Description

Technical Field

[0001] This invention relates to the field of municipal road paving technology, and in particular to a transport vehicle for installing curb stones on municipal roads. Background Technology

[0002] During municipal road paving construction, curb stones (also known as kerbstones or curb stones) are difficult to transport due to their weight and size, significantly impacting installation efficiency. Currently, curb stone installation mainly adopts the traditional "centralized unloading + manual distribution" model: forklifts and other transport vehicles are used to place piles of curb stones at intervals along the road, and then workers move individual curb stones to the installation location by hand or with simple lifting tools. This method is labor-intensive, inefficient, and prone to causing back injuries to workers.

[0003] To reduce the labor intensity of workers, existing technologies have proposed some auxiliary handling tools. For example, patent document CN213681614U discloses a curbstone installation tool that uses the lever principle to manually hang the curbstone on the operating rod for short-distance transport. However, such auxiliary tools have obvious limitations: first, they can only transport one or a few curbstones at a time, and cannot achieve continuous transport of multiple curbstones; second, they rely on pure manual operation, limiting the transport distance and making them unsuitable for long-distance, dispersed operations along roads; and third, they lack the function of connecting with the installation process, requiring manual removal and adjustment of the installation position after the curbstone is in place, making it difficult to improve work efficiency.

[0004] In addition, cement mortar needs to be applied to the base layer before installing curb stones to ensure bonding strength and levelness. The transportation of mortar is also a key factor restricting construction efficiency. Because curb stone paving has the characteristics of "linear continuity, scattered points, and sporadic usage," that is, it is laid continuously along the longitudinal direction of the road, but the amount of mortar used at each installation point is small and needs to be replenished as needed according to the progress. Existing large-scale transportation equipment (such as mortar mixer trucks and belt conveyors) cannot be used due to poor mobility and minimum conveying capacity limitations. At present, the construction site mainly relies on manual carrying of mortar buckets or hand-pushed mortar carts for transportation, which has disadvantages such as low efficiency and high labor intensity for workers. Moreover, prolonged exposure of mortar can easily lead to moisture evaporation, affecting bonding performance, especially in high temperature or windy weather, making it difficult to guarantee quality.

[0005] In summary, existing technologies lack integrated construction equipment that can simultaneously solve the problems of efficient transportation of roadside stones and synchronous delivery of mortar. There is an urgent need to develop a special device that adapts to the linear construction characteristics of municipal roads and enables the coordinated operation of continuous transportation of roadside stones and precise supply of mortar, so as to reduce reliance on manual labor and improve paving quality and construction efficiency. Summary of the Invention

[0006] To overcome the aforementioned shortcomings of existing roadside stone transportation and paving methods, the technical problem to be solved by this invention is to provide a transportation vehicle for the installation of roadside stones in municipal roads that can achieve coordinated operation of continuous transportation of roadside stones and precise supply of mortar.

[0007] The technical solution adopted by this invention to solve its technical problem is: A transport vehicle for installing curb stones on municipal roads includes a cargo box and wheels. The cargo box has a mortar storage bin on its outer bottom and horizontal and vertical transport wheels driven by a drive mechanism on its inner bottom. A curb stone unloading port is located at the bottom corner of a side panel along the length of the cargo box. The horizontal transport wheels are positioned in the area directly opposite the curb stone unloading port. Multiple horizontal transport wheels are spaced apart along the width of the cargo box, with their axes of rotation parallel to the length of the cargo box. The vertical transport wheels are evenly distributed in the remaining area of ​​the bottom of the cargo box, with their axes of rotation parallel to the width of the cargo box. A mortar inlet is located on the side of the mortar storage bin, and a mortar unloading port extends below the curb stone unloading port. The transport vehicle travels with its length parallel to the road's direction of extension, and the curb stones are placed inside the cargo box with their length parallel to the length of the cargo box.

[0008] Furthermore, the traveling wheel is a steering wheel that integrates a drive motor, a steering motor, and a reducer, and is equipped with a remote control for controlling the movement of the steering wheel.

[0009] Furthermore, the transverse transport wheels are Mecanum wheels, and two rows are arranged side by side along the length of the carriage. The hubs of the two rows of Mecanum wheels correspond one-to-one in the length of the carriage, and the rollers on the corresponding two hubs are symmetrically arranged with the vertical bisector of the line connecting the centers of the two hubs as the axis of symmetry.

