Lawn leaf sweeper

Abstract

The invention relates to a lawn leaf sweeper. A hand-propelled walking mode is adopted; when a front wheel of the sweeper rotates, a drum in front of the sweeper is driven to rotate through chain transmission, the drum drives a rake rolling needle on the drum to rake leaves, the leaves are pushed into a suction port along a lower housing plate of the drum, and rake teeth at the suction port rake the leaves into a collecting box; leaf collecting power is mainly supplied by a petrol engine; the petrol engine drives an impeller to rotate through a belt; the leaves are absorbed into the collecting box under the action of negative pressure produced by the rotation of the impeller; and after the collecting box is filled with leaves, the leaves automatically enter a detachable movable collecting box which is connected to the back of the collecting box under the action of the impeller power, so that leaf collection is completed. In the sweeper, more human-friendly treatment is adopted, the rotating speed of the drum is increased according to the walking speed of a person, and power needed by the impeller for absorbing the leaves, namely the power of the petrol engine is calculated according to a walking distance, so that the labor of cleaning workers is reduced while time saving and high efficiency are ensured.

Description

technical field [0001] The invention relates to a sweeping mechanism, in particular to a lawn leaf sweeper. Background technique [0002] How to remove the fallen leaves on the lawn has always been a headache: the fallen leaves are mixed in the grass, manual cleaning is time-consuming and labor-intensive, and the effect is also very general, and large-scale machines are powerless to small pieces of lawn.

Problems solved by technology

[0002] How to remove fallen leaves from the lawn has always been a troublesome problem: fallen leaves are mixed in the grass, manual cleaning is time-consuming and laborious, and the effect is also very general, and large machines are powerless to small pieces of lawn

[0004] But in general, machines that are specially designed for cleaning lawn leaves are relatively rare, and the competition is relatively small; and in essence, there are only large-scale lawn cleaning machines for golf courses and other places on the market, and the models are relatively large; There is no organization for cleaning up small and medium-sized lawn leaves in schools, residential quarters, etc.
