Description

Technical Field

[0001] This utility model relates to the field of paver technology, specifically to a paver device for adjusting height. Background Technology

[0002] In the fields of road engineering, municipal construction and site leveling, pavers are the core equipment for material spreading and compaction, and their performance directly affects the quality of the project and the efficiency of construction.

[0003] In existing technologies, cleaning of pressure rollers mostly relies on manual cleaning or fixed scrapers. Manual cleaning requires stopping the machine during work breaks, which is not only time-consuming and labor-intensive, but also poses safety hazards. Although fixed scrapers can clean in real time, they are mostly rigidly connected, and the fit with the pressure roller is not adjustable. Excessive squeezing can cause the scraper to wear out too quickly, or the loose fit can lead to incomplete cleaning, requiring frequent scraper replacements and increasing maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a paver device for adjusting height, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paver device for adjusting height, comprising a mounting plate, a support arm fixedly connected to the side wall of the mounting plate, a bearing plate fixedly connected to the end of the support arm, a hydraulic rod fixedly connected to the bottom end of the bearing plate, a housing fixedly connected to the bottom end of the hydraulic rod, a pressure roller rotatably connected to the inner wall of the housing, a moving assembly provided on the side wall of the housing, the moving assembly comprising a mounting frame fixedly connected to the side wall of the housing, a moving plate slidably connected inside the mounting frame, a through hole provided on the side wall of the moving plate, a screw threadedly connected to the through hole, the end of the screw rotatably connected to the inner wall of the mounting frame, a side plate fixedly connected to the bottom end of the moving plate, and a scraper assembly provided on the side wall of the side plate.

[0015] like Figures 1-3 As shown, this utility model provides a technical solution: a paver device for adjusting height, including a mounting plate 1. The side wall of the mounting plate 1 has four sets of symmetrically arranged bolt holes for bolts to pass through, and the mounting plate 1 is installed on the paver's traction equipment using bolts. A support arm 2 is fixedly connected to the side wall of the mounting plate 1, and a bearing plate 3 is fixedly connected to the end of the support arm 2. The support arm 2 and the bearing plate 3 provide a stable mounting platform for the hydraulic rod 31, bearing the weight of the hydraulic rod 31 and its lower components, and transferring the weight to the mounting plate 1 through the support arm 2.

[0016] A hydraulic rod 31 is fixedly connected to the bottom end of the bearing plate 3, and a housing 4 is fixedly connected to the bottom end of the hydraulic rod 31. A pressure roller 41 is rotatably connected to the inner wall of the housing 4. When the hydraulic rod 31 extends, it drives the housing 4 and the pressure roller 41 below it to move downward, reducing the working height; when the hydraulic rod 31 retracts, it drives the housing 4 and the pressure roller 41 below it to move upward, increasing the working height, thereby achieving precise adjustment of the paver's working height. During paver operation, the pressure roller 41 rotates to compact the paved material, making it dense and flat. The housing 4 provides rotational support and protection for the pressure roller 41. A notch 42 is provided on the side wall of the housing 4, which is used for the moving component 5 to allow the scraper component 6 to enter and exit the interior of the housing 4. A movable component 5 is provided on the side wall of the housing 4. The movable component 5 includes a mounting frame 51, which is fixedly connected to the side wall of the housing 4. A movable plate 52 is slidably connected inside the mounting frame 51. A through hole is opened on the side wall of the movable plate 52, and a lead screw 53 is threadedly connected in the through hole. The end of the lead screw 53 is rotatably connected to the inner wall of the mounting frame 51. The movable plate 52 converts the rotational motion of the lead screw 53 into its own linear sliding by threading with the lead screw 53, thereby realizing sliding inside the mounting frame 51.

[0017] A motor 54 is fixedly connected to the end face of the mounting frame 51. The output shaft of the motor 54 passes through and is rotatably connected to the side wall of the mounting frame 51. The output shaft of the motor 54 is fixedly connected to the end of the lead screw 53. The motor 54 provides the power to drive the lead screw 53 to rotate. A side plate 55 is fixedly connected to the bottom end of the moving plate 52. A scraper assembly 6 is provided on the side wall of the side plate 55. The side plate 55 is used to install the scraper assembly 6 and transmit the movement of the moving plate 52 to the scraper assembly 6, so that the scraper assembly 6 can move with the moving plate 52. The scraper assembly 6 can move closer to or away from the pressure roller 41. When the scraper assembly 6 is close to the outer wall of the pressure roller 41, it can clean the material adhering to the surface of the pressure roller 41. When the scraper assembly 6 is away from the pressure roller 41, it can avoid unnecessary wear and tear on the scraper assembly 6 and increase the service life of the scraper assembly 6.

