The specific embodiment
As Fig. 1, a kind of band detecting device shown in Fig. 2, it comprises side plate I 9 and the side plate II 10 that is arranged on belt feeder frame both sides, rotating shaft I 11 and rotating shaft II 12 are installed between side plate I and side plate II, in rotating shaft I 11, be fixed with rotating beam 13, on upper rotating beam 13, be fixed with belt and support 13-1, in rotating shaft II 12, be fixed with lower rotating beam 14, on lower rotating beam 14, be fixed with lower belt and support 14-1, the end of described rotating shaft I 11 is fixed with when broken belt and provides the counterweight 16 that rotates up power to rotating shaft I, between described side plate I 9 and side plate II 10, be fixed with and arrest beam 15, on arrest beam and be positioned at described rotating shaft I top, when belt normally moves, described upper rotating beam 13 is in horizontal stationary station.
The inner side of described side plate I 9 is fixed with explosion-proof travel switch base I 5, in explosion-proof travel switch base I 5, explosion-proof travel switch I 1 is installed, the inner side of described side plate II 10 is fixed with explosion-proof travel switch base II 6, in explosion-proof travel switch base II 6, be fixed with explosion-proof travel switch II 3, described explosion-proof travel switch I 1 and explosion-proof travel switch II 3 are positioned at the top near described upper rotating beam horizontal stationary station, the contact of explosion-proof travel switch I 1 and explosion-proof travel switch II 3 points to described rotating shaft I 11, one end of rotating shaft I is fixed with trigger mechanism base I 7, in trigger mechanism base I 7, be fixed with the triggering shifting block I 2 corresponding with explosion-proof travel switch I 1, the other end of rotating shaft I is fixed with trigger mechanism base II 8, in trigger mechanism base II 8, be fixed with the triggering shifting block II 4 corresponding with explosion-proof travel switch II 3, when described upper rotating beam 13 is in horizontal stationary station, described triggering shifting block I 2 and trigger between shifting block II 4 explosion-proof travel switch corresponding with them and leave gap.
