At the same time, it can reduce material costs, making the use of construction waste as roadbed filler more and more widespread.

[0003] Construction waste used as roadbed filler is mostly bricks and concrete blocks. After the bricks and concrete blocks are transported to the construction site, a roller with staggered crushing teeth on a steel wheel is generally used to crush and compact the construction waste. However, after the bricks and concrete blocks are crushed, there are still large gaps between them. In the compaction test of construction waste sampling, after the surface is compacted and leveled, it is impossible to determine whether the interior is completely compacted, which will cause deviations in the test results. If the construction compaction force is small according to the test data, it will affect the construction quality. In addition, the main bricks and concrete blocks in construction waste are two different materials. In order to ensure that the results of the compaction test are objective and accurate, it is necessary to evenly mix the two materials of bricks and concrete blocks and the size of the broken blocks.

[0020] Example 2, reference Figure 1 - Figure 8 The output end of the hydraulic seat 2 is connected to a compacting seat 21, a side wall of the compacting seat 21 is provided with an annular groove, the inner side wall of the annular groove is connected with a rubber ring 23 for pressing and sealing the compacting cylinder 3, a receiving groove is provided at the bottom end of the compacting seat 21, the inner end surface of the receiving groove is connected with an air pressure sensor 24 for detecting the air pressure change in the compacting cylinder 3, a plurality of one-way components are arranged on the periphery of the air pressure sensor 24, and the one-way components are connected with a flattening plate 26; Furthermore, the output end of the hydraulic seat 2 is fixedly connected to the top of the compacting seat 21, and the top of the compacting seat 21 is fixedly connected with a micro air pump 22. The output end of the micro air pump 22 is connected to the annular groove on the outer wall of the compacting seat 21. The inner wall of the annular groove of the compacting seat 21 is fixedly connected to both ends of the rubber ring 23. The inner end surface of the receiving groove at the bottom end of the compacting seat 21 is fixedly connected to the end of the air pressure sensor 24. The inner end surface of the receiving groove is fixedly connected to the top of the flattening plate 26 through a plurality of electric push rods 25. The flattening plate 2 6 side wall is slidably connected with the inner wall of the storage groove, the one-way component is composed of a slide bar 28 and two pillars 27, the outer walls at both ends of the slide bar 28 are slidably connected with the inner walls of the upper and lower pillars 27, and a tension spring 29 is sleeved on the outer wall of the slide bar 28. The end of the pillar 27 located at the top is fixedly connected with the inner end surface of the storage groove at the bottom end of the compaction seat 21, and the end of the pillar 27 located at the bottom is fixedly connected with the top of the flat plate 26. The connection height of the flat plate 26 and the two pillars 27 is consistent with the depth of the storage groove; It should be noted that after the crushed materials of construction waste are loaded into the compaction cylinder 3, the U-shaped plate 11 and the lifting arc plate 12 are used to move and impact, so that the crushed materials in the compaction cylinder 3 are vibrated and compacted, and then the hydraulic seat 2 is started to press the compaction seat 21 downward. The compaction seat 21 is pressed into the compaction cylinder 3 and will vibrate and press down, and the crushed materials in the compaction cylinder 3 are gradually compacted. After compaction once, a part of the crushed materials are refilled, and the compaction seat 21 is pressed down for compaction. After the compaction of the crushed materials in the compaction cylinder 3 is completed, the compaction seat 21 is slowly pressed down from top to bottom, and at the same time, the micro air pump 22 is started to pass gas into the rubber ring 23, so that the rubber ring 23 is compressed and expanded, and the rubber ring 23 will be pressed against the inner wall of the extension sleeve 6 and the compaction cylinder 3, so that the bottom of the compaction seat 21 is in a relatively sealed state during the downward pressing process, and the bottom of the compaction seat 21 The air pressure between the compacted crushed materials will gradually increase. Before pressing down, the electric push rod 25 is used to push out the leveling plate 26, so that the air pressure sensor 24 in the storage groove at the bottom of the compaction seat 21 can sense and detect the external air pressure. When the leveling plate 26 is pushed down, the two pillars 27 slide on the slide bar 28 and stretch and separate the tension spring 29. In the compaction process, the two pillars 27 are butted against each other to support the leveling plate 26 to ensure the flatness of the leveling plate 26 and the bottom of the compaction seat 21. If the crushed materials in the compaction cylinder 3 are not completely compacted, as the air pressure continues to increase, the high-pressure gas will enter the gap between the crushed materials along the gap, so that the air pressure below the compaction seat 21 and between the compacted crushed materials will suddenly decrease during the overall increase, which is sensed by the air pressure sensor 24 and the signal is transmitted; A further advantage of adopting the above method is that after the compaction of the crushed materials is completed, the state of the rubber ring 23 and the leveling plate 26 on the compaction seat 21 can be changed to detect whether the crushed materials are completely compacted, thereby avoiding the problem that the interior of the crushed materials is difficult to directly observe and ensuring the reliability of the compaction test results.

