Abstract
The utility model discloses an elliptic-circular gears backward-planting rotary transplanting mechanism of a walking transplanter. A left and a right gear boxes fixed at both ends of a central shaft are driven to rotate by a central chain wheel in a chain wheel box. In each gear box, a plenary circular gear fixed on a plenary shaft is driven by a fixed central elliptic gear through a first middle elliptic gear and a second middle circular gear both fixed on the same central shaft. A transplanting arm is fixed at one end of the plenary shaft extending out of each gear box and the absolute movement of the transplanting arm is the resultant movement of the non-uniform velocity rotation of the plenary circular gear relative to the gear box and the circular movement of the gear box relative to the central shaft. The theory of the plenary system in the mechanism is that if viewed from the side, the central shaft axis A, the middle shaft axis B and the plenary shaft axis C are arranged like a triangle. The gear boxes are rotated for one circle and the transplanting arm completes one time transplanting; the relative movement trajectory of seedling claw is similar to the dolphin-shaped curve, ensuring small transplanting hole and reducing the phenomena of seedling lying and floating. The utility model is applicable to the transplanting demands of the walking transplanter.
Description
Technical field
The utility model relates to agricultural machinery, inserts rotary transplanting mechanism after especially relating to a kind of elliptic-cylindrical gear 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 " dolphin shape ", be used for walk-behind type paddy-field work machine.The seedling pawl relative movement orbit of rotary transplanting mechanism is " kidney 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 is inserted rotary transplanting mechanism after providing a kind of elliptic-cylindrical gear 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: it comprises drive disk assembly and transplant arm parts; Drive disk assembly is included on the power transmission shaft in the chain-wheel box drive sprocket is housed, through chain be contained in chain-wheel box in center sprocket wheel on the central shaft be connected, central shaft stretches out chain-wheel box and arranged on left and right sides axle head outward and is fixed with left and right gearcase respectively.A described left side, be equipped with respectively by a left side on the central shaft in the right gear box, right flange is fixed on the left side on the chain-wheel box, right center elliptic gear, a left side, right center elliptic gear is by being packed in a left side, left side on the right jackshaft, elliptic gear in the middle of right, drive and a left side, elliptic gear and be fixed on a left side in the middle of right, left side on the right jackshaft, right intermediate cylindrical gears engaged is rotated, and a left side, right intermediate cylindrical gear be packed in a left side, left side on the right planet axis, a left side is rotated in the engagement of right lateral star roller gear, right lateral star shaft extension goes out a left side, one end of right gear box is fixed with a left side, right transplant arm parts.
The relative position triangularity in three axle center of described central shaft, left and right jackshaft and left and right planet axis three shaft gear planetary systems is arranged.
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 the seedling pawl of " U " shape on the described left and right transplant arm parts, two seedling fetching fingers that separately stretch out of seedling pawl are the angle steel shape, and the P1 place, bottom of seedling fetching finger is sharp blade-like, and the inboard P2 place between two seedlings refer to is level and smooth shape.
The center elliptic 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 (center elliptic gear) has only 1 group of planetary system gear drive relatively in gearcase, drives 1 transplant arm motion; The relative position triangularity in three axle center of gear planetary system is arranged; Gearcase turns around, and realizes rice transplanting 1 cave, the rice transplanting frequency when being fit to walk-behind type paddy-field work machine work.It is little to insert the cave, is beneficial to upright seedling, floats the seedling rate and the seedling laying rate is low; If improve the gearcase rotating speed, also can be used on the high-speed transplanter; Adopt the seedling of two angle steel shapes to refer to the seedling pawl of forming, the bottom of seedling pawl is sharp blade-like, and in the time of can reducing the seedling taking of seedling pawl and the frictional resistance between soil, inboard level and smooth between two seedlings refer to is difficult for hindering seedling; Simple in structure, volume is little, and is in light weight, vibrate little, low cost of manufacture.
