本発明は、播種するための播種機、施肥するための施肥機、農薬等の薬剤を播くための施薬機、苗を植え付けるための移植機、等といった農用作業機に関し、より詳細には、作溝装置、配置装置、および覆土装置を備え、作溝装置により圃場に溝を形成し、該溝に被農作業対象物を配置装置により配置し、そしてその配置された被農作業対象物の少なくとも一部分を覆土装置で覆土するように構成された農用作業機の覆土機構に関する。   The present invention relates to an agricultural working machine such as a sowing machine for sowing, a fertilizer machine for fertilizing, a drug application machine for sowing chemicals such as agricultural chemicals, a transplanting machine for planting seedlings, and the like. A groove device, a placement device, and a soil covering device are provided, a groove is formed in the field by the groove production device, a farm work object is placed in the groove by the placement device, and at least a part of the placed farm work object is disposed The present invention relates to a soil covering mechanism of an agricultural working machine configured to cover with a soil covering device.

例えば、トラクター等の車両の後部に装着され、当該車両に牽引されながら、上記作溝装置である作溝ディスクにより圃場に溝を形成し、該溝に上記被農作業対象物である種子を上記配置装置である播種装置により播き、そしてその播かれた種子を覆土装置で覆土した後、その覆土した土を鎮圧装置で鎮圧するように構成された播種機は、農用作業機の一例として、従来から知られ且つ用いられている。   For example, a groove is formed in a field by a groove forming disk, which is the groove forming device, while being attached to the rear portion of a vehicle such as a tractor, and the seeds that are the farm work target are disposed in the groove. A sowing machine configured to sow with a sowing device, and soak the seed soaked with a soil covering device, and then suppress the covered soil with a pressure reducing device, has been conventionally used as an example of an agricultural work machine. Known and used.

特に、トラクター等の車両に牽引されながら播種を行なう播種機能だけでなく同時に施肥も行なう施肥機能も有する播種機は、一般に『施肥播種機』と呼ばれ(例えば、特許文献1参照)、播種機の一例として従来から知られている。尚、この施肥播種機の場合、上記被農作業対象物に相当するものが種子および肥料であることは言うまでもない。   In particular, a sowing machine having not only a sowing function for sowing while being pulled by a vehicle such as a tractor but also a fertilizing function for performing fertilization at the same time is generally called a “fertilizing sowing machine” (see, for example, Patent Document 1). Conventionally known as an example. Needless to say, in the case of this fertilizer seeder, seeds and fertilizers correspond to the above-mentioned farm work target.

従来の農用作業機の覆土装置は、農用作業機の本体であるディスクフレーム(『ローラーフレーム』とも称される。)に揺動自在に支持された覆土アームと、当該覆土アームの自由端に回転自在に取り付けられ、農用作業機の進行方向と交差するように所定の傾斜角度を持って延長する覆土ディスクと、当該覆土ディスクの圃場に対する加圧力を調節するためにディスクフレームと覆土アームとに架設された圧縮バネ機構と、を備えている。   A conventional soil covering device for an agricultural work machine is a cover arm that is swingably supported by a disk frame (also referred to as a “roller frame”) that is a main body of the agricultural work machine, and rotates to a free end of the soil covering arm. Covering disk that is freely attached and extends at a predetermined inclination angle so as to intersect the traveling direction of the agricultural work machine, and is installed on the disk frame and the covering arm to adjust the pressure applied to the field of the covering disk A compression spring mechanism.

