Abstract
Description
Technical Field
[0001] This utility model relates to road sweepers, specifically to a rear suction cup structure for a road sweeper with zoned suction. Background Technology
[0002] Existing sweeper trucks all use a full-width suction structure, which means that garbage is simultaneously sucked up across the width of the suction cup. However, garbage on actual highways is generally distributed longitudinally and is less than 1 meter wide. The garbage is usually on the right side of the emergency lane or the left side of the overtaking lane. When the full-width suction structure is used, part of the width is in an empty suction state, and part of the suction power is not utilized, thus wasting suction energy and resulting in low suction efficiency. Furthermore, its suction method is relatively simple and cannot be applied to various road cleaning and construction conditions. Utility Model Content
[0003] The purpose of this invention is to solve the technical problems of existing road sweepers having a single suction method, which cannot be applied to various road cleaning conditions, and cannot make full use of suction energy, resulting in low suction efficiency. Therefore, this invention proposes a road sweeper rear suction cup structure with zoned suction.
[0004] To achieve the above objectives, the technical solution proposed by this utility model is as follows:
[0005] A rear suction cup structure for a road sweeper with zoned suction, comprising a rear suction cup assembly installed at the rear of the road sweeper chassis, is characterized by:
[0006] The rear suction cup assembly includes a rectangular movable frame adapted to the width of the vehicle, and the rectangular movable frame includes a rectangular mounting frame and roller assemblies disposed at the left and right ends of the rectangular mounting frame;
[0007] A blowing channel is provided between the upper and lower surfaces of the rectangular mounting frame. At least one blowing pipe installation port is opened on the upper surface of the rectangular mounting frame, and a blowing pipe is installed on the blowing pipe installation port. The blowing channel is connected to the air outlet of the garbage bin of the sweeper through the blowing pipe. A blowing strip is provided on the lower surface of the rectangular mounting frame near the rear of the sweeper. Multiple blowing ports are opened on the blowing strip. The gas discharged from the air outlet of the garbage bin blows the garbage on the ground through the blowing pipe, the blowing channel and the blowing ports in sequence.
[0008] Multiple rear suction cups are evenly arranged below the rectangular mounting frame. The suction end of each rear suction cup is opposite to the ground, and the output end is connected to the trash can through a rear suction pipe for suctioning up the trash blown by the air nozzle. An automatic valve is provided on the connection end of the rear suction pipe to the trash can to control the connection or disconnection between the rear suction cup and the trash can. By adjusting the automatic valve between each rear suction pipe and the trash can, each rear suction cup can be controlled to work individually or in combination, thereby realizing different suction states of the rear suction cup assembly.
[0009] Furthermore, each of the rear suction cups includes a circular suction cup and a V-shaped suction cup. Each of the V-shaped suction cups is tangentially connected to the outer ring of the circular suction cup near the air outlet, and is used to pick up ground debris blown up by the air outlet.
[0010] Furthermore, each of the V-shaped suction cups is connected by an arc-shaped tube for comprehensive suction of ground debris within the vehicle width.
[0011] Furthermore, four rear suction cups are evenly arranged along the width of the vehicle on the rectangular mounting frame, and the four rear suction cups are connected to the garbage bin through corresponding rear suction pipes and automatic valves.
[0012] Furthermore, the upper surface of the rectangular mounting frame is provided with two air pipe mounting ports, which are located at 1 / 4 and 3 / 4 of the upper surface of the rectangular mounting frame, respectively.
[0013] Furthermore, each of the aforementioned air ducts is equipped with an automatic valve at the connection end with the air outlet of the garbage bin, which is used to control the connection or disconnection between the air duct and the air outlet of the garbage bin, thereby controlling the air volume of the air duct.
[0014] Furthermore, buffer chains connected to the chassis of the sweeper are provided at the four corners of the rectangular mounting frame to ensure the stability of the rectangular mobile frame.
[0015] Furthermore, each of the air outlets is equipped with an air guide plate to guide the gas forward.
[0016] Furthermore, the air outlet is an angled air outlet, used to blow the ground debris forward and sweep it below the rear suction cup.
