Abstract
A novel super-wide harrow head suitable for sludge construction comprises an active harrow head which includes wear-resistant blocks, high-pressure water filling nozzles, wedge-shape chutes and front harrow teeth. The high-pressure water filling nozzles are arranged on a plurality of wear-resistant blocks, one wedge-shape chute is arranged between every two adjacent wear-resistant blocks, the front harrow teeth includes assembly location portions, and the front harrow teeth are arranged on the wedge-shape chutes through the assembly location portions. The width of the active harrow head is equal to or larger than 200 cm. The novel super-wide harrow head suitable for sludge construction has the advantages that slurry density and channeling evenness are improved during engineering construction in sludge, and with the arranged wedge-shape chutes, assembling and unassembling of the front harrow teeth are more convenient and repair time of changing harrow teeth for the harrow head is reduced.
Description
Technical field
The utility model relates to boats and ships construction equipment technical field, especially relates to a kind of novel super wide drag head of suitable mud construction.
Background technology
After in a few years bigger navigation channel infrastructure, the channel maintenance engineering quantity also increases thereupon, and the dredging soil property is mud substantially in the channel maintenance engineering, soil property when capital construction is excavated relatively is softer, the drag head resistance of dredging is also less, how rationalization's drag head physical dimension becomes concentration of hydraulic mixture and grooving planeness when how to improve the construction of trailing suction hopper dredger mud, thereby improves the key point of the efficiency of construction of dredging.
The utility model content
Goal of the invention of the present utility model is to invent a kind of novel super wide drag head of suitable mud construction, so that address the above problem.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is as follows:
A kind of novel super wide drag head of suitable mud construction, comprise active drag head, described active drag head comprises wear-resistant block, the high-pressure flush nozzle, wedge shape chute and preceding rake teeth, described high-pressure flush nozzle is arranged on the described wear-resistant block, described wear-resistant block has between a plurality of two described wear-resistant blocks that face mutually a described wedge shape chute is set, rake teeth comprises installing and locating portion before described, the outline of the described installing and locating portion of rake teeth cooperates with the interior profile phase of described wedge shape chute before described, rake teeth is by being installed on the described wedge shape chute of described installing and locating portion interference fit before described, and the width of described active drag head is more than or equal to 200cm.
The width of described active drag head is 244cm.
The beneficial effects of the utility model are as follows:
1. the utility model can improve concentration of hydraulic mixture and grooving planeness when the engineering construction of mud soil property.
2. the utility model is provided with the wedge shape chute, can conveniently assemble and disassemble before rake teeth, reduce the repairing time that original drag head is changed rake teeth.
Description of drawings
Fig. 1 is the structural representation that the utility model master looks;
Fig. 2 is the structural representation that the utility model is overlooked;
Fig. 3 is the sectional view of Fig. 1 at the A-A place.
The specific embodiment
Below in conjunction with accompanying drawing, describe the utility model optimized technical scheme in detail.
As Fig. 1, Fig. 2, the novel super wide drag head of a kind of suitable mud construction shown in Figure 3, comprise active drag head 1, described active drag head 1 comprises wear-resistant block 6, high-pressure flush nozzle 2, wedge shape chute 3 and preceding rake teeth 4, described high-pressure flush nozzle 2 is arranged on the described wear-resistant block 6, described wear-resistant block 6 has a plurality of, between two described wear-resistant blocks 6 that face mutually a described wedge shape chute 3 is set, rake teeth 4 comprises installing and locating portion before described, rake teeth 4 is installed on the described wedge shape chute by described installing and locating portion before described, the outline of the described installing and locating portion of rake teeth 4 cooperates with the interior profile phase of described wedge shape chute before described, and the width of described active drag head 1 is 244cm.
At first the active drag head 1 of prior art is reequiped in the present embodiment, on original basis, widen, and wedge shape chute 3 is set at 2 at high-pressure flush nozzle, (wedge shape chute 3 is provided with by adjacent wear-resistant block 6 and forms, wear-resistant block 6 is provided with high-pressure flush nozzle 2), satisfy the needs that the preceding rake teeth 4 of different model is installed.Novel super wide drag head has increased when drag head lands and the contact area on ground, under the enough situation of dredge pump vacuum, improved the area of dredging in the unit interval, and the increase of drag head width has increased quantity that rake teeth can be installed (because the mud soil property is softer, so the ship resistance increases not quite after increasing rake teeth, thrust power can satisfy the required speed of a ship or plane), increased the ablation volume after rake teeth buries, and the rake pipe caliber behind the drag head changes not, therefore improved the construction concentration of hydraulic mixture.Secondly, the use of widening active drag head 1 has also played great role to the raising of the planeness in navigation channel, and every rake construction width strengthens, and under construction track density the same terms, the construction area coverage strengthens, and improves integral smoothness.As shown in Figure 3,6 of described wear-resistant blocks widening drag head leave wedge shape chute 3, can conveniently assemble and disassemble before rake teeth 4, reduce the repairing time that original drag head is changed rake teeth.
More than by the detailed description of concrete and preferred embodiment the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within spirit of the present utility model and principle; any modification of being done, be equal to replacement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. the novel super wide drag head of a suitable mud construction, it is characterized in that: comprise active drag head, described active drag head comprises wear-resistant block, the high-pressure flush nozzle, wedge shape chute and preceding rake teeth, described high-pressure flush nozzle is arranged on the described wear-resistant block, described wear-resistant block has a plurality of, a described wedge shape chute is set between two described wear-resistant blocks that face mutually, rake teeth comprises installing and locating portion before described, the outline of the described installing and locating portion of rake teeth cooperates with the interior profile phase of described wedge shape chute before described, rake teeth is by being installed on the described wedge shape chute of described installing and locating portion interference fit before described, and the width of described active drag head is more than or equal to 200cm.
2. the novel super wide drag head of suitable mud construction according to claim 1, it is characterized in that: the width of described active drag head is 244cm.