このように構成された農用作業機の覆土装置によれば、覆土アームと圧縮バネ機構の協働により覆土ディスクが圃場の凸凹面に追随するように上下動自在となっているが、圃場の土質状態に応じて覆土量(即ち、覆土ディスクにより、種子、肥料、等に被せられる土の量)を調節するには、圃場に対する覆土ディスクの加圧力が所望の加圧力となるように覆土アームに対する圧縮バネ機構の付勢力の調節を行なう。
特開2003−125611号公報(段落[0008]〜段落[0011]、図1)
According to the soil covering device of the agricultural working machine configured as described above, the soil covering disk is movable up and down so that the soil covering disk follows the uneven surface of the field by the cooperation of the soil covering arm and the compression spring mechanism. In order to adjust the amount of soil covering (that is, the amount of soil covered with seeds, fertilizer, etc. by the soil covering disk) according to the state, the pressure on the soil covering arm is adjusted so that the applied pressure of the soil covering disk to the field becomes a desired pressure. Adjust the biasing force of the compression spring mechanism.
JP 2003-125611 A (paragraph [0008] to paragraph [0011], FIG. 1)

しかしながら、圧縮バネ機構の調節のみでは覆土量の調節範囲が狭く、特に覆土量を十分増加させることが困難であった。そのため、例えば耕起されていない圃場等といった覆土量が減少し易い土質状態の圃場においても十分な覆土量が得られるように調節可能な農用作業機の登場(より詳細には農用作業機に装着可能な覆土装置の登場)が望まれている。   However, the adjustment range of the soil covering amount is narrow only by adjusting the compression spring mechanism, and it is particularly difficult to sufficiently increase the soil covering amount. For this reason, for example, an agricultural work machine that can be adjusted so that a sufficient amount of soil covering can be obtained even in a soil-like field where the amount of soil covering tends to decrease, such as an uncultivated field, etc. The appearance of a possible earth covering device) is desired.

A rod-like member 32 having a circular cross section shown in FIG. 7 can be inserted into the main body 31a and can be held by a screw 31c. The internal space through which the bar-shaped member 32 of the main body 31a of the bar-shaped member holding mechanism 31 is inserted extends in a direction intersecting with the axis of the main body 17 of the fertilizer seeding machine 1 (in other words, a direction intersecting with the arrow A direction in FIG. 2). is doing. The disk position angle adjusting mechanism 39 described above is a general term for the rod-shaped member holding mechanism 31, the rod-shaped member 32, and the like.

棒状部材32は、覆土ディスク21が取り付けられる覆土アーム20の自由端部に相当する一端部32aを有し、そして棒状部材保持機構31の本体31aに挿通され且つネジ31cにより本体31aの内周面に押し付けられることにより本体31aに保持される他端部32bを有している。尚、覆土ディスク21は、その中央孔が棒状部材32の一端部32aの支軸32eに遊嵌し、ナット32f等により抜け止めされる。   The rod-shaped member 32 has one end portion 32a corresponding to the free end portion of the soil covering arm 20 to which the soil covering disk 21 is attached, and is inserted into the main body 31a of the rod-shaped member holding mechanism 31 and the inner peripheral surface of the main body 31a by screws 31c. It has the other end part 32b hold | maintained at the main body 31a by pressing. Note that the center hole of the soil covering disk 21 is loosely fitted to the support shaft 32e of the one end portion 32a of the rod-like member 32, and is prevented from coming off by a nut 32f or the like.

また、棒状部材32は、一端部32aと他端部32bとの間に曲げ部32cを有し、それにより棒状部材32の一端部32aが他端部32bに対して傾斜している。つまり、棒状部材32の一端部32aと他端部32bは互いに偏心している。棒状部材32の他端部32bには穴が形成されており、その穴に棒状部材保持機構31の本体31aからの抜けを防止するためのピン32dが嵌合される。   Moreover, the rod-shaped member 32 has the bending part 32c between the one end part 32a and the other end part 32b, and, thereby, the one end part 32a of the rod-shaped member 32 inclines with respect to the other end part 32b. That is, the one end portion 32a and the other end portion 32b of the rod-shaped member 32 are eccentric from each other. A hole is formed in the other end 32b of the rod-shaped member 32, and a pin 32d for preventing the rod-shaped member holding mechanism 31 from coming off from the main body 31a is fitted into the hole.

