Oxygenation device for mushroom planting greenhouse

The invention discloses an oxygenation device for a mushroom planting greenhouse. The oxygenation device comprises a base. A sliding groove is formed in the base; a moving seat is slidably connected into the sliding groove; a plurality of sets of pneumatic telescopic air cylinders are fixedly connected into the movable base, and a supporting frame is fixedly connected to the tops of the pneumatic telescopic air cylinders. The top of the support frame is fixedly connected with an oxygen generator; the two ends of the oxygen generator communicate with connecting pipes, and the outer sides of the connecting pipes are slidably connected with sleeves. The side, away from the connecting pipe, of the sleeve communicates with a gas collecting box. By arranging the base, the movable seat can slide on the base and is used for carrying out oxygen therapy on the parallel mushroom planting frames in the greenhouse, the oxygen generator is lifted through the pneumatic telescopic air cylinder, then oxygen therapy can be car
