DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] The embodiment of the present invention provides a painting device that can be used for painting a gravel synchronous sealing vehicle, such as Figure 1 and Figure 2 As shown, the painting device 100 includes a painting frame 1 , a flat brush 2 , a roller brush 3 and a rotating mechanism 4 .

[0052] like Figure 1 and Figure 7 As shown, one end of the painting frame 1 in the first direction is used to connect with the vehicle body 210 of the gravel painting synchronous sealing vehicle 200, and the flat brush 2 and the roller brush 3 are both arranged at the other end of the painting frame 1 in the first direction. When the painting device 100 is installed on the vehicle body 210, the height direction of the vehicle body 210 is usually taken as the first direction, the painting frame 1 is installed at the bottom of the vehicle body 210, and the flat brush 2 and the roller brush 3 are arranged toward the road surface so that the bristles of the flat brush 2 and the roller brush 3 can contact the road surface.

[0053] like Figure 1 and Figure 2As shown, the roller brush 3 extends in the second direction and is rotatably connected to the painting frame 1 along the axis in the second direction, and the rotating mechanism 4 is used to drive the roller brush 3 to rotate. By driving the roller brush 3 to rotate through the rotating mechanism 4 (the rotating mechanism 4 can be a hydraulic motor, etc.), the emulsified asphalt can be evenly applied and fully penetrated into the fine gaps of the original road surface. In addition, when the painting device 100 is installed on the vehicle body 210, the width direction of the vehicle body 210 is usually the second direction. Figure 7 As shown, since the interval between the aggregate spreading device 222 of the aggregate spreading mechanism and the asphalt spreading device 232 of the asphalt spreading mechanism is usually small, the existing drag-type brushing device is usually bulky and cannot be installed between the aggregate spreading device 222 and the asphalt spreading device 232. However, the brushing device 100 adopts a roller brush 3 design, which changes the existing drag-type brushing into active brushing, and relatively increases the contact length between the road surface and the brush per unit area. In this way, the number of brushes can be reduced while ensuring the construction effect, making the structure of the brushing device 100 more compact, which is conducive to installing the brushing device 100 between the aggregate spreading device 222 and the asphalt spreading device 232.

[0054] like Figure 1 and Figure 2 As shown, the flat brush 2 is located on one side of the roller brush 3 in the third direction, and the bristles of the flat brush 2 are arranged at the end of the brushing frame 1 that is connected to the vehicle body 210 and faces away from the brushing frame 1. The flat brush 2 can play a stabilizing role, and even if a higher amount of asphalt is applied, it will not cause flow, so that the sealing layer has a better bonding effect on the original road surface. Among them, the first direction, the second direction and the third direction intersect each other, such as Figure 7 As shown, when the painting device 100 is installed on the vehicle body 210, the direction from the front to the rear of the vehicle body 210 (ie, the length direction of the vehicle body 210) is usually regarded as the third direction.

[0055] The coating device 100 provided in the embodiment of the present invention drives the roller brush 3 to rotate through the rotating mechanism 4, which can evenly apply the emulsified asphalt and fully penetrate into the tiny gaps of the original road surface; the flat brush 2 can play a stabilizing role, and even if a higher asphalt spreading amount is used, it will not cause flow, so that the sealing layer has a better bonding effect on the original road surface. At the same time, the painting device 100 can be installed on the gravel painting synchronous sealing vehicle 200 for use, so that the gravel painting synchronous sealing vehicle 200 can simultaneously have the three functions of asphalt spraying, painting sealing, and stone spreading, which can reduce the number of maintenance equipment, reduce the difficulty of construction, reduce construction costs, and effectively improve the quality and efficiency of asphalt gravel sealing construction; and the painting device 100 adopts a roller brush 3 design, which changes the existing drag-type painting into active painting, improves the painting efficiency, and can reduce the number of brushes while ensuring the construction effect, making the structure of the painting device 100 more compact, which is conducive to installing the painting device 100 between the aggregate spreading mechanism and the asphalt spreading mechanism of the gravel painting synchronous sealing vehicle 200.

[0056] The painting machine frame 1 is provided with a roller brush 3, which may be one or more roller brushes 3, for example, multiple roller brushes 3 may be provided along the second direction and / or the third direction. When multiple roller brushes 3 are provided, the rotating mechanism 4 may be provided with one, that is, multiple roller brushes 3 are driven to rotate simultaneously by one rotating mechanism 4; the rotating mechanism 4 may also be provided with multiple corresponding roller brushes 3, and multiple roller brushes 3 are driven to rotate respectively by multiple rotating mechanisms 4, for example, Figure 1 and Figure 2 As shown, in this embodiment, the roller brush 3 includes a first roller brush 3a and a second roller brush 3b, and the first roller brush 3a and the second roller brush 3b are arranged in parallel in the third direction; the rotating mechanism 4 includes a first rotating mechanism 4a for driving the first roller brush 3a to rotate and a second rotating mechanism 4b for driving the second roller brush 3b to rotate. The arrangement of two roller brushes 3 can improve the construction efficiency and quality of the painting device 100 while ensuring the compact structure of the painting device 100.

