Description

Technical Field

[0001] This utility model relates to the technical field of cleaning trash racks, and in particular to an automatic trash rack cleaning machine. Background Technology

[0002] In the construction of water conservancy projects and the ecological management of aquatic areas, trash racks, as important auxiliary facilities of hydraulic structures such as hydropower stations, reservoirs, and sluices, primarily function to intercept floating debris such as tree branches, plastic waste, and aquatic plants in the water, preventing these debris from entering the water conveyance system or power generation equipment, thereby ensuring the safe and stable operation of hydraulic structures and machinery. However, with changes in the natural environment and the impact of human activities, the amount of floating garbage in waterways is constantly increasing, and the amount of debris intercepted by trash racks is also growing ever larger.

[0003] Currently, the removal of debris from trash racks mainly employs two methods: manual cleaning and mechanical cleaning. Manual cleaning typically requires workers to approach the trash racks by boat and manually retrieve the debris using tools such as hooks and nets. This method is not only labor-intensive and inefficient, but also poses challenges to the personal safety of workers in situations such as rapid currents or inclement weather. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this utility model provides an automatic cleaning machine for trash racks.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model discloses an automatic trash rack cleaning machine, comprising:

[0007] The suspension seat floats on the water surface.

[0008] The conveyor support is fixedly installed on the suspension seat. The conveyor support is set at an angle on the suspension seat, and a conveyor belt is installed on the conveyor support for transmission.

[0009] Two cleaning supports are symmetrically arranged on both sides of the conveyor support.

[0010] The scraper shaft is rotatably mounted on two cleaning supports.

[0011] The scraper motor is fixedly mounted on one of the cleaning brackets and is used to drive the scraper shaft to rotate;

[0012] The scraper frame and fastening kit are mounted on the scraper shaft. The scraper frame is equipped with four scraper blades, each of which is equipped with scraping teeth.

[0013] The processing unit, located on the suspended platform, is used to receive and process the waste conveyed by the conveyor belt.

[0014] Furthermore, the processing facilities include:

[0015] The mounting bracket is used to securely install the suspension base.

[0016] The processing bucket is fixedly installed on the mounting bracket and is used to receive the waste discharged from the conveyor belt;

[0017] External bracket, fixedly installed on the outer wall of the processing bucket;

[0018] Four rotary cutting components are installed in the processing hopper to rotary cut the conveyed and falling waste.

[0019] Furthermore, the rotary cutting assembly includes:

[0020] The rotary cutting motor is fixedly mounted on an external bracket.

[0021] The rotary cutting shaft is rotatably inserted into the processing hopper and is driven to rotate by a rotary cutting motor.

[0022] Multiple cutters are evenly arranged on the rotary cutting shaft.

[0023] Furthermore, the processing facilities also include:

[0024] The transfer bucket is connected to the bottom of the processing bucket;

[0025] The conveying pipe is connected to the transfer bucket, and a lifting frame is installed on the conveying pipe. The lifting frame is fixedly connected to the external support.

[0026] A conveying assembly, mounted on a conveying pipe, is used to transport shredded waste outwards.

[0027] Furthermore, the transmission component includes:

[0028] A conveyor shaft is rotatably mounted in a conveyor pipe, and spiral blades are spirally arranged on the conveyor shaft;

[0029] The conveyor motor is fixedly installed at the outer end of the conveyor pipe, and a drive wheel is provided at the output end of the conveyor motor.

[0030] The driven wheel is fixedly installed on the outer end of the conveyor shaft, and the driven wheel is driven by the driving wheel through a belt.

[0031] Furthermore, the conveyor belt is equipped with drainage holes.

[0032] Furthermore, each scraper tooth is threadedly inserted into the scraper frame.

[0033] Furthermore, a waterproof cover is installed on the outer end of the scraper motor.

[0034] The automatic trash rack cleaning machine provided by this utility model, as described above, has the following beneficial effects:

[0035] Compared to manual retrieval of debris using hooks and nets, this automatic debris removal machine, driven by a scraper motor, rotates the scraper shaft and frame, enabling continuous automatic operation. This significantly improves cleaning efficiency, reduces manual intervention, and lowers labor intensity. It also eliminates the need for manual work in dangerous environments such as rapid currents and inclement weather, effectively ensuring worker safety. Workers no longer need to approach the debris screen by boat, reducing the risk of accidental falls into the water or being swept away by currents. Traditional mechanical cleaning equipment struggles to remove small debris from the gaps in the debris screen, while this machine effectively removes stuck debris by inserting scraper teeth into the gaps, preventing long-term accumulation that could reduce the screen's water flow capacity. This reduces the operational risks of hydraulic structures and ensures the safe and stable operation of water conveyance systems and power generation equipment. Attached Figure Description

[0042] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0043] See Figure 1-4 As shown;

[0044] An automatic trash rack cleaning machine according to an embodiment of this utility model includes:

[0045] Suspension seat 1, floating on the water surface;

[0046] A conveyor support 11 is fixedly installed on the suspension seat 1. The conveyor support 11 is obliquely arranged on the suspension seat 1. A conveyor belt 12 is driven on the conveyor support 11.

