본 발명은 발효교반차의 에스컬레이터용 드럼 회전축과 베어링 결합구조에 관한 것으로서 더욱 상세히는 회전축과 베어링의 결합을 별도의 결합구를 사용하여 결합하므로서 숙련공이 아닌 초보 작업자도 힘들이지 않고 빠른시간내에 결합작업을 마칠수 있으므로 숙련공을 활용하지 않음에 따른 인건비를 절감할 수 있는 것은 물론 발효교반차 시스템 전체를 설치하기 위한 시간을 그만큼 단축할 수 있는 발효교반차의 에스컬레이터용 드럼 회전축과 베어링 결합구조에 관한 것이다.The present invention relates to a drum rotating shaft and bearing coupling structure for the fermentation stirrer, more specifically, by combining the coupling of the rotary shaft and the bearing using a separate coupling port, even a novice skilled worker can effortlessly combine in a short time It is possible to reduce the labor cost of not using skilled workers, as well as to the rotating shaft and bearing coupling structure for the escalator of the fermentation stirrer that can shorten the time to install the entire fermentation stirrer system.

일반적으로 축분이나 음식물쓰레기 등의 수분이 많은 유기성폐기물은 수분조절제와 혼합하여 발효조에 저장시킨 다음 이를 인공적으로 호기성 발효를 시키고, 그 발효열로 건조시켜서 안전한 퇴비가 되도록 하고 있다.Generally, organic wastes with a lot of moisture, such as animal waste or food waste, are mixed with a moisture control agent and stored in a fermenter, then artificially aerobic fermentation, and dried with the heat of fermentation to ensure safe composting.

그러나 교반시키지 않고 자연적으로 발효시키는 것은 주로 혐기성 발효로서 각종 부패 세균 등이 번식하여 악취가 심하며, 이러한 상태로 퇴비화하여 사용하면 농작물이 병들고 잡초가 무성하게 되는 결점이 있다.However, the fermentation naturally without stirring is mainly anaerobic fermentation, and various decaying bacteria, etc., propagate and have a bad smell. When composted and used in this state, crops become ill and weeds become lush.

그리고 이와는 다르게 온풍에 의해 강제 건조시키는 것 역시 악취가 심하고 온풍발생에 따른 유지비가 많이 소모되며, 농지에 투입하였을 때 그때 농지에서 발효되면서 발생되는 고온의 발효열로 식물들이 죽게되는 심각한 문제점 있다.And unlike the forced drying by the warm air is also a bad smell and a lot of maintenance costs due to the warm air is generated, there is a serious problem that the plants die due to the high temperature fermentation heat generated by fermentation in farmland when it is put into the farmland.

따라서 상기의 문제점을 해결하기 위하여 유기성폐기물과 톱밥이나 왕겨등의 수분조절제를 혼합한 다음 발효조에 투입하고, 교반시켜서 호기성 발효가 촉진되게 하는 발효교반차가 개발되어 사용되고 있다.Therefore, in order to solve the above problems, a fermentation stirrer is developed and used to mix organic waste with moisture control agents such as sawdust or rice husk, and then put into a fermenter and agitate to promote aerobic fermentation.

즉, 일반적인 발효교반차는 도 1 에서 도시한 바와같이 일단이 벽체로 막힌 발효조(10)의 양측벽 상면의 레일에서 가로이송대가 전/후 방향으로 이동되게 하고, 상기 가로이송대의 전/후 프레임상에는 또 세로방향의 레일을 설치한후 에스컬레이터(20)가 힌지축을 기점으로 실린더(30)에 의해 각도가 조절되는 세로이송대를 좌/우방향으로 이동 가능하게 설치한 것이다. That is, the general fermentation stirrer is as shown in Figure 1 so that the transverse carriage in the front / rear direction on the rail of the upper side wall of the fermentation tank 10, one end of which is blocked by the wall, on the front / rear frame of the transverse carriage In addition, after installing the rail in the vertical direction, the escalator 20 is installed so as to move in the left / right direction, the longitudinal carriage that the angle is adjusted by the cylinder 30 from the hinge axis.

