[0024] Please see Figure 1-6This utility model provides a technical solution: a municipal road maintenance device, including a device body 1, a support plate 2 fixedly connected to the top of the device body 1, a push handle 29 fixedly connected to the top of the device body 1 for pushing, two fixing blocks 5 fixedly connected to the front side of the support plate 2, each of the two fixing blocks 5 having a slot 9 for insertion, a motor slot 7 for placing a motor on the front side of the support plate 2, a placement slot 3 for placing a device on the inside of the support plate 2, a rotating shaft 6 rotatably connected to the inner wall of the placement slot 3, a support frame 4 rotatably connected to the surface of the rotating shaft 6, a fixing plate 8 provided on the front side of the support plate 2, a first sliding groove 12 provided inside the fixing plate 8, and a sliding connection inside the first sliding groove 12. A first sliding rod 11 is provided for support. A first spring 14 is fixedly connected to the side of the first sliding rod 11 away from the first sliding groove 12. The side of the first spring 14 away from the first sliding rod 11 is fixedly connected to the inner wall of the first sliding groove 12. A first gear groove 16 is provided inside the fixed plate 8. A first gear 15 is provided inside the first gear groove 16. A rotating rod 17 is fixedly connected to the front side of the first gear 15. One end of the rotating rod 17 rotates through the interior of the fixed plate 8 and extends to the outside of the fixed plate 8. The first gear 15 is connected to the first sliding rod 11 by tooth meshing. The interior of the first gear groove 16 is connected to the first sliding rod 11 by tooth meshing. The interiors of the first slide groove 12 are interconnected. A second slide groove 18 is formed inside the fixing plate 8. A second slide rod 10 is slidably connected inside the second slide groove 18. A second spring 13 is fixedly connected to the side of the second slide rod 10 away from the second slide groove 18. The side of the second spring 13 away from the second slide rod 10 is fixedly connected to the inner wall of the second slide groove 18. The second slide rod 10 is connected to the first gear 15 through tooth meshing. Rotation of the first gear 15 can simultaneously drive the sliding of the first slide rod 11 and the second slide rod 10. The surfaces of the second slide rod 10 and the first slide rod 11 are slidably connected to the interiors of the slots 9. The first slide rod 11 and the second slide rod 10 are respectively connected to the slots 9 on the two fixing blocks 5. The internal sliding connection allows the first slide rod 11 and the second slide rod 10 to slide within the first slide groove 12 and the second slide groove 18 when the operator wants the support frame 4 to be horizontal. This is achieved by rotating the rotating rod 17, which compresses the first spring 14 and the second spring 13, causing the first slide rod 11 and the second slide rod 10 to slide out of the slot 9, allowing the support frame 4 to be placed horizontally. Then, releasing the rotating rod 17 causes the first spring 14 and the second spring 13 to reset and push the first slide rod 11 and the second slide rod 10 into the slot 9. This ensures that the support frame 4 is placed horizontally and is also fixed to prevent shaking when the equipment body vibrates. However, the support frame 4 can also be fixed by this operation when it is placed in the placement slot.

[0025] Furthermore, a motor 28 is fixedly connected to the left side of the support frame 4. A transmission groove 19 is formed inside the support frame 4. The output end of the motor 28 rotatably passes through one side of the support frame 4 and extends into the transmission groove 19. A disc 20 is fixedly connected to the output end of the motor 28. A connecting rod 21 for transmission is rotatably connected to the right side of the disc 20. A third sliding rod 22 is rotatably connected to the side of the connecting rod 21 away from the disc 20. A third sliding groove 23 is formed inside the support frame 4. The interior of the third sliding groove 23 is slidably connected to the surface of the third sliding rod 22. The interior of the third sliding groove 23 is interconnected with the interior of the transmission groove 19. A second gear groove 24 is formed inside the support frame 4. A second gear 25 is rotatably connected inside the second gear groove 24. The interior of the second gear groove 24 is interconnected with the interior of the third sliding groove 23. The second gear and the third sliding rod 22 are connected by tooth meshing. A rotating shaft 26 is fixedly connected to the right side of the second gear 25. One end of the rotating shaft 26 rotatably passes through the interior of the support frame 4 and extends into the support frame. The outer rotating shaft 26 of the support frame 4 rotates through the interior of the second gear groove 24 and extends to the exterior of the support frame 4. A water spray plate 27 is fixedly connected to the surface of the rotating shaft 26. The interior of the water spray plate 27 is hollow and has nozzles. The water spray plate 27 is connected to the pump body of the equipment body 1 through a pipe, so that the equipment body 1 can deliver water to the interior of the water spray plate 27 through the pump body and spray it out through the nozzles on the water spray plate 27. When the staff wants to clean the dust, when the motor 28 is started, the output end of the motor 28 drives the disc 20 to rotate. The connecting rod 21 on the surface of the disc 20 begins to make a circular motion. Because the other side of the connecting rod is rotatably connected to the third slide rod 22, the third slide rod 22 can reciprocate in the third slide groove 23, which drives the rotation of the second gear 25. The second gear 25 also drives the water spray plate 27 to make a semi-circular arc motion through the rotating shaft 26, so that the water spray coverage is uniform and wide, thereby improving the irrigation or cleaning effect.

[0026] Working principle: For this type of municipal road maintenance device, when the worker wants the horizontal support frame 4, they can rotate the rotating rod 17 to make the first sliding rod 11 and the second sliding rod 10 slide within the first sliding groove 12 and the second sliding groove 18. At the same time, the first spring 14 and the second spring 13 are compressed, causing the first sliding rod 11 and the second sliding rod 10 to slide out of the slot 9, allowing the support frame 4 to be placed horizontally. Then, releasing the rotating rod 17 causes the first spring 14 and the second spring 13 to return to their original positions, pushing the first sliding rod 11 and the second sliding rod 10 back into the slot 9. This ensures that the support frame 4 is placed horizontally and is also fixed in place to prevent equipment from malfunctioning. The main body shakes when it vibrates, but the support frame 4 can also be fixed by this operation when it is placed in the placement slot. When the staff wants to clean the dust, when the motor 28 is started, the output end of the motor 28 drives the disc 20 to rotate. The connecting rod 21 on the surface of the disc 20 begins to make a circular motion. Because the other side of the connecting rod is connected to the third slide rod 22, the third slide rod 22 can reciprocate in the third slide groove 23. At the same time, it drives the rotation of the second gear 25. The second gear 25 also drives the water spray plate 27 to make a semi-circular motion through the rotating shaft, so that the water spray coverage is uniform and wide, thereby improving the irrigation or cleaning effect.
