Description

Technical Field

[0001] The present application relates to the field of plastic track paving, and in particular to a paving device for composite polyurethane track surface construction. Background Art

[0002] The plastic track is made of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. After mixing, it is paved by paving equipment.

[0003] In the related technology, a plastic track paver is disclosed, which includes a moving trolley, a movable component and a material grinding piece, and the movable component is connected to the moving trolley, and the material grinding piece is installed on the movable component. The movable component is used to drive the material grinding piece to move. The plastic track paver also includes: an adhesion material cleaning structure, which is arranged on the movable component and contacts with the surface of the material grinding piece, and is used to clean the material adhered to the surface of the material grinding piece when the material grinding piece is not in use.

[0004] The above-mentioned related technologies have the following defects: the adhesion material cleaning structure scrapes off the material sticking to the surface of the grinding piece, and the material falls onto the completed runway under the action of gravity. A secondary cleaning is required later to clean the material fallen on the completed runway, which increases the construction steps, thereby reducing the efficiency of runway paving, so it needs to be improved. Summary of the invention

[0005] In order to improve the problem that the runway needs to be cleaned after paving, resulting in low efficiency of runway paving, the present application provides a paving device for composite polyurethane runway surface construction.

[0006] The present application provides a composite polyurethane runway surface construction paving device using the following technical solutions:

[0007] A paving device for composite polyurethane runway surface construction comprises a mobile body, a material storage box and a pressure roller, the material storage box is fixedly mounted on the mobile body, the side wall of the material storage box is connected to a discharge pipe, the discharge pipe is located in the forward direction of the pressure roller, the end of the discharge pipe away from the material storage box is opened and faces the ground, the pressure roller is rotatably connected to the mobile body, a material holding box is vertically arranged on the mobile body, a feed port is penetrated through the side wall of the material holding box, a cleaning mechanism is arranged on the material holding box, the cleaning mechanism comprises an abutment plate and a torsion spring, one end of the abutment plate is connected to the inner wall of the material holding box through the torsion spring, and the other end abuts against the side wall of the pressure roller, and the side of the abutment plate away from the torsion spring is inclined toward the direction close to the pressure roller.

[0008] By adopting the above technical solution, when the mobile vehicle body moves forward, the material falls from the storage box through the discharge pipe to the ground, and then the pressure roller moves to the material on the ground and pushes and crushes the material, so that the height of the crushed material from the ground is constant, and the side of the crushed material away from the ground is on the same horizontal plane, that is, the material is evenly spread on the ground, thereby realizing the paving of the runway. When the material is being squeezed, it is very easy to stick to the pressing roller. When the pressing roller rotates, the side of the abutment plate away from the torsion spring slides against the side wall of the pressing tube, thereby scraping the material on the pressing roller to the side of the abutment plate away from the ground. The side of the abutment plate away from the ground plays a guiding role, so that the material on the abutment plate moves along the side wall of the abutment plate through the feed port toward the material holding box until the material on the abutment plate falls into the material holding box, so that the material scraped from the pressing roller is not easy to fall on the paved runway, and there is no need to clean the paved runway, which reduces the construction steps and improves the construction efficiency of runway paving.

[0009] Optionally, a cleaning assembly is connected to the material holding box, and the cleaning assembly includes a filter screen and a connecting pipe, the circumferential side wall of the filter screen is fixedly connected to the inner wall of the material holding box, the side of the filter screen away from the bottom wall of the material holding box and the side of the feed port close to the bottom wall of the material holding box are on the same horizontal plane, and a discharge port is provided through the side wall of the material holding box, the discharge port and the feed port are symmetrical with respect to the central axis of the material holding box, and the discharge port is connected to the discharge pipe through the connecting pipe.

[0010] By adopting the above technical scheme, when the press roller rotates, the abutment plate scrapes the material on the press roller into the material holding box and drops it onto the filter net. Then the abutment plate continuously scrapes new material into the material holding box, so that the material is continuously accumulated on the filter net, and pushes the material on the filter net away from the feed port to move toward the discharge pipe, so that the material on the filter net enters the discharge pipe through the connecting pipe, and then is discharged to the ground through the discharge pipe, which is located in the forward direction of the press roller, thereby realizing the recycling of materials, reducing material waste, and saving more energy.

[0011] Optionally, a pushing assembly is connected to the material box, and the pushing assembly includes a pushing block and a moving rod. The pushing block is slidably connected to the material box, and the side of the pushing block close to the ground abuts against the side of the filter screen away from the ground. The moving rod is fixedly connected to the pushing block, the moving rod is vertically arranged, and the end of the moving rod away from the ground extends out of the material box, and the moving rod is slidably connected to the material box.

