Description

Technical Field

[0001] The present invention relates to municipal construction equipment, and particularly to a curb laying mechanism. Background Art

[0002] With the development of the current urban construction level, the requirements for municipal road surfaces are getting higher and higher. Large areas of flat floor tiles and curbs usually need to be laid in places such as sidewalks and squares. At present, the laying of floor tiles and curbs generally adopts pure manual operation or a combination of machinery and manual labor. The construction method of the combination of machinery and manual labor is as follows: The bricks are lifted by a rope through a crane, then the landing position is manually controlled and the bricks are unloaded, and finally the pressing operation is carried out. This laying method is time-consuming and laborious. The laying effect depends on the technical level of the construction workers. At the same time, the labor intensity of the workers is high, and more construction workers are required, which increases the laying cost.

[0003] The curb needs to be vertically laid on the ground, and there is currently no laying mechanism specifically for curbs. Summary of the Invention

[0004] The present invention aims to provide a curb laying mechanism, which is detachably installed on a brick laying machine. The length direction of the brick laying machine is the X direction, and the width direction is the Y direction. A vertical guard plate in the Y direction is installed on the front side of the curb laying frame, and width adjusting plates perpendicular to the back surface of the vertical guard plate are installed on both sides of the curb laying frame. The distance between the two width adjusting plates is adjustable;

[0005] A buffer plate is installed above the rear side between the two width adjusting plates. The buffer plate is flipped towards the vertical guard plate with a horizontal rotating shaft in the Y direction. A guiding slope plate is fixed between the vertical guard plate and the buffer plate. There is a gap between the front end of the guiding slope plate and the vertical guard plate. The back surface of the buffer plate supports the curbs transmitted from the rear. The buffer plate is flipped downward to make the curbs fall onto the guiding slope plate. The curbs slide down on the guiding slope plate into the gap and stand vertically on the ground in the Y direction.

[0006] Further, the two width adjusting plates are installed on the curb laying frame through a first adjustable guide rail in the Y direction. The width adjusting plates are vertical plates in the X direction and are provided with folded edges bent outward at the rear end.

[0007] Further, the curb laying frame is provided with thickness positioning mechanisms on both sides of the vehicle width, and the width adjusting plates are located in the middle of the thickness positioning mechanisms;

[0008] The thickness positioning mechanism includes a thickness adjustment plate in the Y direction. The thickness adjustment plate in the Y direction is installed on the curb paving frame through a second adjustable guide rail in the X direction. The front and rear positions of the thickness adjustment plate in the X direction are adjustable. A horizontal thickness positioning wheel is fixed at the bottom of the thickness adjustment plate. During the paving process of the paver, the thickness positioning wheel at the rear end in the traveling direction abuts against the back side wall of the laid curb.

[0009] Furthermore, soil crushing and cleaning plates are symmetrically installed on the left and right sides of the vehicle width of the curb paving frame. Two width adjustment plates are located between the thickness positioning mechanisms on both sides. The top end of the soil crushing and cleaning plate is hinged on the curb paving frame to rotate in the Y direction. The cross-section of the soil crushing and cleaning plate in the X direction is a right triangle. One of the straight sides of the right triangle is close to the width adjustment plate on the same side, and the other straight side is in contact with the ground.

[0010] Furthermore, vertical rolling wheels are arranged on the straight side of the soil crushing and cleaning plate close to the width adjustment plate. During the process of the paver paving the curb in the Y direction, the soil crushing and cleaning plate at the front end in the traveling direction is in a hanging state for cleaning the soil in the curb paving groove, and the soil crushing and cleaning plate at the rear side in the traveling direction is flipped to a horizontal state and the rolling wheels roll on the upper surface of the laid curb.

[0011] Furthermore, a vertical plate perpendicular to the ground and parallel to the vertical guard plate is provided at the front end of the guiding ramp plate. The distance between the vertical plate and the vertical guard plate is equivalent to the thickness of the curb.

[0012] With the aid of this mechanism, the curb conveyed by the paver can be vertically paved on the ground automatically. At the same time, this mechanism also has the following advantages:

[0013] 1) Adjustable width: The distance between the width adjustment plates is adjustable to adjust the width of the curb paving opening to adapt to the paving of curbs with different lengths.

