Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of road engineering, in particular to a construction device for filling a gap between an edge of an asphalt pavement and a curbstone and a construction method thereof. Background Art
[0002] During asphalt pavement construction, close contact between the pavement edge and the curb is required to prevent water seepage from the edge into the pavement structure. If the curb is constructed first, the roller can easily damage the curb or its contour during the pavement paving and rolling process. Alternatively, if the pavement is constructed first and then the curb is applied, the entire asphalt pavement must be poured before the edge is cut. However, pouring the entire pavement increases raw material loss and costs, and requires additional steps, hindering construction time. Therefore, a gap must be reserved between the edge of the asphalt pavement and the inside of the curb, and then the gap between the curb must be filled and rolled.
[0003] In the prior art, the gaps between curbstones need to be filled manually by workers using shovels and then compacted by rollers. Common filling devices cannot effectively and evenly fill the gaps deeply. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the present invention provides a construction device and a construction method for filling the gap between the edge of an asphalt pavement and a curb, which solves the problem of low efficiency in filling and rolling the gap between curbs.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a construction device for filling gaps between asphalt pavement edges and curbstones, comprising a carrier vehicle and:
[0006] The spreading barrel is arranged on one side of the carrier vehicle, and flat discharge ports are evenly arranged on the outer arc surface of the spreading barrel. The spreading barrel can rotate about its own center of circle so that different flat discharge ports can face the gap below. The flat discharge port facing below can be inserted into the gap and fill the lower layer of the gap. The rotation direction of the spreading barrel is the same as the rotation direction of the wheels of the carrier vehicle to compensate for the movement of the carrier vehicle.
[0007] The end of the flat discharge port away from the center of the spreading barrel is an open end. When the flat discharge port rotates, the side that is separated from the gap is the open side.
[0008] The side plate is arranged on the opening side and is rotatably mounted on the spreading barrel. The side plate can be opened through a transmission mechanism when the flat discharge port initially leaves the gap, so that the opening side can also discharge material to compensate for the rotation amount of the flat discharge port and make the opening side face the upper filler of the gap.
[0009] Furthermore, the transmission mechanism includes:
[0010] The first gear, the number of which is the same as the number of the flat discharge ports, is rotatably mounted on one side of the spreading barrel via a rotating shaft and corresponds one-to-one to the side plates;
[0011] A second connecting rod is fixed on the side of the first gear close to the spreading barrel, and one end of the second connecting rod is fixedly connected to the side plate through the first connecting rod;
[0012] A fixed plate is located on both sides of the spreading barrel. An inner gear ring and an outer gear ring are fixed on the fixed plate close to the first gear. The teeth of the inner gear ring are arranged on one side below the side plate, and the outer gear ring is arranged on the other side below the side plate. The first gear can engage with the inner gear ring and the outer gear ring respectively in stages.
[0013] Furthermore, the present invention further comprises a third connecting rod, the third connecting rod being fixedly mounted on one side of the first gear, a slider being fixed to one end of the third connecting rod, a sliding groove cooperating with the sliding groove being provided on the fixed plate, and the sliding groove being distributed in an area on the fixed plate that is staggered with the inner gear ring and the outer gear ring;
[0014] Ports are provided at both ends of the slide, and there is a free space between the two ports, and the free space does not limit the slider.
[0015] Furthermore, one end of the rotating shaft extends to the inside of the spreading barrel and is fixedly sleeved with a cam, and T-shaped hammers are fixedly connected to both sides of the cam, and the T-shaped hammers correspond to the positions of the flat discharge port.
[0016] Furthermore, a central axis is provided on both sides of the spreading barrel, and the central axis is rotatably connected to the fixed plate through bearings. A driving mechanism is provided on the side of the spreading barrel close to the carrier, and the driving mechanism includes a motor. The power output end of the motor is fixedly connected to a second gear, and the central axis close to the carrier passes through the fixed plate and is sleeved with a third gear, and the second gear is meshed with the third gear.
