Abstract
The invention relates to a reamer tooth for a cutter suction dredger, aiming at solving the problems of poor abrasion resistance, easiness for fracture and short service life of the traditional reamer teeth. The reamer tooth comprise a tooth tip and a tooth handle, wherein the tooth tip and the tooth handle are manufactured into a whole, a first groove matched with a tooth seat and a tooth lug are arranged on a rear side face of the tooth handle, the thickness of the top end of the tooth tip of the reamer tooth is 17-19mm, a grinding surface of the tooth tip is a plane, an included angle between the grinding surface and the tooth handle is 5-10 degrees, an end face of the reamer tooth, opposite to the grinding surface, is a back side face which is parallel to a central line of the tooth handle, an included angle between an end face of the tooth tip, adjacent to the back side face, and the central line of the tooth handle is 29-31 degrees, and the back side face and the upper side face of the tooth handle constitute a force bearing face. The reamer tooth disclosed by the invention is used for the cutter suction dredger.
Description
Technical field
The present invention relates to a kind of dredge boat and use the reamer tooth.
Background technology
Cutter suction dredger is the capital equipment that China's dredging industry is used to clear up the geological conditionss such as silt, sandstone and decomposed rock in the navigation channel at present.The reamer tooth adopts wide tooth, drinks the reamer tooth of tooth and three kinds of forms of pointed tooth according to the difference of geological conditions often in construction as the main consumable accessory of cutter suntion dredger, and it is the most commonly used wherein to drink tooth.But,, had a strong impact on the operating efficiency of dredge boat because the wearing no resistance of reamer tooth, frangible and life-span are short.
Since cutter suction dredger to the dredging industry that gets into China; Year surplus in the of existing 30; And the problem in application life of reamer tooth is the key issue of puzzlement dredge boat service efficiency always, no matter be block cast reamer tooth, castingin reamer tooth, or the reamer tooth of surface overlaying does not all reach long-life and low cost.
Summary of the invention
Order of the present invention be for solve the wearing no resistance of existing reamer tooth, frangible and application life short problem, and then provide a kind of cutter suction dredger to use the reamer tooth.
The present invention addresses the above problem the technical scheme of taking to be: a kind of cutter suction dredger of the present invention comprises crown and tooth handle with the reamer tooth; Said crown and tooth handle are processed one; The trailing flank of said tooth handle is provided with first groove and the tooth ear that matches with toothholder; The crown tip thickness of reamer tooth is 17mm～19mm, and the grinding face of said crown is the plane, 5 °～10 ° of the angles between the center line of grinding face and tooth handle; The end face of the reamer tooth relative with grinding face is a dorsal surface; Dorsal surface is parallel with the center line of tooth handle, and the angle between the end face of the crown adjacent with dorsal surface and the center line of tooth handle is 29 °～31 °, and the upper side of said dorsal surface and tooth handle constitutes load-carrying surface.
The invention has the beneficial effects as follows: the crown tip thickness of reamer tooth is 17mm～19mm; Angle between the center line of the end face of crown and tooth handle is 29 °～31 °; Crown loading angle and contact area are improved; Improve reamer tooth wear resistance, made digging of reamer tooth cut efficient and cutter tooth life-span and reach best combination, improved 1～2 times application life; The stressed molded lines of adjustment tooth handle, the thickness of increase tooth handle force area has strengthened bulk strength, prevents fracture, strengthens and resists impact capacity; Surplus is evenly gone in the load-carrying surface both sides, and the reasonable Arrangement structure has guaranteed little quality high strength.