그리고 상기 에스컬레이터(20)의 외측둘레에는 체인(21)이 설치되어 구동모터(40)에 의해 체인(21)이 에스컬레이터(20)의 외측둘레를 따라 회전되도록 구성되어 있으며, 상기 체인(21)에는 일정한 간격으로 다수개의 교반삽날(22)이 설치되어 있다. In addition, a chain 21 is installed at an outer circumference of the escalator 20 so that the chain 21 is rotated along the outer circumference of the escalator 20 by the driving motor 40. A plurality of stirring blades 22 are provided at regular intervals.

따라서 에스컬레이터(20)의 체인(21)이 회전되면 상기 체인(21)에 설치된 다수개의 교반삽날(22)에 의해 발효조(10)의 퇴비가 퍼올려진후 그 뒤쪽으로 넘어가게 되면서 교반작업이 수행되는 것이다.Accordingly, when the chain 21 of the escalator 20 is rotated, the compost of the fermentation tank 10 is spun up by the plurality of stirring blades 22 installed on the chain 21 and then moved to the rear thereof. will be.

한편 상기 에스컬레이터(20)의 구동을 위한 드럼(도면중 미도시)의 회전축(51)은 도 2에서와 같이 원활한 회전을 위하여 베어링(60)과 결합하여 사용하는 것이나 종래의 결합구조는 많은 문제점이 있는 것으로서 이를 상세히 설명하면 다음과 같다.Meanwhile, the rotating shaft 51 of the drum (not shown in the drawing) for driving the escalator 20 is used in combination with the bearing 60 for smooth rotation as shown in FIG. 2, but the conventional coupling structure has many problems. If this is described in detail as follows.

즉, 상기 회전축(51)을 베어링(60)과 결합하기 위해서는 회전축(51)의 일단 을 베어링(60)의 내륜(61)속으로 끼워야 하는데 이때 회전축(51)은 내륜(61)속에 타이트하게 끼워져 회전축(51)의 외주면이 내륜(61)의 내주면에 밀착된 상태를 유지하여야 만이 회전축(51)이 회전시 내륜(61)도 함께 회전되면서 회전축(51)이 보다 더 원활하게 회전되는 것이다.That is, in order to couple the rotary shaft 51 with the bearing 60, one end of the rotary shaft 51 should be inserted into the inner ring 61 of the bearing 60. At this time, the rotary shaft 51 is tightly inserted into the inner ring 61. Only when the outer circumferential surface of the rotating shaft 51 is in close contact with the inner circumferential surface of the inner ring 61, the rotating shaft 51 rotates more smoothly while the inner shaft 61 is also rotated when the rotating shaft 51 rotates.

따라서 회전축(51)이 내륜(61)과 타이트한 상태를 유지하기 위해서는 회전축(51)의 구경을 내륜(61)의 내경 크기와 거의 같도록 형성하여야 하나 이는 회전축(51)을 내륜(61)에 끼우기가 상당히 까다롭고 힘이들어 많은 작업시간이 소요되는 것이어서 이로인해 발효 교반차 전체 시스템 설치작업이 그만큼 지연되어 이를 조금이라도 개선하고자 숙련된 작업자를 활용하므로 이로인한 인건비의 상승이 커지게 되는 문제점이 있다.Therefore, in order to maintain the state in which the rotating shaft 51 is tight with the inner ring 61, the diameter of the rotating shaft 51 should be formed to be almost the same as the inner diameter of the inner ring 61. However, the rotating shaft 51 is inserted into the inner ring 61. This is a very demanding and laborious process that takes a lot of time, and thus, the entire system of fermentation agitation tea installation is delayed by that, and a skilled worker is used to improve it. .

또한 이와는 다르게 회전축(51)의 구경을 내륜(61)의 내경 크기보다 약간 작게하여 회전축(51)을 내륜(61)속에 보다 손쉽게 끼울수도 있으나 이는 회전축(51)과 내륜(61)사이에 미세한 틈새가 발생되어 회전축(51)이 혼자서 헛돌게 되는 문제점이 있다.Alternatively, the diameter of the rotating shaft 51 may be slightly smaller than the inner diameter of the inner ring 61 so that the rotating shaft 51 may be more easily inserted into the inner ring 61, but this is a fine gap between the rotating shaft 51 and the inner ring 61. There is a problem that the rotary shaft 51 is lost by itself.

