Description

Technical Field

[0001] The invention relates to the technical field of road construction machinery, and in particular to a shoulder-side gravel blind ditch spreading vehicle and a spreading method. Background Art

[0002] Blind ditch spreader is a mechanical equipment specially used for laying blind ditch in road construction. It is widely used in highway, municipal road and railway construction. Blind ditch is a key structure to remove water from the road surface or roadbed by setting up a gravel layer, which helps to prevent the softening, settlement and other diseases of the roadbed. Blind ditch spreader uses automated mechanical devices to evenly spread gravel into the blind ditch, replacing the traditional manual laying method, greatly improving construction efficiency while reducing labor intensity and construction costs.

[0003] In the existing technology, most gravel spreading mechanisms lack precise control, and uneven distribution of gravel is prone to occur during the spreading process, resulting in insufficient or excessive thickness of gravel in some parts of the blind ditch, which directly affects the drainage performance. On the other hand, existing equipment generally lacks real-time detection and feedback adjustment functions, and cannot dynamically adjust spreading parameters to cope with complex construction environments.

[0004] In response to the above-mentioned technical problems, the inventor proposed a shoulder-side gravel blind ditch spreading vehicle and spreading method. By combining detection and feedback adjustment technology, the gravel distribution status in the blind ditch is monitored in real time, and the spreading parameters are automatically adjusted to ensure the thickness and distribution uniformity of the gravel, so as to improve the construction quality and efficiency and meet the high-precision requirements of modern road construction for blind ditch construction. Summary of the invention

[0005] In view of at least one of the above technical problems, the present invention provides a shoulder-side gravel blind ditch spreading vehicle and spreading method, which uses a detection feedback mechanism to detect gravel in the blind ditch to improve construction quality and efficiency.

[0006] According to a first aspect of the present invention, there is provided a shoulder-side gravel blind ditch spreading vehicle, comprising: A vehicle body, including a frame, and a wheel assembly connected to the frame; The spreading mechanism comprises a barrel fixedly arranged on the frame, a discharge port provided at the bottom of the barrel, and a guide plate connected to the discharge port and extending to the outside of the vehicle body, wherein the discharge port is also provided with a flow control component, and the guide plate is connected to the discharge port in a relatively rotatable manner; A driving mechanism, fixedly arranged on the vehicle body, and used for driving the vehicle body to move; A detection feedback mechanism is fixed on the frame, comprising a detection component and a feedback component, wherein the detection component is used to detect the thickness and density of the gravel paving and generate a detection result, and the feedback component is used to generate a feedback signal from the detection result; The control mechanism is electrically connected to the detection feedback mechanism, the spreading mechanism and the driving mechanism, and is used to receive the feedback signal of the feedback component, adjust the flow rate of the flow control component in the spreading mechanism and the angle of the guide plate, and control the travel speed of the driving mechanism.

[0007] In some embodiments of the present invention, the barrel further has an anti-clogging vibration assembly inside, including a vibration member fixedly connected to the barrel and a first driving member for driving the vibration member.

[0008] In some embodiments of the present invention, the flow control assembly includes a baffle plate disposed at the discharge port, and a second driving member having one end fixedly connected to the baffle plate and the other end fixedly connected to the barrel.

[0011] In some embodiments of the present invention, the detection component is arranged on one side of the guide plate outlet, and includes a thickness sensor and a density sensor.

[0012] In some embodiments of the present invention, the control mechanism also has a display component and an alarm component. The display component is used to display the driving speed of the vehicle body, the guide plate angle, the discharge speed of the discharge port and the uneven spreading position, and the alarm component is used to alarm when the spreading is uneven.

[0013] According to a second aspect of the present invention, a method for spreading gravel blind ditch on the shoulder side is also provided, comprising the following steps: Start the spreading vehicle, set the gravel paving thickness, density, vehicle speed, guide plate angle and discharge port flow rate, and start the vibrating element to vibrate the inside of the barrel; The thickness and density of the gravel paving are detected in real time through the detection component, and the detection data is transmitted to the feedback component to generate a feedback signal. The vehicle speed, guide plate angle, discharge port flow rate and uneven spreading position are displayed in real time through the display component; The control mechanism receives the feedback signal and determines whether the detection result is within the set range; When the detection result is within the set range, continue to spread the material and detect; When the detection result is not within the set range, an alarm signal is sent out through the alarm component to perform supplementary spreading; After the supplementary spreading, the machine continues to move forward, and dynamically adjusts the discharge flow rate of the flow control component, the angle of the guide plate, and the travel speed of the driving mechanism according to the detection result.

