[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0032] like Figures 1 to 4As shown, a road surface maintenance crack sealing device according to an embodiment of the present invention includes a base plate 1, a storage box 11 is provided on the top surface of the base plate 1, a liquid pump 12 is provided on one side of the storage box 11, the input end of the liquid pump 12 is connected to the storage box 11; a transition box 13 is connected to the output end of the liquid pump 12, a hose 14 is connected to the side of the transition box 13, and a nozzle 15 is provided at the end of the hose 14 away from the transition box 13.
[0033] A stone box 2 is provided on the top surface of the substrate 1 and on one side of the transition box 13. A first conveying pipe 21 is provided through the side of the stone box 2. A horizontal spiral rod is provided inside the first conveying pipe 21, and the end of the horizontal spiral rod is connected to the output end of the first motor. A connecting pipe 23 is provided through the surface of the first conveying pipe 21 outside the transition box 13 and is connected to the top surface of the transition box 13. A receiving funnel 22 is provided through the surface of the first conveying pipe 21 inside the transition box 13. A feeding assembly is provided on one side of the receiving funnel 22.
[0034] In this embodiment of the invention, a drive wheel is provided on the side of the substrate 1, which moves the substrate 1 to the location of the road crack. A drive rod is provided on the surface of the nozzle 15, and the operator moves the nozzle 15 so that the nozzle nozzle 15 is pointing into the crack. Then, the pump 12 is started, which pumps the emulsified asphalt in the storage tank 11 into the transition tank 13. Then, it is injected into the crack through the hose 14 and the nozzle 15. At the same time, the first motor is started, which drives the horizontal screw rod to rotate. Simultaneously, the feeding component transfers the crushed stone in the stone box 2 to the receiving funnel 22. Then, it is injected into the transition tank 13 through the first conveying pipe 21 and the connecting pipe 23. The crushed stone is injected into the crack along with the emulsified asphalt through the transition tank 13. It should be noted that the size of the crushed stone is small, so it will not cause the hose 14 and the nozzle 15 to become blocked. As it enters the crack with the emulsified asphalt, the repair effect on the crack is improved.
[0035] The feeding assembly includes a second feeding pipe 3, inside which a vertical screw rod is installed. The end of the vertical screw rod is connected to the output end of a second motor. A feed hole is opened on the side of the second feeding pipe 3. A discharge pipe 31 is installed through the side of the second feeding pipe 3 above the feed hole. The opening of the discharge pipe 31 points to the opening of the receiving funnel 22. During feeding, the second motor is started, and the second motor drives the vertical screw rod to rotate. The crushed stone inside the stone box 2 enters the interior through the feed hole opened on the side of the second feeding pipe 3, and then is transported to the receiving funnel 22 through the discharge pipe 31. The entire feeding process can realize the stable conveying of crushed stone, which is conducive to the stable entry of stone into the transition box 13.
[0036] A filter plate 32 is installed between the discharge pipe 31 and the receiving funnel 22, and a support frame is installed between the filter plate 32 and the first conveying pipe 21. The top surface of the filter plate 32 has multiple filter holes. When the material falls from the outlet of the discharge pipe 31 into the receiving funnel 22, it needs to be filtered by the filter plate 32. The filter plate 32 filters out larger stones through the filter holes to prevent larger stones from entering the transition box 13 and causing blockage of the hose 14.
[0037] Inside the stone hopper 2, below the filter plate 32, there is a support plate 4. A vibrator 41 is installed on the top surface of the support plate 4, and the output end of the vibrator 41 points to the bottom surface of the filter plate 32. The filter plate 32 is inclined relative to the horizontal plane. When in use, the vibrator 41 is started, and the output end of the vibrator 41 hits the bottom surface of the filter plate 32. Larger stones filtered by the filter plate 32 are vibrated and fall off, preventing larger stones from clogging the filter holes.
