Description

Technical Field

[0001] This invention relates to the field of construction sampling technology, specifically to a sampling and collection device for road construction mixtures. Background Technology

[0002] During road construction, the quality of pavement mixtures directly affects the pavement's water-sealing, skid-resistance, and wear-resistance properties. Therefore, on-site sampling and testing of the mixtures is a crucial aspect of construction quality control. Testing asphalt mixtures can reflect the quality of road construction and its operational status. Improving sampling accuracy and efficiency, as well as minimizing the impact of sampling on materials, has always been a key focus and challenge in project control.

[0003] Currently, most asphalt mixture sampling machines on the market use a wheeled walking method, which makes sampling on the paved mixture difficult and cannot meet the requirements for sampling behind the paver. Some drilling sampling equipment generates significant noise during sampling due to the intense friction and vibration between the sampling cylinder and the road surface; after core sampling, the core sample easily detaches from the sampling device and becomes embedded in the existing road borehole, making core sampling difficult and requiring additional tools, thus reducing efficiency. Some sampling equipment also results in the sample becoming stuck inside the device after sampling, requiring additional equipment to remove the sample, which is inconvenient. Summary of the Invention

It provides reliable samples for accurately judging key indicators such as asphalt-aggregate ratio and gradation. The entire sampling process is highly automated, effectively reducing the interference of human factors on the samples and improving the randomness of sampling. After the excavated mixture is separated by the docking groove of the guide plate, it slides down the slope to the belt conveyor assembly, is positioned by the gathering inclined plate, and finally falls into the roof frame to complete the collection.

This allows the device to move forward with the construction equipment without additional downtime, fundamentally avoiding the drawbacks of traditional sampling methods that require interrupting construction. This significantly improves overall operational efficiency. During movement, the central shaft of the parallel sampling mechanism rotates under the drive of an output motor, causing the embedded conical shovels on the four sets of linked sliding shafts to rotate counterclockwise. Centrifugal force causes them to cut into the soil sequentially, achieving continuous and rapid trench excavation and mixture digging. The entire process is smooth and efficient.

[0022] Please see the appendix Figure 1 - Appendix Figure 7 The soil stabilization drip irrigation mechanism 3 is located on the fixed frame 1 and is used to spray solid liquid onto the area after soil covering. The soil stabilization drip irrigation mechanism 3 includes a storage tank 31, an output soil stabilizing agent pump 32, and a spray irrigation pipe 33.

The agent is then sprayed onto the mixed material area temporarily stored inside the roof frame 21, so that the soil in the landfilled area is moistened to reinforce the landfill.

[0023] Please see the appendix Figure 1 - Appendix Figure 6The depth adjustment mechanism 4 is located on the fixed frame 1 and is used to drive the segmented adjustment of the digging depth of the digging structure. The depth adjustment mechanism 4 includes two sets of fixed frames 41, drive screws 42, nut blocks 43, fixed bearings 44, and output motor 45. The two sets of fixed frames 41 are symmetrically fixed to the front and rear side walls of the fixed frame 1. The inner side walls of the fixed frames 41 are rotatably connected to the drive screws 42, and the drive screws 42 are threadedly connected to the nut blocks 43. The inner side walls of the nut blocks 43 are fixedly connected to the fixed bearings 44. Each frame 41 is fixedly connected to an output motor 45. Each output motor 45 is fixedly connected to a drive screw 42. During the displacement process, the output motor 45 of the depth adjustment mechanism 4 starts and drives the drive screw 42 installed at its output end to rotate inside the fixed frame 41. At the same time as the drive screw 42 rotates, the nut sub-block 43 that is threadedly connected to it begins to descend along the inner side wall of the fixed frame 41. The two sets of nut sub-blocks 43 simultaneously drive the parallel sampling mechanism 5 to descend through the fixed bearing 44 installed on themselves.

