Description

Technical Field

[0001] This invention mainly relates to the field of road surface crushing equipment, specifically a cement road surface crusher that combines crushing and compaction. Background Technology

[0002] Against the backdrop of continuous improvement in the road traffic infrastructure maintenance system and the ongoing upgrading of construction mechanization, traditional manual and small-scale machinery maintenance methods are no longer adequate to meet the demands of modern road construction efficiency and standardized operations. With the widespread adoption of large-scale road construction machinery, milling machines, with their core advantages of high cutting precision, wide operating coverage, and strong construction adaptability, are gradually replacing traditional construction equipment and becoming the core main equipment in highway and urban road pavement repair and old pavement renovation projects. They are widely used in various maintenance construction scenarios such as milling and removal, defect treatment, and layer modification of asphalt and cement concrete pavements.

[0003] In the current stage of engineering construction, the core construction process of conventional road milling operations relies entirely on the key working component of the milling machine—the milling drum. The high-speed rotation of the milling drum drives the cutting tools to continuously cut, break, and peel off old road structures such as asphalt and cement concrete, thereby completing the overall demolition and cleaning of the old road surface layer and laying the foundation for subsequent road renovation construction.

[0004] Currently, the mainstream traditional road milling construction process in the industry is a segmented operation mode. After the milling machine completes the on-site road crushing operation, the resulting waste road mixture cannot be directly used for on-site reuse. On-site, the crushed loose road material must first be collected and transported to the site using supporting equipment such as loaders and transport vehicles. It is then transported to a professional mixing plant for secondary centralized crushing, screening and purification, proportioning and adjustment, and other processing steps. Impurities in the mixture are removed, and the aggregate particle size is optimized to meet the standards for road paving materials. Only then is it transported back to the construction site for subsequent paving and compaction operations.

[0005] This traditional construction process is complex and lengthy, with significant shortcomings. In terms of time efficiency, material transfer, off-site secondary processing, and round-trip transportation consume a large portion of the construction period, resulting in long intervals between processes and a substantial increase in the overall construction cycle. This is particularly problematic in time-constrained scenarios such as urban roads and main thoroughfares, easily leading to traffic congestion and prolonged road occupancy. From a cost perspective, the entire process involves multiple expenses, including machinery rental, material transportation, on-site processing, and labor allocation. The large investment in equipment and manpower, coupled with high material loss rates, significantly increases the overall cost of road renovation projects, resulting in low economic returns. Furthermore, the overlapping operations of multiple processes and equipment also increase the difficulty of on-site construction management and raise safety risks.

[0006] Due to the numerous drawbacks of traditional processes, the integrated on-site crushing and paving construction model has become an important direction for optimizing road construction processes. If the inherent procedures of off-site processing can be eliminated, and the crushed mixture can be directly processed and paved on-site after the road milling and crushing operations are completed, redundant processes such as material transfer, off-site secondary crushing and screening, and secondary transportation can be eliminated. This fundamentally simplifies the construction process and shortens the construction cycle. This optimization approach can effectively reduce investment in construction equipment and labor costs, reduce material transportation losses and on-site processing costs, comprehensively improve the operational efficiency and economic benefits of road resurfacing construction, while shortening the time road occupancy during construction and reducing the negative impact of construction on surrounding traffic and the environment. It possesses extremely high engineering application value and promotional significance. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a cement pavement crusher that combines crushing and compaction. It organically integrates a milling machine and a road roller, achieving the effect of secondary crushing after crushing and screening of the pavement. This allows the pavement material to better meet the particle size requirements for paving, enabling the on-site paving of damaged pavements without the need for transportation, thus shortening the construction cycle and reducing construction costs.

