Preferably, for the fixed plate under tight condition, its outer side edges is vertical with sleeve pipe.
Beneficial effect using above technical scheme is：The feeding chute anti-block apparatus of structure of the present invention, can realize and
Shi Faxian chute blockings, reduce the generation of the accidents such as the vexed head of coal stream, and the safety reduced from root in production process is hidden
Suffer from, improve the security of post operation personnel, enhance the continuity of production, stability, improve worker's working environment, greatly
The big labor intensity for reducing worker.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of infrared sensing switch.
Wherein, 1-- feeding chutes, 2-- infrared sensing switch, 3-- mounting holes, 4-- discharging openings, 5-- sleeve pipes, 6-- positioning
Plate, 7-- fixed plates, 8-- stepped holes, 9-- positioning chimb, 10-- springs, 11-- threaded portions, 12-- regulating blocks.
Embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 shows the embodiment of the present invention：A kind of anti-block apparatus of feeding chute 1, the anti-block apparatus are arranged on down
Expect the inside of chute 1, the anti-block apparatus is infrared sensing switch 2, and the side wall of the feeding chute 1 is provided with mounting hole 3, and this is red
Outside line inductive switch passes through mounting hole 3, and the discharging opening 4 of inductive head towards the feeding chute 1 of infra-red sensor switch is set；It is red
Distance between the inductive head and discharging opening 4 of outside line inductive switch is less than the distance of reaction of infra-red sensor switch.
Mounting hole 3 is obliquely installed, and sleeve pipe 5 is provided with the mounting hole 3, and the infra-red sensor switch is arranged on sleeve pipe 5
It is interior；One end of sleeve pipe 5 is provided with location-plate 6, and its other end is provided with the fixed plate 7 of threaded connection, fixed plate 7 under tight condition,
Its outer side edges is vertical with sleeve pipe 5.
One end inner chamber of the close location-plate 6 of sleeve pipe 5 is provided with stepped hole 8, and the infra-red sensor switch is close to sensing
