Detailed description of the invention
Referring to Fig. 1 ~ 7, a kind of Qie Xie vibrating type operating mechanism the present invention relates to and cut wedge vibrating type development machine and coal-winning machine, described mechanism includes cantilever 1, a transverse axis 5 is equipped with in the end of described cantilever 1, this transverse axis 5 is electro-motor or hydraulic motor by this motor 4 of motor 4(being fixed on cantilever 1) drive, concrete, described cantilever 1 is a hollow structure, described transverse axis 5 is positioned in the part of this hollow structure and is set with a travelling gear, the driving shaft of described motor 4 is inserted in the hollow structure of cantilever 1, and the driving shaft of motor 4 drives the travelling gear on transverse axis 5 by the gear transmission structure being arranged in cantilever 1 hollow structure, thereby make motor 4 realize the driving to transverse axis 5, described motor 4 is hydraulic motor, on described transverse axis 5, be set with multiple fan-shaped cutting discs 2, and between adjacent fan-shaped cutting disc 2, be provided with distance cover 3, and on distance cover 3 suits and transverse axis 5, overlap the density that regulates fan-shaped cutting disc 2 to arrange by distance, on the covering of the fan of described fan-shaped cutting disc 2, be provided with wedge 2.1 and joint-cutting cutter 2.2, and joint-cutting cutter 2.2 is knife shape cutter teeth (the KR200/KR230 type knife shape cutter teeth that adopts Kennametal Inc. to produce), described transverse axis 5 is hollow structure, there is an axis of rotation 6 to intert in this hollow structure, and be connected by bearing between the inwall of the outer wall of axis of rotation 6 and transverse axis 5, on the outer wall of described axis of rotation 6, be provided with an eccentric block 7, when use, drive this axis of rotation 6 by motor, motor can be arranged on cantilever or be arranged on other places, after axis of rotation 6 rotations, due to the existence of eccentric block 7, can drive transverse axis 5 to produce together vibration under the effect of centrifugal force.
When use, Qie Xie vibrating type operating mechanism of the present invention and the cantilever 1 of cutting wedge vibrating type development machine and coal-winning machine thereof are hinged on development machine or coal-winning machine, and an oil cylinder is set, this oil cylinder one end is connected with cantilever 1, the other end is fixed on development machine or coal-winning machine, for realizing the angle adjustment to operating mechanism; Meanwhile, in use, also can select according to the actual requirements the mode that works independently of an operating mechanism or the both arms working method of Liang Ge operating mechanism.
Operating principle of the present invention is: motor 4 drives transverse axis 5 to be rotated, thereby drives fan-shaped cutting disc 2 to move in a circle, and now the joint-cutting cutter 2.2 in fan-shaped cutting disc 2 cuts out breach smoothly on coal seam; Simultaneously because development machine or coal-winning machine are also travelling forward, therefore fan-shaped cutting disc 2 can continue to enter coal seam, now the wedge 2.1 in fan-shaped cutting disc 2 is because the little one end of thickness is towards coal seam, thereby it can insert coal seam smoothly, and going deep into along with development machine or coal-winning machine, the stub end of wedge 2.1 gos deep into coal seam gradually, now can be convenient and strength-saving coal cinder is torn and is discerped; Therefore compare traditional structure, this working method, the tensile strength that only need overcome coal seam can conveniently be discerped coal (tensile strength in coal seam is much smaller than the required compressive strength overcoming of traditional approach and shear strength), simultaneously, the vibrating mechanism being formed by axis of rotation 6 and eccentric block 7 can be more convenient coal cinder is shaken off, therefore operating efficiency is high; The mode of simultaneously carrying out cutwork face unlike tradition, is only to discerp coal seam, thereby can not produces a large amount of dust, is conducive to improve construction environment.
