DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0021] like Figure 1 to Figure 5As shown, an asphalt pavement corner compacting device includes a box body 1, a support member and an adjusting rod 2; the box body 1 is a hollow rectangular parallelepiped with an opening at the lower end blocked by a bottom plate, the front and rear ends of the outer bottom of the box body 1 are connected with vertical plates 3, the vertical plates 3 are vertically arranged rectangular plates, and a pressure roller 4 with a lower end lower than the vertical plates 3 is rotatably connected between the two vertical plates 3; the left and right sides of the box body 1 are provided with support members, the two support members are in a left-right symmetrical state, and the support member on the left side includes a rotating rod 5 and a supporting rod 6, the rotating rod 5 is a round rod body, the rotating rod 5 is located in the left part of the box body 1, the front end of the rotating rod 5 passes through, and is rotatably connected to the box body via a bearing 7. The front side plate of the box body 1, the rear end of the rotating rod 5 passes through and is rotatably connected to the rear side plate of the box body 1 through the bearing 2 8. A gear 9 is fixedly arranged on the outer surface of the rotating rod 5 in the box body 1. The front and rear ends of the rotating rod 5 are fixedly connected with a support rod 6 with the lower end tilted to the left. The support rod 6 is a rectangular rod, and the two support rods 6 are symmetrical front and back. A roller 10 is provided at the lower end of the support rod 6; an adjusting rod 2 is provided between the gears 9 on the two supports, and the adjusting rod 2 is a rectangular rod body. The left and right sides of the adjusting rod 2 are provided with teeth 11 meshing with the gear 9 on the same side, and an adjusting member for driving the adjusting rod 2 to move upward or downward is provided on the box body 1.

[0022] A U-shaped groove 12 is recessed on the bottom surface of each support rod 6 . The U-shaped groove 12 passes through the left and right side surfaces of the support rod 6 . A roller 10 is rotatably connected between the front and rear side surfaces of the U-shaped groove 12 .

[0023] The adjusting member includes a limit rod 13 and a screw rod 14. The left and right parts of the adjusting rod 2 are both provided with a limit rod 13. The limit rod 13 is a round rod body. The upper end of the limit rod 13 is fixedly connected to the top plate of the box body 1, and the lower end passes through the adjusting rod 2 to connect to the bottom plate of the box body 1. The screw rod 14 is threadedly connected to the adjusting rod 2, the lower end of the screw rod 14 is rotatably connected to the bottom plate of the box body 1, and the upper end movably passes through the top plate of the box body 1.

[0024] The adjusting rod 2 is provided with a threaded hole 15 corresponding to the screw rod 14 , and the upper end of the screw rod 14 is connected with a rotating plate 16 .

[0025] The adjusting rod 2 is provided with a through hole 17 for the limiting rod 13 to pass through and to slidably contact the limiting rod 13 . The length of the adjusting rod 2 is smaller than the distance between the upper and lower inner sides of the box body 1 .

[0026] A connecting rod 18 is rotatably connected between the two supporting rods 6 of the supporting member on the left side, and a connecting plate 19 is connected to the connecting rod 18. The connecting plate 19 is used to connect a mechanical device that drags the roller 10 and the pressure roller 4 to roll.

[0027] When in use, the rotating plate 16 drives the screw rod 14 to rotate. Since the adjusting rod 2 is limited by the limiting rod 13 and can only move upward or downward, when the screw rod 14 rotates, the adjusting rod 2 is driven to move upward. When the adjusting rod 2 moves upward, the teeth 11 on the left side of the adjusting rod 2 engage the gear 9 on the left support and rotate counterclockwise (the gear 9 on the left support rotates counterclockwise for Figure 2 The rotating rod 5 on the left support rotates counterclockwise with the gear 9 on the left, so that the lower ends of the two support rods 6 on the left support move rightward, and the teeth 11 on the right side of the adjusting rod 2 engage the gear 9 on the right support and rotate clockwise (the gear 9 on the right support rotates clockwise for Figure 2 The rotating rod 5 on the right support member rotates clockwise with the gear 9 on the right side, so that the lower ends of the two support rods 6 on the right support member move to the left, and the lower ends of the two support rods 6 on the left support member move relative to the lower ends of the two support rods 6 on the right side, thereby causing the box body 1 to drive the pressing roller 4 to move upward through the vertical plate 3. Since the rollers 10 at the lower ends of the two support rods 6 on the left support member only roll and keep the height unchanged during the movement to the right, and the rollers 10 at the lower ends of the two support rods 6 on the right support member only roll and keep the height unchanged during the movement to the left, , rotating the screw 14 can adjust the height difference between the high-pressure roller 4 and the roller 10; similarly, by rotating the screw 14 in the opposite direction, the lower ends of the two support rods 6 on the left support member and the lower ends of the two support rods 6 on the right side move away from each other, and rotating the screw 14 in the opposite direction can adjust the height difference between the low-pressure roller 4 and the roller 10; therefore, the utility model can adjust the height of the pressure roller 4 according to the thickness of the asphalt pavement corners that need to be compacted. After the adjustment is completed, the connecting plate 19 is used to connect the mechanical equipment used to drag the utility model, driving the roller 10 and the pressure roller 4 to roll synchronously, and the pressure roller can compact the asphalt pavement corners.
