[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 6 It can be seen that a roughening machine for road and bridge construction includes a body 1, a cavity 2 is provided inside the body 1, a mounting plate 3 located below the cavity 2 is rotatably provided at the bottom of the body 1, a turntable 4 is provided in the cavity 2, a plurality of machine heads 5 are passed through the mounting plate 3, the top of the machine head 5 is in contact with the turntable 4, the bottom of the turntable 4 is a high and low wavy structure, a motor 6 is provided on the top of the body 1, the motor 6 drives the turntable 4 and the mounting plate 3 to rotate, the turntable 4 and the mounting plate 3 have different rotation speeds, and the rotation of the turntable 4 drives the machine head 5 to do reciprocating lifting and lowering motions.

[0020] When the utility model is used in a specific way,

[0021] On the construction section, the equipment is started, and the motor 6 drives the turntable 4 and the mounting plate 3 to rotate simultaneously. Due to the different rotation speeds of the mounting plate 3 and the turntable 4, a relative displacement occurs between the turntable 4 and the machine head 5. The wavy structure at the bottom of the turntable 4 causes the vertical position of the machine head 5 to change, and the machine head 5 makes a vertical reciprocating motion. The bottom of the machine head 5 roughens the road surface, thereby completing the roughening construction.

[0022] A plurality of wheels 7 are provided at the bottom of the machine body 1, and a push handle 8 is provided at the rear side of the machine body 1. The wheels 7 facilitate the transfer of the device, and the push handle 8 is used to operate the device.

[0023] A plurality of supporting wheels 9 are provided at the bottom of the machine body 1. When roughening the road surface, the supporting wheels 9 are in contact with the road surface, and the machine head 5 reciprocates vertically to roughen the road surface.

[0024] A gear 10 is meshed on the side of the mounting plate 3, and the gear 10 is connected to a transmission wheel 11 via a transmission shaft. The transmission wheel 11 is connected to the output shaft of the motor 6 via a belt 12. The motor 6 drives the mounting plate 3 to rotate through the transmission wheel 11 and the transmission shaft, so that the machine head 5 provided on the mounting plate 3 rotates, thereby realizing relative rotation with the turntable 4. The rotation of the machine head 5 can increase the roughening area of ​​the road surface and avoid construction blind spots.

[0025] The machine head 5 includes an upper end 13 and a lower end 14 which are telescopically connected. A ball 15 is provided on the top of the upper end 13. The top of the lower end 14 is inserted into the upper end 13 and is provided with a first spring 16. The first spring 16 pushes the lower end 14 downward. A second spring 17 is provided on the outside of the machine head 5. The second spring 17 pushes the upper end 13 upward.

[0026] The second spring 17 pushes the machine head 5 upward, so that the top ball 15 of the upper end 13 is always in contact with the bottom of the turntable 4, and cooperates with the wavy structure at the bottom of the turntable 4 to complete the vertical reciprocating motion of the machine head 5.

[0027] The telescopic structure between the upper end 13 and the lower end 14 is to cushion the impact when the lower end 14 contacts the road surface. The first spring 16 adopts a high-strength spring, which can not only transmit the force, but also be compressed when the load is too large to avoid damage to the nose 5.

[0028] Compared with the prior art, the utility model has the following beneficial effects: a turntable is used instead of a hydraulic cylinder to realize the lifting and lowering of the machine head, and the turntable and the machine head are rigidly connected to ensure the stability of the force during the roughening construction, while the retractable structure of the machine head can protect the machine head and prevent the machine head from being damaged due to excessive load.
