It is a mixture of epoxy resin, curing agent and matrix asphalt obtained through complex chemical modification. It is often used as a pavement structure bonding material in road engineering. Epoxy asphalt spreaders play an important role as a device for laying epoxy asphalt on roads.

When in use, the heating mechanism heats the epoxy asphalt in the asphalt tank body. After the heating is completed, the extraction pump extracts the epoxy asphalt in the asphalt tank body into the transfer box, and sprays it to the surroundings from the bottom end of the spray head through the pipeline.

[0004] Regarding the above-mentioned related technologies, since each spray head on the spray truck is fixedly installed at the rear of the vehicle body, when the spraying range needs to be adjusted, relevant personnel are required to manually disassemble and replace the installation position of each spray head to adjust the distance between adjacent spray heads. This increases the workload of relevant personnel and reduces the efficiency of adjustment, so it needs to be improved. Summary of the invention

Each sliding rail 31 is fixedly connected to the transfer box 3 by bolts, and the extending direction is the width direction of the vehicle body 1. The two sliding rails 31 are respectively located on both sides of the width direction of the vehicle body 1.

[0037] Reference Figure 2 In the embodiment of the present application, the adjustment frame 5 is set as two groups, and the two groups of adjustment frames 5 correspond to the two sliding rails 31. Each adjustment frame 5 is mounted on the corresponding sliding rail 31 and is slidingly connected to the sliding rail 31, and the sliding direction is the extension direction of the sliding rail 31.

[0038] Reference Figure 2 and Figure 3The adjustment mechanism 6 includes a driving component 61 and a connecting frame group 62. The driving component 61 includes a driving frame 611 and a sliding member 612. In the embodiment of the present application, the number of the driving frames 611 is set to two, and the two driving frames 611 are distributed in the vertical direction. Each driving frame 611 is slidably connected to the vehicle body 1 through a slide rail, and the sliding direction is the vertical direction.

[0039] Reference Figure 2 and Figure 3 The sliding member 612 includes a driving motor 6121 and a driving screw 6122. The body of the driving motor 6121 is fixedly mounted on the rear of the vehicle body 1 by bolts, and the output shaft is vertically arranged downward. The top of the driving screw 6122 is fixedly connected to the output shaft of the driving motor 6121 by a coupling, and both ends of the driving screw 6122 are rotatably connected to the vehicle body 1 by bearings.

[0040] Reference Figure 2 and Figure 3 , both ends of the driving screw rod 6122 are provided with threads, and the two threads have opposite rotation directions. Both ends of the driving screw rod 6122 pass through the two driving frames 611 respectively, and are both threadedly connected with the corresponding driving frames 611 to realize driving the two driving frames 611.

[0041] Reference Figure 2 and Figure 3 The number of the connecting frame groups 62 is set to be several, and they are arranged one by one corresponding to the adjustment frames 5. The several adjustment frames 5 are respectively located on both sides of the driving frame 611 along the length direction of the sliding track 31. Each connecting frame group 62 includes a first connecting frame 621 and a second connecting frame 622. The middle part of each first connecting frame 621 is rotatably connected to the middle part of the corresponding second connecting frame 622 through a pin shaft, and the rotation connection between the first connecting frame 621 and the second connecting frame 622 is rotatably connected to the corresponding adjustment frame 5 through a pin shaft.

[0042] Reference Figure 2 and Figure 3 One end of each driving frame 611 is rotatably connected to one end of the first connecting frame 621 closest to itself through a pin shaft, and the other end is rotatably connected to one end of the second connecting frame 622 closest to itself through a pin shaft, so that when the driving frame 611 slides, it can drive the corresponding ends of the first connecting frame 621 and the second connecting frame 622 to move together, and make the corresponding ends rotate relative to the driving frame 611.

[0043] Reference Figure 2 and Figure 3The ends of the first connecting frame 621 in each connecting frame group 62 along the length direction are rotatably connected to the ends of the second connecting frame 622 in another adjacent connecting frame group 62, or the ends of the adjacent driving frames 611, through pin shafts, so that the displacement between the several connecting frame groups 62 can be transmitted.

