Description

Technical Field

[0001] The invention relates to the technical field of road construction, and in particular to a road marking spraying device for road engineering. Background Art

[0002] Road markings are traffic safety facilities consisting of various lines, arrows, words, raised road signs, etc. marked on the road surface. They are white or yellow in color. The function of road traffic markings is to convey standardized information and to control and guide traffic. When drawing road markings, a painting device is required for painting.

[0003] However, in the use of traditional road marking spraying devices, if the thickness of the road marking spraying needs to be changed according to the requirements of different usage scenarios, construction workers are often required to perform complex manual operations on site, such as manually adjusting the flow valve based on experience. However, this adjustment method lacks precision and requires a lot of time to repeatedly debug the device, which seriously affects the construction progress.

[0004] In view of this, research and improvement are carried out on the existing problems, and a road marking spraying device for road engineering is provided, aiming to solve the problems and improve the practical value through this technology. Summary of the invention

[0015] Preferably, rollers are installed around the bottom of the carrying plate, and a handle is welded on one side of the top of the carrying plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention drives the screw rod to rotate by the motor B, so that the screw rod drives the movable plate to move upward or downward, and the movable plate drives the fixed plate to move upward or downward synchronously, and further the fixed plate drives the connecting rod to move synchronously, and the movement of the connecting rod will push the ring to slide on the guide rod, and the guide rod plays a role in limiting the movement direction of the ring, ensuring that it can only make a linear motion along the axial direction of the guide rod. Due to the magnetic connection between the sealing ball and the magnet, when the ring slides, the sealing ball will be driven to move synchronously through the magnetic action, and the block will also move with the sealing ball, so that the gap between the block and the discharge port of the spray pipe becomes smaller or larger, thereby reducing or increasing the spraying amount of the paint, so that the spraying amount can be automatically adjusted according to the spraying requirements of different roads, and then it can quickly adapt to the diversified requirements of different roads for the thickness of the marking line, realize the precise control of the spraying amount of the paint, greatly improve the efficiency of adjusting the thickness of the marking line during the construction process, reduce the construction time, improve the overall construction progress, and ensure that the quality of the marking line meets the corresponding engineering standards.

[0017] 2. The present invention drives the rotating rod A to rotate by the motor A, so that the stirring blades rotate in a circle around the axis of the rotating rod A, so that the raw materials stored in the storage tank can be fully stirred. The shear force generated by the high-speed rotation of the stirring blades can break up and refine the lumps and agglomerates that may exist in the raw materials, ensuring the uniformity of the raw materials, providing a good material basis for the subsequent accurate and high-quality marking spraying operations, ensuring that the color and texture of the sprayed markings are uniform, and improving the overall quality and aesthetics of the markings.

[0018] 3. The present invention utilizes the circular ring to move downward to drive the mounting seat B to move synchronously. When the mounting seat B moves downward, the rotating plate will change its angle accordingly and drive the mounting seat A to move downward as well. The movement of the mounting seat A drives the rack, and the rack drives the gear A to rotate. The rotation of the gear A will drive the rotating shaft to rotate synchronously. The rotating shaft then drives the ring gear to rotate, and the ring gear drives the gear B to rotate. The rotation of the gear B increases the angle of the stirring blade, so that the stirring blade can cover a larger range during the rotation process, the contact area with the coating is increased, and the turning and stirring force of the coating is enhanced, thereby ensuring that a large amount of coating can be evenly mixed, preventing the occurrence of insufficient local mixing, improving the mixing uniformity of the coating, and then improving the quality of the coating after spraying. On the contrary, when the spraying amount is small, the smaller stirring angle reduces the contact area between the stirring blade and the coating, reduces the stirring resistance, thereby reducing the energy consumption of the motor A, and at the same time avoids excessive stirring to cause changes in the coating performance, ensuring that a uniform coating can be obtained under small flow conditions.

[0019] 4. The present invention uses belt transmission, and the rotating rod A drives the rotating rod B, which in turn rotates the gears C and D in sequence. The gear D drives the ring through the guide rod. Because the magnet is magnetically connected to the sealing ball, the ring drives the sealing ball to rotate, and the sealing ball then drives the sliding rod, the limit rod, and the fixed seat to rotate in sequence, so that the crushing blades in the spray pipe rotate at high speed, breaking the large particles of the paint into small particles, ensuring that the paint passes through the spray head smoothly, maintaining the continuous and stable spraying operation, and improving the quality of the marking line and the aesthetic and practical engineering. At the same time, it reduces the blockage of the spray head, reduces equipment failures and maintenance costs, and extends the service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] 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. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. 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.

