Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, and in particular to a concrete surface curing device. Background Technology

[0002] In the current post-concrete pouring stage, to ensure the integrity and durability of the concrete structure and prevent quality problems such as cracks, a crucial step is to perform scientific and reasonable curing. Traditionally, this involves covering the concrete surface with a protective film to maintain suitable humidity and temperature conditions, promoting full hardening and strength development.

[0003] However, current mulching operations often rely on manual labor. The specific steps include: workers manually pushing rollers loaded with curing plastic film forward slowly to ensure the film adheres to the concrete surface. In addition, to prevent the film from being blown away in windy weather, workers also need to place weight blocks on both sides of the laid film to secure it.

[0004] In summary, existing concrete curing mulching methods have significant drawbacks, mainly in their high labor intensity and low efficiency. There is an urgent need to find a more efficient and convenient solution to reduce the burden on workers. Utility Model Content

[0005] The purpose of this invention is to provide a concrete surface curing device to solve the problems of high labor intensity and low efficiency mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete surface curing device, comprising a base, wheels, and a pusher frame. The wheels are installed at the four ends below the base, and the pusher frame is installed on one side of the base. A film-coating roller is rotatably connected to the upper end of the base, and a film-pressing roller is rotatably connected to the lower end of the base. A film-passing opening is provided on the base. A storage frame is also installed on the base, containing a pressing block. An intermittent mechanism for fixing the film material is provided within the storage frame, comprising a feeding channel and a feeding roller. The feeding channel is vertically connected to the lower end of the storage frame and communicates with the storage frame to discharge the pressing block. Two feeding channels are provided and symmetrically arranged at both ends of the storage frame. A rotating shaft is coaxially fixed between the two feeding rollers, and the feeding rollers are rotatably connected to the feeding channels via the rotating shaft. A feeding groove for the pressing block to fall into is provided on the feeding roller. The intermittent mechanism also includes a drive assembly for driving the feeding rollers to rotate.

[0007] As a further embodiment of this utility model, the drive assembly includes a linkage belt, which is tensioned around the shaft of the feeding roller and the pressing roller. Through the design of the linkage belt, the linkage between the pressing roller and the feeding roller is realized, so that the pressing and releasing actions are performed simultaneously, simplifying the operation process and improving the degree of automation.

[0008] As a further embodiment of this utility model, the intermittent mechanism also includes a disturbance component, which is used to disturb the pressing blocks in the storage frame, thereby solving the problem of poor material discharge caused by the accumulation of pressing blocks in the storage frame and improving the material discharge efficiency.

[0009] As a further embodiment of this utility model, the disturbance component includes a disturbance rod, a driving component, and two levers. The two levers are vertically fixed to both ends of the disturbance rod and correspond to the two feeding channels respectively. The driving component is used to drive the disturbance rod to rotate. The rotation of the disturbance rod drives the levers to disturb the pressure block, thereby achieving effective disturbance of the pressure block and preventing the pressure block from accumulating.

[0010] As a further embodiment of this invention, the drive assembly includes a drive belt that is tensioned around the rotating shaft of the disturbance rod and the feed roller. The drive belt enables synchronous rotation of the disturbance rod and the feed roller, further simplifying the transmission structure.

[0011] As a further embodiment of this utility model, the disturbance rod is coaxially arranged with the storage frame, and the disturbance rod is rotatably connected to the storage frame. The semi-cylindrical structure of the storage frame and the coaxially arranged disturbance rod cooperate to make the disturbance effect more uniform and improve the fluidity of the briquette.

[0012] As a further embodiment of this utility model, the storage frame is a semi-cylindrical structure with an upward opening. The middle part of the storage frame is provided with an upwardly extending arc-shaped arch, which is used to guide the pressing block toward the material feeding channel. The design of the arc-shaped arch cleverly guides the pressing block to flow into the material feeding channel, reduces the jamming phenomenon of the pressing block in the feeding process, and improves the feeding efficiency.

[0013] This utility model provides a concrete surface curing device, which has the following beneficial effects:

[0014] This concrete surface curing device, through the setting of an intermittent mechanism, allows the pressure blocks to be pre-stored in the storage box during use. Workers push the base to move, and as the pressure roller rotates, the discharge roller and the disturbance rod rotate together through the linkage belt and synchronous belt to realize the intermittent lowering of the pressure blocks. This significantly improves the efficiency and convenience of concrete curing and covering operations and reduces the labor intensity of workers. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Reference Figure 1 , 2 A concrete surface curing device includes a base 1, four wheels 2, and a pusher frame 3. The four wheels 2 are respectively installed at the four ends of the lower surface of the base 1. The pusher frame 3 is fixedly installed on one side of the base 1 to facilitate the movement of the base 1 by pedestrians. A film-coating roller 4 is rotatably connected to the upper end of the base 1, and a film-pressing roller 5 is rotatably connected to the lower end of the base 1. The film-pressing roller 5 is in contact with the ground. A film-passing opening 6 is provided on the base 1 for the film material to pass through the film-passing opening 6.

[0023] The membrane roll is installed on the covering roller 4. The membrane passes through the membrane opening 6 and passes around the pressing roller 5. When the user pushes the base 1 to move on the concrete surface to be covered for curing, the membrane is covered on the concrete surface by the pressing roller 5.

