Description

[Detailed description of the invention] This invention is designed to move the fallen stem culm from the lower front to the rear in the plane along the direction of movement of the machine, on the side of the introduction route of the stem culm to the reaping device equipped with a side-rotating type forced pulling device. The present invention relates to a reaping machine equipped with a vertically rotating forced weeding device configured to rake up and transfer grass by a locking claw that moves upward.

This type of reaper uses a vertically rotating forced weeding device to remove planted stem culms that are to be harvested and have fallen to the point where they cannot be pulled up by a horizontally rotating forced pulling device. To ensure the pulling by supplementary pulling and transferring to a forced pulling device, and when the planted stem culm to be reaped and the non-target stem culm that are adjacent in the left and right directions are intertwined,
Because it was developed with the aim of raking up and transporting both of them, and also allowing for smooth weeding to the left and right, the locking claw of the forced weeding device is always on the raking and transporting path. It was designed to move protrudingly over the entire area.

Therefore, the forced weeding device cannot be locked even for planted stem culms that are in a standing state that can be sufficiently pulled up by the forced weeding device alone, or for planted stem culms that are short in height. The claws act in the same manner as in the case of a planted stem culm with a high degree of lodging, and there is a drawback that the improper raking action of the tip of the stem culm by the locking claws tends to cause grain shedding or breakage.

In view of the above-mentioned circumstances, the present invention has been developed to ensure that when the planted stem culm is in a state of lodging, the forced weeding device can perform the desired weed raking and transport action, while at the same time ensuring that the planted stem culm is The purpose of this is to allow the grass to be divided smoothly from side to side without causing shedding or breakage when the grass is in a standing state or is short. In the above-mentioned forced weeding device, on the raking and transfer action side,
A guide rod for weeding is provided with an inclination angle to the ground that is larger than the inclination angle to the ground of the path of action of the pawl so that the claw protrudes only in the lower part of the transfer path, and the guide rod for weeding is moved between the operating state and the non-operating state. It is characterized by being configured so that it can be switched between the operating state and the operating state.

As a result, when the planted stem culm is in a erect state or is short, the weeding guide rod provided on the raking and transfer action side of the forcible weeding device is switched to the operating state, and By protruding the locking pawl only at the lower part of the raking transfer path, the weeding between the stem culm to be reaped and the adjacent stem culm not to be reaped is reliably performed. It is possible to reliably avoid grain shedding, breakage, etc. caused by the action also on the culm tips.

However, if the planted stem culm is significantly lodging,
By switching the guide rod for weeding to a non-operating position and causing the locking pawl to protrude over the entire area of the weeding transfer path, the intended weeding and transferring action by this forced weeding device is ensured. We have finally reached the point where we can demonstrate this.

Embodiments of the present invention will be described below based on the drawings.

The drawing shows a combine harvester, in which the locking claws 2A are arranged in front of a threshing device 1 mounted at the rear of the machine so that they can be rotated in a plane that is inclined rearward and upward with respect to a horizontal plane along the direction of movement of the machine. A pair of horizontally rotating forced pulling devices 2, 2, and a clipper-type cutting blade that cuts the base of the planted shell culm (planted stem culm) pulled up by both forced pulling devices 2, 2. 3 and a reaping device 5 consisting of a vertical conveying device 4 that gradually changes the posture of the harvested husk to a sideways posture and supplies it to the conveying start end of the threshing feed chain 1A, and the forcible pulling device 2, 2, this forced pulling device 2 is located on the lateral outer side of the forced pulling device 2 located on the lateral outer side of the machine on the side where the threshing feed chain 1A is present.
The planted shell culm introduced into the culm introduction path A is raked up and transferred by the locking claw 6A that moves from the lower front to the upper rear in a vertical or nearly vertical plane along the direction of movement of the aircraft. A vertically rotating type forced weeding device 6 is provided.

The forcible weeding device 6 is constructed as follows.

That is, the weeding frame, which has a rectangular shape in side view, is constructed from the tip of the weeding support rod 7 and the front end of the reaping frame 8, which also serves as the transmission case, to the upper end of the transmission case 9, which is erected upward. 6
The locking pawl 6 is disposed within B and over the sprockets 6C provided at both upper and lower ends and at the bent portion thereof.
An endless chain 6D is attached to the weed cutting frame 6B so that the weed cutting frame 6B can be raised and lowered freely. After the locking claw 6A is raised and protruded, the locking claw 6A is
a pawl raising cam 6E that vertically moves the locking pawl 6A at the lower front end of the weeding frame 6B; a pawl guide rail 6F that moves the locking pawl 6A along the raking transfer path B while maintaining the raised protruding position; A claw retiring cam 6G made of rubber is provided for retiring the locking claw 6A that has moved to the end of the raking transfer path B into the weeding frame 6B.

Then, at the peripheral edge of the claw protruding opening on the raking transfer action surface side of the weed division frame 6B, the raking transfer path is placed at three locations appropriately spaced apart in the longitudinal direction of the raking transfer path B. The cylindrical members 10... are fixed, and the claws 6A are tilted relative to the ground so that the claws 6A protrude only in the lower part of the raking transfer path B. The free end of a rod-shaped member 11A fixed to both the upper and lower ends of the weeding guide rod 11 and the longitudinal center thereof, which has an inclination angle to the ground that is larger than the angle θ1, is inserted and held so as to be able to swing freely. Then, the guide rod 11 for weeding is attached to the cylindrical member 1.
By swinging around the axis of 0..., it is configured to be switchable between an active state in which it protrudes toward the front of the fuselage and a non-operative state in which it protrudes toward the rear of the fuselage.
