DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, a road maintenance pavement grouting device includes a frame 1, which drives other components to move along the crack direction, and also includes: an asphalt box 2, which is mounted on the frame 1; a diversion mechanism 3, which is connected to the asphalt box 2; a width limiting component 4, which is in contact with the side wall of the road crack, and asphalt enters the crack through the width limiting component 4; a stirring mechanism 5, which stirs the asphalt of the diversion mechanism 3; a lifting mechanism 6, which is connected to the stirring mechanism 5, and the lifting mechanism 6 drives the stirring mechanism 5 to move vertically.

[0024] The diversion mechanism 3 includes a drainage pipe 31, a receiving hopper 32 and a diversion groove 33. The drainage pipe 31 connects the asphalt tank 2 and the receiving hopper 32. A valve 311 is provided on the drainage pipe 31. The valve 311 is opened and closed to control whether the asphalt can pass through the drainage pipe 31 and enter the receiving hopper 32. The receiving hopper 32 is an inverted cone. The upper area of ​​the receiving hopper 32 is larger than the bottom area. The bottom of the receiving hopper 32 is fixedly connected to the diversion groove 33. The asphalt flows from the bottom of the receiving hopper 32 into the diversion groove 33. The diversion groove 33 is inclined toward the direction of the cracks in the road. The asphalt flows along the diversion groove 33 toward the cracks. The state of the asphalt can be observed when the asphalt passes through the diversion groove 33. If the asphalt has poor fluidity or condensation, it can be discovered and adjusted in time.

[0025] Two support wheels 331 are provided at the bottom of the guide groove 33. The distance between the support wheels 331 is greater than the width of the crack. The support wheels 331 assist the movement of the guide groove 33. At the same time, the support wheels 331 can enhance the bearing capacity of the guide groove 33 and make the guide groove 33 more stable.

[0026] like Figure 2As shown, the width limiting component 4 is located at the front end of the guide groove 33, and the asphalt flows into the crack through the width limiting component 4. The width limiting component 4 prevents the asphalt from flowing out. The width limiting component 4 includes a track rod 41, two movable plates 42, a spring cavity 43 and a tension spring 44. The front end opening of the guide groove 33 shrinks toward the middle. The track rod 41 is fixed to the top of the front end of the guide groove 33. The bottom of the track rod 41 has an inner concave to form a slideway. The top of the movable plate 42 is slidably connected to the track rod 41. The spring cavity 43 is arranged on both sides of the track rod 41. The tension spring 44 connects the movable plate 42. The top and spring cavity 43, when the tension spring 44 is in a normal state, the two movable plates 42 are at the two ends of the track rod 41, and a triangular pyramid block 421 is provided at the bottom of the movable plate 42. Before grouting, the two movable plates 42 are pulled toward the middle, and the bottom of the triangular pyramid block 421 is placed into the crack. Under the tension of the tension spring 44, the two movable plates 42 move to both sides, and the side walls of the movable plates 42 fit into the crack, thus ensuring that all the asphalt can flow into the crack, reducing the waste of asphalt and preventing the asphalt from being scattered in other places on the road and affecting the appearance.

[0027] A guard plate 422 is fixedly connected to the side wall of the movable plate 42. The guard plate 422 is perpendicular to the movable plate 42. The bottom of the guard plate 422 is located above the triangular pyramid block 421. The guard plate 422 will not enter the crack. When the movable plate 42 moves toward the middle of the guide groove 33, the guard plate 422 covers the gap between the movable plate 42 and the side wall of the guide groove 33, so that the asphalt can only flow out from between the two movable plates 42.

[0028] like Figure 3 As shown, the stirring mechanism 5 includes a stirring head 51, a transmission rod 52 and a motor 53. The transmission rod 52 connects the top of the stirring head 51 and the output end of the motor 53. After the motor 53 is started, the motor 53 drives the transmission rod 52 and the stirring head 51 to rotate together. The asphalt flowing into the receiving hopper 32 is stirred by the rotation of the stirring head 51, so that the bubbles in the asphalt are discharged, reducing the probability of bubbles being wrapped in the cracked asphalt, improving the quality of the grouting, and at the same time increasing the fluidity of the asphalt through stirring, so that the asphalt can quickly enter the cracks and increase the efficiency of the grouting.

[0029] The outer diameters at both ends of the stirring head 51 are smaller than the outer diameter in the middle of the stirring head 51. A number of stirring blades are fixedly connected to the side walls of the stirring head 51. The stirring head 51 protruding in the middle prevents the asphalt from moving toward the receiving hopper 32. When the stirring head 51 moves downward, the asphalt discharge speed slows down. When the stirring head 51 moves upward, the asphalt discharge speeds up. The position of the stirring head 51 is controlled by the lifting mechanism 6.

[0030] The lifting mechanism 6 includes a track plate 61, a lifting plate 62, a rotating shaft plate 63 and a threaded rod 64. The track plate 61 is welded to the side wall of the asphalt box 2, the track plate 61 is vertically arranged, the lifting plate 62 is slidably connected to the lifting plate 62, and a motor 53 is connected to the bottom of the lifting plate 62. The lifting plate 62 drives the motor 53 to move, and further drives the stirring head 51 to move up and down. The rotating shaft plate 63 is welded to the side wall of the track plate 61, the threaded rod 64 penetrates the lifting plate 62 and is rotatably connected to the rotating shaft plate 63, the threaded rod 64 is screwed to the lifting plate 62, and a handle 641 is provided on the top of the threaded rod 64, and the threaded rod 64 is rotated by the handle 641.

[0031] Two slide rails 611 are protruding from the side wall of the track plate 61, and two recesses are provided at the rear end of the lifting plate 62, which are slidably connected to the slide rails 611. When the stirring head 51 needs to be raised or lowered, the handle 641 is turned to drive the lifting plate 62 to move, and the slide rails 611 limit the left and right rotation of the grooves, further limiting the lifting plate 62 to only vertical movement.

[0032] A connecting rod 7 is passed through the bottom of the track plate 61, one end of the connecting rod 7 is fixedly connected to the bottom of the guide groove 33, and the other end of the connecting rod 7 is provided with a smoothing wheel 8. After the asphalt is filled, the asphalt is flattened with the road surface by rolling the smoothing wheel 8.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
