Description

Technical Field

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

[0002] Potholes are considered a common problem encountered by highways or urban roads during long-term use. They are generally caused by heavy vehicle pressure, rainwater erosion, and aging of materials. They form potholes by breaking and sinking in a certain part of the road surface. If they are not repaired in time, the road surface will be more severely damaged, the vehicle will lack stability, and the road section may cause accidents. Based on the inventor's knowledge, the core technologies relied upon by the road pothole milling device closest to this technical solution are as follows: the main body is a rigid frame structure, with milling components fixed at the bottom. Generally, a drive motor is used to drive the milling cutter head or a fixed cutter head to complete the milling. The installation angle of the cutter head is fixed and cannot be adjusted to multiple angles, thus it is only suitable for vertical milling operations. The cutter head itself is a straight-edged structure arranged according to the principle of equal spacing, and the cutter body material is mostly conventional alloy steel without a specially designed drag-reducing structure. The device only considers a single milling module and ignores chip handling. Even with auxiliary brushes, they only have a limited effect on surface dust, and the chips milled out in the pothole are difficult to remove or properly dispose of in a timely manner. At the same time, the device does not include a chip crushing device, and large chips cannot be decomposed again, and can only be sorted and processed by people or additional equipment.

[0003] Existing road pothole milling equipment cannot achieve efficient and precise milling of potholes. The milling component angle is fixed and cannot be flexibly adjusted according to the different depths and inclination angles of the potholes. During milling, dead corners are easily formed, resulting in uneven and unsound bottom surfaces of potholes. In some cases, over-milling can even damage the road base. At the same time, the milling structure design is unreasonable, resulting in high milling resistance and serious debris splashing, which affects milling efficiency and the working environment.

[0004] Secondly, existing equipment cannot achieve integrated milling and cleaning operations. After milling, the milling debris in the potholes needs to be manually cleaned or additional cleaning equipment needs to be provided. This not only greatly increases the labor intensity of operators, but also prolongs the road maintenance period and reduces work efficiency. In addition, some equipment lacks an effective debris crushing structure, making it difficult to clean large debris. The residual debris will affect the bonding between the subsequent repair material and the pothole, reducing the quality of road repair.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a road surface pothole milling and cleaning device, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0009] A milling assembly, comprising a rotary shaft, milling plates, and a drill bit, wherein the milling plates are mounted in a circular array on the outer wall of the rotary shaft;

[0010] A dust removal assembly, comprising a lug and a bucket;

[0011] A pushing assembly is disposed within the assembly frame cavity, and the pushing assembly includes a push plate and a shaft.

[0012] According to the road surface pothole milling and cleaning device, the milling plate is inclined, the outer wall of the milling plate is provided with a groove, the rotating shaft is fixedly connected through the milling plate and fixedly connected to the drill bit, and multiple sets of blades are fixedly connected to the outer wall of the drill bit.

[0013] According to the road surface pothole milling and cleaning device, the top of the assembly frame is provided with a mounting base, the rotary motor is fixedly installed on the top surface of the mounting base, the output shaft of the rotary motor movably passes through the mounting base and is fixedly installed through the rotating ring inside the assembly frame cavity, the rotating ring is fixedly installed inside the assembly frame cavity, and the assembly frame and the rotating ring are driven to rotate by the rotary motor.

[0014] According to the aforementioned road surface pothole milling and cleaning device, a first mounting plate is also fixedly installed inside the assembly frame cavity, an electric telescopic rod is fixedly installed on the bottom surface of the first mounting plate, and a blade is also fixedly installed inside the assembly frame cavity. The blade is located below the first mounting plate, and the telescopic end of the electric telescopic rod movably passes through the blade.

[0015] According to the road surface pothole milling and cleaning device, there are two sets of push plates, and a rectangular connecting plate is fixedly installed between the two sets of push plates. An arc-shaped clearance groove is opened on one side of the push plate, and the shaft is fixedly installed at one end between the two sets of push plates.