[0023] See also Figures 1 to 10As shown, the present invention provides a road marking spraying device for road engineering, comprising a bearing plate 1, a material storage tank 2 is fixedly installed on the top of the bearing plate 1, one end of the material storage tank 2 is connected with a material spraying pipe 3, one end of the material spraying pipe 3 is connected with a box body 4, the bottom end of the box body 4 is connected with a connecting pipe 12, the bottom end of the connecting pipe 12 is connected with a material spraying head 13, a suction pump 5 is fixedly installed on the outer wall of the material spraying pipe 3, a stirring mechanism 6 for stirring paint is arranged inside the material storage tank 2, a flow control mechanism 7 for controlling the spraying amount of paint is arranged inside the material spraying pipe 3, an angle adjustment mechanism 8 for improving the stirring effect of paint is arranged on one side of the flow control mechanism 7, and a crushing mechanism 9 for crushing paint particles is arranged at the bottom end of the spraying pipe 3; See also Figure 3 to Figure 4 As shown, the stirring mechanism 6 includes a rotating rod A601 rotating inside the storage tank 2, a motor A602 is installed on the top of the rotating rod A601, a rotating rod 603 is rotated on the outer wall of the rotating rod A601, and a stirring paddle 604 is fixedly connected to one end of the rotating rod 603.

[0024] It should be noted that when spraying the marking line, start the motor A602, which drives the rotating rod A601 to rotate, so that the stirring paddle 604 rotates in a circle around the axis of the rotating rod A601, so that the raw materials stored in the storage tank 2 can be fully stirred. The shear force generated by the high-speed rotation of the stirring paddle 604 can break up and refine the lumps and agglomerates that may exist in the raw materials, ensuring the uniformity of the raw materials, providing a good material basis for the subsequent precise and high-quality marking spraying operations, ensuring that the color and texture of the sprayed markings are uniform, and improving the overall quality and aesthetics of the markings.

[0025] See also Figures 1 to 8 As shown, the flow control mechanism 7 includes a regulating valve 701 installed on the outer wall of the injection pipe 3, a sealing ball 702 is arranged inside the regulating valve 701, a blocking block 703 is fixedly connected to the top of the sealing ball 702, a limiting plate 704 is sleeved on the outer wall of the injection pipe 3, a guide rod 705 is fixedly connected to the top of the limiting plate 704, a circular ring 706 is slidably arranged on the outer wall of the guide rod 705, a magnet 707 is installed inside the circular ring 706, a slide rail 708 is welded to the bottom end of the supporting plate 1, a screw rod 709 is installed inside the slide rail 708, a motor B710 is fixedly installed on the top of the screw rod 709, a moving plate 711 is threadedly connected to the outer wall of the screw rod 709, one end of the moving plate 711 is fixedly connected to the fixed plate 712, the injection head 13 is passed through and fixed inside the fixed plate 712, a connecting rod 713 is fixedly connected to one side of the fixed plate 712, and one end of the connecting rod 713 slides on the outer wall of the circular ring 706.

[0026] See also Figure 2As shown, the number of the spray heads 13 is multiple groups, and the multiple groups of spray heads 13 are distributed in a linear array along the axial direction of the fixing plate 712 .

[0027] See also Figure 8 As shown, the sealing ball 702 is made of ferrite stainless steel material, the number of magnets 707 is arranged in multiple groups, and the sealing ball 702 is magnetically connected to the magnets 707.

