Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0022] A new type of double-roller laser paver, including a machine body. The machine body includes a chassis 1. A telescopic arm 11 is arranged on the upper surface of the chassis 1. A material distribution box 12 is installed on the surface of the telescopic arm 11. A laser receiver 13 is installed on the surface of the material distribution box 12. A scraper 14 is arranged on the surface of the material distribution box 12. By the telescopic movement of the telescopic arm 11, the material distribution box 12 and the scraper 14 can be driven to move. The setting of the laser receiver 13 can emit a laser beam onto the paving surface and can determine the height of the paving surface by measuring the reflected light of the laser beam. The setting of the scraper 14 can spread the material;

[0023] The surface of the chassis 1 is provided with an adjusting mechanism. The adjusting mechanism includes a fixing plate 2. The fixing plate 2 is fixedly connected to the upper surface of the material distribution box 12. A screw rod 25 is movably connected to the inner side of the fixing plate 2. A moving block 27 is threadedly connected to the surface of the screw rod 25. A connecting rod 28 is fixedly connected to the surface of the moving block 27. A scraper 14 is arranged on the surface of the connecting rod 28. By rotating the screw rod 25, the moving block 27 can be driven to move vertically. Further, the connecting rod 28 can drive the mounting rod 3 to move under the action of the moving block 27, so that the height of the scraper 14 can be adjusted, facilitating the flexible spreading of the material into different thicknesses by the scraper 14.

[0024] Further, the adjusting mechanism further includes a fixing block 21. The fixing block 21 is fixedly connected to the top end of the fixing plate 2. A rotating rod 22 is movably connected to the inner side of the fixing block 21. A first bevel gear 23 is fixedly connected to the surface of the rotating rod 22. A motor 24 is fixedly installed on the surface of the fixing block 21. The rotating rod 22 and the output end of the motor 24 are fixedly connected. A second bevel gear 26 is fixedly connected to the top end of the screw rod 25. A limiting block 29 is fixedly connected to the surface of the moving block 27. A limiting groove 210 is formed in the inner wall of the fixing plate 2. By rotating the rotating rod 22, the first bevel gear 23 can be driven to rotate. Further, the second bevel gear 26 can rotate under the action of the first bevel gear 23 and drive the two screw rods 25 to rotate simultaneously, making the transmission of the screw rod 25 more convenient, so that the lifting of the moving block 27 driving the scraper 14 can be realized.

[0025] Further, two groups of screw rods 25 are movably connected to the fixing plate 2, and two groups of moving blocks 27 are correspondingly connected to the screw rods 25. The moving blocks 27 move inside the fixing plate 2. Through the arrangement of the moving blocks 27, when the screw rods 25 rotate, the moving blocks 27 can drive the connecting rods 28 to move vertically under the action of the screw rods 25, so that the height of the scraper 14 can be adjusted during the spreading process.

[0026] Further, one end of the limiting block 29 is fixedly connected to the end of the moving block 27 away from the connecting rod 28, and the other end of the limiting block 29 is movably connected to the limiting groove 210. Through the cooperation of the limiting block 29 and the limiting groove 210, the moving block 27 can be limited, and the moving block 27 can be prevented from shifting under the action of the screw rod 25, facilitating the stable lifting of the moving block 27 driving the connecting rod 28.

[0027] Furthermore, a replacement mechanism is provided inside the connecting rod 28. The replacement mechanism includes an installation rod 3. The installation rod 3 is fixedly connected to the surface of the scraping plate 14. An installation groove 31 is formed inside the connecting rod 28. The installation rod 3 is movably connected to the installation groove 31. A plug rod 32 is movably connected inside the connecting rod 28. A slot 33 is formed on the surface of the installation rod 3. A pull rod 34 is fixedly connected to the surface of the plug rod 32. A spring 35 is fixedly connected to the surface of the pull rod 34. By moving the plug rod 32, it can be inserted into and separated from the slot 33, thereby fixing and releasing the fixing of the installation rod 3, making it more convenient to replace the scraping plate 14.

[0028] Furthermore, two groups of installation rods 3 are fixedly connected to the scraping plate 14, two groups of plug rods 32 are movably connected to the connecting rod 28, one end of the spring 35 is fixedly connected to the connecting rod 28, and the other end of the spring 35 is fixedly connected to the pull rod 34. Through the arrangement of the spring 35, the pull rod 34 can be reset, and then the pull rod 34 can drive the plug rod 32 to be inserted into the slot 33, making it more convenient to fix the scraping plate 14.

[0029] Working principle: When in use, the motor 24 is electrically connected by an external power supply. The staff starts the motor 24 by pressing the switch. The motor 24 runs to drive the rotating rod 22 to rotate. The first conical tooth 23 will rotate under the action of the rotating rod 22. Then, the second conical tooth 26 will rotate under the action of the first conical tooth 23 and drive the screw rod 25 to rotate. The moving block 27 is limited by the limiting block 29 and the limiting groove 210, and will move up and down inside the fixing plate 2 under the action of the screw rod 25. Then, the limiting block 29 slides on the surface of the limiting groove 210, so that the connecting rod 28 can drive the scraping plate 14 to move vertically, and the height of the scraping plate 14 can be adjusted;

[0030] By pulling the pull rod 34, the plug rod 32 will move inside the connecting rod 28 under the action of the pull rod 34 and separate from the slot 33. At this time, the spring 35 is in a stretched state, and the fixing of the installation rod 3 can be released. Thus, the installation rod 3 can be pulled out of the installation groove 31, and the scraping plate 14 can be removed for replacement; when the scraping plate 14 needs to be reinstalled, insert the installation rod 3 into the inside of the installation groove 31, and then release the pull rod 34. The pull rod 34 will reset under the elastic return action of the spring 35, and then the plug rod 32 and the slot 33 can be inserted, and the fixing of the installation rod 3 can be achieved.

[0031] The above are only the preferred embodiments of the present utility model and do not impose any form of limitation on the present utility model. Any ordinary technician in the industry can smoothly implement the present utility model according to what is shown in the accompanying drawings of the specification and the above. However, any minor changes, modifications, and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are equivalent embodiments of the present utility model. At the same time, any changes, modifications, and equivalent variations made to the above embodiments based on the essential technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
