The utility model has the advantages of compact structure, compactness, flexibility, convenient operation, low labor intensity and high productivity.

Description

Original place full circle swinging mini-size tillage machine

The utility model relates to a kind of agricultural tillage machinery, especially original place full circle swinging mini-size tillage machine.

At present, though the agricultural tillage of domestic use machinery is a lot, all can not carry out original place full circle swinging campaign.The turning that has is to realize the turning an of part (or long radius) by pulling manipulating handgrip, has plenty of by people's muscle power pulling rotary tillage cutter hub and finishes turning, and what also have then is by one of two people rotovator to be lifted turning.Aforementioned these several turning modes were both taken time, and took muscle power again, used extremely inconvenience, simultaneously, had also influenced production efficiency.

The purpose of this utility model provides a kind of original place full circle swinging mini-size tillage machine, by changing the reduction box structure of former tiller, solves the curved problem of original place full circle swinging of agricultural tillage machine.

Concrete scheme of the present utility model is: a kind of original place full circle swinging mini-size tillage machine, form by oily machine, handle, reduction box, safty shield, rotary tillage cutter hub, it is characterized in that: reduction box not only comprises belt wheel, power shaft, clutch, clutch shifter, gear, power transmission shaft, travelling gear, driven gear, shell and bearing block, and left-hand bend mechanism and right-hand bend mechanism also are housed in the enclosure; This left-hand bend mechanism and right-hand bend mechanism are meant right output shaft and left output shaft and two minor axises that splined shaft are housed, linked to each other by middle bearing bracket in the reduction box shell; Spring and ball are housed in splined shaft, outside splined shaft, are set with the bidentate wheel; Be equipped with at the two ends of left output shaft that gear is advanced on a left side and a left side goes out gear, be equipped with at the two ends of right output shaft that gear is advanced on the right side and the right side goes out gear; Transition gear is housed respectively on two minor axises, gear is moved back on a left side or gear is moved back on the right side.

Adopt the such scheme compact conformation, small and exquisite flexible, handiness, labour intensity is low, can realize original place full circle swinging turning, the productivity ratio height.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the structural representation of reduction box among Fig. 1;

Fig. 4 is the A-A cutaway view of Fig. 3.

The number in the figure meaning is: 1 belt wheel, 2 power shafts, 3 clutches, 4 clutch shifters, 5 tooth axles, 6 power transmission shafts, 7 travelling gears, 8 driven gears, 9 springs, 10 balls, 11 Double-gears, 12 splined shafts, 13 Double-gears, 14 right sides are entered gear 15 right sides and are gone out gear 16 right axles 17 left sides and enter gear 18 left axles 19 left sides and go out gear 20 left sides and move back gear 21 transition gears 22 middle bearing brackets 23 right sides and move back gear 24 transition gears 25 minor axises 26 gear shifter yokes 27 shells 28 oil machines 29 handles 30 reduction boxes 31 safty shields 32 rotary tillage cutter hubs

As shown in Figure 1 and Figure 2: the utility model mainly is made up of oily machine 28, handle 29, reduction box 30, safty shield 31, rotary tillage cutter hub 32, it is characterized in that: reduction box 30 not only comprises belt wheel 1, power shaft 2, clutch 3, clutch shifter 4, tooth axle 5, power transmission shaft 6, travelling gear 7, driven gear 8, casing 27 and bearing block, and left-hand bend mechanism and right-hand bend mechanism also are housed in shell 27.

As shown in Figure 3, Figure 4: the left-hand bend mechanism in the shell 27 and right-hand bend mechanism are meant right output shaft 16 and left output shaft 18 and two minor axises 25 that splined shaft 12 are housed, linked to each other by middle bearing bracket 22 in reduction box shell 27; Spring 9 and ball 10 are housed in splined shaft 12, outside splined shaft 12, are set with bidentate wheel 11,13; Be equipped with at the two ends of left output shaft 18 that gear 17 is advanced on a left side and a left side goes out gear 19, be equipped with at the two ends of right output shaft 16 that gear 14 is advanced on the right side and the right side goes out gear 15;

Transition gear

21,24 is housed respectively on two minor axises 25, and gear 20 is moved back on a left side or gear 23 is moved back on the right side.

Also can further see from Fig. 4: the ball 10 in the splined shaft 12 is positioned at two of spring 9; Gear shifter yoke 26 is equipped with in the bidentate wheel 11 of splined shaft 12 outer suits and the centre of bidentate wheel 13.

The utility model is performed such work: oily machine 28 drives power shaft 2 and rotates, driving tooth axle 5 during clutch 3 engagements rotates, tooth axle 5 drives driven gear 8 by travelling gear 7 and rotates, and driven gear 8 drives splined shaft 12 and rotates, and the bidentate wheel 13 and 11 on the splined shaft 12 rotates; When advancing: bidentate wheel 11 advances gear 14 engagements with the right side, and bidentate wheel 13 advances gear 17 engagements with a left side, and right axle 16 and left side axle 18 drive 32 rotations of rotary tillage cutter hub respectively; When retreating: bidentate wheel 11 advances gear 14 with the right side and throws off, this moment, bidentate wheel 11 moved back gear 23 engagements with the right side, coaxial continuous transition gear 24 goes out gear 15 engagements with the right side, and bidentate wheel 13 enters gear 17 disengagement backs with a left side and moves back gear 20 engagements with a left side, and transition gear 21 goes out gear 19 with a left side and meshes; When turning left: bidentate wheel 13 advances gear 17 engagements with a left side, and bidentate wheel 11 moves back gear 23 engagements with the right side, and transition gear 24 goes out gear 15 engagements with the right side; When turning right: bidentate wheel 11 advances gear 14 engagements with the right side, and bidentate wheel 13 moves back gear 20 engagements with a left side, and transition gear 21 goes out gear 19 engagements with a left side.
