본 발명은 노면청소차의 블로워와 연결된 배기덕트에 적층되거나 고착된 이물질을 물 세척으로 말끔하게 제거하여 노면청소차의 흡입력 저하를 방지하는 기술에 관한 것이다.The present invention relates to a technique for preventing the deterioration of suction power of the road cleaning vehicle by removing the foreign matter laminated or stuck in the exhaust duct connected to the blower of the road cleaning vehicle by washing with water.

근자에 들어 국민 의식 수준의 향상으로 주변 환경 미화에 대한 관심이 날로 증대되고 있으며, 특히 도시 미관과 관련하여 폐기물의 처리가 중요시되고 있다.In recent years, as the level of national consciousness improves, interest in the surrounding environment is increasing day by day, and the disposal of waste is particularly important in relation to the beauty of the city.

이러한 가운데, 도로 주변에 흩어져 있는 낙엽이나 쓰레기, 모래 등과 같은 노상 쓰레기들은 도시 미관을 해칠 뿐만 아니라 하수관거로 흘러들어가거나 수질 오염을 유발하게 되므로 수시로 이를 제거할 필요가 있다.Among these, roadside wastes such as fallen leaves, garbage, and sand scattered around the road not only damage the aesthetics of the city, but also flow into sewage pipes or cause water pollution.

따라서, 각 지방자치단체는 청소장비를 탑재한 청소차량을 이용하여 노상 쓰레기를 처리하고 있는데, 대체로 종래의 노면청소차는 블로워가 작동하면서 흡입력을 발생함으로써 롤러브러시가 쓸어내는 노면의 쓰레기 및 오물 등을 적재함의 내부로 연결된 흡입관을 통해 적재함으로 수거하며, 상기 블로워의 외측으로는 배출구가 구비됨으로써 적재함을 거치면서 쓰레기와 오물을 낙하하고 난 흡입 공기는 블로워의 강력한 흡입력으로 인해 배출구를 통하여 대기중으로 방출한다.Therefore, each municipality processes roadside garbage using a cleaning vehicle equipped with cleaning equipment. In general, a road cleaning vehicle generates a suction force while a blower operates to remove garbage and dirt on the road surface that the roller brush sweeps. It is collected by a loading box through a suction pipe connected to the inside of the loading box, and an outlet is provided outside the blower, and the intake air that has dropped garbage and dirt while passing through the loading box is discharged into the atmosphere through the discharge hole due to the powerful suction force of the blower. .

이와 같은 노면청소차는 적재함으로 수거된 쓰레기 및 오물 등은 도 1과 같이 적재함(1)의 상부에 설치된 더트스크린(1a)에 걸리면서 하방으로 낙하되고, 흡입공기는 상기 더트스크린(1a)을 통과하여 적재함(1) 상측의 배기통로(2) 및 블로워(5)와 연결된 배기덕트(3)를 경유하여 블로워(5)로 유입된다.Such a road cleaning vehicle is trash and dirt collected by the stacking load is dropped downward while being caught by the dirt screen (1a) installed on the upper portion of the stacking box 1 as shown in Figure 1, the suction air passes through the dirt screen (1a) It flows into the blower 5 via the exhaust passage 2 and the exhaust duct 3 connected to the blower 5 above the loading box 1.

본 발명의 고정형 세척유닛(100) 및 회전형 세척유닛(200)은 도 2 내지 도 3과 같이 배기슈트(4)의 상측 부분과 연결된 배기덕트(3)의 전면판(3a)에 설치됨으로써 상기 배기덕트(3)의 전체 영역에 골고루 물을 분사하면서 적층되거나 고착된 이물질을 물 세척으로 효과적으로 제거함을 특징으로 한다.The fixed washing unit 100 and the rotating washing unit 200 of the present invention are installed on the front plate 3a of the exhaust duct 3 connected to the upper portion of the exhaust chute 4 as shown in FIGS. While spraying water evenly over the entire area of the exhaust duct (3), it is characterized in that the foreign matter is effectively removed by washing with water.

