Description

Highly efficient wood crusher

본 발명은 고성능 목재 파쇄기에 관한 것으로 보다 상세하게는 파쇄실에 투입되는 목재를 파쇄드럼의 회전커터가 회전하면서 목재표면을 찍어서 할퀴듯이 파쇄하여 파쇄효과를 극대화시키고 파쇄드럼에서 발생하는 풍력을 이용하여 파쇄작용을 보조하고 목재투입과 파쇄실의 배출에 이용할 수 있게 구성하여 능율적으로 톱밥을 생산할 수 있게한 것이다.The present invention relates to a high-performance wood shredder, and more particularly, the wood that is put into the shredding chamber is shredded by rotating the rotating cutter of the shredding drum to scratch the surface of the wood to maximize the shredding effect and using wind power generated from the shredding drum. It assists in the shredding operation and can be used for the input of wood and the discharge of the shredding chamber, so that the sawdust can be produced efficiently.

종래의 목재 파쇄기는 투입되는 목재를 자르거나 강제로 부수는 파쇄날을 장치하여 파쇄하도록 한 것이므로 파쇄능율이 떨어지고 이로인해 톱밥생산이 저조한 문제점이 있었다Conventional wood shredders are designed to be shredded by cutting or forcibly crushing the input wood, so the shredding capacity is lowered, resulting in poor sawdust production.

본 발명은 상기와 같은 종래의 문제점을 해소하고자 개발된 것으로, 첨부된 도면에 의거 보다 상세하게 설명하면 다음과 같다The present invention was developed to solve the conventional problems as described above, will be described in more detail based on the accompanying drawings as follows.

파쇄기 본체(1) 상부에 목재가 투입되는 투입호퍼(11)가 설치되고 내부에 파쇄실(2)이 구비되어 파쇄칼이 장치되며 하부로 배출실이 형성되는 공지의 파쇄기에있어서, 파쇄기 본체 내측에 설치되는 파쇄실(2)의 내면에 다수의 파쇄돌기(21)와 바람막이(22)를 설치하고, 톱밥이 배출되는 배출부에 타공망(2a)을 볼트(2a')로 착탈가능케 설치하며, 파쇄실(2) 중심부에는 구동축(30) 외주에 다수의 지지판(31)을 부착하여 지지판 사이에 회전커터(4)를 힌지결합한 파쇄드럼(3)을 장치하여, 파쇄드럼(3)의 지지판(31) 사이에 설치되는 회전커터(4)의 끝을 회전방향으로 절곡시켜 그 내측에 파쇄날(41)을 볼트(401)로 착탈가능케 장치하고 각 회전커터(4)는 등간격으로 배치하며, 그 사이에 간격유지구(33)를 끼워서 되는 구성이다.In a known crusher in which a hopper 11 into which wood is introduced is placed on top of the crusher main body 1 and a crushing chamber 2 is provided therein, a crushing knife is installed, and a discharge chamber is formed at the bottom of the crusher body. A plurality of crushing protrusions 21 and windshields 22 are installed on the inner surface of the crushing chamber 2 to be installed in the crushing chamber 2, and the perforated network 2a is detachably installed with a bolt 2a 'at the discharge portion where the sawdust is discharged. In the center of the crushing chamber 2, a plurality of support plates 31 are attached to the outer periphery of the drive shaft 30, and a crushing drum 3 hinged to the rotary cutter 4 is provided between the support plates, thereby supporting the support plate of the crushing drum 3 ( 31 is bent in the direction of rotation of the end of the rotary cutter (4) installed between the crushing blade 41 to be detachable with a bolt 401 on the inside, and each rotary cutter (4) is arranged at equal intervals, It is the structure by which the space | interval holding part 33 is interposed.

이와 같이 구성된 본 발명은 파쇄실 내측의 파쇄드럼이 빠른 속도로 회전하면 원심력에 의하여 회전커터가 원주방향으로 방사상이 되게 펼쳐져서 회전하면서 목재를 파쇄시키게되는데, 각 회전커터는 그 끝이 회전방향으로 절곡되어 그 끝에 파쇄날(41)이 부착되어 있으므로 투입되는 목재를 찍어 할퀴는 방식으로 파쇄하기 때문에 파쇄효과를 극대화시켜 실수없는 파쇄가 이루어진다.In the present invention configured as described above, when the crushing drum inside the crushing chamber rotates at a high speed, the rotating cutter is radially expanded in the circumferential direction by the centrifugal force to crush the wood while rotating, and each rotary cutter has its end in the rotational direction. Since the shredding blade 41 is bent at the end thereof is bent and crushed in a way to take the input wood, the shredding is maximized so that the shredding effect is maximized.

따라서 파쇄량을 배가시키게 되는 효과가 있고 파쇄드럼이 회전하면서 바람이 발생하면 파쇄실 내면에 부착된 바람막이에 의하여 부딪쳐서 파쇄실 내부로 유도되므로 파쇄된 칩을 윤동시키면서 내면에 부착된 파쇄돌기(21)와 회전카터(10)와의 충돌을 유도하여 파쇄실내에서 2차적인 파쇄가 이루어지게되어 파쇄물을 미세하게 파쇄할 수 있으며 동시에 유도된 바람은 배출구쪽으로 작용하므로 투입구로 투입되는 목재의 원활한 투입을 유도하게 된다.Therefore, there is an effect of doubling the amount of shredding and when the wind is generated while the shredding drum rotates, it is hit by the windshield attached to the shredding chamber and guided into the shredding chamber. And secondary collision in the crushing chamber by inducing a collision with the rotating cart 10 can be finely crushed crushed matter and at the same time the induced wind acts toward the discharge port to induce the smooth input of the wood introduced into the inlet do.

따라서 보다 원활하게 목재투입과 파쇄가 이루어져 능율적인 생산을 달성하는 효과를 얻는 것이다.Therefore, the input and crushing of the wood more smoothly is to achieve the effect of achieving efficient production.
