The invention provides a tail device of a chain conveyor, which comprises a tail frame, wherein a supporting seat is arranged on the tail frame, a bearing seat is arranged on the supporting seat, a screw rod is arranged on the bearing seat, a tail wheel is arranged on the bearing seat, the tail wheel is embedded on the bearing seat, the tail end of the screw rod is connected to the tail wheel, external power drives the tail wheel to move through the screw rod, a guide rail is arranged on the supporting seat, a tail shaft is embedded at the tail part of the tail wheel, a bearing is arranged on the tail shaft, the tooth part of the tail wheel adopts a tooth dividing block, the tooth part of the tail wheel is embedded together with the tail shaft through a pin key, and felt rings are arranged on the bearing and the tail shaft.

The further improvement lies in that: the stifle is installed in the bearing outside, inlay between stifle and the bearing and be equipped with the retaining ring, the dismouting of being convenient for.

The further improvement lies in that: the connecting part of the tail wheel and the screw rod is provided with a sliding block, the sliding block is arranged on the inner side of the supporting seat, and the outer side of the supporting seat is provided with a spring.

The further improvement lies in that: the guide rail is installed on the supporting seat through a guide rail bolt, and a gasket is installed between the guide rail bolt and the guide rail.

The further improvement lies in that: and a screw is embedded at the joint of the tail wheel and the tail shaft, and a check ring is also arranged between the screw and the tail shaft.

The further improvement lies in that: an oil cup is arranged on the blank cap, and a rotary detector is further arranged on the blank cap.

The invention has the beneficial effects that: the felt ring is arranged between the tail bearing and the tail shaft of the chain conveyor, and the outer part of the bearing is provided with the blank cap, so that the sealing can be effectively formed, the dust can be seamlessly drilled, the fine dust and the flying toxic materials can be conveyed, the working condition can be improved, and the environmental pollution can be prevented. The oil cup is arranged on the blank cap, the composite calcium-based lubricating grease is coated on the bearing seat, the bearing and the screw rod, the lubricating grease is effectively prevented from leaking from a bearing part, the normal lubrication of the bearing is ensured, the rotary detector is arranged on the blank cap of the tail shaft, when the tail part device of the chain conveyor is locked and rotated, the rotation is blocked, the belt slips and the transmission belt falls off, the transmission shaft rotates slowly or stops rotating, the rotary detector rotates slowly or stops rotating along with the transmission shaft, the signal is connected into the central control room, the related problems can be effectively and timely processed, and the effects of ensuring production and protecting equipment are simple and practical in structure and stable and reliable in performance.
