Description

Technical Field

[0001] The utility model relates to the technical field of gadfly catching, and more particularly to a portable gadfly catching device for grasslands. Background Art

[0002] Gadflies are a common blood-sucking insect that bites livestock and humans, causing discomfort and spreading disease. Gadflies are usually large in size, with broad, transparent wings. Their bodies are usually black or brown, sometimes with yellow, red or white spots. They feed on blood to obtain the nutrients they need for growth. They are usually active during the day, especially in the early morning and evening. In some traditional medicine, gadflies are believed to be able to break up blood and remove blood stasis, and help treat blood stasis, amenorrhea, and accumulation of tumors. Gadflies are more common in farmlands, grasslands and forest edges, and a capture device is needed to capture gadflies.

[0003] Most traditional capture devices capture gadflies by swinging a net bag at one end of a handheld long pole. However, due to the long pole of such capture devices, they take up a lot of space and are not easy to carry.

[0004] Moreover, after the net bag is used for capturing, its opening is still in an open state. If one is not careful, the horsefly will fly out from the opening, which makes it more laborious to take out the horsefly from the net bag, and easily results in wasted effort. Therefore, the net bag is not suitable for use. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a portable grassland gadfly catching device, which has the following beneficial effects:

[0018] 1. By setting two locking pins and locking slots, the user can pull the pull block to disengage the locking pin from the locking slot to rotate the hand-held rod to realize the opening and folding operation of the hand-held rod. When the hand-held rod is in the open state, the length of the device can be extended to capture gadflies in the air. When in the folded state, the space occupied by the device can be reduced, which is convenient to carry and increases practicality.

[0019] 2. By arranging a vertical plate and an electric push rod at the bottom of the mounting frame, when a gadfly is caught, the electric push rod can be controlled to move the arc-shaped clamping block to clamp the upper end of the net bag body, thereby making the opening at the upper end of the net bag body smaller. At this time, it is difficult for the gadfly inside the net bag body to find the opening, making it easier for the catcher to catch the gadfly inside the net bag body. This design can prevent the gadfly from flying out after being caught, making it easier to use.

[0020] 3. By setting the cavity, threaded rod and tightening screw, when the length of the device needs to be adjusted, the tightening screw can be loosened by twisting the block first, and then the adjusting rod can be rotated to make it extend or shorten inside the cavity through the action of the threaded rod, thereby adjusting the overall length of the device to capture gadflies of different heights. When the appropriate length is adjusted, the tightening screw can be tightened, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

The vertical plate 12 is located on both sides of the net bag body 3.

[0031] In this embodiment, an electric push rod 13 is fixed on the outer wall of the vertical plate 12, and the output end of the electric push rod 13 passes through the vertical plate 12 and is fixed with an arc-shaped clamping block 14. A rubber pad 15 is fixed on the inner wall of the arc-shaped clamping block 14. Guide rods 16 are fixed on the outer wall of the arc-shaped clamping block 14 and on both sides. Corresponding guide holes 17 are opened on the vertical plate 12, and the guide rods 16 are slidably installed with the guide holes 17.

[0032] More specifically, the user can pull the pull block 10 to disengage the locking pin 8 from the locking groove 9 to rotate the hand-held rod 6 to realize the opening and folding operation of the hand-held rod 6. When the hand-held rod 6 is in the open state, the length of the device can be extended to capture gadflies in the air. When it is in the folded state, the space occupied by the device can be reduced, making it convenient to carry. When a gadfly is caught, the arc-shaped clamping block 14 can be moved by controlling the electric push rod 13 to clamp the upper end of the net bag body 3, thereby making the opening at the upper end of the net bag body 3 smaller. At this time, the gadflies inside the net bag body 3 are not easy to find the opening, which makes it convenient for the catcher to catch the gadflies inside the net bag body 3.

[0033] See also Figure 1 、 Figure 4 and Figure 5 As an implementation method for extending the extension length of the device: a cavity 18 is opened inside the hand-held rod 6, a threaded rod 19 is fixedly provided inside the cavity 18, an adjusting rod 20 is movably provided at the outer end of the threaded rod 19 and is located inside the cavity 18, the adjusting rod 20 is threadedly connected to the threaded rod 19, a threaded hole 21 is opened on the outer wall of the hand-held rod 6 and at one end, a tightening screw 22 is provided inside the threaded hole 21, one end of the tightening screw 22 is abutted against the outer wall of the adjusting rod 20, and a twisting block 23 is fixed to one end of the tightening screw 22, and one end of the adjusting rod 20 passes through the cavity 18 and is fixed with a limit block 24.

[0034] Specifically, when the length of the device needs to be adjusted, the tightening screw 22 can be loosened by twisting the block 23, and then the adjusting rod 20 can be rotated to allow it to extend or shorten inside the cavity 18 through the action of the threaded rod 19, thereby adjusting the overall length of the device to capture gadflies of different heights.

[0035] Please refer to Figure 1 As a further implementation method for disassembling and replacing the net bag body 3: a mounting groove 25 is opened on the upper end surface of the mounting frame 1, and the mounting block 2 is movably located inside the mounting groove 25.

[0036] Specifically, the net bag body 3 can be installed and disassembled through the installation slot 25, which is convenient for replacement.

[0037] In summary, when the overall device is in use: the user can pull the pull block 10 to disengage the locking pin 8 from the locking groove 9 to rotate the hand-held rod 6 to realize the opening and folding operation of the hand-held rod 6. When the hand-held rod 6 is in the open state, the length of the device can be extended to capture gadflies in the air by waving the net bag body 3. When a gadfly is caught, the arc-shaped clamping block 14 can be moved by controlling the electric push rod 13 to clamp the upper end of the net bag body 3, thereby making the opening at the upper end of the net bag body 3 become closed. The opening is small, and the gadflies inside the net bag body 3 are not easy to find, which makes it easier for the catcher to catch the gadflies inside the net bag body 3. When in the folded state, the space occupied by the device can be reduced, making it easier to carry. When the length of the device needs to be adjusted, the tightening screw 22 can be loosened by twisting the block 23, and then the adjusting rod 20 can be rotated to make it extend or shorten inside the cavity 18 through the action of the threaded rod 19, thereby adjusting the overall length of the device to capture gadflies of different heights.
