Description
본 고안은 콘크리트 혼합기에 관한 것으로, 더욱 상세하게는 혼합기 내부의 교반회전축을 일정각도로 이격형성된 나선형의 교반날개로 형성하므로서, 혼합시간을 단축하면서도 그 혼합률이 향상되게 한 콘크리트 혼합기용 교반회전축에 관한 것이다.The present invention relates to a concrete mixer, and more specifically, to a stirring mixer shaft for concrete mixer, which is formed by forming a spiral stirring blade spaced at a predetermined distance from the inside of the mixer, thereby improving the mixing rate while reducing the mixing time. It is about.
콘크리트 혼합물은 각종 건물 및 교량등과 같이 인공구조물에 널리 사용되는 것으로서, 기계적인 강도가 좋고 성형이 용이한 혼합재료이다.Concrete mixture is widely used in artificial structures such as various buildings and bridges, and is a mixed material having good mechanical strength and easy molding.
이러한 콘크리트 혼합물에는 시멘트 및 모래, 골재 등이 일정비율로 혼합되는 것이며, 그 혼합량에 따라 기계적인 강도 및 양생시간이 결정되기도 한다.In the concrete mixture, cement, sand, aggregate, etc. are mixed at a predetermined ratio, and the mechanical strength and curing time may be determined according to the mixing amount.
또한, 콘크리트 혼합물을 사용하기 위해서는 콘크리트 혼합공장(콘크리트 믹서) 및 콘크리트에 의한 2차 제품 생산업체(벽돌 등)에서는 전기한 혼합물을 투입하고 이를 고루 혼합하기 위한 혼합기를 필요로 한다.In addition, in order to use a concrete mixture, a concrete mixing plant (concrete mixer) and a secondary product producer by brick (brick, etc.) require a mixer for inputting and mixing the mixture.
이러한 혼합기는 함체의 내부에 모터의 구동에 의해 회전하는 교반축이 설치되어 있으며, 전기한 교반축은 도 4의 도시와 같이 각봉(100)의 외주면에 90°의 간격을 갖고 이격되게 삽입형성된 다수의 교반날개(101)(101')로 구성되어지며, 이러한 교반축을 평행되게 두개를 형성하므로 각 교반축의 교차회전에 의해 콘크리트 혼합물이 고루 섞이게 하는 것이다.Such a mixer is provided with a stirring shaft that is rotated by the driving of the motor in the interior of the housing, the agitated shaft as shown in FIG. It is composed of agitating blades 101 and 101 ', so that two of these stirring shafts are formed in parallel so that the concrete mixture is evenly mixed by the cross rotation of each stirring shaft.
그러나, 전기한 바와 같은 통상의 콘크리트 혼합기용 교반회전축은 도 4의 도시와 같이 단순히 이격되고 사방으로 형성되어 있는 단순한 구조이므로, 함체 내부에 투입된 혼합물을 고루 섞이게 하기 위해서는 많은 시간과 동력을 필요로 한다.However, since the stirring shaft for a conventional concrete mixer as described above is a simple structure that is simply spaced apart and formed in all directions as shown in FIG. 4, it requires a lot of time and power to uniformly mix the mixture introduced into the enclosure. .
즉, 각각의 교반날개의 회전에 의해 혼합물이 와류되거나 위치가 바뀌며 혼합되는 것이 아니라 교반날개가 회전하는 부근에서만 지속적으로 혼합되는 문제점이 있으므로, 그 혼합률이 불규칙하며 완전한 혼합상태를 갖기 위해서는 많은 혼합시간 및 전기적인 에너지를 필요로 하므로 매우 비경제적인 문제점이 있는 것이다.That is, there is a problem that the mixture is continuously vortexed or changed in position by the rotation of each stirring blade, but is continuously mixed only in the vicinity of the rotation of the stirring blade, so that the mixing ratio is irregular and a lot of mixing is necessary to have a complete mixing state. There is a very uneconomical problem because it requires time and electrical energy.
