有益效果:Beneficial effect:
1、该城市建筑园林生态绿化装置,通过第二风扇的离心叶轮的旋转在箱体与外界间产生压力差,通过吸管吸取杂物,在第二电机快速推动下,第二风扇的离心叶轮中的空气将快速排出来,使箱体中的一部分内空气不断填补到扇叶附近,与外部产生较高的压力差,此时,第二风扇的转动产生的风速就造成较高的吸力和压力,在吸力和压力的作用下,空气高速排出,而装置左侧吸管部分的空气不断地补充箱体中的空气,致使箱体内部产生瞬时真空,和外界大气压形成负压差,在此压差的作用下,吸取吸管附近的落叶等杂物。1. The urban building garden ecological greening device generates a pressure difference between the box and the outside world through the rotation of the centrifugal impeller of the second fan, and absorbs debris through the straw. Under the rapid push of the second motor, the centrifugal impeller of the second fan The air will be quickly discharged, so that a part of the air in the box is continuously filled to the vicinity of the fan blades, and a higher pressure difference is generated with the outside. At this time, the wind speed generated by the rotation of the second fan will cause higher suction and pressure. , under the action of suction and pressure, the air is discharged at high speed, and the air in the suction pipe on the left side of the device continuously replenishes the air in the box, resulting in an instantaneous vacuum inside the box, and a negative pressure difference with the external atmospheric pressure. Under the action of the straw, absorb fallen leaves and other sundries near the straw.
2、该城市建筑园林生态绿化装置,通过粉碎装置对箱体内的落叶等小型杂物进行粉碎,在装置使用时,吸取落叶等小型杂物进入箱体,此时,关闭第二电机,使得第二风扇停止转动,吸管停止吸取落叶等小型杂物,打开粉碎装置,粉碎装置设置的第一电机开启,带动粉碎刀片将对箱体内的落叶等小型杂物进行粉碎,粉碎完成后,通过滑板在凹槽内的滑动打开滑板,使得第一风扇打开后,可以对箱体内的粉碎后的杂物进行清理,然后打开挡板,使得第一风扇在清理时,箱体处于通透状态,杂物得以清理出箱体。2. The urban building garden ecological greening device crushes small sundries such as fallen leaves in the box through the crushing device. When the device is in use, it absorbs small sundries such as fallen leaves and enters the box. At this time, the second motor is turned off, so that the first The second fan stops rotating, the suction pipe stops absorbing small sundries such as fallen leaves, the crushing device is turned on, the first motor provided by the crushing device is turned on, and the crushing blade is driven to crush small sundries such as fallen leaves in the box. The sliding in the groove opens the slide plate, so that after the first fan is turned on, the crushed debris in the box can be cleaned, and then the baffle is opened, so that when the first fan is cleaning, the box is in a transparent state, and the debris Can be cleaned out of the box.
3、该城市建筑园林生态绿化装置,通过过滤网的使用保持装置的整洁性,城市建筑园林生态绿化装置在使用时,难免会吸取园林内的灰尘等杂物,在吸管将灰尘等杂物吸取至箱体中后,由于盖板和滑板皆处于关闭状态,形成一个封闭的空间,仅有方形孔可进行空气的流通,且第二风扇位于方形孔的后面,进行空气的吸取作用,使得吸管所吸取的灰尘等杂物只能从方形孔排出,而过滤网的使用,可过滤灰尘等杂物,使得流通的空气中不含灰尘等杂物,保持了第一风扇以及其周边设备的整洁性。3. The urban architectural garden ecological greening device maintains the cleanliness of the device through the use of filters. When the urban architectural garden ecological greening device is in use, it will inevitably absorb dust and other sundries in the garden, and the dust and other sundries will be absorbed by the suction tube After entering the box, since the cover plate and the slide plate are closed, a closed space is formed, and only the square hole can circulate the air, and the second fan is located behind the square hole to suck the air, so that the suction pipe The absorbed dust and other sundries can only be discharged from the square hole, and the use of the filter can filter dust and other sundries, so that the circulating air does not contain dust and other sundries, keeping the first fan and its peripheral equipment clean sex.
