Description

Drag suction dredger half T-type rake teeth with ribbing

Technical field

The utility model belongs to dredging work equipment technical field, more particularly to a kind of drag suction dredger with half T Type rake teeth with ribbing.

Background technique

Trailing suction hopper dredger is large and medium-sized from boat, hopper dredger, and drag suction dredger is one of suction type.Construction The devices such as Shi Liyong drag head, high-pressure flush, rake teeth are broken ground, are disturbed, and keep the dredging soil body loose, sufficiently mixed with surrounding water It closes, forms mud；Mud is packed into the spoil hopper of dredger by the swabbing action generated using dredge pump, resail after cabin is full to Deep water mud dumping area opens mud door dump or hydraulic reclamation to land cofferdam.Rake teeth has a significant impact to construction effect tool in work progress, The harder common rake teeth of soil property is difficult to excavate, especially silt soil, practical warehouse entry concentration is in similar project under construction 10%, construction efficiency is low.

The rake teeth used in previous construction is divided into chisel type tooth, conical tooth and plough type tooth.Chisel type tooth tooth tip is flat, construction Process embedded depth is limited, meets that the larger shear stress that breaks ground caused on the flank of tooth of native face area is larger, and resistance of dredging is larger；Taper Tooth tooth tip is taper, and flute profile is tetrahedral, and work progress embedded depth is larger, and shipping agency resistance is larger, is advanced in addition along ship It is relatively narrow to soil layer active area in direction, and effect of breaking ground is limited；Stress surface is larger in plough type tooth use process, brought shipping agency Resistance is larger, so that ship is difficult to reach ideal and dredges ship's speed.

Therefore, it needs to develop one kind specifically for silty sand soil property, and can quickly improve the rake teeth of construction effect.

Summary of the invention

The utility model is to solve technical problem present in well-known technique and provide a kind of drag suction dredger half T-type Rake teeth with ribbing, the rake teeth are half T-type, improve ability of breaking ground, improve and excavate silty sand soil property soil construction concentration, greatly improve rake The operating efficiency of Suction Dredger.

The utility model is adopted the technical scheme that solve technical problem present in well-known technique:

A kind of drag suction dredger half T-type rake teeth with ribbing, including interconnecting piece and the tooth tip that breaks ground, the root of the tooth tip that breaks ground Portion is connect with interconnecting piece, and meeting on the outside of the tooth tip that breaks ground is provided along its length a tooth rib, the tooth rib on the native flank of tooth For class Y type, two sides gradually broaden to the tooth that breaks ground the tooth rib to the left and right since with one end of the head respective side for the tooth tip that breaks ground Point root, relatively narrow one end end of the tooth rib is concordant with the head for the tooth tip that breaks ground, wider one end end of the tooth rib and Break ground tooth tip root it is concordant and connect with interconnecting piece, the left and right of the left and right sides of wider one end of the tooth rib and the tooth tip that breaks ground Two sides are concordant, and the lateral surface of the tooth rib is concordant with the lateral surface of its ipsilateral interconnecting piece.

In the above-mentioned technical solutions, it is preferred that the interconnecting piece, break ground tooth tip and tooth rib integrally casting shaping.

In the above-mentioned technical solutions, it is preferred that the width of relatively narrow one end end of the tooth rib is 0.1~1cm.

In the above-mentioned technical solutions, it is preferred that the tooth rib with a thickness of 1cm.

In the above-mentioned technical solutions, it is preferred that be machined with mounting groove on the interconnecting piece.

In the above-mentioned technical solutions, it is preferred that the interconnecting piece is square.

The rake teeth of the utility model is mounted on main drag head lower part, several rake teeths form rake teeth group, and rake teeth and horizontal plane press from both sides Angle is identical, is row's parallel device.

The utility model has the advantages and positive effects of:

The rake teeth working face of the utility model is the flank of tooth with ribbing, and the flank of tooth with ribbing is native by tooth tip cutting of breaking ground in work progress Body will meet the native flank of tooth front end soil body by tooth rib and separate two sides to the left and right；The tooth tip that breaks ground meets the stress collection of tooth rib on the native flank of tooth Middle effect can be relatively easy to destroy the soil body before the flank of tooth, and the intracorporal pore water pressure of native flank of tooth soil is met in reduction, and then is reduced Cutting resistance improves ability of breaking ground, improves and excavate hard silt soil construction concentration, broken soil is then drawn onto ship by dredge pump Body spoil hopper, greatly improves production efficiency；Meanwhile the rake teeth is easily manufactured, easy to spread uses drag suction dredger.
