A lawn cleaning machine with height adjustment

Abstract

The invention belongs to the technical field of weeding devices, and particularly discloses a lawn sweeper with an adjustable height. The lawn sweeper comprises a machine body, a cleaning module, a collecting module and a cutting module. The cleaning module comprises a cleaning motor, a rotating shaft, an installing plate, comb teeth and rolling wheels. The cleaning module is used for cleaning away stone type sundries in a lawn. The collecting module comprises a guide rail, a slider, a cylinder, a sweeping block and a collecting box. The collecting module is used for collecting cleaned-away sundries in a concentrated mode. The cutting module comprises a group of staggered cutting units. Each cutting unit comprises a cutting motor, a telescopic rod, a cutting blade and a wheel. The lawn ispruned into a required length through an adjusting device of the cutting module. Grass is carded through the card teeth, and the stone type sundries in the grass are separated out; by arranging a group of cutting blades, the distances of the cutting blades above the ground are consistent under the effect of the telescopic rods when the lawn sweeper encounters a complicated terrain in the weeding process, and the lengths of cut grass are consistent.

Description

technical field [0001] The invention belongs to the technical field of weeding equipment, in particular to a lawn cleaning machine with height adjustment. Background technique [0002] Lawn mowers are also known as weeders, lawnmowers, lawn trimmers, etc. A lawn mower is a mechanical tool for mowing lawns, vegetation, etc. It is composed of a cutter head, an engine, a walking wheel, a walking mechanism, a blade, a handrail, and a control part. The cutterhead is installed on the walking wheel, the cutterhead is equipped with an engine, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, which saves the working time of the weeding workers and reduces a lot of human resources.

Problems solved by technology

[0003] For some lawns that need landscape design, it is necessary to trim the lawn into various patterns or shapes, and often need to cut out lawns of different levels and heights. In the prior art, there have also been weeding machines that can adjust the length of weeding, such as application number A Chinese patent for 201710412334.3 discloses a garden weeder, including a base, a hydraulic automatic lifting device, a weeding device, a wing cutting device, a grass collection box, and a herbicide box. There is a bracket on the right side of the battery panel, the upper part of the bracket is fixed with a hydraulic pump and battery, the lower part of the bracket is equipped with a hydraulic pipeline, the hydraulic pipeline is connected to the hydraulic automatic lifting device, the hydraulic automatic lifting device is fixed on the lower part of the base, and the hydraulic automatic lifting device is connected to the weeding device , equipped with a wing cutting device, and a herbicide box is installed, and a grass collection box is installed at the lower right of the base; this scheme can realize height adjustment, but when encountering undulating lawns, it cannot efficiently fit the terrain for weeding

[0004] At the same time, because there may be some gravel and other debris in the grass, it is difficult to avoid when weeding with a weeder, which may easily cause damage to the cutting blade, and even cause gravel to fly and hurt people.
