Description

Technical Field

[0001] This utility model relates to a width-adjustable material distribution baffle control system and a paver, belonging to the field of pavers. Background Technology

[0002] In road paving operations, existing material distribution barriers generally employ a mechanically assembled structure. Before and during operation, operators must manually select and assemble the corresponding specifications of material distribution barrier components based on the actual paving width requirements. This process requires multiple people to collaborate on barrier alignment, fastening of connectors, and other operations, consuming significant manpower and significantly extending preparation or adjustment time. The operation is cumbersome and inefficient. Especially in situations where paving width frequently changes, such as widening sections of municipal roads, ramp connections, and multi-lane phased paving, repeated machine stops are necessary to disassemble old-specification barriers and reassemble new-specification barriers. This not only leads to frequent interruptions in construction processes, drastically reducing overall paving efficiency, but may also cause misalignment of the pavement layers due to downtime, indirectly affecting the quality of road construction. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a width-adjustable material distribution baffle control system and a paver. When the paving width changes, the width of the material distribution baffle automatically adjusts without manual adjustment, which can reduce the labor intensity of the operator and improve construction efficiency.

[0004] To achieve the above objectives, this utility model employs a width-adjustable material distribution baffle control system, comprising: The material distribution baffle is installed on the frame of the paver; A follow-up support baffle is installed on the frame and cooperates with the material distribution baffle. The follow-up support baffle has the freedom to move along the material distribution direction. It is pushed by the material distribution baffle and extends or retracts synchronously with it to achieve dynamic support for the material distribution baffle. The sensor, installed on the side baffle of the ironing board, is used to detect the distance S between the outer end face of the material distribution baffle and the side baffle of the ironing board in real time. The controller is connected to the material distribution baffle and the sensor via electrical signals. The controller receives the distance S signal transmitted by the sensor and determines whether S is within a preset range. If it exceeds the preset range, it outputs an electrical signal to the material distribution baffle to control the baffle to adjust its width so that the distance S is kept within the preset range, thereby realizing the automatic adjustment of the width of the material distribution baffle.

[0005] As an improvement, the material distribution baffle includes a fixed baffle, a telescopic baffle, and a power element; the fixed baffle is fixedly connected to the frame; the telescopic baffle is slidably engaged with the fixed baffle and can reciprocate relative to the fixed baffle along the material distribution direction; the fixed end of the power element is connected to the fixed baffle or the frame, and the output end is drivenly connected to the telescopic baffle to drive the telescopic baffle to move; the power element is electrically connected to the controller and receives the electrical signal output by the controller, and drives the telescopic baffle to extend or retract according to the electrical signal to adjust the overall width of the material distribution baffle.

[0006] As an improvement, the follower support baffle is provided with several grooves extending along the material distribution direction; the telescopic baffle of the material distribution baffle is provided with a pin adapted to the groove, the pin passes through the groove and can slide along the length of the groove; when the telescopic baffle moves to a preset stroke, the pin slides to the end edge of the groove and abuts against the inner wall of the groove, thereby pushing the follower support baffle and the telescopic baffle to extend or retract synchronously.

[0007] As an improvement, the power element is a hydraulic cylinder or an electric push rod.

[0008] As an improvement, the material distribution baffles are arranged symmetrically on the paver frame, with the two sets of material distribution baffles corresponding to the left and right paving areas of the paver, respectively.

[0009] As an improvement, the sensor is an ultrasonic distance sensor or a laser distance sensor.

[0010] As an improvement, the controller is the main controller of the paver, and the electrical signals transmitted between the controller, the material distribution baffle, and the sensors are CAN bus signals.

[0011] In a second aspect, this utility model also provides a paver, wherein the paver integrates the aforementioned width-adjustable material distribution baffle control system.

[0012] Compared with existing technologies, the width-adjustable material distribution baffle control system of this utility model achieves adaptive adjustment of the material distribution baffle width by using sensors to detect distance signals in real time and the controller to automatically issue adjustment commands. This eliminates the need for manual assembly or replacement of the baffle, significantly reducing the operator's labor intensity, saving labor costs, and substantially improving construction efficiency. Simultaneously, the follow-up support baffle can extend or retract synchronously with the material distribution baffle, providing dynamic support and effectively improving the structural stability and stress balance of the baffle during width adjustment. This prevents deformation or swaying caused by baffle extension and retraction, ensuring the continuity of paving operations and the quality of road construction.

[0013] This utility model is highly adaptable, especially suitable for construction conditions with varying paving widths (such as widening sections of municipal roads, ramp connections, multi-lane phased paving, etc.), and has better compatibility with pavers equipped with hydraulic telescopic screeds, further expanding the application scenarios of the equipment.

