in the using process, the sliding rod (903) is further sleeved with an elastic piece A (904) for elastically resetting the cleaning head (905), and the cleaning head mounting seat (902), the sliding rod (903), the elastic piece A (904) and the cleaning head (905) jointly form an elastic cleaning type structure of the conveyor belt (3), so that the cleaning head (905) can be ensured to be always in contact with the conveyor belt (3);

when the cleaning structure (9) is installed and disassembled for maintenance, firstly, when the lower stop block (1005) is elastically pushed by the elastic piece B (1004) to be contacted with the clamping seat (901), the inclined surface at the head end of the locking head (1003) is aligned with the inner wall of the clamping seat (901), so that automatic locking can be realized when the cleaning head installation seat (902) is installed; secondly, the adjusting arms (1002) are of an L-shaped structure, the two adjusting arms (1002) are symmetrically arranged, the distance between the two adjusting arms (1002) is 5cm, and when the two adjusting arms (1002) are held and tensioned by hands at the same time, the two locking structures (10) are in an unlocking state, so that the dismounting convenience of the cleaning head mounting seat (902) can be improved;

when the change of belt on servo motor (6) band pulley is carried out in lag (5) is dismantled to needs, after finishing through draw-in groove (401) joint on protruding (501) of joint and motor fixing base (4) lag (5), with the fixed orifices on lag (5) and the fixed orifices on motor fixing base (4) each other adjusting well, and joint protruding (501) and draw-in groove (401) constitute joint formula fixed knot jointly and construct, thereby convenience when can improving lag (5) dismouting.
