Description

  The present invention relates to a transmission structure to a threshing device or the like in a combiner in which the threshing type is a self-ejecting type or a normal type and the traveling type is a crawler type or a foil type.

  In the combine equipped with the Glenn tank which stores the grain collected by the threshing device, and the discharge screw which discharges the grain stored in the Glen tank, for example, as disclosed in Patent Document 1, Some are configured to transmit power to the threshing device and the discharge screw in parallel.

In Patent Document 1, the power of the engine output shaft is transmitted to the threshing device via a transmission belt (corresponding to a threshing transmission system), and the power of the engine output shaft is discharged via a transmission belt (corresponding to a work transmission system). It is transmitted to the screw.
The transmission belt to the threshing device and the transmission belt to the discharge clutch have a clutch function (corresponding to the threshing clutch and the working clutch), and the transmission belt clutch to the threshing device and the transmission belt to the discharge clutch by an electric motor This clutch is configured to be operated in a transmission state and a disengagement state.
Thus, the driver can easily operate the threshing clutch and the work clutch in the transmission state and the cutoff state by the electric motor only by operating the switch or the like.

JP 2012-90607 A (see FIGS. 3 and 9)

In the combine, the positions of the engine, the threshing device, and the glen tank are determined, and therefore, the position of the transmission belt that spans the output shaft of the engine, the threshing device, and the discharge screw is also determined.
Thereby, for example, when making a design change such as a change in the arrangement of the frame or a change in the arrangement of another device, the position of the transmission belt across the output shaft of the engine, the threshing device and the discharge screw is determined as described above. If this is the case, this transmission belt may be an obstacle to the above-described design change. Further, there is a growing demand for improved fuel efficiency from the viewpoints of resource saving and environmental protection.

  In the combine, the present invention is configured so that the driver can easily operate the threshing clutch and the working clutch in the transmission state and the disconnection state, and can be adapted to the design change in the vicinity of the driving unit, The purpose is to be able to improve.

(Constitution)
The present invention is to configure the combine as follows.
A threshing device, and a working device separate from the threshing device,
The upper transmission system to which the power of the prime mover is transmitted is branched into a threshing transmission system connected to the threshing device and a work transmission system connected to the working device, and the power of the prime mover is It is configured to be transmitted to the threshing device and the working device via a side transmission system, the threshing transmission system and the work transmission system,
An upper clutch is provided in the upper transmission system, a threshing clutch is provided in the threshing transmission system, and a working clutch is provided in the working transmission system,
An operating device is provided for operating the upper clutch, the threshing clutch, and the work clutch in a transmission state and a cutoff state.

(Operation and effect of the invention)
According to the present invention, the power of the prime mover is not directly transmitted to the threshing device and the work device via the threshing transmission system and the work transmission system as in Patent Document 1, but the power of the prime mover is transmitted to the upper side transmission system. It is comprised so that it may branch to a threshing transmission system and a work transmission system from a good side transmission system.
In this case, it is relatively easy to change the position of the upper transmission system compared to the driving part, so it is difficult to change the position of the threshing transmission system and the working transmission system when making a design change in the vicinity of the driving part. Even so, the design change in the vicinity of the prime mover can be made relatively easily by changing the position of the upper transmission system so as to adapt to the design change in the vicinity of the prime mover.

As described above, when the power of the prime mover is transmitted to the upper power transmission system and is transmitted from the upper power transmission system to the threshing device and the work device via the threshing transmission system and the work transmission system, Since the transmission system from the threshing device to the working device becomes longer by the upper transmission system, the following points may be disadvantageous in terms of fuel consumption.
For example, even if the threshing clutch and the working clutch are operated in the disconnected state to stop the threshing device and the working device, the power of the driving unit is transmitted to the upper transmission system (the transmission shaft of the upper transmission system is rotationally driven). As a result, the power of the prime mover is consumed by the power of the upper transmission system.

  On the other hand, according to the present invention, when the threshing clutch and the working clutch are operated in the disengaged state to stop the threshing device and the working device, the upper clutch is also operated in the disengaged state. Therefore, it is possible to reduce the state in which the power of the driving part is consumed excessively, and to improve the fuel consumption.

(Constitution)
The present invention is preferably configured as follows.
The operation device is provided with a neutral position where the upper clutch, the threshing clutch, and the work clutch are operated in a disconnected state.

When the operating device is operated from the neutral position, the operating device is configured such that the upper clutch is first operated in the transmission state.

(Operation and effect of the invention)
According to the present invention, when the operating device is operated from the neutral position, the threshing clutch (working clutch) is not operated in the transmission state before the upper clutch.
Thereby, after the threshing clutch (working clutch) is operated in the transmission state, the upper clutch is operated in the transmission state, whereby the power of the driving unit is suddenly transmitted to the threshing device (working device) and a shock is generated. The state of occurrence can be suppressed.