[0017] Furthermore, an inner cylinder is provided inside the spreading cylinder, and an inclined discharge port cooperating with the flat discharge port is opened at the lower part of the inner cylinder. A mounting shaft is fixed on one side of the inner cylinder, and a worm gear is provided after the mounting shaft passes through the middle shaft. A worm is meshedly connected to the worm gear, and a handle is provided at the lower end of the worm gear.
[0018] Furthermore, a connecting frame is fixed on the fixed plate, and the mounting shaft is rotatably connected to the connecting frame through a bearing. The worm gear, the second gear and the third gear are all located inside the connecting frame, and the worm is rotatably installed inside the connecting frame. The handle is located outside the connecting frame, and a cylinder is installed on the carrier, and the end of the cylinder piston rod is fixedly connected to the upper end of the connecting frame.
[0019] Furthermore, a feed hopper is provided on the carrier vehicle, a vibration motor is fixed to the outer wall of the feed hopper, and a connecting pipe is provided at the lower end of the feed hopper, and the other end of the connecting pipe is inserted into the interior of the central shaft and is rotatably connected thereto.
[0020] Furthermore, a first pressing roller and a second pressing roller cooperating with the spreading barrel are sequentially provided on one side of the carrier.
[0021] The present invention also provides a method for constructing a filler in the gap between an asphalt pavement edge and a curbstone, which is applicable to the above-mentioned asphalt pavement edge and curbstone filler construction device, and comprises the following steps:
[0022] Step 1: Align the flat discharge port with the curb gap, and use the cylinder to control the lowest flat discharge port to insert into the curb gap;
[0023] Step 2: Turn on the driving mechanism to make the spreading barrel start to rotate and push the carrier to move at the same time. The rotation direction of the spreading barrel is the same as the rotation direction of the wheels of the carrier to compensate for the movement of the carrier. When the spreading barrel rotates, the open end of the flat discharge port at the bottom faces the lower filler in the gap. When the flat discharge port initially leaves the gap, the side plate opens so that the opening side can also discharge material, so that the opening side faces the upper filler in the gap, and when the spreading barrel continues to rotate, the side plate closes and the flat discharge port no longer discharges material.
[0024] The present invention has the following beneficial effects:
[0025] 1. The device and method for filling the gap between the edge of the asphalt pavement and the curbstone, by arranging a spreading barrel, a flat discharge port and a side plate, enables different flat discharge ports to face the gap below, and the flat discharge port facing below can be inserted into the gap. First, the lower layer of the gap is filled. Since the rotation direction of the spreading barrel is the same as the rotation direction of the wheels of the carrier vehicle, the movement of the carrier vehicle can be compensated, so that the flat discharge port is always approximately in the same position of the corresponding gap, and the flat discharge port will gradually move upward with the rotation of the spreading barrel. Therefore, the gap can be filled in layers from bottom to top. During the discharge process of the flat discharge port, the side plate will open, so that the open side can also discharge material, so as to compensate for the rotation of the flat discharge port and reduce the influence of the side plate on the discharge.
[0026] 2. The device and method for filling the gap between the edge of the asphalt pavement and the curbstone, by setting a first gear, an inner gear ring and an outer gear ring, can control the opening and closing of the side panels during filling. At the same time, the rotation of the first gear drives the rotation of the T-shaped hammer to forcibly push the material out of the flat discharge port, thereby achieving mechanical arch breaking, reducing the occurrence of bridging during the discharge process, and ensuring smooth material discharge.
[0027] 3. The device and method for filling the gap between the edge of the asphalt pavement and the curbstone, by providing an inner cylinder and an inclined discharge port, allows the material inside the spreading cylinder to be discharged only through the flat discharge port at the bottom. The inner cylinder blocks the discharge of the flat discharge port in the non-filling area, preventing the centrifugal force of the rotating spreading cylinder from causing the material to be thrown out and spread everywhere, resulting in material waste.
[0028] 4. The device and method for constructing a filler in the gap between the edge of an asphalt pavement and a curbstone are provided with a worm gear and a worm. By rotating the worm gear, the worm gear can be driven to rotate at the beginning and end of the filling work, thereby adjusting the inner cylinder's inclined discharge port downward or upward to control discharge and non-discharge. The worm gear is an active component, and can only drive the worm gear, but cannot be reversely driven by the worm gear. The worm gear has self-locking properties and can fix the inner cylinder's inclined discharge port stably downward or upward.
