する。[Detailed description of the invention] The present invention consists of an ear-side locking conveyance device and a stock-side clamping conveyance device, which are installed diagonally in the front-rear direction of the machine and are raised toward the end of the conveyance. Concerning a straw harvester that is transported to the rear of the aircraft in collaboration with

上記収穫機において、従来、穂先側係止搬送装
置として、無端回動帯状体に付設した爪を稈身に
係止させる型式が採用されていたため、稈身が点
状の極めて狭い面にて受止め支持されることにな
り、稈身が折れ易い欠点があつた。 In the above-mentioned harvesting machines, a type in which claws attached to an endless rotating band were locked to the culm was conventionally adopted as the ear-side locking and conveying device, so the culm was received on an extremely narrow dotted surface. The problem was that the culm was easily broken because it was supported by a stop.

るようにすることを目的とする。 The present invention improves the degree of lodging by modifying the tip-side locking and conveying device to one with a relatively large culm receiving surface that is less likely to cause culm breakage, and by adding modifications to the configuration for this purpose. To provide a product that can be reliably raised in a state in which culm breakage is less likely to occur even in the case of grasshoppers, while simplifying the structure.

うに構成した事を特徴とする。 In order to achieve the above object, the rush harvesting machine of the present invention includes a helical rotating body in which the tip side locking and conveying device is provided with a spiral band plate on the rotating shaft, and a spiral rotating body in which the tips of the conveyed rush grass are prevented from falling off. The front end of the spiral rotating body is located near the ground in front of the reaping device, and the spiral rotating body is tilted at a steeper inclination than the stock head side clamping and conveying device. The rear end of the helical rotating body is set at approximately the same height as the rear end of the stock side clamping and conveying device, and the rush head side is placed on the helical band plate of the spiral rotating body, and the helical base side clamping is carried out. It is characterized by being configured so that it is lifted up and transported rearward in cooperation with a transport device, and the culm changes its posture to a laid down position along the longitudinal direction of the aircraft.

本考案は以上の特徴構成を備えているので次の
作用効果を奏する。 Since the present invention has the above-mentioned features and configurations, it has the following effects.

イ 穂先側係止搬送装置を、回転軸に螺旋帯板を
付設した螺旋回転体で構成したから、稈身を従
来の係止爪よりも広い面で受止め支持でき、稈
身折れが生じにくくなつた。Since the tip-side locking and conveying device is composed of a spiral rotating body with a spiral band attached to the rotating shaft, the culm can be received and supported on a wider surface than conventional locking claws, making it difficult for the culm to break. Summer.

ロ 前記螺旋回転体を、先端が刈取装置の前方で
地面近くに位置するものにしたから、たとえ倒
伏の激しい藺草でも、その稈身を広い面で受止
め支持させながら強制引起しさせることが可能
になり、稈身折れを生じにくくしながら引起し
を確実に行える。(b) Since the tip of the spiral rotating body is positioned close to the ground in front of the reaping device, even if the grass is heavily lodging, it is possible to forcibly raise the culm while receiving and supporting it on a wide surface. This allows for reliable lifting while preventing the culm from breaking.

ハ 引起し装置と、後方への搬送装置とを別に設
ける構成に比べて、駆動系を簡単にできるとと
もに、刈取藺草の姿勢変更を円滑にでき、全体
として、倒伏度の大小いかんにかかわらず、稈
身折れの少ない品質のよい状態で能率よく収穫
できるものを安価に得ることが可能になつた。C. Compared to a configuration in which the lifting device and the rear conveyance device are provided separately, the drive system is simpler, the posture of the harvested straw can be changed smoothly, and overall, regardless of the degree of lodging, It has become possible to obtain products that can be efficiently harvested in a good quality state with less culm breakage at a low cost.
