It is preferable that a space portion for passing at least one of wiring and piping for the equipment provided in the discharge conveyor is formed inside the conveyor support frame.
　本構成によれば、排出コンベアには、油圧式あるいは電気式の各種の駆動用の機器が備えられている。これらの機器に対して機体側から配線及び配管の少なくともいずれか一方を配策する必要がある。この配線や配管は、回動支点付近を通過するが、外部に大きく露出していると無理な折れ曲がりや他物との干渉等により損傷のおそれがある。 According to this configuration, the discharge conveyor is equipped with various hydraulic or electric drive devices. It is necessary to arrange at least one of wiring and piping from the aircraft side for these devices. These wirings and pipes pass near the rotation fulcrum, but if they are largely exposed to the outside, they may be damaged due to excessive bending or interference with other objects.
　そこで、コンベア支持フレームの内部に空間を形成することにより、配線及び配管の少なくともいずれか一方が空間を通ることで、外部への露出を少なくして損傷を防止することができる。 Therefore, by forming a space inside the conveyor support frame, at least one of the wiring and the piping passes through the space, so that the exposure to the outside can be reduced and damage can be prevented.

However, since such a work deck 22 has a large amount of protrusion to the laterally outward side of the machine body, it may become an obstacle when the machine body is transported by using a container, for example. Therefore, the portion protruding outward is configured to be removable.
　図８，図９に示すように、デッキ本体２２Ａに対して外側部２２Ｂが取り外し可能に構成されている。外側部２２Ｂは、デッキ本体２２Ａの載置台２４に連なる分割載置台２５と手摺２６とが一体的に連結されている。分割載置台２５の下部から延長形成された３つの取付部２７が、載置台２４の下側に設けられた被連結部２８にボルト連結することにより連結される構成となっている。ボルト連結を解除することで、外側部２２Ｂを取り外すことができる。 As shown in FIGS. 8 and 9, the outer portion 22B is configured to be removable with respect to the deck main body 22A. In the outer portion 22B, the split mounting table 25 connected to the mounting table 24 of the deck main body 22A and the handrail 26 are integrally connected. The three mounting portions 27 extended from the lower part of the split mounting table 25 are connected by bolting to the connected portion 28 provided on the lower side of the mounting table 24. The outer portion 22B can be removed by releasing the bolt connection.
