Description

Technical Field

[0001] This utility model relates to the field of release agent spraying, specifically to a road asphalt release agent spraying device. Background Technology

[0002] When paving roads with asphalt, transport vehicles are needed to transport the asphalt. Because asphalt has a high viscosity, it is difficult for dump trucks to remove the asphalt adhering to their surfaces during transport and unloading. To prevent asphalt from adhering to the surface of the truck bed, an anti-adhesion agent is usually sprayed inside the truck bed. Existing spraying equipment mainly relies on manual spraying, which is not only inefficient but also results in poor uniformity of spraying. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a road asphalt material release agent spraying device.

[0004] This utility model is achieved through the following technical solution:

[0005] A road asphalt release agent spraying device includes a support column and a liquid supply system on its side. A rotating frame that can rotate is arranged laterally on one side of the upper part of the support column. Two sliders are slidably connected by a slide rail inside the rotating frame. A sprayer is connected to the lower part of the slider. The spraying distance between the two sliders is adjusted by a transmission component inside the rotating frame.

[0006] Further optionally, the transmission assembly includes a threaded rod rotatably supported in the center of the slide rail inside the rotating frame. The threaded rod has transmission threads on both sides with opposite directions of rotation that are screwed into the corresponding sliders. An adjustment motor that drives the threaded rod to rotate is connected to the outer end of the rotating frame.

[0007] Alternatively, the sprayer includes a vertically downward spray pipe fixed to a slider, with an inwardly inclined tube connected to the bottom of the spray pipe, and several atomizing nozzles installed on the outside of the inclined tube and the spray pipe.

[0008] Further optionally, the liquid supply system includes a storage tank for holding the release agent, which is pressurized by a pressure pump and transported along a delivery pipe. The outlet of the delivery pipe is connected to the corresponding spray pipe inlet via two connecting hoses, and a control valve is installed on the delivery pipe.

[0009] Alternatively, a rotary motor is installed on the outside of the support column, and the main shaft of the rotary motor is connected to the rotating frame for drive.

[0010] Alternatively, a laser beam is installed on the side of the support column. The laser beam is electrically connected to the controller, which is electrically connected to the pressure pump, the rotary motor, and the regulating motor. The controller is also electrically connected to the audible alarm installed on its top.

[0011] Compared with existing technologies, the advantages of this utility model are: by setting two sprayers with adjustable spacing inside the rotating frame, this utility model can not only achieve uniform automatic spraying of release agent onto the transport vehicle compartment, but also adapt to vehicles of different widths, making it more adaptable to spraying vehicles of different sizes.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1 As shown, a road asphalt release agent spraying device includes a support column 5 and a liquid supply system on its side. A rotating frame 6 is horizontally arranged on one side of the upper part of the support column 5. Two sliders 9 are slidably connected to a slide rail 8 opened in the rotating frame 6. The slide rail 8 is a cross slide rail, and the corresponding sliders 9 are also cross-shaped. A sprayer is connected to the lower part of the sliders 9. The spraying distance between the two sliders 9 is adjusted by a transmission component set in the rotating frame 6. The spraying distance adjustment can adapt to transport vehicles of different widths, and its adaptability is wider.

[0018] like Figure 1 , 2 As shown, the transmission assembly includes a threaded rod 10 rotatably supported in the center of the slide rail 8 inside the rotating frame 6. The two sides of the threaded rod 10 are provided with transmission threads with opposite directions of rotation and screwed to the corresponding sliders 9. The two transmission threads with different directions of rotation on the left and right sides can realize the synchronous movement of the two sliders 9 and adjust the distance between them when the same threaded rod 10 rotates. The outer end of the rotating frame 6 is connected to an adjustment motor 11 that drives the threaded rod 10 to rotate. The adjustment motor 11 is a stepper motor, which makes the rotation angle control more convenient.

[0019] like Figure 1 , 2As shown, the sprayer includes a vertically downward spray pipe 12 fixed to the slider 9. The spray pipe 12 sprays the inner wall of the transport vehicle compartment. The bottom of the spray pipe 12 is connected to an inwardly inclined pipe 13, which can spray the floor of the compartment. The two sprayers have symmetrical inclined pipes 13, which can achieve spraying without dead angles. Several atomizing nozzles 14 are installed on the outside of the inclined pipe 13 and the spray pipe 12.

