Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain rod pulling device that is installed in front of a harvesting machine such as a combine harvester or a binder in conjunction with the function of a tiller, and adjusts the vertical and horizontal posture of grain culms. In particular, the present invention relates to a grain culm lifting device that has the function of erecting and plowing up grain culms that are lying down laterally perpendicular to the direction of movement after harvesting.

Conventionally, in grain culm lifting devices that are attached to the pre-processing part of harvesting machines such as combines and binders together with a weeding device to adjust the posture of grain culms, the tines for grain culm lifting are installed in the direction of movement of the machine. On the other hand, due to structural constraints that allow it to move upward only diagonally backward in a plane perpendicular to the plane, it has the disadvantage that it does not work to raise the grain culm that is lying down perpendicular to the direction of movement of the aircraft.
There was a disadvantage that uncut leaves were left after the harvesting machine had traced the area.

In addition, there was a problem in that the tips of the ears were intertwined with each other when they were lying down in the uncut area rather than in the harvested area, making it impossible to plow them up.

The object of the invention is to eliminate the drawbacks of the above-mentioned prior art,
It solves the problems, eliminates the disadvantages, and is more efficient because it not only lifts the grain rod in the vertical and horizontal directions, but also plows it up.
The purpose of this project is to develop a new device that can perform efficient and highly accurate harvesting and harvesting.

The structure of the present invention in accordance with the above object is to cross the culm which is lying down perpendicularly to the direction of movement of the aircraft in the vertical direction, that is, from below in the direction of movement of the aircraft, and open the intermediate part of the weeding device. The gist of the present invention is to scoop up the weeded culm, pull it up, plow it up, and stand it upright so that the culm is in a state suitable for reaping and transporting.

Hereinafter, a detailed description will be given based on the embodiments shown in the drawings.

16) close to the lifting case (11) and fixed to the machine rest in a front low and high slope shape, and the tip of the case (11) is positioned near the outside of the rear end of the dividing rod (15). A long groove (13) is formed on the top surface of the case (11) through which the weeding protrusion (12) can protrude and move, and is attached at regular intervals to a rotating chain (14) inside the case (11). The auxiliary pulling device (B) is constituted by providing the weed protrusion (12) so as to protrude from the long groove (13) to the outside of the case (11) and move along the long groove (13) in a direction facing direction. .

The range of movement of the weeding protrusion (12) in the upward position is the long groove (

(C) shows the separation device, which is located in front of the main stem culm pulling device (A), and is tilted forward so that the front end is close to the ground plane and the rear end is high, almost in the direction of the aircraft. The dividing rod (16) is fixed to the front width of the dividing rod (10), and the front end of the dividing rod (16) is fixed to the front width of the dividing rod (10).
16) and the case of the auxiliary lifting device (B) is shown in side view.
The upper surface of the case (11A) is located approximately in the center of the case (11).
), the divider (1) is rearranged at a distance to the side of the case (11) in plan view, and the distance from the case (11) can be changed with an adjuster (17).
6), the divider tip (16A) of the divider (16) is inclined in plan view toward the side of the fuselage, and the divider side (16B) is located outside of the main culm pulling device (A). They are arranged almost parallel to each other. The above divider (1
6) and the main stem culm pulling device (A), the auxiliary pulling device (B) is located, so that the weeding protrusion (12) can be
In plan view, the inner surface of the action side of the lifting case (1) (
1A) and the divider side part (16B), and the case (11) of the auxiliary lifting device (B).
The tip of the case (11B) is the dividing rod (15) when viewed from the side.
and the main stem culm pulling device (A), there is a dividing rod (1
5) and the divider tip (16A).

When the machine moves in the direction of the arrow (A) in a field of grass, rice, wheat, etc., the dividing rod (16) at the side tip of the machine remains upright with the stem culm to be harvested and the side stem stick that is not cut. The grass is divided by digging into the root side, and as the machine moves forward, the upper part of the uncut side stem culm is brought to the outside of the machine by the divider (16), and at the same time, the grass is separated by the weeding rod (15). The planted stem culm that has been guided into the pulling path (D) is pulled up from the root side to the upper side by the lifting tines (2) of the main stem culm lifting device (A), and the cutting blade ( 4), the roots are harvested, guided by a conveyance guide plate (8), bound into a fixed bundle by a binding device (7), and released into the field on the harvested side.

At this time, before the grass is divided by the molecular rod (15) and subjected to the lifting action by the main stem culm pulling device (A), the tip of the auxiliary pulling device (B) located in front of the lifting case (1) The weeding protrusion (12) acts, and the auxiliary pulling device (B
) Since the weeding rod (15) and the divider tip [16A] are located in front and to the side of the case tip (11B), the auxiliary puller can be used after the weeding action by the weeding device (C) has started. The weeding protrusion (12) of the weeding device (B) acts.

In addition, although the grass is separated by the grass dividing rod (15) and is pushed outward by the planting stem divider (16) on the uncut side, the cutting is guided to the pulling path (D). When it is entangled with the upper side of the stem culm, the weeding protrusion (12) that moves upward in the direction of arrow (b) comes into contact with the upper side of the planted stem rod on the uncut side and is forced to As the stems are engaged with each other, the entanglement between the grooves is broken, and the planted stems on the uncut side are pushed aside by the divider (16). At this time, since the weeding protrusion (12) is located above the divider (16), if the planting stem rod is entangled with the cutting stem culm, it will be in a state of being curved toward the raising case (1). The weeding projections act effectively and act on the curved stem culm, making weeding easier. In addition, the auxiliary lifting device (B) is not in the form of a flat strip, but has protrusions similar to those of the conventional pulling device that rotate around and leave a space between the dividers, so that the culms of the planted stems that are entangled as described above can be separated. The inwardly curved state and the protrusion (12) protruding into the stem culm produce a loosening effect on the entangled planting stems, thereby improving weed separation.

In addition to the conventional horizontal main stem culm pulling device, the present invention is equipped with a vertical auxiliary pulling device in which a weeding protrusion opens in the middle part of the weeding device and rotates along the traffic direction. Since the grain culm/stem culm pulling device was constructed using the above method, the ability to pull up the lodging grain culm in all directions was significantly improved, eliminating uncut areas. Since the reaping direction is not restricted by the lodging direction of the grain culm, it is also effective for reaping bent rows of rice, etc.

In addition, since the plowing action functions smoothly, grain culms lying on the unharvested side are raised and harvested in an orderly manner, so there is no shedding, and in addition, there is no variation in the amount transferred to the threshing section. Therefore, there is a ripple benefit in that problems such as grain clogging do not occur.

In addition, since the weeding device has the same gap, the weeding protrusion of the puller can come out from the gap and rise, so that
The grass culling device can reliably carry out a baton touch while retaining the grass cutting function, and the length of the grass culling device can be substantially shortened, which has the effect of making the machine body more compact.
