Description

Technical Field

[0001] This utility model relates to the field of drainage ditch cleaning, specifically to a road arc-shaped drainage ditch cleaning device. Background Technology

[0002] Road drainage ditches, as important road infrastructure, are mainly used to quickly drain water from the road surface, prevent water seepage from affecting the stability of the roadbed, and avoid water accumulation affecting vehicle driving safety. During long-term use, silt, fallen leaves, and other impurities will continuously accumulate at the bottom of the drainage ditch, especially in drainage ditch structures with curved bottoms, where these impurities are more likely to deposit on the curved surface of the ditch bottom.

[0003] Existing technologies typically employ excavators for cleaning drainage ditches. However, the flat structure of a traditional excavator bucket makes it difficult to fully conform to the curved bottom of the ditch, leading to the following problems during the cleaning process: First, impurities at the edges of the curved ditch bottom cannot be completely scooped up, creating cleaning dead zones; second, impurities are easily pushed to the sides of the ditch bottom during cleaning, exacerbating their accumulation; and third, repeated cleaning operations can damage the curved structure of the drainage ditch, affecting its drainage efficiency. These problems severely impact the drainage efficiency and service life of the drainage ditches. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a road arc-shaped drainage ditch cleaning device.

[0005] This utility model is achieved through the following technical solution:

[0006] This application provides a road arc-shaped drainage ditch cleaning device, including an excavator bucket, a forward-extending tire installed at the front back of the bucket, the upper part of the tire being fixed to the upper end of the bucket by a binding rope, and a support component being provided inside the tire, which is connected and fixed to the digging teeth at the front end of the bucket by a connecting rope.

[0007] Furthermore, this application also proposes that the upper end of the binding rope be fixed to the connecting ear provided inside the excavator bucket, and the lower part of the binding rope be fixedly connected to the upper end of the tire.

[0008] Furthermore, this application also proposes that the support component includes a built-in support frame, with arc-shaped plates fixed on both sides of the built-in support frame to support the inner walls of both sides inside the tire, and multiple connecting rods arranged longitudinally on the built-in support frame, with the connecting rods being fixedly connected to the corresponding digging teeth by connecting ropes.

[0009] Furthermore, this application also proposes that the lower part of the tire extends to the outside of the bottom end of the bucket, which is 1 / 4 to 1 / 3 of its diameter.

[0010] Furthermore, this application also proposes that the built-in support frame is supported at the central hole in the tire, which can form a barrier to the internal central hole to prevent impurities from leaking out.

[0011] Furthermore, this application also proposes that the binding rope and connecting rope be made of rigid metal wire or metal wire rope.

[0012] Compared with existing technologies, the beneficial effects of this utility model are: by setting tires and support components on the bucket, the device can completely fit the bottom of the arc-shaped ditch, effectively solving the problem that traditional excavator buckets are difficult to clean the bottom of arc-shaped ditches, and has the characteristics of effectively cleaning arc-shaped drainage ditches without damaging the ditch structure.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1-4 As shown, this application proposes a road arc-shaped drainage ditch cleaning device, including an excavator bucket, a forward-extending tire installed at the front of the back of the bucket, the upper part of the tire being fixed to the upper end of the bucket by a binding rope, and a support component being provided on the inner side of the tire, which is connected and fixed to the digging teeth at the front end of the bucket by a connecting rope.

[0020] Hollow, recycled tires can be used, with a diameter ranging from 600-1000mm. The binding rope can be made of metal chain, wire, or steel cable, and its length should be adjusted according to the bucket size to ensure the tire forms a 15-30 degree angle with the ground. The connecting rope is preferably a steel cable with a diameter of 8-12mm, secured to the root of the digging teeth using a U-shaped buckle. A small bucket with a capacity of 0.4-0.6 cubic meters should be selected.

[0021] This device achieves impurity removal through line contact between the tire and the curved bottom of the ditch, increasing the contact area by 3-5 times compared to the point contact method of traditional buckets. The support assembly evenly distributes the force on the tire to the bucket frame, avoiding localized stress concentration. The binding ropes and connecting ropes form a triangular stabilizing structure, maintaining the tire at a predetermined tilt angle during operation. Actual testing shows that this device improves the cleaning efficiency of curved drainage ditches with a radius of 300-500mm by more than 40%, with residual impurities not exceeding 20mm in thickness.

[0022] Furthermore, this application also proposes that the upper end of the binding rope be fixed to the connecting ear provided inside the excavator bucket, and the lower part of the binding rope be fixedly connected to the upper end of the tire.

[0023] Specifically, the connecting lug can be fixed to the back of the bucket by welding, and its structure is preferably a ring-shaped part. The fixing methods between the binding rope and the connecting lug include, but are not limited to: connection via metal hooks, and connection using a quick-release snap-fit ​​structure. The binding rope is directly threaded through the tire for securing.

[0024] Therefore, this technical solution achieves a reliable connection between the binding rope and the bucket through the connecting lugs, while ensuring that the tires maintain a stable posture during operation. Compared with the method of directly binding it to the outside of the bucket, this structure can effectively distribute the force and prevent the binding rope from shifting or loosening during operation.

[0025] Furthermore, this application also proposes that the support component includes a built-in support frame, with arc-shaped plates fixed on both sides of the built-in support frame to support the inner walls of both sides inside the tire, and multiple connecting rods arranged longitudinally on the built-in support frame, with the connecting rods being fixedly connected to the corresponding digging teeth by connecting ropes.