Detailed Implementation

[0016] 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 with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, a width-adjustable material distribution baffle control system includes a material distribution baffle 2, a sensor 3, an ironing plate side baffle 4, a controller 5, and a follow-up support baffle 6. The material distribution baffle 2 is installed on the frame 1 of the paver. As the core execution component for material guidance and width adaptation in paving operations, its width can be flexibly adjusted to match the needs of different paving conditions. The follow-up support baffle 6 is installed on the frame 1 and is in transmission cooperation with the material distribution baffle 2. It retains only one degree of freedom along the material distribution direction. It can be pushed synchronously and extend or retracted when the material distribution baffle 2 moves. This design can provide dynamic and precise support for the material distribution baffle 2 in the telescopic state, effectively disperse the force on the material distribution baffle 2, avoid deformation, shaking or stress concentration caused by changes in telescopic length, and ensure the structural stability and service life of the material distribution baffle 2. The sensor 3 is installed on the side baffle 4 of the ironing board, and can detect the distance S between the outer end face of the material distribution baffle 2 and the side baffle 4 of the ironing board in real time and accurately, so as to provide a continuous and reliable signal basis for width adjustment and ensure the timeliness and accuracy of the adjustment action. The controller 5 establishes connections with the material distribution baffle 2 and the sensor 3 via electrical signals. As the control center of the system, it can quickly receive the distance S signal transmitted by the sensor 3 and automatically determine whether S is within the preset range of the target paving width. If S exceeds the range, the controller 5 immediately outputs a precise electrical signal to the material distribution baffle 2 to drive it to adjust its width, so that the distance S is always stably kept within the preset range. Ultimately, the controller achieves fully automatic adaptive adjustment of the width of the material distribution baffle 2 without manual intervention.

[0018] In some embodiments, such as Figure 3 As shown, the material distribution baffle 2 adopts a modular telescopic structure, specifically including a fixed baffle 201, a telescopic baffle 202 and a power element 203. The width of the material distribution baffle 2 can be precisely and controllably adjusted through the coordinated cooperation of the three. The fixed baffle 201 is fixedly connected to the frame 1, forming a stable installation base and structural support for the material distribution baffle 2, ensuring the overall installation reliability; the telescopic baffle 202 and the fixed baffle 201 adopt a sliding fit design, which can smoothly and steadily reciprocate relative to the fixed baffle 201 along the material distribution direction, providing an execution basis for width adjustment. The power element 203 serves as the core of the telescopic drive. Its fixed end can be selectively connected to the fixed baffle 201 or the frame 1 (to adapt to different installation spaces and force requirements), and its output end is connected to the telescopic baffle 202 for transmission, providing a stable driving force for the telescopic baffle 202. At the same time, the power element 203 establishes an electrical connection with the controller 5, and can receive the precise control electrical signals output by the controller 5 in real time. According to the instructions of the electrical signals, it can precisely drive the telescopic baffle 202 to extend or retract, thereby realizing the flexible and efficient adjustment of the overall width of the material distribution baffle 2 to adapt to different paving width requirements.

[0019] In some embodiments, the follower support baffle 6 and the telescopic baffle 202 adopt a groove-pin cooperation structure to achieve the dual effects of synchronous movement and stable support: the follower support baffle 6 is provided with a plurality of grooves extending along the material distribution direction, and the extension direction of the grooves is consistent with the movement trajectory of the telescopic baffle 202, providing a guiding basis for synchronous movement; The telescopic baffle 202 of the material distribution baffle 2 is provided with a pin that is adapted to the slide groove. The pin passes through the slide groove and slides against the inner wall of the slide groove, allowing it to slide smoothly along the length of the slide groove and reducing frictional resistance during relative movement. When the telescopic baffle 202 moves to a preset stroke along the material distribution direction under the drive of the power element 203, the pin slides to the end edge of the slide groove and abuts tightly against the inner wall of the slide groove. The driving force is transmitted through the abutment, thereby driving the follower support baffle 6 to extend or retract synchronously with the telescopic baffle 202, ensuring that the follower support baffle 6 always provides effective support for the telescopic baffle 202 and preventing the telescopic baffle 202 from deflecting or swaying due to the increase in its extension length.

[0020] In some embodiments, the power element 203 is preferably a hydraulic cylinder or an electric push rod, both of which have the characteristics of stable linear drive, sufficient output force and fast response speed, and can accurately match the width adjustment requirements of the material distribution baffle 2. When adapting to traditional hydraulically driven pavers, hydraulic cylinders are preferred, as they can utilize the paver's existing hydraulic system for power supply, eliminating the need for an additional independent power source and simplifying system integration. When adapting to electric or hybrid pavers, electric push rods are preferred, as they offer advantages such as low energy consumption, high control precision, and low maintenance costs. Furthermore, they are seamlessly compatible with the paver's electric control system, further enhancing the overall system's energy efficiency, environmental friendliness, and adjustment accuracy.

