Description

Technical Field

[0001] This utility model relates to the field of water conservancy, and in particular to a road drainage ditch cleaning device. Background Technology

[0002] The dam area's roads are mostly located in mountainous and hilly areas, with the mountains consisting largely of fractured limestone and shale. During the rainy season, landslides and debris blockages in road drainage ditches are common, leading to roadbed damage, secondary geological disasters, and compromised traffic safety. Therefore, timely cleaning of roadside ditches is crucial. Problems encountered before implementation included: First, using wheeled excavators to clean ditches was difficult because the ditches were narrow on the mountainside, preventing them from crossing them. Furthermore, the bucket and ditch were not aligned, resulting in difficult, inefficient, and time-consuming operations. Second, the cleaning effect with wheeled excavators was unsatisfactory, leaving behind a significant amount of mud, requiring secondary manual cleaning and increasing labor costs. Third, the misalignment of the excavator bucket and ditch made it easy to damage the ditch walls during operation. Additionally, the downward digging method of the excavator, with its obstructed view and difficulty in controlling the digging depth, easily damaged the ditch floor. Utility Model Content

[0003] This utility model provides a road drainage ditch cleaning device, which solves the problem of cleaning road drainage ditches in dam areas.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a road drainage ditch cleaning device, including a small bucket set on one side of the lower end of a large bucket, a connecting positioning plate between the large bucket and the small bucket, positioning grooves on the sides of the large bucket and the small bucket that are close to each other, the two sides of the connecting positioning plate being respectively inserted into the positioning grooves, the positioning grooves having multiple through holes, the connecting positioning plate having connecting bolts, the two ends of the connecting bolts passing through the through holes of the large bucket and the small bucket, the two ends of the connecting bolts being fitted with threaded locking nuts, and each locking nut abutting against the side wall of the large bucket and the small bucket respectively.

[0005] In the preferred embodiment, a back plate is provided on the side of the large bucket and small bucket away from the connecting positioning plate, and a locking nut is provided on the back plate, which can be rotated.

Detailed Implementation

[0020] Example 1:

[0021] like Figure 1-6A road drainage ditch cleaning device includes a small bucket 2 located on one side of the lower end of a large bucket 1. A connecting positioning plate 5 is provided between the large bucket 1 and the small bucket 2. Positioning grooves 6 are provided on the sides of the large bucket 1 and the small bucket 2 that are close to each other. The two sides of the connecting positioning plate 5 are respectively inserted into the positioning grooves 6. Multiple through holes 601 are provided in the positioning grooves 6. The connecting positioning plate 5 is provided with connecting bolts 3. The two ends of the connecting bolts 3 pass through the through holes 601 of the large bucket 1 and the small bucket 2. Threaded locking nuts 4 are fitted on both ends of the connecting bolts 3. Each locking nut 4 abuts against the side wall of the large bucket 1 and the small bucket 2 respectively.

[0022] Positioning grooves 6 are provided on the outer sides of both sides of the large bucket 1 and the outer sides of both sides of the small bucket 2. Depending on the location of the side ditch, the small bucket 2 can be installed on the left or right side of the large bucket 1. The connecting positioning plate 5 is inserted into the positioning groove 6. In addition to quick positioning, it can also resist the torque during excavation and prevent the connecting bolts 3 from being damaged by shearing force.

[0023] During installation, use a jack to raise the lower end of the large bucket 1 to a certain height, ensuring that the positioning groove 6 of the small bucket 2 is approximately at the same height as the positioning groove 6 of the large bucket 1. Insert one end of the connecting bolt 3 on the connecting positioning plate 5 into the through hole 601 of the large bucket 1. After the connecting positioning plate 5 is engaged in the through hole 601 of the large bucket 1, tighten the locking nut 4 on the inner wall of the large bucket 1. Then align the through hole 601 of the small bucket 2 with the other end of the connecting bolt 3, and push the small bucket 2 horizontally to insert the connecting bolt 3 into the through hole 601. After the connecting positioning plate 5 is engaged in the through hole 601 of the small bucket 2, tighten the locking nut 4 on the other end of the connecting bolt 3, thus fixing the large bucket 1 and the small bucket 2 together.

[0024] In the preferred embodiment, a back plate 7 is provided on the side of the large bucket 1 and the small bucket 2 away from the connecting positioning plate 5, and a locking nut 4 is provided on the back plate 7. The locking nut 4 is rotatable.

[0025] Since the large bucket 1 and the small bucket 2 are usually transported separately, the loose locking nuts 4 are easily lost.

[0026] The locking nut 4 is integrated with the back plate 7 to prevent the locking nut 4 from being lost.

[0027] In the preferred embodiment, the back plate 7 is provided with multiple recesses 701, and one end of the locking nut 4 is provided with a circular part 401. The circular part 401 is rotatably sleeved with the recesses 701. Each locking nut 4 on the back plate 7 is provided with a threaded hole 702 on one side. The threaded hole 702 is provided with a threaded clamping limit screw 8. The clamping limit screw 8 is provided with a large diameter part 801, and the large diameter part 801 clamps the circular part 401.

