Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a storage structure for an auxiliary floor in a combine, which has an auxiliary floor on a paddy receiving floor.

[Problems to be Solved by Prior Art and Invention] Generally, in this kind of combine, a floor-expanding posture is provided on a paddy receiving floor portion provided on one side portion of the airframe so as to protrude toward the outside of the airframe to extend the floor area. , Some have an auxiliary floor that can be rotated and transformed into a storage posture that stands upright along the side of the machine body, but it is proposed to extend the auxiliary floor further forward to secure a wide working space. Has been done. However, when the auxiliary floor is extended forward as described above, the extended portion overlaps the body side cover, so that the extended portion interferes with the body side cover when the auxiliary floor is stored. The auxiliary floor is housed in a state of being projected outward from the side cover of the machine body, and there is a disadvantage that the machine body width is widened in the rear part of the machine body by the protruding amount. In other words, while running on the road, there is a risk that the protruding auxiliary floor will hit people and buildings, while running the harvesting work, the uncut mowing is also done on the paddy receiving floor side of the machine like splitting work. When there is a culm, there is a problem that the uncut culm catches on the auxiliary floor protruding and the culm is broken, the grain is shattered, or the grain is pulled out from the field.

[Means for Solving the Problem] The present invention was conceived with the object of providing a storage structure for an auxiliary floor in a combine that can eliminate these drawbacks in view of the above circumstances. On the paddy receiving floor part provided on one side of the machine body, the floor-extending posture that projects to the outside of the machine body to expand the floor area, and the storage posture that stands up and extends along the side surface of the machine body In a combine that has a floor,
At the front end of the auxiliary floor, an extension portion that extends forward of the front end position of the paddy receiving floor portion and overlaps the airframe side cover is formed, and at the bottom of the extension portion overlapping portion of the airframe side cover, It is characterized in that a storage recess is formed so that the extension can be stored inward of the body side cover while avoiding the interference of the extension with the body side cover in the floor storage posture.

With this configuration, the present invention extends the auxiliary floor by extending the auxiliary floor in the front direction, but allows the auxiliary floor to be stored without protruding from the side cover of the machine body, so that the auxiliary floor can be stored while traveling on the road. It is possible to remarkably improve the running property and to surely eliminate the inconvenience that the stalks are caught on the auxiliary floor during the dividing work or the like.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a combine traveling machine body, and a pre-processing section 2 for cutting off stalks is arranged at the front part of the traveling machine body. Then, the stem culms cut by the pretreatment unit 2 are threshed by the threshing unit 3 arranged on the left side of the machine body, and the untreated foods unloaded here are sorted and then In the paddy receiving portion 4 arranged on the right side of the machine body, it is accommodated in a grain bag (not shown), and the configuration of each of these is conventional. Further, 5 is a driver's seat arranged in front of the paddy receiving part 4, and 6 is a post-processing part such as a cutter arranged in the rear part of the machine body.

A floor 7 is provided in the paddy receiving portion 4, and an outer edge of the floor 7 has a floor-expanded posture in which the floor area is expanded by forming a substantially flush surface with the floor 7 and standing on the side surface of the machine body. Auxiliary floor 8 that can be rotated and transformed to the storage posture along
Are provided via a support shaft 8a. Further, the front end portion of the auxiliary floor 8 is formed with an extended portion that extends forward of the front end position of the floor 7 and overlaps with a side surface cover 10 to be described later. It is designed so that it can be extended to the lower part of the seat 5. An inclined surface is formed on the outer edge of the front end portion of the auxiliary floor 8 so that the auxiliary floor 8 becomes narrower toward the front side.