[0057] Furthermore, in this embodiment, the rotation directions of the first roller brush 3a and the second roller brush 3b are opposite. The first roller brush 3a and the second roller brush 3b rotate towards each other, which can increase the pressure in a relatively closed area formed by the first roller brush 3a, the second roller brush 3b and the road surface, squeeze the asphalt into the cracks in the road surface, thereby improving the repair effect of the road surface.

[0058] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the roller brush 3 is movable and adjustable along the third direction. In this way, the position of the roller brush 3 can be moved and adjusted according to actual conditions to avoid adhesion between the roller brush 3 and the flat brush 2, or between multiple roller brushes 3.

[0059] Specifically, Figure 3 and Figure 4 As shown, in this embodiment, one end of the roller brush 3 in the second direction is connected to the rotating mechanism 4; two guide rails 11 extending along the third direction are provided at both ends of the painting machine frame 1 corresponding to the roller brush 3 in the second direction, and each guide rail 11 is provided with a slide 12 that can slide along the third direction; the slides 12 on the two guide rails 11 are respectively connected to the rotating mechanism 4 and one end of the roller brush 3 away from the rotating mechanism 4. The setting method of the movement adjustment structure of this roller brush 3 is relatively simple. In addition, when there are multiple roller brushes 3 arranged along the third direction, multiple slides 12 will be provided on each guide rail 11 corresponding to the multiple roller brushes 3, and the multiple slides 12 on each guide rail 11 are respectively connected to one end of the multiple roller brushes 3.

[0060] Further, if Figure 3 and Figure 4 As shown, in this embodiment, at least one of the two guide rails 11 is provided with a self-locking structure 13, and the self-locking structure 13 is used to limit the movement of the roller brush 3 after the roller brush 3 is moved and adjusted. The guide rail 11 has a self-locking function, so that the movement and adjustment of the roller brush 3 and the fixation after adjustment can be achieved. Among them, the self-locking structure 13 can be a self-locking screw connected between the guide rail 11 and a slide seat 12.

[0061] A flat brush 2 is arranged on the painting machine frame 1, and may be arranged with one or more flat brushes 2. For example, a plurality of flat brushes 2 are arranged along the second direction. This arrangement of a plurality of flat brushes 2 is conducive to keeping the painting device 100 compact.

[0062] like Figure 1 and Figure 2 As shown, in this embodiment, the flat brush 2 is rotatably adjusted along an axis in a first direction, so that the flat brush 2 can be rotated and adjusted to an optimal working angle according to different working conditions.

[0063] like Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the painting frame 1 includes a vehicle body connecting member 14, a brush holder 15 and a lifting mechanism 16; the vehicle body connecting member 14 and the brush holder 15 are respectively arranged at the two ends of the painting frame 1 in the first direction, and the vehicle body connecting member 14 is used to connect with the vehicle body 210; the flat brush 2 and the roller brush 3 are arranged on the brush holder 15, and the brush holder 15 is movable and adjustable along the first direction relative to the vehicle body connecting member 14; the lifting mechanism 16 is connected between the vehicle body connecting member 14 and the brush holder 15, so as to move and adjust the brush holder 15 through the lifting mechanism 16. In this way, when the painting device 100 is installed on the vehicle body 210, the flat brush 2 and the roller brush 3 can be lifted and adjusted through the lifting mechanism 16 according to different working conditions.

[0064] Specifically, Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, two vehicle body connectors 14 and lifting mechanisms 16 are provided corresponding to the two ends of the brush holder 15 in the second direction, and each vehicle body connector 14 is connected to a corresponding end of the brush holder 15 in the second direction through a lifting mechanism 16. This ensures that the brush holder 15 can be lifted and lowered smoothly as a whole.

[0065] The flat brush 2 and the roller brush 3 are raised and lowered by the lifting mechanism 16. Specifically, Figure 5 and Figure 6 As shown, in this embodiment, the lifting mechanism 16 includes two mounting columns 161, two rotating rods 162 and a lifting cylinder 163. The two mounting columns 161 extend along the first direction, and the two mounting columns 161 are arranged at intervals in the third direction. The two mounting columns 161 are respectively fixedly connected to the vehicle body connecting member 14 and the brush holder 15; the two rotating rods 162 are arranged in parallel in the first direction, and the two ends of each rotating rod 162 are respectively connected to the two mounting columns 161 so as to be rotatable along the axis in the second direction; the cylinder body and the telescopic rod of the lifting cylinder 163 are respectively connected to the vehicle body connecting member 14 and the brush holder 15 so as to be rotatable along the axis in the second direction. In this way, the lifting mechanism 16 is not only simple in structure, but also can ensure that the brush holder 15 can be lifted and lowered smoothly as a whole. Among them, the lifting cylinder 163 can be a hydraulic cylinder or the like.

[0066] The embodiment of the present invention also provides a synchronous sealing vehicle for applying crushed stone, such as Figure 7 As shown, the gravel painting synchronous sealing vehicle 200 includes a vehicle body 210 , an aggregate spreading mechanism, an asphalt spreading mechanism and a painting device 100 .

In this way, the number of brushes can be reduced while ensuring the construction effect, making the structure of the brushing device 100 more compact, which is conducive to installing the brushing device 100 between the aggregate spreading mechanism and the asphalt spreading mechanism of the gravel painting synchronous sealing vehicle 200.