[0038] A receiving plate 42 is provided at the lower end of the filter plate 32. The receiving plate 42 is installed on the surface of the first conveying pipe 21 and includes a vertical part and an inclined part. Stones falling from the top surface of the filter plate 32 are first blocked by the vertical part and then slide down through the inclined part. When the inclined filter plate 32 vibrates, larger stones move towards the lower end of the filter plate 32, are first blocked by the vertical part, and then slide down through the inclined part. The vibration of the filter plate 32 will cause deformation, which will intermittently change the distance between the end of the filter plate 32 near the receiving plate 42 and the inclined part of the receiving plate 42. The stones that enter between the end of the filter plate 32 and the inclined part of the receiving plate 42 are crushed and then fall off, making it convenient for continued use.
[0039] like Figures 5 to 6 As shown, a rectangular hole 24 is provided on the side of the stone box 2, and a rectangular spray plate 25 is inserted into the inside of the rectangular hole 24. The nozzle of the rectangular spray plate 25 points towards the second conveying pipe 3. An air pump 26 is installed on the side of the stone box 2. A conduit is provided between the output end of the air pump 26 and the rectangular spray plate 25. When in use, the air pump 26 is started, and the air pump 26 injects air into the rectangular spray plate 25 through the conduit. Then, the air is sprayed out through the nozzle towards the second conveying pipe 3, thereby driving the crushed stone inside the stone box 2 into the feed hole, further optimizing the feeding stability of the feeding component.
[0040] like Figures 7 to 9As shown, a pair of partitions 51 are inserted through the side of the connecting pipe 23. The end of the partition 51 outside the connecting pipe 23 is provided with a first telescopic rod 5. The first telescopic rod 5 is installed on the top surface of the base plate 1 and its output end is connected to the end of the partition 51. When the crushed stone enters the interior of the connecting pipe 23, the upper partition 51 receives the stone. Then, the first telescopic rod 5 drives the upper partition 51 to detach from the connecting pipe 23, and the crushed stone falls onto the top surface of the lower partition 51. After that, the upper partition 51 is reset, the lower partition 51 detaches from the connecting pipe 23, and the crushed stone on the top surface of the lower partition 51 falls into the transition box 13. This prevents the continuous connection between the connecting pipe 23 and the transition box 13 from causing the emulsified asphalt in the transition box 13 to flow back into the first conveying pipe 21 through the connecting pipe 23. This also prevents the emulsified asphalt from adhering and accumulating in the first conveying pipe 21, ensuring the stability of the crushed stone conveying.
[0041] The end of the partition 51 away from the first telescopic rod 5 is set in a pointed shape; when the partition 51 is reset, the gravel between the end and the inner wall of the connecting pipe 23 is squeezed and separated by the pointed tip, which can prevent the end of the partition 51 from being blocked by gravel when it is reset and moved.
[0042] A filter screen 6 is provided on the inner bottom surface of the transition box 13, and a second telescopic rod 61 is provided on the bottom surface of the base plate 1. The output end of the second telescopic rod 61 extends into the interior of the transition box 13 and its top end is connected to the bottom surface of the filter screen 6. The gravel entering the transition box 13 may settle to the bottom. When in use, the second telescopic rod 61 is activated, and the second telescopic rod 61 intermittently lifts the filter screen 6 upward, so that the gravel that has settled on the top surface of the filter screen 6 is transferred to the middle position of the transition box 13, which is conducive to the flow of emulsified asphalt carrying the gravel to the hose 14; thereby preventing the gravel from settling and accumulating in the transition box 13.
[0043] like Figure 2 As shown, a sealing plate 7 is provided at the nozzle of the nozzle 15, a connecting frame 72 is provided on the side of the sealing plate 7, and a third telescopic rod 71 is provided on the side of the nozzle 15. The output end of the third telescopic rod 71 is connected to the end of the connecting frame 72 away from the sealing plate 7. When the grouting is finished, the third telescopic rod 71 is activated. The third telescopic rod 71 drives the sealing plate 7 to move through the connecting frame 72 to block the nozzle of the nozzle 15, preventing leakage of emulsified asphalt from the hose 14 and the nozzle 15.