[0047] Two cleaning brackets 13 are symmetrically arranged on the two side walls of the conveying bracket 11;

[0048] The scraping shaft 14 is rotatably mounted on two cleaning brackets 13;

[0049] The scraper motor 15 is fixedly mounted on one of the cleaning brackets 13 and is used to drive the scraper shaft 14 to rotate.

[0050] The scraper frame 16 is fastened to the scraper shaft 14. The scraper frame 16 is equipped with four scrapers, and each scraper is equipped with scraper teeth 17.

[0051] The processing unit 2 is installed on the suspension seat 1 and is used to receive and process the waste conveyed by the conveyor belt 12.

[0052] The rotating scraper 16 then passes through the gaps of the trash rack through the evenly arranged scraper teeth 17. Under the action of the rotating scraper teeth 17, the garbage intercepted in the gaps of the trash rack is hooked out and then flows to the conveyor belt 12 under the action of water flow. The garbage is transported by the conveyor belt 12.

[0053] By adopting the above technical solution, when the automatic trash rack cleaning machine is put into use, the suspension seat 1 floats on the water surface, providing a stable support platform for the entire equipment, allowing it to move flexibly on the water surface and approach the trash rack; then, the scraper motor 15 starts, driving the scraper shaft 14 to rotate, and the scraper frame 16, which is fastened to the scraper shaft 14, rotates accordingly; during the rotation, the scraper blades and scraper teeth 17 on the scraper frame 16 penetrate into the gaps of the trash rack, using the scraper teeth 17 to hook out the debris such as branches, plastic waste, and aquatic plants intercepted in the gaps; the hooked debris moves towards the conveyor belt 12 under the push of the water flow, and the conveyor belt 12 on the inclined conveyor support 11 continues to operate, transporting the debris to the processing mechanism 2 on the suspension seat 1, where the processing mechanism 2 performs further processing on the debris; compared with manual... Using hooks and nets to manually remove debris, this automatic trash rack cleaning machine, driven by a scraper motor 15 to rotate the scraper shaft 14 and scraper frame 16, can achieve continuous automatic operation, greatly improving cleaning efficiency, reducing manual intervention, and lowering labor intensity. It avoids manual operation in dangerous environments such as rapid water flow and severe weather, effectively ensuring the personal safety of workers. Workers do not need to approach the trash rack by boat, reducing the risk of accidental falling into the water or being swept away by the current. Traditional mechanical cleaning equipment is difficult to remove small debris from the gaps in the trash rack, but this cleaning machine uses scraper teeth 17 to insert into the gaps and hook out the debris, effectively cleaning the debris stuck in the gaps, preventing the long-term accumulation of debris from reducing the water passage capacity of the trash rack, reducing the operational risks of hydraulic structures, and ensuring the safe and stable operation of water conveyance systems and power generation equipment.

[0054] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, the processing mechanism 2 includes:

[0055] Mounting bracket 21 is fixedly installed on suspension seat 1;

[0056] The processing bucket 22 is fixedly installed on the mounting bracket 21 and is used to receive the waste discharged from the conveyor belt 12.

[0057] External bracket 23 is fixedly installed on the outer wall of the processing bucket 22;

[0058] Four rotary cutting components are installed in the processing hopper 22 to rotary cut the conveyed and falling waste;

[0059] In this embodiment, the conveyor belt 12 transports the hooked garbage upwards to the end, where it falls off. Since the processing hopper 22 is fixedly mounted on the suspension seat 1 via the mounting bracket 21, it can accurately receive the garbage discharged from the conveyor belt 12. Once the garbage falls into the processing hopper 22, four rotary cutting components within it begin to operate. These components, through their rotational motion, perform a rotary cutting operation on the garbage falling into the processing hopper 22. After processing by the rotary cutting components, the volume and shape of the garbage change, preparing it for further processing. The rotary cutting components can cut the falling garbage, reducing larger pieces into smaller fragments. This helps reduce the total volume of the garbage, saves storage space, facilitates subsequent transportation and processing, and lowers transportation costs and processing difficulty. The processing hopper 22 promptly receives the garbage discharged from the conveyor belt 12 and processes it using the rotary cutting components, preventing garbage accumulation within the hopper. This continuous processing method improves the overall efficiency of the cleaning system, making the cleaning process smoother and reducing equipment malfunctions and cleaning interruptions caused by garbage accumulation.