[0014] 2) Adjustable thickness: By adjusting the position of the thickness positioning wheel in the Y direction through the width adjustment plate, the distance between the vertical guard plate and the front end of the thickness positioning wheel is made equal to the thickness of the curb, playing a role in thickness positioning. And the thickness positioning wheel provides a forward thrust for the erected curb, making the curb paving more neat.

[0015] 3) Soil crushing and cleaning plates are provided on the left and right sides of the frame. During the paving process, the front soil crushing and cleaning plate can clean the soil in the curb paving groove, and the rear soil crushing and cleaning plate can roll down the laid curb, making the paving height of the curb more consistent.

[0035] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, some technical features well known in the art are not described to avoid confusion with the present invention.

[0036] To thoroughly understand the present invention, detailed steps and detailed structures will be presented in the following description to explain the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below. However, in addition to these detailed descriptions, the present invention can also have other implementation manners.

[0037] Referring to Figure 1 as shown, the present invention provides a paving machine 10, as Figure 1 shown, the paving machine 10 includes a vehicle frame 11. A traveling device 12 is installed on the vehicle frame chassis. The traveling device 12 is provided with 4 steerable traveling wheels 13, and the traveling device 12 can drive the paving machine 10 to travel. For the convenience of the following description, we set the length direction of the vehicle frame 11 as the X direction and the width direction as the Y direction. The paving machine 10 moves in the Y direction to continuously lay the curbstone 001.

[0038] A lifting mechanism 100 and a clamping and pushing mechanism 200 are installed at the tail of the vehicle frame 11. A multi-axis robotic arm 500 is installed at the front of the vehicle frame 11. A curbstone laying mechanism 400 is installed on the robotic arm 500, and a conveying mechanism 300 located between the curbstone laying mechanism 400 and the clamping and pushing mechanism 200 is installed on the vehicle frame 11;

[0039] The lifting mechanism 100 is provided with a first transmission mechanism 104, a lifting plate 103, and a lifting device 120. The first transmission mechanism 104 transfers the stacked curbstones to the lifting plate 103 and drives the lifting plate 103 to lift upward by the lifting device 120;

[0040] The clamping and pushing mechanism 200 includes a forward moving guide rail 210 and a clamping device 220 slidably mounted on the forward moving guide rail 210. The clamping device 220 clamps both ends of the length of the curbstone after being lifted to the top, conveys it forward in the X direction, then releases it and places it flat on the conveying mechanism 300. The conveying mechanism 300 conveys the curbstone forward in the X direction to the curbstone laying mechanism 400.

[0041] The curbstone laying mechanism 400 is provided with a curbstone laying frame 410 mounted on the mechanical boom 500. A curbstone laying opening 411 with adjustable width in the Y direction is arranged in the middle of the curbstone laying frame 410. A vertical guard plate 416 in the Y direction is installed on the front side of the curbstone laying opening 411. A buffer plate 420 that can be turned downwards is installed on the rear side of the curbstone laying opening 411. A guiding ramp plate 413 is fixed between the vertical guard plate 416 and the buffer plate 420. The buffer plate 420 supports the curbstone conveyed by the conveying mechanism 300, and the buffer plate 420 that is turned downwards sends the curbstone 001 lying flat on the conveying mechanism 300 to the guiding ramp plate 413. The curbstone 001 slides down on the guiding ramp plate 413 and stands upright on the ground in the Y direction.

[0042] For the brick laying machine 10 of the present invention, the stacked curbstones are lifted as a whole by the lifting mechanism 100. Subsequently, the clamping and pushing mechanism 200 clamps and transfers the curbstones one by one and places them flat on the conveying mechanism 300. The conveying mechanism 300 transports the curbstones placed flat to the curbstone laying mechanism 400, and the curbstone laying mechanism 400 vertically lays the curbstones in the curbstone laying groove. The whole process is fully mechanized, greatly improving the laying efficiency and reducing the required labor cost at the same time. At the same time, when laying the curbstones, this device does not require manual assistance, and the operators do not need to participate in heavy work, reducing the labor intensity of people.

