[0007] Preferably, the connecting frame is a hollow channel steel frame with the opening facing downward.

[0008] Preferably, the two ends of the connecting frame are fixedly connected to separate chain links on the two traction chains.

[0009] Preferably, the material fishing rod is a bent steel bar perpendicular to the connecting frame, and the upper end of the material fishing rod is bent to one side of the upper end of the conveyor frame.

[0010] Preferably, the inner side of the baffle is provided with a connecting plate of integral structure, and the baffle is detachably installed on the connecting frame through the connecting plate and bolts.

[0011] Preferably, the baffle is a stainless steel bent sheet.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model discloses a baffle is installed in the both ends of the connecting frame of traction chain drive in turn and overlaps, and the baffle is shielded in the outside of traction chain, can block the raw material close and the card into traction chain again, does not influence traction chain normal operation, reaches the effect of the safety protection of traction chain, solves the problem that raw material falls into the chain and influences the normal operation of the conveyor when the existing chain plate conveyor for pulping raw material loading works.
