Description

TECHNICAL FIELD

[0001] The present application relates to the paving machine technical field, specifically to a paving and compaction synchronous linkage type automatic sand gravel paving machine. BACKGROUND

[0002] Sand gravel paving is a key basic process in road, water conservancy, building foundation and other engineering, and the core is to evenly and flatly lay graded sand gravel (mixed by sand and gravel of different particle sizes according to the proportion) on the surface of the base or foundation to form a structure layer meeting the requirements of strength, water permeability or bearing capacity, and the construction quality directly affects the stability of the subsequent engineering (such as road surface pouring and impermeable layer laying), which needs to strictly follow the whole process specification of material control, paving preparation, on-site construction and quality inspection.

[0003] At present, in the sand gravel paving operation of the existing equipment, most of the equipment relies on single screw conveying or scraper conveying structure, which is difficult to deal with mixed materials of different particle sizes of sand gravel, and is prone to problems of excessive thickness of material accumulation in the center area and excessive thinness of material in the edge area, so that the paving uniformity is insufficient; and the traditional equipment needs to complete the paving operation first, and then compaction is carried out by a separate road roller, which increases the equipment investment and construction period; at the same time, the adjustment of the ground clearance of the paving assembly of the existing equipment is mostly carried out by manual mechanical adjustment mode, which is complicated to operate and difficult to accurately adapt to different thickness construction requirements, and the adjustment efficiency and accuracy are low; in addition, a large amount of dust is easily generated in the conveying, paving and compaction process of sand gravel, and the existing equipment is generally not equipped with effective dust reduction device, which may cause the dust concentration of the construction environment to exceed the standard, which not only harms the health of the operators, but also pollutes the surrounding environment.

[0007] In a further embodiment, the walking mechanism is provided in two sets, and the two sets of the walking mechanism are located at both ends of the frame, and the walking mechanism enables the machine body to move.

[0008] In a further embodiment, two sets of sliding columns are provided, and the two sets of sliding columns are located at both ends of the movable frame, making the base frame move more stably.

[0009] In a further embodiment, the first transmission component includes two transmission pulleys and a transmission belt outside both of them.

[0010] In a further embodiment, a compaction assembly is provided on the base frame. The compaction assembly includes a limiting rod, which is slidably mounted on the base frame.

[0011] In a further embodiment, two sets of limiting rods and springs are provided, and the two sets of limiting rods and springs are located at both ends of the compaction plate for better buffering.

[0012] In a further embodiment, a second motor and a second bearing seat are also fixedly installed on the base frame.

[0016] Compared with the prior art, the present invention provides an automatic gravel paver with simultaneous paving and compaction, which has the following beneficial effects: 1. This automatic gravel paver with synchronous paving and compaction improves paving efficiency. Firstly, the machine's movement is achieved through the traveling mechanisms at both ends of the frame, which, in conjunction with the material conveying mechanism, transports the gravel. By incorporating paving components, starting the asynchronous motor on the support causes the threaded rod to rotate, which in turn causes the threaded block to slide the moving frame on the frame. Starting the first winding machine, along with the sliding column, the first telescopic rope, and the first limit wheel, allows the base frame to move up and down, adjusting the ground clearance for agitation and compaction. Starting the first motor, in conjunction with the transmission component, causes the auger paddle to rotate inside the first bearing seat, thus conveying and spreading the centrally accumulated gravel to both sides, avoiding the problem of excessively thick or thin areas in traditional paving, thereby improving the paving effect.

[0017] 2. This automatic gravel paver with synchronous paving and compaction is equipped with a compaction component to improve the paving effect. When the vibrating motor on the compaction plate is started, the limit rod can slide on the base frame, causing the spring to deform. This allows the compaction plate to move up and down to compact the gravel below, which has been agitated by the auger paddle. When the second motor is started, the second transmission component causes the compaction roller to rotate inside the second bearing seat. This allows the compaction roller to further compact and level the already compacted material, resulting in a better paving effect.

[0018] 3. This automatic gravel paver with synchronous paving and compaction features auxiliary components to improve its practicality. When the second winding machine is started, in conjunction with the second telescopic rope and the second limit switch, the sliding frame can slide on the machine frame. When the water pump is started, water is injected into the multi-head pipe and the outlet pipe, and then sprayed out through the nozzles to reduce dust on the gravel conveying mechanism. This effectively avoids dust generation during the conveying and paving compaction process, thereby improving the machine's practicality. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0023] Please see Figures 1-11 The present invention provides a technical solution: An automatic gravel paver with synchronous paving and compaction includes a frame 1, with walking mechanisms 2 at both ends of the frame 1. The walking mechanisms 2 are provided in two sets, and the two sets of walking mechanisms 2 are located at both ends of the frame 1. The walking mechanisms 2 enable the machine body to move. A material conveying mechanism 3 is provided on the frame 1 for conveying gravel materials.