[0010] Furthermore, the same row of transverse transport wheels arranged along the length of the carriage are fixed on the same first rotating shaft. The first rotating shaft is rotatably connected to the first support seat at the bottom of the carriage, and the end of the first rotating shaft is provided with a first driven sprocket. The bottom of the carriage is provided with a transverse conveying motor, and its output shaft is provided with a first driving sprocket. The first driving sprocket is connected to all the first driven sprockets through a first chain.

[0011] Furthermore, the vertical transport wheels are rollers with a rubber coating on their surface, and all rollers are arranged in a rectangular array at the bottom of the carriage.

[0012] Furthermore, the same row of vertical transport wheels arranged along the width direction of the carriage are fixed on the same second rotating shaft. The second rotating shaft is rotatably connected to the second support seat at the bottom of the carriage, and the end of the second rotating shaft is provided with a second driven sprocket. The bottom of the carriage is provided with a vertical conveying motor, and its output shaft is provided with a second driving sprocket. The second driving sprocket is connected to all the second driven sprockets through a second chain.

[0013] Furthermore, the mortar storage silo is cylindrical, with a stirring motor installed in the middle. The stirring motor's shaft is equipped with stirring blades, which have an arc-shaped structure, with their outer ends close to the inner wall of the mortar storage silo. When the stirring blades rotate with their concave surfaces facing the mortar discharge port, the mortar gathers towards the middle of the mortar storage silo. When the stirring blades rotate with their convex surfaces facing the mortar discharge port, the mortar is pushed towards the edge of the mortar storage silo and discharged from the mortar discharge port.

[0014] Furthermore, the area at the bottom of the carriage where the transverse transport wheels are arranged is divided into a transfer area and a unloading area. The transverse transport wheels in the two areas operate independently. The unloading area is close to the curbstone unloading port and is equipped with a clamping mechanism above it. The clamping mechanism is set on the lifting mechanism on the inner wall of the carriage. When more than one layer of curbstone enters the unloading area, the clamping mechanism clamps the second layer and above of curbstone and moves upward under the drive of the lifting mechanism, so that the bottommost curbstone can be carried out of the curbstone unloading port by the transverse transport wheels of the unloading area.

[0015] Furthermore, the clamping mechanism includes a fixed clamping plate and a movable clamping plate arranged in parallel. The movable clamping plate is slidably connected to a horizontal sleeve on the fixed clamping plate via a horizontal sliding shaft, and a spring is provided between the horizontal sliding shaft and the fixed clamping plate. The lifting mechanism includes a guide rail arranged vertically on the inner wall of the carriage, a through groove penetrating the side wall of the carriage and parallel to the guide rail, and a fixed pulley arranged on the outer side of the top of the carriage. The fixed clamping plate is restricted to sliding on the guide rail, and a connecting seat passing through the through groove is provided on its side away from the movable clamping plate. A movable pulley is provided on the connecting seat. A pull rope is provided at one end of the horizontal sliding shaft located inside the horizontal sleeve. The pull rope passes through the fixed clamping plate and passes around the movable pulley and the fixed pulley in sequence before being connected to the driver. In its natural state, the movable clamping plate is opened by the spring, so that the movable clamping plate and the fixed clamping plate are respectively located on both sides of the curb stone. When the driver drives the pull rope to move downward, the movable clamping plate and the fixed clamping plate close to clamp the curb stone. Then, the entire clamping mechanism drives the curb stone to move upward along the guide rail.

[0016] Furthermore, the drive is a foot pedal or a lifting motor with a winch, and the pull rope is connected to the foot pedal or wound around the winch; the fixed clamp and the movable clamp are provided with anti-slip rubber pads on opposite sides; the bottom of the carriage is also provided with a storage box, which is located on the same side of the carriage as the unloading area, and the side of the storage box near the middle of the carriage extends beyond the interface between the transfer area and the unloading area; the vertical transport wheels are arranged in the area other than the transfer area, the unloading area and the storage box.