[0012] By adopting the above technical scheme, when the abutment plate scrapes the material on the side wall of the pressing roller into the material holding box, the material accumulates on the filter screen, and the pushing block moves along the filter screen under the drive of the moving rod, so that the side of the pushing block close to the connecting pipe abuts against the material on the filter screen, and drives the material to move on the filter screen toward the connecting pipe until the material enters the connecting pipe through the discharge port, so that it is not easy for too much material to accumulate on the filter screen, but overflows from the material holding box through the feed port, thereby reducing the possibility of material falling onto the paved runway, eliminating the need to clean the paved runway, reducing the construction steps, and thus improving the construction efficiency of runway paving.

[0013] Optionally, the material holding box is provided with an adjusting mechanism for controlling the opening and closing of the feed port and the discharge port, the mobile body is connected to a water holding tank, the bottom of the material holding box is connected with a water inlet pipe and a water outlet pipe, the water inlet pipe and the water outlet pipe are respectively connected to the water holding tank, the water inlet pipe is provided with a water inlet pump, and the water outlet pipe is provided with a water outlet pump.

[0014] By adopting the above technical solution, when the materials on the pressing roller are scraped into the material holding box by the abutment plate, the adjusting mechanism is moved so that the feed port and the discharge port are both in a closed state, and then the water inlet pump is started so that the water in the water holding box enters the material holding box through the water inlet pipe, so that the materials in the material holding box are immersed in water. The water inlet pump is turned off, and then the moving rod is moved to move the pusher block, which eventually stops moving at the end of the filter screen close to the feed port. During the movement, the pusher block moves the water in the material holding box, so that the water in the material holding box generates a water flow, and the materials in the material holding box are dispersed under the action of the water flow, so that the materials are not easily adhered to the filter screen and the inner wall of the material holding box, and at the same time, the materials will not accumulate on the filter screen, which is convenient for the pusher block to push the materials on the filter screen;

[0015] Then start the water outlet pump to recycle the water in the material storage box into the water storage box through the water outlet pipe. The suction of the water outlet pump also drives the materials to move in a concentrated direction close to the filter screen, so that the materials are not easy to adhere to the inner wall of the material storage box. The filter screen plays a barrier role, so that the materials in the material storage box will only exist on the side of the filter screen away from the ground. When the water level in the material storage box is lower than the filter screen, the materials settle on the filter screen. At this time, the materials are not easy to accumulate on one part of the filter screen. The adjustment mechanism is used to open the feed port and the discharge port, and then the moving rod is toggled so that the push block pushes the materials on the filter screen to move in the direction close to the connecting pipe, so that the materials on the filter screen enter the discharge pipe through the connecting pipe, and then are discharged to the ground in the forward direction of the pressing roller through the discharge pipe. When the water enters the material storage box, it also cleans the materials in the material storage box, so that the materials that finally enter the discharge pipe for recycling are not easy to be mixed with foreign objects, thereby improving the quality of runway construction.

[0016] Optionally, the adjustment mechanism includes a driving assembly and an adjusting assembly, both of which are connected to the material holding box, and the driving assembly is connected to the adjusting assembly via a rotating rack. The driving assembly rotates to drive the rotating rack to move, thereby driving the adjusting assembly to open or close the feed port and the discharge port.

[0017] By adopting the above technical scheme, when the materials on the pressing roller are scraped into the material holding box by the abutment plate, the driving assembly is rotated to move the rotating rack, thereby driving the adjustment assembly to move, blocking the feed port and the discharge port, so that after the water in the water tank passes into the material holding box, the water is not easy to leak out of the material holding box through the feed port and the discharge port, thereby achieving the goal of completely immersing the materials in the material holding box in water, which is convenient for breaking up the materials.

[0018] Optionally, the driving assembly includes a rotating gear and two movable plates, the rotating gear is rotatably connected to the material box, the two movable plates are axially symmetrical about a vertical line passing through the center of the rotating gear, the movable plate is slidably connected to the material box through the rotating rack, the rotating rack is meshed with the rotating gear, a movable hole is provided on the movable plate, the end of the movable hole close to the ground is inclined away from the rotating gear, and the adjustment assembly is inserted in the movable hole and slides in the movable hole.

[0019] By adopting the above technical solution, when the materials on the pressing roller are scraped into the material storage box by the abutment plate, the rotating gear is rotated so that the two rotating racks drive the moving plate to move simultaneously in the direction away from the center of the rotating gear. The moving hole guides the adjustment component so that the adjustment component can only move along the track of the moving hole, so that the two adjustment components move simultaneously until the adjustment component blocks the feed port and the discharge port. At this time, the rotating gear stops rotating so that the rotating rack will not drive the moving plate to move, so that the feed port and the discharge port remain in a closed state, and the operation is convenient.