따라서 본 발명은 상기의 문제점을 해결하기 위한 것으로서 본 발명의 목적은 드럼의 회전축을 베어링과의 결합시 숙련공이 아닌 초보 작업자들도 힘들이지 않고, 짧은시간에 결합작업을 마칠수 있어 숙련공을 활용하지 않음에 따라 숙련공에 들어가는 인건비를 절감할 수 있으면서도 발효 교반차 시스템 전체의 설치시간 을 그만큼 단축시킬 수 있는 발효교반차의 에스컬레이터용 드럼 회전축과 베어링 결합구조를 제공하기 위한 것이다.Therefore, the present invention is to solve the above problems, the object of the present invention is to combine the rotating shaft of the drum with the bearing, even for beginners who are not skilled workers, it is easy to finish the coupling work in a short time does not utilize skilled workers In accordance with the present invention, the labor cost for skilled workers can be reduced, while the fermentation stirrer can provide a rotating shaft and bearing coupling structure for the escalator that can reduce the installation time of the whole fermentation agitation vehicle.

이와같은 본 발명의 목적은 몸체의 길이방향을 따라 형성된 절결부에 의해 구경이 신축 조절되고, 나선결합부가 구비된 외주면 선단에서 후단으로 갈수록 구경이 점차 커져서 내부로 드럼의 회전축이 쉽게 끼워지는 깔대기형의 결합구와; 상기 베어링의 내륜 외부로 돌출되는 결합구의 선단 외주면에 끼워지며, 주연에 다수의 텐션용 돌기가 돌출된 이붙이와셔와; 상기 베어링의 내륜 외부로 돌출되는 결합구의 선단 나선결합부에 나사 결합되어 결합구의 구경을 압축하는 너트로 이루어지므로서 달성되는 것이다.The purpose of the present invention is a funnel type that the diameter is stretched and adjusted by the cutout formed along the longitudinal direction of the body, the diameter is gradually increased toward the rear end from the outer circumference of the outer peripheral surface provided with a spiral coupling portion easily inserted into the rotating shaft of the drum inside With a splice of; A tooth washer fitted to an outer circumferential surface of the distal end of the coupling that protrudes outside the inner ring of the bearing and having a plurality of tension protrusions protruding from the periphery thereof; It is achieved by being screwed to the distal end of the coupling portion of the coupling portion protruding to the outside of the inner ring of the bearing to compress the diameter of the coupling sphere.

이러한 본 발명은 베어링에 쉽게 끼워지는 깔때기형으로 된 별도의 결합구를 구비하여 베어링에 결합구를 끼운후 그 결합구속에 회전축을 끼운 상태에서 너트를 체결하므로서 회전축과 베어링의 결합작업을 초보작업자도 힘들이지 않고, 쉽게할 수 있으므로서 상기의 목적을 효과적으로 달성할 수 있다.The present invention has a separate funnel of funnel type to be easily fitted to the bearing and then inserts the coupling sphere into the bearing and then tightens the nut in a state in which the rotation shaft is inserted into the coupling sphere. It is possible to achieve the above object effectively without effort and ease.

이하 본 발명의 특징을 효과적으로 달성할 수 있는 바람직한 실시 예로서 그 기술구성 및 작용효과를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3 은 본 발명에 따른 드럼의 회전축과 베어링의 결합구조를 예시한 요부분리사시도이고, 도 4a,4b,4c는 본 발명에 따라 회전축과 베어링의 결합되는 과정을 순차적으로 보인 요부 도면으로서 도4a는 너트를 체결한후 조여주기전의 상태이 고, 도4b는 너트를 완전히 조여준 상태를 나타낸 것이며, 도 4c는 조여진 너트에 형성된 걸림홈에 와셔의 돌기를 절곡시켜 끼워준 상태를 예시한 도면이다.Figure 3 is a partial perspective view illustrating a coupling structure of the rotating shaft and the bearing of the drum according to the present invention, Figures 4a, 4b, 4c is a main view showing a sequence of the coupling process of the rotating shaft and the bearing in accordance with the present invention Figure 4a Figure 4b is a state before tightening the nut after tightening, Figure 4b shows a state that the nut is fully tightened, Figure 4c is a view illustrating a state of bending the projection of the washer in the locking groove formed in the tightened nut.

