Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The technical problems of the embodiment are as follows: when the situation that anti-blocking application cannot be performed through vibration occurs, the auxiliary diversion application is lacking, and the application cannot be performed under the situation that coal is required to be discharged in an emergency;

in order to solve the technical problem, the utility model provides a continuous coal feeding device with a coal dropping pipe blockage, which is convenient for forming lateral diversion guide in the process that the first coal dropping pipe 2 is blocked and can not be dredged, thereby forming continuous dredging coal feeding and being convenient for forming another coal dropping application.

Referring to fig. 1-3, a coal dropping pipe blocking continuous coal feeding device comprises a coal bin 1, wherein one side of the coal bin 1 is fixedly connected with an emergency diversion continuous coal feeding structure 4 through a flange, the emergency diversion continuous coal feeding structure 4 comprises an auxiliary coal guiding pipe 5, a speed reducer 6, a first motor 7, a first section auger 8 and a second coal dropping pipe 9, one side of the outer wall of the coal bin 1 is fixedly connected with the auxiliary coal guiding pipe 5, one side of the auxiliary coal guiding pipe 5 is fixedly connected with the speed reducer 6, one side of the speed reducer 6, far away from the auxiliary coal guiding pipe 5, is fixedly connected with the first motor 7 through a screw, the output end of the speed reducer 6 is fixedly connected with the first section auger 8, and the bottom end of the auxiliary coal guiding pipe 5 is fixedly connected with the second coal dropping pipe 9 through the flange.

The first section auger 8 is rotatably connected with the auxiliary coal guide pipe 5.

The bottom fixedly connected with first coal breakage pipe 2 of coal bunker 1, the outside fixedly connected with of first coal breakage pipe 2 is assisted to dredge pipe 3.

The inner side upper wall of the auxiliary coal guide pipe 5 is fixedly connected with an auger hanging bracket 10 through a screw, and the inner side of the auger hanging bracket 10 is rotationally connected with a roller bearing.

One end of the first section auger 8 far away from the speed reducer 6 is fixedly connected with a roller bearing on the inner side of the auger hanging frame 10, and one end of the roller bearing on the inner side of the auger hanging frame 10 far away from the first section auger 8 is fixedly connected with a second section auger 11.
