Abstract
A ditching machine chain, comprises the first outer plate, the second outer plate, inner link, and described the second outer plate is provided with alloy blade, and described the first outer plate, the second outer plate are by bearing pin and inner link interference fit.A kind of ditching machine chain of the utility model, improves the sleeve roller chain of existing standard pitch, installs the alloy blade that ditching machine is used additional, and alloy blade and chain hinge pin adopt oblate interference fit.This chain design is reasonable, simple in structure, part-subassemble standard degree is high, is convenient to the maintain and replace of annex, is applicable to tubing ditching machine.
Description
Technical field
The utility model relates to a kind of chain, particularly a kind of ditching machine chain.
Background technology
In prior art, before conventional tubing, mostly adopt artificial trench digging, grooving.Minority is utilized the also unformed standardized product of equipment operating, and product quality is uneven, and service efficiency is low, and cost of production is high.Owing to there is no fixing production standard, annex is joined type buying difficulty, has a strong impact on the promotion and application of the type supporting machinery simultaneously.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of ditching machine chain, and the sleeve roller chain of existing standard pitch is improved, and installs the alloy blade that ditching machine is used additional, and alloy blade and chain hinge pin adopt oblate interference fit.This chain design is reasonable, simple in structure, part-subassemble standard degree is high, is convenient to the maintain and replace of annex, is applicable to tubing ditching machine.
The technical scheme that the utility model is taked is: a kind of ditching machine chain, comprise the first outer plate, the second outer plate, inner link, and described the second outer plate is provided with alloy blade, and described the first outer plate, the second outer plate are by bearing pin and inner link interference fit.
Described inner link comprises two inner plates, sleeve, roller, and roller is between two inner plates, and roller sleeve is on sleeve, and bearing pin assembles with described the first outer plate, the second outer plate after passing two inner plates, sleeve.
Described the second outer plate that is provided with alloy blade is staggered pattern and is positioned at inner link both sides and fixes assembling by bearing pin.
Described alloy blade offers two flat holes, and with bearing pin interference fit, the pitch-row in two flat holes is chain pitch.
Described bearing pin is than common chain pin axial length, and described bearing pin is oblate side's shape for assembling one end of alloy blade.
A kind of ditching machine chain of the utility model, special trench-digging machine alloy blade and chain hinge pin adopt oblate interference fit, effectively prevent that it is because relatively rotating the wearing and tearing aggravation causing, side pressure strength while simultaneously increasing blade work, for preventing that annex from coming off, after being pressed into bearing pin, plug welding polishes, and postwelding destressing is processed.The utility model chain connects the bearing pin of inside and outside chain link, than general
Logical chain hinge pin is slightly long, to guarantee itself and the erection welding of alloy furrowing machine knife sheet.Alloy blade offers two flat holes, and one end bearing pin that wherein assembles alloy blade is processed into oblate side, is pressed into rear plug welding with the flat hole of alloy blade, when preventing that blade is stressed and bearing pin relatively rotate and cause wearing and tearing and impact is normal uses.
Accompanying drawing explanation
Fig. 1 is the utility model chain side-looking structural representation;
Fig. 2 is the utility model chain perspective view;
Fig. 3 is alloy blade structural representation one of the present utility model;
Fig. 4 is alloy blade structural representation two of the present utility model.
The specific embodiment
As shown in Fig. 1 ~ Fig. 4, a kind of ditching machine chain, comprises outer link, inner link 4, and described outer link comprises the first outer plate 2, the second outer plate 1, and described the second outer plate 1 is provided with alloy blade 3, and described the first outer plate 2 is common outer plate.Described the first outer plate 2, the second outer plate 1 are by bearing pin 5 and inner link 4 interference fit.Described inner link 4 comprises two inner plates 6, sleeve 7, roller 8, and roller 8 is between two inner plates 6, and roller 8 is enclosed within on sleeve 7, and bearing pin 5 assembles with described the first outer plate 2, the second outer plate 1 after passing two inner plates 6, sleeve 7.
Each outer link includes one with the second outer plate 1 of alloy blade 3, and this second outer plate 1 is staggered pattern and is positioned at inner link 4 both sides and is pressed into plug welding by bearing pin 5.
The alloy blade 3 of ditching machine is alloy material, through heat treatment, reaches some strength, and described alloy blade 3 offers two flat holes 9, and with bearing pin 5 interference fit, the pitch-row in two flat holes 9 is chain pitch.
Described bearing pin 5 is slightly longer than common chain hinge pin, to guarantee itself and the erection welding of alloy furrowing machine knife sheet.
Described bearing pin 5 is oblate side's shape for turning one end of gold conjugate blade 3, is pressed into rear plug welding with two flat holes 9 of alloy blade 3, when preventing that alloy blade 3 is stressed, relatively rotates with bearing pin 5, causes wearing and tearing and impact is normal uses.
Each parts and accessories of the present utility model all process to reach corresponding tension and yield strength by available heat.