On the other hand, a step portion 9 is formed on the lower front surface of the driver's seat 5, and a body side cover 10 is provided on an outer edge portion of the step portion 9 to form a cover of the pedal device 9a. is doing. The side cover 10 is formed so as to be substantially flush with the driver's seat cover 11 provided on the side of the driver's seat 5, but at the rear end of the side cover 10, that is, the extension of the auxiliary floor 8. At the lower part of the overlapping portion, it is possible to avoid interference with the extension portion of the auxiliary floor 8 when storing the auxiliary floor 8 and to store the extension portion of the auxiliary floor 8 inward of the side cover 10. Storage recess 1
0a is formed. When the extended portion of the auxiliary floor 8 is stored in the storage recess 10a, the auxiliary floor 8 as a whole is located inward of the side cover 10. And an imaginary line L connecting the outer edge of the side cover 10 and the side cover 10 (the imaginary line L is a line that substantially follows the culm posture of the uncut side stem culm at the outer edge portion of the running body divided by the divider 13) It is located at the same or more inward position so as not to interfere with uncut stems.

By the way, the storage recess 10a is formed in an inclined shape so that it becomes higher toward the rear side, and when the auxiliary floor 8 is stored, a predetermined interval exists on the inclined surface formed on the outer edge of the front end portion of the auxiliary floor 8. It follows that.

Further, in the present embodiment, the cylinder cover 14 of the threshing unit 3 is as follows. That is, although the feed chain 16 is mounted on the cylinder cover 14 that covers the upper side of the handling cylinder 15, the handle 1 is attached to the outer surface of the feed chain 16.
7 is integrally provided, which allows the one conventionally provided on the outer edge portion of the cylinder cover 14 to be set to a lower position, so that the cylinder cover 14 can be opened / closed (especially from the fully closed state). ) Is designed so that even a person with a short provisional authority can easily carry out. Further, links 18 are provided on both front and rear lower surfaces of the cylinder cover 14, and the links 18 are provided for convenience of three sets of plate members 18a to 18c.
Are connected in series, and one end is connected to the cylinder cover 14 and the other end is connected to the upper portions 3a of the front and rear side plates of the threshing unit 3. In the fully closed state, as shown in FIG.
Although b and 18c are in a state of being folded in a polymer form,
When the cylinder cover 14 is lifted by holding the handle 17 to bring it into a half-opened state (FIG. 7A), the plate bodies 18b, 18
Locking body 3 in which pivot pin 18d with c is provided on side plate upper surface 3a
It is adapted to be held in the half open state by being locked to b. Further, when the cylinder cover 14 is lifted to be in the fully opened state (FIG. 7B), the three sets of plate bodies 18a to 18c are in a linear state to hold the fully opened state of the cylinder cover 14. Here, a handle 18e is further provided on the plate body 18a, and the cylinder cover 1
The opening / closing operation of No. 4 can be performed without directly gripping the cylinder cover 14, and the handle 18e is designed so as to facilitate the opening / closing operation particularly in the half open state and the fully open state. .

In the embodiment of the present invention configured as described above, the auxiliary floor 8 is allowed to stand up in a standing posture so as not to get in the way during traveling on the road and during split work. Is the side cover 10
Since it is stored inside, the auxiliary floor 8 in the stored posture does not protrude beyond the side cover 10 as in the conventional case, and it does not become an obstacle.

That is, although the auxiliary floor 8 is extended to a position where it overlaps with the side cover 10 to secure a large auxiliary floor area, when the auxiliary floor 8 is in the storage posture, the extended portion has a side cover. The housing 10 is housed so as to be housed in a housing recess 10a formed by cutting out in the lower part of the housing 10. As a result, when the auxiliary floor 8 is stored, the side cover 1
The extension of the auxiliary floor 8 that overlaps with 0 does not stick out to the outside as in the conventional case, and the danger that the auxiliary floor 8 may hit people or objects when traveling on the road is surely avoided. It will be possible.