본 고안은 전기한 바와 같은 문제점을 제거코저 안출한 것으로서, 원통체의 회전축에 다수의 교반날개를 삽입 설치하되, 각각의 교반날개를 45°의 간격으로 이격되면서도 회전되게 삽입설치하고, 각각의 교반날개는 그 형성방향을 전후 교반날개의 대각선 방향으로 향하게 설치하므로서, 다수의 교반날개에 의해 나선형의 교반축이 형성되게 하여, 그 교반회전축에 의해 후측의 혼합물이 전방으로 이동하고 전방의 혼합물이 후측으로 이동함과 동시에, 각각의 교반날개에 의해 혼합되어지므로 횡방향 및 종방향의 혼합이 동시에 이루어져 그 혼합시간이 매우 단축됨은 물론 혼합률이 매우 향상되는 효과가 있는 콘크리트 혼합기용 교반회전축을 제공함에 본 고안의 목적이 있는 것이다.The present invention is designed to remove the problems as described above, inserting a plurality of stirring blades to the rotating shaft of the cylindrical body, each stirring blade is installed to rotate while being spaced at intervals of 45 °, each stirring The blades are formed so that the formation direction is directed in the diagonal direction of the front and rear stirring blades, so that a spiral stirring shaft is formed by a plurality of stirring blades, and the rear mixture moves forward and the front mixture is moved forward by the stirring rotation shaft. As it moves to the side and is mixed by each stirring blade, the mixing in the transverse direction and the longitudinal direction is performed at the same time, which shortens the mixing time and provides a stirring rotating shaft for the concrete mixer which has the effect of greatly improving the mixing rate. There is a purpose of the present invention.

봉체의 외주면에 날개축에 의해 결합된 다수의 교반날개를 형성한 통상의 콘크리트 혼합기용 교반회전축에 있어서,In the stirring rotary shaft for a conventional concrete mixer, in which a plurality of stirring blades are joined to the outer circumferential surface of the rod by a blade shaft,
원통형의 봉체(1) 외주면에 45°각도로 이격되며 나선상으로 회전삽입되는 다수의 교반날개(2)(2')를 날개축(3)(3')에 의해 결합형성하고,A plurality of stirring blades 2, 2 ', which are spaced at a 45 ° angle to the outer circumferential surface of the cylindrical rod body 1, and are inserted in a spiral manner, are coupled to each other by the wing shafts 3, 3',
각각의 교반날개(2)(2')는 그 형성방향을 전후의 날개축(3)(3')이 삽입된 대각선방향으로 형성하므로, 다수의 교반날개(2)(2')가 봉체(1)의 외주면에 나선상으로 형성되게 하되,Since each stirring blade (2) (2 ') forms the formation direction in the diagonal direction in which the front and rear wing shafts (3) and (3') were inserted, many stirring blades (2) and (2 ') have a rod ( On the outer circumferential surface of 1) to form a spiral
각 교반날개(2)(2')의 상단부는 나선상의 곡률과 일치되는 곡선부(4)를 형성하고, 하단부의 일측에는 모따기부(5)를 형성하여 되는 것이다.The upper end of each stirring blade (2) (2 ') is to form a curved portion 4 to match the curvature of the spiral, and to form a chamfer (5) on one side of the lower end.
도면중 미설명 부호 10은 구동모터, 11은 함체다.In the figure, reference numeral 10 denotes a drive motor, and 11 denotes a housing.
이상과 같은 본 고안의 작용을 첨부도면에 의해 보다 상세히 설명하면 다음과 같다.Referring to the operation of the present invention as described above in more detail by the accompanying drawings as follows.
도 2는 본 고안 교반회전축이 장착된 상태의 콘크리트 혼합기를 측면도시한 설명도로서, 콘크리트 혼합기의 함체(11)내에 평행축설된 교반회전축이 서로 교차되게 장착되어 있는 것이다.Figure 2 is an explanatory view showing a concrete mixer in a state in which the stirring rotary shaft of the present invention is mounted, parallel stirring shafts arranged in parallel in the housing 11 of the concrete mixer.
이러한 교반회전축은 봉체(1)의 외주면에 다수의 날개축(3)(3') 선단에 교반날개(2)(2')가 부착되어 있음을 알 수 있다.It can be seen that the stirring blades are attached to the stirring blades 2, 2 'at the tip of the plurality of blade shafts 3, 3' on the outer circumferential surface of the rod 1.
이렇게 장착 고정된 교반회전축은 도 3의 도시와 같이 함체(11)의 내부로 각종 혼합물 즉, 시멘트 및 모래, 골재등이 투입되면 함체(11) 일측의 구동모터(10)가 회전하여 그 연결수단에 의해 교반회전축의 봉체(1)를 회전시키게 되고, 봉체(1)의 회전과 동시에 다수의 교반날개(2)(2')가 함께 회전하며 내부의 혼합물이 고루 섞이게 하는 것이다.As shown in FIG. 3, when the fixed stirring shaft is mounted, various mixtures, that is, cement, sand, aggregate, etc. are introduced into the enclosure 11, and the driving motor 10 on one side of the enclosure 11 rotates to connect the connecting means. By rotating the rod body (1) of the stirring rotary shaft, a plurality of stirring blades (2) (2 ') rotates together with the rotation of the rod body (1) to mix the mixture inside.
