DETAILED DESCRIPTION

[0024] Embodiment 1

[0025] like Figure 1-Figure 4As shown, a parasitic bee release and supply device proposed by the utility model includes a top cover 1, an attractant release component, a base 7 and a limit component. The top of the top cover 1 is connected to a hook 2, which is a snap-on hook, and the bottom of the top cover 1 is connected to a protective cover 6, on which a through hole 602 is provided, and a plurality of parasitic bee release holes 603 are provided, the parasitic bee release holes 603 are connected to the outside and the through hole 602, and the protective cover 6 is provided with an annular groove C604 connected to the through hole 602. The attractant release component includes a material-absorbing cotton 5, which is connected to the top cover 1 and surrounds the outer side of the protective cover 6. A storage bin 102 is arranged inside the top cover 1, and a feeding port 103 connected to the storage bin 102 is arranged on the top of the top cover 1, and an annular groove B104 connected to the storage bin 102 is arranged on the bottom of the top cover 1, and a plurality of odor release holes 105 connected to the annular groove B104 are arranged at the bottom of the top cover 1, and the odor release holes 105 surround the peripheral side of the protective cover 6. A sealing plate 4 is arranged at the upper end opening of the annular groove B104, and a plurality of micro-leakage holes 401 connecting the storage bin 102 and the annular groove B104 are arranged on the sealing plate 4. The material-absorbing cotton 5 is located in the annular groove B104. An annular groove A101 is arranged on the arc surface of the top cover 1, and the annular groove A101 is connected to the feeding port 103, and an annular cover 3 is slidably arranged in the annular groove A101, and a feeding port 301 is arranged on the annular cover 3. The base 7 is inserted into the protective cover 6 along the bottom thereof and is slidably connected thereto, and a storage tank 701 is arranged on the base 7, and a nutrition incubator 8 is arranged in the storage tank 701. The limiting assembly includes a slider 9 and a wedge-shaped block 13. A storage tank 702 opening downward is arranged on the base 7, and a side hole 703 communicating with the storage tank 702 is arranged on the base 7. The slider 9 is located in the storage tank 702 and is slidably connected to its inner wall. One end of the wedge-shaped block 13 extends out of the side hole 703, and the other end is inserted into the slider 9 along the side hole 703 and is slidably connected thereto, and a tensioning assembly for pushing the wedge-shaped block 13 outward is arranged in the slider 9. When the base 7 is inserted into the protective cover 6, the wedge-shaped block 13 automatically pops out and is stuck in the annular groove C604. When the slider 9 is pushed upward, the wedge-shaped block 13 automatically retracts into the slider 9 when its inclined surface contacts the upper wall of the side hole 703. A handle 10 is disposed in the storage groove 702, and the handle 10 is connected to a slide rod 11, which passes through the slider 9 and is slidably connected thereto, and a tensioning spring 12 is sleeved on the outside of the slide rod 11, and two ends of the tensioning spring 12 are respectively abutted against the upper wall of the storage groove 702 and the upper surface of the handle 10.

[0026] In this embodiment, the annular cover 3 is first rotated to make the feed port 301 correspond to and communicate with the feed port 103, and then a proper amount of attractant is added to the storage bin 102, and then the annular cover 3 is slid to close the feed port 103 again, and the attractant slowly seeps down through the micro-leak hole 401 and is absorbed by the absorbent cotton 5, and the attractant absorbed by the absorbent cotton 5 evaporates along the odor release hole 105. Then, the parasitic bee eggs are placed on the nutrition incubator 8 in the storage tank 701 of the base 7, and then the base 7 is pushed upward along the bottom of the through hole 602 until the wedge-shaped block 13 is stuck in the annular groove C604, and finally the device is hung on the branches of the plant at an appropriate height through the hook 2. When the eggs are hatched, the parasitic bees crawl toward the parasitic bee release hole 603 under the attraction of the attractant odor and finally fly out of the device from the parasitic bee release hole 603. When it is necessary to add attractant, one only needs to rotate the annular cover 3 again to connect the feeding port 301 with the feeding port 103. When it is necessary to add insect eggs, one only needs to hold the handle 10 and then push up the slider 9. At this time, the slider 9 slides up so that the inclined surface of the wedge-shaped block 13 contacts the upper wall of the side hole 703 and then retracts into the slider 9, thereby releasing the clamping limit relationship between the wedge-shaped block 13 and the annular groove C604. The base 7 can be directly pulled out from the protective cover 6, and the operation is simple and convenient.
