By setting the tamping plate 805 and starting the fourth motor 801, the tamping plate 805 is driven to move up and down to further compact the compacted road surface.

使用时，通过将螺旋加热管205、第一电机202、第二电机401、第三电机604、第四电机801和第五电机9与市政电源相连接，将牵引架13与外界驱动车辆相连接，通过将沥青通过装料口203倒入保温罐201的内部，启动第五电机9，通过设置清扫刷902，便于对路面上的碎石灰尘进行清扫，提高沥青的附着能力，通过启动螺旋加热管205，对保温罐201内部的沥青进行保温加热，通过启动第一电机202，通过搅拌叶204对保温罐201内部的沥青进行搅拌，防止保温罐201内部的沥青凝固，通过启动，通过启动第二电机401，带动凸轮402进行转动，通过凸轮402的凸起挤压顶板405下降，当凸轮402的凸起竖直向上时，通过第一弹簧404的复位带动活动杆403的上升，从而使活动杆403做上下的往复运动，从而通过压板301，使抽取箱3的内部形成负压从而抽取保温罐201内部的沥青，通过沥青排管302使得沥青能够均匀的排放到公路上，通过铺平轮11对排放到公路上的沥青进行铺平，根据所铺设沥青的厚度，启动第三电机604，通过齿轮602的转动，来调节调节杆606的下降调节碾压轮10对压实沥青的压力，从而调节所铺设沥青的厚度，通过启动第四电机801，带动夯实板805上下运动对压实的路面进行进一步的夯实，通过设置固定杆503和滑杆502，防止夯实箱8下降的过程的晃动。When in use, by connecting the spiral heating pipe 205, the first motor 202, the second motor 401, the third motor 604, the fourth motor 801 and the fifth motor 9 with the municipal power supply, the traction frame 13 is connected with the external driving vehicle , by pouring the asphalt into the interior of the heat preservation tank 201 through the charging port 203, starting the fifth motor 9, and setting the cleaning brush 902, it is convenient to clean the gravel dust on the road surface, improve the adhesion ability of the asphalt, and by starting the spiral heating The pipe 205 is used to heat the asphalt inside the heat preservation tank 201. By starting the first motor 202, the asphalt inside the heat preservation tank 201 is stirred by the stirring blade 204 to prevent the asphalt in the heat preservation tank 201 from solidifying. The second motor 401 drives the cam 402 to rotate, and the top plate 405 is pressed down by the protrusion of the cam 402. When the protrusion of the cam 402 is vertically upward, the reset of the first spring 404 drives the movable rod 403 to rise, thereby making the movable rod 403 move upward. The rod 403 reciprocates up and down, so that through the pressing plate 301, a negative pressure is formed inside the extraction box 3 to extract the asphalt inside the heat preservation tank 201, and the asphalt can be uniformly discharged to the road through the asphalt pipe 302. 11. Pave the asphalt discharged to the road, start the third motor 604 according to the thickness of the laid asphalt, and adjust the downward adjustment of the adjustment rod 606 through the rotation of the gear 602 to adjust the pressure of the roller 10 to compact the asphalt, Thus, the thickness of the laid asphalt is adjusted, and the fourth motor 801 is activated to drive the compaction plate 805 to move up and down to further compact the compacted road surface. By setting the fixing rod 503 and the sliding rod 502, the shaking of the compaction box 8 is prevented during the descending process. .
