Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a reaping section side cover in a combine harvester.

[Prior art]

A combine harvester has a reaping section at the front of the machine.

The front end of this cutting section is equipped with a plurality of cutting bodies that push through the culms that are planted in the field. Behind that, a lifting device for erecting the fallen shell culm is installed with a slight inclination to the rear. Further, behind the pulling device, there are provided a cutting blade for cutting the stem portion of the erected shell culm, and a culm conveying device on the stem side and the tip side for capturing and conveying the cut culm.

This type of shell culm conveying device in the reaping section uses an endless chain and a clamping lever biased by a strong spring member to hold and transport the shell culm.

For this reason, it is extremely dangerous if your hands or clothes get caught in it, and if the uncut culms in the field get caught, you will lose grain, so conventionally, the sides of the main part of the harvested area are generally covered with side covers. covered. Since it is often necessary to remove this side cover for inspection and maintenance of the conveyance device, or for removing culms and weeds stuck in the conveyance device, conventionally it has been provided in a removable manner. . This attachment/detachment method includes tightening bolts to a lifting device or the like, and fitting an engaging body to a receiving member as described in Japanese Utility Model Application Publication No. 62-204442.

[Problem to be solved by the invention]

The conventional method of tightening with bolts required loosening and tightening the bolts when attaching and detaching.
There were also inconveniences such as the hassle of aligning the holes, which took a long time, and the bolts that had been loosened and removed could be lost.

In addition, in the configuration described in the above-mentioned Japanese Utility Model Publication No. 62-204442, although the attachment/detachment method itself is simple, the fixing method is simply to fit the engaging body to the receiving material, so the strength is insufficient. . In addition, a fixed side cover is provided separately behind the easily removable side cover, which poses an obstacle to maintenance of the reaping section.

[Means to solve the problem]

This invention takes the following technical means to solve the above-mentioned problems.

That is, in front of the fuselage engineer, there is a grass cutting body 2, a shell culm lifting device 3.
Cutting blade 4, plant head side conveyance device 5. A reaping section 8 consisting of a tip side conveying device 6, a raking device 7, etc. is provided, and the front side faces the side of the culm pulling device 3, and the lower part is wider than the upper part. In the case where a cover 9 is provided, an engaging body 11 that engages with a support 10 provided from the reaping part 8 side is provided on the lower side of the side cover 9, and an engaging body 11 that engages with a support body 10 provided from the reaping part 8 side is provided on the upper side of the side cover 9. Engage with the provided support 12
This is a reaping section side cover for a combine harvester, characterized in that it is provided with a locking device 13 that can be detached.

[Action/effect of the invention]

When the machine body 1 is moved forward to perform the reaping and threshing operation, the conveyance system of the reaping section 8 may become clogged due to oversupply of culms, shedding of stumps, incorporation of weeds, etc.

When performing maintenance on the reaping section 8, the operator first operates the locking device 13 provided on the upper side of the side cover 9 to unlock the support body 12. Then, lift the side cover 9 as it is and remove the lower engaging body and support body]
When O is removed, the side cover 9 is removed from the reaping section 8.

In this way, since the side cover 9 can be removed with one touch, work efficiency can be improved.

The same applies when attaching the side cover 9 to the reaping section 8.

Furthermore, since the side cover 9 and the upper locking device 3 are integrally constructed, there is no inconvenience such as the aforementioned loss of bolts.

Since the sides of the reaping section 8 are covered only by the side covers 9, simply by removing the side covers 9, the sides of the reaping section 8 are completely opened, allowing easy maintenance.

〔Example〕

An embodiment of this invention will be described.

The construction is a machine body, with a traveling device 4 attached to the lower part and a threshing device 15 mounted on the upper part. Reference numeral 8 denotes a reaping section provided on the machine body 1 so as to be movable up and down by a hydraulic cylinder 16, and a supply conveyance device 17 is provided between this reaping section 8 and the threshing device 15.

In the reaping section 8, a weed splitter 2 is provided at the front end of the reaping frame 18, and a culm pulling device 3 is provided behind it. 4 is a cutting blade. A scraping device 7 for scraping the shell culm is provided behind the shell culm pulling device 3. Furthermore, behind this, a plant side conveying device 5 and a tip side conveying device 6 for pinching and conveying the cut culm are provided extending rearward.

These raking device 7, stock side conveyance device 5, and tip side conveyance device 6. The cutting blades 4 and the like are transmitted from a gear case 19. In addition, the culm lifting device 3 is connected to the longitudinal transmission pipe 20 from the gear case 19.
, and is configured to be driven via a horizontal transmission pipe 21. Furthermore, 22 is a reinforcing pipe that connects the end of the horizontal transmission pipe 21 to the reaping frame 18 and the like.

Therefore, supports [0] and O, which are made by welding round rods 24 to plate bodies 23, are fixed to the reaping frame 18 at two locations, front and rear. Further, a support body 12 having a U-shape in side view is fixed to the narrow portion of the reinforcing pipe 22.

The side cover 9 has a lower part wider than an upper part.

A hook-shaped engaging body 11 that engages with the support body IO is fixed to the inner lower part thereof. Also.

A locking device 13 is provided at the upper part 6 The locking device 13 is arranged so that the upper part of the handle 25 is attached to the axis P in the recess opened on the outer surface of the side cover 9.
A hook-shaped member 2 is integrally attached to the handle 25.
6. still.

A spring 27 is provided that urges this hook-shaped member 26 to rotate upward. And this hook-shaped member 2
6 is a structure that engages with and locks the support body 12.

Although the right side surface of the reaping portion 8 has been described above, the same locking configuration is adopted for the left side surface.

Figure 2 is a side view of the reaping section, Figure 3 is I-1 in Figure 2.
