Abstract
The utility model relates to a drag head for a dredge boat, and particularly relates to a drag head with rake teeth and a spring for dredge boat, wherein the drag head is capable of working on a hard soil layer. The drag head comprises a steel cable (1), a drag head upper plate (2), the spring (3), a drag head lower plate (4), the rake teeth (5) and a drag head body (6), wherein the drag head body (6) is provided with a steel cable support plate (10); the steel cable support plate (10) is connected with the steel cable (1); and the rake teeth (5) are provided with the spring (3). Through the adoption of the drag head provided by the utility model, a self-propelled drag-suction dredge boat is enabled to work normally in an area where construction cannot be carried out, and the effects of energy conservation and high efficiency are achieved in all aspects.
Description
Technical field
The utility model relates to the drag head that a kind of dredge boat is used, especially relate to a kind of can be at the dredge boat rake teeth band spring drag head of hard soil layer operation.
Background technology
Drag head is the equipment foremost that the formula dredge boat is used for drawing mud or silt pipeline, and the digging action of drag head comprises that sluicing, mechanical type excavate, and the drag head structure can influence efficient and the effect of entire job process.At present the drag head used of dredge boat can be finished the operation of drawing silt, but efficient is not high, vibrations big, can not be in hard soil layer operation etc.
Summary of the invention
Efficient is not high, the big problem of vibrations at existing in the prior art for the utility model, and the drag head that a kind of efficient height, vibrations are little, can use at the trailing suction hopper dredger of hard soil layer operation is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals.
Dredge boat rake teeth band spring drag head comprises wirerope, drag head upper plate, spring, drag head lower plate, rake teeth and drag head body, and the drag head body is provided with wirerope support plate wirerope support plate and is connected with wirerope, and rake teeth is provided with spring.
Rational in infrastructure, spring can reduce the vibrations of rake teeth and the scope of operation.
As preferably, rake teeth is provided with drag head upper plate and drag head lower plate, is provided with spring between drag head upper plate and the drag head lower plate.Can improve rake teeth to the adaptive capacity of closely knit soil, reduce excavating resistance, the auxiliary function of breaking ground.
As preferably, the drag head upper plate all is connected with rotating shaft with the drag head lower plate.Rotation shaft regulated flexibly, excavate closely knit pan soil, rock is efficient.
As preferably, rake teeth is provided with rotating shaft, and rotating shaft is connected with the drag head body by wirerope.Flexible and efficient, handled easily.
As preferably, the drag head body is provided with dredging tube.Can get rid of muddy water.
The utility model is owing to adopted above technical scheme, and the drag head body is provided with spring, and spring structure is reasonable, from solved the not high problem of drag head operating efficiency at all.
