Abstract

The utility model relates to an emulating gas suspension type injecting rake which belongs to the technical field of construction machinery. The utility model is composed of a rake frame, a supporting arm, a wheel, a towing bracket, a water spray pipe, an air exhaust pipe and a lifting steel cable, wherein the rake frame is connected with the wheel through the supporting arm; the water spray pipe and the air exhaust pipe are installed on the rake frame; an injecting nozzle which is downward is arranged on the pipe wall of the water spray pipe; an air nozzle which is upward is arranged on the pipe wall of the air exhaust pipe; the towing bracket and the lifting steel cable are arranged on the rake frame. When the utility model is used, high pressure water is ejected out through the injecting nozzle to stir floating mud and sludge and enable the floating mud and the sludge to suspend to form the density current; compressed air is transmitted into the air exhaust pipe through an air pump and then ejected out through the air nozzle, and the suspending mud is enabled to form air suspension type three-phase flow and is taken away from the dredging field by the natural water flow or the falling tide water flow.

Description

Imitative type gas suspension injecting rake

Technical field:

The utility model belongs to the construction machinery technical field, is a kind ofly can implement the equipment that the disturbance formula is desilted and dredged in coastal fleet of silt coast and fully-loaded stream river.

Background technology:

Seawater starts sailing against the current that a large amount of silts suspend and quilt is held under the arm because flood tide to be positioned at the coastal fleet of silt coast, constantly fall to becoming silted up on the way and be deposited in the riverbed, and the unable silt sand that will fall of ebb current restarts, be with it to return the sea, make silt lose the turnover balance, form river channel sedimentation, existing spoil disposal method for determining sand is to adopt mud-sucking device that the silt sucking-off of piling up in the riverbed is drained, but the method construction speed is slow, the construction costs height.

Summary of the invention:

The technical problems to be solved in the utility model provides a kind of imitative type gas suspension injecting rake that can remove place, coastal river mouth riverbed sludge simple and effectively.

The scheme of the utility model technical solution problem is to adopt rake frame, support arm, wheel, bracket, sparge pipe, air comb and hoisting wirerope to constitute, wherein harrowing frame is connected with wheel by support arm, sparge pipe, air comb are contained on the rake frame, direction jet nozzle is down arranged on the tube wall of sparge pipe, the air nozzle that is directed upwardly is arranged on the tube wall of air comb, on the rake frame bracket and hoisting wirerope are housed.During use, bracket is connected on the dredger hull, sparge pipe, air comb connect water pump and the air pump in the hull respectively, hoisting wirerope connects on the hull, determine the height of rake tool, bracket drags the rake tool with hull and moves ahead, water pump is thrown water under high pressure into sparge pipe, by the jet nozzle ejection, mud scum and mud are carried out disturbance, the formation density current makes it to suspend, air pump is input into the air comb with compressed air, by air nozzle ejection, make mud in suspension form gas suspension formula three-phase stream, then by natural flows or ebb current band from desilting site.

In order to adjust the liftoff spacing of jet nozzle, more effectively implement mud scum and mud are carried out disturbance, two-way adjustment screw rod is housed at rake on the frame, by adjusting the angle that two-way adjustment screw rod changes arm room, thus the liftoff spacing of conversion jet nozzle.

The utility model utilizes natural flows or ebb current, implements the mode of desilting and dredging of artificial perturbation's formula, has solved the new alluvial problem in coastal fleet of silt coast and the high concentration of sediment river course effectively, and desilting speed is fast, and reliable working performance is simple in structure.
