Abstract
The utility model discloses a spindle assembly structure of a gearbox of a mini-tiller. The spindle assembly structure comprises a spindle and a gear. An external spline which is used for being meshed with the gear is arranged on the surface of the spindle, retainer rings which are used for preventing the gear from being separated from the external spline are arranged on the spindle and are positioned on two sides of the external spline, a shaft hole with an internal spline is formed in the inner edge of the gear, the gear sleeves the external spline on the spindle via the shaft hole and is a multi-gear block, radial blind holes are formed in a joint of the multi-gear block and the spindle, springs and steel balls are arranged in the blind holes, and clamp grooves which are matched with the blind holes are formed in the spindle. The spindle assembly structure has the advantages that the problem of insufficient tractive force of an existing mini-tiller in complicated environments can be solved, and the tillage efficiency can be improved.
Description
Technical field
The utility model relates to a kind of agricultural equipment technical field, particularly a kind of gear box of micro-cultivator main shaft assembly structure.
Background technique
Microtilling machine be according to the farmland in the vast hills of China and mountain area have that plot is little, the discrepancy in elevation is large, without the feature of tractor road, the small-scale agricultural machinery designing for orchard, vegetable plot, warmhouse booth, hilly upland and the operation of fritter field specially.It has lightweight, and volume is little, simple in structure, easy to operate, and for ease of maintenaince, working stability is reliable, long service life, and oil consumption is low, manufacturing efficiency high.The speed changing structure that its speed variator system adopts the duplex-gear in gearshift drive main spindle to move mostly.This structure gear is less, and speed changes underaction, tractive force deficiency under complex environment.
Model utility content
In prior art, on main shaft, speed change gear is less, draws hypodynamic technical problem under complex environment, the utility model provides a kind of gear box of micro-cultivator main shaft assembly structure, this structure, by multi-joint tooth is set, has increased shift scope, has solved and under complex environment, has drawn hypodynamic problem.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of gear box of micro-cultivator main shaft assembly structure, comprise main shaft and gear, the outer surface of described main shaft is provided with the external splines for engaging gear, on main shaft, the both sides of external splines are provided for preventing that gear from departing from the back-up ring of external splines, on described gear inner edge, be provided with the axis hole of internal spline, be nested on the external splines on main shaft by axis hole, described gear is multi-joint tooth, on described gear, with main shaft junction be provided with blind hole radially, in blind hole, be provided with spring and steel ball, described main shaft is provided with the draw-in groove coordinating with blind hole.
Preferably, described gear is three teeth.
Preferably, gearshift chuck is set in described outer gear rim, chuck is flange arrangement.
Preferably, described draw-in groove is set to three, is parallel to each other and is equidistantly arranged on main shaft.
Useful technique effect of the present utility model is: gear box of micro-cultivator main shaft assembly structure of the present utility model has been set up shift scope, can make microtilling machine meet the requirement of multiple ploughing speed, the not enough technical problem that has simultaneously solved tractive force under microtilling machine complex environment, has improved and has cultivated efficiency.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, gear box of micro-cultivator main shaft assembly structure, comprises main shaft 1 and is arranged on the gear 2 on main shaft 1.
As shown in Figure 1, on the outer surface in main shaft 1 stage casing, be provided for the external splines 3 of engaging gear 2, on main shaft 1, external splines 3 places are provided for the axially movable draw-in groove 11 of limiting gear 2, draw-in groove 11 is set to three, be arranged in parallel and spacing equate, each draw-in groove 11 represents a gear.
As shown in Figure 1, on main shaft 1, the both sides of external splines 3 are provided for preventing from departing from the back-up ring 4 of external splines 3.
As shown in Figure 1, gear 2 is triple gear, and the inner edge of triple gear is provided with the axis hole of internal spline, for being connected with main shaft 1; The outer rim of triple gear is provided with chuck 21, and chuck 21 is flange arrangement, on triple gear, the blind hole radially 22 coordinating with draw-in groove 11 is set with main shaft 1 junction, is provided with spring 5 and steel ball 6 in blind hole 22.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
