Description

Technical Field

[0001] This utility model relates to a paver track material blocking device and a paver, belonging to the field of road construction machinery. Background Technology

[0002] Asphalt pavers are the core equipment for the construction of asphalt concrete road surface and base layers, and their operational stability directly determines the construction quality and service life of road projects. With the continuous improvement of road construction requirements for efficiency, automation, and paving precision, the intelligentization and functional adaptability upgrades of pavers have become an industry trend. Users have raised higher standards for the practicality and reliability of tracked system components, and the performance optimization of tracked material retaining devices, as key components ensuring construction continuity and road surface smoothness, is particularly urgent.

[0003] In actual construction scenarios, dump trucks need to precisely pour the paving material into the hopper at the front of the paver. However, throughout the entire process of the dump truck lifting and unloading, hopper receiving, or vehicle removal, factors such as material flowability, unloading angle deviation, and equipment vibration can cause some of the paving material to spill onto the area in front of the paver's tracks. If this spilled material is not cleaned up in time, it will be crushed and embedded in the paving layer as the tracks rotate, or it may cause uneven track stress and deviation of the travel trajectory. This not only damages the uniformity of the asphalt concrete paving but may also cause quality defects such as unevenness and scratches on the road surface, seriously affecting the final paving smoothness and increasing rework costs and maintenance workload later on. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a paver track material blocking device and a paver, avoiding the problem of reduced paving smoothness caused by obstruction of paving material or foreign objects.

[0005] To achieve the above objectives, this utility model employs a paver track material blocking device, comprising a mounting bracket, a pusher plate assembly, a rubber plate, a pressure plate, a limiting plate, and a rotating shaft; the mounting bracket is detachably mounted on the paver frame, the pusher plate assembly is rotatably connected to the mounting bracket via the rotating shaft, the rubber plate is mounted on the working side of the pusher plate assembly via the pressure plate, and the limiting plate is mounted on the mounting bracket via bolts and limiting blocks to limit the rotation angle of the pusher plate assembly.

[0006] As an improvement, the paver track material blocking device is configured in two sets, symmetrically arranged on both sides of the front of the paver body, and the left and right sets of material blocking devices are independently controlled and adjusted.

[0007] As an improvement, the pusher plate assembly includes a pusher plate body and a bushing two fixed to one end of the pusher plate body. The mounting bracket includes a bracket body, and the bracket body is provided with a bushing one that cooperates with the bushing two. The rotating shaft passes through the bushing two and the bushing one, so that the pusher plate body can rotate around the bracket body of the mounting bracket.

[0008] As an improvement, the main body of the support is a triangular structure formed by splicing or integrally molding three plates.

[0009] As an improvement, two limiting teeth are symmetrically installed on the side of the pusher plate body, and slots are opened on the support body corresponding to the movement trajectory of the limiting teeth for their movement; when the pusher plate body rotates along the rotation axis, the two limiting teeth rotate synchronously in the slots to realize the up and down angle swing of the pusher plate body. The lower end of the limiting plate is engaged with the limiting teeth to limit the rotation angle of the pusher plate assembly.

[0010] As an improvement, the limiting tooth is provided with no less than two limiting slots for the lower end of the limiting plate to engage, so as to realize multi-position adjustment of the pusher plate assembly.

[0011] As an improvement, the rubber sheet is attached and fixed to the side of the pusher plate assembly facing the track, and the working end face of the rubber sheet protrudes from the edge of the pusher plate assembly.

[0012] As an improvement, both the limiting plate and the rubber plate are provided with multiple adjustment holes, which are oblong holes.

[0013] As an improvement, the limiting plate is fixed to the mounting bracket after passing through the adjustment hole with the limiting bolt; the rubber plate is fixed to the pusher plate body of the pusher plate assembly after passing through the adjustment hole with the clamping bolt.

[0014] In a second aspect, this utility model also provides a paver, which is a rubber track paver, and the paver is equipped with the aforementioned paver track material blocking device.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. Compact structure and flexible assembly: The detachable design of the mounting bracket allows for quick assembly and disassembly of the material blocking device and the paver frame. This not only facilitates daily equipment maintenance and component replacement but also adapts to the frame installation requirements of different paver models, making it highly versatile. The connections between the core components (push plate assembly, rubber plate, limit plate, etc.) are clear, resulting in a simple and compact overall structure that occupies little space on the paver body and does not affect the normal operation of other working components.

[0016] 2. Precise and controllable material blocking effect: The pusher plate assembly is rotatably connected to the mounting bracket via a rotating shaft. With the help of the limiting plate, the rotation angle is precisely limited. The working angle and height of the pusher plate can be flexibly adjusted according to the thickness of the layer to be paved and the characteristics of the paving material, ensuring the guiding and blocking effect on the spilled paving material. The rubber plate on the working side can fit tightly against the side of the track, effectively filling the gap and preventing the paving material from leaking from the gap, completely solving the problem of reduced paving smoothness caused by material accumulation and leakage at the front of the track in traditional construction.

