Technical Field
[0001] This utility model relates to the technical field of compaction and leveling devices, specifically a compaction and leveling device for steel slag cement stabilized crushed stone. Background Technology
[0002] Steel slag cement-stabilized crushed stone is a new type of road base material formed by mixing steel slag as aggregate, cement as binder, and appropriate amounts of aggregates and water. Steel slag, an important product of industrial solid waste recycling, possesses excellent properties such as high strength and high wear resistance. The stabilized crushed stone structure formed by mixing it with cement and aggregates has both high load-bearing capacity and durability, effectively improving the strength, rigidity, and deformation resistance of the road base. It is widely used in the construction of highways, municipal roads, and industrial park roads. Compacting and leveling steel slag cement-stabilized crushed stone is a key process in road construction. Compaction ensures that the crushed stone particles are tightly packed, eliminating gaps between particles, improving the density and integrity of the base layer, and preventing road surface cracking and deformation caused by loosening and settlement during later use. At the same time, a level base layer provides a smooth working surface for subsequent surface layer construction, ensuring the overall construction quality and performance of the road surface.
[0003] Based on the above, the inventors have discovered the following problems: Due to the extremely high hardness of steel slag itself, and the irregular shape of the crushed stone particles formed after crushing, traditional compaction devices mostly rely on their own weight for compaction. Their force is insufficient to effectively crush the large hard particles in the steel slag crushed stone, nor can it completely disperse the "suspended" accumulation structure formed by irregular particles. This leads to two major problems when traditional devices are in operation: First, the compaction is uneven, and the protruding parts of the irregular particles are difficult to be completely flattened, resulting in local height differences in some areas due to particle obstruction; Second, the local compaction is insufficient, and the gaps between particles cannot be fully filled by conventional compaction.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a steel slag cement stabilized crushed stone compaction and leveling device in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide a steel slag cement stabilized crushed stone compaction and leveling device to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A steel slag cement stabilized crushed stone compaction and leveling device includes a connecting assembly, a first leveling assembly, and a second leveling assembly. The first leveling assembly includes a first support, an impact wheel body is disposed inside the first support, and a fixing frame is disposed inside the impact wheel body. The fixing frame has sliding grooves on both sides of its inner wall near the bottom end, and an impact block is slidably connected between a pair of sliding grooves. The fixing frame has a pair of moving grooves, and a connecting rod is slidably disposed inside each pair of moving grooves. The bottom surfaces of the two connecting rods are fixedly connected to the top surfaces of the impact blocks. A dual-axis motor is installed at the center of the inner bottom surface of the fixing frame. An eccentric block is welded to each of the two output ends of the dual-axis motor. The two connecting rods are hinged to the two eccentric blocks at the ends away from the impact blocks. The second leveling assembly includes a second support, a connecting arm, a disc spring, a plate, and a vibration motor.
[0007] The beneficial effects of adopting the above-mentioned further solution are as follows: the dual-axis motor of the first leveling component drives the eccentric block to rotate, causing the connecting rod to slide up and down in the square groove. At the same time, the connecting rod drives the impact block to slide up and down along the slide groove, so that the impact block continuously impacts the inner wall of the impact wheel. During the rolling process, the impact wheel generates a high-frequency impact force, which can effectively crush large hard particles in the crushed stone and disperse the irregular particle accumulation structure, avoiding insufficient compaction caused by local voids. The vibration motor of the second leveling component drives the plate to generate high-frequency vibration. Combined with the pre-compaction effect of the impact wheel, it performs secondary leveling and compaction on the crushed stone layer after impact. The vibration force can rearrange the crushed stone particles and fill the gaps between the particles, further improving the overall compaction and surface smoothness. Through the initial impact and secondary vibration, the problems of uneven rolling and insufficient local compaction that are prone to occur in traditional rolling devices are solved.
[0008] Furthermore, the outer walls of the impact wheel are rotatably connected to the inner walls of the first bracket on both sides. A through hole is provided at the center of each outer wall of the impact wheel. The two ends of the fixing frame extend to the outside of the impact wheel through the through holes, and the two ends of the fixing frame are fixedly connected to the inner walls of the first bracket on both sides. A shock-absorbing rubber ring is fitted on the outer walls of both ends of the fixing frame, and the outer walls of the two shock-absorbing rubber rings are rotatably engaged with the inner walls of the two through holes.