[0018] The scraper assembly 6 includes a T-shaped rod 61, which is slidably connected to the side wall of the side plate 55. The T-shaped rod 61 serves as a guide and connector. The T-shaped structure of the T-shaped rod 61 prevents it from falling off the side wall of the side plate 55 and ensures that it can only slide axially. A horizontal plate 62 is fixedly connected to the end of the T-shaped rod 61. An arc-shaped scraper 63 is fixedly connected to the side wall of the horizontal plate 62, transmitting the movement of the T-shaped rod 61 to the arc-shaped scraper 63. It also provides mounting support for the return spring 64. Through the contact between the arc-shaped scraper 63 and the surface of the pressure roller 41, the material adhering to the surface of the pressure roller 41 is efficiently scraped off, ensuring that the pressure roller 41 is clean.

[0019] The horizontal plate 62 and the side plate 55 are elastically connected by a return spring 64. The return spring 64 is sleeved on the outer wall of the T-shaped rod 61. The return spring 64 provides elastic buffer for the horizontal plate 62, so that while the arc-shaped scraper 63 is in contact with the surface of the pressure roller 41, it will not affect the rotation of the pressure roller 41. Thus, while the pressure roller 41 is rotating, it can be thoroughly cleaned.

[0020] In this utility model, when in use, the entire device is first securely installed on the traction equipment of the paver by bolts through the four sets of symmetrical bolt holes on the side wall of the mounting plate 1, ensuring that the device is tightly connected to the traction equipment and avoiding loosening or displacement during operation.

[0021] After installation, the working height is adjusted by controlling the extension and retraction of the hydraulic rod 31 according to the actual needs of the paving operation. When it is necessary to lower the working height, the hydraulic rod 31 is extended, which moves the housing 4 and the internal pressure roller 41 downward; when it is necessary to raise the working height, the hydraulic rod 31 is retracted, which moves the housing 4 and the pressure roller 41 upward until the pressure roller 41 is adjusted to the appropriate working height position.

[0022] After the paver starts working, the pressure roller 41 rotates under the drive of the traction equipment to compact the paved material, making it dense and flat.

[0023] When it is necessary to clean the material adhering to the surface of the pressure roller 41, the motor 54 in the moving assembly 5 is activated. The output shaft of the motor 54 drives the lead screw 53 to rotate. Since the moving plate 52 is threadedly connected to the lead screw 53 and the moving plate 52 is slidably connected inside the mounting frame 51, the rotational motion of the lead screw 53 is converted into the linear sliding of the moving plate 52 along the mounting frame 51. The moving plate 52 drives the scraper assembly 6 to move synchronously through the side plate 55 fixedly connected to the bottom, so that the scraper assembly 6 enters the interior of the housing 4 through the notch 42 on the side wall of the housing 4 and gradually approaches the pressure roller 41.

[0024] As the scraper assembly 6 approaches the pressure roller 41, the arc-shaped scraper 63 gradually comes into contact with the surface of the pressure roller 41. Because the cross plate 62 and the side plate 55 are elastically connected by a return spring 64, the return spring 64 applies an elastic force to the cross plate 62, causing the arc-shaped scraper 63 to fit tightly against the surface of the pressure roller 41 without hindering its rotation. With the continuous rotation of the pressure roller 41, the arc-shaped scraper 63 efficiently scrapes away material adhering to the surface of the pressure roller 41, ensuring the cleanliness of the pressure roller 41 and preventing the adhering material from affecting the quality of subsequent compaction operations.

[0025] When cleaning is not required or maintenance of the scraper assembly 6 is needed, the control motor 54 rotates in the reverse direction, driving the lead screw 53 to rotate in the reverse direction. The moving plate 52 slides along the mounting frame 51 away from the pressure roller 41. The scraper assembly 6 moves together with the side plate 55 and exits the housing 4 through the notch 42, moving away from the pressure roller 41. This avoids unnecessary wear and tear caused by the scraper assembly 6 contacting the pressure roller 41 when not in operation, effectively extending the service life of the scraper assembly 6.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