[0024] Reference Figure 2 Specifically, two hinge seats 7 are symmetrically arranged on the upper surface of the base 1. U-shaped grooves 8 are opened on the two hinge seats 7. The two ends of the coating roller 4 are respectively installed in the U-shaped grooves 8 of the two hinge seats 7, so as to realize the detachable rotatable connection between the coating roller 4 and the hinge seats 7.

[0025] Reference Figure 2 , 3 A storage frame 9 is also installed on the base 1. The storage frame 9 has an upward-opening semi-cylindrical structure, and the axis of the storage frame 9 is parallel to that of the pressure roller 5. A pressure block 10 is located inside the storage frame 9. The pressure block 10 is preferably spherical, but in other embodiments, it can also be square or other structures. The storage frame 9 is provided with an intermittently lowering pressure block 10 to fix the film material.

[0026] Referring to Figures 3 and 4, the intermittent mechanism includes a feeding channel 11 and a feeding roller 12. The feeding channel 11 is vertically connected to the lower end of the storage frame 9 and communicates with the storage frame 9 to discharge the pressing blocks 10. There are two feeding channels 11, which are symmetrically arranged at both ends of the storage frame 9. The pressing blocks 10 discharged from the feeding channel 11 will be distributed at the edge of the laid film material.

[0027] Referring to Figures 3 and 5, a rotating shaft 21 is coaxially fixed between the two feeding rollers 12. The feeding rollers 12 are rotatably connected to the feeding channel 11 via the rotating shaft 21. To accommodate the size of the feeding rollers 12, the diameter of the portion of the feeding channel 11 where the feeding rollers 12 are installed is adjusted accordingly, and a certain gap is left between the inner wall of the feeding channel 11 and the feeding rollers 12. A feeding groove 13 is provided on the feeding rollers 12 for the pressing blocks 10 to fall into. The pressing blocks 10 falling into the feeding channel 11 will first enter the feeding groove 13. As the feeding rollers 12 rotate, when the feeding groove 13 rotates to the opening direction, the pressing blocks 10 are discharged under their own weight and fall onto the laid film material.

[0028] The feeding trough 13 is slightly larger than the pressing block 10. At the same time, the diameter of the feeding channel 11 located below the feeding roller 12 is larger than the size of the pressing block 10. This allows the pressing block 10 to fall smoothly into the feeding trough 13 and be discharged from the feeding channel 11.

[0029] Reference Figure 2 , 3 The intermittent mechanism also includes a drive assembly for rotating the feed roller 12. Specifically, the drive assembly includes a linkage belt 14. Linkage pulleys 15 are installed at both ends of the feed roller 12 shaft 21 and the pressure roller 5. The linkage belt 14 is tensioned between the feed roller 12 shaft 21 and the pressure roller 5 linkage pulleys 15, achieving linkage between the two. The linkage pulley 15 on the feed roller 12 shaft 21 is larger than the linkage pulley 15 on the pressure roller 5, which can extend the feeding time of the pressing block 10 and increase the distance between adjacent pressing blocks 10. Of course, in actual use, the size of the linkage pulleys 15 on the feed roller 12 shaft 21 and the pressure roller 5 can be freely adjusted according to the actual situation to meet the requirements of the gap between the pressing blocks 10.

[0030] In other embodiments, the drive assembly may also be a motor, which is mounted on the outer wall of the feeding channel 11. The motor shaft 21 is fixedly connected to the shaft 21 of the feeding roller 12, and the rotation of the feeding roller 12 is controlled by the motor.

[0031] Reference Figure 4 , 5 The intermittent mechanism also includes a disturbance component, which is used to disturb the compressed blocks 10 inside the storage box 9. The disturbance component solves the problem of poor material discharge caused by the accumulation of compressed blocks 10 inside the storage box 9, and ensures smooth material discharge of compressed blocks 10.

[0032] Reference Figure 3 , 5 The disturbance assembly includes a disturbance rod 16, a drive component, and two levers 17. The disturbance rod 16 is rotatably connected to the storage frame 9 and is coaxial with the storage frame 9. The two levers 17 are vertically fixed to both ends of the disturbance rod 16 and are respectively aligned with the two feeding channels 11. The drive component is used to drive the disturbance rod 16 to rotate. The levers 17 can be made of deformable plastic, so that in the event of an inability to be disturbed, they can continue to rotate with the disturbance rod 16 by means of deformation.

[0033] Reference Figure 4 , 5 The drive assembly includes a drive belt 18. A synchronous pulley 19 is coaxially fixed to the end of the disturbance rod 16 extending out of the storage frame 9. The drive belt 18 is wound and tensioned between the synchronous pulley 19 of the disturbance rod 16 and the linkage pulley 15 of the rotating shaft 21 of the feed roller 12, so as to realize the synchronous rotation of the two. In other embodiments, the drive assembly can also be a motor, and the disturbance rod 16 can be controlled by connecting the motor to the disturbance rod 16.

[0034] Reference Figure 5 The storage frame 9 has an upwardly extending arc-shaped arch 20 in the middle, which guides the pressing block 10 toward the feeding channel 11. This further improves the feeding efficiency and reduces the jamming phenomenon of the pressing block 10 during the feeding process.

[0035] The implementation principle of a concrete surface curing device according to an embodiment of this application is as follows:

[0036] The pressing block 10 is pre-stored in the storage box 9. The worker pushes the base 1 to move. During the rotation of the pressing roller 5, the feeding roller 12 and the disturbance rod 16 rotate together through the linkage belt 14 and the synchronous belt to realize the gap lowering of the pressing block 10.

[0037] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described.