このように構成されたディスク位置角度調節機構39によれば、ネジ31cを回動してネジ31cによる押し付けを弛めて棒状部材32の他端部32bを棒状部材保持機構31の本体31a内でスライド可能且つ回動可能な状態にし、棒状部材32をスライドさせて覆土ディスク21の位置を矢印A方向と交差する方向における所望の位置に調節し且つ棒状部材32を回動して覆土ディスク21の矢印A方向に対する傾斜角度を所望の角度に調節してから、ネジ31cを今度は逆方向に回動して棒状部材32を本体31aに保持させる。   According to the disk position angle adjusting mechanism 39 configured as described above, the screw 31c is rotated to loosen the pressing by the screw 31c, and the other end 32b of the rod-shaped member 32 is moved within the main body 31a of the rod-shaped member holding mechanism 31. The slidable and turnable state is set, the bar-shaped member 32 is slid to adjust the position of the soil covering disk 21 to a desired position in the direction crossing the arrow A direction, and the bar-shaped member 32 is rotated to rotate the soil covering disk 21. After adjusting the inclination angle with respect to the arrow A direction to a desired angle, the screw 31c is rotated in the opposite direction to hold the rod-shaped member 32 on the main body 31a.

圧縮バネ機構24は、ディスクフレーム17に立設された付勢板18の穴に挿通される一端部を有し且つ覆土アーム20の本体25に形成された枢支板25aに枢支される他端部を有する支持ロッド24aと、付勢板18の穴からの支持ロッド24aの一端部の抜けを防止するためのピン24bと、覆土アーム20への付勢力(即ち、覆土ディスク21の圃場に対する加圧力)の多段階調節を可能とするために支持ロッド24aの長手方向に並設された複数の穴と選択的に嵌合する調節ピン24cと、当該調節ピン24cとディスクフレーム17の付勢板18との間に介在される圧縮バネ24dと、を備えた公知の構成である。   The compression spring mechanism 24 has one end inserted through a hole of an urging plate 18 erected on the disk frame 17 and is pivotally supported by a pivotal support plate 25 a formed on the main body 25 of the soil covering arm 20. A support rod 24a having an end, a pin 24b for preventing one end of the support rod 24a from coming out of the hole of the biasing plate 18, and a biasing force to the soil covering arm 20 (that is, against the field of the soil covering disk 21) Adjustment pin 24c that selectively engages with a plurality of holes arranged in parallel in the longitudinal direction of the support rod 24a, and the urging force of the adjustment pin 24c and the disk frame 17 This is a known configuration including a compression spring 24d interposed between the plate 18 and the plate 18.

この圧縮バネ機構24は、施肥播種機1が圃場を走行する際に、揺動自在な覆土アーム20によって上下動する覆土ディスク21が圃場の凸凹面に略一定圧で押し付けられながら追随するように作用する。   When the fertilizer seeding machine 1 travels in the field, the compression spring mechanism 24 follows the soil covering disk 21 that moves up and down by the swingable soil covering arm 20 while being pressed against the uneven surface of the field with a substantially constant pressure. Works.

