Description
Technical field
The utility model relates to chain structure field more particularly to a kind of chain links of mud scraper.
Background technique
Mud scraper is a kind of common sewage apparatus, is mounted in sedimentation basin, the sludge settling in sewage scrapes mud in bottom of pond
Machine into collection mud pit, is discharged sludge scraping collection sludge using sludge pump.
Mud scraper is mainly by cleaning shoe, chain, drive sprocket, driven sprocket and high power motor composition.This whole set of
Inside equipment, it is desirable that highest is chain, when chain is broken, will cause cleaning shoe both sides and walks asynchronous, can will scrape
Mud plate is torn in shreds, and be will cause whole pond if serious and is collapsed.For this purpose, the quality of chain is most important.
Chain can be subdivided into three components, chain link, pin shaft and circlip.Chain link includes head and tail portion, and head is provided with
First sleeve, tail portion setting there are two second sleeve spaced apart, first sleeve by two linking arms respectively with two second
Sleeve connection.The first sleeve of previous chain link and the second sleeve face of latter chain link are simultaneously located between two second sleeves, pin
Axis is connect after first sleeve and second sleeve with circlip, so that chain link be made to be linked to be chain.
Chain link is pulled off in order to prevent, and the linking arm of traditional chain link is made very thick, this makes the volume of entire chain link big
With weight weight, and since a chain includes large number of chain link, this makes whole chain quality very big, expends in operation
Power it is also more.
For this reason, it may be necessary to propose to improve aiming at the problems existing in the prior art.
Utility model content
The purpose of this utility model is to provide a kind of chain link of mud scraper, small in size and light weight.
To achieve the above object, the utility model provides a kind of chain link of mud scraper comprising head, tail portion and
Linking arm, the head are provided with first sleeve, and there are two second sleeve spaced apart, first sleeve passes through for the tail portion setting
Two linking arms are connect with two second sleeves respectively, are enclosed in every linking arm along the length side of the linking arm
To the steel bar of extension.
Further, the chain link is polyformaldehyde injection molding body.
Further, the outer side surface of every linking arm is provided with the reinforcing rib for the truncated wedge that 3 are set side by side,
Every reinforcing rib includes the first right-angle side, the second right-angle side and bevel edge；It is located in the middle the first right-angle side of reinforcing rib and outer
Side wall surface connection, the second right-angle side are connect with first sleeve；The first right-angle side and outer side surface positioned at the reinforcing rib of two sides connect
It connects, the second right-angle side is connect with second sleeve.
Further, the both ends of the steel bar are provided with jagged fixed part.
Further, waveform or arc are set as in the middle part of the steel bar.
Further, the diameter of the steel bar is 1-2mm.
Further, steel bar described in 3-5 item is enclosed in every linking arm.
A kind of chain link of mud scraper provided by the utility model, it in linking arm by wrapping up compared with the prior art
After being enclosed with steel bar, the thickness of linking arm can be suitably thinned to increase the intensity of linking arm in steel bar, so that entire chain link
Volume is smaller, and quality is lighter, and the power expended in operation is also reduced.

Specific embodiment
It elaborates below in conjunction with specific embodiment to the invention.
The utility model provides a kind of chain link of mud scraper, as depicted in figs. 1 and 2 comprising head, tail portion and connection
Arm 2, head are provided with first sleeve 11, and there are two second sleeve 12 spaced apart, first sleeves 11 to pass through two for tail portion setting
Linking arm 2 is connect with two second sleeves 12 respectively, and the length direction extension along linking arm 2 is enclosed in every linking arm 2
Steel bar 3.
Based on above-mentioned structure, the chain link of mud scraper in linking arm 2 by wrapping up steel bar 3, to increase the strong of linking arm 2
Degree, after being enclosed with steel bar 3, can suitably be thinned the thickness of linking arm 2, so that the volume of entire chain link is smaller, quality is lighter,
The power expended when operation is also reduced.Meanwhile even if the main body of linking arm 2 is broken, and since still there is steel bar 3 in inside,
Steel bar 3 has certain tensile strength, and steel bar 3 remains to support a period of time, is unlikely to disconnect at once.
In the present embodiment, chain link is polyformaldehyde injection molding body.Raw material using polyformaldehyde as injection molding enable to chain
Section has higher intensity.
In the present embodiment, the outer side surface 21 of every linking arm 2 is provided with the reinforcement for the truncated wedge that 3 are set side by side
Muscle 4, every reinforcing rib 4 include the first right-angle side 41, the second right-angle side 42 and bevel edge 43；As shown in figure 3, being located in the middle
First right-angle side 41 of reinforcing rib 4 is connect with outer side surface 21, and the second right-angle side 42 is connect with first sleeve 11；Positioned at two sides
First right-angle side 41 of reinforcing rib 4 is connect with outer side surface 21, and the second right-angle side 42 is connect with second sleeve 12, and structural principle can
Referring to Fig. 3.Reinforcing rib 4 is set by the outer side surface 21 in linking arm 2, can be improved the tensile strength of entire chain link, reinforce
The presence of muscle 4 can make the bonding strength between linking arm 2 and first sleeve 11 and second sleeve 12 higher, and use voussoir
The reinforcing rib 4 of shape can also reduce the use of material as connection structure, so that the weight of entire chain link is lighter.
In the present embodiment, the both ends of steel bar 3 are provided with jagged fixed part 31, make steel by the fixed part 31
Connection between item 3 and injection molding body is closer, and after injection molding body is broken, the steel bar 3 for providing interim connection function still can
It is enough to be closely joined together with injection molding body, it will not be pulled easily.Preferably, the middle part of steel bar 3 is set as waveform or arc,
After injection molding body is broken, the steel bar 3 of waveform or arc is pulled straight but is not torn, and injection molding body is slightly separated, and is convenient for work
Make to see the presence gone wrong when personnel inspection easily, the steel bar 3 of waveform or arc can also successfully manage the band that expands with heat and contract with cold
The negative effect come.It is further preferred that the diameter of steel bar 3 is 1-2mm, steel described in 3-5 item is enclosed in every linking arm 2
Item 3.
Based on above-mentioned structure, in destructive testing, highest tensile strength reaches the chain link of the mud scraper of the utility model
To 3 tons, the probability that product is damaged due to stretching is greatly reduced.
In the absence of conflict, the feature in the above embodiments and embodiment can be combined with each other.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the invention, rather than to this hair
It is bright create protection scope limitation, although being explained in detail referring to preferred embodiment to the invention, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the invention, without departing from this
The spirit and scope of innovation and creation technical solution.
