Description

本発明は、複数のディスク対で中耕除草、培土の管理作業を行う中耕除草機に関するものである。   The present invention relates to a middle tillage weeding machine that performs management work of middle tillage weed and cultivating soil with a plurality of disk pairs.

従来、一対のディスクを前後に2列配置し、トラクタ又は乗用管理機の牽引前進によってこれらのディスクで条間の土を横方向へ反転移動させて中耕除草作業または培土(土寄せ)作業を行うディスク式中耕除草機が知られている(例えば、特許文献1参照)。   Conventionally, a pair of disks are arranged in two rows on the front and rear, and the cultivating and weeding work is done by reversing and moving the soil between the ridges laterally with these disks by pulling forward of the tractor or riding management machine. A plowing weeder is known (for example, see Patent Document 1).

このディスク式中耕除草機は、機体に前端部が上下動可能に接続されて進行方向後側へ延びて機体幅方向に並設された第1アーム及び第2アームと、これらのアームの前側及び後側に横方向軸周りに回転自在に支持されて条間の土を中耕培土する前列ディスク及び後列ディスクを備えている。第1アーム及び第2アームは、機体幅方向に角度調節が可能に設けられている。また、前列ディスク及び後列ディスクは、対応する第1アーム及び第2アームに設けられた回動支点を中心にして回動可能で且つ角度調節可能に支持されている。また一対の前列ディスクの前方にはチゼルが設けられ、このチゼルは一対の前列ディスクの機体幅方向ほぼ中央部の前方に設けられている。   This disc type middle tiller has a first arm and a second arm, the front end of which is connected to the fuselage so as to be movable up and down, extends rearward in the traveling direction, and is juxtaposed in the width direction of the fuselage, and the front side of these arms and A rear row disc and a rear row disc are supported on the rear side so as to be rotatable around a horizontal axis and are used for medium cultivation of the soil between the strips. The first arm and the second arm are provided so that the angle can be adjusted in the body width direction. Further, the front row disc and the rear row disc are supported so as to be rotatable about a rotation fulcrum provided on the corresponding first arm and second arm and to be adjustable in angle. Further, a chisel is provided in front of the pair of front row disks, and this chisel is provided in front of the center portion of the pair of front row disks in the body width direction.

このような従来のディスク式中耕除草機は、前列ディスク及び後列ディスクを作物の条間に設置した状態で条間を進行すると、チゼルが条間の土中に貫入して条間の土を膨軟にし、膨軟にされた土は、前列ディスク及び後列ディスクによって中耕培土される。   In such a conventional disc type mid-plow weeder, when the front row disc and the rear row disc are installed between the rows of crops, the chisel penetrates into the soil between the rows and expands the soil between the rows. The softened and softened soil is medium-cultivated by the front row disc and the rear row disc.

特開2007−259812号公報(段落0038、図2)JP 2007-259812 (paragraph 0038, FIG. 2)

この従来のディスク式中耕除草機の後列ディスクは、チゼルによって膨軟にされた土の外側の硬い所を通るため、圃場の条間の土が硬い場合には、後列ディスクが条間の土に入り込み難くなり、作物への培土量が不足する場合がある。   The rear row disc of this conventional disc type middle weeder passes through a hard place outside the soil that has been loosened by the chisel, so that if the soil between the rows in the field is hard, the rear row disc becomes the soil between the rows. It may become difficult to enter, and the amount of soil in the crop may be insufficient.

本発明は、このような課題を解決するためになされたものであり、後列ディスクが条間の土に入り込み易く、作物への培土量の増大が可能な中耕除草機を提供することを目的とする。   The present invention has been made to solve such problems, and an object of the present invention is to provide a middle tillage weeder capable of increasing the amount of cultivated soil to the crop because the rear row disk can easily enter the soil between the rows. To do.

