Description

[Detailed Description of the Invention] The present invention relates to a combine harvester in which the handling depth can be adjusted by integrally swinging the stock clamping and conveying device, the tip locking and conveying device, and the tip guide cover up and down. .

In this type of combine harvester, the tip guide cover is configured to be as small as possible (thereby, it is possible to monitor the state of conveyance of the culm by both the conveyance devices and to improve the visibility to the front lateral outer part of the machine body.

Furthermore, by providing the operating lever for adjusting the handling depth at a high position near the driver's seat and near the conveyance end of the ear locking and conveying device, the operator can easily adjust the handling depth. , these two points are closely related to each other.

That is, if the tip cover is made smaller, it is advantageous in terms of work management of the machine as described above, but on the other hand, since the operation lever for adjusting the handling depth protrudes long upward from the rear end of the tip guide cover, it is especially difficult to make the tip cover smaller. When the long culm is transported, the tip of the shell culm comes into contact with the operating lever, which tends to cause damage such as shedding, and if the tip cover is made larger, damage such as shedding can be reduced, but on the other hand, There is an inconvenience that the monitoring of the shell culm conveyance state by both conveyance devices and the visibility to the front lateral outer part of the fuselage are extremely poor.

In view of the above-mentioned circumstances, the present invention aims to suppress damage such as shedding caused by the tip of the culm transported by the two transport devices coming into contact with the operating lever, while using a cover of minimum size. It is designed to enable
The apparatus is characterized in that when each of the conveying devices and the ear guide cover are swung upward, the operating lever is positioned on the back side of the ear guide cover with respect to the culm conveyance path. be.

That is, in the combine harvester according to the present invention, the tip guide cover is configured to be as small as possible to improve the visibility of both the conveying devices (for monitoring the state of conveying the culm and for the front and lateral outer parts of the machine body). An operating lever for adjusting the depth is provided at a high position near the conveyance end of the tip locking and conveying device near the driver, so that the operator can easily adjust the handling depth. When the handling depth is adjusted to be shallow during conveyance, that is, when both of the conveying devices are swung upward, the back side of the tip guide cover (this operation lever can be scraped), so that the handling depth is adjusted to be shallower. This has made it possible to sufficiently suppress damage such as shedding caused by the tip of the culm coming into contact with the operating lever.

Embodiments of the present invention will be described in detail below based on the drawings.

Figure 1 shows a combine harvester, which is equipped with a clipper-type reaping device 6, which engages with the base of the planted culm near the ground in front of the reaper 6, and pulls it up and conveys it upward to the rear of the machine. Between the reaping unit 8 consisting of the pulling device 7 and the threshing device 9 mounted at the rear of the machine, the stock base of the culm that has been harvested in a vertical position is held between the feed chain 9AJ of the threshing device 9. A stock head clamping and conveying device 1 that conveys and supplies this, an ear-end locking and conveying device 2 that engages with the tip of the cut husk culm in an upright shape and conveys and supplies it to the supply port 9a of the threshing device 9, and (
This is located in an inclined position above this ear locking and conveying device 2, and guides the tip of the cut culm conveyed by both the conveying devices 1 and 2 in a leaning state (on the supply port 9a side). The tip guide cover 3 is installed so as to be integrally swingable up and down around the axis of the pivot shaft 11 of the support frame 10 to which the reaping section 8 is attached and which is swingable up and down.
Between the two transport devices 1, 2 and the support frame 10 (this,
A handling depth adjustment mechanism 12 is provided for adjusting the handling depth by swinging the both conveying devices 1, 2 and the tip guide cover 3 around the axis of the pivot shaft 11, and the handling depth adjustment mechanism 12 is provided. The operating lever 4 of the mechanism 12 is placed near the width direction side of the driver's seat 5 provided on the side of the fuselage, and the tip retaining conveyance device 2
(This is provided at a high position near the end of the conveyance, and when the conveyance devices 1, 2'j6 and the tip guide cover 3 are swung upward around the axis of the pivot shaft 11, the operation lever 4 is It is configured to be located on the back side of the tip guide cover 3 with respect to the culm conveyance path.

As shown in FIG. 2, the handling depth adjustment mechanism 12 is configured such that an arm 14 having a groove shape in side view is attached to a fixing member 13 fixed to the support frame 10 and having an 8 shape in side view.
The partially arcuate flange 13a of the identification member 13 (with a plurality of engagements formed therein) is attached to the cylindrical member 15 constituting the operating l/bar 4, which is pivotally attached to the upper end Q of the swing arm 14 and fixed to the upper end Q of the swing arm 14. A dog-shaped operating rod 17 having a locking protrusion 17a that can be fitted and locked is selectively inserted into the locking hole 16, and is formed at the upper end of the cylindrical plate 15. The locking protrusion 17a is inserted between the stepped portion 15a and the operating knob 18 provided at the upper end of the operating rod 17 in the locking hole 16 (in the direction of fitting and locking). And,
The other end of the link 20 that is pivotally supported on the other end of the swing arm 14 is pivotally connected to a connecting member 21 that connects both the conveying devices 1 and 2, so that the operating knob 18 is controlled by the elastic force of the spring 19. The locking protrusion 17a and the locking hole 1 are pressed downward against the
6 is released, and by swinging the cylindrical member 15 around the pivot point of the swinging arm 14,
The handling depth is adjusted by vertically swinging both the conveying devices 1, 2 and the tip guide cover 3 about the axis of the pivot shaft 11.

In addition, a cutting husk guide plate 22 pressed into a cross-sectional road shape is placed at the supply port 9a of the threshing device 9, with the rising portion 22a located on the side of the driver's seat 5 and protruding forward in the direction of movement of the machine. At the same time, one end thereof is provided with the reaped husk culm guide plate 2 at the conveyance terminal end of the ear tip guide cover 3.
An elastic membrane body 23 having a substantially similar shape to the guide plate 22 is provided on the free end of the guide plate 22.

When such an elastic membrane body 23 is provided, there is an advantage that dust particles such as rice grains can be suppressed from scattering toward the driver side.

In addition, 24 in the figure is a reaping part lifting/lowering operating arm that swings and lowers the support frame 10 around the axis of the pivot shaft 11.
