Description

Technical Field

[0001] This utility model belongs to the technical field of pavers, specifically relating to a paving roller spiral cleaning device. Background Technology

[0002] In the field of road construction, pavers are the core equipment for asphalt pavement laying, and the cleanliness of their paving rollers directly affects the smoothness and compaction of the pavement. In existing technologies, paving rollers are prone to adhering to sticky materials such as asphalt during continuous operation, leading to the following problems:

[0003] 1. Accumulation of adhering materials: Asphalt tends to adhere to the surface of the paving roller at high temperatures, forming uneven accumulation and causing fluctuations in paving thickness;

[0004] 2. Low cleaning efficiency: Traditional cleaning devices mostly use fixed spiral blades, relying on the contact and rotation between the spiral blades and the paving roller to scrape off the attached materials. However, due to the rigid connection, the spiral blades are difficult to fit tightly against the roller surface, resulting in limited effectiveness in scraping off stubborn attachments.

[0005] 3. High maintenance costs: Increased frequency of manual cleaning and extended downtime significantly reduce construction efficiency.

[0006] In summary, there is an urgent need for a paver self-cleaning device that is simple in structure, fits tightly, can thoroughly remove stubborn deposits, and leaves no blind spots in cleaning, in order to improve construction quality and reduce maintenance costs. Utility Model Content

[0007] This utility model aims to provide a self-cleaning device for a paver auger, which enhances the cleaning effect and eliminates residual dead corners through the synergistic effect of the scraping device, the elastic adjustment mechanism and the auger blades.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a paving roller spiral cleaning device, comprising a cleaning roller, on which two sets of spiral blades are provided, the two sets of spiral blades being symmetrically arranged with the midpoint of the cleaning roller as the center, the spiral directions of the two sets of spiral blades being opposite, and the top ends of the spiral blades being attached to the paving roller; a scraping device is provided on the cleaning roller, the scraping device comprising a side scraper and a center scraper, the side scraper being located in the gap between two adjacent spiral blades, the side scraper extending radially along the cleaning roller, the end of the side scraper abutting against the surface of the paving roller; the center scraper being located between the two sets of spiral blades, the center scraper extending radially along the cleaning roller, the end of the center scraper abutting against the surface of the paving roller; roller shafts are provided at both ends of the cleaning roller, and a paver connecting mechanism is connected to the roller shafts at both ends; the paver connecting mechanism comprises a bearing seat and a fixed bearing, the bearing seat being sleeved on the outside of the fixed bearing, bearing seat holes being provided on both sides of the bearing seat, the bearing seat holes being aligned with the bearing holes, the bearing seat being sleeved on the roller shaft, and the roller shaft passing through the bearing holes.

[0009] Furthermore, the side scrapers are arranged sequentially on both sides of the cleaning roller with the central axis of the cleaning roller as the axis.

[0010] Furthermore, an elastic adjustment mechanism is connected between the scraping device and the cleaning roller. The elastic adjustment mechanism includes an elastic telescopic groove, an anti-detachment bottom plate, an anti-detachment block, and a spring. The elastic telescopic groove is opened at the bottom of the scraping device, and one end of the spring is connected to the bottom of the elastic telescopic groove. The other end of the spring is connected to the anti-detachment bottom plate, which is slidably connected in the elastic telescopic groove. The scraping device is connected to the anti-detachment bottom plate and extends out of the elastic telescopic groove. An anti-detachment block is provided at the opening of the elastic telescopic groove, and the lower side of the anti-detachment block abuts against the anti-detachment bottom plate.

[0012] Furthermore, the paver connection mechanism also includes a mounting base plate and mounting bolts. The mounting base plate is located at the bottom of the bearing seat, and bolts are connected to the mounting base plate for connecting the cleaning roller to the paver.

[0013] Furthermore, the scraping device is made of stainless steel.

[0014] Furthermore, the ends of the side scraper and the center scraper are designed with beveled cuts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In the elastic adjustment mechanism, the spring continuously applies elastic force, pushing the side scraper and the center scraper to fit tightly against the outer wall of the paving roller. Even if there are slight unevenness or deformation on the roller surface, a constant contact pressure can still be maintained, effectively scraping away stubborn asphalt deposits that are difficult to remove with traditional spiral blades, thus improving cleaning efficiency. The left and right sets of spiral blades adopt an anti-spiral design, pushing the deposits towards the center of the roller surface, while the scraping devices are distributed at intervals along the axial direction of the self-cleaning roller, covering the gap area between the spiral blades, eliminating cleaning dead corners, and ensuring that the roller surface is clean all around.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-3 As shown, a paving roller spiral cleaning device includes a cleaning roller 1 with two sets of spiral blades 2. The two sets of spiral blades 2 are symmetrically arranged with the midpoint of the cleaning roller 1 as the center. The spiral directions of the two sets of spiral blades 2 are opposite, and the top of the spiral blades 2 are attached to the paving roller 14. The spiral blades 2 on the left are left-handed and the spiral blades 2 on the right are right-handed. When the cleaning roller 1 rotates, it can push the attached material from both ends of the paving roller 14 towards the center to avoid the accumulation of the attached material.

