Description
Technical field
The utility model belongs to dredging plant technical field more particularly to a kind of suction of quick change grid mouth spacing size
Mud mouth structure.
Background technology
In the course of work of cutter suction dredger, mud suction mouth is easy by blockings such as stones to be that emphasis in work progress is asked
One of topic, i.e., during strand is inhaled and dredged, the stone card resistance of bulk leads to shut down being handled, indulges in mud suction mouth
When delaying work, construction cost is enabled to be promoted.
The conventional method for solving above-mentioned blockage problem is that grid is arranged in the mud suction mouth of original cutter suction dredger, and grid is all
Be made using steel plate, generally comprise multiple vertical bars, between adjacent vertical bar welding multiple horizontal stripes are set, horizontal stripe and
Entire mud suction mouth is divided into multiple osculums by vertical bar, is equivalent in mud suction mouth and is provided with stone mesh screen, and grain size is more than sieve pore
Stone will be blocked in the outside of grid, prevents the stone of bulk from entering slush pump by mud suction mouth, avoids to blade wheel of slurry pump
It damages or causes pipeline that problem is seriously worn.
However, after setting metallic plate grid, when construction area contains more stony, clay, netted sundries, still can send out
Raw the case where blocking suction inlet, i.e., smaller stone blocks the osculum of each differentiation simultaneously, clears up mud suction mouth very in such cases
Trouble needs to stop work and be cleared up, affects ship construction.In addition, being directed to different construction areas, can be known by sampling
The typical particle diameter size of stone in construction area carries out type selection to grid for stone particle size and would be even more beneficial to protecting
Blocking accident is further decreased on the basis of card ship construction efficiency.Existing fixed mud suction mouth cell structure can not meet
Above-mentioned requirements.
Utility model content
The utility model for solve technical problem present in known technology provide it is a kind of it is simple in structure, convenient for building,
Dismount mud suction mouth structure convenient, that quick-adjustsing quick change grid mouth spacing size can be carried out to spacing.
The utility model is adopted the technical scheme that solve technical problem present in known technology：One kind quickly changes
The mud suction mouth structure for becoming grid mouth spacing size includes the strand suction bridge that front end is equipped with necking, and bearing is equipped in the front end of necking
Seat is equipped with that rear end is connected to driving mechanism, front is located at mangler shaft in bearing block twisting to inhale in bridge, reamer is mounted on reamer
The front end of axis；Further include spoil disposal pipeline, spoil disposal pipeline is fixedly mounted on the lower section for twisting and inhaling bridge, and the mud suction mouth of front end extends to
Middle part below necking；Multiple grid vertical bars are equipped between the upper lip and lower lip of mud suction mouth, each grid vertical bar is mutually equal
Row and lateral spaced set；On each grid vertical bar, it is equipped with the connecting holes of multiple lateral direction penetratings along its length, each
Each connecting hole spaced set of grid vertical bar itself, each connecting hole horizontal alignment of two neighboring grid vertical bar；Adjacent two
Multiple studs are installed, the both ends of each stud are located at the connecting hole of one group of horizontal alignment between a grid vertical bar
It is interior.
The advantages of the utility model and good effect are：The utility model provides a kind of the fast of structure design advantages of simple
Speed changes the mud suction mouth structure of grid mouth spacing size, with the hard grid of the existing welding setting steel plate material at mud suction mouth
Mode is compared, by the way that multiple grid vertical bars arranged side by side are arranged between the upper lip and lower lip of mud suction mouth simultaneously in the technical program
Connecting hole is set on grid vertical bar, is used as grid horizontal stripe by wearing fixed stud in the connecting hole of horizontal alignment,
Grid vertical bar together constitutes anti-stone grid with grid horizontal stripe, effectively prevents the stone that grain size transfinites and enters slush pump and pipe
Line prevents impeller failure and pipeline blocking accident.Compared with existing non-removable hard grid, as the double of grid horizontal stripe
Hook bolt quite convenient for dismounting, also quite convenient for adjusted temporarily according to field working conditions two neighboring stud (grid horizontal stripe) it
Between distance, also just easily complete the size of grid mouth spacing.Meanwhile when stone blocking accident occurs, it can pass through
Above-mentioned stud (grid horizontal stripe) is dismantled to assist carrying out the removal of stone, therefore handles blocking accident and is easier, more saves
Time.
Preferably：Each grid vertical bar is steel plate material, the upper lip of upper end and mud suction mouth is welded and fixed, lower end with inhale mud
The lower lip of mouth is welded and fixed.
Preferably：The thickness of grid vertical bar is 3cm to 5cm, width is 5cm to 8cm, between two neighboring grid vertical bar
Lateral distance is 10cm to 15cm；The distance between two neighboring connecting hole is 4cm to 8cm on each grid vertical bar.
Preferably：The outer diameter of the middle part body of rod of stud is 15mm to 25mm.