[0044] Reference Figure 2 and Figure 3 In the initial state, that is, when the two driving frames 611 are away from each other, the plurality of adjusting frames 5 are in a state of approaching each other. When the driving motor 6121 drives the driving screw 6122 to rotate, so that the two driving frames 611 are approaching each other, the first connecting frame 621 and the second connecting frame 622 in each connecting frame group 62 are rotated, thereby increasing the distance between the first connecting frame 621 and the second connecting frame 622 in the adjacent connecting frame group 62, thereby making the adjacent adjusting frames 5 move away from each other, thereby changing the spacing between the adjusting frames 5.

[0045] Reference Figure 3 and Figure 4 The top of each adjusting frame 5 is provided with a connecting pipe 51 and a connecting hose 7. One end of each connecting hose 7 is connected to the transfer box 3, and the other end is connected to the corresponding connecting pipe 51. The bottom end of each connecting pipe 51 extends downward and passes through the bottom end of the corresponding adjusting frame 5.

[0046] Reference Figure 3 , Figure 4 and Figure 5 Each adjusting frame 5 is provided with an adjusting mechanism 8, and each adjusting mechanism 8 includes a mounting ring 81, a driving assembly 82, and a plurality of closing pieces 83. Each driving assembly 82 includes a driving ring 821 and a driving rod 822, and each driving ring 821 is sleeved on the bottom of the corresponding communicating pipe 51, and is rotatably connected to the corresponding adjusting frame 5 through a bearing.

[0047] Reference Figure 4 and Figure 5 The bottom wall of each driving ring 821 is penetrated by a plurality of driving grooves 8211, which are arranged at equal angles along the axis of the driving ring 821, and each driving groove 8211 is in an arc shape. Each driving rod 822 is fixedly connected to the closing piece 83, and the driving rods 822 are cylindrical rods. One end of each driving rod 822 extends upward into the corresponding driving groove 8211, and the side walls abut against the inner side walls of the corresponding driving groove 8211.

[0048] Reference Figure 4 , Figure 5 and Figure 6, an extension rod 831 is downwardly arranged at the bottom of each closing piece 83, and the extension rod 831 is integrally formed with the closing piece 83 and is a cylindrical rod. Each mounting ring 81 is located directly below the corresponding connecting pipe 51, and is fixedly mounted on the bottom end of the corresponding adjustment frame 5, and is sleeved on the corresponding driving ring 821, and is rotatably connected to the corresponding driving ring 821.

[0049] Reference Figure 5 and Figure 6 A plurality of restraining grooves 811 are formed through the bottom wall of each mounting ring 81. The plurality of restraining grooves 811 are arranged at equal angles along the circumference of the axis of the mounting ring 81, and the length direction of each restraining groove 811 is inclined. The bottom end of each extension rod 831 extends downward into the corresponding restraining groove 811, and the side walls abut against the inner wall of the corresponding restraining groove 811, so that the closing piece 83 can move along the extension direction of the restraining groove 811.

[0050] Reference Figure 3 and Figure 5 The adjusting frame 5 and the spraying head 4 are arranged one by one, and each spraying head 4 is fixedly installed at the bottom end of the corresponding adjusting frame 5 and extends vertically downward. The top end of each spraying head 4 is fixedly connected to the corresponding mounting ring 81. Each spraying head 4 is connected to the inner ring of the corresponding mounting ring 81, so that the epoxy asphalt flowing out of the connecting pipe 51 can fall into the spraying head 4 through the inner ring of the mounting ring 81.

[0051] Reference Figure 4 and Figure 5 In the initial state, one end of each sealing piece 83 extends to the inner ring of the mounting ring 81, and a plurality of sealing pieces 83 are attached to each other, and a plurality of sealing pieces 83 extend to one end of the inner ring of the mounting ring 81, forming a passage for epoxy asphalt to pass through. When the driving ring 821 rotates, the inner side wall of the driving groove 8211 on the driving ring 821 abuts against the side wall of the driving rod 822, so that the driving rod 822 moves along the extension direction of the driving groove 8211.

