The right side of the outer surface of the ventilation shell 1 is fixedly connected to the mounting frame 2, and the left end of the ventilation shell 1 is fixedly connected to the air outlet shell 4. The air outlet shell 4 will guide air to the inside of the external granary for ventilation. A rubber seismic isolation plate 21 is bonded to the right end surface of the mounting frame 2. The rubber seismic isolation plate 21 will absorb most of the vibrations transmitted from the mounting frame 2 to avoid large resonance noise between the mounting frame 2 and the external granary wall. Both the mounting frame 2 and the rubber seismic isolation plate 21 are provided with mounting through holes. The mounting through holes facilitate the external expansion bolts to install and fix the mounting frame 2 at a specified position on the external granary wall. In this process, it is necessary to make the right half of the ventilation shell 1 inside the air inlet of the external granary, while the left half of the ventilation shell 1 is inside the external granary.

[0028] An insecticidal lamp 5 is installed on the lower end face of the air outlet shell 4. The insecticidal lamp 5 takes advantage of the phototaxis of insects and utilizes an insect-attracting light source in a specific spectral range to which insects are sensitive, so as to attract insects and effectively kill them, thereby reducing the impact of pests on food in the external granary. Since the internal detailed structure and working principle of the insecticidal lamp 5 are relatively mature technologies in the prior art, they will not be described in detail here. A ventilation component 3 for supplying air to the inside of the external granary is provided inside the ventilation shell 1, and a knocking component 6 is provided on the lower end face of the ventilation shell 1, and the knocking component 6 is used to knock the ventilation shell 1 to cause it to vibrate.

[0029] The ventilation assembly 3 includes an external protective net 31, a driving motor 32, a transmission shaft 33, ventilation fan blades 34 and an air filter screen 35. The external protective net 31 is installed on the right end face of the ventilation shell 1. The external protective net 31 will not only protect the entrance of the ventilation shell 1, but also filter a part of the dust in the passing air. The external protective net 31 is a detachable structure. The detachable external protective net 31 is convenient for cleaning or replacement at a later time. A driving motor 32 is installed inside the ventilation shell 1. The driving motor 32 is connected to an external control switch through a wire.

The left end of the transmission shaft 33 is installed with ventilation fan blades 34. The transmission shaft 33 will drive the ventilation fan blades 34 to rotate so that the rotating ventilation fan blades 34 can supply air to the air outlet shell 4.

[0030] An air filter panel 35 is inserted on the left side inside the ventilation shell 1. The air filter panel 35 is made of nylon filter. The air filter panel 35 made of nylon filter has low resistance, can be repeatedly cleaned, is highly economical, and has good impact resistance, so as to filter most of the dust in the passing air and prevent dust in the external air from directly entering the outside granary and causing pollution. A lifting handle 351 is provided on the upper end surface of the air filter panel 35. The lifting handle 351 is convenient for the staff to lift and disassemble the air filter panel 35 by hand. An insertion slot 37 is opened on the left side inside the ventilation shell 1. The insertion slot 37 matches the air filter panel 35. The insertion slot 37 facilitates the air filter panel 35 to be inserted into the ventilation shell 1 for use.

[0031] A guide cavity 38 is provided on the left side of the lower end face of the ventilation shell 1, and the guide cavity 38 is connected to the connecting shell 39. The guide cavity 38 will guide the dust impurities that are shaken off the right end face of the air filter screen 35 to the connecting shell 39. The left side of the lower end face of the ventilation shell 1 is fixedly connected with the connecting shell 39. The connecting shell 39 will not only guide the dust impurities in the guide cavity 38 to the ash collecting box 36, but also support the ash collecting box 36. The outer surface of the connecting shell 39 is provided with an ash collecting box 36. The ash collecting box 36 is provided on the outer surface of the connecting shell 39. 6 will collect the dust or impurities that are shaken off so that the staff can clean them up in a centralized manner later. A fixing screw 361 is installed on the upper side of the interior of the ash box 36. The fixing screw 361 is a butterfly screw. The fixing screw 361 is a butterfly screw, which is convenient for the staff to disassemble and assemble it by hand. A gripping handle 362 is provided on the left end surface of the ash box 36. The gripping handle 362 is convenient for the staff to take the ash box 36 by hand, thereby making it convenient for the staff to disassemble and assemble the ash box 36 by hand.

