Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, in particular to a sewage dredging equipment. BACKGROUND

[0002] Sewage dredging is to remove the sludge, sundries and pollutants deposited in the sewage pipeline, pond, river and other water bodies by artificial or mechanical means to restore the unobstructedness of the water body or pipeline and ensure normal operation and environmental safety. Its main purpose is to ensure the normal operation of the sewage treatment system, prevent environmental pollution, maintain urban infrastructure and improve the ecological environment.

[0003] In related technologies, a Korean patent with the authorization announcement number KR1020030018512A discloses a street entrance side ditch dredging device and method, which is composed of a driving device, a flexible cable and a flexible conveying belt. The flexible conveying belt is driven to rotate forward by the driving device, bends into the entrance of the drainage pipe, and the accumulated sundries such as silt in the drainage pipe are conveyed to the outside by the flexible conveying belt through the reverse rotation of the flexible conveying belt, so that the accumulated sundries in the drainage pipe can be removed, and the road or house can be prevented from being flooded by rainwater or sewage in the case of heavy rainfall.

[0004] However, the above-mentioned dredging device has many cleaning blind spots when the flexible conveying belt is dredged, the dredging effect is poor, and the drainage pipe needs to be cleaned frequently in actual work application. CONTENT OF THE INVENTION

[0005] In order to improve the cleaning effect of dredging the inside of the sewage, the present application provides a sewage dredging equipment.

[0006] The sewage dredging equipment provided by the present application adopts the following technical scheme:

[0007] A sewage dredging equipment, comprising a machine body, a hydraulic motor crawler chassis is arranged at the bottom of the machine body, the machine body moves through the hydraulic motor crawler chassis, a sundry absorbing device for absorbing sundries is arranged on the machine body, and the sundry absorbing device comprises:

[0008] A sundry absorbing pipe is arranged on the machine body, and a suction pump is arranged on the sundry absorbing pipe;

[0009] A discharge pipe is arranged on the machine body and communicates with the inside of the sundry absorbing pipe;

[0010] A crushing mechanism is arranged on the machine body, and the crushing mechanism is used for crushing the sundries at the sundry absorbing pipe port.

[0011] By adopting the above technical solution, after the machine body is placed in the sewage, the hydraulic motor track chassis starts to drive the machine body to move. While the machine body is moving, the crushing mechanism crushes the impurities deposited at the bottom of the sewage. Then, the suction pipe sucks in the crushed impurities and discharges them through the discharge pipe, thereby completing the cleaning of impurities. The machine body can move anywhere and clean without creating blind spots, which greatly improves the cleaning effect.

[0012] Optionally, the crushing mechanism includes:

[0013] A crushing frame, which is rotatably mounted on the machine body;

[0014] A first rotating assembly is mounted on the machine body and is used to control the rotation of the crushing frame;

[0015] A crushing roller is rotatably mounted on a crushing frame, and crushing spikes are evenly distributed on the crushing roller.

[0016] The second rotating assembly is disposed on the crushing frame and is used to drive the crushing roller to rotate.

[0017] By adopting the above technical solution, the first rotating component starts and drives the crushing frame to rotate. The rotation of the crushing frame causes the crushing roller to come into contact with the deposited impurities. Then, the second rotating component starts and drives the crushing roller to rotate. The rotation of the crushing roller crushes the impurities through the crushing spikes, thereby stirring up and breaking up the impurities adhering to the ground, which facilitates the adsorption work of the impurity suction pipe.

[0018] Optionally, the first rotating component includes:

[0019] The first rotating plate is mounted on the crushing frame and is rotatably connected to the machine body.

[0020] The first hydraulic cylinder is mounted on the machine body, and its piston rod is rotatably connected to the first rotating plate.

[0021] By adopting the above technical solution, the first hydraulic cylinder is started to drive the first rotating plate to rotate, and the rotation of the first rotating plate drives the crushing frame to rotate, thereby realizing the rotation of the crushing frame by controlling the first hydraulic cylinder.

[0022] Optionally, the second rotating component includes:

[0023] The second rotating shaft is rotatably mounted on the crushing frame, and the crushing roller is mounted on the second rotating shaft;

[0024] The second rotating motor is mounted on the crushing frame and its output shaft is connected to the second rotating shaft.

[0025] A torque sensor is mounted on the crushing frame and is used to detect the torque of the second rotating shaft.

[0026] The control unit is mounted on the crushing frame and is used to receive the torque signal from the torque sensor and control the second rotating motor to rotate in both directions.