[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: the rotatable connection between the impact wheel and the first support ensures that the impact wheel can roll adaptively on the working surface during the compaction process, ensuring the comprehensiveness of the compaction coverage; the fixed frame is fixed to the first support, providing a stable installation foundation for core components such as the dual-axis motor and the impact block; the setting of the shock-absorbing rubber ring reduces friction and wear between the fixed frame and the through hole of the impact wheel, extending its service life, and absorbs the vibration energy generated by the impact operation, reducing the transmission of vibration to the first support and the whole machine, avoiding loosening of the device connection due to high-frequency impact, ensuring the stability of the operation process, and reducing the vibration impact on traction equipment (such as excavators).
[0010] Furthermore, the bottom surface of the impact block is arc-shaped, and the bottom surface of the impact block matches the inner wall of the impact wheel.
[0011] The beneficial effect of adopting the above-mentioned further solution is that the fit between the bottom surface of the impact block and the inner wall of the impact wheel allows the impact block to fully fit with the inner wall of the wheel when sliding up and down, so as to evenly transmit the impact force to the impact wheel and ensure that the impact energy is efficiently converted into the crushing impact force of the impact wheel on the crushed stone layer, allowing the high-frequency impact to act more accurately on the hard particles of steel slag cement stabilized crushed stone.
[0012] Furthermore, the inner top surface of the first bracket is arc-shaped, and the inner top surface of the first bracket matches the outer wall of the impact wheel.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the arc-shaped fit between the inner top surface of the first support and the outer wall of the impact wheel forms a limiting support for the impact wheel, preventing the wheel from shifting left or right or jumping during rolling or impact operations, ensuring the straightness and stability of the compaction trajectory. At the same time, when the impact wheel rolls and compacts with the working surface, the side wall of the first support scrapes and cleans the adhesive on the outer wall of the impact wheel.
[0014] Furthermore, the two output ends of the dual-axis motor have the same speed and direction of rotation.
[0015] The beneficial effects of adopting the above-mentioned further solution are that the speed and direction of the two output ends of the dual-shaft motor are completely synchronized, which can drive the two eccentric blocks to rotate synchronously. Through the connecting rod, the impact block is driven to slide smoothly up and down along the slide groove, avoiding the tilting or jamming of the impact block due to inconsistent driving forces at both ends, or the uneven load on the impact wheel body. The symmetrical and stable impact force can allow the impact wheel body to apply uniform crushing impact to the crushed stone layer, ensuring that the crushing and compaction degree of each area of the working surface is consistent, avoiding insufficient compaction due to insufficient impact in some areas, or loose crushed stone layer due to excessive impact, effectively solving the problem of uneven compaction of steel slag cement stabilized crushed stone.
[0016] Furthermore, there are two connecting arms and two butterfly springs. The two connecting arms are respectively installed on both sides of the inner wall of the second bracket, and the two butterfly springs are respectively installed at the bottom of the two connecting arms. The plate is set below the pair of butterfly springs. The two butterfly springs are fixedly connected to the top surface of the plate at the end away from the connecting arms. The vibration motor is installed at the center of the top surface of the plate.
[0017] The beneficial effects of adopting the above-mentioned further scheme are that the two connecting arms and the butterfly spring are symmetrically arranged to provide balanced elastic support for the plate, so that the plate can always remain horizontal during vibration and avoid local compaction omissions caused by uneven force; the butterfly spring has good elastic buffering performance, which allows the plate to adapt to the slight undulations of the working surface and ensures that the plate and the crushed stone layer are in close contact; the vibration motor is installed in the center of the plate and can evenly transmit vibration energy to the entire plate, driving the surrounding steel slag cement stabilized crushed stone to vibrate together. During the vibration, the originally stationary small particles will gain kinetic energy and begin to move in the gaps formed by the large particles. Since the friction between particles is reduced under the action of vibration, the small particles are more likely to fill the gaps of the large particles, thereby achieving the purpose of improving the overall density.
[0018] Furthermore, the connecting assembly includes a reinforcing strip, the bottom sides of which are fixedly connected to the top surfaces of the first bracket and the second bracket, respectively. The reinforcing strip has a groove inside, and a connecting seat is installed inside the groove. The connecting seat is connected to the boom of the excavator by bolts.