[0060] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, the rotary cutting assembly includes:

[0061] The rotary cutting motor 24 is fixedly mounted on the external bracket 23;

[0062] The rotary cutting shaft 25 is rotatably inserted into the processing bucket 22, and the rotary cutting shaft 25 is driven to rotate by the rotary cutting motor 24;

[0063] Multiple cutting blades 26 are evenly arranged on the rotary cutting shaft 25;

[0064] In this embodiment, after the conveyor belt 12 transports the waste to the top of the processing hopper 22 and discharges the waste, the rotary cutting motor 24, which is fixedly installed on the external bracket 23, starts to work. The external bracket 23 provides a stable installation position for the rotary cutting motor 24, ensuring that the rotary cutting motor 24 can operate normally. The rotary cutting motor 24 drives the rotary cutting shaft 25 to rotate. The rotary cutting shaft 25 is rotatably inserted into the processing hopper 22, and the processing hopper 22 provides support and limit for the rotary cutting shaft 25, enabling it to rotate stably. Multiple cutters 26 are evenly arranged on the rotary cutting shaft 25. As the rotary cutting shaft 25 rotates, the cutters 26 also rotate at high speed. When the waste falls into the processing hopper 22, the high-speed rotating cutters 26 cut and crush the waste, breaking down larger pieces of waste into smaller pieces. The waste is shredded into smaller pieces by multiple cutters 26 evenly arranged on the rotary cutting shaft 25, which can cut the waste falling into the processing hopper 22 from all directions. Whether it is branches, plastic waste or weeds, the cutters 26 can cut them into smaller pieces, thereby greatly reducing the volume of waste. This helps to store, transport and process the waste more efficiently and reduce processing costs. The waste intercepted by the trash rack is diverse, including some long strips or large pieces of debris. If it is not rotary cut, these debris may clog the equipment during subsequent transportation or processing, affecting the normal operation of the entire cleaning system. The rotary cutting component cuts the waste into small pieces, reducing the risk of equipment blockage, ensuring stable operation of the equipment, and reducing equipment failure and maintenance costs.

[0065] As a preferred embodiment of the above technical solution, such as Figure 3 As shown, the processing mechanism 2 also includes:

[0066] The transfer bucket 27 is connected to the bottom of the processing bucket 22;

[0067] The conveying pipe 28 is connected to the transfer bucket 27, and a lifting frame 29 is installed on the conveying pipe 28. The lifting frame 29 is fixedly connected to the external bracket 23.

[0068] A conveying assembly, mounted on conveying pipe 28, is used to convey shredded waste outwards;

[0069] In this embodiment, the shredded waste processed by the rotary cutting assembly falls to the bottom of the processing hopper 22. Since the transfer hopper 27 is connected to the bottom of the processing hopper 22, the shredded waste naturally collects in the transfer hopper 27. The conveying pipe 28 is connected to the transfer hopper 27, and the shredded waste collected in the transfer hopper 27 enters the conveying pipe 28. The lifting frame 29 on the conveying pipe 28 is fixedly connected to the external bracket 23, which is fixed to the outer wall of the processing hopper 22. This structure provides stable support for the conveying pipe 28, ensuring that the conveying pipe 28 maintains the correct position and angle for smooth waste transport. The conveying assembly on the conveying pipe 28 starts working, transporting the shredded waste that has entered the conveying pipe 28 to the designated location; the transfer bucket 27 connects the processing bucket 22 and the conveying pipe 28, forming a continuous waste processing and conveying channel; the waste processed by the rotary cutting assembly can smoothly enter the transfer bucket 27 from the processing bucket 22, and then be transported outward by the conveying assembly through the conveying pipe 28, realizing the automation and continuity of waste processing and improving the efficiency of the entire cleaning system; the conveying assembly can transport the shredded waste to the designated location, facilitating centralized waste processing and improving the efficiency and effectiveness of waste processing.

