Description

Technical Field

[0001] This utility model relates to the field of sanitation vehicle technology, and in particular to a sweeper truck. Background Technology

[0002] With the rapid advancement of urbanization, cities are continuously expanding and road networks are constantly extending, making the task of cleaning and maintaining urban roads increasingly arduous. The traditional manual cleaning method is not only extremely inefficient and inadequate for handling large-scale and long-distance road cleaning tasks, but also faces significant economic challenges due to the rising labor costs year by year.

[0003] Urban road structures are diverse. Taking urban expressways as an example, they typically consist of main roads and auxiliary roads. On main roads, vehicles travel at high speeds. To prevent traffic congestion or even accidents caused by road cleaning operations, there are high requirements for the operating speed of sanitation vehicles, which must be able to operate quickly and efficiently. However, the situation on ring road auxiliary roads is more complex. The types of traffic participants are diverse, and sanitation vehicles are mostly heavy-duty vehicles. Operating in such a complex road environment necessitates controlling operating speeds for safety reasons.

[0004] Existing sweeper trucks have revealed significant shortcomings in the face of such diverse urban road cleaning needs. In main road cleaning scenarios requiring rapid operation, their operating speed is difficult to increase, resulting in low cleaning efficiency and failing to meet the timeliness requirements of expressway traffic conditions. In complex road conditions such as ring road auxiliary roads, even if speed needs to be controlled for safety reasons, there is not enough room for optimization of their operating speed, making it difficult to improve operating efficiency while ensuring safety, which is detrimental to improving the overall quality of sweeper truck use.

The first sweeping disc 2021 and the second sweeping disc are respectively mounted on both sides of the vehicle chassis 1. Through the cooperation of the first sweeping disc 2021 and the second sweeping disc, it is convenient to clean the ground and collect garbage for the first suction nozzle 203 to collect into the garbage bin 5. The structure is simple and easy to design and implement.

[0049] Specifically, in this embodiment, both the first sweeping disc 2021 and the second sweeping disc adopt the sweeping disc structure in the prior art, and the rotation direction of the sweeping disc can also refer to the rotation direction of the sweeping disc in the prior art, which will not be elaborated further in this embodiment. The attached figure used in this embodiment is the figure of the left side of the vehicle, so the second sweeping disc is not shown in the figure. The structure of the second sweeping disc can refer to the structure of the first sweeping disc 2021.

[0050] To better connect the first suction nozzle 203 with the trash can 5, combined Figure 1 and Figure 2As shown, the first connecting unit 204 of the first cleaning mechanism 2 of the sweeper in this embodiment includes a first extension pipe 2041 disposed inside the garbage bin 5, and a first flexible connecting pipe 2042 connecting the first extension pipe 2041 and the first suction nozzle 203. A first valve 2043 is provided between the first extension pipe 2041 and the first flexible connecting pipe 2042, and the first extension pipe 2041 extends from the vehicle chassis 1 towards the rear of the vehicle. In this embodiment, the number of first extension pipes 2041 can be, for example, two, and the number of first flexible connecting pipes 2042 that cooperate with them can also be two. The setting of the first extension pipe 2041 facilitates raising the position of garbage entering the garbage bin 5 and avoids sewage backflow. The setting of the first flexible connecting pipe 2042 facilitates the connection between the first suction nozzle 203 and the first extension pipe 2041. The setting of the first valve 2043 facilitates the control of the opening and closing of the first connecting unit 204. The structure is simple and easy to design and implement.

[0051] In order to better perform high-pressure water spray cleaning on the ground, combined with Figure 1 and Figure 2 As shown, the first spray assembly 201 of the sweeper truck in this embodiment includes a first main spray bar 2011, a first left-side spray bar 2012, and a first right-side spray bar mounted on the first suction nozzle 203.

By setting the first main spray bar 2011 behind the first suction nozzle 203, it is convenient to perform high-pressure water spray cleaning on the ground after it has been sucked up by the first suction nozzle 203. By setting the first left-side spray bar 2012 and the first right-side spray bar above the left and right sides of the first suction nozzle 203, while performing high-pressure water spray on the ground, it can also assist the first suction nozzle 203 in gathering and collecting garbage, which is beneficial for design and implementation. The accompanying drawing used in this embodiment is the drawing of the left side of the vehicle, so the first right spray bar is not shown in the drawing. The structure of the first right spray bar can be referred to the structure of the first left spray bar 2012.

[0052] In order to better arrange the second cleaning mechanism 3, combined with Figures 1 to 3As shown, the second cleaning mechanism 3 of the sweeper in this embodiment includes a bracket, a second cleaning unit 302, a second suction nozzle 303, and a second connecting unit 304.