[0028] It should be noted that when it is necessary to deal with scenarios such as community roads and sidewalks that require lower marking line thickness, first start the motor B710 to rotate forward, and the motor B710 drives the screw 709 to rotate, so that the screw 709 drives the movable plate 711 to move upward, and the movable plate 711 simultaneously drives the fixed plate 712 to move upward, and the fixed plate 712 further drives the connecting rod 713 to move upward. The upward movement of the connecting rod 713 will push the ring 706 to slide upward on the guide rod 705, and the guide rod 705 plays a role in limiting the movement direction of the ring 706, ensuring that it can only move in a straight line along the axial direction of the guide rod 705. Due to the magnetic connection between the sealing ball 702 and the magnet 707, when the ring 706 slides upward, the sealing ball 702 will be driven to move upward synchronously through the magnetic force, and the block 703 will also move upward with the sealing ball 702, so that the gap between the block 703 and the discharge port of the spray pipe 3 becomes smaller, thereby reducing the amount of paint sprayed. On the contrary, when encountering a scenario where thicker markings need to be sprayed, such as the main lane markings of highways, the driving lane markings of large parking lots, etc., the motor B710 is started to reverse, and the movable plate 711 drives the connecting rod 713 to move downward, thereby causing the ring 706 to slide downward on the guide rod 705. Similarly, due to the magnetic connection, the sealing ball 702 and the block 703 will move downward accordingly, increasing the gap between the block 703 and the discharge port of the spray pipe 3, and increasing the amount of paint sprayed. Therefore, the device can automatically adjust the spraying amount according to the spraying requirements of different roads, and can quickly adapt to the diverse requirements of different roads for the thickness of the markings, thereby realizing the precise control of the amount of paint sprayed, greatly improving the efficiency of adjusting the thickness of the markings during construction, reducing construction time, improving the overall construction progress, and ensuring that the quality of the markings meets the corresponding engineering standards.

[0029] In addition, when the marking spraying needs of the previous scene are completed, the device can quickly and automatically adapt to the marking spraying needs of the next scene without manual intervention and adjustment, and promptly meet the marking spraying needs of the next scene, ensuring that the road marking construction can quickly and smoothly transition from one scene to the next, effectively guaranteeing the overall construction progress.

[0030] See also Figures 3 to 6As shown, the angle adjustment mechanism 8 includes a shell 801 welded to the bottom end of the supporting plate 1, a rotating shaft 802 is rotated inside the shell 801, a gear A803 is fixedly connected to the bottom end of the rotating shaft 802, a rack 804 meshing with the gear A803 is slid through a through groove inside the shell 801, a mounting seat A805 is welded to one end of the rack 804, a mounting seat B806 is movably mounted on the outer wall of the ring 706, the mounting seat A805 and the mounting seat B806 are rotatably connected via a rotating plate 807, a gear ring 808 is sleeved on the outer wall of the rotating shaft 802 located inside the rotating rod A601, and a gear B809 meshing with the gear ring 808 is fixedly connected to one end of the rotating rod 603.

[0031] It should be noted that when the ring 706 moves downward, the ring 706 drives the mounting seat B806 to move downward synchronously. When the mounting seat B806 moves downward, the rotating plate 807 will change its angle accordingly and drive the mounting seat A805 to move downward as well. The mounting seat A805 is welded to one end of the rack 804, so the movement of the mounting seat A805 will directly drive the rack 804 to slide in the through groove inside the shell 801. Since the rack 804 and the gear A803 are meshed with each other, when the rack 804 slides, it will apply a circumferential driving force to the gear A803, causing the gear A803 to start rotating. The rotation of the gear A803 will drive the rotating shaft 802 to rotate synchronously, and the rotating shaft 802 will then drive the gear ring 808 to rotate. One end of the rotating rod 603 is fixedly connected to The gear B809 meshing with the ring gear 808 will interact with the gear B809 when the ring gear 808 rotates, driving the gear B809 to rotate. When the gear B809 rotates, it will drive the stirring blade 604 to rotate to a certain angle through the rotating rod 603 connected thereto, so that the angle of the stirring blade 604 increases. At this time, the angle of the stirring blade 604 increases. When the ring 706 moves downward, it means that the amount of paint sprayed is large. The angle of the stirring blade 604 is increased, so that the stirring blade 604 can cover a larger range during the rotation process, increase the contact area with the paint, and enhance the turning and stirring force of the paint, thereby ensuring that a large amount of paint can be evenly mixed, preventing the occurrence of insufficient local mixing, improving the mixing uniformity of the paint, and then improving the quality of the paint after spraying. On the contrary, when the spraying amount is small, the smaller stirring angle reduces the contact area between the stirring blade 604 and the paint, reduces the stirring resistance, thereby reducing the energy consumption of the motor A602, and at the same time avoids excessive stirring to cause changes in the paint performance, ensuring that a uniform paint can be obtained under low flow conditions.