このような課題を解決するため、本発明は、条間幅方向に延びて支持されたメインフレームに前端側が接続されて進行方向後側へ延びる支持フレームの前側と後側の各両側に、回転自在に支持され、進行方向前側に対して後側が後方斜め外側に傾斜した一対の前列ディスク及び一対の後列ディスクを備え、前列ディスク及び後列ディスクが作物の条間を進行しながら条間の土を中耕培土する中耕除草機において、一対の前列ディスクは、進行方向前後位置を揃えて配置され、一対の前列ディスクの一方側に配設された前列ディスクと一対の後列ディスクの一方側に配設された後列ディスクとの間で前列ディスクの条間幅方向外側かつ後列ディスクの条間幅方向略中央、及び一対の前列ディスクの他方側に配設された前列ディスクと一対の後列ディスクの他方側に配設された後列ディスクとの間で前列ディスクの条間幅方向外側かつ後列ディスクの条間幅方向略中央に、一対のチゼルが設けられ、一対のチゼルと一対の後列ディスクとの間に、一対の前列ディスクによって中耕されない残耕を条間幅方向外側へ排除する排土機構部が設けられていることを構成要件とする。 In order to solve such a problem, the present invention is configured so that the front end side is connected to the main frame that is supported by extending in the inter-span width direction and is rotated on both the front side and the rear side of the support frame that extends rearward in the traveling direction. A pair of front row discs and a pair of rear row discs that are freely supported and whose rear side is inclined rearward and obliquely outward with respect to the front side in the traveling direction, and the front row discs and the rear row discs move the soil between the rows while moving between the rows of crops. In a middle tillage weeder that performs medium tillage cultivation, the pair of front row disks are arranged with their front and rear positions aligned in the advancing direction, and are arranged on one side of the front row disk and the pair of rear row disks arranged on one side of the pair of front row disks. and front row disc strip between the widthwise outer and rear strip between the substantial center in a transverse direction of the disk, and a pair of front row disc other side disposed the front row disc and a pair of rear row in between the rear row disc The strip between the substantial center in a transverse direction of strip between the widthwise outer and back row disc front row disc between the rear row disc arranged on the other side of the disk, a pair of chisels is provided, a pair of chisel and a pair of rear row disc between, and configuration requirements that soil discharge mechanism is provided to eliminate Zanko not intertillage by a pair of front row disc to strip between widthwise outer.

一対の前列ディスクを進行方向に対して前後にずらさずに取り付け、これらのディスクの角度調整を可能にすると、ディスク間に残耕ができる場合がある。この残耕の発生を防止するため、一対のチゼルと一対の後列ディスクとの間で一対の前列ディスクの条間幅方向間に、一対の前列ディスクによって中耕されない残耕を条間幅方向外側へ排除する排土機構部が設けられている(請求項)。 If a pair of front row disks are attached without being shifted back and forth with respect to the traveling direction, and the angle of these disks can be adjusted, there is a case where residual tilling can be performed between the disks. In order to prevent the occurrence of this residual tillage, between the pair of chisels and the pair of rear row disks, between the width direction of the pair of front row disks, the residual tillage that is not intermediately plowed by the pair of front row disks is moved outward in the width direction of the interline. A soil removal mechanism portion to be excluded is provided (claim 1 ).

チゼルの配設位置の条件の1つである条間幅方向内側とは、後列ディスクの傾き角度や取り付け位置が調節可能である場合には、位置調節された後の後列ディスクの条間幅方向内側をいう。このため、後列ディスクの傾き角度や取り付け位置が調節されて、後列ディスクの条間幅方向内側の領域の位置がずれた場合を考慮して、一対のチゼルは条間幅方向に位置調節可能に設けられている(請求項2)。   One of the conditions of the chisel placement position is the inner side in the inter-strip width direction. When the tilt angle and the mounting position of the rear row disk can be adjusted, the inter-strip width direction of the rear row disk after position adjustment Say inside. Therefore, considering the case where the tilt angle and mounting position of the rear row disc are adjusted and the position of the area inside the inter-row width direction of the rear row disc is shifted, the position of the pair of chisels can be adjusted in the inter-width direction. (Claim 2).

チゼルの位置調節は、チゼルを条間幅方向の任意の位置に移動させて固定し、また条間幅方向に所定距離毎に移動させて固定してもよい。   The position adjustment of the chisel may be fixed by moving the chisel to an arbitrary position in the width direction of the striations, or by moving it in the width direction of the striations by a predetermined distance.

