Description

Technical Field

[0001] The invention relates to the technical field of road rollers, and in particular to a road roller for highway reconstruction and expansion and a use method thereof. Background Art

[0002] A road roller, also known as a soil roller, is a type of road construction equipment, which is divided into two types: steel wheel type and tire type. Among engineering machinery, road rollers belong to the category of road equipment and are widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-viscous and viscous soils, roadbed stabilized soils, and asphalt concrete pavement layers. The road roller uses the gravity of the machine itself and is suitable for various compaction operations, causing the rolled layer to be permanently deformed and dense. When the highway is renovated and expanded, a road roller is required to compact the highway subgrade.

[0003] In view of this, the invention patent with announcement number CN211772617U discloses a static pressure roller for highway construction, including a roller body, a cab is fixedly installed on the top of the roller body, a door is movably sleeved on one side of the front of the cab, a driving seat block and a driving operation block are respectively fixedly installed on one side of the inner cavity of the cab, one side of the top of the inner cavity of the cab is movably sleeved on both ends of the first rotating shaft, and a motor is fixedly installed on one side of the bottom of the inner cavity of the cab. The static pressure roller for highway construction is made of fiberglass material on the top, both sides and the center of the rear of the cab, which improves the lighting rate of the cab. The operation of the motor can drive the first rotating shaft to rotate clockwise or counterclockwise using a belt. The first rotating shaft and the second rotating shaft are connected by a blackout cloth and two pull ropes, so that the cab can be shaded or illuminated according to different needs of the driver.

[0004] However, there are still some problems with the roller in the above patent application: during the use of the roller, impurities will adhere to the surface of the roller drum when it rotates. The roller usually needs to be equipped with a scraping mechanism to clean the impurities on the surface of the roller to ensure the operation of the roller. However, due to the high viscosity of the impurities, the impurities will adhere to the scraping mechanism, affecting the impurity removal effect of the scraping mechanism and affecting the use of the roller. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a highway reconstruction and expansion roller and a method of use to solve the problem that impurities may adhere to the surface of the roller drum when the roller is rotating, thus affecting the use of the roller.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: A highway reconstruction and expansion roller, comprising a roller body, a roller arranged on the roller body, a roller scraping mechanism being arranged on one side of the roller, and a scraper cleaning mechanism being arranged on one side of the roller scraping mechanism;

[0007] The roller scraping mechanism is rotatably connected to the roller body through a hydraulic rod assembly. The roller scraping mechanism is used to scrape impurities on the surface of the roller, and the scraper cleaning mechanism is used to clean impurities on the surface of the roller scraping mechanism.

[0010] Furthermore, two U-shaped openings are provided on one side of the movable seat, and two docking columns are provided on one side of the scraper. The docking columns are arranged in the U-shaped openings. A storage opening is provided on one side of the inner wall of each U-shaped opening. A return spring is fixed in each storage opening, and a stop block is fixed at one end of each return spring, which fixes the docking column in the U-shaped opening.

[0011] Furthermore, the stopper is fixedly connected to the return spring via a convex button, and the movable seat is connected to the scraper via bolts.

[0012] Furthermore, the scraper cleaning mechanism includes a drive box fixed on a movable seat, a drive screw is rotatably connected inside the drive box, a stepper motor is provided at one end of the drive box, the output end of the stepper motor is fixedly connected to one end of the drive screw, a square moving block is threadedly sleeved on the outer side of the drive screw, and the square moving block moves horizontally along the drive box.

[0015] Furthermore, a stepper motor switch is provided in the cab of the roller body 1 , and the stepper motor is electrically connected to the built-in battery of the roller body 1 via the stepper motor switch.

[0016] How to use the roller in highway reconstruction and expansion?

[0017] When the roller is not in use, the hydraulic cylinder on the fixed block in the roller scraping mechanism extends, acting on the connecting block, thereby causing the movable seat to rotate around the support ear, thereby moving the scraper away from the roller of the roller body to avoid wear when not in use;

[0018] When the roller is in use, the hydraulic cylinder is shortened, so that the scraper is close to the drum. When the drum rolls, the scraper can scrape off the impurities attached to its surface. At the same time, the stepper motor of the scraper cleaning mechanism drives the driving screw in the driving box to rotate, and then drives the square moving block to move back and forth horizontally. The cross-moving block can be driven by the cooperation of the support block and the T-shaped docking strip. The cleaning scraper rod can move back and forth to scrape off the impurities on the scraper surface, avoiding subsequent cleaning by personnel.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention cooperates with the scraper cleaning mechanism through the roller scraping mechanism. When the roller rolls, the roller scraping mechanism can scrape off the impurities attached to its surface. At the same time, the stepper motor of the scraper cleaning mechanism drives the driving screw, thereby making the cleaning scraper rod reciprocate along the scraper surface, thereby ensuring that the impurities on the scraper surface are cleaned, ensuring the impurity removal effect of the roller scraping mechanism, and ensuring the use effect of the roller.
