Further, a scraper 29 for protecting the culm from entanglement is placed only at a part of the front end of the outer periphery of the grass-dividing rotary body 21.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a stem culm raising device at the front part of a machine body, and from the rear part of the weeding tool fixedly arranged at the lower part of the front end of the machine body at the front position of the raising device, the raising device The present invention relates to a vegetative structure of a strawberries harvester in which a vegetation rotating body that is driven to rotate around an oblique axis toward the top is arranged.

[0002]

2. Description of the Related Art In the above weeding structure, conventionally, as disclosed in, for example, Japanese Patent Application Laid-Open No. 61-21021, the weeding rotator is composed of a bar material formed into a curved shape. There has been a structure in which both ends of the weeding rotor are supported and are driven to revolve at high speed.

[0003]

SUMMARY OF THE INVENTION The above conventional structure takes into consideration that strawberries that are strongly entwined with each other are smoothly forcibly divided by the rotator. However, as described above, the structure that weeds curved bar materials while swirling at high speed causes large vibrations, which is transmitted to the operating part of the aircraft and deteriorates the work environment, or is transmitted to peripheral equipment and adversely affected. Was sometimes caused. In addition, there are also drawbacks that the stuffed grass is wrapped around the end of the rotator of the weeds having a small revolution radius, and the stuffed grass is torn and damaged, or the rotation is hindered. Moreover, since the structure is such that a thin rod is swung around at high speed, it has a bad effect that it collides with a strong force against strawberries, causing a large number of breaks and degrading the quality. An object of the present invention is to eliminate the above-mentioned inconveniences by making a reasonable improvement.

[0004]

The feature of the present invention is that in the weeding structure of the strawberries harvester described at the beginning, the weeding rotor has a non-circular cross-sectional shape and a smooth outer peripheral portion. It is composed of a rod shaped to have a curved surface, and is configured to be driven to rotate around an axis at the center position of its non-circular cross section. The point is that a wrap-around scraper is provided in close proximity.

[Operation] The rotator of the vegetation rotates at its root part while applying rotation to the entangled strawberries in a tangled state by vibrating due to the difference in the distance from the center of rotation to the outer periphery in the circumferential direction. From then on, gradually divide upwards and divide. Moreover, since the above-mentioned vibration action is performed over substantially the entire length, even when the strawberries are about to be wound, the winding can be effectively prevented. Also, for example, even if foreign matter such as dust and weeds wetted by rain or morning dew tries to wind around the hay starting end side of the rotator, the scraper effectively scrapes it and prevents the winding. It continues to divide and divide as it did.

[Effect] As a result, it becomes possible to divide and divide the grass with less winding and breakage, as compared with the case where a thin rod is distributed at high speed while colliding against the straw grass. Further, in order to perform the same action as the above action, a structure in which the scraper is closely arranged over substantially the entire length of the outer periphery of the weed rotator is conceivable. The structure is such that the thin plate-shaped scraper extends long along the body, which has the drawback that vibration noise increases due to collisions with straw grass, etc. Also, the gap between the scraper and the outer circumference of the swarding rotor is narrow due to rotational movement. The state and the wide state are alternately repeated, and there is a drawback that there is a great risk that a hand will be caught in the above-mentioned gap at the time of the work of removing the wrapped waste straw, but in the present invention, the foreign matter is included. Since the scraper is provided only on a part of the front end side where there are many parts, it is possible to effectively prevent the winding of foreign matters, suppress the generation of vibration noise, and secure the safety in maintenance work. Having.
