Abstract
The utility model relates to a milling-cutting mud-suction mechanism which is used for an underwater mud-suction dredging machine, comprising a cutter head, cutter teeth, s cutter shaft, a supporting cylinder and an antifriction rubber bearing. Four cutter teeth are arranged on the outer circumference of the cutter head; each of the cutter teeth is provided with 8 gear teeth. Some cutter teeth are in linear type; some cutter teeth are in arc line type. The gear teeth on the cutter teeth are symmetrical, bidirectional and arc-shaped teeth. The gear teeth corresponding to the cutter teeth are staggeringly arranged. The utility model has the advantages that cutters can positive and reversely mill and cut the earth when the bidirectional gear teeth on the cutter teeth of the cutter head is in bilateral scanning feed and feed depth, the earth can be digged out continuously in high efficiency, the rigidity and the firmness of the cutter shaft are good, the milling-cutting mud-suction mechanism has high safety.
Description
The utility model relates to and a kind ofly be used for continuously or repeat the scanning suction dredge structure that the tilting two-way rotary-cutting type reamer head of direct connection is housed on the mud-suction dredging machine under water of work---the milling-cutting mud-suction mechanism of mud-suction dredging machine under water.
Prior art has four kinds, as: one, towards suction formula dredger, it is to break ground by clarified water pump waterpower, inhales soil with slush pump, though advantage of simple structure is arranged, it is low that it has the mud of suction concentration, and hardboard soil breaking capacity is little, and the unit interval mud volume is few.Two, strand suction formula suction dredge, its a strand horizontal, unidirectional rotary-cut is broken ground, and inhales soil with slush pump, its structure more complicated, hardboard soil breaking capacity is also less, and consumable accessory is many, and the life-span is short, poor reliability.Three, dredge boat, its cost is very high, and concentration of hydraulic mixture is low, and mud volume is few during reverse scan, the transportation difficulty, the scope of application is little.Four, submersible type dredger, mud extraction concentration is low can not the large tracts of land continuous operation.
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of tilting two-way rotary-cutting type reamer head scanning suction dredge structure of direct connection---milling-cutting mud-suction mechanism that is equipped with.
Technical solution of the present utility model: it comprises reamer head, cutter tooth 1, reamer axle 10, support tube 15, abrasive rubber bearing 19, the outer garden of reamer head is furnished with four cutters tooth 1 on week, 8 teeth are arranged on the every cutter tooth 1, cutter tooth 1 has linear pattern or arc line type, teeth on the cutter tooth 1 be symmetric double to the arc tooth, the teeth of cutter tooth correspondence are staggered.
Advantage of the present utility model:
Two-way teeth on the reamer head cutter tooth are when bilateral scanning feeding, depth, the reamer head is just being carried out, upmilling is cut soil, the purpose of can reach continuously, efficiently being unearthed, reamer axle support tube in the upper end by bearings, the lower end is supported by the abrasive rubber bearing, can increase reamer axle rigidity and steadiness, safe and reliable.
Accompanying drawing 1 is the structural representation of reamer head.
Accompanying drawing 2 is structural representations of the present utility model.
Among the figure 1 is straight knife tooth, the 2nd, arc cutter tooth, the 3rd, last circle, the 4th, support plate, the 5th, trivial jack panel, the 6th, tapered sleeve, the 7th, pressing plate, the 8th, rubber axle bed, the 9th, rubber shaft bearing, the 10th, reamer axle, the 11st, last volume, the 12nd, rubber bracer, the 13rd, fagging, the 14th, suction inlet, the 15th, supporting seat, the 16th, oil sealing, the 17th, bearing, the 18th, spline adapter sleeve.
Further describe the course of work of the present utility model below in conjunction with accompanying drawing:
The cutter tooth 1 that a plurality of two-way teeth of four arrangements are arranged on the reamer head, the small end of reamer head with by motor by the transmission case body speed change to the reamer axle 10 of forward and reverse running, the big end of dead axle circle tapered sleeve binding on the reamer axle 10 contacts with 12 3 of supporting seat block rubbers, can obtain firm forward and reverse running like this.Reamer head and plane, riverbed are tilting with the reamer axle; during work; the reamer head can be done forward and reverse rotatablely moving; two-way teeth on the reamer head cutter tooth are all in conjunction with the positive and negative milling in scanning direction; broken long-pending soil; and a long-pending soil is drawn close to reamer head center; form moment and separate by centrifugal force and reamer head footpath clear water or low concentration mud towards periphery; the what at reamer head center is native or draw close long-pending native; the mud that forms big concentration at reamer head lumen is served bank by the slush pump suction; the bilateral scanning feeding; during depth; the reversible milling soil of reamer head, thus reach continuous; efficient purpose of being unearthed, reamer axle 10 with support tube in the upper end by bearings; three outside framework oil seal 16 sealings; support by abrasive rubber bearing 9 in the lower end, increased reamer axle rigidity and steadiness, safe and reliable.