[0023] The cleaning roller 1 is equipped with a scraping device, which includes a side scraper 3 and a center scraper 4. Both the side scraper 3 and the center scraper 4 are made of stainless steel. The ends of both the side scraper 3 and the center scraper 4 are designed with beveled ends to make it easier to scrape off accumulated material. The side scraper 3 is located in the gap between two adjacent spiral blades 2. The side scraper 3 extends radially along the cleaning roller 1, and the end of the side scraper 3 abuts against the surface of the paving roller 14. The side scrapers 3 are arranged sequentially on both sides of the cleaning roller 1 with the central axis of the cleaning roller 1 as the axis. The axial spacing between two adjacent side scrapers 3 is the same. The side scrapers 3 cover the gap area between the spiral blades 2, eliminating cleaning dead corners and ensuring that the surface of the paving roller 14 is clean all around. The center scraper 4 is located between two sets of spiral blades 2. The center scraper 4 extends radially along the cleaning roller 1, and the end of the center scraper 4 abuts against the surface of the paving roller 14. The length of the center scraper 4 is slightly less than the distance between the left and right sets of spiral blades 2. The center scraper 4 is used to scrape off the attached material pushed towards the center of the paving roller 14 by the spiral blades 2 on both sides.

[0024] The cleaning roller 1 has roller shafts 5 at both ends. A paver connection mechanism is connected to the roller shafts 5 at both ends. The paver connection mechanism includes bearing seats 6, fixed bearings 7, mounting base plates 8, and mounting bolts 9. The bearing seats 6 are sleeved on the outside of the fixed bearings 7. Two fixed bearings are installed in the bearing seats 6. The two fixed bearings are arranged side by side to increase the stability of the cleaning roller. The bearing seats 6 have bearing seat holes on both sides. The bearing seat holes are aligned with the bearing holes. The bearing seats 6 are sleeved on the roller shafts 5. The roller shafts 5 pass through the bearing holes. The mounting base plates 8 are located at the bottom of the bearing seats 6. Bolts are connected to the mounting base plates 8 for connecting the cleaning roller 1 to the paver.

[0025] An elastic adjustment mechanism is connected between the scraping device and the cleaning roller 1. The elastic adjustment mechanism includes an elastic telescopic groove 10, an anti-detachment base plate 11, anti-detachment blocks 12, and a spring 13. The elastic telescopic groove 10 is located at the bottom of the side scraper 3 and the center scraper 4. One end of the spring 13 is connected to the bottom of the elastic telescopic groove 10, and the other end of the spring 13 is connected to the anti-detachment base plate 11. The anti-detachment base plate 11 is slidably connected within the elastic telescopic groove 10. The side scraper 3 or the center scraper 4 is connected to the anti-detachment base plate 11, and the side scraper 3 or the center scraper 4 extends out of the elastic telescopic groove 10. Two anti-detachment blocks 12 are provided at the opening of the elastic telescopic groove 10. The length of the anti-detachment base plate 11 is greater than the gap between the two anti-detachment blocks 12. The spring 13 in the elastic scraping device continuously pushes the anti-detachment base plate 11 upward, so that the ends of the side scraper 3 and the center scraper 4 press tightly against the outer wall of the paving roller 14. The beveled cut design of the side scraper 3 and the center scraper 4 reduces scraping resistance. During the rotation of the paving roller 14, they work together with the spiral blades to thoroughly scrape away stubborn attachments. The lower side of the anti-detachment block 12 abuts against the anti-detachment base plate 11 to prevent the side scraper 3 or the center scraper 4 from detaching from the elastic expansion groove 10 due to vibration or impact.

[0026] In use, the paver connecting mechanism is installed on the roller shafts 5 at both ends of the cleaning roller 1. The bearing seats 6 are fitted onto the outside of the roller shafts 5. The bearing seats 6 are symmetrically fixed in the preset positions of the paver using the mounting bolts 9 on the mounting base plate 8. The installation height of the bearing seats 6 is adjusted to ensure that the ends of the spiral blades 2 on both sides of the cleaning roller 1, the side scrapers 3, and the center scraper 4 are all in close contact with the outer wall of the paving roller 14. When the paving roller 14 rotates, the spiral blades 2 on both sides rotate synchronously with the self-cleaning roller 1. The spiral blades 2 on the left side are left-handed and the spiral blades 2 on the right side are right-handed. Both push the attached material from both ends of the paving roller 14 towards the center, preventing material accumulation. The spring 13 of the elastic adjustment mechanism continuously pushes the anti-detachment base plate 11 upwards, causing the ends of the side scraper 3 and the center scraper 4 to press tightly against the outer wall of the paving roller 14. The beveled cut design of the side scraper 3 and the center scraper 4 reduces scraping resistance. During the rotation of the paving roller 14, they work together with the spiral blades 2 to thoroughly scrape away stubborn deposits. The anti-detachment block 12 limits the displacement range of the anti-detachment base plate 11, preventing the side scraper 3 and the center scraper 4 from detaching from the elastic expansion groove 10 due to vibration or impact. During the operation of the paving roller 14, the spiral blades and the elastic scraping device together cover the entire circumference of the roller surface, eliminating the dead angles of traditional spiral blades. Through the elastic compensation of the spring 13, the side scraper 3 and the center scraper 4 adapt to the slight deformation of the paving roller 14 surface, ensuring constant cleaning pressure.
