Description

【０００１】
【発明の属する技術分野】
本発明は、壁破砕機に関するものである。
【０００２】
【従来の技術】
従来、油圧、空気圧等を利用して裁断刃を進退作動させ、受刃との間に狭持した壁体を裁断破砕する壁破砕機は、水平方向に伸延するフレームの一端側に受刃を固定配設すると共に、他端側に裁断刃を進退自在に配設し、裁断刃を受刃方向に前進させていくことによって両刃間の壁体を裁断破砕する構成となっていた。
【０００３】
かかる壁破砕機は、裁断刃を受刃方向に前進させて壁体を狭圧するものであるが、この際に、裁断刃には下方への応力が働き、その反力として受刃と裁断刃との間に橋架された状態のフレームが反り気味になってしまうので、フレームに過度の負荷がかかると共に、受刃に対する裁断刃の押圧応力が減殺されて、壁体に対して十分な狭圧力をかけることができないという欠点があった。
【０００４】
そこで、実公平２−３２７５８号公報に開示されているように、間隔を隔てて並設した左右２枚の板状体でフレームを構成すると共に、裁断刃の上面に前記フレームの両板状体間を挿通するガイド杆を立設し、同ガイド杆の上端部に前記フレームに沿って摺動自在なコロを軸支することにより、フレームを裁断刃とコロとで上下から挟んで、裁断刃に対する下方への応力によってフレームが反ることを防止可能とした壁破砕機が提案されている（特許文献１参照。）。
【０００５】
特に、上記実公平２−３２７５８号公報に開示された壁破砕機においては、裁断刃の先端を左右の板刃で構成し、裁断刃の集中応力を高めて、壁体に集中的に押圧力がかかるようにして受刃の左右の板刃との摺動によって壁体の破砕裁断を行うようにしている。

【発明が解決しようとする課題】
しかし、上記した壁破砕機においては、ガイド杆を介して連設した裁断刃とコロとでフレームを挟む構成によってフレームの反りは防止できるものの、裁断刃先端の左右の板刃が壁体へ食い込み壁体を破砕し裁断する時に、破砕された壁組成物が裁断刃先端の左右の板刃間に充填された状態となり、裁断刃の集中応力が低下し壁体に集中的に押圧力がかからないようになり、結果的には裁断刃が壁体へ食い込みにくくなり破砕効率を低下させることになっていた。
【０００８】
【課題を解決するための手段】
そこで、本発明は、間隔を隔てて並設した左右２枚の板状体でガイドフレームを構成すると共に、同ガイドフレームの一端に受刃を設け、他端にシリンダを連設し、シリンダロッドの先端に受刃内面を摺動しながら裁断機能を果たす裁断刃を進退自在に設け、同裁断刃の上面には、前記ガイドフレームの両板状体間を挿通するガイド杆を立設し、同ガイド杆の上端部に前記ガイドフレームに沿って摺動自在のコロを軸支してなる壁破砕機において、前記受刃は左右に配した左右受板刃で構成すると共に、前記裁断刃は左右に配した左右裁断板刃で構成し、左右裁断板刃の中央空間部に、前記受刃に向かって突出させた先端を前記左右裁断板刃の先端縁よりも後方に位置させ、前記先端に向かって一定勾配とした傾斜状の上下面で側面視くさび状とした山形刃を介設し、この山形刃の傾斜状の上下面と左右裁断板刃の内側面とのなす角度を直角としたことを特徴とする壁破砕機を提供せんとするものである。
【０００９】
【発明の実施の形態】
本発明は、受刃と、受刃に向かって進退自在な裁断刃との間で壁体を狭圧し、両刃の鋏機能と押圧破砕機能とによって壁体を切削・圧潰する壁破砕機である。そのため、本壁破砕機においては、間隔を隔てて並設した左右２枚の板状体によりガイドフレームを構成し、同ガイドフレームの一端に受刃を設けると共に、他端にシリンダを連設し、同シリンダのシリンダロッドの先端に裁断刃を設けており、シリンダによって裁断刃を受刃に向かって押し出して、裁断刃を受刃内面に沿って摺動させるようにしている。従って、壁体の破砕時には、両刃が前述した鋏機能と押圧破砕機能とを果たし、両刃間の壁体を切削すると共に圧潰して、壁体を破砕する。
【００１０】
しかも、裁断刃の上面には、前記ガイドフレームの両板状体間を挿通するガイド杆を立設し、さらに、同ガイド杆の上端部には、前記ガイドフレームに沿って摺動自在なコロを軸支しているため、裁断刃がシリンダによって進退する際には、同裁断刃の動きと連動してコロがガイドフレーム上を摺動する。
【００１１】
そのため、ガイドフレームは、ガイド杆を介して上下に連設した裁断刃とコロとによって常に上下側から挟まれることとなり、裁断刃の前進作動によってガイドフレームに上方湾曲方向への応力がかかり、ガイドフレームがシリンダロッドとは反対方向へ反りそうになっても、ガイドフレームを裁断刃とコロとによって上下側から狭圧して、その反りを矯正することができる。
【００１２】
さらには、本実施の形態では、上記したような壁破砕機において、受刃を左右に配した左右受板刃で構成すると共に、裁断刃を左右に配した左右裁断板刃で構成し、左右裁断板刃の中央空間部に、受刃に向かって先端を突出させたくさび状の山形刃を介設している。
【００１３】
