[0002] A dredging robot is a robot that can autonomously clean up silt and weeds in waterways such as rivers, reservoirs, and ports. By using dredging robots, the environmental impact of manual operations can be effectively reduced, and efficiency and safety can be improved.

[0003] The specific structure of the aforementioned dredging robot can be referenced from the dredging robot with patent number 202410117048.4; the dredging robot with patent number CN202011485004.5; and the dredging robot with patent number CN202211400072.6.

[0004] In summary, based on the publicly available technical information, existing dredging robots have structural drawbacks during operation, mainly in the following aspects: 1. The drive devices are mostly electrically driven, which cannot guarantee effective waterproofing when operating underwater, making them prone to electrical leakage accidents; 2. The dredging end mostly uses negative pressure suction, but in harsh underwater environments, it is easy to cause sludge pump blockage, leading to equipment failure and inability to operate normally. Some equipment is equipped with a crushing structure, but when encountering metal or stone impurities, the crushing equipment is easily damaged; 3. Under harsh underwater operating environments in some cases, dredging vehicles often suffer side collision damage when moving, which can easily lead to damage to the body or tracks; 4. Existing dredging vehicles require a power supply device to operate, causing inconvenience to the users.

[0005] In view of the shortcomings of existing technologies, the urgent technical problem to be solved by technical personnel in this industry is: how to design a dredging robot based on existing technologies, with the aim of using a non-electric drive method to selectively filter and remove liquid impurities in the dredging area and avoid clogging of the negative pressure pump.

[0028] As shown in the figure, this utility model achieves the combined use of the frame and the dredging machine by setting up a combination kit. Furthermore, by improving the structure of the dredging machine, it effectively avoids problems such as blockage, leakage, and water leakage during operation, thereby improving the stability of the equipment operation.

[0029] Example 1:

[0030] As shown in the attached figure, a self-propelled dredging robot includes a frame 1 and a dredging machine 2.

[0031] The frame 1 is equipped with a hydraulic and electrical control area 13, a winding area 14, and a storage area 16. A base plate 15 is provided on the bottom surface of the storage area 16, and a positioning stop 161 for positioning is also provided inside. The hydraulic and electrical control area 13 is used to house a hydraulic pump station and an electrical control cabinet. Since the hydraulic pump station and electrical control cabinet are common equipment in the mechanical field, this technical solution only guides those skilled in the art to install the above equipment inside the frame 1; the specific installation method is not described in detail. Controlling the oil control circuit through the electrical control cabinet is a common technology in the mechanical field. As technicians in the field of mechanical automatic control, they can fully implement the wiring connection under the guidance of this manual, and details are not elaborated here.

[0032] The key structural improvements are as follows:

[0033] A support frame 17 is provided within the winding area 14 to fix the storage wheel 18. The storage wheel 18 is wound with a liquid supply pipe and a power supply line. In this embodiment, a 50-meter-long liquid supply pipe and power supply line are used to wire the hydraulic pump station and electrical control cabinet to the dredging machine 2. The top of the frame 1 has multiple lifting holes 11 for overall hoisting of the equipment, and the bottom of the frame 1 has a base 12 for ground support. The frame 1 serves to provide energy supply and a platform for ground personnel control, and also for the overall storage of the dredging machine 2. Users do not need to equip themselves with additional specialized equipment; modular integration results in higher efficiency and more stable operation.

[0034] The dredging machine 2 includes a frame 20, such as Figure 8 As shown, the bottom left and right sides of the frame 20 are provided with side support wheels 205 and end support wheels 203, as well as a travel hydraulic motor 204. The side support wheels 205, end support wheels 203, and travel hydraulic motor 204 together support the track 207. Furthermore, the end support wheels 203 are fixed to the telescopic frame 202, which is fixed inside the longitudinal frame 201. The longitudinal frame 201 is provided with a telescopic drive device that can drive the end support wheels 203 to tension the track 207. The telescopic drive device can be a hydraulic cylinder installed inside the longitudinal frame 201, or it can be a manual sleeve telescopic adjustment structure. After adjustment, the relative fixation between the telescopic frame 202 and the longitudinal frame 201 is achieved by tightening the locking nut.

