본 고안은 경운기의 동력을 이용하여 목분용소재를 분쇄하는 목분제조기의 컷터에 관한 것으로, 특히 소재를 효과적으로 분쇄시킴은 물론 컷팅날의 마모, 절단시에 교체가 용이하도록 한 것이다.The present invention relates to a cutter of a wood powder mill that grinds wood powder using the power of a cultivator. In particular, it effectively grinds the material and makes it easy to replace the cutting blade when worn and cut.

경운기용 목분제조기(A)는 제1도에서와 같이, 공급되는 소재를 강제이송시키도록 프레임(1)에 설치한 상하트랙구동체(2, 2')와, 상하트랙조립체(2, 2')에 구동력을 전달하는 전동부(3)와, 강제이송된 소재를 소정규격으로 분쇄시키는 컷팅부(4)와, 컷팅부(4)의 하단에 구비되어 목분을 수거하는 수거부(5)와, 수거부(5)에 집결된 목분을 프레임(1) 외부로 강제토출시키는 토출부(6)로 구성되며, 상기 전동부(3)와 컷팅부(4) 및 토출부(6)는 경운기의 구동력을 제공받아 소정방향으로 구동하게 된다.As shown in FIG. 1, the wood cultivator A for cultivators includes upper and lower track actuators 2 and 2 'installed on the frame 1 to force the material to be supplied, and upper and lower track assemblies 2 and 2'. Transmission unit for transmitting the driving force to the), a cutting unit 4 for crushing the forced conveyed material to a predetermined standard, and a collecting unit 5 for collecting wood powder provided at the lower end of the cutting unit 4 and And a discharge part 6 for forcibly discharging the wood powder collected at the collecting part 5 to the outside of the frame 1, wherein the transmission part 3, the cutting part 4, and the discharge part 6 are formed of a cultivator. The driving force is supplied to drive in a predetermined direction.

여기에서, 컷팅부(4)는 프레임(1)의 고정구(11)에 회전축(41)을 설치하고, 회전축(41)내에는 다수의 간격유지구(42)와 회전컷팅날(43)을 교호로 밀집설치한 구성으로 이루어져 있다.Here, the cutting part 4 is provided with a rotating shaft 41 in the fixing member 11 of the frame 1, and alternately between the plurality of interval holding holes 42 and the rotary cutting blade 43 in the rotating shaft 41. Consists of a dense installation.

도면중 미설명부호(44)는 카바, (31)은 감속기, (V)는 벨트이다.In the figure, reference numeral 44 is a cover, 31 is a speed reducer, and V is a belt.

그런데, 이러한 구성의 목분제조기(A)는 컷팅부(4)의 회전컷팅날(43)이 마모 또는 절단되어 교체해야할 경우, 회전축(41) 전체를 분해한후 간격유지구(42)와 회전컷팅날(43)을 전부분해해야 하므로 보수에 많은 시간을 필요로 하고, 회전컷팅날(43) 사이에 목분등이 삽입, 누적될경우 분쇄효율이 저하되며, 회전컷팅날(43)의 중량이 가벼워 분쇄 진행중 소재와의 마찰로 인해 회전력, 즉 분쇄력이 극도로 저하되는 등의 여러가지 문제점이 유발된다.By the way, when the wood cutting machine (A) of this configuration is to be replaced by cutting or cutting the rotary cutting blade 43 of the cutting portion 4, after disassembling the entire rotary shaft 41, the interval holding slot 42 and the rotary cutting Since the blade 43 needs to be completely disassembled, a lot of time is required for repair, and when the wood powder is inserted and accumulated between the rotary cutting blades 43, the grinding efficiency is lowered, and the weight of the rotary cutting blades 43 is lighter. The friction with the material during the grinding process causes a variety of problems such as extremely low rotational force, that is, the grinding force.

본 고안은 상기한 문제점들을 감안하여 컷팅날의 유지, 보수가 극히 용이하면서도 최대의 분쇄효과를 얻을수 있게된 경운기용 목분제조기의 컷터를 제공하기 위한 목적으로 안출된 것인바, 이하에서 상기 목적을 달성하는 본 고안의 바람직한 실시예를 상세히 설명한다.The present invention has been devised for the purpose of providing a cutter of a cultivator for wood cultivator that can achieve the maximum grinding effect while maintaining and repairing the cutting blade in view of the above problems. It will be described in detail a preferred embodiment of the present invention.