[0021] In some embodiments, the material distribution baffles 2 are arranged symmetrically on the paver frame 1 to form two independent material distribution adjustment units, corresponding to the left and right paving areas of the paver, respectively. This symmetrical arrangement design can realize independent adaptive adjustment of the paving width on both sides, which can adapt to conventional paving operations with symmetrical widths, and can also flexibly cope with complex working conditions such as road widening sections and ramp connections where the widths on both sides are inconsistent, greatly improving the system's adaptability to working conditions and operational flexibility.

[0022] In some embodiments, the sensor 3 is selected as an ultrasonic distance sensor or a laser distance sensor, both of which can meet the real-time detection requirements of distance S and are suitable for the complex working conditions of paving operations. Among them, ultrasonic distance sensors have the advantages of controllable cost and strong resistance to dust interference, and are suitable for conventional paving scenarios with moderate requirements for detection accuracy; while laser distance sensors have the characteristics of high detection accuracy and fast response speed, and can be accurately matched to high-precision paving operations with strict requirements for distance detection error, so as to achieve flexible selection as needed.

[0023] In some embodiments, the controller 5 is preferably the main controller of the paver, without the need for an additional independent control module. This can make full use of the existing control resources of the paver, simplify the overall system structure, and reduce integration costs. Meanwhile, the electrical signals transmitted between the controller 5, the material distribution baffle 2 (with the core being the power element 203), and the sensor 3 are transmitted via CAN bus signals. This signal transmission method has the advantages of strong anti-interference capability, stable transmission rate, and simple wiring, which can ensure the efficient and accurate transmission of distance detection signals and width adjustment commands, thereby improving the responsiveness and operational reliability of the entire control system.

[0024] In a second aspect, this utility model also provides a paver, wherein the paver integrates a width-adjustable material distribution baffle control system as described in any of the above embodiments; Through the integrated application of this control system, the paver can achieve fully automatic adaptive adjustment of the width of the material distribution baffle when the paving width changes, without the need for manual intervention. This not only reduces the labor intensity of operators and saves labor costs, but also improves paving efficiency and road construction quality. It is especially suitable for complex construction conditions with varying paving widths, significantly expanding the application scenarios and practical value of the paver.

[0025] The operation process of the width-adjustable material distribution baffle control system: 1. Real-time distance detection: When the paver starts paving operation, the sensor 3 (ultrasonic or laser distance sensor) installed on the side baffle 4 of the screed plate continuously and in real time detects the distance S between the outer end face of the material distribution baffle 2 and the side baffle 4 of the screed plate, and transmits the detected distance signal stably to the controller 5 through the CAN bus. 2. Signal Judgment and Command Output: After receiving the distance S signal transmitted by sensor 3, controller 5 quickly compares it with the preset range for judgment. (1) If S is within the preset range, it means that the current width of the material distribution baffle 2 is compatible with the paving width. The controller 5 does not output adjustment commands, the material distribution baffle 2 remains in its current state, and the paver continues to pave normally. (2) If S exceeds the preset range (e.g., when paving to a wider section of the road, S is greater than the preset value; or when paving to a narrow area, S is less than the preset value), the controller 5 immediately generates a precise electrical control signal according to the direction and magnitude of the deviation, and transmits it to the power element 203 (hydraulic cylinder or electric push rod) of the material distribution baffle 2 via the CAN bus. 3. Adjustment of the width of the material distribution baffle: After receiving the electrical signal from the controller 5, the power element 203 drives the telescopic baffle 202 to reciprocate relative to the fixed baffle 201 along the material distribution direction. (1) When S is greater than the preset value (the material distribution width needs to be widened), the power element 203 drives the telescopic baffle 202 to extend outward, and the overall width of the material distribution baffle 2 increases; (2) When S is less than the preset value (the material distribution width needs to be narrowed), the power element 203 drives the telescopic baffle 202 to retract inward, and the overall width of the material distribution baffle 2 decreases. 4. Synchronous movement of the follow-up support: During the movement of the telescopic baffle 202, the pin on its surface slides along the groove on the follow-up support baffle 6; when the telescopic baffle 202 moves to the preset stroke, the pin abuts against the edge of the groove end, pushing the follow-up support baffle 6 to extend or retract synchronously, always providing dynamic support for the telescopic baffle 202, avoiding deformation or shaking due to changes in the telescopic length, and ensuring the stability of material distribution; 5. When the paver completes the paving operation or needs to be stopped, the operator turns off the paving function. After receiving the stop signal, the controller 5 can control the power element 203 to drive the telescopic baffle 202 to retract to the initial position (minimum width state) to facilitate equipment parking and transportation.

[0026] 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.