[0020] Optionally, the adjustment assembly includes two baffles, which are symmetrical about the central axis of the material holding box, one of the baffles is used to block the feed port, and the other baffle is used to block the discharge port. The material holding box is provided with a guide groove for inserting the baffle along the vertical direction, one end of the baffle is inserted in the movable hole and slides in the movable hole to drive the baffle to slide in the guide groove.

[0021] By adopting the above technical solution, when the materials on the pressing roller are scraped into the material storage box by the abutment plate, the rotating gear is rotated so that the two rotating racks drive the moving plate to move in the direction away from the center of the rotating gear at the same time, and the inner wall of the moving hole abuts against the side wall of the baffle, which guides the baffle and makes the baffle move along the track of the moving hole. The inner wall of the guide groove abuts against the side wall of the baffle, which limits the baffle so that the baffle can only move in the vertical direction, so that the baffle finally moves in the guide groove in the direction away from the ground until one of the baffles blocks the feed port and the other baffle blocks the discharge port, so that after the water in the water tank passes into the material storage box, the water is not easy to leak out of the material storage box through the feed port and the discharge port, so that the materials in the material storage box are fully immersed in water, which is convenient for breaking up the materials.

[0022] Optionally, the mounting frame is connected to the mobile vehicle body via a lifting drive member, and the lifting drive member is used to drive the mounting frame to move towards or away from the ground. A rotating rod is passed through the pressure roller, and the rotating rod is coaxially fixed with the pressure roller. The rotating rod is rotatably connected to the mounting frame, and a rotating mechanism is provided on the rotating rod. The rotating mechanism includes an extrusion assembly and a rotating assembly, and the extrusion assembly is sleeved in the rotating rod, and the rotating assembly is coaxially fixed with the rotating gear. The extrusion assembly is connected to the rotating assembly via an extrusion plate. The movement of the extrusion assembly drives the extrusion plate to move, thereby driving the rotating assembly to rotate.

[0023] By adopting the above technical solution, when the nip roller continuously rolls and pushes the material, the material will also stick to the nip roller while being squeezed. When there is a lot of material attached to the nip roller, the height of the nip roller from the ground is reduced, so that the thickness of the paved material changes, affecting the quality of the runway. At this time, the lifting drive is started to lift the nip roller away from the ground until the nip roller moves to the feed port. At this time, the extrusion assembly is squeezed in the direction close to the extrusion plate, so as to push the extrusion plate to move, and then the rotating assembly is rotated, that is, the rotating gear is driven to rotate, so as to realize the movement of the baffle, so that the feed port and the discharge port are in an open state. Then, the abutment plate extends out of the feed port under the action of the torsion spring and abuts against the side wall of the nip roller. Then, the extrusion assembly is used to drive the rotating rod to rotate, so that the nip roller rotates, and the abutment plate abuts and slides on the side wall of the nip roller, so as to facilitate the scraping of the material sticking on the side wall of the nip roller onto the abutment plate.

[0024] Optionally, the extrusion assembly includes an extrusion rod, a return spring and a push rod, a rotation hole is provided at one end of the rotating rod, the extrusion rod is adapted to be inserted in the rotation hole and slide in the rotation hole, the extrusion rod is coaxial with the rotating rod, one end of the return spring is connected to the rotating rod, and the other end is connected to the extrusion rod, the push rod is inserted in the rotation hole and is slidably connected to the rotating rod, the extrusion plate is connected to the mobile vehicle body through the extrusion spring, and is located at the end of the extrusion rod away from the push rod.

[0025] By adopting the above technical solution, when the pressure roller moves to the feed port, the push rod is squeezed in the direction close to the extrusion plate until the push rod abuts against the extrusion rod, and the reset spring is compressed to drive the extrusion rod to move in the direction close to the extrusion plate until the extrusion rod abuts against the extrusion plate, and the push rod continues to move. The compression of the extrusion spring causes the extrusion rod to drive the extrusion plate to move, thereby causing the rotating assembly to rotate, that is, the rotating gear to rotate, and then the rotating rack drives the baffle to move in the direction close to the ground, thereby realizing the opening of the feed port and the discharge port. When the materials on the side wall of the pressure roller have been scraped into the material storage box, the force of the extrusion push rod is removed, and the reset spring restores its deformation, causing the extrusion rod to move in the direction away from the extrusion plate, and the extrusion plate loses the extrusion force. The extrusion spring restores its deformation, causing the extrusion plate to reset, thereby causing the rotating assembly to drive the rotating gear to reverse, and the feed port and the discharge port can be closed, which is convenient to operate.