従って、壁体を破砕するに際しては、裁断刃による壁体への押圧食込みと共に、左右受板刃と左右裁断板刃との摺動よる鋏機能によって壁体を切削するものであるが、それと共に裁断刃が壁体に押圧されて食込む際に左右裁断板刃間に残留した壁体部分を先端の尖った山形刃の押圧破砕機能によって圧潰し、このように切削、圧潰されて粉砕された壁体組成物は山形刃の上下の傾斜面に沿って刃の外部に排出され左右受板刃や左右裁断板刃内に溜まらず壁体の破砕を効率よく速やかに行うことができるものである。
【００１４】
【実施例】
以下、本発明に係る壁破砕機の一実施例を図面に基づき説明する。
【００１５】
図１は本発明にかかる壁破砕機の一実施例の斜視図であり、図示するように、本実施例における壁破砕機Ａは、壁体を切削・圧潰するための受刃１及び裁断刃２と、受刃１に向かって裁断刃２を進退させるシリンダ３と、前記受刃１、裁断刃２、及びシリンダ３を支持するガイドフレーム４とからなる。
【００１６】
ガイドフレーム４は、前後方向に伸延する左右２枚の板状体５,５を間隔を隔てて起立状態に並設した構成としており、先端下部に受刃１を垂設する一方、後端下部にシリンダ３を垂設している。
【００１７】
特に、シリンダ３は、前後方向に伸延するシリンダ本体６の先端部をガイドフレーム４の後端下部に取り付けて、シリンダロッド７が前記ガイドフレーム４の下方を進退運動するようにしており、このシリンダロッド７の先端に裁断刃２を連設することによって、同裁断刃２を、ガイドフレーム４の先端下部に垂設した受刃１に向かって自在に進退できるようにしている。
【００１８】
しかも、裁断刃２の上面には、前記ガイドフレーム４の両板状体５,５間を挿通するガイド杆８を立設しており、同ガイド杆８の上端部に、前記ガイドフレーム４の上面に沿って摺動自在なコロ９を軸支している。従って、ガイドフレーム４にはシリンダ３が連設し、同シリンダ３には裁断刃２が連設し、同裁断刃２にはガイド杆８が連設し、同ガイド杆８にはコロ９が連設することとなり、しかも、同コロ９は前記裁断刃２と共働してガイドフレーム４を両側から狭持することとなる。そのため、壁体の破砕時に、裁断刃２を支持するシリンダロッド７に対して下方への狭圧応力が働き、その反力を受けたガイドフレーム４が上方に反りそうになったとしても、同ガイドフレーム４の上面に当接するコロ９によりガイドフレーム４を下方へ押さえて、ガイドフレーム４が上方に反らないようにすることができる。図中、10は把持棒、11はコロ９の枢軸、12はシリンダ３とガイドフレーム４との連結を補強する補強用リブである。
【００１９】
上記構成よりなる壁破砕機Ａにおいて本発明の特徴となるのは、受刃１と対になって壁体を挟み、同壁体を切削・圧潰する裁断刃２の形状である。そこで、受刃１及び裁断刃２の構成を以下に説明する。
【００２０】
図２は、本発明に係る壁破砕機Ａの受刃１及び裁断刃２の構成を示す模式図であり、図示するように、受刃１は、略矩形板状に形成した左右受板刃13,13を起立状態に並設すると共に、同左右受板刃13,13の上端間を、同じく略矩形板状に形成した上部連結体14で連結して、正面視略門状に形成している。
【００２１】
一方、裁断刃２は、略矩形板状に形成した左右裁断板刃15,15を起立状態に並設すると共に、同左右裁断板刃15,15の後端間を、同じく略矩形板状に形成した後部連結体16で連結して、平面視略門状に形成している。そして、シリンダ３によって受刃１の方向へと押し出された際には、左右裁断板刃15,15の外側面が左右受板刃13,13の内側面に沿って摺動して、受刃１の左右受板刃13,13間に挿入されるようにしている。
【００２２】
しかも、左右裁断板刃15,15間に形成される中央空間部Ｓには、受刃１に向かって先端を突出させた側面視くさび状の山形刃17を介設しており、山形刃17の上下面は先端に向かって一定勾配の傾斜状に形成されている。特に、同山形刃17の先端は前記左右裁断板刃15,15の先端縁よりも後方に位置するように形成している。このように、山形刃17の先端を左右裁断板刃15,15の先端よりも後方に位置させているので、壁体を破砕する際には、山形刃17よりも先に左右裁断板刃15,15が壁体と当接することとなり、しかも山形刃17の上下面は傾斜状に形成されているため破砕された壁体の粉砕粉や破砕屑は山形刃17の傾斜面に沿って刃外部に排出されるので刃内部に残留されず円滑な破砕作業が遂行できる効果がある。
【００２３】
また、山形刃17は、左右裁断板刃15,15及び後部連結体16とは別体に形成して、その後、左右裁断板刃15,15間に挿入固定するようにしており、同山形刃17を固定するに際しては、山形刃17の上下傾斜面の中途部に後部連結体16に向かって陥入する連結具取付凹部18をそれぞれ形成し、同連結具取付凹部18にビスやボルト等の連結具19を挿入して、前記後部連結体16に固定するようにしている。
【００２４】
従って、連結具19は前記連結具取付凹部18の内部に納まることとなり、山形刃17の上下傾斜面から突出することがない。そのため、壁体の破砕時に、連結具19が直に壁体と衝突して破損するのを防止することができ、かかる連結具19の破損によって山形刃17の取付が緩むのを防止することができる。
