Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0036] In one embodiment of the utility model, an integrated synchronous chip seal automated construction device is provided. Figure 1 , Figure 2 As shown, the vehicle body comprises a vehicle body, an aggregate placing device and an asphalt storage device 3 are installed on the upper part of the vehicle body, and an asphalt spraying device 12 and a gravel spreading device 13 are installed on the lower part of the vehicle body. Figure 3 As shown, wheels for movement are also installed at the bottom of the vehicle body, and a power supply device is arranged at the top of the asphalt storage device 3, which is used to connect with the asphalt storage device 3, the asphalt spraying device 12 and the gravel spreading device 13 to supply power to them. The asphalt spraying device 12 is connected with the asphalt storage device 3 to sprinkle the asphalt in the asphalt storage device 3, and the gravel spreading device 13 is used to sprinkle the stone in the aggregate delivery device; in addition, the asphalt storage device 3 and the aggregate delivery device are separately arranged (not connected), and the two do not affect each other; the rolling wheel 14 is connected to the rear of the vehicle body, and the rolling wheel 14 is used to compact the stone spilled by the gravel spreading device 13.

[0037] The asphalt spraying device 12 uses a plurality of asphalt spraying heads, such as Figure 6 As shown; the main body of the chip seal construction device trolley is a rectangular plate, with universal wheels 11 installed at the lower part, there are four universal wheels 11, and they are installed at the lower part of the four corners of the trolley body; the longitudinal end of the chip seal construction device is equipped with a mobile handle 17.

[0038] The utility model integrates the spraying and compacting of asphalt and crushed stone into one body, and compared with the existing large-scale construction equipment, it has the advantages of small size, flexible operation and low cost.

[0039] Example 1

[0040] An integrated synchronous chip seal automated construction device includes a storage system and a spreading and rolling system, wherein:

[0041] The storage system includes an asphalt storage device 3, which is provided with a heating facility and a temperature monitoring facility. Specifically, the heating facility adopts a heating resistor, and the temperature monitoring facility adopts an asphalt temperature controller 9. The asphalt temperature controller 9 is installed on the outer wall of the asphalt storage device 3. The asphalt temperature controller 9 can read the asphalt temperature and set it to a certain temperature to keep the asphalt warm; the aggregate delivery device adopts a plurality of independent aggregate delivery troughs 1, and a sliding paddle 2 is provided inside the aggregate delivery trough 1. The sliding paddle 2 and the aggregate delivery trough 1 are in transitional fit. By changing the gap between the sliding paddle 2 and the bottom of the aggregate delivery trough 1, the internal volume can be changed to control the delivery amount of aggregates of different particle sizes.

[0042] like Figure 5 As shown, the spreading and rolling system includes a crawler 13-1, a driven wheel 13-2, a driving wheel 13-3, a trap door 13-4, a comb plate 13-5, an auger 13-6, a crushed stone container 15 and a crushed stone outlet 16, wherein the auger 13-6 is located at the top, moves counterclockwise with a constant speed, and its power comes from the generator 4, which is driven by a belt connected at both ends. The trap door 13-4 is located below the auger 13-6, hingedly connected to the vehicle body, and can only be bounced upwards but not dropped. The driving wheel 13-3 is located below the trap door 13-4 and is driven by the generator 4 to rotate clockwise, driving the track 13-1 and the driven wheel 13-2 to rotate counterclockwise. At the same time, a crushed stone container 15 is provided just below the trap door 13-4, i.e., at one end of the driven wheel. A comb plate 13-5 is also provided between the track 13-1 and the spiral distributor 13-6. The function of the comb plate 13-5 is to make the stones passing through the spiral distributor 13-6 fall evenly on the track 13-1.

[0043] The crawler track 13-1 has an upward tilting angle, and the trap door 13-4 has a downward tilting angle, such as Figure 5 As shown, the two can form a V-shaped groove, and the stone will first fall into the groove, and after being fully mixed by the spiral distributor 13-6, the generator 4 drives the driving wheel 13-3 to rotate clockwise, and the driving wheel 13-3 then drives the crawler 13-1 to rotate, and finally drives the driven wheel 13-2 to rotate together. The constant motor voltage always ensures that the spiral distributor 13-6 rotates counterclockwise at a uniform speed, and the stone is taken out through the crawler 13-1, falls into the gravel container 15, and falls on the construction road surface through the gravel outlet 16, which is located directly below the crawler 13-1.

[0044] The rolling wheel 14 is slightly higher than the wheel so as to tap and compact the spread chip seal.

[0045] Example 2

[0046] Different from the first embodiment, the vehicle body is also equipped with a road surface cleaning and speed control system, wherein the road surface cleaning and speed control system includes a surface cleaning device 6 and a speed meter 10. The surface cleaning device 6 is a wind press that can blow out high-speed airflow to clean up debris and dust on the road surface. The speed meter 10 is installed at the bottom of the vehicle body. Figure 4 As shown, the speed meter 10 can measure the driving speed of the device and transmit the speed data to the speed broadcasting device 5. The speed broadcasting device 5 receives the speed data transmitted by the speed meter 10 and makes the speed fluctuate within a certain range. If the speed fluctuation exceeds the range, it broadcasts a reminder to accelerate or decelerate. The speed broadcasting device 5 is installed on the top of the generator 4, and the generator is set on the asphalt storage device 3.

[0047] Working process

[0048] Step 1: Move the construction device according to the required construction location:

[0049] First, asphalt and crushed stone aggregate are loaded into the asphalt storage device 3 and the aggregate delivery tank 1 respectively, and then the trolley is moved to the road construction position;

[0050] Step 2: Preparation before construction:

[0051] Start the generator 4 to supply power, and set the temperature inside the asphalt storage device 3 so that the inside maintains a suitable temperature. The spiral distributor 13-6 starts working, and after the crushed stone aggregate is fully mixed, the motor drives the driving wheel 13-3 to rotate clockwise, and the driving wheel 13-3 then drives the track 13-1 to rotate, and finally drives the driven wheel 13-2 to rotate together. The constant motor voltage always ensures that the spiral distributor 13-6 rotates counterclockwise at a uniform speed, and the aggregate is carried out through the track 13-1. The surface cleaning device 6 starts working to clean the road ahead. Replace the appropriate asphalt nozzle;

[0052] Step 3: Construction:

[0053] The construction worker stands in front of the trolley and pulls the handle of the trolley. The surface cleaning device 6 blows air to clean up debris and dust on the road surface. The speed broadcasting device 5 starts to work to ensure that the construction device moves forward at a suitable speed. The asphalt spraying device 12 starts to spray asphalt, and then the gravel spreading device 13 spreads aggregate on the sprayed asphalt. Finally, the rolling wheel 14 rolls and taps the aggregate spread on the asphalt to complete the gravel sealing construction work in a small range.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