[0043] The structure of the lifting mechanism 100 will be further described below:

[0044] The lifting mechanism 100 is provided with a longitudinal lifting bracket 102 installed at the tail of the vehicle frame 11. The first transmission mechanism 104 is fixedly installed at the bottom of the longitudinal lifting bracket 102. The lifting plate 103 is driven by a lifting device 120 on the longitudinal lifting bracket 102 to move up and down in the vertical direction of the first transmission mechanism 104. The lifting plate 103 is provided with an opening groove corresponding to the position of the first transmission mechanism 104 so that the lifting plate 103 can be lowered below the upper surface of the first transmission mechanism 104. A storage bracket 130 is installed at the bottom of the rear side of the lifting bracket. The front end of the storage bracket 130 is rotatably connected to the bottom of the rear side of the longitudinal lifting bracket 102. The storage bracket 130 can be turned up and down with the front end as the rotation point and folded for storage (as Figure 3b and 3cAs shown, a second transmission mechanism 132 is provided on the storage bracket 130; the storage bracket 130 conveys the stacked curb stones forward in the X direction to the first transmission mechanism 104, and the first transmission mechanism 104 continues to convey the curb stones forward onto the lifting plate 103.

[0045] In an alternative embodiment, lifting devices 120 are installed on the longitudinal lifting bracket 102 and are located on both sides of the lifting plate 103 in the Y direction. Each lifting device 120 includes a lifting cylinder 121 and a lifting chain 122. The lifting cylinder 121 is vertically fixed on the longitudinal lifting bracket 102; both ends of the lifting chain 122 are fixedly connected to the lifting plate 103 and the top rod of the lifting cylinder 121 respectively, or both ends of the lifting chain 122 are located on both sides of the lifting cylinder 121 and straddle the top rod of the lifting cylinder 121. One end of the lifting chain 122 is fixedly connected to the lifting plate 103, and the other end is fixed on the longitudinal lifting bracket 102 on one side of the lifting cylinder 121. The upward sliding of the top rod of the lifting cylinder 121 drives the end of the lifting chain 122 to move upward, and the two sets of lifting chains 122 drive the middle lifting plate 103 to be steadily lifted.

[0046] In an alternative embodiment, vertical guiding channel steel rails 105 are provided on the longitudinal lifting bracket 102 and are located on both sides of the lifting plate 103. Lifting webs 106 are slidably installed up and down on each vertical guiding channel steel rail 105. One end of the lifting chain 122 and the lifting plate 103 are both fixedly connected to the lifting web 106.

[0047] In an alternative embodiment, the storage bracket 130 is installed at the bottom of the longitudinal lifting bracket 102 through a reset flipping bracket 131, and a spring support 135 is installed at the bottom of the longitudinal lifting bracket 102;

[0048] A limiting steel pipe 138 and a reset spring 137 are installed at the bottom of the reset flipping bracket 131,

[0049] The limiting steel pipe 138 sequentially passes through two baffle plates 136 on the back of the reset flipping bracket 131 and is rotatably connected to the spring support 135. The reset spring 137 is sleeved on the limiting steel pipe 138 between the two baffle plates 136;

[0050] The transverse width of the storage bracket 130 is smaller than the transverse width of the longitudinal lifting bracket 102, and the storage bracket 130 is rotatably connected to the center of the bottom of the longitudinal lifting bracket 102.

[0051] The lifting mechanism 100 adopts the forklift lifting principle. The lifting cylinders 121 and the lifting chains 122 are placed on the left and right sides in combination. One end of the chain is connected to the vehicle frame, and the other end is connected to the brick lifting plate 103. Bearings are installed on both the left and right sides of the lifting plate 103, and it can roll up and down on the vertical guiding channel steel track 105. A second transmission mechanism 132 is provided on the storage bracket 130. The second transmission mechanism 132 is composed of rollers, sprocket chains, drive motors, etc., to realize the reception and transmission of bricks. After the operation is completed, the storage bracket 130 can rotate 90 degrees in the vertical plane, as Figure 3c shown, to reduce the floor space.

[0052] Combined shown, the design highlights of the lifting mechanism 100 are as follows: 1) The design of the storage and lifting parts can ensure the continuous supply of bricks, meet the front-end brick demand, improve efficiency, and the structure is compact. 2) The lifting part design can accurately lift the corresponding height according to the thickness of the bricks. 3) When placing materials with a forklift in the design, the clamping opening formed by the two end plates of the forklift corresponds to the storage vertical plate, and the width of the storage vertical plate is much smaller than the width of the clamping opening, which can be applied to various types of forklifts, facilitating the placement and transportation of large and small bricks, and the operation is very convenient. 4) When the storage materials complete the operation, the storage vertical plate can be manually pushed and rotated upward by 90°, and the storage part is retracted to the vertical state, reducing the overall length of the vehicle, facilitating transfer and transportation. And when the storage mechanism is placed flat, its storage outer frame and the vehicle frame can be self-limited to support its flat state. The spring assembly realizes the easy placement and retraction of the storage structure.

