（技術的意義）
上記作業車両の構成について、その技術的意義をまとめると、以下のとおりである。
(Technical significance)
The technical significance of the construction of the work vehicle is summarized as follows.
上記構成の作業車両は、圃場走行可能に支持したメインフレーム３にフロアステップ４を備えるとともに、伝達軸によって走行連動動作可能に施肥装置を備えて構成され、前記施肥装置は、フロアステップ４の左右に配置した２つの施肥ブロック７，７によって構成し、これら左右の施肥ブロック７，７を支持する左右の施肥フレーム８，８をメインフレーム３から左右に張出すとともに、左右の施肥フレーム８，８の前側をそれぞれ固定する左右のフロントフレーム３ａ，３ａをメインフレーム３に設ける。 The work vehicle having the above configuration includes a floor step 4 on the main frame 3 that is supported so as to be able to travel on the field, and is provided with a fertilizer that can be operated in conjunction with a transmission shaft. The left and right fertilization frames 8, 8 that support the left and right fertilization blocks 7, 7 project from the main frame 3 to the left and right, and the left and right fertilization frames 8, 8. Left and right front frames 3a and 3a for fixing the front sides of the main frame 3 are provided.
このように、機体の左右両側に施肥フレーム８，８により、施肥ブロック７，７をメインフレーム３の左右に配置することができ、左右のフロントフレーム３ａ，３ａによってメインフレーム３に左右の施肥フレーム８，８をそれぞれ固定することで耐久性向上が図れる。
また、施肥ブロック７，７を走行車体の左右両側に設けることにより作業スペースが広くなり作業性が向上し、走行車体のバランス性も向上する。
In this way, the fertilizer blocks 7 and 7 can be arranged on the left and right of the main frame 3 by the fertilizer frames 8 and 8 on the left and right sides of the machine body, and the left and right fertilizer frames are attached to the main frame 3 by the left and right front frames 3a and 3a. Durability can be improved by fixing 8 and 8 respectively.
Further, by providing the fertilizer blocks 7 and 7 on both the left and right sides of the traveling vehicle body, the work space is widened and the workability is improved, and the balance of the traveling vehicle body is also improved.
次に、前記伝達軸は、施肥作動量を調節する施肥量調節部１３を介して左右の施肥ブロック７，７の一方に施肥動力を伝達する第一伝達軸１２と、左右の施肥ブロック７，７間で施肥動力を伝達する第二伝達軸１４とによって構成し、これら第一伝達軸１２および第二伝達軸１４をフロアステップ４および左右の施肥ブロック７，７の下方に配置する。 Next, the transmission shaft includes a first transmission shaft 12 that transmits fertilization power to one of the left and right fertilization blocks 7 and 7 via a fertilization amount adjustment unit 13 that adjusts the fertilization operation amount, and the left and right fertilization blocks 7, The first transmission shaft 12 and the second transmission shaft 14 are arranged below the floor step 4 and the left and right fertilization blocks 7 and 7.
このように、第一伝達軸１２から施肥量調節部１３によって施肥量調節可能に施肥動力が一方の施肥ブロック７に伝達されるとともに、第二伝達軸１４を介して他方の施肥ブロック７に伝達され、また、伝達構成部材である第一伝達軸１２、施肥量調節部１３、第二伝達軸１４がフロアステップ４と左右の施肥ブロック７，７の下方に配置されることで、フロアステップ４と施肥ブロック７，７が伝動系のガードの役割をはたし、安全性が向上する。またフロアステップ４上の作業スペースを妨げない。 In this way, fertilization power is transmitted from the first transmission shaft 12 to one fertilization block 7 so that the fertilization amount can be adjusted by the fertilization amount adjustment unit 13, and transmitted to the other fertilization block 7 via the second transmission shaft 14. In addition, the first transmission shaft 12, the fertilization amount adjusting unit 13, and the second transmission shaft 14, which are transmission components, are arranged below the floor step 4 and the left and right fertilization blocks 7 and 7, so that the floor step 4 And the fertilization blocks 7 and 7 play the role of the guard of a transmission system, and safety improves. Moreover, the work space on the floor step 4 is not disturbed.
また、前記作業車両は、メインフレーム３の走行支持部から走行動力を分岐する伝動ケース１１を設け、この伝動ケース１１と第一伝達軸１２とを連結する第一調整ロッド１１ａと、第二伝達軸１４と左右の施肥ブロック７，７とをそれぞれ連結する左右の第二調整ロッド１４ｂ，１４ｂとを設け、これら調整ロッド１１ａ，１４ｂを長さ調節可能に構成する。 In addition, the work vehicle includes a transmission case 11 that branches the traveling power from the traveling support portion of the main frame 3, a first adjustment rod 11 a that connects the transmission case 11 and the first transmission shaft 12, and a second transmission. Left and right second adjustment rods 14b and 14b for connecting the shaft 14 and the left and right fertilization blocks 7 and 7 are provided, and the adjustment rods 11a and 14b are configured to be adjustable in length.
