Description
Technical field
The utility model belongs to the belt-conveying technical field of raw coal, relates to the head head piece of belt transporter, particularly relates in raw coal belt-conveying process the mechanical device that the head head piece is dredged after being stopped up by boulder or unclassified stores.
Background technology
At present, home and abroad colliery passes through for preventing boulder in raw coal lifting or transportation, usually the strip channel that is comprised of some bar shapeds rods or square rail can be set at belt conveyer head head piece place, so that boulder is separated.But the phenomenon that the boulder obstruction head head piece in the raw coal usually can occur so again.When boulder stops up the head head piece, can only be that the method that relies on artificial hook to draw is dredged at present, dredging method falls behind, and operate dangerously, and elapsed time is long, needs personnel many, causes easily belt to shut down, and affects production.
Summary of the invention
The purpose of this utility model provides a kind of raw coal belt-conveying head head piece dredger, with the boulder that stops up on the automatic dredging head head piece.
Raw coal belt-conveying head head piece dredger of the present utility model is installed under the bar rod of head piece bar rod below on the chute, by Electrohydraulic push rod, pipe link, transmission shaft, the arm of force, dredging plate base and dredging plate form, described Electrohydraulic push rod is fixed on the outside of chute under the bar rod, described pipe link is movably connected on the piston rod of Electrohydraulic push rod, described transmission shaft is installed on the side plate of chute under the bar rod, the external side end of transmission shaft is captiveed joint with pipe link, the described arm of force is positioned at side plate one side that chute under the bar rod is equipped with transmission shaft, the arm of force one end is fixedly connected on the medial extremity of transmission shaft, the other end is captiveed joint with dredging plate base, following current pig's tongue rod direction is fixedly connected with some dredging plates on dredging plate base, and the installation site of described dredging plate is corresponding to the gap between the head piece bar rod.
The utility model chute drop end under the bar rod is provided be used to the groove of parking dredging plate base, when dredger is not worked, the arm of force, dredging plate base and the dredging plate that are positioned at chute under the bar rod nestle up under the bar rod chute drop end and park, neither can affect coal stream and pass through, the coal stream that also can not be passed through is pounded damage.
And then, the utility model also under the bar rod above the described transmission shaft chute drop end be provided with the transmission shaft backplate, with the protection transmission shaft, prevent that transmission shaft from being pounded damage, and coal dust enters into transmission shaft.
The utility model chute drop end under the bar rod is fixed with the Electrohydraulic push rod mounting, in the both sides of Electrohydraulic push rod the axle ear is installed, and described Electrohydraulic push rod is fixedly mounted on the Electrohydraulic push rod mounting by the axle ear of himself installing.Preferably, the piston rod of described pipe link and Electrohydraulic push rod front end is hinged.
The utility model also under described rod the side plate of chute bearing seat is installed, described transmission shaft is installed under the bar rod in the bearing seat on the chute side plate, and is provided with gland in the outside of bearing seat, plays the effect that prevents the transmission shaft displacement.
Preferably, the described arm of force is to captive joint with dredging plate base with the medial extremity of transmission shaft respectively by bolt.
In the belt-conveying process of raw coal, after the belt conveyer head head piece is by boulder or other feed blocking, Electrohydraulic push rod promotes pipe link, pipe link drives transmission shaft and rotates, the rotation of transmission shaft drives the arm of force and rises, and the dredging plate rises, and passes head piece bar rod tamper is provoked, the tamper following current pig's tongue rod of being provoked flows down, thereby reaches the effect of dredging head piece.
When dredger of the present utility model stops up the belt conveyer head head piece at boulder, can be fast, safe, solve belt-conveying head head piece blockage problem efficiently, use manpower and material resources sparingly.
Dredger of the present utility model is not when working, and its part that is positioned at chute under the bar rod is parked near chute drop end under the belt feeder head bar rod, neither can affect passing through of coal stream, and the coal stream that also can not be passed through is pounded damage.And having adopted an arm of force to connect the arrangement structure of a plurality of dredging plates, the arm of force is installed near the side plate of chute under the bar rod, and is very little to the interference effect of coal stream in the arm of force and dredging plate rising working process, do not affect passing through and producing of main coal stream.
Dredger of the present utility model adopts Electrohydraulic push rod as operation power, and not only volume is little, lightweight, and speed of response is fast, power saving; The arm of force is the entity steel structure, and volume is little, intensity is high; The arm of force is connected with bolt with dredging plate underframe, is conducive to install and change.
