Description

Technical Field

[0001] The utility model relates to the technical field of weeding, in particular to a hand-held lawn mower. Background Art

[0002] After the lawn has grown for half a year, some of the grass leaves at the bottom are covered by other grass leaves and do not participate in photosynthesis, which can easily cause the entire lawn to wither. Over time, it will become moldy and rot. The movable blades of the lawn mower can effectively remove the dead grass layer under the action of mechanical centrifugal force, enhance the lawn's disease resistance, and appropriately reduce the lawn density, improve lawn aeration, and promote healthy growth of the lawn.

[0003] The existing lawn mowers have a mowing blade and a root cutting blade that need to be replaced during use and cannot work together. The blade head needs to be replaced after the mowing is completed before the root cutting work can be performed. This not only increases the workload of the staff, but also leads to low work efficiency. In addition, the mowing blade head of the existing lawn mower cannot be adjusted up and down, and the front end of the machine needs to be lifted when turning, which is quite laborious and is not suitable for use by the general public.

[0004] A hand-push lawn mower is proposed in the patent document with publication number CN207083692U. The device comprises a mower body, a grass baffle and a wheel shaft. A transmission box is arranged at the middle position above the mower body, a push rod seat is arranged at the lower right side of the transmission box, a telescopic rod fixing seat is arranged at the top of the push rod seat, a telescopic rod fixing bolt is arranged on the telescopic rod fixing seat, and a push rod handrail is arranged at the upper right side of the telescopic rod fixing seat. Root cutting work is carried out after mowing the grass, which reduces the workload of the staff, reduces the time and improves the work efficiency. A crushing knife roller is arranged behind the root cutting knife, which can crush the grass roots and longer weeds and discharge them, so that the weeds can be easily decomposed and used as fertilizer to nourish the lawn. The mower blade and the root cutting knife are connected with a connecting rod, and the lifting is controlled by a hydraulic rod. When turning is required, the height of the connecting rod is raised to make the knife suspended in the air, which is convenient for the machine to turn, does not require much effort, and is suitable for a wide range of people.

[0005] However, in the process of combing grass, the device is prone to causing grass fragments to splash, which makes the device have certain limitations.

[0006] For this reason, we urgently need to provide a kind of walk-behind lawn mower. Utility Model Content
