Description

[Detailed description of the invention] The present invention has a device installed at the front of the device that clamps and conveys the cut grass toward the rear of the machine, for separating the planted grass immediately before harvesting from the planted grass that follows. This invention relates to a straw harvester in which a grass rod is provided so as to be rotatable back and forth when driven.

The straw grown in the field has a tendency to entangle more strongly than the stems of rice and wheat, and in order to have commercial value as a straw used for tatami mats, etc., it must be grown above a certain level. It must have a certain length, and it is not only necessary to simply harvest it, but after harvesting, it must be sorted into long culms and short culms.

Conventionally, as shown in Japanese Utility Model Publication No. 53-22524, such a rice grass harvester has been equipped with a vibrating weeding body that applies forced vibrations in the left and right direction to the planted rice grass before it is harvested. There was one that was configured to vibrate the grass that had been planted and then cut it.

With this configuration, since the vibration is simply given to the planted grass, the attempt to loosen the entanglement between the planted grass just before reaping and the planted grass that follows it by this means is limited to the direction of the vibration. It ended in failure because it was not rational and the means of vibration itself was not effective.

The present invention can effectively separate the planted grass immediately before reaping from the planted grass that follows it, that is, loosen the entanglements, effectively prevent breakage and tearing of the grass after reaping, and improve the efficiency of the next process. In addition to being able to perform processes such as pickling and sorting effectively, through extremely simple modification, the straw grass is fed to the clamping and conveying device in a way that minimizes damage to the grass depending on the degree of entanglement of the planted grass. The objective is to provide a rice straw harvesting machine that can be operated in a convenient manner.

In order to achieve the above object, the feature of the present invention is that the front part of the device that clamps and conveys the harvested straw grass toward the rear of the machine is attached intermittently to the row of planted straw grass just before harvesting as it oscillates. A reciprocating rotation axis substantially perpendicular to the conveying direction of the clamping and conveying device when viewed from the side is used to move the grass dividing rod that enters and retires from the grass row and separates the planted grass that is about to be harvested from the planted grass that follows. The branching rod is provided so as to be able to reciprocate around the reciprocating rotation axis, and the installation posture of the dividing rod with respect to the reciprocating rotation axis is set to be approximately parallel to the conveying direction of the clamping conveyance device, and with the free end side being more than the approximately parallel posture. The structure is configured so that it can be freely changed to an upwardly facing posture, and this structure provides the following effects.

In other words, the above-mentioned weeding rod repeatedly enters and retires intermittently into the row of grasses as it swings, so as the weeding rod enters the grass row, the area further forward in the direction of movement of the aircraft The grass that follows the planted grass that is about to be reaped, which is the grass that is being harvested, is temporarily stopped from moving backwards with respect to the aircraft, and during this time, the grass that is the grass that is planted immediately before it is being harvested, which is the grass that is on the rear side in the direction of travel, is moved by the movement of the aircraft. As a result of the retirement of the weeding rod from the grass side, the following grass grass that had been stopped on the forward side in the direction of movement will move rearward again. As a result, as the weeding rod swings, the grass is moved intermittently at intervals in the front and back of the transport direction.
In this way, by widening the distance between the roots in conjunction with the movement, the loosening of the tips is promoted, and when the dividing rod enters the row of grasses, it applies an impact to the base of the roots of the following grasses on the front side. By shaking the tip side, it is possible to obtain the effect of loosening the cut grass before reaping, and preventing entanglement between the planted grass just before reaping and the following grass.

Therefore, the tip side of the cut grass may become entangled with the following planted grass, and the tip side of the cut grass or the subsequent planted grass may be broken or torn off before or during transportation. It has been achieved that the grass can be harvested with less risk of causing any inconvenience that will impair the product value, and that it can also be effectively loosened from the entanglements of the rush that will lead to the next step, the pick-and-select device, making it easier to pick and sort. Ivy.

Moreover, if the leading edge of the grass that follows is strongly entangled with the planted grass just before harvesting, the posture of the dividing rod is changed to a rotational position that is directed upward from the conveying direction of the clamping and conveying device. By combing the trailing grass toward the tip side, the entanglement can be effectively eliminated, and when the entanglement is weak, the weeding rod is moved in the direction of conveyance of the holding and conveying device. By changing the posture to a nearly parallel rotational position, weeding can be done well without damaging the following rush grass due to unnecessary combing, and overall the extension of the weeding rod can be improved. By simply changing the posture, it has become possible to perform proper weeding according to the degree of entanglement of the following rushes.

Next, embodiments of the present invention will be described in detail based on the drawings.
