The present invention discloses a trenching machine for concrete asphalt ground, including a frame, a power unit, a traveling mechanism, a cutting and crushing device, a trenching and soil dividing device and a hydraulic system. There are two traveling mechanisms, which are symmetrically arranged on both sides of the frame, and the power unit is connected to the traveling mechanism. The trenching and soil dividing device is arranged on the rear side of the vehicle body. The cutting and crushing device is arranged at the front end of the frame through a front support frame, and includes a transmission shaft, a crushing assembly, and a cutting blade. The transmission shaft is connected to the power unit through a first transmission belt. The cutting blade is arranged on the cutting blade drive shaft, and the cutting blade drive shaft is connected to the front support frame through a cradle. The crushing assembly includes a sleeve, an impact rod and an eccentric wheel. The impact rod is vertically movably arranged below the transmission shaft through the sleeve, and an impact head is arranged at the lower end thereof. The eccentric wheel is arranged on the transmission shaft. The structural design of the present invention is reasonable, cutting and crushing are performed first, and then rapid excavation is performed. The trenching depth can be adjusted to achieve deep excavation, replacing manual trenching, saving time and labor, and having high work efficiency.

The utility model provides a kind of mechanical gripper of game machine and game machine, the mechanical gripper of game machine includes: gripper mechanism and gripper transmission control mechanism, gripper mechanism includes installation base, vertical arm assembly, cantilever assembly, excavator assembly and rotary drive assembly.Relative to prior art, the mechanical gripper of the utility model's game machine can independently drive excavator assembly, cantilever assembly and vertical arm assembly to move respectively, so excavator assembly, cantilever assembly and vertical arm assembly can move synchronously, can accurately complete the opening and closing action of grab bucket mechanism in shorter time, so that the digging speed is faster, can improve the experience of player, and using each elastic component can improve the stability of excavator assembly, cantilever assembly and vertical arm assembly movement, avoid grab bucket mechanism to sway, the linear transmission precision of sliding assembly is higher, can make the action of excavator assembly more accurate, also have stroke detection function, high safety, low failure rate.
