While sow liquid and make liquid sow vehicle 1 to travel in the situation that, liquid is sowed vehicle 1 when crop or barrier contact with 21 collisions of side swing arm, the second turning cylinder 51 of buffer gear 50 of take is center of rotation, and side swing arm 21 rotates (rear rotation) along the direction of the left and right sides of car body 2.Therefore, during collision or the impact that is applied on side swing arm 21 of when contact relaxed, the damage of side swing arm 21 is suppressed.In addition, side swing arm 21 can be avoided the amount of directly hitting the tensile force of corresponding draft helical spring 52.
In addition, even make liquid sow vehicle 1 to advance rapidly to sow posture, or make intermittently liquid sow vehicle 1 to advance to sow posture, or to sow posture, make liquid sow vehicle 1 to cross continuously under the operating condition of the harshnesses such as field and sow in the situation of liquid, liquid is sowed vehicle 1 and can be take the second turning cylinder 51 of buffer gear 50 and rearward rotate as center of rotation makes side swing arm 21.Therefore, the bending of side swing arm 21 (car body 2 is in the bending of fore-and-aft direction) is suppressed, and the breakage of side swing arm 21 is suppressed.
In addition, swing arm is opened and closed to cylinder 41 with the same inclination of turning cylinder 43, be arranged on support portion 44, it is not outstanding upward with respect to central swing arm 22 that swing arm opens and closes cylinder 41, therefore operator is easy to, from the atomize of the central swing arm 22 of driver seat 4 identification, can when confirming atomize, carry out operation.In addition, side swing arm 21 is because its cross section is that quadrangle shape or octagonal shape etc. are polygon-shaped, and its profile forms plane, can contact with each support portion 61b, the 71b face of each swing arm support 60,70.
In the situation that liquid sow end, by operator, operate liquid and supply with operating portion 82, liquid is sowed vehicle 1 and is stopped liquid sowing from each nozzle 21a, the 22a of each swing arm 21,22.Then, operator operates swing arm operating portion 81, by shrinking the swing arm of swing arm switching mechanism 40, opens and closes cylinder 41, liquid sow vehicle 1 make side swing arm 21 with respect to car body 2 low early and high after tilt, become the posture of taking in along the left and right sides of car body 2.Now, side swing arm 21 and limiting part 45 take in stance adjustment bolt 45b butt, to take in posture location.
Secondly, operator operates swing arm operating portion 81, by shrinking the swing arm lift cylinders 31 of swing arm elevating mechanism 30, thereby liquid sow vehicle 1 each swing arm 21,22 declined, side swing arm 21 is accommodated in each swing arm support 60,70.Now, due to the inclined plane of each support portion 61b, the 71b of each swing arm support 60,70 and side swing arm 21 below for face contacts, so side swing arm 21 is stably contained.
In addition, due to each support portion 61b, 71b with side swing arm 21 for face contacts, therefore when taking in side swing arm 21, suppressed with respect to the load of side swing arm 21 parts, suppressed the breakage of side swing arm 21.In addition, swing arm switching mechanism 40 is because the tangential direction that swing arm opens and closes on the flexible direction of cylinder 41 and the slewing circle centered by swing arm run-on point (take turning cylinder 43 as center of rotation) is almost orthogonal direction when taking in posture, therefore make swing arm open and close cylinder 41 when flexible with constant speed, accelerating taking near the peripheral speed on the slewing circle of swing arm run-on point posture.In addition, swing arm switching mechanism 40 is owing to accelerating taking near the velocity of rotation of side swing arm 21 posture, therefore makes side swing arm 21 when taking in posture, can make side swing arm 21 rapidly along the left and right sides of car body 2.
In addition, because operating portion 80 is configured in the right side of driver seat 4, therefore operator can be in the plant protection operation of carrying out the operation of each swing arm 21,22 and operation of sowing of liquid and so on the right hand, and the enough left hands of energy carry out the running operation of operation of steering wheel and so on.
In the situation that spray tank 10 is installed or removed from car body 2, at the existing liquid that swing arm support is fixed on main frame 3, sow in vehicle, in the installation of spray tank 10 with while taking off, swing arm support is taken off very time-consuming from main frame 3, but sow in vehicle 1 at the liquid of present embodiment, due to rear swing arm support 70 is arranged on to spray tank 10, so can spray tank 10 is arranged on to main frame 3 or take off the state of swing arm support 70 after be provided with.Therefore, liquid is sowed vehicle 1 and is easy to make spray tank 10 handling.
