Description

Fallen leaf cleaning device

Technical Field

The invention relates to the field of cleaning devices, in particular to a fallen leaf cleaning device.

Background

In order to improve and beautify our living environment, people plant greening trees on both sides of roads or in large areas in parks, but the greening trees can generate large-area fallen leaves in late autumn, which brings high load labor capacity for cleaning of sanitation workers. In the prior art, in order to clean large-area fallen leaves, sanitation workers generally blow the fallen leaves to the roadside by using a fan on one side of the road, the fallen leaves with large area are relatively gathered together in this way, and then the fallen leaves with smaller area are cleaned, so that the labor intensity of the workers is reduced.

However, in the actual cleaning process, under the condition that the rain passing road surface is not dry immediately, the leaves are adsorbed on the ground under the action of rainwater, or the leaves and the bottom surface are bonded together under the action of external forces such as wheel rolling and treading by people, and at the moment, when the leaves are cleaned by using the fan, the fan cannot collect the leaves adsorbed or bonded with the ground, so that the ground cleaning effect is poor.

Disclosure of Invention

The invention aims to provide a fallen leaf cleaning device, which is used for solving the problem that fallen leaves cannot be cleaned by adsorbing or bonding the fallen leaves with the ground when a traditional fan is used for cleaning the fallen leaves, so that the fallen leaves are poor in cleaning effect.

In order to solve the problems, the invention provides a fallen leaf cleaning device which comprises a movable trolley, wherein a partition plate is arranged at the middle lower part of the inner side of the movable trolley, the movable trolley is divided into an upper fallen leaf storage area and a lower fan installation area by the partition plate, a fan fixed with the movable trolley is arranged in the fan installation area, a confluence box is also arranged in the fan installation area, a blowing pipe of the fan is fixedly connected with the side of the confluence box and is communicated with the interior of the confluence box, an air outlet channel fixedly connected with the movable trolley is obliquely arranged at the bottom of the front side surface of the movable trolley, one end of the air outlet channel extends into the fan installation area and is fixedly connected with the side surface of the confluence box, the other end of the air outlet channel points to the ground, first picked leaf soft hairs uniformly distributed on the upper side wall of one end of the air outlet channel, which points to the ground, for picking up the fallen leaves, the first leaf fluff of choosing is made by elastic material, first leaf fluff and air-out passageway fixed connection of choosing, first choose the slope setting between leaf fluff and the ground, and first choose the terminal and the ground in close contact with of leaf fluff, the top of air-out passageway is equipped with a collection leaf passageway, the one end of collection leaf passageway sets up in the first outside of choosing the leaf fluff, the other end of collection leaf passageway passes the leading flank of travelling car and the inboard fixed connection of the left and right sides of travelling car, the collection leaf passageway is close to highly being less than between one end on ground and the ground that the air-out passageway is close to ground and the height between one end and the ground that the air-out passageway is close to ground, and the equal contactless in one end and the ground that is close to ground of collection leaf passageway and air-out passageway.

Further, the lower part of collection leaf passageway is equipped with evenly distributed, and runs through the exhaust hole (, be equipped with the fluff of evenly arranging on the inner wall of collection leaf passageway, the fluff all inclines to ground setting, and the inside whirl that produces of lower extreme that the exhaust hole can avoid collection leaf passageway avoids the leaf to fly in the lower extreme of collection leaf passageway and leads to the condition that the fallen leaves fly out collection leaf passageway, and the efficiency that effectual improvement fallen leaves were collected sets up the fluff in the inside of collection leaf passageway, and the fluff can be beated from top to bottom under the effect of wind power, makes fallen leaves and collection leaf passageway inner wall on the collection leaf passageway inner wall produce the clearance, and the wind-force infiltration of being convenient for blows it to the travelling car in the fallen leaves churn district.

Furthermore, a gap is formed between the first picking-up soft bristles, the gap is 10-15mm, the gap can ensure that wind pressure generated by the fan can pass through the gap, and the first picking-up soft bristles are prevented from blocking wind power, so that the cleaning effect of fallen leaves is improved.
