Description
Technical field
The utility model relate to a kind of for lawn mower especially for a kind of automatically, protector and the mower of the rotating knife chip cutter of self-conductance, self-supporting lawn mower.
Background technology
In automatic lawn trimmer, traditional rotary lawn mower that motor-driven blade rotates around roughly vertical axis need to arrange safeguard structure around blade, to prevent hurting user in operating process or to approach other people of trimmer.As illustrated in fig. 1 and 2, existing safeguard structure is a barrier formula cover body structure being formed by some connection strap I 03 covering on outside blade assembly 02 is set in the bottom of trimmer casing 01, connection strap I 03 connects by connection strap II 04 on top, the inevitable problem of this safeguard structure is: 1, trimmer its resistance in the time of work is larger, needs automatic pruning machine that larger power is provided; 2, the protective range of barrier formula cover body structure is limited, and when operator or children play, arm, arm, finger etc. very easily stretch in barrier formula cover body from the gap between casing 01 and ground and hurt by blade, and this barrier formula cover body structure has larger potential safety hazard; 3, adopt barrier formula cover body structure, because connection strap length is longer, middle unsettled, only fix at two ends, when mowing, connection strap easily ruptures when resistance is large or cover body encounters ground; 4, this barrier formula cover body structure, for to be arranged on casing 01 by securing members such as bolts, wastes time and energy, and cost of labor is large.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mower guard and mower, around being positioned at blade assembly in mower housing bottom surface, protruding protector is set, change the larger problem in gap between mower housing bottom surface and ground in the past, can prevent from pointing near blade, when mower is mowed simultaneously, rib has elicitation effect to grass, can greatly reduce to drive resistance.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: mower guard, described mowing tool has casing and blade assembly, described blade assembly exposes the below, bottom surface to casing, described mower guard comprises the some protectors of projection in casing bottom surface, described protector is trapped among blade assembly around, is connected and has spacing between two protectors.
As preferably, the integrative-structure that described protector and casing are formed in one.Adopt integrative-structure moulding easy to manufacture, without installation, intensity is good, not fragile.
As preferably, described protector is lengthy motion picture shape rib, and the direct of travel when bearing of trend of described rib is worked with mower is consistent.Around being positioned at blade assembly in the setting of mower housing bottom surface, strip rib is set, the bearing of trend of strip rib is arranged to consistent with the direct of travel of mower, changed in the past that gap between mower housing bottom surface and ground is large, the body part such as operator or child's arm finger easily stretches into the problem that touches cutter head assembly from the gap between mower housing bottom surface and ground; Be arranged to unanimously with the direct of travel of mower due to the bearing of trend of strip rib, while mowing, mower is through to be cut when careless, and rib has elicitation effect to grass and grass can not pushed down; The below of cutter head assembly, without protection is set,, can greatly reduce mower and drive resistance with the protector that covers blade assembly completely without again.
As preferably, the direction of extending from the one end away from blade assembly to blade assembly at rib, described rib increases to the distance of casing bottom surface gradually away from the bottom surface I of one end of blade assembly.Rib forms wedge shaped tip in the one end away from blade assembly, and mower is in the time mowing, and this end, in face of the grass being cut, contributes to further to reduce resistance, more easily grass is dredged.
As preferably, described bottom surface I is cambered surface, adopts the airflow design of cambered surface to dredge better effects if.
As preferably, the cutterhead frame exposing to the below, bottom surface of casing is installed on described casing, described blade assembly comprises the cutterhead being arranged on cutterhead frame and is arranged on the blade on cutterhead, described mower guard also comprises the some protection posts that are arranged on cutterhead frame bottom, and described protection post is trapped among around cutterhead.Protection post on cutterhead frame has protective effect to cutterhead and blade.
As preferably, the integrative-structure that described protection post and cutterhead frame are formed in one.
As preferably, described cutterhead frame has the reinforced company's contact pin being connected with the sidepiece of protection post.When mowing, protection post can not fracture easily.
As preferably, described protector is the some protection posts that are arranged on casing bottom surface.Protector setting is to protection post, also can plays the effect that stops that arm or finger stretch into.
As preferably, described protection post sets in a row, and the direct of travel when bearing of trend of every row's protection post is worked with mower is consistent.
Meanwhile, the utility model also provides a kind of mower, and described mower has mower guard described above.When mower is when lower or bottom surface is on being placed on bottom surface in working order, the bottom surface of protector should be in 38.5mm to the ultimate range on ground, the ultimate range of adjacent two protectors should be controlled in 38.5mm, both sides on direct of travel taking blade assembly in the time that mower is worked are both sides, front and back, both sides are the left and right sides in addition, the bottom surface that is in the protector of the left and right sides of blade assembly is preferably lower than the height of blade assembly, be in the protector of both sides, blade assembly front and back, have at least the distribution of part protector should be outside the scope apart from blade assembly 80mm.
Beneficial effect:
Mower guard and mower that the utility model adopts technique scheme to provide, around being positioned at blade assembly in mower housing bottom surface, some protectors are set, change the larger problem in gap between mower housing bottom surface and ground in the past, when mower is mowed simultaneously, rib has elicitation effect to grass, can greatly reduce to drive resistance.
