Abstract
The utility model relates to a cutter with a stone proof net for a cutter suction dredger, and belongs to the technical field of dredging. The cutter with the stone proof net for the cutter suction dredge comprises a cutter hub, cutter blades, cutter teeth and a cutter ring. The cutter teeth are arranged on the cutter blades; and the cutter blades are connected to the cutter hub and the cutter ring. The cutter with the stone proof net is characterized in that the cutter is provided with a stone proof net. The cutter can effectively prevent large stone blocks from entering a mud pump to avoid damage to a cylinder block, can prevent the large stone blocks from being clamped inside an impeller to avoid losing balance of a machine and avoid damage to set screws of a transmission bearing support, reduces pump efficiency attenuation rate caused by damage of the impeller of the mud pump, has the advantages of simple structure, convenient processing, low manufacturing cost, economy and practicality and the like, can prolong service life of the cylinder block and the impeller, effectively improves construction production ratio and time use ratio of digging drifting sand, gravels and broken stones.
Description
Technical field
The utility model belongs to the dredging technology field, particularly relates to a kind of cutter suntion dredger and prevents stone net reamer with band.
Background technology
At present, existing reamer is when excavating sandy gravel, rubble matter great soil group, owing to contain big particle diameter piece stone in the soil body, such piece stone enters the dredge pump the inside and very easily breaks the pump courage, increases wearing and tearing and reduces pump efficiency; The part stone is stuck in the impeller the inside disequilibrium that also can have a machine in operation, and damages drive bearing support fixed screw, causes engine-damaged accident.Cause the maintenance of the vessel time to increase, reduce the boats and ships time availability and the productivity ratio of dredging, the dredging cost is gathered increase.
Summary of the invention
The utility model is for solving the technical problem that exists in the known technology, and reamer is when excavating sandy gravel, rubble matter great soil group, and big particle diameter piece stone enters dredge pump and breaks the pump courage in the soil body, increases wearing and tearing and reduces pump efficiency; The part stone is stuck in the impeller the inside disequilibrium that also can have a machine in operation, and damages drive bearing support fixed screw, causes engine-damaged accident etc., and provides a kind of cutter suntion dredger with the anti-stone net reamer of band.
The purpose of this utility model provides a kind ofly to be had simple in structurely, easy to process, economical and practical, can prevent that ratchel from entering dredge pump and destroying the pump courage; Preventing that ratchel is stuck in makes the machine disequilibrium in the impeller, destroy power transmission shaft and become rack screw; Can improve the cutter suntion dredger of characteristics such as boats and ships efficiency of construction greatly and prevent stone net reamer with band.
The technical scheme that the utility model is taked is:
Cutter suntion dredger has reamer wheel hub, cutter piece, reamer tooth and reamer circle with the anti-stone net reamer of band, and the reamer tooth is arranged on the cutter piece, and cutter piece even is loaded on reamer wheel hub and reamer circle, is characterized in: reamer is equipped with anti-stone net.
The utility model can also adopt following technical measures:
Described cutter suntion dredger is characterized in: prevent that the stone net is a pyramidal structure with the anti-stone net reamer of band.
Described cutter suntion dredger is characterized in: prevent that the stone net is installed on reamer wheel hub and the reamer circle with the anti-stone net reamer of band.
Described cutter suntion dredger is characterized in: prevent that the stone net is welded on reamer wheel hub and the reamer circle with the anti-stone net reamer of band.
Described cutter suntion dredger is characterized in: prevent that the stone net is the welded steel fabric grating texture with the anti-stone net reamer of band.
Advantage that the utlity model has and good effect:
Cutter suntion dredger is prevented stone net reamer with band, owing to adopted technical solutions of the utility model, it is low that anti-stone net reamer has cost, make simple, can save the time of cleaning ratchel for the cutter suction dredger construction, reduce dredge pump because of the probability that ratchel damages, delay the dredging pump efficiency rate of decay, improve boats and ships Construction Productivity and time availability.
The utility model can prevent effectively that ratchel from entering dredge pump, destroys the pump courage; Preventing that ratchel is stuck in makes the machine disequilibrium destroy drive bearing support fixed screw in the impeller; Have advantages such as simple in structure, easy to process, economical and practical.

The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now also in conjunction with the accompanying drawings, be described in detail as follows:
Embodiment
With reference to accompanying drawing 1, Fig. 2 and Fig. 3.
Cutter suntion dredger has reamer wheel hub 1, cutter piece 2, reamer tooth 3 and reamer circle 4 with the anti-stone net reamer of band, and reamer tooth 3 is arranged on the cutter piece 2, and cutter piece 2 even is loaded on reamer wheel hub 1 and reamer circle 4; Stone net 5 is prevented in the taper that is welded on reamer wheel hub 1 and reamer circle 4.Anti-stone net 5 is a round steel welded mesh trellis structure.
The concrete mounting structure and the course of work of present embodiment:
Anti-stone net adopts the round steel of diameter 50mm to be made, at first measure the size of dredging pump impeller runner before the making, to determine the size of anti-stone net grid, the sizing grid of anti-stone net is according to making less than the size of dredging pump impeller runner, before the welding reinforcing bar is pressed the size of mesh opening blanking, successively single-frame welding from bottom to top will prevent that the stone net is welded on reamer wheel hub and the reamer circle, connects to an integral body with reamer.Begin to weld the first floor grid to reamer wheel hub direction from the reamer circle during making: reinforcing bar one end of well cutting is welded on the reamer circle, and along reamer circle welding one circle, two sections round steel spacings are the grid length of side.Then, the upper sideline that is parallel to reamer circle direction welding first floor grid.By that analogy, until the reamer wheel hub.So just form the taper reinforcing bar net structure that links reamer circle and reamer wheel hub, the making of anti-stone net finishes.
Anti-stone net formula reamer is made a taper net structure on the basis of original reamer when excavating chiltern, rubble matter soil property, place between reamer blade and the suction mud mouth, and its effect is: prevent that ratchel from entering the reamer suction inlet dredge pump pump courage impeller is damaged; Prevent that ratchel is stuck in the impeller the inside and makes the impeller operation disequilibrium, destroy drive bearing support fixed screw.
