The specific embodiment
Referring to Fig. 1 ~ 4, a kind of development machine that the utility model relates to and coal-winning machine are with cutting wedge vibrating type operating mechanism, described mechanism includes support arm 1, there is a rotating shaft 5 end of described support arm 1 by the bearing cross-under, this rotating shaft 5 is driven by the motor 4 that is fixed on the support arm 1, concrete, described support arm 1 is a hollow structure, described rotating shaft 5 is positioned on 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 support arm 1, and the driving shaft of motor 4 is by being arranged at the travelling gear on the gear transmission structure drive shaft 5 in support arm 1 hollow structure, thereby so that motor 4 is realized the driving of countershaft 5, described motor 4 is hydraulic motor, be set with a plurality of bottom jibs 2 in the described rotating shaft 5, and be provided with distance cover 3 between the adjacent bottom jib 2, this is apart from cover 3 suits and the rotating shaft 5, described bottom jib 2 includes the collar that is set in the rotating shaft 5, and evenly be provided with a plurality of sector structure parts 2.1 on the outer circumference surface of this collar, described sector structure part 2.1 be provided with wedge 2.2 on two covering of the fans up and down, and wedge 2.2 away from an end thickness of the collar less than the thickness near an end of the collar, be provided with a plurality of picks 2.3 on the cambered surface of described sector structure part 2.1, and pick 2.3 is knife shape cutter teeth (the KR200/KR230 type knife shape cutter teeth that adopts Kennametal Inc to produce), described rotating shaft 5 is hollow structure, there is an axis of rotation 6 to intert in this hollow structure, and link to each other by bearing between the inwall of the outer wall of axis of rotation 6 and rotating shaft 5, be provided with a vibrating mass 7 on the outer wall of described axis of rotation 6; During use, drive this axis of rotation 6 by motor, motor can be installed on the support arm or be installed in other places, after axis of rotation 6 rotations, because the existence of vibrating mass 7 can drive rotating shaft 5 and produce together vibration under the effect of centrifugal force.
During use, the utility model development machine and coal-winning machine are hinged on development machine or the coal-winning machine with the support arm 1 of cutting wedge vibrating type operating mechanism, and an oil cylinder is set, this oil cylinder one end links to each other with support arm 1, the other end is fixed on development machine or the coal-winning machine, is used for realization to the angle adjustment of operating mechanism; Simultaneously, 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 two operating mechanisms.
Operating principle of the present utility model is: motor 4 drive shafts 5 are rotated, and move in a circle thereby drive bottom jib 2, and the pick 2.3 on the bottom jib 2 cuts out breach in the coal seam smoothly at this moment; Simultaneously since development machine or coal-winning machine also travelling forward, therefore bottom jib 2 can continue to enter the coal seam, this moment on the bottom jib 2 wedge 2.2 since the little end of thickness towards the coal seam, thereby it can insert the coal seam smoothly, and going deep into along with development machine or coal-winning machine, the stub end of wedge 2.2 gos deep into the coal seam gradually, and this moment can be convenient and strength-saving coal cinder is torn discerped; Therefore compare traditional structure, this working method, the tensile strength that only need overcome the coal seam can conveniently be discerped coal (tensile strength in coal seam is much smaller than the required compressive strength that overcomes of traditional approach and shear strength), simultaneously, the vibrating mechanism that is consisted of by axis of rotation 6 and vibrating mass 7 can be more convenient coal cinder is shaken so high efficiency; Carry out simultaneously the mode of cutwork face unlike tradition, only be to discerp the coal seam, thereby can not produce a large amount of dust, be conducive to improve construction environment.