【００２５】
受刃１及び裁断刃２は上記構成よりなり、かかる受刃１及び裁断刃２を用いた本壁破砕機Ａによって壁体を破砕する際には、受刃１と裁断刃２との間に挟まれた壁体は、まず、裁断刃２が受刃１方向へと進出するのに伴って左右裁断板刃15,15の前端面と当接し、左受板刃13と左裁断板刃15、及び右受板刃13と右裁断板刃15による鋏機能によってその当接面を切削される。そして、切削されることなく左右裁断板刃15,15間に残留した壁体部分は、次に、左右裁断板刃15,15間に介設されている先端の尖った山形刃17へと到達して、同山形刃17の押圧破砕機能により圧潰される。このとき、山形刃17によって圧潰される壁体は、左右裁断板刃15,15によって予め所定間隔、すなわち、左裁断板刃15と右裁断板刃15との間隔に切り出されているので、容易に圧潰することができる。
【００２６】
このように、本壁破砕機Ａにおいては、受刃１と裁断刃２の鋏機能及び押圧破砕機能を利用して壁体を破砕するので、効果的に壁体を破砕することができる。しかも、左右裁断板刃15,15を同左右裁断板刃15,15間に介設した山形刃17よりも先方に突出させているので、壁体を破砕するに際しては、山形刃17よりも先に左右裁断板刃15,15が壁体に当接して壁体を所定間隔に切り出し、所定間隔に切り出されて破砕しやすくなった壁体を先端の尖った山形刃17が圧潰することになるので、破砕の効率を向上させることができると共に、先端が尖っていて摩耗しやすい山形刃17への負担を軽減することができる。
【００２７】
さらに、山形刃17は、前述したように側面視くさび状に形成していて、平面視くさび状に形成した場合と比較すると、左右裁断板刃15,15となす角度（山形刃17の上下斜面が左右裁断板刃15,15の内側面となす角度）が略直角なので、破砕された壁体が山形刃17と左右裁断板刃15,15との間に詰まりにくい。
【００２８】
しかも、山形刃17の上下面は傾斜状に形成されているため破砕された壁体の粉砕粉や破砕屑は山形刃17の傾斜面に沿って刃外部に排出されるので刃内部に残留されず円滑な破砕作業が遂行でき、壁破砕機Ａの押圧破砕機能を低下させることなく破砕作業を継続することができる。
【００２９】
【発明の効果】
本発明によれば、受刃を左右に配した左右受板刃で構成すると共に、裁断刃を左右に配した左右裁断板刃で構成し、同左右裁断板刃の中央空間部に山形刃を介設することにしたので、壁体を破砕する際に、左受板刃と左裁断板刃、及び右受板刃と右裁断板刃による鋏機能によって壁体を切削することができると共に、山形刃の上下面は傾斜状に形成されているため左右裁断板刃間に残留した壁体部分を先端の尖った山形刃の押圧破砕機能で圧潰することができ、さらには破砕された壁体の粉砕粉や破砕屑は山形刃の傾斜面に沿って刃外部に排出されるので刃内部に残留されず円滑な破砕作業が遂行でき、壁破砕機Ａの押圧破砕機能を低下させることなく破砕作業を継続することができる効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a wall crusher.
[0002]
[Prior art]
Conventionally, a wall crusher that uses hydraulic pressure, pneumatic pressure, etc. to move the cutting blade back and forth and cut and crush the wall held between the cutting blade and the receiving blade has a receiving blade at one end of the frame extending in the horizontal direction. In addition to being fixedly disposed, a cutting blade is disposed on the other end side so as to be able to advance and retreat, and the cutting blade is advanced in the direction of the receiving blade to cut and crush the wall between the two blades.
[0003]