[0014] In some embodiments of the present invention, the determining whether the detection result is within a set range further includes the following steps: The actual detection data is compared with the target range through the control mechanism to calculate the deviation value of thickness and density; When the deviation values ​​of thickness and density are less than or equal to the set allowable deviation, the test result is judged to be within the set range; When the deviation value of thickness or density is greater than the set allowable deviation, it is determined that the test result is not within the set range; The position beyond the set range and the corresponding data are recorded and transmitted to the control mechanism.

[0016] The beneficial effects of the present invention are as follows: the present invention realizes real-time monitoring and dynamic adjustment of the thickness and density of gravel paving through the combination of the detection feedback mechanism and the control mechanism, thereby ensuring the uniformity of gravel paving and improving the quality and drainage performance of blind ditch construction. The detection feedback mechanism can generate detection results in real time and convert them into feedback signals.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 5 The shoulder side gravel blind ditch spreader shown includes: A vehicle body 1 includes a frame 11 and a wheel assembly 12 connected to the frame 11; The spreading mechanism 2 includes a barrel 21 fixedly mounted on the frame 11, a discharge port 21a provided at the bottom of the barrel 21, and a guide plate 22 connected to the discharge port 21a and extending to the outside of the vehicle body 1. The discharge port 21a also has a flow control component 23, and the guide plate 22 and the discharge port 21a are relatively rotatably connected. It should be noted that the flow control component 23 has many forms, such as a sliding valve, a rotary valve, or an electronically controlled discharge port 21a adjustment mechanism. It should also be noted that the rotational connection between the guide plate 22 and the discharge port 21a also has many forms, such as hydraulic, electric adjustment, or other adjustable structural forms.

[0024] The driving mechanism 3 is fixedly arranged on the vehicle body 1, and is used for driving the vehicle body 1 to move. It should be pointed out here that the driving mechanism 3 can be in many forms, and can be electric drive, mechanical drive, hydraulic drive and other driving forms.

[0025] The detection feedback mechanism 4 is fixed on the frame 11, and includes a detection component and a feedback component. The detection component is used to detect the thickness and density of the gravel 05 laid and generate a detection result, and the feedback component is used to generate a feedback signal from the detection result. It should be pointed out here that the detection feedback mechanism 4 can be in many forms, among which the detection component can be a laser sensor, or an ultrasonic sensor or other form of detection; the feedback component can also be in many forms, and can be an embedded processor, or a feedback form in the form of wireless communication, etc.

[0026] The control mechanism is electrically connected to the detection feedback mechanism 4, the spreading mechanism 2 and the driving mechanism 3, and is used to receive the feedback signal of the feedback component, adjust the flow rate of the flow control component 23 in the spreading mechanism 2 and the angle of the guide plate 22, and control the travel speed of the driving mechanism 3. It should be pointed out here that the control mechanism has many forms, which can be wireless transmission, optical fiber transmission and other transmission forms.

[0027] The present invention realizes real-time monitoring and dynamic adjustment of the laying thickness and density of gravel 05 through the combination of the detection feedback mechanism 4 and the control mechanism, thereby ensuring the uniformity of the laying of gravel 05 and improving the quality and drainage performance of the blind ditch 03 construction. The detection feedback mechanism 4 can generate the detection result in real time and convert it into a feedback signal. The control mechanism dynamically adjusts the flow rate of the spreading mechanism 2, the angle of the guide plate 22 and the driving speed of the driving mechanism 3 according to the feedback signal to form a closed-loop control system, which significantly improves the level of construction intelligence and efficiency. The optimized design of the flow control component 23 and the guide plate 22 avoids insufficient or excessive spreading of gravel 05 and ensures the continuity and reliability of the construction, thereby reducing the construction cost and improving the construction accuracy and efficiency.

[0028] In some embodiments of the present invention, the barrel 21 further includes an anti-blocking vibration assembly 24, which includes a vibration member fixedly connected to the barrel 21 and a first driving member for driving the vibration member. Figure 5As shown, the present invention effectively solves the problem of accumulation or blockage of gravel 05 in the barrel 21 by arranging an anti-blocking vibration component 24 inside the barrel 21. The vibration component is composed of a vibration member fixedly connected to the barrel 21 and a first driving member driving the vibration member. The vibration member applies periodic vibration or high-frequency vibration to the barrel 21, which can clear the blocked materials, reduce the accumulation resistance of gravel 05, ensure the fluidity of gravel 05 and the smooth operation of the discharge port 21a, significantly improve the continuous working ability of the spreader, reduce the downtime caused by blockage, and reduce the dependence on manual cleaning, thereby improving the construction efficiency and equipment reliability.