[0029] 5. The device and method for filling the gap between the edge of the asphalt pavement and the curbstone and the method for filling the gap between the edge of the asphalt pavement and the curbstone are configured with a first pressing roller and a second pressing roller. After the gap at the edge of the curbstone is filled, the first pressing roller performs an initial precise compaction operation on the loose material in the gap at the edge of the curbstone, and then the second pressing roller rolls to perform a secondary compaction operation on the gap between the asphalt pavement and the curbstone, so that the pavement and the gap are highly consistent.
[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0048] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
[0049] The following is based on Figures 1-15The present invention provides a device and method for constructing a gap filler between an asphalt pavement edge and a curb.
[0050] On the one hand, an embodiment of the present invention provides a construction device for filling the gap between the edge of an asphalt pavement and a curb.
[0051] See also Figure 1-Figure 2 The device for filling the gap between the edge of the asphalt pavement and the curb includes a carrier 1, which can carry filling tools and has maneuverability. It only needs to be manually controlled in direction to provide a stable mobile platform for filling construction operations, greatly reducing time costs. A feed hopper 2 is provided on the carrier 1. The feed hopper 2 is a mechanism for conveying, temporarily storing and guiding materials (including asphalt, mineral powder, river sand, gravel and wood fiber) into subsequent processes. As the entrance for materials to enter, it receives and temporarily stores materials. The large capacity of the feed hopper 2 achieves stable feeding and reduces the frequency of manual operation. A vibration motor 11 is fixed to the outer wall of the feed hopper 2. The vibration motor 11 provides power for the feed hopper 2, so that the material moves evenly and continuously along the feed hopper 2 under the action of vibration, thereby realizing quantitative feeding and avoiding material blockage. A connecting pipe 10 is provided at the lower end of the feed hopper 2, and the other end of the connecting pipe 10 is inserted into the interior of the central axis 31 and is rotatably connected thereto. The connecting pipe 10 realizes material transmission between the feed hopper 2 and the spreading barrel 3.
[0052] See also Figures 1-10 A spreading barrel 3 and a side plate 42 are also provided.
[0053] The spreading barrel 3 is arranged on one side of the carrier 1, and the outer arc surface of the spreading barrel 3 is evenly provided with flat discharge ports 41. The spreading barrel 3 can rotate with its own center of circle. The rotation is mainly realized by the driving mechanism 7, so that different flat discharge ports 41 can face the gap below. The flat discharge port 41 facing below can be inserted into the gap and fill the lower layer of the gap. The end of the flat discharge port 41 away from the center of the spreading barrel 3 is the open end. When the flat discharge port 41 rotates, the side that is separated from the gap at the end is the open side (refer to Figure 10 , the carrier 1 moves to the left, the spreading barrel 3 rotates counterclockwise, and the opening side is the side that is separated from the gap after the flat discharge port 41).
[0054] The side plate 42 is arranged on the opening side and is rotatably mounted on the spreading barrel 3. The side plate 42 can be opened through the transmission mechanism when the flat discharge port 41 initially leaves the gap, so that the opening side can also discharge the material to compensate for the rotation amount of the flat discharge port 41 and make the opening side face the upper layer of filler in the gap.
