Specific embodiment
It elaborates below in conjunction with specific embodiment to the invention.
The utility model provides a kind of chain of mud scraper, as shown in Figures 1 to 5 comprising multiple groups chain link 1, pin shaft 2
With circlip 3；Chain link 1 is polyformaldehyde injection molding body comprising head, tail portion and linking arm 13, head are provided with first sleeve 11, tail
Portion's setting there are two second sleeve 12 spaced apart, first sleeve 11 by two linking arms 13 respectively with two second sleeves 12
It connects, the steel bar 131 of the length direction extension along linking arm 13 is enclosed in every linking arm 13；Pin shaft 2 includes polyformaldehyde
Exterior layer and the glass fibre axle center being wrapped in polyformaldehyde exterior layer；Circlip 3 is engineering plastics circlip；The of previous chain link 1
Two 12 faces of second sleeve of one sleeve 11 and latter chain link 1 are simultaneously located between two second sleeves 12, and pin shaft 2 runs through first
It is connect after sleeve 11 and second sleeve 12 with circlip 3.
Based on above-mentioned structure, the chain of the mud scraper of the utility model by wrapping up steel bar 131 in linking arm 13, with
The intensity for increasing linking arm 13, after being enclosed with steel bar 131, so that the intensity of whole linking arm 13 is higher；The main material of its pin shaft 2
Material selects polyformaldehyde, and the axle center that useful glass fibre is made into is arranged, and can greatly increase shock resistance and the tensile capacity of pin shaft 2；
Circlip 3 is made using engineering plastics, and intensity is high, quick detachable and reusable.
In the present embodiment, as shown in Figures 2 and 3, the outer side surface 132 of every linking arm 13 is provided with 3 side by side
The reinforcing rib 133 of the truncated wedge of setting, every reinforcing rib 133 include the first right-angle side 1331, the second right-angle side 1332 and tiltedly
Side 1333.As shown in figure 3, the first right-angle side 1331 for being located in the middle reinforcing rib 133 is connect with outer side surface 132, second is straight
The arm of angle 1332 is connect with first sleeve 11；The first right-angle side 1331 positioned at the reinforcing rib 133 of two sides connects with outer side surface 132
It connects, the second right-angle side 1332 is connect with second sleeve 12, and principle can refer to Fig. 3.It is set by the outer side surface 132 in linking arm 13
Reinforcing rib 133 is set, can be improved the tensile strength of entire chain link 1, the presence of reinforcing rib 133 can make linking arm 13 and first