[0024] Please see the appendix Figure 1 - Appendix Figure 10The parallel sampling mechanism 5 is located on the depth adjustment mechanism 4 and works with the fixed bearing 44 and the roof frame 21 for synchronous excavation and sampling. The parallel sampling mechanism 5 includes a central rotating shaft 51, a cylindrical fixed box 52, a limiting slide 53, a linkage slide 54, an embedded conical shovel 55, a linkage turntable 56, an arc-shaped slide 57, a linkage gear 58, an output motor 59, and a drive gear 510. The front and rear ends of the central rotating shaft 51 are respectively fixedly connected to the inner rings of two sets of fixed bearings 44. The cylindrical fixed boxes 52 are fixedly connected to both sides of the central rotating shaft 51. The inner walls of the cylindrical fixed boxes 52 are provided with four sets of circularly arranged limiting grooves 53. Four sets of linkage sliding shafts 54 are slidably connected between the cylindrical fixed boxes 52 via the four sets of limiting grooves 53. Multiple sets of uniformly arranged, front-to-back embedded conical shovels 55 are fixedly connected to the side walls of each linkage sliding shaft 54. A linkage turntable 56 is rotatably connected to the inner wall of the central rotating shaft 51. The linkage turntable 56 is provided with four sets of uniformly arranged circular arc-shaped grooves 57. A set of linkage sliding shafts 54 is slidably connected inside each arc-shaped groove 57. A linkage gear 58 is fixedly connected to the outer end of the rotating shaft of the linkage turntable 56. The central rotating shaft 51... An output motor 3 59 is fixedly connected to the outer side of the side wall. The output end of the output motor 3 59, located inside the central rotating shaft 51, is fixedly connected to a drive gear 510. The drive gear 510 meshes with a linkage gear 58. An output motor 1 24 installed inside the roof frame 21 starts to generate rotational torque, which is guided to the parallel sampling mechanism 5 by a belt guide assembly 25 installed at the output end. After receiving the rotational torque through the belt guide assembly 25, the central rotating shaft 51 rotates along two sets of fixed bearings 44. Cylindrical fixed boxes 52 and cylindrical fixed bearings 54 are installed on both sides of the central rotating shaft 51. The fixed box 52 rotates counterclockwise along with the four sets of linked sliding shafts 54 that restrict the sliding of the chute 53. After the horizontal array of embedded cone shovels 55 attached to the four sets of linked sliding shafts 54 comes into contact with the soil in sequence, the centrifugally rotating embedded cone shovels 55 excavate parallel trenches in the corresponding area, while excavating the mixture. The embedded cone shovels 55 that collect the mixture and excavate the trenches rotate and detach from the soil. The embedded cone shovels 55 corresponding to the next set of linked sliding shafts 54 begin to insert into the soil and continue to excavate the mixture. With the continuous excavation of the embedded cone shovels 55, a set of trenches is formed in the area.

[0025] Please see the appendix Figure 1 - Appendix Figure 8 The soil stabilizing agent input mechanism 6 is located on the fixed frame 1 and works with the roof frame 21 to output the covering soil stabilizing agent. The soil stabilizing agent input mechanism 6 includes a hopper 61, which is fixedly connected to the top of the fixed frame 1 and located between the central fixed mechanism 2 and the soil stabilizing drip irrigation mechanism 3. The output end of the hopper 61 is provided with a parallel output pipe 62, which extends into the interior of the fixed frame 1. The soil stabilizing agent is spread using the soil stabilizing agent input mechanism 6. The soil stabilizing agent pre-stored in the hopper 61 is guided by the parallel output pipe 62 into the complete trench formed by the V-shaped guide pipe 73.

[0026] Please see the appendix Figure 1 - Appendix Figure 7 The guiding and covering mechanism 7 is located on the fixed frame 1 and is used for forming a straight soil stabilization pit and covering it with soil. The guiding and covering mechanism 7 includes an input frame 71 and an output frame 74. The input frame 71 is fixedly connected to the bottom of the fixed frame 1. A conical guide platform 72 is provided on the side wall of the input frame 71 near the depth adjustment mechanism 4. Equally spaced V-shaped guide tubes 73 are fixedly connected inside the input frame 71 and connected to the output port of the conical guide platform 72. The output frame 74 is fixedly connected to the bottom of the fixed frame 1 near the soil stabilization drip irrigation mechanism 3. Equally spaced trapezoidal output tubes 75 are fixedly connected to the output frame 74 and contact the parallel sampling mechanism 5. The guide covering mechanism 7 is installed in the output direction. The input frame 71 included in the guide covering mechanism 7 is installed in the output direction of the parallel sampling mechanism 5. The multiple trenches excavated by the parallel sampling mechanism 5 will contact the conical guide platform 72 installed on the input frame 71 respectively. The conical surface of the conical guide platform 72 guides the soil into the V-shaped guide pipe 73 installed in parallel on the input frame 71. The soil is guided to both sides by the inclined guide side plate structure of the V-shaped guide pipe 73, gradually forming a complete trench. After the sowing is completed, the trapezoidal output pipe 75 installed on the output frame 74 uses the side wall of the converging trapezoidal structure to guide the soil into the trench, so that the trench is filled and covered with soil.

