Abstract
The utility model discloses a kind of ellipse-ellipse pitch curve gear planetary system type rotary transplanting mechanism, it mainly comprises sun gear, two breast wheels, two planetary gears, planet carrier, two transplant arms, two seedling pins and frames; Seedling is hindered few during the gearratio rice transplanting of the utility model transplanting mechanism travelling gear; The pitch curve of sun gear waits the elliptic arc curve of major axis, the minor axis such as not to form by two sections, two kinds of line smoothings connect, and respectively occupy the central angle of 180 °, make seedling pin not hinder seedling when seedling taking by the minor axis adjusting two sections of elliptic arcs, when pushing away seedling, cave is young, not easily produces drift seedling and seedling laying phenomenon.
Description
Technical field
The utility model relates to a kind of high-speed rice seedling planter, particularly relates to a kind of ellipse-ellipse pitch curve gear planetary system type rotary transplanting mechanism.
Background technology
High-speed rice seedling planter rotary transplanting mechanism has the advantages such as rice transplanting speed is fast, production efficiency is high, favorable working performance.But the non-circular gear system drive characteristic of the rotary transplanting mechanism of design is at present not so good, the vibration of machine is comparatively large, poor to the adaptability of transplanting rice shoot size.As: the movement locus of the existing non-circular gear transplanting mechanism be made up of a kind of oval knot curve and attitude are relatively more serious in the damage of rice shoot seedling taking at present, and the transplanting cave mouth produced after pushing away seedling transplanting is also comparatively large, easily causes seedling laying and drift seedling phenomenon.So, a kind of novel non-circular gear pitch curve planetary system type separate transplanting mechanism be designed.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of ellipse-ellipse pitch curve gear planetary system type rotary transplanting mechanism.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of ellipse-ellipse pitch curve gear planetary system type rotary box of transplanting mechanism, and it mainly comprises sun gear, two breast wheels, two planetary gears, planet carrier, two transplant arms, two seedling pins, frames; Sun gear is fixedly connected in frame, and planet carrier is arranged in frame; Sun gear both sides are symmetrical, are furnished with breast wheel and planetary gear all successively; And the pivot of two breast wheels and two planetary gears is fixed on planet carrier, two transplant arms are fixedly connected on two planetary gears respectively, and two seedling pins are fixedly connected on the front portion of two transplant arms respectively; Breast wheel respectively with sun gear and planetary gear conjugation, breast wheel and sun gear engagement, engage with planetary gear again simultaneously; The pitch curve of sun gear waits the elliptic arc curve A CB of major axis, the minor axis such as not and elliptic arc curve A DB to form by two sections, and two kinds of line smoothings connect, and respectively occupy the central angle of 180 °.
The utility model patent compared with prior art, the beneficial effect had is: non-circular gear pitch curve adopts two sections of semiellipse compositions waiting major axis not wait minor axis, pitch curve change flexibly, thus the transplanting cave mouth produced after making to push away seedling transplanting is less, seedling laying and the drift seedling phenomenon of transplanting rice shoot obviously reduce, hinder seedling few, multiple agriculture requirement can be met.
Accompanying drawing explanation
Fig. 1 is mechanism principle sketch of the present utility model;
Fig. 2 is gear pitch curve pie graph of the present utility model;
In figure: sun gear 1, breast wheel 2, planetary gear 3, planet carrier 4, transplant arm 5, seedling pin 6, frame 7, elliptic arc curve A CB8, elliptic arc curve A DB9.
Embodiment
Below in conjunction with accompanying drawing, the utility model patent is further described.
As shown in Figure 1, a kind of ellipse-ellipse pitch curve gear planetary system type rotary transplanting mechanism, it mainly comprises sun gear 1, two breast wheels 2, two planetary gears 3, planet carrier 4, two transplant arms 5, two seedling pins 6, frames 7; Sun gear 1 is fixedly connected in frame 7, and planet carrier 4 is arranged in frame 7; Sun gear 1 both sides are symmetrical, are furnished with breast wheel 2 and planetary gear 3 all successively; And the pivot of two breast wheels 2 and two planetary gears 3 is fixed on planet carrier 4, two transplant arms 5 are fixedly connected on two planetary gears 3 respectively, and two seedling pins 6 are fixedly connected on the front portion of two transplant arms 5 respectively; Breast wheel 2 respectively with sun gear 1 and planetary gear 3 conjugation, breast wheel 2 and sun gear 1 engage, and engage with planetary gear 3 again simultaneously; When planet carrier 4 is around the center of rotation O of sun gear 1
1during uniform rotation, planetary gear 3 with planet carrier 4 also around O
1uniform rotation; Relative to planet carrier 4, under the effect of sun gear 1 and breast wheel 2, breast wheel 2 and planetary gear 3 two pairs of noncircular gear pairs, planetary gear 3 is around O
3non-uniform rotation.So the motion of planetary gear 3 is by around O
1uniform rotation and around O
3non-uniform rotation is composited, and the transplant arm 5 be connected with planetary gear 3 and the motion of seedling pin 6 are also compound motions, thus forms rice transplanting track and the rice transplanting attitude that can meet agriculture requirement.In addition pitch curve change diversity there has also been and significantly improves, and the transplanting cave mouth produced after making to push away seedling transplanting is less, and seedling laying and the drift seedling phenomenon of transplanting rice shoot obviously reduce, and it is few to hinder seedling.
As shown in Figure 2, the pitch curve of sun gear 1 waits the elliptic arc curve A CB8 of major axis, the minor axis such as not and elliptic arc curve A DB9 to form by two sections, and two kinds of line smoothings connect, and respectively occupy the central angle of 180 °.
Now ellipse-ellipse pitch curve gear planetary system type rotary transplanting mechanism and oval knot curved tooth cylindrical gear planetary system rotary transplanting mechanism are applied to high-speed transplanter, and carry out field comparison test.Test site is Xiaoshan Taurus agricultural machinery cooperation, and the area in test plot is 30m
2, the broken Tian Ping of mud, mud pin degree of depth 150mm, adopt seedling-cultivation plate, and dish soil is not loose, and seedling dials is tied, and rice shoot average height is 150mm, leaf age 3 ~ 4, and seedling dish width is 300mm, the thick 19 ~ 21mm of soil layer, soil moisture content 50%.Experimental Comparison result is as shown in table 1.
Table 1 field comparison test result
| Parameter | Technical requirement | Transplanting mechanism of the present invention | Oval knot curved tooth cylindrical gear transplanting mechanism |
| Seedling laying rate/% | ≤3 | 2.1 | 2.8 |
| Drift seedling rate/% | ≤3 | 1.7 | 2.6 |
| Damaged seedling rate/% | ≤4 | 2.1 | 3.6 |
This test contrasts for seedling laying rate, drift seedling rate and damaged seedling rate, two kinds of transplanting mechanism result of the tests can both meet basic technical requirement, but transplanting mechanism of the present invention is when rice transplanting is tested, seedling laying rate is 2.1%, drift seedling rate 1.7%, damaged seedling rate 2.1% all will lower than oval knot curved tooth cylindrical gear transplanting mechanism.
