Description

Technical Field

[0001] This utility model belongs to the technical field of road maintenance equipment, specifically relating to a median strip garbage sweeping robotic arm and a highway median strip garbage rapid suction and sweeping vehicle. Background Technology

[0002] With the rapid development of highways, the cleaning and maintenance of median strips has become increasingly important. Median strips are usually planted with greenery or equipped with anti-glare facilities, which easily lead to the accumulation of fallen leaves, plastic waste, gravel, and other debris. If not cleaned in time, this not only affects the appearance of the road but may also affect driving safety due to the scattering of garbage.

[0003] Currently, garbage removal in highway medians mainly relies on manual sweeping or the use of municipal cleaning equipment, which presents the following problems: manual sweeping is inefficient and risky; maintenance workers need to enter the highway median to work, facing safety hazards from high-speed traffic, and the cleaning speed is slow; traditional municipal road sweeping vehicles often require lane closures or multiple crash barriers, which obstructs traffic and increases costs, making it difficult to meet the needs of long-distance continuous operations; existing sweeping equipment has poor adaptability, and the brush devices of traditional sweepers are mostly fixed or have simple adjustable structures, often installed on the side and under the vehicle, resulting in insufficient sweeping distance and difficulty in cleaning the inside of the median.

[0004] To address the aforementioned issues, there is an urgent need for a dedicated garbage sweeping device for highway medians that can improve sweeping efficiency while ensuring operational safety and adapting to the median environment. Utility Model Content

[0005] The purpose of this utility model is to provide a median strip garbage sweeping robotic arm and a highway median strip garbage rapid suction sweeper to solve the technical problems of high risk of manual maintenance, slow sweeping speed, traffic obstruction by traditional municipal sweepers, poor adaptability, and insufficient sweeping distance in the prior art, so as to meet the requirements of rapid and efficient garbage sweeping under the influence of highway median strip guardrails.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The first objective of this utility model is to provide a centrally located garbage sweeping robotic arm, comprising a first arm, a second arm, and a third arm; the first end of the first arm is hinged to a first arm rotary cylinder, the end of the first arm is hinged to the first end of the second arm via a second arm rotary cylinder, and the end of the second arm is hinged to the first end of the third arm via a third arm adjusting cylinder.

[0008] One section of the boom is equipped with a lifting cylinder, the fixed end of which is hinged to a rotary cylinder, and the telescopic end of which is hinged to the middle of the lower side of the boom. The end of the three-section boom is connected to a flexible long-bristle disc brush via a disc brush base. The rotary cylinder of the two-section boom is connected to a garbage baffle, which is arranged around the flexible long-bristle disc brush.

[0009] Furthermore, the disc brush base includes a first section plate and a second section plate that are hinged to each other. The first section plate is hinged to the telescopic end of the disc brush lateral tilt angle adjustment cylinder, and the fixed end of the disc brush lateral tilt angle adjustment cylinder is connected to the end of the three-section arm to adjust the lateral tilt angle of the flexible long bristle disc brush. A disc brush longitudinal tilt angle adjustment cylinder is hinged between the first section plate and the second section plate to adjust the longitudinal tilt angle of the flexible long bristle disc brush. The first section plate and the second section plate form a parallel constrained rotational pair.

[0010] Furthermore, the first arm has an upper arm and a lower arm arranged in parallel. The beginning ends of the upper arm and the lower arm are respectively hinged to the base of the first arm rotary cylinder, and the ends of the upper arm and the lower arm are respectively hinged to the base of the second arm rotary cylinder, so that the second arm remains parallel to the ground during the process of the first arm rising and falling in the vertical plane.

[0011] Furthermore, the garbage baffle is hinged to the base of the two-section boom rotary cylinder via ear plates. The two ends of the baffle adjustment cylinder are respectively hinged to the front end of the garbage baffle and the middle section of the two-section boom via fixed ear plates. The extension and retraction of the cylinder causes the garbage baffle to rotate in the horizontal plane.

[0012] Furthermore, the two-section boom has a double-arm structure, with the first ends of the double arms respectively hinged to the base of the two-section boom rotary cylinder, and the ends of the double arms are hinged together to the base of the three-section boom rotary cylinder at the intersection of the double arms, forming a triangular structure.

