[0044] Example

[0045] like Figure 1 , Figure 2 and Figure 4As shown in the figure, this utility model embodiment provides a bentonite waterproof blanket spreading and compaction device, including a drive component, a support component 1, a compaction wheel 2, a mounting component 3, and a guide component. The drive component provides the moving power for the blanket spreading and compaction device and may include a motor, enabling the device to move on the spreading surface to complete the spreading and compaction of the waterproof blanket. The support component 1 is mounted on the drive component and provides support for mounting and supporting other components. The compaction wheel 2 is mounted on the support component 1, and the drive component drives the compaction wheel 2 to roll on the spreading surface to complete the compaction of the waterproof blanket. The rolling of the compaction wheel 2 is synchronized with the power output of the drive component, ensuring that the waterproof blanket is compacted simultaneously with spreading. The rolling compaction of the compaction roller 2 ensures a tight bond between the waterproof blanket and the paved surface, improving the waterproofing effect. For example, the compaction roller 2 can be a rolling drum structure. The mounting member 3 is mounted on the support member 1 to install and support the waterproof blanket member 4, ensuring the stability of the waterproof blanket during the paving process. The guide member is mounted on the support member 1 and can guide the waterproof blanket member 4 on the mounting member 3 to the underside of the compaction roller 2. That is, the mounting member 3 is mounted on the support member 1 and works in conjunction with the guide member to guide the waterproof blanket member 4 to the underside of the compaction roller 2. The compaction roller 2 is configured to spread and compact the waterproof blanket member 4 on the paved surface by rolling when the paving and compaction device is driven to move.

[0046] For example, such as Figure 3 As shown, the driving component includes a roller 5, which can be driven by a motor to rotate. The roller 5 is configured to drive the blanket spreading and compacting device to move by rotating. The rotation of the roller 5 causes the waterproof blanket spreading and compacting device to roll and move on the paving surface. After the spreading and compacting device is driven, the compaction wheel 2 achieves the spreading and compaction of the waterproof blanket by rolling. In a preferred embodiment of this utility model, the driving component further includes a rod, a first transmission gear chain 7, and a second transmission gear chain 8. The rod includes a driving rod 9, a first gear disc 10, and a second gear disc 11, with the first gear disc 10 and the second gear disc 11 respectively disposed at both ends of the driving rod 9. The rolling component 5 includes a first roller 12 and a second roller 13. A third gear disc 14 is disposed on the first roller 12, and a fourth gear disc 15 is disposed on the second roller 13. The first gear disc 10 and the third gear disc 14 are respectively meshed and linked at both ends of the first transmission gear chain 7, and the second gear disc 11 and the fourth gear disc 15 are respectively meshed and linked at both ends of the second transmission gear chain 8. The driving rod 9 is configured to be driven by a motor to rotate and drive the first gear disc 10 and the second gear disc 11 to rotate. The rotation of the first gear disc 10 is configured to drive the third gear disc 14 to rotate through the first transmission gear chain 7, thereby causing the first roller 12 to roll. The rotation of the second gear disc 11 is configured to drive the fourth gear disc 15 to rotate through the second transmission gear chain 8, thereby causing the second roller 13 to roll.

[0047] Specifically, the motor, as a power source, is connected to the drive rod 9. The drive rod 9 is part of a rod and can be driven to rotate by the motor. The two ends of the drive rod 9 are respectively connected to the first gear plate 10 and the second gear plate 11. The first transmission gear chain 7 connects the first gear plate 10 and the third gear plate 14 on the first roller 12. The second transmission gear chain 8 connects the second gear plate 11 and the fourth gear plate 15 on the second roller 13. The rotation of the first gear plate 10 is transmitted to the third gear plate 14 through the first transmission gear chain 7, causing the first roller 12 to roll. The rotation of the second gear plate 11 is transmitted to the fourth gear plate 15 through the second transmission gear chain 8, causing the second roller 13 to roll. In operation, after the motor starts, the drive rod 9 rotates, causing the first toothed disc 10 and the second toothed disc 11 at both ends of the drive rod 9 to rotate accordingly. The rotation of the first toothed disc 10 is transmitted to the third toothed disc 14 through the first transmission chain 7, driving the first roller 12 to roll. Similarly, the rotation of the second toothed disc 11 is transmitted to the fourth toothed disc 15 through the second transmission chain 8, driving the second roller 13 to roll. During this process, the rolling of the first roller 12 and the second roller 13 moves the entire paving and compaction device across the paving surface, and the compaction wheel 2 completes the paving and compaction of the waterproof blanket. This structure, by precisely controlling the motor speed, can adjust the moving speed of the paving and compaction device, thereby controlling the paving speed and compaction quality. The movement and compaction actions of the device are driven by the motor, reducing manual operation, lowering labor intensity, improving construction safety, and enabling the device to achieve continuous paving and compaction actions, thus improving construction efficiency.