[0016] According to the road surface pothole milling and cleaning device, a servo motor is provided in the assembly frame cavity, and a main shaft is fixedly installed on both sides of the servo motor. The main shaft movably passes through both sides of the assembly frame, and the servo motor is movably installed in the assembly frame cavity through the main shaft. The output shaft of the servo motor is fixedly connected to the rotating shaft through a coupling.

[0017] According to the road surface pothole milling and cleaning device, a lug is fixedly installed at the rear end of the servo motor, the lug is located between two sets of push plates, and the shaft moves through the lug.

[0018] According to the road surface pothole milling and cleaning device, the telescopic end of the electric telescopic rod is movably mounted on one end of the two sets of push plates away from the shaft via a pin.

[0019] According to the road surface pothole milling and cleaning device, the two ends of the ear plate are movably installed at both ends of the main shaft. The ear plate is L-shaped, and the bucket is fixedly installed at the other end of the ear plate to remove ash.

[0020] Compared with the prior art, the road surface pothole milling and cleaning device provided by the present invention has the following beneficial effects:

[0021] 1. In this invention, efficient and precise milling of road potholes can be achieved, adapting to the milling needs of potholes of different specifications. After the servo motor is started, its output shaft drives the rotating shaft to rotate at high speed through the coupling. The rotating shaft drives the milling plate and drill bit to rotate synchronously. The multiple sets of blades on the drill bit can quickly break through the hard damaged layer at the bottom of the pothole. The inclined milling plate can push the milling debris outward. The groove on the milling plate can reduce milling resistance and reduce debris splashing. At the same time, the electric telescopic rod can push the push plate to rotate around the shaft, driving the servo motor and milling components to flexibly adjust the angle to adapt to potholes of different depths and angles, ensuring that the bottom surface of the pothole after milling is flat and solid, avoiding milling dead corners and over-milling.

[0022] 2. This invention enables integrated milling and cleaning of potholes, significantly improving road maintenance efficiency and reducing manual labor intensity. The rotary motor drives the assembly frame and rotating ring to rotate synchronously, causing the milling and shoveling components to rotate together. After the milling operation is completed, the L-shaped lugs drive the bucket to rotate synchronously with the main shaft, reaching deep into the bottom and edge of the pothole to shovel up and clean all the debris, eliminating the need for manual cleaning. At the same time, the baffles can prevent milling debris from splashing, and the blades inside the cavity can further crush large particles of debris, facilitating bucket cleaning. All components of the device are securely connected, and the main shaft, lugs, and other parts ensure stable operation, allowing for long-term and stable milling and cleaning operations, laying a good foundation for subsequent road repairs.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] like Figure 1-8 As shown, the present invention is a road surface pothole milling and cleaning device, including an assembly frame 10, which is U-shaped, a rotary motor 13 is provided at the top of the assembly frame 10, and baffles 14 are fixedly installed on both sides of the assembly frame 10.

[0037] Regarding the assembly frame 10, it adopts a U-shaped structure, which is both compact and sturdy. It serves as the main installation foundation for the entire device, providing ample support for various components such as the rotary motor 13, the milling section 11, and the pushing assembly 15. This ensures that each component is properly positioned and well-matched. The U-shaped structure is also suitable for the shape of road potholes, facilitating the milling assembly 11 or the shovel assembly 12 to completely fill and thoroughly treat the potholes, thus expanding the working area. The rotary motor 13 is the power center of the device, driving the relevant components to rotate and automatically complete the pothole milling without relying on direct manual control. Therefore, it is highly efficient, saves manpower, and reduces the workload of the operator. The baffles 14 are installed on both sides of the assembly frame 10. During the milling operation, they can confine the flying gravel and dust to a certain area, preventing debris from interfering with the road surface or workers. At the same time, they physically prevent gravel from damaging the device itself, providing a protective function and helping to extend its service life.

[0038] The top of the assembly frame 10 is provided with a mounting base 16. The rotary motor 13 is fixedly installed on the top surface of the mounting base 16. The output shaft of the rotary motor 13 moves through the mounting base 16 and is fixedly installed through the rotating ring 17 inside the cavity of the assembly frame 10. The rotating ring 17 is fixedly installed inside the cavity of the assembly frame 10. The assembly frame 10 and the rotating ring 17 are driven to rotate by the rotary motor 13.

