On a relatively wet road surface, a scraper moving when the stamping block moves upward can scrape off the soil adhered to the bottom of the stamping block, thereby preventing the soil adhered to the bottom of the stamping block from compacting during the stamping process of the stamping block on the road surface, reducing the possibility that the compacted soil will cause the bottom of the stamping block to be uneven and thus affect the stamping flatness of the road surface, and improving the stamping flatness effect of the stamping block on the road surface; on a dry road surface, the annular tube and the nozzle can spray water mist downward, so the sprayed water mist can form a water curtain around the stamping block during the downward stamping process of the stamping block, and the formed water curtain can block the dust stirred up during the stamping process. At the same time, the dust can be dissolved in the water curtain, reducing the possibility of dust scattering into the air, preventing workers from inhaling dust, and at the same time protecting the environment.

Description

Technical Field

[0001] The present application relates to the technical field of impact roller technology, and in particular to an impact roller device installed on the head of a loader. Background Art

[0002] With the continuous development of society, more and more roads need to be repaired to facilitate people's travel. During the road repair process, stamping equipment is needed to compact the road surface to ensure that the road surface is firm and flat, improve the durability and flatness of the road, and prepare for the subsequent paving of asphalt or cement.

[0003] For example, the highway roadbed impact rolling device with publication number CN220225238U includes: a driving member for driving the rolling assembly to roll the roadbed; a rolling assembly, which is arranged at the lower end of the driving member and is used to roll the roadbed; a support assembly, which is used to quickly support the rolling assembly and facilitate the replacement of the rolling assembly; and a lifting member connected to the output end of the driving member. The rolling assembly includes a rolling plate and a third connecting member detachably connected to the top of the rolling plate. This prior art utilizes the support assembly to achieve the connection between the driving member and the rolling assembly, thereby facilitating the driving member to drive the rolling assembly while facilitating the rapid separation of the two. In addition, the stamping plate is used to cooperate with the rolling plate to roll the roadbed to form a longer rolling plate, so as to adjust the length of the rolling plate according to the construction progress requirements.

[0004] However, the above-mentioned prior art still has some defects when punching the road surface: when the road surface to be punched is wet, mud may adhere to the lower end surface of the pressing plate when punching the road surface in the above-mentioned patent application. If the adhered mud is not removed in time, it may cause the mud to solidify on the lower end surface of the pressing plate during the up and down punching process of the pressing plate. The compacted mud causes the lower end surface of the pressing plate to be uneven, affecting the flatness of the pressing plate on the road surface and affecting the punching effect of the pressing plate on the road surface.

[0005] When the road surface to be stamped is dry, the pressing plate will stir up dust during the stamping process, which will cause the dust to scatter everywhere during the stamping process. Workers are likely to inhale the air containing dust, and the dust scattered everywhere will cause environmental pollution.

[0006] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for road stamping. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following is combined with Figures 1 to 8 This application is described in further detail.

[0032] An embodiment of the present application discloses an impact roller device installed on the head of a loader, which can scrape off the soil adhered during the stamping process; it can also block the dust during the stamping process, reducing pollution to the environment and preventing workers from inhaling dust.

[0033] Example 1:

[0034] See Figure 1 An impact roller device installed on the head of a loader includes two front-to-back symmetrical and L-shaped stamping frames 1, and the opposite surfaces of the vertical sections of the stamping frames 1 are jointly provided with stamping blocks 2 that slide up and down.

[0035] Continue reading Figure 1A horizontal frame 11 is installed between the horizontal sections of the stamping machine frame 1. The upper end surface of the horizontal frame 11 is installed with a front-to-back symmetrical support spring rod 12. The end of the support spring rod 12 away from the horizontal frame 11 is detachably installed with a linkage plate 13 that cooperates with the stamping block 2. The stamping block 2 can drive the linkage plate 13 to move up and down during the up and down movement. The lower end surfaces of the two linkage plates 13 are jointly slid with a scraper 14 that moves left and right, which can scrape the soil on the lower end surface of the stamping block 2.

[0036] When on a relatively wet road surface, the scraper 14 that moves when the punching block 2 moves upward can scrape off the soil adhered to the bottom of the punching block 2, so as to prevent the soil adhered to the bottom of the punching block 2 from becoming hardened during the process of the punching block 2 punching the road surface, reduce the possibility that the hardened soil will cause the bottom of the punching block 2 to be uneven and thus affect the flatness of the road surface, and improve the flatness effect of the punching block 2 on the road surface.

[0037] See Figure 2 An annular tube 21 is installed on the side wall of the stamping block 2 through a connecting protrusion, and a plurality of nozzles 22 are evenly arranged on the lower side of the circumference of the annular tube 21.

