When existing work, existing lawn mower causes the overheated problem of electric member due to the combination of high broaching load, high ambient temperature or both of these case, overheated electronic device and the particularly serviceability of lithium battery of battery of affecting, automatic lawn trimmer is like this especially.Common most of the time of lawn mower or institute are if having time under the outdoor sun, in the situation that using lithium battery, electronic device is usually configured to for prevent that in the time that battery unit is on a certain limiting temperature product operation, object from being prevent permanent damages or catch fire under extreme case.Therefore, need to add cooling device to these devices, as reached certain cooling effect by the wind-force effect of blade of rotating, but lower owing to offering the power of cutting blade in this trimmer, only cooling by blade rotation is inadequate; Also can increase cooling fan, but need other power requirement when fan operation, also can take larger space.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of centrifugal cutterhead and mower, at the integrated blade in cutterhead top, when mowing, thereby can make mower internal control circuit plate and motor realize air circulation and reach cooling object, make cutterhead frame produce up and down pressure differential simultaneously, form microcirculation, by discharges such as grass bits, dusts, reach dust-proof effect.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: centrifugal cutterhead, comprise cutterhead body, and the end face of described cutterhead body has some blades, described blade shroud Rao Yi center is divergent shape and distributes, the integrative-structure that described cutterhead body and blade are formed in one.
Simultaneously, the invention provides a kind of mower, comprise casing and be installed on the blade assembly on casing, described blade assembly has cutterhead, the driving mechanism for driving cutterhead to rotate being connected with cutterhead is installed on described casing, and described cutterhead is centrifugal cutterhead as above.
As preferably, the cutterhead frame exposing to below, casing bottom surface is installed on described casing, the bottom surface of described casing has hole, the top of described cutterhead frame has the cylinder stretching in hole, described cutterhead is positioned at the below of cutterhead frame, described driving mechanism comprises the motor being arranged in cylinder, and the output shaft of described motor extends cutterhead frame below and is connected with cutterhead.
As preferably, described cylinder stretches into Kong Zhongyu casing and is slidably matched.
As preferably, on the outer wall of described cylinder, be provided with slide block, on the inwall in described hole, be provided with the chute being slidably matched with slide block, between described cylinder and casing, coordinate to realize by slide block and chute to be slidably matched.
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 arranges 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:
Centrifugal cutterhead and mower that the present invention adopts technique scheme to provide, at the integrated blade in cutterhead top, when mowing, thereby can make mower internal control circuit plate and motor realize air circulation and reach cooling object, make cutterhead frame produce up and down pressure differential simultaneously, form microcirculation, by discharges such as grass bits, dusts, reach dust-proof effect; 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, 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.
