The filtered air enters the greenhouse through the greenhouse planting ventilation holes on the drum to achieve ventilation of the greenhouse.

[0015] S2. During the ventilation process of the greenhouse, impurities and insects gradually clog the filter structure. When ventilation is performed, the drive motor is started, thereby driving all the drums to rotate through the linkage of the bevel gears. There are fixed plates and cleaning plates inside the rectangular frame. The cleaning plates are in contact with the inner wall of the insect-proof filter screen. During rotation, insects and impurities will be cleaned and dropped to ensure the filtering effect.

[0016] S3.

[0017] S4. Shielding cloth is set on the insect-proof filter plate and the drum to prevent insects and impurities from entering directly through the gaps. Insects and impurities will fall out when the connecting holes on the drum are connected and overlap with the air inlet slots on the greenhouse ventilation mounting plate. An insect attractant lamp is also set on the back of the greenhouse ventilation mounting plate to attract flying insects and further prevent them from entering the greenhouse.

[0018] The present invention provides an all-weather insect protection device and protection method for greenhouse planting through improvement, which has the following improvements and advantages compared with the prior art:

[0019] First, the present invention is provided with a greenhouse ventilation mounting plate, a rotating drum, an insect-proof filter screen plate, a cleaning plate, a fixing plate, a rectangular frame and ventilation holes for greenhouse planting. When the insect-proof filter screen plate rotates, the clogged dust and impurities are scraped off by the cleaning plate. When the insect-proof filter screen plate is separated from the cleaning plate, the dust and insect corpses that temporarily stay on the cleaning plate will fall out through the notch of the arc plate when they coincide with the connecting hole and the air inlet slot, thereby completing the self-cleaning of the filter structure. The rotating drum is in a rotating state, and the greenhouse planting ventilation holes on the rotating drum are also distributed in an arc-shaped array, so that the ventilation in the greenhouse is more uniform. When the rotating drum rotates together through the linkage structure, the flow direction of air entering during ventilation can be controlled, and the ventilation effect is more uniform. When the rotating drum rotates, it can cooperate with the fixed cleaning plate to realize the self-cleaning of the filter structure. The insect-proof filter screen plate is connected by a spring, and can also vibrate in cooperation with the spherical protrusion, thereby further enhancing the cleaning effect and improving the use efficiency of the greenhouse planting anti-collision protection device.

[0020] Secondly: the present invention is provided with an insect-proof filter screen, a spring and a shielding cloth. The vibration of the insect-proof filter screen further improves the cleaning effect. The insect-proof filter screen and the rotating drum are connected by the shielding cloth, which is convenient for shielding the gap between the rotating drum and the insect-proof filter screen, effectively preventing insects and dust from entering. The insect-proof filter screen is connected by the shielding cloth to ensure that the vibration is within a certain range, thereby improving the stability of the overall structure and ensuring the safety of the ventilation and filtration structure.

[0021] Thirdly, the present invention is provided with an air inlet slot, an inclined slot and an insect attractant lamp. An inclined slot is provided at the bottom of the air inlet slot, which is adapted to the position of the connecting hole and the cleaning plate to facilitate the output of fallen insects and dust and prevent the air inlet slot from being blocked.

[0037] An all-weather insect protection method for greenhouse planting, based on an all-weather insect protection device for greenhouse planting, comprises the following steps:

[0038] S1. During greenhouse planting, the greenhouse ventilation mounting plate 1 of the ventilation structure is installed at the ventilation position of the greenhouse. The air enters the rotating drum 9 of the rectangular frame 8 through the air inlet slot 12 of the greenhouse ventilation mounting plate 1, and then enters the insect-proof filter mesh plate 15 through the connecting hole 19 and the gap of the insect-proof filter mesh plate 15. Insects and impurities are filtered and remain inside the insect-proof filter mesh plate 15. The filtered air enters the greenhouse through the greenhouse planting ventilation holes 10 on the rotating drum 9 to realize ventilation of the greenhouse.

