Description

Technical Field

[0001] This application relates to the field of plastic running track construction, and in particular to an automatic construction machine for sports running track surface adhesive. Background Technology

[0002] The construction of a plastic running track involves mixing components A and B, adding a catalyst during the mixing process to form a viscous compound. This viscous compound is then placed in a drum mixer and mixed evenly with black rubber granules. The mixture is then transported to the site by a material truck. A paver first lays the viscous compound on the ground, and then anti-slip granules are sprayed onto the compound. The mixture is left to cure at room temperature, and finally, measurements are taken and lines are drawn to complete the construction of the plastic running track.

[0003] In related technologies, an automatic construction machine and method for polyurethane rubber plastic running track surface adhesive for sports fields are disclosed. The machine includes a surface adhesive mixing tank, a mobile vehicle fixedly mounted at the bottom of the mixing tank, and a drive motor fixedly mounted at the top. Inside the mixing tank, there is a mixing and pressing mechanism, and at the bottom right side, there is a discharge mechanism. The drive motor drives a reciprocating screw in the mixing and pressing mechanism to rotate, which in turn causes a connecting plate and a first spring to drive multiple longitudinal mixing rods in the mixing and pressing mechanism to mix the surface adhesive raw material. The reciprocating screw drives multiple longitudinal mixing rods and multiple transverse mixing rods to achieve longitudinal and transverse mixing of the surface adhesive raw material. The material is discharged entirely through the discharge port. However, there is no filtration process during discharge, which can easily lead to clumping at the corners of the drum, which is discharged along with the adhesive material.

[0004] The aforementioned technologies have the following defects: during discharge, some adhesive is discharged before it is fully mixed or during the discharge process, resulting in adhesive sticking and clumping, which affects the construction quality of the runway and therefore needs to be improved. Summary of the Invention

[0005] To address the issues of incomplete mixing or clumping of the discharged adhesive, this application provides an automatic application machine for sports track adhesive.

[0006] The automatic application machine for applying sports track surface adhesive provided in this application adopts the following technical solution:

[0007] An automatic construction machine for sports track surface adhesive, used to lay running tracks on the ground, includes a mixing drum and a mixing device. The mixing device is located inside the mixing drum and is rotatably connected to the mixing drum. A moving vehicle is fixedly connected to the mixing drum. A discharge port is provided at the bottom of the mixing drum. An adjustment device for controlling the opening and closing of the discharge port is provided on the mixing drum. A screening device is provided on the moving vehicle, which is aligned with the discharge port and located between the mixing drum and the ground. The screening device includes a screening component and a swing component. The screening component is connected to the moving vehicle, and the swing component is connected to the mixing drum. When the swing component moves, it drives the screening component to move along the length direction of the moving vehicle.

[0008] By adopting the above technical solution, the adhesive raw material is added into the mixing drum, and the mixing device is started to stir the adhesive in the mixing drum, turning the raw material into finished adhesive. Then, the discharge port is opened using an adjusting device, allowing the finished adhesive in the mixing drum to fall from the discharge port onto the screening component. The adjusting device is then moved to close the discharge port, ensuring that the screening component does not accumulate more adhesive than its capacity, preventing adhesive from overflowing onto the ground. Next, a swinging component drives the screening component to shake, discharging the stirred adhesive through the screening component, while any clumps or incompletely stirred adhesive remain on the screening component, ensuring the quality of the discharged adhesive and thus improving the quality of runway construction.

[0009] Optionally, the screening assembly includes a screening hopper and a screening screen. The screening hopper is placed below the discharge port, and the screening screen is placed inside the screening hopper. The screening screen is mounted on the mobile vehicle body (3) via a connecting block, and the screening screen is aligned with the discharge port.

[0010] By adopting the above technical solution, when the adhesive in the mixing drum falls onto the screening screen through the discharge port, the screening hopper prevents the adhesive from overflowing onto the ground. The mixed adhesive flows to the ground through the pores of the screening screen. However, any clumps or incompletely mixed adhesive remain on the screening screen due to the obstruction of the pores, preventing them from being discharged. This ensures that only fully mixed adhesive is discharged, thereby improving the quality of runway construction.

