Abstract

The utility model provides a chain for bi-pitch cutting, which includes an inner link and an outer link. The outer link is connected with both sides of the inner link by a pin shaft. Outer guide blades are arranged on both sides of the outer link; mounting holes for add-on cutters are arranged on one end of the outer guide blade. Cutters can be attached to the utility model, which has the advantages of efficient cutting, convenient update and replacement and applicability to stone cutting. The utility model adopts bi-pitch, i.e. the mode of short inner link and long outer link, and can increase drive gear pitch of a driving wheel when in coordination with a chain wheel, so as to improve the strength of the drive gear of the driving wheel, enhance transmission power and prolong service life. And the integration of the inner and outer links is suitable for operation under the conditions of poor lubrication and high corrosion.

Description

Bipatch cutting chain

(1) technical field

The utility model relates to the engineering machinery technology, is specifically related to a kind of native stone material cutting chain.

(2) background technology

At present, the cutting at materials such as earth, sandstones in the engineer operation all will be used large-scale excavator or rubble ditching machine with excavation, and the machine volume is big, and excavation area is big, and workload is big, and energy waste is big, and is also big to the destruction of ecological environment simultaneously.Especially cut with instrument and be difficult for dismounting and change, dumb, make that the range of application of native stone cutting machine is limited greatly.

(3) summary of the invention

The purpose of this utility model is to provide a kind of attachable cutter, efficient cutting, and the convenient bipatch cutting chain that is applicable to native stone cutting that changes that upgrades.

The purpose of this utility model is achieved in that it comprises inner link and outer link, and outer link is connected the inner link both sides by bearing pin side by side, and the outer link both sides are provided with outer guide card, and an end of outer guide card is provided with the installing hole of plug-in cutter.

The beneficial effects of the utility model have:

1, bipatch chain, can realize increasing the intensity of the driving wheel gear teeth: the utility model chain strip adoption bipatch, be that inner link is short, the form that outer link is long, when the adapted sprocket wheel, can increase the pitch of driving gear on the driving wheel, the intensity of drive wheel tooth be can increase like this, transmission power and application life increased;

2, whole interior outer link, adaptation is worked in poor lubrication, high corrosive environment: because when excavating native stone material, be difficult to guarantee the lubricated of chain and reduce wear, and native stone is corrosive again, simultaneously require chain that high guidance capability is arranged again, so the utility model adopts whole interior outer link; Whole inner link volume is big, and the convenient encapsulant that uses can store lubricated matter again more; Whole outer link (by bearing pin, with interior outer link rivet clasp) can make bearing pin fix, and prevents departing from of tractive force, can be good from guidance quality;

3, carry outer guide card, convenient guiding to chain, the protection guide strip, simultaneously can assist cutting: outer guide card can prevent effectively that chain from coming off from guide strip or gear on the outer link, can also effectively protect guide strip, reduce the wearing and tearing of native stone to guide strip, and make guide board structure simple, outer guide strip also can play auxiliary cutting and traction soil stone simultaneously;

4, attachable cutter, efficient cutting, and the convenient suitable instrument of development of new that upgrades: the outer guide card of attachable cutter suits to use instead special-purpose cutter when cutting excavation different materials, to improve effect, especially can give development of new efficiently cutting tool broad operating platform is provided.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the lateral view of Fig. 1.

(5) specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described:

In conjunction with the accompanying drawings, present embodiment comprises inner link 1 and outer link 2, and outer link 2 is connected inner link 1 both sides by bearing pin 3 side by side, and outer link 2 both sides are provided with outer guide card 5, and an end of outer guide card 5 is provided with the installing hole 7 of plug-in cutter.

Inner link was short when the utility model used, and outer link is long, should increase the pitch of driving gear on the driving wheel when the adapted sprocket wheel, and outer guide card directly acts on the guide strip or the gear outside simultaneously, can effectively guide chain engages.

Claims

1. chain is used in a bipatch cutting, and it comprises inner link and outer link, it is characterized in that described outer link is connected the inner link both sides by bearing pin side by side, and the outer link both sides are provided with outer guide card, and an end of outer guide card is provided with the installing hole of plug-in cutter.