[0019] The beneficial effects of adopting the above-mentioned further solutions are that the reinforcing strip firmly connects the first support and the second support into one unit, improving the overall structural strength of the device; the connecting seat is connected to the excavator boom by bolts, which is firm and easy to disassemble, and can quickly realize the assembly and separation of the device and the traction equipment; the flexible operation of the excavator, combined with the compaction function of the device, allows for focused operation on areas with insufficient compaction of steel slag cement stabilized crushed stone, thereby improving the overall construction quality.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: In the first leveling component of this steel slag cement stabilized crushed stone compaction and leveling device, a dual-shaft motor drives an eccentric block to rotate, which in turn drives an impact block to slide up and down along a groove at high frequency via a connecting rod, continuously impacting the inner wall of the impact wheel. This causes the impact wheel to generate a dual force of self-weight compaction and instantaneous impact when rolling, effectively crushing large hard particles in the steel slag or pressing irregular protruding particles into the base layer, while simultaneously breaking up the particle-supported structure. In the second leveling component, a vibrating motor drives a flat plate to generate high-frequency vibration, which, in conjunction with a butterfly spring, creates a high-frequency vibration. The elastic contact of the spring causes the surrounding steel slag cement-stabilized crushed stone to vibrate. During the vibration, the originally stationary small particles gain kinetic energy and begin to move in the gaps formed by the large particles. As the friction between the particles decreases under the action of vibration, the small particles can more easily fill the gaps between the large particles, thereby achieving the purpose of improving the overall density. Through the orderly cooperation of the two-stage components, the crushing and pressing of large particles is achieved efficiently, fully adapting to the characteristics of high hardness and irregular particle size of steel slag, and solving the problems of uneven rolling and insufficient local compaction of traditional devices.

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.
[0024] Please see Figures 1-5This utility model provides a technical solution: a steel slag cement stabilized crushed stone compaction and leveling device, including a connecting component 1, a first leveling component 2, and a second leveling component 3. The first leveling component 2 includes a first support 21, an impact wheel 22 is provided inside the first support 21, and a fixing frame 23 is provided inside the impact wheel 22. The fixing frame 23 has sliding grooves on both sides of its inner wall near the bottom end, and an impact block 24 is slidably connected between a pair of sliding grooves. A pair of moving grooves are provided on the fixing frame 23, and a connecting rod 25 is slidably provided inside each pair of moving grooves. The bottom surfaces of the two connecting rods 25 are fixedly connected to the top surface of the impact block 24. A dual-axis motor 26 is installed at the center of the inner bottom surface of the fixing frame 23. Eccentric blocks 27 are welded to both output ends of the dual-axis motor 26. Two connecting rods 25 are hinged to the two eccentric blocks 27 at their ends away from the impact block 24. The second leveling component 3 includes a second bracket 31, a connecting arm 32, a disc spring 33, a plate 34, and a vibration motor 35. The outer walls of the impact wheel 22 are rotatably connected to the inner walls of the first bracket 21 on both sides. Through holes are provided at the center of both sides of the outer walls of the impact wheel 22. Both ends of the fixing frame 23 extend to the outside of the impact wheel 22 through these through holes, and both ends of the fixing frame 23 are respectively connected to the second bracket 24. The inner walls of the bracket 21 are fixedly connected on both sides. The outer walls of both ends of the fixing frame 23 are fitted with shock-absorbing rubber rings. The outer walls of the two shock-absorbing rubber rings rotatably engage with the inner walls of the two through holes. The bottom surface of the impact block 24 is arc-shaped and matches the inner wall of the impact wheel 22. The inner top surface of the first bracket 21 is arc-shaped and matches the outer wall of the impact wheel 22. The speed and direction of the two output ends of the dual-axis motor 26 are consistent. The dual-axis motor 26 drives the eccentric block 27 to rotate, and the connecting rod 25 drives the impact block 24 to slide up and down along the groove, continuously impacting the inner wall of the impact wheel 22. The wall allows the impact wheel 22 to generate high-frequency impact force during rolling. Combined with the arc-shaped fit design between the impact block 24 and the impact wheel 22, the impact energy can be evenly transferred to the crushed stone layer, effectively crushing large hard particles in the steel slag or pressing irregular protruding particles into the base layer. The rotating connection between the impact wheel 22 and the first support 21 ensures comprehensive compaction coverage. The shock-absorbing rubber ring reduces component wear and vibration transmission. The arc-shaped fitting structure on the inner top surface of the first support 21 not only prevents the impact wheel 22 from shifting but also scrapes off the adhesive on the wheel surface. The synchronous drive design of the dual-axis motor 26 ensures uniform impact force and avoids uneven local compaction.
