Driving device comprises large pulley 20, small pulley 18, belt 19, front axle 31, first gear 12, second gear 13, motor 21 connects large pulley 20, passes between small pulley 18 and large pulley 20 The belt 19 is connected, the large pulley 20 is arranged on the side of the lifting platform 7, the small pulley 18 is connected to the front axle 31, the front axle 31 stretches into the outer cover 30, the first gear 12 and the second gear 13 are all arranged on the front axle On 31; The 3rd gear 14 coaxially connects blade 15, and this axle is fixed on the lower end of blade elevating lever; The 4th gear 16 coaxially connects cleaning brush 17, and this axle is fixed on the lower end of cleaning brush elevating lever. The motor 21 and the driving device provide power for the blade 15 and the seam cleaning brush 17 .

The seam filling mechanism is composed of a controller 8, a burner 23, an insulating tank 1, a seam filling gun 24, a leveler 9, an agitator and its supporting micro-motor 22, the agitator and its supporting micro-motor 22 are located at the upper part, and the agitator extends Into the insulation tank 1, the agitator is a paddle agitator, the paddle has two blades, and is a two-blade stirring structure without baffles. Asphalt material for filling cracks is housed in the insulation tank 1, as shown in Figure 4, a burner 23 is arranged at the lower end of the insulation tank 1, and the burner 23 below performs heating and heat preservation work. The burner 23 is connected to the controller 8, one end of the caulking gun 24 is connected to the insulation tank 1, the other end of the caulking gun 24 points to the ground, the controller 8 controls the heating condition of the burner 23 according to the road surface demand, and then the asphalt material is sprayed out by the caulking gun 24 To perform joint filling operation, the present invention adopts a drag-type asphalt sealant to heat the insulation tank 1 and the asphalt discharge pump, and the controller 8 is set to be operated by buttons.

As shown in Figure 5, the scraper 9 is arranged below the frame 28, and the scraper 9 is fixedly installed at the bottom of the device, in the same straight line as the seam cleaning brush 17. Use the leveler 9 to level the surface after filling the joints. In the same straight line with the seam cleaning brush 17, the height of the scraper 9 can be adjusted according to the form of the seam filling surface. The main body of the scraper 9 is located at the bottom, and is connected with two clamping plates by bolts.

The construction worker pulls the trolley to the road crack, slowly turns the blade handwheel 11 to make the third gear 14 contact with the second tooth 13 wheel, and then continues to rotate the blade handwheel 11 to the dead point position. At this time, the third gear 14 and the second tooth The gear 13 is fully meshed, that is, the central axis coincides, and the blade hand wheel 11 and the lifting platform 7 are temporarily fixed by threads. Then start the engine to make the large pulley 20 rotate and drive the small pulley 18 to rotate through the belt transmission (the small pulley 18, the second gear 13, the first gear 12 are coaxial, all are positioned on the front axle 31, the 3rd gear 14 and the blade 15 coaxial, located on the rear axle), the generated power is transmitted to the second gear 13 via the front axle 31 from the first gear 12 to the third gear 14 on the rear axle and then to the blade 15 successively, so that the blade 15 starts to rotate Then turn the main hand wheel 2 to make the lifting platform 7 gradually descend until the blade 15 contacts the ground so as to realize the slotting process (during this process, the vibration is greatly reduced due to the existence of the bellows and the spring between the lifting platform 7 and the outer cover 30). When slotting, construction workers adjust the guide rod 6 (as shown in Figure 6) to the position of the left block guide block, so that the guide rod 6 and the blade 15 are in a straight line.

The seam filling process and the seam cleaning process are carried out at the same time. When preparing to clean the seam, adjust the trolley so that the seam cleaning brush 17 and the guide rod 6 are located in the gap to be cleaned (fix the guide rod 6 at the guide block of the right block), Turn on the vacuum cleaner 4, and the construction worker pulls the handle 5 to drive the trolley back. In the process of retreating, the gravel produced by the slotting will fall into the groove of the slabstone, and the dust will enter the vacuum cleaner 4 through the outer cover 30 and through the suction hose 3 . Start the micro-motor 22 while cleaning the seam, as shown in Figure 4, the power switch of the burner is opened, and the heating work is carried out. When the oil temperature of the burner reaches the set value, start the stirring motor for stirring. After the sealing compound in the hot-melt kettle is fully melted, first open the valve of the discharge port, and then start the asphalt pump until the nozzle is discharged. After the material is evenly discharged, the construction can be carried out, and the sealant is poured into the crack.

During work, construction workers adjust the trolley so that the guide rods 6 are all located in the gaps to be cleaned. The construction personnel pulls the handle 5 to drive the dolly to retreat. The seam filling gun 24 evenly discharges the material. In the process, both the cleaning of the seam and the seam filling operation are completed, which greatly saves the workload.

After the operation is completed, the operator can determine whether secondary filling is required by observing the quality of the joint filling. At the same time, in the process of filling the joints, use the leveler 9 (as shown in Figure 5) to level the surface after filling the joints, and drag to form a seal with a certain width and thickness on both sides of the crack. After it solidifies, the highway will be opened, and the specific opening time for traffic can be flexibly controlled according to the temperature situation.

The traditional seam cleaning and slotting process will produce a lot of smoke and dust. To solve the smoke and dust problem, the present invention adopts the dust suction principle to absorb and filter out a large amount of smoke and dust generated in the process of slotting and slot cleaning. The seam mechanism is designed as an integral device, which not only saves cost and manpower during construction, but also does not cause environmental pollution.

The seam clearing, slotting and seam expansion process of the present invention is completed through the operation of the hand wheel and the lifting table 7, and the operation is simple, safe and reliable. Simultaneously, the improved design of the guide rod 6 not only saves space, but also facilitates the operation. The slotting, cleaning and filling operations required by the original slotting and filling technology are realized through the same device, which can not only maximize the advantages of low cost, quick construction and good construction effect of the slotting and filling technology, but also ensure Workers do not need to carry and replace various equipment to complete each process, so that the device is truly lightweight. At the same time, the design of the integrated device also saves the cost of slotting and joint filling construction.
