Description

Technical Field

[0001] The invention relates to a road surface crushing and recycling device, belonging to the technical field of road surface demolition. Background Art

[0002] Asphalt pavements are widely used in transportation infrastructure such as urban roads, highways, and parking lots due to their excellent compressive strength, durability, and comfortable driving performance. However, with increasing traffic volume and the impact of environmental factors, asphalt pavements inevitably develop defects such as cracks, spalling, and deformation during use, leading to a decline in pavement performance and affecting driving safety and comfort. Therefore, regular asphalt pavement dismantling and maintenance are necessary. Dismantling involves stripping the asphalt layer from the base layer.

[0003] At present, asphalt pavement demolition mainly uses excavators. The crushing head is replaced on the output arm of the excavator to separate the road surface, and finally it is loaded onto trucks for transportation.

[0004] The existing Chinese invention patent with publication number CN118958108A is a road repair and cleaning equipment, which belongs to the field of road demolition technology. The equipment is mainly composed of an impact unit group, a cleaning unit group and a collection unit group. The impact unit group crushes the road surface through a swing frame and an impact assembly, and the drive mechanism I drives the swing frame to swing through a crank-connecting rod mechanism. The cleaning unit group uses the cleaning assembly on the fixed frame to remove road debris, and its input end is connected to the drive mechanism I to achieve power sharing. The collection unit group collects the cleaned debris into the collection box through the collection bin and conveying assembly on the chassis. The chassis and the support frame are assembled through a connecting frame, and the moving wheels facilitate the movement of the equipment. In addition, a positioning assembly is provided at the front end of the chassis to support the fixed swing frame. Through an integrated design, the present invention realizes the cleaning operation before road repair, reduces the operating intensity of construction personnel, improves work efficiency, and provides an efficient and convenient solution for road maintenance.

[0005] There are at least the following technical problems in the prior art:

[0006] Impact claws are used to impact and crush the road surface. The reverse impact force is too large during operation, resulting in poor stability of the overall equipment.

[0021] Furthermore, a third power source is installed on both sides of the lower support plate, and the third power source includes a drive motor. The output end of the drive motor is connected to a gearbox, the output end of the gearbox is connected to a transmission shaft, and the transmission shaft is connected to an impact wheel. The transmission shafts of the gearboxes on both sides of the lower support plate are coaxially connected through a coupling.

[0022] Furthermore, the adjustment assembly includes a guide post provided on the support frame, the guide post being slidably connected to the mounting frame, and a preload spring being sleeved on the guide post between the support frame and the mounting frame;

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention reduces the distance between the support frame and the mounting frame by adjusting the components, and scrapes off the inner asphalt layer through the crushing tooth side of the front end, thereby achieving more effective asphalt layer separation. The compression spring component and the impact wheel design of the impact mechanism can enable the compression spring component to effectively absorb and buffer the impact force of the impact wheel when it is not compressed. When the crushing tooth abuts against the asphalt layer, the compression spring component is compressed. At this time, the compression spring component cannot absorb the impact force of the impact wheel, thereby impacting the asphalt pavement, which greatly reduces the recoil force.

[0045] Example 1

[0046] like Figures 1 to 10 As shown, the road surface crushing and recycling equipment of the present invention includes:

[0047] The vehicle body 5 adopts the existing tracked vehicle, and a control panel is provided at the front end. The crushing device is installed at the front end of the vehicle body 5 control panel. A support arm 51 extending forward is also provided at the front end of the vehicle body 5. The support arm 51 is used to provide additional support to the support frame 13, and is used to reduce the pressure of the support frame 13 on the guide column 424, so that the support arm 51 forms a sliding support for the support frame 13.

[0048] A crushing device, used for crushing the asphalt pavement, the crushing device being arranged at the front end of the vehicle body 5;

[0049] like Figure 2 or Figure 3 As shown, the crushing device includes:

[0050] The down-pressing mechanism 1 includes a support frame 13, which is rotatably connected to a crankshaft 12. One end of the crankshaft 12 is connected to a first power source 11. The support frame 13 is hinged with a swingable down-pressing frame 15. A connecting rod 14 is hinged on the crankshaft 12 to drive the down-pressing frame 15 to reciprocate. The other end of the connecting rod 14 is hinged to the down-pressing frame 15. A crushing tooth 18 is provided at the end of the down-pressing frame 15 away from the support frame 13. A bearing seat is provided on the support frame 13 corresponding to the crankshaft 12. The bearing seat is used to install the crankshaft 12. Three groups of bearing seats are arranged here to support each force point, thereby making the crankshaft movement more stable.

[0051] The crank 121 on the crankshaft 12 is hingedly connected to the connecting rod 14 , and the rotation of the crank 121 drives the connecting rod 14 to move. The connecting rod 14 is hingedly connected to the lower pressure frame 15 through the lower end, thereby driving the lower pressure frame 15 to swing.