즉, 각각의 교반날개(2)(2')에 의해 도면상 수직방향의 혼합작용이 이루어짐은 물론, 나선상의 교반날개(2)(2') 장착구조에 의해 후측의 혼합물이 전방으로 이동하며 혼합되므로 수평방향의 혼합 또한 동시에 이루지는 것이다.That is, the mixing action of the vertical direction in the drawing is made by each stirring blade (2) (2 '), as well as the rear mixture is moved forward by the spiral stirring blade (2) (2') mounting structure Because of the mixing, horizontal mixing also takes place at the same time.
따라서, 종래와 같이 일방향 즉, 수직방향의 혼합에 의해 콘크리트 혼합물을 생산하였던 것에 비해 수직방향 및 수평방향의 혼합이 동시에 이루어지므로 그 혼합시간이 현저히 단축됨은 물론 혼합 품질도 보다 향상되는 것이다.Therefore, since the mixing in the vertical direction and the horizontal direction is simultaneously performed as compared with the concrete mixture produced by mixing in one direction, that is, the vertical direction as in the prior art, the mixing time is significantly shortened and the mixing quality is further improved.
또한, 교반날개(2)(2')의 선단부에 형성된 곡선부(4)는 각각의 곡선부가 봉체(1)에 나선상으로 삽입되는 경우 그 곡선부(4)에 의해 나선상의 연속된 원형구조를 갖게 하므로 그 봉체(1) 및 교반날개(2)(2')의 회전이 보다 용이하게 한 것이며, 교반날개(2)(2')의 하측 일부를 경사상으로 절단하여 모따기부(5)를 형성하므로 교반되는 혼합물의 진행방향에 따라 그 모따기부(5)로 혼합물이 용이하게 빠져나가도록 한 것으로서, 혼합 효율이 증가함은 물론 회전되는 교반날개(2)(2')의 회전부하를 감소시키는 작용을 하는 것이다.Further, the curved portion 4 formed at the tip of the stirring blades 2, 2 'has a continuous circular structure spirally formed by the curved portion 4 when each curved portion is inserted into the rod 1 in a spiral manner. Since the rod body 1 and the stirring blades 2 and 2 'are more easily rotated, a portion of the lower side of the stirring blades 2 and 2' is cut in an oblique shape and the chamfer 5 is cut. As it forms, the mixture is easily escaped to the chamfer 5 according to the advancing direction of the mixture to be stirred, thereby increasing the mixing efficiency and reducing the rotating load of the rotating stirring blades 2 and 2 '. It is to act.
이상과 같이 통상의 콘크리트 혼합기에 있어서, 그 함체 내부의 교반회전축을 나선상의 교반날개로 다수 구성하므로 그 나선상의 교반날개에 의해 혼크리트의 혼합시간이 단축됨은 물론 혼합효율이 향상되는 것이다.As described above, in the conventional concrete mixer, since the stirring rotary shaft inside the enclosure is composed of a plurality of spiral stirring blades, the mixing time of the horn concrete is shortened and the mixing efficiency is improved by the spiral stirring blades.
이상과 같은 작용에 의한 본 고안 콘크리트 혼합기용 교반회전축은 다수의 교반날개에 의해 나선형의 교반축이 형성되게 하여, 그 교반회전축에 의해 후측의 혼합물이 전방으로 이동하고 전방의 혼합물이 후측으로 이동함과 동시에, 각각의 교반날개에 의해 혼합되어지므로 횡방향 및 종방향의 혼합이 동시에 이루어져 그 혼합시간이 매우 단축됨은 물론 혼합률이 매우 향상되는 효과가 있는 것이다.The stirring shaft for the present invention concrete mixer by the action as described above is to form a spiral stirring shaft by a plurality of stirring blades, the rear mixture is moved to the front and the front mixture is moved to the rear by the stirring shaft. At the same time, since the mixing blades are mixed by each stirring blade, the mixing in the transverse direction and the longitudinal direction is performed at the same time, and the mixing time is very shortened, and the mixing rate is greatly improved.
