Description

Technical Field

[0001] The utility model relates to the technical field of Chinese tussah silkworm breeding, in particular to an insect attracting device for Chinese tussah silkworm breeding. Background Art

[0002] The main diseases in the process of Chinese tussah silkworm breeding include Chinese tussah nuclear polyhedrosis or Chinese tussah septicemia, Chinese tussah microsporidiosis, empty body disease, Chinese tussah tachina fly disease or maggots disease, and nematode disease. Among them, in the breeding process, the tachina fly disease is relatively serious. Therefore, in the process of Chinese tussah silkworm breeding, an insect attracting device is mostly needed to trap tachina flies.

[0003] Most of the existing insect attracting devices mostly adhere to the flying flies through adhesives. However, such a trapping method is limited by the area coated with the adhesive. At the same time, the adhesive is exposed to the air for a long time, and its adhesive performance will gradually decrease, making it impossible to achieve long-term insect attraction. There are also some that seal the flies in a container space so that they cannot fly out of the container. However, such a trapping method is more troublesome for personnel to clean. Some flies that are not dead will fly out when the personnel open the cover for cleaning, and the insect killing effect is poor.

[0004] Therefore, it is necessary to provide an insect attracting device for Chinese tussah silkworm breeding to solve the above technical problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose an insect attracting device for Chinese tussah silkworm breeding.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: An insect attracting device for Chinese tussah silkworm breeding, including a water storage tray. A water storage groove is opened at the top of the water storage tray. A communicating pipe is fixedly connected to the bottom of the inner wall of the water storage groove. An expansion ring is installed at the top end of the communicating pipe. A communicating groove is opened inside the communicating pipe. A tapered groove opening downward is opened at the bottom of the water storage tray. The communicating groove is communicated with the tapered groove. The top end of the expansion ring expands outward. A water source is arranged inside the water storage groove. The expansion ring is used to prevent the falling flies from climbing upward after contacting the communicating pipe. A threaded connection slot is arranged at the top end of the water storage tray for the threaded connection and installation of a cover. The diameter of the bottom end of the tapered groove is larger than that of the placement tray.

[0007] As a further description of the above technical scheme:

[0008] Three connecting brackets are fixedly connected to the bottom of the water storage tray. The other ends of the three connecting brackets are fixedly connected to an installation ring. An internal thread groove B is opened inside the installation ring. The three connecting brackets are all of U-shaped structures and are evenly distributed in a ring centered on the tapered groove. The installation ring is arranged directly below the tapered groove.

[0009] As a further description of the above technical solution:

[0010] The internal thread of the internal thread groove B is connected with a connecting pipe, the interior of the connecting pipe is provided with a mounting groove, the outside of the connecting pipe is fixedly connected with a limiting ring, and a threaded structure is provided on the outside of the connecting pipe and above the limiting ring for threaded connection with the internal thread groove B. The limiting ring is installed in the middle position of the connecting pipe.

[0011] As a further description of the above technical solution:

[0012] A bearing is arranged inside the mounting groove.

[0013] As a further description of the above technical solution:

[0014] A placing plate is provided on the top of the rotating part of the bearing, and a placing groove is provided on the top of the placing plate. The interior of the placing groove is used for placing insect attractants to attract flies and insects.

[0015] As a further description of the above technical solution:

[0016] A fixing rod is fixedly connected to the bottom of the placement plate, and three blades are fixedly connected to the bottom end of the fixing rod. The three blades are fixed in a ring shape and are used to drive the placement plate to rotate as the wind blows. As the external wind blows, the blades are driven to rotate the fixing rod connected to the placement plate, thereby startling the flies and insects staying above, causing the frightened flies and insects to fly upwards.

[0017] As a further description of the above technical solution:

[0018] The top of the water storage tray is threadedly connected with a blocking cover, the top of the blocking cover is provided with a transfer hole, and the outside of the blocking cover is provided with a plurality of air leakage holes in a ring shape, and the air leakage holes are relatively narrow and are used to increase the dissemination direction of the insect attractant.

[0019] As a further description of the above technical solution:

[0020] A hook connecting rod is installed inside the adapter hole, and two annular limiting plates are fixedly connected to the outside of the hook connecting rod. An internal thread groove A is opened on the top of the hook connecting rod, and the internal thread of the internal thread groove A is connected with a hook. The two annular limiting plates are respectively located above and inside the blocking cover, and the hook can be disassembled by threads.

[0021] The utility model has the following beneficial effects:

[0022] 1. Compared with the prior art, in this insect attracting device for tussah silkworm breeding, the water storage tank on the top of the water storage tray is filled with water source. After installing the hook, the whole insect attracting device is hung on the branch or other hanging places at the using location. When fly insects are attracted by the insect attractant in the placing groove and move there, when they fly upward, they pass through the connecting groove and enter under the blocking cover, and cannot fly out continuously. When their physical strength is insufficient or they fly randomly and descend, they fall into the lower water storage tank and are adhered by the water source to complete the capture. By using the capture method of water source, not only the cost is relatively low, but also a large number of fly insects can be accommodated, and when cleaning, the staff only needs to pour out the water source, which is convenient and fast for cleaning.

[0023] 2. Compared with the prior art, in this insect attracting device for tussah silkworm breeding, when fly insects stay on the insect attractant in the placing groove, with the blowing of the external wind, the blades are driven to make the fixed rod connect the placing tray to rotate, thereby startling the fly insects staying above, making the startled fly insects fly upward, and further improving the capture ability of fly insects;

[0024] At the same time, when the using location is not convenient for hanging the insect attracting device, the insect attracting device can also be directly placed on a relatively high ground and supported by the connecting bracket, effectively improving the applicable range of the device.