[0053] Next, with reference to Figures 3a - 3d shown, the structure of the clamping and pushing mechanism 200 will be further described:

[0054] The forward movement guide rail 210 is provided with two first slide rails 211 in the X direction. Upper rails 212 are provided on the relative inner sides of the first slide rails 211. Lower lifting rails 213 are provided on the first slide rails 211 below the upper rails 212. Front and rear inlet openings 213-1 facing downward are provided on the lower side edges of the lower lifting rails 213. A pair of front and rear first rollers 202 are installed in each upper rail 212. Second rollers 221 are respectively fixed at the front and rear ends on both sides of the clamping device 220. The corresponding first rollers 202 and second rollers 221 are movably connected by a connecting rod 230. The first horizontal movement propulsion cylinder 240 drives the first rollers 202 to slide forward in the upper rail 212 to drive the clamping device 220 to move forward horizontally. During the forward sliding process of the first rollers 202, the second rollers 221 are driven by the connecting rod 230 to enter the lower lifting rail 213 through the inlet opening 213-1 to lift the height of the clamping device 220.

[0055] In an alternative embodiment, a pair of front and rear first rollers 202 within the upper track 212 are both mounted on a side push plate 214. The side push plate 214 is fixedly connected to the ejector rod of the first lateral translation propulsion cylinder 240. The first lateral translation propulsion cylinder 240 pushes the side push plate 214 to drive the pair of front and rear first rollers 202 to roll back and forth within the upper track 212.

[0056] The upper and lower ends of the connecting rod 230 are respectively hinged to the first roller 202 within the upper first slide rail 211 and the second roller 221 of the clamping device, with a total of four hinge points, thereby forming a parallelogram linkage mechanism (such as the rectangular dotted line frame in Figures 4a - 4f ). That is, the four corners of the clamping device are respectively movably connected below the first slide rail 211 through the connecting rod 230; the second roller 221 is rotatably mounted on the frame of the clamping device 220. During specific operation, the first lateral translation propulsion cylinder 240 drives the side push plate 214 to drive the first roller 202 to roll forward within the upper track 212. The lower end of the connecting rod 230 drives the clamping device 220, forming a parallelogram linkage mechanism to achieve the forward push of the entire clamping mechanism. Before the clamping device 220 slides forward, the second roller 221 provided on the clamping device 220 first enters the lower lifting track 213 to thereby lift the height of the clamping device 220. Therefore, the height of the curbstone clamped by it will also increase, avoiding friction between the clamped brick and the curbstone below it and scratching the surface of the brick, as shown in Figure 4d . The clamping device 220 first lifts a little height and then moves forward. Preferably, when the clamping device 220 is at the position at the end of the stroke, both of the two second rollers 221 are exactly located at the entrance of the lower lifting track 213, enabling the clamping device 220 to first lift the height and then slide forward.

[0057] As shown in Figure 4e , the clamping device 220 includes a clamping frame 223. The clamping frame 223 is provided with a second slide rail 224 in the Y direction and a multi-link linkage mechanism. On the second slide rail 224, there are two relatively slidable clamping plates 225. The multi-link linkage mechanism consists of a middle swing rod 226 and two clamping connecting rods 227 hinged at both ends of the swing rod 226. The center of the swing rod 226 is rotationally connected to the clamping frame 223 through a swing rod center pin. The other ends of the two clamping connecting rods 227 are respectively hinged to the opposite faces of the two clamping plates 225; one end of the swing rod 226 is hinged to the clamping drive cylinder 228. The clamping drive cylinder 228 drives the multi-link linkage mechanism to drive the two clamping plates 225 to slide relatively or towards each other on the second slide rail 224 to clamp or release the curbstone.

[0058] By adopting the above multi-link linkage mechanism, only one clamping drive cylinder 228 can be used to make the two clamping plates 225 slide relatively or in opposite directions on the second slide rail 224 at the same time to clamp or release the curbstone, which simplifies the drive structure. On the other hand, the movements of the two clamping plates 225 are synchronized, making the clamping and releasing actions more linear. Preferably, rubber plates are detachably installed on the opposite surfaces of the two clamping plates 225 to protect the floor tiles when clamping the floor tiles.

