Description

Technical Field

[0001] This invention relates to the field of road cleaning technology, and in particular to a road cleaning device and method. Background Technology

[0002] Urban roads are an important part of urban infrastructure. With social development, people have higher and higher requirements for the road environment. Urban roads are not only related to the clean and tidy living environment of citizens, but also affect the appearance of a city.

[0003] On urban roads, especially highways, there is a high volume and variety of traffic. Most of these vehicles are freight trucks carrying miscellaneous items, which inevitably lead to spillage during operation. When the spilled material is large, such as glass, metal parts, tires, soil, or gravel, traditional cleaning trucks cannot effectively clean it up. In such cases, a garbage collector is necessary. However, the shovel plate structure of a garbage collector requires frequent replacement due to friction with the ground during operation. Traditionally, the shovel plate is installed by bolts onto the bucket. Users need to tighten these bolts very tightly during installation to ensure structural stability. However, over time, the bolt threads wear and loosen, causing the shovel plate to become loose. This not only affects the garbage collection process but also makes subsequent disassembly and replacement difficult. Summary of the Invention

[0004] One of the objectives of this invention is, at least, to provide a road cleaning device and method that addresses the problems existing in the prior art, by detachably fixing the shovel plate to the bucket using a snap-fit ​​method, thereby improving the performance of the shovel plate and facilitating its replacement.

[0005] To achieve the above objectives, the technical solution adopted by the present invention includes the following aspects.

[0006] A road cleaning device includes: a cylindrical bucket, a shovel, tires, a base frame, and a battery box; the cylindrical bucket has a hollow structure, including a first bottom surface and a second bottom surface, which are arranged opposite to each other, with a side surface between the first bottom surface and the second bottom surface; an opening is provided on the side surface of the cylindrical bucket, and a buckle is provided at the bottom of the opening, and the shovel is connected to the cylindrical bucket by the buckle;

[0007] The cylindrical bucket is horizontally fixed to the first end of the foundation frame, the battery box is vertically placed at the second end of the foundation frame, the tires are symmetrically arranged on both sides of the first end of the foundation frame, and the tires are rotatably connected to the bottom surface of the cylindrical bucket by a connecting rod; the first end of the connecting rod is connected to the first end of the foundation frame, and the second end of the connecting rod is connected to the outer wall of the bottom surface of the cylindrical bucket.

[0008] Preferably, the bottom of the opening is provided with two buckles, which are arranged opposite to each other and are set on the inner wall of the cylindrical hopper; the buckles are L-shaped structures, including a vertical side and a horizontal side integrally set on the top of the vertical side, the bottom of the vertical side is integrally connected to the inner wall of the cylindrical hopper, the first end of the horizontal side is integrally connected to the top of the vertical side, and the second ends of the horizontal sides of the two buckles both face the inner wall of the first bottom surface of the cylindrical hopper; the shovel plate is provided with a vertical limiting groove penetrating the shovel plate at the corresponding position of the buckle.

[0009] Preferably, the bottom of the cylindrical bucket opening is provided with an installation port, which penetrates the first bottom surface of the cylindrical bucket; a limiting rotating plate is rotatably provided on the outer side of the first bottom surface of the cylindrical bucket, and the limiting rotating plate is located outside the installation port.

[0010] Preferably, a stop block is horizontally provided at the bottom of the limiting rotating plate, and the stop block is horizontally fixed to the bottom of the cylindrical bucket installation opening.

[0011] Preferably, the inner wall of the second bottom surface of the cylindrical bucket is provided with a horizontal mounting groove that matches the end of the shovel plate, and the mounting groove is located at the bottom of the second bottom surface.

[0012] Preferably, a hydraulic rod is provided on the connecting rod body, one end of the hydraulic rod is connected to the connecting rod, and the other end is connected to the outer wall of the bottom surface of the cylindrical bucket.

[0013] Preferably, the top of both bottom surfaces of the cylindrical bucket is provided with an external interface for moving the cylindrical bucket.

[0014] Preferably, a push rod is horizontally arranged between the battery storage box and the cylindrical bucket. The first end of the push rod is located on the top of the battery storage box and is rotatably connected to the battery storage box, and the second end of the push rod is rotatably connected to the side of the cylindrical bucket.

[0015] Preferably, the mounting plate structure on the side of the battery box has multiple horizontally opened mounting holes, which are evenly distributed in a rectangular shape on the mounting plate.

