흡입성능을 향상시킨 노면청소차{Road sweeping vehicle having improved suction performance}Road sweeping vehicle having improved suction performance

본 발명은 노면청소시 흙이나 모래에 의해 흡입관이 막히면서 청소효율이 저하됨을 방지함은 물론 상기 흡입관을 통해 흡입되는 미세먼지를 물과 결합시켜 대기중으로 미세먼지가 방출됨을 방지하기 위한 것으로, 흡입마우스의 상측 덕트부에 나선경로를 이루는 분사패턴으로 물을 분사함으로써 형성되는 회전수류가 상기 흡입관의 나선골을 타고 이동하면서 자동으로 흡입관을 세척하도록 하는 기술에 관한 것이다.The present invention is to prevent the suction pipe is clogged by the soil or sand when cleaning the road while the cleaning efficiency is reduced, as well as to prevent the fine dust is discharged into the atmosphere by combining the fine dust sucked through the suction pipe with water, suction mouse The rotating water flow formed by spraying water in the spray pattern forming a spiral path in the upper duct portion of the invention relates to a technique for automatically washing the suction pipe while moving on the spiral bone of the suction pipe.

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 노면 청소차는 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. Generally, a road cleaning vehicle generates a suction force while the blower is operating 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. .

상기 노면청소차는 도로를 주행하면서 흡입관이 쓰레기나 먼지, 이물질 등을 흡입함이 용이하도록 롤러브러시를 회전시켜 청소 대상물을 흡입관에 연결된 흡입마우스 쪽으로 쓸어내는 것이 일반적이다.The road cleaning vehicle generally sweeps a cleaning object toward a suction mouse connected to the suction pipe by rotating the roller brush so that the suction pipe easily sucks garbage, dust, foreign substances, etc. while driving on the road.

이와 같은 흡입관은 통상 굴곡이 용이하도록 나선형의 주름관으로 구성됨으로써 시간이 지날수록 흙이나 이물질, 미세먼지 등이 나선골에 쌓이면서 딱딱하게 고착됨은 물론 이러한 고착물의 부피가 커지면서 흡입관이 막히는 현상이 발생함에 따라 청소대상물을 적재함으로 원활하게 수거할 수 없어 청소효율이 현저하게 저하되며, 이와 같은 흡입관을 세척하기 위해서는 해체작업 등이 요구되므로 많은 시간과 인력이 소요됨으로써 불필요한 예산낭비를 초래하고 있는 실정이다.Such suction pipes are generally composed of spiral corrugated pipes for easy bending, and as time passes, soil, foreign matter, fine dust, etc. accumulate in the spiral bone and firmly adhere to the spiral bones. The cleaning efficiency is remarkably lowered because the objects to be cleaned cannot be collected smoothly, and dismantling work is required to clean such suction pipes, which requires a lot of time and manpower, resulting in unnecessary budget waste.

또한, 미세먼지의 경우 매우 가벼워서 적재함으로 흡입된 경우라도 상기 적재함의 바닥으로 낙하 적재되지 않고 흡입공기와 함께 대기중으로 방출됨에 따라 대기오염을 유발하는 폐단이 있다.In addition, in the case of fine dust is very light, even if sucked into the loading box there is a closed end causing air pollution as it is discharged into the atmosphere with the suction air without falling to the bottom of the loading box.

본 발명은 종래의 기술에 따른 노면청소차가 내포하고 있는 제반 문제점을 적극적으로 해소하기 위한 것으로, 부채꼴노즐을 이용하여 흡입마우스의 내부로 분사한 물이 회전수류를 형성하면서 상기 흡입관의 나선골을 따라 이동하며 흡입관을 자동으로 세척함은 물론 막힘 현상을 방지하도록 함을 발명의 해결과제로 한다.The present invention is to actively solve the problems of the road cleaning vehicle according to the prior art, the water sprayed into the suction mouse using a fan-shaped nozzle along the spiral bone of the suction pipe while forming a rotary flow Moving and automatically cleaning the suction pipe as well as preventing the blockage of the invention as a problem of the invention.

또한, 본 발명은 상기 부채꼴노즐의 각도를 자유롭게 조절하면서 물의 분사각을 최적의 상태로 설정하여 세척작업의 효율성을 증대할 수 있도록 함을 발명의 해결과제로 한다.In addition, the present invention is to solve the problem of increasing the efficiency of the cleaning operation by setting the spray angle of the water to the optimal state while freely adjusting the angle of the fan nozzle.