[0011] Optionally, the oscillating assembly includes an oscillating rack, an oscillating rod, and a propulsion spring. The oscillating rack is slidably connected to the bottom wall of the mixing drum. The oscillating rack abuts against the end of the oscillating rod away from the ground. The oscillating rod is rotatably connected to the moving vehicle body via a torsion spring. The end of the mixing rod near the ground abuts against the side wall of the screening screen. One end of the propulsion spring is fixedly connected to a connecting block, and the other end is fixedly connected to the screening screen, for pushing the screening screen towards the oscillating rod.

[0012] By adopting the above technical solution, after the adhesive in the mixing drum falls onto the screening screen through the discharge port, the mixed adhesive, under the action of gravity, permeates through the pores of the screening screen. Then, the swing rack is moved so that the sidewall of the upper teeth of the swing rack abuts against the end of the swing rod away from the screening screen, causing the swing rod to rotate around the torsion spring. This causes the swing rod to press the screening screen closer to the connecting block, compressing the propulsion spring. As the swing rack continues to move, the end of the swing rod away from the screening screen moves along the trajectory of the upper teeth of the swing rack until it reaches between two adjacent teeth, i.e., the swing rod separates from the sidewall of the upper teeth of the swing rack. This causes the swing rod to lose its pushing force, the torsion spring to return to its original deformation, and the end of the swing rod closer to the screening screen moves away from the connecting block around the torsion spring axis. At this point, the push spring also loses its compressive force and returns to its original deformation, pushing the sieve screen closer to the swing rod. This causes the sieve screen to move back and forth in the horizontal direction, making the adhesive sway on the sieve screen and dispersing the fabric. This makes it easier for the mixed adhesive to seep out through the pores of the sieve screen, preventing it from accumulating on the screen and increasing the rate at which the mixed adhesive seeps out through the sieve screen. This makes the operation convenient.

[0013] Optionally, the adjusting device includes an adjusting element and an adjusting assembly, both of which are connected to the stirring drum. The adjusting element rotates, driving the adjusting assembly to move, thereby controlling the opening and closing of the discharge port.

[0014] By adopting the above technical solution, when it is necessary to discharge the adhesive, rotating the adjusting component causes the adjusting assembly to move on the bottom wall of the mixing drum, so that the adjusting assembly and the discharge port continuously move from separation to overlap, thereby continuously opening the discharge port. This ensures that the adhesive falling onto the screening screen through the discharge port will not exceed the capacity of the screening screen, that is, the adhesive on the screening screen will not overflow from the side wall of the screening screen to the ground, avoiding waste of adhesive, making operation convenient and more energy-efficient.

[0015] Optionally, the adjusting assembly includes an adjusting rod, a rotating rack, and a sealing plate for blocking the discharge port. The adjusting rod is vertically arranged and rotatably connected to the moving vehicle body. A rotating gear is coaxially fixed to the adjusting rod. The rotating rack meshes with the rotating gear and is slidably connected to the bottom wall of the mixing drum. One end of the rotating rack is fixedly connected to the sealing plate, and the swing rack is fixedly connected to the side of the rotating rack near the ground.

[0016] By adopting the above technical solution, during construction, the adhesive needs to be discharged. Rotating the adjusting component causes the adjusting rod to rotate, which in turn drives the rotating gear. This causes the rotating rack to move the sealing plate closer to the adjusting rod, until the sealing plate overlaps with the discharge port until it is completely separated from the discharge port. At this point, the discharge port is open, and the adhesive in the mixing drum moves through the discharge port onto the screening screen under gravity. The adjusting component continues to rotate, causing the adjusting rod to drive the rotating gear in reverse, which in turn causes the rotating rack to move the sealing plate away from the adjusting rod until the sealing plate overlaps with the discharge port, thus sealing the discharge port and achieving convenient opening and closing of the discharge port.

