Description

Technical Field

[0001] This utility model relates to the field of concrete road maintenance, and in particular to a film covering device for concrete road maintenance. Background Technology

[0002] The main functions of mulching in concrete road maintenance include moisture retention, water retention, and inhibition of micro-cracks. Therefore, after pouring and leveling, the mulch film should be covered on the road surface in a timely manner to reduce the rapid evaporation of moisture and prevent the formation of micro-cracks.

[0003] According to the patent document with publication number CN223074566U, the protective film roll is installed between two movable frame components. In addition, the distance between the two movable frame components can be adjusted according to the width of the road surface. Then, the push-pull rod assembly pulls the entire device to move and complete the protective film covering operation.

[0004] The patent document describes a problem with the installation of a curing membrane on concrete roads. The surface of freshly poured concrete is relatively soft, and the mobile frame assembly described in the document moves across the concrete surface using wheels. During this process, the wheels can sink into the concrete, rendering the entire device immobile. Furthermore, the device leaves marks on the concrete surface during movement, and the lack of a proper leveling structure affects the smoothness of the road surface after curing. Additionally, at the end of the covering process, the curing membrane needs to be torn off and reapplied. Moreover, at the beginning of the covering process, additional personnel are required to ensure the membrane is laid smoothly. The entire process is cumbersome and requires multiple people to work together. Utility Model Content

All electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1-9 As shown, a mulching device for concrete road maintenance includes a laying mechanism 1, a cutting mechanism 2, and a driving mechanism 3. The cutting mechanism 2 is located behind the laying mechanism 1, and the driving mechanism 3 is located in the middle of the cutting mechanism 2.

[0032] In this embodiment: the laying mechanism 1 includes a laying frame 11. Support bolts 12 are threaded onto both sides of the lower end of the laying frame 11. Two leveling arms 13 are fixed to the inner side of each laying frame 11. A sliding frame 14 is slidably connected to the lower end of each leveling arm 13. The lower ends of the two sliding frames 14 are fixed to the top of a scraping plate 16. A vibration pump 17 is fixed to the middle of the top of the scraping plate 16. A leveling spring 15 is fixed to the side of each sliding frame 14 that is far apart from each other. The upper end of the leveling spring 15 is fixed to the leveling arm 13. At the lower end, a bearing is fixed to one end of the laying frame 11 through the support bolt 12. The roll of curing film is fixed to the lower end of the laying frame 11 by the two support bolts 12. At the same time, the support of the leveling arm 13 and the sliding frame 14 allows the scraper plate 16 to adhere to the poured concrete. Then, the vibration pump 17 is started to generate vibration on the scraper plate 16, which then pulls the laying frame 11 to move the entire device and level the concrete surface it passes through, reducing the generation of scratches on the concrete surface during film covering.

[0033] In this embodiment: the cutting mechanism 2 includes a cutting arm 21, a flipping bracket 22 rotatably connected to the lower end of the cutting arm 21, a pressure roller 24 rotatably connected to the front side of the flipping bracket 22, a cutting spring 23 fixed at the top of the flipping bracket 22 near the pressure roller 24, a purge seat 25 rotatably connected to the rear side of the flipping bracket 22, a cutter 26 fixed at the rear end of the purge seat 25, an air connector 27 fixed at the top of the purge seat 25, a purge air groove 4 opened inside the purge seat 25, and an adsorption groove 5 communicating with the purge air groove 4 opened at the rear side of the purge seat 25. The cutting arm 21 is fixed to the rear side of the laying frame 11, and horizontal shafts are fixed on the sides of the lower ends of the cutting arm 21 that are close to each other. The two horizontal shafts are located at the upper sides of both ends of the purge seat 25. The rotatable connection allows for the opening of a film suction port at the rear end of the blow-off seat 25, located below the cutter 26. The film suction port is connected to the adsorption tank 5. The laying frame 11 drives the cutting arm 21 to move on top of the concrete. At the same time, the pressure roller 24 on the front side of the cutting arm 21 rolls the curing film laid on the concrete, thereby removing the air between the curing film and the concrete. Meanwhile, compressed air is connected to the air connector 27 at the bottom of the blow-off seat 25 through an air pipe. The compressed air enters the blow-off air channel 4 inside the blow-off seat 25 from the air connector 27. The compressed air entering the blow-off air channel 4 is blown out from the lower end of the blow-off seat 25 and blown onto the covered curing film, thereby making the curing film adhere more closely to the concrete surface.