[0026] Optionally, the rotating assembly includes a rotating block and a rotating rod, the rotating block is fixedly connected to the extrusion plate, the rotating rod is rotatably connected to the mobile body, the side wall of the rotating rod is circumferentially provided with a rotating groove, the rotating block is inserted in the rotating groove, and moves in the rotating groove to drive the rotating rod to rotate.

[0027] By adopting the above technical scheme, when the extrusion rod compresses the extrusion spring and drives the extrusion plate to move, the rotating block moves along the direction of the central axis of the rotating rod, and the inner wall of the rotating groove abuts against the inner wall of the rotating block, guiding the rotating block, so that the rotating block moves along the trajectory of the rotating groove, thereby causing the rotating rod to rotate around the central axis of the rotating rod. When the extrusion rod moves away from the extrusion plate, the extrusion spring restores its deformation and pushes the extrusion plate toward the direction of the pressing roller, so that the rotating block moves along the direction of the central axis of the rotating rod toward the direction of the pressing roller, thereby causing the rotating rod to drive the rotating gear to reverse, and the operation is convenient.

[0028] In summary, the present application includes at least one of the following beneficial effects:

[0029] 1. When the moving vehicle body is moving forward, the material falls from the storage box through the discharge pipe to the ground. Then the pressing roller moves to the material on the ground and pushes and rolls the material so that the height of the rolled material from the ground is constant and the side of the rolled material away from the ground is on the same horizontal plane, that is, the material is evenly spread on the ground to achieve the paving of the runway. While squeezing the material, the material is very easy to stick to the pressing roller. When the pressing roller rotates, the cleaning component slides against the side wall of the pressing roller, thereby scraping the material off the pressing roller and entering the material storage box through the feed port along the cleaning component, so that the material is not easy to fall on the paved runway, and there is no need to clean the paved runway, which reduces the construction steps and improves the construction efficiency of runway paving. The cleaning component continuously scrapes the material into the material holding box, so that the subsequent material entering the material holding box pushes the material in the material holding box away from the feed port to move toward the discharge pipe until it enters the discharge pipe through the connecting pipe, and then is discharged to the ground through the discharge pipe, which is located in the forward direction of the pressing roller, so as to realize the recycling of materials, reduce material waste, and save more energy;

[0030] 2. When the press roller rotates, the side of the abutment plate away from the torsion spring abuts and slides on the side wall of the press tube, thereby scraping the material on the press roller to the side of the abutment plate away from the ground. The side of the abutment plate away from the ground plays a guiding role, so that the material on the abutment plate moves along the side wall of the abutment plate through the feed port toward the direction close to the material holding box until the material on the abutment plate falls onto the filter net. The abutment plate continuously scrapes new material into the material holding box, so that the material continuously accumulates on the filter net, and pushes the material on the filter net away from the feed port to move toward the direction close to the discharge pipe, so that the material on the filter net enters the discharge pipe through the connecting pipe, and then is discharged to the ground through the discharge pipe, which is located in the forward direction of the press roller, thereby realizing the recycling of materials, reducing material waste, and saving more energy.

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The present application embodiment discloses a paving device for composite polyurethane runway surface construction. Figure 1 and Figure 2 The paving device for composite polyurethane runway surface construction includes a mobile body 1, a material storage box 2 and a press roller 3. The material storage box 2 is used to store materials used for runway paving, and the outer bottom wall of the material storage box 2 is welded and fixed on the mobile body 1. The side wall of the material storage box 2 is connected with a discharge pipe 4, and the end of the discharge pipe 4 away from the material storage box 2 is open and aligned with the ground. The mobile body 1 is fixedly connected with a lifting drive member 10 by bolts. In the embodiment of the present application, the lifting drive member 10 adopts a cylinder, and the output end of the lifting drive member 10 is fixedly connected with a mounting frame 14, and the mounting frame 14 is slidably connected to the mobile body 1. A rotating rod 11 is passed through the press roller 3, and the rotating rod 11 is coaxial with the press roller 3 and is welded and fixed to the press roller 3. Both ends of the rotating rod 11 are rotatably connected to the mounting frame 14.

[0039] As the mobile body 1 moves forward, the material falls from the storage box 2 to the ground through the discharge pipe 4, and then the pressing roller 3 moves to the material on the ground and pushes and crushes the material so that the height of the crushed material from the ground is constant, and the side of the crushed material away from the ground is on the same horizontal plane, that is, the material is evenly spread on the ground to achieve the paving of the runway. When the thickness of the runway paving changes, the lifting drive 10 is started to drive the mounting frame 14 to move, and the distance from the pressing roller 3 to the ground is adjusted to change the thickness of the runway surface layer.