본 발명은 상기한 과제를 해결하기 위한 수단으로 흡입마우스의 상측 덕트부 외면에 나선경로를 따라 다수의 조절판 고정시트를 일체로 부착하고, 상기 조절판 고정시트에는 노즐 각도조절판을 고정 설치하되 상기 노즐 각도조절판에 형성된 다수의 각도조절공을 관통하는 고정구를 상기 조절판 고정시트에 형성된 고정구 체결공에 나사결합 설치하며, 상기 노즐 각도조절판의 노즐홀더에 나사결합된 부채꼴노즐은 상기 덕트부를 관통하여 내부로 연결 설치하는 기술을 강구한다.According to the present invention, a plurality of control plate fixing sheets are integrally attached to the outer duct part of the suction mouse along the spiral path as a means for solving the above problems, and the nozzle angle adjusting plate is fixed to the control plate fixing sheet, but the nozzle angle The fastener penetrating a plurality of angle adjustment holes formed in the adjustment plate is installed in the fastener fastening hole formed in the adjustment plate fixing sheet, the fan nozzle screwed to the nozzle holder of the nozzle angle adjustment plate is connected to the inside through the duct part Find the technology to install.

본 발명에 따르면, 노면청소시 흙이나 모래에 의해 흡입관이 막히면서 청소효율이 저하됨을 방지함은 물론 상기 흡입관을 통해 흡입되는 미세먼지를 물과 결합시켜 대기중으로 미세먼지가 방출되지 않고 적재함의 내부로 낙하 적재되어 청소효율을 향상하면서도 대기오염을 방지하며, 궁극적으로는 노면청소차의 흡입성능을 획기적으로 향상하는 효과를 제공한다.According to the present invention, the cleaning pipe is prevented from being deteriorated while the suction pipe is clogged by soil or sand when cleaning the road, and the fine dust sucked through the suction pipe is combined with water, so that the fine dust is not discharged into the atmosphere without leaving the inside of the loading box. As it is dropped and loaded, it improves the cleaning efficiency while preventing air pollution, and ultimately improves the suction performance of the road cleaning vehicle.

또한, 상기 부채꼴노즐을 이용하여 흡입마우스의 덕트부에 나선경로를 이루는 분사패턴으로 물을 분사함으로써 상기 덕트부에 형성되는 회전수류는 상기 흡입관의 나선골을 타고 이동하면서 자동으로 흡입관을 말끔하게 세척함은 물론 흡입관의 막힘 현상을 방지하여 청소효율을 획기적으로 향상하는 효과를 제공한다.In addition, by spraying water in the spray pattern forming a spiral path in the duct portion of the suction mouse by using the fan-shaped nozzle, the rotational water flow formed in the duct portion is automatically washed in the suction pipe while moving through the spiral bone of the suction pipe. Of course, it also prevents the clogging of the suction pipe and provides an effect of dramatically improving the cleaning efficiency.

또한, 상기 부채꼴노즐이 설치된 노즐 각도조절판을 회전시키는 간단한 방법으로 부채꼴노즐의 각도를 자유롭게 조절함으로써 물의 분사각을 최적의 상태로 설정할 수 있어 세척작업의 효율성을 더욱 극대화할 수 있는 효과를 제공한다.In addition, by freely adjusting the angle of the fan-shaped nozzle in a simple way to rotate the nozzle angle adjustment plate is installed in the fan-shaped nozzle can be set to the optimum state of the water spray provides an effect that can further maximize the efficiency of the cleaning operation.

A holder through-hole 11 is formed integrally attached to the outer surface of the duct part 1a by a welding operation, and communicates with the nozzle through-hole 1b formed through the duct part 1a, and the holder through-hole 11 is formed. A plurality of fastener fastening holes 12 are formed radially in the center.

상기 조절판 고정시트(10)에 밀착된 상태로 고정설치되는 노즐 각도조절판(20)은 상기 홀더통공(11)에 일측이 끼워지는 노즐홀더(21)가 중앙을 관통하여 설치되고, 상기 노즐홀더(21)를 중심으로 방사상으로 다수의 각도조절공(22)이 형성된다.The nozzle angle adjusting plate 20 fixedly installed in close contact with the adjustment plate fixing sheet 10 is provided with a nozzle holder 21 fitted with one side in the holder hole 11 penetrating through the center thereof, and the nozzle holder ( 21, a plurality of angle adjusting holes 22 are formed radially about the center.

이와 같은 노즐홀더(21)는 양측이 개방된 파이프의 형태로 구성됨으로써 일측에 부채꼴노즐(30)이 나사결합 설치되고, 상기 노즐홀더(21)의 타측에는 세척수를 공급하는 세척수 호스(3)가 연결 설치된다.Since the nozzle holder 21 is configured in the form of a pipe in which both sides are open, the fan-shaped nozzle 30 is screwed on one side, and the other side of the nozzle holder 21 has a washing water hose 3 for supplying the washing water. Connection is installed.