이와같은 본 발명은 발효교반차의 에스컬레이터 구동을 위한 드럼(500)의 회전축(510)과 베어링(600)을 서로 결합함에 있어서, 몸체의 길이방향을 따라 형성된 절결부(710)에 의해 구경이 신축 조절되고, 나선결합부(720)가 구비된 외주면 선단에서 후단으로 갈수록 구경이 점차 커져서 내부로 드럼(500)의 회전축(510)이 쉽게 끼워지는 깔대기형의 결합구(700)와 상기 베어링(600)의 내륜 외부로 돌출되는 결합구(700)의 선단 외주면에 끼워지며, 주연에 다수의 텐션용 돌기(810)가 돌출된 이붙이와셔(800)와 상기 베어링(600)의 내륜 외부로 돌출되는 결합구(700)의 선단 나선결합부(720)에 나사 결합되어 결합구(700)의 구경을 압축하는 너트(900)로 이루어진 것을 특징으로 하는 것으로서 도면중 미설명 부호 (100)은 베어링을 보호하기 위한 커버이다.In the present invention as described above, in coupling the rotating shaft 510 and the bearing 600 of the drum 500 for driving the escalator of fermentation stirrer, the diameter is stretched by the notch 710 formed along the longitudinal direction of the body Adjusted, funnel-shaped coupling sphere 700 and the bearing 600 is easy to fit the rotary shaft 510 of the drum 500 into the caliber gradually increases from the outer circumferential end of the spiral coupling portion 720 is provided toward the rear end Fits to the outer circumferential surface of the distal end of the coupler 700 protruding outside the inner ring of the inner ring, and a toothed washer 800 and a plurality of tension protrusions 810 protruding from the inner ring of the inner ring of the bearing 600 The screw 100 is screwed to the distal end portion coupling portion 720 of the coupler 700 to compress the aperture of the coupler 700, and the reference numeral 100 in the drawing protects the bearing. It is a cover for doing so.

이러한 본 발명은 발효교반차의 에스컬레이터(도면중 미도시)의 구동을 위한 드럼(500)의 회전축(510)을 베어링(600)과 결합하여 상기 회전축(510)이 원활하게 회전될 수 있도록 한 것은 일반적인 기술구성이나 본 발명에서의 특징은 회전축(510)과 베어링(600)의 결합작업을 숙련공이 아닌 초보 작업자라도 힘들이지 않고 빠른시간에 결합할 수 있도록 하여 숙련공을 활용하지 않음에 따른 인건비를 절감할 수 있는 것은 물론 발효교반차 시스템 전체를 설치하기 위한 시간을 그만큼 단축할 수 있는 것이다.The present invention is to combine the rotating shaft 510 of the drum 500 for driving the escalator (not shown in the figure) of the fermentation stirrer with the bearing 600 so that the rotating shaft 510 can be smoothly rotated The general technical configuration or features of the present invention can be combined with the rotating shaft 510 and the bearing 600, even a novice worker can be combined quickly and effortlessly to reduce labor costs by not using skilled workers. Of course, the time required to install the whole fermentation stirrer system can be shortened by that much.

