Technical background
Transplanting mechanism is the core work part of rice transplanter, and its performance determines the planting quality and efficiency of rice transplanter.At present, the form of the motor driven rice transplanter planting arm on domestic market mainly has two kinds：One kind is crank and rocker type transplanting mechanism, and another is rotary transplanting mechanism.The former is made the mechanism produce vibration when working, is influenceed rice transplanting quality due to the presence of its own design feature and pulling seedlings device.After working speed is more than 270r/min with rotating speed increase vibrate aggravate so that can not normal work, so as to limit the raising of operating efficiency.The latter such as the eccentric gear transplanting mechanism of Japan's exploitation, elliptic gear planetary system transplanting mechanism, Pascal spiral curve gear planetary transplanting mechanism and the differential type transplanting mechanism of Institutes Of Technology Of Zhejiang's exploitation, in plant revolution of arm packing list side, two planting arms are set, revolution casing rotates a circle can be with rice transplanting twice, rice transplanting linear velocity is reduced half while improving rice transplanting efficiency, greatly improve the operating efficiency of transplanting mechanism.
Multigroup non-circular gear group is respectively provided with order to meet in planting arm seedling taking action request, the plant revolution of arm case of current rotary transplanting mechanism.Multigroup non-circular gear group not only makes mechanism significantly complicated, and adds manufacturing cost and difficulty.
Chinese patent ZL98247516.0 discloses a kind of double control transplanting mechanism, is positive Knucle-gear in revolution casing, is connected by crank with rice transplanter power transmission shaft, rocking bar is connected with the sun gear in planetary gear, thus obtain meet rice transplanting requirement plant track.It has the disadvantage to use crank and rocker mechanism, have impact on the high speed performance of transplanting mechanism.Chinese patent ZL99120522.7 discloses a kind of differential transplanting mechanism, each revolution casing is using 3 elliptic gears, center elliptic gear rotates with revolution casing differential and realizes planting arm variable-speed motion, it is effectively reduced the number of non-circular gear, but the non-circular gear number of each plant revolution of arm casing will at least reach 3, therefore mechanism is complicated, and manufacturability is poor.
Utility model content
The purpose of this utility model is：The shortcoming existed for above-mentioned prior art there is provided a kind of without crank and rocker mechanism and the dual control differential planetary system transplanting mechanism of multiple non-circular gears, so as on the premise of its exercise performance is ensured, substantially reduce manufacturing cost and difficulty.
In order to achieve the above object, the technical solution adopted in the utility model is：Including with power input shaft, the static housing and the revolution casing positioned at static housing both sides of transition axis and output center axle, the cantilevered axle of the revolution casing is connected with planting arm, the power input shaft of the static housing is connected by the not rounded driving gear being fixed on transition axis and the not rounded driven gear being fixed on output center axle, the transition axis is also connected with the revolution casing drive gear outside kink in the output heart axle respectively by the active Knucle-gear at two ends, the two ends of the output center axle are respectively provided with the center Knucle-gear being located at turn around in casing, the center Knucle-gear is connected by transition gear group and cantilevered axle Knucle-gear.
Further, the both sides of the static housing dispose single-revolution casing respectively, and the end face of the revolution casing extends kink, and heart axle is outer in the output and the dental inlay tooth that is supported on static housing, and engaged by being press-fitted tooth with the end-tooth for turning round casing drive gear.
Further, the Knucle-gear of cantilevered axle of the center Knucle-gear by the transition gear groups of both sides respectively with being located at turn around tank ends is connected.
Further, active Knucle-gear and the gear ratio of revolution casing drive gear are 1：2.
After the utility model, theory and practice is proved, the movement locus of planting arm can meet plant requirement completely, due to being entirely the differential gear train of positive round gear composition in revolution case, only one is pointed to the central gear in the non-circular gear control left and right revolution case in static housing, therefore manufacturing cost and difficulty are greatly reduced, and the reduction of non-circular gear also significantly reduces the vibration produced in transmission process.
