[0031] like Figure 1 As shown, it is a grain silo anti-insect ventilation mechanism 100 shown in the utility model, which is installed on the grain silo to ventilate the grain silo.

[0032] like Figure 1As shown, the granary insect-proof ventilation mechanism 100 includes: a ventilation pipe 10, a canopy 20 and an insect-proof component 30, wherein the ventilation pipe 10 is installed on the granary and communicated with the granary, the canopy 20 is installed on the ventilation pipe 10 to prevent rainwater from entering the granary through the ventilation pipe 10, and the insect-proof component 30 has an insect-proof net 34, and is used to be locked with the ventilation pipe 10. The insect-proof component 30 is locked or released through the ventilation pipe 10 to achieve the fixation or disassembly of the ventilation pipe 10 and the insect-proof component 30, thereby reducing the disassembly time of the insect-proof component 30 and achieving the purpose of improving the replacement and cleaning efficiency of the insect-proof net 34.

[0033] Below, combined Figures 1 to 5 , the above-mentioned grain silo anti-insect ventilation mechanism 100 is further explained.

[0034] like Figures 1 to 4 As shown, the ventilation pipe 10 includes a pipe body 11 and a rotary lock 12. The pipe body 11 is installed on the granary and is provided with a vent 111 connected to the granary. The number of the rotary locks 12 is multiple, and each rotary lock 12 is installed on the pipe body 11. The pipe body 11 includes a pipe body 112 and a boss 113. The boss 113 is provided with a vent 111 and a mounting groove 114 connected to the vent 111. The rotary lock 12 is installed in the mounting groove 114. The insect-proof component 30 is arranged in cooperation with the mounting groove 114 to prevent the insect from entering the granary through the mounting groove 114. The component 30 is positioned, and there are two rotary locks 12, which are respectively arranged on both sides of the vent 111. Each rotary lock 12 includes a rotary rod 121 and a locking plate 122. The rotary rod 121 is rotatably connected to the boss 113 of the tube body 11, and the locking plate 122 is connected to the rotary rod 121. In order to facilitate the control of the rotation of the locking plate 122, the locking plate 122 is provided with an avoidance hole 123 for the hand to pass through, so that the locking plate 122 can be held by passing through the avoidance hole 123, thereby achieving the purpose of improving the convenience of controlling the rotation of the locking plate 122.

[0035] like Figure 1 As shown, the canopy 20 is connected to the pipe body 11 and forms a ventilation area 21 connected to the ventilation hole 111 with the pipe body 11. The air flow can interact in the ventilation area 21 to enter the granary through the ventilation hole 111 connected to the ventilation area 21 or the air in the granary can be discharged into the ventilation area 21 through the ventilation hole 111.

[0036] like Figure 5As shown, the insect-proof component 30 includes a frame 31, a rubber pad 32, a handle 33, an insect-proof net 34 and a protective net 35. The frame 31 covers the vent 111 and is buckled with the rotary lock 12, wherein the frame 31 includes a baffle 311, a surrounding wall 312 and a clamping strip 313. The baffle 311 is arranged in cooperation with the mounting groove 114 to be positioned through the mounting groove 114. The baffle 311 is provided with a through hole 314 for the rotary lock 12 to pass through, and is used to be buckled with the rotary lock 12 so that the rotary lock 12 can lock the baffle 311 in the mounting groove 114. The rubber pad 32 is arranged between the baffle 311 and the boss 113 of the tube body 11 to enhance the sealing effect of the baffle 311 and the boss 113. The surrounding wall 312 is inserted into the vent 111, and the clamping strip 313 is inserted into the vent 111. There are multiple 313s, and each adjacent card strip 313 forms a first card slot 315 and a second card slot 316 that are spaced apart. The first card slot 315 is located on the side close to the ventilation area 21. The protective net 35 is installed in the first card slot 315 to prevent debris from directly contacting the insect-proof net 34, thereby increasing the service life of the insect-proof net 34. The insect-proof net 34 is installed in the second card slot 316 and closes the vent 111 to prevent insects from entering the granary. The handle 33 is connected to the side of the baffle 311 of the frame 31 away from the vent 111. There are two handles 33, which are respectively arranged on both sides of the vent 111 of the frame 31 and are staggered with each rotary lock 12 to avoid interfering with the use of the rotary lock 12.

[0037] Specifically, the locking piece 122 has a first use position and a second use position. Figure 2 As shown, when the locking piece 122 is in the first use position, the position of the locking piece 122 is set corresponding to the shape of the through hole 314, so that the locking piece 122 passes through the through hole 314. Figure 3 As shown, when the locking piece 122 is in the second use position, the locking piece 122 is rotated to change its position so that the locking piece 122 and the through hole 314 are staggered and abut against the blocking piece 311 to fix the blocking piece 311 in the mounting groove 114 of the boss 113.

[0038] The insect-proof ventilation mechanism 100 of the granary shown in the present invention is used as follows: when the insect-proof net 34 needs to be installed on the ventilation pipe 10, the frame 31 on which the insect-proof net 34 is installed is controlled by the handle 33 to cover the ventilation opening 111 of the tube body 11 of the ventilation pipe 10, so that the insect-proof net 34 closes the ventilation opening 111, and the rotary lock 12 is controlled to lock the frame 31 on the tube body 11 to achieve the installation and fixation of the insect-proof net 34. When the insect-proof net 34 needs to be removed, the rotary lock 12 is controlled to open, and the frame 31 is controlled by the handle 33 to separate from the tube body 11 of the ventilation pipe 10, so that the insect-proof net 34 can be taken away from the ventilation pipe 10, and the insect-proof net 34 can be removed. In addition, the handle 33 is used to facilitate the control of the frame 31 on which the insect-proof net 34 is installed to move to a predetermined position to clean the insect-proof net 34, thereby facilitating the cleaning of the insect-proof net 34 and achieving the purpose of improving the cleaning efficiency of the insect-proof net 34.

[0039] The beneficial effects of the grain silo insect-proof ventilation mechanism 100 shown in the utility model are: the frame 31 on which the insect-proof net 34 is installed is fixed to the pipe body 11 by using the rotary lock 12. By opening the rotary lock 12 and lifting the frame 31 with the handle 33, the insect-proof net 34 can be separated from the pipe body 11 of the ventilation pipe 10. Compared with the method of removing screws, the time and convenience of removing the insect-proof net 34 can be effectively reduced, thereby reducing the disassembly time of the insect-proof net 34 and achieving the purpose of improving the replacement and cleaning efficiency of the insect-proof net 34.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