[0029] like Figures 1 to 3 As shown, the flow control component 23 includes a baffle 23a arranged at the discharge port 21a, one end of which is fixedly connected to the baffle 23a, and the other end of which is fixedly connected to the barrel 21. The present invention realizes precise control of the flow of crushed stone 05 by arranging the flow control component 23 at the discharge port 21a, including the baffle 23a and the second drive member 23b fixedly connected thereto. The baffle 23a can adjust the opening size of the discharge port 21a according to demand, thereby flexibly controlling the discharge speed and flow of crushed stone 05 to meet the requirements of different construction thicknesses and densities. The second drive member 23b provides stable power support, making the adjustment of the baffle 23a more efficient and accurate, ensuring the uniformity of laying of crushed stone 05, effectively reducing the waste and uneven spreading of crushed stone 05, and improving the construction quality.

[0030] like Figure 1 , Figure 3 As shown, the connection between the guide plate 22 and the discharge port 21a also has a rotating connection assembly 25, including a first connecting rod 25a fixedly connected to the guide plate 22, a second connecting rod 25b connected to the barrel 21, and a rotating member 25c rotatably connected between the first connecting rod 25a and the second connecting rod 25b, and the rotating member 25c is connected to the control mechanism. The present invention realizes the flexible adjustment of the angle of the guide plate 22 by setting the rotating connection assembly 25 at the connection between the guide plate 22 and the discharge port 21a. The rotating connection assembly 25 is composed of the first connecting rod 25a fixedly connected to the guide plate 22, the second connecting rod 25b connected to the barrel 21, and the rotating member 25c rotatably connected between the two. The rotating member 25c is connected to the control mechanism, so that the guide plate 22 can dynamically adjust the spreading angle according to the construction needs, improve the accuracy of the gravel 05 spreading, ensure that the gravel 05 evenly covers the construction area, and can adapt to the construction needs of different shoulder widths or blind ditch 03 angles.

[0031] like Figure 1 , Figure 4As shown, the guide plate 22 includes a fixed plate 22a fixedly connected to the barrel 21 and an adjusting plate 22b slidably arranged on the barrel 21. The adjusting plate 22b has an overlapping portion with the fixed plate 22a and moves closer to or farther from the fixed plate 22a. The present invention achieves flexible adjustment of the spreading width and direction of the gravel 05 by introducing a combined structure of the fixed plate 22a and the adjusting plate 22b in the design of the guide plate 22. The fixed plate 22a is fixedly connected to the barrel 21 to provide basic stability for the diversion; the adjusting plate 22b can slide relative to the fixed plate 22a to adjust the overlapping area between the fixed plate 22a and the fixed plate 22a, thereby controlling the spreading width and coverage of the gravel 05. When the adjusting plate 22b approaches the fixed plate 22a, the spreading range is reduced; when the adjusting plate 22b is away from the fixed plate 22a, the spreading range is expanded, thereby improving the adaptability of the spreading of the gravel 05, being able to meet the construction requirements of different shoulder widths and blind ditches 03, and reducing the waste of the gravel 05.

[0032] like Figure 1 , Figure 5 As shown, the detection component is arranged on the outlet side of the guide plate 22, including a thickness sensor and a density sensor. The present invention realizes real-time monitoring of the laying quality of gravel 05 by arranging the detection component on the outlet side of the guide plate 22, including a thickness sensor and a density sensor. The thickness sensor is used to detect the thickness of the gravel 05 to ensure that the laying layer meets the design requirements; the density sensor is used to detect the density of the gravel 05 to ensure the drainage performance of the blind ditch 03. The arrangement position of the detection component is close to the outlet of the guide plate 22, and the laying data of the gravel 05 can be obtained in real time and accurately, which provides a reliable basis for feedback and adjustment, and effectively improves the uniformity and accuracy of the spreading of the gravel 05.

[0033] In order to make the real-time monitoring of the spreader more intuitive, in some embodiments of the present invention, the control mechanism also has a display component and an alarm component. The display component is used to display the driving speed of the vehicle body 1, the angle of the guide plate 22, the discharge speed of the discharge port 21a, and the uneven spreading position. The alarm component is used to alarm when the spreading is uneven. The present invention realizes real-time monitoring and abnormal prompts of the working state of the spreader by adding a display component and an alarm component to the control mechanism. The display component can intuitively display the driving speed of the vehicle body 1, the angle of the guide plate 22, the discharge speed of the discharge port 21a, and the uneven spreading position, which is convenient for operators to grasp the construction situation at any time and optimize and adjust; the alarm component automatically emits an audible and visual alarm when the spreading is uneven, reminding the operator to intervene in time, effectively improving the intelligence and convenience of the spreader, reducing the construction quality problems caused by uneven spreading, and improving the construction efficiency and the utilization rate of gravel 05.

