Description

[Detailed Description of the Invention] This invention relates to a weeding device disposed at the front end of a reaping machine such as a combine harvester.

Conventionally, this type of weeding device has a structure in which a weeding part is installed at the front end of the reaper body, and a weeding plate is installed diagonally from the tip of the cutting frame to the lower part of the lifting case. The grass divider plate fixed to the aircraft was installed at a certain angle with respect to the aircraft.

However, the field conditions in which such a reaper is used vary widely, and the reaper has the disadvantage that the weed cutting board may not be able to reliably divide the grass.

The present invention was developed in response to these circumstances, and the object is to provide a weed cutting device for a reaper that can change the inclination of the weed cutting board depending on the field condition. .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, a combine harvester to which the weeding device of the present invention is applied is shown, and a reaping part 2 disposed at the front end of the machine body 1 has a three-piece harvester that protrudes forward from the lower part of the front end of the machine body 1. A book reaping frame 3, a lifting case 4 installed obliquely at the upper part of the front end of each of the reaping frames 3 and having a lifting chain disposed therein, and a rear end attached to the front end of each of the reaping frames 3. The grass dividing plates 5a and 5b are raised and extend toward the bottom of the case 4, and the grass dividing plates 5a and 5b located on both left and right sides are diagonally rearward from the bottom of each of the grass dividing plates 5a and 5b toward the sides of the fuselage 1. A diagonally installed auxiliary grass divider 6,
The cutting blade 7 is provided on the proximal end side of the cutting frame 3.

As shown in FIG. 2, the reaping frame 3 has the following features:
It is composed of a main body part 3b that is installed obliquely from the body 1 side, and a substantially horizontal connecting part 3a that is formed separately from this main body part 3b and has a grass divider plate 5a fixed to its tip. The connecting portion 3a is connected by a nut 15 and a bolt 14 via a connecting rod 13 bent at an obtuse angle as shown in FIG.

Therefore, in this embodiment, connecting rod 1
3 by 180 degrees to connect the main body part 3b and the connecting part 3a, the angle of the connecting part 3a of the reaping frame 3 can be adjusted, as shown in Fig. 4 A and B. Connecting parts 3a can be connected so that they are approximately horizontal for reaping work in flat fields, or the inclination angle of connecting parts 3a can be adjusted so that the main body part 3b
The front part of the machine body 1 may lift up during reaping work in wet rice fields, and in such cases, the connecting part 3a can absorb the tilt of the machine body 1. Reaping work can be carried out smoothly by keeping the surface level.

Further, in this embodiment, a plow body 8 is attached to the outside of each grass dividing board 5a, 5b located on both the left and right sides.

This plow body 8, as shown enlarged in FIG.
It has a substantially triangular shape when viewed from the side, and is removably fixed to the tip of the reaping frame 3 with a pair of bolts 9 and nuts 10, and the lower part 8a of the plow body 8 extends downward from the reaping frame 3. The lower part 8b is designed to cover the upper part of the outer half of the front part of the grass dividing board 5a, and the tip 8c projects forward from the tip of the cutting frame 3.

Therefore, according to the weeding device of this embodiment,
As shown in Figure 6 A and B, the grass dividing boards 5 on both the left and right sides
During reaping work, the plow body 8 attached to the outside of the grass cutting board 5a advances while removing the mud 12 outside the two rows of crops 11 to the opposite side of the crops 11, and then The crops 11 that have been separated by the grass cutting boards 5a and 5b are cut by the cutting blade 7.

Therefore, before cutting the crop 11 with the cutting blade 7, the mud 12 outside the two rows of the crop 11 is removed from the crop 11.
Since the mud 12 is removed to the opposite side, there is no risk that the cutting blade 7 will be covered with the mud 12, and as shown in FIG. The position of the reaping frame 3 can be lowered to the limit or below the ground surface, and the height at which the crop 11 is reaped by the cutting blade 7 can be lowered. Furthermore, when scattering chopped straw onto the field from the waste straw discharge section (not shown) at the rear of the machine 1, if the wind direction is bad, the scattered cut straw may collect at the base of the crop 11 to be harvested. However, even in such a case, the plow body 8 removes the cut straw, making the reaping work extremely easy.

In addition, although the above-mentioned example shows the case where it is applied to a combine harvester for two-row cutting, it is not limited to two-row cutting, but can be applied to combine harvesters and other reaping machines such as single-row cutting and three-row cutting. In particular, when applied to a single-row reaper, the crop can be harvested after removing mud on both sides of the crop, eliminating the risk of the cutting blade being covered with mud during reaping work, and also lowering the cutting height to the very edge of the ground. Furthermore, if the harvester is of a type that discharges cut straw, the cut straw discharged during the reaping operation can be mixed into the mud.

As is clear from the above description, according to the weeding device for a reaper according to the present invention, the reaping frame is formed separately from the main body portion and the connecting portion, and
Since the main body and the connecting part are removably connected by a connecting rod bent at an obtuse angle, the inclination of the weed dividing board can be changed depending on the field conditions, improving the efficiency of reaping work. be able to.