[0044] During operation, a drive wheel is provided on the side of the substrate 1, which moves the substrate 1 to the location of the road crack. A drive rod is provided on the surface of the nozzle 15, and the operator moves the nozzle 15 so that the nozzle nozzle 15 is pointed into the crack. Then, the pump 12 is started, which pumps the emulsified asphalt in the storage tank 11 into the transition tank 13, and then injects it into the crack through the hose 14 and the nozzle 15. At the same time, the first motor is started, which drives the horizontal screw rod to rotate. Simultaneously, the feeding component transfers the crushed stone in the stone box 2 to the receiving drain. The material is fed into the hopper 22, and then injected into the transition box 13 through the first conveying pipe 21 and the connecting pipe 23. The crushed stone is injected into the crack along with the emulsified asphalt through the transition box 13. It should be noted that the crushed stone is small in size and will not cause blockage of the hose 14 and the nozzle 15. As it enters the crack along with the emulsified asphalt, the repair effect on the crack is improved. During feeding, the second motor is started, which drives the vertical screw to rotate. The crushed stone located inside the stone hopper 2 enters the interior through the feed hole on the side of the second conveying pipe 3, and then passes through the discharge pipe 3. 1. The material is transported to the receiving funnel 22. The entire feeding process can achieve stable conveying of the crushed stone, which is conducive to the stable entry of the stone into the transition box 13. When the crushed stone falls from the outlet pipe 31 into the receiving funnel 22, it needs to be filtered by the filter plate 32. The filter plate 32 filters out the larger crushed stone through the filter holes, preventing the larger crushed stone from entering the transition box 13 and causing blockage of the hose 14. When in use, the vibrator 41 is started. The output end of the vibrator 41 impacts the bottom surface of the filter plate 32, and the larger crushed stone filtered by the filter plate 32 is vibrated. The filter plate 32 is designed to prevent large stones from clogging the filter holes. When the inclined filter plate 32 vibrates, larger stones move towards the lower end of the filter plate 32. They are first blocked by the vertical part and then slide down through the inclined part. The vibration of the filter plate 32 causes deformation, which intermittently changes the distance between the end of the filter plate 32 near the receiving plate 42 and the inclined part of the receiving plate 42. The stones that enter between the end of the filter plate 32 and the inclined part of the receiving plate 42 are crushed and then fall off, making it easier to continue using the filter plate.
[0045] When in use, the jet pump 26 is activated, injecting air into the rectangular spray plate 25 through a conduit, and then spraying it out through the nozzle towards the second conveying pipe 3, thereby driving the crushed stone inside the stone box 2 into the feed hole, further optimizing the feeding stability of the feeding component. When the crushed stone enters the connecting pipe 23, the upper baffle 51 receives the stone, and then the first telescopic rod 5 drives the upper baffle 51 to detach from the connecting pipe 23, and the crushed stone falls onto the top surface of the lower baffle 51. After that, the upper baffle 51 is reset, the lower baffle 51 detaches from the connecting pipe 23, and the crushed stone on the top surface of the lower baffle 51 falls into the transition box 13, preventing the emulsified asphalt in the transition box 13 from flowing back into the first conveying pipe 21 through the connecting pipe 23 due to continuous communication between the connecting pipe 23 and the transition box 13, thus preventing the flow of emulsified asphalt into the first conveying pipe 21 as it flows through the first conveying pipe 21. The emulsified asphalt adheres and accumulates, ensuring the stability of the crushed stone conveying. When the partition 51 is reset, the crushed stone between its end and the inner wall of the connecting pipe 23 is squeezed and separated by the tip, preventing the end of the partition 51 from being blocked by crushed stone during reset. The crushed stone entering the transition box 13 may settle to the bottom. When in use, the second telescopic rod 61 is activated, which intermittently lifts the filter screen 6 upward, so that the crushed stone settled on the top surface of the filter screen 6 is transferred to the middle position of the transition box 13, which is conducive to the flow of emulsified asphalt carrying the crushed stone to the hose 14. This prevents the crushed stone from settling and accumulating in the transition box 13. When the grouting is finished, the third telescopic rod 71 is activated. The third telescopic rod 71 drives the sealing plate 7 to move through the connecting frame 72 to block the nozzle of the nozzle 15, preventing the emulsified asphalt in the hose 14 and nozzle 15 from leaking.