[0017] Optionally, the adjusting component includes a rotation drive, an adjusting conveyor belt, and an abutment block. The adjusting conveyor belt is vertically arranged and rotatably connected to the stirring drum. The rotation drive is fixedly mounted on the mobile vehicle body. The output end of the rotation drive is coaxially fixed with the drive wheel of the adjusting conveyor belt to drive the adjusting conveyor belt to rotate. The abutment block is fixedly connected to the side wall of the adjusting conveyor belt. The side wall of the adjusting rod is provided with an adjusting groove along the circumference of the adjusting rod. One end of the abutment block is inserted into the adjusting groove and slides in the adjusting groove to drive the adjusting rod to rotate.

[0018] By adopting the above technical solution, when the adhesive needs to be discharged, the rotating drive is activated, causing the adjusting conveyor belt to rotate. When the end of the abutment block furthest from the mixing drum is inserted into the adjusting groove through one end opening, the adjusting conveyor belt drives the abutment block to move vertically. The inner wall of the adjusting groove abuts against the side wall of the abutment block, guiding the abutment block to move along the trajectory of the adjusting groove. This causes the adjusting rod to rotate around its central axis, causing the rotating gear to rotate. This rotates the rotating rack, moving the sealing plate closer to the adjusting rod, gradually separating the sealing plate from the discharge port. This allows the adhesive in the mixing drum to move through the discharge port onto the screening screen. When the abutment block reaches the center of the adjusting rod, it continues to move, causing the rotating gear to reverse. This causes the rotating rack to move the sealing plate away from the adjusting rod until the sealing plate overlaps with the discharge port, blocking the discharge port. At this point, the abutment block slides out from the other end of the adjusting groove, realizing the opening and closing of the discharge port. The operation is convenient.

[0019] Optionally, the mixing drum is provided with a scraping assembly, which includes a scraping ring, a magnet, and an iron sheet for engaging with the magnet. The scraping ring is fixedly connected to the magnet on the side away from the central axis of the mixing drum, and the magnet abuts against the inner wall of the mixing drum on the side away from the central axis of the mixing drum. The abutting block is fixedly connected to the iron sheet on the end away from the adjusting rod, and the iron sheet abuts against the outer wall of the mixing drum on the side away from the abutting block.

[0020] By adopting the above technical solution, after the abutment block slides out from one end of the adjusting groove, it moves to the other side of the adjusting conveyor belt and continues to move vertically. At this time, the abutment block drives the iron sheet to adhere to the outer wall of the mixing drum. When the iron sheet moves to the magnet, it is attracted to the magnet, and the adjusting conveyor belt continues to drive the abutment block to move. Under the action of the iron sheet and the magnet, the scraping ring moves with the movement of the abutment block. That is, the scraping ring moves along the height of the mixing drum on the inner wall of the mixing drum, thereby scraping off the adhesive on the inner wall of the mixing drum. This ensures that the scraping ring moves up and down once after each movement of the sealing plate. This reduces the possibility of the adhesive sticking to the inner wall of the mixing drum for a long time and not being usable, thus avoiding the waste of adhesive, saving energy, and ensuring that all the adhesive in the mixing drum is mixed, improving the quality of adhesive mixing and forming, improving the quality of adhesive discharge, and thus improving the quality of runway construction.

[0021] Optionally, the mixing drum has a feed inlet connected to its side wall, and the screening screen is connected to a tilting device. The tilting device includes a driving component and a tilting component. Both the driving component and the tilting component are connected to the moving vehicle. When the driving component moves, it drives the screening screen to move on the tilting component, thereby driving the screening screen to tilt.

[0022] By adopting the above technical solution, the adhesive discharged from the outlet is sieved through a screening screen. Adhesive that is not fully mixed or sticks together remains on the screen. Then, a drive assembly moves the screen away from the ground. When the screen reaches the tilting assembly, the tilting assembly guides the screen, causing it to rotate around the central axis of the connecting block. This aligns the side of the screen containing the adhesive with the inlet. Under gravity, the adhesive on the screen enters the mixing drum through the inlet for further mixing. This repeated mixing improves the quality of the adhesive, thus improving the quality of the adhesive discharged from the mixing drum.

