Description

Technical Field

[0001] The utility model relates to the technical field of leveling devices, in particular to a leveling device for building earthwork construction. Background Art

[0002] A grader is an earth-moving machine that uses a scraper to level the ground. A scraper is installed between the front and rear axles of the machine, and it can be raised and lowered, tilted, rotated and extended. It is flexible and accurate in movement, easy to operate, and can level the ground with high precision. It is widely used in land leveling work.

[0003] An existing land and earth leveling device (publication number: CN220978149U) has at least the following disadvantages: the above-mentioned device rotates a threaded rod, and the threaded rod drives the telescopic plate connected to the extension block to slide on the inner wall of the receiving groove, and the telescopic plate is extended and retracted on the inner wall of the receiving groove, so that the L-shaped scraper can adapt to various land and earth needs. However, in harsh environments, the screw rod and the receiving groove are easily blocked and worn, affecting the reliability and service life of the device, and the screw rod responds slowly when the scraper width needs to be frequently adjusted, resulting in poor leveling effect of the device. For this reason, we propose the utility model. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a construction earthwork leveling device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0023] In this embodiment, a first cylinder 303 is fixed to one side of the movable shell 201, and the telescopic end of the first cylinder 303 is fixed to the top surface of the movable plate 208. The inner top surface and the top surface of the movable hole 203 are both provided with a limiting groove 301. The outer circumferential wall surface of the movable plate 204 is fixed with a limiting ring 302, and the limiting ring 302 is slidably arranged inside the limiting groove 301. Through the setting of the telescopic structure, the staff starts the first cylinder 303 to contract, so that the telescopic end of the first cylinder 303 drives the movable plate 208 to move upward. The upward movement of the movable plate 208 is pushed by the two ends of the two connecting rods 207 located at the top. The two movable disks 204 move away from each other. During the movement of the movable disk 204 in the movable hole 203, the limiting ring 302 slides in the limiting groove 301 to prevent the movable disk 204 from escaping from the movable hole 203. At the same time, when the two movable disks 204 move away from each other, they drive the two scrapers 202 to move away from each other, so that the two scrapers 202 extend from both sides of the movable shell 201. Therefore, when the device is leveling the soil, it only needs to control the extension length of the two scrapers 202 by controlling the first cylinder 303. The operation is convenient, the reliability of the device in harsh environments is improved, and the leveling effect of the device is improved.

[0024] In this embodiment, both sides of the inner wall of the movable shell 201 are provided with sliding grooves 402, and both sides of the two scrapers 202 are fixed with sliding bars 401. The sliding bars 401 and the internal sliding grooves 402 are set for sliding. When the two scrapers 202 slide in the movable shell 201, the sliding bars 401 slide synchronously in the sliding grooves 402. At the same time, the matching setting of the sliding bars 401 and the sliding grooves 402 can prevent the scrapers 202 from falling off from the movable shell 201.

[0025] In this embodiment, an angle plate 5 is fixed on one side of the two scrapers 202, and the sides of the two angle plates 5 that are close to each other are both inclined surfaces. When the movable shell 201 and the scraper 202 level the land, the soil gathered when the scraper 202 and one side of the movable shell 201 are scraped is discharged from the inclined surfaces of the two angle plates 5 to the outside of the two scrapers 202, preventing excessive soil from gathering on one side of the scraper 202 and the movable shell 201 and affecting the movement of the vehicle body 1.

[0026] In this embodiment, the top surfaces of the two corner plates 5 are fixed with filling plates 6 by bolts. Through the filling plates 6, the staff can selectively install a single filling plate 6 on the top surfaces of the two corner plates 5, so that the soil gathered between the two scrapers 202 is discharged at the corner plates 5 where the filling plates 6 are not installed, thereby discharging the soil to the unscraped area on one side of the vehicle body 1, preventing the soil from being discharged into the scraped area.

[0027] In this embodiment, a fixed plate 7 is hinged on one side of the guide block 3 close to the vehicle body 1, and a second cylinder 701 is fixed on both sides of the mounting rod 2. The telescopic end of the second cylinder 701 is hinged to the top surface of the fixed plate 7. The staff can control the telescopic end of the second cylinder 701 to drive the fixed plate 7 to rise and fall, and then drive the movable shell 201 and the scraper 202 to rise and fall, so that the scraper 202 can adapt to the leveling requirements of different terrains.

[0028] Working principle: During use, the staff starts the first cylinder 303 to contract, so that the telescopic end of the first cylinder 303 drives the movable plate 208 to move upward. The upward movement of the movable plate 208 is that the two ends of the two connecting rods 207 located at the top push the two movable plates 204 away from each other. During the movement of the movable plate 204 in the movable hole 203, the limiting ring 302 slides in the limiting groove 301 to prevent the movable plate 204 from escaping from the movable hole 203. At the same time, when the two movable plates 204 move away from each other, they drive the two scrapers 202 away from each other, so that the two scrapers 202 extend from both sides of the movable shell 201, so that when the device is leveling the soil, it only needs to control the extension length of the two scrapers 202 by controlling the first cylinder 303. When the two scrapers 202 slide in the movable shell 201, the slide bar 401 slides synchronously in the slide groove 402. At the same time, the slide bar 401 and the slide groove 402 02 can prevent the scraper 202 from falling off from the movable shell 201. When the movable shell 201 and the scraper 202 are leveling the land, the scraper 202 and one side of the movable shell 201 are scraping, and the accumulated soil is discharged from the inclined surface of the two corner plates 5 to the outside of the two scrapers 202, preventing too much soil from accumulating on one side of the scraper 202 and the movable shell 201 and affecting the movement of the vehicle body 1. The staff can selectively install a single filling plate 6 on the top surface of the two corner plates 5, so that the soil accumulated between the two scrapers 202 is discharged at the corner plate 5 where the filling plate 6 is not installed, thereby discharging the soil to the unscraped area on one side of the vehicle body 1, preventing the soil from being discharged into the leveled area. The staff can control the extension and retraction of the second cylinder 701 to drive the fixed plate 7 to rise and fall, and then drive the movable shell 201 and the scraper 202 to rise and fall, so that the scraper 202 can adapt to the leveling requirements of different terrains.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
