[0022] Wherein, the support rod 8 can prevent the fixed rod 7 from bending downward, so that the fixed rod 7 always keeps horizontal state.

[0023] That is, by the operator pushing the hand push rod 3, the whole device moves forward, during the movement, the moving mechanism 9 will first pre-pave the asphalt concrete, and then the roller wheel 6 will continuously pave the pre-paved concrete.

[0024] In an embodiment of the utility model, the front end of two fixed rods 7 is fixed through connecting shaft 71, preventing two fixed rods 7 from bending inward.

[0025] In an embodiment of the utility model, the moving mechanism 9 includes U-shaped support plate 91, electric hydraulic rod 92, push rod 93, gear box 94, transmission assembly 95 and pre-pressing block 96;The both ends of U-shaped support plate 91 are fixed on the middle part of the upper end of fixed rod 7 respectively, electric hydraulic rod 92 is fixedly installed on U-shaped support plate 91, and the output shaft of electric hydraulic rod 92 slides through the upper end surface of U-shaped support plate 91, push rod 93 is C-shaped and is arranged along the front and back direction, gear box 94 is fixed between two fixed rods 7, and gear box 94 is located at the front side of U-shaped support plate 91, transmission assembly 95 is arranged at the front side of U-shaped support plate 91, and pre-pressing block 96 is fixed at the rear end of U-shaped support plate 91.

[0026] Specifically, please refer to Figure 2 , electric hydraulic rod 92 can drive push rod 93 to reciprocate up and down, and push rod 93 drives pre-pressing block 96 to reciprocate up and down.

[0027] In one embodiment of the utility model, the transmission assembly 95 includes rack 951, pivot shaft 952, straight gear 953, bevel gear one 954, positioning rod 955, rotating rod 956, bevel gear two 957 and push plate 958;The rack 951 is fixed at the front side end of the push rod 93, and the rack 951 is slid through the gear box 94, the pivot shaft 952 is rotatably arranged in the mutually close side of two fixed rods 7, the straight gear 953 is fixed at the middle part of the pivot shaft 952, and the straight gear 953 is located in the gear box 94, the straight gear 953 is engaged with the rack 951, the bevel gear one 954 is symmetrically arranged with two, is fixed on the pivot shaft 952 on the two sides of straight gear 953 respectively, the positioning rod 955 is symmetrically arranged with two, and one end is fixed at the mutually close end of two fixed rods 7 respectively, the two positioning rods 955 are fixed with the sleeve ring at the mutually close end, the rotating rod 956 is arranged with two, is rotatably arranged in two sleeve rings respectively, and the lower end of the rotating rod 956 is rotatably through the gear box 94, the bevel gear two 957 is symmetrically arranged with two, is fixed on the upper end of two rotating rods 956 respectively, and the bevel gear one 954 is engaged with the bevel gear two 957, the push plate 958 is symmetrically arranged with two, is fixed on two rotating rods 956 respectively, and two push plates 958 are all located below the gear box 94.

[0028] It should be explained that the working principle of the electric hydraulic rod 92 is to convert electric energy into hydraulic energy, and then convert hydraulic energy into mechanical energy, so as to realize the linear motion of the push rod. It drives the hydraulic pump to generate high-pressure oil through the motor, and the oil enters the oil cylinder after being controlled by the valve, and the piston rod is pushed to complete the push-pull action. This mechanism makes the electric hydraulic rod not only be able to drive in a single direction, but also be able to drive in the opposite direction, that is, realize reciprocating linear motion.

[0029] Please refer to Figures 3 to 4 , the electric hydraulic rod 92 drives the push rod 93 to move up and down reciprocatingly, and the push rod 93 can push the rack 951 to move up and down reciprocatingly. Specifically, initially, the push rod 93 is at the uppermost end, and the two push plates 958 are in the gathering state, when the push rod 93 pushes the rack 951 to move downward, the rack 951 is engaged with the straight gear 953, so as to drive the straight gear 953 to rotate clockwise, the straight gear 953 can drive the pivot shaft 952 to rotate clockwise, the pivot shaft 952 can drive the bevel gear one 954 on the two sides of the straight gear 953 to rotate clockwise synchronously, since the bevel gear one 954 is engaged with the bevel gear two 957, therefore, the two bevel gear two 957 can drive the two rotating rods 956 to rotate outward synchronously, the two rotating rods 956 can drive the two push plates 958 to turn outwards synchronously, so that the two push plates 958 can spread the accumulated asphalt concrete, so that the asphalt concrete is evenly spread on the roadbed surface;

[0030] When the push rod 93 pushes the rack 951 to move upwards, the rack 951 meshes with the spur gear 953, thereby driving the spur gear 953 to rotate counterclockwise, the spur gear 953 drives the shaft 952 to rotate counterclockwise, the shaft 952 can drive the bevel gear one 954 on both sides of the spur gear 953 to rotate counterclockwise synchronously, since the bevel gear one 954 meshes with the bevel gear two 957, therefore the two bevel gear two 957 drive the two rotating rods 956 to rotate inward synchronously, the two rotating rods 956 can drive the two push plates 958 to converge synchronously, thereby the two push plates 958 can reach the state of gathering again, so the two push plates 958 can perform the action of cyclically pushing and scattering the concrete during the movement.

[0031] Specifically, in the implementation, first, the operator pushes the hand push rod 3 to move forward intermittently, when stopping moving, the electro-hydraulic rod 92 drives the push rod 93 to move up and down reciprocatingly once, during which, when the push rod 93 pushes the rack 951 to move downwards, the rack 951 meshes with the spur gear 953, thereby driving the spur gear 953 to rotate clockwise, the spur gear 953 drives the shaft 952 to rotate clockwise, the shaft 952 can drive the bevel gear one 954 on both sides of the spur gear 953 to rotate clockwise synchronously, since the bevel gear one 954 meshes with the bevel gear two 957, therefore the two bevel gear two 957 drive the two rotating rods 956 to rotate outward synchronously, the two rotating rods 956 can drive the two push plates 958 to evert outward synchronously; when the push rod 93 pushes the rack 951 to move upwards, the rack 951 meshes with the spur gear 953, thereby driving the spur gear 953 to rotate counterclockwise, the spur gear 953 drives the shaft 952 to rotate counterclockwise, the shaft 952 can drive the bevel gear one 954 on both sides of the spur gear 953 to rotate counterclockwise synchronously, since the bevel gear one 954 meshes with the bevel gear two 957, therefore the two bevel gear two 957 drive the two rotating rods 956 to rotate inward synchronously, the two rotating rods 956 can drive the two push plates 958 to converge synchronously, thereby the two push plates 958 can reach the state of gathering again, that is to say, during the time period when the whole device stops, the two push plates 958 can scatter the accumulated concrete, and then can restore to the initial position, so as to scatter the new concrete pile next time, while the above process is completed, the push rod 93 can also drive the pre-pressing block 96 to pre-compact the concrete scattered last time, during the movement of the whole device, the roller 6 can continuously roll the pre-compact part, so that the asphalt concrete surface reaches the flat state, thus completing the whole paving process.

[0032] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