[0055] The specific filling process is described below: Figure 10 In (A), the figure takes one of the flat discharge ports a as an example to describe the movement and change state of the flat discharge port 41. The rotation direction of the spreading barrel 3 should be the same as the rotation direction of the wheels of the vehicle 1 ( Figure 10The material spreading barrel 3 rotates counterclockwise from the perspective shown in the figure), and the wheels also rotate counterclockwise at this time, that is, the carrier 1 moves to the left, and the flat discharge port a is inserted into the gap between the edge of the asphalt pavement and the curb, and is located in the lower layer of the gap. At this time, the flat discharge port a is aligned with the road section L1, and only the open end of the flat discharge port a is in the discharge state, so that there is no material in the gap that blocks the rotation of the flat discharge port a. As the material spreading barrel 3 rotates, the carrier 1 also moves, and the material spreading barrel 3 gradually rotates to Figure 10 In the state (B), the side plate 42 is gradually opened, so that the opening side can also gradually discharge the material until it reaches Figure 10 In the (C) state, Figure 10 In the process from state (B) to state (C), the opening side is gradually away from the gap, so it can fill the upper layer of section L1. At this time, the flat discharge port b is facing section L2. As the spreading barrel 3 rotates, the flat discharge port a is Figure 10 From the state (C) in the figure to the state (D), the side plate 42 is in a state of gradual closing. It should be noted that during the gradual closing process, it is still in the discharging state, and at this time the upper layer of the material in the gap of the L1 section does not prevent the side plate 42 from closing. Figure 10 In (C), the round materials are already filled in the gap, and the oval materials are being discharged. In this state, the carrier 1 will move to the left while the spreading barrel 3 rotates, and the side plate 42 is in a state of moving to the left. Therefore, the round materials will not block the return of the side plate 42, or will only slightly block it until the side plate 42 is completely closed.
[0056] The above process can achieve the purpose of layered material spreading in the gap without stopping the vehicle; as the spreading barrel 3 rotates, the next stroke of spreading material begins facing the flat discharge port b of the section L2, so that the section L2 can also be layered.
[0057] like Figures 1-6 As shown, in order to assemble the spreading barrel 3 on the carrier 1, a connecting frame 9 is provided, and the spreading barrel 3 is assembled on the connecting frame 9. A protruding frame is provided in the area above the spreading barrel 3 on the carrier 1, and a cylinder 14 is installed on the protruding frame. The connecting frame 9 is a U-shaped structure, straddling above the spreading barrel 3. The cylinder 14 is used to drive the connecting frame 9 to rise or fall, thereby raising or lowering the spreading barrel 3. When the spreading barrel 3 is lowered, the flat discharge port 41 is inserted into the gap at the edge of the curb for filling. When the filling is completed, the cylinder 14 drives the spreading barrel 3 to rise, so that the flat discharge port 41 is higher than the ground, so that the carrier 1 can move normally on the road surface.
[0058] Specifically, a central axis 31 is provided at the center of the two sides of the spreading barrel 3 , and the central axis 31 is installed on the connecting frame 9 .
[0059] In order to realize the automatic opening and closing of the side plate 42 in each filling stage, please refer to Figure 7-Figure 9 as well as Figure 11-13 As shown, the transmission mechanism includes a first gear 51 , a fixed plate 55 , an inner gear ring 56 and an outer gear ring 57 , and the fixed plate 55 is fixed on the inner side of the connecting frame 9 .
[0060] The number of the first gears 51 is the same as the number of the flat discharge ports 41. The first gears (51) are rotatably mounted on one side of the spreading barrel 3 via a rotating shaft 59. Preferably, the first gears 51 are located on the side of the spreading barrel 3 close to the carrier 1 and correspond one to one with the side plate 42. A second connecting rod 52 is fixed to the side of the first gear 51 close to the spreading barrel 3. One end of the second connecting rod 52 is fixedly connected to the side plate 42 via the first connecting rod 43. Therefore, when the first gear 51 rotates, the second connecting rod 52 thereon can drive the first connecting rod 43 to rotate a certain angle, so that the first connecting rod 43 can cause the side plate 42 to deflect relative to the opening side, that is, the side plate 42 can open and close.
