竹の子は地下約２５〜３０ｃｍの竹の根から芽を出し竹の子となる。竹の子を機械で採取するのは困難で、専ら鍬を用いて竹の子を掘り出している。日本の竹の子の生産はほとんどが中高年以上の高齢者の手によって行われているところ、竹の子を掘り出すには大変な労力を必要とするため、いかに労力を伴わずに容易に竹の子を掘り出せるかが長年の課題とされてきた。   Bamboo shoots shoot from bamboo roots of about 25-30 cm underground and become bamboo shoots. It is difficult to collect bamboo shoots with a machine, and the bamboo shoots are dug out exclusively using firewood. Japan's bamboo shoots are mostly produced by middle-aged and older elderly people, so it takes a lot of labor to dig bamboo shoots, so how can you easily dig bamboo shoots without any effort? It has been a longstanding challenge.

竹の子の掘り出し方法について述べると、竹の子は地下約２５〜３０ｃｍのところにある竹の根から出ているので、鍬（山鍬）の刃を竹の子が芽を出している根元付近から地中へ向け大よそ２０〜４０度の角度で力強く打ち込み、テコの原理を利用して鍬の柄の先端を腕力で引いたり押したりして竹の子を掘り出す。強靭な竹の根、竹の子自身、周囲の土と他の植物の根の抵抗等があるため、この作業は力のある者でも一度鍬を打ち込むと容易に動かせず、まして、生産者の大部分である中高年以上の者にとって、その労力負担は計り知れないものである。更に、竹の子を掘り出す際に鍬の根元に大きな応力が作用するので、繰り返し使用により、柄が根元から折れ易いという耐久性の問題もあった。   As for the method of digging out bamboo shoots, bamboo shoots come out from the roots of bamboo about 25-30 cm below the ground, so the blades of the bamboo shoots are directed toward the ground from the roots where the bamboo shoots sprout. It is struck powerfully at an angle of about 20-40 degrees, and the bamboo shoots are dug by pulling and pushing the tip of the heel handle with arm force using the principle of leverage. Because there are strong bamboo roots, bamboo shoots themselves, the resistance of the surrounding soil and the roots of other plants, this work can not be easily moved even if it is powerful, once it is driven, and most of the producers For middle-aged and older people, the burden of labor is immeasurable. Furthermore, when a bamboo shoot is dug, a large stress acts on the base of the cocoon, so that there is a problem of durability that the handle is easily broken from the base by repeated use.

一方、竹の子用の鍬に関する改良が提案されている（特許文献１参照）。   On the other hand, the improvement regarding the bamboo basket is proposed (refer patent document 1).

Then, put the left foot) on the tread plate 24 of the footrest 12 and apply the weight. Based on the lever principle, the bamboo shoot T can be easily lifted regardless of the resistance of the strong bamboo root, the bamboo shoot itself, the surrounding soil and the roots of other plants. At this time, when the blade 3 of the kite 1 is driven into the ground G, the height of the tread plate 24 is about 14 to 20 cm from the ground to the tread plate 24 when the driving angle is 45 degrees. The foot can be easily put on the tread plate 24 and the weight can be applied without the stepping position being too high. Moreover, the weight of the assisting tool 10 for heels is very light with about 900g. Since the stress applied to the shape change portion of the handle 2 can be reduced, the handle 2 is hardly broken and the durability can be improved.