Such a wall crusher advances the cutting blade in the receiving blade direction to narrow the wall body. At this time, downward stress acts on the cutting blade, and as a reaction force, the receiving blade and the cutting blade are used. The frame in a state of being bridged between the two becomes warped, so that an excessive load is applied to the frame, and the pressing stress of the cutting blade against the receiving blade is reduced, so that sufficient pressure is applied to the wall body. There was a drawback that could not be applied.
[0004]
Therefore, as disclosed in Japanese Utility Model Publication No. 2-332758, a frame is constituted by two left and right plate-like bodies arranged side by side at a distance, and both plate-like bodies of the frame are formed on the upper surface of the cutting blade. A guide rod that is inserted between them is erected, and a roller that is slidable along the frame is pivotally supported on the upper end of the guide rod so that the frame is sandwiched between the cutting blade and the roller from above and below. There has been proposed a wall crusher that can prevent the frame from warping due to downward stress on the frame (see Patent Document 1).
[0005]
In particular, in the wall crusher disclosed in Japanese Utility Model Publication No. 2-332758, the cutting blade tip is composed of left and right plate blades, and the concentrated stress of the cutting blade is increased to concentrate the pressing force on the wall body. Thus, the wall body is crushed and cut by sliding with the left and right plate blades of the receiving blade.
[0006]
[Patent Document 1]
Japanese Utility Model Publication No. 2-332758 [0007]
[Problems to be solved by the invention]
However, in the above-mentioned wall crusher, although the frame is prevented from warping by the structure in which the frame is sandwiched between the cutting blade and the roller provided continuously through the guide rod, the left and right plate blades at the cutting blade tip bite into the wall body. When the wall body is crushed and cut, the crushed wall composition is filled between the left and right plate blades at the tip of the cutting blade, the concentrated stress of the cutting blade is reduced, and no pressing force is concentrated on the wall body. As a result, the cutting blade is less likely to bite into the wall body and the crushing efficiency is reduced.
