Abstract

Disclosed is a rotary cultivator positive inversion gear box. A bevel gear set of the rotary cultivator positive inversion gear box is installed at the front end of a gear box body, the front end is connected with an output end of a diesel engine, straight gear sets are arranged on a first shaft and a second shaft, an adjusting shifting fork sliding sleeve is installed in the middle portion of the second shaft, convex gears of two end surfaces of the shifting fork sliding sleeve are meshed with positive bevel gears or negative bevel gears which are installed on two edges of the second shaft, and an output gear shaft is arranged below the rear of the gear box body. The rotary positive inversion gear box achieves speed-reducing output optimization which is conducted after passing through the gear box according to the rotation of the diesel engine to enable better torque output under the effective rotating speed of the diesel engine during a working process and show powerful motive power. Positive inversion two-way output control and neutral position control are introduced, and therefore the rotary cultivator positive inversion gear box can be better addapted to different cultivating needs like sugarcane inter-cultivation, ridge busting, string-opening, and hilling, weeding and channel-opening of other crops and the like. The purpose that a farmer only needs one cultivator, and by owning appropriate matching pieces of the cultivator, different cultivating needs of various crops can be satisfied are better satisfied.

Description

Rotovator rotating gearbox

Technical field

This Shi Xin Xing Wataru and a kind of gearbox, the gearbox of especially a kind of rotovator rotating and neutral gear output.

Background technology

The rotary tillage mechanism that is used at present mini-size tillage machine is by some simple gear drives, the power of diesel engine is passed to relevant facility, can only realize the single-direction transmission of fixed drive ratio, its function singleness, the use adaptive surface is narrow, and transmission efficiency is low, can not get suitable power for different tillage requirements and guarantees, inefficiency, working effect is not satisfactory.

The utility model content

The purpose of this utility model provides a kind of rotovator rotating gearbox that can adapt to better different farming needs, as long as have a loom, is equipped with the different farming demands that suitable farm machinery external member just can realize various crops, accomplishes a tractor serves several purposes.

The technical scheme that the utility model Bian gets is:

A kind of rotovator rotating gearbox, comprise gearbox body, gear shaft, gear, it is characterized in that:

bevel gear set

2,3 is installed in gearbox body 5 front ends and connects the diesel engine output, straight-tooth wheels 4,7 are installed on the first axle 1 and the second axle 11, regulation and control shift fork sliding sleeve 9 is installed in the middle part of the second axle 11, the double wedge of shift fork sliding sleeve 9 its biends and the forward bevel gear 8 that is installed in both sides on the second axle 11 or oppositely bevel gear 10 engagements, output gear shaft 20 is installed in gearbox body 5 back lower places.

This rotovator rotating gearbox, maximum advantage is to have realized that rotating the deceleration output of carrying out according to diesel engine behind this gearbox optimizes, better torque output can be arranged under effective rotating speed of diesel engine when making work, make and when carrying out farming, more embody strong impetus, the design has introduced the control of the two-way output of rotating and neutral gear simultaneously, can adapt to better different farming needs, as carrying out the intertillage of sugarcane, broken ridge, start, weeding trench digging of ridging and other crops etc., have a loom as long as satisfy better peasant household, be equipped with the different farming demands that suitable farm machinery external member just can realize various crops, obtain the extensive favorable comment of peasant household.

Description of drawings

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model front view;

Fig. 2 is the vertical view of Fig. 1.

Embodiment

This rotovator rotating gearbox, its structure mainly comprises: be installed in the first horizontal axle 1 of casing front end, be installed in the driven angular wheel 2 on the first axle 1, be installed in the initiative taper generating gear axle 3 that the casing front end connects the diesel engine output, be installed in the active spur gear 4 that is driven by the first axle on the left side of the first axle 1, gearbox body 5, bearing cap 6, the driven spur gear 7 on the second axle 11 of being installed on driving gear 4 connection for transmissions, be installed in forward bevel gear 8 and the reverse bevel gear 10 on both sides on the second axle 11, be installed in the shift fork sliding sleeve 9 at the middle part of the second axle 11, connect the second axle 11 that is contained in box back that drives by key by driven gear 7, be installed on upper cover of speed changing box 12 and the shifting fork bar 13 on casing top, shift fork pole socket 14, declutch shift shaft 15, shift fork 16, be installed in addition the casing rear lower and forward and reverse bevel gear 8, the angular wheel 17 of 10 transmissions, the conical bearing 18 that is used for supporting output gear shaft 20, rotary tillage transmission case body 19, output gear shaft 20, cone bearing 21 parts such as grade form (attaching figure).Each mechanism installation site and power transmission relation are: be connected to the output of diesel engine by the initiative taper generating gear axle 3 that is contained in the gearbox front end, power is reached driven angular wheel 2, pass to the first axle 1 by the internal spline connection of bevel gear 2 again, the first axle 1 reaches initiatively spur gear 4 by spline joint again, active spur gear 4 and driven spur gear 7 engaged transmission, driven spur gear 7 connects by internal spline again passes to the second axle 11 that is installed in the casing rear portion to power, the second axle 11 is connected by internal spline with shift fork sliding sleeve 9 realizes transmission of power, pass through again the control of shifting fork bar 13 and shift fork 15, can be allocated to respectively forward bevel gear 8 or reverse bevel gear 10 1 sides to slip ring sleeve, the shift fork slip ring can be passed to forward bevel gear 8 or reverse bevel gear 10 to power respectively by the double wedge of its biend, realizing that forward and reverse torque power is exported to is installed in the output gear shaft 20 of transferring behind the gearbox body, drive corresponding farm machinery external member by output gear shaft 20 at last, in the time of in the middle of shift fork sliding sleeve 9 places the second axle 11, this moment, gearbox was neutral gear, there is not power to pass to output gear shaft, realization power separates, and so just can finish better various function needs of cultivating.