このように、３箇所に設けた長さ調節可能な調整ロッドにより、最小限構成で左右の施肥ブロック７，７の繰り出し量を調整できるので、効率よくメンテナンスが可能となる。 Thus, the adjustment rods that can be adjusted in length at three locations can adjust the feeding amounts of the left and right fertilization blocks 7 and 7 with a minimum configuration, so that maintenance can be performed efficiently.
また、前記作業車両は、左右の施肥フレーム８，８の後部をそれぞれ固定するリアフレーム３ｂ，３ｂをメインフレーム３の左右に設けてそれぞれ第二伝達軸１４の支点１４ａ，１４ａを設け、施肥量調節部１３の支点について、同一側の第二伝達軸１４の支点１４ａとの中間位置で施肥フレーム８とリアフレーム３ｂとを接続する。 Further, the work vehicle is provided with rear frames 3b, 3b for fixing the rear portions of the left and right fertilization frames 8, 8, respectively, on the left and right of the main frame 3 and provided with fulcrums 14a, 14a of the second transmission shaft 14, respectively. About the fulcrum of the adjustment part 13, the fertilization frame 8 and the rear frame 3b are connected in the intermediate position with the fulcrum 14a of the 2nd transmission shaft 14 of the same side.
このように、施肥量調節部１３の支点について、同一側の第二伝達軸１４の支点１４ａとの中間位置で施肥フレーム８，８とリアフレーム３ｂとを接続することで、機体差によるバラツキを減らすことができ、余分な伝達軸や長さ調節機構を設ける必要がないため、
コストを削減できる。
In this way, with respect to the fulcrum of the fertilizer application amount adjustment unit 13, by connecting the fertilizer frames 8, 8 and the rear frame 3b at an intermediate position with the fulcrum 14a of the second transmission shaft 14 on the same side, variations due to machine differences can be avoided. Since there is no need to provide an extra transmission shaft or length adjustment mechanism,
Cost can be reduced.
また、前記作業車両は、左右の施肥ブロック７，７にその機体内側位置から搬送エアを供給する左右の送風ダクト２２，２２と、残留肥料を機体外側位置に排出する左右の残量排出ダクト２３，２３とを設け、これら左右の残量排出ダクト２３，２３に開閉可能な排出口２３ａ，２３ａをそれぞれ備える。 The work vehicle also includes left and right blow ducts 22 and 22 for supplying conveyance air from left and right positions to the left and right fertilization blocks 7 and 7 and left and right remaining amount discharge ducts 23 for discharging residual fertilizer to a position outside the fuselage. , 23, and left and right remaining discharge ducts 23, 23 are provided with discharge ports 23a, 23a, which can be opened and closed, respectively.
このように、送風ダクト２２，２２が機体内側に、残量排出ダクト２３，２３が機体外側であることにより、左右の排出口２３ａ，２３ａを開くことで機体外側から肥料の排出作業を行えるので作業能率が良い。
また、肥料の排出を左右別々にすることで、肥料排出の際に、残量肥料を１つに集めるダクトやエア方向を切り替える必要がない。また、エア方向切換部品等が不要になり安価に構成できる。
As described above, since the air ducts 22 and 22 are inside the machine body and the remaining amount discharge ducts 23 and 23 are outside the machine body, the left and right discharge ports 23a and 23a can be opened so that the fertilizer can be discharged from the outside of the machine body. Good work efficiency.
Further, by separating the discharge of the fertilizer on the left and right, it is not necessary to switch the duct and the air direction for collecting the remaining fertilizer into one when discharging the fertilizer. In addition, air direction switching parts and the like are not required and can be configured at low cost.
また、前記作業車両は、左右の送風ダクト２２，２２を連通するエアチャンバ２２ａをフロアステップ４の後縁に沿って設け、このエアチャンバ２２ａの左右の屈曲部２２ｂ，２２ｂから左右の残量排出ダクト２３，２３を前下がりにそれぞれ支持して前端を排出口２３ａ，２３ａとする。 In addition, the work vehicle is provided with an air chamber 22a communicating with the left and right air ducts 22 and 22 along the rear edge of the floor step 4, and left and right remaining amount discharge from the left and right bent portions 22b and 22b of the air chamber 22a. The ducts 23 and 23 are supported in the front-down direction, and the front ends are defined as discharge ports 23a and 23a.
このように、左右外側の残量排出ダクト２３，２３を排出口２３ａ，２３ａまで前下がりに支持することで、残留肥料を自重で落ちやすくして排出スピードが向上し、且つ少ないエアでも排出できる。また、雨水の侵入を防ぎ水や肥料が貯まらないためメンテナンス性が向上する。 In this way, by supporting the remaining discharge ducts 23, 23 on the left and right outer sides forward to the discharge ports 23a, 23a, the residual fertilizer can be easily dropped by its own weight, the discharge speed is improved, and even less air can be discharged. . In addition, maintenance is improved because water and fertilizer are not stored, preventing rainwater from entering.