Viewed from the front of the vehicle, the second suction nozzle 303 and the second cleaning unit 302 are sequentially arranged on the bracket. The second suction nozzle 303 is connected to the garbage bin 5 through the second connecting unit 304. The bracket facilitates the arrangement of the second cleaning unit 302, the second suction nozzle 303, and the second connecting unit 304. The second cleaning unit 302 can further clean up the garbage on the ground and collect it into the garbage bin 5 through the second suction nozzle 303. The second connecting unit 304 facilitates the connection between the second suction nozzle 303 and the garbage bin 5. The structure is simple and easy to design and implement.

[0053] To better assist the operation of the second cleaning mechanism 3, combined with Figures 1 to 3 As shown, the second spray assembly 202 of the second cleaning mechanism 3 of the sweeper truck in this embodiment includes a second main spray bar 3011, a second left spray bar 3012, and a second right spray bar 3013 mounted on the second suction nozzle 303. Viewed from the front of the vehicle, the second main spray bar 3011 is located behind the second cleaning unit 302, the second left spray bar 3012 is located above the left side of the second suction nozzle 303, and the second right spray bar 3013 is located above the right side of the second suction nozzle 303. By setting the second main spray bar 3011 behind the second cleaning unit 302, it is convenient to spray high-pressure water onto the ground after the second cleaning unit 302 has cleaned it. By setting the second left spray bar 3012 and the second right spray bar 3013 above the left and right sides of the second suction nozzle 303, it is convenient to assist the second suction nozzle 303 in collecting garbage while spraying high-pressure water onto the ground. The structure is simple and easy to design and implement.

[0054] It is worth mentioning that in this embodiment, the first left spray bar 2012, the first right spray bar, the second left spray bar 3012, and the second right spray bar 3013 can all be mounted on their respective installation positions by pneumatic rod rotation, and the extension and retraction of the cylinder can be used to control the unfolding angle of the spray bar.

[0055] In order to better clean up debris on the ground, combined with Figures 1 to 3 As shown, the second cleaning unit 302 of the second cleaning mechanism 3 of the sweeper in this embodiment includes a roller brush 3021 mounted on a bracket and located between the second main spray bar 3011 and the second suction nozzle 303. The roller brush 3021 facilitates the cleaning of the garbage left by the first cleaning unit 202, further enhances the cleaning power, and is conducive to design and implementation.

[0056] Specifically, in combination Figure 2As shown, the second connecting unit 304 of the second cleaning mechanism 3 of the sweeper in this embodiment includes a second extension pipe 3041 disposed inside the garbage bin 5, a second flexible connecting pipe 3042 disposed between the second extension pipe 3041 and the second suction nozzle 303, a second valve 3043 disposed between the second extension pipe 3041 and the second flexible connecting pipe 3042, and an end cap hinged to the end of the second extension pipe 3041 facing into the garbage bin 5. The second extension pipe 3041 facilitates raising the position of garbage entering the garbage bin 5, preventing sewage backflow. The second flexible connecting pipe 3042 facilitates the connection between the second extension pipe 3041 and the second suction nozzle 303. The second valve 3043 facilitates the control of the opening and closing of the second connecting unit 304. The end cap prevents garbage from the garbage bin 5 from entering the second connecting unit 304 when the second cleaning mechanism 3 is not in use. The structure is simple and easy to design and implement.

[0057] It is worth mentioning that the first cleaning mechanism 2 in this embodiment can be used independently. When the second cleaning mechanism 3 is not working, the end cap on the top of the second extension tube 3041 can prevent debris from entering the second extension tube 3041 and affecting the use of the second cleaning mechanism 3. When the second valve 3043 of the second cleaning mechanism 3 is closed, the top of the second extension tube 3041 is also closed due to the end cap.

[0058] To better protect the structure of the garbage bin 5, the top of the garbage bin 5 of the sweeper in this embodiment is provided with a protective structure, which covers the connection between the first suction nozzle 203 and the second suction nozzle 303 and the garbage bin 5. By providing this protective structure, covering the top of the garbage bin 5, it helps to prevent garbage sucked into the garbage bin 5 from directly impacting the top of the garbage bin 5, thus protecting the garbage bin 5 and facilitating its design and implementation.

[0059] Specifically, the protective structure includes a rectangular reinforcing plate on the top of the garbage bin 5, and four trapezoidal reinforcing side plates connected to the four sides of the rectangular reinforcing plate and inclined downward from the top of the garbage bin 5. When garbage enters the garbage bin 5 through the first extension pipe 2041 or the second extension pipe 3041, it will impact the reinforcing plate and the reinforcing side plates to prevent the garbage from directly impacting the top of the garbage bin 5.

[0060] The sweeper truck of this embodiment can quickly clean up garbage on the ground and sweep the ground. Through the cooperation of the first sweeping mechanism 2, the second sweeping mechanism 3, the high-pressure water system 4, the garbage bin 5 and the blower assembly 6 set on the vehicle chassis 1, it can quickly sweep up garbage on the ground, which helps to improve the working efficiency of the sweeper truck and thus improve the quality of use of the sweeper truck.