[0027] By adopting the above technical solution, the second rotating motor starts and drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the crushing roller to rotate. The rotation of the crushing roller crushes impurities through the crushing spikes. At the same time as the second rotating shaft rotates, the torque sensor detects the torque of the second rotating shaft. When the torque sensor detects that the torque value exceeds the target value, it means that the crushing roller is stuck by large particles of impurities. Then the control unit controls the second rotating motor to reverse until the torque sensor detects that the torque value has returned to normal, thereby ensuring that the crushing roller can keep rotating and crushing.

[0028] Optionally, the suction pipe is a corrugated hose, and the end of the suction pipe away from the discharge pipe is connected to the crushing frame and communicates with the interior of the crushing frame.

[0029] By adopting the above technical solution, the suction pipe is set to be a suction pipe made of corrugated hose, so that the suction pipe can move with the rotation of the crushing frame, which makes it easy for the suction pipe to keep suctioning the side of the crushing roller at all times.

[0030] Optionally, the machine body is provided with a hydraulic supply unit, which includes hydraulic pipes and a hydraulic distributor. The hydraulic distributor is installed on the machine body and has an oil injection pipe. The oil injection pipe injects hydraulic oil into the hydraulic distributor. Several hydraulic pipes are provided, and the several hydraulic pipes are respectively connected to the hydraulic motor track chassis and the first hydraulic cylinder.

[0031] By adopting the above technical solution, a hydraulic supply unit is set on the machine body, and hydraulic oil is continuously injected into the hydraulic motor track chassis and the first hydraulic cylinder through hydraulic pipes and hydraulic distributors, thereby ensuring the normal working condition of the machine body.

[0032] Optionally, the crushing frame is equipped with a high-pressure nozzle, which sprays high-pressure water onto both sides of the crushing frame.

[0033] By adopting the above technical solution, high-pressure nozzles are installed on the crushing frame. The high-pressure water sprayed from the nozzles can impact the impurities located on both sides of the crushing roller, washing away the impurities adhering to the ground, making it easier to crush and absorb them. When facing some cleaning blind spots that the crushing roller cannot reach, the high-pressure nozzles can also directly rinse, greatly improving the cleaning effect of impurities.

[0034] Optionally, the machine body is equipped with an infrared camera, which captures real-time images of the environment in front of the crushing frame.

[0035] By adopting the above technical solution and installing an infrared camera on the machine body, the environment in front of the crushing frame can be photographed in real time through the infrared camera, which makes it easier for manual control of the machine to clean up the areas where impurities are accumulated, and greatly reduces the probability of blind spots in cleaning.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. The machine body is moved by starting the tracked chassis via a hydraulic motor. While the machine body is moving, the crushing mechanism crushes the impurities deposited at the bottom of the sewage. Then, the suction pipe sucks in the crushed impurities and discharges them through the discharge pipe, thus completing the cleaning of impurities. The machine body can move anywhere and clean without creating blind spots, which greatly improves the cleaning effect.

[0038] 2. By setting the suction pipe to be made of corrugated hose, the suction pipe can move with the rotation of the crushing frame, so that the suction pipe can always keep suctioning the side of the crushing roller;

[0039] 3. By installing an infrared camera on the machine body, the environment in front of the crushing frame can be photographed in real time, which makes it easier for manual control of the machine to clean up areas with accumulated impurities, greatly reducing the probability of blind spots in cleaning.

[0043] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0044] This application discloses a sewage dredging device.

[0045] Reference Figure 1 The sewage dredging equipment includes a body 1, with a hydraulic motor tracked chassis 11 fixedly mounted on the bottom of the body 1. The body 1 moves via the hydraulic motor tracked chassis 11. A suction device 2 for absorbing impurities is installed on the body 1.

[0046] Reference Figure 1 and Figure 2 The impurity suction device 2 includes an impurity suction pipe 21, an exhaust pipe 22, and a crushing mechanism 23. The impurity suction pipe 21 is fixedly installed on the upper surface of the machine body 1. An intake pump 24 is fixedly installed on the upper surface of the machine body 1. One end of the impurity suction pipe 21 is connected to the outer wall of the intake pump 24 and communicates with the interior of the intake pump 24. One end of the exhaust pipe 22 is fixedly installed on the top of the intake pump 24 and communicates with the interior of the intake pump 24. The other end of the exhaust pipe 22 extends out of the machine body 1.

[0047] Reference Figure 1 and Figure 2 The crushing mechanism 23 is mounted on the machine body 1 and is used to crush impurities located at the inlet of the suction pipe 21. The crushing mechanism 23 includes a crushing frame 31, a first rotating assembly 32, a crushing roller 33, and a second rotating assembly 34. The crushing frame 31 is rotatably mounted on the end of the machine body 1. The first rotating assembly 32 is mounted on the machine body 1 and is used to control the rotation of the crushing frame 31.

