【0001】[0001]

【産業上の利用分野】[Industrial applications]

この考案は各種の大形の薄鉄板構造物または粗大廃棄物を比較的大きく破砕す る粗破砕装置に関する。 The present invention relates to a coarse crushing device that crushes various large thin iron plate structures or coarse waste relatively large.

【0002】[0002]

【従来の技術】[Prior Art]

従来の粗破砕機の一例として実公昭62−9950号公報に記載されたものが ある。 この公知の粗破砕機は上部後寄りに投入口、下部前寄りに排出口を有する箱型 フレーム内の中程上部寄りとその下部前寄りに横方向の上部破砕軸と下部破砕軸 とを設け、下部破砕軸が上部破砕軸より高速で回転し、この両破砕軸の各破砕刃 でくわえ込んだ被破砕物をその回転速度差で破砕するようにしたものである。 An example of a conventional coarse crusher is described in Japanese Utility Model Publication No. 62-9950. This known coarse crusher is provided with a horizontal upper crushing shaft and a lower crushing shaft in the middle upper part and the lower front part in a box-shaped frame having a charging port in the upper rear part and a discharging port in the lower front part. The lower crushing shaft rotates at a higher speed than the upper crushing shaft, and the objects to be crushed by the crushing blades of both crushing shafts are crushed by the difference in rotation speed.

【0003】 また、破砕刃の間にグレートを介在させて破砕物の寸法を一定以下に揃えるよ うにしたものもある。In addition, there is also one in which a grate is interposed between the crushing blades so that the sizes of the crushed products are made equal to or less than a certain size.

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記実公昭62−9950号公報に記載された粗破砕機は格子板がないので破 砕物の寸法が不規則となる。 また、格子板を設けると、破砕寸法が一定以下となるが、破砕物が粗くて、不 規則なものでもよい場合に格子板を設置するとエネルギーの消費を大きくするの みで、かえって不都合である。 Since the coarse crusher described in Japanese Utility Model Publication No. 62-9950 does not have a grid plate, the size of the crushed product is irregular. In addition, if a grid plate is provided, the crushing size will be less than a certain value, but if the crushed material is coarse and irregular, then installing a grid plate only increases energy consumption, which is rather inconvenient. ..

【0005】 この考案の課題は上記の問題を解決するために不要時には格子板を簡単に不作 用位置につけることができる破砕寸法調整装置を提供することである。An object of the present invention is to provide a crushing size adjusting device which can easily put a lattice plate in an inoperative position when it is not necessary to solve the above problems.

【0006】[0006]

【課題を解決するための手段】[Means for Solving the Problems]

上記の課題を解決する手段として、この考案は粗破砕機における下部破砕軸の 排出口側に格子板を配置して、その一端を軸により上記箱型フレームに回転自在 に取付け、この格子板を回転させる駆動手段を設けた構成とし、格子板の各グレ ートが上記下部破砕軸の各破砕刃の間に入り込んだ定位置から排出方向への格子 板の回動を阻止するロック装置を設け、このロック装置は上記格子板をロックし た状態と、ロックを解除した状態とを選択できる操作装置を有する構成としたも のである。 As a means for solving the above problems, the present invention arranges a lattice plate on the discharge port side of the lower crushing shaft of a coarse crusher, and attach one end of the lattice plate rotatably to the box frame by the shaft. A drive device for rotating the grid plate is provided, and a locking device is provided to prevent rotation of the grid plate in a discharging direction from a fixed position where each grate of the grid plate enters between the crushing blades of the lower crushing shaft. The lock device is configured to have an operating device that can select a locked state and a unlocked state of the lattice plate.

【作用】[Action]

この考案は上記の構成であり投入口から投入した薄鉄板構造物や粗大廃棄物の ような被破砕物は、上下の破砕軸の間にくわえ込まれ、その破砕刃の回転速度差 により破砕されて排出口から排出される。 The present invention has the above-mentioned configuration, and a crushed object such as a thin iron plate structure or coarse waste charged from the charging port is gripped between the upper and lower crushing shafts and crushed by the difference in rotation speed of the crushing blades. Is discharged from the discharge port.

【0008】 上記の破砕作用において、格子板の各グレートが破砕刃の間に入り込んでいる ときは破砕刃とグレートの間を通過する破砕物のみが排出口から排出されるので 破砕物の寸法は一定以下に揃えられる。In the above crushing action, when each grate of the lattice plate is inserted between the crushing blades, only the crushed material passing between the crushing blade and the grate is discharged from the discharge port. It is arranged below a certain level.

【0009】 また、破砕物が粗くて揃わなくてもよい場合は格子板を排出方向に回して各グ レートを各破砕刃の回転圏外の不作用位置にする。 上記の調整操作により、破砕物はグレートにじゃまされることなく排出される ので破砕物は粗くなるが、消費エネルギーは節減される。Further, when the crushed materials are coarse and do not need to be aligned, the grid plate is rotated in the discharge direction to bring each grate to an inoperative position of each crushing blade outside the rotation range. By the above adjustment operation, the crushed material is discharged without being disturbed by the grate, so the crushed material becomes coarse, but energy consumption is reduced.

In this state, while the crushing shafts 5 and 6 are rotated in the directions of the arrows in FIG. 3 by the power sources 11 and 12, the crushed object is introduced from the charging port 2, the crushed object descends on the upper surface of the press wing 26. While being crushed by the crushing blades 9 and 10, they are sheared and crushed by the speed difference between the crushing shafts 5 and 6. At this time, when the object to be crushed is hard to be comparatively crushed, such as compacted iron scrap, the hydraulic cylinder 30 is operated to rotate the press wing 26 toward the crushing shafts 5 and 6 and crush it while crushing. .. In this case, the coarse crushed material is also discharged from the discharge port 3 as it is.