[0027] This invention also provides a working principle for a sampling and collection device for road construction mixtures: First, the fixed frame 1 is fixed to the traction equipment by the trailer hook 26, front transport wheel assembly 22, and rear transport wheel assembly 23 belonging to the central fixing mechanism 2, and then driven to the construction area. The depth adjustment mechanism 4 and the parallel sampling mechanism 5 are activated, and the traction equipment drives the central fixing mechanism 2 to move linearly. During the displacement, the output motor 45 of the depth adjustment mechanism 4 is started, and the drive screw 42 installed at its output end rotates inside the fixed frame 41. At the same time as the drive screw 42 rotates, the nut sub-block 43 that is threadedly connected to it begins to descend along the inner wall of the fixed frame 41. The two sets of nut sub-blocks 43 simultaneously descend along their own fixed... The fixed bearing 44 drives the parallel sampling mechanism 5 to descend. Simultaneously, the output motor 24 installed inside the roof frame 21 starts, generating rotational torque, which is guided to the parallel sampling mechanism 5 by the belt guide assembly 25 installed at the output end. The central rotating shaft 51 receives the rotational torque through the belt guide assembly 25 and rotates along the two sets of fixed bearings 44. The cylindrical fixed boxes 52 installed on both sides of the central rotating shaft 51, and the four sets of linked sliding shafts 54 that restrict the sliding of the cylindrical fixed boxes 52 via the sliding grooves 53, also rotate counterclockwise. After the transverse array of embedded conical shovels 55 installed on the four sets of linked sliding shafts 54 sequentially contacts the soil, the centrifugally rotating embedded conical shovels 55 excavate parallel trenches in the corresponding areas, simultaneously excavating and bringing out the mixture. The embedded conical shovels 55 collect the mixture and excavate the trenches. 5. Subsequently, it rotates and detaches from the soil, while the next set of linked sliding shafts 54, corresponding to the embedded cone shovel 55, begins to insert into the soil, continuously excavating the mixture. The embedded cone shovel 55 continues to excavate and contacts the guide covering mechanism 7 installed in the output direction of the parallel sampling mechanism 5. The input frame 71 included in the guide covering mechanism 7 is installed in the output direction of the parallel sampling mechanism 5. The multiple trenches excavated by the parallel sampling mechanism 5 will respectively contact the conical guide platform 72 installed on the input frame 71. The conical surface of the conical guide platform 72 guides the soil into the V-shaped guide pipe 73 installed in parallel on the input frame 71. The soil is guided to both sides by the inclined guide side plate structure of the V-shaped guide pipe 73, gradually forming a complete trench. Simultaneously, the soil stabilizing agent is spread using the soil stabilizing agent input mechanism 6. The soil-stabilizing agent pre-stored in bucket 61 is guided by parallel output pipes 62 into the complete trench formed by V-shaped guide pipes 73. After sowing, the trapezoidal output pipe 75 installed on the output frame 74 guides the soil into the trench using the side walls of the converging trapezoidal structure, thus filling and covering the trench with soil. The embedded conical shovel 55 carries the mixture to contact the guide inclined plate 27 located on the inner side wall of the roof frame 21, and passes through the guide inclined plate 27 through the docking groove 28 installed on the guide inclined plate 27. The mixture falls onto the guide inclined plate 27 and slides down the inclined guide inclined plate 27 onto the belt conveyor assembly 29, where it is conveyed and positioned by the gathering inclined plate 210 installed above the belt conveyor assembly 29, finally falling into the roof frame 21 for collection.Alternatively, depending on the different root depth requirements of the mixture, the output motor 3 59 mounted on the central rotating shaft 51 can be started. The output motor 3 59 drives the drive gear 510 mounted on its output end to rotate, and the linkage gear 58 meshing with the drive gear 510 drives the fixed linkage turntable 56 to rotate inside the drive gear 510. The four sets of arc-shaped sliding grooves 57 mounted on the linkage turntable 56 also rotate accordingly. At the same time, the four sets of linkage sliding shafts 54 that slide and connect with the arc-shaped sliding grooves 57 also move outward or outward along the limiting sliding grooves 53 along with the rotation of the arc-shaped sliding grooves 57. This involves moving inwards, causing the diameter of the parallel sampling mechanism 5 to decrease or increase, while simultaneously changing the digging depth. In conjunction with the descent and elevation drive distance of the depth adjustment mechanism 4, the parallel sampling mechanism 5 excavates the mixture at different depths. Once the mixture reaches the interior of the roof frame 21, the soil-stabilizing drip irrigation mechanism 3 is activated. The soil-stabilizing agent pump 32 generates a pumping force to draw the soil-stabilizing agent stored in the storage tank 31 into the irrigation pipe 33. The agent is then sprayed onto the soil in the extraction area through the irrigation pipe 33, moistening the soil in the landfill area and thus reinforcing the landfill.
