본 고안은 상기와 같은 사정을 고려하여 이루어진 것으로, 본 고안의 목적은 건축공사 또는 토목공사 현장에서 시멘트, 물, 골재(모래, 자갈 등을 말함) 등을 일정비율로 혼합하여 콘크리트를 생산하는 믹서의 혼합날개의 표면(골재에 의하여 마모가 발생하는 부분)에 폐 텅스텐 합금강 분쇄입자를 용접 육성하여 혼합날개의 마모를 지연시킴으로써 마모에 따른 혼합날개의 교체시기를 연장할 수 있는 새로운 형태의 폐 텅스텐 합금강 분쇄입자가 표면에 육성된 콘크리트 믹서용 혼합날개를 제공하는데 있다.The object of the present invention is to provide a mixer for producing concrete by mixing cement, water, and aggregate (referred to as sand, gravel, etc.) at a certain ratio in a construction work or a civil engineering work site. , A new type of pulverized tungsten that can extend the period of replacement of the blades due to wear by welding and pulverizing pulverized tungsten alloy steel particles on the surface of the mixed blades of the blades (where abrasion occurs by aggregate) There is provided a blending blade for a concrete mixer in which an alloy steel crushed particle is grown on a surface.

상기한 본 고안의 목적은, 상부 양측이 전방과 후방측으로 뒤틀린 형태를 갖으며 중앙부분에 믹서(1)의 샤프트(2)와 연결을 위한 복수 개의 관통공(11)과 일면에 차후 폐 텅스텐 합금강 분쇄입자가 육성되는 복수 개의 육성홈(12)과 가장자리로 육성부(13)가 일체로 형성된 몸체(10);와,The above object of the present invention is to provide a mixer having a plurality of through holes 11 for connecting the shaft 2 of the mixer 1 to a central portion thereof and a plurality of through holes 11 for connecting the pulverized tungsten alloy steel (10) in which a plurality of growing grooves (12) in which pulverized particles are grown and a breeding part (13)

상기 몸체(10)의 육성홈(12)과 육성부(13) 및 일측 측면(14)에 CO2 분위기에서 연철와이어로 아크웰딩하여 육성되는 폐 텅스텐 합금강 분쇄입자(20);를 포함하는 것을 특징으로 하는 폐 텅스텐 합금강 분쇄입자가 표면에 육성된 콘크리트 믹서용 혼합날개에 의해 달성될 수 있다.And pulverized tungsten alloy steel ground particles 20 grown by arc welding with a wrought iron wire in a CO2 atmosphere to the growing groove 12, the growing portion 13 and the side surface 14 of the body 10 The pulverized tungsten alloy steel pulverized particles can be accomplished by mixing blades for a concrete mixer which are grown on the surface.

상기 폐 텅스텐 합금강 분쇄입자(20)는 폐기되는 텅스텐 합금강의 각종공구를 텅스텐카바이드 분말로 육성경화시킨 회전 햄머와 맞물림 고압로울러로 5~10메쉬 범위의 입도와 20~40메쉬 범위의 입도를 갖도록 분쇄한 분쇄입자임을 특징으로 한다.The pulverized tungsten alloy steel pulverized particles 20 are pulverized to have a particle size in the range of 5 to 10 mesh and a particle size in the range of 20 to 40 mesh by a high pressure roller which is meshed with a rotary hammer in which various tools of tungsten alloy steel to be discarded are grown and hardened with tungsten carbide powder. And is a pulverized particle.

이상과 같이 본 고안에 따른 폐 텅스텐 합금강 분쇄입자가 표면에 육성된 콘크리트 믹서용 혼합날개는 시멘트, 물, 골재 등의 원료를 일정비율로 혼합하여 콘크리트를 생산하는 믹서의 내부 샤프트에 착탈 가능하게 조립되는 구성으로 골재와 잦은 충돌이 발생하는 혼합날개의 표면의 여러 부분에 폐 텅스텐 합금강 분쇄입자를 용접 육성함으로써 혼합날개의 마모를 지연시켜 사용기한을 기존 콘크리트 믹서의 4배이상으로 교체시기를 연장할 수 있는 효과를 통하여 종래 단기간에 교체해야 하는 불편함을 해소하여 작업성을 향상시키고 혼합날개의 구입비용을 절감할 수 있는 효과가 있다.As described above, the mixing blades for the concrete mixer in which the pulverized particles of the pulverized tungsten alloy steel according to the present invention are fired on the surface are assembled by detachably attaching to the inner shaft of the mixer producing the concrete by mixing the raw materials such as cement, water, This is because the pulverized particles of pulverized tungsten alloy steel are welded to various parts of the surface of mixed blades where frequent collisions with aggregates occur, thereby delaying the blending of the blades and extending the replacement period to more than four times that of conventional concrete mixers It is possible to improve the workability and reduce the purchase cost of the mixing blades.

즉, 본 고안에 따른 폐 텅스텐 합금강 분쇄입자가 표면에 육성된 콘크리트 믹서용 혼합날개는 몸체의 콘크리트와 충돌하는 측면 전체에 폐 텅스텐 합금강 분쇄입자층을 형성하여 1차적으로 콘크리트와의 충돌에 따른 혼합날개의 마모를 방지하고 2차적으로 몸체 일면에 형성한 폐 텅스텐 합금강 분쇄입자층을 통하여 콘크리트가 혼합하는 과정에서 몸체 일면에 미끄러져 이동하는 과정에서 발생하는 혼합날개의 마모를 방지하는 효과가 있다.That is, the mixed blades for the concrete mixer in which the pulverized particles of the pulverized tungsten alloy steel according to the present invention are fired on the surface, form a pulverized particle layer of the pulverized tungsten alloy steel on the entire side where the concrete of the body collides with the concrete, And the wear of the mixing blades generated during the process of sliding the slurry on one side of the body during the mixing of the concrete through the pulverized tungsten alloy steel pulverized particle layer formed on one side of the body is prevented.

또한, 혼합날개의 몸체에 육성홈을 형성하고 그 내부에 폐 텅스텐 합금강 분쇄입자층을 육성함으로써 몸체로부터 폐 텅스텐 합금강 분쇄입자층이 돌출되는 것을 최소화하여 폐 텅스텐 합금강 분쇄입자층의 돌출에 따른 콘크리트가 혼합되는 과정에서 몸체와 폐 텅스텐 합금강 분쇄입자층 사이에 잔존물이 발생하는 것을 방지할 수 있도록 하여 믹서의 사용 후 물청소를 통하여 쉽게 혼합날개를 청결하게 유지할 수 있는 효과가 있다.In addition, it is possible to minimize the protrusion of the pulverized tungsten alloy steel particles from the body by forming the grooved grooves in the body of the mixed blades and cultivating the pulverized particles of pulverized tungsten alloy steel in the body, thereby minimizing the protrusion of the pulverized tungsten alloy steel It is possible to prevent the residues from being generated between the body and the pulverized particle layer of the pulverized tungsten alloy steel, so that the mixing blades can be easily cleaned by cleaning the water after use of the mixer.
