of this monitoring effort. Common collection methods utilize various trapping tools, such as nets and bird cages, which are lowered into burrows and then manipulated with external rods to capture them. However, marmot burrows often have irregular entrances and varying depths. Therefore, fixed-length collection devices lack flexibility across different burrows and often cannot penetrate deeper, limiting sample collection efficiency. Furthermore, the narrow interiors of burrows make it difficult to adjust the length to the desired size, making sample collection inflexible and time-consuming. Customizing the device to the specific burrow size is both time-consuming and labor-intensive.

[0003] These defects directly affect the efficient collection of samples in ecological monitoring and scientific research. Therefore, a device for collecting samples of marmot hole-dwelling birds is needed to solve the above defects. Utility Model Content

[0004] The purpose of the utility model is to provide a device for collecting samples of birds living in marmot holes, so as to solve the problem of the non-adjustable size of the device proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a device for collecting samples of birds living in marmot holes, comprising a reinforcement cage and a frame, the outside of the reinforcement cage being a plurality of groups of horizontally arranged frames, the outside of the frame being welded with a plurality of groups of stirrups, the stirrups dividing the reinforcement cage into a plurality of adjustable sections, the outside of each section of the frame being sleeved with a hollow bar, the hollow bar located on the left side above the reinforcement cage and the hollow bar on the right side below the reinforcement cage being provided with threaded holes, the threaded holes being fitted with screws, and the frame and the hollow bar being connected by the screws.

[0006] Preferably, the hollow bar is a metal rod with openings at both ends, and the threaded holes are distributed at equal intervals on the frame and the hollow bar.

[0007] Preferably, a cage door is provided at the left opening of the rib cage, a coil spring is installed on the top of the cage door, a movable hook rod is installed in the middle position of the top of the rib cage, the left side of the lock hook rod is hooked to the coil spring, and the bottom end of the hook rod is hooked to a trigger mechanism.

[0008] Preferably, the height of the reinforcement cage is 18 cm and the basic length is 50 cm.

[0009] Preferably, the rib cage is hinged with a hanging rod on the outside of the left opening, the rib cage is sleeved with a membrane cloth on the outside, and the membrane cloth is tied with a rope on the hanging rod.

[0010] Preferably, a fixing rod is welded to the other end of the hanging rod, an extension rod is sleeved on the outside of the fixing rod, a sliding groove is provided in the extension rod, the fixing rod is embedded in the sliding groove and moves, and a socket is provided in both the fixing rod and the extension rod, a plug rod is plugged into the socket, and the extension rod and the fixing rod are fixed to the entrance of the marmot hole through the plug rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the device for collecting samples of marmot hole-dwelling birds not only realizes the adjustable device size, thereby improving the success rate of bird capture, but also realizes the adaptation to terrains with different slopes and hole shapes;

[0012] (1) The device is a circular cage with stirrups, a frame, hollow bars, screws, and threaded holes. The stirrups and the frame are cross-welded to form a skeleton. Each section of the frame is sleeved with a hollow bar. The two groups of hollow bars on the left and right are fixed to the threaded holes by screws. If the length of the entire cage needs to be adjusted, the screws can be rotated to release the threaded connection with the threaded holes, so that the cage can be divided into three adjustable sections. After the length is extended, it can be locked by screws. Based on the basic length of 50 cm, the adjustable structure enables the device to adapt to caves of different sizes, which not only improves the flexibility of the device, but also ensures capture in different collection environments, solving the problem that traditional equipment has a fixed length and cannot adapt to various cave depths.

[0013] (2) A layer of membrane cloth is provided on the outside of the cage by arranging a membrane cloth, a hanging rod and a lashing rope. When a bird enters from one side of the cage door and touches the trigger mechanism, the two sets of cage doors are immediately closed through the connection between the hook rod and the coil spring. A layer of membrane cloth is provided on the outside of the cage to prevent the bird from flying away. The membrane cloth is open on the left side and closed on the right side. It is covered on the outside of the cage and tied to the hanging rod by a lashing rope so that it will not fall off. The operator can easily remove the membrane cloth or put it back on the outside of the cage. When catching birds, the birds cannot escape. The cage is particularly suitable for catching bird samples with quick response capabilities, thereby improving the success rate of bird catching.

[0014] (3) By setting up a hanging rod, a hinge seat, an extension rod, an insertion rod, and a socket, an adjustable length component is set at the hanging rod. The entire hanging rod can be rotated to adapt to the external slope of the marmot hole. The extension rod is pulled outward or pushed inward, and then the insertion rod is inserted into the socket until the insertion rod is inserted into the soil at the entrance of the marmot hole and fixed. It can adapt to terrains with different slopes and hole shapes. The device forms a solid support point at the hole, ensuring stability during the collection process and preventing the device from moving or falling off. BRIEF DESCRIPTION OF THE DRAWINGS
