Brief description of the drawings
Brief description of the drawings of the present utility model is as follows：
Fig. 1 is structural representation of the present utility model.
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit, still fall within the utility model
Claim scope claimed.
Embodiment 1：As shown in figure 1, a kind of gear mechanism for vertical axis mini-tiller, including crank shaft output shaft 1 and umbrella
Gear shaft 2, one end of the crank shaft output shaft 1 is provided with clutch assembly 3, is provided with one end of the angular wheel shaft 2
Gear ring 5 with planet tooth 4, the clutch assembly 3 is arranged vertically with the gear ring 5 and clutch assembly 3 is located on gear ring 5
Side, the two gear gear mechanisms with gear changing mechanism are provided between the clutch assembly 3 and gear ring 5.
Wherein, the two gears gear mechanism includes the connecting shaft that both ends connect clutch assembly 3 respectively and planet tooth 4 connects
6, driving tooth 7 and duplicate gear 8 are provided with the connecting shaft 6, is provided with the side of connecting shaft 6 and is connected with gear ring 5
Gear mounting bracket 9, be provided with the gear mounting bracket 9 with connecting shaft 6 be arranged in parallel driven double crosslinking gear shaft 10,
The both ends of the driven double crosslinking gear shaft 10 are respectively arranged with driven duplicate gear A11 and driven duplicate gear B12, the active
Tooth 7 engages with the driven duplicate gear A11；The gear changing mechanism is connected with the duplicate gear 8.
Further describe, above-mentioned gear changing mechanism includes gear shifting rod 13, and one end of the gear shifting rod 13 is provided with shifting fork bar
14, the shift fork 15 that one end is connected with duplicate gear 8 is provided with the shifting fork bar 14.
The utility model so works：When needing neutral, gear shifting rod 13 is rotated to the centre position of connecting shaft 6, is made
Its duplicate gear 8 is in an intermediate position, departs from clutch assembly 3, driven double crosslinking gear shaft 10, then realizes power cut,
So as to realize neutral.
When needing fast gear, gear shifting rod 13 is rotated to lower position, duplicate gear 8 moves up to be combined with clutch assembly 3, this
When, crank shaft output shaft 1 passes to power on clutch assembly 3, duplicate gear 8, connecting shaft 6, planet tooth 4, gear ring 5, umbrella successively
Gear shaft 2, so as to realize fast gear.