[0008] To achieve the above objectives, the present invention employs the following technical solution: A cement road surface crusher that combines crushing and compaction includes a vehicle body. The vehicle body adopts a tracked chassis or a wide-tire chassis to adapt to the driving and operation needs under different working conditions. The vehicle body is driven by gasoline, diesel or new energy power to provide continuous and stable operating power for the whole machine. A milling unit is installed at the front end of the vehicle body, and a vibration crushing unit is installed at the rear end of the vehicle body. The milling unit includes a milling frame, which is hinged to the front end of the vehicle body. A front-mounted clamping cylinder is hinged between the top of the front end of the vehicle body and the top of the milling frame. A milling drum is rotatably installed at the bottom of the milling frame, and the height of the milling drum is adjustable. The front end of the vehicle body has a front output shaft, which is connected to the milling drum via a transmission mechanism. A baffle is installed at the front end of the milling frame, and a filter plate is installed at the rear end of the milling frame. The filter plate is inclined towards the milling drum, and a plurality of filter holes are arrayed on the filter plate. A plurality of milling teeth are provided on the milling drum. The vibration crushing unit includes a vibration frame, which is hinged to the rear end of the vehicle body. A rear-mounted clamping cylinder is hinged between the top of the rear end of the vehicle body and the top of the vibration frame. A vibration drum is rotatably installed on the vibration frame, and a hydraulically driven flywheel assembly is rotatably installed inside the vibration drum. A plurality of vibration teeth are provided on the vibration drum. This device performs secondary fine crushing and preliminary compaction of the milled mixture through the coordinated operation of pre-milling and post-vibration crushing.

[0009] Preferably, the milling frame has symmetrical grooves on both sides, within which shaft seats are slidably mounted. The milling drum is rotatably mounted between two shaft seats, which are connected by a connecting frame. Several lifting cylinders are installed between the milling frame and the connecting frame. This structure allows for precise adjustment of the milling drum's height from the ground and the working depth, ensuring consistent flatness and depth during milling operations and effectively avoiding material waste and damage to the substrate caused by excessively deep or shallow milling.

[0010] Preferably, the milling teeth on the milling drum are a mixture of cutting teeth and conical breaking teeth.

[0011] Preferably, the milling drum has a central main milling cutter area and two side milling cutter areas. The main milling cutter area has several main milling cutter seats spirally arranged from the center outwards, with the spiral directions of the side main milling cutter seats opposite. The side milling cutter areas have several side milling cutter seats arranged in a ring. The main milling cutter seats are provided with conical crushing teeth and cutting teeth, and the side milling cutter seats are provided with conical crushing teeth. This combination of dual crushing cutters not only enhances cutting efficiency but also optimizes the particle size distribution of the crushed material.

[0012] Preferably, a plurality of mixing cutter seats are provided at the center of the main milling cutter area, and mixing heads are provided on the mixing cutter seats. The mixing heads can forcibly stir and homogenize the materials gathered in the middle, break the original gradation structure, promote the uniform fusion of new and old materials, and provide an ideal gradation basis for subsequent compaction operations.

[0013] Preferably, the vibrating teeth are conical breaking teeth.

[0014] Preferably, a protective housing is provided above the vibrating drum.

[0015] Preferably, multiple vibrating drums are provided, and the multiple vibrating drums are arranged linearly and evenly. The vibrating frame is provided with mounting arms that correspond one-to-one with the vibrating drums.

[0016] Preferably, the vibrating drum is rotatably mounted between the mounting arms, the mounting arms are hinged to the vibrating frame, and a hydraulic adjustment mechanism is provided between the mounting arms and the vibrating frame.

[0017] Preferably, the vibrating drums are arranged in two rows, with the two rows of vibrating drums staggered, and a hydraulic adjustment mechanism is provided between the two rows of vibrating drums and the vibrating frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This invention integrates a milling structure and a vibratory crushing structure, achieving integrated continuous operation of "milling-crushing-screening-secondary crushing-initial compaction". Through the synergistic cooperation of pre-milling and post-vibratory crushing, the recycling rate and construction efficiency of old road materials are significantly improved. Simultaneously, the unique spiral reverse milling cutter layout and central mixing design effectively solve the problems of material accumulation and segregation, ensuring the uniformity of the recycled mixture. The introduction of a hydraulic adjustment mechanism allows each working unit to adaptively adjust in real time according to road surface undulations, greatly reducing equipment impact and wear caused by uneven road surfaces and extending the service life of key components.