[0017] 3. Stable operation and excellent protection: As a component that directly contacts the paving material, the rubber plate is soft and wear-resistant, which can enhance the sealing of the material blocking and avoid rigid collisions with the track or paving material, reduce component wear and construction noise, and extend the overall service life of the device; the limiting plate achieves the limiting through the cooperation of bolts and limiting blocks, and the connection is firm and reliable. It can maintain the limiting accuracy under the vibration operation of the paver, ensuring that the pusher plate assembly will not deviate from the preset working position due to vibration, thus ensuring construction stability.

[0018] 4. Easy to operate and widely adaptable: No complex control mechanism is required. The working angle can be adjusted simply by rotating the pusher plate assembly. Combined with the limiting plate for limiting and fixing, the operation steps are simple and easy to understand, reducing the labor intensity of operators. The detachable installation and modular design allow for individual replacement of damaged parts without the need for overall disassembly, resulting in low maintenance costs. It is also suitable for construction scenarios of different types of paving materials such as asphalt concrete and stabilized soil, making it highly practical. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this application will be described in detail below through specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1-4 As shown, a paver track material blocking device includes a mounting bracket 1, a pusher plate assembly 2, a rubber plate 3, a pressure plate 4, a limiting plate 5, a limiting block 6, and a rotating shaft 7. The mounting bracket 1 adopts a detachable structure and is assembled onto the paver frame. This not only enables quick assembly and disassembly of the device and the frame, but also flexibly adapts to the installation requirements of different paver models. It also facilitates later maintenance, repair, and individual component replacement, significantly reducing maintenance costs. The pusher plate assembly 2 forms a flexibly rotatable connection structure with the mounting bracket 1 via the rotating shaft 7. It can adjust the working angle as needed according to the thickness of the layer to be paved and the characteristics of the paving material. Combined with the bolt-fastening limit design of the limiting plate 5 and the limiting block 6, the rotation angle of the pusher plate assembly 2 can be locked, ensuring that the device always maintains the preset working position during construction, effectively avoiding positional deviation caused by paver vibration. The rubber plate 3 is tightly fitted and fixed to the working side of the pusher plate assembly 2 via the pressure plate 4. On the one hand, it fills the gap between the pusher plate assembly 2 and the track, improving the sealing performance of the material and completely preventing paving material leakage and spillage. On the other hand, the flexible properties of the rubber material reduce rigid collision and friction with the track and paving material, reducing construction noise and slowing down component wear, significantly extending the overall service life of the device.

[0024] In some embodiments, such as Figure 5 , Figure 6 As shown, the paver track material blocking device is configured in two sets, symmetrically arranged on both sides of the front of the paver body along the longitudinal center line of the paver body. The left and right sets of material blocking devices support independent control and angle and height adjustment, which can be flexibly adapted according to the paving material spillage in the track area on both sides, further improving the material blocking targeting and the overall paving flatness.

[0025] In some embodiments, such as Figure 2 As shown, the pusher plate assembly 2 includes a pusher plate body and a bushing 2-2 fixed to one end of the pusher plate body; the mounting bracket 1 includes a bracket body 1-1, and a coaxially adapted bushing 1-4 is provided on the bracket body 1-1 at a position corresponding to bushing 2-2; the rotating shaft 7 passes through the inner holes of bushing 2-2 and bushing 1-4, forming a precise and stable rotational fit structure. The rigid fit between the bushing and the rotating shaft improves the connection strength, which can withstand the vibration conditions during paver construction, and allows the pusher plate body to rotate flexibly and smoothly around the bracket body 1-1. This provides reliable structural support for subsequent adjustment of the working angle as needed, ensuring a smooth and uninterrupted angle adjustment process and improving operational convenience.

[0026] In some embodiments, such as Figure 2 As shown, the main body 1-1 of the support frame adopts a triangular structure made of three plates spliced ​​together or integrally molded. The triangular structure not only has stability, which can improve the overall load-bearing strength and vibration resistance of the mounting bracket 1, but also provides a convenient and reliable installation benchmark for the connection between the mounting bracket 1 and the paver frame, and between the limiting plate 5 and the mounting bracket 1 through the reasonable layout of the structural surfaces, simplifying the assembly process; at the same time, with the inherent inclined design of the triangular structure, the mounting bracket 1 forms a shape of "thick on the inside and thin on the outside", which can guide the paving material to flow smoothly to the outside, avoid the accumulation of material at the support, and further ensure the continuity of material blocking and paving operations.

