Abstract
The utility model discloses a drag head device, comprising a rear row rake teeth high pressure flushing flexible pipe, an active drag head hydraulic cylinder, a high pressure flushing pipeline, a front row rake teeth high pressure flushing flexible pipe, a base and a single row tooth tip rake teeth. The rear row rake teeth high pressure flushing flexible pipe is disposed between the active drag head hydraulic cylinder and the front row rake teeth high pressure flushing flexible pipe. The high pressure flushing pipeline is disposed between the front row rake teeth high pressure flushing flexible pipes. The rear row rake teeth high pressure flushing flexible pipe, the active drag head hydraulic cylinder, the high pressure flushing pipeline and the front row rake teeth high pressure flushing flexible pipe are fixed above the base. The single row tooth tip rake teeth are fixed beneath the base. The drag head device can improve the density of dredging dense fine sand.
Description
Technical field
The utility model relates to a kind of device of boats and ships, particularly a kind of drag head device.
Background technology
The normally used rake teeth of drag head device of trailing suction hopper dredger has cutter type tooth, sharp type tooth, plough type tooth, and the rake teeth interlocking is installed on the rake teeth seat of drag head.Existing drag head device is dredged density when digging closely knit fine sand only at 1.1t/m in the entrance of Changjiang River
3About, with fine sand 1.25t/m in the excavation
3Above density differs greatly.
The utility model content
The utility model technical problem to be solved provides a kind of drag head device, and the density when digging closely knit fine sand is dredged in its raising.
For solveing the technical problem; The utility model provides a kind of drag head device; It is characterized in that; It comprises back row's rake teeth high-pressure flush flexible pipe, active drag head hydraulic cylinder, high-pressure flush pipeline, front-seat rake teeth high-pressure flush flexible pipe, base, single crown rake teeth, and back row's rake teeth high-pressure flush flexible pipe is located between active drag head hydraulic cylinder and the front-seat rake teeth high-pressure flush flexible pipe, and the high-pressure flush pipeline is located between the front-seat rake teeth high-pressure flush flexible pipe; Back row's rake teeth high-pressure flush flexible pipe, active drag head hydraulic cylinder, high-pressure flush pipeline, front-seat rake teeth high-pressure flush flexible pipe are fixed on the top of base, and single crown rake teeth is fixed on the below of base.
The positive progressive effect of the utility model is: the utility model drag head device improves the density dredge when digging closely knit fine sand.
Description of drawings
Fig. 1 is the vertical view of the utility model drag head device.
Fig. 2 is the lateral view of the utility model drag head device.
The specific embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As depicted in figs. 1 and 2; The utility model drag head device comprises back row's rake teeth high-pressure flush flexible pipe 1, active drag head hydraulic cylinder 2, high-pressure flush pipeline 3, front-seat rake teeth high-pressure flush flexible pipe 4, base 5, single crown rake teeth 6; Back row's rake teeth high-pressure flush flexible pipe 1 is located between active drag head hydraulic cylinder 2 and the front-seat rake teeth high-pressure flush flexible pipe 4; High-pressure flush pipeline 3 is located between the front-seat rake teeth high-pressure flush flexible pipe 4; Back row's rake teeth high-pressure flush flexible pipe 1, active drag head hydraulic cylinder 2, high-pressure flush pipeline 3, front-seat rake teeth high-pressure flush flexible pipe 4 are fixed on the top of base 5, and single crown rake teeth 6 is fixed on the below of base 5.
The utility model drag head device improves the degree of depth of breaking ground through single crown rake teeth, improves the density of dredging when digging closely knit fine sand simultaneously.The bath of high-pressure flush pipeline inject high pressure is to reduce cutting force; The active drag head hydraulic cylinder provides power for single crown rake teeth; Back row's rake teeth high-pressure flush flexible pipe, front-seat rake teeth high-pressure flush flexible pipe supply water to mixture and make dredging soil pass through dredging tube more swimmingly.
Though more than described the specific embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these embodiments.Therefore, the protection domain of the utility model is limited appended claims.
