Abstract
Description
この発明は、交換可能な管型形成刃先に関する。 The present invention relates to a replaceable tube forming blade edge.
従来、管型形成刃先を使用したものは、サイレージ、乾草などの家畜用飼料の品質評価のための試料を取るために、採取円筒をドリル駆動により円筒内に標本試料を採取可能にしたドリル式コアサンプラーがある。 Conventionally, the one that uses a tube-shaped cutting edge is a drill type in which a sampling cylinder can be sampled in the cylinder by driving the sampling cylinder to take a sample for quality evaluation of livestock feed such as silage and hay. There is a core sampler.
草食動物である牛は、牧草イネなどの繊維含量の多い飼料、いわゆる粗飼料を一定量以上給与しなければならない。 Cattle that are herbivores must feed a certain amount of feed with high fiber content such as pasture rice, so-called roughage.
しかし、粗飼料の成分、消化率は牧草の種類、刈り取り時期、貯蔵法などによって大きく変動することから、牛に与えるまえにサンプリングして分析する必要がある。このような背景から、正確なサンプリングを行うために、ドリル式コアサンプラーが開発されている。 However, forage components and digestibility vary greatly depending on the type of grass, harvesting time, storage method, etc., so it is necessary to sample and analyze them before feeding them to cattle. Against this background, drill-type core samplers have been developed in order to perform accurate sampling.
このドリル式コアサンプラーは、金属製円筒で先端部に刃があり、底面にドリルに装着するための軸を付帯したものであり、先端の刃は帯鋸刃を回転方向と逆向きに溶接したものや筒の先端に多数もしくは少数の刃を金属円筒と一体として直接波形の刃を反復形成したものがある。 This drill-type core sampler is a metal cylinder with a blade at the tip, with a shaft attached to the bottom of the drill, and the blade at the tip is a band saw blade welded in the direction opposite to the rotation direction In some cases, a corrugated blade is directly formed by integrating a large or small number of blades with a metal cylinder at the tip of a tube.
コアサンプラーの刃は、使用していくうちに磨耗して変形し、いくら磨いても切れ難くなる。また、使用中に不注意で落下させて刃を変形させることも多い。 The core sampler blade wears and deforms over time, and becomes hard to cut no matter how much it is polished. Also, the blade is often deformed by inadvertent dropping during use.
このような場合、刃を溶接したコアサンプラーでは、変換が困難であるし、また、金属製円筒と一体として刃を直接波形に反復形成したものでは、修理ができず、新品を購入する必要に迫られる。従って、低コストで刃を交換できるものが求められている。 In such a case, it is difficult to convert with a core sampler with welded blades, and it is not possible to repair a product that has a blade formed directly into a corrugated shape integrally with a metal cylinder, and it is necessary to purchase a new one. Be forced. Therefore, what can replace | exchange a blade at low cost is calculated | required.
さらに、本発明は、飼料のサンプリング用のコアサンプラーだけでなく、下記に述べる，管型形成刃としての用途にも適応可能性がある。
１）壁等に穴をあけるためのコアドリルやホールソー
２）コンクリートなどの穿孔用に用いる刃先交換型ドリル
３）岩状物、コンクリート、及び組積み構造における脆いを加工するコアドリルクラウン
４）食材等をくり抜き加工するためのカッター
Furthermore, the present invention can be applied not only to a core sampler for sampling a feed, but also to a use as a tube forming blade described below.
1) Core drills and hole saws for drilling holes in walls, etc. 2) Blade-replaceable drills used for drilling concrete, etc. 3) Core drill crowns that process brittleness in rocks, concrete, and masonry structures 4) Ingredients Cutter for cutting
そこで、この発明は、上記のコアドリル、ホールソー、コンクリートなどの穿孔用に用いる刃先交換型ドリル、コアドリルクラウン、食材用カッターに用いる刃において、該刃先が磨耗し、変形しても、刃先のみを低コストで交換可能とできる管型形成刃先を開発・提供することにある。 Therefore, the present invention provides a cutting edge replacement drill used for drilling core drills, hole saws, concrete, and the like, a blade used for a core drill crown, and a food cutter. Even when the cutting edge is worn and deformed, only the cutting edge is reduced. The object is to develop and provide a tube-forming blade that can be exchanged at low cost.
