Description

[Detailed description of the invention] The present invention is equipped with a planting stem culm pulling device at the front of the reaping device, and a raking device at the rear of this lifting device that forces the stem culm toward the center of the cutting. Relating to a harvesting machine with a raising device such as a combine harvester or a binder in which the device is arranged.

In this type of conventional reaping/harvesting machine, in order to reliably and smoothly guide the raised planted stem culms toward the center of the row, the raking action starting end of the forced raking device is moved by the raking device. A structure was adopted in which the stem was extended to a position immediately after the culm, but in this case, not only was the structure complex, but the stem culm was forcibly brought together and guided, so the stem culm would be severely damaged. Met.

In view of these points, the present invention has a simple structure and a structure that does not put strain on the stem culm by effectively utilizing the side safety cover for the raking device, while smoothly moving the stem culm in the center of the row. The purpose is to make it possible to guide the person closer to the person.

That is, in the reaping and harvesting machine with a raising device according to the present invention described at the beginning, a plate-like cover is installed upright to close the side of the forcible raking device and ensure safety for the operator. The upper half portion is curved inward to serve as a guide surface for guiding the tips of the stem culms that are pulled up by the pulling device and transferred to the reaping device side toward the center of the row, and this board The front edge of the shaped cover is attached to the back of the pulling device, and the lower edge is attached to the support rod of the weeding tool.

Therefore, according to the present invention, the safety cover is effectively used,
By simply improving the structure of this cover, it is possible to easily and smoothly guide the stem culms, which are pulled up by the lifting device and move toward the reaping device, toward the center of the row.
This eliminates the need for a large forced gathering guide device, resulting in a simple structure, while ensuring that the stem culms that are pulled up by the pulling device and transferred to the reaping device are gathered at a predetermined merging point. This made it possible to efficiently carry out the harvesting process after harvesting.

Moreover, since the pulling device is connected to the support rod of the weeding tool through this safety cover, in other words, this safety cover
In other words, it performs the same function as braces in buildings, so the vibration of the hoisting device can be reduced and hoisting performance can be greatly improved, and the stem culm during hoisting can be reduced. It becomes possible to raise the plants in an orderly manner by reducing posture holes, and as a result, it is possible to easily carry out the gathering and guiding action by the safety cover in a more favorable state with less disturbance in the stem culm posture. It is.

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

FIG. 1 shows a two-row reaping combine that is an example of a reaping and harvesting machine. In addition to the distribution, a supply conveyance section C for supplying and conveying the cut husk to the threshing section B and a driving section are disposed between both A and B.

As shown in FIG. 2, the reaping pre-processing section A includes three weeding tools 6 positioned at intervals in the lateral direction with respect to the direction of movement of the machine in order to weed the planted culms. - A pulling device 2 for raising the group and the divided planted culms into an almost vertical shape, and
A clipper type reaping device 1 for cutting the stock base of two raised culms is arranged sequentially from the front to the rear in the direction of movement of the aircraft, and the cut culm stock base is placed at the upper position of the reaping device 1. A scraping device 3 is provided to forcefully scrape into the center of the row.

The lifting device 2 tilts a pair of lifting frames 2A, 2A facing each other at a distance in the lateral direction and forming a common lifting path 7 for the two planted culms between them. In addition to providing the posture, these raising frames 2A.

Each of 2A has a large number of lifting claws 2B for locking and transporting shell culms.

2B...... is attached to the lifting chain 2C.

The forced raking device 3 is a rotary raking packer 3A that acts in contact with the stem near the base of the cut culm. The weeding tool 6...
... is the support rod 8 located in the front-back position...
It is attached to each tip, and the cross-sectional shape is C.
It is shaped like a letter, with both lateral ends extending inward.

Facing this, the combine harvester has a rear part of the lifting frames 2A, 2A and a reaping device 1 on both lateral outer sides of the forced raking device 3.
A plate-shaped cover 4, 4 is erected between the two.

By curving the upper half portions 4a, 4a inward, these covers 4, 4 are positioned in an inclined position that gradually approaches the center side during cutting as they move toward the rear, and are used to cut the tips of the reaped culms. It is configured to also serve as guide surfaces G and G that guide the guide to the center position.

The front edges of the covers 4, 4 are lifted up and the frames 2A, 2
The lower edge is attached to the back side of A, and the lower edge is attached to the upper surface of the support rods 8, 8 of the weeding tool 6.6 with screws 9, 9, respectively.