상기 부채꼴노즐(30)은 노즐 구멍을 V형으로 가공하여 긴 구멍에서 물을 선형으로 분사함으로써 도 4와 같이 선형의 분사영역(31)을 형성한다. 따라서, 상기 부채꼴노즐(30)이 설치된 노즐 각도조절판(20)의 경사각을 적절하게 조절함으로써 상기 다수의 부채꼴노즐(30)에서 분사되는 물의 분사영역(31)은 전체적으로 나선경로를 이룰 수 있게 된다.The fan nozzle 30 forms a linear spraying region 31 as shown in FIG. 4 by processing the nozzle hole in a V shape to spray water linearly from the long hole. Therefore, by appropriately adjusting the inclination angle of the nozzle angle adjusting plate 20 in which the fan-shaped nozzle 30 is installed, the spraying area 31 of the water sprayed from the plurality of fan-shaped nozzles 30 can form a spiral path as a whole.

그리고 다수의 고정구(40)는 상기 각도조절공(22)을 관통하여 고정구 체결공(12)에 나사 결합됨으로써 노즐 각도조절판(20)은 조절판 고정시트(10)에 일체로 고정될 수 있게 된다.In addition, the plurality of fasteners 40 are screwed to the fastener fastening hole 12 through the angle adjusting hole 22 so that the nozzle angle adjusting plate 20 can be fixed integrally to the adjusting plate fixing sheet 10.

이때 상기 각도조절공(22)은 고정구 체결공(12)보다 작은 피치를 이루도록 형성됨으로써 상기 고정구 체결공(12)보다 더 많은 개수로 형성된다.At this time, the angle adjusting hole 22 is formed to have a smaller pitch than the fastener fastening hole 12 is formed in a greater number than the fastener fastening hole 12.

따라서, 상기 노즐 각도조절판(20)을 회전작동함에 따라 부채꼴노즐(30)이 함께 회전함으로써 상기 선형의 분사영역(31)을 형성하는 부채꼴노즐(30)의 분사각이 자유자재로 조절됨으로써 물의 분사각을 최적의 상태로 설정하여 세척작업의 효율성을 높일 수 있게 된다.Therefore, as the nozzle angle adjusting plate 20 is rotated, the fan nozzle 30 rotates together, thereby controlling the spray angle of the fan nozzle 30 forming the linear injection zone 31 at will. By setting the blinds in an optimal state, the efficiency of the cleaning operation can be increased.

또한, 본 발명의 노즐통공(1b)은 덕트부(1a)의 외면에 나선경로를 따라 형성되고, 상기 노즐통공(1b)과 연통하는 홀더통공(11)이 형성된 조절판 고정시트(10)는 덕트부(1a)의 외면에 나선경로를 따라 설치됨으로써 각각의 부채꼴노즐(30)은 전체적으로 나선경로를 이루는 분사패턴으로 물을 분사하면서 상향으로 회전수류를 형성할 수 있게 된다.In addition, the nozzle hole (1b) of the present invention is formed along the spiral path on the outer surface of the duct portion (1a), the adjustment plate fixing sheet 10 formed with a holder hole (11) in communication with the nozzle hole (1b) is a duct By installing along the spiral path on the outer surface of the part 1a, each of the fan-shaped nozzles 30 is capable of forming a rotational flow upward while spraying water in the spray pattern forming the spiral path as a whole.

따라서, 상기 회전수류는 흡입력에 의해 상부로 이동하는 과정에서 흡입관(2)의 내벽으로 튕기면서 나선골을 타고 이동하면서 흡입관(2)을 말끔하게 자동 세척함은 물론 각종 수거대상물이 나선골에 쌓이거나 고착됨을 방지함으로써 흡입관(2)이 막히는 것을 효과적으로 방지하게 된다.Therefore, the rotational water flows through the spiral bone while bouncing to the inner wall of the suction pipe 2 in the process of moving upward by the suction force, and automatically cleaning the suction pipe 2 as well as collecting various objects on the spiral bone. It is possible to effectively prevent the intake pipe 2 from being blocked by preventing or sticking.

즉 본 발명은 흡입마우스(1)의 내부에 나선경로를 이루는 분사패턴으로 물을 분사함으로써 자동으로 흡입관(2)을 세척함은 물론 상기 흡입관(2)을 통과하는 가벼운 미세먼지를 흡수하여 일체로 결합됨으로써 미세먼지가 대기중으로 방출되지 않도록 하는 부수적인 효과도 제공할 수 있게 된다.That is, the present invention, by spraying the water in the spray pattern forming a spiral path inside the suction mouse 1 to automatically clean the suction pipe (2) as well as absorb light fine dust passing through the suction pipe (2) integrally The combination can also provide a side effect of preventing fine dust from being released into the atmosphere.