[0038] When on a dry road surface, the annular tube 21 and the nozzle 22 can spray water mist downward, so the sprayed water mist can form a water curtain around the stamping block 2 during the downward stamping process of the stamping block 2. The formed water curtain can block the dust stirred up during the stamping process. At the same time, the dust can be dissolved in the water curtain, reducing the possibility of dust scattering into the air, avoiding workers from inhaling dust, and also protecting the environment.

[0039] Replay Figure 1 The upper end surface of the vertical section of the punching machine frame 1 is jointly installed with a traction frame 15, and a traction ring 16 is installed in the middle of the upper end surface of the traction frame 15, which is connected to the external traction equipment. A traction sub-ring 17 is installed in the middle of the upper end surface of the punching block 2, which is connected to the existing loader head. The lower end surface of the horizontal section of the punching machine frame 1 is installed with left-right symmetrical universal wheels 18 to drive the device to move, and the scraper 14 is an L-shaped structure and the upper end of the vertical section of the scraper 14 slides with the lower end surface of the linkage plate 13. The left end surface of the horizontal section of the scraper 14 is set to a structure inclined downward from left to right, which can fit better with the bottom of the punching head, further improving the cleaning effect of the bottom of the punching block 2.

[0040] During specific operation, the traction part of the external traction equipment is fixedly installed on the traction ring 16, and then the existing loader head is fixedly installed on the traction sub-ring 17. The external traction equipment is started and cooperated with the universal wheel 18 to drive the punching machine frame 1 to move. During the movement of the punching machine, the existing loader is started again, and the punching block 2 is driven up and down during the up and down movement of the loader head.

[0041] See Figure 2A liquid storage bag 23 is installed in the middle of the left end face of the punching block 2 for storing water. A liquid inlet 24 is opened at the lower left side of the liquid storage bag 23. The left end face of the impact block and the front and rear sides of the liquid storage bag 23 are both equipped with an air cylinder 25 extending up and down through a fixed protrusion for pumping gas into the liquid storage bag 23. A one-way air inlet valve 26 is installed between the air cylinder 25 and the liquid storage bag 23, so that only gas can be pumped into the liquid storage bag 23, and the gas cannot escape from the liquid storage bag 23 through the gas. A front-to-back symmetrical transition pipe 27 is provided between the lower end face of the liquid storage bag 23 and the annular tube 21 to deliver water to the inside of the annular tube 21. The upper and lower ends of the transition pipe 27 are respectively connected with the liquid storage bag 23 and the annular tube 21.

[0042] The air cylinder 25 is detachably mounted on the punching block 2, and in the starting position, the lower end surface of the telescopic end of the air cylinder 25 is located below the punching block 2. The telescopic end of the air cylinder 25 is provided with a reset spring matched with its fixed end, providing a power source for resetting the telescopic end of the air cylinder 25. The liquid reservoir 23 is made of rubber elastic material, and the external water source is connected to the liquid inlet 24 and water is pumped into the liquid reservoir 23 through an existing water pump (not shown in the figure). When the dry road surface is punched, the linkage plate 13 is removed. At this time, the existing water pump is used to pump water through the inlet. The liquid inlet 24 pumps water into the liquid storage bag 23. At this time, the water fills two-thirds of the liquid storage bag 23. The punching block 2 is driven upward by the existing loader head. When the punching block 2 moves up to a certain height, the existing loader head drives the punching block 2 to move downward. During the downward movement of the punching block 2, the air cylinder 25 first collides with the road surface. At this time, the existing water pump pumps gas into the liquid storage bag 23 through the one-way air inlet valve 26. The gas enters the liquid storage bag 23 and fills the remaining one-third of the volume of the liquid storage bag 23. At this time, the punching block 2 has not yet contacted the road surface.

[0043] The punching block 2 continues to move downward. Before the punching block 2 is in full contact with the road surface, the gas inside the liquid storage bag 23 can drive water to flow into the annular tube 21 through the transition pipe 27. The water flows through the annular tube 21 and flows out from the nozzle 22 to form water mist. The gathered water mist forms a water curtain. The punching block 2 continues to move downward. When the punching block 2 is in full contact with the road surface, the punching block 2 will punch the road surface. During the process of the punching block 2 continuing to move downward, the air cylinder 25 still injects gas into the liquid storage bag 23. At this time, the liquid storage bag 23 expands and accumulates force.

[0044] Therefore, the water curtain formed by the spray of the nozzle 22 can block the dust stirred up during the stamping process. At the same time, the dust can be dissolved in the water curtain, reducing the possibility of dust being scattered into the air, preventing workers from inhaling dust, and also protecting the environment.

[0045] After the above steps are completed, the stamping block 2 moves upward. The dust stirred up when the stamping block 2 moves upward may not have dissipated yet. At this time, the expanded and force-accumulating liquid storage bag 23 can still pump water into the annular tube 21. The water flow continues to pass through the annular tube 21 and flows out from the nozzle 22 to form water mist. Therefore, a water curtain can still be formed during the upward movement of the stamping block 2 to avoid the possibility of dust scattering.