上記構成の施肥播種機1を用いて農作業を行なう場合、ホッパー4には粉粒状肥料、そしてホッパー5には種子が充填される。そして施肥播種機1を後部に装着したトラクター等の車両を前進させると、作溝ディスク19により圃場には断面V字状の溝ができ、図示しない駆動機構により繰出装置6,7が駆動され、ホッパー4から繰出装置6、ガイドロート8、そしてガイドパイプ10を経て、圃場に形成された溝から所定距離離れた位置に肥料が投下されるとともに、ホッパー5から繰出装置7、ガイドロート9、そしてガイドパイプ12を経て、種子が該溝に投下され、覆土ディスク21により該肥料および該種子が覆土され、そしてその覆土した土が鎮圧ローラー23により鎮圧される。   When farming is performed using the fertilizer seeder 1 having the above configuration, the hopper 4 is filled with granular fertilizer, and the hopper 5 is filled with seeds. Then, when a vehicle such as a tractor equipped with the fertilizer seeder 1 is advanced, a groove having a V-shaped cross section is formed in the field by the grooving disk 19, and the feeding devices 6 and 7 are driven by a drive mechanism (not shown). The fertilizer is dropped from the hopper 4 through a feeding device 6, a guide funnel 8 and a guide pipe 10 to a position away from a groove formed in the field by a predetermined distance, and from the hopper 5, the feeding device 7, the guide funnel 9 and Through the guide pipe 12, the seed is dropped into the groove, the fertilizer and the seed are covered with the soil covering disk 21, and the soil covered with the soil is pressed down by the pressure reducing roller 23.

その際の覆土装置38の作用について図8を参照しながら説明する。矢印A方向に対し傾斜しながら(つまり、矢印A方向と交差する方向に)延長する覆土ディスク21が、施肥播種機1の矢印A方向への進行に伴い圃場を掻いて土を肥料および種子に被せる。例えば、土質が硬い圃場、耕起されていない圃場、等といった覆土量が減少し易い土質状態の圃場においても十分な覆土量が得られるように施肥播種機1を効果的に作用させるには、圧縮バネ機構24の覆土アーム20への付勢力(即ち、覆土ディスク21の圃場に対する加圧力)を増加させるだけでなく、覆土装置38のディスク位置角度調節機構39の調節も適宜行なう。具体的には、図8に示されるように、棒状部材32を矢印A方向と交差する方向にスライドさせて棒状部材保持機構31から引き出しながら棒状部材32を回転させて覆土ディスク21の矢印A方向に対する傾斜角度を大きくする。尚、この調節による変化は、図8において実線で示される調節前の覆土ディスク21と2点鎖線で示される調節後の覆土ディスク21との違いから理解されるであろう。   The operation of the soil covering device 38 at that time will be described with reference to FIG. The covering soil disk 21 that is inclined with respect to the direction of the arrow A (that is, in a direction crossing the direction of the arrow A) scratches the field as the fertilizer seeding machine 1 advances in the direction of the arrow A to turn the soil into fertilizer and seeds. Cover. For example, in order to effectively operate the fertilizer seeder 1 so as to obtain a sufficient amount of soil covering even in a soil state where the amount of soil covering is easy to decrease, such as a field with a hard soil, an unplowed field, etc. In addition to increasing the urging force of the compression spring mechanism 24 to the soil covering arm 20 (ie, the pressure applied to the field of the soil covering disk 21), the disk position angle adjusting mechanism 39 of the soil covering apparatus 38 is also adjusted as appropriate. Specifically, as shown in FIG. 8, the rod-shaped member 32 is rotated while sliding the rod-shaped member 32 in a direction intersecting with the arrow A direction and pulled out from the rod-shaped member holding mechanism 31, and the arrow A direction of the soil covering disk 21. Increasing the tilt angle with respect to. The change due to this adjustment will be understood from the difference between the uncovered cover disk 21 shown by a solid line in FIG. 8 and the adjusted cover disk 21 shown by a two-dot chain line.

以上、説明したように、本発明の第1実施形態である施肥播種機1(より詳細には、覆土装置38)によれば、覆土装置38の覆土アーム20が、覆土ディスク21の位置を施肥播種機1の進行方向と交差する方向に調節可能にし且つ覆土ディスク21の施肥播種機1の進行方向に対する傾斜角度を調節可能にするディスク位置角度調節機構39を有するので、覆土量が減少し易い土質状態の圃場においても十分な覆土量を得ることができる。   As described above, according to the fertilizer seeding machine 1 (more specifically, the soil covering device 38) according to the first embodiment of the present invention, the soil covering arm 20 of the soil covering device 38 determines the position of the soil covering disk 21 as a fertilizer. Since it has a disk position angle adjustment mechanism 39 that can be adjusted in a direction crossing the traveling direction of the seeding machine 1 and can adjust the inclination angle of the covering soil disk 21 with respect to the traveling direction of the fertilizer seeding machine 1, the amount of soil covering is easy to decrease. A sufficient amount of soil covering can be obtained even in a soil field.