[0040] Reference Figure 1 and Figure 3 A material holding box 5 is welded and fixed on the mobile body 1. The material holding box 5 is vertically arranged and located between the pressing tube and the discharge tube 4. A feed port 51 and a discharge port 52 are penetrated through the side wall of the material holding box 5. The feed port 51 and the discharge port 52 are axially symmetrical with the central axis of the material holding box 5. The feed port 51 faces the pressing roller 3, and the discharge port 52 faces the discharge tube 4, and the discharge port 52 is connected with the discharge tube 4 through the connecting tube 15.

[0041] Reference Figure 1 and Figure 3 A cleaning mechanism 6 is provided on the material holding box 5, and the cleaning mechanism 6 includes an abutment plate 612 and a torsion spring 611. One end of the torsion spring 611 is welded and fixed to the inner wall of the side of the feed port 51 close to the ground, and the other end is welded and fixed to the side of the abutment plate 612 close to the ground. A rotating shaft is passed through the torsion spring 611, and the rotating shaft is rotatably connected to the inner wall of the material holding box 5. The torsion spring 611 is used to flip the abutment plate 612 in a direction away from the central axis of the material holding box 5, and the side of the abutment plate 612 away from the torsion spring 611 is tilted in a direction close to the pressing roller 3.

[0042] Reference Figure 1 and Figure 3 A cleaning assembly 61 is connected to the material holding box 5, and the cleaning assembly 61 includes a filter screen 613. The circumferential side wall of the filter screen 613 is welded and fixed to the inner wall of the material holding box 5, and the sides of the feed port 51 and the discharge port 52 close to the ground are on the same horizontal plane as the side of the filter screen 613 away from the ground.

[0043] When the nip roller 3 continuously crushes and pushes the material, the material will stick to the nip roller 3 while being squeezed. When there is a lot of material attached to the nip roller 3, the height of the nip roller 3 from the ground is reduced, thereby changing the thickness of the paved material and affecting the quality of the runway. At this time, the lifting drive member 10 is started to lift the pressure roller 3 away from the ground until the pressure roller 3 moves to the feed port 51. The abutment plate 612 extends out of the feed port 51 under the action of the torsion spring 611 and abuts against the side wall of the pressure roller 3. Then the pressure roller 3 is rotated so that the side of the abutment plate 612 away from the torsion spring 611 abuts and slides on the side wall of the pressure tube, thereby scraping the material on the pressure roller 3 to the side of the abutment plate 612 away from the ground. The side of the abutment plate 612 away from the ground plays a guiding role, so that the material on the abutment plate 612 moves along the side wall of the abutment plate 612 through the feed port 51 toward the direction close to the material holding box 5 until the material on the abutment plate 612 falls onto the filter screen 613. The abutment plate 612 continuously scrapes new materials into the material holding box 5, so that the materials are continuously accumulated on the filter screen 613, and pushes the materials on the filter screen 613 away from the feed port 51 to move toward the discharge pipe 4, so that the materials on the filter screen 613 enter the discharge pipe 4 through the connecting pipe 15, and then are discharged to the ground through the discharge pipe 4, which is located in the forward direction of the pressing roller 3, thereby realizing the recycling of materials, reducing material waste, and saving more energy.

[0044] Reference Figure 1 and Figure 3 A pushing assembly 62 is also connected to the material holding box 5, and the pushing assembly 62 includes a pushing block 621 and a moving rod 622. The side of the pushing block 621 close to the ground is in contact with the side of the filter screen 613 away from the ground. A sliding groove 53 is opened on the inner wall of the material holding box 5 along the width direction. One end of the pushing block is inserted into the sliding groove 53 and slides in the sliding groove 53. The end of the moving rod 622 close to the ground is welded and fixed to the pushing block 621. The moving rod 622 is vertically arranged, and the end of the moving rod 622 away from the ground extends out of the material holding box 5, and the moving rod 622 is slidably connected to the material holding box 5.

[0045] When the abutment plate 612 scrapes the material on the side wall of the pressing roller 3 into the material containing box 5, the material accumulates on the filter screen 613, and the pushing block moves along the filter screen 613 driven by the moving rod 622, so that the pushing block 621 is close to the side of the connecting pipe 15 and abuts against the material on the filter screen 613, and drives the material to move on the filter screen 613 toward the connecting pipe 15. The inner wall of the sliding groove 53 abuts against the side wall of the pushing block 621, guiding the pushing block 621, so that when the moving rod 622 drives the pushing block 621 to move, the pushing block 621 always abuts against the filter screen 613, so that the material on the filter screen 613 can enter the connecting pipe 15 through the discharge port 52, so that it is not easy for too much material to accumulate on the filter screen 613, and overflow from the material box 5 through the feed port 51, thereby reducing the possibility of material falling onto the paved runway, eliminating the need to clean the paved runway, reducing the construction steps, and thus improving the construction efficiency of runway paving.