[0052] The first power source 11 is a reduction motor, which reduces the rotation speed of the crankshaft 12 and facilitates control by the operator.

[0053] like Figure 6 or Figure 7 As shown, the auxiliary mechanism 4 includes a mounting frame 41 set to the front end of the vehicle body 5, the support frame 13 is slidably connected to the mounting frame 41, and an adjustment component 42 is also provided between the support frame 13 and the mounting frame 41. The adjustment component 42 is used to adjust the distance between the support frame 13 and the mounting frame 41. When the lower pressing frame 15 is pressed down to the lowest point, the adjustment component 42 reduces the distance between the support frame 13 and the mounting frame 41.

[0054] Impact mechanism 3: The connecting rod 14 is provided with an impact mechanism 3, which can adjust the length of the connecting rod 14, thereby forming an impact that is transmitted to the crushing teeth 18.

[0055] The lower pressure frame 15 is provided with a spline shaft 16 that cooperates with each other, and the spline shaft 16 is provided with a tooth seat 17 that cooperates with each other. A number of crushing teeth 18 are installed on the tooth seat 17. A fixed cover is connected to the lower pressure frame 15 at the end of the spline shaft 16. The connection with the spline shaft 16 can make the tooth seat 17 more stable and easy to replace. In addition, the spline shaft 16 can be rotated and then reinstalled to effectively adjust the angle of the crushing tooth 18.

[0056] like Figure 3 As shown, the crushing device is also provided with a knocking mechanism 2, and the knocking mechanism 2 is provided on the lower pressure frame 15. The knocking mechanism 2 includes a second power source 21 installed on the lower pressure frame 15. The lower pressure frame 15 is located on the inner side of the crushing teeth 18 and is installed with a rotating drum 22. The second power source 21 is connected to the rotating drum 22, and a breaker hammer 24 is elastically connected to the rotating drum 22.

[0057] The circumferential surface of the drum 22 is provided with a plurality of evenly arranged rows of connecting seats 23 , and a plurality of connecting springs 231 are provided on the connecting seats 23 , and the connecting springs 231 are connected to the breaking hammers 24 .

[0058] During operation, the asphalt blocks scraped off by the crushing teeth 18 are crushed by the crushing hammer 24 to become smaller, making it easier for the crushing teeth 18 to scrape off the asphalt blocks, thereby preventing the asphalt blocks from becoming too large during the scraping process and affecting the life of the scraping teeth.

[0059] like Figure 4 As shown, the impact mechanism 3 includes an upper support plate 33 and a lower support plate 37 respectively arranged in the middle of the connecting rod 14, a sliding column 31 is provided on the lower support plate 37, the sliding column 31 is slidably connected to the upper support plate 33, and an adjusting nut 32 is connected to the position where the sliding column 31 extends out of the upper support plate 33, and an impact plate 36 is also slidably connected to the sliding column 31 between the upper support plate 33 and the lower support plate 37. A number of compression spring assemblies 34 are provided between the impact plate 36 and the upper support plate 33. The compression spring assembly 34 includes spring seats respectively installed on both sides, and compression springs are installed between the spring seats.

[0060] A third power source 38 is provided on the upper and lower end surfaces of the lower support plate 37 . The output end of the third power source 38 is connected to the impact wheel 35 . The impact wheel 35 can make the impact plate 36 reciprocate along the sliding column 31 .

[0061] Sliding columns 31 are provided on both sides of the lower support plate 37. The sliding columns 31 are arranged through the compression spring assemblies 34 on both sides. By using the sliding columns 31 to pass through the compression spring assemblies 34 on both sides, it can not only meet the design requirements of the impact wheel 35 fitting the impact plate 36, but also play a buffering role for the connecting rod 14, thereby greatly simplifying the overall structure of the impact mechanism 3.

[0062] A third power source 38 is installed on both sides of the lower support plate 37. The third power source 38 includes a drive motor. The output end of the drive motor is connected to a gearbox, and the output end of the gearbox is connected to a transmission shaft. The transmission shaft is connected to an impact wheel 35. The transmission shafts of the gearboxes on both sides of the lower support plate 37 are coaxially connected through a coupling.

[0063] like Figure 7 As shown, the adjustment assembly 42 includes a guide column 424 provided on the support frame 13 , the guide column 424 is slidably connected to the mounting frame 41 , and a preload spring 425 is sleeved on the guide column 424 between the support frame 13 and the mounting frame 41 .

[0064] The rigidity of the preload spring 425 can support the lower pressure frame 15. When not in use, the preload spring 425 can effectively support the lower pressure frame 15, so that the crushing teeth 18 are at the upper end.

