Description

Description: TECHNICAL FIELD The present invention relates to a harvesting machine for combine harvesters, binders, etc., and a fixed receiving blade and a movable cutting blade in which fixed split blade bodies are arranged side by side at regular intervals. The present invention relates to a reaper and a reaper having a reaper having a carrier device for transferring stem culms cut by the reaper to a threshing device mounted on a machine body.

[Conventional technology]

A conventional harvesting machine of this type is, for example, an actual Kaihei 1
An all culm throw type combine shown in Japanese Patent Publication No. 109922 is known.

[Problems to be Solved by the Invention]

In the above-mentioned conventional technique, the planting stems are cut off while the planting stems are sent to the mowing section side by a rotating reel arranged on the upper part of the mowing device. This method works well when the planting culm at the time of mowing is in a state of facing upward or slightly lying down, but the planting culm is facing the aircraft, that is, in the cut state. In addition, if it is lying prominently along the ground, the rotary reel may not be able to raise the fall culm and it may become impossible to mow, and there is room for improvement. there were.

An object of the present invention is to realize a reaper harvesting machine that does not have the above inconvenience.

[Means for Solving the Problems]

In order to achieve the above object, the present invention is, in the cutting and harvesting machine described at the beginning, at the tip end portion of the divided blade body, provided with a blowout port capable of blowing out pressure blown by a blower, the blowout port is the blowout port. It is characterized by the fact that the pressure-fed air coming out of it is directed to the state of flowing backward and upward.

[Work]

According to the above-mentioned structure, (a) When the divided blade body is dipped under the planting culm that is lying toward the machine body, the tip of the divided blade body is lifted up by the blown air from the tip of the divided blade body. As a result, it is possible to cut even an upright culm that has fallen so far that it could not be cut well in the past.

Since (b) the blown air blown from the outlet is directed to the upper rear, it acts to blow the cut stalks after cutting to the rear, and between the cutting device and the auger in the cutting part of the all-cule throw type combine. It is also possible to omit the conveyor device for post-feeding the cut stalks.

Further, (c) since the means for raising the lodging stems according to the present invention uses wind force, there is no object for rubbing the stems, for example, a contact-type means for lifting the locking claws on the tips of the spikes. In comparison, the risk of damaging the stalks and the risk of grain shedding at the time of raising are reduced.

〔The invention's effect〕

Therefore, the action (a) eliminates the conventional inconvenience to improve the cutting performance, and the action (b) can simplify the structure of the cutting portion, and the action (c) can improve the cutting stem culm. It has become possible to provide a cutting harvester with high practical value that can reduce the adverse effects of cutting.
