Description
技术领域technical field

当前的颚式破碎机模拟动物的两颚运动,其通过电机驱动动颚摆动,使得动颚组与定颚相互咬合,实现对物料的破碎。在动颚组摆动过程中,出料口调节机构用于支撑动颚组并调节动颚组与定颚架之间的出料口大小,动颚拉紧缓冲机构用于拉紧动颚组并有缓冲效果。The current jaw crusher simulates the movement of the two jaws of animals. It drives the movable jaw to swing through the motor, so that the movable jaw set and the fixed jaw engage with each other to achieve crushing of materials. During the swinging process of the movable jaw group, the discharge port adjustment mechanism is used to support the movable jaw group and adjust the size of the discharge port between the movable jaw group and the fixed jaw frame, and the movable jaw tension buffer mechanism is used to tighten the movable jaw group and There is a cushioning effect.
颚式破碎机的定颚架包括定颚体、固定在定颚体上的定颚衬板,定颚衬板刚性连接在定颚体上。在破碎石料时,定颚和动颚受到挤压会产生强烈震动,刚性连接的结构会将震动传递至整个机架上,从而导致设备震感强烈,影响安全生产;单腔破碎机还存在破碎效率低,结构上需要笨重的飞轮,进料口无法调整等缺点。The fixed jaw frame of the jaw crusher includes a fixed jaw body and a fixed jaw liner fixed on the fixed jaw body, and the fixed jaw liner is rigidly connected to the fixed jaw body. When crushing stones, the fixed jaw and the movable jaw will generate strong vibrations when they are squeezed, and the rigidly connected structure will transmit the vibrations to the entire frame, resulting in strong vibrations for the equipment and affecting safe production; single-cavity crushers also have crushing efficiency. Low, heavy flywheel is required in structure, and the feed inlet cannot be adjusted.

上述实施例中,每个所述位移限制件包括一个“[”型调节板14、一个调节螺栓19;调节螺栓19依次穿过“[”型调节板14、第二支撑板152,并顶触滑块13的另一个直角面。调节螺栓19通过拧紧或者放松调节滑块13与动颚5之间的距离:当拧紧调节螺栓19时,调节螺栓19顶触着滑块13向靠近动颚5的方向移动,滑块13与动颚5之间的距离变小,使得肘板11倾角增大,破碎腔出料口变大,被破碎的物料粒度相应地变大;当放松调节螺栓19时,肘板顶触滑块13向远离动颚5的方向移动,滑块13与动颚5之间的距离变大,使得肘板11倾角减小,破碎腔出料口变小,被破碎的物料粒度相应地变小。可见,本发明通过调节螺栓19、滑块13、肘板11等组件的相互配合,实现了物料破碎粒度大小的调整。In the above embodiment, each of the displacement limiting members includes a "["-shaped adjusting plate 14 and an adjusting bolt 19; Another right angle face of slide block 13. The adjustment bolt 19 adjusts the distance between the slider 13 and the movable jaw 5 by tightening or loosening: when the adjustment bolt 19 is tightened, the adjustment bolt 19 touches the slider 13 and moves toward the direction close to the movable jaw 5, and the slider 13 and the movable jaw 5 The distance between the jaws 5 becomes smaller, so that the inclination angle of the toggle plate 11 increases, the discharge opening of the crushing cavity becomes larger, and the particle size of the crushed material increases correspondingly; when the adjusting bolt 19 is loosened, the toggle plate touches the slider 13 in the direction Moving away from the movable jaw 5, the distance between the slider 13 and the movable jaw 5 becomes larger, so that the inclination angle of the toggle plate 11 decreases, the discharge opening of the crushing chamber becomes smaller, and the particle size of the crushed material becomes smaller accordingly. It can be seen that the present invention realizes the adjustment of the crushing particle size of the material through the mutual cooperation of the adjusting bolt 19, the slider 13, the toggle plate 11 and other components.