[0017] The beneficial effects of this invention are as follows: By setting a curbstone unloading port on the side of the vehicle traveling in the direction of travel, and configuring a mortar storage bin on the outer side of the bottom of the vehicle and extending the mortar unloading port to below the curbstone unloading port, mortar laying and curbstone placement can be completed simultaneously during vehicle travel, replacing traditional manual handling and lifting operations, significantly reducing labor intensity; the curbstones are placed with their length parallel to the direction of travel of the vehicle, and with the help of vertical and horizontal transport wheels, multiple curbstones can be continuously transferred and the unloading posture can be precisely controlled, allowing the curbstones to be directly placed at the installation point, solving the problems of single-piece, short-distance handling and unloading position deviation of existing tools; a single vehicle can carry multiple curbstones and sufficient mortar, reducing the frequency of round-trip material retrieval, eliminating the phenomenon of "people waiting for materials" and forming a streamlined operation mode, which fits the linear construction characteristics of municipal roads, and can comprehensively improve the paving construction quality and work efficiency while reducing reliance on manual labor.

Detailed Implementation

[0020] The invention will be further described below with reference to the accompanying drawings.

[0021] It should be noted that if this invention uses directional terms such as up, down, left, right, front, and back, these are for describing the relative positions of components and are not specific references to the absolute positions of related components or the relationships between them. They are only used to explain the relative positional relationships and movements of components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. If this invention uses terms related to quantity such as "many," "multiple," or "several," these specifically refer to two or more.

[0022] like Figures 1 to 3 As shown, the present invention provides a transport vehicle for installing curb stones on municipal roads, comprising a carriage 1 and wheels 2. A mortar storage bin 3 is provided on the outer bottom of the carriage 1, and transverse transport wheels 4 and vertical transport wheels 5, driven by a drive mechanism, are provided on the inner bottom of the carriage 1. A curb stone unloading port 11 is located at the bottom corner of a side panel along the length of the carriage 1. The transverse transport wheels 4 are positioned in the area directly opposite the curb stone unloading port 11. Multiple transverse transport wheels 4 are spaced apart along the width of the carriage, with their axis of rotation parallel to the length of the carriage. The vertical transport wheels 5 are evenly distributed in the remaining area of ​​the bottom of the carriage, with their axis of rotation parallel to the width of the carriage. A mortar inlet 31 and a mortar unloading port 32 extending below the curb stone unloading port 11 are provided on the side of the mortar storage bin 3. The transport vehicle travels with its length parallel to the road extension direction, and the curb stones 6 are placed inside the carriage 1 with their length parallel to the length of the carriage 1. The spacing between the horizontal transport wheels 4 and the vertical transport wheels 5 should ensure that each curbstone 6 is in contact with at least four wheels during transportation to prevent the curbstone 6 from tilting. In addition, the curbstone unloading port 11 can extend a section to the side of the truck bed 1 to better align the curbstone installation position.

[0023] The working process of this invention is as follows: First, the curbstone 6 is placed on the vertical transport wheel 5 and the horizontal transport wheel 4 inside the carriage 1 as described above. Mortar is loaded into the mortar storage bin 3 from the mortar inlet 31. Then, the transport vehicle moves along the edge of the road. When the curbstone unloading port 11 on the side of the carriage 1 is aligned with the position where the curbstone 6 needs to be installed, the mortar unloading port 32 is controlled to discharge the mortar first. Then, the horizontal transport wheel 4 is controlled to rotate, driving the curbstone 6 above to move towards the curbstone unloading port 11 and finally fall to the installation position. Finally, the worker only needs to adjust the position of the curbstone 6 appropriately and smooth the mortar at the connection point. After the curbstone installation at one position is completed, the transport vehicle is moved forward to the next position and the above steps are repeated. In this way, the continuous transport and installation of the curbstone 6 can be achieved. After the curb stones 6 on the transverse transport wheel 4 have been transported, the vertical transport wheel 5 can be activated to push the row of curb stones 6 closest to the transverse transport wheel 4 onto the transverse transport wheel 4. This achieves a vertical replenishment and transverse discharge transportation method, ensuring that the unloading posture of the curb stones 6 is consistent with their installation position as the transfer vehicle travels along the road, reducing the adjustment work of the curb stones 6. This transfer vehicle can carry multiple curb stones and sufficient mortar on a single vehicle, reducing the frequency of round-trip material retrieval, thus forming a streamlined operation mode that fits the linear construction characteristics of municipal roads. It can comprehensively improve the paving construction quality and work efficiency while reducing reliance on manual labor.