[0039] S2. During the ventilation process of the greenhouse, impurities and insects gradually clog the filter structure. During ventilation, the drive motor 6 is started, thereby driving all the rotating drums 9 to rotate through the linkage of the bevel gears. There are fixed plates 21 and cleaning plates 14 inside the rectangular frame 8. The cleaning plate 14 is in contact with the inner wall of the insect-proof filter plate 15. During rotation, insects and impurities will be cleaned and dropped to ensure the filtering effect.

[0040] S3. When the fixed cleaning plate 14 cleans the insects and impurities on the insect-proof filter screen 15, the cleaning plate 14 will also be pressed by the spherical protrusion 20, and the insect-proof filter screen 15 will be reset by the spring 16. The insect-proof filter screen 15 will continue to shake, thereby further improving the cleaning effect and ensuring that the filter structure continuously and efficiently filters the incoming air.

[0041] S4. A shielding cloth 18 is set on the insect-proof filter plate 15 and the rotating drum 9 to prevent insects and impurities from entering directly through the gaps. Insects and impurities will fall out when the connecting hole 19 on the rotating drum 9 is connected and overlapped with the air inlet slot 12 on the greenhouse ventilation mounting plate 1. An insect attractant lamp 17 is also set on the back of the greenhouse ventilation mounting plate 1 to attract flying insects to further prevent insects from entering the greenhouse.

[0042] Working principle: When using the greenhouse planting insect protection device, the greenhouse ventilation mounting plate 1 of the ventilation structure is installed at the greenhouse ventilation position, and the connecting hole 19 of the rotating drum 9 is aligned with the air inlet slot 12 on the greenhouse ventilation mounting plate 1. The outside air enters the inside of the rotating drum 9 through the air inlet slot 12 and the connecting hole 19, and then enters the inside of the greenhouse through the greenhouse planting ventilation hole 10 on the rotating drum 9 for ventilation. The dust and insects in the air are filtered by the insect-proof filter plate 15. When the filter structure needs to be cleaned, start the driving motor 6, so that the rotating rod 3 drives the bevel gear 1 4 to rotate, and then drives the support rod 22 to rotate through the meshing bevel gear 2 5. The drum 9 is made to rotate in the rectangular frame 8, and the insect-proof filter screen plate 15 also rotates accordingly. The other side of the rectangular frame 8 is also fixedly connected to a fixing plate 21 and a cleaning plate 14. When the insect-proof filter screen plate 15 rotates, the blocked dust and impurities are scraped off by the cleaning plate 14. When the insect-proof filter screen plate 15 is separated from the cleaning plate 14, the dust and insect corpses that briefly stay on the cleaning plate 14 will fall and be output through the notch of the insect-proof filter screen plate 15 when they coincide with the connecting hole 19 and the air inlet slot 12, completing the self-cleaning of the filtering structure. The drum 9 is in a rotating state, and the greenhouse planting ventilation holes 10 on the drum 9 are also distributed in an arc-shaped array, so that the ventilation in the greenhouse is more uniform.

[0043] A spherical protrusion 20 is provided on the insect-proof filter screen plate 15, and the insect-proof filter screen plate 15 is connected to the rotating drum 9 through a spring 16, so that when the insect-proof filter screen plate 15 is connected to the cleaning plate 14, it is continuously compressed and reset by the action of the spherical protrusion 20. The vibration of the insect-proof filter screen plate 15 further improves the cleaning effect. The insect-proof filter screen plate 15 and the rotating drum 9 are connected by a shielding cloth 18, which is convenient for shielding the gap between the rotating drum 9 and the insect-proof filter screen plate 15 to prevent insects and dust from entering.

[0044] An inclined groove 23 is provided at the bottom of the air inlet groove 12, which is adapted to the position of the connecting hole 19 and the cleaning plate 14 to facilitate the output of fallen insects and dust and prevent the air inlet groove 12 from being blocked. A lamp holder 11 and an insect attractant lamp 17 are also provided on the back of the greenhouse ventilation mounting plate 1, which can attract insects outside the greenhouse and reduce the filtering pressure of the insect-proof filter mesh plate 15.
