Description
Technical field
The utility model relates to a kind of transmission device of standing crop harvest machinery, the transmission device that especially a kind of maize harvesting machine fruit ear is carried.
Background technology
At present, along with researcher's continuous development, maize harvesting machine is increased to 3 or 4 results cell cubes by 2 original results cell cubes.A kind of " backpack stalk-spike-reaping corn full width reaping machine " disclosed in the CN2686299Y China utility model patent specification of for example announcing on March 23rd, 2005, be to comprise 2-4 results cell cube arranged side by side in the disclosure file at the harvesting-platform that hangs on tractor the place ahead, be provided with Apparatus for cutting stalk into pieces hanging on rear tractor, its each results cell cube comprises a pair of acclivitous, axis is parallel, the snapping bar that height interlaces and arranges, fruit ear conveying gathering unit comprises that being located at low snapping bar one side respectively establishes defeated fringe plate, the corresponding tassel-conveying driving plate that is fixed on the tassel-conveying chain of establishing with defeated fringe plate also comprises a fruit ear horizontal conveying slide carriage groove and a vertical hoisting equipment that tilts.Its tassel-conveying chain is to adopt corresponding drive disk assembly and final drive shaft to realize transmission of power respectively.
And include a kind of maize harvesting machines of new structure of 2 results cell cubes, by the applicant patent application is proposed and in the CN2927648Y of on August 1st, 2007 bulletin China utility model patent specification disclosed " Backpack-type maize harvester " disclosed, the structure of its results cell cube is identical with the disclosed results cell cube of aforementioned open file, all be to comprise a pair of acclivitous, axis is parallel, height interlaces to be arranged snapping bar, low snapping bar one side is established defeated fringe plate, the corresponding tassel-conveying driving plate that is fixed on the tassel-conveying chain of establishing with defeated fringe plate.Different is that 2 snapping bars of gathering in the crops cell cubes are symmetrically arranged, and shared one defeated fringe plate and is fixed on the tassel-conveying driving plate on the tassel-conveying chain.During maize harvesting machine work, fruit ear on the maize straw is plucked behind stalk by rotating relatively snapping bar, tassel-conveying driving plate that tassel-conveying chain drives and it is fixing of process running is pulled over fruit ear in the horizontal conveying slide carriage of the fruit ear groove, slip into again in the vertical hoisting equipment, sent into the fruit ear case by vertical hoisting equipment then.There is defeated fringe rotating shaft at the both ends that the running that has a tassel-conveying chain of tassel-conveying driving plate is achieved in that defeated fringe plate body support assemblies respectively, the support sprocket wheel is equipped with in defeated fringe rotating shaft correspondence respectively, tassel-conveying chain is to be assemblied on the sprocket wheel of these two defeated fringe rotating shafts, drive sprocket, the driving chain of power on the driving shaft through being installed on this is delivered on the defeated fringe driven sprocket, and defeated fringe driven sprocket is mounted in the defeated fringe rotating shaft.When the results cell cube of the maize harvesting machine of said structure will be increased to 3 or 4, the defeated fringe plate of needs increase reaches and fails the corresponding quantity that is fixed on the tassel-conveying driving plate on the tassel-conveying chain that is provided with of fringe plate, the kind of drive according to tassel-conveying chain that prior art is given must increase parts such as driving chain and drive sprocket, cause used drive disk assembly many, increased the manufacturing cost of reaping machine; Owing to be subjected to the restriction of final drive shaft installation site, give to install and also make troubles simultaneously.
Summary of the invention
Used drive disk assembly is many in the existing technology, manufacturing cost is high in order to overcome, inconvenient deficiency is installed, and the utility model provides a kind of transmission device of maize harvesting machine tassel-conveying driving plate.This transmission structures is simple, and cost is low, and reliable transmission is easy for installation.
The technical scheme that its technical problem that solves the utility model adopts is: the transmission device that a kind of maize harvesting machine fruit ear is carried, comprise the defeated fringe plate that is separately positioned on low snapping bar one side and and fail the corresponding tassel-conveying driving plate that is fixed on the tassel-conveying chain that is provided with of fringe plate, there is defeated fringe rotating shaft at the plate body both ends of described each defeated fringe plate support assemblies respectively, in the defeated fringe rotating shaft respectively correspondence the support sprocket wheel is housed, described tassel-conveying chain is to be assemblied on the sprocket wheel of these two defeated fringe rotating shafts, one defeated fringe driven sprocket is installed in the one defeated fringe rotating shaft, should realize transmission of power through driving chain and the drive sprocket that is installed on the driving shaft by defeated fringe driven sprocket, it is characterized in that: also comprise a connecting axle, the two ends of this connecting axle adopt universal coupling with spider to connect respectively with between the corresponding adjacent defeated fringe rotating shaft.
Described connecting axle is to be pegged graft by two-semiaxle to form key connecting between the two-semiaxle.
When the results cell cube increases, the utility model only needs to connect by double universal coupling with between connecting axle and the corresponding adjacent defeated fringe rotating shaft, need not increase parts such as driving chain and drive sprocket, can effectively simplify the mechanical realization of maize harvesting machine, used drive disk assembly is few, reduce cost, install and become more simple.Simultaneously, between tassel-conveying driving plate, adopt the connecting axle of the two-semiaxle composition of universal coupling with spider connection and key connecting, can effectively compensate the problem of relative yaw displacement of two power transmission shafts and length variation.