[0048] In this embodiment of the utility model, the waterproof blanket 4 is placed on the paving and compaction device, and the paving vehicle is driven forward by the motor. The guide guides the end of the waterproof blanket into the compaction wheel 2 of the paving and compaction device. Under the rotation of the first roller 12 and the second roller 13 on the rear side, the paving and compaction device drives the waterproof blanket forward to spread it. Under the action of the compaction wheel 2, the waterproof blanket can be made to fit with the ground, and the overlap quality between the waterproof blankets can be guaranteed.

[0049] It should be noted that, to improve the stability of the device, the third gear 14 can be positioned at its center, and the fourth gear 15 at its center. This improves transmission stability. The third gear 14 and the first roller 12 can be integrally formed, or they can be connected by bonding, snap-fitting, or threaded connections; no limitation is made here. Similarly, the fourth gear 15 and the second roller 13 can also be integrally formed, or they can be connected by bonding, snap-fitting, or threaded connections; no limitation is made here, as long as sufficient connection strength is achieved. Of course, in other embodiments, only one, three, or four rollers can be provided; no limitation is made here. Returning to this embodiment, the first roller 12 and the second roller 13 are located on both sides of the mounting component 3, which improves the stability of the device. Preferably, the distance between the first roller 12 and the second roller 13 is greater than or equal to the width of the waterproof blanket component 4, thus preventing the first roller 12 and the second roller 13 from contacting or crushing the laid waterproof blanket component 4 during construction. To improve the quality of paving and compaction by the compaction roller 2, the compaction roller 2 can be configured to have the same length as the width of the waterproof blanket 4. This will increase the contact area between the compaction roller 2 and the waterproof blanket 4, thereby improving the quality of paving and compaction.

[0050] Furthermore, a protective cover 16 is provided above the drive rod 9. The protective cover 16 is connected to the support component 1. A motor is installed inside the protective cover 16 and is connected to the drive rod 9. The first roller 12 and the second roller are connected through a connecting rod 18. The protective cover 16 is located inside the connecting rod 18. Specifically, the function of the protective cover 16 is to protect the motor and drive rod 9 inside the device, preventing dust, moisture, and other external factors that may affect the performance of the equipment from entering. The motor is fixed inside the protective cover 16 to provide power for the rotation of the drive rod 9. The protective cover 16 is located inside the connecting rod 18, reducing the footprint of the device and making the device more compact. At the same time, the connecting rod 18 provides additional protection for the protective cover 16. The first roller 12 and the second roller 13 are connected through the connecting rod 18, which can ensure that the two rollers rotate synchronously and maintain the stability and uniformity of the paving and compaction device. It should be noted that the protective cover 16 can also serve as a counterweight, which can improve the stability of the device operation.

[0051] In a preferred embodiment of this utility model, the support member 1 includes a horizontal member 6 and a vertical member 17. A protective cover 16 is disposed inside the horizontal member 6 and the vertical member 17, and the vertical member 17 is vertically connected to the horizontal member 6. Both ends of the drive rod 9 penetrate the protective cover 16 and the vertical member 17. The first gear plate 10 and the second gear plate 11 are both disposed outside the vertical member 17. The horizontal member 6 and the vertical member 17 improve the stability and support of the device. The protective cover, disposed inside the horizontal member 6 and the vertical member 17, provides comprehensive protection for the motor and the drive rod 9, while reducing the impact of the external environment on the internal components of the device. The drive rod 9 has protective covers 16 at both ends to ensure that the power of the motor can be smoothly transmitted to both ends of the drive rod 9. The drive rod 9 also has vertical rods 17 at both ends, so that the drive rod 9 can be fixed on the bracket 1, while allowing the drive rod 9 to rotate. The first gear 10 and the second gear 11 are both located on the outside of the vertical rod 17, so that the gears can effectively mesh with the gears on the transmission chain and rollers, which also facilitates observation and maintenance, and reduces interference between internal components.

