Abstract
The invention belongs to coal mine machinery equipment and in particular relates to a novel cutting head spiral drum used for a shearer. The spiral drum comprises a drum, spiral blades, a plurality of pick holders, picks installed on the pick holders, an aqueduct and spray heads, wherein the aqueduct and the spray heads are arranged inside the drum; the spiral blades are arranged around the drum; the pick holders are arranged at the peripheral sides of the drum according to the rise angles of the spiral blades; the spray heads are arranged right below the pick holders; and the outer contour surface formed by tips of the plurality of picks installed on the upper part of the drum is conical. The spiral drum has the following advantages: the picks at the top end of the cutting head are conically arranged to meet the requirement of dinting; the picks are arranged according to the rise angles of the spiral blades, thus prolonging the service life and improving the coaling efficiency of the cutting head; the spray heads connected with the aqueduct arranged in the cutting head are arranged right below the picks, thus effectively reducing dust and creating good construction environment; and as the picks and the pick holders are designed in a split manner and the spray heads are detachable, the spiral drum is convenient to install as a whole and has a simple structure, reasonable design and good coal cutting effect.
Description
Technical field
The invention belongs to coal mine machinery equipment, especially relate to a kind of novel coal-winning machine cutterhead helix drum.
Background technology
The cutterhead helix drum project organization of present existing coal-winning machine is complicated, under the condition of the new coal winning technology of use of some special occasions; Former development machine helix drum effect of loading coal is poor, and productivity ratio is very low, and dust is big and the life-span short.In order to address this problem, improve operating efficiency and improve working environment, be badly in need of a kind of novel helix drum of development.
Summary of the invention
The present invention provides a kind of novel coal-winning machine cutterhead helix drum in order to adapt to novel coal winning technology.
The technical scheme that the present invention adopts is that a kind of novel coal-winning machine cutterhead helix drum comprises cylinder, helical blade; Some toothholders and the pick of upward installing thereof, the aqueduct of cylinder interior, fog-spray nozzle; Be provided with helical blade around the cylinder; Toothholder is arranged at cylinder week side by the helical blade lift angle, and fog-spray nozzle is arranged under the toothholder, and the outer surface that some pick crowns of installing on cylinder top constitute is cone-shaped.
Advantage of the present invention is: the pick on cutterhead top satisfies planted agent's demand by tapered arrangement, and pick is arranged the application life of having improved cutterhead and the efficient of coalingging, built-in aqueduct by the helical blade lift angle; The fog-spray nozzle of its connection is arranged under the pick, can effectively reduce dust, creates good construction environment; Pick and toothholder split design; Fog-spray nozzle is removable, and overall installation is convenient, and is simple in structure, reasonable in design, coal cutting is respond well.