[0032] See also Figures 7 to 10As shown, the crushing mechanism 9 includes an installation box 901 welded to one side of the supporting plate 1, a rotating rod B902 is rotatably provided inside the installation box 901, a gear C903 is fixedly connected to the bottom end of the rotating rod B902, a gear D904 meshing with the gear C903 is rotatably provided on the outer wall of the spray pipe 3, a mounting frame 905 is fixedly connected inside the spray pipe 3, a fixed seat 906 is rotatably provided on the top end of the mounting frame 905, a plurality of groups of crushing blades 907 are fixedly connected to the outer wall of the fixed seat 906, a limiting rod 908 is fixedly connected to the top end of the fixed seat 906, a sliding rod 909 is fixedly connected to the bottom end of the sealing ball 702, and a driving mechanism is arranged between the rotating rod A601 and the rotating rod B902.

[0033] See also Fig.10 As shown, a slide groove 910 is provided inside the limiting rod 908 , and both sides of the bottom end of the slide rod 909 slide inside the slide groove 910 .

[0034] See also Figure 7 As shown, the driving mechanism includes two sets of rotating wheels 911 and a belt 912 . The two sets of rotating wheels 911 are respectively sleeved on the outer wall of the rotating rod A601 and the outer wall of the rotating rod B902 . The two sets of rotating wheels 911 are connected through the belt 912 .

[0035] It should be noted that when the rotating rod A601 rotates, the rotating wheel 911 connected thereto rotates accordingly, and through the transmission effect of the belt 912, the rotating rod B902 is driven to rotate synchronously. The rotation of the rotating rod B902 causes the gear C903 to also start to rotate. Due to the meshing relationship between the gear C903 and the gear D904, the gear C903 drives the gear D904 to rotate. When the gear D904 rotates, the gear D904 drives the ring 706 to rotate through the guide rod 705. Since the magnet 707 is magnetically connected to the sealing ball 702, the ring 706 drives the sealing ball 702 to rotate, and further the sealing ball 70 2 drives the slide bar 909 at the bottom to rotate, and the slide bar 909 drives the limit rod 908 to rotate, thereby rotating the fixed seat 906. The rotation of the fixed seat 906 drives the crushing blade 907 to rotate inside the spray pipe 3. The fast-rotating crushing blade 907 can effectively crush the larger particles in the paint, breaking the large particles into smaller particles so that they can pass through the spray head 13 smoothly, ensuring the smooth spraying of the paint, ensuring the continuity and stability of the road marking spraying operation, improving the quality of the marking spraying, making the sprayed markings more uniform and clear, and improving the aesthetics and practicality of the entire road project. At the same time, it reduces the equipment maintenance and cleaning work caused by the blockage of the spray head 13, reduces the equipment failure rate and maintenance cost, and extends the service life of the equipment.

[0036] See also Figure 3As shown, a motor A602 is installed on the top of the rotating rod A601, and there are multiple groups of stirring paddles 604. The multiple groups of stirring paddles 604 are distributed in a circular array along the axis of the rotating rod A601, which can stir the paint in different areas at the same time, greatly shortening the time required for the paint to be evenly mixed.

[0037] See also Figure 1 As shown, rollers 10 are installed around the bottom of the carrying plate 1, and a handle 11 is welded to one side of the top of the carrying plate 1.

