Description
【0001】[0001]
この考案は、手作業用の園芸農具に関するものである。 The present invention relates to a horticultural farming tool for manual work.
【0002】[0002]
手作業用の園芸農具は、重量をできる限り軽くする必要から、刃先と軸、また は、刃先と柄が一体となった、いわゆる共柄になっている。 また、替え刃式鍬類は、ほとんどが2本のボルトによって組み立てられている 。 実願平3−95975は、軸に長円形の突起1個と、ボルトが入る孔1個を有 し、長円形の孔1個と、角孔1個とを有する替え刃を、角根丸頭ボルト1本で組 み立てた構造になっている。 Since gardening tools for manual work need to be as light as possible, they have a so-called co-pattern in which the cutting edge and shaft, or the cutting edge and handle are integrated. Most replaceable blade hoes are assembled with two bolts. In Japanese Patent Application No. 3-95975, a replaceable blade having one oval projection on the shaft, one hole into which a bolt is inserted, one oval hole, and one square hole is used. The structure is assembled with one head bolt.

実願平3−95975は、軸と替え刃の、双方の突起と孔との距離の製作誤差 を補うために、長円形の突起と孔としたものであるが、重量をできる限り軽くす るためには問題がある。 また、ナットのゆるみ止めのための措置がとられていない。 In Japanese Patent Application No. 3-95975, an oval protrusion and a hole are used to compensate for a manufacturing error in the distance between the protrusion and the hole on the shaft and the blade, but the weight is reduced as much as possible. There is a problem for you. Also, no measures are taken to prevent the nuts from loosening.

軸の突起を円形にし、替え刃には、軸の突起に嵌合する円形の孔を設ける。。 替え刃の角孔の大きさは、軸と直角方向は、角根丸頭ボルトの角根部の幅と同 じであるが、軸方向の長さを、角根丸頭ボルトの角根部の幅よりも少し大きくす る。 ナットは、スリーブナットを使用し、軸に設けた角根丸頭ボルトが入る孔には スリーブナットのテーパ部と合うテーパ部を有している。 The shaft protrusion is circular, and the blade is provided with a circular hole that fits into the shaft protrusion. . The size of the square hole of the blade is the same as the width of the square root of the square root bolt, but the axial length is the width of the square root bolt of the square root bolt. A little bigger than. For the nut, a sleeve nut is used, and the hole into which the round root bolt is mounted on the shaft has a taper part that matches the taper part of the sleeve nut.

【作用】 軸の円形の突起と、替え刃の円形の孔を嵌め合わせ、角根丸頭ボルトの角根部 と替え刃の角孔を嵌め合わせると共に角根丸頭ボルトを軸の孔に通し、スリーブ ナットにより軸と替え刃を組み立てる。[Operation] Fit the circular protrusion of the shaft and the circular hole of the spare blade, fit the square root of the square root bolt and the square hole of the spare blade, and pass the square root bolt through the shaft hole. Assemble the shaft and spare blade with the sleeve nut.

【実施例2】 本考案による移植ごては、への字型に曲げられた軸(1’)の先端には、角根 丸頭ボルト(3’)が入る孔(5’)が設けられ、スリーブナット(4’)のテ ーパ部と合うテーパ部を有している。 軸(1’)の下面には円形の突起(6’)が設けられ、突起部分を除いた外は 替え刃(2’)が取り付けられるように平坦になっている。 軸(1’)の下面に設けた円形の突起(6’)に、替え刃(2’)の円形の孔 (9’)を嵌め合わせ、角根丸頭ボルト(3’)の角根部(7’)と、替え刃( 2’)の角孔(8’)を嵌め合わせると共に、角根丸頭ボルト(3’)を軸(1 ’)の孔(5’)に通し、スリーブナット(4’)によって、軸(1’)と替え 刃(2’)とを組み立て固定した替え刃式移植ごてである。[Embodiment 2] The implanting iron according to the present invention is provided with a hole (5 ') into which a square root round head bolt (3') is inserted at the tip of a shaft (1 ') bent in a V shape. , And has a taper that matches the taper of the sleeve nut (4 '). A circular protrusion (6 ') is provided on the lower surface of the shaft (1'), and the outside of the protrusion (6 ') is flat so that a replacement blade (2') can be attached. Fit the circular hole (9 ') of the spare blade (2') into the circular protrusion (6 ') provided on the lower surface of the shaft (1'), and then attach the square root of the square root bolt (3 ') ( 7 ') and the square hole (8') of the spare blade (2 ') are fitted together, the square root round head bolt (3') is passed through the hole (5 ') of the shaft (1'), and the sleeve nut ( 4 ') is a replacement blade type implanting iron in which a shaft (1') and a replacement blade (2 ') are assembled and fixed.

【考案の効果】 組立用のボルトは1本しか使用せず、重量の増加を抑えている。また、スリー ブナットを使用することにより、ナットがゆるむのを防いでいる。 軸の下面の突起は、実願平3−95975は長円形であるが、本考案の突起は 円形のため軸の長さを短くし、また、替え刃の刃幅を短くすることが出来る。 そのために、より重量を軽くすることが出来る。 替え刃の角孔は軸方向に少し長いため、軸の突起と孔の距離に製作誤差があっ ても組み立てることが出来る。 また、この角孔は軸と直角方向の長さは、角根丸頭ボルトの角根部の幅に等し いため、ボルトの角根部と替え刃の角孔を嵌め合わせると共に、軸の円形の突起 と替え刃の円形の孔を嵌め合わせ組み立てるため、替え刃はボルトまたは円形の 突起を中心に回転することはない。[Effects of the Invention] Only one bolt for assembly is used to prevent an increase in weight. In addition, the use of three nuts prevents the nuts from loosening. The protrusion on the lower surface of the shaft is oval in Japanese Patent Application No. 3-95975, but since the protrusion of the present invention is circular, the length of the shaft can be shortened and the blade width of the spare blade can be shortened. Therefore, the weight can be reduced. Since the square hole of the blade is a little long in the axial direction, it can be assembled even if there is a manufacturing error in the distance between the shaft protrusion and the hole. Also, the length of this square hole in the direction perpendicular to the shaft is not equal to the width of the square root part of the square root round head bolt, so the square root part of the bolt and the square hole of the replacement blade are fitted together, and the circular projection of the shaft Since the circular hole of the blade is fitted and assembled, the blade does not rotate around the bolt or the circular protrusion.
