Abstract
A double-side transmission rotary cultivator for hand tractor, a power input shaft connected with an output shaft of the hand tractor drives drive chain wheels symmetrically arranged at two sides by a transmission shaft, the drive chain wheels drive driven chain wheels by drive chains, driven chain wheels arranged symmetrically are mounted at two sides of a knife shaft, chain wheel case covers are provided outside the chain wheels and the chains, a rotary cultivator cover plate is provided outside the knife shaft. the output power is smooth and steady, and the operation is convenient and reasonable. The chain wheel case covers adopt stamping parts, the volume is small, the weight is light, and the fabricating cost can be reduced, during being used for working in the field, the operation torque of the single side structure can not generate.
Description
Technical field
The utility model relates to the bilateral driving rotary cultivator of farmland operation rotovator, particularly hand tractor.
Background technology
In the prior art, this type of rotovator in the past adopts side transmission, its complex structure, manufacturing cost height; And its anisopleual weight is unbalanced, and moment of torsion in use easily takes place.For preventing its generation moment of torsion, when design, need install support bar additional, use double-row bearing, cause installing complexity, bearing shortening in service life influences product quality, increases cost.In addition, this type of rotovator is for reducing moment of torsion, and its arm of force can not be excessive, causes the rotovator working width to reduce.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provide a kind of hand tractor bilateral driving rotary cultivator, as a kind of new structure in the rotovator, its core technology is the drive sprocket of power transmission shaft both sides and the driven sprocket realization both sides synchronization action of cutter shaft both sides, finishes ploughing work.Outputting power is steady, and is rational in infrastructure easy to operate.
The purpose of this utility model realizes by following measure, the bilateral driving rotary cultivator of a kind of hand tractor, the power input shaft of hand tractor output shelves axle connection gear-box 1, travelling gear 2 in the casing is by the drive sprocket 4 of power transmission shaft 3 transmission bilateral symmetry configuration, drive sprocket 4 is by driving chain 5 driven transmission sprocket wheels 7, the driven sprocket 7 of balanced configuration is contained in cutter shaft 8 both sides, and sprocket wheel case lid 6 is equipped with in sprocket wheel and chain outside, and the rotovator cover plate is equipped with in cutter shaft 8 outsides.This device is after power output, and the driving and driven sprocket wheel in the rotovator left and right sides rotates simultaneously to realize the rotovator synchronization job.By the power of hand tractor output, to reach dynamic balnce output, realize the effect of the steady operation of rotovator through bilateral chain Synchronous Transmission.
Above-mentioned power transmission shaft 3 length a=600-1800mm, cutter shaft 8 operation length b=600-1800mm.
Above-mentioned cutter shaft 8 two ends connect driven sprocket 7 with the spline form.
Hand tractor is with the operation principle of bilateral driving rotary cultivator: by the power of hand tractor output, engagement driven gear case 1 internal gear 2 by the shelves wheel rotates, give power transmission shaft 3 with power transmission, power transmission shaft rotates the drive sprocket that drives and arranged on left and right sides and rotates synchronously, 5 transmissions make the driven sprocket rotation of cutter shaft 8 and arranged on left and right sides through chain, thereby the cutter shaft rotation realizes water, the dual-purpose rotary tillage operation of dry land.Its outputting power is steady, makes the earth working quality balance.The sprocket wheel case lid adopts the little lightweight stamping parts of volume, has reduced manufacturing cost.The bilateral driving rotary cultivator of this type of hand tractor, its bilateral symmetry structure, fitting operation is convenient, high efficiency.Field work does not produce the operation moment of torsion that side driving rotary cultivator occurs.
Description of drawings
Accompanying drawing of the present utility model has:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a chain gear transmission schematic diagram of the present utility model.
Embodiment
Embodiment 1: with reference to accompanying drawing 1, Fig. 2 is an embodiment of the present utility model.The bilateral driving rotary cultivator of a kind of hand tractor, the power input shaft of tractor output shelves axle connection gear-box 1, travelling gear 2 in the casing is by the drive sprocket 4 of power transmission shaft 3 transmission bilateral symmetry configuration, drive sprocket 4 is by driving chain 5 driven transmission sprocket wheels 7, the driven sprocket 7 of balanced configuration is contained in cutter shaft 8 both sides, sprocket wheel case lid 6 is equipped with in sprocket wheel and chain outside, and the rotovator cover plate is equipped with in cutter shaft 8 outsides.This device is after power output, and the driving and driven sprocket wheel in the rotovator left and right sides rotates simultaneously to realize the rotovator synchronization job.By the power of hand tractor output, to reach dynamic balnce output, realize the effect of the steady operation of rotovator through bilateral chain Synchronous Transmission.
Above-mentioned power transmission shaft 3 both sides development length a=800mm, cutter shaft 8 operation length b=800mm.
Above-mentioned cutter shaft 8 two ends connect driven sprocket 7 with the spline form.
After the power output of hand tractor,, be converted into power transmission shaft and rotate, drive left and right drive sprocket rotation, drive left and right driven sprocket rotation through chain drive again, thereby realize that cutter shaft rotates, and implements farm work through the inner gear of the gear box transmission.