[0046] Reference Figure 4 and Figure 5 The material holding box 5 is provided with an adjusting mechanism 7 for controlling the opening and closing of the feed port 51 and the discharge port 52. The adjusting mechanism 7 includes a driving assembly 71. The driving assembly 71 includes a rotating gear 711 and two movable plates 712. The rotating gear 711 is rotatably connected to the material holding box 5. The rotating gear 711 is meshed with two rotating racks 8. The rotating racks 8 are slidably connected to the material holding box 5. The two rotating racks 8 are parallel to each other. The rotating racks 8 correspond to the movable plates 712 one by one. The movable plates 712 are welded and fixed to one end of the rotating racks 8 away from the rotating gear 711. The two movable plates 712 are symmetrical with respect to the vertical line passing through the center of the rotating gear 711. The movable plates 712 are also slidably connected to the material holding box 5. A movable hole 7120 is opened on the movable plate 712 along the height direction of the movable plate 712. The end of the movable hole 7120 close to the ground is inclined in the direction away from the rotating gear 711.

[0047] Reference Figure 3 and Figure 5 The adjustment mechanism 7 also includes an adjustment component 72, which includes two baffles 721. The two baffles 721 are symmetrical with respect to the central axis of the material box 5, one of which is used to block the feed port 51, and the other baffle 721 is used to block the discharge port 52. A guide groove 54 is provided in the vertical direction on the side of the feed port 51 close to the ground, and a guide groove 54 is also provided on the side of the feed port 51 away from the ground. A guide groove 54 is provided on the side of the discharge port 52 close to the ground, and a guide groove 54 is also provided on the side of the discharge port 52 away from the ground. A mounting block 7211 is welded and fixed on the side of the baffle 721 close to the rotating rack 8. The mounting block 7211 is inserted into the moving hole 7120 and slides in the moving hole 7120 to drive the baffle 721 to slide in the guide groove 54.

[0048] When the materials on the pressing roller 3 are scraped into the material holding box 5 by the abutment plate 612, the rotating gear 711 is rotated so that the two rotating racks 8 drive the moving plate 712 to move away from the center of the rotating gear 711 at the same time, and the inner wall of the moving hole 7120 abuts against the side wall of the mounting block 7211, guiding the mounting block 7211, so that the baffle 721 moves along the trajectory of the moving hole 7120. The inner wall of the guide groove 54 abuts against the side wall of the baffle 721, which limits the baffle 721, so that the baffle 721 can only move in the vertical direction, so that the baffle 721 finally moves in the guide groove 54 in the direction away from the ground until one of the baffles 721 blocks the feed port 51 and the other baffle 721 blocks the discharge port 52, so that the mobile body 1 is prone to vibration during movement, and the material in the material box 5 will not fall out of the material box 5 through the feed port 51 under vibration, but fall onto the paved runway, so there is no need to clean the paved runway, which reduces the construction steps and improves the construction efficiency of runway paving.

[0049] Reference Figure 4 and Figure 5 The rotating rod 11 is provided with a rotating mechanism 12, and the rotating mechanism 12 includes an extrusion assembly 121, and the extrusion assembly 121 includes an extrusion rod 1211, a return spring 1212 and a push rod 1213. A rotating hole 1101 is penetrated at one end of the rotating rod 11, and the extrusion rod 1211 is adapted to be inserted in the rotating hole 1101 and slide in the rotating hole 1101. The extrusion rod 1211 is coaxial with the rotating rod 11, and one end of the return spring 1212 is welded and fixed to the rotating rod 11, and the other end is welded and fixed to the extrusion rod 1211. The pushing rod 1213 is inserted into the rotating hole 1101 and is slidably connected to the rotating rod 11. A fixing block 12131 is integrally formed on the side wall of the pushing rod 1213. A fixing hole 1102 is opened at one end of the rotating rod 11 along the length direction of the pressing roller 3. The fixing hole 1102 is connected to the moving hole 7120. An extrusion spring 131 is welded and fixed to the mobile body 1. An extrusion plate 13 is welded and fixed to the end of the extrusion spring 131 away from the mobile body 1. The extrusion plate 13 is located at the end of the extrusion rod 1211 away from the pushing rod 1213.

[0050] Reference Figure 4 and Figure 5 The rotating mechanism 12 also includes a rotating assembly 122, which includes a rotating block 1221 and a rotating rod 1222. The rotating block 1221 is welded and fixed to the side wall of the extrusion plate 13, and the rotating rod 1222 is rotatably connected to the mobile body 1. A rotating groove 12220 is opened on the side wall of the rotating rod 1222 in the circumferential direction. The rotating block 1221 is inserted into the rotating groove 12220 and moves in the rotating groove 12220 to drive the rotating rod 1222 to rotate.