上述实施例中,定颚10上安装有定颚衬板9,定颚衬板9通过螺栓固定在定颚10上。动颚5上安装有动颚衬板8,动颚衬板8通过穿设有螺栓7的压块6固定在动颚5上,压块6设置在动颚5的靠近传动机构的位置处。当动颚衬板8与定颚衬板9被磨损后,可以根据其磨损程度更换新的动颚衬板8与定颚衬板9,这样就保护动颚5与定颚10不被磨损,延长本发明所述对称双腔颚式破碎机的使用寿命。In the above embodiment, the fixed jaw liner 9 is installed on the fixed jaw 10, and the fixed jaw liner 9 is fixed on the fixed jaw 10 by bolts. A movable jaw liner 8 is installed on the movable jaw 5, and the movable jaw liner 8 is fixed on the movable jaw 5 by a pressing block 6 pierced with bolts 7, and the pressing block 6 is arranged at a position close to the transmission mechanism of the movable jaw 5. When the movable jaw liner 8 and the fixed jaw liner 9 are worn out, the new movable jaw liner 8 and the fixed jaw liner 9 can be replaced according to the degree of wear, thus protecting the movable jaw 5 and the fixed jaw 10 from being worn out. The service life of the symmetrical double-cavity jaw crusher described in the present invention is prolonged.
本发明中,外部驱动机构为由高频换向液压缸驱动的液压摆动马达或齿轮齿条高频换向液压缸。齿轮齿条高频换向液压缸包括驱动齿轮、齿条、高频换向液压缸,齿条安装于高频换向液压缸上,驱动齿轮安装在所述传动轴上,驱动齿轮与齿条啮合。实际应用中,采用液压驱动可以方便地调整摆动幅度和摆动频率,从而进料口大小可调,并实现过载保护。In the present invention, the external driving mechanism is a hydraulic swing motor driven by a high frequency reversing hydraulic cylinder or a rack and pinion high frequency reversing hydraulic cylinder. The rack and pinion high-frequency reversing hydraulic cylinder includes a driving gear, a rack, and a high-frequency reversing hydraulic cylinder. The rack is installed on the high-frequency reversing hydraulic cylinder. The driving gear is installed on the transmission shaft. The driving gear and the rack engage. In practical applications, the hydraulic drive can be used to easily adjust the swing amplitude and swing frequency, so that the size of the feed inlet can be adjusted and overload protection can be realized.
需要说明的是,本实施例中的小齿轮所谓的小是其弧度相对于扇形架带有齿的下边圆弧的弧度而言的,没有其他不清楚的含义。It should be noted that the so-called small gear in this embodiment refers to the radian of its radian relative to the arc of the lower edge of the sector frame with teeth, and there is no other unclear meaning.
综上所述,本发明所述对称双腔颚式破碎机在破碎硬质物料时,传动机构将外部动力传输至动颚,动颚通过摆动破碎和输出物料;本发明中,对称的两个单腔颚式破碎机在外部动力不增强的情况下同时工作:当一个单腔颚式破碎机进行物料破碎时,另一个单腔颚式破碎机输出破碎后的物料。由此可见,本发明所述对称双腔颚式破碎机没有空回行程,这就使得其工作效率获得了较大的提高。同时,由于两个单腔颚式破碎机对称,许多零件相同,便与加工,故本发明所述对称双腔颚式破碎机容易加工、安装、调整,且结构简单、造价较低。进一步地,外部驱动机构依次通过传动轴、小齿轮、扇形架实现减速和力的放大,可减少上一级传动的传动比,且不需要笨重的飞轮,简化了机构,减轻了设备重量;从而带动着动颚进行复杂摆动,也是提高工作效率的原因之一。In summary, when the symmetrical double-chamber jaw crusher of the present invention crushes hard materials, the transmission mechanism transmits the external power to the movable jaw, and the movable jaw crushes and outputs the material by swinging; in the present invention, the two symmetrical The single-cavity jaw crushers work at the same time without increasing the external power: when one single-cavity jaw crusher crushes materials, the other single-cavity jaw crusher outputs the crushed materials. It can be seen that the symmetrical double-cavity jaw crusher in the present invention has no empty return stroke, which greatly improves its working efficiency. At the same time, because the two single-cavity jaw crushers are symmetrical, many parts are the same, so it is easy to process, so the symmetrical double-chamber jaw crusher of the present invention is easy to process, install, and adjust, and has a simple structure and low cost. Furthermore, the external drive mechanism achieves deceleration and force amplification through the transmission shaft, pinion, and sector frame in turn, which can reduce the transmission ratio of the upper stage transmission, and does not require a heavy flywheel, which simplifies the mechanism and reduces the weight of the equipment; thus It drives the movable jaw to perform complex swings, which is also one of the reasons for improving work efficiency.