제2도는 본 고안 컷터(7)의 설치상태를 부분 정단면도로서 나타낸 것으로, 프레임(2)의 고정구(11)에는 회전측(41)이 베어링(B)으로 구름설치되고, 회전축(41)의 고정구(11)내측에는 한쌍의 회전판(71)이 대향설치되어 키이 등으로 고정된다.2 is a partial front sectional view showing the installation state of the cutter 7 of the present invention. The rotating side 41 is rolled onto the bearing B in the fixture 11 of the frame 2, Inside the fastener 11, a pair of rotating plates 71 are opposed to each other and fixed with a key or the like.

회전판(71)에는 회전축(41)을 중심으로하여 방사상의 안내 구멍(72)이 등간격으로 다수개소 형성되어 웨이트바(73)가 안내 구멍(72)을 따라 이동가능하게 설치되며, 웨이트바(WEIGHT BAR : 73)는 회전축(41) 방향의 인장력을 갖도록 탄성부재(74)로 탄력 설치된다.A plurality of radial guide holes 72 are formed in the rotating plate 71 at regular intervals around the rotating shaft 41 so that the weight bar 73 is movable along the guide hole 72. WEIGHT BAR: 73 is elastically installed to the elastic member 74 to have a tensile force in the direction of the rotation axis 41.

또한 회전판(71)의 외측에는 다수의 삽입장홈(75)이 원주상 등간격으로 형성되고 그 내측에는 안착홈(76)이 함몰형성되어 컷팅날 조립체(8)가 안착고정된다.In addition, the outer side of the rotating plate 71 is formed with a plurality of insertion grooves 75 are formed at equal intervals in the circumference and the mounting groove 76 is recessed in the inner side is fixed to the cutting blade assembly (8).

제3도 내지 제5도에서는 컷팅날조립체(8)의 구성 및 그 조립상태를 각각 나타낸 것으로, 볼트헤드(81)를 형성한 조립축(82)의 타단에 너트(83)가 체결되는 나사부(84)를 소정구간 형성시키고, 이 조립축(82)에는 스페이서(SPACER : 85)와 컷팅날(86)이 밀집되도록 교호로 삽입된다.3 to 5 show the structure of the cutting blade assembly 8 and its assembled state, respectively, and includes a screw part in which the nut 83 is fastened to the other end of the assembly shaft 82 on which the bolt head 81 is formed. 84 is formed in a predetermined section, and the assembly shaft 82 is alternately inserted so that spacers 85 and the cutting blade 86 are densely packed.

이 컷팅날 조립체(8)는 조립축(82)이 상기 삽입장홈(75)을 통해 삽입된 상태에서 나사부(84)에 체결된 너트(83)를 조여줌으로써 너트(83)와 볼트헤드(81)가 안착홈(86)에 삽입된 상태로 조립을 완료하게 된다.The cutting blade assembly 8 is a nut 83 and the bolt head 81 by tightening the nut 83 fastened to the threaded portion 84 in the state that the assembly shaft 82 is inserted through the insertion slot groove 75. The assembly is completed in the state inserted into the seating groove (86).

회전판(71)에 설치된 컷팅날 조립체(8)의 사이에는 컷팅날(86)의 회동범위를 제한하는 제한축(77)이 고정설치되는데, 이 제한축(77)은 컷팅날(86)의 위치제한 및 소재분쇄시에 목분이 회전판(71)내로 삽입되는 것을 방지하는 기능도 갖게 된다.Between the cutting blade assembly 8 installed on the rotating plate 71 is fixed to the limiting shaft 77 limiting the range of rotation of the cutting blade 86, the limiting shaft 77 is the position of the cutting blade 86 It also has a function of preventing the wood powder from being inserted into the rotating plate 71 at the time of restriction and material grinding.

도면 중 미설명부호(41')는 경운기와 벨트(V)로 연결되어 동력을 전달받는 풀리이다.In the drawing, reference numeral 41 ′ is a pulley connected to the tiller and the belt V to receive power.

