さらに、図10、図11に示す如く、一対の略平行な固定板(68)(68)並びに一対の略平行な可動板(69)(69)で形成する刈取昇降ブラケット(70)を備え、前記メインビーム(34)中間の受台(71)に固定板(68)を一体固定させ、固定板(68)及び可動板(69)の傾斜上端側を固定ピン(72)によって回転自在に連結させると共に、前記トラックフレーム(1)に支軸(73)を介して昇降シリンダ(11)を連結させ、該シリンダ(11)のピストンロッド(74)先端を可動板(69)中間部にピン(75)を介して連結させ、可動板(69)の開孔(76)を介してピン(75)をピストンロッド(74)に着脱自在に貫挿させ、可動板(69)にピン(75)をボルト(77)止め固定させる一方、固定板(68)及び可動板(69)の傾斜下端側の開孔(78)(79)にピン(80)を着脱自在に貫挿させ、固定板(68)に前記ピン(80)をボルト(81)止め固定させるもので、図11の如く、固定板(68)と可動板(69)を千鳥状に交互に配列させ、メインビーム(34)の右側下面にブラケット(70)を設け、メインビーム(34)に対して昇降シリンダ(11)を機体右寄りに配設し、刈取部(8)重心位置を通過する前後方向中心線上に昇降シリンダ(11)を取付け、平面視でメインビーム(34)と刈取入力プーリ(37)の間に昇降シリンダ(11)を位置させ、刈取ベルト(40)に対してメインビーム(34)を離反させ、かつ昇降シリンダ(11)によって刈取部(8)重心位置を支えるように構成している。 Further, as shown in FIGS. 10 and 11, a mowing lifting bracket (70) formed by a pair of substantially parallel fixed plates (68) (68) and a pair of substantially parallel movable plates (69) (69) is provided. A fixed plate (68) is integrally fixed to a receiving base (71) in the middle of the main beam (34), and the upper ends of the fixed plate (68) and the movable plate (69) are rotatably connected by fixed pins (72). At the same time, an elevating cylinder (11) is connected to the track frame (1) via a support shaft (73), and a tip of a piston rod (74) of the cylinder (11) is pinned to an intermediate portion of the movable plate (69). 75), the pin (75) is removably inserted into the piston rod (74) through the opening (76) of the movable plate (69), and the pin (75) is inserted into the movable plate (69). The bolt (77) A pin (80) is removably inserted into the opening (78) (79) on the inclined lower end side of the fixed plate (68) and the movable plate (69), and the pin (80) is bolted to the fixed plate (68). (81) Stop and fix, as shown in FIG. 11, fixed plates (68) and movable plates (69) are alternately arranged in a staggered manner, and a bracket (70) is provided on the lower surface on the right side of the main beam (34). The lifting cylinder (11) is disposed to the right of the fuselage with respect to the main beam (34), and the lifting cylinder (11) is mounted on the center line in the front-rear direction passing through the position of the center of gravity of the reaper (8). The lifting cylinder (11) is positioned between the cutting input pulley (37) and the cutting input pulley (37), the main beam (34) is separated from the cutting belt (40), and the cutting unit (8) is moved by the lifting cylinder (11). Structure to support the center of gravity It is.