[0024] Specifically, the traveling mechanism 2 is started first. As the power actuator for the movement of the whole machine, the traveling mechanism 2 drives the frame 1 to move smoothly along the preset working path through its own drive unit (such as a motor and transmission gear set). The moving speed can be adjusted according to the required thickness of the gravel paving, so that the whole machine always maintains a moving state that matches the material conveying rhythm. At the same time, the material conveying mechanism 3 is started. The material conveying mechanism 3 consists of a conveyor belt, a drive roller and a tensioning component. After starting, the conveyor belt runs at a uniform speed, continuously conveying the gravel material to be paved from the material stacking point to the working area below the frame 1. This provides a continuous and stable material supply for the subsequent paving component 4 and compaction component 5, avoiding the occurrence of discontinuity in the working surface due to material interruption.

[0025] In one embodiment of the present invention, a paving assembly 4 is further provided on the frame 1. The paving assembly 4 includes a support 41, which is fixedly installed on the frame 1. An asynchronous motor 42 is fixedly installed on the support 41. A threaded rod 43 is rotatably installed on the support 41 via bearing components. The threaded rod 43 is fixedly connected to the output end of the asynchronous motor 42. A threaded block 44 is threadedly fitted on the threaded rod 43. A movable frame 45 is fixedly installed on the outside of the threaded block 44. The movable frame 45 is rotatably installed on the frame 1 via rollers. A sliding column 46 is slidably installed inside the movable frame 45. A base frame 47 is fixedly installed at the bottom of the sliding column 46. In addition, two sets of sliding columns 46 are provided, and the two sets of sliding columns 46 are located at both ends of the movable frame 45, so that the base frame 47 moves more stably. A first winding machine 48 is fixedly installed on a movable frame 45. A first limiting wheel 410 is rotatably installed on a base frame 47 via bearing components. A first telescopic rope 49 is provided between the first winding machine 48 and the first limiting wheel 410. The end of the first telescopic rope 49 away from the first winding machine 48 is fixedly installed on the movable frame 45. A first motor 411 is fixedly installed on the base frame 47. A first bearing seat 412 is fixedly installed on the base frame 47. Two sets of first bearing seats 412 are provided. An auger paddle 413 is rotatably installed between the two sets of first bearing seats 412. A first transmission component 414 is installed between the auger paddle 413 and the output end of the first motor 411. In addition, the first transmission component 414 includes two transmission pulleys and a transmission belt outside the two pulleys.