[0020] like Figure 1 As shown, the liquid supply system includes a storage tank 1 for holding the release agent. The outside of the storage tank 1 is pressurized by a pressure pump 2 and transported along the delivery pipe 3. The outlet of the delivery pipe 3 is connected to the inlet of the corresponding spray pipe 12 through two connecting hoses 15. A control valve 4 is installed on the delivery pipe 3.

[0021] like Figure 1 As shown, a rotary motor 7 is installed on the outside of the support column 5, and the main shaft of the rotary motor 7 is driven by the rotating frame 6.

[0022] like Figure 1 , 2 As shown, a laser beam 16 is installed on the side of the support column 5. The laser beam 16 can be on the same longitudinal plane as the sprayer. When the transport vehicle moves away from the laser beam 16, the sprayer will stop spraying to avoid waste of the release agent. The laser beam 16 is electrically connected to the controller 17. The controller 17 is electrically connected to the pressure pump 2, the rotary motor 7, and the regulating motor 11. The controller 17 is also electrically connected to the sound alarm installed on its top.

[0023] The implementation principle of the road asphalt material release agent spraying device in this application embodiment is as follows:

[0024] Before the transport vehicle 18 is loaded with asphalt, the spray pipe 12 of the sprayer is in a horizontal position (e.g., Figure 3 As shown), when the anti-sticking release agent is sprayed, the transport vehicle 18 travels to the laser beam 16. After the laser beam 16 senses the transport vehicle 18, it transmits the signal to the controller 17 and delays for 10-15 seconds (the controller 17 has a built-in delay device for automatic control). During this delay, the transport vehicle 18 continues to move forward to be level with the storage box 1 and then stops.

[0025] After the delay expires, the controller 17 controls the rotary motor 7 to rotate counterclockwise to rotate the rotating frame 6 to a vertical position. At this time, the sprayer at the bottom of the rotating frame 6 is inside the compartment of the transport vehicle 18. After the rotary motor 7 is activated, it sends a signal to the controller 17. The controller 17 controls the start of the pressurizing pump 2. The pressurizing pump 2 delivers the anti-sticking release agent of the storage box 1 along the delivery pipe 3 to the connecting hose 15. It is then delivered through the two connecting hoses 15 to the spray pipe 12 and the lower inclined pipe 13 of the corresponding sprayer. The agent is sprayed onto the inner wall of the compartment of the transport vehicle 18 through the atomizing nozzle 14 on the outside of the spray pipe 12 and the inclined pipe 13. When the pressurizing pump 2 is activated, it sends a signal to the controller 17. The controller 17 controls the sound alarm at the top to sound. After hearing the alarm, the driver of the transport vehicle 18 starts the vehicle and slowly moves forward to spray.

[0026] When the rear of the transport vehicle 18 moves away from the laser beam 16, the laser beam 16 transmits a signal to the controller 17. The controller 17 controls the pressurization pump 2 to stop running and the rotary motor 7 to rotate 90 degrees clockwise. The rotary motor 7 drives the spray pipe 12 of the sprayer to a horizontal position for the next spraying.

[0027] When encountering vehicles of different widths, to ensure uniform spraying, the distance between the lower sprayers of the two sliders 9 can be adjusted to better adapt to the different widths of the transport vehicle 18 compartment. When adjusting the sprayer distance, the operator manually operates the controller 17. When the controller 17 controls the rotary motor 7 to rotate forward, the threaded rod 10 drives the two sliders 9 in the slide rail 8 to move inward synchronously, making the distance between the lower sprayers of the sliders 9 smaller. When the controller 17 controls the rotary motor 7 to rotate in reverse, the threaded rod 10 drives the sprayers of the lower sliders 9 to move outward through the threaded transmission, thereby increasing the distance between the two sprayers. After adjustment, the distance between the spray pipe 12 of the sprayer and the inner wall of the transport vehicle 18 compartment should be 30-40cm.