[0017] The beneficial effects of this utility model are:
[0018] [1] The rear suction cup structure of the sweeper with partitioned suction is simple and has strong stability. The automatic valve controls the independent on / off of each rear suction cup, effectively distributing and utilizing the suction energy. Different suction forces are applied to different road conditions, realizing multiple suction working modes, further ensuring the cleaning force of the road surface, and effectively improving the cleaning efficiency and cleaning quality of the sweeper.
[0019] [2] This utility model sets multiple air outlets on the lower surface of the rectangular mounting frame, 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 of the rear suction cup. This can clean the ground garbage more comprehensively and effectively improve the sweeping force and sweeping quality of the sweeper.
[0020] [3] The present invention forms a rear suction cup by combining a circular suction cup and a V-shaped suction cup. The V-shaped suction cup can completely cover the suction space within the width of the vehicle, while the circular suction cup can more concentratedly suction the garbage, effectively improving the suction efficiency of the device.
[0021] [4] By setting a guide plate at the air outlet, this utility model can concentrate the wind force and direction, guide the ground garbage to concentrate under the suction cup, and effectively enhance the cleaning and suction effect. Attached Figure Description

Detailed Implementation
[0026] like Figure 1 and Figure 2 As shown, a sweeper truck with a zoned suction system has a rear suction cup structure, which includes a rear suction cup assembly installed at the rear of the sweeper truck chassis. The rear suction cup assembly includes a rectangular moving frame 1 adapted to the width of the vehicle. The rectangular moving frame 1 includes a rectangular mounting frame 2 and roller assemblies 3 set at the left and right ends of the rectangular mounting frame 2. Buffer chains 14 connected to the chassis are provided at the four corners of the rectangular mounting frame 2 to ensure the stability of the rectangular moving frame 1.
[0027] A blowing channel is provided between the upper and lower surfaces of the rectangular mounting frame 2. Two blowing pipe installation ports 4 are opened on the upper surface of the rectangular mounting frame 2, located at 1 / 4 and 3 / 4 of the upper surface of the rectangular mounting frame 2, respectively. Blowing pipes 5 are installed on the blowing pipe installation ports 4. The blowing channel is connected to the air outlet of the garbage bin of the sweeper through the blowing pipes 5. A blowing strip 6 is provided on the lower surface of the rectangular mounting frame 2 near the rear of the sweeper. Multiple blowing ports 7 are opened on the blowing strip 6. The gas discharged from the air outlet of the garbage bin blows the garbage on the ground through the blowing pipes 5, the blowing channel and the blowing ports 7 in sequence. Each blowing port 7 is provided with a guide plate 15 to guide the gas forward. An automatic valve 10 is also provided at the connection end of each blowing pipe 5 and the air outlet of the garbage bin to control the connection or disconnection between the blowing pipe 5 and the air outlet of the garbage bin, thereby controlling the blowing air volume of the blowing channel.
[0028] The structure of the air outlet 7 can also adopt a slanted air outlet with an inclined angle, which can better guide the air direction to blow the ground garbage forward and blow it to the area below the rear suction cup, making it easier for the rear suction cup to pick it up.
[0029] Four rear suction cups 8 are evenly arranged along the width of the vehicle below the rectangular mounting frame 2. The suction end of each rear suction cup 8 is opposite to the ground, and the output end is connected to the trash can through the rear suction pipe 9, which is used to suck up the trash blown by the air nozzle 7. An automatic valve 10 is provided on the connection end of the rear suction pipe 9 and the trash can to control the connection or disconnection between the rear suction cup 8 and the trash can. By adjusting the automatic valve 10 between each rear suction pipe 9 and the trash can, each rear suction cup 8 can be controlled to work individually or in combination, thereby realizing different suction states of the rear suction cup assembly.
[0030] Each rear suction cup 8 includes a circular suction cup 11 and a V-shaped suction cup 12. Each V-shaped suction cup 12 is tangentially connected to the outer ring of the circular suction cup 11 near the air outlet 7, and is used to pick up the ground garbage blown up by the air outlet 7. Each V-shaped suction cup 12 is connected to each other by an arc-shaped tube 13, and is used to pick up all the ground garbage within the width of the vehicle.