[0013] Furthermore, the bristles of the flexible long-bristle disc brush are made of nylon material with a low Young's modulus to enable the cleaning of debris inside the center strip.

[0014] The second objective of this utility model is to provide a high-speed median strip garbage sweeping vehicle. Based on the aforementioned median strip garbage sweeping robotic arm, the base of a section of the arm rotary cylinder is connected to a slider, the slider is mounted on a slide rail, the fixed end of the slider pushing cylinder is connected to one end of the slide rail, the telescopic end of the slider pushing cylinder is connected to the slider, the slide rail is mounted on a sweeping device mounting frame, and the sweeping device mounting frame is bolted to the vehicle chassis frame.

[0015] Furthermore, the highway median strip garbage sweeper also has a garbage collection suction port, which is fixed to the vehicle chassis frame by bolts.

[0016] Furthermore, the waste collection suction port includes a front suction port, which is connected to the vehicle chassis frame via a front suction port adjusting cylinder mounting bracket; the two ends of the front suction port adjusting cylinder are respectively hinged to the front suction port adjusting cylinder mounting bracket and one side of the front suction port, and there are two front suction port adjusting cylinders, which are used to adjust the ground height of the front suction port.

[0017] Furthermore, the waste collection suction port includes a side suction port, which is fixed to the longitudinal frame of the vehicle body by a side suction port mounting bracket. The end of the side suction port mounting bracket is hinged to the base of the connecting rod and the side suction port height adjustment cylinder via a side suction port rotation cylinder to control the extension and retraction of the side suction port. The two ends of the side suction port height adjustment cylinder are connected to the middle of the connecting rod and its base, and the end of the connecting rod is hinged to the side suction port to adjust the height of the side suction port off the ground. The side suction port is installed in the middle of the vehicle, and the rotation cylinder adjusts the side suction port to maintain an angle of 30° to 45° with the front of the vehicle.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The median strip garbage sweeping robotic arm provided by this utility model is simple to install and use. Through the coordination of multiple robotic arms, connecting cylinders, lifting cylinders, disc brushes, and garbage baffles, the overall device can be easily extended or retracted. One arm section achieves 180° rotation in the horizontal plane via a rotary cylinder, satisfying garbage sweeping needs at both ends of the road. The lifting cylinder of the first arm section allows adjustment of the disc brush's height off the ground. The rotary motion of the second and third arm sections increases the working distance of the overall device. During sweeping operations, the garbage baffle is adjusted to a suitable position via a baffle adjustment cylinder to block garbage, effectively preventing garbage from being thrown too far.

[0020] Furthermore, the segmented disc brush base enables relative rotation of the first and second sections of the disc brush. The front-to-back (longitudinal) and left-to-right (lateral) tilt angles of the disc brush are controlled by connecting two disc brush tilt angle adjustment cylinder boxes respectively. The flexible long bristle disc brush can penetrate deep into the middle partition, ultimately satisfying the cleaning work of the garbage inside the middle partition.

[0021] Furthermore, the upper and lower arms of the first boom adopt a parallelogram structure to keep the second boom and subsequent working devices parallel to the ground.

[0022] The highway median strip garbage rapid suction sweeper provided by this utility model has a slider that allows for left and right sliding adjustment of the lateral position of the entire median strip garbage sweeping robotic arm, effectively adjusting the relative position of the disc brush and the median strip, and expanding the sweeping range.

[0023] Furthermore, the front and side suction ports can be bolted to the vehicle's crossbeams and side beams to work in conjunction with the two working modes of the disc brush, ensuring that the swept garbage is thoroughly cleaned and not scattered on the road surface, thus preventing traffic hazards.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0033] The following is combined with Figure 1 , Figure 2 , Figure 3 The technical solution of this utility model is described in detail below:

[0034] This utility model provides a highway median strip garbage rapid suction and sweeping vehicle, including a vehicle body and a median strip garbage sweeping robotic arm, which is mounted on the vehicle chassis.

