[0026] 1. Equipment assembly and preparation

[0027] First, assemble the frame 1 according to the design drawings to ensure that the four walking wheels are firmly installed and can move smoothly. Install the hydraulic mechanism 2 at the designated position on the frame 1 and connect it to the power supply or power source. Check whether the hydraulic pipeline is unobstructed and there is no leakage.

[0028] The movable support 4 is driven by the driving component of the hydraulic mechanism 2 and connected to the support column of the frame 1 to ensure that the movable support 4 can slide up and down smoothly. The first mounting frame 5 and the second mounting frame 6 are respectively fixed under the frame 1 for installing the pressing roller 7 and the crushing mechanism 9.

[0029] 2. Installation and commissioning of the pressing roller 7

[0030] Connect the pressing roller 7 to the first mounting frame 5 through components such as bearings to ensure that the pressing roller 7 can rotate freely. Install the vibrator 8 on the pressing roller 7 and connect the power supply for testing to ensure good vibration effect.

[0031] Install a plurality of bumps 11 and grooves 12 on the outer wall of the pressing roller 7 in a staggered and evenly distributed manner. The dimensions, shapes and distributions of the bumps and grooves need to be precisely processed according to the design requirements to ensure the flattening effect.

[0032] 3. Installation and commissioning of the crushing mechanism 9

[0033] Fix the rotating motor 13 at the upper end of the second mounting frame 6 and fix it firmly through fasteners such as bolts. According to the specific type of the transmission mechanism 14, such as a belt transmission mechanism or a gear transmission mechanism, install the transmission components one by one to ensure that the transmission path is correct and there is no interference phenomenon.

[0034] Two rotating shafts 15 respectively pass through the holes of the second mounting frame 6 and are connected to the slave transmission components of the transmission mechanism 14. Install the upper and lower cutter disks 16 at the lower ends of the two rotating shafts 15 respectively, and install a plurality of cutter heads 17 on the outer periphery of the cutter disks 16.

[0035] 4. Installation and commissioning of the stone cleaning mechanism 10

[0036] The first bucket 18 is slidably connected to the front end of the frame 1 through components such as slide rails or sliders to ensure that the first bucket 18 can move left and right along the horizontal direction. The front wall of the second bucket 19 is provided with a slider matching the slideway on the rear wall of the first bucket 18. Install the second bucket 19 behind the first bucket 18 and adjust the cooperation between the slider and the slideway to ensure that the two can slide smoothly.

[0037] Install the adjusting rod 20 on the side wall of the second bucket 19 and fix it through threaded connection or other means. By rotating the adjusting rod 20, the distance between the first bucket 18 and the second bucket 19 can be changed to meet the cleaning requirements of stones of different sizes.

[0038] 5. Commissioning and Trial Operation of the Whole Machine

[0039] After the installation and commissioning of each component are completed, the whole flattening device is commissioned. Start the hydraulic mechanism 2, adjust the height of the movable support 4 to ensure that the pressing roller 7 and the crushing mechanism 9 can contact the ground. Start the rotating motor 13 and the vibrator 8, and check the working conditions of the crushing mechanism 9 and the pressing roller 7.

[0040] Push the equipment to conduct trial operation on the simulated soft soil subgrade, and observe the crushing effect of the crushing mechanism 9 on the stones, the cleaning effect of the stone cleaning mechanism 10 on the stones, and the flattening effect of the pressing roller 7 on the road surface. According to the trial operation results, make necessary adjustments and optimizations to the equipment to ensure that all performance indicators meet the design requirements.

[0041] Through the description of the above specific implementation manners, technicians can clearly understand the structural composition, working principle and operation method of the flattening device for soft soil subgrade of the present utility model, so as to carry out actual production and use.

[0042] Working Process:

[0043] First, connect with the driving equipment through the connecting frame 3, and move the flattening device to the working area of the soft soil subgrade to be processed through the four walking wheels under the frame 1. Check whether each component is firmly installed, and whether the hydraulic mechanism 2, the rotating motor 13, the vibrator 8, etc. are in normal state. According to the subgrade conditions, adjust the distance between the bucket one 18 and the bucket two 19 in the stone cleaning mechanism 10 through the adjusting rod 20 to meet the cleaning requirements of stones of different sizes. Connect the power supply or power source, and start the equipment such as the hydraulic mechanism 2, the rotating motor 13 and the vibrator 8 for preheating and preliminary commissioning.

[0044] During operation, adjust the sliding position of the bucket one 18 along the left and right directions at the front end of the frame 1, scoop up the crushed stones, soil blocks and other impurities and move them to one side of the equipment or the designated position. By adjusting the distance between the bucket one 18 and the bucket two 19, it can be ensured that stones of different sizes can be effectively cleaned.

[0045] Start the rotating motor 13, and drive the cutter head 16 and the cutter tip 17 to rotate through the transmission mechanism 14. Lower the crushing mechanism 9 to a position close to the ground, and the cutter tip 17 begins to contact and crush the large stones or hard soil blocks on the road surface. The size of the crushed stones is reduced, which is convenient for subsequent cleaning and flattening.

[0046] According to the subgrade conditions, adjust the height of the movable support 4 through the hydraulic mechanism 2, so that the pressing roller 7 descends to an appropriate position to ensure that it can contact the road surface to be flattened.

[0047] Before the pressing roller 7 starts to rotate, start the vibrator 8. The vibration generated by the vibrator 8 can enhance the flattening effect of the pressing roller 7 and make the soil layer more compact.

[0048] Start the rotating device of the pressing roller to make it start rotating and move forward. The staggered design of the bumps 11 and grooves 12 on the pressing roller can penetrate into the soil and discharge the excess soil, thus achieving uniform flattening. During the flattening process, the speed and vibration frequency of the road roller can be adjusted as needed.

[0049] According to the need, perform multiple flattening treatments on the same area to improve the compactness and flatness of the road surface. After each flattening, the road surface quality can be checked and adjusted as needed.

[0050] During and after the flattening process, use measuring tools (such as leveling rods, measuring instruments, etc.) to monitor the road surface quality. Check whether the indicators such as the flatness and compactness of the road surface meet the design requirements.

[0051] Evaluate the flattening effect based on the monitoring results. If any non-compliant areas are found, additional pressing or re-construction can be carried out.

[0052] Record the monitoring results and evaluation effects and feedback them to the technical personnel or project leader. Make necessary adjustments and improvements according to the feedback opinions.

[0053] Through the above working process, the flattening device for soft soil subgrade can effectively crush, clean and flatten the road surface, improving the quality and safety of the road surface.
