Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0037] Example 1: like Figure 1 and 2 As shown, this embodiment consists of a connecting frame 1, a compaction component 2, a coupling component 3, a lateral shifting component 4, and a paving component 5. The connecting frame 1 is used to connect with an excavator. The compaction component 2 is longitudinally connected to the connecting frame 1. The paving component 5 is laterally connected to the compaction component 2 via the coupling component 3. The compaction component 2 includes a compaction frame 21 and a compaction wheel 22 connected below the compaction frame 21. The top of the compaction frame 21 is connected to the connecting frame 1, and the sidewall is connected to the coupling component 3. The coupling component 3 includes a first coupling frame 31 and a second coupling frame 32. The first coupling... The first coupling frame 31 and the second coupling frame 32 are detachably connected. The first coupling frame 31 is connected to the side wall of the compaction frame 21. The top of the second coupling frame 32 is connected to the lateral shift component 4. The moving part of the lateral shift component 4 is connected to the paving component 5. In other embodiments, the lateral shift component 4 may not be provided, and the second coupling frame 32 is directly connected to the paving component 5. The paving component 5 includes a paving frame 51 and a scraper 52 installed on the paving frame 51. The scraper 52 generally includes two movable scrapers or one movable scraper and one fixed scraper.

[0038] Example 2: like Figure 1 and 2 As shown, this embodiment consists of a connecting frame 1, a compaction component 2, a coupling component 3, a lateral shifting component 4, and a paving component 5, combined with... Figure 3 and 4The connecting frame 1 includes two boom connecting rods 11, which connect the connecting frame 1 to the excavator boom and allow for swinging. The compaction assembly 2 is located directly below the connecting frame 1. The compaction assembly 2 includes a compaction frame 21, the top of which is fixedly connected to the connecting frame 1, and a compaction wheel 22 connected to its bottom. A vibrator 23 is also installed on the connecting frame 1, located inside the compaction wheel 22. The vibrator 23 drives an eccentric block via a vibration motor to vibrate the compaction wheel 22. A scraper 24 is also installed on the compaction frame 21, positioned near the compaction wheel 22 to scrape off road construction materials, such as asphalt, adhering to the compaction wheel 22. The first coupling frame 31 of the coupling assembly 3 is fixedly connected to the side of the compaction frame 21.

[0039] Combination Figure 5A and 5B The first coupling frame 31 includes mounting plates 311 on both sides. A handle 312 and a plug rod 313 are provided within the mounting plates 311. By controlling the plug rod 313 through the handle 312, the first coupling frame 31 and the second coupling frame 32 can be switched between fixed and detachable states. Specifically, the handle 312 is connected to the plug rod 313 via a connecting rod 314. One end of the connecting rod 314 is fixedly connected to a limit nut 316, and the other end is fixedly connected to a boss 318. A spring 315 is provided on the limit nut 316. Between the handle 312 and the boss 318, a sliding sleeve 317 is connected. The sliding sleeve 317 is located between the limiting nut 316 and the spring 315 and can slide relative to the connecting rod 314. When the handle 312 rotates, it drives the sliding sleeve 317 to compress the spring 315 and apply force to the boss 318. The front end of the boss 318 is rotatably connected to the insertion rod 313. The insertion rod 313 is located inside the sleeve 319, which is fixed to the mounting plate 311. Thus, the rotation of the handle 312 drives the insertion rod 313 to move up and down. Figure 6 The second coupling frame 32 includes a back plate 321, and side plates 322 extend outward from the four sides of the back plate 321. The space formed by the side plates 322 is used to accommodate the mounting plate 311 and to fit into it. The side plates 322 are provided with insertion holes 323 at the positions where they cooperate with the insertion rod 313. The insertion rod 313 can be inserted and removed in the insertion holes 323 to achieve quick installation and quick removal between the first coupling frame 31 and the second coupling frame 32.

[0040] Combination Figure 7The second coupling frame 32 is also equipped with a support leg 324 and a solenoid valve 325. The support leg 324 is used to control the height of the second coupling frame 32 from the ground, while the solenoid valve 325 is connected to the excavator's control console and hydraulic system, thereby controlling the movement of the first cylinder 541, the second cylinder 542, and the third cylinder 43 in the lateral shift assembly 4 and the paving assembly 5. The lateral shift assembly 4 is installed above the second coupling frame 32, with a fixed frame 41 fixedly connected to the second coupling frame 32. The lateral shift frame 42 is fitted inside the fixed frame 41. The third cylinder 43 is connected to the fixed frame 41 and drives the lateral shift frame 42 to translate relative to the fixed frame 41. A fixed frame limiting plate 411 is provided at the outlet end of the fixed frame 41, which cooperates with the lateral shift frame limiting plate 421 on the lateral shift frame 42 to limit the displacement distance of the lateral shift frame 42. A paving frame connecting shaft 422 is provided in the middle of the lateral shift frame 42. The paving frame 51 of the paving assembly 5 is rotatably mounted on the paving frame connecting shaft 422. Figure 8 The floating positioning lock 57 on the paving frame 51 and the locking groove 423 on the side shift frame 42 are used to control whether the paving frame 51 is in a rotatable state. When the paving frame 51 is in a horizontal state and the floating positioning lock 57 is inserted into the locking groove 423 and locked, the paving frame 51 cannot rotate to suit the requirements of straight paving. When the floating positioning lock 57 is pulled out from the locking groove 423, the paving frame 51 can swing left and right, thus suiting the requirements of sloping paving at turns.

[0041] A slide rail 53 is provided on the paving frame 51. A first scraper 521 and a second scraper 522 are slidably connected to the slide rail 53. A first hydraulic cylinder 541 drives the first scraper 521, and a second hydraulic cylinder 542 drives the second scraper 522. The first scraper 521 and the second scraper 522 have a scraper seat 524 and a scraper plate 525. The scraper seat 524 is set on the slide rail 53 and connected to the hydraulic cylinder. The scraper plate 525 is rotatably connected to the scraper seat 524. The angle formed between the scraper plate 525 and the scraper seat 524 is controlled by a telescopic rod 526. The two ends of the telescopic rod 526 are respectively connected to the scraper plate 525 and the scraper seat 524. The 24-rotatable connection allows adjustment of the angle between the scraper plate 525 and the scraper seat 524 by adjusting the length of the telescopic rod 526. A baffle 55 is also connected to the bottom of the paving frame 51 via a height adjustment rod 56. The height adjustment rod 56 is a screw structure; rotating the screw allows the baffle 55 to rise or fall relative to the paving frame 51. The baffle 55 is used for the initial paving of the road, ensuring that the height of the road construction material after paving by the scraper 52 and the baffle 55 meets the requirements before compaction. For example, if the height of the baffle 55 is adjusted to 1.3 times the actual construction requirements, the road construction material, after being compacted by the compaction wheel 22, will meet the actual construction requirements.

[0042] Example 3: The structure of this embodiment is basically the same as that of embodiment 2. The scraper plate 525 of the first scraper 521 and the scraper seat 524 are detachably connected. This detachment is achieved by pulling out the rotating pin between the scraper plate 525 and the scraper seat 524. When the required paving width is greater than the stroke of the first scraper 521 or the second scraper 522, the scraper plate 525 of the first scraper 521 and / or the second scraper 522 is disassembled, and a third scraper 523 is set at one or both ends of the paving frame 51. The third scraper 523 is rotatably connected to the paving frame 51, and a telescopic rod is provided between the third scraper 523 and the paving frame 51. The telescopic rod has the same structure and cooperation method as the telescopic rod 526 between the scraper plate 525 and the scraper seat 524.