[0035] See Figure 1 and Figure 2 The central partition garbage sweeping robotic arm includes a first arm 4, a first arm rotation cylinder 5, a first arm lifting cylinder 6, a second arm 7, a second arm rotation cylinder 8, a third arm 9, a third arm adjustment cylinder 10, a disc brush base 11, a disc brush lateral tilt angle adjustment cylinder 12, a disc brush longitudinal tilt angle adjustment cylinder 13, a flexible long bristle disc brush 14, a garbage baffle 15, a baffle adjustment cylinder 16, and a sweeping device mounting frame 17.

[0036] Specifically, such as Figure 1 As shown, the base of the first-section arm rotary cylinder 5 is fixedly connected to the slider 2. The first-section arm 4 rotates around the first-section arm rotary cylinder 5 in the horizontal plane to further adjust the distance between the cleaning device and the median strip.

[0037] Specifically, the two ends of the lifting cylinder 6 of the first arm are respectively hinged to the rotating cylinder 5 of the first arm and the middle of the first arm 4 through fixed ear plates, so as to realize the lifting and lowering of the first arm in the vertical plane and adjust the height of the brush off the ground.

[0038] Specifically, the first arm 4 has a double-arm parallelogram structure, and its end is hinged to the base of the second arm rotary cylinder 8, so that the second arm 7 remains parallel to the ground during its vertical lifting and lowering process. The second arm 7 rotates around the second arm rotary cylinder 8 in the horizontal plane, which can further increase the working distance. The second arm 7 adopts a double-arm triangular structure to improve structural stability.

[0039] Specifically, such as Figure 2 As shown, the three-section arm 9 is hinged to the end of the two-section arm 7. The two ends of the three-section arm adjusting cylinder 10 are respectively hinged to the base of the two-section arm rotating cylinder 8 and the three-section arm 9 through fixed ear plates. The extension and retraction of the three-section arm adjusting cylinder 10 causes the three-section arm 9 to rotate around the end of the two-section arm 7 in the horizontal plane.

[0040] Specifically, the disc brush base 11 has a segmented structure, and the connection between the two base plates is a parallel constrained rotating pair. The two ends of the disc brush lateral tilt angle adjustment cylinder 12 are respectively hinged to the end of the three-section arm 9 and the fixing ear plate of the first section plate of the disc brush base 11. The disc brush longitudinal tilt angle adjustment cylinder 13 is respectively hinged to the two base plates of the disc brush base 11. The cylinders extend and retract to adjust the front, back, left and right tilt angles of the disc brush.

[0041] Specifically, the garbage baffle 15 is hinged to the base of the two-section arm rotary cylinder 8 via ear plates. The two ends of the baffle adjusting cylinder 16 are respectively hinged to the front end of the garbage baffle 15 and the middle section of the two-section arm 7 via fixed ear plates. The cylinder extends and retracts to make the garbage baffle 15 rotate in the horizontal plane.

[0042] The base of the rotating cylinder 5 of the first arm of the median strip garbage sweeping robot arm is fixedly connected to the slider 2. The slider pushing cylinder 3 pushes the slider 2 to move left and right along the slide rail 1. The first arm 4 rotates around the rotating cylinder 5 in the horizontal plane to further adjust the distance between the sweeping device and the median strip.

[0043] The entire central separation zone garbage sweeping robotic arm is bolted to the vehicle chassis frame via the sweeping device mounting bracket 17.

[0044] like Figure 2 As shown, the utility model of this waste collection device consists of a front suction port mounting bracket 18, a front suction port adjusting cylinder 19, a front suction port adjusting cylinder mounting bracket 20, a front suction port 21, a side suction port 22, a side suction port mounting bracket 23, a side suction port height adjusting cylinder 24, a side suction port rotation cylinder 25, a centrifugal fan 26, and a settling box 27.

[0045] The front suction port mounting bracket 18 is bolted to the vehicle chassis frame, and one end of it is hinged to the middle of the front suction port 21 via a connecting rod. The front suction port adjusting cylinder mounting bracket 20 is bolted to the vehicle chassis frame, and the two front suction port adjusting cylinders 19 are hinged at both ends to the front suction port adjusting cylinder mounting bracket 20 and the two sides of the front suction port 21, respectively, so as to adjust the height of the front suction port from the ground.