[0008]
[Means for Solving the Problems]
Therefore, the present invention comprises a guide frame composed of two left and right plate-like bodies arranged side by side at intervals, a receiving blade is provided at one end of the guide frame, a cylinder is provided at the other end, and a cylinder rod A cutting blade that performs a cutting function while sliding the inner surface of the receiving blade at the tip of the cutting blade is provided so as to be able to advance and retreat, and on the upper surface of the cutting blade, a guide rod that is inserted between both plate-like bodies of the guide frame is erected, In the wall crusher formed by pivotally supporting a roller slidable along the guide frame at the upper end of the guide rod, the receiving blade is composed of left and right receiving plate blades arranged on the left and right, and the cutting blade is It is composed of left and right cutting plate blades arranged on the left and right sides, and a tip that protrudes toward the receiving blade is positioned behind the tip edge of the left and right cutting plate blades in the central space of the left and right cutting plate blades, and the tip Side-view wedge with top and bottom surfaces inclined at a constant slope toward Interposed a and chevron blades, there is provided St. walls crusher, characterized in that the angle between the inner surface of the inclined upper and lower surfaces and the left and right cutting plate edge of the chevron blades and perpendicular .
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The present invention is a wall crusher that narrows a wall body between a receiving blade and a cutting blade that can be advanced and retracted toward the receiving blade, and cuts and crushes the wall body by the scissors function and the press crushing function of both blades. . Therefore, in this wall crusher, a guide frame is constituted by two plate-like bodies arranged side by side at a distance, a receiving blade is provided at one end of the guide frame, and a cylinder is provided at the other end. A cutting blade is provided at the tip of the cylinder rod of the cylinder, and the cutting blade is pushed out toward the receiving blade by the cylinder so that the cutting blade slides along the inner surface of the receiving blade. Therefore, at the time of crushing the wall body, the two blades perform the aforementioned claw function and the pressure crushing function, and the wall body between the two blades is cut and crushed to crush the wall body.
[0010]
In addition, a guide rod that passes between both plate-like bodies of the guide frame is provided on the upper surface of the cutting blade, and a roller that is slidable along the guide frame is provided at the upper end of the guide rod. Therefore, when the cutting blade advances and retreats by the cylinder, the roller slides on the guide frame in conjunction with the movement of the cutting blade.
[0011]
For this reason, the guide frame is always sandwiched from above and below by the cutting blades and rollers continuously provided above and below via the guide rods, and the guide frame is subjected to stress in the upward bending direction due to the forward movement of the cutting blade. Even if the frame is likely to warp in the direction opposite to the cylinder rod, the warp can be corrected by narrowing the guide frame from above and below with the cutting blade and the roller.
[0012]
Furthermore, in the present embodiment, in the wall crusher as described above, the left and right receiving plate blades are arranged with the receiving blades on the left and right, and the left and right cutting plate blades are arranged with the cutting blades on the left and right. A wedge-shaped chevron blade having a tip projecting toward the receiving blade is interposed in the central space of the cutting plate blade.
[0013]
Therefore, when crushing the wall body, the wall body is cut by the scissors function by sliding between the left and right receiving plate blades and the left and right cutting plate blades, as well as the biting into the wall body by the cutting blade. When the cutting blade is pressed against the wall body, the wall portion remaining between the left and right cutting plate blades is crushed by the pressing crushing function of the angled blade with a sharp tip, and thus cut, crushed and crushed. The wall composition is discharged to the outside of the blade along the upper and lower inclined surfaces of the chevron blade, and does not accumulate in the left and right receiving plate blades and the left and right cutting plate blades, and can efficiently and quickly crush the wall body. .
[0014]
【Example】
Hereinafter, an embodiment of a wall crusher according to the present invention will be described with reference to the drawings.
[0015]
FIG. 1 is a perspective view of an embodiment of a wall crusher according to the present invention. As shown in the figure, a wall crusher A in this embodiment includes a receiving blade 1 and a cutting blade for cutting and crushing a wall body. 2, a cylinder 3 that advances and retracts the cutting blade 2 toward the receiving blade 1, and a guide frame 4 that supports the receiving blade 1, the cutting blade 2, and the cylinder 3.
[0016]
The guide frame 4 has a structure in which two left and right plate-like bodies 5 and 5 extending in the front-rear direction are arranged side by side in an upright state with a gap therebetween, and the receiving blade 1 is vertically suspended at the lower end portion, while the lower rear end portion The cylinder 3 is vertically suspended.