(第2実施形態)
次に、図9および図10を参照して本発明に係る農用作業機の第2実施形態を説明する。尚、以下の説明において、既に説明した施肥播種機1の部材等と同様な構成・作用を有する部材等については、図中に同一符号を付すことにより、説明を簡略化或いは省略する。図9および図10に示されるように、本発明の第2実施形態である施肥播種機100は、上述の施肥播種機1と比較して、覆土装置の覆土アームの構成が異なっており、それ以外の構成要素は施肥播種機1と同じである。
(Second Embodiment)
Next, with reference to FIG. 9 and FIG. 10, 2nd Embodiment of the agricultural working machine which concerns on this invention is described. In addition, in the following description, about the member etc. which have the same structure and effect | action as the member of the fertilizer seeding machine 1 already demonstrated, description is simplified or abbreviate | omitted by attaching | subjecting the same code | symbol in a figure. As shown in FIG. 9 and FIG. 10, the fertilizer seeder 100 according to the second embodiment of the present invention is different from the fertilizer seeder 1 described above in the structure of the soil covering arm of the soil covering device. The other components are the same as the fertilizer seeder 1.

施肥播種機100の覆土装置138の覆土アーム120は、覆土ディスク21の位置を矢印A方向と交差する方向に調節可能にし且つ覆土ディスク21の矢印A方向に対する傾斜角度を調節可能にするディスク位置角度調節機構139を有する。   The soil covering arm 120 of the soil covering device 138 of the fertilizer seeding machine 100 makes it possible to adjust the position of the soil covering disk 21 in a direction crossing the arrow A direction and to adjust the inclination angle of the soil covering disk 21 with respect to the arrow A direction. An adjustment mechanism 139 is provided.

平行リンク16の一方のディスクフレーム17側の枢支軸には、覆土アーム120の本体125の一端部に形成された筒状の枢支部材26が回転自在に遊嵌されている。また、覆土アーム120の本体125の他端部132にはアーム本体保持機構131が取り付けられている。尚、覆土アーム120の本体125は、施肥播種機100の本体17の軸線と平行(換言すれば、図9の矢印A方向と平行)に延長し且つ、第1実施形態の覆土アーム20の本体25と同様にその一端部から他端部132へ向かう途中の所定箇所が湾曲して下方に向かって延長されているが、その延長された部分が更に施肥播種機100の本体17の軸線と交差する方向(換言すれば、図9の矢印A方向と交差する方向に)曲げられて他端部132が形成されている。   A cylindrical pivot member 26 formed at one end of the main body 125 of the soil covering arm 120 is rotatably fitted on the pivot shaft on the one disk frame 17 side of the parallel link 16. An arm main body holding mechanism 131 is attached to the other end 132 of the main body 125 of the soil covering arm 120. The main body 125 of the soil covering arm 120 extends parallel to the axis of the main body 17 of the fertilizer seeding machine 100 (in other words, parallel to the direction of arrow A in FIG. 9), and the main body of the soil covering arm 20 of the first embodiment. 25, a predetermined portion on the way from one end portion to the other end portion 132 is curved and extended downward, but the extended portion further intersects the axis of the main body 17 of the fertilizer seeding machine 100. The other end 132 is formed by being bent (in other words, in a direction crossing the direction of arrow A in FIG. 9).

