Abstract
The utility model relates to a movable tooth type reamer for a dredger. A reamer shelf is provided with movable teeth which are composed of a tooth seat (1) and a tooth body (2) which are tightly fixed by a pin (3). The lower end of a Holland IH tooth seat is provided with a bulge with an elliptical sectional plane. The end part of the bulge is provided with a cylinder-shaped navel. The upper end of the tooth body is provided with a cavity corresponding to the bulge and the cylinder-shaped navel. The tooth seat is welded on the reamer shelf. The tooth body is inserted into the tooth seat, penetrates the pin and is plugged into a rubber pad. The utility model has interchangeability, the teeth of the utility model have long service life and can be repaired and changed, and the utility model increases the dredging efficiency.
Description
A kind of Cutters for Dredgers of active flute profile
Reamer is the main vulnerable part that cutter suction dredger is used for mining clay, and China introduced 4600 types combination cutter suction dredger by Holland in 1974.Owing in work progress, run into the soil property that hard difficulty is dug, cause the abrasion of IHC-B type reamer serious, production efficiency and construction all do not reach original index, in order to prolong the application life of reamer, press the cutter piece of dress with the plasma spray high-abrasive material on IHC-B type reamer frame.Even so, often change the drawback of cutter piece, still do not obtain satisfied solution.
The purpose of this utility model is to provide a kind of novel cutter suction dredger reamer series in order to overcome above-mentioned the deficiencies in the prior art.
Purpose of the present invention can reach by following measure: after the Japanese active type strand tooth of introducing in 1985 is carried out design improvement, with the combination of IHC-B type reamer frame, be formed for the active type strand tooth of cutter suction dredger reamer.It is characterized in that adopting the matching part of external cutter tooth and toothholder (1), the cutter suction dredger specific design of making according to IHC Holland NV the geometric shape size, will be with surfacing wear-resistant metal material on the denticle (2) of high-alloy steel casting.On the reamer frame,, replace former cutter piece by adorning this active type strand tooth that has.
The Cutters for Dredgers of active flute profile by toothholder (2) and denticle (1) by pin (3) fastening composition.
Lower end in toothholder (1), it is ellipse garden shape ledge that a vertical section is arranged, and in the end of shape lower end, ellipse garden ledge, the navel of a garden cylindricality is arranged.Upper end in denticle (2) with the corresponding position of navel of toothholder (1) ellipse garden shape ledge and garden cylindricality, has a size to be slightly larger than the chamber of toothholder (1) ellipse garden ledge and garden post navel.When toothholder (1) inserts denticle (2) chamber, between the chamber wall of the outstanding position of toothholder (1) and denticle (2) with not loose spacious being as the criterion.
On the reamer frame when adorning active type strand tooth, toothholder (1) is welded on the reamer frame, in the upper end square hole of toothholder (1), fill in the notched rubber pad of hard (4) then, again denticle (2) is inserted on the toothholder (1), put on square pin (3), like this, square pin (3) is squeezed solid in square opening by rubber pad (4).
Toothholder (1) and denticle (2) all are to use the high strength alloy steel casting, and the working surface that it contacts with silt particle is with plasma spray one deck wear-resistant metal material.Active type strand tooth is welded on the reamer frame.
According to the difference of dredger dredging navigation channel soil property, denticle (2) can be made pointed, inclined to one side shape, garden shape or square.Nationality is to improve dredging efficiency.
The Cutters for Dredgers of this active flute profile, has commutativity, the strand tooth that the neck abrasion can be twisted faster tooth and root in the construction of strand mud exchanges in due course, and this active type twists the application life of tooth, can meet or exceed the application life of surfacing IHC-B type cutter tooth.Because reamer is active type strand tooth, and is rational in infrastructure, cheap, has high abrasion resistance, also improved the production efficiency of dredge boat simultaneously.
