DETAILED DESCRIPTION

[0017] The road gravel arrangement device of the present utility model will be described below in conjunction with the accompanying drawings.

[0018] In the first embodiment of the present application, Figures 1 to 3As shown, the road gravel finishing device (hereinafter referred to as "this patent") includes a bracket 1, a transition bracket 2, a fastener 2.1, a main bracket 3, a fastener 2.1, a limit plate 3.2, a motor cover 4, a material blocking cover 5, a spray pipe 6, a nozzle 1 6.1, a nozzle 2 6.2, a crushing wheel 1 7, a knife tooth 7.1, a crushing wheel 2 8, a scraper plate 9, a connecting shaft 9.1, a torsion spring 9.2, a pressure plate 10, a rotating shaft 11, a driving wheel 12, a motor 13, a belt 14, a driven wheel 15, a transmission shaft 16 and a transmission shaft 2 17. The excavator boom is connected to the bracket 1, the bracket 1 is connected to the transition bracket 2 and fastened with a fastener 2.1, the pressure plate 10 on the inner side of the transition bracket 2 is fixedly connected to the rotating shaft 11 at the center of the main bracket 3, the transition bracket 2 fixes the main bracket 3 by fasteners 2 3.1 evenly distributed on the edge, and is connected to the excavator through the bracket 1. The transition bracket 2 is connected to the main bracket 3 through the rotating shaft 11 and the pressure plate 10. The main bracket 3 can be rotated to a certain angle through the rotating shaft 11 and the pressure plate 10 to adapt to more working environments. After being rotated into place, the transition bracket 2 and the main bracket 3 are fixed by the circumferentially evenly distributed fasteners 2 3.1. Rotating to different angles can adapt to different working environments. A motor 13 is fixedly installed in the middle of the main bracket 3, and a driving wheel 12 is installed on the output shaft of the motor 13. The driving wheel 12 is connected to the driven wheel 15 installed at the end of the main bracket 3 through a belt 14. The two sides of the driven wheel 15 are fixedly connected to the transmission shaft 1 16 and the transmission shaft 2 17 respectively. The transmission shaft 1 16 is connected to the crushing wheel 1 7, and the transmission shaft 2 17 is connected to the crushing wheel 2 8. The surfaces of the crushing wheels 1 7 and 2 8 have blade teeth 7.1 arranged at equal intervals. The material blocking cover 5 is fixedly installed on the upper part of the crushing wheel 1 7 and the crushing wheel 2 8 to prevent the rock debris splashed during the crushing process from harming the operators and equipment. The spray pipe 6 is fixedly installed on the front end of the upper part of the material blocking cover 5 through a bracket. The spray head 1 6.1 and the spray head 2 6.2 are evenly distributed in the radial direction of the spray pipe 6. The spray head 2 6.2 faces the crushing wheel, and the water sprayed by the spray head 2 6.2 is fan-shaped, which can completely cover the length of the crushing wheel 1 7 and the crushing wheel 2 8. The knife teeth 7.1 are cooled down, and the smoke and dust in the crushing process are suppressed at the same time. The spray head 1 6.1 sprays water obliquely upward, and the water appears in the form of a mist, which suppresses the smoke and dust on the outside during the crushing process.

[0019] A small mechanical road gravel crushing device with application number 202111202114.0 that can perform multi-directional friction crushing (hereinafter referred to as "this patent") is mainly used to deal with broken concrete and small stones generated during urban demolition. It is less efficient when dealing with large hard rocks buried in hardened earth roads, is not very convenient to use, and has a relatively complex overall structure and high cost, and cannot help construction units reduce costs and improve efficiency. The structure of this patent is relatively simple. It only needs to be installed on the arm of an excavator used on a large scale on the construction site to start gravel crushing operations. The cost is extremely low. At the same time, with the help of special crushing wheel 1 7 and crushing wheel 2 8 and the teeth 7.1 thereon, hard rocks can be crushed more effectively, which can effectively improve work efficiency.

[0020] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 3 and Figure 4 As shown, the lower surface of the main support 3 is connected to the scraper plate 9 through a connecting shaft 9.1 and a torsion spring 9.2. A limit plate 3.2 is fixedly installed on the surface of the main support 3. The limit plate 3.2 is located on the side of the scraper plate 9 facing the front end of the main support 3. The scraper plate 9 can rotate, and a limit plate 3.2 is welded on the main support 3 in front to limit the forward flipping of the scraper plate 9. A torsion spring 9.2 is installed on the connecting shaft 9.1, and the scraper plate 9 can automatically reset after flipping backward. When debris splashes backward during the rock crushing process, the scraper plate 9 can block and slow it down.

[0021] In order to further optimize the working efficiency of the present application and provide protection for the motor 13, the motor 13 is equipped with a motor cover 4. In order to further improve the working efficiency of the scraper plate 9, the lower edge of the scraper plate 9 is provided with saw teeth. When the crushing is completed, the excavator uses the scraper plate 9 to scrape backwards to level the ground, and the front limit plate 3.2 can prevent the scraper plate 9 from flipping forward during the scraping process.

[0022] When the utility model is in use, the specific operations are as follows:

[0023] When in use, first remove the bucket of the excavator, then connect the bracket 1 to the excavator arm, then remove the fastener 2 3.1, let the main support 3 adjust the angle of the main support 3 with the pressure plate 10 and the rotating shaft 11 as the center, then fix it with the fastener 2 3.1, and then turn on the motor 13. The driving wheel 12 of the motor 13 drives the belt 14, the driven wheel 15, the transmission shaft 1 16 and the transmission shaft 2 17 to drive the crushing wheel 1 7 and the crushing wheel 2 8 to rotate. The rotating crushing wheel 1 7 and the crushing wheel 2 8 drive the cutter teeth 7.1 thereon to crush the rock. When the crushing is completed, the excavator uses the scraper plate 9 to scrape backwards to level the ground.

[0024] In summary, the road gravel finishing device of the embodiment of the utility model, by replacing the patent with the excavator arm, directly breaks the rocks buried in the road surface by the crushing wheel 1 7 and the crushing wheel 2 8 driven by the motor 13, can quickly process the protruding rocks and gravel on the road surface at a very low cost, and can effectively improve the road construction efficiency and maintenance-free time.
