Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a road marking trolley. Background Technology

[0002] The structural design of road marking carts (road marking machines) varies depending on their type (hot melt, cold spray, and dust-spreading type) and function, but the core components and principles are basically the same. They generally include a frame and a walking system, an adjustable push rod, and integrated control buttons (such as start / stop and speed adjustment). The core coating system, depending on the type, includes at least one of the following: a hot melt hopper, a cold spray storage tank, or a dust-spreading box. Combined with a spraying / scraping unit, such as a spray gun, it achieves line marking. In addition, existing road marking carts can also be equipped with blowers and air nozzles to blow away road dust and improve marking quality. However, their effectiveness in cleaning large areas of large, difficult-to-remove ground debris is limited, and they lack a more efficient ground dust removal system. Therefore, further improvement and optimization are needed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a road marking vehicle to solve one or more of the problems mentioned above.

[0004] To achieve the above objectives, this utility model provides a road marking cart, including a frame with wheels connected to the bottom end of the frame:

[0005] A material tank is located at the top of the middle section of the frame, and a spray gun is connected to the bottom of the material tank for spraying towards the ground.

[0006] A push handle is connected to the top of the rear end of the frame, and a rotating drum is rotatably connected to the bottom of the front end of the frame. A cleaning roller is horizontally connected to the bottom of the rotating drum. Multiple cleaning rollers are spaced along the outer circumference of the rotating drum. A cleaning brush is provided on the outer side of the cleaning roller. One end of the cleaning roller is connected to a roller shaft. One end of the roller shaft passes through the rotating drum and is rotatably connected to the rotating drum. A transmission part is provided at the bottom of the rotating drum to drive the axial rotation of each roller shaft, thereby driving the cleaning roller to rotate axially.

[0007] The top of the front end of the frame is connected to a drive box, which contains a drive component for driving the drum to rotate axially.

[0008] Preferably, a guide bar is connected to the front end of the frame.

[0009] Preferably, a cleaning nozzle is provided at the bottom of the vehicle frame, located between the rotating drum and the spray gun, for spraying air to clean the ground.

[0010] Preferably, the transmission unit includes a main bevel gear rotatably connected to the bottom end of the rotating drum, a driven bevel gear connected to one end of the roller shaft that passes through the rotating drum, a rotating cylinder provided at the bottom end of the rotating drum, a secondary bevel gear connected to the output end of the rotating cylinder, and the driven bevel gear and the secondary bevel gear meshing with the main bevel gear respectively.

[0011] Preferably, a limiting block is elastically connected to the cleaning roller, a sleeve is sleeved on the outer side of the cleaning roller, one end of the sleeve is designed to be open, a limiting hole matching the limiting block is opened on the sleeve, and a cleaning brush is located on the outer periphery of the sleeve.

[0012] The beneficial effects of this utility model are as follows: A material tank is provided at the top of the middle section of the frame, which is connected to a spray gun at the bottom of the matching material tank for spraying the ground. A pusher is connected to the top of the rear end of the frame for pushing the frame forward to achieve straight lines or lines of different shapes on the road surface. At the same time, a rotating drum is rotatably connected to the bottom of the front end of the frame, and a cleaning roller is horizontally connected to the bottom of the rotating drum. A cleaning brush is provided on the outer side of the cleaning roller. In use, the rotating drum is driven to rotate axially by the drive component, which drives the cleaning roller to rotate horizontally. The cleaning roller is located at the front end of the line. The rotating cleaning brush cleans the ground, especially removing dust and large, hard-to-remove debris. The transmission part can synchronously drive the axial rotation of each cleaning roller to further improve the cleaning effect. The transmission part can also be initially static. When dust accumulates or wears down the bottom surface of the cleaning brush, causing the cleaning efficiency to decrease, the transmission part is controlled to move, driving the cleaning brush to rotate and switch to different cleaning surfaces to maintain efficient cleaning.

[0020] A road marking cart includes a frame 1, wheels 2 connected to the bottom of the frame 1, a material tank 3 at the top of the middle of the frame 1, a spray gun 4 connected to the bottom of the material tank 3 for spraying the ground, a pusher frame 5 connected to the top of the rear of the frame 1, a rotating drum 6 rotatably connected to the bottom of the front of the frame 1, a cleaning roller 7 horizontally connected to the bottom of the rotating drum 6, multiple cleaning rollers 7 spaced apart along the outer periphery of the rotating drum 6, cleaning brushes 8 on the outer side of the cleaning rollers 7, a roller shaft 71 connected to one end of the cleaning roller 7, one end of the roller shaft 71 passing through the rotating drum 6 and rotatably connected to the rotating drum 6, a transmission part at the bottom of the rotating drum 6 for driving the roller shafts 71 to rotate axially, thereby driving the cleaning rollers 7 to rotate axially, and a drive box 9 connected to the top of the front of the frame 1, a drive component inside the drive box 9 for driving the rotating drum 6 to rotate axially.