[0039] Specifically, the mounting base 16 is a sturdy fixing device for the rotary motor 13, ensuring that the rotary motor 13 does not wobble significantly and its installation is stable, preventing vibration from interfering with the milling accuracy. It also provides good support for the output shaft, preventing deformation and breakage. The output shaft of the rotary motor 13 passes through the mounting base 16 and the rotating ring 17. Combined with the two, it ensures that power transmission is efficient and drives the assembly frame 10 and the rotating ring 17 to rotate smoothly together. This drives the milling part 11 and the shoveling part 12 to rotate synchronously, so that all parts of the pit are milled, leaving no uncleaned edges or corners, resulting in better cleaning effect. The rotating ring 17 is a fixed component inside the cavity of the assembly frame 10, which strengthens the structure of the assembly frame 10, prevents deformation during rotation, and facilitates the transmission of rotational power, allowing the assembly frame 10 to operate continuously and maintaining the continuity of the operation.

[0040] The milling assembly 11 includes a rotating shaft 20, a milling plate 21, and a drill bit 23. The milling plate 21 is mounted in a ring array on the outer wall of the rotating shaft 20. The milling plate 21 is inclined and has a groove 22 on its outer wall. The rotating shaft 20 is fixedly inserted through the milling plate 21 and fixedly connected to the drill bit 23. Multiple sets of cutting blades 24 are fixedly connected to the outer wall of the drill bit 23.

[0041] In terms of specific structure, the milling assembly 11 is the basic execution device for pothole milling, which can quickly process damaged or loose road surface and aggregate in potholes and make necessary preparations for the surface before repair. The milling plate 21 is mounted on the outer wall of the rotating shaft 20 in a ring manner, which can make the applied milling force more uniform and not miss any part of the pothole (including the inner wall and bottom). The inclined structure is conducive to increasing the milling strength and will not allow debris to be trapped inside the pothole and hinder the milling progress. The groove 22 plays a role in limiting the area of ​​the milling plate 21, so that the contact surface is not too large, thus reducing the resistance. The debris can also be partially contained and is not easy to splash, thus ensuring the milling efficiency. The drill bit 23 is a fixed part of the rotating shaft 20. With the help of the high-speed rotation of the shaft, it can effectively enter the bottom of the pothole and remove hard broken materials. The multi-blade insert 24 is an auxiliary means of milling, which helps to increase the speed and adapt to the needs of road surfaces of various hardness. The bottom surface of the pothole will be relatively flat and solid.

[0042] A first mounting plate 25 is also fixedly installed inside the cavity of the assembly frame 10. An electric telescopic rod 26 is fixedly installed on the bottom surface of the first mounting plate 25. A blade 24 is also fixedly installed inside the cavity of the assembly frame 10. The blade 24 is located below the first mounting plate 25. The telescopic end of the electric telescopic rod 26 can move through the blade 24.

[0043] Specifically, the first mounting plate 25 serves as a reliable mounting base for the electric telescopic rod 26, ensuring its vertical and non-tilted positioning for accurate extension and retraction. This also contributes to the structural stability of the assembly frame 10, preventing any shaking of parts within the cavity. The telescopic force provided by the electric telescopic rod 26 is a reliable power source, enabling the push assembly 15 to automatically complete its movements without manual control, thus improving operational convenience. The blade 24, installed inside the cavity of the assembly frame 10 and below the first mounting plate 25, can perform a second cutting process on large debris generated during milling, reducing it to smaller particles. This facilitates subsequent cleaning by the shovel assembly 12 and prevents coarse debris from damaging equipment or soiling the surrounding road surface. The telescopic end of the electric telescopic rod 26 passes through the blade 24 without contacting it, ensuring unobstructed movement and coordinated operation of all involved components.