[0032] Embodiment 2:

[0033] On the basis of Example 1, in this embodiment, the transmission shaft 33 drives the small reducer 65 to work through the active pulley 61, the transmission belt 62, the driven pulley 63 and the connecting shaft 64 in sequence. At this time, the small reducer 65 will decelerate the high speed transmitted by the connecting shaft 64 and drive the driven shaft 66 to rotate at a low speed, so that the driven shaft 66 drives the knocking ball 68 to rotate at a low speed through the follower spring 67 to knock the ventilation shell 1, so that the ventilation shell 1 drives the air filter plate 35 and the external protective net 31 to vibrate and shake off a part of the dust or impurities blocked by the right end surface of the air filter plate 35 and the external protective net 31, thereby extending the cleaning cycle of the air filter plate 35 and the external protective net 31, and there is no need for staff to regularly disassemble and clean the air filter plate 35 and the external protective net 31.

[0034] The knocking assembly 6 includes a driving pulley 61, a transmission belt 62, a driven pulley 63, a connecting shaft 64, a small reducer 65, a driven shaft 66, a follower spring 67 and a knocking ball 68. A driving pulley 61 is arranged on the annular side of the transmission shaft 33. The driving pulley 61 is connected to the transmission shaft 33 by welding. The driving pulley 61 drives the driven pulley 63 to rotate through the transmission belt 62. A small reducer 65 is installed on the left side of the lower end surface of the ventilation shell 1. The small reducer 65 reduces the high speed transmitted from the connecting shaft 64 and drives the driven shaft 66 to rotate at a low speed. Since the internal detailed structure and working principle of the small reducer 65 are relatively mature technologies in the prior art, they will not be elaborated on here.

[0035] The right end of the small reducer 65 is connected to a connecting shaft 64, which drives the small reducer 65 to work. The right end of the connecting shaft 64 is provided with a driven pulley 63, which is connected to the connecting shaft 64 by welding. The driven pulley 63 drives the connecting shaft 64 to rotate. A transmission belt 62 is provided between the driven pulley 63 and the driving pulley 61. The left end of the small reducer 65 is connected to a driven shaft 66, which drives the follower spring 67 to rotate. A follower spring 67 is provided on the upper side of the annular side of the driven shaft 66. The follower spring 67 is connected to the knocking ball 68 and the driven shaft 66. They are all connected by welding. The follower spring 67 not only drives the knocking ball 68 to rotate, but also enables the knocking ball 68 to have a certain degree of elasticity when it rotates to knock on the ventilation shell 1. The upper end of the follower spring 67 is connected to the knocking ball 68. The knocking ball 68 knocks on the ventilation shell 1 when rotating, so that the ventilation shell 1 drives the air filter plate 35 and the external protective net 31 to vibrate, thereby shaking off a part of the dust or impurities blocked by the right end surface of the air filter plate 35 and the external protective net 31, thereby extending the cleaning cycle of the air filter plate 35 and the external protective net 31.

[0036] Working principle: when it is necessary to ventilate the external granary, the staff only needs to start the driving motor 32, so that the driving motor 32 can drive the transmission shaft 33 to rotate, and the transmission shaft 33 will drive the ventilation fan blades 34 to rotate, and the rotating ventilation fan blades 34 will generate negative pressure inside the ventilation shell 1 and suck the external air on the right side, and the air sucked into the ventilation shell 1 will be transported to the left and enter the external granary through the air outlet shell 4 for ventilation. In this process, the external protective net 31 will block most of the large particles of impurities or dust in the passing air, and the air filter plate 35 will block most of the small particles of impurities or dust in the passing air, thereby preventing dust or impurities in the air from directly entering the external granary and causing pollution; at the same time, the transmission shaft 33 will drive the active pulley 61 to rotate together, so that the active pulley 61 drives the driven pulley 63 to rotate through the transmission belt 62, and the driven pulley 63 will drive the small reducer 65 to work through the connecting shaft 64. At this time, the small reducer 6 5 will decelerate the high speed transmitted by the connecting shaft 64 and drive the driven shaft 66 to rotate at a low speed, and then the driven shaft 66 drives the knocking ball 68 to rotate at a low speed through the following spring 67; in this process, the knocking ball 68 will knock the ventilation shell 1 when rotating upward, so that the ventilation shell 1 drives the air filter plate 35 and the external protection net 31 to vibrate, so as to shake off part of the dust or impurities blocked by the right end surface of the air filter plate 35 and the external protection net 31, thereby extending the air filter plate The cleaning cycle of 35 and the external protective net 31 is arranged, and the dust or impurities shaken off from the right end face of the air filter plate 35 will fall into the dust collecting box 36 through the guide cavity 38 and the connecting shell 39, while the dust and impurities shaken off from the right end face of the external protective net 31 will directly fall downward to the external ground. Later, the staff only needs to loosen and disassemble the fixing screws 361 by hand, and then the dust collecting box 36 can be moved down and disassembled, so that the staff can pour out and clean the dust inside the dust collecting box 36.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
