Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides, for example, in a combine harvester, an endless rotating belt with a protrusion and an idle rail for its lower rotation path, such as by providing a straw removal cutter and a straw removal tying bamboo at the rear of the combine harvester. A first waste straw processing section and a second waste straw processing section are arranged in that order in the conveying direction of the threshing waste straw conveying device consisting of, and between the @11 waste straw processing section and the second waste straw processing section. , a first state in which the waste straw from the waste straw conveying device is supplied to the first waste straw processing section, and a second state in which the waste straw is supplied to the second waste straw processing section (by which the guide cover is switched in a swinging posture and The present invention relates to a structure of a waste straw processing section of a threshing machine, which is provided in a fixed manner and is provided with an auxiliary conveyance device that transports stray straw from the waste straw transport device to the second straw processing section in the second state.

In the above-mentioned device, if the waste straw processing mode is switched from the second state to the first state while the waste straw is being conveyed by the waste straw conveying device, the guide cover will catch the waste straw, and the removed straw will not be caught. The waste straw supplied to the first wandering straw processing section is caught by the waste straw,
There is a problem that has a negative impact on the supply of waste straw, and conventionally,
The switch was made only when waste straw was not being conveyed.

However, for example, when a series of threshing processes involves switching between shredding and tying waste straw midway through the process, the threshing process must be temporarily interrupted, reducing work efficiency. There were drawbacks.

In view of the above points, the present invention makes it possible to efficiently supply waste straw to the second waste straw processing section, and to change the flow from the second state to the first state during the waste straw transport by the waste straw conveying device. It is an object of the present invention to make it possible to avoid adverse effects on the supply of waste straw to a first waste straw processing section due to the caught sand of waste straw, regardless of the switching.

In order to achieve the above object, in the structure of the waste straw processing section of the threshing machine mentioned above, the auxiliary conveyance device is located closer to the second stray straw processing section than the guide cover in the first state. The guide cover is configured to be able to freely change and fix its swinging posture around an axis different from the swinging axis of the guide cover so as to be positioned so as to be able to receive the waste straw from the waste straw conveying device in the second state. an elastically deformable flexible cover that covers a gap on the free end side between the transport cover of the auxiliary transport device and the guide cover; and in the first state, the flexible cover is It is characterized in that the placed waste straw is positioned so as to be pressed by the endless rotating band with projections.

That is, in the second state, the waste straw from the waste straw conveying device is received by the auxiliary conveyance device, the received waste straw is conveyed to the second waste straw processing section for 6 tons, and then When switching from the second state to the first state, between the guide cover and the auxiliary conveyance device (the wandering straw that is being conveyed at the 0 position is placed on the flexible cover, and the discharged straw is pressed against the endless rotating band with projections). This ensures that the action of the endless rotating belt with projections is applied to the waste straw, and the waste straw is conveyed and discharged through the gap to the second waste straw processing section.

Therefore, compared to, for example, a case where the auxiliary conveyance device is provided in a fixed state and the stray straw from the waste straw conveyance device is supplied downstream to the auxiliary conveyance device via an inclined guide, The waste straw can now be reliably supplied to @2 waste straw 5 processing section by the conveying force of the auxiliary conveyance device. Moreover, even if waste straw is caught on the guide cover when switching from the @2 state to the first state,
Since this is caught by the flexible cover, it is possible to suppress the disturbance of the posture of the waste straw due to its catching, and also to quickly discharge the stray straw on the cover to the second waste straw processing section so that it remains on the cover. This can be avoided, and the second state can be switched from the second state to the first state without adversely affecting the transport to the first waste straw processing section after switching due to the waste straw being caught during the transport of the waste straw. It is no longer necessary to interrupt the threshing operation each time a change is made, and work efficiency can now be improved when changing the straw disposal mode in the middle of a series of threshing operations. Furthermore, since the cover is elastically deformable, regardless of the amount of waste straw on the cover, it can be effectively pressed against the endless rotating band with protrusions and removed by being reliably subjected to its action.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.
