Description
Technical field
It is specifically a kind of to be used for operating mechanism's cut the present invention relates to a kind of cuts such as mining machinery or break mined material equipment
Or the pick of break mined material.
Background technology
Pick-like bit is to determine coal-winning machine Cutting Performance, the critical component of operating efficiency, because condition of work is severe, is subject to
High-frequency percussion load and coal body continuous frictional, easily cause and fracture and heavy wear phenomenon, lead to not passing fault or efficiency
It is low.Jin Hua palaces ore deposit is trying mining phase, using simple structure, the pick-like bit that the depth of cut is big and energy ezpenditure is low.This pick
The pick body and tooth head of type pick are a kind of alloy steel materials, have simply applied one layer of wearing layer, thus this section in tooth head position
Tooth low intensity, causing frequently to change cannot also pass through tomography.For this problem it is proposed that a kind of split type load and unload
Pick-like bit, change the material of wearability high intensity at the position of pick rapid wear, and tooth body uses common alloy steel material.
The content of the invention
The present invention is intended to provide a kind of wearability is good, long service life split type pick-like bit.
A kind of split type pick-like bit that the present invention is provided, including hard alloy head, taper sheath, alloy steel-tooth body, cylinder
Shape covers and jump ring；It is characterized in that：The hard alloy head and alloy steel-tooth body have corresponding rectangle toothing, by rectangle
Toothing is mutually twisted the seamless connection for carrying out hard alloy head and alloy steel-tooth body, is covered on the toothholder of alloy steel-tooth body afterbody
Cylindrical shroud and draw-in groove and its jump ring are provided with, the spinning of hard alloy head is realized.
Wherein, the hard alloy head is that the sleeve made by high-abrasive material fixes pick-like bit tooth body；The hard
The outer surface of alloy head is coated with high-abrasive material.
A kind of split type pick-like bit that the invention described above is provided, compared with prior art, its advantage is：This
Invention pick-like bit is seamlessly connected using hard alloy head with steel alloy denticle, can be by pick after hard alloy head or denticle abrasion
Take apart and individually changed, not only saved the time but also about cost successively；This split type pick-like bit that the present invention is provided
Manufacturing process is simple, can mass production each several part, then assembled again；The hard of this pick-like bit that the present invention is provided
Alloy head is difficult for drop-off, and wearability and the common pick of strength ratio are good, practical.

Specific embodiment
Specific embodiment of the invention is made further instructions below in conjunction with accompanying drawing.
Above-mentioned the provided a kind of split type pick-like bit of the present invention, head directly contact when the pick-like bit works are provided
Coal petrography, coal petrography is crushed, therefore it is most easily worn, and is closed for the head of pick-like bit is used alone hard by extension cutting-gear life
Jin Gang, pick body uses common alloy steel, and is connected hard alloy head 1 and pick body 3 by being mutually twisted for rectangular teeth
It is connected together.This connection request pick body is the structure of dissection type.After hard alloy head 1 and pick body 3 are installed,
On the one hand for the tooth body that on the other hand fixed pick body contacts coal petrography part to give covers one layer of wearing layer, will be by wear-resisting material
The taper sheath 2 that material is made is enclosed within the conical surface of pick, is further to fix taper sheath, the edge that can be contacted with tooth body in taper sheath
Welded.In toothholder can be rotation due to pick-like bit, thus when work pick and toothholder contact position
Also can wear and tear, so as with the effect of taper sheath, also with the cylindrical shroud 4 being made up of high-abrasive material by pick body with
The position of toothholder contact is entangled, and the fixation of cylindrical shroud is mainly by itself and the interference fit between pick body.In pick body
Afterbody have jump-ring slot for being connected with pick base, the tooth body of pick-like bit is further fixed by jump ring 5.In work
In work, the hard alloy head of the pick-like bit that the present invention is provided can be rotation, be conducive to uniform wear, and the pick to be
It is split type removably, a certain position, such as hard alloy head or tooth body, can be taken pick-shaped cutter apart after damage is carried out to damaged part
Change, not only saved the time but also cost-effective.
Certainly, described above not limitation of the present invention, the present invention is also not limited to the example above, the art
Change, remodeling, addition or replacement that those of ordinary skill is done in essential scope of the invention, fall within protection of the invention
Scope.
The specific embodiment of the invention described above is by pick head most easy to wear according to the work characteristics of pick-like bit
Wearability and the preferable Hardmetal materials of intensity are used alone, tooth body uses more common alloy steel material.In order to make
The tooth head that hard alloy is made and the tooth body that steel alloy is made are realized being seamlessly connected, and the present invention is devised in their connecting portion
Rectangular teeth, tooth body is dissection type, by rectangular teeth be mutually twisted connect hard alloy head and alloy steel-tooth body will not be right
Pick material is damaged, and hard alloy head can be realized rotating during coal petrography cutting, be conducive to uniform wear.By
The tooth body made in steel alloy is dissection type, in order to two halves tooth body is fixed together, the invention provides one kind by wear-resisting
The taper sheath that material is made, is enclosed within the conical surface of pick-like bit by by taper sheath, both can fixing tooth body but also as wearing layer.
Due to can be rotation in toothholder of the pick-like bit on roller, therefore pick also has with the contact site of toothholder to wearability
Certain requirement, so being enclosed within what pick was contacted with toothholder the invention provides a kind of cylindrical sleeve made by high-abrasive material
Position, its effect is as taper sheath effect above.There is the jump-ring slot being connected with pick base in the afterbody of tooth body, pass through
Jump ring further fixes the tooth body of pick-like bit.