[0025] 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.
[0026] Please see Figures 1-5 This utility model provides a technical solution: There are two connecting arms 32 and two butterfly springs 33. The two connecting arms 32 are respectively installed on both sides of the inner wall of the second bracket 31, and the two butterfly springs 33 are respectively installed at the bottom ends of the two connecting arms 32. A plate 34 is disposed below the pair of butterfly springs 33. The ends of the two butterfly springs 33 away from the connecting arms 32 are fixedly connected to the top surface of the plate 34. A vibration motor 35 is installed at the center of the top surface of the plate 34. The connecting assembly 1 includes a reinforcing strip 11. The bottom sides of the reinforcing strip 11 are fixedly connected to the top surfaces of the first bracket 21 and the second bracket 31, respectively. A groove 12 is provided inside the reinforcing strip 11, and the groove 12 contains... Equipped with a connecting seat 13, which is connected to the excavator's outrigger via bolts; the vibrating motor 35 drives the plate 34 to vibrate at high frequency, and with the elastic adaptation of the disc spring 33, it drives the surrounding steel slag cement stabilized crushed stone to vibrate together. During the vibration process, the originally stationary small particles will gain kinetic energy and begin to move in the gaps formed by the large particles. As the friction between the particles decreases under the action of vibration, the small particles are more likely to fill the gaps of the large particles, thereby achieving the purpose of improving the overall density; the device is fixedly connected to the excavator's outrigger via the connecting seat 13 of the connecting component 1 and bolts, and the reinforcing strip 11 firmly connects the first bracket 21 and the second bracket 31 into one unit to ensure the overall structural strength.
[0027] Specifically, the working principle of this steel slag cement stabilized crushed stone compaction and leveling device is as follows: During use, the device is first fixedly connected to the excavator boom via the connecting seat 13 and bolts of the connecting component 1. The reinforcing strip 11 securely connects the first support 21 and the second support 31 into a single unit, ensuring the overall structural strength. The condition of each component is checked to ensure that the impact wheel 22 rotates flexibly, the shock-absorbing rubber ring fits well, the impact block 24 is compatible with the inner wall of the impact wheel 22, and the flat plate 34 naturally conforms to the plane under the action of the disc spring 33. The excavator is started to adjust the device height so that both the impact wheel 22 and the flat plate 34 contact the surface of the steel slag cement stabilized crushed stone layer. Then, the dual-shaft motor 26 and the vibration motor 35 are started, and the two output ends of the dual-shaft motor 26 rotate synchronously. The eccentric block 27 drives the connecting rod 25 and the impact block 24 to slide up and down the groove at high frequency. The impact block 24 continuously impacts the inner wall of the impact wheel 22, so that the impact wheel 22 generates a dual force of self-weight crushing and high-frequency impact when rolling, which effectively crushes large hard particles in the steel slag or presses irregular protruding particles into the base layer. The vibration motor 35 drives the plate 34 to vibrate at high frequency. With the elastic adaptation of the butterfly spring 33, it drives the surrounding steel slag cement stabilized crushed stone to vibrate together. During the vibration process, the originally stationary small particles will gain kinetic energy and begin to move in the gaps formed by the large particles. Since the friction between the particles is reduced under the action of vibration, the small particles are more likely to fill the gaps of the large particles, thereby achieving the purpose of improving the overall density. The excavator is operated to drive the device to move at a constant speed along the preset path. The first leveling component 2 first completes the initial impact compaction, and the second leveling component 3 then performs secondary vibration compaction. The inner top surface of the first support 21 scrapes off the adhesive material adhering to the impact wheel 22 in real time, and the shock-absorbing rubber ring reduces the impact of vibration on the excavator. Finally, the uniform compaction and leveling of the crushed stone layer are achieved, solving the problem of uneven compaction and insufficient local compaction caused by the high hardness and irregular particle size of the crushed stone in traditional devices.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