[0021] like Figure 1 , Figure 2As shown, this utility model is based on the existing conventional road marking trolley (road marking machine) structural design, including a frame 1, with wheels 2 connected to the bottom of the frame 1, and a material tank 3 located at the top of the middle of the frame 1. The material tank 3 can be designed based on different existing marking types (e.g., hot melt type, cold spray type, ash type), and is combined with a spray gun 4 connected to the bottom of the matching material tank 3 for spraying towards the ground. A push handle 5 is connected to the top of the rear of the frame 1 for pushing the frame 1 forward to achieve straight or straight road marking. Different shaped markings are used, and a rotating cylinder 6 is rotatably connected to the bottom of the front end of the frame 1. The rotating cylinder 6 is a vertical cylindrical shape, and a cleaning roller 7 is horizontally connected to the bottom end of the rotating cylinder 6. Multiple cleaning rollers 7 are spaced apart along the outer circumference of the rotating cylinder 6. Cleaning brushes 8 are provided on the outer side of the cleaning rollers 7. Specifically, the cleaning rollers 7 can be designed as cylindrical rollers, and the axial direction of the cleaning rollers 7 is designed to be parallel to the radial direction of the rotating cylinder 6. One end of the cleaning roller 7 is connected to a roller shaft 71, and one end of the roller shaft 71 passes through the rotating cylinder 6. The frame 1 is rotatably connected to the rotating drum 6. The bottom of the rotating drum 6 is equipped with a transmission unit for driving the axial rotation of each roller shaft 71, which in turn drives the cleaning roller 7 to rotate axially. At the same time, the top of the head end of the frame 1 is connected to a drive box 9, which contains a drive component. Thus, when in use, the frame 1 is pushed forward to draw lines of the corresponding shape. At the same time, the drive component drives the rotating drum 6 to rotate axially, which in turn drives the cleaning roller 7 to rotate laterally. The cleaning roller 7 is located at the front end of the line and uses the rotating cleaning brush 8 to clean the ground, especially to remove dust and large, hard-to-remove debris. Compared with existing single blowers and air nozzles, the cleaning effect is better. The transmission unit can synchronously drive the axial rotation of each cleaning roller 7 to further improve the cleaning effect. The transmission unit can also be initially static. When dust accumulates or wears down the bottom surface of the cleaning brush 8, causing the cleaning efficiency to decrease, the transmission unit is controlled to move, driving the cleaning brush 8 to rotate and switch between different cleaning surfaces to maintain efficient cleaning.

[0022] Among them, such as Figure 1 , Figure 2 As shown, the driving component may include a drive motor disposed in the drive box 9, an external gear rotatably connected in the drive box 9, and an external gear ring fixedly wrapped around the outer periphery of the top of the rotating drum 6. The external gear ring meshes with the external gear, and the drive motor drives the external gear to rotate, thereby driving the external gear ring and the rotating drum 6 to rotate axially. The top of the rotating drum 6 may be designed as an opening.

[0023] In the embodiments of this utility model, optionally, such as Figure 1 As shown, a guide rod 10 is connected to the front of the head end of the frame 1. When pushing the frame 1 forward, observing the guide rod 10 helps to maintain the direction of the marking.

[0024] In the embodiments of this utility model, optionally, such as Figure 1As shown, a cleaning nozzle 11 is provided at the bottom of the frame 1, between the rotating drum 6 and the spray gun 4. The cleaning nozzle 11 can be connected to an air pump, blower, etc., installed on the frame 1 to achieve air jet cleaning of the ground.

[0025] In the embodiments of this utility model, optionally, such as Figure 2 As shown, the transmission unit includes a main bevel gear 12 rotatably connected to the bottom end of the inner drum 6, a driven bevel gear 13 connected to one end of the roller shaft 71 that passes through the inner drum 6, a rotary cylinder 14 provided at the bottom end of the inner drum 6, and a secondary bevel gear 15 connected to the output end of the rotary cylinder 14. The driven bevel gear 13 and the secondary bevel gear 15 are respectively meshed with the main bevel gear 12. Thus, when it is necessary to control the axial rotation of the roller shaft 71, the rotary cylinder 14 is controlled to drive the secondary bevel gear 15 to rotate, which in turn drives the main bevel gear 12 and the driven bevel gear 13 to rotate, thereby realizing the axial rotation of the roller shaft 71. The bottom side end of the rotary drum 6 can be provided with an inspection port, which can be equipped with a switch door for inspecting the circuit and equipment, as well as replacing the power supply battery, etc.

[0026] Among them, such as Figure 1 As shown, the pusher frame 5 includes a vertical frame and a control panel connected to the top of the vertical frame. Horizontal handles for hand gripping are connected to both sides of the top of the vertical frame.

[0027] In the embodiments of this utility model, optionally, such as Figure 2 As shown, a limiting block 72 is elastically connected to the cleaning roller 7, and a sleeve 16 is sleeved on the outside of the cleaning roller 7. One end of the sleeve 16 is designed to be open, and a limiting hole matching the limiting block 72 is opened on the sleeve 16. The cleaning brush 8 is located on the outer periphery of the sleeve 16. Thus, when in use, the sleeve 16 is sleeved on the outside of the cleaning roller 7 from its open end, and the limiting block 72 passes through the limiting hole to achieve the limiting. That is, the sleeve 16 moves synchronously with the cleaning roller 7. After a certain period of use, the sleeve 16 can be easily replaced.
