Along with the continuous development of agricultural mechanization, agricultural harvesting machinery begins towards maximization, and the direction of a tractor serves several purposesization strides forward.The function of combine is constantly strengthened at present, has improved harvesting efficiency.
In large-scale combined harvester, need be delivered to transport vehicle by grains unloading system to the particle of results.At existing self-propelled grain harvester grains unloading system, comprise two augers that are provided with certain angle, be auger at the bottom of the silo and unloading auger, the screw-conveyer-shaft of two augers connects by a universal joint, be the rotation combination between the two, i.e. two screw-conveyer-shaft engaged transmission in use, two screw-conveyer-shafts break away from when idle.Occur in conjunction with phenomenon not in place through regular meeting in actual use, cause that unloading screw-conveyer-shaft axiality is bad, the grains unloading system instability, fragile.And screw-conveyer-shaft and unloading screw-conveyer-shaft are by a universal joint combination at the bottom of the silo, and the universal joint angle is big, and is fragile.In the universal joint junction of diaxon, grain can not be carried smoothly, and the percentage of damage of seed can raise.
The utility model content
The technical problems to be solved in the utility model provides a kind of rotation often in conjunction with grains unloading system, can effectively solve the rotation that occurs in the existing grains unloading system in conjunction with problem not in place, that the universal joint angle is big, under the prerequisite that guarantees the grain smooth delivery of power, guarantee system safety operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of rotation is often in conjunction with grains unloading system, comprise two augers, be respectively auger at the bottom of unloading auger and the silo, auger horizontal positioned at the bottom of the silo wherein, the unloading auger tilts to place, one side of unloading auger is provided with it parallel relaying power transmission shaft, be connected by driving-chain between the unloading screw-conveyer-shaft of unloading auger and the relaying power transmission shaft, it is characterized in that being connected by universal joint between the screw-conveyer-shaft at the bottom of the silo of described relaying power transmission shaft and auger at the bottom of the silo.
Said structure is described further, and described universal joint is more than two, and series connection successively forms the universal joint group.
Said structure is described further, and an end of described unloading auger is provided with trough of belt unloading bucket, and described trough of belt unloading casing is in the bottom of unloading auger, and trough of belt unloading bucket is communicated with auger at the bottom of the silo.
The beneficial effect that adopts technique scheme to produce is: the utility model is in order to overcome existing self-propelled grain harvester rotation in conjunction with the unloading instability, structure is improved, mainly be on original basis, increased universal joint, and the plural universal joint of connecting, make the bottom of unloading bucket increase the groove of storing grain, grain is carried formed two relatively independent processes, auger pushes away grain and enters trough of belt unloading groove at the bottom of the silo, grain in the trough of belt unloading groove is pushed in the grain car by the unloading screw-conveyer-shaft, structure after the improvement can realize the normal combination of revolute pair, whole grains unloading system is stable, grain energy smooth delivery of power, the while has also been reduced the percentage of damage of grain in course of conveying.

Embodiment
With reference to the accompanying drawings as can be known, the utility model is specifically related to a kind of rotation often in conjunction with grains unloading system, is mainly used in large-scale self-propelled combine grain and carries.
In accompanying drawing 1 as can be seen, concrete structure of the present utility model comprises two augers, be respectively auger at the bottom of unloading auger and the silo, auger horizontal positioned at the bottom of the silo wherein, the unloading auger tilts to place, one side of unloading auger is provided with it parallel relaying power transmission shaft 3, is connected by driving-chain between the unloading screw-conveyer-shaft 4 of unloading auger and the relaying power transmission shaft 3, is connected by universal joint 2 between the screw-conveyer-shaft 1 at the bottom of the silo of relaying power transmission shaft 3 and auger at the bottom of the silo.
In accompanying drawing 2, universal joint 2 is more than two, and series connection successively forms the universal joint group.Be connected between relaying power transmission shaft 3 and the screw-conveyer-shaft at the bottom of the silo 1 by the universal joint group, realize the normal combination of rotation of two auger junctions, can avoid because of often use occur in conjunction with not in place, perhaps serious wear for a long time, cause unloading screw-conveyer-shaft axiality bad, the grains unloading system instability; And screw-conveyer-shaft 1 and unloading screw-conveyer-shaft 4 can be realized unloading screw-conveyer-shaft 4 large angle pendulums by the universal joint group combination of a series connection at the bottom of the silo, have also avoided a seed damage problem that the universal joint junction occurs, and have reduced the percentage of damage of seed.
In accompanying drawing 1 and 3, an end of unloading auger is provided with trough of belt unloading bucket 5, and trough of belt unloading bucket 5 is placed in the bottom of unloading auger, and trough of belt unloading bucket 5 is communicated with auger at the bottom of the silo.Trough of belt unloading bucket 5 bottoms are provided with groove, can store the grain of auger feeding at the bottom of the silo, thereby realize an original grain transportation, be split as two relatively independent fortune beam processes, be that auger pushes away grain and enters trough of belt unloading groove 5 at the bottom of the silo, the grain in the trough of belt unloading groove 5 is pushed in the grain car by the unloading screw-conveyer-shaft, and trough of belt unloading groove 5 becomes lead-over groove in the grain transportation like this, store unnecessary grain, avoided the blockage problem that has some setbacks and produce because of transportation.
The utility model in use by 1 rotation of screw-conveyer-shaft at the bottom of the silo, passes to relaying power transmission shaft 3 to turning moment by universal joint 2, has the driving-chain of relaying power transmission shaft 3 one ends to drive unloading screw-conveyer-shaft 4 at last, realizes the unloading operation of combined harvester.The utility model rotation is often stable in conjunction with grains unloading system, and grain energy smooth delivery of power reduces percentage of damage.