[0026] The built-in support frame can be a metal frame structure, its shape matching the curvature of the tire's inner wall. The radius of curvature of the curved plate can be adjusted for different tire sizes; for example, a detachable curved plate design can be used to accommodate various tire sizes. Connecting rods can be arranged at equal intervals, with a recommended spacing range of 15-30cm, determined based on the density of the cutting teeth. The fixing methods between the connecting rope and the cutting teeth include, but are not limited to, collar connections and snap-fit ​​connections. As a preferred embodiment, the built-in support frame can be designed as an adjustable-length structure, allowing for dynamic adjustment of the support force through telescopic rods.

[0027] This technical solution effectively enhances the stability of the tire structure and prevents deformation during cleaning operations through the cooperation of the built-in support frame and the arc-shaped plate. The arrangement of multiple connecting rods makes the force distribution more even, and through linkage and fixation with the digging teeth, it ensures both the integrity of the cleaning device and the effective transmission of force during operation. Compared with existing technologies that lack a support structure, this design significantly improves the cleaning efficiency of impurities at the bottom of the arc-shaped drainage ditch while reducing the risk of equipment damage. Specifically, the tight fit between the arc-shaped plate and the inner wall of the tire prevents impurities from entering the tire, while the longitudinal connecting rods form a stable force transmission path, allowing the digging teeth to act more precisely on the bottom of the arc-shaped ditch.

[0028] Furthermore, this application also proposes that the lower part of the tire extends to the outside of the bottom end of the bucket, which is 1 / 4 to 1 / 3 of its diameter.

[0029] Specifically, the tire extension length is set considering the following factors: Insufficient extension will result in insufficient contact area between the tire and the drainage ditch, affecting cleaning efficiency; excessive extension may cause excessive stress on the connection structure between the tire and the bucket. By controlling the extension within 1 / 4 to 1 / 3 of the tire diameter, optimal contact between the tire and the bottom of the curved drainage ditch can be ensured. As a preferred implementation, the extension can be 1 / 3 of the diameter, maximizing the contact area between the tire and the ditch bottom; or 1 / 4 of the diameter, resulting in a more balanced stress on the connection structure.

[0030] Therefore, the working principle of this technical solution is as follows: by precisely controlling the extension length of the tire, the tire can fully contact the bottom of the arc-shaped drainage ditch while ensuring the stability of the connection structure. Compared with existing technologies, this solution solves the technical problem that the excavator bucket cannot fully conform to the bottom of the arc-shaped ditch, allowing impurities to be effectively cleaned. Specifically, when the tire extends to the set extension amount, its outer edge can closely adhere to the arc surface of the ditch bottom, completely scraping up impurities during the movement of the bucket; at the same time, because the extension amount is scientifically calculated, deformation or breakage of the connecting parts due to excessive extension is avoided.

[0031] Furthermore, this application also proposes that the built-in support frame is supported at the central hole of the tire, which can form a barrier at the internal central hole to prevent impurities from leaking out.

[0032] The technical solution of this application solves the problem of material leakage from the tire's center hole during the cleaning of arc-shaped drainage ditches by using a built-in support frame to block the leakage. Specifically, when the bucket is cleaning within the arc-shaped drainage ditch, the built-in support frame completely covers the tire's center hole area, forming an effective physical barrier. Compared with existing technologies, this solution significantly improves the integrity and efficiency of impurity removal, avoiding repeated cleaning operations due to material leakage. Furthermore, this design is simple and reliable, achieving leak-proof functionality without the need for an additional power unit, and possesses good practicality and economy.

[0033] Furthermore, this application also proposes that the binding rope and connecting rope be made of rigid metal wire or metal wire rope.

[0034] Specifically, rigid metal wire refers to a thread-like material made of metal with a certain degree of rigidity and strength, capable of withstanding significant tensile and bending forces. Metal wire rope, on the other hand, is made of multiple strands of twisted metal wire, offering higher strength and wear resistance. The choice between these two materials can be determined based on the actual usage environment and stress requirements. For example, metal wire rope can be used in applications requiring higher strength and wear resistance; while rigid metal wire is sufficient under normal stress conditions. As a preferred embodiment, the surface of the metal wire or wire rope can be treated with rust prevention to extend its service life.

[0035] Therefore, using rigid metal wire or steel wire rope as the binding and connecting rope material can effectively improve the stability and durability of the entire device. Because metal materials have high strength and tensile properties, they ensure a secure connection between the tires and the bucket, preventing connection failure due to excessive stress during cleaning. At the same time, the wear resistance of metal materials can withstand the friction and impact of impurities in the drainage ditch, reducing the frequency of maintenance and replacement. Therefore, this technical solution solves the problems of easily damaged connecting parts and insufficient stability in existing technologies, improving the efficiency and reliability of cleaning operations.

[0036] The implementation principle of a waterproof cable trench in this application embodiment is as follows:

[0037] First, place the tire 3 on the back of the bucket 1, and place the built-in support frame 6 of the support assembly inside the tire 3, so that the arc plates 8 on both sides support the two ends inside the tire 3. Then, use the binding rope 4 to tie it to the connecting lug 5 on the back of the bucket 1 to fix the upper part of the tire 3. Then, tie multiple connecting ropes 9 to the connecting rod 7 of the corresponding digging teeth 2 and the built-in support frame 6 to bind the support assembly to the digging teeth 2, so that the tire 3 is stably fixed on the back of the bucket 1. Operate the excavator to align the tire 3 at the bottom of the bucket 1 with the bottom of the drainage ditch 10 to achieve contact, and move it to remove the impurities. The removed impurities enter the bucket 1 for cleaning, which makes cleaning impurities more convenient and efficient.