[0046] At the same time, the liquid storage bag 23 can also buffer the gas pumped in by the air cylinder 25, avoiding the possibility that the instantaneous pressure of the punching block 2 in contact with the road surface is too high, the gas pressure inside the liquid storage bag 23 is too high, and the water flow rate inside the transition pipe 27 is too fast or even the transition pipe 27 may burst.

[0047] When on a relatively wet road surface, the air cylinder 25 is removed from the punching block 2 .

[0048] See Figure 3 A fixed frame 131 is installed between the two linkage plates 13. A threaded rod 132 extending left and right is rotatably installed on the fixed frame 131 through a bearing, driving the scraper 14 to move left and right. A linkage protrusion 133 is installed in the middle of the upper end surface of the vertical section of the scraper 14, and the threaded rod 132 is installed on the linkage protrusion 133 through a threaded connection.

[0049] A rack plate 134 extending up and down is mounted on the upper end surface of the horizontal frame 11 , and a meshing gear 135 meshing with the rack plate 134 is mounted on the threaded rod 132 .

[0050] When on a relatively wet road surface, during specific work, when the punching block 2 is moving upward and abuts against the linkage plate 13, the scraper 14 is just level with the bottom of the punching block 2, and the punching block 2 continues to move upward to drive the linkage plate 13 to move upward. At this time, the supporting spring rod 12 is stretched, and the threaded rod 132 moves upward synchronously during the upward movement of the linkage plate 13. During the upward movement of the threaded rod 132, the meshing gear 135 and the rack plate 134 engage with each other to drive the threaded rod 132 to rotate. During the rotation of the threaded rod 132, the scraper 14 is driven to move to the left through the linkage protrusion 133. During the movement of the scraper 14, the soil at the bottom of the punching block 2 can be scraped off, and the scraped soil falls on the road surface.

[0051] See Figure 5 In order to improve the cleaning effect of the scraper 14 on the bottom of the stamping block 2, the toggling claw 143 of the present invention can loosen the soil at the bottom of the stamping block 2. Specifically, a front-to-back symmetrical fixed block 141 is installed on the left side of the lower end surface of the horizontal section of the scraper 14, and a rotating roller 142 is installed between the fixed blocks 141 through a bearing. The rotating roller 142 is provided with multiple groups of toggling claws 143 evenly distributed from front to back, and each group of toggling claws 143 is evenly installed on the rotating roller 142 in the circumferential direction.

[0052] During specific operation, the scraper 14 moves and the pushing claw 143 first contacts the bottom of the punching block 2, and the rotating roller 142 is driven to rotate by an external drive (motor, etc.). The rotating roller 142 drives the pushing claw 143 to rotate during the rotation. During the rotation of the pushing claw 143, the soil at the bottom of the punching block 2 can be stirred before the scraper 14 scrapes off the soil adhered to the bottom of the punching block 2, so that the soil at the bottom of the punching block 2 is loosened, which is convenient for the subsequent scraper 14 to scrape off the soil on the plate 32, and avoid the scraper 14 from breaking due to the hard soil when scraping.

[0053] See Figures 4 to 6 In order to reduce the use of external drive, the linkage shaft 137 of the present invention cooperates with the transmission assembly 130 to drive the rotating roller 142 to rotate. Specifically, an L-shaped fixed vertical frame 136 is provided on the front side of the front linkage plate 13. The horizontal section of the fixed vertical frame 136 is installed on the corresponding linkage plate 13. The vertical section of the fixed vertical frame 136 is rotatably installed with a linkage shaft 137 extending left and right and retractable through a bearing to drive the rotating roller 142 to rotate. Pulleys 138 are installed on the right end of the linkage shaft 137 and the threaded rod 132. The two pulleys 138 are connected by a belt 139. The linkage shaft 137 and the rotating roller 142 are connected to each other through the transmission assembly 130.

[0054] See Figure 5 and Figure 7 The transmission assembly 130 includes a transmission box 1301 fixed on the front fixed block 141, wherein the left side of the linkage shaft 137 is limitedly slidably provided with a linkage connecting shaft 1302 extending left and right. The linkage connecting shaft 1302 can slide left and right inside the linkage shaft 137 along the left and right extension directions, and the left end of the linkage connecting shaft 1302 passes through and is rotatably installed on the left side wall of the transmission box 1301. The front shaft head of the rotating roller 142 passes through the fixed block 141 on the same side, and the front shaft head of the rotating roller 142 passes through and is rotatably installed on the rear side wall of the transmission box 1301, and one end of the rotating roller 142 located inside the transmission box 1301 and one end of the linkage connecting shaft 1302 located inside the transmission box 1301 are both installed with mutually meshing bevel gears 1303.

