従来 の ロ ー ル摩砕刃 は 刃 先 の 耐摩耗性、 破砕効 率 お よ び製品 の 回 収率等 の 点 で 必 ず し も 満 足 す ベ き も の で は な か っ た 。 本発 明 者 は こ れ ら の 点 を 改 良 す る た め に 上面 が扁 平 な ひ し 形 を な す 角 柱体 の 各 側 面 に 上面 の り よ う 線部 と 平行 な 左 右 の 切 欠溝 を 設 け る こ と に よ り 、 上 面 の り ょ う 線部分、 そ れ ら の 先端 の 鋭角 交差部分 な ら び に 切欠溝 の 先端部 の 鋭角 交差部分 に 夫 々 刃先 を 形成 し た ロ ー ル摩砕 刃 を 提案 し た （ た と え ば、 特騮昭 5 9 — 第 0 3 7 4 3 1号 、 特公昭 6 2— 5〗 5 6 9 号、 お よ び 本願添付図面第 7 図参 照 ） 。  Conventional roll milling blades are not necessarily satisfactory in terms of the wear resistance of the cutting edge, crushing efficiency, and product recovery. In order to improve these points, the present inventor tried to improve these points on each side of a rectangular prism with a flat top and a left and right side parallel to the line on the top. By setting the notch groove, the cutting edge is formed at the top of the stub line, at the sharp intersection of the tip of the upper surface, and at the sharp intersection of the tip of the notch groove. Roll grinding blades (for example, Japanese Patent Publication No. 59-No. 073431, Japanese Patent Publication No. 62-5-569, and attached to the present application) See Figure 7).
こ の よ う な ロ ー ル摩砕刃 に よ れ ば、 そ の 角 柱体 の 各 部 に 形成 さ れ る 前記 の 刃先 の 複合 作用 に よ つ て 著 し く 改善 さ れた 破砕お よ び摩砕効率が得 ら れ、 ま た 従来 の 刃片 に 比較 し て そ の 耐摩耗性 も 著 し く 向上す る 。 According to such a roll milling blade, the above-mentioned combined action of the cutting edges formed in each part of the prismatic body is achieved. Thus, a significantly improved crushing and grinding efficiency is obtained, and its wear resistance is also significantly improved as compared with the conventional cutting blade.
こ の よ う な 性能 の 向上に よ っ て、 前記改良 さ れ た ロ ー ル摩砕刃 は一般的な破砕 も し く は摩砕用 途 に は も と よ り 、 た と え ば従来 の 回 転刃 で は不可能 と さ れて い た 廃タ イ ャ 等 のゴ ム成形品廃材の 粉碎 に よ っ て燃料 も し く は ア ス フ ァ ル ト 混入材等 と し て 有用 な ゴ ム 粒子 を 得 る こ と も 可能 と な っ た。  Due to this improved performance, the improved roll milling blade is more suitable for conventional crushing or milling applications than, for example, conventional crushing. The grinding of waste rubber molded products such as waste tires, which was considered impossible with rotary blades, is useful as a fuel or as a material mixed with asbestos by grinding. It is also possible to obtain microparticles.
し か し こ の よ う に し て破砕可能 な対象が拡大 す る に つ れて 刃先 の 形状 に さ ら に一層 の 改善 が要求 さ れ る こ と が判 明 し た 。  However, it has been found that as the crushable object expands in this way, further improvements in the shape of the cutting edge are required.
す な わ ち 前記 ロ ー ル摩碎刃 に よ れ ば、 刃片 の 形 状 を 大 き く し か つ切欠 さ れ る 溝 を 深 く す る こ と に よ っ て た と え ば廃 タ イ ヤ 力、 ら 任意 の 粒径 の ゴ ム 粒 子 を 得 る こ と がで き る が、 切欠溝を 深 く 大 き く 形 成す る と 構造強度が低下 し て 刃片 に 破損 を 生 じ て 交換頻度が高 く な る た め 一定 の 制約が あ っ た 。  That is, according to the above-mentioned roll grinding blade, the shape of the blade piece is made large and the notched groove is deepened. Rubber particles of any particle size can be obtained from ear force, etc.However, if the notch groove is formed deep and large, the structural strength is reduced and the cutting piece is damaged. There was a certain restriction because the frequency of replacement became high.
し た が っ て 、 こ の 発明 の 目 的 は前記形式 の 口 一 ル摩砕刃 を さ ら に改善 し 刃先 の 食込み や得 ら れる 破砕片 の 粒度 に閬 し て切欠溝 の深 さ を 任意 に 設定 し て も 刃 の 耐衝撃性 に は ほ と ん ど影響 の な い 高強 度 の ロ ー ル破砕刃 を 提供す る こ と に あ る 。  Therefore, the purpose of the present invention is to further improve the above-mentioned mouth grinding blade of the type described above, and to set the depth of the notch groove arbitrarily according to the bite of the blade edge and the grain size of the obtained crushed piece. It is possible to provide a high-strength roll crushing blade which has almost no effect on the impact resistance of the blade even if it is set to.

The crushing blade is a crushing blade which is mounted in a predetermined arrangement along the direction of the axis of the cylinder and has a polygonal prism having an almost flat upper surface and a polygonal shape. On its upper surface, there are left and right horizontal lines that cross at an acute angle in the roll rotation direction, and on its side surface, the tip is located below the respective horizontal lines parallel to the upper surface. At least a part of the rear part is cut away from the part to the rear part to provide a notched groove, so that the upper surface of the prism body is on the left and right sides. A tip blade is provided at an acute angle portion of the crossing tip of the line portion, a front face blade is provided at a tip portion where the left and right cutout grooves intersect with each other, and a front edge is provided at a right and left edge of the upper surface of the prism.

It works essentially the same as a crushing blade. In particular, since there is no such notched groove in the rear part of the prism, the entire blade is remarkably enhanced in strength, and the blade during crushing is sharpened. Damage is prevented.

However, if necessary, a prismatic body as shown in FIG. 6 may be used. A plurality of notches 4, 4,... Are provided at predetermined intervals along the height direction of 8 to form a multi-layer blade structure in which the cutting blades are layered in the height direction. You can do that too.
第 7 図 に 示す 従来例 と の 対比か ら も 明 ら か な よ う に 、 重層 刃 に お い て は 刃 高が高 い の で 破損 し や す く 特 に 耐摩耗性 に 優れ た 超硬合金 に よ つ て 刃 先 を 形成 し て 硬度 の 大 き な 破砕物 を 破砕 す る 用 途 の 場合 に は 、 切欠溝 4 、 4 、 … 等 の 形成 に よ っ て 構 遣強度が著 し く 低下 し て 実際上作業が不可 能 な場 合が あ る 。 こ の よ う な場合、 第 6 図示 の 実施例 の よ う に 切欠溝 4 、 4 、 … を ロ ー ル画転方向 の 前方 部 （ 図中 左方 ） の み に 限定 し て 形成す る こ と に よ り そ の 強度が著 し く 改善 さ れ る 。 As is evident from the comparison with the conventional example shown in Fig. 7, the carbide blades, which are easily broken and especially excellent in wear resistance, because the blade height of the multilayer blade is high. In the case of crushing crushed material having a high hardness by forming a cutting edge by using an alloy, it is possible to form the notch grooves 4, 4, ..., etc. In some cases, the working strength may be so low that work is practically impossible. In such a case, as in the embodiment shown in FIG. 6, the cutout grooves 4, 4,... Are limited to only the front part (left side in the figure) in the roll image transfer direction. As a result, the strength is significantly improved.