[0059] In an alternative embodiment, the conveying mechanism 300 is a conveying mechanism based on rollers or belts.

[0060] The structure of the curbstone laying mechanism 400 will be further described below:

[0061] Two quick-release interfaces 417 are provided on the curbstone laying frame 410, which facilitates the detachable installation of the curbstone laying frame 410 on the quick-release mounting bracket 531 of the mechanical boom 500 at the front end of the brick laying machine. Width adjustment plates 412 are symmetrically installed on both sides of the vehicle width of the curbstone laying frame 410 (the opening area between the two width adjustment plates 412 is the curbstone laying opening 411). The width adjustment plates 412 pass through the first adjustable guide rail 418 in the Y direction and are fixed to the curbstone laying frame 410 through the adjustment plate 414. The adjustment plate 414 is provided with a plurality of fixing holes, and the distance between the two width adjustment plates 412 can be adjusted through different fixing holes, so as to realize the manual adjustment of bricks with different lengths. Preferably, the width adjustment plate 412 is a vertical plate in the X direction and is provided with a folded edge 415 bent outward at the rear end to play a guiding role.

[0062] A thickness adjustment component is provided on the curbstone laying frame 410 to realize the automatic elastic adjustment of bricks with different thicknesses. Its specific structure is as follows: Horizontally arranged thickness positioning wheels 430 are symmetrically installed on both sides of the vehicle width of the curbstone laying frame 410. During the laying process of the curbstone laying equipment, the thickness positioning wheel 430 at the rear end in the traveling direction abuts against the back side wall of the laid curbstone. The thickness positioning wheel 430 is fixed on a thickness adjustment plate 431. The thickness adjustment plate 431 is a vertical plate in the Y direction. The thickness adjustment plate 431 is fixed to the curbstone laying frame 410 through the second adjustment guide rail 433. A thickness adjustment spring 432 is arranged on the second adjustment guide rail 433. Among them, the front and rear positions of the thickness adjustment plate 431 in the X direction are adjustable, so as to adjust the distance between the thickness positioning wheel 430 and the vertical guard plate.

[0063] The function of the buffer plate 420 is to buffer the falling bricks. Its rotating shaft is a horizontal rotating shaft in the Y direction. Both ends of the horizontal rotating shaft are connected to the curbstone laying frame 410, and a buffer spring 421 is installed on the horizontal rotating shaft between the curbstone laying frame 410 and the buffer plate 420.

[0064] The curb laying frame 410 is equipped with soil breaking cleaning plates 440 on both the left and right sides of the vehicle width. The top ends of the soil breaking cleaning plates 440 are hinged to the curb laying frame 410 to rotate in the Y direction. A rolling wheel 441 is installed on the soil breaking cleaning plate 440. The cross-section of the soil breaking cleaning plate 440 in the X direction is a right triangle, and the outer side is an inclined plane. During the paving process of the brick paving machine, the soil breaking cleaning plate 440 at the front end in the traveling direction is in a drooping state to clean the broken soil in the curb laying groove, and the soil breaking cleaning plate 440 at the rear side in the traveling direction is flipped upward to a horizontal arrangement, and the rolling wheel 441 rolls on the upper surface of the laid curb.

[0065] A guiding ramp plate 413 is fixed between the vertical guard plate 416 and the buffer plate 420. The front end of the guiding ramp plate 413 is provided with a vertical plate 413-1 that is perpendicular to the ground downward and parallel to the vertical guard plate 416. A gap slightly larger than the thickness of the curb is left between the vertical plate 413-1 and the vertical guard plate 416. The curb 001 falls onto the guiding ramp plate 413 by the downward flipping of the buffer plate 420, and the curb 001 slides downward on the guiding ramp plate 413 into the gap and stands upright on the ground in the Y direction.

[0066] The structure of the mechanical boom 500 will be further described below:

[0067] A mechanical boom 500 is symmetrically installed on both the left and right sides of the front part of the vehicle frame 11. The two mechanical booms 500 are fixedly connected by a connecting rod 540. Vertical guide rails 501 and horizontal guide rails 503 are fixed on both the left and right sides of the front part of the vehicle frame 11. A vertically sliding vertical slider support 502 is installed on the vertical guide rail 501, and a horizontally sliding horizontal slider 504 is installed on the horizontal guide rail 503; the vertical slider support 502 is connected to a vertical lifting mechanism 505 fixed to the front part of the vehicle frame 11, and the horizontal slider 504 is connected to a horizontal pushing mechanism 506 fixed to the front part of the vehicle frame 11. The vertical lifting mechanism 505 and the horizontal pushing mechanism 506 are any one of a cylinder, a hydraulic cylinder, an electric push rod, and a screw jack.

