Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" used herein refer to the same directions as the drawings, and do not limit the structure.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.

In an embodiment, as shown in fig. 1, 2 and 3, the disc suction groove lifting mechanism for road cleaning equipment provided by the utility model comprises a support 1, wherein the support 1 is used for installing a plurality of disc suction grooves 2 at intervals, the support 1 is provided with a plurality of pairs of automatic lifting assemblies 3 which correspond to the disc suction grooves 2 one by one, each automatic lifting assembly 3 comprises an upper connecting plate 31 connected with the support 1 and a lower connecting plate 32 connected with the side surface of the disc suction groove 2, a guide 33 is arranged between the upper connecting plate 31 and the lower connecting plate 32, a spring 34 is sleeved outside the guide 33, the top surface and the bottom surface of the spring 34 are respectively connected with the upper connecting plate 31 and the lower connecting plate 32, one side of the support 1 is provided with a buffer pull piece 4, and the buffer pull piece 4 is used for being connected with road cleaning equipment. Wherein, automatic rising subassembly 3 can inhale the groove 2 with the disc and move along with the car under the drive of support 1, inhales the groove 2 ground rubbish and the sewage by the disc and inhales and carry out the suction. Under the condition that the disc suction groove 2 meets uneven ground, the spring 34 in the automatic lifting assembly 3 generates telescopic action, and meanwhile, the relative positions of the upper connecting plate 31 and the lower connecting plate 32 generate vertical change under the guide of the guide piece 33, so that the disc suction groove 2 can automatically adapt to different ground surfaces, and a better depth cleaning effect is obtained.

In order to improve the flexibility of the automatic lifting action of the disc suction groove 2, the guide part 33 provided by the utility model comprises a screw 331, the screw 331 comprises a threaded section and a smooth section, the threaded section is in threaded connection with a bolt hole arranged on the upper connecting plate 31, the threaded section is rotatably provided with an anti-drop nut 332 at a position close to the top of the threaded section, the smooth section is movably matched with a through hole arranged on the connecting plate, the bottom of the smooth section is fixedly provided with a limiting nut head 333, and one end of the lower connecting plate 32 is fixedly connected with the side surface of the disc suction groove 2. The limit nut head 333 limits the lowest position of the lower connecting plate 32, and the minimum length of the spring 34 subtracted from the actual length of the anti-drop nut 332 on the screw 331 from the limit nut head 333 is the maximum range of the up-and-down floating of the disc suction groove 2. When the disc suction groove 2 passes through the road surface with different ground conditions, the disc suction groove and the lower connecting plate 32 apply pressure or pulling force to the spring 34, the thread section of the screw 331 enables the disc suction groove and the upper connecting plate 31 to have stable relative relation, and the relative position of the lower connecting plate 32 and the screw 331 changes along with the change of the length of the spring 34, so that the purpose of automatic lifting is achieved.