アーム本体保持機構131は、その筒状の本体131aの周壁に本体131aの内部空間と連通するネジ穴(不図示)を有し、そのネジ穴にネジ131cを螺合させたものであり、覆土アーム120の断面円形の本体125の他端部132を本体131aに挿入可能で且つネジ131cで保持可能である。覆土アーム120の本体125の他端部132を挿入するアーム本体保持機構131の本体131aの内部空間は、覆土アーム120の本体125の他端部132の軸線が覆土ディスク21の軸線に対して交差するように延長している。つまり、アーム本体保持機構131の本体131aの内部空間の軸線(換言すれば、覆土アーム120の本体125の他端部132の軸線)と覆土ディスク21の軸線とは角度を形成している。尚、上述したディスク位置角度調節機構139は、アーム本体保持機構131および覆土アーム120の本体125の他端部132等を総称したものである。   The arm main body holding mechanism 131 has a screw hole (not shown) communicating with the internal space of the main body 131a on the peripheral wall of the cylindrical main body 131a, and screws 131c are screwed into the screw holes. The other end 132 of the main body 125 having a circular cross section of the arm 120 can be inserted into the main body 131a and held by a screw 131c. The internal space of the main body 131 a of the arm main body holding mechanism 131 into which the other end 132 of the main body 125 of the soil covering arm 120 is inserted is such that the axis of the other end 132 of the main body 125 of the soil covering arm 120 intersects the axis of the soil covering disk 21. It is extended to do. That is, the axis of the internal space of the main body 131a of the arm main body holding mechanism 131 (in other words, the axis of the other end 132 of the main body 125 of the soil covering arm 120) and the axis of the soil covering disk 21 form an angle. The disk position angle adjusting mechanism 139 described above is a general term for the arm main body holding mechanism 131, the other end 132 of the main body 125 of the soil covering arm 120, and the like.

アーム本体保持機構131は、覆土ディスク21が取り付けられる覆土アーム120の自由端部に相当する一端部を有している。尚、覆土ディスク21は、その中央孔がアーム本体保持機構131の一端部の支軸に遊嵌し、ナット132f等により抜け止めされる。   The arm main body holding mechanism 131 has one end corresponding to the free end of the soil covering arm 120 to which the soil covering disk 21 is attached. Note that the center hole of the soil covering disk 21 is loosely fitted to a support shaft at one end of the arm main body holding mechanism 131, and is prevented from coming off by a nut 132f or the like.

このように構成されたディスク位置角度調節機構139によれば、ネジ131cを回動してネジ131cによる押し付けを弛めてアーム本体保持機構131の本体131aを覆土アーム120の本体125の他端部132上でスライド可能且つ回動可能な状態にし、アーム本体保持機構131をスライドさせて覆土ディスク21の位置を矢印A方向と交差する方向における所望の位置に調節し且つアーム本体保持機構131を回動して覆土ディスク21の矢印A方向に対する傾斜角度を所望の角度に調節してから、ネジ131cを今度は逆方向に回動して覆土アーム120の本体125の他端部132を本体131aに保持させる。   According to the disk position angle adjusting mechanism 139 configured as described above, the screw 131c is rotated to loosen the pressing by the screw 131c so that the main body 131a of the arm main body holding mechanism 131 is moved to the other end of the main body 125 of the soil covering arm 120. The arm main body holding mechanism 131 is slid to adjust the position of the covering soil disk 21 to a desired position in the direction crossing the arrow A direction, and the arm main body holding mechanism 131 is rotated. After moving and adjusting the inclination angle of the soil covering disk 21 with respect to the arrow A direction to a desired angle, the screw 131c is rotated in the opposite direction, and the other end 132 of the body 125 of the soil covering arm 120 is moved to the body 131a. Hold.

