[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1 As shown, an asphalt paving device for highway pavement maintenance includes: a trolley 1 for movement; an asphalt drum 2 mounted on the trolley 1; a discharge mechanism 3 mounted on the asphalt drum 2, the discharge mechanism 3 including multiple discharge ports 31 penetrating the side wall of the asphalt drum 2; a mixing mechanism 4 located inside the asphalt drum 2; a spreading mechanism 5 communicating with the discharge ports 31, the spreading mechanism 5 including multiple discharge pipes 51; and a paving mechanism 6 located below the spreading mechanism 5.
[0023] The cart 1 is equipped with a handle and rollers. When maintaining the highway, the cart 1 moves the asphalt bucket 2 along the road surface to be maintained. The rollers enable rapid movement.
[0024] like Figure 2 As shown, the top of the asphalt bucket 2 is provided with a feeding channel 21, which is used to put the repair asphalt into the asphalt bucket 2. The bottom of the asphalt bucket 2 is provided with a heating plate 22. When there is asphalt material in the asphalt bucket 2, the heating plate 22 is in a heated state. The heating plate 22 keeps the asphalt bucket 2 at a temperature that allows the asphalt to flow, thereby preventing the asphalt from solidifying and causing the asphalt bucket 2 to become unusable.
[0025] The discharge mechanism 3 is used to control the flow of asphalt material from the asphalt drum 2. The discharge mechanism 3 also includes a blocking channel 32, multiple baffles 33, and fixing pins 34. The blocking channel 32 is located on the side wall of the asphalt drum 2. The blocking channel 32 is equivalent to a layer in the side wall of the asphalt drum 2. The width of the blocking channel 32 is the same as the width of the discharge port 31. The number of blocking channels 32 is the same as the number of discharge ports 31. The blocking channel 32 is connected to the bottom of the discharge port 31. The baffles 33 are slidably connected to the blocking channel 32. The baffles 33 can cut off the discharge port 31. When the baffles 33 enter the position of the discharge port 31, the baffles 33 prevent the asphalt material from flowing out of the asphalt drum 2. At this time, the asphalt paving can be suspended. The number of barriers 33 to be opened is selected according to the width of the road surface to be maintained. When the maintenance width is narrow, some barriers 33 are opened, and when the maintenance width is wide, all barriers 33 are opened. The width and quantity of asphalt material discharge are controlled by the number of barriers 33 opened, so that the width of the asphalt pavement is adapted to the width of the road surface to be repaired, while reducing the waste of asphalt material.
[0026] The asphalt drum 2 is equipped with vertical rods 23 at the top, the number of which is the same as the number of baffle plates 33. The vertical rods 23 are located behind the baffle plates 33. The top of the baffle plates 33 is provided with connecting holes, through which fixing pins 34 can pass. When it is necessary to open the discharge port 31, the baffle plates 33 are lifted. When the connecting holes are at the same height as the top of the vertical rods 23, the fixing pins 34 are passed through the vertical rods 23 and the connecting holes. At this time, the position of the baffle plates 33 can be fixed, ensuring stable discharge from the discharge port 31 below the baffle plates 33.
[0027] The mixing mechanism 4 includes a mixing blade 41 and a drive motor 42. The bottom of the mixing blade 41 is rotatably connected to the bottom of the asphalt tank 2, and the side of the mixing blade 41 is in contact with the inner wall of the asphalt tank 2. When the mixing blade 41 rotates, it can keep the asphalt fluid and facilitate the smooth discharge of asphalt. The output end of the drive motor 42 is fixed to the top of the mixing blade 41, and the fixed end of the drive motor 42 is fixed to the top of the asphalt tank 2. The fixed end of the drive motor 42 is located outside the asphalt tank 2 to reduce the impact of the high temperature of the asphalt tank 2 on the performance of the drive motor 42.
[0028] The fabric laying mechanism 5 also includes a feeder 52. The top of the feeder 52 is connected to the bottom of the discharge pipe 51. The asphalt material discharged from the discharge port 31 enters the discharge pipe 51 and then enters the feeder 52. The lower part of the feeder 52 is provided with multiple discharge ports 521. Each discharge pipe 51 corresponds to one discharge port 521. The discharge ports 521 are vertically downward. The asphalt entering the discharge port 521 is directly laid below the discharge port 521.
[0029] A baffle 522 is provided between the discharge ports 521. The baffle 522 prevents asphalt material from flowing into the adjacent discharge ports 31, ensuring the paving width of each discharge port 521 and reducing asphalt material waste. A switch plate is detachably connected to the discharge port 521. The switch plate is installed and removed through the gap at the top of the discharge port 521. When the discharge ports 521 are not fully used, the switch plate is placed above the unused switch plate to prevent residual asphalt from dripping from the discharge pipe 51.
[0030] The paving mechanism 6 is used to spread the asphalt material flowing from the feeder 52 onto the road surface to be repaired. The paving mechanism 6 includes a paving plate 61 and a sliding rod 62. The paving plate 61 is fixed to the bottom of the sliding rod 62, and the sliding rod 62 is slidably connected to the feeder 52. The sliding rod 62 changes the height of the paving plate 61 by sliding up and down, thereby ensuring that the asphalt material is at a preset paving height. The paving plate 61 is inclined upward, and the front end of the paving plate 61 can accommodate more asphalt material. As the trolley 1 moves forward, the asphalt material accumulates at the rear end of the paving plate 61, thereby ensuring that the final paving material can be completely filled.
[0031] A connecting rod 11 is provided on one side of the trolley 1. An adjusting screw 12 is screwed onto the connecting rod 11. The bottom of the adjusting screw 12 is rotatably connected to the end of the slide rod 62. The end of the slide rod 62 restricts the vertical movement of the connecting rod 11, allowing only relative rotation. When it is necessary to adjust the height of the paving slab 61, rotating the adjusting screw 12 causes vertical vertical movement between the adjusting screw 12 and the connecting rod 11, thereby causing the adjusting screw 12 to drive the slide rod 62 and the paving slab 61 to move vertically.
[0032] The trolley 1 is equipped with a storage battery 13, which is electrically connected to the heating plate 22 and the drive motor 42. The storage battery 13 provides power support for the heating plate 22 and the drive motor 42.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
