The invention relates to a mobile spore trapper. The mobile spore trapper comprises a base plate, moving mechanisms, an adjusting mechanism, fixing frames and spore trapper bodies; a circular throughhole is formed in the middle of the base plate, the moving mechanisms are mounted at the lower end of the base plate, the adjusting mechanism is mounted at the upper end of the base plate, and the fixing frames are mounted on the side wall of the adjusting mechanism and internally provided with the spore trapper bodies; the adjusting mechanism comprises a mounting frame, an annular guide rail, anadjusting motor, an adjusting frame, an adjusting plate, sliding plates, a linear sliding rail, connecting plates, telescopic plates, a lifting branch chain, a work cylinder, a limiting air cylinder and a supporting frame. The mobile spore trapper can solve the problems that in the use process of an existing spore trapper, movement is inconvenient, the position adjustment flexibility is poor, onlyspores at one position can be trapped and mounted every time, and disassembly is complicated, and can achieve the function of moving and adjusting multiple spore trapper bodies simultaneously.