[0019] This integrated design significantly reduces the connection time and site occupation required for alternating operations of multiple machine types in traditional construction, thereby significantly reducing construction costs. In addition, its highly integrated modular structure simplifies on-site maintenance procedures and improves equipment maintainability and uptime. Attached Figure Description

[0022] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0023] like Figure 1-7 As shown, the cement pavement crusher of the present invention, which combines crushing and compaction, includes a vehicle body 3, a milling unit 1 at the front end of the vehicle body 3, and a vibrating crushing unit 2 at the rear. The milling unit 1 is used to crush the pavement and screen the crushed stone to ensure that the stone reaches a certain particle size requirement before being released. The vibrating crushing unit 2 is used to further compact and crush the pavement stone, making the stone particle size more uniform, thereby improving the density and smoothness of the pavement base layer. During operation, the vehicle body 3 moves forward, and the milling unit 1 contacts the pavement first. The milling drum 13 rotates at high speed, driving the milling teeth 4 to cut and crush the cement pavement. The crushed material is screened by the filter plate 15. Stone that meets the particle size requirement falls to the lower layer, while oversized particles are intercepted and re-enter the crushing cycle to ensure uniform output particle size. Subsequently, the material enters the processing area of ​​the vibrating crushing unit 2. The vibratory crushing unit 2 further compacts and cuts the crushed stone. Through the high-frequency vibration of the vibrating drum 23 and the impact of the conical crushing teeth 44, the aggregate particle size is effectively refined and internal voids are eliminated.

[0024] Specifically, the milling unit 1 includes a milling frame 11, which serves as the supporting skeleton for the milling elements and is detachably connected to the vehicle body 3. Specifically, the milling frame 11 is hinged to the front side of the vehicle body 3, and a front-mounted clamping cylinder 12 is hinged between the top of the front side of the vehicle body 3 and the top of the milling frame 11. The front-mounted clamping cylinder 12 is used to adjust the pitch angle and downward pressure of the milling frame 11, thereby adapting to road conditions of different hardness. Furthermore, when driving on normal roads, the milling frame 11 can be raised to a high position and locked to prevent non-operational collisions between the milling teeth 4 and the ground, ensuring driving safety and reducing component wear.

[0025] A milling drum 13 is rotatably mounted at the bottom of the milling frame 11. The front end of the vehicle body 3 has a front output shaft, which is connected to the milling drum 13 via a transmission mechanism. Specifically, to match the swinging motion of the milling frame 11, a drive shaft parallel to the axis of the milling drum 13 is rotatably mounted on the rear side of the milling frame 11. Power is transmitted between the drive shaft and the drive shaft of the milling drum 13 via a transmission chain or belt. A central output shaft is connected to the front output shaft via several couplings. The central output shaft is perpendicular to the drive shaft and is connected to the drive shaft via a bevel gear reducer. The transmission mechanism is externally protected to prevent damage or safety hazards caused by flying debris.

