Abstract
The utility model relates to a power transmission structure for a combine harvester, in particular to a power transmission mechanism for tangential-longitudinal-axial threshing cylinders of a full-feed combine harvester. The power transmission mechanism comprises a transverse threshing cylinder, a bevel gear transmission case and a longitudinal threshing cylinder, wherein the power input and output ends of the transverse threshing cylinder are arranged on the two sides of the transverse threshing cylinder respectively; the output end of the transverse threshing cylinder is connected with a first transmission combination sleeve which is connected with the input end of the bevel gear transmission case; the output end of the bevel gear transmission case is connected with one end of a second transmission combination sleeve of which the other end is connected with one end of a transmission shaft; and the other end of the transmission shaft is connected with a transmission part which is connected with the power input end of the longitudinal threshing cylinder. A single-sided power transmission mode is replaced by a double-sided transmission mode, and the transmission shaft and a transmission combination sleeve are matched with the bevel gear transmission case to finish long-distance chain transmission between the transverse threshing cylinder and the longitudinal threshing cylinder, so that transmission stability is improved, and the noise of the harvester is reduced.
Description
Technical field
The utility model relates to the motive power of combine harvester drive mechanism, and specifically a kind of all feeding-in combine is cut vertical flow pattern threshing cylinder power transmission mechanism.
Background technology
Existing all feeding-in combine is cut vertical flow pattern threshing cylinder power transmission mechanism; generally adopt the one-sided chain kind of drive; its transmission mechanism; by engine power is passed to the thresher left side by a power transmission shaft; be passed to horizontal threshing cylinder by the chain transmission again; give the vertical bevel gear housing on the left back limit of threshing cylinder of putting by composite sprocket with transmission of power simultaneously, give vertical put threshing cylinder by the chain transmission with transmission of power by transmission case again.In whole transmission mechanism, except the bevel gear housing that is used for the change transmission direction, all adopt the chain kinds of drive.Because it is larger with horizontal cylinder power intake distance that grain header vertical put the threshing cylinder power input, so chain is longer, thereby bring relative wear soon, the problem of poor reliability.Because chain is longer, on-stream chain can seriously tremble, and produces larger noise simultaneously, and running stability is relatively poor; Secondly because impact distant and structure in the chain a plurality of idlers and regulating wheel must be arranged, thereby overall structure is with regard to aobvious more complicated.
Summary of the invention
For the problems referred to above, the utility model provides a kind of all feeding-in combine to cut vertical flow pattern threshing cylinder power transmission mechanism, and this mechanism is when simplifying existing drive mechanism, improve the stationarity of transmission, reduce vibration, reduce noise, reliability that can Effective Raise work.
According to the technical solution of the utility model: a kind of all feeding-in combine is cut vertical flow pattern threshing cylinder power transmission mechanism, comprise horizontal threshing cylinder, bevel gear housing, the vertical threshing cylinder of putting, it is characterized in that: the power intake of described horizontal threshing cylinder and the output horizontal threshing cylinder both sides of living apart, output connects the first transmission combined cover, described the first transmission combined cover connects the input of bevel gear housing, the output of described bevel gear housing is connected with an end of the second transmission combined cover, the other end of described the second transmission combined cover is connected with power transmission shaft one end, the other end connection for transmission spare of described power transmission shaft, described driving member connect the vertical power intake of putting threshing cylinder.
Described driving member is the V-belt.
Described driving member is chain.
Technique effect of the present utility model is: (1) changes system into the both sides kind of drive with one-sided power transmission mode, optimizes drive mechanism.(2) with in the prior art, horizontal threshing cylinder and vertical put remote chain transmission between threshing cylinder is finished with a power transmission shaft and bevel gear housing of a transmission clutch collar cooperation, not only improves transmission stability, reduce the noise of machine, and improve functional reliability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Among Fig. 1, comprise horizontal threshing cylinder 1, the first transmission combined cover 2, bevel gear housing 3, the second transmission combined cover 4, power transmission shaft 5, vertical threshing cylinder 6, the driving member 7 etc. put.
As shown in Figure 1, the utility model is that a kind of all feeding-in combine is cut vertical flow pattern threshing cylinder power transmission mechanism, comprises horizontal threshing cylinder 1, bevel gear housing 3, the vertical threshing cylinder 6 etc. of putting.The power intake of horizontal threshing cylinder 1 and output horizontal threshing cylinder 1 both sides of living apart, output connects the first transmission combined cover 2, described the first transmission combined cover 2 connects the input of bevel gear housing 3, the output of described bevel gear housing 3 is connected with an end of the second transmission combined cover 4, the other end of described the second transmission combined cover 4 is connected with power transmission shaft 5 one ends, the other end connection for transmission spare 7 of described power transmission shaft 5, described driving member 7 connects the vertical power intake of putting threshing cylinder 6.
Described driving member is the V-belt.
Described driving member is chain.
The course of work of the present utility model is as follows: engine passes to horizontal threshing cylinder 1 with power from horizontal threshing cylinder 1 left side, horizontal threshing cylinder 1 from the right by the first transmission combined cover 2 with transmission of power to bevel gear housing 3, bevel gear housing 3 is passed to power transmission shaft 5 to power by transmission the second clutch collar 4, gives vertical put threshing cylinder 6 by driving member 7 with transmission of power by power transmission shaft 5 at last.
In the transmittance process of whole power, at first will grow, remote complicated chain transmission only replaces with a power transmission shaft; Secondly the monolateral kind of drive of power is divided into the both sides transmission; Thereby effectively reduced vibrations and noise, improved smoothness of operation, and functional reliability.
