Embodiment Construction
[0032] A lawn leaf sweeper, such as figure 1 and figure 2 Shown, comprise car body 9, install push arm 1, wheeled traveling mechanism, fallen leaf raking mechanism and fallen leaf collecting mechanism on it;
[0033] The running mechanism includes two identical front wheels 6 and two rear wheels 3, with an outer diameter of 200mm, an inner diameter of 150mm, an inner center hole diameter of 12mm, and a number of spokes of 5. The walking mode adopts the hand-push type, which is convenient and convenient while saving energy, embodying the concept of environmental protection, labor-saving and convenient.
[0034] The leaf raking mechanism is located in front of the front wheel 6 of the running mechanism, and includes a drum 8, a cover plate and a transmission chain 7; the drum 8 is 350 mm long, its outer diameter is 112 mm, and its wall thickness is 5 mm. Five rows of rake-type needle rollers 81, the rake-type needle rollers 81 are bent downward at 135° at the end away from th...

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. [0003] There are already many similar related cleaning products in China, and there are mainly large-scale machinery for cleaning the road, automatic sweepers, sweepers, sweepers, dust-free sweepers, sweepers, road sweepers, road sweepers There are many kinds of electric sweepers, snowplows, lawn repair machines, garbage collection vehicles, etc., and the main power supply forms of these machines are also various, some are electric motors, some are gasoline engines, and their walking forms are even more diverse. , some are self-propelled, some are portable, and some are h...