[0023] Optionally, the drive assembly includes a moving drive component and a rotating block. The moving drive component is fixedly mounted on the moving vehicle body. The rotating block is rotatably connected to the output end of the moving drive component. A connecting block passes through the rotating block and is rotatably connected to it. A guide surface is provided on the side wall of the connecting block. Guide rods are provided on the outer wall of the stirring drum and on the moving vehicle body. When the guide rods abut against the guide surface, the rotating block rotates about the central axis of the rotating block.

[0024] By adopting the above technical solution, the adhesive discharged from the outlet is screened by a screening screen. Adhesive that is not fully mixed or sticks together remains on the screen. The moving drive is then activated, causing the screening screen to move away from the ground. When the guide surface of the connecting block away from the ground abuts against the guide rod, the guide surface acts as a guide, causing the rotating block to drive the connecting block to rotate around its central axis. This moves the screening screen out of the vertical area of ​​the mixing drum, facilitating its movement away from the ground. When the screening screen reaches the tilting component, the tilting component causes the screen to rotate, allowing the remaining adhesive on the screen to be poured into the mixing drum through the inlet. Then, the moving drive moves the screening screen closer to the ground, separating it from the tilting component, and the screen returns to a horizontal position. When the guide surface of the connecting block near the ground abuts against the guide rod, the rotating block rotates around its central axis, causing the screening screen to move to the area below the mixing drum, i.e., the screening screen is aligned with the discharge port. This allows any unmixed or clump-forming adhesive on the screening screen to be poured into the mixing drum for further mixing, thus improving the quality of the finished adhesive at the mixing point.

[0025] Optionally, the flipping assembly includes a flipping plate, which is fixedly connected to the mixing drum and located at the feed inlet. The flipping plate is provided with a flipping hole for inserting a connecting block. When the connecting block is inserted into the flipping hole and slides within the flipping hole, it drives the screening screen to rotate around the central axis of the connecting block.

[0026] By adopting the above technical solution, when the moving drive unit moves the screening screen to the tilting plate, the connecting block is inserted into the tilting hole from the end of the tilting hole closest to the ground. The inner wall of the tilting hole abuts against the side wall of the connecting block, which guides the connecting block and causes it to move along the trajectory of the tilting hole. This allows the connecting block to rotate around its central axis, so that the side of the screening screen containing the adhesive is aligned with the feed inlet. Under the action of gravity, the adhesive on the screening screen enters the mixing drum through the feed inlet for another stirring. The multiple stirrings improve the quality of the adhesive stirring, thereby improving the quality of the adhesive discharged from the mixing drum, and thus improving the quality of the runway construction.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. Add the raw adhesive material to the mixing drum and start the mixing device to mix the adhesive material in the drum, turning the raw material into finished adhesive material. Then, use the adjusting device to open the discharge port, allowing the finished adhesive material in the mixing drum to fall onto the screening component. Next, move the adjusting device to close the discharge port, ensuring that the screening component does not exceed its capacity and prevents adhesive from overflowing onto the ground. Then, use the oscillating component to shake the screening component, discharging the mixed adhesive material through it. Adhesive that has clumped or not fully mixed remains on the screening component, ensuring the quality of the discharged adhesive and thus improving the quality of the runway construction.