[0044] The push assembly 15 is disposed in the cavity of the assembly frame 10. The push assembly 15 includes a push plate 28 and a shaft 31. There are two sets of push plates 28, and a rectangular connecting plate 30 is fixedly installed between the two sets of push plates 28. An arc-shaped clearance groove 29 is opened on one side of the push plate 28, and the shaft 31 is fixedly installed at one end between the two sets of push plates 28.

[0045] According to the specific description, the push assembly 15 is used to drive the servo motor 32 and the milling assembly 11 to change the angle, which can adapt to the needs of milling grooves of various depths or angles and improve the adaptability of the device. The two sets of push plates 28 are symmetrically arranged and will not be tilted due to uneven force. The rectangular connecting plate 30 connects the two sets of push plates 28 together, making the structure of the push assembly 15 more robust, the movement more coordinated, and the pushing process easier to control. The arc-shaped clearance groove 29 avoids the push plates 28 from colliding with the components (rotating ring 17, spindle 33) inside the assembly frame 10, and does not hinder their movement, so it has no adverse effect on the normal operation of the device. The shaft 31 is installed between the two sets of push plates 28, which can serve as the rotation axis of the push plates 28 and facilitate the installation of the lug 34. Therefore, it can ensure that the servo motor 32 rotates synchronously with the push plates 28, driving the milling assembly 11 to change the angle and achieve the purpose of precise groove milling.

[0046] A servo motor 32 is installed inside the cavity of the assembly frame 10. A spindle 33 is fixedly installed on both sides of the servo motor 32. The spindle 33 movably passes through both sides of the assembly frame 10. The servo motor 32 is movably installed inside the cavity of the assembly frame 10 through the spindle 33. The output shaft of the servo motor 32 is fixedly connected to the rotating shaft 20 through a coupling.

[0047] Specifically, the servo motor 32 provides precise rotational power to the milling assembly 11, accurately controlling the rotational speed and angle of the rotating shaft 20, thereby controlling the milling force and depth to ensure milling accuracy and avoid over-milling that could damage the road base or incomplete milling. The spindle 33 is fixed on both sides of the servo motor 32 and passes through the mounting frame 10, allowing the servo motor 32 to be movably installed within the cavity of the mounting frame 10, ensuring that the servo motor 32 can rotate flexibly and adjust its angle in conjunction with the push assembly 15. At the same time, the spindle 33 provides stable support for the servo motor 32, preventing it from shaking during operation and ensuring stable power transmission. The coupling connects the output shaft of the servo motor 32 to the rotating shaft 20, enabling smooth power transmission, buffering vibrations during motor operation, preventing vibrations from being transmitted to the rotating shaft 20 and causing the milling assembly 11 to shake, and facilitating later disassembly and maintenance of the milling assembly 11, thus reducing maintenance costs.

[0048] The rear of the servo motor 32 is fixed by a lug 34, which is located in the center of the two push plates 28, through which the shaft 31 can pass.

[0049] Specifically, the lug 34 is a part fixed behind the servo motor 32. It can be used to connect the servo motor 32 and the push plate 28 in a movable connection. After the shaft 31 passes through the lug 34, it becomes the rotating shaft of the servo motor 32, allowing it to rotate flexibly around the shaft 31. The tilt state of the milling assembly 11 is controlled by the movement of the push plate 28, so as to make accurate milling arrangements for the inner wall of the pit at various angles. The lug 34 is sandwiched between the two push plates 28, which helps to make the pressure on the servo motor 32 even and prevent it from tilting during rotation, while also preventing it from moving too freely and causing interference. This ensures that the whole device operates normally, and the milling assembly 11 is always in the most appropriate position, and the milling effect achieved is also more ideal.

[0050] The telescopic part of the so-called electric telescopic rod 26 is mounted on the non-axial side end (i.e. the end away from the shaft 31) of the two sets of push plates 28 by means of a pin.

