Description

Description: [Industrial application] The present invention mainly relates to a stem-culm raising structure in a straw harvester, and more specifically, to a tip-proximity portion of a raising claw in a stem-culm raising device. The present invention relates to a stem culm raising structure of a harvester provided with a raising frame that extends along the raising direction and defines a raising region.

[Conventional technology]

In the stem culm raising structure, conventionally, as an example of a harvesting machine, for example, as disclosed in Japanese Utility Model Laid-Open No. 1-118624, in the forward position of the stem culm raising device, a curved stalk is swung around. However, there was one configured to loosen the entwined strawberries and guide the vegetation.

[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 eliminate the above-mentioned drawbacks without significantly increasing the complexity of the structure.

[Means for solving the problem]

The stem culm raising structure of the harvesting machine according to the present invention has a raising frame that extends along the raising direction in the vicinity of the tips of the raising claws in the stem raising device and that defines a raising frame that defines the raising region. The stem culm raising structure of the machine, the raising frame is formed into a hollow pipe shape, and is configured to send air into the frame from the upper end thereof,
At the lower end of the raising frame, there is formed an air blowout port that blows out air toward the upper side along the front of the raising action region by the stem-culm raising device.

[Work]

When the wind is blown up from the air outlet, even if the stem tip side of the strawberries that have fallen violently during the raising action is hanging downward, the stem tip side rises upward due to the blowing force of the wind. Being guided, there is less risk of damage during the pulling action.

〔The invention's effect〕

Therefore, according to the present invention, by effectively utilizing the raising frame conventionally arranged for partitioning the raising region, a long dedicated blower pipe can be provided without hindering the raising guide action of the stems. It has become possible to prevent damage to the stalks due to the pulling of the stems without complicating the structure such as attachment.