[0026] The milling drum 13 is equipped with several milling teeth 4. Specifically, the milling teeth 4 on the milling drum 13 are a mixture of cutting teeth and conical crushing teeth. The conical crushing teeth are used for initial cutting and stripping of the road surface, while the cutting teeth are responsible for subsequent fine cutting and material stripping. The two work together to effectively cope with the impact resistance of high-hardness cement road surfaces and ensure a balance between crushing efficiency and tool life. In addition, the milling teeth 4 are made of wear-resistant alloy material and are fixed in the cutter holder of the milling drum 13 through a quick-release structure. Specifically, the milling drum 13 has a central main milling cutter area and two side milling cutter areas. Several main milling cutter holders 41 are spirally arranged from the center to both ends of the main milling cutter area. The main milling cutter holders 41 on both sides spiral in opposite directions. When the milling drum 13 rotates, the milling cutter holders 41 are used to gather the milled stone towards the center. Conical crushing teeth 44 and cutting teeth 45 are installed on the main milling cutter holders 41 in a front-to-back position to form a continuous cutting trajectory. The front conical crushing teeth 44 first cut into the road surface, using their sharp geometry to pierce the surface layer, creating micro-cracks and stripping away large pieces of material. Following closely behind, the cutting teeth 45 perform secondary cutting and smoothing of the loosened material, ensuring the smoothness of the milled surface and refining the aggregate particle size. The main milling cutter holders 41 are arranged in a spiral pattern to optimize material flow, allowing the crushed aggregate to smoothly converge towards the center into the high-efficiency cutting zone of the main milling cutter, improving crushing efficiency. The side milling cutter area has several side milling cutter holders 42 arranged in a ring, with at least one row of side milling cutter holders 42. Conical crushing teeth 44 are installed on the side milling cutter holders 42. The side milling cutter area is responsible for handling the edges and uneven areas of the road surface. Its tool layout balances cutting depth and coverage width, ensuring the milled smoothness of the shoulder and corner areas.

[0027] A baffle 14 is installed on the front side of the milling frame 11. The baffle 14 is used to block the flying gravel and dust during the milling process, and at the same time guides the milled material to fall into the milling area for further crushing. The baffle 14 is made of high-strength wear-resistant steel plate, and its lower edge conforms to the road surface contour to minimize dust overflow. The inner side of the baffle 14 is also provided with guide ribs to further constrain the material trajectory and prevent large pieces of aggregate from rebounding and impacting the main body of the equipment. A filter plate 15 is installed on the rear side of the milling frame 11. The filter plate 15 is inclined towards the milling drum 13, and several filter holes are arrayed on the filter plate 15. As the vehicle body 3 moves forward, the centrifugal force generated by the high-speed rotation of the milling drum 13 throws the crushed material backward. After the material hits the filter plate 15, larger particles are intercepted and fall back below the milling drum for secondary crushing, while fine materials that meet the particle size requirements fall through the mesh of the filter plate 15 and are thus laid on the road surface.

[0028] The height of the milling drum 13 is adjustable, achieving stepless adjustment via a hydraulically driven lifting cylinder 18 to adapt to milling operations at different depths. Specifically, the extension and retraction of the hydraulic cylinder piston rod directly drives the milling drum 13 to smoothly rise and fall along the guide rail, ensuring the accuracy and stability of milling depth control. Specifically, the milling frame 1 has symmetrical sliding grooves 16 on both sides, with wear-resistant sliders embedded within the grooves 16. Shaft seats 17 are slidably mounted within the grooves 16, and the milling drum spindle is rotatably mounted within the shaft seats 17. The top of the hydraulic cylinder piston rod is connected to the shaft seats 17. When the hydraulic system drives the piston rod to extend and retract, the two shaft seats 17 slide synchronously along the grooves 16, driving the milling drum spindle to rise and fall synchronously. More specifically, to adapt to the transmission mechanism of the milling drum 13, the grooves 16 are angled, thus maintaining a constant relative position between the milling drum spindle and the drive shaft during lifting and lowering, ensuring that the transmission chain or belt is always in optimal meshing condition.

[0029] Furthermore, several mixing cutter seats 33 are set at the center of the main milling cutter area, and multiple mixing heads 46 are set on the mixing cutter seats 43. The mixing heads 46 are set in the gaps of the main milling cutter seats 41. They are square in structure, with sharp edges and corners and covered with a hard alloy layer. They are used to mix and level the road base material after preliminary milling and screening.