In addition, the paddle receiving portion 4 side of the traveling machine body 1 such as splitting work,
In other words, if there is also uncut culm on the right side of the machine, this uncut culm will be slid on the right side of the traveling machine body 1 after being weeded by the divider 13, The tip end of the culm is slidably guided by the side cover 10 located outside the auxiliary floor 8 at the overlapping portion between the auxiliary floor 8 and the side cover 10, so that the front end of the auxiliary floor 8 The uncut culm that has passed through the overlapping portion without being caught by the sliding guide and is slidably guided to the rear end of the side cover 10 is smoothly inherited to the outer surface side of the auxiliary floor 8. As a result,
The uncut stem culm is broken based on the catch of the uncut culm on the auxiliary floor 8, the grain is shed from the uncut culm, and the uncut culm is pulled out from the field. It can be surely prevented, and it can greatly contribute to the improvement of the efficiency of the harvesting work.

Further, the storage recess 10a is formed in an inclined shape so as to be higher toward the rear side, and when the auxiliary floor 8 is stored, a predetermined interval is present along an inclined surface formed on the outer edge of the front end portion of the auxiliary floor 8. Therefore, various culm lengths (however, the storage recess 10a
It is possible to smoothly inherit uncut stem culms having a height equal to or higher than the front end height) from the side cover 10 to the outer surface of the auxiliary floor 8. That is, when the accommodating recess 10a is formed in a stepped shape, the sliding contact guide height of the side cover 10 suddenly rises from the overlapping portion, so that the uncut stem culm having a short culm is guided by the side cover 10. There is a risk that the storage recess 10a may enter the storage recess 10a without being received and may be caught by the front end of the auxiliary floor 8. However, since the storage recess 10a of the present embodiment is formed in an inclined shape so as to become higher toward the rear side, The height of the sliding contact guide gradually increases from the overlapping portion, and thus even an uncut stem with a short culm is subjected to the guide action by the side cover 10 and enters into the storage recess 10a based on the guide action. It will certainly be regulated. As a result, the uncut stems will not be caught on the front end of the auxiliary floor 8 and will be smoothly inherited to the outer surface side of the auxiliary floor 8.
It is possible to more reliably prevent the inconveniences such as the uncut stem cules being broken, the grain being shattered from the uncut stems, and the uncut stems being pulled out of the field based on the catching of the uncut stems.

Of course, the present invention is not limited to the above-mentioned embodiment, but the side cover may be a wide one extending to the lower part of the body instead of the strip shape as in the above-mentioned embodiment. The storage recess can be formed so as to be cut out from a portion facing the front end portion of the auxiliary floor as shown in FIG.

[Advantages] In short, since the present invention is configured as described above, an extension portion that extends forward from the front end position of the paddy receiving floor portion and overlaps the airframe side surface cover is provided at the front end portion of the auxiliary floor. While the auxiliary floor area is expanded by forming the above, the extension part of the side cover of the fuselage is extended below the extended portion while avoiding interference with the side cover of the fuselage in the auxiliary floor storage posture. Since the storage recess is formed so that the installation part can be stored inward of the machine side cover, the auxiliary floor can be stored without protruding from the machine side cover, and as a result, the auxiliary floor can be stored when traveling on the road. It is possible to surely avoid the danger that a person hits a person or an object and significantly improve safety.

In addition, if there is uncut culm on the side of the paddy receiving floor of the traveling machine as in the middle splitting work, etc., this uncut culm is provided with the paddy receiving floor after being weeded at the front end of the machine. Although it will be in sliding contact with one side of the machine body, the tip side of the uncut culm that is in sliding contact with the side surface of the machine body located outside the auxiliary floor in the overlapping area between the auxiliary floor and the machine body side cover. Since it is guided by sliding contact,
The uncut culm that has passed through the overlapping portion without being caught by the front end of the auxiliary floor and is slidably guided to the rear end of the side cover of the machine is smoothly inherited to the outer surface side of the auxiliary floor. As a result, the uncut culm is broken based on the catch of the uncut culm on the auxiliary floor, the grain is shed from the uncut culm, and the uncut culm is pulled from the field. The inconvenience can be surely prevented, and it can greatly contribute to the improvement of the efficiency of the harvesting work.
