The invention 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 invention has the beneficial effects that: according to the invention, the side plate, the top plate and the front baffle form the transmission channel for the flexible mold material to pass through, so that the flexible mold material is positioned in the transmission channel in the process of transferring from the scraper machine head to the inlet of the stirring tank of the flexible mold machine, most of dust is positioned in the transmission channel, and stones in the flexible mold material can be prevented from flying out to hurt people through the isolation of the transmission channel.