즉, 본 발명은 도 3 에서 예시한 바와같이 회전축(510)을 베어링(600)에 직 접 결합하는 것이 아니고, 별도의 결합구(700)를 베어링(600)의 내륜(610)속에 끼워 선단을 돌출시킨 상태에서 회전축(510)을 다시 결합구(700)내로 끼워준후 상기 결합구(700)선단에 이붙이와셔(800)를 끼워주고 다시 너트(900)를 체결한 것으로 이는 회전축(510)과 베어링(600)의 결합을 간편하게 할수 있는 것이다.That is, the present invention does not directly connect the rotating shaft 510 to the bearing 600, as illustrated in FIG. 3, and inserts a separate coupling hole 700 into the inner ring 610 of the bearing 600. In the protruding state, the rotary shaft 510 is inserted into the coupling sphere 700 again, and then the attachment washer 800 is fitted to the tip of the coupling sphere 700 and the nut 900 is fastened again. It is possible to simplify the coupling of the bearing 600.

이와같은 본 발명은 도 4a에서와 같이 우선 베어링(600)의 내륜(610)속으로 선단에 나선결합부(720)가 형성된 결합구(700)를 끼워 선단이 내륜(610)밖으로 돌출되도록 하는데 상기 결합구(700)는 선단에서 후단으로 갈수록 구경이 커지는 깔대기형으로 제작되어 있으므로 상기 결합구(700)를 내륜(610)속으로 끼우면 구경이 작은 선단은 내륜(610)속으로 별 무리없이 끼워지고, 선단보다 구경이 큰 후단은 내륜(610)에 타이트하게 밀착되어 잘 들어가지 않는 것으로 이때에는 결합구(700)의 후미를 강하게 밀어넣거나 약간의 타격을 가하면 결합구(700)의 선단이 이미 베어링(600)의 내륜(610)속에 끼워져 있는 상태이므로 결합구(700)는 내륜(610)속으로 쉽게 끼워지면서 즉, 결합구(700)의 후미는 내륜(610)의 내주면과 타이트하게 밀착되고, 선단은 내륜(610)의 내주면과 약간 이격된 상태로 돌출된다.As described above, the present invention inserts the coupling hole 700 having the spiral coupling portion 720 formed at the tip into the inner ring 610 of the bearing 600 so that the tip protrudes out of the inner ring 610. Since the coupler 700 is manufactured in a funnel type which increases in diameter from the front end to the rear end, when the coupler 700 is inserted into the inner ring 610, the tip having a small diameter is inserted into the inner ring 610 without any difficulty. , The rear end having a larger diameter than the front end is tightly adhered to the inner ring 610 so that it does not enter well. At this time, if the rear end of the coupler 700 is strongly pushed or a slight blow is applied, the tip of the coupler 700 is already bearing. Since the coupling hole 700 is easily inserted into the inner ring 610 because the state is fitted into the inner ring 610 of the 600, that is, the rear end of the coupling hole 700 is tightly attached to the inner circumferential surface of the inner ring 610. The tip is slightly different from the inner circumferential surface of the inner ring 610. It protrudes in an isolated state.

이후 드럼(500)의 회전축(510)을 상기 베어링(600)의 내륜(610)속에 끼워진 결합구(700)속으로 끼우는데 상기 결합구(700)는 위에서 상술한 바와같이 깔대기 형상으로 되어 있어 회전축(510)을 결합구(700)에 끼워주는데에는 별 무리가 없다.Thereafter, the rotary shaft 510 of the drum 500 is inserted into the coupling hole 700 inserted into the inner ring 610 of the bearing 600. The coupling hole 700 has a funnel shape as described above. There is no particular force in fitting 510 to the coupler 700.

여기서 상기 베어링(600)과 결합구(700)를 먼저 결합한후 그 결합구(700)에 회전축(510)을 끼우지 않고, 상기 회전축(510)을 결합구(700)에 끼워준후 다시 그 결합구(700)를 베어링(600)의 내륜(610)속으로 끼워주어도 무방하다.Here, the bearing 600 and the coupler 700 are first coupled, and then the rotary shaft 510 is inserted into the coupler 700 without the rotary shaft 510 inserted into the coupler 700, and then the coupler ( 700 may be inserted into the inner ring 610 of the bearing 600.

