Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a dredger fitting for ensuring normal transportation of a mud pipe based on centrifugal rotation includes a mud pipe body 1 and a reamer body 9, wherein a fixed suction rod 2 is fixedly installed at the lower end of the mud pipe body 1 to penetrate through and extend to the lower part of the reamer body 9.

As shown in fig. 4, the lower end of the mud pipe body 1 is movably mounted with the reamer body 9 through a sealing ring 902, the mud pipe body 1 has two sections, the mud pipe body 1 located at the lower end of the reamer body 9 is fixedly mounted with the sealing ring 902, and the lower end of the mud pipe body 1 at the upper end is movably mounted with the sealing ring 902, therefore, when the reamer body 9 rotates, the mud pipe body 1 at the lower end can be driven to rotate, the mud pipe body 1 at the upper end of the sealing ring 902 does not rotate, the fixed suction rods 2 are located at two sides of the mud pipe body 1, the fixed suction rods 2 are in an inclined state, the fixed suction rods 2 above incline upwards, the fixed suction rods 2 below incline downwards, and mainly for omnibearing mud suction, and the suction balls 3 are fixedly mounted at one end of the fixed suction rods 2 far away from the.

Through the cooperation of fixed suction rod 2 and suction ball 3, convenient effectual thin silt is inhaled, and big cubic rubble etc. is smashed by reamer body 9 again, has avoided reamer body 9 when excavating some rubbles, when soil property such as sand cobble, because contain the stone of big particle diameter piece in the soil body, mud conveying pipe body 1 smashes the pump courage with the stone at inspiratory in-process, and the stone breaks the pump courage, increases wearing and tearing, has reduced the pump efficiency, makes dredge pump life subtract weak point.

Defeated mud pipe body 1's low side fixed mounting has stirring frame 4, the inside upper end fixed mounting of stirring frame 4 has connecting rod 5, the lower extreme fixed mounting of connecting rod 5 has hinge bar 6, through connecting rod 5, hinge bar 6 and counter weight ball 7's cooperation is used, can make things convenient for effectual alga to smash with earth mixture, avoided blocking up the inside at defeated mud pipe body 1 with the earth conglobation or caking after the alga mixes, cause unable maximum efficiency's mud transportation to the another side after will smashing, still avoided defeated mud pipe body 1 to block up the back simultaneously, need the staff to descend the sewer or consume great manpower and material resources and transport it to the onshore mediation, work step has been simplified.

The two symmetrical hinged rods 6 are elastically connected through a telescopic spring 8, and a counterweight ball 7 is hinged between the two symmetrical hinged rods 6.

The both sides of reamer body 9 upper end articulate through articulated post 901 respectively have cutter 10, when rotating through reamer body 9, can drive the flow of rivers, and rivers can be beaten on breakwater 13 when flowing, drive the rotation of changeing sword 12, can effectually give the comminution with some big stones, avoid big stone to get into in the reamer body 9, fixed suction rod 2 can't rub it with inhaling ball 3.

The cutter 10 is formed by assembling an upper cutter 101 and a lower cutter 102, the upper cutter 101 and the lower cutter 102 are arranged in a staggered manner from front to back, crushing cutters 11 are respectively fixedly installed on two sides of the lower end of the reamer body 9, a rotary cutter 12 is movably installed on the reamer body 9, and a water blocking sheet 13 is fixedly installed on the outer surface of the rotary cutter 12.

When in use, the utility model is used,

the first step is as follows: the manual operation dredger starts the reamer body 9 to rotate, and after the reamer body 9 rotates, the crushing cutter 11 rotates along with the reamer body to dig out sediment and small stones on the seabed.

The second step is that: because the cutter 10 is composed of the upper cutter and the lower cutter 102, when algae live on sea creatures such as kelp and the like, the algae are wound on the cutter 10, the cutter 10 is arranged obliquely downwards, according to Newton's law of universal gravitation, the algae inevitably fall down due to gravity to drive the upper cutter 101 to rotate downwards, and because the upper cutter 101 and the lower cutter 102 are arranged in a staggered manner from front to back, some of the algae are inevitably cut off, so that the condition that the algae are not excessively wound on the reamer body 9 is ensured, and the algae are crushed.

The third step: when the reamer body 9 rotates, the flowing of water flow around can be driven, the flow velocity of the water flow impacts the water retaining sheet 13, and in addition, when the reamer body 9 rotates, the inertia generated by the rotary cutter 12 can also rotate, so that a plurality of large stones are cut for a small time, and the normal transportation of the mud conveying pipe body 1 is ensured.

The fourth step: because the lower end of the mud conveying pipe body 1 rotates together with the reamer body 9, when the lower end of the mud conveying pipe body 1 rotates, the counterweight ball 7 generates centrifugal force due to the high-speed driving of the counterweight ball 7, the angle of the two symmetrical hinge rods 6 is enlarged and close to each other, and the crushing area is increased when the hinge rods 6 and the counterweight ball 7 rotate.

The fourth step: the fixed suction rod 2 and the suction ball 3 can suck away the crushed mud stone due to the suction force of the mud conveying pipe 1.
