摘要： A blade for a rotating blade assembly for a mower implement is positioned between a disc and a spring plate. The blade includes a body defining a pin aperture. A retaining pin includes a shaft portion that defines a shaft diameter and extends through the pin aperture of the blade. The retaining pin is engaged with a mounting aperture of the disc and a pocket of the spring plate. The body of the blade includes a radially inner edge relative to a rotation axis of the disc. The body defines a tail length between the pin aperture and the radial inner edge. The tail length is equal to or greater than seventy five percent of the shaft diameter of the shaft portion of the retaining pin and/or the pin aperture of the blade. The pin aperture of the blade is less than 105% the shaft diameter of the retaining pin.

摘要： A grass cutting mobile robot includes a body and a blade assembly connected to the body and rotatable about a drive axis. The blade assembly includes blades, a housing to hold the blades, and a spring that connects the blade to the housing. The housing includes a slot in which to mount a blade so that a portion of the blade is movable through the slot towards another blade in response to an impact. The slot slopes upwards in the housing towards the body, thereby enabling the blade to move upwards relative to a ground surface toward the body in response to the impact. The spring is for constraining movement of the blade relative to the housing.

摘要： The present disclosure relates to a lawn mower robot, including an inner body; an outer cover configured to surround an outer side of the inner body; wheels rotatably mounted at both sides of the inner body, respectively; a rotating plate rotatably mounted on a bottom surface of the inner body, and disposed to be inclined downward with respect to a horizontal plane in a traveling direction of the inner body; a plurality of blades spaced apart from each other in a circumferential direction of the rotating plate to cut grass while rotating around a rotation shaft of the rotating plate; and a blade protection cover formed to be spaced apart from the blades to prevent a fragment generated due to a collision with the blades from being thrown out of the outer cover, wherein the blade protection cover comprises a plurality of protrusion portions spaced apart from each other on a circular arc in front of a blade protection cover body, and a distance between the plurality of protrusion portions is formed to be smaller toward both side end portions with respect to a front-rear directional center line of the blade protection cover.

摘要： The present invention relates to a shock-absorption type mower safety blade unit having a protector mounted thereon, the safety blade unit comprising: a housing fixed to a driving shaft of a driving part, provided at the end portion of an operating bar of a mower, so as to rotate together with the driving shaft; a plurality of cutter parts, which are provided at the housing, and project to the outside of the housing so as to cut weeds according to the rotation of the housing and retract to the inside of the housing so as to prevent breakage when colliding with obstacles; and an elastic part for providing elastic force to the cutter parts such that the cutter parts can return by projecting outwards when the cutter parts retract into the housing. The shock-absorption type mower safety blade unit having a protector mounted thereon, according to the present invention, prevents pebbles from being scattered or the cutter parts from being damaged because of the cutter parts retracting to the inside of the housing when colliding with the pebbles or a structure, since the cutter parts are provided to be retractable into the housing and the elastic part supports the cutter parts such that the cutter parts project outward from the housing, and improves mowing efficiency by hitting plants with greater force due to the elastic force provided from the elastic part, when colliding with large plants.
摘要翻译：本发明涉及一种具有安装在其上的保护器的减震型割草机安全叶片单元，该安全叶片单元包括：固定到驱动部件的驱动轴上的壳体，该壳体设置在割草机的操作杆的端部以与驱动轴一起旋转; 多个切割器部件，其设置在壳体处并且突出到壳体的外部，以便根据壳体的旋转切割杂草并且缩回到壳体的内部，以便当与障碍物碰撞时防止破损 ; 以及弹性部件，用于向切割器部件提供弹力，使得当切割器部件缩回到壳体中时，切割器部件能够通过向外突出而返回。根据本发明，其上安装有保护器的减震型割草机安全刀片单元防止由于在与卵石碰撞时切割器部分缩回到壳体内部而引起卵石散落或切割器部件损坏或结构，因为切割器部件设置为可缩回到壳体中，并且弹性部件支撑切割器部件，使得切割器部件从壳体向外突出，并且通过由于弹力而以更大的力击打植物来提高割草效率当与大型植物碰撞时由弹性部分提供。
