DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0021] A concrete pavement repair machine, such as Figure 1-Figure 3 As shown, it includes a frame 1, wheels 2 and handles 3. The frame 1 is provided with wheels 2 at the bottom, and the handle 3 is fixedly connected to one end of the frame 1. It also includes a mixing tank 4, mixing blades 5, a first motor 6, a valve 8, a feed pipe 9, a screed plate 10 and a slide bar 12. The mixing tank 4 is fixedly connected to the frame 1, and the first motor 6 is fixed to the top surface of the mixing tank 4 through a bracket. The mixing blade 5 is located in the mixing tank 4, and the first motor 6 provides power for the mixing blade 5. The bottom of the mixing tank 4 is connected with a feed pipe 9, and the feed pipe 9 is provided with a valve 8. The slide bar 12 is symmetrically fixed to the end of the frame 1, and the screed plate 10 is slidably connected to the slide bar 12.

[0022] like Figure 1 and Figure 3 As shown, a control rod 7 is also included, and the control rod 7 is vertically fixed to the valve 8.

[0023] like Figure 3 and Figure 4 As shown, a fixing pin 11 is also included. The fixing pin 11 is slidably connected to the screed plate 10 , and the fixing pin 11 can be snap-connected with the frame 1 .

[0024] like Figure 1 and Figure 5 As shown, it also includes a water tank 13 and a nozzle 14. The water tank 13 is fixed to the frame 1, and the water tank 13 is connected to the rotating nozzle 14.

[0025] like Figure 1 and Figure 6 As shown, it also includes a second motor 15, a missing gear 16, a turntable 17, a protruding rod 18 and a brush 19. The second motor 15 is fixed to the frame 1 by bolts. The output shaft of the second motor 15 is connected to a transmission rod through a coupling. Two missing gears 16 are connected to the transmission rod through a key. The teeth of the two missing gears 16 are centrally symmetrically arranged. The turntable 17 is rotatably connected to the frame 1. A brush 19 is fixed to the bottom of the turntable 17. The end surface of the turntable 17 is evenly provided with protruding rods 18. The missing gears 16 can be snapped together with the protruding rods 18.

[0026] The handle 3 is pushed to drive the frame 1 to move forward, and the concrete is introduced into the mixing tank 4. Then, the first motor 6 is turned on to drive the mixing blade 5 to rotate. The mixing blade 5 can maintain the fluidity of the concrete. The second motor 15 is turned on to drive the missing gear 16 to rotate. Since the tooth angle of the two missing gears 16 is 180 degrees, the two missing gears 16 will contact the protruding rods 18 of the turntable 17 one by one, thereby driving the turntable 17 to reciprocate. The turntable 17 will drive the brush 19 to swing back and forth, and the brush 19 can remove debris on the forward path of the frame 1. Remove it to improve the cleanliness of the road surface, and then the nozzle 14 sprays the water in the water tank 13 to further clean the road surface, push the frame 1 to the cracks in the road surface, and then by rotating the control lever 7, the valve 8 can be driven to open, and the concrete will be introduced into the cracks in the road surface from the discharge pipe 9. After the concrete is introduced, the control lever 7 is rotated to close the valve 8, and then the screed plate 10 is slid downward, and the screed plate 10 is limited and fixed by the fixing pin 11, and then the frame 1 is pushed forward, and the screed plate 10 can scrape the surface of the concrete in the cracks in the road surface.