[0052] In this embodiment of the utility model, the mounting member 3 is connected to the vertical rod member 17. The mounting member 3 is configured to install the waterproof blanket member 4 in a roll-up manner. The mounting member 3 penetrates the core of the roll-up waterproof blanket member 4, and the roll-up waterproof blanket member 4 can be driven to rotate and then released by the plane. This ensures the stability and fixation of the waterproof blanket member 4 during the paving process. The vertical rod member 17, as part of the support member 1, provides the necessary support and fixing points for the mounting member 3. The mounting member 3 penetrates the core of the roll-up waterproof blanket member 4. Exemplarily, the mounting member 3 can be configured as a single rod core around which the waterproof blanket member 4 is wound and rotated, allowing the waterproof blanket to rotate and unfold on the mounting member 3. It should be noted that the roll-up waterproof blanket member 4 can be configured to rotate relative to the mounting member 3, or the mounting member 3 can be configured to rotate around the vertical rod member 17. The main purpose is to ensure that the roll-up waterproof blanket member 4 can be unfolded smoothly, and no limitation is made here.

[0053] Further, the guide includes a first steering member 19 and a second steering member 20 mounted on the crossbar member 6. As shown in the figure, the first steering member 19 and the second steering member 20 are preferably cylindrical wheel-shaped structures. The first steering member 19 and the second steering member 20 are located on both sides of the compaction wheel 2, and the first steering member 19 and the second steering member 20 protrude laterally from the compaction wheel 2. After the waterproof blanket member 4 is released at the mounting member 3, it will change direction at the guide and extend to the bottom of the compaction wheel 2. The first steering member 19 and the second steering member 20 will contact the radial sides of the waterproof blanket member 4, respectively. Specifically, after the waterproof blanket member 4 is released at the mounting member 3, it will change direction at the guide and then extend to the bottom of the compaction wheel 2. During this process, the first steering component 19 and the second steering component 20 contact the radial sides of the waterproof blanket component 4 respectively, ensuring that the waterproof blanket component 4 moves along the predetermined path. The function of the steering components is to guide and adjust the direction of the waterproof blanket component 4, enabling it to be smoothly transferred from the mounting component 3 to the compaction roller 2, ensuring the continuity and uniformity of the paving process, reducing deviations caused by improper human operation. By precisely controlling the direction of the waterproof blanket component 4, the efficiency and quality of paving can be improved, and material waste can be reduced. The guide component is installed on the horizontal bar component 6, forming a stable frame structure with the vertical bar component 17 and the support component 1, which helps to maintain the stability of the guide component during construction.

[0054] To improve the stability of the device, a first reinforcing rib 21 can be provided on the first steering component 19, and a second reinforcing rib 22 can be provided on the second steering component 20. One end of the first reinforcing rib 21 is connected to the first steering component 19, and the other end is connected to the protective cover 16. One end of the second reinforcing rib 22 is connected to the second steering component 20, and the other end is connected to the protective cover 16. The provision of the first reinforcing rib 21 and the second reinforcing rib 22 enhances the structural strength of the first steering component 19 and the second steering component 20, and improves the stability of the guide component when subjected to the tension of the waterproof blanket. This connection method forms a stable triangular structure, increasing the rigidity and stability of the entire guidance system. Preferably, it also includes several third reinforcing ribs 23. One end of each third reinforcing rib 23 is connected to the protective cover 16, and the other end is connected to the vertical rod 17. The provision of the third reinforcing ribs 23 further enhances the connection strength between the protective cover 16 and the vertical rod 17, improving the stability and rigidity of the entire device.

[0055] To better control the direction of the paving and compaction device, a steering handle 24 can be installed on the protective cover 16. The steering handle 24 makes it easier for the operator to control the direction of travel of the paving and compaction device, improving the flexibility and efficiency of operation.

[0056] In summary, the paving and compaction device provided in this embodiment improves the overlap quality of the waterproof blanket and the adhesion between the waterproof blanket and the paved surface by simultaneously paving and compacting with a front compaction roller, thus ensuring construction quality. It guarantees the flatness and uniformity of the waterproof blanket laying, reducing errors that may occur during manual laying. Simultaneously, it allows for faster and more efficient completion of large-area waterproof blanket laying operations. Compared to traditional manual laying, it is more efficient, reduces labor costs, decreases worker workload, and improves construction safety.
