[0022] Example 2:

[0023] Based on Embodiment 1, a cleaning mechanism 5 is installed on the back of the support plate 3. The cleaning mechanism 5 includes a groove plate 501, with an insert plate 502 slidably connected inside the bottom end of the groove plate 501. The insert plate 502 is used to fix the horizontal plate 503. The bottom end of the insert plate 502 is fixedly connected to the horizontal plate 503, which is used to fix the scraper 504. The scraper 504 is fixedly connected to the inner side of the horizontal plate 503 and is used to clean the sand and gravel adhering to the outer wall of the pressure roller 1.

[0024] By setting up the cleaning mechanism 5, the sand and gravel adhering to the outer wall of the pressure roller 1 can be scraped off and stored in the groove opened at the top of the scraper 504. The collected sand and gravel can be discharged to the rear end of the pressure roller 1 through the discharge port opened on the left side of the scraper 504, so that the pressure roller 1 can flatten the sand and gravel that have been spilled on the road surface again.

[0025] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0026] When the road construction roller is put into use, the user drives the vehicle to the back of the roller 1. Then, the user loosens the first fastening bolt 405 in the fixing mechanism 4, thereby releasing the clamping of the first fastening bolt 405 on the slider 402, allowing the slider 402 to slide on the outer wall of the top plate 401. Then, the user turns the handwheel 406, which drives the gear 407 to rotate simultaneously. When the gear 407 rotates, it drives the rack meshed on its outer side to move in the opposite direction, thereby driving the first horizontal... The first horizontal bar 409 and the second horizontal bar 411 move, and through the operation of the first horizontal bar 409 and the second horizontal bar 411, the slider 402 can be driven to slide on the outer wall of the top plate 401, thereby adjusting the distance between the two sliders 402. After adjusting the distance between the two sliders 402, the user retightens the first fastening bolt 405 to fix the slider 402. Then, the user unscrews the fastening nut threaded to the outer wall of the fastening screw 404, connects the fixing block 403 to the rear end of the construction machinery body, and re-threads the fastening nut. The outer wall of the fastening screw 404 is connected to the pressure roller 1. Through the operation of the fixing block 403, the pressure roller 1 can be connected to the rear end of the construction vehicle body, allowing the pressure roller 1 to be assembled to the rear end of different specifications of work vehicles, facilitating the flattening of the road surface. When the pressure roller 1 flattens the road surface, sand and gravel will adhere to its outer wall. Through the operation of the scraper 504 in the cleaning mechanism 5, the sand and gravel adhering to the outer wall of the pressure roller 1 can be scraped off and collected into the groove opened inside the top of the scraper 504. Through the operation of the discharge port, the collected sand and gravel can be reused. The material is discharged onto the road surface, making it easier for the pressure roller 1 to flatten it again. If the front surface of the scraper 504 does not fit tightly against the back of the outer wall of the pressure roller 1, the user can loosen the second fastening bolt 505 threaded to the bottom of the outer wall of the trough plate 501, so that the insert plate 502 can be inserted into the trough plate 501. The insert plate 502 will drive the horizontal plate 503 to move. When the horizontal plate 503 moves, it can drive the scraper 504 to move simultaneously, so that the front end of the scraper 504 fits tightly against the back of the outer wall of the pressure roller 1. Then, the second fastening bolt 505 can be tightened again.