[0038] Working principle: When spraying the marking line, start the motor A602, which drives the rotating rod A601 to rotate, so that the stirring blade 604 rotates in a circle around the axis of the rotating rod A601, so that the raw materials stored in the storage tank 2 can be fully stirred. The shear force generated by the high-speed rotation of the stirring blade 604 can break up and refine the lumps and agglomerates that may exist in the raw materials, ensuring the uniformity of the raw materials, providing a good material basis for the subsequent precise and high-quality marking spraying operations, ensuring that the color and texture of the sprayed markings are uniform, and improving the overall quality and aesthetics of the markings; When it is necessary to deal with scenes with lower requirements for marking line thickness such as community roads and sidewalks, first start the motor B710 to rotate forward, and the motor B710 drives the screw 709 to rotate, so that the screw 709 drives the movable plate 711 to move upward, and the movable plate 711 simultaneously drives the fixed plate 712 to move upward, and the fixed plate 712 further drives the connecting rod 713 to move upward, and the upward movement of the connecting rod 713 will push the ring 706 to slide upward on the guide rod 705, and the guide rod 705 plays a role in limiting the movement direction of the ring 706, ensuring that it can only move in a straight line along the axial direction of the guide rod 705. Due to the magnetic connection between the sealing ball 702 and the magnet 707, when the ring 706 slides upward, the sealing ball 702 will be driven to move upward synchronously through the magnetic force, and the block 703 will also move upward with the sealing ball 702, so that the gap between the block 703 and the discharge port of the spray pipe 3 becomes smaller, thereby reducing the amount of paint sprayed. On the contrary, when encountering a scene where thicker markings need to be sprayed, such as the main lane markings of highways, the lane markings of large parking lots, etc., the motor B710 is started to reverse, and the moving plate 711 drives the connecting rod 713 to move downward, thereby causing the ring 706 to slide downward on the guide rod 705. Similarly, due to the magnetic connection, the sealing ball 702 and the block 703 will move downward accordingly, increasing the gap between the block 703 and the discharge port of the spray pipe 3, and increasing the spraying amount of the paint. Therefore, the device can automatically adjust the spraying amount according to the spraying requirements of different roads, and can quickly adapt to the diverse requirements of different roads for the thickness of the markings, thereby realizing the precise control of the spraying amount of the paint, greatly improving the efficiency of adjusting the thickness of the markings during the construction process, reducing the construction time, improving the overall construction progress, and ensuring that the quality of the markings meets the corresponding engineering standards; In addition, when the circular ring 706 moves downward, the circular ring 706 drives the mounting seat B806 to move downward synchronously. When the mounting seat B806 moves downward, the rotating plate 807 will change its angle accordingly and drive the mounting seat A805 to move downward as well. The mounting seat A805 is welded to one end of the rack 804, so the movement of the mounting seat A805 will directly drive the rack 804 to slide in the through groove inside the shell 801. Since the rack 804 and the gear A803 are meshed with each other, when the rack 804 slides, a driving force in the circumferential direction will be applied to the gear A803, causing the gear A803 to start rotating. The rotation of the gear A803 will drive the rotating shaft 802 to rotate synchronously, and the rotating shaft 802 will drive the gear ring 808 to rotate. One end of the rotating rod 603 is fixedly connected to the gear Gear B809 meshed with ring 808, when ring 808 rotates, it will interact with gear B809 and drive gear B809 to rotate. When gear B809 rotates, it will drive stirring blade 604 to rotate to a certain angle through rotating rod 603 connected thereto, so that the angle of stirring blade 604 increases. At this time, the angle of stirring blade 604 increases. When ring 706 moves downward, it means that the amount of paint sprayed is large. The angle of stirring blade 604 is increased so that stirring blade 604 can cover a larger range during rotation, increase the contact area with the paint, and enhance the turning and stirring force of the paint, thereby ensuring that a large amount of paint can be evenly mixed, preventing the occurrence of insufficient local mixing, improving the mixing uniformity of the paint, and then improving the quality of the paint after spraying. On the contrary, when the spraying amount is small, the smaller stirring angle reduces the contact area between stirring blade 604 and the paint, reduces the stirring resistance, thereby reducing the energy consumption of motor A602, and at the same time avoids excessive stirring to cause changes in paint performance, ensuring that uniform paint can be obtained under small flow conditions; At the same time, when the rotating rod A601 rotates, the rotating wheel 911 connected thereto rotates accordingly, and through the transmission effect of the belt 912, the rotating rod B902 is driven to rotate synchronously. The rotation of the rotating rod B902 causes the gear C903 to also start to rotate. Due to the meshing relationship between the gear C903 and the gear D904, the gear C903 drives the gear D904 to rotate. When the gear D904 rotates, the gear D904 drives the ring 706 to rotate through the guide rod 705. Since the magnet 707 is magnetically connected to the sealing ball 702, the ring 706 drives the sealing ball 702 to rotate, and the sealing ball 702 further drives the sealing ball 702 to rotate. The sliding bar 909 at the bottom of the paint is rotated, and the sliding bar 909 drives the limit rod 908 to rotate, thereby rotating the fixed seat 906. The rotation of the fixed seat 906 drives the crushing blade 907 to rotate inside the spray pipe 3. The fast-rotating crushing blade 907 can effectively crush the larger particles in the paint, breaking the large particles into smaller particles so that they can pass through the spray head 13 smoothly, ensuring the smooth spraying of the paint, ensuring the continuity and stability of the road marking spraying operation, improving the quality of the marking spraying, making the sprayed markings more uniform and clear, and improving the aesthetics and practicality of the entire road project. At the same time, it reduces the equipment maintenance and cleaning work caused by the blockage of the spray head 13, reduces the equipment failure rate and maintenance cost, and extends the service life of the equipment.
