For residual stalk treating apparatus C is risen, control hydraulic cylinder 91 interior hydraulic pressure so that guide body 93 moves to the body upper side.So the tensioning path of cable wire 92 is to body upper side change, the cable wire 92 of residual stalk treating apparatus C side is rolled-up, residual stalk treating apparatus C(homework department) rise and move to accommodated position.For residual stalk treating apparatus C is descended, control hydraulic cylinder 91 interior hydraulic pressure so that guide body 93 moves to the body lower side.So move to the body lower side in the tensioning path of cable wire 92, the cable wire 92 of residual stalk treating apparatus C side is released, residual stalk treating apparatus C(homework department) utilize deadweight to descend and move to job position.In addition, because cable wire 92 is turned back in the upper end of guide body 93 and is positioned at the left and right sides of hydraulic cylinder 91 and cable wire 92, therefore, the displacement on the body above-below direction of residual stalk treating apparatus C is 2 times of strokes of the displacement on the body above-below direction of cable wire 92.
In the field, exist under the bigger concavo-convex such situation of difference in height, if the residual stalk treating apparatus C's in the grain header is certain to ground level, then might cause the bottom surface of residual stalk treating apparatus C and the protuberance in field to collide and damage rotocycle 82.For fear of producing such unfavorable condition, at the rear of front vehicle wheel 1 and be in the position in residual stalk treating apparatus C the place ahead, be provided with the height sensor over the ground 95 to the situation of change of ground level that detects body, according to the detected value of height sensor 95 over the ground, switch the control valve that hydraulic pressure that subtend hydraulic cylinder 91 carries is controlled.That is, based on the situation of change to ground level of body, control residual stalk treating apparatus C to ground level.
For example, residual stalk treating apparatus C's controls ground level is following.
If reached more than the setting to subaerial direction from initial value by height sensor 95 detected variations to ground level over the ground, then switch hydraulic control valve so that move to the body upper side upper end of hydraulic cylinder 91, thereby residual stalk treating apparatus C is risen.In contrast, if reached more than the setting to the direction away from ground from initial value by height sensor 95 detected variations to ground level over the ground, then switch hydraulic control valve so that move to the body lower side upper end of hydraulic cylinder 91, thereby residual stalk treating apparatus C is descended.
Thus, concavo-convex with respect to ground can make the rotocycle 82 position rotation of side on the ground of residual stalk treating apparatus C.Consequently, can suppress rotocycle 82 and be subjected to effect from the load on ground, thereby can improve the durability of rotocycle 82.In addition, by at the rear of front vehicle wheel 1 and the position configuration that is in residual stalk treating apparatus C the place ahead height sensor 95 over the ground, height sensor 95 is difficult to be subjected to the influence of residual stalk over the ground.In addition, over the ground height sensor 95 be separately positioned on body about, thereby can improve the accuracy of detection to the variation of ground level of body.
In addition, because the lateral shaft core around body swings up and down swing arm 80a, the 80b that supporting freely is connected with the both ends of the length direction of residual stalk treating apparatus C, therefore, residual stalk treating apparatus C is supported at the both ends of length direction, makes the attitude stabilization of residual stalk treating apparatus C.Thus, the height that can carry out residual stalk treating apparatus C under the attitude that makes residual stalk treating apparatus C stable status is regulated.
In the present embodiment, being output shaft 180b from the lateral shaft core of body is configured to the distance of the other end 92b of cable wire 92, than the distance of the end of the residual stalk treating apparatus C side to swing arm 80a, 80b from output shaft 180b.Under the situation that the distance of the other end 92b to cable wire 92 from output shaft 180b is lacked to the distance of the end of the residual stalk treating apparatus C side of swing arm 80a, 80b than the output shaft 180b from body, the distance of the application point from output shaft 180b to cable wire 92 is shorter than the distance of the application point to swing arm 80a, 80b from output shaft 180b.On the other hand, as present embodiment, if will be from output shaft 180b the distance of the other end 92b to cable wire 92 be configured to distance than the end of the residual stalk treating apparatus C side to swing arm 80a, 80b from output shaft 180b, then from output shaft 180b the distance of the application point to cable wire 92 than the distance of the application point to cable wire 92 from output shaft 180b.
Like this, as if the distance of the application point to cable wire 92 from output shaft 180b, then can reduce to make residual stalk treating apparatus C around output shaft 180b swing locomotivity required, that cable wire 92 moves up and down.Thus, even if the driving force of the hydraulic cylinder (executing agency) 91 that reduces guide body 93 is moved also can be carried out the height of residual stalk treating apparatus C and be regulated, this guide body 93 makes the tensioning path movement of cable wire 92.Consequently, the miniaturization of hydraulic cylinder 91 can be sought, and the height adjusting structure of residual stalk treating apparatus C can be constituted compactly.
