The greening fallen leaf cleaning device is mainly used as environment-friendly cleaning equipment, can be used for collecting cleaned leaves, is particularly convenient to use for cleaning fallen leaves falling on greenbelt plants, and can also be used for cleaning and collecting light scattered garbage such as catkin poplar catkins and the like. When the device is used, positive pressure gas is blown into a gas blowing cavity between the gas inlet pipe 3 and the gas suction pipe 31 through a pipeline by the blower 2, then high-pressure gas is blown out forwards from a gas blowing opening position in the front part of the gas blowing cavity, at the moment, air in the front part of the gas suction pipe 31 is taken away by the gas flow blown out from the gas blowing opening, so that negative pressure is generated in the front part of the gas suction pipe 31, the gas suction effect is generated on the gas suction pipe 31, the suction negative pressure is transmitted to the leaf suction head 7 from the hose 5 and the leaf suction pipe 6, and the leaf suction head 7 can suck leaves through an air inlet, in the process of sucking the leaves, the leaves are blown out from the gas suction pipe 31, the pressurization of the gas blowing cavity in the gas inlet pipe 3 enables the gas flow to be larger, the leaves are blown out from the end part of the gas inlet pipe 3 into the mesh-shaped pipe 4 at a higher, make the leaf downstream under the restriction of net class body on netted pipeline 4, and large granule grit and dust in the leaf blow off from netted pipeline's the department of buckling, guaranteed the cleanness of the leaf in the entering leaf dropping box 1, the lower part application of the leaf of being convenient for.

The device can also be used for sucking and collecting catkins, poplar catkins and the like. The device provides the power of bleeding through air-blower 2, and the structure is simplified greatly to traditional structure of bleeding relatively, can accomplish through the processing of the air-blower of standard and simple pipeline frame box structure, the low price more of cost. The device makes large piece class rubbish materials such as leaf can get into smoothly fall leaf case 1, intake pipe 3 and exhaust tube 31's parcel design not only makes the process of bleeding go on unimpededly, more sufficient the leaf of making can be taken away fast at the anterior position air current power of giving vent to anger of intake pipe 3 simultaneously, greatly reduced pile up the emergence of jam in the pipeline, also can not have the leaf and bleed the impeller contact and produce phenomenons such as kinking for the more stability of the device working process. And meanwhile, even if the whole air suction pipeline is blocked, the air blower 2 can still work normally, so that the use is safer.

In the specific design, as shown in fig. 1, the front portion of the air inlet pipe 3 is designed to be conical, and an air blowing port between the air suction pipe 31 and the air inlet pipe at the front portion of the air inlet pipe 3 is opposite to an oblique side edge of the conical pipe. At this time, the air flow passage is narrowed by the air outlet of the tapered tube in the front of the air inlet tube 31, the air flow strength is higher, and meanwhile, the air blown out forward from the air blowing cavity flows to the middle position of the axis, so that the air in the air exhaust tube 31 is easier to be wrapped and carried away, the suction force generated on the air exhaust tube 31 is higher, and the air exhaust efficiency is higher.

In the specific design, as shown in fig. 1 and fig. 2, the working surface of the suction blade head 7 is a plane, the air inlet of the suction blade head 7 is designed to be rectangular, and the part of the suction blade head 7 outside the air inlet is designed with a blade sweeping brush 71 perpendicular to the working surface of the suction blade head 7. The planar design of the working surface of the leaf sucking head 7 is more convenient for the extraction of sheet or flocculent objects such as leaves at an approximate plane position, and meanwhile, the design of the leaf sweeping brush 71 is convenient for the falling leaves falling on the upper part of the green plants to be hooked out through the leaf sucking head 7, so that the falling leaves are easier to be sucked away by the leaf sucking head 7.

The leaf dropping box 1 is in a cuboid shape, the idler wheels 11 are universal wheels, so that the device can be pushed forwards, backwards, leftwards and rightwards conveniently, and meanwhile, a push rod convenient to push and pull can be arranged on the leaf dropping box 1. The rollers 11 are assembled at the lower parts of four bottom corners of the leaf falling box 1, and the rollers 11 are assembled at the lower part of the blower 2, so that the stress is more balanced.

In specific implementation, as shown in fig. 1, the lower part of the flabellum 1 is made of a mesh material, the flabellum 1 is communicated with the lower part, and the air outlet net 12 and the flabellum 1 are designed in a mesh structure, so that air blown into the flabellum 1 from the air suction pipe 3 is easier to discharge, and the flabellum is easier to fall into the flabellum from the mesh pipeline 4. The air outlet net 12 is hinged with the leaf falling box 1. Therefore, the air outlet net 12 not only has the air outlet function, but also can be used as a switch door for removing leaves in the leaf box 1, and is more convenient for removing the fallen leaves.

In the specific design, the vane-pumping pipe 6 adopts an internal and external sliding sealed double-pipe structure, and the internal and external double-pipes of the vane-pumping pipe 6 can be pulled back and forth relatively along the axial direction to change the length. The suction vane pipe 6 is used as a suction passage, and meanwhile, when people normally perform vane removing work, the suction vane pipe 6 can be held by people, and due to the drawing design of the suction vane pipe 6, the suction vane head 7 can reach the suction vane position more easily, and the use is more convenient.

As shown in fig. 1, an arc-shaped collecting net 8 is designed at the upper part of the leaf dropping box 1, and the arc-shaped edge of the collecting net 8 faces the front part of the air inlet pipe 3. Thus, impurities such as sand blown out from the air inlet pipe 3 to the mesh-shaped pipeline 4 can directly fall into the collecting net, so that the device can collect solid particle impurities while absorbing fallen leaves through the collecting net.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
