Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the device for adjusting the height of the driving axle of the sweeper comprises a U-shaped bracket 1, two side plates 101 of the bracket 1 are provided with first U-shaped notches 2 which are symmetrically arranged, two sides of each first U-shaped notch 2 are provided with adjusting holes 3 which are symmetrically arranged, and each adjusting hole 3 is a vertically-arranged strip hole. The drive axle 4 is arranged in the first U-shaped notch 2, the outer sides of two side plates 101 of the support 1 are respectively provided with a fixing plate 5, the fixing plate 5 is provided with a fixing hole 6, the fixing plate 5 and the side plates 101 penetrate through the fixing hole 6 and the adjusting hole 3 through bolts (not shown in the figure) to be connected, the fixing plate 5 is provided with a second U-shaped notch 7, the second U-shaped notch 7 is welded with the drive axle 4, and two sides of the second U-shaped notch 7 are respectively provided with two fixing holes 6 which are vertically arranged. Be equipped with on the bottom plate 102 of support 1 and have an internal screw thread solid fixed cylinder 8, gu fixed cylinder 8 threaded connection adjusts pole 9, it is equipped with 3 adjusting nut 10 that equidistant setting is equipped with to adjust the pole 9 periphery, adjust pole 9 top fixed connection lifter 11, lifter 11 top swing joint is in the recess that transaxle 4 bottoms set up, the height-adjusting of adjusting pole 9 is 80 mm.