[0024] The transport vehicle can be moved manually by pushing and pulling. For example, a push rod 14 can be installed at one end near the curbstone unloading port 11 to allow operators to better control the curbstone unloading position when pushing the transport vehicle. Of course, if a large number of curbstones are loaded, manual pushing and pulling will be difficult. Therefore, the preferred solution is that the traveling wheels 2 are steering wheels that integrate a drive motor, a steering motor, and a reducer, and are equipped with a remote control for controlling the movement of the steering wheels. Currently, there are various steering wheels on the market, and the appropriate one can be selected according to the actual load capacity. Using a remote control to control the operation of the transport vehicle can better adjust the position of the curbstone unloading port 11 and ensure the installation accuracy of the curbstones 6. Of course, to realize the operation of the horizontal transport wheels 4, the vertical transport wheels 5, and the traveling wheels 2, batteries and corresponding control systems are essential. The battery is not shown in the diagram and can be installed inside the carriage 1 or at both ends of the carriage 1. The control system uses conventional single-chip microcomputers and remote control technology. The control logic is relatively simple. It is only necessary to integrate the function of controlling the start and stop of the horizontal transport wheels 4 and the vertical transport wheels 5 into the remote control of the steering wheels.

[0025] For the horizontal transport wheel 4 and the vertical transport wheel 5, the preferred embodiment of the present invention is: like Figure 1 , Figure 4As shown, the transverse transport wheels 4 are Mecanum wheels, arranged in two rows side-by-side along the length of the carriage 1. The hubs of the two rows of Mecanum wheels correspond one-to-one along the length of the carriage, and the rollers on the corresponding two hubs are symmetrically arranged with the perpendicular bisector of the line connecting the centers of the two hubs as the axis of symmetry. The use of Mecanum wheels as transverse transport wheels 4 primarily utilizes their rollers to reduce the resistance of the vertical transport wheels 5 pushing the curbstone 6 onto the transverse transport wheels 4. The symmetrical arrangement of the rollers on the two rows of Mecanum wheels ensures that when the two rows of Mecanum wheels rotate in the same direction, the resultant force of the frictional force on the curbstone 6 is in the direction of the carriage width. The drive mechanism that drives all the transverse transport wheels 4 synchronously is as follows: Figure 4 As shown, the same row of transverse transport wheels 4 arranged along the length of the carriage 1 are fixed on the same first rotating shaft 41. The first rotating shaft 41 is rotatably connected to the first support seat 42 at the bottom of the carriage 1, and the end of the first rotating shaft 41 is provided with a first driven sprocket 43. The bottom of the carriage 1 is provided with a transverse conveying motor 44, and its output shaft is provided with a first driving sprocket 45. The first driving sprocket 45 is connected to all the first driven sprockets 43 through a first chain 46. Of course, in addition to using sprocket and chain transmission, pulley and belt or gear transmission can also be used. The start and stop of the transverse transport wheels 4 can be controlled by the control button or remote control on the carriage 1. The operator controls the operation of the transverse transport wheels 4 by observing the position of the roadside stone 6 in the carriage 1 and whether unloading has occurred.

[0026] like Figure 1 , Figure 5 As shown, the vertical transport wheels 5 are rollers with a rubber layer on their surface, and all rollers are arranged in a rectangular array at the bottom of the carriage 1. The rubber layer serves to cushion and increase friction, preventing damage to the curb stones 6 during placement and transportation, while ensuring that the vertical transport wheels 5 can generate sufficient thrust on the curb stones 6 to push them onto the horizontal transport wheels 4. The drive mechanism that drives all the vertical transport wheels 5 to operate synchronously is as follows: Figure 5 As shown, the same row of vertical transport wheels 5 arranged along the width direction of the carriage 1 are fixed on the same second rotating shaft 51. The second rotating shaft 51 is rotatably connected to the second support seat 52 at the bottom of the carriage 1, and the end of the second rotating shaft 51 is provided with a second driven sprocket 53. The bottom of the carriage 1 is provided with a vertical conveying motor 54, and its output shaft is provided with a second driving sprocket 55. The second driving sprocket 55 is connected to all the second driven sprockets 53 through a second chain 56. Of course, in addition to using sprocket and chain drive, pulley and belt or gear drive can also be used. Similarly, the start and stop of the vertical transport wheels 5 are also controlled by the control button or remote control on the carriage 1. The operator controls the operation of the vertical transport wheels 5 by observing the position of the curb stones 6 in the carriage 1 and whether there are still curb stones 6 on the horizontal transport wheels 4, and replenishes the curb stones 6 on the horizontal transport wheels 4.

