description The utility model discloses a constant-speed sampling device for environmental particulate matters, and relates to the technical field of environmental protection. The device comprises an air temporary storage box and a second sealing cover, one end of the air temporary storage box is rotatably clamped with a first sealing cover, the top of the air temporary storage box is fixedly welded with an angle adjusting plate, the inner side of the air temporary storage box is provided with the second sealing cover, the top of the second sealing cover is rotatably clamped with a sliding plate, and one side of the second sealing cover is provided with a stepping motor. According to the environment particulate matter sampling device, the air temporary storage box and the second sealing cover are arranged, so that the problems that the environment particulate matter sampling device often needs to be used in sunny and windless weather, the sampling time is limited, the use flexibility is low, and the change of the outdoor
