[0026] A road paving device for municipal road construction includes a mobile frame 1, the mobile frame 1 includes a vehicle plate frame 15 and four mobile wheels 16, a push-pull rod 17 is provided on the side of the vehicle plate frame 15 close to a material box 8, a raw material box 2 is fixedly provided on the top wall of the mobile frame 1, a control panel 20 is provided on the outer side wall of the raw material box 2, and a feed port 18 and a first motor 19 are provided on the top wall of the raw material box 2.

[0027] By pushing the push-pull rod 17, the paving device can be conveniently pushed to the front of the designated road to be built using the four moving wheels 16, and the width data of the material box 8 for one-time unloading can be adjusted on the control panel 20 according to the erected limit side panels. Asphalt raw materials and the like enter the interior of the raw material box 2 from the feed port 18.

[0028] Since a stirring rod 3 is rotatably arranged inside the raw material box 2, the stirring rod 3 includes a stirring shaft 21 fixedly connected to the output shaft of the first motor 19, and a plurality of stirring paddles 22 are fixedly connected to the outer wall of the stirring shaft 21. The first motor 19 is started to drive the stirring shaft 21 to rotate, and then drive the stirring paddles 22 to rotate, so as to stir and mix the asphalt raw materials to prevent the raw materials from condensing.

[0029] The bottom wall of the vehicle frame 15 is fixedly provided with a first telescopic rod 4, a set of second telescopic rods 5 and a vertical plate 6. The first telescopic rod 4 is fixedly provided on the outermost side of the bottom wall away from the push-pull rod 17, so that after the unloading box 8 unloads the material, the leveling block 7 is located at the rear end of the device to ensure that the final leveling action is not affected.

[0030] A push-flattening block 7 is fixedly provided at the bottom end of the first telescopic rod 4, and telescopic components 25 are also fixedly provided on both sides of the first telescopic rod 4. The telescopic components 25 include an outer round rod 26 and an inner round rod 27. One ends of the outer round rod 26 and the inner round rod 27 are respectively fixedly provided on the top wall of the push-flattening block 7 and the bottom wall of the vehicle plate frame 15, and the other ends are slidably connected through a slide groove 28.

[0031] After the unloading box 8 completes unloading, the control panel 20 controls the first telescopic rod 4 to move downward, and the inner round rods 27 on both sides also move downward along the slide groove 28 driven by the flattening block 7, and together with the outer round rods 26, enhance the stability and directionality of the moving process, until the flattening block 7 moves to a suitable height, and the asphalt raw materials below are flattened and smoothed.

[0032] A group of second telescopic rods 5 are fixedly arranged on both sides of the elastic tube 24, and a discharge box 8 is fixedly arranged at the bottom end of a group of second telescopic rods 5. The discharge box 8 is connected with the raw material box 2 through a conveying pipe 9. The conveying pipe 9 includes a fixed tube 23 and an elastic tube 24. The fixed tube 23 is fixedly arranged inside the vehicle plate frame 15, and its top end penetrates the bottom wall of the raw material box 2, and its bottom end is connected with the top end of the elastic tube 24. An electromagnetic valve 34 is arranged inside the fixed tube 23, and the bottom end of the elastic tube 24 penetrates the top wall of the discharge box 8.

[0033] A second motor 29 is arranged on the outer wall of the material discharge box 8, and a bidirectional screw rod 12 is arranged at the output end of the second motor 29. A bidirectional screw rod 12 is rotatably arranged inside the material discharge box 8, and a group of partitions 13 are slidably arranged on the outer periphery of the bidirectional screw rod 12. Starting the second motor 29 can drive the bidirectional screw rod 12 to rotate, thereby making a group of partitions 13 close or separate along the bidirectional screw rod 12 to adjust the width of the material discharge at one time.

[0034] The control panel 20 issues an opening command to the electromagnetic valve 34, and the asphalt raw material falls from the fixed pipe 23 and along the elastic pipe 24 into the lower material box 8 below, and the raw material fills up the space between a group of partitions 13 in the entire lower material box 8 little by little.

[0035] A group of partitions 13 are respectively slidably arranged on the outer periphery of the forward and reverse threads of the bidirectional screw rod 12, and can be closed or separated from each other. By adjusting the distance between the two partitions 13, the width of the material being discharged at one time is adjusted. The top of the inner wall opposite to each other of a group of partitions 13 is provided with a touch sensor 14, which is an acoustic touch sensor and can sense the touch of an object. Until the touch sensors 14 in the two uppermost corners sense the touch of the asphalt raw material, it is proved that the raw material has been filled once, and information is sent to the control panel 20. After receiving the information, the control panel 20 issues a start instruction to the third motor 30.

[0036] Since the bottom of the material box 8 is movably provided with a bottom plate 10 through a reciprocating screw 11, a third motor 30 is provided on the side wall of the vertical plate 6, and the reciprocating screw 11 is provided at the output end of the third motor 30. After the third motor 30 is started, the reciprocating screw 11 is driven to rotate, and then the bottom plate 10 is driven to move, so as to open or close the bottom opening of the material box 8.

[0037] A group of opposite side walls of the discharge box 8 are provided with grooves 31 and through holes 32. The base plate 10 is an L-shaped structure, one end of which is slidably arranged on the threaded periphery of the reciprocating screw 11, and the other end can slide through the groove 31 and the through hole 32. Another group of opposite side walls of the discharge box 8 are provided with limiting grooves 33, and the side walls of the base plate 10 can move on the limiting grooves 33.

[0038] When it is necessary to open the bottom opening of the discharge box 8 for discharge, the bottom plate 10 moves to the right along the reciprocating screw 11, and the left end of the bottom plate 10 moves out of the groove 31. The bottom plate 10 moves to the right through the through hole 32. When the rightmost end of the bottom plate 10 moves to the rightmost end of the reciprocating screw 11, the leftmost end of the bottom plate 10 is just placed on the through hole 32. After the raw material is discharged, the reciprocating screw 11 is rotated in the opposite direction to move the bottom plate 10 to the left end along the limiting groove 33 until it moves to the inside of the groove 31. At this time, the leftmost end of the bottom plate 10 moves to the leftmost end of the reciprocating screw 11.

[0039] The control panel 20 is connected to the first telescopic rod 4, the second telescopic rod 5, the touch sensor 14, the first motor 19, the electromagnetic valve 34, the second motor 29 and the third motor 30. Different operation schemes can be preset on the control panel 20 according to different road widths, and the unloading and paving are automatically performed in sequence according to the preset schemes.
