[0019] Figure 1 The utility model schematically shows a ventilation duct for a grain depot that is easy to install, including a pipe body 1, a plurality of air outlets 12 are provided on the surface of the pipe body 1, and a guide plate 13 is installed in the air outlet 12. The air outlet 12 can facilitate the fresh gas in the pipe body 1 to flow out of the pipe body 1, and the guide plate 13 can effectively guide the fresh gas to flow out. A clamping block 2 is fixedly installed at one end of the pipe body 1, and a clamping groove 21 is provided at the other end. The clamping block 2 and the clamping groove 21 are fixedly connected by interference fit, so that multiple pipe bodies 1 can be conveniently connected in series through the clamping block 2 and the clamping groove 21. A mounting block 3 integrally formed with the pipe body 1 is provided on one radial side of the pipe body 1. The mounting block 3 is a hollow structure. The mounting block 3 A connecting device is provided inside, and the connecting device is fixedly connected to a fixing device 5.

A hook 7 is fixedly installed on one radial side of the pipe body 1, and a tool such as a draft cloth that is easily blown by the wind can be hung in the hook 7, so as to facilitate observation of whether the air outlet 12 is blowing air. Sealing strips are fixedly installed on both ends of the pipe body 1, and the sealing strips are made of a material with good sealing properties such as rubber. They are fixedly connected to the two ends of the pipe body by gluing, which can effectively prevent air leakage at both ends of the pipe body 1 and avoid affecting the gas flow in the pipe body 1.

[0020] like Figure 2 Figure 3The connecting device shown includes a through hole 4, and a fixing groove 41 is formed on both sides of the through hole 4. A fixing block 42 is placed in the fixing groove 41. One end of the fixing block 42 is fixedly connected to one end of a connecting column 43, and the other end of the connecting column 43 is fixedly connected to a protective block 44. The size of the protective block 44 is larger than the connecting column 43. During installation, the protective block 44 contacts the surface of the mounting block 3, which can provide a supporting force for the clamp 51 and reduce the pressure of the connecting column 43. The other end of the fixing block 42 is in contact with a reinforcing block 45. The side of the reinforcing block 45 away from the fixing block 42 is fixedly connected to one end of a spring 46.
