[0038] The stirring device 50 is filled with asphalt mixture and stirs the asphalt mixture, and the screw conveying device 60 conveys the asphalt mixture in the stirring device 50;

[0039] However, the asphalt mixture transported by the screw conveying device 60 can only be discharged from one opening, and the asphalt mixture paved on the ground will be very uneven. For this reason, a uniform paving assembly 70 is connected to the bottom of the screw conveying device 60, and the uniform paving assembly 70 includes fixed plates 16 fixed on both sides of the body 11, and a paving cylinder 18 is fixedly installed between the two fixed plates 16. A material mixing cylinder is rotatably arranged in the paving cylinder 18, and the material mixing cylinder is fixed to the motor shaft of the first motor 37 fixedly arranged on one of the fixed plates 16. The material mixing cylinder is composed of two side plates 29 and two The paving cylinder 18 is composed of two connecting pieces 28, two connecting pieces 28 are symmetrically fixedly arranged between the two side plates 29, two openings are formed between the two side plates 29, and a material receiving assembly is arranged at the position of each opening. The top of the paving cylinder 18 is connected to the spiral conveying device 60, and the bottom of the paving cylinder 18 is provided with a discharge port 27. The material receiving assembly at the bottom discharges asphalt mixture from the discharge port 27, and the material receiving assembly at the top receives asphalt mixture from the spiral conveying device 60. The two material receiving assemblies are driven by the first motor 37 to rotate and discharge asphalt mixture in turn;

[0040] The connecting piece 28 is fitted with the paving tube 18, so that the asphalt mixture in the collecting assembly will not flow out;

[0041] The material receiving assembly includes a material receiving box, the longitudinal length of which is much greater than its transverse width. The discharge port 27 is used in conjunction with the material receiving box, and its longitudinal length is greater than that of the material receiving box. The asphalt mixture received by the material receiving box will fill the material receiving box and will first be in the shape of strips in the material receiving box. In this way, when it is poured out from the material receiving box, it can be laid very evenly on the road, thereby saving a large amount of subsequent construction time and reducing the overall volume of the equipment.

[0042] In order to further optimize the uniformity of the paved asphalt mixture, the applicant has made further improvements to the collecting assembly, specifically:

[0043] The material receiving box is composed of a pair of baffles 30, the two sides between the two baffles 30 are fixed and sealed by a soft layer 34, the bottom between the two baffles 30 is sealed by a flexible layer 31, and the two baffles 30, the flexible layer 31, and the two soft layers 34 form a material receiving box structure with one side open, wherein the flexible layer 31 and the soft layer 34 in the top of the material receiving box are both in a loose state;

[0044] The two baffles 30 at the top are V-shaped and respectively fit with one of the connecting pieces 28 to receive more asphalt mixture and form a seal with the connecting piece 28 to prevent the asphalt mixture from falling from the gap;

[0045] Furthermore, a No. 1 diverter strip 33 and a No. 2 diverter strip 36 are longitudinally arranged at the bottom of the top flexible layer 31, and the No. 1 diverter strip 33 and the No. 2 diverter strip 36 are symmetrically arranged, wherein the No. 2 diverter strip 36 is arranged obliquely forward and downward, and the No. 1 diverter strip 33 is arranged obliquely backward and downward, and the No. 2 diverter strip 36 and the No. 1 diverter strip 33 hold up the flexible layer 31, and the spiral conveying device 60 is fixedly connected to the paving cylinder 18 through the feeding pipe 26, and the feeding pipe 26 is directly opposite to the center position of the No. 1 diverter strip 33 and the No. 2 diverter strip 36. In this way, under the oblique structural setting of the No. 1 diverter strip 33 and the No. 2 diverter strip 36, the asphalt mixture discharged from the feeding pipe 26 can move along the No. 1 diverter strip 33 and the No. 2 diverter strip 36 and evenly fill the entire receiving box.

[0046] The baffle 30 is fixed on the rotating shaft 35, and the two ends of the rotating shaft 35 are rotatably set on the two side plates 29 respectively. The applicant also sets a power component in the paving tube 18 so that the top material receiving box can be deformed into the state of the bottom material receiving box. The two baffles 30 in the bottom material receiving box are formed into a triangular structure, and the opening formed by it is much smaller than the opening formed by the two baffles 30 in the top material receiving box. Because the two baffles 30 in the bottom form a smaller and longitudinally longer opening, the asphalt mixture in the bottom material receiving box can be evenly sprinkled on the road under the action of gravity, so that high-quality asphalt road paving construction can be carried out, and the flexible layer 31 in the bottom material receiving box is stretched into a straight state by the deformation of the two baffles 30, thereby effectively preventing the asphalt mixture from sticking to the flexible layer 31;

[0047] The power assembly includes a gear 45 fixed on each of the rotating shafts 35, and a double-sided rack 44 is meshed between the two gears 45.

The insertion strip 40 will rotate with the material receiving box and move along the track 42. Referring to the drawings of the specification, due to the shape of the track 42, the top The inserting strip 40 will gradually move toward the guide seat 38 when the material receiving box rotates, thereby driving the double-sided rack 44 at the top to move, and the double-sided rack 44 at the top is meshed with the two gears 45 at the top, driving the two rotating shafts 35 at the top to rotate, thereby driving the two baffles 30 at the top to rotate to the bottom state. Similarly, the inserting strip 40 at the bottom will gradually move away from the guide seat 38 when the material receiving box rotates, thereby driving the double-sided rack 44 at the bottom to move, and the double-sided rack 44 at the bottom is meshed with the two gears 45 at the bottom, driving the two rotating shafts 35 at the bottom to rotate, thereby driving the two baffles 30 at the bottom to rotate to the top state.

[0048] The track 42 is a spliced ​​track of two arc sections, and the arc diameter at the top position is greater than the arc diameter at the bottom position.

[0049] The stirring device 50 includes a stirring barrel 13 fixed on the top of the body 11, a stirring chamber 22 is arranged in the stirring barrel 13, a stirring shaft 21 is rotatably installed on the top of the stirring chamber 22, the stirring shaft 21 is fixed to the motor shaft of the second motor 14 fixed on the top of the stirring barrel 13, stirring blades 23 are fixed on the stirring shaft 21, and a feed inlet 15 is fixedly provided on the stirring barrel 13, and asphalt mixture is added through the feed inlet 15. After the second motor 14 is started, the stirring shaft 21 can be driven to rotate, so that the asphalt mixture in the stirring chamber 22 is stirred by each of the stirring blades 23 to prevent the asphalt mixture from sticking.

[0050] The screw conveying device 60 includes a feeding barrel 19 fixed at the bottom of the body 11, the inner cavity of the feeding barrel 19 is connected to the stirring chamber 22, a feeding shaft 24 is rotatably installed in the feeding barrel 19, the feeding shaft 24 is fixed to the motor shaft of the third motor 20, the third motor 20 is fixed to the outside of the feeding barrel 19, and a feeding blade 25 is fixed on the feeding shaft 24. After starting the third motor 20, the feeding shaft 24 is driven to rotate, and the asphalt mixture in the stirring chamber 22 can be successively discharged through the rotation of the feeding blade 25.

[0051] A compaction roller 17 is rotatably mounted on one side of the machine body 11 to compact the discharged asphalt mixture.

[0052] In particular, the flexible layer 31 and the soft layer 34 are made of materials commonly used in the industry for packaging asphalt mixtures, such as polypropylene and polyethylene.