覆土装置138の作用について特に図10(a)および図10(b)を参照しながら説明する。矢印A方向に対し傾斜しながら(つまり、矢印A方向と交差する方向に)延長する覆土ディスク21が、施肥播種機100の矢印A方向への進行に伴い圃場を掻いて土を肥料および種子に被せる。例えば、土質が硬い圃場、耕起されていない圃場、等といった覆土量が減少し易い土質状態の圃場においても十分な覆土量が得られるように施肥播種機100を効果的に作用させるには、圧縮バネ機構24の覆土アーム120への付勢力(即ち、覆土ディスク21の圃場に対する加圧力)を増加させるだけでなく、例えば図10(a)から図10(b)への変化に示されるように覆土装置138のディスク位置角度調節機構139の調節も適宜行なう。尚、図10(b)では実線で示されるように覆土アーム120の本体125の他端部132に対してアーム本体保持機構131を回転させて覆土ディスク21の矢印A方向に対する傾斜角度を図10(a)の実線で示される覆土ディスク21よりも大きくしていることが理解されるであろう。尚、図10(a)の2点鎖線は図10(b)の実線に相当し、そして図10(b)の2点鎖線は図10(a)の実線に相当する。   The operation of the soil covering apparatus 138 will be described with particular reference to FIGS. 10 (a) and 10 (b). The soil covering disk 21 extending while being inclined with respect to the direction of the arrow A (that is, in a direction crossing the direction of the arrow A) scratches the field as the fertilizer seeding machine 100 advances in the direction of the arrow A to turn the soil into fertilizer and seeds. Cover. For example, in order to effectively operate the fertilizer seeder 100 so as to obtain a sufficient soil covering amount even in a soil state where the soil covering amount is likely to be reduced, such as a field where the soil is hard, a field not cultivated, etc. As shown in the change from FIG. 10A to FIG. 10B, for example, the biasing force of the compression spring mechanism 24 to the covering arm 120 (that is, the pressing force of the covering disk 21 to the field) is increased. In addition, the disk position angle adjusting mechanism 139 of the soil covering apparatus 138 is adjusted as appropriate. 10B, as shown by the solid line, the arm body holding mechanism 131 is rotated with respect to the other end portion 132 of the main body 125 of the soil covering arm 120, and the inclination angle of the soil covering disk 21 with respect to the arrow A direction is determined. It will be understood that it is larger than the soil covering disk 21 shown by the solid line in (a). The two-dot chain line in FIG. 10 (a) corresponds to the solid line in FIG. 10 (b), and the two-dot chain line in FIG. 10 (b) corresponds to the solid line in FIG. 10 (a).

以上、説明したように、本発明の第2実施形態である施肥播種機100(より詳細には、覆土装置138)によれば、覆土装置138の覆土アーム120が、覆土ディスク21の位置を施肥播種機100の進行方向と交差する方向に調節可能にし且つ覆土ディスク21の施肥播種機100の進行方向に対する傾斜角度を調節可能にするディスク位置角度調節機構139を有するので、覆土量が減少し易い土質状態の圃場においても十分な覆土量を得ることができる。   As described above, according to the fertilizer seeder 100 (more specifically, the soil covering device 138) according to the second embodiment of the present invention, the soil covering arm 120 of the soil covering device 138 places the position of the soil covering disk 21 on the fertilizer. Since it has the disk position angle adjustment mechanism 139 that can be adjusted in the direction crossing the traveling direction of the seeding machine 100 and that can adjust the inclination angle of the covering soil disk 21 with respect to the traveling direction of the fertilizer seeding machine 100, the amount of soil covering tends to decrease. A sufficient amount of soil covering can be obtained even in a soil field.

施肥播種機100の他の作用や効果については第1実施形態(施肥播種機1)の上記説明から類推可能であるため説明を省略する。   Other actions and effects of the fertilizer seeder 100 can be inferred from the above description of the first embodiment (fertilizer seeder 1), and thus the description thereof is omitted.

When the present invention is applied to a drug application machine, it is a chemical such as an agricultural chemical. For example, when the present invention is applied to a transplanter, it is a seedling. Further, as is apparent from the above-described embodiment, it is needless to say that there may be a plurality of farm work objects of the agricultural working machine according to the present invention.