이를 위한 고정형 세척유닛(100)은 상기 전면판(3a)에 원통형의 세척유닛 하우징(110)이 전면판(3a)의 내외부를 관통하여 일체로 고정 설치되고, 상기 세척유닛 하우징(110)에는 중앙에 통수공(121)이 양측으로 관통 형성된 고정어댑터(120)가 나사결합 설치되며, 상기 고정어댑터(120)의 통수공(121) 양단에는 각각 세척수호스가 연결되는 세척수니플(150) 및 세척수노즐(160)이 나사결합 설치됨으로써 상기 세척수니플(150)을 통해 유입되는 물은 통수공(121)을 경유하여 세척수노즐(160)을 통해 배기덕트(3)의 내부로 분사되어 이물질을 물 세척으로 제거할 수 있게 된다.The fixed washing unit 100 for this purpose is a cylindrical washing unit housing 110 to the front plate (3a) is integrally fixed to pass through the inside and outside of the front plate (3a), the washing unit housing 110 in the center The fixing adapter 120 is formed by screwing the through-hole 121 is penetrated to both sides, the washing water nipple 150 and the washing water nozzle is connected to both ends of the water supply hole 121 of the fixed adapter 120, respectively. Since the 160 is screwed and installed, the water flowing through the washing water nipple 150 is sprayed into the exhaust duct 3 through the washing water nozzle 160 via the water hole 121 to wash the foreign matter into the water. It can be removed.

상기 고정형 세척유닛(100)은 본 발명에서 한 쌍이 상호 이격된 상태로 설치되었지만 반드시 이에 한정되는 것은 아니며, 상기 배기덕트(3)의 규격에 따라 개수를 달리하여 설치할 수 있다.The fixed washing unit 100 is installed in a state in which the pair is spaced apart from each other in the present invention, but is not necessarily limited to this, it can be installed by varying the number according to the specification of the exhaust duct (3).

여기에서 상기 세척수노즐(160)은 부채꼴의 형상으로 이루어짐으로써 세척수를 부채꼴 형태로 넓게 수평상으로 분사함으로써 배기덕트(3)의 대부분 영역에 물을 원활하게 분사할 수 있게 된다.Here, the washing water nozzle 160 is formed in the shape of a fan, so that it is possible to smoothly spray water to most areas of the exhaust duct 3 by spraying the washing water in a horizontal shape in a fan shape.

여기에서 상기 고정형 세척유닛(100)은 수평상으로 물을 분사함으로써 상기 배기덕트(3)의 바닥면이나 상부면에 달라붙은 이물질을 완벽하게 제거하기에는 다소 미흡한 점이 우려됨을 적극 고려하여 본 발명에서는 상기 고정형 세척유닛(100)에 더하여 자유롭게 회전하면서 물의 분사각을 수직이나 경사상태로 조절할 수 있는 회전형 세척유닛(200)이라는 기술구성이 추가로 접목된다.In the present invention, the fixed washing unit 100 is sprayed with water in a horizontal manner to consider that it is somewhat insufficient to completely remove the foreign matter stuck to the bottom or top surface of the exhaust duct (3) in the present invention In addition to the stationary washing unit 100, the technical configuration of the rotary washing unit 200 that can adjust the spray angle of the water in a vertical or inclined state while freely rotating is further grafted.

이를 위한 회전형 세척유닛(200)은 상기 고정형 세척유닛(100)의 사이에 위치하는 전면판(3a)에 원통형의 세척유닛 하우징(210)이 전면판(3a)의 내외부를 관통하여 설치된다.In the rotary washing unit 200 for this purpose, a cylindrical washing unit housing 210 penetrates the inside and outside of the front plate 3a on the front plate 3a positioned between the fixed washing unit 100.