[0028] The clamping limit screw 8 can be screwed out a certain distance, allowing the locking nut 4 to move a short distance in the countersunk groove 701, making it convenient to tighten the locking nut 4. After the locking nut 4 is locked, tightening the clamping limit screw 8 will press the locking nut 4 to prevent loosening.

[0029] When storing, tighten the limiting screw 8 to press the circular part 401 into the sink 701 to prevent loss.

[0030] In a preferred embodiment, the depth of the settling groove 701 is less than the thickness of the circular portion 401.

[0031] The diameter of the circular portion 401 of the locking nut 4 is larger than that of the locking nut 4 body, and the circular portion 401 protrudes from the countersunk groove 701, so that the limiting screw 8 can be easily pressed against the edge position.

[0032] In a preferred embodiment, the end face of the circular portion 401 is provided with a plurality of friction grooves 402 along the circumference, which increases the friction on the bottom surface and improves the anti-loosening ability of the locking nut 4.

[0033] In the preferred embodiment, the connecting positioning plate 5 is provided with multiple connecting holes 501, the connecting bolt 3 is provided with a sleeve part 301 in the center, and the sleeve part 301 is provided with screw parts 302 at both ends, and the sleeve part 301 is sleeved with the connecting hole 501.

[0034] The socket 301 can be threaded to the connecting hole 501 or other detachable connection methods, which makes it easier to reduce the difficulty of processing.

[0035] In the preferred embodiment, the sleeve part 301 is slidably sleeved with the connecting hole 501. The sleeve part 301 is provided with a flat groove part 303, and the side wall of the connecting hole 501 is provided with a threaded set screw 9. One end of the set screw 9 is pressed against the flat groove part 303.

[0036] The bottom of the flat groove 303 is flat, and the set screw 9 abuts against the bottom of the flat groove 303 to prevent the sleeve 301 from rotating when the locking nut 4 is tightened.

[0037] Example 2:

[0038] A road drainage ditch cleaning device is proposed to improve the efficiency of road drainage ditch cleaning operations and ensure that the ditches are not damaged during the operation. Based on the analysis of the on-site environment and working conditions of road drainage ditch cleaning operations, a small road drainage ditch cleaning device combining a loader and a wheeled excavator is designed and manufactured for road drainage ditch cleaning work. This device involves installing a small excavator bucket on the side of the loader bucket. Utilizing the width of the loader bucket, the small excavator bucket is kept aligned with the road ditch during operation. The pre-installed height of the excavator bucket meets the common ditch depths in the construction area, protecting the ditch from damage, improving the quality and efficiency of the cleaning operation, reducing manpower input, and quickly restoring the drainage function of the ditch, thus reducing roadbed damage.

[0039] Two holes with a diameter of 2.4cm are drilled on the left side of the 30cm wide bucket, and the existing connecting holes are modified into two holes with a diameter of 2.4cm, forming one hole at the top and three holes at the bottom, with the three holes at the bottom spaced 12cm apart.

[0040] Following the layout of the bucket holes, drill four holes with a diameter of 2.4cm on the side wall of the loader bucket, forming the same arrangement. Since most road drainage ditches are 50cm deep, for this application scenario, the drilling and positioning of the top hole must ensure that the bucket digs to a depth of ≤50cm after installation.

[0041] The 30cm wide bucket is fixed to the right side of the loader using high-strength bolts (M20*12), thus completing the construction of the small drainage ditch cleaning device. Before use, the tightness and angle of the bolts should be checked and adjusted to ensure safety and reliability before operation.

[0042] When carrying out ditch cleaning operations, first drive the loader to the left side of the road drainage ditch, then place the bucket close to the top edge of the drainage ditch so that the small bucket 2 can be smoothly placed inside the drainage ditch and kept at a certain distance from the bottom of the ditch. Then, the loader slowly moves forward along the edge of the ditch and controls the working depth of the small bucket 2 and the left and right distance between the two sides of the ditch wall so that it can carry out the cleaning operation according to the movement trajectory of the loader.

[0043] The operation is simple and convenient, saving time and labor. When cleaning drainage ditches, the loader can control the small bucket and ensure that it remains aligned with the center line of the ditch during operation. The loader only needs to operate along the road track. It is estimated that, taking the cleaning of a 50m drainage ditch as an example, the current device can reduce the operation time by half an hour compared to a wheeled excavator, effectively improving work quality and efficiency.

[0044] Reduced manpower input. Previously, wheeled excavators were used for cleaning, which not only failed to clean the surface thoroughly but also required four workers to assist in the cleaning. The new equipment only requires one worker to clean the road surface, significantly reducing labor input.

[0045] During the operation, ensure that the side ditches are not damaged and quickly restore their drainage function to prevent secondary road disasters.

[0046] The road drainage ditch cleaning device can be aligned with the center line of the ditch and can automatically control the cleaning depth and lateral spacing.

[0047] The road drainage ditch cleaning device consists of a loader bucket and a small excavator bucket, which are connected by high-strength bolts;

[0048] Compared to conventional wheeled excavator cleaning devices, this reduces manual labor and improves the quality of cleaning operations.

[0049] With a simple and practical structure, it is easy to install and disassemble. The spacing effectively improves the quality and efficiency of cleaning work, while ensuring that the ditches are protected from damage.

[0050] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