[0061] In order to enable the first gear 51 to rotate when corresponding to the road section L1, the fixed disc 55 is located on both sides of the spreading barrel 3. The fixed disc 55 close to the first gear 51 is used to drive the first gear 51 to rotate. Specifically, the fixed disc 55 close to the first gear 51 is fixed with an inner gear ring 56 and an outer gear ring 57. The teeth of the inner gear ring 56 are arranged on one side below the side plate 42, and the outer gear ring 57 is arranged on the other side below the side plate 42 (refer to Figure 10 , the inner gear ring 56 is located directly below, and the outer gear ring 57 is located at the lower right, that is, the outer gear ring 57 is located on the side away from the traveling direction of the vehicle 1). The first gear 51 can be engaged with the inner gear ring 56 and the outer gear ring 57 in stages. The first gear 51 located at the bottom (with Figure 10 The flat discharge port a in the figure first meshes with the teeth of the inner gear ring 56 to generate meshing force to drive the first gear 51 to rotate, thereby driving the side plate 42 to gradually open, so that the material can be discharged through the opening side. As the spreading barrel 3 rotates, the first gear 51 rotates to the rightmost end of the inner gear ring 56, and the side plate 42 of the flat discharge port 41 opens to the maximum angle. The first gear 51 then meshes with the teeth of the outer gear ring 57 to generate meshing force to drive the first gear 51 to rotate in the opposite direction, thereby driving the side plate 42 to gradually close until the side plate 42 deflects and resets. At this time, the flat discharge port a completes the filling work of the gap position in this section.
[0062] See also Figure 7-Figure 9 as well as Figure 11-13As shown, in order to achieve stable closure of the side plate 42 in the non-filling area, a third connecting rod 53 is further provided. The third connecting rod 53 is fixed to one side of the first gear 51, and a slider 54 is fixed at one end of the third connecting rod 53. A sliding groove 58 cooperating with the sliding groove 54 is provided on the fixed disk 55. The sliding groove 58 is distributed in the area of the fixed disk 55 that is staggered with the inner gear ring 56 and the outer gear ring 57. The two ends of the sliding groove 58 are ports 581. When the sliding block 54 slides in the sliding groove 58, the sliding block 54 is limited in the radial direction of the spreading barrel 3, thereby limiting the rotation of the first gear 51 through the third connecting rod 53, achieving the fixed angle of the first gear 51, and then the fixed angle of the side plate 42, which can achieve stable closure of the side plate 42 in the non-filling area.
[0063] The reason why the slide groove 58 is staggered with the inner gear ring 56 and the outer gear ring 57 is to provide free space for the slider 54. The free space is between the two ports 581, and the free space does not limit the slider 54. Therefore, when the first gear 51 is engaged with the inner gear ring 56 and the outer gear ring 57, the slider 54 is no longer restricted, that is, the slider 54 deflects as the angle of the first gear 51 changes. Since in this embodiment, the angle of rotation of the first gear 51 on the inner gear ring 56 is set to be the same as the angle of rotation of the first gear 51 on the outer gear ring 57, after the angle of the slider 54 is deflected, it is deflected and reset, and it can re-enter the slide groove 58 through the port 581.
[0064] Preferably, the port 581 is configured as a bell mouth to improve the fault tolerance after the slider 54 is deflected and reset, thereby ensuring that the slider 54 can re-enter the slide groove 58 from the free space.
[0065] See also Figure 11-12 Since the material is likely to form bridges in the spreading barrel 3 and the flat discharge port 41 during the actual operation of the device, the present embodiment provides the following solution: one end of the rotating shaft 59 is extended to the inside of the spreading barrel 3 and a cam 81 is fixedly sleeved thereon. T-shaped hammers 82 are fixedly connected to both sides of the cam 81. The T-shaped hammers 82 correspond to the positions of the flat discharge port 41. During the filling process, for example Figure 10 The flat discharge port a in the middle, the first gear 51 thereon can rotate under the action of the inner gear ring 56 and the outer gear ring 57, and its rotation drives the rotating shaft 59 to rotate. The T-shaped hammer 82 rotates with the rotating shaft 59 to forcibly push the material of the flat discharge port 41, realizing mechanical arch breaking, reducing the material in the discharge process due to its own viscosity, friction, electrostatic force or irregular shape, etc., forming a stable "arch bridge" structure at the flat discharge port 41, resulting in the bridging phenomenon that the material cannot fall or flow smoothly, ensuring smooth material discharge.