[0051] When the pressing roller 3 moves to the feed port 51, the pushing rod 1213 is pressed toward the extrusion plate 13 until the pushing rod 1213 abuts against the extrusion rod 1211, and the return spring 1212 is compressed to drive the extrusion rod 1211 to move toward the extrusion plate 13 until the extrusion rod 1211 abuts against the extrusion plate 13. The pushing rod 1213 continues to move, compressing the extrusion spring 131, so that the extrusion rod 1211 drives the extrusion plate 13 to move, that is, the rotating block 1221 moves along the direction of the central axis of the rotating rod 1222, and the inner wall of the rotating groove 12220 abuts against the inner wall of the rotating block 1221, guiding the rotating block 1221, so that the rotating block 1221 moves along the trajectory of the rotating groove 12220, so that the rotating rod 1222 rotates around the central axis of the rotating rod 1222, thereby driving the rotating gear 711 to rotate, so that the two rotating racks 8 simultaneously drive the moving plate 712 to move in the direction close to the rotating gear 711, thereby causing the two baffles 721 to move in the direction close to the ground, thereby realizing the opening of the feed port 51 and the discharge port 52, and the abutment plate 612 abuts against the side wall of the pressing roller 3 under the action of the torsion spring 611. Then, the push rod 1213 is rotated, and the inner wall of the fixing hole 1102 abuts against the side wall of the fixing block 12131, which plays a limiting role, so that the pressing roller 3 rotates along with the rotation of the push rod 1213, so that the abutment plate 612 abuts and slides on the side wall of the pressing roller 3, facilitating the entry of materials.

[0052] When the materials on the side wall of the pressure roller have been scraped into the material holding box 5, the force of the extrusion push rod 1213 is removed, and the reset spring 1212 recovers its deformation, so that the extrusion rod 1211 moves away from the extrusion plate 13, and the extrusion plate 13 loses the extrusion force. The extrusion spring 131 recovers its deformation, so that the extrusion plate 13 is reset, that is, the extrusion plate 13 is pushed toward the direction close to the pressure roller 3, so that the rotating block 1221 moves along the direction of the central axis of the rotating rod 1222 toward the pressure roller 3, so that the rotating rod 1222 drives the rotating gear 711 to reverse, so that the rotating rack 8 drives the baffle 721 to move away from the ground, so that the feed port 51 and the discharge port 52 can be closed, so that the material in the material holding box 5 will not fall out of the material holding box 5.

[0053] Reference Figure 2 and Figure 3 A water tank 9 is welded and fixed on the mobile body 1, and a water inlet pipe 91 and a water outlet pipe 92 are connected to the bottom of the material box 5. The water inlet pipe 91 and the water outlet pipe 92 are respectively connected to the water tank 9. The water inlet pipe 91 is provided with a water inlet pump 911, and the water outlet pipe 92 is provided with a water outlet pump 921.

[0054] When the materials on the pressing roller 3 are scraped into the material box 5 by the abutment plate 612, the force of the extrusion push rod 1213 is removed, and under the action of the extrusion spring 131, the extrusion plate 13 drives the rotating block 1221 to move, thereby causing the baffle 721 to move away from the ground, so that the feed port 51 and the discharge port 52 are both in a closed state. Then, the water inlet pump 911 is started, so that the water in the water tank 9 enters the material holding box 5 through the water inlet pipe 91, so that the material in the material holding box 5 is immersed in the water, and the water inlet pump 911 is turned off, and then the moving rod 622 is moved to move the pushing block 621, and the pushing block 621 finally stops moving at the end of the filter screen 613 close to the feed inlet 51. During the movement, the pushing block 621 moves the water in the material holding box 5, so that the water in the material holding box 5 generates a water flow, and the material in the material holding box 5 is dispersed under the action of the water flow, so that the material is not easy to stick to the filter screen 613 and the inner wall of the material holding box 5, and at the same time, the material will not accumulate on the filter screen 613, which is convenient for the pushing block 621 to push the material on the filter screen 613;

