Technical Field

[0001] This application relates to the field of waterway dredging technology, and more specifically, to a drainage waterway dredging device. Background Technology

[0002] As a crucial component of urban infrastructure, drainage ditches play a vital role in removing rainwater and sewage, and are essential for maintaining the health and stability of the urban water environment. However, in practical applications, drainage ditches often face problems such as siltation and blockage, which not only affect their drainage efficiency but may also lead to serious consequences such as urban flooding and water pollution.

[0003] Traditionally, the cleaning and maintenance of drainage ditches has relied primarily on manual sludge removal. While this method can address drainage clogging to some extent, it has several drawbacks. First, manual sludge removal is labor-intensive and inefficient, especially when dealing with large-scale accumulations, requiring significant manpower, resources, and time. Second, manual operation poses safety hazards, particularly in inclement weather or complex environments, where worker safety is difficult to guarantee. Furthermore, manual sludge removal struggles to ensure thorough and even cleaning, often leaving blind spots and impacting drainage efficiency.

[0004] To address these issues, the industry has been exploring more efficient and safer methods for cleaning and maintaining drainage ditches. In recent years, with the development of mechanization and automation technologies, some advanced drainage ditches cleaning equipment has emerged. These devices utilize advanced tools such as robotic arms and high-pressure water guns to achieve rapid and efficient cleaning of drainage ditches. However, these devices still have some limitations in practical applications, such as complex operation, high maintenance costs, and limited applicability.

[0005] Therefore, it is necessary to develop a new method for cleaning and maintaining drainage ditches. This method should overcome the shortcomings of traditional manual sludge removal, improve cleaning efficiency and quality, and reduce operational difficulty and maintenance costs. Specifically, this method should enable rapid and efficient cleaning of drainage ditches, ensuring thoroughness and uniformity. Furthermore, it should be easy to operate, safe and reliable, and have low maintenance costs to meet the cleaning needs of drainage ditches of different sizes and types. Utility Model Content

[0006] Based on the above problems, this application proposes a drainage canal dredging device to solve the technical problems of the shortcomings of traditional manual dredging and debris removal, poor cleaning efficiency and quality, and high operation difficulty and maintenance cost.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A drainage canal dredging device includes a mounting frame, a frame mounted on the mounting frame, a rotating screen mounted on the frame, a first motor mounted on the frame to provide power to the rotating screen, a protective shell at the end of the frame, a cleaning roller installed inside the protective shell, the two ends of the rotating shaft of the cleaning roller being rotatably connected to the protective shell, a second motor mounted on one side of the protective shell, the power output end of the second motor being fixedly connected to the rotating shaft of the cleaning roller, a ash receiving hopper below the protective shell, and a conveyor belt below the ash receiving hopper.

[0009] In one specific implementation, the protective shell is provided with an opening, the cleaning roller is located above the opening, and the ash hopper consists of two side plates and a bottom plate, with the bottom plate arranged at an angle.

[0010] In one specific implementation, the conveyor belt is arranged at an angle to the ground, and baffles are installed on the conveyor belt, with at least one baffle provided.

[0011] In one specific implementation, at least one mounting base is mounted on the cleaning roller, and at least one brush is mounted on each of the mounting bases.

[0012] In one specific implementation, the rotary grille is provided with protruding spikes.

[0013] In one specific implementation, the frame is provided with a pivot, at least one pivot, and the rotating grille is wound around the pivot.

[0014] In one specific implementation, the two ends of each of the rotating shafts are rotatably connected to the frame, and the power output end of the first motor is connected to one of the rotating shafts through a transmission box.

[0015] The positive effects of this utility model are:

[0016] By installing a rotary screen and driving it to rotate using a first motor, silt and debris in the canal can be effectively intercepted and cleared. The use of the rotary screen improves dredging efficiency and ensures unobstructed water flow. By installing cleaning rollers and driving them to rotate using a second motor, the brushes on the cleaning rollers can meticulously remove debris adhering to the screen.

[0017] The meticulous cleaning action of the cleaning rollers ensures the continuous and efficient operation of the screen, avoiding incomplete cleaning caused by debris adhesion. The cleaned sludge and debris are collected in a hopper and transported away by an inclined conveyor belt.

[0018] The combined use of the ash hopper and conveyor belt enables the effective collection and transportation of sludge and debris, thus avoiding environmental pollution problems. Attached Figure Description

[0028] like Figure 1-4 As shown, a drainage canal dredging device includes a mounting frame 1, which provides stable support for the entire device. A frame 2 serves as the mounting base for other components, resulting in a robust structure that is easy to install and maintain. The frame 2 is mounted on the mounting frame 1, and a rotating shaft 14 is provided on the frame 2. At least one rotating shaft 14 is provided, and a rotating grille 3 is wound around the rotating shaft 14. The rotating shaft 14 allows the rotating grille 3 to rotate flexibly, facilitating the removal of silt and debris from the canal. The protruding spikes 13 on the rotating grille 3 enhance its cleaning effect.

[0029] A rotating grille 3 is installed on the frame 2, and the rotating grille 3 is provided with protruding spikes 13.

[0030] A first motor 7, which provides power to the rotary grille 3, is mounted on the frame 2. Both ends of each rotating shaft 14 are rotatably connected to the frame 2. The power output end of the first motor 7 is connected to one of the rotating shafts 14 via a transmission box 15. The first motor 7 provides power to the rotary grille 3, while the transmission box 15 serves to transmit power and reduce speed and increase torque.

[0031] A protective shell 4 is provided at the end of the frame 2. A cleaning roller 5 is installed inside the protective shell 4. At least one mounting base 11 is installed on the cleaning roller 5, and at least one brush 12 is installed on each mounting base 11. The design of the protective shell 4 protects the cleaning roller 5 and other components from interference and damage from the external environment. The brushes 12 on the cleaning roller 5 can meticulously clean the silt and debris adhering to the rotary grid 3.

[0032] The protective shell 4 has an opening, the cleaning roller 5 is located above the opening, and the ash hopper 8 consists of two side plates and a bottom plate, with the bottom plate arranged at an angle.
