Description

[Detailed explanation of the invention] This invention is designed to prevent the planting culms that are separated from the left and right sides as the aircraft advances, and the planted culms that are separated to the uncut land side to have a tendency to fall over themselves. At the same time, it is designed to prevent workers from collapsing inward to the inside of the machine, and to ensure personal safety so that workers do not accidentally insert their hands into movable parts, including the culm lifting device, etc. The present invention relates to a reaping harvester in which a side cover is provided on the rear, lateral, outer side of the hoisting device.

A conventional side cover has been formed entirely into a substantially flat surface.

Although this side cover met the requirements for human safety, it created a new problem: grain shedding due to contact between the side cover and the stem culm on the side of the uncut field.

The purpose of the present invention is to make it possible to reliably and smoothly transport the planted stem culms on the uncut field side to the rear of the aircraft sideward and outward with little damage such as shedding by simply improving the structure of the side cover. The point is to try to make it possible.

The technical means of the present invention taken to achieve the above-mentioned purpose is that during the reaping operation, the culm pulling device is placed at the rear, lateral, outer side of the stem culm pulling device located on the uncut field side, and at the rear position of the weeding tool. , a flat surface portion extending toward the rear of the machine body approximately along the outer edge of the case on the uncut land side of the pulling device is provided at the upper position, and the lower portion is lower than the sugar part of the planted stem culm on the uncut land side. A side cover is provided with a bulging surface portion at a lower position that is expanded laterally and outwardly further than the flat surface portion so as to come into contact with the stem culm at a lower position, and the bulging surface portion is in the direction of movement of the aircraft. When viewed from above, it is provided at approximately the same position as, or slightly inward from, the side edge of the uncut field side of the rear end of the weed divider.

As a result of taking the above-mentioned technical measures, even if the planted stem culms tend to fall inward to the inside of the machine after being divided by the weeding tool,
The planted stem culm on the uncut land side is guided to the rear of the machine by the abutting action at a position lower than the sugar part of the bulging surface portion, without causing it to fall inward to the machine body, and is connected to the side cover. The occurrence of shedding due to sliding contact with the sugar part of the stem culm is avoided as much as possible, and smooth distribution in the draft can be achieved.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIRST EMBODIMENT FIG. 1 shows a clipper-type reaping device 3 and a culm lifter that engages with the base of a planted culm near the ground in front of the reaping device 3 and pulls it up and conveys it upward to the rear of the machine. device 1 and
The stalk culm, which has been harvested in an upright position, is gradually changed into a sideways position, and is conveyed to the supply port 4a and feed chain 4A of the threshing device 4 mounted at the rear of the machine. A combine harvester is shown which is equipped with a pre-reaping processing section 7 consisting of a clamping and conveying device 6.

This combine harvester includes a lateral outer surface of the pulling device 1 located on the uncut field side during the reaping operation, and a
As shown in FIG. 2, a weeding tool is provided at the tip of a weeding support rod 9 extending from the mowing device 3 side to the front of the machine between the transmission case 8 that transmits power to the 10...
Among them, a side cover 2 which also serves as a safety cover for preventing the planted stem culms on the uncut land side, which have been divided by the weed cutting tool 10 located on the uncut land side, from lodging toward the inside of the machine. Installation.

A lower portion (bulging surface portion) 2B of the side cover 2 that contacts the planted stem culm at a position lower than the tip of the planted stem culm is configured to bulge outward from the side of the body than the upper flat surface portion 2A. And, so that the bulging surface portion 2B is located slightly inward from the side edge of the uncut land side of the rear end of the weeding tool 10 when viewed in the direction of movement of the machine,
When viewed from the front, the structure is roughly stepped.

Further, the front end portion 2b of the bulging surface portion 2B in the aircraft traveling direction
is formed into an inclined surface that is located laterally outward toward the rear in the direction of movement, and the portion of the bulging surface portion 2B corresponding to the lifting start end 1A of the lifting device 1 is a stem culm lifting claw. 11... is formed with a recessed part or notch part 12 that allows the protrusion and rotation of the parts.

Second Embodiment FIG. 3 of the drawings shows a second embodiment of the present invention. It differs from the first embodiment described above in that it is provided at approximately the same position as the side edge of the uncut field side of the end portion.

Since the second embodiment has the above configuration, the above-mentioned first embodiment
Compared to the embodiment, the transition of planting stems and culms from the weeding tool 10 to the side cover 2 can be performed better.

Third Embodiment In the first embodiment described above, the lower portion 2 of the side cover 2 is
In the third embodiment shown in FIG. 4, a notch 12 is formed in B to allow the stem culm lifting claws 11 to protrude and rotate. In the third embodiment shown in FIG. A side cover 2 is provided to cover the protruding and rotating parts of...
