Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0020] An automated road paving robot includes a chassis 1. Inside the chassis 1, a base frame 2 and a top frame 3 are installed. It should be noted that the base frame 2 is located in the lower part of the chassis 1, and the top frame 3 is located in the upper part of the chassis 1. Several reinforcing rods 4 are fixed between the base frame 2 and the top frame 3. The reinforcing rods 4 serve to reinforce the base frame 2 and the top frame 3, prevent loosening, and provide strong stability. In detail: The base frame 2 includes a frame body 201 and a base plate 202. The base plate 202 is fixed to the bottom of the frame body 201. The frame body 201 reinforces the base plate 202 and prevents it from deforming during use, thus providing strong stability. In detail: The top frame 3 includes a frame body 201 and a top plate 302. The top plate 302 is fixed to the bottom of the frame body 201. The frame body 201 is used to reinforce the top plate 302 and prevent the top plate 302 from deforming during use; it has strong stability. A single-axis drive source 5 is installed at the center of the top plate 302. It should be noted that the single-axis drive source 5 is a single-axis servo motor. The drive end of the single-axis drive source 5 passes through the top plate 302 and is fixed with a first rotating shaft 6. The bottom end of the first rotating shaft 6 is fixed with a drive assembly 7. The drive assembly 7 is installed on the bottom plate 202. The single-axis drive source 5 can drive the drive assembly 7 through the first rotating shaft 6 so that the drive assembly 7 can be rotated and adjusted on the bottom plate 202. In detail: the drive assembly 7 includes a main bevel gear 701 rotatably mounted at the center of the base plate 202, and two auxiliary bevel gears 702 meshing on the main bevel gear 701, with the axes of the two auxiliary bevel gears 702 located on the same straight line; so that the bevel gear 701 can drive the two auxiliary bevel gears 702 to rotate and adjust in different directions; Two sets of push components 8 are installed on the top of the base plate 202, and the two sets of push components 8 are connected to the drive component 7 so that the drive component 7 can provide power to the push components 8; In detail: The pushing component 8 includes a "U"-shaped fixed bracket 801 fixed to the top of the frame body 201, and a sliding rod 802 is slidably installed inside the fixed bracket 801 so that the sliding rod 802 can slide and adjust along the length direction of the frame body 201. A drive rod 803 is installed inside the sliding rod 802 in a telescopic manner, and one end of the drive rod 803 passes through the sliding rod 802 and is fixedly connected to the axis of the secondary bevel gear 702. When the secondary bevel gear 702 drives the drive rod 803 to rotate, the drive rod 803 can drive the sliding rod 802 to extend and retract. More specifically: a spiral sliding groove 8031 ​​is provided on the outer circumferential surface of the drive rod 803, and a drive shaft 8021 is fixed on the inner circumferential wall of the sliding rod 802. The drive shaft 8021 is slidably installed inside the sliding groove 8031. If the drive rod 803 rotates, the drive shaft 8021 and the sliding groove 8031 ​​can provide driving force to the sliding rod 802. Normally, a rotating support (not shown in the figure) is fixedly and rotatably mounted on the drive rod 803 near the secondary bevel gear 702, and the rotating support is fixed to the top of the base plate 202. The rotating support can provide support for the drive rod 803 and ensure that the drive rod 803 rotates stably. Telescopic components 9 are respectively provided on both sides of the pushing component 8, and the telescopic components 9 are installed on the frame body 201. The two telescopic components 9 are symmetrically arranged about the pushing component 8. Several telescopic components 9 (usually two telescopic components 9) located on the same side are connected to the same drive plate 10, and the drive plate 10 is installed outside the chassis 1. The telescopic components 9 are used to drive the drive plate 10 so that the drive plate 10 can be adjusted along the width direction of the chassis 1. In detail: