Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0027] See also Figure 1-Figure 5 The utility model provides a highway maintenance and cleaning equipment, including a fixed frame 1 installed on a dust suction sweeper, the fixed frame 1 is equipped with a mounting frame 2, a vertically extending shaft rod 3 is rotatably mounted on the mounting frame 2, a first driving mechanism 5 is provided on the mounting frame 2 for driving the shaft rod 3 to rotate, a disc 4 is installed at the bottom end of the shaft rod 3, and a cleaning brush head 41 is evenly distributed on the lower surface of the disc 4, a dust suction hood 6 with an opening at the bottom is fixed to the lower surface of the mounting frame 2, the dust suction hood 6 is provided with a vertical portion 61 above and a trumpet-shaped portion 62 with a small upper portion and a large lower portion below, the vertical portion 61 is arranged around the shaft rod 3, and the trumpet-shaped portion 62 is arranged around the disk 4, a negative pressure dust suction space 01 is formed between the inner wall of the vertical portion 61 and the shaft rod 3, and between the inner wall of the trumpet-shaped portion 62 and the disk 4, the vertical portion 61 is connected with a dust suction pipe 63 communicating with the negative pressure dust suction space 01, and the end of the dust suction pipe 63 is connected with the dust collection bin on the dust suction sweeper.
[0028] When the cleaning device is used to clean the road surface, the first driving mechanism 5 drives the shaft 3 and the disc 4 to rotate, and the cleaning brush head 41 on the disc 4 can clean the garbage and dirt on the road surface. The negative pressure pump in the dust collection bin on the vacuum road sweeper works to generate negative pressure, and the cleaned dust and garbage and dirt can be sucked into the negative pressure dust collection space 01, and sucked into the dust collection bin through the dust collection pipe 63, so as to collect dust, garbage and dirt. Since the dust hood 6 is arranged around the shaft 3 and the disc 4, when the disc 4 rotates and the cleaning brush head 41 is used to clean and radiate the garbage and dirt to the periphery, the lower end of the dust hood 6 is circumferentially covered on the movement path of the garbage and dirt, and when the garbage and dirt move to the periphery, it can be sucked into the negative pressure dust collection space 01 by the negative pressure, so as to avoid the leakage of garbage and dirt, and improve the cleaning effect of the road surface.
[0029] Specifically, the first driving mechanism 5 includes a first driving motor 51, a main gear 52, a connecting shaft 53 and a driven gear 54. The first driving motor 51 is fixed on the mounting frame 2, the main gear 52 is fixed on the output shaft of the first driving motor 51, the connecting shaft 53 is fixed on the top of the shaft rod 3, and the driven gear 54 is fixed on the connecting shaft 53 and meshes with the main gear 52. When the first driving motor 51 works, its output shaft drives the main gear 52 to rotate, and the rotating main gear 52 meshes and drives the driven gear 54 and drives the connecting shaft 53 and the shaft rod 3 to rotate, and then the connecting shaft 53 drives the disc 4 to rotate, providing drive for the cleaning action.
[0030] Specifically, the bottom of the shaft rod 3 is provided with a sliding hole 31 extending vertically upward, and a sliding rod 32 is slidably installed in the sliding hole 31, and the bottom end of the sliding rod 32 extends to the bottom of the shaft rod 3, and the disc 4 is fixed on the bottom end of the sliding rod 32. A vertically extending spring 33 is provided in the sliding hole 31, one end of the spring 33 is fixed to the top wall in the sliding hole 31, and the other end is fixed to the end surface of the sliding rod 32 located in the sliding hole 31. When cleaning on a flat road surface, the disc 4 is located above the road surface, and the cleaning brush head 41 contacts the road surface to ensure normal cleaning. When encountering bumpy sections, when the road surface is convex, the disc 4 is pressed to push the sliding rod 32 to move upward, and the spring 33 is compressed and stored. When the road surface returns to being flat or concave, the elastic force of the spring 33 pushes the sliding rod 32 and the disc 4 to move downward, thereby playing a buffering effect and preventing the disc 4 from being damaged.
[0031] Specifically, the cross-section of the slide rod 32 is rectangular, and the cross-section of the slide hole 31 is a rectangular shape that matches the slide rod 32. The cross-sections of the slide rod 32 and the slide hole 31 are set to be rectangular shapes that match each other, which can limit the slide rod 32 and prevent the slide rod 32 and the slide hole 31 from having the ability to rotate relative to each other, thereby ensuring that when the shaft rod 3 rotates, it can drive the slide rod 32 and the disk 4 to rotate normally.
[0032] During long-term operation, some dust, garbage or dirt will adhere to the inner walls of the vertical portion 61 and the trumpet-shaped portion 62, which will not only affect the circulation effect of the negative pressure airflow, but in severe cases may even cause blockage and make it impossible to perform normal negative pressure suction. In order to solve this problem, the present application has made the following improvements.
[0033] A connecting arm 34 is fixed to the side surface of the shaft 3, and a scraper 35 is fixed to the end of the connecting arm 34. The scraper 35 slides and fits against the inner walls of the vertical portion 61 and the trumpet-shaped portion 62 respectively. During the rotation of the shaft 3, the fixed connection of the connecting arm 34 can drive the scraper 35 to rotate synchronously, and the scraper 35 slides and fits against the inner walls of the vertical portion 61 and the trumpet-shaped portion 62, so that during the rotation, the dust, garbage and dirt attached to the inner walls of the vertical portion 61 and the trumpet-shaped portion 62 can be scraped off, and after being scraped off, they are sucked into the dust collection bin by negative pressure, thereby ensuring the normal circulation of the negative pressure airflow and ensuring the normal negative pressure suction.
[0034] Specifically, the fixing frame 1 is provided with a second driving mechanism 7, and the second driving mechanism 7 is used to drive the mounting frame 2 to perform translation adjustment.
[0035] Specifically, the second driving mechanism 7 includes a guide seat 71, a threaded rod 72, a second driving motor 73 and a nut seat 74. The guide seat 71 is fixed to the side of the fixing frame 1. A guide groove 711 is provided on the guide seat 71. The threaded rod 72 is rotatably installed in the guide groove 711. The second driving motor 73 is fixed to one side of the guide seat 71, and the output shaft is fixedly connected to one end of the threaded rod 72. The nut seat 74 is limitedly slidably installed in the guide groove 711 and is threadedly mounted on the threaded rod 72. The mounting frame 2 is fixedly installed on the end surface of the nut seat 74. The threaded rod 72 is driven to rotate by the operation of the second driving motor 73. The rotating threaded rod 72 can threadably drive the nut seat 74 to slide left and right in the guide groove 711, thereby driving the mounting frame 2 to adjust left and right to achieve adjustment of the cleaning and suction range, which is highly practical.
[0036] Specifically, fixing feet 11 are fixed on both sides of the fixing frame 1, and through sockets 12 are respectively provided on the fixing feet 11, and fastening bolts 13 are respectively inserted into the sockets 12. By screwing the fastening bolts 13 into the fastening screw holes on the dust suction sweeper, the fixing frame 1 can be fixed on the dust suction sweeper to achieve the installation of the entire equipment. At the same time, the fastening method of the fastening bolts 13 makes the equipment detachable, which is convenient for disassembly, maintenance and repair.
[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