[0017]
In particular, the cylinder 3 has a front end portion of a cylinder body 6 extending in the front-rear direction attached to the lower end of the rear end of the guide frame 4 so that the cylinder rod 7 moves forward and backward under the guide frame 4. By connecting the cutting blade 2 to the tip of the rod 7, the cutting blade 2 can be freely advanced and retracted toward the receiving blade 1 suspended from the lower end of the guide frame 4.
[0018]
Moreover, on the upper surface of the cutting blade 2, a guide rod 8 is erected between the two plate-like bodies 5, 5 of the guide frame 4, and the guide frame 4 is provided at the upper end of the guide rod 8. A roller 9 is slidably supported along the upper surface. Therefore, the cylinder 3 is connected to the guide frame 4, the cutting blade 2 is connected to the cylinder 3, the guide rod 8 is connected to the cutting blade 2, and the roller 9 is connected to the guide rod 8. In addition, the rollers 9 are connected to each other and the guide frame 4 is sandwiched from both sides in cooperation with the cutting blade 2. For this reason, even when the wall body is crushed, a downward narrow pressure stress acts on the cylinder rod 7 that supports the cutting blade 2, and the guide frame 4 that receives the reaction force is likely to warp upward. The guide frame 4 can be pressed downward by the rollers 9 that contact the upper surface of the guide frame 4 so that the guide frame 4 does not warp upward. In the figure, 10 is a gripping rod, 11 is a pivot of the roller 9, and 12 is a reinforcing rib for reinforcing the connection between the cylinder 3 and the guide frame 4.
[0019]
In the wall crusher A configured as described above, a feature of the present invention is the shape of the cutting blade 2 that is paired with the receiving blade 1 and sandwiches the wall body and cuts and crushes the wall body. Therefore, the configuration of the receiving blade 1 and the cutting blade 2 will be described below.
[0020]
FIG. 2 is a schematic diagram showing the configuration of the receiving blade 1 and the cutting blade 2 of the wall crusher A according to the present invention. As shown in the drawing, the receiving blade 1 is a left and right receiving plate blade formed in a substantially rectangular plate shape. 13 and 13 are juxtaposed in a standing state, and the upper ends of the left and right receiving plate blades 13 and 13 are connected by an upper connecting body 14 that is also formed in a substantially rectangular plate shape to form a substantially portal shape in front view. ing.
[0021]
On the other hand, the cutting blade 2 has the left and right cutting plate blades 15 and 15 formed in a substantially rectangular plate shape arranged side by side in an upright state, and the rear end between the left and right cutting plate blades 15 and 15 is also formed in a substantially rectangular plate shape. They are connected by the formed rear connecting body 16 to form a substantially portal shape in plan view. When the cylinder 3 is pushed in the direction of the receiving blade 1, the outer surfaces of the left and right cutting plate blades 15 and 15 slide along the inner surfaces of the left and right receiving plate blades 13 and 13. 1 is inserted between the left and right receiving plate blades 13,13.
[0022]
In addition, in the central space S formed between the left and right cutting plate blades 15 and 15, a wedge-shaped blade 17 having a wedge shape in a side view with a tip projecting toward the receiving blade 1 is interposed. The upper and lower surfaces are formed in an inclined shape with a constant gradient toward the tip. In particular, the tip of the mountain-shaped blade 17 is formed so as to be located behind the tip edges of the left and right cutting plate blades 15 and 15. In this way, since the tip of the angle blade 17 is positioned behind the tips of the left and right cutting plate blades 15 and 15, when crushing the wall, the left and right cutting plate blades 15 are ahead of the angle blade 17. 15 and 15 are in contact with the wall body, and the upper and lower surfaces of the angled blade 17 are formed in an inclined shape, so the crushed powder and crushed debris from the crushed wall body along the inclined surface of the angled blade 17 Since it is discharged to the inside, there is an effect that smooth crushing work can be performed without remaining inside the blade.
[0023]
In addition, the angle blade 17 is formed separately from the left and right cutting plate blades 15 and 15 and the rear connecting body 16, and is then inserted and fixed between the left and right cutting plate blades 15 and 15. When fixing 17, a connecting tool mounting recess 18 that is recessed toward the rear connector 16 is formed in the middle of the up-and-down inclined surface of the angle blade 17, and screws, bolts, and the like are formed in the connecting tool mounting recess 18. A connector 19 is inserted and fixed to the rear connector 16.