As mentioned above, according to the liquid of present embodiment, sow vehicle 1, due to low dip posture after high before turning cylinder 43 is formed, so flexible by making swing arm open and close cylinder 41, thereby with respect to the low early and high after inclination of car body 2, side swing arm 21 can be switched to along the left and right sides of car body 2 take in posture and along the left and right directions of car body 2, extend sow posture.That is, can open and close the flexible of cylinder 41 and side swing arm 21 is switched to and takes in posture or sow posture by swing arm.
Therefore, can side swing arm 21 be switched to and take in posture or sow posture with simple structure.That is, liquid is sowed vehicle 1 and can be switched to and take in posture or sow posture with an action.
In addition, according to the liquid of present embodiment, sow vehicle 1, the leading section that swing arm opens and closes cylinder 41 is installed on the rotor plate 42 rotating together with turning cylinder 43, make rotor plate 42 and turning cylinder 43 quadratures.Therefore, owing to take swing arm that the joint pin 44a of support portion 44 is center of rotation, to open and close the plane of rotation of cylinder 41 parallel with the plane of rotation of rotor plate 42, therefore expansion link 41c do not applied to unnecessary load, and the expansion link 41c that can make swing arm open and close cylinder 41 stretches swimmingly.
In addition, according to the liquid of present embodiment, sow vehicle 1, on side swing arm 21, to set interval, nozzle 21a is installed, make the angle of medical liquid spraying direction of the nozzle 21a of side swing arm 21 when taking in posture or almost parallel parallel with turning cylinder 43.Therefore, parallel in the situation that, in the posture of sowing of side swing arm 21, can be relatively and the liquid direction of advance of sowing vehicle 1 spray backward liquid.In addition, the in the situation that of almost parallel, in the posture of sowing of side swing arm 21, direction that can be identical to the nozzle 22a with central swing arm 22 is sprayed liquid.

(variation 3)
Secondly, with reference to Figure 10, the liquid of variation 3 is sowed to vehicle 1 and describe.Figure 10 is for illustrating that the liquid of variation 1 sows the key diagram of vehicle.It is larger that the liquid of variation 3 is sowed the angle of inclination of the angle of inclination of line that vehicle 1 makes to link the support portion 61b of front swing arm support 60 and the support portion 71b of the rear swing arm support 70 side swing arm 21 when taking in posture.
At the liquid of variation 3, sow in vehicle 1, the angle of inclination of the line A of the side swing arm 21 of the angle of inclination of line B that makes to link the support portion 61b of front swing arm support 60 and the support portion 71b of rear swing arm support 70 when representing to take in posture is larger.Rear swing arm support 70 outside is obliquely upward installed obliquely from the top of spray tank 10.In this variation 3, the arm 72 of rear swing arm support 70 is after extend in the outside of the left and right directions towards car body 2, then inclination obliquely laterally.Also have, in this variation 3 take in posture time refer to, by swing arm, open and close the flexible of cylinder 41, make side swing arm 21 with respect to car body 2 low early and high after tilt, make side swing arm 21 under the state of the left and right sides of car body 2, when the support portion 61b of the cradle portion 61 of side swing arm 21 and front swing arm support 60 is contactless state.In addition, in this variation 3, take in the posture that recovery refers to the former support portion 61b of swing arm support 60 and the support portion 71b support-side swing arm 21 of rear swing arm support 70.
The liquid of this variation 3 is sowed vehicle 1, side swing arm 21 is being switched to take in recovery in the situation that from sowing posture, swing arm operating portion 81 by operator's operating operation portion 80 shrinks swing arm and opens and closes cylinder 41, make side swing arm 21 with respect to car body 2 low early and high after tilt and along the left and right sides of car body 2.Then, by operator, operate swing arm operating portion 81 and shrink swing arm lift cylinders 31, thus liquid sow vehicle 1 side swing arm 21 declined, side swing arm 21 is received into the cradle portion 71 of rear swing arm support 70.Then, operator further falls side swing arm 21, side swing arm 21 is received into the cradle portion 61 of front swing arm support 60, stops the decline of side swing arm 21.Now, because the angle of inclination change of side swing arm 21 is large, at the reception position of taking in the side swing arm 21 under recovery, uprise, so operator is easy to boarding from driver seat 4.In addition, owing to applying the load of side swing arm 21 at rear swing arm support 70,21 bendings of side swing arm, therefore with respect to following liquid to sow the vibration of the above-below direction travelling of vehicle 1, the restoring force of opposing side swing arm 21, the spring of side swing arm 21 and vebrato etc. are suppressed, and liquid is sowed vehicle 1 can stably take in side swing arm 21.