対の前列ディスクが条間幅方向に間隔を有して配設されている場合には、一対の前列ディスク間の土は一対の前列ディスクによって中耕されない。このため、一対のチゼルと一対の後列ディスクとの間で且つ該一対の前列ディスクの条間幅方向間に排土機構部を設けると、一対の前列ディスクでは中耕されない残耕を条間幅方向外側へ排除することができる。排土機構部は前部に排土側チゼル部が配設され、該排土側チゼル部の幅方向両側には後方斜め外側に傾斜する一対の排土板が設けられていることで(請求項)、排土側チゼル部によって残耕を膨軟にし、膨軟にされた残耕は排土板によって条間幅方向外側へ排除され、この排除された残耕は排土機構部よりも進行方向後側に配設された一対の後列ディスクによって培土される。 When a pair of front row disc is arranged at a distance to the strip between the transverse direction, soil between the pair of front row disc is not Intertillage by a pair of front row disc. For this reason, when a soil removal mechanism is provided between the pair of chisels and the pair of rear row disks and between the pair of front row disks, the remaining tillage that is not intermediately plowed by the pair of front row disks Can be excluded to the outside. The soil removal mechanism portion is provided with a soil discharge side chisel portion at the front, and a pair of soil discharge plates that are inclined obliquely outward and rearward are provided on both sides in the width direction of the soil discharge side chisel portion. Item 3 ), after plowing is softened by the soil removal side chisel, and the softening after plowing is removed to the outside in the width direction by the soil removal plate. Is also cultivated by a pair of rear row disks arranged on the rear side in the traveling direction.

排土機構部は、後方斜め外側に傾斜する一対の排土板を平面視においてハ字状に配置したものにすると、一対の前列ディスクでは中耕されない残耕を条間幅方向両側に排出して、条間両側の作物に培土することができる。   When the earth removal mechanism part is configured by arranging a pair of earth removal boards inclined obliquely outward and rearward in a plan view, the pair of front row discs discharges residual tillage that is not intermediately plowed to both sides in the inter-width direction. Can be cultivated on both sides of the crop.

チゼルは、支持フレームに連結された連結支持フレームに前後方向に回動自在に支持されるとともにシャーボルトを介して連結支持フレームに固定されていることを構成要件とする(請求項)。チゼルの前進時にチゼルに石等の障害物が当接すると、シャーボルトが破断し、チゼルはフリーな状態となって連結支持フレームとの回動支点を中心として後方側に回動する。このため、各フレームやチゼルが損傷する事態を未然に防止することができる。 The chisel is supported by a connection support frame connected to the support frame so as to be pivotable in the front-rear direction, and is fixed to the connection support frame via a shear bolt (claim 4 ). When an obstacle such as a stone comes into contact with the chisel during the advancement of the chisel, the shear bolt breaks, and the chisel becomes free and pivots rearward about the pivot support point with the connection support frame. For this reason, the situation where each flame | frame or chisel is damaged can be prevented beforehand.

本発明に係わる中耕除草機によれば、一対の前列ディスクを、進行方向前後位置を揃えて配置し、一対の前列ディスクの一方側に配設された前列ディスクと一対の後列ディスクの一方側に配設された後列ディスクとの間で前列ディスクの条間幅方向外側かつ後列ディスクの条間幅方向略中央、及び一対の前列ディスクの他方側に配設された前列ディスクと一対の後列ディスクの他方側に配設された後列ディスクとの間で前列ディスクの条間幅方向外側かつ後列ディスクの条間幅方向略中央に、一対のチゼルを設け、一対のチゼルと一対の後列ディスクとの間に、一対の前列ディスクによって中耕されない残耕を条間幅方向外側へ排除する排土機構部を設けることで、チゼルによって膨軟にされた土に後列ディスクが深く入り込むことができる。このため、作物への培土量の増加が可能な中耕除草機を提供することができる。 According to the middle tiller according to the present invention, the pair of front row disks are arranged with their front and rear positions aligned in the advancing direction, and the front row disk disposed on one side of the pair of front row disks and the one side of the pair of rear row disks. Between the front row disc and the pair of rear row discs arranged on the outer side in the inter-strip width direction of the front row disc and the substantially center of the rear row disc in the inter-strip width direction, and the other side of the pair of front row discs. the strip between the substantial center in a transverse direction of strip between the widthwise outer and back row disc front row disc between the rear row disc arranged on the other side, a pair of chisel, between the pair of chisel and a pair of rear row disc to, by providing the dumping mechanism to eliminate Zanko not intertillage by a pair of front row disc to strip between widthwise outer can back row disc enters deeply into the soil that is to膨軟by chisel For this reason, the middle tillage weeding machine which can increase the amount of cultivation to a crop can be provided.

