Description

[Detailed description of the invention] This invention is designed to rake the base side of a plurality of planted stem culms into the central part using a pair of left and right rotary raking devices, so that they merge and harvest, similar to a combine harvester. Regarding reaping and harvesting machines.

In this type of stem culm guiding device, the stem culm introduced into the pair of right and left planted stem culm introduction paths is engaged with the pulling device until it is moved into the action area of the rotary raking device. Even in the case of a short culm where the culm ends, the culm can be placed securely within the action area of the raking device without causing the culm to fall over unexpectedly, and while loosening the entanglements between the left and right planted culms. In addition, if the planted stem culm is curved or
! Even if the machine body meanders and the planted stem culm is introduced to the lateral outer side of the planted stem culm introduction path, the planted stem culm is reliably guided into the action area of the rotary raking device. This is requested.

The present invention is capable of satisfying the above-mentioned two requirements by adding a simple structure. A first stump guide is provided in the part to guide the stump base of the planted stem culm to the action area of the rotary scraping device, and the first stump guide and A second stock guide with a rhombus shape in plan view is provided in a position where the inclination angle with respect to the ground is similar to the inclination angle with respect to the ground of the weed support rod. A tip guide is provided, and further, the second stock guide and the starting end of the tip guide are located near the starting end of the pulling device, and the inclination angle of the tip guide relative to the ground is set so that the angle of inclination relative to the ground of the second stock guide is dog than the angle of inclination, and
It is characterized in that the lifting device is arranged in a posture that approximates the angle of inclination to the ground of the lifting device.

This may cause the planted stem culm to be curved, or
Even if a planted stem culm is introduced to the lateral outer side of the planted stem culm introduction route due to meandering of the machine, the first stock source provided on the lateral outer side of the planted stem culm introduction route. By the guide
The base of the planted stem culm can be reliably and smoothly guided into the action area of the rotary scraping device.

Furthermore, even in the case of a short culm in which the engagement with the pulling device is completed before the culm introduced into the planted culm introduction path is moved into the action area of the rotary raking device, Both guides having a rhombic shape in plan view are provided between the two planted stem culm introduction paths, and the guide on the tip side has a large inclination angle with respect to the ground that is approximated by the inclination angle with respect to the ground of this pulling device. At the same time, the angle of inclination to the ground of the second plant base guide is made to have a gentle inclination angle similar to the inclination angle to the ground of the weeding support rod, so that the vertical distance between the ends of these guides is large, so that the stem This also prevents the culm from falling forward unexpectedly.

The entanglement of the left and right planted stem culms can be easily resolved by applying a relatively soft force to the stem culms without forcing them to separate, causing grain shedding or ear breakage, as if using a forced drive guidance device. Although the stem culm can be loosened, it is also possible to maintain a favorable standing posture from beginning to end by applying a combing action to the stem culm using these two guides, which have a relatively large angle difference, that is, the tip guide and the second plant base guide. At the same time, it can be reliably and well guided into the action area of the rotary scraping device.

Therefore, regardless of the introduction position of the planted stem culm introduced into the planted stem culm introduction path, the culm length of the planted stem culm, and the state of entanglement, the planted stem culm can be placed within the action area of the rotary raking device. certainty,
It can be guided smoothly and reliably performs the intended reaping work.
We were able to do it well.

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