The angle adjustment mechanism includes a bracket, a coil spring and a driving mechanism. The corresponding connecting plates of the first conical cylinder and the second conical cylinder are respectively connected and fixed by a bracket. One end of the coil spring is fixed to one of the brackets, and the other end passes through the spring grooves of the remaining brackets in sequence and then connected to the driving mechanism. The angle adjustment mechanism can adjust the opening of the conical cylinder to simultaneously shrink or expand, thereby realizing angle adjustment to adapt to materials to be dried with different particles.