[0055] Then, the water outlet pump 921 is started to recycle the water in the material holding box 5 into the water holding box 9 through the water outlet pipe 92. The suction force of the water outlet pump 921 also drives the materials to move in a concentrated direction close to the filter screen 613, so that the materials are not easy to adhere to the inner wall of the material holding box 5. The filter screen 613 plays a blocking role, so that the materials in the material holding box 5 will only exist on the side of the filter screen 613 away from the ground. When the water level in the material holding box 5 is lower than the filter screen 613, the materials settle on the filter screen 613. At this time, the materials are not easy to accumulate on one part of the filter screen 613, and the push rod 1213 is moved in a direction close to the extrusion plate 13, and the extrusion spring 131 is compressed, so that the extrusion plate 13 drives the rotating block 1221 to move, thereby moving the baffle 721 in a direction close to the ground, so that the feed port 51 and the discharge port 52 are in an open state. Then, the moving rod 622 is moved, so that the pushing block 621 pushes the material on the filter screen 613 to move toward the connecting pipe 15, so that the material on the filter screen 613 enters the discharge pipe 4 through the connecting pipe 15, and is then discharged to the ground in the forward direction of the pressing roller 3 through the discharge pipe 4. When water flows into the material holding box 5, the material in the material holding box 5 is also cleaned, so that the material that finally enters the discharge pipe 4 for recycling is not easily mixed with foreign objects, thereby improving the quality of the runway construction.

[0056] The implementation principle of a paving device for composite polyurethane runway surface construction in an embodiment of the present application is as follows: when the mobile body 1 moves forward, the material falls from the storage box 2 to the ground through the discharge pipe 4, and then the pressure roller 3 moves to the material on the ground and pushes and rolls the material so that the height of the rolled material from the ground is constant and the side of the rolled material away from the ground is on the same horizontal plane, that is, the material is evenly spread on the ground, thereby realizing the paving of the runway.

[0057] After paving is completed, start the lifting drive 10, so that the mounting frame 14 drives the pressure roller 3 to move to the feed port 51, squeezes the push rod 1213 in the direction close to the extrusion plate 13, and uses the extrusion rod 1211 to press the extrusion plate 13, so that the rotating block 1221 moves along the direction of the central axis of the rotating rod 1222, so that the rotating rod 1222 rotates around the central axis of the rotating rod 1222, driving the rotating gear 711 to rotate, so that the two rotating racks 8 simultaneously drive the moving plate 712 to move in the direction close to the rotating gear 711, so that the two baffles 721 move in the direction close to the ground, and the feed port 51 and the discharge port 52 can be opened. Under the action of the torsion spring 611, the abutment plate 612 extends out of the feed port 51 and abuts against the side wall of the press roller 3. Then the push rod 1213 is rotated to rotate the press roller 3, so that the side of the abutment plate 612 away from the torsion spring 611 abuts and slides on the side wall of the press tube, thereby scraping the material on the press roller 3 into the material box 5 and accumulating it on the filter screen 613.

[0058] Then the force of the extrusion push rod 1213 is removed, and the reset spring 1212 restores its deformation, causing the extrusion rod 1211 to move away from the extrusion plate 13. The extrusion plate 13 loses the extrusion force, and under the action of the extrusion spring 131, the rotating block 1221 is driven toward the direction close to the pressing roller 3, so that the rotating rod 1222 drives the rotating gear 711 to reverse, and the rotating rack 8 drives the baffle 721 to move away from the ground, thereby realizing the closure of the feed port 51 and the discharge port 52. The water in the water tank 9 is passed through the material holding box 5 by the water inlet pump 911, so that the material in the material holding box 5 is immersed in the water. The water inlet pump 911 is turned off, and then the moving rod 622 is moved to move the pushing block 621. The pushing block 621 finally stops moving at the end of the filter screen 613 close to the feed inlet 51. The pushing block 621 moves the water in the material holding box 5 during the movement, so that the water in the material holding box 5 generates a water flow. Under the action of the water flow, the material in the material holding box 5 is dispersed, so that the material is not easy to stick to the filter screen 613 and the inner wall of the material holding box 5, and the material will not accumulate on the filter screen 613.

[0059] Then, the water outlet pump 921 is started to recycle the water in the material storage box 5 into the water storage box 9 through the water outlet pipe 92, and the material settles on the filter screen 613. At this time, the material is not easy to accumulate on one part of the filter screen 613, and the push rod 1213 is moved in the direction close to the extrusion plate 13, and the extrusion spring 131 is compressed, so that the extrusion plate 13 drives the rotating block 1221 to move, so that the baffle 721 moves in the direction close to the ground, so that the feed port 51 and the discharge port 52 are in an open state. Then, the moving rod 622 is moved, so that the push block 621 pushes the material on the filter screen 613 to move in the direction close to the connecting pipe 15, so that the material on the filter screen 613 enters the discharge pipe 4 through the connecting pipe 15, and then is discharged to the ground in the forward direction of the nip roller 3 through the discharge pipe 4, so as to realize the recycling of materials, reduce the waste of materials, and save more energy.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
