Description

Technical Field

[0001] This invention relates to the field of road construction equipment technology, and in particular to a multifunctional hot-melt road marking painting device. Background Technology

[0002] Hot-melt road markings are widely used in traffic sign construction on highways, urban roads, and parking lots due to their advantages such as high wear resistance, good reflectivity, and long service life. Currently, many hot-melt road marking painting equipment on the market suffer from problems such as poor equipment adaptability, limited applicability to specific media, limited functionality, inconvenient operation, and unstable marking quality. Existing equipment often uses a straight-cylinder feeding structure, which easily leads to clogging of the hot-melt paint and uneven feeding, affecting the continuity and thickness consistency of the markings. Furthermore, traditional equipment often uses a uniform on / off control for the discharge port, making it impossible to flexibly adjust the line width and shape according to construction needs. This requires changing different specifications of nozzles, making operation cumbersome and reducing construction efficiency. In addition, the relative position of the glass bead spraying component and the paving hopper in some equipment is fixed, making it difficult to adjust according to actual construction conditions, resulting in uneven adhesion of the glass beads and affecting the reflectivity of the markings. Summary of the Invention

[0021] Example like Figure 1-4As shown, a multifunctional hot-melt road marking equipment includes a traveling wheel 1, a mounting frame 2, a paving material box 8, a glass bead spraying assembly 4, a feeding device 6, and a pneumatic control system 7. The traveling wheel 1 is rotatably mounted on both sides of the mounting frame 2. The paving material box 8 is located below the mounting frame 2. The glass bead spraying assembly 4 is connected to the mounting frame 2 via a long optical shaft 3. The feeding device 6 is connected to a transport vehicle via an auger lug 5. The lower end of the feeding device 6 is connected to the inlet of the paving material box 8. The pneumatic control system 7 is located in front of the paving material box and is connected to the mounting frame 2 via a mounting base.

[0022] The feeding device 6 includes a feeding end 63 and a screw pusher 62. One end of the feeding end 63 is connected to the outlet of the heating and insulation container, and the other end is connected to the inlet of the screw pusher 62. The feeding end 63 is located on the upper part of the screw pusher 62 and forms a cross-shaped, equal-diameter four-way design with the screw pusher 62. The screw pusher 62 includes a barrel 622 and a screw mandrel 621. The barrel 622 is inclined, and the screw mandrel 621 is rotatably disposed inside the barrel 622, with one end extending to the outside of the barrel 622 and connected to the drive system 61.

[0023] The paving hopper 8 is fixedly installed at the end of the material cylinder 622, and a storage chamber 81 is formed inside it. The storage chamber 81 is connected to the discharge port of the material cylinder 622. Several discharge ports are arranged at intervals along the length of the bottom of the paving hopper 8, and a gate 71 is rotatably installed at each discharge port. One end of the gate 71 is hinged to the bottom of the paving hopper 8 through a hinge, and the other end is connected to the pneumatic control system 7.

[0024] The pneumatic control system 7 includes multiple cylinders 72, each cylinder 72 corresponding to a discharge port, and the cylinder body of each cylinder 72 is fixedly mounted on the mounting base by a spring seat 73. The end of the piston rod of the cylinder 72 is connected to the gate 71.

[0025] A guide plate 82 is installed at the discharge port. The guide plate 82 is inclined downward and has an angle of 30-45° with the horizontal plane. The guide plate 82 is made of stainless steel and its surface is polished. The cylinder 72 is controlled by a solenoid valve group to independently control the opening and closing of different gates 71, thereby forming paving effects with different line widths and shapes.

[0026] Work process: In operation, the equipment is first connected and secured to the transport vehicle via the auger lug 5, and the feed end 63 is connected to the heating and insulation container. The solenoid valve group's operating program is set according to construction requirements via the control system. The drive system 61 is started, driving the spiral mandrel 621 to rotate. The hot-melt coating enters the spiral pusher 62 through the feed end 63 and, pushed by the spiral mandrel 621, enters the storage chamber 81 of the paving material box 8. The pneumatic control system 7 controls the corresponding cylinder 72 to operate according to the set program. The piston rod of the cylinder 72 extends and retracts, causing the gate 71 to rotate, opening the corresponding discharge port. The hot-melt coating flows out through the guide plate 82, completing the marking paving. Simultaneously, the glass bead spraying assembly 4 sprays glass beads onto the newly paved marking line. The position of the glass bead spraying assembly 4 on the long optical axis 3 can be adjusted to adapt to different marking line positions. When the marking line width needs to be adjusted, simply control different numbers of cylinders 72 to open the corresponding gate 71 via the control system; the operation is convenient and efficient.

[0027] Therefore, the present invention provides a multifunctional hot-melt road marking painting device with the above-mentioned structure, which can be flexibly installed on common transport vehicles, special marking vehicles and other wheeled transport vehicles. It solves the problems of poor adaptability and single applicable carrier of existing equipment. It can adapt to various specifications and forms of road markings, reduce the utilization rate of manpower, improve construction efficiency, reduce the labor intensity of workers, effectively make up for the shortage of professional and technical personnel, and meet diverse construction needs.