[0066] See also Figure 4-Figure 9In order to achieve the same rotation direction of the wheels of the spreading barrel 3 and the carrier 1, the central axis 31 of the spreading barrel 3 is rotatably connected to the fixed plate 55 through a bearing. A driving mechanism 7 is provided on the side of the spreading barrel 3 close to the carrier 1. The driving mechanism 7 includes a motor 71. The power output end of the motor 71 is fixedly connected to the second gear 72. The central axis 31 close to the carrier 1 passes through the fixed plate 55 and is sleeved with a third gear 73. The second gear 72 is meshed with the third gear 73. When the motor 71 is started, its power output end drives the second gear 72 to rotate. The rotation of the second gear 72 generates a meshing force with the third gear 73 to drive the third gear 73 to rotate, that is, the central axis 31 rotates to realize the rotation of the spreading barrel 3. The speed of the spreading barrel 3 can be adjusted by adjusting the speed of the motor 71, that is, the spreading speed is adjusted, and this speed is close to the moving speed of the carrier 1.
[0067] See also Figure 7-Figure 9 as well as Figure 14-15 As shown, in order to enable only the flat discharge port 41 located at the lower part to discharge material, an inner cylinder 61 is provided inside the spreading barrel 3, and an inclined discharge port cooperating with the flat discharge port 41 is opened at the lower part of the inner cylinder 61, so that the material inside the spreading barrel 3 can only be discharged from the flat discharge port 41 located inside the gap at the lower part through the inclined discharge port. At this time, the inclined discharge port corresponds to the flat discharge port 41 as a filling component, and the blocking part of the inner cylinder 61 is a non-filling component, that is, the inner cylinder 61 blocks the flat discharge port 41 in the non-filling area from discharging material, thereby avoiding the centrifugal force of the rotation of the spreading barrel 3 causing the material to be thrown out and scattered everywhere, resulting in waste of material.
[0068] Since the device is in the non-filling state, the flat discharge port 41 below needs to be closed ( Figure 10 The flat discharge port a) in the middle is used to avoid leakage of materials in the non-filling state. A mounting shaft 62 is fixed on one side of the inner cylinder 61. The mounting shaft 62 passes through the middle axis 31 and is sleeved with a worm gear 63. A worm 64 is meshingly connected to the worm gear 63. A handle 65 is provided at the lower end of the worm gear 64. The worm gear 64 is rotated by rotating the handle 65. The rotation of the worm gear 64 generates a meshing force with the worm gear 63 to drive the worm gear 63 to rotate, and then the mounting shaft 62 drives the inner cylinder 61. At the beginning and end of the filling work, the discharge and non-discharge can be controlled by rotating the inner cylinder 61 to tilt the discharge port downward or upward.

[0070] See also Figure 1-Figure 2After filling the gaps between the curb stones, the edge gaps need to be rolled. Therefore, a first pressing roller 12 and a second pressing roller 13 cooperating with a spreading barrel 3 are provided on one side of the carrier 1 in sequence. After the spreading barrel 3 fills the gaps between the curb stones, the first pressing roller 12 behind it rolls through the gaps between the curb stones to perform preliminary and precise compaction on the loose materials in the gaps, reducing the spaces between the material particles. After that, the second pressing roller 13 rolls to perform a secondary rolling operation on the gaps between the asphalt pavement and the curb stones, thereby improving the density, bearing capacity and stability of the materials, making the road surface and the gap height consistent, and avoiding subsequent structural damage.
[0071] During use, the material is poured into the feed hopper 2, and the vibration motor 11 allows the material to enter the spreading barrel 3 evenly and continuously through the connecting pipe 10. The cylinder 14 is started to insert the flat discharge port 41 into the gap on the edge of the curb for filling. The handle 65 is turned to drive the worm 64 and the worm wheel 63 to generate a meshing force to drive the inner barrel 61 to rotate, so as to adjust the inclined discharge port downward so that the flat discharge port 41 at the bottom can discharge the material. At the same time, the carrier 1 is started and the direction is controlled manually to provide a stable mobile platform for the filling operation of the spreading barrel 3. The driving mechanism 7 is started to drive the spreading barrel 3 to rotate and carry out the filling work. At this time, the rotation direction of the spreading barrel 3 is the same as the rotation direction of the wheels of the carrier 1.
