Description

【考案の詳細な説明】 （産業上の利用分野） 本考案は、刈草集草装置に関する。[Detailed explanation of the idea] (Industrial application field) The present invention relates to a grass clippings collection device.

（従来の技術） モアーで刈取つた刈草を給送装置でシユートを

る。(Prior Art) As shown in Fig. 7, a grass collection device that collects grass by feeding grass clipped with a mower through a chute into a grass collection container has a pair of left and right grass collection containers each having an upper opening. 1 and 2 are disposed close to each other, and a chute 4 is provided above one of the grass collection containers 2 so that the opening 3 faces the boundary between the two containers.

（考案が解決しようとする課題） この種のものでは、シユート４の開口部３から
放出された刈草が両者集草容器１，２の境界部分
に落下するように開口部３を位置させ、各集草容
器１，２に均等に刈草が配分されるようにしてい
る。(Problem to be solved by the invention) In this type of device, the opening 3 is positioned so that the grass clippings discharged from the opening 3 of the chute 4 falls onto the boundary between the grass collection containers 1 and 2, and each The grass clippings are evenly distributed to the grass collection containers 1 and 2.

しかしながら、刈草の状態（湿つた刈草、乾燥

草で一杯になると、それによつてシユート４の開
口部３がふさがれ、集草効率が低下すると共に、
シユート４内に刈草のつまりが生じていた。 However, the flying distance of the grass clippings discharged from the opening 3 of the chute 4 varies depending on the condition of the grass clippings (wet grass clippings, dry grass clippings, etc.), so the grass clippings are not evenly distributed to the left and right grass collection containers 1 and 2. , the grass collection containers were often biased toward either one of the containers 1 and 2. In the case of dry grass clippings, most of the grass clippings are thrown into the other grass collection container 1, and when the other grass collection container 1 is full first, the grass clippings flow into the one grass collection container 2 side. In the case of ivy clippings, most of the grass clippings are put into one grass collection container 2, and when the one grass collection container 2 is full of grass clippings, the opening 3 of the chute 4 is blocked by the grass clippings, reducing the grass collection efficiency. As it decreases,
The chute 4 was clogged with grass clippings.

本考案は、湿つた刈草の場合に左右の集草容器
