[0025] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Refer to the attached Figure 1 and attached Figure 2 The present embodiment provides a high-performance flexible anti-crack seal construction device, including a chassis 1 of a tractor, an asphalt tank 2 and a gravel tank 3 are provided on the chassis 1, a first asphalt spraying mechanism 4, a fiber spreading mechanism 5, a second asphalt spraying mechanism 6 and a gravel spreading mechanism 7 are provided at the lower end of the gravel tank 3, the gravel spreading mechanism 7 is connected to the gravel tank 3 through a feeding chute 8, the fiber spreading mechanism 5 includes a plurality of feeding cavities 51, and the feeding cavities 51 are staggered along the width direction of the chassis 1. This structural design can minimize the impact on the feeding of adjacent feeding cavities 51, and is also conducive to adjusting the fiber spreading width by controlling the feeding of the feeding cavities 51. The material mechanism 7 includes a bulk material trough 71 arranged below the discharge trough 8, and a conveying shaft 72 is rotatably arranged in the bulk material trough 71. The conveying shaft 72 is provided with a first spiral blade 73 and a second spiral blade 74. The rotation directions of the first spiral blade 73 and the second spiral blade 74 are opposite. A plurality of mounting points are provided in the bulk material trough 71, and the mounting points are detachably connected with a first partition 75 and a second partition 76. The discharge trough 8 is located between the first partition 75 and the second partition 76. The first partition 75 and the second partition 76 respectively prevent the gravel from being transported to the two ends of the bulk material trough 71, that is, the distance between the first partition 75 and the second partition 76 is the gravel spreading width. The gravel compartment 3 provides gravel to the gravel spreading mechanism 7 through the discharge chute 8, and the conveying shaft 72 transports the gravel delivered from the discharge chute 8 to the two ends of the bulk chute 71 by rotating the first spiral blade 73 and the second spiral blade 74, so that it is evenly distributed between the first partition 75 and the second partition 76, and then the material is spread. This arrangement can improve the uniformity of gravel spreading; wherein, the spreading width of the gravel is adjusted by adjusting the installation position of the first partition 75 and the second partition 76; the asphalt compartment 2 provides asphalt to the first asphalt spraying mechanism 4 and the second asphalt spraying mechanism 6. The first asphalt spraying mechanism 4 and the second asphalt spraying mechanism 6 are both provided with a plurality of nozzles 41 distributed along the width direction of the chassis 1. The first asphalt spraying mechanism 4 and the second asphalt spraying mechanism 6 adjust the asphalt spreading width by switching the asphalt nozzles 41.

[0027] As another embodiment of the present invention: there are multiple first spiral blades 73 and second spiral blades 74, the length of the blanking chamber 51 is the same as the length of the first spiral blade 73 and the second spiral blade 74, the first partition 75 is distributed between the two first spiral blades 73, and the second partition 76 is distributed between the two second spiral blades 74. After adjusting the gravel spreading width using the first partition 75 and the second partition 76, the fiber spreading width can be adjusted by simply closing the blanking chamber 51 corresponding to the spiral blades outside the first partition 75 and the second partition 76. This structural design facilitates the coordination of the fiber spreading width and the gravel spreading width. It should be noted that the length direction of the blanking chamber 51 is the width direction of the chassis 1.

[0028] As another embodiment of the present invention: the conveying shaft 72 includes a rotating inner shaft 721 and multiple outer shafts 722 sleeved on the inner shaft 721. The outer shafts 722 are detachably connected to the inner shaft 721. The distance between adjacent outer shafts 722 is greater than the width of the first partition 75. The width of the second partition 76 is the same as the width of the first partition 75. The first spiral blade 73 and the second spiral blade 74 are respectively fixed to the outer shaft 722. Specifically, the outer shaft 722 is arranged in a one-to-one correspondence with the first spiral blade 73, and the outer shaft 722 is arranged in a one-to-one correspondence with the second spiral blade 74. When the outer shaft 722 and the inner shaft 721 are not connected together, the inner shaft 721 rotates within the outer shaft 722 without driving the spiral blades thereon to rotate. When the outer shaft 722 and the inner shaft 721 are connected together, the rotation of the inner shaft 721 drives the rotation of the outer shaft 722, thereby driving the rotation of the spiral blades thereon. With this structural design, when the conveying shaft 72 rotates, the first spiral blade 73 and the second spiral blade 74 outside the first partition plate 75 and the second partition plate 76 do not rotate, which can effectively reduce energy consumption.