이때 상기 세척유닛 하우징(210)은 도 6과 같이 외측 선단에 고정플랜지(211)가 일체로 돌출 형성됨으로써 전면판(3a)의 외면에 고정플랜지(211)를 용접작업 등을 통해 일체로 부착할 수 있고, 상기 고정플랜지(211)의 타측 방향의 내측 선단에는 걸림플랜지(212)가 내향으로 돌출 형성됨으로써 상기 세척유닛 하우징(210)의 내부에 삽입 설치되는 베어링부싱(220)은 상기 걸림플랜지(212)에 밀착된 상태를 유지하면서 외부로 이탈되지 않고 안정적으로 수납될 수 있게 된다.At this time, the washing unit housing 210 is integrally protruded to the outer end of the fixing flange 211 as shown in Figure 6 to be integrally attached to the fixing flange 211 to the outer surface of the front plate (3a) through a welding operation or the like. The locking flange 212 may be inserted into the washing unit housing 210 so that the locking flange 212 protrudes inwardly at an inner end of the fixing flange 211. 212) can be stably stored without being separated to the outside while maintaining a state in close contact.

상기 베어링부싱(220)은 회전어댑터(230)가 원활하게 회전할 수 있도록 마찰저항을 줄여주면서 회전지지하는 역할을 수행하는 것으로, 내측 선단에는 상기 회전어댑터(230)가 외부로 이탈됨을 방지하는 걸림플랜지(222)가 내향으로 돌출 형성된다.The bearing bushing 220 serves to support the rotation while reducing the frictional resistance so that the rotation adapter 230 can rotate smoothly, the inner end of the bearing bushing 220 to prevent the rotation adapter 230 is separated to the outside The flange 222 protrudes inwardly.

따라서, 상기 베어링부싱(220)의 내부에 회전가능하게 끼움 설치되는 회전어댑터(230)는 외주면에 일체로 돌출형성된 회전돌부(235)가 상기 걸림플랜지(222)에 밀착된 상태를 유지함으로써 외부로 이탈되지 않고 원활하게 회전할 수 있게 된다.Therefore, the rotary adapter 230 rotatably fitted in the bearing bushing 220 is rotated to the outside by maintaining a state in which the rotating protrusion 235 integrally formed on the outer peripheral surface in close contact with the engaging flange 222. It can be rotated smoothly without falling off.

그리고 상기 세척유닛 하우징(210)의 일측 선단에는 상기 회전어댑터(230)의 외측에 끼워지는 하우징커버(240)가 볼팅작업을 통해 일체로 부착됨으로써 상기 회전어댑터(230)는 회전돌부(235)의 양측이 각각 걸림플랜지(222) 및 하우징커버(240)에 의해 이동 저지되어 더욱 안정적으로 회전작동할 수 있게 된다.In addition, a housing cover 240 fitted to an outer side of the rotary adapter 230 is integrally attached to the front end of the washing unit housing 210 through a bolting operation so that the rotary adapter 230 of the rotary protrusion 235 is formed. Both sides are respectively prevented by the locking flange 222 and the housing cover 240 to be rotated more stably.

상기 회전어댑터(230)는 중앙에 통수공(231)이 양측으로 관통하여 형성되고, 상기 통수공(231)의 양단에 각각 세척수니플(250) 및 세척수노즐(260)이 설치됨으로써 상기 세척수니플(250)을 통해 유입되는 물은 통수공(231)을 경유하여 세척수노즐(260)을 통해 배기덕트(3)의 내부로 분사되어 이물질을 물 세척으로 제거할 수 있게 된다.The rotary adapter 230 is formed by passing through the water hole 231 at both sides, the washing water nipple 250 and the washing water nozzle 260 are installed at both ends of the water supply hole 231, the washing water nipple ( Water introduced through the 250 is sprayed into the exhaust duct 3 through the washing water nozzle 260 via the water supply hole 231 to remove foreign substances by washing the water.
