Description

Technical Field

[0001] This utility model relates to the field of road vibration leveling technology, specifically a road subbase vibration leveler. Background Technology

[0002] During road construction, the subbase, as an important component of the pavement structure, mainly serves to bear loads, drain water, prevent freezing, and uniformly transfer loads. Its construction quality directly affects the smoothness, load-bearing capacity, and service life of the entire road. Therefore, after the subbase is laid, it must be effectively leveled and initially compacted to ensure the quality of subsequent surface layer construction. Road subbase vibratory scrapers are usually used during the leveling and compaction process.

[0003] However, current road subgrade vibratory levelers still have the following shortcomings: During operation, the road subgrade vibratory leveler easily scrapes up some subgrade material and adheres to the leveler surface. Since the vibrator is directly installed on the leveler, this causes the vibrator to come into contact with the adhered subgrade material, interfering with its normal vibration operation, thereby affecting the equipment's working efficiency and leveling effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a road subbase vibratory scraper, which facilitates raising the vibrator to reduce the contact rate between the vibrator and the subbase material.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road subbase vibratory leveler, comprising a scraper plate and a vibrator, a power supply, and a support plate mounted on the scraper plate. Two symmetrically arranged sliding rods are mounted on the upper surface of the scraper plate. The outer walls of the two sliding rods are slidably connected to the same connecting slider. The upper surface of the connecting slider is fixedly connected to the vibrator. A second mounting plate is fixedly connected to the side wall of the connecting slider. The side wall of the second mounting plate is fixedly connected to the power supply. A support plate is mounted on the second mounting plate. A limiting component is mounted on the side wall of the connecting slider.

[0006] Furthermore, the limiting member is a first limiting bolt, and the outer walls of the two sliding rods are provided with a plurality of evenly distributed first limiting threaded holes. The side wall of the connecting slider is provided with a second limiting threaded hole that is adapted to and connected to the first limiting threaded hole at the top in terms of position, shape and size. The first limiting bolt is threadedly connected to the second limiting threaded hole, and the first limiting bolt is also threadedly connected to the first limiting threaded hole.

[0007] Furthermore, the lower ends of the two slide rods are fixed to the same first mounting plate, which is in contact with the upper surface of the scraper plate. The upper surface of the first mounting plate is located on the outer side of the two slide rods and is threaded with two symmetrically arranged fastening bolts. The two fastening bolts pass through the first mounting plate into the scraper plate for bolt fastening.

[0008] Furthermore, the side wall of the support plate is provided with a plurality of evenly distributed third limiting threaded holes, and the side wall of the second mounting plate is provided with a fourth limiting threaded hole that is adapted to and connected to the third limiting threaded hole at the top in terms of position, shape and size. A second limiting bolt is threadedly connected to the fourth limiting threaded hole, and the second limiting bolt is also threadedly connected to the third limiting threaded hole.

[0009] Furthermore, a handle is fixedly attached to the upper surface of the handrail, and an anti-slip sleeve is fitted onto the outer wall of the handle.

[0010] Furthermore, a first groove is formed on the upper surface of the scraper plate on the side away from the first mounting plate, and a second groove is formed on the lower inner wall of the first groove, which is connected to the first groove. The first groove and the second groove are combined to form a T-shaped groove. A slider is slidably connected in the first groove, and an L-shaped connecting block is fixedly connected to the upper surface of the slider in the second groove. The L-shaped connecting block is a combination of a vertical rod and a horizontal rod. The vertical rod of the L-shaped connecting block is slidably connected in the second groove, and a scraper rod is fixedly connected to the lower surface of the end of the horizontal rod of the L-shaped connecting block.

[0011] Furthermore, the inner walls of both the first and second slides are smoothly formed.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through the cooperation of the sliding rod, the connecting slider and the first limiting bolt, allows the first limiting bolt to be loosened before the device is put into operation. Then, the connecting slider is slid upward, causing the vibrator and its connecting parts to move upward as a whole, maintaining a certain distance from the scraper plate. In this way, the road subbase material is less likely to come into contact with the vibrator during operation, thereby reducing the interference of the material on the normal operation of the vibrator, making its operation more stable, improving the leveling effect and construction efficiency. The structure is simple, easy to operate and highly practical. 2. This utility model, through the cooperation of the second mounting plate, the support plate, the second limiting bolt, and the handle, allows the device to be adjusted in height after the device has been raised and adjusted. To accommodate users of different heights, the second limiting bolt can be released first, and the handle can be held to adjust the height up and down. After adjusting to a suitable operating height, the second limiting bolt can be tightened to fix the position. This design enhances the adaptability of the equipment to different users and the comfort of operation. At the same time, with the scraper, the surface of the scraper plate can be easily cleaned during operation to prevent material accumulation and further improve the efficiency and quality of leveling operations.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] like Figures 1 to 5 As shown, a road subbase vibratory leveler includes a scraper plate 1 and a vibrator 2, a power supply 3, and a support plate 4 mounted on the scraper plate 1. Two symmetrically arranged slide rods 6 are mounted on the upper surface of the scraper plate 1. The outer walls of the two slide rods 6 are slidably connected to the same connecting slider 7. The upper surface of the connecting slider 7 is fixedly connected to the vibrator 2. A second mounting plate 12 is fixedly connected to the side wall of the connecting slider 7. The side wall of the second mounting plate 12 is fixedly connected to the power supply 3. The support plate 4 is mounted on the second mounting plate 12. A limiter is mounted on the side wall of the connecting slider 7.