[0027] For the mortar storage silo 3, the preferred embodiment of the present invention is as follows: Figure 6 As shown, the mortar storage silo 3 is cylindrical, with a stirring motor 33 located in its center. A stirring blade 34 is mounted on the shaft of the stirring motor 33. The stirring blade 34 has an arc-shaped structure, with its outer end close to the inner wall of the mortar storage silo 3. When mortar is not being discharged, the stirring blade 34 rotates with its concave surface facing the mortar discharge port 32. At this time, the mortar will collect along the concave surface towards the center of the mortar storage silo 3. Simultaneously, the bottom of the mortar discharge port 32 has an upward-sloping structure, ensuring that the mortar will not be discharged from the mortar discharge port 32, while also stirring the mortar to prevent localized solidification. When mortar discharge is required, the stirring blade 34 rotates with its convex surface facing the mortar discharge port 32. At this time, the mortar will move along the convex surface towards the edge of the mortar storage silo 3. Upon reaching the mortar discharge port 32, it will be squeezed out by centrifugal force, achieving mortar discharge. After discharge, the stirring blade 34 is then controlled to rotate in the other direction. The forward and reverse rotation of the mixing motor 33 is controlled by the control button or remote control on the carriage 1. The operator controls the forward and reverse rotation of the mixing motor 33 by observing the amount of mortar discharged.

[0028] To achieve single-piece unloading of the curbstone 6, the above conveying methods are all carried out when there is only one layer of curbstone in the carriage 1. However, in order to reduce the frequency of the transfer vehicle reloading the curbstone 6, it is best to load multiple layers of curbstone 6 into the carriage 1 at one time. The problem with this is that it is difficult to achieve single-piece unloading of the curbstone 6. To solve this technical problem, the present invention provides an improved solution. For example... Figures 1 to 3 As shown, the area at the bottom of the carriage 1 where the transverse transport wheels 4 are arranged is divided into a transfer area 12 and a discharge area 13. The transverse transport wheels 4 in the two areas operate independently. The discharge area 13 is close to the curbstone discharge port 11, and a clamping mechanism 7 is provided above it. The clamping mechanism 7 is set on the lifting mechanism 8 on the inner wall of the carriage 1. When more than one layer of curbstone 6 enters the discharge area 13, the clamping mechanism 7 clamps the second and above layers of curbstone 6 and moves upward under the action of the lifting mechanism 8, so that the bottommost curbstone 6 can be carried out of the curbstone discharge port 11 by the transverse transport wheels 4 of the discharge area 13. After the curbstone 6 in the discharge area 13 is completely discharged, the transverse transport wheels 4 in the transfer area 12 are controlled to replenish the discharge area 13. The combination of clamping mechanism 7 and lifting mechanism 8 can realize the orderly unloading of multi-layer stones. If the size of the side stone unloading port 11 is only set to match the size of a single roadside stone 6 for unloading, on the one hand, the friction between the upper roadside stone 6 and the lower roadside stone 6 may hinder the movement of the lower roadside stone 6, affecting the smoothness of unloading. On the other hand, after the lower roadside stone 6 is pushed out, the upper roadside stone 6 is at risk of rolling and tipping over. The solution of the present invention can effectively solve the above technical difficulties.

