JP 2000-325807 A

しかしながらこれら従来構造の場合、上記スクリーン部材は平坦な板材に破砕粒度調節用の複数個の円形、長円形又は四角状の通穴を形成してなり、このため、上記隣り合う回転刃の間に存在する複数個の各間隙とスクリーン部材との間に略三角形状の対向空間が生じ、この空間の存在により回転刃により生ずる被破砕物の押圧排出力が小さく、特に被破砕物が粘りのあるもの、付着し易いもの、溶け易いものにあっては、この不充分な押圧排出力により被破砕物が通穴を円滑に通過することができなかったり、被破砕物が通穴の近傍に付着したりして、著しく破砕効率を低下させることがあり、また、目詰まりに伴うスクリーン部材の掃除作業、交換作業も相まって破砕作業能率の低下を余儀なくされることがあるという不都合を有している。 However, in the case of these conventional structures, the screen member is formed by forming a plurality of circular, oval or square through-holes for adjusting the crushing particle size on a flat plate material, and therefore, between the adjacent rotary blades. A substantially triangular facing space is formed between each of the plurality of existing gaps and the screen member, and the existence of this space reduces the pressure discharge force of the object to be crushed by the rotary blade, and the object to be crushed is particularly sticky. For objects that are easy to adhere, those that are easy to melt, this insufficient pressure discharge force prevents the material to be crushed from passing smoothly through the through-hole, or the material to be crushed adheres to the vicinity of the through-hole. However, there is a disadvantage that the crushing efficiency may be significantly reduced, and the crushing work efficiency may be reduced due to the cleaning work and replacement work of the screen member due to clogging. .

本発明はこれらの不都合を解決することを目的とするもので、本発明のうちで、請求項１記載の発明は、破砕機体内に破砕室部を配設し、該破砕室部内に回転軸を横設し、該回転軸に回転ロータを配設し、該回転ロータの外周面に複数個の回転刃を並列状に配設し、該破砕機体に複数個の通穴をもつ板材からなるスクリーン部材を該回転刃の回転軌跡の下方位置に配設し、該破砕機体に該回転刃と協動して被破砕物を剪断破砕する固定刃を配設してなり、上記スクリーン部材を上記隣り合う回転刃の間に存在する複数個の各対向空間内に没入可能な連続的に並列する複数個の波条没入部からなる略波板形状に形成してなることを特徴とする破砕機にある。 The present invention aims to solve these disadvantages. Among the present inventions, the invention according to claim 1 is provided with a crushing chamber provided in a crushing machine, and a rotating shaft in the crushing chamber. The rotary rotor is disposed on the rotary shaft, a plurality of rotary blades are arranged in parallel on the outer peripheral surface of the rotary rotor, and the crushing machine body is made of a plate material having a plurality of through holes. A screen member is disposed at a position below the rotation trajectory of the rotary blade, and a fixed blade for shearing and crushing an object to be crushed in cooperation with the rotary blade is disposed on the crushing machine body. A crusher characterized by being formed into a substantially corrugated plate shape composed of a plurality of continuous wave immersing portions that can be immersed in a plurality of opposing spaces existing between adjacent rotary blades. It is in.

又、請求項２記載の発明は、上記回転刃は正方形断面の角柱状に形成され、該回転刃の表面の四個の稜線のうちの略Ｖ状をなして隣り合う二つの稜線を刃部とすることを特徴とするものであり、又、請求項３記載の発明は、上記通穴はジグザグ形状に形成されていることを特徴とするものである。 According to a second aspect of the present invention, the rotary blade is formed in a square column shape having a square cross section, and two adjacent ridge lines that form a substantially V shape out of the four ridge lines on the surface of the rotary blade are blade portions. The invention according to claim 3 is characterized in that the through hole is formed in a zigzag shape.

