Detailed Embodiment
[0019] The present utility model will be further explained and described below with reference to the drawings:
[0020] Embodiment 1. An auxiliary device for paving an old cement road surface in a municipal road, comprising a bottom rod 1, a positioning sleeve 5 and a handle 6. A positioning sleeve 5 is vertically arranged above the left end of the bottom rod 1. A handle 6 is arranged inside the positioning sleeve 5. A blanking hole 2 is arranged on the bottom rod 1 on the right side of the positioning sleeve 5. A first support rod 3 is arranged on the right side of the blanking hole 2. A V-shaped scraping plate 4 is arranged at the bottom of the first support rod 3. A bracket 8 is sleeved on the right end of the bottom rod 1. Triangular brackets 9 are respectively arranged on both sides of the bracket 8. A storage rack 10 is rotatably connected between the two triangular brackets 9. A pouring bucket A is arranged inside the storage rack 10.
[0021] The handle 6 is distributed in a T shape. The handle 6 is inserted into the positioning sleeve 5 and is fixedly connected with the positioning sleeve 5 through bolts.
[0022] A jack is dug on the bottom rod 1 on the right side of the blanking hole 2. A positioning sleeve is arranged above the jack. The upper end of the first support rod 3 penetrates through the jack and the positioning sleeve and is fixed by a matching bolt.
[0023] The middle part of the bracket 8 is sleeved on the bottom rod 1 and is fixed by a matching bolt. Rolling wheels 7 are respectively arranged at the bottoms of both ends of the bracket 8 and at the bottom of the left end of the bottom rod 1.
[0024] Shaft rods are fixedly connected to both ends of the storage rack 10. The shaft rods are rotatably connected with the triangular brackets 9. Tightening bolts 14 are arranged outside the triangular brackets 9.
[0025] A second support rod 11 is arranged on the right side of the top of the storage rack 10. A displacement sleeve 12 is sleeved on the second support rod 11.