[0029] 2. When the adhesive in the mixing drum falls onto the screening screen through the discharge port, the screening hopper prevents the adhesive from overflowing onto the ground. The fully mixed adhesive flows to the ground through the mesh of the screening screen, while any clumps or incompletely mixed adhesive remain on the screen due to the obstruction of the mesh. This ensures that only fully mixed adhesive is discharged, thus improving the quality of the runway construction. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses an automatic construction machine for sports track surface adhesive, used for laying running tracks on the ground. (See also...) Figure 1 and Figure 2 The automatic construction machine for sports track surface adhesive includes a mixing drum 1 and a mixing device 2. The mixing device 2 is located inside the mixing drum 1 and is rotatably connected to the mixing drum 1. The mixing device 2 includes several mixing blades for mixing and dispersing the surface adhesive inside the mixing drum 1. A mobile vehicle body 3 is welded and fixed to the mixing drum 1. A feed inlet 11 is connected to the side wall of the mixing drum 1, and a discharge outlet 10 is opened through the bottom of the mixing drum 1. A screening device 5 is installed on the mobile vehicle body 3. The screening device 5 is located on the side of the discharge outlet 10 away from the mixing drum 1. The screening device 5 includes a screening assembly 51, which includes a screening hopper 512 and a screening screen 511. The screening hopper 512 is located below the discharge outlet 10, and the screening screen 511 is located inside the screening hopper 512. The peripheral side wall of the screening screen 511 is welded and fixed to the screening hopper 512. The screening screen 511 is placed horizontally and aligned with the discharge outlet 10. A screening screen 511 is located between the mixing drum 1 and the ground. A connecting block 6 is slidably connected to one side of the screening screen 511. A moving drive component 911 is fixedly installed on the moving vehicle body 3 by bolts. In this embodiment, the moving drive component 911 is a telescopic cylinder. The connecting block 6 is connected to the output end of the moving drive component 911. The moving drive component 911 drives the connecting block 6 to move towards or away from the ground.

[0038] The raw material for the adhesive is fed into the mixing drum 1 through the inlet 11. The mixing blades rotate inside the mixing drum 1, mixing and breaking down the adhesive, thus transforming the raw material into the finished adhesive. When track construction is required, the adhesive in the mixing drum 1 falls onto the screening screen 511 through the outlet 10. The screening hopper 512 acts as a barrier, preventing the adhesive on the screening screen 511 from leaking onto the ground through its edges. The mixed adhesive flows to the ground through the pores of the screening screen 511, while any clumps or incompletely mixed adhesive remain on the screening screen 511 due to the barrier effect. This ensures that only fully mixed adhesive is discharged, thereby improving the quality of track construction.

[0039] Reference Figure 2 and Figure 3 The screening device 5 also includes a swing assembly 52, which includes a swing rack 521, a swing rod 522, and a propulsion spring 523. The swing rack 521 is slidably connected to the bottom wall of the mixing drum 1. The swing rod 522 is vertically arranged, and the swing rack 521 abuts against the end of the swing rod 522 away from the ground. A torsion spring 12 is welded and fixed to the center of the swing rod 522. A rotating shaft passes through the torsion spring 12 and is welded and fixed to the moving vehicle body 3. The end of the torsion spring 12 away from the swing rod 522 is welded and fixed to the moving vehicle body 3. The end of the mixing rod near the ground abuts against the side of the screening screen 511 away from the connecting block 6. The connecting block 6 includes a mounting block 63. A mounting hole 630 is opened on the side of the mounting block 63 near the screening screen 511. A mounting rod 5111 is welded and fixed to the side wall of the screening screen 511 and is inserted into the mounting hole 630. One end of the push spring 523 is welded and fixed to the inner wall of the mounting hole 630 away from the screen 511, and the other end is welded and fixed to the end of the mounting rod 5111 away from the screen 511.

[0040] When the adhesive in the mixing drum 1 falls onto the screening screen 511 through the discharge port 10, the mixed adhesive, under the action of gravity, permeates through the pores of the screening screen 511. Then, the swing rack 521 is moved so that the side wall of the upper teeth of the swing rack 521 abuts against the end of the swing rod 522 away from the screening screen 511, and drives the swing rod 522 to rotate around the pivot, so that the swing rod 522 squeezes the screening screen 511 towards the connecting block 6, compressing the push spring 523. As the swing rack 521 continues to move, the end of the swing rod 522 away from the screening screen 511 moves along the trajectory of the upper teeth of the swing rack 521 until it moves between two adjacent teeth on the swing rack 521, that is, the swing rod 522 separates from the side wall of the upper teeth of the swing rack 521, so that the swing rod 522 loses its pushing force, the torsion spring 12 restores its deformation, and the end of the swing rod 522 close to the screening screen 511 moves away from the connecting block 6 with the torsion spring 12 as the axis. At this time, the push spring 523 also loses its squeezing force and restores its deformation, pushing the sieve 511 towards the swing rod 522, causing the sieve 511 to move back and forth in the horizontal direction. This causes the adhesive to shake on the sieve 511, dispersing the fabric on the sieve 511. Consequently, the mixed adhesive is more likely to seep out through the pores of the sieve 511 and is less likely to accumulate on the sieve 511, thus increasing the rate at which the mixed adhesive seeps out through the sieve 511.

