Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Specific embodiment one:

[0027] Please refer to Figures 1-6As shown, the utility model is a kind of side brush multi-stage telescopic structure of sweeper, including pivot connecting piece 1, support frame 2, upper support rod 3, lower support rod 4, lower pressure oil cylinder 5 and outer swing oil cylinder 10.Support frame 2 both ends and upper support rod 3 both ends are respectively installed between pivot connecting piece 1 and support frame 2 by hinged seat hinged connection, and upper support rod 3 and lower support rod 4 are parallelly arranged.Lower pressure oil cylinder 5 fixed end is installed on pivot connecting piece 1 by hinged seat hinged connection.Lower pressure oil cylinder 5 telescopic end is installed on support frame 2 by hinged seat hinged connection.Sweeper's sweep disc assembly 6 is located on support frame 2.It further includes telescopic arm assembly.Lower pressure oil cylinder 5 extends when sweep disc assembly 6 sweeps disc works, reaches specified height and just contacts with road surface.

[0028] Telescopic arm assembly includes cantilever fixed seat 7 connected with sweeper chassis, telescopic cantilever 8, telescopic oil cylinder 9.Telescopic cantilever 8 and cantilever fixed seat 7 linearly slide fit, and telescopic oil cylinder 9 fixed end is installed on cantilever fixed seat 7 by hinged seat hinged connection.Telescopic oil cylinder 9 telescopic end is installed on telescopic cantilever 8 by hinged seat installation.Outer swing oil cylinder 10 fixed end is installed on telescopic cantilever 8 by hinged seat hinged connection.Outer swing oil cylinder 10 telescopic end is installed on pivot connecting piece 1 by hinged seat hinged connection.Among them, cantilever fixed seat 7 includes cantilever connecting seat plate 71 connected with sweeper chassis.Rectangular steel column 72 is vertically fixed on cantilever connecting seat plate 71.The linear guide 73 along its length direction is installed on the upper surface of rectangular steel column 72.Among them, telescopic cantilever 8 includes rectangular square tube 81.A plurality of guide sliding blocks 82 matched with linear guide 73 are installed on the inner top surface of rectangular square tube 81.Polytetrafluoroethylene plate 83 is symmetrically installed on the relative inner side wall of rectangular square tube 81.Sealing plate 84 is fixed on the outer side end surface of rectangular square tube 81.The mounting seat plate 85 for installing outer swing oil cylinder 10 is fixed on the lower surface of rectangular square tube 81.The connecting seat plate 86 matched with pivot connecting piece 1 is fixed on the outer side end lower surface of rectangular square tube 81.Among them, three triangular rib plates 74 are fixed between the two side surfaces and bottom surface of rectangular steel column 72 and cantilever connecting seat plate 71.Rectangular notch 87 matched with triangular rib plate 74 is formed on the two side walls and bottom wall of inner side end of rectangular square tube 81.Telescopic oil cylinder 9 is in the state of contraction when sweeper is in the state of conventional cleaning, and cantilever fixed seat 7 and telescopic cantilever 8 are in the state of contraction.

[0029] Under the conventional cleaning width, outer swing oil cylinder 10 is retracted first, drives pivot connecting piece 1, makes sweep disc assembly 6 swing to the body, reaches conventional cleaning width, telescopic oil cylinder 9 does not work at this time, and the cleaning width is 3.5m.When it is needed to expand the cleaning width, telescopic oil cylinder 9 acts, telescopic cantilever 8 is extended outward under the support of linear guide 73, drives the sweep disc of sweep disc assembly 6 to extend outward, thereby increasing the cleaning width.Telescopic adjustment of telescopic oil cylinder 9 to telescopic cantilever 8 is stepless adjustment, and stepless adjustment of 3.5-4.1 can be realized. Specific embodiment two

[0031] As Figure 3 And Figure 7 As shown in the figure, on the basis of embodiment one, the brush is an important working part of the sweeper truck, and the main materials are steel wire and plastic. The steel wire will generate sparks when rubbing against the ground during the sweeping process. In actual application, the materials are mainly selected according to the specific working conditions. The plastic brush is relatively more used. The wear resistance of plastic is not as good as that of steel wire, so after working for a period of time, the brush is worn and does not contact the ground, greatly reducing the sweeping effect. In order to solve this problem, a screw block mechanism 11 is installed on the support frame 2; a motor seat 12 for installing the sweeping disc assembly 6 is installed on the sliding seat of the screw block mechanism 11. The contact degree between the brush in the sweeping disc assembly 6 and the ground is adjusted by the screw block mechanism 11 without adjusting the above multi-stage telescopic structure.

[0032] The screw block mechanism 11 includes a fixed bottom plate, a screw rod, a sliding seat, a second linear guide rail, a hand wheel, a fixed side support, and a supporting side support. The fixed bottom plate is used to install the second linear guide rail, the fixed side support, and the supporting side support. The sliding seat is installed on the screw rod, the screw rod is connected with the fixed side support and the supporting side support, and the hand wheel is fixed at one end of the screw rod. The hand wheel drives the screw rod to rotate, and the sliding seat moves up and down on the screw rod. The sliding seat and the second sliding block installed on the second linear guide rail are fixed with the motor seat 12 at the same time, thereby driving the motor seat 12 to move. When the brush of the sweeping disc assembly 6 is worn and cannot meet the working conditions, the brush height adjustment can be realized through the structure, so that the brush is lowered to a degree that can meet the working conditions. At the same time, the structure can realize self-locking to prevent the reaction force of the ground from causing the brush to rise back.
