[0031] As shown in the figure, Figure 2 and Figure 3 the center of the lower surface of the pressing seat 3 is provided with a pouring cavity 31, the lower surface of the mounting seat 2 is mounted with a motor 21, the output shaft of the motor 21 extends in the vertical direction and rotates through the pressing seat 3, the output shaft of the motor 21 is coaxially provided with a crushing piece which can sink into the pouring cavity 31 and rotate in the pouring cavity 31, the crushing piece is a crushing disc 22 which is rotatably embedded in the pouring cavity 31, the lower surface of the crushing disc 22 is provided with a plurality of first material guide grooves 23, and the side wall of the crushing disc 22 is provided with a plurality of second material guide grooves 24, the first material guide grooves 23 and the second material guide grooves 24 correspond to each other and communicate with each other.

[0032] In the process of road repair, the worker will push the vehicle body 1, so that the pouring cavity 31 is located directly above the pit, then the electric cylinder 41 will drive the mounting seat 2 to descend, the mounting seat 2 will drive the pressing seat 3 to descend and press on the road surface through the elastic telescopic rod 51, the elastic telescopic rod 51 will be gradually compressed in the process of the mounting seat 2 continuing to descend, the pressing seat 3 will be stationary, and the mounting seat 2 will drive the crushing disc 22 to descend in the pouring cavity 31 through the motor 21, the motor 21 will drive the crushing disc 22 to rotate and crush the road surface at the pit, and the crushed material generated when the road surface is crushed will move to the edge of the crushing disc 22 through the first material guide grooves 23, and then move upward away from the road surface through the second material guide grooves 24, so that the crushed material can be discharged in time.

[0033] The upper surface of the mounting seat 2 is mounted with two vertically arranged limiting rods 42 which are slidably arranged through the vehicle body 1 in the vertical direction, thereby improving the stability of the mounting seat 2 in the lifting process.

[0036] It is worth mentioning that the elastic telescopic rod 51 will press the lower surface of the pressing base 3 against the road surface. The pressing force between the pressing base 3 and the road surface ensures the stability of the vehicle body 1 during the road repairing process. The blocking of the pressing base 3 makes the dust generated during the breaking of the road surface float into the material injection cavity 31, and the dust in the material injection cavity 31 can only enter the dust collector 61 through the dust guide channel 63 and the dust suction pipe 62, so that the escape of the dust is avoided.

At this time, the conductive block 83 will abut against the power supply block 82. The power supply 81 will supply power to the dust collector 61 through the power supply block 82 and the conductive block 83, so that the dust collector 61 can be automatically turned on and collect the broken material.

[0039] When the lower surface of the breaking disc 22 is not lower than the lower surface of the pressing base 3, the breaking disc 22 will be separated from the road surface and sink into the material injection cavity 31. At this time, the conductive block 83 will be separated from the power supply block 82.
