When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] like Figures 1 to 3 As shown, the utility model provides an insect-proof device for planting broccoli, comprising a mounting tube 1, which is a cylinder, and the mounting tube 1 is fixedly embedded on the side wall of the greenhouse, and a mounting plate 2 is fixedly installed on one side of the mounting tube 1 through multiple mounting rods, and the mounting rods are radial, and a driving motor 3 is fixedly embedded on the mounting plate 2, and the driving motor 3 can be switched between forward and reverse rotations, and a fan blade 4 is fixedly installed on the end of the output shaft of the driving motor 3, and the fan blade 4 is located in the mounting tube 1, and an insect-killing net 6 is fixedly installed in the mounting tube 1 through a mounting ring 5, and positive electrodes and negative electrodes are embedded on the upper and lower sides of the mounting ring 5, and the positive electrode and the negative electrode are electrically connected to the insect-killing net 6, and the positive electrode and the negative electrode are electrically connected to a power supply, and a cover plate 7 is hinged on the outside of the mounting tube 1, and the cover plate 7 is located on the side of the outside of the mounting tube 1 away from the driving motor 3, and a handle is fixedly installed on the outside of the cover plate 7.

[0025] When ventilation is needed in the greenhouse, the cover plate 7 can be opened, and the driving motor 3 drives the fan blades 3 to rotate to generate wind force, thereby driving rapid ventilation in the greenhouse. When pests enter the installation tube 1, they contact the insect killing net 6 and are killed by the low-voltage current on the insect killing net 6. At the same time, the wind generated by the fan blades 3 can blow the dead bodies of the pests off the insect killing net 6, thereby preventing the pests from adhering to the insect killing net 6 and affecting the subsequent insect killing effect.

[0026] In this embodiment, a protective net 8 is movably installed in the installation tube 1, and first threaded holes are opened on the left and right sides of the installation tube 1. Connecting plates 9 are vertically fixedly installed on both sides of the protective net 8. A first through hole is opened on the connecting plate 9. A first bolt is movably installed in the first through hole. The first bolt is threadedly connected to the first threaded hole for easy disassembly and assembly.

[0027] The protective net 8 can protect the insect-killing net 6. When the driving motor 3 is reversed, the wind direction in the installation tube 1 is inward, and the protective net 8 can prevent large pests or debris such as leaves from contacting the insect-killing net 6. When a certain amount of pests are killed in the installation tube 1, the dead bodies of the pests are accumulated at the bottom of the installation tube 1. At this time, the first bolt can be removed, the protective net 8 can be taken out, and the dead bodies of the pests can be cleaned.

[0028] In this embodiment, the diameter of the cover plate 7 is smaller than the inner diameter of the mounting tube 1, and a sealing rubber pad is circumferentially mounted on the cover plate 7 to improve the sealing effect and prevent pests from entering the mounting tube 1, thereby playing an insect-proof role when the insect-killing net 6 is not working.

[0029] In this embodiment, a mounting plate is fixedly installed on the outside of the mounting tube 1, and a second threaded hole is opened on the mounting plate. A connecting plate 10 is fixedly installed on the side end of the cover plate 7, and a second through hole is opened on the connecting plate 10. A second bolt is movably installed in the second through hole, and the second bolt is threadedly connected to the second threaded hole to improve the stability of the cover plate 7.

[0030] When in use, two or more devices are embedded on the side wall of the broccoli planting greenhouse according to the scale of the broccoli planting greenhouse.

[0031] When the driving motor 3 of the device on one side rotates forward, the driving motor 3 of the device on the other side rotates reversely, thereby improving the ventilation efficiency. After running for a period of time, the driving motor 3 rotating forward is switched to reverse rotation, and the driving motor 3 rotating reversely is switched to forward rotation.

[0032] When the driving motor 3 rotates forward, the wind direction in the installation tube 1 is outward; when the driving motor 3 rotates reversely, the wind direction in the installation tube 1 is inward. When the driving motor 3 switches from reverse rotation to forward rotation, the debris on the protective net 8 is blown off.

[0033] When ventilation is required in the broccoli planting greenhouse, the second bolt is removed and the cover plate 7 is opened by the handle.

[0034] The drive motor 3 and the insect-killing net 6 are started, and the drive motor 3 drives the fan blades 3 to rotate to generate wind force, which drives rapid ventilation in the greenhouse. When pests enter the installation tube 1, they contact the insect-killing net 6 and are killed by the low-voltage current on the insect-killing net 6. At the same time, the wind generated by the fan blades 3 can blow the dead bodies of the pests off the insect-killing net 6, preventing the pests from adhering to the insect-killing net 6 and affecting the subsequent insect-killing effect.

[0035] When a certain amount of pests are killed in the installation tube 1, the dead bodies of the pests are accumulated at the bottom of the installation tube 1. At this time, the first bolt can be removed, the protective net 8 can be taken out, and the dead bodies of the pests can be cleaned.

[0036] After the ventilation is completed, the driving motor 3 and the insect-killing net 6 are turned off, the cover plate 7 is put back on, and the cover plate 7 is fixed to the mounting tube 1 by the second bolt.

[0037] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any way. Any simple modification, change and equivalent change made to the above embodiment according to the essence of the utility model technology still falls within the protection scope of the technical solution of the utility model.
