Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a disassembling structure of a threshing device.

[Conventional technology]

Considering the combine threshing device, the combine threshing device is provided with a rocking case for selecting the processed products from the handling room, and conventionally, this rocking case is configured to be pulled out from the outer wall of the threshing device. There are also some (without reference citations).

[Problems to be solved by the device]

Further, in recent threshing devices, a chaff sheave provided in the rocking case in order to adjust the selection performance in accordance with the amount of grain culms to be supplied, or the moisture contained in the grain culms,
A structure is being developed in which the leaking area of the Glensieve or the like is configured to be operated from the outside of the rocking case.

However, in the threshing device configured such that the sorting performance of the swinging case can be performed by an operation from the outside of the swinging case, the swinging case is removed when the swinging case is pulled out from the outer wall of the threshing device as described above. It is necessary to separate the operating system for adjusting the sorting performance of the case.For example, in the case where this operating system is composed of wires, it takes time and effort to disconnect the inner wire and the outer wire, respectively. It becomes annoying.

An object of the present invention is to rationally configure a structure in which the rocking case connected to an operation system for adjusting the sorting performance can be pulled out from the outer wall of the threshing device as easily as possible.

[Means for Solving the Problems]

The feature of the present invention is that a mechanism for adjusting the individual performance by changing the posture of the member is provided for the swing case configured to be able to be pulled out from the outer wall of the threshing device, and the posture of this member can be adjusted by changing the wire. The control device operated via the control unit is detachably provided on the outer wall of the threshing device, and the electric wiring for the control device is provided with a connector for separation. Is.

[Action]

If the above features are configured as shown in FIG. 1, for example, when the rocking case (4) is pulled out from the outer wall (23) of the threshing device,
By removing the control device (B) from the outer wall (23) of the threshing device, and simply by separating the connector (34),
Control device via wire (22) to rocking case (4)
With (B) working together, each can be pulled out from the threshing device.

[Effect of device]

Therefore, the process of separating the inner wire and the outer wire from each other by using tools such as a wrench which is usually required is eliminated, so that the rocking case linked to the operation system for adjusting the sorting performance is removed from the threshing device. The structure was so constructed that it would be easy to take it out from the outer wall of the.

In particular, in the present invention, since the wires are not separated, the adjustment amount of the sorting performance with respect to the operation of the control device is not different from that of the case where the wires are separated. There is also an effect that it is not necessary to adjust the operation amount of.