[0027] In some embodiments, such as Figure 2 As shown, two limiting teeth 2-3 are symmetrically installed on the side of the pusher plate body. The support body 1-1 has matching movable slots 1-3 corresponding to the movement trajectory of the limiting teeth 2-3. When the pusher plate body rotates along the rotation axis 7, the two limiting teeth 2-3 slide smoothly in the slots 1-3 simultaneously. This provides guidance and constraint for the up-and-down angular swing of the pusher plate body, preventing deviation and jamming. It also ensures that the rotation angle of the pusher plate assembly 2 is reliably limited by the precise engagement between the lower end of the limiting plate 5 and the limiting teeth 2-3, ensuring that the working angle is stable within the preset range and adapting to the material blocking requirements of different construction scenarios.

[0028] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the limiting teeth 2-3 are provided with no less than two limiting slots (such as three limiting slots). The lower end of the limiting plate 5 can be precisely engaged with different limiting slots, thereby realizing the rapid switching and stable positioning of the push plate assembly 2 between multiple preset working positions, flexibly adapting to the construction needs of different paving layer thicknesses and paving material characteristics, and improving the scene adaptability of the device.

[0029] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the rubber plate 3 is tightly fitted and fixed to the side of the pusher plate body facing the track in the pusher plate assembly 2, and its working end face protrudes beyond the edge of the pusher plate body. This design can not only fill the tiny gap between the pusher plate assembly 2 and the track, preventing the paving material from leaking and spilling from the gap, but also utilize the flexible properties of the rubber material to avoid rigid friction with the track, reduce component wear, and ensure a smooth and undisturbed operation.

[0030] In some embodiments, such as Figure 2 As shown, the limiting plate 5 has multiple limiting adjustment holes 5-1, and the rubber plate 3 has rubber plate adjustment holes 3-1. Each adjustment hole is designed as an elongated oval shape. This elongated oval hole structure provides sufficient margin for fine-tuning of the component's installation position, effectively compensating for errors generated during assembly and improving assembly accuracy. In a further embodiment, the limiting plate 5, after being passed through the limiting adjustment hole 5-1 and the limiting block 6 by the limiting bolt 10, is fastened to the mounting hole 1-2 on the mounting bracket 1 (the mounting hole 1-2 can be designed as a threaded hole or fastened with a nut). This allows for precise fine-tuning of the installation position of the limiting plate 5, ensuring a precise engagement with the limiting teeth 2-3. The rubber plate 3, after being passed through the rubber plate adjustment hole 3-1 by the clamping bolt 9, is fixed to the fastening hole 2-1 on the pusher plate body. This allows for flexible adjustment of the contact angle and position of the rubber plate 3, ensuring the sealing and compatibility of the material blocking part. To facilitate flexible adjustment of the height and angle of the pusher plate assembly 2 relative to the working plane, the limiting plate 5 and the mounting bracket 1 are connected by the limiting block 6. The supporting and positioning function of the limiting block 6 provides a reliable structural foundation for the precise adjustment of the pusher plate assembly 2.

[0031] A second aspect of this utility model also provides a rubber tracked paver, such as... Figure 5 , Figure 6As shown, the paver is equipped with the paver track material blocking device described in any of the above embodiments. Through the appropriate installation of this material blocking device, paving material can be effectively prevented from spilling onto the front of the track, avoiding material compaction that could affect the paving smoothness, further improving the paver's operating quality and construction efficiency, and meeting the high-efficiency and precise construction needs of asphalt concrete road surface and base layers.

[0032] The process of using the track-mounted material-stopping device on this paver: 1. Installation and fixing: Assemble the mounting bracket onto the paver frame and fix it in place with bolts to ensure the overall stability of the device; 2. Angle adjustment: Based on the thickness of the layer to be paved and the characteristics of the paving material, rotate the pusher plate assembly to the appropriate working angle, and lock the preset position by engaging the limit plate and the limit tooth in the slot. 3. Precise fine-tuning: The position of the components is fine-tuned by adjusting the elongated holes on the limit plate and rubber plate, in conjunction with the bolts, to compensate for assembly errors and ensure that the rubber plate and the track fit and seal tightly. 4. Operation: During paver construction, the material blocking devices on both sides work independently. The rubber plate prevents leakage of paving material, and the triangular bracket guides the material flow to avoid accumulation. 5. Maintenance and adjustment: After construction, the device can be disassembled as needed, or worn parts can be replaced individually. Alternatively, steps 2-3 can be repeated to adjust the angle and position according to different construction scenarios.

[0033] Furthermore, those skilled in the art will understand that although some embodiments described herein include certain features found in other embodiments but not others, combinations of features from different embodiments are also within the scope of protection of this utility model and form different embodiments. For example, in the embodiments described above, those skilled in the art can use them in combination based on known technical solutions and the technical problems to be solved by this application.
