Drying box for mineral sample detection

The utility model relates to the technical field of drying boxes, and discloses a drying box for mineral sample detection, which comprises a box body, the outer wall of the box body is rotatably connected with a box cover, an observation plate is embedded in the inner cavity of the box cover, a controller is fixedly assembled on the outer wall of the box cover, and a fan is arranged on the outer wall of the box body. According to different heights of mineral samples, the lower cross beam can be pulled according to the heights of the mineral samples, so that the rotating handle, the connecting handle and the straight handle drive the lower transverse plate to ascend and descend, the distance between the two transverse plates can be matched with the mineral samples, the mineral samples can be perfectly placed at the top of the lower transverse plate, and the controller transmits a signal; the drying machine receives the signal and operates, a mineral sample at the top of the transverse plate can be dried, and t
