Description

[Detailed Description of the Invention] The present invention relates to a combine harvester that is provided with a guide member for receiving and conveying grain culms from a conveying device of a reaping section that can be vertically driven and raised and lowered to a grain supply guide plate of a threshing device.

As a prior art related to this guide member,
The one described in Japanese Patent No. 7932 is known.

In this system, a guide member made of a flexible material is attached in a cantilevered manner to a conveying device on the reaping section side, and its free end side moves on the guide plate of the threshing device as the reaping section moves up and down. , the guiding action of the grain culm is maintained regardless of the vertical displacement, but this has the following drawbacks.

One of them is that there is a natural limit to the length of the flexible guide member in the culm length direction when cantilever-supporting the flexible guide member with the conveying device.
It is not possible to install a large guide member that protrudes from the conveying device and can sufficiently cover the tip side of the conveying shell culm with the child box, or a long support frame must be specially extended to do so. It is.

Another problem is the amount of movement on the free end side as the reaping section moves up and down.In order to prevent the guide member made of a flexible material from coming off the guide plate of the threshing device, The overlap between the guide member and the plate in the conveyance direction must be large, and either the guide member or the plate must be made large.

The present invention has been developed in view of the above circumstances, and aims to provide a guide member that eliminates the above-mentioned conventional drawbacks and can be used extremely effectively.

The present invention takes the following technical measures.

That is, in the combine harvester described at the beginning of the detailed description of the invention, the guide member made of a flexible material is arranged at a position overlapping the conveyance device and the lesson supply guide plate in plan view, and Of the lower end portions of the guide member in the grain culm conveyance direction, the conveyance husk stock base end portion is supported by the conveyance device, and the conveyance husk culm tip end portion is locked with a fixed frame of the machine body; A feature of the present invention is that the guide member is supported in a cantilever manner by the transport device and the fixed frame.

Moreover, with this configuration, even a guide member that largely protrudes from the conveyance device of the reaping section can be supported in a cantilever manner without requiring a special support member.

Moreover, when the reaping section is raised or lowered, the guide member swings around the fixed frame side of the machine body, as shown in Figure 2 of the drawings of the embodiment described later, so the entire guide member moves in the conveying direction. Compared to the conventional example, the guide member is less likely to come off from the grain culm supply guide plate, and the overlapping of the two in the conveyance direction is reduced, resulting in a more compact structure as a whole.

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

A lifting device 1 that pulls up planted grain culms in the field, a reaping device 2 that reaps the raised grain culms, and a feed chain 3 that changes the attitude of the harvested grain culms to a nearly horizontal position while conveying them to the rear of the machine. A reaping section 5 consisting of a conveying device 4 for delivering and delivering, and a threshing device 6 for threshing while conveying the shell culms by a feed chain 3 are equipped with a crawler traveling device 7 and a control section 8.
The combine harvester is connected to a traveling machine equipped with a machine, so that as it travels, it continuously harvests and processes the planted shell culms in the field.

The reaping section 5 is pivotally connected to the traveling machine body so as to be able to swing up and down around the rear transverse axis 4, and the reaping section 5 can be raised and lowered to adjust the cutting height or perform non-working tasks such as crossing ridges. It is designed to ensure safe driving.

A curved guide plate 10 is provided protruding from the lower part of the grain supply port 9 of the threshing device 6, and a guide member 11 is provided extending from the conveyance end of the conveyance device 4 to the guide plate 10. Threshing device 6 that receives the shell culm of the shell
The structure is such that the conveyance is guided.

The guide member 11 is made up of a flexible rectangular cloth material 12 and a piano wire 13, and is attached by sewing the piano wire 13a into one long side of the cloth material 12. At the same time, piano wires 13b are sewn in and attached at a predetermined interval in the longitudinal direction of the cloth material 12 and with one end side pivotally connected to the piano wire 13a, and, One end of the piano wire 13a is pivotally connected to a predetermined location on the rear end of the transport device 4, and the other end is inserted and supported in a predetermined location on the support frame 14 of the control section 8 in a manner movable in three-dimensional directions. As the reaping part 5 moves up and down, the guide member 11 is displaced around the attachment part to the support frame 14, and with this displacement, the long side of the other end is moved by the weight of the receiving grain culm. It is configured to elastically displace while in sliding contact with the guide plate 10, and to maintain a smooth continuous surface in the culm feeding direction by the self-shaping force of the piano wires 13.

In the above embodiment, each of the piano wires 13b is connected to the piano wire 13a via a coil spring, and the free end of the piano wire 13b is in contact with the guide plate 10. It is also possible to apply the force to.

Note that the guide member 11 includes a cloth material 12 and a piano wire 1.
3... Not limited to those based on . Various structural deformations are possible as long as the material can be elastically bent to maintain a state close to that of the material, and can maintain a smooth continuous surface in the direction of transport due to its self-retention force. be.
