Abstract

PURPOSE:To simplify power transmission structure and to make a belt play a role of safeguard in the case of locking caused by clogging of treating barrel by driving the treating barrel through a counter shaft by a handling barrel, working a chain inside treating chamber and operating a belt outside the handling chamber. CONSTITUTION:A counter shaft 25 to drive a treating barrel is supported on a shaft 14 between a reinforcing member 23 and a middle plate 8. A transmission belt 28 is wound on between a pulley 26 attached to one end of the counter shaft 25 and a pulley 27 fixed to a handling barrel shaft 1 A, a transmission chain 31 is hung on between a sprocket 29 fixed to the other end of the counter shaft 25 and a sprocket 30 attached to a treating barrel shaft 14A and the treating barrel 14 is revolved and driven by the handling barrel 1 to constitute linking. Consequently, power transmission structure between the handling barrel 1 and the treating barrel 14 is simplified and can be arranged at the side of outlet of the handling chamber 2. Further, even if the power transmission structure is locked due to clogging in the treating barrel, the belt side plays a role of safeguard. A belt is simply changed when the belt is damaged and the power transmission device has excellent maintenance.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized in that the handling cylinder and the processing cylinder are parallel to each other, and the processing cylinder is located behind the corresponding part of the dust inlet provided at the end of the handling chamber. The present invention relates to a power transmission device in a double-acting deaerator having an extended structure.

[Prior art]

In the conventional power transmission device for this grain threshing machine, the transmission mechanism for both the handling cylinder and the processing cylinder had to be arranged centrally on the axially inlet side of the handling cylinder. In other words, in order to drive the processing cylinder by winding a belt directly between both shafts as a means of driving the processing cylinder, the processing cylinder shaft must extend forward to the entrance side of the processing chamber, and the processing cylinder must Coupled with the fact that a transmission mechanism is interposed in the transmission mechanism and the transmission mechanism to this handling barrel, the space occupied by the entire transmission mechanism on the handling chamber entrance side becomes unreasonably large, making it difficult to install it on a combine harvester in terms of layout. There was a problem that resulted in an unfavorable configuration.

(To be solved by the invention [Jl]) In view of this point, the present invention provides a counter shaft between the handling cylinder and the processing cylinder, and drives the handling cylinder to the processing cylinder via this counter shaft. Accordingly, the transmission mechanism for the processing cylinder is disposed on the exit side of the processing chamber in an attempt to solve the conventional problems.

Moreover, although it is a rational power transmission structure, it does not attempt to improve maintenance by changing the transmission belt or the like.

Therefore, the present invention has taken the following technical measures.

[Means to solve the problem]

That is, the technical means according to the present invention is such that a part of the handling chamber 2 corresponding to the dust inlet 5 opened at the terminal end in the axial direction of the handling barrel 1 is extended to the rear side of the machine parallel to the handling barrel axis. RAl1M1
4 is extended and rotatably mounted on the shaft, and the handling cylinder 1 and the processing JI
A counter shaft 25 is provided between and parallel to the processing IJ114, and the winding from the handling till to the counter shaft 25 is rotationally driven by a transmission belt 28, and the winding from the counter shaft 25 to the processing IJ114 is driven by a transmission chain 31. It is characterized by a rotationally driven mechanism (interlocking structure).

[Effects of the Invention] Therefore, according to the present invention, the handling cylinder is driven from the processing cylinder through the counter shaft, and the winding is driven by a transmission belt and the winding is driven by a transmission chain. Although the power transmission mechanism in the above arrangement of the handling cylinder and the processing cylinder is simple, the transmission mechanism to the processing cylinder can be placed on the exit side of the handling room, unlike the conventional arrangement on the entrance side of the handling room. We have now been able to resolve the problems that were concentrated in the Furthermore, since the chain can be driven inside the handling chamber and the belt can be driven outside the handling chamber, even if the processing cylinder locks up due to overload due to clogging, the belt side can act as a safety device. , in case the belt is damaged.

Because it is outside the handling room, belt replacement is easy and maintenance is easy.
