Description

Technical Field

[0001] The utility model relates to the technical field of cutter suction vessels, in particular to a cutter suction vessel multi-pump series mud blowing structure. Background Art

[0002] A dredger is a professional engineering vessel, mainly used for cleaning waterways, ports, rivers or canals. It usually has a special forced water intake system, which can suck silt, sand and other bottom mud into its own cabin, and then separate the water and slurry after squeezing and cutting through a special auger system before discharging it.

[0003] The above device does not have a structure for blowing mud and clearing blockage in the dredger suction pipe when in use, so that the existing dredger suction pipe is very easy to adhere to the pipe wall after entering the dredger suction pipe due to the strong adhesion of riverbed silt, thereby causing accumulation and blockage and making it impossible to continue to use. Based on the shortcomings of the existing technology, the utility model designs a dredger suction pipe with multiple pumps in series for blowing mud. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a cutter suction vessel multi-pump series mud blowing structure, which has the advantages of mud blowing and clearing blockage in the mud suction pipe of the cutter suction vessel.

[0006] The mud discharge mechanism includes a mud discharge groove, a fixed sliding frame, a limit plate, a sealing slide plate, a connecting plate, a telescopic rod and an oil cylinder. The mud discharge groove is opened at the bottom of the mud suction pipe, the fixed sliding frame is fixedly connected to the outer surface of the mud suction pipe, the limit plate is fixedly connected to the outer surface of the mud suction pipe, the sealing slide plate is slidably connected to the inside of the fixed sliding frame, the connecting plate is fixedly connected to the outside of the sealing slide plate, the telescopic rod is fixedly connected to one side of the connecting plate, and the oil cylinder is arranged at one end of the telescopic rod away from the connecting plate.

[0007] As a preferred technical solution of the utility model, an air pump is fixedly connected to one side of the motor, a compressed gas cylinder is fixedly connected to one side of the air pump, and an air pipe is fixedly connected to the compressed gas cylinder.

[0008] As an optimal technical solution of the utility model, the front end of the suction arm is fixedly connected to a transmission head, the front end of the transmission head is rotatably connected to a twisting head, the rear end of the suction arm is fixedly connected to a connecting end head, and a mud suction port is opened at the front end of the transmission head.

[0009] As a preferred technical solution of the utility model, the inner cavity of the mud suction port is communicated with the mud suction pipe.

[0010] As a preferred technical solution of the utility model, the other end of the air pipe is fixedly connected to the mud suction pipe.

[0011] As a preferred technical solution of the utility model, an electric-controlled valve is provided between the compressed gas cylinder and the gas pipe.

[0012] As a preferred technical solution of the utility model, the sealing slide plate is slidably connected to the outside of the mud discharge groove, and the telescopic rod is slidably inserted into the inside of the limiting plate.

[0013] As a preferred technical solution of the utility model, the oil cylinder is fixedly connected to the outer surface of the mud suction pipe.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The multi-pump series mud blowing structure of a dredger suction ship uses an oil cylinder to control the telescopic rod to be retracted into the interior. The movable telescopic rod uses a connecting plate to pull the sealing slide plate to slide inside the fixed slide frame under the limit of the limit plate, so that the sealing slide plate moves out from under the mud discharge groove. At this time, the motor uses an air pump to pressurize and inflate the compressed gas cylinder. After the pressure in the compressed gas cylinder reaches a certain value, the electric control valve between the compressed gas cylinder and the air pipe is opened, so that the high-pressure gas in the compressed gas cylinder enters the mud suction pipe through the air pipe, thereby blowing the mud blocked in the mud suction pipe in the opposite direction and discharging it from the mud discharge groove and the mud suction port. The device is convenient for blowing out the mud blocked in the mud suction pipe. BRIEF DESCRIPTION OF THE DRAWINGS
