[0002] With the development of the country and the development of public transportation, more and more roads are being repaired and manufactured. As the service life of roads increases, the road surface will gradually be damaged. At this time, the damaged road surface needs to be repaired or patched. In order to ensure the quality of the repair, the asphalt roadbed around the damaged road surface needs to be cut as a whole to make it a patch pit with a regular shape, so that the new asphalt filled in the pit can fit the ground better. At present, ordinary cutting machines or other chiseling tools are used to cut square patch pits. The asphalt roadbed will be very hard during cutting, which will seriously affect the cutting efficiency and the cutting difficulty is also large, which is not suitable for operation. Utility Model Content

[0006] By adopting the above technical solution, water can be injected into the interior of the box through the water injection port, and water can be discharged to the other side of the box through the drip pipe. The speed of the water flow can be adjusted by adjusting the valve, so that water can drip into the evaporation plate to form steam, so that the water can evaporate rapidly and in large quantities and be discharged from the steam pipe, so that the water can be evaporated to form water vapor.

[0007] Preferably, the outer surface of the steam pipe passes through the outer surface of the shell, and a steam nozzle is provided inside the shell and fixedly mounted on the outer surface of the steam pipe, with the nozzle of the steam nozzle facing the ground directly.

[0008] By adopting the above technical solution, the water vapor evaporated by the evaporation plate will enter the shell through the steam pipe, so that the water vapor is ejected outward through the steam nozzle, and the high temperature of the water vapor is used to heat the ground.

[0009] Preferably, a steam recovery mechanism is provided inside the shell, and the steam is recovered by the steam recovery mechanism.

[0010] By adopting the above technical solution, a part of the water vapor can be condensed so that the formed water exists in the inclined plate.

When cutting is required, the block only needs to be pushed up to disengage the support rod from the block, and the auxiliary wheel can be lifted to allow the cutting wheel to contact the ground for cutting, which facilitates the raising and lowering of the shell and allows the shell to be pulled at will.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the asphalt roadbed cutting device capable of softening the ground:

[0020] 1. The drip pipe and regulating valve can drain the water on one side of the box, allowing the water in the box to enter the evaporation plate, and the water will evaporate through the heating of the evaporation plate. The evaporated water will form high-temperature water vapor, and the pressure generated by evaporation will be discharged from the steam pipe to the outside, allowing the water vapor to be ejected from the steam nozzle along the steam pipe to heat the asphalt foundation and soften the asphalt foundation;

[0021] 2. When the high-temperature steam is ejected and the asphalt foundation is heated, the steam will float upwards. At this time, along with the rotation of the fan, part of the steam will be sucked into the shell, so that the steam passes through the condensation plate, and the low temperature of the condensation plate condenses the steam, allowing the water produced after condensation to drip into the inclined plate. Then, the condensed water is sent back into the box through the rotation of the peristaltic pump. At the same time, the one-way valve is used to prevent water from flowing back, thereby improving the utilization rate of water and reducing water loss;

[0022] 3. Lift the block to lower the support rod, disengage the auxiliary wheel from the ground, and allow the cutting wheel to contact the ground to cut the ground. After cutting the foundation, you can directly step on the support rod and push the support rod to move the auxiliary wheel forward, allowing the auxiliary wheel to push the block away. When one side of the block contacts one end of the support rod, you can release the support rod and push the block back through the spring, so that the support rod, the ground and the shell form a triangle, propping up the shell and facilitating the movement of the shell.

[0032] Water is injected into the box body 3 through the water injection port, and then the regulating valve 5 is opened to adjust the water outlet speed of the drip pipe 4, so that the drip pipe 4 releases water, and the water released from the drip pipe 4 is quickly evaporated by the heating of the evaporation plate 6. The evaporated water vapor generates pressure and is discharged from the steam pipe 7, so that a large amount of water vapor is sprayed onto the ground through the steam nozzle 8, thereby heating the asphalt roadbed on the ground and softening the asphalt roadbed.

[0033] A steam recovery mechanism is provided inside the shell 1, and steam is recovered by the steam recovery mechanism. The steam recovery mechanism includes: a condensation plate 9, which is fixedly installed inside the shell 1, and the outer surface of the condensation plate 9 is provided with a through hole, a fan 10 is installed through the outer surface of the shell 1 on one side close to the box body 3, and the fan 10 is located between the condensation plate 9 and the box body 3, and an inclined plate 11 is fixedly installed on the side of the box body 3 close to the steam nozzle 8, a peristaltic pump 12 is fixedly installed on the side surface of the shell 1, and the input end of the peristaltic pump 12 passes through the side surface of the shell 1, and the input end of the peristaltic pump 12 is arranged at the bottom of the inclined plate 11, the output end of the peristaltic pump 12 is connected to the side surface of the box body 3, and a one-way valve 13 is provided on the outer surface of the output end of the peristaltic pump 12.

When the position is reached, the block 18 can be disengaged from the support rod 16 by simply lifting it, and the auxiliary wheel 17 can be retracted away from the ground, so that the shell 1 is lowered with the wheel 2 as the center, and the cutting wheel 15 can contact the ground for cutting. When the use is completed, the support rod 16 can be raised so that the support rod 16 pushes the block 18. When the spring 19 pushes the block 18 back, the support rod 16 can be released. At this time, the support rod 16 will form a triangular support between the ground and the shell 1, lifting the shell 1 and facilitating the movement of the device.