[0029] For the clamping mechanism 7 and the lifting mechanism 8, the present invention provides an embodiment, such as... Figures 1 to 3 As shown, the clamping mechanism 7 includes a fixed clamping plate 71 and a movable clamping plate 72 arranged side by side. The movable clamping plate 72 is slidably connected to a horizontal sleeve 74 on the fixed clamping plate 71 via a horizontal sliding shaft 73, and a spring 75 is provided between the horizontal sliding shaft 73 and the fixed clamping plate 71. The lifting mechanism 8 includes a guide rail 81 arranged vertically on the inner wall of the carriage 1, a through groove 82 penetrating the side wall of the carriage 1 and parallel to the guide rail 81, and a fixed pulley 83 arranged on the outer side of the top of the carriage 1. The fixed clamping plate 71 is restricted to sliding on the guide rail 81, and a connecting seat 76 passing through the through groove 82 is provided on the side away from the movable clamping plate 72. A movable pulley 84 is provided on the connecting seat 76. A pull rope 85 is provided at one end of the horizontal sliding shaft 73 located inside the horizontal sleeve 74. The pull rope 85 passes through the fixed clamping plate 71 and passes around the movable pulley 84 and the fixed pulley 83 in sequence before being connected to the drive unit. In its natural state, the movable clamping plate 72 is supported by the spring 75, placing the movable clamping plate 72 and the fixed clamping plate 71 on opposite sides of the curbstone 6. When the driver moves the pull rope 85 downwards, the pull rope 85, due to the weight of the clamping mechanism 7 itself, will first move the movable clamping plate 72 towards the fixed clamping plate 71 to clamp the curbstone 6. Simultaneously, the spring 75 is compressed. When the pull rope 85 continues to pull downwards, the movable clamping plate 72 can no longer move. The pull rope 85 then moves the entire clamping mechanism 7 and the clamped curbstone 6 upwards along the guide rail 81. After the upper curbstone 6 is lifted and detached from the lower curbstone 6, the lower curbstone 6 can be pushed out of the curbstone discharge port 11 by the transverse transport wheel 4 in the unloading area 13. Then, the pull rope 85 is released, and the curbstone 6 falls onto the transverse transport wheel 4 under gravity. This cycle can achieve the unloading of multiple layers of curbstone 6. Figure 3 Only the clamping mechanism 7 applicable to two layers of curb stones 6 is shown. By raising the fixed clamping plate 71 and the movable clamping plate 72, and by placing the horizontal sliding shaft 73 and the horizontal sleeve 74 on their sides, the clamping of multiple layers of curb stones 6 can be achieved. The start-up of the clamping mechanism 7 and the lifting mechanism 8 can be synchronously controlled with the start and stop of the transverse transport wheels 4 in the unloading area 13. That is, after the unloading switch is pressed, the lifting mechanism 8... For the driver, this invention provides two solutions, one of which is as follows: Figure 3As shown, the actuator is a foot pedal 86, with a pull rope 85 connected to it. When unloading is required, the operator first steps on the foot pedal 86, the clamping mechanism 7 clamps the curbstone 6, and then the transverse conveyor wheel 4 in the unloading area 13 is activated to push the curbstone 6 out. Afterwards, the transverse conveyor wheel 4 is turned off and the foot pedal 86 is released. Alternatively, the foot pedal 86 can be linked to the start / stop switch of the transverse conveyor wheel 4; the transverse conveyor wheel 4 starts simultaneously with or after a certain delay when the foot pedal 86 is pressed. This type of actuator is suitable for situations where the curbstone 6 is small or not very heavy. As long as stepping on the foot pedal 86 reduces friction on the lower curbstone 6, ensuring it can be pushed out smoothly, it is sufficient; a high lifting height is not necessary. However, for situations where the curbstone 6 is heavy or has many layers, and stepping on the foot pedal 86 is insufficient to lift the upper curbstone 6, another preferred solution can be used, such as... Figure 7 As shown, the driver is a lifting motor 87 with a winch. The pull rope 85 is connected to the foot pedal 86 or wound around the winch. For easy control, the switch of the lifting motor 87 can also be associated with the start / stop switch of the transverse transport wheel 4 to realize the synchronous or sequential lifting and unloading.

[0030] In addition, to ensure that the clamping mechanism 7 can stably clamp the curbstone 6, anti-slip pads 77 can be installed on the opposite side of the fixed clamping plate 71 and the movable clamping plate 72. Considering that tools such as shovels and pry bars are also needed during the installation of the curbstone 6, a storage box 9 can also be installed at the bottom of the carriage 1. The storage box 9 and the unloading area 13 are located on the same side of the carriage 1, and the side of the storage box 9 near the middle of the carriage 1 extends beyond the interface between the transfer area 12 and the unloading area 13. The vertical transport wheel 5 is arranged in the area other than the transfer area 12, the unloading area 13 and the storage box 9. In this way, when the curbstone 6 on the vertical transport wheel 5 moves to the horizontal transport wheel 4, the curbstone 6 will only enter the transfer area 12 and will not enter the unloading area 13 to interfere with the clamping mechanism 7. At the same time, it is ensured that the curbstone 6 must pass through the clamping mechanism 7 before unloading, ensuring the orderly unloading of multiple layers of stones.
