備が完了する。B. Prior Art The method for testing the crushability of coal, etc. is specified in JIS M8801, and a hard glove crushability tester is used for the test. This testing machine has a crushing chamber shown in FIG. 2, a steel ball, and a top ring (not shown) that rotates while holding down the steel ball from above. First, eight steel balls were arranged at equal intervals in this grinding chamber, and then 50 g of a sample adjusted to a specific particle size was placed in the grinding chamber and averaged. The top spring is then placed on top of the steel ball and is ready for crushing.
ハ 考案が解決しようとする問題点
しかし、スチールボールが動き易いためスチー
ルボール及び試料のセツトに手間がかかり熟練を
要していた。C. Problems that the invention aims to solve However, since the steel ball moves easily, setting up the steel ball and sample is time-consuming and requires skill.
ニ 問題を解決するための手段
本考案者等は、熟練を要さないで迅速にスチー
ルボールと試料をセツトできる補助具について実
験を行ない、本考案に到達した。D. Means for solving the problem The inventors of the present invention conducted experiments on an auxiliary tool that can quickly set a steel ball and a sample without requiring any skill, and arrived at the present invention.
即ち、本考案は、円板の中心には円筒状の試料
投入部を備え、かつ該円板の同心円上に等間隔に
並んだ８個の円形の切り欠き部を備えてなるハー
ドグローブ試験機用試料装填補助具を提供するも
のである。 That is, the present invention provides a hard glove tester comprising a cylindrical sample input part in the center of a disk and eight circular notches arranged at equal intervals on a concentric circle of the disk. The present invention provides a sample loading aid for
第１図に示すものは、その実施例であつて、１
は円板であり、その中心部には試料投入用の円筒
２を有し、その囲りにはスチールボール５の頭と
嵌合するための８個の円形の切り欠き部３が同心
円上に等間隔に設けられている。 What is shown in FIG.
is a disc, which has a cylinder 2 for introducing a sample in its center, and around it are eight circular notches 3 arranged concentrically to fit the heads of steel balls 5. They are placed at equal intervals.
次ぎに、この補助具を用いた場合のスチールボ
ール及び試料のセツトについて述べる。 Next, we will discuss how to set up the steel ball and sample when using this auxiliary tool.
まず、粉砕室４にスチールボール８個をほぼ等
間隔に並べ、次いでスチールボール５の上に本考
案の補助具を載せ、８個の円形の切り欠き部３の
それぞれからスチールボール５の頭がのぞくよう
にスチールボール５を移動させる。 First, eight steel balls are arranged at approximately equal intervals in the crushing chamber 4, then the auxiliary tool of the present invention is placed on top of the steel balls 5, and the heads of the steel balls 5 are inserted through each of the eight circular notches 3. The steel ball 5 is moved so as to peek out.
次いで、試料50gを試料投入用の円筒２につぎ
込んだのち該補助具を静かに取り除き、試料６の
表面を平らにならしトツプリングをスチールボー
ル５の上に載せて粉砕の準備が完了する。 Next, after pouring 50 g of the sample into the sample injection cylinder 2, the auxiliary tool is gently removed, the surface of the sample 6 is leveled, and the top ring is placed on the steel ball 5, completing preparations for crushing.