[0072] During the filling process, the flat discharge port a is inserted into the gap and located at the lower layer of the gap. First, the lower layer of the section L1 is filled, as shown in the following example. Figure 10 In the state (A), as the spreading barrel 3 rotates and the carrier 1 moves, the spreading barrel 3 gradually rotates to Figure 10 In the states (B), (C), and (D), the flat discharge port a is always approximately located above the road section L1, which can achieve the purpose of layered material spreading in the gap without stopping the vehicle. As the spreading barrel 3 rotates, the flat discharge port b facing the road section L2 starts the next stroke of material spreading, so that the road section L2 can also be layered.
[0073] At the same time, the spreading barrel 3 is Figure 10 The state (A) gradually turns to Figure 10 In the state (B), the first gear 51 located at the bottom (with Figure 10 The flat discharge port a in the middle first meshes with the teeth of the inner gear ring 56 to generate meshing force to drive the first gear 51 to rotate, and then drive the side plate 42 to gradually open, so that the opening side can also gradually discharge the material until it reaches Figure 10 In the state (C), the first gear 51 rotates to the rightmost end of the inner gear ring 56, and the side plate 42 of the flat discharge port a is opened to the maximum angle. Figure 10From state (C) in the figure to state (D), during this process, the first gear 51 meshes with the teeth of the outer gear ring 57 to generate meshing force to drive the first gear 51 to rotate in the opposite direction, thereby driving the side plate 42 to gradually close until the side plate 42 deflects and resets. At this time, the flat discharge port a completes the filling work of the gap position in this section. After resetting, the slider 54 of the third connecting rod 53 is stuck in the slide groove 58 and slides. The slider 54 is limited in the radial direction of the spreading barrel 3, thereby limiting the rotation of the first gear 51 through the third connecting rod 53, realizing the fixed angle of the side plate 42, and realizing the stable closure of the side plate 42 in the non-filling area, so that the flat discharge port a can stably participate in the next filling work.
[0074] At the same time, during the filling process, the first gear 51 can rotate under the action of the inner gear ring 56 and the outer gear ring 57, and its rotation drives the rotating shaft 59 to rotate. The T-shaped hammer 82 rotates with the rotating shaft 59 to forcibly push the material out of the flat discharge port 41, thereby achieving mechanical arch breaking and reducing the occurrence of bridging during the discharge process.
[0075] After the spreading barrel 3 fills the gap at the edge of the curb, the first pressure roller 12 located behind it rolls through the gap at the edge of the curb and performs preliminary precise compaction operations on the loose materials in the gap to reduce the gaps between the material particles. Then the second pressure roller 13 rolls to perform a secondary rolling operation on the gap between the asphalt pavement and the edge of the curb to improve the density, bearing capacity and stability of the material, so that the road surface and the gap are highly consistent, avoiding subsequent structural damage.
[0076] At the end of filling, the inner cylinder 61 is rotated by rotating the handle 65 to adjust the inclined discharge port to be located upward in the non-filling area so that no material is discharged. At the same time, the cylinder 14 drives the spreading barrel 3 to rise so that the flat discharge port 41 is higher than the ground. At this time, the carrier 1 can move normally on the road.
[0077] On the other hand, the present invention also provides a method for constructing a filler in the gap between the edge of an asphalt pavement and a curb, comprising the following steps:
[0078] Step 1: Align the flat discharge port 41 with the curb gap, and control the cylinder 14 to insert the lowest flat discharge port 41 into the curb gap;
[0079] Step 2: Turn on the driving mechanism 7 to start the spreading barrel 3 to rotate, and at the same time push the carrier 1 to move. The rotation direction of the spreading barrel 3 is the same as the rotation direction of the wheels of the carrier 1 to compensate for the movement of the carrier 1. When the spreading barrel 3 rotates, the open end of the flat discharge port 41 at the bottom faces the lower filler in the gap. When the flat discharge port 41 initially leaves the gap, the side plate 42 opens so that the opening side can also discharge material, so that the opening side faces the upper filler in the gap, and when the spreading barrel 3 continues to rotate, the side plate 42 closes, and the flat discharge port 41 no longer discharges material.
