Description

Technical Field

[0001] The present invention relates to the technical field of dredging equipment, and particularly relates to a suspended dredging robot. Background Art

[0002] Due to perennial non-point source pollution in rivers and lakes, and the misconnection, mixed connection, and rainwater overflow of rainwater pipes into the river during rainy days, sludge accumulates in rivers and lakes. Drainage engineering dredging needs to be carried out every two or three years. With the development of technology, dredging robots are increasingly widely used. When traditional dredging robots carry out dredging, the machine body needs to be placed into lakes and rivers. The robot moves forward in the sludge through tracks. Since the sludge is soft and the terrain inside lakes and rivers is relatively complex, the dredging robot may tip over during the forward movement, affecting dredging, and it is rather troublesome to readjust the robot; there are generally large stones in the sludge in rivers and lakes. When the stones enter the conveying pipe, it is easy to cause the conveying pipe to be blocked. If a filter screen is provided at one end of the conveying pipe, the stones will also block the filter screen, affecting the sludge cleaning efficiency. Summary of the Invention

[0015] Beneficial effects

[0049] Specific usage method and function of this embodiment: Since a spiral propeller is provided at the bottom of the bottom plate 101, the movement of this device on the water surface can be controlled. When dredging, the staff can rotate the fastening screw 105. The fastening screw 105 rotates and releases the limit on the support rod 301. The staff can control the support rod 301 and the sludge screening mechanism 4 at the bottom to slide downward. The top of the telescopic slide rod 304 slides into the internal connection fixing ring 303 and contacts the internal spring. The spring at the top of the telescopic slide rod 304 can elastically push the sludge screening mechanism 4 into contact with the sludge in the river. The dredging reamer 4053 at the bottom of the sludge screening mechanism 4 contacts the sludge. The bottom of the motor box 4052 drives two groups of dredging reamers 4053 to rotate through gears. The dredging reamers 4053 push the sludge at the bottom upward. At this time, the sludge pump 201 is started. The suction force inside the sludge inlet pipe 4042 and the baffle B 4043 controls the sludge to enter the sludge inlet pipe 4042. The sludge enters the inner part of the outer box A 4012 from the sludge inlet pipe 4042, and then enters the sludge pump 201 through the sieve plate 4013 and the sludge collection pipe 202. During the sludge transmission process, the sieve plate 4013 can filter out larger stones in the sludge. After the sieve plate 4013 filters for a period of time, the electric telescopic rod A 4014 is started. One end of the electric telescopic rod A 4014 pushes the slider 4015 and the baffle A 4016 to slide simultaneously. When the slider 4015 slides into the groove of the outer box A 4012, the left baffle A 4016 slides to one side of the sieve plate 4013. At this time, the sludge passes through the middle of the other two baffles A 4016. The baffle A 4016 pushes the filtered gravel into the placement net 4017. The electric telescopic rod A 4014 retracts, slides the slider 4015 back, and pushes the slider 4015 back to its original position to complete the cleaning of the gravel;The silt enters the inside of the dewatering tank 601 through the silt pumping machine 201 and the silt discharge pipe 203. At this time, one group of dewatering tanks 601 is already filled with a mixture of silt and water. Under the influence of the flow control plate 605, the silt does not enter the other group of dewatering tanks 601. The motor inside the support box 501 starts, and the motor controls the rotation of the control screw rod 502 through bevel gears. The control screw rod 502 slides to one side under the push of the thread. The flow control plate 605 inside the dewatering tank 601 filled with the mixture of silt and water squeezes the silt and water. During the sliding process of the flow control plate 605, one end of the silt discharge pipe 203 will be blocked. At the same time, the filtered water will flow out from the filter screen at one end of the dewatering tank 601, and the silt remains and is compressed. The flow control plate 605 inside the other group of dewatering tanks 601 slides in the same direction, and the flow control plate 605 releases the blockage of the other end of the silt discharge pipe 203, and the silt will enter the dewatering tank 601 and automatically fill the dewatering tank 601. After a period of squeezing and inflowing, the control screw rod 502 rotates in the reverse direction, and the side filled with the silt mixed water starts to be squeezed. At this time, the electric telescopic rod B603 inside the electric telescopic rod B603 inside the dewatering tank 601 where the silt squeezing is completed starts, and the mud pushing plate 602 is pushed out of the dewatering tank 601, and the silt squeezed in the middle of the mud pushing plate 602 is sent to the silt placement box 103, completing the drainage and squeezing of the silt, as well as the transportation, cyclically squeezing and discharging the silt to reduce the weight of the silt.;

[0050] The above description is only an exemplary embodiment of the present invention and is not used to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
