Description

Technical Field

[0001] This utility model relates to the field of roadbed construction technology, and in particular to a roadbed construction compaction device. Background Technology

[0002] The construction process of roadbed engineering involves the use of various mechanical equipment, including but not limited to earthmoving and transportation machinery (such as bulldozers, scrapers, and graders), excavating and loading machinery (such as excavators and loaders), construction vehicles, and compaction machinery. When the construction steps require road compaction, specialized rolling devices are used to accomplish this task.

[0003] For example, a roadbed construction compaction device with publication (announcement) number CN216919903U includes a compaction device and a compaction wheel. The compaction wheel is fixedly connected to the front of the compaction device. A fixed box is fixedly connected to the left side of the compaction wheel. A controller is movably installed on the rear side of the top of the fixed box. A transmission box located in front of the controller is movably installed on the top of the fixed box.

[0004] In summary, the following technical problems exist in the prior art: In the process of using the above-mentioned prior art and other typical prior art, the positions of the scraper and the compaction roller of the compaction device are often fixed, which causes the scraper and the compaction roller to continue to rub against each other even when not in operation, which greatly reduces the service life of the scraper. Therefore, we propose a roadbed construction compaction device. Utility Model Content

The hydraulic rod 4 is fixed to both ends of the top of the frame 2. The output end of the hydraulic rod 4 is fixed to the guide shaft 5. The top of the guide shaft 5 is rotatably connected to the connecting rod 6. A transmission assembly is mounted between the connecting rod 6 and the frame 2. The hydraulic rod 4 is an existing product of the HY-A, HY-B, and HY-C series.

[0027] The transmission assembly includes a double-bent rod 7, an L-shaped bracket 8, and a scraper 9. One end of each connecting rod 6 is rotatably connected to a double-bent rod 7, and the bend of each double-bent rod 7 is rotatably connected to an L-shaped bracket 8. The bottom of the L-shaped bracket 8 is fixed to the frame 2. One end of each of the two double-bent rods 7 is equipped with a scraper 9. The scraper 9 is parallel to the rolling roller 3, and the bottom of the scraper 9 has an inclined surface, which is parallel to the rolling roller 3.

[0028] Example 2

[0029] Further optimizations to Example 1, specifically, such as... Figure 2-4 As shown, an installation mechanism is assembled between the double-bent rod 7 and the scraper 9. The installation mechanism is used to connect the double-bent rod 7 and the scraper 9.

[0030] The installation mechanism includes a plug-in rod 10, a movable groove 11, an anti-detachment strip 12, a push rod 13, an annular groove 14, and auxiliary components. The plug-in rod 10 is fixed to the inner side of one end of the double-bent rod 7. Movable grooves 11 are provided on both sides of the plug-in rod 10. The anti-detachment strip 12 is rotatably connected to the inner side of the movable grooves 11 by pins. The push rod 13 is slidably connected to one end of the plug-in rod 10. The push rod 13 is clearance-fitted with the inner side of the double-bent rod 7. An annular groove 14 is provided on the outer side of the push rod 13. An auxiliary component is assembled between the annular groove 14 and the scraper 9. An inner frame opening is provided on the double-bent rod 7 near the plug-in rod 10. The inner frame opening is clearance-fitted with the push rod 13 to protect the end of the push rod 13 and prevent the end of the push rod 13 from being accidentally bumped or squeezed.

[0031] The auxiliary components include toothed blocks 15, release grooves 16, guide posts 17, connecting springs 18, inner grooves 19, and mating grooves 20. Toothed blocks 15 are slidably connected to both sides of the annular groove 14. The toothed blocks 15 are fixed to the anti-detachment strip 12. A release groove 16 is provided at one end of the inner side of the insertion rod 10. A guide post 17 corresponding to the position of the release groove 16 is fixed at one end of the push rod 13. The guide post 17 is slidably connected to the release groove 16. A connecting spring 18 is sleeved on the outer side of the guide post 17. One end of the connecting spring 18 is fixed to the push rod 13, and the other end is fixed to the inner side of the insertion rod 10. Both ends of the scraper 9 have inner grooves 19 corresponding to the positions of the insertion rod 10. The groove 19 is slidably connected to the plug rod 10. Both sides of the inner groove 19 are provided with mating grooves 20 corresponding to the position of the anti-detachment strip 12. The mating grooves 20 and the anti-detachment strip 12 are sized to fit. When the scraper 9 needs to be disassembled, push the push rod 13, so that the push rod 13 pushes the toothed block 15 through the annular groove 14 to move, thereby causing the toothed block 15 to drive the anti-detachment strip 12 to rotate. The anti-detachment strip 12 gradually separates from the mating groove 20. At the same time, the push rod 13 compresses the connecting spring 18 to retract, so that the guide post 17 is inserted into the release groove 16 until the anti-detachment strip 12 retracts into the movable strip groove 11, releasing the limit between the scraper 9 and the plug rod 10. Then the scraper 9 and the plug rod 10 can be separated.

[0032] The toothed block 15 has an arc surface at its end, which is slidably connected to the inner side of the annular groove 14. The toothed block 15 and the annular groove 14 are in clearance fit. When the push rod 13 moves the annular groove 14, the toothed block 15 is moved by pushing or pulling through the guiding effect of the arc surface.

[0033] In summary:

[0034] This utility model addresses the technical problem that, in the use of existing technologies and other typical prior art, the positions of the scraper and the compaction roller in the compaction device are often fixed, causing continuous friction between the scraper and the compaction roller even when not in operation, thus greatly reducing the service life of the scraper; the present invention adopts the technical solutions of the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0035] When the roller 3 is not in operation, the hydraulic rod 4 is activated. The output end of the hydraulic rod 4 pulls the guide shaft 5 and the connecting rod 6 downward. Because the guide shaft 5 is rotatably connected to the connecting rod 6, the connecting rod 6 is rotatably connected to the double-bent rod 7, and the double-bent rod 7 is rotatably connected to the L-shaped bracket 8, the double-bent rod 7 can drive the plug rod 10 and the scraper 9 to rotate until the scraper 9 no longer contacts the roller 3, preventing the scraper 9 from wearing out during the operation of the roller 3 when the roller 3 is not in operation.

[0036] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0037] 1. Through the structural design of the scraping mechanism, this utility model makes it easy to scrape off the soil adhering to the surface of the roller 3. At the same time, it can lift the scraper 9 when the roller 1 is not in operation, so that the scraper 9 does not come into contact with the roller 3, thereby improving the service life of the scraper 9.

[0038] 2. Through the structural design of the installation mechanism, this utility model makes it easy to disassemble and assemble the scraper 9 when it is severely worn in the later stages, resulting in good performance.
