Close.
By adopting the above-described technical solution, the utility model has the advantages that compared with prior art：
1st, the utility model is connected coke oven mouth and storage pond by a chute controlled by passage oil cylinder, overturning oil cylinder
Pick up and, make to be transported to storage pond from the pusher side Last Coke that coke oven mouth drops out by scrapper conveyor；
2nd, the utility model realizes machinery recovery Last Coke, significantly reduces the labor intensity of operation employee, while also keep away
Exempt from operation employee to work in high temperature environments.
Brief description of the drawings
Fig. 1 is top view of the present utility model.
Fig. 2 is the left view of the utility model chute.
Fig. 3 is the utility model scrapper conveyor, storage tank schematic diagram.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples：
This coke oven Last Coke retracting device as shown in Fig. 1 ~ Fig. 2, including chute 9, the section of chute 9 is opening upwards
Groove shapes, combined by line part and rake, chute 9 is provided with the He of side wheel 17 moved in the track 6 of groove type
The front wheel 10 of the top bottom of chute 9 is located at, the top of chute 9 is connected with horizontal push rod 7, horizontal push rod 7 and the activity of passage oil cylinder 2
Connection, the top of chute 9 are provided with overturning oil cylinder 1, and the piston rod of overturning oil cylinder 1 connects a drawing for being located at the horizontal bottom of push rod 7
Hook 8；The lower section of chute 9 is provided with scrapper conveyor 15, the connection storage of scrapper conveyor 15 pond 13；Passage oil cylinder 2 and overturning oil cylinder 1 are respectively equipped with
Stopping means, the stopping means of passage oil cylinder 2 include the stroke collision block and limit switch 4,5 for being located at the horizontal left end of push rod 7；Upset
The stopping means of oil cylinder 1 includes the stroke collision block 11 and spacing 12 being located on the piston rod of overturning oil cylinder 1；Side wheel 17 totally two
It is right, the both sides of the line part of chute 9 are located at by roller bearing interval, front wheel 10 has one, is located at the bottom of the rake of chute 9
Portion；Track 6 is provided with the breach that width is more than the diameter of side wheel 17, when overturning oil cylinder 1 is allowed to tilt by the pull-up chute 9 of drag hook 8
When, the side wheel 17 in front can be lifted from the breach of track 6；The tailpiece of the piston rod of passage oil cylinder 2 is connected with connection ring 3,
The left end of horizontal push rod 7 is provided with the plug of insertion connection ring 3, when the plug of horizontal push rod 7 inserts connection ring 3, passage oil cylinder 2
When piston rod stretches out, by chute connecting rod 7 chute 9 can be driven to move forward；Scrapper conveyor 15 is provided with tank, and storage pond is provided with valve