The support part 51 is a rod-shaped member having a hexagonal cross-sectional shape, and a holder 54 is inserted on the upper part of the support part 51 so as to be movable in the axial direction of the support part. The holder 54 includes a cylindrical portion 54a to be inserted into the support body portion 51, and a holder main body portion 54b fixed to the front side of the cylindrical portion 54a. The cylindrical portion 54 a is provided with a hole (inside the hexagonal shape) similar to the cross-sectional shape of the support portion 51. For this reason, when the support body part 51 is inserted in the cylinder part 54a, the support body part 51 is movable up and down with respect to the cylinder part 54a, while the rotation in the cylinder part circumferential direction is restricted. . The cylindrical portion 54a is provided with a fixing bolt 55 that is screwed in the radial direction to restrict the vertical movement of the support body portion 51. For this reason, when the support body 51 is inserted into the tube portion 54a with the chisel portion 52 facing forward in the traveling direction and the support body portion 51 is fixed to the tube portion 54a by the fixing bolt 55, the chisel portion 52 is always in the traveling direction. It can fix to the cylinder part 54a in the state which faced the front. In addition, the cross-sectional shape of the support body part 51 and the shape of the hole part which penetrates the support body part 51 are not restricted to hexagonal shape, Rectangular shape, such as triangular shape and square shape, may be sufficient.

このチゼル50は、ホルダー54のホルダ本体部54b内に挿通された中間支持体57を介して連結支持フレーム14に固定支持されている。中間支持体57は内側に連結支持フレーム14が挿通可能な四角形状の孔部を有した中間筒部57aと、中間筒部57aの一端側に固着されて上方へ張り出す結合板部57bとを有してなる。中間筒部57aの外側の断面形状はホルダ本体部54b内の孔部の断面形状よりも小さな相似形を有して、ホルダ本体部54b内の孔部内に中間筒部57aが挿通されている。結合板部57bの下側には中間筒部57aの孔部と略同一形状の連通孔部が形成されて、連結支持フレーム14が挿通されている。   The chisel 50 is fixedly supported by the connection support frame 14 via an intermediate support 57 inserted into the holder main body 54 b of the holder 54. The intermediate support 57 includes an intermediate cylinder part 57a having a rectangular hole portion through which the connection support frame 14 can be inserted, and a coupling plate part 57b fixed to one end of the intermediate cylinder part 57a and projecting upward. Have. The cross-sectional shape of the outer side of the intermediate cylinder part 57a has a similar shape smaller than the cross-sectional shape of the hole part in the holder main body part 54b, and the intermediate cylinder part 57a is inserted into the hole part in the holder main body part 54b. A communication hole portion having substantially the same shape as the hole portion of the intermediate cylinder portion 57a is formed below the coupling plate portion 57b, and the connection support frame 14 is inserted therethrough.

結合板部57bの上部にはボルト15の軸部15aが挿通可能な孔部が設けられている。この孔部は、連結支持フレーム14に中間支持体57を挿通すると、フランジ部14aに設けられた孔部と連通可能な位置に設けられている。このため、連通状態にある孔部にボルト15の軸部15aを挿通してナット17を螺合することで、フランジ部14aに中間支持体57を固定することができる。連通状態にある孔部に挿通されるボルト15については後述する。   A hole through which the shaft portion 15a of the bolt 15 can be inserted is provided in the upper portion of the coupling plate portion 57b. The hole is provided at a position where the hole can be communicated with the hole provided in the flange portion 14a when the intermediate support 57 is inserted into the connection support frame 14. For this reason, the intermediate | middle support body 57 can be fixed to the flange part 14a by inserting the axial part 15a of the volt | bolt 15 in the hole part in a communication state, and screwing the nut 17 into it. The bolt 15 inserted through the hole in the communication state will be described later.

