Abstract
The utility model discloses a combined harvester gap bridge which comprises a gap bridge shell body, a gap bridge driving shaft and a gap bridge driven shaft. Driving chain wheels are installed on the gap bridge driving shaft, driven chain wheels paired with the driving chain wheels are installed on the gap bridge driven shaft, a conveying chain is installed on each pair of driving chain wheel and driven chain wheel, chain harrows are installed on the conveying chains, the number of the driving chain wheels and the number of the driven chain wheels are respectively at least three, the number of the conveying chains is at least three, and the chain harrows are installed on the two adjacent conveying chains in a crossed mode. Compared with the prior art, the combined harvester gap bridge has the advantages that the number of the driving chain wheels and the number of the driven chain wheels are increased on the gap bridge, namely, the number of the conveying chains is increased, the chain harrows are shortened, the densities of the chain harrows are bigger, when crops are conveyed, the stress of the chain harrows is more reasonable and evener (a resisting arm is reduced), the chain harrows and the conveying chains are not easily damaged, the conveying reliability of the gap bridge is higher, the service life of the chain harrows and the service life of the conveying chains are greatly prolonged, the maintenance cost is reduced, and the operation efficiency of a machine driver is improved.
Description
Technical field
The utility model relates to agricultural machinery, and specifically, the utility model relates to a kind of combine and passes a bridge.
Background technology
At present, combine gap bridge structure for conveying comprises gap bridge driving shaft and gap bridge driven axle, two drive sprockets and two are being contained on two axles respectively by movable sprocket, article two, chain is contained in respectively corresponding drive sprocket and by movable sprocket, two chain respective link are equipped with chain harrow, along with the rotation of drive sprocket, chain harrow is delivered to sheller unit by the crop of harvesting from crossing pars basilaris pontis, as shown in Figure 3 and Figure 4.
Along with the increasing of grain header feed quantity, carry load constantly to increase; Grain header gap bridge width is also in continuous increase, and the distance of two groups of chains also constantly increases.The above two reasons structure for conveying stressed effect variation (resistance arm lengthening) that causes passing a bridge, chain harrow and chain are fragile, cause maintenance cost to improve, and affect tractor driver's operating efficiency.
The novel problem to be solved of this use is to provide the Overbridge device that a kind of three groups of chains are carried, and improves the reliability of passing a bridge and carrying.
The utility model content
Technical problem to be solved in the utility model is that a kind of combine with high reliability is passed a bridge.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of combine is passed a bridge, comprise the gap bridge housing, gap bridge driving shaft and gap bridge driven axle, on the gap bridge driving shaft, drive sprocket is installed, with drive sprocket paired by movable sprocket, be arranged on the gap bridge driven axle, at every pair of drive sprocket with on by movable sprocket, chain is installed, chain harrow is installed on chain, described drive sprocket and describedly all be provided with at least three by movable sprocket, described chain is provided with three at least, described chain harrow is across being arranged on two adjacent chains.
Described drive sprocket and describedly be provided with three by movable sprocket, described chain is provided with three.
What described chain harrow was staggered is arranged on three chains.
The utility model adopts technique scheme, compared with prior art, on gap bridge, increase drive sprocket and, by the number of movable sprocket, namely increased the radical of chain, chain harrow shortens, the density of chain harrow is larger, chain harrow more reasonable stress even (resistance arm reduces) when carrying crop, and chain harrow and chain are not fragile, the conveying reliability of passing a bridge is higher, greatly extend the service life of chain harrow and chain, reduced maintenance cost, and improve tractor driver's operating efficiency.
The accompanying drawing explanation

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of the gap bridge in background technology;
Fig. 4 is the vertical view of Fig. 3;
Mark in above-mentioned figure is: 1, gap bridge housing; 2, gap bridge driven axle; 3, by movable sprocket; 4, chain; 5, chain harrow; 6, drive sprocket; 7, gap bridge driving shaft.
Embodiment
Be that a kind of combine of the present utility model is passed a bridge as depicted in figs. 1 and 2, it comprises gap bridge housing 1, gap bridge driving shaft 7 and gap bridge driven axle 2, drive sprocket 6 is installed on gap bridge driving shaft 7, with drive sprocket 6 paired by movable sprocket 3, be arranged on gap bridge driven axle 2, at every pair of drive sprocket 6 with on by movable sprocket 3, chain 4 is installed, chain harrow 5 is installed on chain 4.On the conveying reliability that improves gap bridge, drive sprocket 6 and all be provided with at least three by movable sprocket 3, corresponding chain 4 is provided with three at least, and chain harrow 5 is across being arranged on two adjacent chains 4.Compared with prior art, on gap bridge, increase drive sprocket 6 and by the number of movable sprocket 3, namely increased the radical of chain 4, chain harrow 5 shortens, and the density of chain harrow 5 is larger, chain harrow 5 more reasonable stress even (resistance arm reduces) when carrying crop, chain harrow 5 and chain 4 are not fragile, and the conveying reliability of gap bridge is higher, and greatly extend the service life of chain harrow 5 and chain 4, reduce maintenance cost, and improved tractor driver's operating efficiency.
As shown in Figure 2, in the present embodiment, drive sprocket 6 and be provided with three by movable sprocket 3, chain 4 is provided with three, and each chain harrow 5 is across being arranged on two adjacent chains 4, and chain harrow 5 is staggered one by one layout on three chains 4.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out as long as adopted; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