[0030] The vibratory crushing unit 2 includes a vibratory frame 21, which is hinged to the rear side of the vehicle body 3. A vibratory drum 23 is rotatably mounted on the vibratory frame 21. A rear-mounted clamping cylinder 22 is hinged between the top of the rear side of the vehicle body 3 and the top of the vibratory frame 21. The rear-mounted clamping cylinder 22 is used to adjust the tilt angle and downward pressure of the vibratory frame 21, thereby ensuring that the vibratory crushing unit 2 is in close contact with the road surface. The vibratory drum 23 integrates a hydraulically driven high-frequency vibrator, which generates a vertically downward periodic impact force through the rotation of the flywheel assembly inside. Several vibratory teeth 5 are evenly arranged on the vibratory drum 23. The vibratory teeth 5 are conical crushing teeth 44, whose tips are embedded in stones, and generate micro-amplitude reciprocating motion under the action of high-frequency excitation force. This micro-amplitude high-frequency impact not only effectively crushes the hardened blocks remaining on the road surface, but also further compacts the loose aggregate and eliminates interlayer voids. The conical design of the vibratory teeth 5 facilitates deep cutting into the material layer, while reducing travel resistance and avoiding material accumulation. Under the combined action of excitation force and downward pressure, the vibrating drum 23 can achieve deep reconstruction and densification of the road base layer.

[0031] More specifically, the vibrating tooth 5 has a vibrating cutter holder, which, like the main milling cutter holder 41 and the side milling cutter holder 42, is bolted to the circumferential surface of the vibrating drum 23 / milling drum 13. This modular installation structure not only facilitates the quick replacement of severely worn vibrating teeth 5, but also allows for flexible adjustment of the tooth profile and density according to actual working conditions. Anti-loosening washers and locating pins are provided at the bolt connections to resist the risk of loosening caused by high-frequency vibration and ensure structural stability during operation.

[0032] A protective shell 25 is installed above the vibrating drum 23. The protective shell 25 is welded from high-strength wear-resistant steel plate, which effectively suppresses the splashing of gravel. Example:

[0033] Compared to Embodiment 1, the structure of the vibrating drum 23 differs in this embodiment. Specifically, multiple vibrating drums 23 are provided in this embodiment, arranged linearly and uniformly. A mounting arm 27, corresponding to each vibrating drum 23, is provided on the vibrating frame 21. A preset distance is maintained between the vibrating drums 23 in the same row to cover a wider working width. The vibrating drums 23 are rotatably mounted between the mounting arms 27, which are hinged to the vibrating frame 21. Each mounting arm 27 is independently hinged to the vibrating frame 21 and is equipped with an independent hydraulic adjustment mechanism 26, thereby adapting to local undulations and hardness differences in the road surface, ensuring that each vibrating drum 23 can independently conform to the road surface conditions and achieve dynamic compaction. In this embodiment, the hydraulic adjustment mechanism 26 is a hydraulic shock absorption mechanism, which can press the vibrating drum 23 together using pressure and spring preload, while dynamically absorbing the impact load transmitted from the road surface. This independent follow-up mechanism effectively avoids the overall lifting of the equipment due to local road surface protrusions, thereby ensuring that the vibrating drum 23 in other areas can still maintain effective downward pressure, thus improving the uniformity of the overall operation and the compaction quality.

[0034] In another embodiment, two rows of vibrating drums 23 are arranged alternately. A hydraulic adjustment mechanism 26 is provided between the two rows of vibrating drums 23 and the vibrating frame 21. A slide groove is provided on the vibrating frame 21, and a shaft seat is vertically slidably installed in the slide groove. The shaft seat is connected to the hydraulic adjustment mechanism 26 to realize the floating adjustment of the vibrating drum 23 in the vertical direction. A guide bushing is provided between the shaft seat and the inner wall of the slide groove to reduce frictional resistance and improve sliding accuracy. The staggered layout allows the working trajectories of the front and rear rows of vibrating teeth 5 to complement each other, which can overcome the leakage pressure or crushing blind spots that may occur with single-row vibration. In addition, the shearing effect generated by the staggered arrangement helps to create an air gap between crushed aggregates, further promoting the rearrangement and interlocking of aggregates, thereby significantly improving the overall density and load-bearing capacity of the road surface.
