It relates to a blade for cutting, in particular, the cemented carbide particles (tungsten alloy) consisting of small particles of 10 to 30 mesh (masch) at the end of the blade is fused to increase the grinding efficiency by the grinding blade, and the wear phenomenon of the blade due to grinding The present invention relates to a blade for grain grinding and a method for producing the same, which are capable of inhibiting the extension of the service life as much as possible, and at the same time, the rapid grinding of the grain to be crushed and the grinding of a large amount of grain in a short time.

일반적으로, 분쇄기라 함은 전동장치에 의해 분쇄용 칼날 등을 회전시켜, 칼날에 의해 공급된 물질, 즉, 옥수수, 보리, 밀 이나 콩 등과 같은 곡물을 타격 및 가압하여 작은 입자를 갖도록 분쇄하는 장치이다.In general, a pulverizer is a device that rotates a grinding blade or the like by a power transmission device, and pulverizes the material supplied by the blade, that is, grains such as corn, barley, wheat or soybeans, to be crushed to have small particles. to be.

본 고안에서 적용하고자 하는 분쇄기는 주로, 곡물을 분쇄시켜 가축용 사료의 원료로 사용하기 위한 것으로서, 현재, 사용되고 있는 분쇄기의 분쇄용 칼날은 첨부 도면 도 1에 도시된 바와 같이, 호퍼를 통해 일정량의 곡물이 공급되는 분쇄통(112)에 고정지그(110)가 내설되고, 상기 고정지그(110)에는 다단형태를 이루며 다수개의 분쇄용 칼날(100)이 결합되며, 전동장치(120)에 의해 회전되도록 이루어진 구성을 갖는다.The grinder to be applied in the present invention is mainly used to grind grain and use it as a raw material for livestock feed. Currently, the grinding blade of the grinder being used is shown in FIG. 1 through a hopper.

본 발명에 따른 분쇄용 칼날(1)은 회전되면서 곡물에 직접 접촉되는 부위에 초경부재(4)가 융착되어 있으므로, 기존의 칼날에 비해 분쇄가 이루어지는 면적이 크고, 분쇄가 이루어지는 부위에 대한 강도가 우수하며, 몸체(2)에 곡물이 직접 접촉되지 않고 초경부재(4)에서 분쇄가 이루어지므로, 칼날(1)에 의한 곡물의 분쇄 효율을 높일 수 있고, 접촉에 따른 몸체(1)의 마모현상을 최대한 억제할 수 있어 칼날의 사용수명을 연장할 수 있는 것이다.Since the cutting member 1 for crushing according to the present invention is fused with a cemented carbide member 4 at a portion which is in direct contact with the grain while being rotated, the area of crushing is larger than that of the existing blade, and the strength of the crushing portion is increased. Excellent, since the grain is not in direct contact with the body (2) is pulverized in the cemented carbide member (4), it is possible to increase the grinding efficiency of the grain by the blade (1), wear phenomenon of the body (1) by contact Can be restrained as much as possible to extend the service life of the blade.

또한, 곡물의 분쇄가 이루어지는 칼날(1) 부위, 즉, 초경부재(4)에 의해 표면이 거칠게 이루어져 있으므로, 우수한 분쇄력을 갖게 되고, 단시간에 다량의 곡물을 분쇄할 수 있으며, 일정하고 미세한 입자로 곡물을 분쇄할 수 있는 것이다.In addition, since the surface is roughened by the area of the blade 1, that is, the cemented carbide member 4, in which the grain is crushed, it has excellent grinding power, and can pulverize a large amount of grain in a short time. The grain can be crushed.

한편, 이상에서와 같이, 초경부재(4)가 융착된 분쇄용 칼날(1)을 제조하려면, 여러 단계를 거치게 되는 바, 본 발명에 따른 분쇄용 칼날(1)의 제조방법은 도 4 및 도 5에 도시된 바와 같이, 10∼30매쉬의 입자 크기를 갖는 초경부재를 구비한 상태[단계(S10)]에서, 진동발생을 위한 진동소자가 장착된 공급기에 공급[단계(S20)]한 다음, 가열토치를 이용하여 칼날을 약 1800∼2600℃로 가열[단 계(S30)]시켜 일부분이 반용융되도록 한 후, 상기 공급기에 칼날을 위치시킨 상태에서, 진동소자를 구동시켜 공급기에 진동을 발생시키게 되면, 발생된 진동에 의해 공급기에 담겨진 초경부재가 공급관을 통해 가열·반용융되어진 칼날(1)에 뿌려지듯 공급[단계(S40)]된다.On the other hand, as described above, in order to manufacture the cemented carbide blade 4 is a fusion blade (1) is subjected to a number of steps, the method of manufacturing the grinding blade 1 according to the present invention is 4 and FIG. As shown in Fig. 5, in the state of having a cemented carbide member having a particle size of 10 to 30 mesh (step S10), it is supplied to a feeder equipped with a vibration element for generating vibration [step S20]. After heating the blade to about 1800-2600 ° C. (step S30) using a heating torch, the part is semi-melted, and the vibration element is driven by driving the vibrating element while the blade is placed in the feeder. When it is generated, the cemented carbide member contained in the feeder is supplied as if sprayed onto the blade 1 heated and semi-melted through the supply pipe (step S40).

따라서, 진동에 의해 칼날의 반용융된 부위에 초경부재가 공급되어 융착되면, 가열·반용융된 칼날을 냉각[단계(S50)]시켜 분쇄용 칼날을 완성하게 되는 것이다.Therefore, when the cemented carbide member is supplied to the semi-melted portion of the blade by vibration and is fused, the heated and semi-melted blade is cooled (step S50) to complete the grinding blade.
