The connecting block 51 and the pulley 53 are connected by a belt drive. By starting the motor 52, the output shaft of the motor 52 rotates to drive The pulley 53 rotates, and the rotation of the pulley 53 drives the connecting block 51 to rotate through the belt. The two first ventilation pipes 54 are connected to the left and right sides of the bottom of the connecting block 51, the exhaust pipe 55 is connected to the lower surface of the connecting block 51, and the two second ventilation pipes 56 are connected to the left and right sides of the exhaust pipe 55. One end of the exhaust pipe 57 is rotatably connected to the connecting block 51 through a sealed bearing. When the connecting block 51 rotates, it drives the two first ventilation pipes 54 to rotate, and drives the exhaust pipe 55 and the two second ventilation pipes 56 to rotate, thereby improving the exhaust efficiency of the greenhouse body 1.

The cross-sectional shape of the first ventilation pipe 54 is L-shaped, and the two first ventilation pipes 54 are symmetrically distributed at the left and right ends of the vertical central axis of the connecting block 51.

[0036] The working principle of the above embodiment is:

[0037] (1) The smoke generated by the coke oven body 2 can be introduced into the inner cavity of the smoke exhaust pipe through the smoke collection cover. The smoke entering the inner cavity of the smoke exhaust pipe can be guided into the dust removal ground station for purification through the smoke exhaust pipe; the noise generated by the fan 63 can be reduced by the sound insulation cover 62. By starting the fan 63, the air inlet end of the fan 63 draws in external air through the air inlet cylinder 64. When the external air enters the air inlet cylinder 64, it needs to pass through the filter screen, thereby effectively reducing the entry of dust. The filtered air enters the inner cavity of the fixed box 61, and then the air enters the ventilation pipe 6 through the guide of the air outlet pipe 65. 6, air can be sprayed out through multiple nozzles 67, and the sprayed air can enter the inner cavity of the greenhouse body 1 through the vent hole 684 and the air guide hole 685, and the electric push rod 682 is started, and the piston rod of the electric push rod 682 is extended, thereby pushing the movable plate 683 to move. The piston rod of the electric push rod 682 is extended and shortened, so that the air passing through the air guide hole 685 can be sprayed out at different positions. After passing through the coke oven body 2, the air can absorb the heat and smoke of the coke oven body 2, and then move toward the smoke collection hood, so that the air can circulate quickly, thereby improving the ventilation effect of the greenhouse.

[0038] (2) By starting the motor 52, the output shaft of the motor 52 rotates to drive the pulley 53 to rotate. The rotation of the pulley 53 drives the connecting block 51 to rotate through the belt. When the connecting block 51 rotates, it drives the two first ventilation pipes 54 to rotate, and drives the exhaust pipe 55 and the two second ventilation pipes 56 to rotate, thereby improving the exhaust efficiency of the greenhouse body 1. Finally, the exhaust gas enters the inner cavity of the exhaust pipe 57 through the connecting block 51, and then flows to the exhaust gas purification station for purification.
