耘機の後カバー構造に関する。[Detailed description of the invention] [Industrial field of application] The present invention provides a rear cover structure for a walk-behind tiller, more specifically, a rotary tiller device is connected to the rear of a self-propelled machine, and the rotary tiller of this rotary tiller The present invention relates to a rear cover structure for a walk-behind cultivator, in which a boss for attaching an attachment and a rotary cover are attached to the frame, and a rear cover is attached to the rear end of the rotary cover.

金製のカバーの使用が求められてきた。
A rubber sag is attached to the rear of the walk-behind cultivator as a rear cover to prevent soil scattered during tillage from getting on the legs of the working vehicle. However, in recent years, rubber tare has become insufficient to protect workers' feet from stones mixed in the soil that is scattered during plowing, or to prevent workers' feet from getting caught in the plowing rotary. This has been sufficient and the use of sheet metal covers has been sought instead.
しかし乍ら、後カバーを板金製にするとそれを

However, if the rear cover is made of sheet metal, the parts that support it must also have a strong structure.
However, although there is a rotary frame extending rearward and a rotary cover fixed to it, the strength is too weak for the rear cover to be supported only by the rotary cover, and a strong force is applied to the rear cover. There is a risk of deformation when it acts. Furthermore, there is no suitable mounting location for supporting the rotary frame, which has the disadvantage of requiring major design changes and increasing costs.
本考案は、上記実情に着目し、板金製の後カバ
ーを歩行型の耕耘機に簡単且つ強固に取付けられ

果は次の通りである。
The characteristic structure of the present invention that achieves the above object is that a rotary tiller is connected to the rear of the self-propelled vehicle, a rotary cover is attached to the rotary frame of the rotary tiller, and a rotary cover that covers the upper part of the rotor is attached.
A boss for attaching an attachment is provided at the rear end of the rotary frame, and the boss at the rear end of the rotary frame is provided with a connecting shaft for fitting into the boss and a mounting portion for a rear cover made of sheet metal that covers the rear part of the rotor. The connecting shaft of the rear cover mounting stay provided can be inserted, and the rear cover mounting stay and the rear end of the rotary cover can be fixed,
The rear cover made of sheet metal is pivotably mounted on the rear cover mounting stay, and its functions and effects are as follows.
つまり、板金製の後カバーを枢着する取付ステ
ーにかかる力は、取付ステーに突設された連結軸

に十分耐えることができる。
In other words, the force applied to the mounting stay that pivotally connects the rear cover made of sheet metal is received by the boss of the rotary frame via the connecting shaft protruding from the mounting stay, and is also distributed and supported by the rotary cover. Even if a large force is applied to the sheet metal rear cover, it can sufficiently withstand it.
従つて、強度の高い既存のアタツチメント取付
用ボスを利用した強固な後カバー取付けが可能な

特別な改造が必要ないから安価に実施できる。
Therefore, it is possible to mount the rear cover firmly using the existing high-strength attachment mounting boss, and it can be carried out at low cost since no special modifications to the rotary frame or rotary cover are required.