[0068] The mechanical boom 500 includes a longitudinal leg 530, a horizontal upper arm 510, and a lower arm 520. The front ends of the upper arm 510 and the lower arm 520 are both hinged to the leg 530. The rear end of the upper arm 510 is hinged to the vertical slider support 502. The lower arm 520 is fixedly connected to the horizontal slider 504, and the rear end of the lower arm 520 is movably connected to the upper arm 510 through a connecting rod support arm 521. As Figure 4cAs described above, the upper arm 510, the lower arm 520, the outrigger 530, and the link support arm 521 form a parallelogram structure (as shown by the dashed line). The advantage of the parallelogram structure is that the outrigger at the front side can be better controlled by the rear vertical lifting mechanism 505 and the horizontal pushing mechanism 506. A quick-release mounting bracket 531 is installed at the bottom of the outrigger 530. A swing cylinder 532 is connected between the quick-release mounting bracket 531 and the outrigger 530. A quick-release first support universal wheel 533 is installed at the bottom of the quick-release mounting bracket 531.

[0069] As Figure 5b Figure 5a shown, the quick-release mounting bracket 531 is provided with two rotating shafts. The first rotating shaft is installed on the outrigger 530 through a pin shaft 531-2. The second rotating shaft 531-6 is hingedly connected to the swing rod of the swing cylinder 532. The swing cylinder 532 drives the quick-release mounting bracket 531 to rotate around the pin shaft 531-2 as the axis.

[0070] The quick-release mounting bracket 531 is provided with two triangular plates 531-1 arranged in parallel. The three vertices of the two triangular plates 531-1 are fixedly connected by connecting columns. The first connecting column is coaxially arranged with the pin shaft 531-2. The other two second connecting columns 531-7 are used to connect with the bayonet sockets reserved by the paving mechanism. The second rotating shaft 531-6 is arranged between two of the connecting columns; one of the second connecting columns is a smooth shaft, and the other second connecting column is a locking shaft 531-3 with a non-circular cross-section. One end of the locking shaft 531-3 is fixedly connected to the handle 531-4. After the interface 417 of the curbstone paving frame 410 is stuck on the smooth shaft and the locking shaft 531-3, and the handle 531-4 is rotated to make the locking shaft 531-3 rotate to clamp the paving mechanism, so that the paving mechanism and the quick-release mounting bracket 531 are locked and fixedly connected. A buckle 531-5 for fixing the handle 531-4 is arranged on the outer side of one of the triangular plates, which is used to keep the handle 531-4 fixed in the locked state.

[0071] The mechanical boom 500 can realize the longitudinal and vertical positioning of the curbstone paving mechanism 400 installed at the front part and provide support for it. Through the coordinated operation of the vertical lifting mechanism 505, the horizontal pushing mechanism 506 of the mechanical boom 500 and the swing cylinder 532, it can be ensured that the front-end curbstone paving mechanism 400 always maintains a horizontal state, which is convenient for soil crushing and cleaning, curbstone placement, curbstone rolling, etc.

[0072] A quick-release mounting bracket 531 is installed at the bottom of the outrigger 530, which is convenient for quick connection with the curbstone paving mechanism 400. The angle of the quick connection device can be adjusted through the telescopic movement of the swing cylinder 532, which is convenient for quickly positioning and combining with the connection structure of the curbstone paving mechanism 400 to realize quick installation and disassembly.

[0073] In some other embodiments, we can also remove the curb laying mechanism 400 from the mechanical boom 500 and replace it with other mechanisms. For example, replace the curb laying mechanism 400 with a mechanism for laying flat bricks, so as to meet different brick laying requirements. At the same time, the structures of the lifting mechanism 100, the clamping and pushing mechanism 200, and the conveying mechanism 300 on the vehicle frame do not need to be modified, which enhances the expandability of the present invention.