本発明は上述の如く、請求項１記載の発明にあっては、破砕機体内の破砕室部にフィルム、ランナ、プラスチックラップ等の都市ゴミや産業廃棄物等の被破砕物を投入し、破砕室部において、回転ロータの回転軸の回転により複数個の回転刃は回転し、この回転刃の回転により破砕機体に取り付けられた固定刃との協働により被破砕物を剪断破砕することになり、破砕された被破砕物はスクリーン部材を通って落下し、落下しなかった大きな被破砕物は再び上方にまわってから再度剪断破砕され、このようにして被破砕物の剪断破砕が行われることになり、この際、上記スクリーン部材を上記隣り合う回転刃の間に存在する複数個の各対向空間内に没入可能な連続的に並列する複数個の波条没入部からなる略波板形状に形成してなるから、隣り合う回転刃の間に存在する複数個の各間隙とスクリーン部材との間に生ずる各対向空間内に波条没入部が没入し、この波条没入部が対向空間を埋めることにより回転刃により生ずる被破砕物の押圧排出力を高く保つことができ、柔らかく、付着し易く、溶け易いような被破砕物であっても、通穴を円滑に通過することができ、破砕効率を高めることができる。 As described above, the present invention is the invention described in claim 1, in which a crushed object such as a municipal waste such as a film, a runner, and a plastic wrap or an industrial waste is put into a crushing chamber in a crushing machine, In the chamber, the plurality of rotary blades rotate by the rotation of the rotary shaft of the rotary rotor, and the rotation of the rotary blades shears and crushes the object to be crushed in cooperation with the fixed blade attached to the crusher body. The crushed material falls through the screen member, and the large crushed material that has not fallen is turned upward again and then sheared and crushed again. In this case, the screen member is formed into a substantially corrugated plate shape composed of a plurality of continuously waved immersion parts that can be immersed in a plurality of opposing spaces existing between the adjacent rotary blades. Because it is formed, next A wave immersion part is immersed in each opposing space generated between the plurality of gaps existing between the rotating blades and the screen member, and the wave immersion part is generated by the rotary blade by filling the opposing space. The pressing and discharging force of the object to be crushed can be kept high, and even the object to be crushed that is soft, easy to adhere and easily melt can pass through the through hole smoothly and increase the crushing efficiency. .

又、請求項２記載の発明にあっては、上記回転刃は正方形断面の角柱状に形成され、回転刃の表面の四個の稜線のうちの略Ｖ状をなして隣り合う二つの稜線を刃部としているから、回転刃とスクリーン部材との間の隙間を可及的に小さくすることができ、これにより回転刃により生ずる被破砕物の押圧排出力を高く保つことができ、被破砕物の通過がより円滑に行われ、一層破砕効率を高めることができ、又、請求項３記載の発明にあっては、上記通穴はジグザグ形状に形成されているので、破砕粒度の大きい被破砕物を良好に破砕することができる。 In the invention described in claim 2, the rotary blade is formed in a prismatic shape having a square cross section, and two adjacent ridgelines are formed in a substantially V shape among the four ridgelines on the surface of the rotary blade. Since the blade portion is used, the gap between the rotary blade and the screen member can be made as small as possible, and thus the pressing and discharging force of the object to be crushed generated by the rotating blade can be kept high. Can be made smoother and the crushing efficiency can be further improved. In the invention according to claim 3, since the through hole is formed in a zigzag shape, the crushing object having a large crushing particle size can be obtained. Goods can be crushed well.

A plurality of rotary blades 6 are arranged on the outer peripheral surface of the rotary rotor 5 in a spiral parallel manner in the axial direction, and the screen member 7 is made of a plate material having a plurality of circular through holes 7a in the crushing machine body 1. Is disposed at a position below the rotation locus of the rotary blade 6, and a fixed blade 8 that shears and crushes the object to be crushed in cooperation with the rotary blade 6 is arranged in the crushing machine body 1.

この場合、図３、図４の如く、上記回転刃６は正方形断面の角柱状に形成され、回転刃６の表面の四個の稜線のうちの略Ｖ状をなして隣り合う二つの稜線を刃部６ａ・６ａとしている。 In this case, as shown in FIGS. 3 and 4, the rotary blade 6 is formed in a square column shape having a square cross section, and two adjacent ridgelines are formed in a substantially V shape among the four ridgelines on the surface of the rotary blade 6. The blade portions 6a and 6a are used.

又、この場合、図４、図５の如く、上記スクリーン部材７は、上記隣り合う回転刃６の間に存在する複数個の略三角形状の各対向空間Ｒ内に回転刃６の刃部６ａ・６ａとの間に隙間Ｓ・Ｓを存して没入可能な連続的に並列する断面略Ｖ条の複数個の波条没入部７ｂ・７ｂ・・・からなる略波板形状に形成され、このスクリーン部材７を左右の湾曲杆９ａ・９ａ及び上下の枠杆９ｂ・９ｃからなる支持枠９に取り付け、左右の湾曲杆９ａ・９ａ間に支持軸９ｄを架設し、支持軸９ｄを破砕機体１に枢着連結し、他方の枠杆９ｂを取付ボルト９ｅにより着脱自在に取り付けるように構成している。 In this case, as shown in FIGS. 4 and 5, the screen member 7 has a blade portion 6 a of the rotary blade 6 in each of a plurality of substantially triangular opposing spaces R existing between the adjacent rotary blades 6. -It is formed in a substantially corrugated plate shape composed of a plurality of wave immersing portions 7b, 7b,. The screen member 7 is attached to a support frame 9 including left and right curved rods 9a and 9a and upper and lower frame rods 9b and 9c, and a support shaft 9d is installed between the left and right curved rods 9a and 9a. The other frame rod 9b is detachably attached by a mounting bolt 9e.

