The invention discloses an automatic atmospheric settlement sample collection device capable of freely controlling the height, which comprises a collection box.Acollection pipe is inserted into the collection box, a handle of the collection box is connected with a balloon through a string, the bottom of the collection box is fixedly connected with one end of a vertical line with scales, and the other end of the vertical line is wound on a winding reel; the collectionpipe comprises a pipe cover and a pipe body in threaded connection with the pipe cover. According to the device provided by the invention, the balloon drives the collectionbox to lift off; the height of the collectionbox is judged according to the scale accurate to centimeter on the vertical line; when the set height is reached, the remote controller is pressed down, the first electromagnet is controlled to be powered off, the second electromagnet is controlled to be powered on, the light rubber plug falls under the actionof magnetic force and gra