[0034] According to the second aspect of the present invention, a method for spreading gravel 05 in a blind ditch 03 on the shoulder side is also provided. Figures 6 to 9As shown in , the following steps are included: S10: Start the spreading vehicle, set the thickness and density of the gravel 05, the speed of the vehicle 1, the angle of the guide plate 22 and the flow rate of the discharge port 21a, and start the vibrating element to vibrate the inside of the barrel 21; S20: The thickness and density of the gravel 05 are detected in real time by the detection component, and the detection data is transmitted to the feedback component to generate a feedback signal, and the vehicle body 1 driving speed, the guide plate 22 angle, the discharge port 21a flow rate and the uneven spreading position are displayed in real time by the display component; S30: The control mechanism receives the feedback signal and determines whether the detection result is within a set range; S40: When the test result is within the set range, continue to spread the material and test; S50: When the detection result is not within the set range, an alarm signal is sent out through the alarm component to perform supplementary spreading; S60: Continue to move forward after supplementary spreading, and dynamically adjust the discharge flow of the flow control component 23, the angle of the guide plate 22 and the travel speed of the driving mechanism 3 according to the detection result.

[0035] like Figure 6 As shown, when laying the gravel 05 in the blind ditch 03, first place the shoulder stone 02 on the road side, and then lay the asphalt 01, with a preset blind ditch 03 position between the asphalt 01 and the shoulder stone 02, and spread the gravel 05 on the blind ditch 03 by the spreading vehicle of the present invention, and finally lay another layer of asphalt 01 on the gravel 05 and the asphalt 01.

[0036] like Figure 7As shown, in the specific working process of the blind ditch 03 spreading vehicle of the present invention, when spreading gravel 05 on the blind ditch 03, first, start the spreading vehicle, set the target thickness and density of gravel 05 laying, set the driving speed of the vehicle body 1, the angle of the guide plate 22 and the flow parameters of the discharge port 21a, and start the vibrator to apply vibration to the inside of the barrel 21 to ensure smooth flow of gravel 05. During the operation, the thickness and density of gravel 05 laying are monitored in real time by the detection component, and the detection data is transmitted to the feedback component to generate a feedback signal. At the same time, the driving speed of the vehicle body 1, the angle of the guide plate 22, the flow rate of the discharge port 21a and the uneven spreading position are displayed by the display component, so that the operator can grasp the construction status in real time. The control mechanism receives the feedback signal and determines whether the detection result is within the set range. If the detection result is within the set range, the spreading vehicle continues to move forward to spread and detect gravel 05; if the detection result is not within the set range, the alarm component will send an alarm signal to prompt the operator to re-spread the position that does not meet the standard. After the supplementary spreading is completed, the spreading vehicle continues to move forward and dynamically adjusts the discharge flow of the flow control component 23, the angle of the guide plate 22, and the driving speed of the vehicle body 1 according to the detection results to ensure the quality of subsequent construction. This method can effectively improve the uniformity and accuracy of gravel 05 laying through real-time monitoring, intelligent feedback and dynamic adjustment, and is suitable for a variety of construction scenarios.

[0037] The method provided by the present invention achieves high precision and high efficiency in laying gravel 05 through real-time monitoring, intelligent feedback and dynamic adjustment; the detection component obtains the data of laying thickness and density in real time, and combined with the intuitive feedback of the display component, the operator can grasp the construction status at any time to ensure the uniform spreading of gravel 05; at the same time, the control mechanism automatically judges the construction quality based on the feedback signal, and when the laying result does not meet the standard, the alarm component promptly reminds and guides the supplementary spreading, further improving the construction quality; after the supplementary spreading is completed, the spreading vehicle can automatically adjust the flow rate, angle and speed according to the detection results to optimize the subsequent construction operations. This method significantly improves the intelligent level and efficiency of construction, reduces manual intervention and waste of gravel 05, ensures stable and reliable laying quality, is suitable for a variety of complex construction scenes, and meets the requirements of modern construction for high precision and high efficiency.

[0038] In some embodiments of the present invention, determining whether the detection result is within a set range further includes the following steps: S31: Compare the actual detection data with the target range through the control mechanism, and calculate the deviation value of thickness and density; S32: When the deviation values ​​of thickness and density are less than or equal to the set allowable deviation, it is determined that the test result is within the set range; S33: When the deviation value of the thickness or density is greater than the set allowable deviation, it is determined that the test result is not within the set range; S34: Record the position beyond the set range and the corresponding data, and transmit them to the control mechanism.

