The exhaust mechanism 9 includes a casing 92 , a connecting pipe 94 , a collection box 96 , a fan 97 and a filter bag 98 . The casing 92 is installed at the bottom of the casing 2 and a collection cavity 922 is formed inside the casing 92 , and the collection cavity 922 communicates with the air hole 27 . The connection pipe 94 is installed on the housing 92 and communicates with the collection cavity 922 through the communication hole 942 on the connection pipe 94 . One end of the connecting pipe 94 is installed on the collection box 96 . The filter bag 98 is arranged in the collecting box 96 and communicated with the connecting pipe 94 . The fan 97 is mounted on the collection box 96 . When blower fan 97 was running, the air in the housing 2 entered the filter bag 98 through the bottom of the ovum collection drawer 8, the vent hole 27 on the bottom wall of the housing 2, the collection cavity 922 and the connecting pipe 94, and then filtered through the filter bag 98. discharged to the external environment. During this process, a negative pressure is formed in the housing 2, and the scales, hair powder and dust etc. produced when the rice moth cage 4 rotates enter the filter bag 98 with the air and are collected to ensure that the scales, hair powder and dust generated when the rice moth cage 4 rotates The powder will not spread out of the automatic rice moth egg removal device 100 to pollute the operating environment.

In this embodiment, the ventilation mechanism 9 further includes a collecting pipe 99 . One end of the collection pipe 99 is installed on the connection pipe 94 and communicates with the connection pipe 94, and the other end of the collection pipe 99 is detachably installed at the rice moth inlet and outlet 446 places. After rice moth ovum collection is finished, one end of collection pipe 99 can be installed in the rice moth import and export 446 places, open fan 97, make in the collection box 96 be negative pressure by fan 97, thereby the rice in the rice moth cage 4 The moth is sucked into the filter bag 98 through the collection pipe 99 to collect the rice moth quickly. It can be understood that, in other embodiments, one end of the collecting pipe 99 can also be installed on the casing 92 .

The automatic rice moth egg extraction device 100 also includes a baffle plate 10 and a driving assembly (not shown). The baffle 10 is installed in the connecting tube 94 , and the driving assembly can drive the baffle 10 to rotate between a first position and a second position. When the baffle plate 10 rotates to the first position, the baffle plate 10 seals the communication hole 942 and makes the collection pipe 99 communicate with the filter bag 98, so as to prevent rice moth from entering the housing 2 from the communication hole 942; the baffle plate 10 rotates to the In the second position, the communication hole 942 is opened so that the housing 2 communicates with the filter bag 98, and the communication channel between the collection pipe 99 and the filter bag 98 is closed.

In this embodiment, the casing 2, the shell 92, the collection pipe 99 and the collection box 96 can all be made of transparent materials, so as to facilitate the observation of the collection of rice moth eggs and rice moths.

When using the device 100 for automatically getting rice moth eggs, at first, open the hole cover 5, place the rice moth in the rice moth cage 4, then cover the hole cover 5 on the rice moth inlet and outlet 446, to prevent the rice moth from flying out of the rice moth cage 4. Secondly, turn the baffle plate 10 to the second position to open the communication hole 942 . After rice moth lays eggs, start fan 97 and drive mechanism 6, at this moment, rice moth cage 4 rotates relative to housing 2, and hairbrush 7 sweeps on the peripheral wall 425 of rice moth cage 4 to be attached to rice moth cage 4 The rice moth ovum on the sweep falls in the ovum collection drawer 8. In this process, the blower fan 97 of operation makes in the collection box 96 be negative pressure, thereby the scale that rice moth cage 4 is rotated, hair powder and dust etc. enter in the filter bag 98 with air. At last, after the rice moth ovum is collected, the ovum collection drawer 8 is drawn out, and the rice moth ovum can be taken out. Then open the hole cover 5, install one end of the collection pipe 99 on the first shaft portion 442, turn the baffle plate 10 to the first position, close the communication hole 942 and make the collection pipe 99 communicate with the filter bag 98. Make in the collection box 96 by fan 97 negative pressure, thereby the rice moth in the rice moth cage 4 is sucked in the filter bag 98 through collection pipe 99, to collect the rice moth after laying eggs fast.

It can be understood that the structure of the cage body 42 is not limited to this embodiment. In other embodiments, the cage body 42 may also be in the shape of a sphere, and the rotating shaft 44 is connected to the cage body 42 , and driven by the drive mechanism 6 , the cage body 42 is driven to rotate.