[0041] Reference Figure 1 and Figure 4 The mixing drum 1 is equipped with an adjusting device 4 for controlling the opening and closing of the discharge port 10. The adjusting device 4 includes an adjusting component 411. The adjusting component 411 includes a rotation drive component 4111, an adjusting conveyor belt 4112, and an abutment block 4113. The adjusting conveyor belt 4112 is vertically arranged and rotatably connected to the mixing drum 1. The rotation drive component 4111 is fixedly mounted on the moving vehicle body 3 by bolts. In this embodiment, the rotation drive component 4111 is a motor or other power source capable of rotating the adjusting conveyor belt 4112. The output end of the rotation drive component 4111 is coaxially fixed with the drive wheel of the adjusting conveyor belt 4112 to drive the adjusting conveyor belt 4112 to rotate. The abutment block 4113 is welded and fixed to the side wall of the adjusting conveyor belt 4112. The adjustment device 4 also includes an adjustment assembly 41, which includes an adjustment rod 412. The adjustment rod 412 is vertically arranged and rotatably connected to the moving vehicle body 3. An adjustment groove 4120 is provided along the side wall of the adjustment rod 412. The two ends of the adjustment groove 4120 are connected to the two ends of the adjustment rod 412. One end of the abutment block 4113 is inserted into the adjustment groove 4120 and slides within the adjustment groove 4120 to drive the adjustment rod 412 to rotate.

[0042] Reference Figure 4 and Figure 5A rotating gear 8 is coaxially fixed to the end of the adjusting rod 412 near the ground, and the rotating gear 8 is also rotatably connected to the moving vehicle body 3. A rotating rack 413 is slidably connected to the bottom wall of the mixing drum 1. The rotating rack 413 meshes with the rotating gear 8. A sealing plate 414 is welded and fixed to the end of the rotating rack 413 away from the adjusting rod 412. The diameter of the sealing plate 414 is larger than the diameter of the discharge port 10. The swing rack 521 is welded and fixed to the side of the rotating rack 413 near the ground.

[0043] When it is necessary to discharge the adhesive, the rotating drive 4111 is activated, causing the adjusting conveyor belt 4112 to rotate. When the end of the abutment block 4113 away from the mixing drum 1 is inserted into the adjusting groove 4120 through one end opening, the adjusting conveyor belt 4112 drives the abutment block 4113 to move vertically. The inner wall of the adjusting groove 4120 abuts against the side wall of the abutment block 4113, guiding the abutment block 4113 to move along the trajectory of the adjusting groove 4120. This causes the adjusting rod 412 to rotate around its central axis, causing the rotating gear 8 to rotate. This drives the rotating rack 413 to move the sealing plate 414 closer to the adjusting rod 412, causing the sealing plate 414 to gradually separate from the discharge port 10. As a result, the adhesive in the mixing drum 1 moves through the discharge port 10 onto the screening screen 511 under the action of gravity. When the abutment block 4113 moves to the center of the adjusting rod 412, it continues to move. Because the rotation direction of the lower half of the adjusting groove 4120 is opposite to that of the upper half, the rotating gear 8 reverses direction. This causes the rotating rack 413 to drive the sealing plate 414 to move away from the adjusting rod 412 until the sealing plate 414 overlaps with the discharge port 10, thus blocking the discharge port 10. At this time, the abutment block 4113 slides out from the other end of the adjusting groove 4120 and moves to the other side of the adjusting conveyor belt 4112, realizing the opening and closing of the discharge port 10, which is convenient to operate.

