Technical Field

[0001] This utility model relates to a road sweeper, specifically a zoned suction sweeper. Background Technology

[0002] Currently, the suction nozzles of zoned suction sweepers on the market are generally full-width suction structures, specifically, they perform simultaneous garbage suction operations along the width of the highway.

[0003] Chinese patent CN 106400723 B discloses a "sweeper suction cup device and sweeper", including a suction cup, rollers and a height adjustment mechanism; the height adjustment mechanism includes a connecting body, a moving part, a rotating part and a connecting bolt; the moving part is provided with a second engaging part that engages with a first engaging part, the first engaging part and the second engaging part engage to make the moving part move up and down relative to the connecting body, so as to realize the adjustable support height of the rollers on the suction cup; by changing the position of at least two nuts on the connecting bolts, the position of the supporting connecting plate is changed, so as to realize the adjustable height position of the connecting body relative to the suction cup, thereby realizing the continuous adjustment of the suction cup device's height above the ground. Chinese patent CN 116556247A discloses a "zonal suction and sweeping vehicle", which includes a dust collection device and a sweeping device installed under the chassis. The dust collection device includes several dust collection ports, a front rubber plate, a side rubber plate, and a roller brush installed on the suction cup body. The sweeping device includes two front sweeping discs and two rear sweeping discs. The outermost edges of the two rear sweeping discs respectively cover more than 1 / 3 of the area from the center to the outermost edge of the corresponding front sweeping disc in the left and right directions. The suction area of ​​the suction cup body covers more than 1 / 4 of the area from the center to the outermost edge of the rear sweeping disc in the left and right directions. The suction cup has a fast suction speed, the sweeping discs do not miss any areas when sweeping at high speed, the sweeping operation is highly efficient, and the cleaning effect is good.

[0004] However, in reality, garbage on highways is generally distributed longitudinally along the length of the highway, and the distribution width is less than 1 meter. The garbage is usually on the right side of the emergency lane or the left side of the overtaking lane. When the integrated suction cup is used for suction, some of it is in an empty suction state, and some suction power is not used, thus wasting suction energy. The aforementioned road sweepers cannot solve this problem. Utility Model Content

The central suction cup is mounted on the suction cup mounting frame, with its suction end facing the ground and its output end connected to the trash can via a central suction tube, for initial suction of trash within the width of the vehicle.

[0014] An automatic valve is also provided at the connection end between the central suction tube and the trash can to control the connection or disconnection between the central suction cup and the trash can;

[0015] The rollers are located on the side of the suction cup mounting frame away from the cleaning device, and the lifting end of the lifting device is connected to the suction cup mounting frame to control the lifting of the suction cup mounting frame.

[0016] Furthermore, the rectangular movable frame includes a rectangular mounting frame and roller assemblies disposed on the left and right sides of the rectangular mounting frame;

[0017] The air blowing channel is located between the upper and lower surfaces of the rectangular mounting frame. The upper surface of the rectangular mounting frame has multiple air blowing pipe installation ports. One end of the air blowing pipe is connected to the air blowing channel through the air blowing pipe installation port, and the other end is connected to the air outlet of the trash can. An air blowing strip is provided on the lower surface of the rectangular mounting frame near the rear of the vehicle, and multiple air blowing ports are provided on the air blowing strip. Multiple rear suction cups are evenly arranged below the rectangular mounting frame.

[0026] The beneficial effects of this utility model are:

[0027] [1] This utility model discloses a zoned suction sweeper that uses a central suction cup mechanism to initially pick up ground debris, and then uses a rear suction cup mechanism to pick up the ground debris a second time, which effectively improves the cleaning effect of the ground. By controlling the independent on / off of each rear suction cup through an automatic valve, the suction energy of the rear suction cup can be adjusted, allowing for targeted suction operations for different road conditions. It can realize multiple suction working modes such as left and right suction or strong and weak suction, effectively and rationally allocate and utilize suction energy, and apply suction force to different road conditions to further ensure the cleaning intensity of the road surface, effectively improving the cleaning efficiency and cleaning quality of the sweeper.

[0028] [2] This utility model controls the independent on / off state of each middle suction cup and rear suction cup through automatic valves, thereby enabling independent control of the connection or closure of each suction pipe and garbage bin. This allows the zoned suction sweeper to perform left-side, right-side, and full-width suction working modes, making it more adaptable to various cleaning and construction road conditions and effectively improving the practicality and applicability of the sweeper.

[0029] [3] This utility model has four rear suction cups evenly arranged along the width of the vehicle by the rear suction cup mechanism, which is divided into relatively independent sections in width. The rear suction cups in each section are connected to automatic valves through suction pipes. Depending on the state of garbage on the highway, the individual or combined opening of each automatic valve can be controlled to realize the suction function of different combinations of rear suction cups, so as to ensure the full utilization of suction energy.

[0030] [4] This utility model sets multiple air outlets at the rear end of the suction cup mechanism at the rear end, so that the ground garbage is suspended in the air under the action of the sweeping force, and then the garbage is picked up by the suction force of the rear suction cup. This can clean up the ground garbage more comprehensively and effectively improve the sweeping force and sweeping quality of the sweeper. Attached Figure Description