[0039] like Figure 8 As shown, the present invention effectively improves the intelligent and precise control capabilities of gravel 05 paving quality by adding detailed steps to determine whether the test results are within the set range. In these steps, the control mechanism compares the test data with the target range, and quickly determines whether the paving results meet the standards by calculating the deviation values ​​of thickness and density. When the paving thickness or density exceeds the allowable deviation, the system can not only accurately determine the abnormality, but also record the position and data beyond the range, and transmit it to the control mechanism, providing a reliable basis for subsequent re-spreading. This design can realize real-time monitoring and precise judgment of paving quality, significantly improve construction efficiency and quality stability, reduce manual intervention and construction errors, and provide precise re-spreading guidance for locations that do not meet the standards to meet high-precision construction requirements.

[0040] In some embodiments of the present invention, the supplementary spreading further comprises the following steps: S51: Marking the area where gravel 05 paving does not meet the requirements based on the deviation value and the driving track of the spreading vehicle; S52: The control mechanism generates a path for retreating to the area that does not meet the requirements and a path for returning to the construction position according to the area that does not meet the requirements; S53: The control mechanism dynamically adjusts the discharge flow rate of the control component, the angle of the guide plate 22 and the travel speed of the spreading vehicle according to the deviation value of the area that does not meet the requirements; S54: the spreading vehicle returns to the area that does not meet the requirements according to the spreading path, and spreads gravel 05 according to the adjusted parameters; S55: After the supplementary spreading is completed, the supplementary spreading area is inspected again by the detection component to verify whether the paving thickness and density of the gravel 05 are within the set range; S56: If the set range is not reached, continue to spread more; S57: After reaching the set range, update the test results and re-spreading records.

[0041] like Fig. 9As shown, the present invention realizes accurate correction of gravel 05 paving areas that do not meet the standards during the re-spreading process, greatly improving the construction quality and efficiency. By marking the areas that do not meet the requirements and generating the re-spreading path, the spreader can automatically plan and accurately reach the problem area to avoid repeated construction; the control mechanism dynamically adjusts the discharge flow, the angle of the guide plate 22 and the driving speed according to the deviation value to ensure the uniformity and density of the gravel 05 paving during the re-spreading process; after the re-spreading is completed, the system re-detects the re-spreading area through the detection component to verify the construction effect, and continues to re-spread if it does not meet the standard until it meets the requirements; updating the detection results and re-spreading records provides data support for subsequent construction, effectively avoiding the impact of uneven spreading on drainage performance, reducing manual intervention and waste of gravel 05 during the construction process, and realizing closed-loop control of construction quality, meeting the needs of high-precision and high-efficiency construction, and is particularly suitable for complex construction scenes.

The vehicle speed, guide plate angle, discharge port flow rate and uneven spreading position are displayed in real time through the display component; The control mechanism receives the feedback signal and determines whether the detection result is within the set range; When the detection result is within the set range, continue to spread the material and detect; When the detection result is not within the set range, an alarm signal is sent out through the alarm component to perform supplementary spreading; After the supplementary spreading, the machine continues to move forward, and dynamically adjusts the discharge flow rate of the flow control component, the angle of the guide plate, and the travel speed of the driving mechanism according to the detection result.

9. The method for spreading gravel blind ditch on the shoulder side according to claim 8, characterized in that: The step of determining whether the detection result is within a set range also includes the following steps: The actual detection data is compared with the target range through the control mechanism to calculate the deviation value of thickness and density; When the deviation values ​​of thickness and density are less than or equal to the set allowable deviation, the test result is judged to be within the set range; When the deviation value of thickness or density is greater than the set allowable deviation, it is determined that the test result is not within the set range; The position beyond the set range and the corresponding data are recorded and transmitted to the control mechanism.

10. The method for spreading gravel blind ditch on the shoulder side according to claim 9, characterized in that: The method further comprises the following steps: Using the deviation value and the travel track of the spreading vehicle, marking areas where gravel paving does not meet the requirements; The control mechanism generates a path for retreating to the area that does not meet the requirements and a path for returning to the construction position according to the area that does not meet the requirements; The control mechanism dynamically adjusts the discharge flow rate of the control component, the angle of the guide plate and the travel speed of the spreading vehicle according to the deviation value of the area that does not meet the requirements; The spreader returns to the area that does not meet the requirements according to the re-spreading path and spreads gravel according to the adjusted parameters; After the filling is completed, the filling area is inspected again by the detection component to verify whether the thickness and density of the gravel paving are within the set range; If the set range is not reached, continue to spread more; After reaching the set range, the test results and re-spreading records are updated.
