[0025] like Figure 1 and Figure 2 A sweet potato weevil rearing device includes an incubator 1, which is existing technology. It is opaque, has a dark interior, and is equipped with a temperature and humidity control mechanism to regulate the temperature and humidity inside the incubator 1. The incubator 1 is equipped with multiple rearing mechanisms, including a first black cylinder 2 and a second black cylinder 3 made of polyethylene. The second black cylinder 3 is located inside the first black cylinder 2, and the interior of the second black cylinder 3 is used for rearing the sweet potato weevils.

[0026] like Figure 1 , Figure 2 and Figure 4 The bottom of the inner wall of the incubator 1 is rotatably connected to a support base 4, and the top of the support base 4 is fixedly connected to a fixing rod 5. The top of the fixing rod 5 passes through the top of the incubator 1 and is fixedly connected to a rotating ring 6. The rotating ring 6 is provided with multiple indicator rings 601. The number of indicator rings 601 is the same as that of the bearing grooves 7, and they are set one-to-one. Each indicator ring 601 has a different mark, which can distinguish its corresponding bearing groove 7 and the first black cylinder 2 on the bearing groove 7. The top of the support base 4 is provided with a bearing groove 7 in a ring array. The bearing groove 7 and the bottom of the first black cylinder 2 are adapted to fit into the bearing groove 7, so that the bottom of the first black cylinder 2 can be inserted into the bearing groove 7.

[0027] like Figure 1 and Figure 2The bottom of the inner wall of the second black cylinder 3 is provided with a fine sand layer 8 with a thickness of 2cm. The fine sand layer 8 is fine sand that has been dried and sterilized. A potato block 9 is placed on top of the fine sand layer 8. The mass of the potato block 9 is 300g (the error is controlled within 10g).

[0028] like Figure 2 and Figure 3 The top of the first black cylinder 2 is provided with a first mesh 201. The radius of the first mesh 201 is larger than the radius of the first black cylinder 2. The bottom of the first mesh 201 is bent downward and attached to the surface of the first black cylinder 2. The outer surface of the first black cylinder 2 is covered with a first rubber band 202. The first rubber band 202 tightly covers the top of the first black cylinder 2 with the first mesh 201.

[0029] like Figure 2 and Figure 3 The top of the second black cylinder 3 is provided with a second mesh 301. The radius of the second mesh 301 is larger than the radius of the second black cylinder 3. The bottom of the second mesh 301 is bent downward and attached to the surface of the second black cylinder 3. A second rubber band 302 is sleeved on the outer surface of the second black cylinder 3. The second rubber band 302 tightly sleeves the second mesh 301 on the top of the second black cylinder 3.

[0030] like Figure 2 The first black cylinder 2 has an upper diameter of 30cm, a lower diameter of 25cm, and a height of 30cm; the second black cylinder 3 has an upper diameter of 25cm, a lower diameter of 20cm, and a height of 25cm.

[0031] like Figure 2 and Figure 3 The first mesh 201 and the second mesh 301 are both 100 mesh, which are used to close the top of the first black cylinder 2 and the top of the second black cylinder 3 respectively, to achieve double sealing and prevent the sweet potato weevil from detaching from the second black cylinder 3.

[0032] like Figure 1 The top of the incubator 1 is provided with an incubation port, and a closed top cover 11 is provided on the incubation port. The closed top cover 11 can be opened upwards to facilitate the placement or removal of the feeding mechanism composed of the first black cylinder 2 and the second black cylinder 3 into the incubator 1.

[0033] The working principle of the sweet potato weevil feeding device provided by this utility model is as follows:

[0034] When raising sweet potato weevils, place 200 newly emerged sweet potato weevils into a second black cylinder 3, and then place the second black cylinder 3 into a first black cylinder 2. Seal the openings of the second black cylinder 3 and the first black cylinder 2 with a mesh to prevent the sweet potato weevils from escaping. Then place the second black cylinder 3 into an incubator 1. The conditions in incubator 1 are: temperature 28℃, humidity 70%, darkness. Replace the sweet potato tubers with fresh ones every day. After 10 days of continuous replacement, kill all the adult weevils. Place all the replaced sweet potato tubers into a new breeding device and put it into incubator 1 to wait for the adult weevils to emerge. Then repeat the above steps, setting up a new breeding device every 10 days. Set up multiple breeding devices and continuously cycle through them to continuously breed a large number of sweet potato weevils.

[0035] Open the closed top cover 11 and manually rotate the rotating ring 6. The fixed rod 5 will drive the support base 4 to rotate. The support base 4 will drive the different first black cylinders 2 to rotate to the bottom of the top opening of the incubator 1. The indicator ring 601 closest to the top opening of the incubator 1 indicates that the corresponding group of feeding mechanisms on the corresponding bearing groove 7 has rotated to the bottom of the top opening of the incubator 1. Rotating the rotating ring 6 will move the indicator ring 601 to the position closest to the top opening of the incubator 1, so that the corresponding group of feeding mechanisms can be quickly taken out.

[0036] Compared with related technologies, the sweet potato weevil feeding device provided by this utility model has the following beneficial effects:

[0037] This invention features multiple feeding mechanisms consisting of a first black cylinder 2 and a second black cylinder 3 inside an incubator 1. Sweet potato weevils are raised in the first black cylinder 2. Each feeding mechanism can be independently removed from the incubator 1, enabling the continuous breeding of a large number of sweet potato weevils. Furthermore, the corresponding design of the indicator ring 601 and the bearing groove 7 ensures that each feeding mechanism in the bearing groove 7 corresponds to an indicator ring 601, facilitating the grouping of each feeding mechanism. The corresponding feeding mechanism can be quickly and accurately removed using the indication of the indicator ring 601.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