[0026] In this embodiment, when in use, the asynchronous motor 42 in the paving assembly 4 is started. After the asynchronous motor 42 is powered on, it outputs torque, which directly drives the threaded rod 43 to rotate around its own axis through the coupling (the two ends of the threaded rod 43 are rotatably connected to the bracket 41 through bearings, which can reduce the frictional resistance when the threaded rod 43 rotates). Since the threaded rod 43 and the threaded block 44 are threadedly mated, the rotation of the threaded rod 43 is converted into the linear motion of the threaded block 44, which in turn drives the movable frame 45, which is welded and fixed to the threaded block 44, to move along the guide rail on the frame 1 (the guide rail is pre-installed). Installed on the top of the frame 1 and adapted to the rollers at the bottom of the mobile frame 45, the mobile frame 45 can slide. The operator can adjust the horizontal position of the mobile frame 45 on the frame 1 by controlling the forward and reverse rotation of the asynchronous motor 42, so that the working range of the subsequent auger paddle 413 can completely cover the material conveying area of ​​the material conveying mechanism 3, avoiding the occurrence of paving blind spots. After the horizontal position is adjusted, the first winding machine 48 is started (the first winding machine 48 has forward and reverse winding and unwinding functions). If it is necessary to lower the height of the base frame 47 to reduce the paving thickness, the first winding machine 48 rotates in the forward direction to release the first telescopic rope 49.If it is necessary to raise the height of the base frame 47 to increase the paving thickness, the first winding machine 48 reverses its rotation to wind up the first telescopic rope 49. One end of the first telescopic rope 49 is fixedly connected to the drum of the first winding machine 48, and the other end passes around the first limiting wheel 410 installed on the side of the base frame 47 (the first limiting wheel 410 is rotatably connected to the base frame 47 through a bearing, which can change the direction of force on the first telescopic rope 49 and avoid the rope from directly rubbing against the base frame 47 and causing wear). Finally, it is fixedly connected to the hook at the bottom of the movable frame 45. At the same time, the sliding column 46 moves along the movable frame. The sliding sleeve of 45 slides up and down, guiding the movement of the base frame 47 and preventing it from deviating during its up-and-down movement. Through the winding and unwinding action of the first winding machine 48 and the guiding action of the sliding column 46, the base frame 47 drives the auger propeller 413 installed at its bottom to adjust its height off the ground, adapting to the gravel paving thickness requirements of different engineering scenarios. After the height and position are adjusted, the first motor 411 is started. The torque output by the first motor 411 is transmitted to the auger propeller 413 through the first transmission component 414 (the first transmission component 414...). 14 consists of two matching drive pulleys and an annular drive belt. One drive pulley is keyed to the output shaft of the first motor 411, and the other drive pulley is keyed to one end of the auger propeller 413. The drive belt is sleeved on the outside of the two drive pulleys to achieve stable power transmission. The two ends of the auger propeller 413 are rotatably connected to two sets of first bearing seats 412 via bearing components. (The first bearing seats 412 are fixedly installed at the bottom of the base frame 47 by bolts. The two sets of first bearing seats 412 are symmetrically distributed to ensure the stability of the auger propeller 413 during rotation.) (Coaxiality), driven by the first motor 411, the auger propeller 413 rotates uniformly around its own axis. When the gravel conveyed by the conveying mechanism 3 accumulates below the auger propeller 413, the spiral blades of the auger propeller 413 will push the gravel accumulated in the central area evenly to both sides, so that the gravel forms a uniformly thick layer on the working surface. This effectively avoids the problems of uneven material accumulation in traditional manual paving or single-spiral paving, which can lead to localized excessive thickness (easily causing substandard subsequent compaction) or excessive thinness (easily causing voids), significantly improving the uniformity of paving.

[0027] In one embodiment of the present invention, a compaction assembly 5 is provided on the base frame 47. The compaction assembly 5 includes a limiting rod 51, which is slidably mounted on the base frame 47. A compaction plate 52 is fixedly mounted on the bottom of the limiting rod 51. A spring 53 is provided between the base frame 47 and the compaction plate 52. The spring 53 is sleeved on the outside of the limiting rod 51. A vibration motor 54 is provided at the top center of the compaction plate 52. In addition, two sets of limiting rods 51 and springs 53 are provided, and the two sets of limiting rods 51 and springs 53 are located at both ends of the compaction plate 52. To better buffer the impact, a second motor 55 and a second bearing seat 56 are fixedly installed on the base frame 47. Two sets of second bearing seats 56 are provided, and a compaction roller 57 is rotatably installed between the two sets of second bearing seats 56. A second transmission component 58 is installed between the output end of the compaction roller 57 and the second motor 55. The second transmission component 58 includes two transmission pulleys and a transmission belt outside the two. In addition, the compaction plate 52 is located between the auger paddle 413 and the compaction roller 57, thereby better agitating, compacting and leveling.

[0028] In this embodiment, the vibration motor 54 in the compaction assembly 5 is started (the vibration motor 54 is fixedly installed at the center of the top of the compaction plate 52 by bolts; the vibration frequency can be adjusted according to the particle size of the gravel; when the particle size is large, the vibration frequency needs to be increased to ensure the compaction effect). The vibration motor 54 generates high-frequency vibration when it runs, which is directly transmitted to the compaction plate 52 (the compaction plate 52 is a steel plate with a flat bottom and the contact surface with the gravel is treated with wear resistance). Because the limiting rod 51 welded and fixed to the top of the compaction plate 52 runs along the limiting hole of the base frame 47... As the compaction plate slides downwards, the vibration of the vibrating motor 54 drives the compaction plate 52 to move up and down along the axis of the limiting rod 51. Simultaneously, the spring 53, sleeved outside the limiting rod 51, undergoes compression or stretching deformation as the compaction plate 52 moves. The elastic restoring force of the spring 53 buffers the impact between the compaction plate 52 and the base frame 47, preventing damage to parts from rigid collisions. During this process, the compaction plate 52 applies high-frequency vibration pressure to the gravel layer laid by the auger propeller 413, reducing the gaps between the gravel particles and achieving initial compaction. This initial compaction lays the foundation for subsequent secondary leveling. After the initial compaction is completed, the second motor 55 is started. The torque output by the second motor 55 is transmitted to the compaction roller 57 through the second transmission component 58 (the structure of the second transmission component 58 is the same as that of the first transmission component 414, consisting of two transmission pulleys and a transmission belt to ensure the stability of power transmission). The two ends of the compaction roller 57 are rotatably connected to two sets of second bearing seats 56 through bearing components (the second bearing seats 56 are fixedly installed at the bottom of the base frame 47 by bolts, located behind the compaction plate 52, and the two sets of second bearings...). The seats 56 are symmetrically distributed to ensure the stability of the compaction roller 57 during rotation. Driven by the second motor 55, the compaction roller 57 rotates at a constant speed around its own axis. When the initially compacted gravel layer moves to the bottom of the compaction roller 57, the compaction roller 57, under the action of its own weight and rotational friction, rolls and flattens the gravel layer, flattening any small protrusions that may exist after the initial compaction, while further reducing the gaps between gravel particles, improving the density and surface flatness of the gravel layer, and ensuring that the final working surface meets the engineering quality standards.