the telescopic assembly 9 includes a fixed cylinder 901 fixed to the frame body 201, and a telescopic rod 902 is slidably installed inside the fixed cylinder 901. It should be noted that the telescopic rod 902 slides along the width direction of the chassis 1, and one end of the telescopic rod 902 extends to the outside of the chassis 1 and is fixedly connected to the inner side wall of the drive plate 10. It should also be noted that rotating supports 903 are respectively fixed to the side walls of the telescopic rod 902 and the sliding rod 802, and the same first-order rotating support is rotatably installed between the corresponding rotating supports 903. The push rod 904, it should be noted, is a triangular structure formed by the sliding rod 802, the telescopic rod 902 and the first push rod 904; when the sliding rod 802 pushes the telescopic rod 902 through the first push rod 904, the two telescopic rods 902 can simultaneously provide thrust to the drive plate 10, so that the two drive plates 10 can move in relative or opposite directions, thereby changing the distance between the two drive plates 10; so that the moving components 18 on the sides of the two drive plates 10 can travel on roads of different widths, which has strong practicality; Support bases 20 are installed at both ends of the top of the top plate 302, and a dual-axis drive source 16 is installed on the support base 20. It should be noted that the dual-axis drive source 16 is a dual-axis motor. Telescopic adjustment components 17 are installed at the two drive ends of the dual-axis drive source 16, and one end of the telescopic adjustment component 17 extends to the outside of the chassis 1 and connects to the moving component 18 on the outer wall of the drive plate 10. Through the cooperation of the dual-axis drive source 16 and the telescopic adjustment component 17, the moving component 18 can be driven to move, so that the moving component 18 can drive the chassis 1 to move on the road; thereby ensuring the normal use of the robot. In detail: The telescopic adjustment assembly 17 includes a rotating drum 1701 fixed to the drive end of the dual-axis drive source 16, and a telescopic shaft 1702 is slidably installed inside the rotating drum 1701 along the axial direction, so that the telescopic shaft 1702 can slide and adjust along the axial direction of the rotating drum 1701; thereby, it can be flexibly adjusted according to the distance between the two drive plates 10. It should be noted that: a number of guide grooves 1703 are equidistantly opened on the inner circumferential wall of the rotating drum 1701, and the number of guide grooves 1703 are arranged parallel to the axis of the rotating drum 1701; a number of guide rods 1704 are equidistantly fixed on the outer circumferential surface of the telescopic shaft 1702, and the number of guide rods 1704 are slidably installed inside the guide grooves 1703 respectively. Through the cooperation of the guide grooves 1703 and the guide rods 1704, a limiting function is played, which can prevent the rotating drum 1701 and the telescopic shaft 1702 from rotating in opposite directions, and can ensure that power is provided to the moving assembly 18. In detail: The moving assembly 18 includes a main drag chain wheel 1801 fixed to the end of the telescopic shaft 1702. Several auxiliary drag chain wheels 1802 are rotatably mounted on the outer wall of the drive plate 10. It should be noted that the auxiliary drag chain wheels 1802 are located below the drive plate 10 and are aligned in a straight line. The same track 1803 is driven onto the two main drag chain wheels 1801 and the several auxiliary drag chain wheels 1802, enabling movement on roads. It should also be noted that the outer wall of the drive plate 10 is equidistantly fixed with... Several mounting shafts 1805 are provided, and protective plates 1802 are mounted on these mounting shafts 1805. The protective plates 1805 serve a protective function, reducing the risk of damage to the main drag chain wheel 1801 or the auxiliary drag chain wheel 1802 from collisions with external objects. It should be noted that each mounting shaft 1805 is threaded with a hexagonal nut 1806, which secures the protective plate 1804 and effectively prevents it from becoming loose.