[0055] During specific operation, the threaded rod 132 rotates through the cooperation between the pulley 138 and the belt 139 to rotate the linkage shaft 137. During the rotation of the linkage shaft 137, the linkage shaft 1302 and the bevel gear 1303 cooperate with each other to drive the rotating roller 142 to rotate. During the rotation of the rotating roller 142, the driving claw 143 can be driven to rotate. When the scraper 14 moves to the left, the linkage shaft 1302 can slide along the inside of the linkage shaft 137 to ensure that the linkage shaft 1302 will not be rigidly broken from the linkage shaft 137 during the movement.

[0056] Therefore, as the universal wheel 18 moves, the above-mentioned action can be repeated to perform the punching process on the road surface.

[0057] Example 2:

[0058] See Figure 8 On the basis of embodiment 1, in order to ensure that the upper end surface of the horizontal section of the scraper 14 does not adhere to mud, the scraping plate 32 designed in the present invention can scrape the mud on the upper end surface of the horizontal section of the scraper 14. Specifically, the upper end surface of the horizontal section of the stamping machine frame 1 is equipped with a connecting spring rod 3, and the upper end surface of the connecting spring rod 3 is equipped with a supporting connecting block 31. The scraping plates 32 that match the upper end surface of the horizontal section of the scraper 14 are installed between the supporting connecting blocks 31.

[0059] When the scraper 14 is driven to move upward by the linkage plate 13, the scraper plate 32 moves upward synchronously. At this time, the connecting spring rod 3 is stretched synchronously. When the stamping block 2 moves downward, the linkage plate 13 moves downward synchronously. During the downward movement of the linkage plate 13, the meshing gear 135 and the rack plate 134 engage with each other to drive the threaded rod 132 to reverse. The threaded rod 132 and the linkage protrusion 133 cooperate with each other to drive the scraper 14 to move right synchronously. During the right movement of the scraper 14, the scraper plate 32 can scrape the soil on the upper end surface of the horizontal section of the scraper 14 to avoid the soil attached to the upper end surface of the horizontal section of the scraper 14 drying and sticking to affect the subsequent scraping effect of the scraper 14 on the bottom of the stamping block 2.

[0060] The implementation principle of the present invention is:

[0061] (1): Fix the traction part of the external traction device to the traction ring 16, then fix the existing loader head to the traction auxiliary ring 17, start the external traction device and cooperate with the universal wheel 18 to drive the punching machine frame 1 to move, and then start the existing loader during the movement of the punching machine. During the up and down movement of the loader head, the punching block 2 is driven to move up and down.

[0062] (2): When stamping a dry road surface, the linkage plate 13 is removed. At this time, water is pumped into the liquid reservoir 23 through the liquid inlet 24 by the existing water pump. At this time, the water fills two-thirds of the liquid reservoir 23. The punching block 2 is driven upward by the existing loader head. When the punching block 2 moves up to a certain height, the existing loader head drives the punching block 2 downward. During the downward movement of the punching block 2, the air cylinder 25 first collides with the road surface. At this time, the existing water pump pumps gas into the liquid reservoir 23 through the one-way air inlet valve 26. The gas enters the liquid reservoir 23 and fills the remaining one-third of the volume of the liquid reservoir 23. At this time, the punching block 2 has not yet contacted the road surface.

[0063] (3): Before the punching block 2 is in full contact with the road surface, the gas inside the liquid storage bag 23 can drive water to flow into the annular tube 21 through the transition pipe 27. The water flows through the annular tube 21 and flows out from the nozzle 22 to form water mist. The gathered water mist forms a water curtain. The punching block 2 continues to move downward. When the punching block 2 is in full contact with the road surface, the punching block 2 will punch the road surface.

[0064] (4): The rotating roller 142 drives the moving claw 143 to rotate during the rotation. During the rotation of the moving claw 143, the soil at the bottom of the punching block 2 can be stirred before the scraper 14 scrapes off the soil adhered to the bottom of the punching block 2, so that the soil at the bottom of the punching block 2 is loosened.

[0065] (5): When the punch block 2 is moving upward and abuts against the linkage plate 13, the scraper 14 is just level with the bottom of the punch block 2. The punch block 2 continues to move upward and drives the linkage plate 13 to move upward. At this time, the supporting spring rod 12 is stretched. During the upward movement of the linkage plate 13, the threaded rod 132 moves upward synchronously. During the upward movement of the threaded rod 132, the meshing gear 135 and the rack plate 134 engage with each other to drive the threaded rod 132 to rotate. During the rotation of the threaded rod 132, the scraper 14 is driven to move to the left through the linkage protrusion 133. During the movement of the scraper 14, the soil at the bottom of the punch block 2 can be scraped off.