[0048] Reference Figure 1 and Figure 2 The first rotating assembly 32 includes a first rotating plate 41 and a first hydraulic cylinder 42. One end of the first rotating plate 41 is rotatably mounted on the outer wall of the machine body 1, and the other end of the first rotating plate 41 is fixedly connected to the side wall of the crushing frame 31 near the machine body 1. The first hydraulic cylinder 42 is fixedly mounted on the machine body 1 and is arranged horizontally. The piston rod of the first hydraulic cylinder 42 is rotatably connected to the first rotating plate 41. When the first hydraulic cylinder 42 is activated, it drives the first rotating plate 41 to rotate, and the rotation of the first rotating plate 41 drives the crushing frame 31 to rotate. Thus, the rotation of the crushing frame 31 is achieved by controlling the first hydraulic cylinder 42.

[0049] Reference Figure 2The crushing roller 33 is rotatably mounted on the inner wall of the crushing frame 31, and crushing spikes are evenly distributed on the outer wall of the crushing roller 33. A second rotating assembly 34 is disposed on the crushing frame 31 and is used to drive the crushing roller 33 to rotate. The second rotating assembly 34 includes a second rotating shaft 43, a second rotating motor 44, a torque sensor, and a control unit 45. The second rotating shaft 43 is rotatably mounted on the inner wall of the crushing frame 31, and the crushing roller 33 is fixedly mounted on the second rotating shaft 43. The torque sensor is fixedly mounted on both ends of the second rotating shaft 43 and is used to detect the torque of the second rotating shaft 43. The control unit 45 is fixedly mounted on the outer wall of the crushing frame 31. The control unit 45 is used to receive the torque signal from the torque sensor and control the second rotating motor 44 to rotate in both directions.

[0050] Reference Figure 2 The second rotating motor 44 starts and drives the second rotating shaft 43 to rotate. The rotation of the second rotating shaft 43 drives the crushing roller 33 to rotate. The rotation of the crushing roller 33 crushes impurities through the crushing spikes. At the same time as the second rotating shaft 43 rotates, the torque sensor detects the torque of the second rotating shaft 43. When the torque sensor detects that the torque value exceeds the target value, it means that the crushing roller 33 is stuck by large particles of impurities. Then the control unit 45 controls the second rotating motor 44 to reverse until the torque sensor detects that the torque value has returned to normal, thereby ensuring that the crushing roller 33 can keep rotating and crushing.

[0051] Reference Figure 2 The suction pipe 21 is made of corrugated flexible hose. The end of the suction pipe 21 away from the discharge pipe 22 is connected to the crushing frame 31 and communicates with the inside of the crushing frame 31. Under the action of the suction pump 24, the suction pipe 21 absorbs the impurities after crushing by the crushing roller 33.

[0052] Reference Figure 1 and Figure 2 The machine body 1 is equipped with a hydraulic supply unit 5, which includes hydraulic pipes 51 and a hydraulic distributor 52. The hydraulic distributor 52 is fixedly mounted on the upper surface of the machine body 1.

Several hydraulic pipes 51 are provided, and the several hydraulic pipes 51 are respectively connected to the hydraulic motor track chassis 11 and the first hydraulic cylinder 42.

[0053] Reference Figure 1 and Figure 2High-pressure nozzles 12 are fixedly installed on the outer walls of both ends of the crushing frame 31, spraying high-pressure water onto both sides of the crushing frame 31. The high-pressure water sprayed from the nozzles 12 impacts impurities located on both sides of the crushing roller 33, washing away impurities adhering to the ground for easier crushing and absorption. When facing cleaning blind spots that the crushing roller 33 cannot reach, the high-pressure nozzles 12 can also directly rinse, greatly improving the cleaning effect of impurities.

[0054] Reference Figure 1 and Figure 2 An infrared camera 13 is fixedly installed on the upper surface of the machine body 1, which captures real-time images of the environment in front of the crushing frame 31. This facilitates manual control of the machine body 1 to clean areas with accumulated impurities, greatly reducing the probability of blind spots in the cleaning process.

[0055] The working principle of this application embodiment is as follows:

[0056] After the machine body 1 is placed into the sewage, the hydraulic motor track chassis 11 starts and drives the machine body 1 to move. While the machine body 1 moves, the crushing roller 33 rotates to crush the impurities deposited at the bottom of the sewage. Then, the suction pipe 21 sucks in the crushed impurities and discharges them through the discharge pipe 22, thus completing the cleaning of impurities. The machine body 1 can move anywhere and clean without creating blind spots, which greatly improves the cleaning effect.