이처럼 회전축(510)을 베어링(600)에 결합된 결합구(700)속으로 끼워 나선결합부(720)가 형성된 선단만이 베어링(600)밖으로 돌출시킨후 상기 결합구(700)의 선단에 이붙이와셔(800)를 끼워주고, 그 위로 너트(900)를 체결한다.As such, only the tip end of the spiral coupling part 720 inserted into the coupling hole 700 coupled to the bearing 600 protrudes out of the bearing 600, and then at the end of the coupling hole 700. Insert the washer 800, and tighten the nut 900 thereon.

이후 도4b에서와 같이 너트(900)를 조여주면 결합구(700)의 구경은 점차 압축되는데 이는 상기 결합구(700)의 몸체에는 길이방향으로 절결부(710)가 형성되어 있으므로 너트(900)를 조이면 상기 결합구(700)는 절결부(710)에 의해 구경이 압축되어 결합구(700)속에 위치한 회전축(510)을 압박하여 주는 것인데 이는 너트(900)를 조이면 조일수록 결합구(700)가 회전축(510)을 더욱 압박하게 되어 처음 회전축(510)을 결합구(700)속에 끼울때에는 헐겁게 끼워지더라도 너트(900)를 조여줌에 따라 결합구(700)가 회전축(510)을 강하게 압박하여 회전축(510)이 결합구(700)내에서 유동되거나 헛돌 우려가 전혀없다.Then, as shown in FIG. 4B, when the nut 900 is tightened, the diameter of the coupler 700 is gradually compressed. This is because the cutout portion 710 is formed in the body of the coupler 700 in the longitudinal direction. When tightening the coupler 700 is compressed by the cutout 710 to press the rotating shaft 510 located in the coupler 700, which is tightened by tightening the nut 900, the coupler 700 Presses the rotating shaft 510 further, and when the first rotating shaft 510 is inserted into the coupling hole 700, the coupling hole 700 presses the rotating shaft 510 strongly as the tightening nut 900 is tightened even if it is loosely fitted. Therefore, there is no fear that the rotating shaft 510 may flow in the coupling hole 700 or be used.

이때 상기 결합구(700)는 너트(900)가 조여지는 선단의 구경만이 압축되고, 후단은 압축되지 않고 베어링(600)의 내륜(610)내주면에 타이트하게 밀착된 상태를 유지하는 것이므로 장기간이 지나더라도 결합구(700)가 베어링(600)에서 이탈될 우려가 없다.At this time, the coupling hole 700 is compressed only the diameter of the front end to which the nut 900 is tightened, the rear end is not compressed and maintains a tight contact with the inner circumferential surface of the inner ring 610 of the bearing 600 for a long time Even if there is no fear that the coupler 700 is separated from the bearing 600.

또한 본 발명은 상기 너트(900)의 외주연에는 상기 이붙이와셔(800)의 돌기(810) 중 일부가 절곡되어 끼워지는 걸림홈(910)을 다수 형성하여 너트(900)의 풀림이 방지되게 한 것으로 도4c에서와 같이 너트(900)를 완전히 조여준후 이붙이와셔(800)에 형성된 다수의 돌기(810)중 너트(900)에 형성된 걸림홈(910)과 대향되는 위치에 있는 돌기(810)를 절곡시켜서 걸림홈(910)에 각각 끼워지도록 하면 너트 (900)는 이붙이와셔(800)에 의해 1차적으로 견고한 체결상태를 유지한 상태에서 2차적으로 더욱 체결상태가 견고하여 장기간에 걸쳐 진동이 전달되더라도 너트(900)가 풀어질 우려가 없다.In addition, the present invention is formed on the outer periphery of the nut (900) by forming a plurality of engaging grooves (910) in which some of the protrusions 810 of the toothed washer 800 is bent and fitted to prevent loosening of the nut (900). As shown in FIG. 4C, after the nut 900 is completely tightened, the protrusion 810 in a position opposite to the locking groove 910 formed in the nut 900 among the plurality of protrusions 810 formed in the attaching washer 800. ) And the nut (900) to be fitted into the locking groove (910), respectively, by the toothed washer (800) to maintain a first tightly tightened state, the second state is more tightly tightened over a long period of time Even if vibration is transmitted, the nut 900 may not be released.