이와같은 구성의 본 고안 컷터(7)는 회전축(41)이 회전하며 회전판(71)을 회전시키게 되는데, 회전초기에 회전판(71)에 구비된 웨이트바(73)는 회전축(41)과 근접된 상태에 있게 되며, 회전이 진행될수록 그 원심력에 의해 웨이트바(73)는 탄성부재(74)의 인장력을 극복하며 안내구멍(72)을 따라 외측으로 이동하게 된다.The present invention cutter 7 of such a configuration is to rotate the rotating shaft 41 and the rotating plate 71, the weight bar 73 provided in the rotating plate 71 at the beginning of the rotation is in close proximity to the rotating shaft 41 As the rotation progresses, the weight bar 73 overcomes the tensile force of the elastic member 74 by the centrifugal force and moves outward along the guide hole 72.

이러한 상태에서의 회전판(71)은 웨이트바(73)의 중량에 의해 회전력이 증가되어 높은 소재분쇄 효율을 나타냄은 물론 회전안정성을 부여하게 된다.Rotating plate 71 in this state is increased the rotational force by the weight of the weight bar 73, showing a high material grinding efficiency, as well as providing rotational stability.

한편, 회전판(71)의 외측둘레에 조립된 컷팅날 조립체(8)는 고속회전시에도 분리가 방지되는데, 이는즉, 조립축(82)을 삽입지지하는 삽입장홈(75)의 내측에 안착홈(76)이 함몰형성되어, 조립축(82) 양단의 볼트헤드(81)와 너트(83)가 함몰된 상태로 안착됨에 기인하여 안정된 조립상태를 유지하게 된다.On the other hand, the cutting blade assembly (8) assembled on the outer circumference of the rotating plate 71 is prevented from being separated even at high speed, that is, the mounting groove on the inner side of the insertion cabinet groove 75 for supporting the assembly shaft 82 is inserted. 76 is recessed to maintain a stable assembled state due to the bolt head 81 and the nut 83 on both ends of the assembly shaft 82 being recessed.

그러나, 사용중 조립축(82)에 끼워진 컷팅날(86)의 부분적인 마모, 파손 발생시에는 조립축(82)의 나사부(84)에 체결된 너트(83)를 약간풀어서 볼트헤드(81)와 너트(83)가 안착홈(76)외부에 위치되도록하면, 조립축(82)은 삽입장홈(75)을 통해 쉽게 분리되므로 유지, 보수는 극히 용이하며 그 작업은 단시간내에 완료된다.However, in the case of partial wear or breakage of the cutting blade 86 fitted to the assembly shaft 82 during use, the bolt head 81 and the nut are loosened slightly by loosening the nut 83 fastened to the threaded portion 84 of the assembly shaft 82. When the 83 is positioned outside the seating groove 76, the assembly shaft 82 is easily separated through the insertion slot groove 75, so maintenance and repair are extremely easy and the work is completed in a short time.

또한, 회전판(71)의 회전에 의해 컷팅날조립체(8)가 목분 소재용 목재를 분쇄할때에, 컷팅날(86)은 소재와의 마찰에 의해 역방향으로 밀리게 되는데, 컷팅날 조립체(8)의 사이에 구비된 제한축(77)은 컷팅날(86)과 스페이서(85)의 유동을 제한하여 컷팅날(86)의 기능상실은 방지되며, 이러한 상태에서는 소재가 회전축(41) 방향으로의 침투를 방지하게 되어 이물침투에 의한 웨이트바(73) 및 회전축(41)의 작동불량요인도 적극적으로 해소시키게 되는 등의 여러가지 잇점이 있다.In addition, when the cutting blade assembly 8 pulverizes the wood for wood flour material by the rotation of the rotary plate 71, the cutting blade 86 is pushed in the opposite direction by friction with the material, and the cutting blade assembly 8 Restriction shaft 77 provided between the (1) restricts the flow of the cutting blade 86 and the spacer 85 to prevent the malfunction of the cutting blade 86, in this state the material in the direction of the rotation axis 41 It is possible to prevent the infiltration of the weight bar 73 and the operation of the malfunction caused by the foreign material penetrating the aggressive axis also has a number of advantages, such as to actively eliminate.