[0074] The working process of the present invention will be described in detail below:

[0075] First, stack the curbs 001 on the forklift forks, with the front and back sides of the stacked curbs 001 in contact. Then, lower the storage bracket 130 to a horizontal state and drive the forklift to transfer the curbs to the storage bracket 130. Since the storage bracket 130 is rotatably connected to the bottom center of the longitudinal lifting bracket 102, a space for the forklift to travel is formed on both sides of the storage bracket 130. When the forklift approaches the brick laying machine 10, the storage bracket 130 can extend into the center of the opening of the forklift forks. After the forklift drives into position, unload the curbs and leave.

[0076] The storage bracket 130 is provided with a roller or a belt transmission mechanism to convey the stacked curbs 001 forward to the lifting plate 103 of the lifting mechanism 100, and the first transmission mechanism 104 of the lifting mechanism 100 takes over to continue transporting the curbs 001 forward, so that the curbs 001 are completely located on the lifting plate 103. The ejector rods of the lifting devices 120 on both sides of the lifting plate 103 slide upward, and the ejector rods drive the lifting webs 106 on both sides to move upward steadily through the lifting chains 122, thereby lifting the height of the lifting plate 103.

[0077] The clamping device 220 of the clamping and pushing mechanism 200 slides backward towards the rear of the vehicle, and the clamping plates 225 clamp and fix the left and right ends of the uppermost curb 001. Then, the clamping device 220 moves towards the front of the vehicle. During the forward sliding process of the clamping device 220, the second roller 221 will slide into the lower lifting track 213 to raise its own height, so that the clamping device 220 slightly raises the height of the curb 001 while driving the curb 001 forward, avoiding scratching between the clamped curb 001 and the curb 001 on the lifting plate 103, thus affecting the appearance of the curb 001.

[0078] When the clamping device 220 slides on the forward sliding guide 210 above the conveying mechanism 300, the two clamping plates 225 are released, and the curb 001 falls onto the conveying mechanism 300, and the conveying mechanism 300 continues to convey the curb 001 forward.

[0079] When the curbstone 001 reaches the front end of the conveying mechanism 300, it is first blocked by the buffer plate 420 of the curbstone laying mechanism 400. The lower side of the curbstone 001 contacts the buffer plate 420. Subsequently, the buffer plate 420 flips downward, and the curbstone 001 slides down onto the guiding ramp plate 413 due to the loss of the blockage of the buffer plate 420. Under the action of gravity, the curbstone 001 slides forward on the guiding ramp plate 413. When falling from the guiding ramp plate 413, it is blocked by the vertical guard plate 416 and falls into the gap between the guiding ramp plate 413 and the vertical guard plate 416 and stands upright in the Y direction in the curbstone laying groove. At this time, the laying operation of one curbstone 001 is completed.

[0080] Subsequently, the traveling device 12 drives the paver 10 to traverse in the vehicle width direction. Two soil cleaning plates 440 are respectively arranged on both sides of the curbstone laying frame 410 in the vehicle width direction. Among them, the soil cleaning plate 440 located at the front side of the laying direction is in a hanging state. During the progress of the paver, the soil cleaning plate 44 shows more. The soil cleaning plate 440 can clean the soil in the curbstone laying groove, making the curbstone laying groove smoother to ensure that the subsequent curbstones fall into the laying groove more neatly as a whole. The soil cleaning plate 440 located at the rear side of the laying direction is rotated to a horizontal state. The roller 441 of the soil cleaning plate 440 rolls on the upper surface of the curbstone 001 at the rear side of the laying direction of the curbstone laying frame 410, and performs a downward rolling operation on the curbstone laid at the rear during the traverse of the paver 10; moreover, the thickness positioning wheel 430 located at the rear side of the laying direction abuts against the back of the curbstone laid at the rear, and provides a forward rolling operation on the curbstone by the thickness positioning wheel 430 during the traverse; by performing downward and forward rolling on the curbstone laid at the rear, the laid curbstone can be made more neat.

[0081] The mechanical boom 500 is used to support the curbstone laying mechanism 400. The curbstone laying mechanism 400 is installed between two quick-release mounting brackets 531 through a quick-release structure. When the paver is in a non-laying working state, the mechanical boom 500 slides upward along the vertical guide rail 501 to drive the curbstone laying mechanism 400 away from the ground and make it suspended, so as to play a role in protecting the curbstone laying mechanism 400; when the paver moves to the designated position, the mechanical boom 500 descends, and the horizontal pushing mechanism 506 drives the leg 530 to move horizontally back and forth to adjust the position of the curbstone laying mechanism 400 at the bottom of the mechanical boom 500.
