Description

[Detailed description of the invention] The present invention is provided with a feeder that is equipped with a reaping device and forms a supply path for the reaping section to the handling chamber, and is installed so as to be able to swing up and down with its terminal end entering the handling chamber. The present invention relates to a structure of a feeder attachment part in a harvester, in which a bottom plate for guiding harvested material onto a concave extends downwardly from the concave to be vertically swingable.

Conventionally, in the above harvesting machine, as shown in FIG. 4, even when the feeder 4 is swing-adjusted to adjust the cutting height, the guide bottom plate 24 is securely in contact with the feeder 4, and the feeder insertion portion is In order to ensure that the gap S between the member 26 forming the peripheral wall and the guide bottom plate 24 is closed, the guide bottom plate 24
This is because a spring 32 is provided for pressing the feeder 4, and a member 27 for closing the gap S is provided so as to be in constant contact with the guide bottom plate 24 regardless of the displacement of the guide bottom plate 24. However, the structure is complicated, as both a structure for press-contacting and urging the guide bottom plate and a structure for closing the gap are required.

An object of the present invention is to provide a device with a simple structure that can reliably bring the guide bottom plate into contact with the feeder and reliably close the gap regardless of the swing adjustment of the feeder.

The characteristic structure of the present invention is that, in the structure of the feeder attachment part of the harvester mentioned above, the closing member for the gap between the member forming the peripheral wall of the feeder insertion part and the guide bottom plate is pressed against the back surface of the guide bottom plate. The functions and effects are as follows.

In other words, the gap closing member acts to push up the guide bottom plate so that the guide bottom plate is always in contact with the feeder regardless of the swinging of the feeder, and the gap closing member is always in contact with the guide bottom plate even if the guide bottom plate is oscillated. Follow-up displacement to make contact.

Therefore, it is possible to always keep the guide bottom plate in contact with the feeder regardless of the swinging displacement of the feeder, and to always close the gap between the guide bottom plate and the peripheral wall forming member, as in the past. The structure has a simple structure that can be used both as a structure for pressure contact with the concave and as a gap closing structure, and that can reliably supply harvested material to the concave and prevent material to be processed in the machine from spilling out from the gap regardless of cutting height adjustment. I was able to obtain it.

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

As shown in Fig. 1, a rotary reel 1 that pulls up the planted grain culm and scrapes it toward the rear of the machine, a reaping device 2 for the planted grain culm, and a conveyor 3 that transfers the harvested grain culm to the rear of the machine are attached to the feeder 4. In addition, a reaping pre-processing device A configured to transport the entire reaped grain culm from the conveyor 3 to the rear of the machine by a rotating body 6 and a conveyor 7 along a supply path 5 formed by a feeder 4, A vertical swing operation by a cylinder 9 is freely connected to the front part of the crawler type traveling body having a driving part 8 so as to adjust the cutting height. Furthermore, a handling cylinder 11 rotates the harvested grain culm supplied from the feeder 4 to the handling chamber 10.
and a concave 12 for handling and processing, a swinging sorting plate 13 for the processed material falling from the concave 12, a sorting plate 15 for the processed material supplied from the threshing section by the rotating body 14, and both of these sorting plates 1.
A wind sorting section has a sorting plate 16 for the processed materials from 3 and 15 and a winnower 17 that supplies sorting air, and threshed grains are supplied from this sorting section by a screw conveyor 18 and a grain lifting device 19. A combine harvester is constructed by equipping the traveling machine with a storage tank 20 for the second process, a screw conveyor 21 for returning the second processed material from the sorting section to the handling chamber 10, and a lifting device 22.

To connect the pretreatment device A, as shown in FIG. 2 and FIG.
3, it is mounted so that it can swing vertically around the axis _P1 .
Then, the bottom plate 24 that guides the grain from the feeder 4 onto the concave 12 is attached to the concave 12.
A pair of left and right lateral side plates 25a, 25b and a lateral frame 26 extend downward from the feeder 4 so as to be able to swing up and down about the axis _P2 , and form the neck wall of the feeder insertion portion. The closing plate 27 for the gap S between the horizontal frame 26 and the guide bottom plate 24 is moved from the horizontal frame 26 to the horizontal axis center.
It extends around P ₃ so that it can swing back and forth. and,
The guide bottom plate 24 is arranged so that even if the feeder 4 is oscillated, the guide bottom plate 24 is moved so that it comes into contact with the feeder 4, and so that the closing plate 27 is moved so that it comes into contact with the guide bottom plate 24. A spring 28 is attached to the closing plate 27, which presses against the feeder 4 via the closing plate 27 and urges the closing plate 27 against the back surface of the guide bottom plate 24.
Regardless of the swinging of the feeder 4, the grain culms from the feeder 4 do not fall out from between the feeder 4 and the concave 12, and the grain culms flow through the concave 1.
2, so that the guide bottom plate 24 is always firmly in pressure contact with the feeder 4.
In addition, the gap S is always reliably closed so that the processed material in the threshing section and the sorting section does not spill out of the machine.

Note that the elastic plate 29 shown in FIG.
This is to close the gap between the upper edge of the feeder insertion port formed in the feeder 4 and the upper edge of the feeder 4.
Further, the curved portion 27a and the sealing material 30 provided on the closing plate 27 are used to cover the connecting hinge between the closing plate 27 and the frame 26, and to prevent dust from leaking out from the hinge. This is for sealing between the end and the frame 26. Furthermore, the stopper 31 shown in FIG. 2 defines the swing limits of the guide bottom plate 24 and the closing plate 27.

The closing plate 27 has been changed to a telescopic structure in which it is urged to extend so as to be in constant contact with the guide bottom plate 24, or a structure in which it is slidably attached to the frame 26 and is urged to protrude so as to be in constant contact with the guide bottom plate 24. possible, and these are collectively referred to as the closing member 27.