[0044] Reference Figure 1 and Figure 4A scraping assembly 42 is connected to the mixing drum 1. The scraping assembly 42 includes a scraping ring 421, a magnet 4211, and an iron sheet 41131 for adhering to the magnet 4211. The scraping ring 421 is glued to the magnet 4211 on the side away from the central axis of the mixing drum 1. The magnet 4211 is in contact with the inner wall of the mixing drum 1 on the side away from the central axis of the mixing drum 1. The end of the abutment block 4113 away from the adjusting rod 412 is glued to the iron sheet 41131. When the side of the iron sheet 41131 away from the abutment block 4113 abuts against the outer wall of the stirring drum 1 and moves to the position of the magnet 4211, the attraction between the magnet 4211 and the iron sheet 41131 can satisfy the attraction between the magnet 4211 and the iron sheet 41131 across the thickness of the side wall of the stirring drum 1. The side of the magnet 4211 away from the scraping ring 421 is glued to the limiting block 14. A limiting groove 15 is opened on the inner wall of the stirring drum. The limiting groove 15 is set in the vertical direction. The limiting block 14 is adapted to be inserted into the limiting groove 15 and slides in the limiting groove 15. The inner wall of the limiting groove 15 abuts against the side wall of the limiting block 14, which limits the limiting block 14, so that the scraping ring 421 will not deflect horizontally. That is, the magnet 4211 is always in close contact with the inner wall of the stirring cylinder 1, so that the iron sheet 41131 and the magnet 4211 are not easily separated when they are attracted by the thickness of the stirring cylinder 1. There is always an attraction between the iron sheet 41131 and the magnet 4211, so that the scraping ring 421 will move with the movement of the abutment block 4113.

[0045] After the abutment block 4113 slides out from one end of the adjusting groove 4120, it moves to the other side of the adjusting conveyor belt 4112 and continues to move vertically. At this time, the abutment block 4113 drives the iron sheet 41131 to adhere to the outer wall of the mixing drum 1. When the iron sheet 41131 moves to the magnet 4211, it attracts the magnet 4211 through the thickness of the side wall of the mixing drum 1. The adjusting conveyor belt 4112 continues to drive the abutment block 4113 to move. Under the action of the iron sheet 41131 and the magnet 4211, the scraping ring 421 moves with the movement of the abutment block 4113. That is, the scraping ring 421 moves on the inner wall of the mixing drum 1 in the height direction of the mixing drum 1, thereby scraping off the adhesive on the inner wall of the mixing drum 1. This causes the scraping ring 421 to move up and down once after each movement of the sealing plate 414. This reduces the possibility of the adhesive sticking to the inner wall of the mixing drum 1 for a long time and not being usable, thus avoiding waste of adhesive, saving energy, and ensuring that all the adhesive in the mixing drum 1 is mixed, improving the quality of adhesive mixing and the quality of adhesive discharge, thereby improving the quality of track construction.

[0046] Reference Figure 1 and Figure 2The screening screen 511 is connected to a tilting device 9, which includes a drive assembly 91. The drive assembly 91 includes a rotating block 912, which is rotatably connected to the output end of the moving drive component 911. The connecting block 6 includes a connecting rod 62, which passes through the rotating block 912 and is rotatably connected to it. A rubber ring 621 is fitted on the side wall of the connecting rod 62, which is adapted to the rotating block 912 to increase the friction between the connecting rod 62 and the rotating block 912, making it difficult for the connecting rod 62 to rotate within the rotating block 912. The connecting block 6 also includes two guide blocks 61, both of which are welded and fixed to the connecting rod 62. One guide block 61 has a guide surface 610 cut on the side away from the ground, and the other guide block 61 has a guide surface 610 cut on the side closer to the ground. The two guide surfaces 610 are symmetrical about the central axis of the connecting rod 62. A guide rod 13 is welded and fixed to the outer wall of the mixing drum 1 and the moving vehicle body 3. The guide rod 13 is set vertically. When the guide rod 13 abuts against the guide surface 610, the rotating block 912 rotates about the central axis of the rotating block 912.

