Since the dust discharge direction from the dust discharge duct 45 is switched depending on the position, the dust discharge guide member 61 discharges the dust toward the lower left side of the transfer case 24 when the suction dust discharge box 35 is in the horizontal orientation. Even when the suction dust box 35 is in the standing posture, the amount of rotation of the dust guide member 61 is made larger than when the suction dust box 35 is in the horizontal posture, and the dust discharge direction is set downward.
Therefore, when dust is discharged from the transport case 24 and dust is collected above the reaping device 6 and around the control unit 5, the dust is guided to the lower left of the transport case 24 to improve the front view of the control unit 5.
Accordingly, the suction dust exhaust fan 33 in FIG. 12 is provided in the suction dust exhaust box 35 with its axis inclined to the left upward with respect to the top side 32 of the transport case 24, and the control unit 5 of the suction dust exhaust box 35. An inspection opening 70 is formed on the side, and a shutter 71 is detachably attached to the inspection opening 70. Therefore, when the shutter 71 is removed, the inspection opening 70 opens and the suction dust exhaust fan 33 is opened. Collects dust not only in the transport case 24 but also around the control unit 5 and discharges it to the left side of the transport case 24.

したがって、操縦部５周辺の塵埃除去を行え、操縦部５の前方視界を良好にする。
この場合、吸引排塵ボックス３５の操縦部５側の点検用開口部７０に加えて吸引排塵ボックス３５の刈取装置６側に前側点検用開口部７３を形成すると、シャッタ７４も外すことにより吸引排塵ファン３３は操縦部５周辺の塵埃の回収のみならず、刈取装置６上方周辺の塵埃を回収して除去を行える。
しかして、上記吸引排塵ファン３３の各実施例において、吸引排塵ファン３３を設けた吸引排塵ボックス３５には、作業灯７５を取付け、吸引排塵ボックス３５の操縦部５側の点検窓４１あるいはシャッタ７１を透明部材により形成し、点検窓４１あるいはシャッタ７１から作業灯７５の明かりが搬送ケース２４内に届くように構成しているので、夜間作業でも、操縦部５側から吸引排塵ボックス３５内および搬送ケース２４内を視認して、刈取作業を行える。
なお、前記した各実施例は、理解を容易にするために、個別または混在させて図示および説明しているが、これらの実施例は夫々種々組合せ可能であり、これらの表現によって、構成・作用等が限定されるものではなく、また、相乗効果を奏する場合も勿論存在する。 Therefore, the dust around the control unit 5 can be removed, and the front view of the control unit 5 is improved.
In this case, if the front inspection opening 73 is formed on the cutting device 6 side of the suction dusting box 35 in addition to the inspection opening 70 on the control unit 5 side of the suction dusting box 35, the suction is performed by removing the shutter 74. The dust exhaust fan 33 not only collects dust around the control unit 5 but also collects and removes dust around the cutting device 6.
Accordingly, in each of the embodiments of the suction dust exhaust fan 33, the work light 75 is attached to the suction dust exhaust box 35 provided with the suction dust exhaust fan 33, and the inspection window on the control unit 5 side of the suction dust exhaust box 35 is provided. 41 or the shutter 71 is formed of a transparent member, and the light of the work lamp 75 reaches the inside of the transport case 24 from the inspection window 41 or the shutter 71. The inside of the box 35 and the inside of the transport case 24 can be visually confirmed to perform the cutting operation.
Each of the above-described embodiments is illustrated and described separately or mixed for easy understanding. However, these embodiments can be combined in various ways, and these expressions can be used for configuration and operation. However, there is a case where a synergistic effect is obtained.