[0052] Reference Figure 5 and Figure 6 During this process, each driving rod 822 drives one end of the closing piece 83 to move. At this time, the extension rod 831 on the closing piece 83 moves along the extension of the constraint groove 811, and each closing piece 83 itself rotates, so that one end of each closing piece 83 located at the inner ring of the mounting ring 81 moves toward the outside of the inner ring of the mounting ring 81, and then gradually releases the shielding of the inner ring of the mounting ring 81, thereby realizing the regulation of the epoxy asphalt flow rate.

[0053] Reference Figure 3 and Figure 4Each regulating mechanism 8 further includes a linkage assembly 84 and two redirecting bevel gears 85, one of which is fixedly sleeved on the corresponding driving ring 821, and the other redirecting bevel gear 85 is rotatably connected to the corresponding adjustment frame 5 through a pin. Each linkage assembly 84 includes a linkage member 841, a sliding frame 842, a linkage rack 843 and a linkage gear 844, and each linkage member 841 includes a linkage frame 8411.

[0054] Reference Figure 3 and Figure 4 One end of each linkage frame 8411 is rotationally connected to the first connecting frame 621 or the second connecting frame 622 in the corresponding connecting frame group 62 through a pin shaft, and the other end of each linkage frame 8411 is rotationally connected to the corresponding sliding frame 842 through a pin shaft.

[0055] Reference Figure 3 and Figure 4 Each sliding frame 842 is slidably connected to the corresponding adjustment frame 5 through a slide rail, and the sliding direction of each sliding frame 842 is vertical. Each linkage rack 843 is fixedly connected to the corresponding sliding frame 842, and each linkage rack 843 is meshed with the corresponding linkage gear 844. Each linkage gear 844 is fixedly connected to the redirecting bevel gear 85 in the corresponding regulating mechanism 8 and rotatably connected to the vehicle body 1 through the same pin shaft, so that when the linkage gear 844 rotates, it can drive the two redirecting bevel gears 85 to rotate, thereby causing the driving ring 821 to rotate.

[0056] Reference Figure 3 and Figure 4 In the initial state, that is, when the plurality of adjustment frames 5 are close to each other, one end of each sealing piece 83 extends to the inner ring of the mounting ring 81 to shield the inner ring of the mounting ring 81. When the adjustment frames 5 slide and move away from each other, the first connecting frame 621 drives the corresponding linkage frame 8411 to move, and then the first connecting frame 621 drives the corresponding sliding frame 842 to slide.

[0057] Reference Figure 3 , Figure 4 and Figure 5 At this time, the sliding frame 842 drives the linkage rack 843 to slide together, so that the linkage rack 843 drives the linkage gear 844 to rotate, and then the linkage gear 844 drives the corresponding driving ring 821 to rotate through the corresponding two redirecting bevel gears 85. At this time, the rotation of the driving ring 821 drives the displacement of several sealing pieces 83, so that one end of the sealing piece 83 gradually moves outward from the inner ring of the mounting ring 81, thereby changing the sealing degree of the connecting pipe 51 on the adjusting frame 5, and realizing the adjustment of the epoxy asphalt flow.

[0058] The implementation principle of an epoxy asphalt spreader in an embodiment of the present application is as follows: when the driving motor 6121 drives the driving screw 6122 to rotate, so that the two driving frames 611 approach each other, the first connecting frame 621 and the second connecting frame 622 in each connecting frame group 62 rotate, thereby increasing the distance between the rotating connection points of the first connecting frame 621 and the second connecting frame 622 in adjacent connecting frame groups 62, thereby causing adjacent adjusting frames 5 to move away from each other, thereby changing the spacing between the adjusting frames 5.

[0059] In this process, the first connecting frame 621 drives the corresponding sliding frame 842 to slide, so that the sliding frame 842 drives the linkage rack 843 to slide together, and then the linkage gear 844 drives the corresponding driving ring 821 to rotate through the corresponding two redirecting bevel gears 85. At this time, the rotation of the driving ring 821 drives the displacement of several closing pieces 83, and then one end of the closing piece 83 gradually moves outward from the inner ring of the mounting ring 81, thereby changing the sealing degree of the connecting pipe 51 on the adjusting frame 5, and realizing the adjustment of the epoxy asphalt flow.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