[0051] In terms of specific construction, the telescopic end of the electric telescopic pole 26 is movably connected to the push plate 28 by a pin. This allows the telescopic power of the electric telescopic pole 26 to drive the push plate 28 to rotate, enabling it to rotate flexibly around the shaft 31. This, in turn, drives the servo motor 32 and the milling assembly 11 to change angles. The structure is simple, the transmission is unobstructed, and no additional drive components are needed, making it a cost-effective design for device manufacturing. The pin connection facilitates the smooth rotation of the push plate 28, preventing it from jamming due to friction, and also absorbs the impact of the telescopic pole 26's extension and retraction, preventing damage to the push plate 28 or the pole due to excessive force. The connection method ensures proper coordination between the movement of the electric telescopic pole 26 and the rotation of the push plate 28, making the milling angle accurately adjustable. This makes it suitable for handling various types and depths of road surface defects, thus possessing high practical value.

[0052] The so-called ash-shoveling assembly 12 consists of ear plates 35 and a bucket 36. The ear plates 35 are movably mounted on both ends of the main shaft 33 and are L-shaped. The bucket 36 is a component fixedly connected to the other end of the ear plates 35 and is used for shoveling ash.

[0053] From a specific perspective, the shovel assembly 12 is a rapid processing device for pothole debris obtained from milling. It prevents debris accumulation from interfering with subsequent road repair work, allowing milling and cleaning to be completed simultaneously, thus greatly improving road maintenance efficiency. The ear plate 35 has an L-shaped structure, which is sturdy and occupies little space. Both ends are mounted on the main shaft 33 in a movable manner and rotate with the rotation of the main shaft 33, thereby driving the bucket 36 to rotate and completely clean the debris in all parts of the pothole. The L-shaped feature also allows the bucket 36 to reach the bottom and edges of the pothole without forming dead corners, ensuring a more thorough cleaning. The bucket 36 is installed at the other end of the ear plate 35, and its shape is suitable for the actual condition of the pothole. It can quickly pick up milled material without wasting time and will not lose debris during shoveling. The cleaning itself is labor-saving and requires less manpower. The cleaned pothole bottom is smooth and free of residue, providing a good foundation for filling with repair agent. The above three points can be regarded as a reasonable combination of the overall design.

[0054] The implementation principle of the road surface pothole milling and cleaning device of the present invention is as follows:

[0055] First, the device is assembled and debugged. The milling component 11, the pushing component 15, and the shovel component 12 are assembled into the cavity of the assembly frame 10 in sequence. Ensure that the rotary motor 13, servo motor 32, electric telescopic rod 26 and other components are installed firmly and connected smoothly. Check the integrity of the milling plate 21, drill bit 23, and bucket 36. Then, move the device to the designated position of the road pothole, align it with the center of the pothole, and complete the preparation work before milling and cleaning.

[0056] Next, the starting device begins the milling operation. First, the rotary motor 13 is started, and its output shaft drives the rotating ring 17 and the assembly frame 10 to rotate synchronously, which in turn drives the milling assembly 11 and the dust removal assembly 12 to rotate together. At the same time, the servo motor 32 is started, and its output shaft drives the rotating shaft 20 to rotate at high speed through the coupling. The rotating shaft 20 drives the milling plate 21 and the drill bit 23 to rotate synchronously. The blades 24 on the drill bit 23 mill the hard and damaged layer at the bottom of the pit. The inclined milling plate 21 pushes the milling debris to the outside. The blades 24 in the cavity perform secondary crushing on the large particles of debris that splash. During this process, the electric telescopic rod 26 can be extended and retracted to push the push plate 28 to rotate around the shaft 31, which drives the servo motor 32 and the milling assembly 11 to adjust the angle to adapt to the milling requirements of different depths and angles of the pit.

[0057] Finally, after the milling operation is completed, the shovel assembly 12 rotates synchronously with the main shaft 33 and the assembly frame 10. The L-shaped ear plate 35 drives the bucket 36 to penetrate deep into the bottom and edge of the pothole, shoveling up all the debris generated by milling and cleaning it out of the pothole, realizing the integrated operation of milling and cleaning. After cleaning is completed, all motors and electric telescopic rods 26 are turned off, and the device is moved to the next pothole position. The above steps are repeated until the milling and cleaning of all road potholes are completed.

[0059] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0060] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.