[0021] Adjustable plates 12 are symmetrically arranged on the lower part of the base plate 202. It should be noted that one end of the adjustable plate 12 is adjusted by rotating with the bottom of the base plate 202, so that the width of the adjustable plate 12 can be flexibly adjusted according to the width of the road, which has strong practicality. A first paving component 13 is installed on one end of each adjustable plate 12. The first paving component 13 is used to push the sand and gravel in the middle of the road to both sides. Several second paving components 14 are installed at equal intervals on the adjustable plate 12. The arrangement of several second paving components 14 plays the role of paving sand and gravel. In detail: The first paving component 13 includes a first motor 1301. The drive end of the first motor 1301 passes through the adjustment plate 12 and is fixed with a second rotating shaft 1302. A plurality of first actuating plates 1303 are fixed at equal intervals on the outer circumference of the second rotating shaft 1302. When the first motor 1301 drives the plurality of first actuating plates 1303 to rotate through the second rotating shaft 1302, it can push the sand and gravel on the road to both sides. In detail: The second paving component 14 includes a second motor 1401. The drive end of the second motor 1401 passes through the adjusting plate 12 and is fixed to a rotating disk 1402. Several second actuating plates 1403 are fixed at equal intervals along the circumferential direction at the bottom of the rotating disk 1402. The second actuating plates 1403 are used to pave sand and gravel. It should be noted that a fixed shaft 1404 is fixed at the axis of the rotating disk 1402. One end of the several second actuating plates 1403 is fixedly connected to the fixed shaft 1404, thereby reinforcing the second actuating plates 1403 and reducing the possibility of deformation of the second actuating plates 1403. An adjustment assembly 15 is installed at the center of the bottom of the base plate 202, and the adjustment assembly 15 is coaxially arranged with the main bevel gear 701. The adjustment assembly 15 is connected to two adjustment plates 12. When the main bevel gear 701 is working, the adjustment assembly 15 can provide driving force to the two adjustment plates 12 so that the adjustment plates 12 can be angled at the bottom of the base plate 202. In detail: The adjustment assembly 15 includes a drive shaft 1501 fixed at the center of the main bevel gear 701, and an adjustment plate 1502 is fixed at the bottom end of the drive shaft 1501 through the housing 1. It should be noted that a bearing (not shown in the figure) is fixed at the connection between the drive shaft 1501 and the base plate 202. The bearing allows the drive shaft 1501 to rotate more smoothly on the base plate 202. The circumferential surface of the adjustment plate 1502 has a protrusion 1503 integrally formed about the center of the shaft. A second push rod 1504 is hinged on each protrusion 1503, and the other end of the second push rod 1504 is hinged to the hinge seat 1505 integrally formed on the inner side wall of the adjustment plate 12. Through the cooperation of the drive shaft 1501, the adjustment plate 1502, the protrusion 1503 and the second push rod 1504, the tilt angle of the adjustment plate 12 can be adjusted, which has strong practicality. Support structures 29 are installed at the corners of the lower part of the chassis 1. When the robot is being adjusted, the support structures 19 can support the robot body 1, so that the moving component 18 can be adjusted without contact with the ground, which can save more effort. In detail: the support structure 29 includes a cylinder 2901 fixed inside the chassis 1, and the drive end of the cylinder 2901 extends to the outside of the chassis 1 and is fixed with a support plate 2902. When the cylinder 2901 drives the support plate 2902 to extend and retract, the support plate 2902 can support the ground. A storage box 19 is installed on the top of the casing 1 for storing sand and gravel. A material discharge channel 20 extends from the top of the casing 1. A support plate 25 is also fixed inside the casing 1, and a conical discharge hopper 26 is fixed on the support plate 25. The inlet of the conical discharge hopper 26 is located directly below the material discharge channel 20. A flexible discharge pipe 27 is sealed to the discharge port of the conical discharge hopper 26. The bottom end of the discharge pipe 27 is sealed to the discharge port 28 opened at the bottom of the casing 1. The discharge port 28 is located between the two first paving components 12. A mounting bracket 22 is fixed to the inner top wall of the casing 1, and a motor 23 is fixed on the mounting bracket 22. The motor 23 is connected to the screw conveyor assembly 21 installed in the discharge pipe 20 through the transmission assembly 24. When the motor 23 drives the screw conveyor assembly 21 to rotate through the transmission assembly 24, it can convey the sand and gravel in the storage box 19 downward.

