Technical Field
[0001] This utility model relates to the field of highway construction technology, specifically to a road surface leveling device for highway construction. Background Technology
[0002] After road construction, it needs to be leveled to facilitate subsequent construction. This is typically done by a vehicle-driven leveling roller, which applies pressure to the ground upon contact. For example, a road leveling device with enhanced leveling capacity is described in announcement number CN211171518U. The road leveling equipment includes a frame, wheel assembly, leveling roller, and wheel drive unit. The wheel assembly and leveling roller are spaced apart in the front-rear direction and connected to the frame. The wheel drive unit drives the wheel assembly. It also includes a scraper, positioned between the wheel assembly and the leveling roller. The scraper is V-shaped, with its tip facing the wheel assembly. The bottom surface of the scraper is parallel to and not lower than the plane formed by the bottom of the wheel assembly and the leveling roller. The scraper levels the road surface as the equipment moves forward, pushing any scraped road material to the sides. The scraper initially levels the road surface, and the leveling roller further levels it, thus improving the leveling capacity of the road sizing equipment. However, this more capable road sizing equipment still has the following drawbacks in actual use: Traditional leveling equipment typically has leveling rollers with fixed weights, making it impossible to adjust the applied pressure according to construction needs. Furthermore, during leveling, mud and sand from the road surface tend to adhere to the leveling rollers, which can negatively impact subsequent leveling. To address these issues, innovative designs are urgently needed to improve existing leveling equipment. Utility Model Content
[0003] The purpose of this utility model is to provide a road surface leveling device for highway construction, in order to solve the problems mentioned in the background art, that the weight of the leveling rollers of traditional leveling equipment is mostly fixed, and the weight of the applied pressure cannot be adjusted according to the construction needs, and that mud and sand on the road surface will adhere to the leveling rollers during leveling work, which will have a certain impact on the subsequent leveling.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a road surface leveling device for highway construction, comprising a leveling roller, wherein the leveling roller is mounted on a leveling vehicle frame, and a water injection pipe is provided on the side of the leveling roller; It also includes: a water storage cavity is provided inside the leveling roller, and a partition plate is provided inside the water storage cavity. A connecting piece is fixed at the edge of the partition plate and the connecting piece is fixedly connected to the inner wall of the water storage cavity. A cleaning mechanism is installed on the leveling roller, and the cleaning mechanism cleans the mud and sand on the surface of the leveling roller by means of gas.
[0005] Preferably, the water storage cavities are distributed at equal angles within the leveling roller, and the length and width of the partition plates are both smaller than the length and width of the water storage cavities. By setting multiple water storage cavities, different amounts of liquid can be stored.
[0006] Preferably, the connecting piece is made of rubber and is arranged around the edge of the partition plate, so that the partition plate can be moved by the connecting piece when the liquid fluctuates.
[0007] Preferably, the interior of the water storage cavity is divided by a partition plate and a connecting piece, and the smaller part of the water storage cavity is interconnected with the fixed cavity through a gas transmission channel, and the part of the water storage cavity that does not store liquid contains gas.
[0008] Preferably, the cleaning mechanism includes an air conveying channel inside the leveling roller, and the inner wall of the leveling roller has a fixed cavity, through which the gas in the water storage cavity can be transmitted to the fixed cavity via the air conveying channel.
[0009] Preferably, the fixed cavity is an annular structure, and both the fixed cavity and the gas delivery channel are distributed at equal angles, allowing the gas to be transported upwards and discharged from the gas outlet.
[0010] Preferably, the fixed cavity and the air outlet are connected, and the air outlet is evenly distributed on the surface of the leveling roller. The gas discharged from the air outlet is blown onto the surface of the leveling roller to clean it.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the road surface leveling equipment for highway construction can adjust the pressure weight according to construction needs to achieve different levelsing of the road surface, and can clean the mud and sand adhering to the leveling roller during the leveling work to ensure the smoothness of the subsequent road surface leveling. The specific details are as follows: 1. Depending on the construction requirements, different amounts of liquid are filled into the water storage chamber, resulting in different weights of the leveling roller and corresponding changes in the weight applied to the road surface; 2. When one of the water storage chambers is in the upward position, the liquid can contact the partition plate. The partition plate is subjected to force and descends through the connecting piece, squeezing the part of the water storage chamber that does not store liquid. This causes the gas inside to be transmitted to the fixed chamber through the air conveying channel and finally discharged from the air outlet, cleaning the mud and sand on the surface of the leveling roller.

[0014] 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.
[0015] Please see Figures 1-5 The present invention provides the following technical solution: Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a road surface leveling device for highway construction, comprising a leveling roller 1 mounted on a leveling frame, and a water injection pipe 2 provided on the side of the leveling roller 1; further comprising: a water storage cavity 3 opened inside the leveling roller 1, and a partition plate 4 provided inside the water storage cavity 3, with a connecting piece 5 fixed at the edge of the partition plate 4, and the connecting piece 5 fixedly connected to the inner wall of the water storage cavity 3; and a cleaning mechanism disposed on the leveling roller 1, which cleans the mud and sand on the surface of the leveling roller 1 by means of gas.
[0016] Most existing leveling equipment has leveling rollers with fixed weights, making it impossible to adjust the applied pressure according to construction needs. Figures 1-3 As shown, the water storage chambers 3 are distributed at equal angles within the leveling roller 1, and the length and width of the partition plate 4 are both smaller than the length and width of the water storage chambers 3. Liquid can be injected into the leveling roller 1 through the water injection pipe 2. Different amounts of liquid are injected according to construction needs, resulting in different weights of the leveling roller 1 and corresponding changes in the weight applied to the road surface.
[0017] Example 2: In existing leveling equipment, mud and sand from the road surface adhere to the leveling roller 1 during leveling operations, which affects subsequent leveling. Therefore, this example addresses this issue by implementing the following technical solution: Figures 3-5As shown, the connecting piece 5 is made of rubber and is arranged around the edge of the partition plate 4; the interior of the water storage cavity 3 is separated by the partition plate 4 and the connecting piece 5, and the smaller part of the water storage cavity 3 is interconnected with the fixed cavity 7 through the air supply channel 6; the cleaning mechanism includes an air supply channel 6 opened inside the leveling roller 1, and a fixed cavity 7 is opened on the inner wall of the leveling roller 1; the fixed cavity 7 has a ring structure, and the fixed cavity 7 and the air supply channel 6 are distributed at equal angles; the fixed cavity 7 is connected to the air outlet 8, and the air outlet 8 is evenly distributed on the surface of the leveling roller 1; when the leveling roller 1 rolls and flattens the road surface, it can drive the water storage... The liquid fluctuates within the water chamber 3. When one of the water storage chambers 3 is in an upward position, the liquid can contact the partition plate 4 and the connecting piece 5. The partition plate 4, under pressure, can be lowered through the connecting piece 5, squeezing the portion of the water storage chamber 3 that does not store liquid. This causes the gas inside to be transmitted through the air conveying channel 6 to the fixed chamber 7, and finally discharged from the air outlet 8, cleaning the mud and sand on the surface of the leveling roller 1. When the water storage chamber 3 is in a downward position, it does not squeeze the partition plate 4, so the gas will not be discharged. When the water storage chamber 3 is in a horizontal position, the partition plate 4 returns to its original position through the connecting piece 5, drawing in external gas for subsequent cleaning.
[0018] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
