Description

本発明は、岩石、鉄系金属を除く各種廃棄物等の押込み、破砕、積込及び積卸しに使用される破砕機に関する。   The present invention relates to a crusher used for pushing, crushing, loading and unloading various wastes other than rocks and ferrous metals.

従来のバケットを備えた破砕機は、第９図に示すように、バケット１内に油圧モータで回転される回転ドラム２と、回転ドラム２に櫛歯状に並べられた回転刃３と、回転刃３の間を閉塞するように配置された固定刃４を備えると共に、バケット開口部５を覆うように開閉できるバケットカバー６を設けていたが、回転刃３、固定刃４、いずれも、部分的に１つの刃が破損しても回転刃列全部又は固定刃列全部を取り外してからその破損刃を取替なければならない欠点があり、多大の労力と時聞を要していた。
また、バケットカバー６は、被破砕物のつかみ上げや、バケット内からの被破砕物の飛散防止のためバケット開口部５を覆うように開閉するよう形成されていたが、バケットの中まで被破砕物を押し込んで供給することができないので破砕が不充分になる欠点があった。
そこで本発明者は、固定刃を少なくとも複数組の山形状平板に形成して、平板を個々に取替できるようにすると共に、個々の固定刃の山形状の谷部に嵌合して回転する回転刃を個々にドラムの円周面に取り付けて個々に取替できるようにし、固定刃、回転刃のいずれが破損しても、破損刃のみを取付ボルトを介して取替可能とし、また、バケットに設けた４節リンク装置を介してバケットカバーを駆動できるようにすると共に、バケットカバーをバケット内に嵌入できるようにして、被破砕物を回転刃と固定刃の間に押しつけて強力に破砕し、被破砕物の残留を減少させることができるようすることに成功した。
特開２００４−６６２１３号公報 As shown in FIG. 9, a conventional crusher equipped with a bucket has a rotating drum 2 that is rotated by a hydraulic motor in the bucket 1, a rotating blade 3 that is arranged in a comb-like shape on the rotating drum 2, and a rotating blade. While the fixed blade 4 disposed so as to close the space between the blades 3 and the bucket cover 6 that can be opened and closed so as to cover the bucket opening 5 are provided, the rotary blade 3 and the fixed blade 4 are both partially Even if one blade is broken, there is a disadvantage that the broken blade must be replaced after removing the entire rotating blade row or the entire fixed blade row, which requires a great deal of labor and time.
Further, the bucket cover 6 was formed to open and close so as to cover the bucket opening 5 in order to pick up the object to be crushed and prevent the object to be crushed from scattering inside the bucket. There was a drawback that crushing was insufficient because the product could not be pushed in and supplied.
Therefore, the inventor forms fixed blades in at least a plurality of sets of mountain-shaped flat plates so that the flat plates can be individually replaced, and rotates by fitting into the mountain-shaped valleys of the individual fixed blades. Rotating blades can be individually attached to the circumferential surface of the drum so that they can be replaced individually.If either the fixed blade or the rotating blade is damaged, only the damaged blade can be replaced via the mounting bolt. The bucket cover can be driven via a four-bar linkage provided on the bucket, and the bucket cover can be fitted into the bucket, and the object to be crushed is pressed between the rotary blade and the fixed blade to strongly crush. And succeeded in reducing the residue of the material to be crushed.

The bucket cover 30 is pivotally supported by a bracket 200 on the upper surface of the opening 21 of the bucket 20 so that it can be rotated by a cover cylinder 33 via a bell crank 321 and a link 322 constituting a four-bar linkage device.
As shown in FIGS. 2, 3, and 6, the four-bar link device includes a pair of brackets 200 provided on the upper surface of the bucket 20, a pair of bell cranks 321 of a booster rod, a pair of links 322, and a bucket cover. 30, each bell crank 321 is rotatably connected to the bracket 200 of the bucket body at the second connecting portion 3212 at the lower end, and is rotatably connected to the link 322 at the third connecting portion 3213 at the tip. An intermediate first connecting portion 3211 is rotatably connected to the cylinder rod 331 of the cover cylinder 33, and the other end of the link 322 is rotatably connected to the fourth connecting portion 301 of the arm 300 of the bucket cover 30. The fifth cover 302 of the bucket cover 30 fixed to the arm 300 is connected to the bracket 200 of the bucket 20 so as to be freely rotatable.
Further, as shown in FIG. 5, the bucket cover 30 is connected to the pair of brackets 200, 200 of the bucket body so as to be freely rotatable by fifth connection portions 302, 302 provided on the pair of arms 300, 300, The connecting portions 302 and 302 on both sides are directly connected by a counter shaft 34 (intermediate shaft), and are rotatably connected to the lower end of the link 322 by a fourth connecting portion 301 at the upper end of the arm 300.
Therefore, when the crusher is used, the arm 2 of the excavator 1 is driven, the lower end of the bucket 20 is brought close to the object to be crushed 50, and the iron magnets in the crushed object 50 are adsorbed and removed by the electromagnet 40. After that, if a solenoid valve (not shown) provided on the arm 2 is switched and the hydraulic pressure supplied to the bucket cylinder 3 is supplied to the cover cylinder 33, the bell crank 321 is connected via the cylinder rod 331 and the first connecting portion 3211. The second connection portion 3212 rotates around the center, the link 322 is pushed by the third connection portion 3213 at the tip, the lower end of the link 322 pushes the fourth connection portion 301 of the bucket cover 30, and the bucket cover 30 The floating parts around the connecting parts 302 and 302 act as a four-bar link, and the entire bucket cover 30 can be rotated, and the fifth connecting parts 302 and 30 can be rotated. The counter shaft 34 provided, it is possible to correct the unbalance of the load of the object to be crushed 50 striking the left and right tip of the bucket cover 30.
By rotating the bucket cover 30, the object to be crushed 50 is taken into the bucket, and further rotated into the bucket 20 so as to be pressed against the rotating drum 11, and another electromagnetic valve (not shown) provided on the arm 2 is switched. Thus, the hydraulic pressure supplied to the bucket cylinder 3 is supplied to the drive hydraulic motor of the rotary drum 11, and the object 50 is crushed between the rotary blade 12 and the fixed blade 13.
The crushed small pieces to be crushed are discharged from the discharge portion 22 of the bucket 20.
