Abstract

The utility model relates to a pivot for silt remover, including a main shaft, be equipped with helical blade on the main shaft, helical blade includes forward helical blade and reverse helical blade be equipped with the guide plate that is used for being connected two blades between forward helical blade and the reverse helical blade. The utility model discloses an adopt one end to set up the forward helical blade other end in the pivot and set up reverse helical blade, during the rotation, through reverse helical blade's reverse impact power, reduce silt that the part was carried by the forward helical blade impact force to equipment to set up the guide plate between forward helical blade and reverse helical blade, play the effect that enlarges the blowdown bore, guarantee the smooth and easy discharge of silt, solve the problem of stopping up.

Description

A kind of rotating shaft for dredger
Technical field
The utility model relates to hydraulic engineering field, particularly relates to a kind of rotating shaft for dredger.
Background technology
In the construction of hydraulic engineering, often need to use desilting equipment.Desilting equipment comprises conveying device, and the parts of conveying device are the screw rods for transmitting mud, and screw rod is provided with equally distributed helical blade, is rotated by helical feed driven by motor screw rod.Usually, for ensureing that mud is carried smoothly, need larger rotating speed, the mud being transported to silt collecting box can produce greater impact power to the dividing plate of upper end, and Long-Time Service is comparatively large to equipment damage, and then affects application life.And owing to there are more dregs in mud, the problem often having blocking occurs.
Utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of rational in infrastructure, not easily blocks, the rotating shaft for dredger of long service life.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of rotating shaft for dredger, comprise main shaft, described main shaft is provided with helical blade, described helical blade comprises transport screw blade and reverse acting spiral blade, at described transport screw blade and the deflector be provided with between reverse acting spiral blade for being connected two blades.
Further, the quantity ratio of described transport screw blade and reverse acting spiral blade is 4:1.
Further, described deflector is placed in described rotating shaft centre position, and is in same plane with described rotating shaft core.
Compared with prior art, the utility model has the advantage of: rotating shaft of the present utility model adopts one end the transport screw blade other end is set and reverse acting spiral blade is set, during rotation, by the reverse impact power of reverse acting spiral blade, the mud that reduction part is carried by transport screw blade to the impact force of equipment, and arranges deflector between transport screw blade and reverse helical blade, plays the effect expanding blowdown bore, ensure the smooth and easy discharge of mud, solve the problem of blocking.
Accompanying drawing explanation
Fig. 1 is a kind of pivot structure schematic diagram for dredger of the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based in the utility model being embodiment, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, for a rotating shaft for dredger, comprise main shaft, described main shaft 1 is provided with helical blade, described helical blade comprises transport screw blade 2 and reverse acting spiral blade 3, at described transport screw blade 2 and the deflector 4 be provided with between reverse acting spiral blade 3 for being connected two blades.Described transport screw blade 2 is 4: 1 with the quantity ratio of reverse acting spiral blade 3.Described deflector 4 is placed in described rotating shaft centre position, and is in same plane with described rotating shaft core.
Compared with prior art, the utility model has the advantage of: rotating shaft of the present utility model adopts one end the transport screw blade other end is set and reverse acting spiral blade is set, during rotation, by the reverse impact power of reverse acting spiral blade, the mud that reduction part is carried by transport screw blade to the impact force of equipment, and arranges deflector between transport screw blade and reverse helical blade, plays the effect expanding blowdown bore, ensure the smooth and easy discharge of mud, solve the problem of blocking.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in foregoing embodiments, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.

Claims (3)
