The chain wheel body 2 is provided with a lifting chain plate 3 on the upper end for vertical rotation of the material lifting and feeding. The lifting chain plate 3 is provided with a pneumatic chain clamping plate 5 on the inner side through a fixing plate 4 at both ends for clamping and fixing the lifting chain plate 3 caused by dust accumulation in the lifting bin body 1. The lifting chain plate 3 is clamped and maintained in a state when the chain is broken. The fixing plate 4 is provided with a fixing clamp plate 6 on the front and back of both ends, which is clamped on both sides of the lifting chain plate 3 and has an L-shaped structure. The fixing clamp plate 6 clamps and fixes the lifting chain plate 3 on both sides to prevent the lifting chain plate 3 from separating from the chain wheel body 2 and causing material accumulation in the lifting bin body 1. The fixing clamp plate 6 is provided with a cylinder component 7 corresponding to the position of the fixing plate 4 on both sides. The pneumatic chain clamping plate 5 is clamped and clamped when the chain is broken. A large amount of material accumulated in the lifting bin body 1 causes equipment failure. The lifting bin body 1 is provided with a feeding hopper plate 8 at the bottom end of one side for inclined feeding of the material. The lifting bin body 1 is provided with a discharge hopper plate 9 at the upper end of the other side for output of the lifting and conveying material. The lifting and conveying of the material is facilitated.

[0023] The pneumatic chain clamp plate 5 is uniformly provided with clamping anti-skid teeth 10 on the inner side of the lifting chain plate 3, which avoids the lifting chain plate 3 from falling off. The other side of the pneumatic chain clamp plate 5 is fixed on the piston rod of the cylinder part 7, so that the pneumatic chain clamp plate 5 moves instantaneously to clamp and fix the lifting chain plate 3. The lifting chain plate 3 is uniformly provided with a lifting hopper 11 on the surface for inputting and outputting material to the feeding hopper plate 8, which is used for transmitting material. The lifting chain plate 3 is arranged in the inner side of the L-shaped fixed clamp plate 6 on both sides, which realizes instant clamping and fixing of the lifting chain plate 3. The bottom end of the outer side of the lifting bin body 1 is provided with a fixed strip plate 12. The upper end of the fixed strip plate 12 is provided with a control box 13.
