Description

Technical Field

[0001] The utility model relates to the technical field of grain silo ventilation, in particular to an adjustable grain silo ventilation duct structure. Background Art

[0002] When grain is stored in a granary, the accumulation of grain makes it difficult for the internal heat to dissipate, especially in summer, which can easily cause biological reactions in the surrounding grains and continue to generate heat, causing the grains to germinate and be damaged, or even become moldy and damaged. Some existing granaries lay ground cages on the ground and bury them with grains, and continuously extract the heat of the grains from the bottom to keep the grains fresh. However, some existing ground cages are composed of arc-shaped mesh plates spliced ​​together. First of all, the area in contact with the grains is small, and the heat absorption effect on the grains is poor. In addition, the amount of exhaust air can be adjusted only by the speed of the fan, which is also relatively limited. It is not easy to achieve precise control of the heat dissipation of the grains, and it is not convenient to use. Utility Model Content

Multiple steel rods 152 are equidistantly connected to the outer wall of the card seat 151. One end of the steel rod 152 is connected to the adjacent baffle 140. The rotating card seat 151 can drive the multiple steel rods 152 to move, thereby pulling the baffle 140 to rotate through the multiple steel rods 152. At the same time, the multiple baffles 140 are rotated and regulated to change the ventilation space leaked from the ventilation slot 131. The interior of the card seat 151 is fixedly sleeved with a shaft rod 153. The rear end of the shaft rod 153 is fixedly connected with a clamping block 154. The clamping block 154 can be movably connected with the front end of the adjacent shaft rod 153. The shaft rod 153 can be used to rotate and regulate the card seat 151. When multiple ventilation mechanisms 100 are docked, multiple shaft rods 153 can be connected head to tail. All shaft rods 153 can be rotated by rotating the shaft rod 153 at the outermost end.

After the rotating disk 330 rotates, the spring 341 drives the slide plate 340 to move, so that the clamping rod 342 is clamped into the adjacent spring 341 to fix the rotating disk 330, thereby limiting the position of the clamping seat 151.

[0027] Two mounting grooves 240 are provided inside the support frame 200, and a plug rod 210 is slidably connected between the two inner walls of the mounting groove 240. Both ends of the plug rod 210 penetrate the support frame 200. A limiting module 230 for limiting the plug rod 210 is provided inside the mounting groove 240. When multiple ventilation mechanisms 100 are assembled end to end, the vertical plate 212 can be moved from the bottom of the support frame 200 to move the plug rod 210, so that the front end of the plug rod 210 leaks out and is stuck into the rear side of the adjacent support frame 200 for docking, ensuring that multiple filter cartridges 120 can be stably Aligned, a moving seat 220 is slidably connected between the two inner walls of the mounting groove 240, the bottom of the moving seat 220 passes through the support frame 200, and the bottom of the moving seat 220 is rotatably connected with a ball 221.

When the front end of the insertion rod 210 leaks out, the moving seat 220 does not contact the guide block 211. The moving seat 220 is limited by the spring 222. After the rod 210 is moved back into the support frame 200, the rod 210 drives the two guide blocks 211 to contact the moving seat 220, driving the moving seat 220 to move downward to the outside of the support frame 200, and the bottom ball 221 of the moving seat 220 contacts the bottom surface for carrying and transporting the support frame 200. The limit module 230 includes a vertical plate 212 fixedly connected to the bottom of the rod 210, the vertical plate 212 passes through the support frame 200 and is slidably connected thereto, and two limit plates 231 are fixedly connected to the inner bottom wall of the mounting groove 240.

The rear end of the pull rod 232 passes through the support frame 200 and extends to the outside. A spring 234 is fixedly connected between the rear side of the limit block 233 and the limit plate 231. Through the engagement of the limit block 233 with the vertical plate 212, the two states of leakage and storage of the insertion rod 210 can be limited.

The support frame 200 supports the filter cartridge 120, so that the grain can be buried to the bottom of the filter cartridge 120, which greatly increases the contact area with the grain, facilitates the precise control of the heat dissipation of the grain, and is convenient to use.

[0029] When installing multiple ventilation mechanisms 100, in the initial state, the insertion rod 210 is inside the support frame 200, and the movable seat 220 leaks out from the bottom of the support frame 200 under the resistance of the guide block 211. The support frame 200 and the ventilation mechanism 100 thereon can be pushed by using the ball 221 at the bottom of the movable seat 220 to contact the ground. After the ventilation mechanism 100 is pushed to the vicinity of the designated installation position, the pull rod 232 can be pulled to separate the limit block 233 from the vertical plate 212, and the support frame 200 can be tilted as a whole to move from the support frame 200 to the support frame 200. The bottom of the support frame 200 moves the vertical plate 212, so that the insertion rod 210 leaks out from the front side of the support frame 200. At this time, the guide block 211 is away from the moving seat 220. The moving seat 220 is stored inside the support frame 200 under the drive of the spring 1 222. Multiple support frames 200 can be assembled end to end so that the front end of the insertion rod 210 is inserted into the rear side of the adjacent support frame 200. When splicing, the shaft rod 153 needs to be clamped end to end. The support frame 200 equipped with the fixing mechanism 300 is set at the rear end of a row of ventilation mechanisms 100;

[0030] When the baffle 140 needs to be rotated, pull the slide plate 340 to pull the clamping rod 342 out from the inside of the turntable 330, and then rotate the turntable 330 to drive the shaft rod 153 to rotate, thereby driving multiple shaft rods 153 and the clamping seat 151 to rotate. The clamping seat 151 pulls multiple baffles 140 to rotate through the steel rod 152, so that the blocking area of ​​the ventilation slot 131 changes, thereby changing the amount of ventilation.