ホルダ本体部54bの上側及び下側を形成する各側板には、ボルト16が螺合可能なねじ孔(図示せず)が設けられている。このねじ孔にボルト16の軸部を螺合して軸部の先端部を中間支持体57の中間筒部57aの表面に当接させると、ホルダー54を中間支持体57に固定することができる。このため、中間支持体57の長手方向にホルダー54を移動させて中間支持体57に固定することで、ホルダー54を介してチゼル50を条間幅方向に位置調節することができる。   Each side plate forming the upper side and the lower side of the holder main body portion 54b is provided with a screw hole (not shown) into which the bolt 16 can be screwed. The holder 54 can be fixed to the intermediate support 57 by screwing the shaft of the bolt 16 into the screw hole and bringing the tip of the shaft into contact with the surface of the intermediate cylinder 57a of the intermediate support 57. . For this reason, by moving the holder 54 in the longitudinal direction of the intermediate support 57 and fixing the holder 54 to the intermediate support 57, the position of the chisel 50 can be adjusted in the width direction of the stripes via the holder 54.

結合板部57bの孔部に挿通されてフランジ部14aに締結されるボルト15は、いわゆるシャーボルトである。このため、図5(a)に示すように、チゼル50が矢印A方向に進行しているときに、チゼル50が圃場に存在する石等の障害物に当接して矢印B方向の負荷がチゼル部52に作用すると、チゼル50は、連結支持フレーム14の中心軸線を回動支点Oとして反時計方向に回動しようとしてシャーボルトであるボルト15に剪断力が作用する。この剪断力がシャーボルトを破断させるに必要な力よりも大きい場合には、シャーボルトは破断する。   The bolt 15 inserted through the hole portion of the coupling plate portion 57b and fastened to the flange portion 14a is a so-called shear bolt. For this reason, as shown in FIG. 5A, when the chisel 50 is traveling in the direction of arrow A, the chisel 50 abuts against an obstacle such as a stone existing in the field and the load in the direction of arrow B is When acting on the portion 52, the chisel 50 acts on the bolt 15, which is a shear bolt, to rotate counterclockwise with the central axis of the connection support frame 14 as the rotation fulcrum O. When this shearing force is larger than the force necessary to break the shear bolt, the shear bolt breaks.

その結果、チゼル50は、図5(b)に示すように、連結支持フレーム14の中心軸線を回動支点Oとして反時計方向に回動し、チゼル50に大きな負荷が作用する事態が防止されて、チゼル50やこれを支持する連結支持フレーム14等の損傷を未然に防止することができる。   As a result, as shown in FIG. 5B, the chisel 50 rotates counterclockwise with the central axis of the connection support frame 14 as the rotation fulcrum O, and a situation where a large load acts on the chisel 50 is prevented. Thus, damage to the chisel 50 and the connection support frame 14 that supports the chisel 50 can be prevented in advance.

図2及び図3に示すように、一対の後列ディスク40と一対のチゼル50との間で且つ一対の前列ディスク30の条間幅方向の中間部には、一対の前列ディスク30の条間幅方向間の中耕されない残耕を条間幅方向外側へ排除する排土機構部60が設けられている。   As shown in FIGS. 2 and 3, between the pair of rear row disks 40 and the pair of chiseles 50 and in the middle of the pair of front row disks 30 in the width direction between the pair of front row disks 30, There is provided a soil removal mechanism 60 that excludes residual tillage that is not cultivated between directions to the outside in the inter-width direction.