[0016] The present invention also provides a road cleaning method using the aforementioned road cleaning device, comprising the following steps:

[0017] Step 1: Rotate the limiting rotating plate at the mounting opening on the first bottom surface of the cylindrical bucket to expose the mounting opening on the first bottom surface of the cylindrical bucket;

[0018] Step 2: Place the shovel plate horizontally into the cylindrical bucket from the installation opening on the first bottom surface of the cylindrical bucket and press it down so that the buckle is vertically inserted into the limiting groove of the shovel plate; push the shovel plate horizontally so that the L-shaped buckle moves horizontally along the limiting groove so that the horizontal edge above the L-shaped buckle is locked onto the top of the shovel plate.

[0023] In summary, by adopting the above technical solution, the present invention has at least the following beneficial effects:

[0024] By vertically setting a buckle at the bottom of the cylindrical bucket opening and setting a limiting groove that matches the buckle at the corresponding position on the shovel plate, the limiting groove penetrates the shovel plate, and the shovel plate is fixed to the cylindrical bucket by the buckle, which can improve the efficiency of shovel plate installation and disassembly; the shovel plate will not loosen during long-term use, which is conducive to improving the road cleaning effect.

[0025] By installing a hydraulic rod on the connecting rod, with one end connected to the connecting rod and the other end connected to the outer wall of the bottom surface (first bottom surface and second bottom surface) of the cylindrical hopper, the load-bearing capacity of the cylindrical hopper can be improved. When there is too much garbage inside the cylindrical hopper and the weight increases, the hydraulic rod will contract under pressure, thereby playing a buffering role. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so that the objectives, technical solutions, and advantages of the present invention will be clearer. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0032] Figure 1 The present invention illustrates a road cleaning device according to an exemplary embodiment of the present invention. The road cleaning device includes a cylindrical bucket 1, a shovel 2, tires 3, a base frame 4, and a battery box 5. The cylindrical bucket 1 is a hollow structure, including a first bottom surface and a second bottom surface, which are arranged opposite to each other, with a side surface between the first bottom surface and the second bottom surface. The cylindrical bucket 1 is horizontally fixed to the first end of the base frame 4. An opening is provided on the side surface of the cylindrical bucket 1. When it is fixed to the base frame 4, the opening is away from the base frame and located at the bottom of the cylindrical bucket 1. The shovel 2 is vertically placed at the bottom of the opening on the side surface of the cylindrical bucket 1. The tires 3 are symmetrically arranged on both sides of the first end of the base frame 4, and a connecting rod is rotatably connected to the bottom surface of the cylindrical bucket 1. The first end of the connecting rod is connected to the first end of the base frame 4 (it can be a fixed connection or a rotatable connection), and the second end is rotatably connected to the outer wall of the bottom surface of the cylindrical bucket 1. The battery box 5 is vertically placed at the second end of the base frame 4.

[0033] refer to Figure 2 , Figure 3 Two clips 10 are vertically fixed at the bottom of the side opening of the cylindrical bucket 1. The clips 10 are set on the inner wall of the cylindrical bucket 1, and the two clips 10 are arranged opposite each other, close to the two bottom surfaces of the cylindrical bucket 1. The clips 10 have an L-shaped structure, including a vertical side and a horizontal side integrally set at the top of the vertical side. The bottom of the vertical side is integrally connected to the inner wall of the cylindrical bucket, and the first end of the horizontal side is integrally connected to the top of the vertical side. When both clips 10 are installed on the inner wall of the cylindrical bucket 1, the second end of the horizontal side of both clips 10 faces the inner wall of the first bottom surface of the cylindrical bucket 1. A limiting groove 11 is vertically set on the shovel plate 2 at the corresponding position of the clips 10. The size of the limiting groove 11 is adapted to the size of the clips 10. An installation port is also set at the bottom of the opening of the cylindrical bucket 1, which penetrates the first bottom surface of the cylindrical bucket 1. A limiting rotating plate 9 is rotatably set on the outer side of the first bottom surface of the cylindrical bucket 1, and the limiting rotating plate 9 is set outside the installation port.

[0034] During use, the road cleaning device is horizontally fixed to the front of a cleaning vehicle or other large vehicle. After the device is fixed, the vehicle is started and moved horizontally on the road. The vehicle pushes the two tires 3 on the side of the base frame 4 to rotate, thereby driving the cylindrical hopper 1 to move in the same direction. When large garbage that ordinary cleaning vehicles cannot handle appears on the road, the shovel 2 located at the bottom of the opening of the cylindrical hopper 1 contacts the garbage, lifts the garbage from the bottom, and pushes it into the cylindrical hopper 1 with the help of the vehicle's movement, thus completing the cleaning work.