(variation 4)
Secondly, with reference to Figure 11, the liquid of variation 4 is sowed to vehicle 1 and describe.Figure 11 is for illustrating that the liquid of variation 1 sows the key diagram of vehicle.The liquid of variation 4 is sowed the configuration that the variable swing arm of vehicle 1 opens and closes cylinder 41.
At the liquid of variation 4, sow in vehicle 1, in the configuration support portion, front side 44 of swing arm lifting linking member pillar 33, in rear side configuration the 2nd support portion 46 of swing arm lifting linking member pillar 33.In variation 4, swing arm opens and closes cylinder 41 and is installed in rotation on the 2nd support portion 46 by joint pin 46a.In addition, the leading section of the expansion link 41c of swing arm switching cylinder 41 is installed in rotation on rotor plate 42 by joint pin 42a.On rotor plate 42, side swing arm 21 sow posture time, an avris the longest in the distance of the center of rotation apart from turning cylinder 43 is provided with joint pin 42a.Also have, rotor plate 42 is diagram especially, can install joint pin 42a make side swing arm 21 sow posture time make cylinder operating point be positioned the roughly dead astern of turning cylinder 43.In this variation 4, rotor plate 42 is when swing arm opens and closes cylinder 41 elongation maximum, while taking in posture, cylinder operating point (joint pin 42a) is positioned the roughly positive of turning cylinder 43, when swing arm opens and closes cylinder 41 contraction maximum, while sowing posture, cylinder operating point is positioned the inside of basic point (joint pin 46a) and swing arm run-on point (center of rotation of turning cylinder 43).That is, cylinder operating point leaves the straight line that links basic point and swing arm run-on point when taking in posture, when sowing posture, approaches the straight line that links basic point and swing arm run-on point.Therefore, swing arm opens and closes the flexible direction of cylinder 41, the roughly the same direction approaching for the tangential direction on the slewing circle centered by the swing arm run-on point with by cylinder operating point when taking in posture, the roughly orthogonal direction leaving for the tangential direction on the slewing circle centered by the swing arm run-on point with by cylinder operating point when sowing posture.
At the liquid of variation 4, sow in vehicle 1, the tangential direction that swing arm opens and closes on the flexible direction of cylinder 41 and the slewing circle centered by swing arm run-on point (take turning cylinder 43 as center of rotation) is roughly equidirectional when taking in posture, when sowing posture, be roughly orthogonal direction, therefore, if it is flexible with constant speed to make swing arm open and close cylinder 41, sowing near posture, peripheral speed on the slewing circle of swing arm run-on point accelerates, taking near posture, the peripheral speed on the slewing circle of swing arm run-on point is slack-off.Therefore, sowing near posture, the velocity of rotation of side swing arm 21 accelerates, and is taking near posture, and the velocity of rotation of side swing arm 21 is slack-off.In addition, owing to sowing near posture, the velocity of rotation of side swing arm 21 accelerates, thereby can make side swing arm 21 avoiding obstacles rapidly.In addition, owing to taking near posture, the velocity of rotation of side swing arm 21 is slack-off, so suppress to approach the speed that is sitting in the operator on driver seat 4, can after operator occupies stably, carry out the operation of taking in of side swing arm 21.
In addition, by change swing arm, open and close the configuration of cylinder 41, thereby can switch near the velocity of rotation of taking in posture or sowing near the side swing arm 21 posture, therefore can select to be suitable for the velocity of rotation of the side swing arm 21 of operation purposes or object.
Also have, in the present embodiment, liquid is sowed vehicle 1 makes the outstanding quantitative change of the inner side guide part 61c of each swing arm support 60,70 and each inner side guide part 61c, the 71c of outside guide part 71a or each swing arm support 60,70 large, but also can for example make the outstanding quantitative change of the outside guide part 61a of front swing arm support 60 and the inner side guide part 71c of rear swing arm support 70 large.Like this, for side swing arm 21 take in posture (comprise and take in recovery), even if be subject to being accompanied by liquid, sow the vibration that vehicle 1 travels, also can suppress side swing arm 21 and come off in inner side and the outside of car body 2.