[0046] Specifically, such as Figure 5 As shown, the side suction port 22 is fixed to the longitudinal frame of the vehicle body with bolts through the side suction port mounting bracket 23. The end of the side suction port mounting bracket 23 is hinged to the connecting rod and the base of the side suction port height 24 through the side suction port rotation cylinder 25, which can control the extension and retraction of the side suction port 22. The two ends of the side suction port height adjustment cylinder 24 are connected to the middle of the connecting rod and its base. The end of the connecting rod is hinged to the side suction port 22, which can adjust the height of the side suction port 22 from the ground.

[0047] The two suction ports can be bolted to the vehicle's crossbeam and side beam to cooperate with the two working modes of the disc brush: clockwise rotation and counterclockwise operation. When working clockwise, the front suction port mainly works; when working counterclockwise, the side suction port is installed in the middle of the vehicle and can be adjusted by a hydraulic cylinder to maintain an angle of 30° to 45° with the front of the vehicle.

[0048] The centrally located garbage sweeping robotic arm is connected to the vacuum sweeper via a slider and rail mechanism. During operation, the slider 2 is pushed by the slider push cylinder 3, which drives the slider 2 to move horizontally left and right along the rail 1. The arm rotation cylinder 5 can drive the arm 4 to rotate 180° in the horizontal plane. The arm lifting cylinder 6 can adjust the height of the arm 4, thereby determining the final working height of the flexible long bristle disc brush 14.

[0049] The second-section arm 7 is hinged to the end of the first-section arm 4 via the second-section arm rotation cylinder 8, enabling it to rotate in the horizontal plane around the end of the first-section arm 4, further increasing the working distance of the central separation zone garbage sweeping robot arm. The third-section arm 9 is hinged to the end of the second-section arm 7, and rotates in the horizontal plane around the end of the second-section arm 7 with the push-pull movement of the third-section arm adjustment cylinder 10. The end of the third-section arm 9 is hinged to the disc brush base 11, and the disc brush lateral tilt angle adjustment cylinder 12 mounted on the third-section arm 9 adjusts the left and right tilt angles of the flexible long bristle disc brush 14 through its telescopic movement. The front and rear tilt angles of the flexible long bristle disc brush 14 are adjusted by the disc brush longitudinal tilt angle adjustment cylinder 13 and the segmented disc brush base 11. In addition, the front end of the second-section arm 7 is hinged to the garbage baffle 15 via the baffle adjustment cylinder 16, allowing the baffle 15 to rotate around the base of the second-section arm 7, preventing some garbage from being thrown too far during operation and thus failing to be effectively swept. The front suction port 21 and the side suction port 22 are connected to the frame and are height adjustable. They are connected to the inlet of the centrifugal fan 26 and enter the settling box 27 through a hose, such as a hose with a diameter of 170mm, thereby realizing the dust collection work.

[0050] The working process of the highway median strip garbage rapid suction and sweeping vehicle provided by this utility model is as follows:

[0051] like Figure 1As shown, taking the current view direction as an example, when work begins, the slider advance cylinder 3 pushes the cleaning device to the rightmost position. The first-section arm rotation cylinder 5 and the first-section arm lifting cylinder 6 push the first section arm to a state parallel to the ground and perpendicular to the slide rail 1. The second-section arm rotation cylinder 8 pushes the subsequent working device to a position parallel to the slide rail 1. Finally, the third-section arm adjusting cylinder 10 adjusts the precise position of the disc brush, and the disc brush lateral adjusting cylinder 12 and the disc brush longitudinal tilt adjusting cylinder 13 ultimately adjust the disc brush tilt angle, allowing the disc brush to penetrate deep into the median strip. Figure 2 As shown, the extension and retraction of the suction port adjusting cylinder 13 can adjust the height of the suction port 21 from the ground.

[0052] like Figure 3 , 4 As shown, the entire working device is retracted through the coordination of the various hydraulic cylinders. The plane of the first arm 4 is ultimately parallel to the slide rail 1 and raised to a certain height, while the plane of the second arm 7 is parallel to the first arm 4. This ultimately achieves the goal of saving space in the retracted state. Figure 5 , 6 As shown, two hydraulic cylinders control the rotation and height of the side suction port, which can extend out of the vehicle at a 45° side angle during operation. The suction port is connected to the blower via a hose to pick up garbage.

[0053] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of the claims of this utility model.
