Embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing, it is clear that described
Embodiment is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, sheet
The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality
Novel protected scope.
Fig. 1 and Fig. 2 are refer to, Fig. 1 is a kind of specific implementation of driven pulley chain disconnecting prevention structure provided by the utility model
The structural representation of mode；The structure of chain scraper type feeders of the Fig. 2 where driven pulley chain disconnecting prevention structure shown in Fig. 1 is shown
It is intended to.
In a kind of embodiment, driven pulley chain disconnecting prevention structure provided by the utility model is used for chain scraper type
