Description
Technical field
The present invention relates to a kind of chain for agricultural harvester and chain fittings thereof.
Background technique
In the rural area that China is vast, root crop harvester starts to apply widely.Conveying means on cropper in the market mainly divides two kinds, and one is rubber type crawler belt 1, and by fastening piece 3 fixed thereon for beaming roller 2, its structure is see Fig. 1-2; Two is bent plate chain, and beaming roller 5 is penetrated annex 6 with holes, then by fastening piece 4, annex 6 is fixed on bent plate 7, and its structure is see Fig. 3-4.
The shortcoming that this two kinds of conveying meanss have some relatively to give prominence to:
1) rubber type crawler belt cost is higher;
2) the rubber type crawler belt life-span is short, once there be damage, and necessary integral replacing;
3) bent plate chain type, bending plate Impact direction is vertical with carrier bar, and shock-resistant ability is poor, easily ruptures during use;
4) bent plate chain type, having earth dust to enter in chain link during use can cause chain wear, reduces working life;
5) two kinds of devices all cannot install the larger beaming roller of diameter, and thin beaming roller is not wear-resisting, flexible damage when receiving impact;
6) beaming roller of two kinds of devices connects by single fastening piece completely, and poor stability, in use easily comes off;

A kind of chain fittings for agricultural harvester, comprise multiple link units, each link units includes the first chain link and the second chain link, wherein, first chain link comprises two the first connection carrier bars be arranged side by side, second chain link comprises two the second connection carrier bars be arranged side by side, from second connect that carrier bar extends for connecting the beaming roller joint of beaming roller and connecting the fixed plate of two beaming roller joints, second chain link is U-shaped structure, second connects carrier bar, fixed plate and beaming roller joint are integral type linkage structure, the first adjacent connection carrier bar and second is connected carrier bar and passes through pinned connection, beaming roller joint offers beaming roller attachment hole, the straight line of center of circle formation of two beaming roller attachment holes in each second chain link and the axis being parallel of bearing pin.
As preferably, the straight line that each second center of circle connecting two bearing pin mounting holes on carrier bar is formed is vertical with fixed plate, and the distance of center circle of beaming roller attachment hole is equal from the length in the center of circle of two bearing pin mounting holes.
As preferably, described first chain link is inner link, and the second chain link is outer link.
As preferably, chain fittings adopts loose type assembling, i.e. adopt larger Spielpassung between the component of chain.
The present invention compared with prior art, has the following advantages and effect:
1) adopt chain link plate, be convenient for changing;
2) adopt the second chain link of U-shaped structure, during use, Impact direction is parallel with the fixed plate on the second chain link, shock-resistant, strengthens working life;
3) chain strip adoption loose type assembling mode, namely adopts larger Spielpassung.Earth dust enters conveying means, can drop out from gap, little on chain wear impact;
4) the beaming roller attachment hole on the second chain link of U-shaped structure can install the larger beaming roller of diameter, wear and shock-resistant more, strengthens working life;
5) beaming roller is fixedly changed into by annex and directly being fixed by carrier bar, then from the Vertical direction auxiliary locking of set screw nut, difficult drop-off, greatly strengthen firm intensity;
6) fastening piece of Vertical direction, i.e. set screw nut, lower than edge on fixed plate, does not directly contact earth during use, effectively protects fastening piece, strengthens working life.