[0021] When the present invention is in use, the bottom plate 4 of the compacting cylinder 3 is installed and docked with the multiple positioning columns 5 on the base 1, so that the axis of the compacting cylinder 3 and the compacting seat 21 are located on the same vertical line, and then the electric control guide ring 9 starts to slide on the outer wall of the guide column 7, and the electric control guide ring 9 moves the lifting arc plate 12 and the semi-guide bucket 13 to the bottom and top of the extension sleeve 6 respectively through the U-shaped plate 11, and uses the electric control rod 10 to push the two semi-guide buckets 13 to dock, and the feeding motor 17 is started to drive the feeding shaft 18 to rotate slowly. The rotation of the feeding shaft 18 will drive the spiral blade 19 to rotate in the feeding cylinder 14, and the feeding shaft 18 will also drive the multiple mixing plates 20 to rotate together, and then the crushed bricks and concrete blocks are respectively put into the feeding hopper 1 on both sides. 5, the crushed stones are mixed evenly under the stirring of the rotating mixing plate 20, and the mixed crushed materials are introduced into the feeding tube 14 and rolled into the rotating spiral blades 19, so that the mixed crushed materials are rolled into the spiral blades 19 in turn and transported downward, which will not cause the mixed crushed materials to be layered up and down and the large and small particles to roll and fall in sequence when pouring. After the crushed materials are transported to the bottom of the feeding tube 14, they will be discharged through the feeding conduit 16 and enter the two docking semi-guide buckets 13, and mix with each other and enter the compaction tube 3. In this way, the crushed materials of bricks and concrete blocks can be uniformly mixed and transported into the compaction tube 3 in sequence, avoiding the situation that the crushed materials of different sizes fall in sequence due to the friction between each other during the direct pouring process, which affects the results of the compaction test; After the crushed materials of construction waste are loaded into the compaction cylinder 3, the U-shaped plate 11 and the lifting arc plate 12 are used to move and impact, so that the crushed materials in the compaction cylinder 3 are vibrated and compacted. Then, the hydraulic seat 2 is started to press the compaction seat 21 downward. The compaction seat 21 is pressed into the compaction cylinder 3 and vibrates and presses down to gradually compact the crushed materials in the compaction cylinder 3. After compaction once, a part of the crushed materials is refilled, and then the compaction seat 21 is pressed down to compact. After the crushed materials in the compaction cylinder 3 are compacted, the compaction seat 21 is moved downward. The compaction seat 21 is pressed down slowly from top to bottom, and at the same time, the micro air pump 22 is started to pass gas into the rubber ring 23, so that the rubber ring 23 is compressed and expanded. The rubber ring 23 will be pressed against the inner wall of the extension sleeve 6 and the compaction cylinder 3, so that the bottom of the compaction seat 21 is in a relatively sealed state during the downward pressing process. The air pressure below the compaction seat 21 and between the compacted crushed materials will gradually increase. Before pressing down, the electric push rod 25 is used to push the flat plate 26 out so that the bottom of the compaction seat 21 The air pressure sensor 24 in the storage groove can sense and detect the external air pressure. When the leveling plate 26 is pushed down, the two pillars 27 slide on the slide bar 28 and stretch and separate the tension spring 29. During the compaction process, the two pillars 27 dock with each other to support the leveling plate 26 to ensure the flatness of the leveling plate 26 and the bottom of the compaction seat 21. If the crushed materials in the compaction cylinder 3 are not completely compacted, as the air pressure continues to increase, the high-pressure gas will enter the gap between the crushed materials along the gap, causing the air pressure below the compaction seat 21 and between the compacted crushed materials to suddenly decrease during the overall increase, which is sensed by the air pressure sensor 24 and the signal is transmitted. In this way, after the compaction of the crushed materials is completed, the state of the rubber ring 23 and the leveling plate 26 on the compaction seat 21 can be changed to detect whether the compacted crushed materials are completely compacted, thereby avoiding the problem that the inside of the crushed materials is difficult to directly observe, and ensuring the reliability of the compaction test results.
