DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a sward that is provided in front of a stem-and-culm raising device with a rotating sward body that divides a planted sward and forcibly shunts by rotational vibration. Regarding harvesters.

[Conventional technology]

In the above-mentioned stem culm raising structure, conventionally, for example, as disclosed in Japanese Utility Model Laid-Open No. 1-118624, at the front position of the stem culm raising device, a straw-shaped grass that is strongly entwined while swirling a curved shaped weeding rod is used. There was one configured to loosen and guide the grass.

[Problems to be Solved by the Invention]

The conventional structure is long and slender, and when the densely populated planting strawberries are in a state of being strongly intertwined with each other, a smooth bud raising effect can be obtained only by the raising action of the raising claws in the stem and culm raising device. Not done, damage to the culm, or
Since there is a risk of tearing off, before the action of raising the stem culm raising device, the branching rod is forced to divide the strawberries entwined by the rotation vibration of the branching rod from the root portion of the strawberries. It is a thing.

According to the above conventional structure, the entanglement in the left-right direction between the cut culm and the uncut culm is relatively smoothly disentangled, but, for example, when the planting strawberries are prone to lodge,
The tip side of the stem hangs downward and is forced to be pulled by the nails, which may damage or tear the stem culm, leaving room for improvement. It was

An object of the present invention is to solve the above-mentioned problems by a rational structure improvement.

[Means for solving the problem]

The strawberry harvester according to the present invention is, in a front position of the stem culm raising device, a turf harvester equipped with a rotating vegetation body forcibly cultivating by rotary vibration by dividing into the planted turf grass, in the stalk culm raising device. In the front lower part of the raising action site, while forming a blowing port for blowing and blowing air to the stem tip side of the straw grass to be raised, the raising path in the front side of the raising case in the stem culm raising device A characteristic configuration is that an inclined guide surface is formed so as to be located further toward the side.

[Work]

Even if the planted strawberries are intertwined with each other violently, and even if they are lying, they are forcibly distributed by the rotational vibration of the rotating buds prior to the raising action by the stem culm raising device, By being mechanically loosened, by supplying the blowing air from the blower outlet,
The tip of the stalk is smoothly guided upward so that no excessive force is applied to the stem culm during the raising operation.

Moreover, by providing the inclined guide surface that is located on the front side of the raising case and is located rearward toward the path side, the wind blown from below does not disperse in the left and right directions, but effectively acts on the tip of the stem. In addition, the tip portion of the stem that is being raised is guided toward the path side of the raised body as the machine body advances.

〔The invention's effect〕

Therefore, according to the present invention, the stem culm prior to the raising action can be brought into the standing posture by the blowing wind, and therefore the stem tip portion hangs down during the raising action and bends while applying an unreasonable force to raise. It is possible to prevent the harmful effects and prevent the damage of strawberries.

In addition, the sloping guide surface on the front side of the raising case allows the standing wind to effectively act on the stalk tip without hindering the progress of the airframe due to the rational structural improvement, and the stalk tip raising There is also an advantage that it can be smoothly introduced into the path.
