[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4 , the utility model provides a technical solution:

[0026] A road leveling device for roadbed and pavement construction comprises a body 1, a scraper 2 is movably connected to the front end of the body 1, a push block 21 is fixedly connected to the middle of the scraper 2, a soil rolling assembly 3 is arranged inside the scraper 2, and the soil rolling assembly 3 comprises a spiral rod 31 movably connected to both ends of the scraper 2, one end of the two spiral rods 31 close to the push block 21 is fixedly connected to a second bevel gear 311, and the spiral rod 31 passes through the push block 21, a cavity 211 is provided inside the push block 21, a second rotating rod 32 is movably connected inside the cavity 211, a second driven gear 321 is fixedly connected to the lower end of the second rotating rod 32, and the upper end of the second rotating rod 32 A first driven gear 322 is fixedly connected, a first rotating rod 33 is movably connected to the upper end of the cavity 211, a first bevel gear 331 is fixedly connected to the outer middle of the first rotating rod 33, a motor 4 is arranged in the inner middle of the body 1, a first driving gear 41 is fixedly connected to the left end of the motor 4 and the left end of the first bevel gear 331, a synchronous belt 34 is movably connected between the two first driving gears 41, and the synchronous belt 34 passes through the cavity 211, the two second bevel gears 311 are meshed with the second driven gear 321, the first driven gear 322 is meshed with the first bevel gear 331, and both sides of the front end of the push block 21 have an inclination angle.

[0027] By adopting the above technical solution, when performing road construction and leveling work, the device is moved forward along the construction road, and the lower end of the scraper 2 scrapes up excess soil blocks on the road surface. At this time, the output shaft of the motor 4 rotates, so that the output shaft of the motor 4 rotates with the first driving gear 41, and the first driving gear 41 rotates through the synchronous belt 34 to drive the first driving gear 41 in the cavity 211 to rotate, and the first driving gear 41 in the cavity 211 rotates to rotate with the first rotating rod 33, and the first rotating rod 33 rotates and then drives the first bevel gear 331 to rotate, and the first bevel gear 331 rotates to rotate with the first driven gear 322, and the first driven gear The rotation axis of the wheel 322 rotates the second rotating rod 32, and the rotation of the second rotating rod 32 rotates the second driven gear 321 outside the second rotating rod 32, and the rotation of the second driven gear 321 drives the two second bevel gears 311 near the lower end of the cavity 211 to rotate, and the rotation of the two second bevel gears 311 drives the spiral rod 31 in the scraper 2 to rotate, and the rotation of the spiral rod 31 rolls the soil blocks on the left and right ends of the scraper 2 to the middle of the scraper 2. When the soil blocks pass through the pushing block 21, the soil blocks are stirred inside the scraper 2 and leveled by the scraper 2, thereby preventing the soil blocks from leaking from the two sides of the scraper 2, which greatly saves construction time.

[0028] Specifically, Figure 4As shown, square grooves 22 are provided on both sides of the inner front end of the scraper 2, and guide components 5 are provided on the left and right sides of the rear end of the scraper 2. The guide components 5 include fixed shafts 51 fixedly connected to the left and right sides of the rear end of the scraper 2, and the two fixed shafts 51 are movably connected to the outside of the baffles 52, and the two baffles 52 are movably connected to the inside of the torsion springs 511. The front ends of the two baffles 52 are fixedly connected to the middle with a protrusion 521, and the two baffles 52 are movably connected to one end of the left and right sides of the scraper 2. The elastic force of the torsion spring 511 is greater than the gravity on the baffle 52, and the two baffles 52 can be adjusted by 0 to 60 degrees through the fixed shaft 51.

[0029] By adopting the above technical scheme, when leveling the edges on both sides of the road, when the device is driven to the position of the road edge, the roller 53 close to the road edge contacts the road edge, and the device moves forward along the road edge. The forward movement of the device causes the roller 53 on the baffle 52 to move along the road edge, and the roller 53 moves in a circular motion through the fixed shaft 51, causing the baffle 52 to tilt, and the baffle 52 tilts and carries the protrusion 521 out of the square groove 22. At this time, the soil blocks inside the scraper 2 leak out backwards through the square groove 22, and the leaked soil blocks are guided to the road edge along the inclination angle of the baffle 52, so that the soil blocks are evenly guided to the road edge, which is more convenient for leveling operations. After the edge construction is completed, the device is driven away from the road edge, so that the roller 53 no longer contacts the road edge, and the baffle 52 returns to its original state through the torsion spring 511, which is convenient for the next construction operation.

[0030] Working principle: When performing road construction and leveling work, the device is moved forward along the construction road, and the lower end of the scraper 2 scrapes up the excess soil on the road surface. At this time, the output shaft of the motor 4 rotates to drive the first driving gear 41 to rotate, and the first driving gear 41 rotates through the synchronous belt 34 to drive the first driving gear 41 in the cavity 211 to rotate, and the first driving gear 41 in the cavity 211 rotates to drive the first rotating rod 33 to rotate, and the first rotating rod 33 rotates and then drives the first bevel gear 331 to rotate, and the first bevel gear 331 rotates to drive the first driven gear 322 to rotate The rotating shaft of the first driven gear 322 rotates the second rotating rod 32, and the rotation of the second rotating rod 32 rotates the second driven gear 321 outside the second rotating rod 32, and the rotation of the second driven gear 321 drives the two second bevel gears 311 near the lower end in the cavity 211 to rotate, and the rotation of the two second bevel gears 311 drives the spiral rod 31 in the scraper 2 to rotate, and the rotation of the spiral rod 31 rolls the soil blocks on the left and right ends of the scraper 2 to the middle of the scraper 2, and when the soil blocks pass through the pushing block 21, the soil blocks are stirred inside the scraper 2 and leveled through the scraper 2.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
