The utility model adopts the following technical scheme: a dust removing device for a coal mine gob-side entry retaining feeding scraper machine head comprises two side plates which are respectively arranged on two sides of the scraper machine head, the top ends of the two side plates are connected through a top plate, and the front ends of the two side plates are connected through a front baffle;
the side plates, the top plate and the front baffle form a transmission channel for the flexible mold material to pass through, a flexible mold material inlet of the transmission channel faces the feeding direction of the scraper conveyor, and a flexible mold material outlet of the transmission channel faces an inlet of the stirring groove of the flexible mold machine;
and a water supply pipe is further installed on the outer side of the front baffle, a spray head is arranged at the front end of the water supply pipe, the rear end of the water supply pipe is connected to the water supply pipe, and the spraying direction of the spray head faces to an inlet of the stirring tank of the flexible molding machine.
Further, the shape of curb plate is L shape, and has horizontal segment and vertical section, and the rear end of two horizontal segments forms gentle mould material entry jointly with the rear end of roof, and the lower extreme of two vertical sections and the lower extreme of preceding baffle form gentle mould material export jointly.
Further, the top plate is a flat plate or an arc-shaped plate protruding upwards.
Further, the front baffle is a flat plate or an arc plate protruding forwards.
Further, the lower ends of the two horizontal sections are provided with bottom plates.
Furthermore, the rear ends of the two vertical sections are provided with a rear baffle.
The utility model has the advantages that: the utility model discloses a curb plate, roof and preceding baffle form and are used for the transmission path that gentle mould material passes through, make gentle mould material all be in this transmission path from the in-process that scrapes trigger aircraft nose to gentle mould machine stirred tank entry transfer for inside most dust is in this transmission path, and, through the isolation of this transmission path, can also prevent that the stone departure in gentle mould material from hindering the people.
