Description
Technical field
The utility model relate to a kind of for lawn mower, particularly automatically, self-conductance or the centrifugal cutterhead of lawn mower of supporting oneself and adopt the mower of this centrifugal cutterhead.
Background technology
The overheated problem operationally causing electric member due to the combination of high broaching load, high ambient temperature or both of these case deposited by existing lawn mower, the overheated serviceability affecting electronic device and battery particularly lithium battery, robotic lawn mower is like this especially.Lawn mower usual most of the time or institute are if having time under the outdoor sun, when using lithium battery, electronic device prevents product operation when being usually configured to for being on a certain limiting temperature at battery unit, and object prevents permanent damages or catches fire in extreme circumstances.Therefore, additional cooling device is needed to these devices, as the wind-force effect of blade by rotating reaches certain cooling effect, but due to the power being supplied to cutting blade in this trimmer lower, be inadequate by means of only blade rotation cooling; Also can increase cooling fan, but during fan operation, need other power requirement, also can take larger space.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of centrifugal cutterhead and mower, at the integrated blade in cutterhead top, while mowing, mower internal control circuit plate and motor can be made to realize air circulation thus reach the object of cooling, make cutterhead frame produce pressure differential up and down simultaneously, form microcirculation, by discharges such as grass bits, dusts, reach dust-proof effect.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: centrifugal cutterhead, comprises cutterhead body, and the end face of described cutterhead body has some blades, described blade shroud is divergent shape distribution around a center, the integrative-structure that described cutterhead body and blade are formed in one.
Simultaneously, the utility model provides a kind of mower, and comprise casing and be installed on the blade assembly on casing, described blade assembly has cutterhead, described casing is provided with the driving mechanism for driving cutterhead to rotate be connected with cutterhead, described cutterhead is centrifugal cutterhead as above.
As preferably, described casing is provided with the cutterhead frame exposed to casing subjacent, the bottom surface of described casing has hole, the top of described cutterhead frame has the cylinder stretched in hole, described cutterhead is positioned at the below of cutterhead frame, described driving mechanism comprises the motor be arranged in cylinder, and the output shaft of described motor extends below cutterhead frame and is connected with cutterhead.
As preferably, described cylinder stretches into Kong Zhongyu casing and is slidably matched.
As preferably, the outer wall of described cylinder is provided with slide block, the inwall in described hole is provided with the chute coordinated with skid, between described cylinder and casing, coordinate realization to be slidably matched by slide block and chute.
As preferably, the bottom of described cutterhead frame is provided with some protection posts, and described protection post is trapped among around cutterhead body.
As preferably, the integrative-structure that described protection post and cutterhead frame are formed in one.
As preferably, described casing bottom surface is provided with some lengthy motion picture shape ribs, and described rib is arranged around cutterhead frame, and the length direction of described rib is consistent with the direct of travel of mower.
As preferably, the integrative-structure that described rib and casing are formed in one.
Beneficial effect:
The centrifugal cutterhead that the utility model adopts technique scheme to provide and mower, at the integrated blade in cutterhead top, while mowing, mower internal control circuit plate and motor can be made to realize air circulation thus reach the object of cooling, make cutterhead frame produce pressure differential up and down simultaneously, form microcirculation, by discharges such as grass bits, dusts, reach dust-proof effect; By arranging to be positioned at around blade assembly in 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, change the problem that between mower housing bottom surface and ground, gap is larger 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.