[0035] When installing the shovel plate 2, first rotate the limiting rotating plate 9 to expose the installation opening on the first bottom surface of the cylindrical bucket 1. Then, horizontally insert the new shovel plate 2 into the cylindrical bucket 1 from the installation opening and press it down so that the buckle 10 is vertically inserted into the limiting groove 11 of the shovel plate 2. Then, push the shovel plate 2 horizontally so that the L-shaped buckle 10 moves horizontally along the limiting groove 11, so that the horizontal edge above the L-shaped buckle 10 is locked onto the top of the shovel plate 2. Finally, rotate the limiting rotating plate 9 to cover the installation opening on the first bottom surface of the cylindrical bucket 1 and limit and fix the shovel plate 2, thereby achieving the fixed installation of the shovel plate 2.

[0036] The shovel plate 2 and the cylindrical bucket 1 are connected by a staggered snap-fit ​​mechanism using a snap-fit ​​mechanism 10, making the installation and disassembly of the shovel plate 2 more convenient and quick. Compared with the traditional bolt connection method, the snap-fit ​​connection between the shovel plate 2 and the cylindrical bucket 1 allows the shovel plate 2 to be more stably connected to the cylindrical bucket 1. During long-term operation, the shovel plate 2 will not loosen relative to the cylindrical bucket 1, which helps to improve the stability of the shovel plate 2 during operation.

[0037] refer to Figure 4 A horizontal mounting groove adapted to the end of the shovel plate 2 is provided on the inner wall of the second bottom surface of the cylindrical bucket 1. The mounting groove is located at the bottom of the second bottom surface. When installing the shovel plate 2 on the cylindrical bucket 1, the limiting groove of the shovel plate 2 passes through the buckle 10 on the cylindrical bucket 1. After the shovel plate 2 is pushed horizontally, the right side of the shovel plate 2 ( Figure 2 , Figure 4 The right end of the shovel plate 2 is horizontally inserted into the mounting groove at the bottom of the second bottom surface of the cylindrical bucket 1, thereby making the installation of the shovel plate 2 more stable.

[0038] refer to Figures 1-3 A stop block is horizontally installed at the bottom of the limiting rotating plate 9, and the stop block is horizontally fixed to the bottom of the opening of the first bottom surface of the cylindrical bucket 1. The stop block blocks the bottom of the limiting rotating plate 9, so that the limiting rotating plate 9 can only rotate 180 degrees, thereby providing space for the normal operation of the limiting rotating plate 9.

[0039] refer to Figure 1 The top of each of the two bottom surfaces (first bottom surface and second bottom surface) of the cylindrical bucket 1 is provided with an external interface 8 for moving the cylindrical bucket 1, and the external interface 8 is provided with a through hole. When installing or moving the cylindrical bucket 1, the hook of a large crane can be inserted into the through hole of the external interface 8 of the cylindrical bucket 1, thereby moving the cylindrical bucket 1 by means of the crane.

[0040] A hydraulic rod 7 is also provided on the connecting rod between the tire 3 and the cylindrical hopper 1. One end of the hydraulic rod 7 is connected to the connecting rod, and the other end is connected to the outer wall of the bottom surface of the cylindrical hopper 1. When there is too much garbage inside the cylindrical hopper 1 and the weight increases, the hydraulic rod 7 will slowly contract under the influence of pressure, thereby playing a buffering role.

[0041] A push rod 6 is horizontally positioned between the battery box 5 and the cylindrical bucket 1. The first end of the push rod 6 is located on the top of the battery box 5 and is rotatably connected to the battery box 5. The second end of the push rod 6 is rotatably connected to the side of the cylindrical bucket 1. When the user needs to adjust the angle of the opening of the cylindrical bucket 1, the battery box 5 starts to work, energizing the push rod 6. This causes the push rod 6 to retract or extend, thereby pulling or pushing the cylindrical bucket 1 to rotate, thus changing the angle of its opening.

[0042] The mounting plate on the side of the battery box 5 has multiple horizontal mounting holes, which are evenly distributed in a rectangular shape. When installing the road cleaning device, the bolts are inserted horizontally into the mounting holes, and the road cleaning device is installed on the front of the cleaning vehicle or other large vehicle by rotating and tightening the bolts, thus fixing the road cleaning device in place.

[0043] The road cleaning device of the present invention is mainly applicable to the cleaning of large garbage (such as glass, metal parts, tires, soil and gravel, etc.) on highways. It is not only applicable to the cleaning of ordinary roads, but also to the cleaning of highway roads.

[0044] The above description is merely a detailed illustration of specific embodiments of the present invention and is not intended to limit the invention. Various substitutions, modifications, and improvements made by those skilled in the art without departing from the principles and scope of the present invention should be included within the protection scope of the present invention.