[0024]
Accordingly, the connector 19 is housed in the connector mounting recess 18 and does not protrude from the vertically inclined surface of the angle blade 17. Therefore, at the time of crushing the wall body, it is possible to prevent the connecting tool 19 from directly colliding with the wall body and being damaged, and to prevent the mounting of the angle blade 17 from being loosened due to the damage of the connecting tool 19. it can.
[0025]
The receiving blade 1 and the cutting blade 2 have the above-described configuration, and when the wall body is crushed by the main wall crusher A using the receiving blade 1 and the cutting blade 2, the receiving blade 1 and the cutting blade 2 are interposed between the receiving blade 1 and the cutting blade 2. The sandwiched wall first comes into contact with the front end surfaces of the left and right cutting plate blades 15 and 15 as the cutting blade 2 advances in the direction of the receiving blade 1, and the left receiving plate blade 13 and the left cutting plate blade 15. The abutment surface is cut by the scissors function of the right receiving plate blade 13 and the right cutting plate blade 15. The wall portion remaining between the left and right cutting plate blades 15 and 15 without being cut next reaches the angled blade 17 having a sharp tip interposed between the left and right cutting plate blades 15 and 15. Then, it is crushed by the press crushing function of the mountain-shaped blade 17. At this time, the wall to be crushed by the chevron blade 17 is easily cut out by the left and right cutting plate blades 15 and 15 in advance at a predetermined interval, that is, the interval between the left cutting plate blade 15 and the right cutting plate blade 15. Can be crushed.
[0026]
Thus, in this wall crusher A, since a wall body is crushed using the scissors function and press crushing function of the receiving blade 1 and the cutting blade 2, a wall body can be crushed effectively. In addition, since the left and right cutting plate blades 15 and 15 protrude forward from the angle blade 17 interposed between the left and right cutting plate blades 15 and 15, when crushing the wall body, the tip of the angle blade 17 The left and right cutting plate blades 15 and 15 come into contact with the wall body, cut out the wall body at a predetermined interval, and the angled blade 17 with a sharp tip crushes the wall body cut out at a predetermined interval and easily crushed. As a result, the efficiency of crushing can be improved, and the burden on the angled blade 17 that is pointed and easily worn can be reduced.
[0027]
Furthermore, the angle blade 17 is formed in a wedge shape when viewed from the side as described above. Compared with the case where the angle blade 17 is formed in a wedge shape when viewed from above, the angle between the left and right cutting plate blades 15 and 15 (the upper and lower slopes of the angle blade 17) Since the angle formed by the inner surfaces of the left and right cutting plate blades 15 and 15 is substantially a right angle, the crushed wall body is unlikely to be clogged between the angle blade 17 and the left and right cutting plate blades 15 and 15.
[0028]
In addition, since the upper and lower surfaces of the angled blade 17 are formed in an inclined shape, the crushed powder and crushed debris from the crushed wall body are discharged to the outside of the blade along the angled surface of the angled blade 17 and remain inside the blade. Therefore, the smooth crushing operation can be performed, and the crushing operation can be continued without reducing the press crushing function of the wall crusher A.

【The invention's effect】
According to the present invention, the receiving blade is composed of left and right receiving plate blades arranged on the left and right, and the cutting blade is composed of left and right cutting plate blades arranged on the left and right, and the chevron blade is formed in the central space portion of the left and right cutting plate blades. Since it was decided to intervene, when crushing the wall body, the wall body can be cut by the scissors function by the left receiving plate blade and the left cutting plate blade, and the right receiving plate blade and the right cutting plate blade, Since the upper and lower surfaces of the angle blade are formed in an inclined shape, the wall portion remaining between the left and right cutting plate blades can be crushed by the pressure crushing function of the angled blade with a sharp tip, and further the crushed wall body The crushed powder and crushed debris are discharged to the outside of the blade along the inclined surface of the angled blade, so that it can be smoothly crushed without remaining inside the blade, and crushed without deteriorating the pressure crushing function of the wall crusher A There is an effect that the work can be continued.
