[utility model content]
The purpose of this utility model is to provide a kind of cement pavement milling machine, to solve the problems of the technologies described above.The utility model cement pavement milling machine can solve traditional milling machine can not the shortcoming of the larger cement pavement of milling rigidity.
To achieve these goals, the utility model adopts following technical scheme:
A kind of cement pavement milling machine, comprises tractor, impact head and cutterhead; Cutterhead is connected in the frame of tractor by cutterhead elevating mechanism; Impact head moves back and forth driving mechanism by impact head and is connected in the frame of tractor; Frame is provided with the pilot sleeve led to impact head.
Further, cutterhead elevating mechanism comprises telescopic oil cylinder, connecting rod I and axle; Telescopic oil cylinder one end is hinged in frame by contact A, and the other end is hinged on connecting rod I by contact C; Connecting rod I one end is hinged in frame by contact B, and the other end is hinged by contact D and axle; Cutterhead is fixed on axle.
Further, impact head reciprocating motion driving mechanism comprises hydraulic motor and bent axle; Impact head top becomes cylindrical, and conically, impact head top is connected by pin with connecting rod II in lower surface, and impact head can rotate relative to connecting rod II; Crankshaft two end is supported by block bearing I, is connected by shaft coupling with hydraulic motor; The trunnion of bent axle coordinates with connecting rod III gap, can relatively rotate; Connecting rod III connects connecting rod II by shock-absorbing spring.
Further, the two end supports of axle is on spring bearing II; Driven by belt wheel.
Further, described a kind of cement pavement milling machine comprises multiple impact head and cutterhead.
Further, in the direction of advance of tractor, impact head is arranged at and cutterhead front.
Relative to prior art, the utility model has following beneficial effect:
Bent axle rotates under the drive of CD-ROM drive motor, thus drive is constantly moved with the connecting rod about III of trunnion matched in clearance, by pin I, shock-absorbing spring, pin II, connecting rod II and pin III, impact head is driven constantly to pump in pilot sleeve, each impact head constantly impacts the larger cement pavement of rigidity, the cement pavement being subject to impact shock produces crack, structure is destroyed, then carry out milling with the cutterhead cement pavement that structure is destroyed to being subject to impact shock, the cement pavement larger to rigidity carries out excavation renovation.Impact head and cutterhead are in a row arranged, work continuously, and operating efficiency is high.

Below in conjunction with drawings and Examples, particular content of the present utility model is described in more detail.
[detailed description of the invention]
Below provide specific embodiment of the utility model, it should be noted that the utility model is not limited to following specific embodiment, all equivalents done on technical scheme basis all fall into protection domain of the present utility model.
Refer to shown in Fig. 1, a kind of cement pavement milling machine of the utility model, comprise can in pilot sleeve 16 reciprocating impact head 22, the cutterhead 1 of the larger cement pavement of bent axle 12, telescopic oil cylinder 2 and milling rigidity that drives impact head 22 to move reciprocatingly.
Impact head 22 top becomes cylindrical, and lower surface conically, is connected by pin III 20 with connecting rod II 17, and impact head 22 can be rotated relative to connecting rod II 17; Pilot sleeve 16 is fixed in frame, for the impact head 22 moved reciprocatingly up and down play the guiding role.
Bent axle 12 two ends are supported by block bearing I 11, are connected by shaft coupling 10 with hydraulic motor 9; The trunnion of bent axle 12 and connecting rod III 19 matched in clearance, can relatively rotate.
Telescopic oil cylinder 2 one end is hinged in frame by contact A3, and the other end is hinged on connecting rod I 6 by contact C7.
Cutterhead 8 is fixed on axle 21; The two end supports of axle 21 is on spring bearing II 23; Driven by belt wheel 24; Axle 21 and connecting rod I 6 are hinged by contact D8, and connecting rod I 6 is hinged in frame by contact B5; Rotated around contact B5 by the flexible drivening rod I 6 of telescopic oil cylinder 2, cutterhead 1 is moved up and down, control the milling depth of cutterhead 1 road pavement.
Shock-absorbing spring 18 one end is affixed by pin I 13 and connecting rod III 19, and the other end is affixed by pin II 14 and connecting rod II 17, and main purpose is that the vibration produced when impact head 22 impacts ground is passed on bent axle 12.
The course of work of the present utility model is as follows:
When tractor 4 advances, hydraulic motor 9 works, dynamic crankshaft 12 is with to rotate by shaft coupling 10, bent axle 12 drives impact head 22 to do reciprocal moving up and down in pilot sleeve 16 by connecting rod III 19, pin I 13, shock-absorbing spring 18, pin II 14, connecting rod II 17 and pin III 20, continuous hammering cement pavement, make it produce crack, structure is damaged.Shock-absorbing spring 18 is that of avoiding the vibration produced when impact head 22 impacts cement pavement and passes on bent axle 12.Then telescopic oil cylinder 2 extends, and is with the cutterhead 1 on moving axis 21 to decline, carries out milling to cement pavement by connecting rod I 6.Due to the impact failure of impact head in early stage 22 pairs of cement pavements, make milling ratio be easier to carry out, controlled the milling depth of cutterhead 1 pair of cement pavement by the extensible canopy amount controlling telescopic oil cylinder 2.
