Abstract
The utility model discloses a rotating and current mechanism with elliptic gear of a walking transplanting machine, central carrier-wheels inside of a carrier-wheels case drive a left and a right gear boxes rotate, and the left and the right gear boxes are fixedly arranged on the two sides of the central axle, a fixed center which is rotating non-uniform relative to the gear box is fixed in a satellite ellipse gear of a satellite axle via contacting and driving of a intermediate elliptic gear. Planting arms are fixedly installed at one end extending from the satellite axle, the absolute movement of the planting arms is the compound movement of the non-uniform rotating satellite of the ellipse gear relative to the gear box and the circular motion of the gear box to the central axle. The planting arms operate the rice transplanting once when the gear box orbit one circle, and adapt to the rice transplanting frequency of the walking transplanting machine when working. The path of the movement of the needle of the planting arm can be satisfied the gripping of the needle, the angle of the rice transplanting and the requirement of the path of relative motion. The curvilinear path of the relative motion of the needle is upper round and lower sharp with a tadpole shape when in working, and can guarantee the hole of the rice transplanting small with a path of an absolute movement and reduce seedling-laying rate and seedling-rinsing.
Description
Technical field
The utility model relates to agricultural machinery, especially relates to a kind of elliptic gear rotation transplanting mechanism of walk-behind type paddy-field work machine.
Background technology
At present, the rice transplanter of selling on market, its planting mechanism mainly contain two kinds: crank-rocker style transplanting mechanism and rotary transplanting mechanism.The crank-rocker style transplanting mechanism can be by changing the relative movement orbit that crank center of rotation and rocking bar oscillation center position change the seedling pawl, when its relative movement orbit is " kidney shape ", be used for saddle type rice transplanter, when its relative movement orbit is " tadpole shape ", be used for walk-behind type paddy-field work machine.The seedling pawl relative movement orbit of rotary transplanting mechanism is " straw cord for bundling up rice or wheat stalks shape ", is mainly used in saddle type rice transplanter, if when being used for walk-behind type paddy-field work machine, it is excessive that then crater is planted in rice transplanting, causes easily and float seedling and seedling laying.But rotary transplanting mechanism is compared with the crank-rocker style transplanting mechanism, has the advantage that inertia force is little, vibrate little and good stability.
Summary of the invention
The purpose of this utility model provides a kind of elliptic gear rotation transplanting mechanism of walk-behind type paddy-field work machine, and the physical dimension of this mechanism is less relatively, vibrates also little.
In order to achieve the above object, the technical solution adopted in the utility model is that it comprises drive disk assembly and transplant arm parts: described drive disk assembly is on the power transmission shaft in chain-wheel box drive sprocket to be housed, through chain be contained in chain-wheel box in center sprocket wheel on the central shaft be connected, central shaft stretches out the outer and arranged on left and right sides axle head of chain-wheel box respectively with by linking to each other with left and right gearcase by left and right flanges.On the central shaft in the described left and right gearcase, left and right central gear is housed respectively, left and right central gear is respectively by meshing with the left and right idler gear that is packed on the left and right jackshaft, by meshing with the left and right planetary gear that is packed on the left and right planet axis, the end that left and right planet axis is stretched out left and right gearcase is fixed with left and right transplant arm parts to left and right idler gear respectively.
Left and right central gear in the described left and right gearcase, the relative position triangularity in three axle center of left and right idler gear and left and right planetary gear three shaft gear planetary systems is arranged.
Described left and right central gear, left and right idler gear and left and right planetary gear are all to be elliptic gear.
Described left and right planetary gear, left and right idler gear and left and right central gear are the identical elliptic gears of gear geometric parameter.
The all positive Knucle-gear transmissions of right and wrong of the engaged transmission of described left and right planetary gear and left and right idler gear engaged transmission and left and right idler gear and left and right central gear.
Described left and right transplant arm parts are the straight arm type structure, promptly shift fork to the application point of transplanting rod with to action of cam point in the same lateral cross section of declutch shift shaft.
Respectively be fixed with a seedling pawl of being made up of the seedling pawl of two angle steel shapes on the described left and right transplant arm parts, the bottom of seedling pawl is sharp blade-like, and the inboard between two seedling pawls is level and smooth shape.
Central gear maintains static, center chain wheeling driving gear box rotates, planetary gear drives the transplant arm be packed in planet axis one end and does non-uniform rotation with respect to gearcase, and the absolute movement of transplant arm is the resultant motion around the circular motion of central shaft of the non-uniform rotation of the relative gearcase of planetary gear and gearcase.Under the influence of this resultant motion, the requirement of seedling pawl angle when seedling pawl angle and rice transplanting when the seedling pawl in the transplant arm parts satisfies seedling taking.
The beneficial effect that the utlity model has is: sun gear has only 1 group of planetary system gear drive relatively in gearcase, the relative position triangularity in three axle center of gear planetary system is arranged, drive 1 transplant arm motion, gearcase turns around, realize rice transplanting 1 cave, the rice transplanting frequency when being fit to walk-behind type paddy-field work machine work is planted the hole and is become minimum, be beneficial to upright seedling, reduce seedling rate and the seedling laying rate of floating; If improve the gearcase rotating speed, also can be used on the high-speed transplanter; The seedling pawl that adopts the seedling pin of two angle steel shapes to form, the bottom of seedling pawl is sharp blade-like, in the time of can reducing the seedling taking of seedling pawl and the frictional resistance between soil, inboard level and smooth between two seedling pawls is difficult for hindering seedling; Simple in structure, volume is little, and is in light weight, vibrate little, low cost of manufacture.