[0017] like Figures 1 to 5 As shown, when using the road subgrade vibratory scraper of this utility model, the user can adjust the distance between the vibrator 2 and the scraper plate 1 according to the actual situation. First, take out the limiting part, then hold the connecting slider 7 and move it upward. Then, when the position is appropriate, lock the limiting part, so that the vibrator 2 is higher than the scraper plate 1. In this way, the road subgrade material scraped by the scraper plate 1 will not easily get onto the vibrator 2, affecting its working efficiency.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the limiting component is a first limiting bolt 11. Multiple evenly distributed first limiting threaded holes 9 are provided through the outer walls of the two sliding rods 6. A second limiting threaded hole 10 is provided through the side wall of the connecting slider 7, which is adapted to and connected to the first limiting threaded hole 9 located at the top in terms of position, shape and size. The first limiting bolt 11 is threadedly connected to the second limiting threaded hole 10. The first limiting bolt 11 is also threadedly connected to the first limiting threaded hole 9.

[0019] Specifically, first unscrew the first limiting bolt 11, then adjust the height of the sliding connecting slider 7. After adjusting it appropriately, align the first limiting threaded hole 9 and the second limiting threaded hole 10 at this position, and tighten the first limiting bolt 11 to fix the position.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lower ends of the two slide rods 6 are fixed to the same first mounting plate 5. The first mounting plate 5 is in contact with the upper surface of the scraper plate 1. The upper surface of the first mounting plate 5 is located on the outside of the two slide rods 6 and is threaded with two symmetrically arranged fastening bolts 8. The two fastening bolts 8 pass through the first mounting plate 5 into the scraper plate 1 for bolt fastening.

[0021] Specifically, if it is necessary to disassemble the scraper plate 1, simply remove the two fastening bolts 8 to achieve a detachable connection of the scraper plate 1, which facilitates its maintenance and repair.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the side wall of the support plate 4 is provided with a plurality of evenly distributed third limiting threaded holes 13, and the side wall of the second mounting plate 12 is provided with a fourth limiting threaded hole 14 that is adapted to and connected to the third limiting threaded hole 13 located at the top in terms of position, shape and size. The fourth limiting threaded hole 14 is internally threaded with a second limiting bolt 15, which is also internally threaded in the third limiting threaded hole 13.

[0023] Specifically, since the entire structure starting from the connecting slider 7 has been raised, to make the hand position more comfortable, first unscrew the second limiting bolt 15, then hold the handle plate 4 and slide it up and down. After the adjustment is completed, align the third limiting threaded hole 13 and the fourth limiting threaded hole 14 under this position, and tighten the second limiting bolt 15 to fix the position. This can accommodate users of different heights and different grip preferences, improving the applicability of the device.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a handle 16 is fixed to the upper surface of the handrail 4, and an anti-slip sleeve is fitted on the outer wall of the handle 16.

[0025] Specifically, by setting up the handle 16, it is easier to hold and more comfortable to work. At the same time, the anti-slip sleeve increases the frictional resistance between the human body and the handle 16, which can reduce the occurrence of hand slippage.

[0026] like Figure 4 and Figure 5 As shown, a first groove 17 is provided on the upper surface of the scraper plate 1 on the side away from the first mounting plate 5. A second groove 18 is provided on the lower inner wall of the first groove 17, which is connected to the first groove 17. The first groove 17 and the second groove 18 are combined to form a T-shaped groove. A slider 19 is slidably connected in the first groove 17. An L-shaped connecting block 20 is fixedly connected to the upper surface of the slider 19 in the second groove 18. The L-shaped connecting block 20 is a combination of a vertical rod and a horizontal rod. The vertical rod of the L-shaped connecting block 20 is slidably connected in the second groove 18. A scraper rod 21 is fixedly connected to the lower surface of the end of the horizontal rod of the L-shaped connecting block 20.

[0027] Specifically, since the scraper plate 1 scrapes up material during the working process, this material will adhere to the surface of the scraper plate 1 and affect its working efficiency. With the help of the L-shaped connecting block 20, the sliding scraper 21 moves back and forth horizontally in the first slide groove 17 and the second slide groove 18 to scrape the front side wall of the scraper plate 1, making its surface cleaner and the work better. It is worth noting that the scraper 21 is made of rubber and is in close contact with the surface of the scraper plate 1, which enhances the cleaning effect of the scraper 21.

[0028] like Figure 4 and Figure 5 As shown, the inner walls of the first groove 17 and the second groove 18 are both smoothly designed. This smooth design allows the scraper 21 to slide more smoothly and achieve a better scraping effect.

[0029] 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.