[0035] A control compartment 21 is located at the top of the frame 20. The control compartment 21 has a waterproof structure and contains a hydraulic control valve. Two rear-side lifting holes 210 are provided on the control compartment 21 for lifting points. A hinge frame 22 is located on the front side of the control compartment 21. The hinge frame 22 has a front-side lifting hole 220, a hydraulic cylinder hinge hole 221, and a hinge frame fixing hole 222. The front-side lifting hole 220 and the rear-side lifting hole 210 work together to achieve the overall lifting of the dredging machine 2, allowing the self-propelled dredging robot to be lifted from the ground to locations such as rivers and reservoirs. The hydraulic cylinder hinge hole 221 and the hinge frame fixing hole 222 work together to hinge and fix the drive cylinder 4 and the entire lifting and cleaning module 5. The drive cylinder 4 is fixed between the lifting and cleaning module 5 and the hinge frame 22. Driven by the drive cylinder 4, the entire lifting and cleaning module 5 can be vertically lifted and swung.

[0036] The lifting and cleaning module 5 is equipped with a collection chamber 50, which contains a collection auger 55. A motor fixing plate 52 is installed on the top of the outer side of the collection chamber 50, which fixes the collection drive motor 53. The collection drive motor 53 drives the collection auger 55 to rotate through the drive belt and pulley inside the drive chamber 54. A protective cover 51 is installed on the front side of the collection chamber 50. The protective cover 51 has a perforated plate structure, which can perform initial filtration of liquid impurities entering the collection chamber 50. The rear side of the collection chamber 50 is connected to the collection chamber 6. A drain pump 7 is installed on the top surface of the collection chamber 6 through a water pump mounting hole 62. The drain pump 7 is equipped with a hydraulically powered drain motor 71 and an external drain interface 72, which can be directly connected to an external drainage pipeline.

[0037] This invention features a two-section design for the collecting auger 55, with two symmetrically arranged spiral blades 55 on the left and right sides. The two spiral blades 55 rotate in opposite directions, both guiding material from the left or right side towards the central area. The collecting auger 55 is positioned at the rear of the collecting auger 55, forming a collection chamber 6. Furthermore, several secondary sieve holes 61 are provided at the junction of the collection chamber 6 and the collection chamber 50. These secondary sieve holes 61 allow for secondary screening of impurities entering the collection chamber 6, effectively preventing larger particles from entering the drainage pump 7 and causing equipment malfunction.

[0038] On the left and right sides of the frame 1, protective plates 206 are provided on the outside of the track 207. The protective plates 206 provide side protection for the track 207, side support wheels 205, end support wheels 203, and travel hydraulic motor 204.

[0039] Because the hydraulic power and control circuit of the dredging machine 2 in this utility model are controlled through the hydraulic control area 13 on the ground during operation, the dredging machine 2 must be connected to the hydraulic control area 13 through oil pipes and control lines. The control compartment 21 is provided with a wiring through hole 211, a hydraulic pipe hole I 212, and a hydraulic pipe hole II 213. The hydraulic pipe hole II 213 is directly or indirectly connected to the control collection drive motor 53 and the drainage motor 71. The wiring through hole 211 and the hydraulic pipe hole I 212 are connected to the hydraulic control area 13 on the ground. In order to avoid the hydraulic pipe from bending and leaking when the dredging machine 2 turns or reverses, a support bracket 31 is provided at the tail end of the control compartment 21. The support bracket 31 is connected to the wire frame 3 through a turntable 32. The wire frame 3 is used to guide the external oil pipes and control lines to prevent the hydraulic pipes and lines from bending.

[0040] In summary, through the above structural design, this utility model integrates the frame 1 with the dredging machine 2 to provide auxiliary storage and energy supply for the dredging machine 2, eliminating the need for external power supply devices. Both the lifting cleaning module 5 and the collection bin 6 are equipped with filtering devices, effectively blocking large particles of impurities and preventing internal blockages in the dredging machine. The lifting, walking, and negative pressure suction drive devices of this utility model all utilize hydraulic motors, effectively improving power stability and eliminating the need to consider waterproofing under fuel or electric power. This utility model also features a track protection structure on the side of the machine body to prevent track damage during operation.