[0022] In detail: The screw conveyor assembly 21 includes a conveyor shaft 2101 coaxially arranged with the discharge channel 20, and a screw conveyor plate 2102 is fixed on the conveyor shaft 2101. It should be noted that the outer circumferential surface of the screw conveyor plate 2102 is fitted with the inner circumferential wall of the discharge channel 20. When the conveyor shaft 2101 drives the screw conveyor plate 2102 to rotate, the screw conveyor plate 2102 can convey the sand and gravel downward. In detail: The transmission assembly 24 includes an external gear ring 2401 rotatably mounted at the bottom of the feeding channel 20 and a main gear 2402 fixed at the bottom of the motor 23. The external gear ring 2401 and the main gear 2402 are meshed together. Several connecting rods 2403 are fixed along the circumferential direction on the inner circumferential wall of the external gear ring 2401. The connecting rods 2403 are coaxially arranged with the conveying shaft 2101. Through the cooperation of the external gear ring 2401, the main gear 2402 and the connecting rods 2403, the screw conveying assembly 21 can be driven to rotate, so that the screw conveying assembly 21 can work normally.

[0023] Working principle When paving roads, the road paving robot can be adjusted according to the width of the road, making it adaptable to roads of different widths. When adjusting the paving robot, firstly, the robot body is supported so that the moving component 18 of the paving robot is detached from the ground; then, the paving robot is adjusted flexibly according to the width of the road; after adjustment, the paving robot falls to the ground and paves the road gravel. When supporting the paving robot, several cylinders 2901 are activated at the same time. The cylinders 2901 extend and drive the support plate 2902 to move down, thereby supporting the paving robot and making the moving component 18 on the side of the paving robot non-contact with the ground. When adjusting the paving robot, first turn on the single-axis drive source 5; the single-axis drive source 5 can drive the main bevel gear 701 to rotate through the first rotating shaft 6, and the main bevel gear 701 can drive the two auxiliary bevel gears 702 to rotate while also driving the adjustment plate 1502 to rotate. Two secondary bevel gears 702 can drive the drive rod 803 to rotate. Through the cooperation of the sliding groove 8031 ​​and the drive shaft 8021, the sliding rod 802 can be driven to slide on the fixed bracket 801. The fixed bracket 801 can push the telescopic rod 902 through the first push rod 904 so that the telescopic rod 902 can move inside the fixed cylinder 901. The two telescopic rods 902 located on the same side can push the adjustment plate 12 on the same side, thereby changing the gap between the two adjustment plates 12, so that the moving components 18 on the sides of the two adjustment plates 12 can adapt to roads of different widths. During the rotation of the adjusting plate 1502, the two protrusions 1503 can drive the second push rod 1504, and the two second push rods 1504 can simultaneously push the adjusting plate 12, so that the two adjusting plates 12 can rotate on the base plate 202 respectively, thereby adjusting the tilt angle of the adjusting plate 12. This allows the first paving component 13 and several second paving components 14 at the bottom of the adjusting plate 12 to be suitable for ground of different widths, which has strong practicality. Once the paving robot has been adjusted, cylinder 2901 is opened, which allows cylinder 2901 to drive support plate 2902 to retract upward, so that moving component 18 can be supported on the ground. When paving the road, the dual-axis drive source 16 is turned on first. The two output shafts of the dual-axis drive source 16 drive the main drag chain wheel 1801 to rotate through the telescopic rotating component 17. The two main drag chain wheels 1801 and several auxiliary drag chain wheels 1802 located on the same side can drive the track 1803 to transmit power, so that the paving robot can move on the ground. When paving a road, the motor 23 is turned on first. The motor 23 drives the screw conveyor 21 in the material feeding channel 20 to rotate through the transmission component 24, thereby feeding sand and gravel onto the road. Then, the first paving component 13 and several second paving components 14 are turned on. Through the cooperation of the first paving component 13 and the second paving components 14, the sand and gravel on the road can be paved. When sand and gravel are dumped onto the road, the motor 23 is turned on. The motor 23 drives the external gear ring 2401 to rotate through the main gear 2402. The external gear ring 2401 drives the conveyor shaft 2101 to rotate through the connecting rod 2043. The conveyor shaft 2101 can drive the spiral conveyor plate 2102 to rotate. The spiral conveyor plate 2102 can dump the sand and gravel, so that the sand and gravel are dumped onto the road in sequence through the conical hopper 26, the flexible discharge pipe 27 and the discharge port 28. When paving a road, the first motor 1301 and several second motors 1402 are turned on simultaneously. The first motor 1301 drives several first actuating plates 1303 to rotate through the second rotating shaft 1302.