[0034] In this embodiment: the drive mechanism 3 includes a second support rod 32, which is fixed inside the flipping bracket 22. A first support rod 31 is fixed at the top of the second support rod 32 near the purge seat 25. A rod frame 33 is fixed inside the cutting arm 21 near the flipping bracket 22. A limiting tube frame 34 is provided above the rod frame 33. A steel wire rope 35 is fixed at the lower side of the front end of the purge seat 25. The end of the steel wire rope 35 away from the purge seat 25 runs sequentially from the first support rod 31, the second support rod 32, the rod frame 33, and the limiting tube frame 34. The steel wire rope 35 passes through the pipe support 34, and a pull rod 36 is fixed to the upper end of the steel wire rope 35. Both ends of the limiting pipe support 34 are fixed to the inner side of the laying frame 11. A guide tube for the upper end of the steel wire rope 35 to pass through is fixed in the middle of the limiting pipe support 34. An L-shaped groove is opened at the upper end of the laying frame 11 at the position of the pull rod 36. Both ends of the pull rod 36 are slidably connected in the L-shaped groove. After the curing film is laid, the pull rod 36 is pulled to slide in the L-shaped groove of the laying frame 11. At the same time, the steel wire rope 35 will follow the pull rod 36 from the first pipe support 34. The rod 31, the second support rod 32, the rod frame 33, and the limiting tube frame 34 slide. At this time, the wire rope 35 pulls the lower end of the blow-off seat 25 to rotate upward around the horizontal axis of the cutting arm 21. When the blow-off seat 25 rotates to its front side and is in contact with the lower end of the wire rope 35, the blow-off seat 25 stops rotating. At the same time, as the wire rope 35 continues to be pulled, the wire rope 35 is located at the position of the first support rod 31 and the second support rod 32 and no longer slides with the pull rod 36. Instead, the wire rope 35 is located at the position of the rod frame 33 and the limiting tube frame 34. As the lever 36 continues to move, the front end of the flipping bracket 22 will drive the pressure roller 24 to flip upward around the lower end of the cutting arm 21. At this time, the rear end of the flipping bracket 22 will drive the blowing seat 25 to flip downward, so that the cutter 26 at the rear end of the blowing seat 25 presses on the curing film that needs to be cut. At the same time, the compressed air through the blowing air duct 4 will cause the suction at the adsorption duct 5 to be generated, which will then suck up the cut end of the curing film, preventing the curing film from continuing to adhere to the concrete surface, thus facilitating the next laying.

[0035] Working principle: In use, the curing film roll is first fixed to the lower end of the laying frame 11 using two support bolts 12. Simultaneously, the leveling arm 13 and sliding frame 14 support the screed plate 16 to adhere to the poured concrete. Then, the vibration pump 17 is started to vibrate the screed plate 16, which pulls the laying frame 11, moving the entire device to level the concrete surface and reduce scratches. The curing film is then unwound from the roll and laid on the concrete. Finally, the laying frame 11 drives the cutting arm. 21 moves on top of the concrete, and at the same time, the pressure roller 24 on the front side of the support arm 21 will roll the curing film laid on the concrete to remove the air between the curing film and the concrete. Meanwhile, compressed air is connected to the air connector 27 at the bottom of the blower seat 25 through the air pipe. At this time, the compressed air will enter the blower air channel 4 inside the blower seat 25 from the air connector 27. The compressed air that enters the blower air channel 4 will be blown out from the lower end of the blower seat 25 and blown on the covered curing film, so that the curing film and the concrete surface are more closely attached.

[0036] After the curing film is laid, the pull rod 36 slides within the L-shaped groove of the laying frame 11. Simultaneously, the steel wire rope 35 follows the pull rod 36, moving along the first support rod 31, the second support rod 32, the frame 33, and the limiting tube frame 34. At this time, the steel wire rope 35 pulls the lower end of the blow-off seat 25, causing it to rotate upwards around the horizontal axis of the cutting arm 21. When the blow-off seat 25 rotates to its front side and is in contact with the lower end of the steel wire rope 35, the blow-off seat 25 stops rotating. Simultaneously, as the steel wire rope 35 continues to be pulled, it is positioned at the first support rod 31 and the second support rod 32, no longer following the pull rod 36. 6. Slide, while the steel wire rope 35 continues to move with the pull rod 36 at the position of the rod 33 and the limiting tube frame 34. At this time, the front end of the flipping bracket 22 will drive the pressure roller 24 to flip and lift upward with the lower end of the cutting arm 21 as the center. At this time, the rear end of the flipping bracket 22 will drive the blowing seat 25 to flip downward, so that the cutter 26 at the rear end of the blowing seat 25 presses on the curing film that needs to be cut. At the same time, the compressed air through the blowing air trough 4 will cause the suction at the adsorption trough 5 to be generated, and then suck up the end of the cut curing film to prevent the curing film from continuing to stick to the concrete surface, thus facilitating the next laying.

[0037] Furthermore, when re-laying is required, the tie rod 36 is removed from the upper end of the L-shaped groove of the laying frame 11, and the tie rod 36 is slid along the L-shaped groove to its lower end. At this time, the cutting spring 23 will push the flipping bracket 22 to flip its front end downward first, thereby pressing the pressure roller 24 onto the curing film. After the cutting spring 23 is fully extended, the horizontal shaft is supported on the upper side of both ends of the blowing seat 25. Due to the action of gravity, the lower end of the blowing seat 25 will flip downward around the horizontal shaft and pull the steel wire rope 35. At the same time, the curing film adsorbed on the back side of the blowing seat 25 gradually passes through the suction port and is blown onto the concrete by the compressed air blown out from the lower end of the blowing seat 25.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