[0070] As a preferred embodiment of the above technical solution, such as Figures 3 to 4 As shown, the transmission component includes:

[0071] A conveying shaft 2a is rotatably installed in a conveying pipe 28, and a spiral blade 2b is spirally provided on the conveying shaft 2a;

[0072] A conveyor motor 2c is fixedly installed at the outer end of the conveyor pipe 28, and a drive wheel 2d is provided at the output end of the conveyor motor 2c.

[0073] Driven wheel 2e is fixedly installed on the outer end of conveyor shaft 2a, and driven wheel 2d is driven by belt;

[0074] In this embodiment, when the waste in the processing hopper 22 is processed by the rotary cutting assembly and enters the transfer hopper 27 and flows into the conveying pipe 28, the conveying motor 2c, which is fixedly installed at the outer end of the conveying pipe 28, starts to work; the drive wheel 2d set at the output end of the conveying motor 2c rotates accordingly, and transmits power to the driven wheel 2e, which is fixedly installed at the outer end of the conveying shaft 2a, through belt drive, thereby driving the conveying shaft 2a to rotate in the conveying pipe 28; a spiral blade 2b is spirally arranged on the conveying shaft 2a, and the spiral blade 2b also rotates with the rotation of the conveying shaft 2a; the shredded waste is conveyed... In pipe 28, driven by the spiral blade 2b, the material moves forward along the axial direction of the conveying pipe 28 to transport the waste. Under the continuous push of the spiral blade 2b, the shredded waste is finally transported to the outlet end of the conveying pipe 28 and discharged to the designated location. The spiral structure of the spiral blade 2b can continuously and stably push the waste forward, avoiding the accumulation and blockage of waste during the conveying process and improving the waste conveying efficiency. Compared with other conveying methods, spiral conveying can transport a large amount of shredded waste in a shorter time, ensuring the continuous operation of the cleaning system.

[0075] As a preferred embodiment of the above technical solution, such as Figure 1 As shown, the conveyor belt 12 is provided with drainage holes;

[0076] In this embodiment, after the scraper teeth 17 on the scraper frame 16 hook out the garbage intercepted in the gaps of the garbage rack, the garbage flows towards the conveyor belt 12 under the action of water flow. Since the conveyor belt 12 is set at an angle, during the process of transporting garbage, a large amount of water carried in the garbage will flow downward due to gravity and the inclination of the conveyor belt 12. At this time, the seepage holes provided on the conveyor belt 12 provide a drainage channel for the water. The water will seep out from the conveyor belt 12 through these seepage holes, while the garbage remains on the surface of the conveyor belt 12 and continues to be transported upward by the conveyor belt 12 to the processing hopper 22. Before entering the processing mechanism 2, most of the water in the garbage is discharged through the seepage holes on the conveyor belt 12. The water content of the garbage entering the processing hopper 22 is reduced, which reduces the water interference that the subsequent rotary cutting component needs to deal with when processing the garbage, reduces the load on equipment such as the rotary cutting motor 24, improves the working efficiency and service life of the rotary cutting component, and also reduces the burden on the subsequent conveying components and the entire garbage processing process.

[0077] As a preferred embodiment of the above technical solution, each scraper tooth 17 is threadedly inserted into the scraper frame 16;

[0078] In this embodiment, the threaded insertion method makes the installation and removal of the scraper tooth 17 simple and convenient, without the need for complicated tools and professional technical knowledge; the staff can quickly replace the scraper tooth 17 on site, reducing equipment downtime, improving equipment maintenance efficiency, and reducing maintenance costs; the threaded connection has good self-locking performance, which can ensure that the connection between the scraper tooth 17 and the scraper frame 16 is firm and reliable; during the cleaning process, the scraper tooth 17 needs to withstand a large external force, and the threaded insertion structure can effectively prevent the scraper tooth 17 from loosening or falling off, ensuring the normal progress of the cleaning work and improving the working stability and reliability of the equipment.

[0079] As a preferred embodiment of the above technical solution, a waterproof cover is provided on the outer end of the scraper motor 15;

[0080] In this embodiment, since the cleaning machine is in an aquatic environment with a large amount of water around it, and water may splash during operation, the waterproof cover fitted on the outside of the scraper motor 15 can act as a barrier, isolating the water outside the waterproof cover and preventing the water from directly contacting the internal structure of the scraper motor 15. This ensures that the scraper motor 15 operates in a dry and safe environment, reduces the risk of damage to the motor due to water corrosion, extends the service life of the scraper motor 15, and reduces equipment maintenance and replacement costs.

[0081] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
