Abstract
A mini-tiller speed changing box spindle assembly structure comprises a spindle and a gear, wherein an outer spline which is meshed with a gear is arranged on the surface of the spindle; retainer rings which are used for preventing the gear from being separated from the outer spline are arranged on the spindle and on two sides of the outer spline; a shaft hole with an inner spline is formed in the inner edge of the gear; the gear is inlaid in the outer spline of the spindle through the shaft hole and is a multi-linkage gear; a radial blind hole is formed in a portion, which is combined to the spindle, of the multi-linkage gear; a spring and a steel ball are arranged in the blind hole; and a slot which is matched with the blind hole is formed in the spindle. By the mini-tiller speed changing box spindle assembly structure, the shortcoming that the traction force of a mini-tiller is small in a complex environment is overcome, and the cultivation efficiency is improved.
Description
Technical field
The present invention 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 have that plot is little, the discrepancy in elevation large according to the farmland in the vast hills of China and mountain area, without the feature of tractor road, be orchard, vegetable plot, warmhouse booth, hilly upland and the operation of fritter field and the small-scale agricultural machinery that designs specially.It has lightweight, and volume is little, and structure is simple, easy to operate, and for ease of maintenaince, working stability is reliable, and long service life, oil consumption is low, manufacturing efficiency high.Its speed variator system adopts the speed changing structure of the duplex-gear movement in gearshift drive main spindle mostly.This structure gear is less, and speed changes underaction, and under complex environment, tractive force is not enough.
Summary of the invention
For in prior art, on main shaft, speed change gear is less, draws hypodynamic technical problem under complex environment, the invention provides a kind of gear box of micro-cultivator main shaft assembly structure, this structure, by arranging multi-joint tooth, adds shift scope, draws hypodynamic problem under solving complex environment.
To achieve these goals, present invention employs 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 arrange back-up ring for preventing gear from departing from external splines, described gear inner edge is 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, radial blind hole is provided with on described gear, with main shaft junction, be provided with spring and steel ball in blind hole, described main shaft is provided with the draw-in groove coordinated with blind hole.
Preferably, described gear is three teeth.
Preferably, described outer gear rim is arranged gearshift chuck, 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.
Advantageous Effects of the present invention is: gear box of micro-cultivator main shaft assembly structure of the present invention has set up shift scope, microtilling machine can be made to meet the requirement of multiple ploughing speed, solve the technical problem of the deficiency of tractive force under microtilling machine complex environment simultaneously, improve and cultivate efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, gear box of micro-cultivator main shaft assembly structure, the gear 2 comprising main shaft 1 and be arranged on main shaft 1.
As shown in Figure 1, the outer surface in main shaft 1 stage casing is arranged and is used for the external splines 3 of engaging gear 2, on main shaft 1, external splines 3 place arranges the draw-in groove 11 being used for limiting gear 2 and moving axially, and draw-in groove 11 is set to three, be arranged in parallel and spacing is equal, each draw-in groove 11 represents a gear.
As shown in Figure 1, on main shaft 1, the both sides of external splines 3 arrange the back-up ring 4 for preventing from departing from 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, arranges the blind hole 22 of the radial direction coordinated with draw-in groove 11 on triple gear, with main shaft 1 junction, is provided with spring 5 and steel ball 6 in blind hole 22.
What finally illustrate is, above embodiment is only in order to illustrate technological scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technological scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