[0047] The adhesive discharged from the outlet 10 is sieved through the screening screen 511. Any adhesive that is not fully mixed or remains stuck on the screening screen 511. The moving drive component 911 is activated, causing the screening screen 511 to move away from the ground. When one of the guide blocks 61's guide surfaces 610, located away from the ground, abuts against the guide rod 13, the guide surface 610 acts as a guide, causing the rotating block 912 to drive the connecting rod 62 to rotate around its central axis. Under the action of the rubber ring 621, the connecting rod 62 is less likely to rotate within the rotating block 912 around its central axis, thus allowing the screening screen 511 to move out of the vertical area of ​​the mixing drum 1, facilitating its movement away from the ground. When the moving drive 911 drives the rotating block 912 to move closer to the ground, the guide surface 610 of the other guide block 61 on the side closer to the ground abuts against the guide rod 13, causing the rotating block 912 to rotate around the central axis of the rotating block 912, thereby moving the screening screen 511 to the area below the mixing drum 1, that is, the screening screen 511 is aligned with the discharge port 10, thus realizing the reset of the screening screen 511.

[0048] Reference Figure 1 and Figure 2The tilting device 9 also includes a tilting assembly 92, which includes a tilting plate 921. The tilting plate 921 is welded and fixed to the side wall of the mixing drum 1 and is located at the feed inlet 11. A tilting hole 9210 is provided through the tilting plate 921, and the end of the tilting hole 9210 near the ground is connected to the side of the tilting plate 921 near the ground. The connecting block 6 also includes a connecting rod 64, which is welded and fixed to the connecting rod 62. When the connecting rod 64 is inserted into the tilting hole 9210 and slides within the tilting hole 9210, it drives the screening screen 511 to rotate about the central axis of the connecting rod 62.

[0049] When the moving drive component 911 moves the screening screen 511 to the tilting plate 921, the connecting rod 64 is inserted into the tilting hole 9210 from the end near the ground. The inner wall of the tilting hole 9210 abuts against the side wall of the connecting rod 64, guiding the connecting rod 64 and causing it to move along the trajectory of the tilting hole 9210. This causes the rubber ring 621 to rub against the rotating block 912, thereby causing the screening screen 511 to rotate about the central axis of the connecting rod 62 until the side of the screening screen 511 containing the adhesive is aligned with the feed inlet 11. Under the action of gravity, the adhesive on the screening screen 511 enters the mixing drum 1 through the feed inlet 11 for another stirring. The repeated stirring improves the mixing quality of the adhesive, thereby improving the quality of the adhesive discharged from the mixing drum 1, and thus improving the quality of the track construction.

[0050] The implementation principle of the automatic construction machine for sports track surface adhesive in this application embodiment is as follows: The surface adhesive raw material is fed into the mixing drum 1 through the feed port 11. The mixing blades rotate in the mixing drum 1 to stir and disperse the surface adhesive, turning the raw material into the finished surface adhesive. When track construction is required, the surface adhesive in the mixing drum 1 falls onto the screening screen 511 through the discharge port 10. Under the action of gravity, the stirred surface adhesive permeates through the pores of the screening screen 511. Then, the swing rack 521 is moved so that the side wall of the upper teeth of the swing rack 521 abuts against the end of the swing rod 522 away from the screening screen 511, and drives the swing rod 522 to rotate around the pivot, so that the swing rod 522 squeezes the screening screen 511 towards the connecting block 6, compressing the push spring 523. As the swing rack 521 continues to move, the end of the swing rod 522 away from the screening screen 511 moves along the trajectory of the upper teeth of the swing rack 521 until it moves between two adjacent teeth on the swing rack 521, that is, the swing rod 522 separates from the side wall of the upper teeth of the swing rack 521, so that the swing rod 522 loses its pushing force, the torsion spring 12 restores its deformation, and the end of the swing rod 522 close to the screening screen 511 moves away from the connecting block 6 with the torsion spring 12 as the axis. At this time, the push spring 523 also loses its compressive force and restores its deformation, pushing the screening screen 511 towards the swing rod 522. This causes the screening screen 511 to move back and forth in the horizontal direction, making the adhesive on the screening screen 511 shake and disperse the fabric. This makes it easier for the mixed adhesive to seep out through the pores of the screening screen 511, preventing any sticky clumps or unmixed adhesive from being discharged through the screening screen 511. As a result, only mixed adhesive is discharged, thus improving the quality of the runway construction.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
