Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction equipment technology, and more specifically, to an asphalt cold patching material laying device for road construction. Background Technology
[0002] In road construction, cold asphalt patching is widely used for repairing road defects such as potholes and cracks due to its advantages of not requiring heating and being able to be repaired at any time. Currently, common cold asphalt patching laying devices on the market mainly focus on the transportation and paving of cold patching. However, existing laying devices often lack the function of compacting cold patching. In actual construction, after the cold patching is laid, the compaction work often needs to be carried out separately by operators using other tools such as road rollers and tampers. This separate operation mode not only makes the construction process cumbersome and increases the workload of operators, but also greatly reduces construction efficiency and prolongs the road repair period. At the same time, since the laying and compaction of cold patching cannot be carried out simultaneously, the cold patching may be affected by external factors such as vehicle rolling while waiting for compaction, which will affect the compaction effect and the quality of road repair. In addition, the additional compaction tools also increase the cost of construction equipment and management. Therefore, it is necessary to improve the system. Utility Model Content

Due to the design of the limiting groove 2, the movement of the moving plate 8 will be limited. At this time, the moving plate 8 will move up and down repeatedly along the interior of the limiting groove 2 under the drive of the extrusion shaft 7. At this time, the moving plate 8 will drive the compaction plate 10 to move up and down repeatedly through the column 9. When the compaction plate 10 moves downward, it will compact the asphalt cold patch material.

[0043] Due to the design of the material hopper 24, it can be used as a container for storing cold replenishment materials.
[0044] Among them, a support plate 25 is fixedly installed on the outer surface of the material barrel 24, a power motor 26 is fixedly installed on the outer surface of the support plate 25, a first long shaft 27 is fixedly sleeved at the output end of the power motor 26, the outer surface of the first long shaft 27 is movably sleeved with the inside of the material barrel 24, and a stirring blade 28 is fixedly sleeved on the outer surface of the first long shaft 27.
[0045] When the power motor 26 is running, the first long shaft 27 will drive the stirring blade 28 to rotate. When the stirring blade 28 rotates, it will stir the cold replenishment material inside the material bucket 24, so that the cold replenishment material always remains in a loose state.
[0046] The bottom of the material barrel 24 is movably fitted with a second long shaft 29, the front end of the second long shaft 29 is fixedly fitted with a third toothed pulley 30, and the outer surface of the second long shaft 29 is fixedly fitted with a rotating plate 31, the outer surface of the rotating plate 31 is in contact with the bottom of the material barrel 24.
[0047] When the third toothed pulley 30 rotates, it will drive the rotating plate 31 to rotate through the second long shaft 29. Due to the design of the rotating plate 31, the cold replenishment material inside the material barrel 24 can be fed evenly and stably.
[0048] The front end of the first long shaft 27 is fixedly sleeved with a fourth toothed pulley 32, which is connected to the third toothed pulley 30 via a second toothed belt 33.
[0049] When the first long shaft 27 rotates, the fourth toothed pulley 32 will rotate, and at this time the fourth toothed pulley 32 will drive the third toothed pulley 30 to rotate through the second toothed belt 33.
[0050] The outer surface of the material barrel 24 is fixedly equipped with a second protective shell 22.

[0051] Due to the design of the second protective shell 22, it can provide good protection for the fourth toothed pulley 32, the second toothed belt 33 and the third toothed pulley 30.
[0052] Working principle and usage process of this utility model:
[0053] When the operator needs to repair the road surface, the operator moves the entire device to the location requiring repair, aligning the bottom of the material bucket 24 with the top of the damaged road surface. The operator then starts the power motor 26. At this time, the first long shaft 27 simultaneously drives the mixing blade 28 and the fourth toothed pulley 32 to rotate. When the mixing blade 28 rotates, it can stir the cold patch material inside the material bucket 24, thereby maintaining the fluidity of the cold patch material inside the material bucket 24 for subsequent feeding. When the fourth toothed pulley 32 rotates, it drives the third toothed pulley 30 to rotate through the second toothed belt 33. At this time, the third toothed pulley 30 drives the rotating plate 31 to rotate through the second long shaft 29. Due to the design of the rotating plate 31, the cold patch material inside the material bucket 24 can fall evenly to the damaged road surface, thereby realizing the function of automatic, smooth and uniform feeding of cold patch material.
[0054] Next, the operator starts the drive motor 13. At this time, the rotating shaft 14 will drive the second toothed pulley 15 to rotate. The second toothed pulley 15 will drive the first toothed pulley 5 to rotate through the first toothed belt 16. Since the outer surface of the second toothed pulley 15 is meshed with the outer surface of the gear 17, when the second toothed pulley 15 rotates, it will drive the gear 17 to rotate. The gear 17 will drive the roller 19 to rotate through the round shaft 18. When the roller 19 rotates, it will drive the entire device to move forward at a uniform speed, so that the cold patch material can be automatically and evenly laid on the road damage.
[0055] When the first toothed pulley 5 rotates, it drives the rotating shaft 4 to rotate inside the support frame 3. At this time, the rotating shaft 4 drives the two extrusion shafts 7 to rotate through the two rotating blocks 6. The outer surfaces of the two extrusion shafts 7 will squeeze and push the interior of the two moving plates 8 during rotation, causing the two moving plates 8 to move. Since the outer surfaces of the two moving plates 8 are slidably connected to the interior of the two limiting grooves 2, the movement of the two moving plates 8 will be limited by the interior of the two limiting grooves 2, so that the two moving plates 8 can only move up and down. Therefore, the two moving plates 8 will drive the compaction plate 10 to move up and down repeatedly through the two columns 9. When the compaction plate 10 moves downward and comes into contact with the cold patch material, it will compact the cold patch material. Since the whole device is in a state of continuous forward movement, the compaction plate 10 can automatically compact the laid cold patch material, thereby realizing the automatic compaction function of asphalt cold patch material.
