Description

Technical Field

[0001] The utility model relates to the technical field of sweepers, and in particular to an electric lifting device for a suction nozzle of a sweeper. Background Art

[0002] A street sweeper is a mobile cleaning equipment mainly used in urban roads, parking lots, bridges, tunnels and other places. It can remove debris such as garbage, dust, fallen leaves and other debris on the ground to keep the environment clean. A street sweeper is usually composed of a cab, a power system, a cleaning system (such as a sweeping brush and a suction nozzle, etc.), a garbage collection system and other parts. Its working principle is to use the sweeping brush to concentrate the ground garbage to the suction nozzle area, and then suck the garbage into the on-board garbage bin through the suction nozzle. Therefore, the street sweeper is efficient, environmentally friendly and easy to operate.

[0003] However, the suction nozzle height adjustment structure in conventional sweepers usually adopts manual operation or complex mechanical structure, and the adjustment process is time-consuming and labor-intensive. Especially when facing different terrains or garbage types, the negative pressure suction nozzle does not fit the ground well and is difficult to quickly adjust to the appropriate height, affecting the cleaning efficiency and quality.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 An embodiment of the utility model provides an electric lifting device for a suction nozzle of a sweeper, comprising: a movable plate 1.

[0020] Among them, such as Figures 1-4As shown, the top of the movable plate 1 is symmetrically hinged with two connecting rods 3, the ends of the connecting rods 3 are hinged with mounting brackets 2, the front surface of the mounting bracket 2 is installed with an electric push rod 4, the piston rod of the electric push rod 4 is installed with an articulated seat 14, the bottom of the articulated seat 14 is fixedly connected to the top of the movable plate 1, and a pipe joint 5 is embedded in the top of the movable plate 1. A threaded hole 11 is provided at one end of the connecting rod 3 close to the articulated seat 14, and an adjusting bolt 10 is threadedly connected to the internal thread of the threaded hole 11.

[0021] When in use, the electric push rod 4 drives the movable plate 1 to move up and down within a certain range, thereby driving the movable plate 1 to move up and down. The movable plate 1 is connected to the negative pressure suction nozzle through the pipe joint 5 embedded in the top. One end of the connecting rod 3 is hinged to the mounting bracket 2, and the other end is hinged to the movable plate 1. By adjusting the length of the adjusting bolt 10 in the threaded hole 11, the end of the adjusting bolt 10 abuts against the top of the movable plate 1, so that the inclination angle of the movable plate 1 changes.

[0022] Further, refer to Figure 1 and Figure 2 A first reinforcing rib 6 is welded on the top of the movable plate 1 , and a second reinforcing rib 13 is welded on the bottom of the movable plate 1 . The first reinforcing rib 6 and the second reinforcing rib 13 can increase the overall strength and anti-deformation performance of the movable plate 1 .