[0029] As another embodiment of the present invention: Figure 4 and attached Figure 5 The first baffle 75 includes a first baffle 751 and a second baffle 752. The first baffle 751 is provided with a clearance groove that matches the inner shaft 721. During installation, the inner shaft 721 is inserted into the clearance groove of the first baffle 751. The first baffle 751 is then bolted to the bulk material chute 71, and the second baffle 752 is also bolted to the first baffle 751. The upper end of the second baffle 752 is provided with a curved surface that matches the inner shaft 721. The second baffle 752 is used to seal the clearance groove of the first baffle 751. The inner shaft 721 can rotate between the first baffle 751 and the second baffle 752. The first baffle 751 and the second baffle 752 jointly prevent gravel from being transported to the two ends of the bulk material chute 71.

[0030] As another embodiment of the present invention: a plurality of ear plates 754 are provided between the two outer shafts 722 , and both sides of the first baffle 751 are fixed to the ear plates 754 by bolts respectively, and the plurality of ear plates 754 between the two outer shafts 722 constitute an installation point.

[0031] As another embodiment of the present invention: Figure 3 The lower end of the bulk material chute 71 is provided with an opening and closing mechanism 77. This mechanism includes a blanking plate 771 hingedly connected to the bulk material chute 71. Blanking plate 771 forms the bottom of the bulk material chute 71 and is connected to a drive assembly 772 that drives it to swing up and down. Blanking plate 771 swings downward, opening the discharge port of the bulk material chute 71. Gravel falls along blanking plate 771 toward the discharge port. Compared to vertical fall, the inclined distribution of blanking plates 771 after opening the discharge port effectively slows the falling speed of the gravel, which helps improve the distribution of the gravel.

[0032] One embodiment of drive assembly 772 includes a push rod, a rack, and a gear. The push rod is hinged at both ends to the blanking plate 771 and the rack, respectively. The gear meshes with the rack, and the rack is slidably mounted on the frame. The rotation of the gear drives the rack to slide horizontally along the frame. The rack, via the hinged push rod, lifts the blanking plate 771 to close the discharge port of the bulk material chute 71, or lowers the blanking plate 771 via the hinged push rod to open the discharge port of the bulk material chute 71.

[0033] As another embodiment of the present invention, the first baffle 75 further includes a third baffle 753, which is in contact with the first baffle 751 and is fixed to the upper side of the blanking plate 771. The third baffle 753 is slidably connected to the first baffle 751. When the blanking plate 771 swings downward to open the discharge port of the bulk chute 71, the third baffle 753 effectively prevents crushed stone from falling toward the ends of the blanking plate 771.

[0034] An embodiment of detachable connection between the outer shaft 722 and the inner shaft 721: Figure 7 The outer shaft 722 and the inner shaft 721 are fixed by bolt rods 723. The bolt rods 723 are distributed at both ends of the outer shaft 722. The bolt rods 723 are threadedly connected to the outer shaft 722 and the inner shaft 721 respectively.

[0035] As another embodiment of the present invention: Figure 6The upper end of the blanking chamber 51 is provided with a fiber delivery tube 52, which is used to spray fibers into the blanking chamber 51. The aperture of the blanking chamber 51 is much larger than that of the fiber delivery tube 52. The lower end of the blanking chamber 51 is provided with a blanking port 511. The blanking chamber 51 is provided with air inlet pipes 53 on both sides of the fiber delivery tube 52. The air inlet pipes 53 are externally connected to a high-pressure air supply device. A guide plate 54 is provided between the air inlet pipe 53 and the fiber delivery tube 52. The air outlet of the air inlet pipe 53 faces one end of the guide plate 54, and the other end of the guide plate 54 extends to the discharge port of the fiber delivery tube 52. In this structural design, the air inlet pipe 53 blows high-pressure gas toward the guide plate 54, which then guides the gas to the discharge port of the fiber delivery tube 52 through the guide plate 54. The high-pressure gases on both sides interact with each other at the discharge port of the fiber delivery tube 52 to form vortices, which disrupt the fibers delivered from the fiber delivery tube 52, allowing them to be interwoven and evenly distributed. At the same time, the eddy current can effectively slow down the ejection speed of the fiber, making the fiber fabric more stable and reliable.

[0036] As another embodiment of the present invention, flexible baffles 9 are provided on both sides of the lower end of the material drop chamber 51. The first asphalt spraying mechanism 4 is also provided with a flexible baffle 9 on the side close to the material drop chamber 51. The second asphalt spraying mechanism 6 is also provided with a flexible baffle 9 on the side close to the material drop chamber 51. During the stone crushing and fiber spreading process, the flexible baffles 9 can effectively reduce interference between the two.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