[0065] A cam 423 is provided on the crankshaft 12, and a pulling seat is correspondingly provided on the mounting frame 41. A pulling column 422 is provided on the pulling seat corresponding to the cam 423. A pulling ring 421 is provided on the outside of the pulling column 422 and the cam 423. During the rotation process, the cam 423 pulls the pulling column 422 to move through the pulling ring 421, thereby reducing the distance between the support frame 13 and the mounting frame 41.

[0066] Here, the pulling ring 421 is used to pull the pulling column 422, with the purpose of using the main power of the third power source 38 to pull the crushing teeth 18, thereby making the driving force stronger.

[0067] like Figure 9 As shown, the crank 121 on the crankshaft 12 is staggered at a certain angle with the cam 423, so that when the crushing tooth 18 reaches the lowest end, the cam 423 pulls the pulling column 422 through the pulling ring 421, thereby reducing the distance between the small support frame 13 and the mounting frame 41, so that the crushing tooth 18 scrapes off the asphalt layer.

[0068] A sliding seat 411 is provided on the mounting frame 41 , and guide posts 424 are slidably connected to the sliding seat 411 . The guide posts 424 are arranged on both sides of the support frame 13 , with at least two groups arranged on one side.

[0069] like Figure 10 As shown, an outer shell 6 is provided on the outside of the crushing device, and the outer shell 6 is divided into a front shell 61 and a rear shell 62. The front shell 61 is provided on the outside of the knocking mechanism 2 to block the flying stones generated by the knocking mechanism 2. The outer shell 62 is provided on the outside of the crushing device as a whole, and the rear shell 62 is installed on the mounting frame 41 by screws.

[0070] Working process or working principle:

[0071] The first part is the equipment structure and power distribution.

[0072] Vehicle body: The tracked chassis (vehicle body 5) provides mobility, and the front console controls equipment operation. Support arms 51 extend to the crushing unit, sharing the pressure from the support frame 13 on the guide column 424 and improving stability.

[0073] Crushing device: It consists of a pressing mechanism 1, an impact mechanism 3, a knocking mechanism 2 and an auxiliary mechanism 4, and each mechanism works in coordination through a power source.

[0074] The vehicle body adopts the reverse method to remove the asphalt layer, which ensures the smooth operation of the crawler chassis.

[0075] The second part is the downward crushing stage.

[0076] Driven by the crankshaft 12: The first power source 11 (reduction motor) drives the crankshaft 12 to rotate, and the crank 121 drives the lower pressure frame 15 to swing back and forth through the connecting rod 14, so that the crushing teeth 18 at the end impact the road surface.

[0077] Adjustment of spline shaft 16: The crushing teeth 18 are connected to the tooth seat 17 through the spline shaft 16, and the angle can be rotated to adjust the service life and adapt to different working conditions.

[0078] Dynamic pulling: The crankshaft 12 synchronously drives the cam 423 to rotate. When the crushing tooth 18 is pressed down to the lowest point, the cam 423 pulls the pulling column 422 through the pulling ring 421, thereby shortening the distance between the support frame 13 and the mounting frame 41, and moving the support frame 13 toward the vehicle body 5, thereby driving the crushing tooth 18 to move, thereby scraping off the asphalt layer.

[0079] The third part is impact-enhanced crushing.

[0080] Function of the impact mechanism 3: The third power source 38 drives the impact wheel 35 to rotate, pushing the impact plate 36 to reciprocate along the sliding column 31. The compression spring assembly 34 absorbs the impact force. When the compression spring assembly 34 is compressed (that is, when the crushing tooth 18 abuts against the asphalt layer), the compression spring assembly 34 releases the impact force, causing an impact on the asphalt layer, which is transmitted to the lower pressure frame 15 through the connecting rod 14 at the lower end, and then transmitted to the crushing tooth 18, thereby enhancing the instantaneous impact strength and improving the crushing efficiency.

[0081] Synchronous buffering: The compression spring assembly 34 buffers the impact force transmitted by the crankshaft 12 and protects the connecting rod 14 structure.

[0082] The fourth part is secondary crushing and adjustment optimization.

[0083] The striking mechanism 2: The second power source 21 drives the drum 22 to rotate, and the connecting seat 23 drives the breaker hammer 24 to swing at high speed through the connecting spring 231, so as to secondary crush the asphalt blocks scooped up by the crushing teeth 18 to prevent large blocks from getting stuck.

[0084] The fifth part is protection.

[0085] Shell protection: The front shell 61 blocks the flying debris generated by the knocking mechanism, and the rear shell 62 covers the entire crushing device and is fixed to the mounting frame 41 by screws for easy maintenance.

[0086] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up and down, does not constitute a limitation of the present invention and is only for the convenience of description.