この発明による課題を解決するための手段としては、適宜な厚みを有する長方形のステンレス板を素材とし、該ステンレス板の長辺の一辺にレーザー加工により形成されたステンレス板を、丸めて短円筒状の刃先部に形成し、該短円筒状の刃先部を、ステンレス製の採取円筒の外縁部に着脱可能手段により装着したことを特徴とする交換可能な管型形成刃先としたものである。 As a means for solving the problems according to the present invention, a rectangular stainless steel plate having an appropriate thickness is used as a raw material, and a stainless steel plate formed by laser processing on one side of the long side of the stainless steel plate is rounded into a short cylindrical shape. The replaceable tube-shaped blade edge is formed by attaching the short cylindrical blade edge portion to the outer edge portion of the stainless steel sampling cylinder by a detachable means.
この発明によると、採取円筒の外縁部に着脱可能手段により装着したことにより、簡単に刃の交換ができ、また、刃の先端に直接、刃を反復形成する方法よりも安価に刃を付けることが可能となる等のすぐれた効果を奏する。 According to the present invention, the blade can be easily replaced by attaching it to the outer edge of the sampling cylinder by means of detachable means, and the blade can be attached at a lower cost than the method of repeatedly forming the blade directly on the tip of the blade. Excellent effects such as being possible.

The number of cutting edges formed by laser processing on one side of the long side is 14 and the width of the blade is 5 mm. The stainless plate (X) has a plurality of rivet holes (4a). Furthermore, this stainless steel plate (X) uses SUS420J2 and is rounded into a short cylindrical shape and then quenched.
また、ステンレス製の採取円筒（３）の素材は、ＳＵＳ４１０を使用しており、該ステンレス製の採取円筒（３）の一端外縁部に、前記短円筒状の刃先部（１）が嵌挿可能となるよう設ける。さらに、該ステンレス製の採取円筒（３）の外縁部に装着する短円筒状の刃先部（２）とは、着脱可能手段（Ｙ）により装着されるものであり、該着脱可能手段（Ｙ）の一例としては、複数のリベット（４）にて固定するものである。しかし、着脱可能手段（Ｙ）は、リベット（４）に限定されることはない。 The material of the stainless steel sampling cylinder (3) is SUS410, and the short cylindrical cutting edge (1) can be inserted into the outer edge of one end of the stainless steel sampling cylinder (3). Provide to be. Furthermore, the short cylindrical blade tip (2) attached to the outer edge of the stainless steel sampling cylinder (3) is attached by detachable means (Y), and the detachable means (Y) As an example, a plurality of rivets (4) are used for fixing. However, the detachable means (Y) is not limited to the rivet (4).
また、該ステンレス製の採取円筒（３）の他端には、外周面に段部を有する短円柱状の蓋体（５）と着脱可能に嵌着している。該蓋体（５）には、電気ドリル等の駆動源（図示せず）の回転軸（Ｚ）を挿入する差し込み穴（６）を形成し、該蓋体（５）の外周面には、前記回転軸（Ｚ）にステンレス製の採取円筒（３）を固定するネジ（７）を、均等角度（図面では、１２０度毎）の位置からそれぞれ回転軸（Ｚ）に向けて設けている。さらに、採取円筒（３）の他端口縁部の、前記ネジ（７）が位置する均等角度（図面では、１２０度毎）の位置に、ネジ（７）の頭が挿入する，略Ｌ字状の係止溝（８）を形成し、蓋体（５）に設けた前記ネジ（７）の頭を、採取円筒（３）の該係止溝（８）に軸方向に向けて嵌入し、該係止溝の底部に達すると、次に、該軸と直交方向に捩じって固定するものである。 Further, the other end of the stainless steel sampling cylinder (3) is detachably fitted to a short columnar lid (5) having a stepped portion on the outer peripheral surface. The lid (5) is formed with an insertion hole (6) for inserting a rotating shaft (Z) of a drive source (not shown) such as an electric drill, and the outer peripheral surface of the lid (5) Screws (7) for fixing the stainless steel sampling cylinder (3) to the rotating shaft (Z) are provided from the positions at equal angles (in the drawing, every 120 degrees) toward the rotating shaft (Z). Furthermore, the head of the screw (7) is inserted in the same angle (120 degrees in the drawing) at which the screw (7) is located at the other edge of the sampling cylinder (3). The locking groove (8) is formed, and the head of the screw (7) provided on the lid (5) is fitted into the locking groove (8) of the sampling cylinder (3) in the axial direction, When the bottom of the locking groove is reached, it is fixed by twisting in a direction orthogonal to the axis.