[0029] In one embodiment of the present invention, an auxiliary component 6 is further provided on the frame 1. The auxiliary component 6 includes a second winding machine 61, which is fixedly installed on the frame 1. Second limit wheels 63 are rotatably installed at both ends of the frame 1 via bearing components. A second telescopic rope 62 is provided between the second winding machine 61 and the second limit wheels 63. A sliding frame 64 is fixedly installed on the second telescopic rope 62. The sliding frame 64 is rotatably installed on the frame 1 via rollers. The sliding frame 64 is located above the material conveying mechanism 3. In addition, a water pump 65 is fixedly installed on the sliding frame 64. A multi-head pipe 66 is fixedly installed at the output end of the water pump 65. A water outlet pipe 67 is fixedly installed at the output end of the multi-head pipe 66. A nozzle 68 is provided at the output end of the water outlet pipe 67. Multiple sets of water outlet pipes 67 and nozzles 68 are provided to improve the dust suppression effect.

[0030] In this embodiment, the second winding machine 61 in the auxiliary component 6 is started (the second winding machine 61 has a precise winding and unwinding control function). The second winding machine 61 operates to wind the second telescopic rope 62, driving the sliding frame 64 to move. One end of the second telescopic rope 62 is fixedly connected to the drum of the second winding machine 61, and the other end passes around the second limit wheels 63 installed at both ends of the frame 1 (the second limit wheels 63 are rotatably connected to the frame 1 through bearing components, which can change the force direction of the second telescopic rope 62 and ensure that the sliding frame 64 moves). (with uniform force distribution), and finally fixedly connected to the side of the sliding frame 64. The bottom of the sliding frame 64 is equipped with rollers that are compatible with the guide rails on the top of the frame 1 (which are the same specifications as the guide rails used in the moving frame 45). It can slide smoothly along the guide rails, and the sliding frame 64 is always located above the conveying mechanism 3 to ensure that the subsequent dust suppression operation can directly act on the sand and gravel conveyed by the conveying mechanism 3. Start the water pump 65 (the water pump 65 is fixedly installed on the top of the sliding frame 64 with bolts, and the water inlet is connected to an external water source through a pipe). After operation, external water is pressurized and drawn in, and transported to the multi-head pipe 66 (the multi-head pipe 66 is a multi-port pipe, fixed to the bottom of the sliding frame 64 by pipe clamps, and the water inlet end is connected to the output end of the water pump 65 through a flange to ensure a leak-proof seal). The water is split within the multi-head pipe 66 and enters multiple sets of water outlet pipes 67. Finally, it is atomized and sprayed out through the nozzle 68 (the nozzle 68 has a diversion core and atomizing plate inside, which can convert the water into fine water mist particles to ensure that the water mist can effectively cover the dusty area). The sprayed water mist will come into contact with the surface of the gravel conveyed on the conveying mechanism 3, increasing the humidity of the gravel particles and preventing dust from being generated by collision during the conveying process. At the same time, the water mist will spread to the working area of ​​the paving component 4 and the compaction component 5, capturing the dust particles raised during the operation and causing the dust particles to settle with the water mist, effectively reducing the dust concentration in the working environment, avoiding the impact of dust on the health of operators, and preventing dust pollution of the surrounding environment, significantly improving the practicality and environmental friendliness of the machine.