排土機構部60は、前部に配設された排土側チゼル部61と、排土側チゼル部61の幅方向両側に配設されて後方斜め外側に傾斜する一対の排土板62と、これら排土側チゼル部61及び排土板62を支持する支持部材63とを有してなる。支持部材63は上下方向に延び、その上端部が連結支持フレーム14に固定されている。支持部材63の下部の前側に排土側チゼル部61が設けられ、この排土側チゼル部61の条間幅方向両側に排土板62が取り付けられている。なお、排土機構部60は、連結支持フレーム14に固定された状態で設けられているが、前述したチゼル50のようにシャーボルトを介して連結支持フレーム14に取り付けて、シャーボルトの破断時には、排土機構部60が進行方向後方側へ回動するようにしてもよい。   The soil removal mechanism 60 includes a soil discharge side chisel portion 61 disposed in the front portion, and a pair of soil discharge plates 62 disposed on both sides in the width direction of the soil discharge side chisel portion 61 and inclined rearward and obliquely outward. And a support member 63 that supports the soil discharge side chisel portion 61 and the soil discharge plate 62. The support member 63 extends in the vertical direction, and an upper end portion thereof is fixed to the connection support frame 14. A soil discharge side chisel portion 61 is provided on the front side of the lower portion of the support member 63, and soil discharge plates 62 are attached to both sides of the soil discharge side chisel portion 61 in the inter-width direction. The earth removal mechanism 60 is provided in a state of being fixed to the connection support frame 14, but is attached to the connection support frame 14 via a shear bolt like the above-described chisel 50, and when the shear bolt is broken. The earth removal mechanism 60 may be rotated backward in the traveling direction.

このように構成された中耕除草機1によって、作物の条間の圃場を中耕培土する場合には、図2に示すように、中耕ユニット20、20'、20'が作物の条間に配置されるように中耕除草機1を設置する。走行機体90が前進走行して中耕除草機1が前進すると、図1(a)に示すように、一対の前列ディスク30によって中耕された土は、前列ディスク30の前面に沿って進行方向後側に流れて作物Pに培土される。   In the case where the medium field between the crop lines is cultivated by the medium tillage weeder 1 configured as described above, the middle tillage units 20, 20 ′ and 20 ′ are arranged between the crop lines as shown in FIG. In this way, the middle tillage weeder 1 is installed. When the traveling machine body 90 travels forward and the middle plowing weeder 1 moves forward, the soil cultivated by the pair of front row disks 30 is moved rearward along the front surface of the front row disks 30 as shown in FIG. And then cultivated in crop P.

前列ディスク30の条間幅方向外側の中耕されずに残った残耕のうちのチゼル側の残耕Z1は、チゼル50によって膨軟にされる。またこの膨軟にされた土よりも条間幅方向内側の土もチゼル50によって膨軟にされる。このため、後列ディスク40の進行方向前方の土はその殆どが膨軟にされた状態になり、後列ディスク40は条間の土に入り込み易くなる。従って、後列ディスク40は所望の深さを有して条間の土に入り込んで作物Pに培土することができ、作物Pへの培土量が不足する虞を無くすことができる。   The chisel side residual tillage Z1 of the remaining tillage remaining without being cultivated outside the front row disk 30 in the inter-width direction is expanded by the chisel 50. Further, the soil on the inner side in the inter-strip width direction of the softened soil is also softened by the chisel 50. For this reason, most of the soil in the forward direction of the rear row disk 40 is in a bulging state, and the rear row disk 40 is easy to enter the soil between the stripes. Therefore, the rear row disc 40 has a desired depth and can enter the soil between the strips and be cultivated on the crop P, thereby eliminating the possibility that the amount of cultivated soil on the crop P is insufficient.

また図1(b)に示すように、一対の前列ディスク30の条間幅方向の中間の土は前列ディスク30によって中耕されることなく残耕Z2として残る。しかし、この残耕Z2は、排土機構部60の排土側チゼル部61(図3参照)によって膨軟にされ、この膨軟にされた残耕Z2の条間幅方向一方側及び他方側の土は、排土機構部60の一対の排土板62によって一対の後列ディスク40の進行方向前方に供給される。このため、一対の後列ディスク40によって作物Pに培土される土の量を増大することができる。   Further, as shown in FIG. 1B, the middle soil in the width direction between the pair of front row disks 30 remains as residual tillage Z <b> 2 without being cultivated by the front row disks 30. However, the residual tillage Z2 is softened by the soil removal side chisel part 61 (see FIG. 3) of the soil removal mechanism 60, and one side and the other side in the inter-width direction of the residual tillage Z2 thus softened. The soil is supplied to the front of the pair of rear row disks 40 in the traveling direction by the pair of earth removing plates 62 of the earth removing mechanism 60. For this reason, the amount of soil cultivated in the crop P by the pair of rear row disks 40 can be increased.
