Further, described freewheel clutch outer ring is provided with reduction gearing, described reduction gearing and the engagement of driving tooth axle, and described driving tooth axle is connected with described motor.
Further again, the endoporus place, rear end of described active impact block is installed with impact spring, described impact spring is supported by the front end face that impacts reduction gearing, and described impact reduction gearing is installed in the rear end of described impacting shaft, and described impacting shaft head offers helicla flute and laying steel ball.
Also further, described impact reduction gearing meshes with impacting driving gear, and described impact driving gear is fixed on described driving tooth shaft rear end.
The utility model in use, rotatablely moving by the driving tooth axle and impacting driving gear of motor drives main shaft and impacting shaft rotation respectively, the main shaft drive milling cutter cutting concrete of rotation, and the rotation of impacting shaft makes active impact block generation impulsive force hit driven impact block and make main shaft drive milling cutter impact concrete finished surface, make its pulverizing while cutting.
The beneficial effects of the utility model are: loaded beater mechanism on the main shaft, made milling cutter produce impact, vibration and two motor patterns of milling, it is broken to impel concrete surface to shake under impact force action, has reduced cutting resistance, has improved working (machining) efficiency greatly.

(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
See figures.1.and.2, a kind of concrete slotting attachment, comprise motor (1), described motor (1) is connected with backgear case lid (2), described backgear case lid (2) is connected with gear-box (3), described gear-box (3) is connected with front gear case lid (4), in described gear-box (3) and the described front gear case lid (4) main shaft (5) is installed, the front end of described main shaft (5) stretches out and milling cutter (6) is installed from described front gear case lid (4), the rear end of described main shaft (5) is stretched out and is connected with driven impact block (7) from described gear-box (3), the axle center of described driven impact block (7) is connecting impacting shaft (8), described impacting shaft (8) is gone up suit and initiatively impact block (9), described active impact block (9) and described driven impact block (7) engagement, the stage casing rigidity of described main shaft (5) is installed with freewheel clutch ratchet (10), described freewheel clutch ratchet (10) is connected with ratchet (11), described ratchet (11) is connected with freewheel clutch outer ring (13) by pin (12), and described freewheel clutch outer ring (13) is installed in the stage casing of described main shaft (5).
Described freewheel clutch outer ring (13) is provided with reduction gearing (14), described reduction gearing (14) and driving tooth axle (15) engagement, and described driving tooth axle (15) is connected with described motor (1).
The endoporus place, rear end of described active impact block (9) is installed with impact spring (16), described impact spring (16) is supported by the front end face that impacts reduction gearing (17), described impact reduction gearing (17) is installed in the rear end of described impacting shaft (8), and the head of described impacting shaft (8) offers helicla flute (18) and laying steel ball (19).
Described impact reduction gearing (17) meshes with impacting driving gear (20), and described impact driving gear (20) is fixed on described driving tooth axle (15) rear end.
Connect power supply, motor (1) rotation, drive driving tooth axle (15) rotation, driving tooth axle (15) divides two-way to make reduction gearing (14) and impacts reduction gearing (17) rotation synchronously, because the speed ratio difference of setting, the rotating speed that impacts reduction gearing (17) is higher than reduction gearing (14) several times, by impacting shaft (8), initiatively the impact force action of impact block (9) and impact spring (16) and steel ball (19) generation is to driven impact block (7) and main shaft (5), driven impact block (7) and main shaft (5) have obtained to be higher than the frequency of impact of the rotating speed several times that main shaft (5) passes over from reduction gearing (14), main shaft (5) are had be higher than the impact rotating energy of himself rotating speed several times.