１０は押送部材であって、図示省略の往復動機構により往復運動しつつ前進動作し、被破砕物Ｗを押送部材１０により回転ロータ５に向けて押し送りするように構成している。 Reference numeral 10 denotes a pushing member, which is configured to move forward while being reciprocated by a reciprocating mechanism (not shown), and push the object to be crushed W toward the rotating rotor 5 by the pushing member 10.

この実施の第一形態例は上記構成であるから、図１の如く、人為的又は自動的に、破砕機体１内の破砕室部２に投入口部３を介して、フィルム、ランナ、プラスチックラップ等の都市ゴミや産業廃棄物等の被破砕物Ｗを投入し、押送部材９を往復動させて被破砕物Ｗを破砕室部２に押送し、破砕室部２において、回転ロータ５の回転軸４の回転により複数個の回転刃６は図中矢印方向の時計廻りに回転し、この回転刃６の回転により破砕機体１に取り付けられた固定刃６との協働により被破砕物Ｗを剪断破砕することになり、破砕された被破砕物Ｗはスクリーン部材７を通って落下し、落下しなかった大きな被破砕物Ｗは再び上方にまわってから再度剪断破砕され、このようにして被破砕物Ｗの剪断破砕が行われることになる。 Since the first embodiment of the present embodiment has the above-described configuration, as shown in FIG. 1, a film, a runner, and a plastic wrap are artificially or automatically connected to the crushing chamber portion 2 in the crusher body 1 through the inlet port portion 3. Waste to be crushed, such as municipal waste and industrial waste, and the like, and the pushing member 9 is reciprocated to push the crushed material W to the crushing chamber 2. In the crushing chamber 2, the rotating rotor 5 rotates. The plurality of rotary blades 6 are rotated clockwise in the direction of the arrow in the drawing by the rotation of the shaft 4, and the object W to be crushed is cooperated with the fixed blade 6 attached to the crusher body 1 by the rotation of the rotary blade 6. The crushed object W falls through the screen member 7 and the large crushed object W that has not fallen is turned upward again and then sheared and crushed again. Shear crushing of the crushed material W is performed.

又、この場合、上記回転刃６は正方形断面の角柱状に形成され、回転刃６の表面の四個の稜線のうちの略Ｖ状をなして隣り合う二つの稜線を刃部６ａとしているから、回転刃６とスクリーン部材７との間の隙間Ｓを可及的に小さくすることができ、これにより回転刃６により生ずる被破砕物Ｗの押圧排出力を高く保つことができ、被破砕物Ｗの通過がより円滑に行われ、一層破砕効率を高めることができる。 Further, in this case, the rotary blade 6 is formed in a square column shape having a square cross section, and two adjacent ridge lines of the four ridge lines on the surface of the rotary blade 6 are used as the blade portion 6a. The gap S between the rotary blade 6 and the screen member 7 can be made as small as possible, whereby the pressure discharge force of the object to be crushed W generated by the rotary blade 6 can be kept high. The passage of W is performed more smoothly, and the crushing efficiency can be further increased.

図６の第二形態例は別例構造を示し、この場合、上記通穴７ａの形状を回転方向に延びる長円形状に形成している。 The second embodiment shown in FIG. 6 shows another structure. In this case, the shape of the through hole 7a is formed in an oval shape extending in the rotation direction.

この第二形態例にあっても、上記第一形態例と同様な作用効果を得ることができると共に被破砕物Ｗの内容によっては被破砕物Ｗの通過がより一層円滑に行われ、破砕効率を高めることができる。 Even in this second embodiment, the same effects as the first embodiment can be obtained, and depending on the contents of the object to be crushed W, the object to be crushed W can be passed more smoothly, and the crushing efficiency can be improved. Can be increased.

図７の第三形態例は別例構造を示し、この場合、上記通穴７ａの形状を稲妻に似たジグザク形状に形成している。 The third embodiment shown in FIG. 7 shows another structure. In this case, the shape of the through hole 7a is formed in a zigzag shape similar to lightning.
