Description

Portable and Eco-friendly steam grass weeder

The present invention relates to a lawn mower, and more particularly, it relates to a lawn mower which can improve the usability of a product and safely use the product The present invention relates to a portable eco-friendly steam mower.

In general, lawn mowers are used to remove rice paddies, field beds, tombs and weeds and grass growing around them.

The blade of such a conventional mower is formed in the form of a strip having a through hole that can be fitted to the drive shaft, and is formed with a sharp edge at one side colliding with the grass.

Prior art of conventional lawn mowers Korean Patent Registration No. 10-1030251 discloses a " lawn mowing device ".

Korean Patent Registration No. 10-1030251 discloses a rotary disk formed with a lozenge so as to absorb a shock by supporting a knife when the lawnmower knife is subjected to a strong impact during backwash, A lawn mower knife comprising a lower blade formed by 10-40% longer than the upper blade to remove the upper blade for shearing and / or tree branches and / or roots that are more forceful than the grass and / or lawn mower, A first rotating shaft which is rotatably connected to the disc and rotatably connected to the disc so that when the weaving machine knife meets an obstacle strong enough to tilt back to the bracket, the weaving machine knife is rotatably connected to the weaving machine knife so that the weaving machine knife meets the obstacle, A second rotating shaft which is a rotation center is formed, and a rotating disk and a lawnmower knife And a bracket for connecting the rotary disk and the lawn mower knife.

Prior Art of Other Mowers Prior Art Korean Utility Model Registration No. 20-0393125 entitled " Mowing machine blade "is disclosed.

The Korean Registered Utility Model No. 20-0393125 has a plurality of blades radially provided on a bottom surface of a circular plate formed at the center thereof with a fastening hole coupled to a rotary shaft, and is fixed by rivets so that one end of the blades can be unfolded by a centrifugal force .

Prior Art of Other Mowers Japanese Utility Model Publication No. 06-038435 entitled "Spring type grass cutting blade"

Japanese Utility Model Publication No. 06-038435 discloses a spring-type grass-cutting blade having a structure capable of providing safety by buffering by elastic force upon contact with an uncut grass. However, such a structure has a problem that it is easily damaged due to relatively low structural strength.

Prior Art of Other Mowers Korean Patent Registration No. 10-1317832 entitled " Mowing Blades "and Korean Registered Patent No. 10-1469821 disclose" mowers capable of being easily replaced ".

The lawnmower blade is rotatably mounted on a rotary body mounted on an end of the workbench. The rotating body has a cutting blade whose end portion protrudes outwardly of the rotating body by centrifugal force when rotating.

However, in Korean Patent Registration No. 10-1469821, when a blade for lawn mower protruded by the centrifugal force of the main body rotates the main body at a low speed or when a blade collides with a large-sized plant, the blade is folded inside the main body There is a drawback that the mowing operation is not performed smoothly.

It is also possible to increase the weight of the blade to increase the cutting force on the plant or increase the rotation speed of the main body. In this case, the cutting force is improved. However, when a hard foreign matter collides with the blade, the blade is broken or the foreign material or the blade is splashed An accident may occur.

As described above, in conventional lawn mowers, when a worker can not find a stone or other hard foreign material embedded in the ground, the blade is struck by the blade of the ground or the floor of the ground during the mowing process and the blade is broken, Occasionally, safety accidents such as injuries to workers were caused.
