The conveying belt 5.3 of the belt machine 5 is connected with the output end of the driving member 5.2 in sequence after being led out from the belt storage bin 5.1, passing through the belt reversing mechanism 4 on the first turning support 1, the support frame 2 and the belt reversing mechanism 4 on the second turning support 3, and moves along the conveying direction under the action of the driving member 5.2 to perform the conveying operation. In actual operation, the included angle between the conveying belt 5.3 and the second turning support 3 can be changed by moving the first turning support 1 and the support frame 2, so that the free turning within the range of 0° to 180° is realized, so as to adapt to the narrow and complex space operation. In addition, the extension direction of the conveying belt 5.3 can be changed by the belt reversing mechanism 4, so as to adapt to the change of the included angle between the conveying belt 5.3 and the second turning support 3.
