Abstract
The present invention discloses a planetary system transplanting mechanism with cylindrical teeth and elliptic teeth. A central chain wheel in a chain wheel box drives a left gear case and a right gear case to rotate, and a central cylindrical gear in the gear case is immobilized; two cylindrical tooth planetary wheels which are engaged with the central cylindrical gear rotate with the gear cases so as to drive a coaxial elliptic gear to rotate, and the elliptic gear is engaged with a planetary elliptic gear so that the elliptic gear rotates in a non-uniform velocity relative to the gear cases. The absolute motion of a pair of transplanting arms which are fixedly connected with the planetary elliptic gear is the composition of the circular motion of the gear cases and the non-uniform velocity rotation of the planetary elliptic gear. The present invention reduces distance between a planetary wheel shaft and a central axis, decreases the length of the radius of gyration and reduces inertia force. The gear cases which are in a circular disk form have small shock to seedlings, so damage to seedlings can be reduced. The present invention has the advantages of reasonable structure and selection of proper structure parameters, and traces of the seedling transplantation of the transplanting arms satisfy operating requirements for rice seedling transplantation.
Description
Technical field
The present invention relates to the planting mechanism of paddy rice power rice-transplantor, is the oval tooth planetary system of a kind of cylinder tooth transplanting mechanism.
Background technology
At present, the paddy rice power rice-transplantor of selling on the market at home, the form of its planting mechanism has two kinds: a kind of is crank rod-type transplanting mechanism, another kind is the rotation transplanting mechanism.The former operating frequency energy operate as normal in the time of 200～220 times/minute along with the increase of rice transplanter frequency, can make the aggravation of rice transplanter frame vibration; Simultaneously planting mechanism seedling needlework speed is too high, can produce the inequality of separating seedlings or planting, damaged seedling rate and leak that the seedling rate increases and defectives such as transplant arm rapid wear, thus limited the raising of operating efficiency.What the latter such as Japan developed is eccentric gear and elliptic gear mechanism, referring to " mechanization of rural area, Jilin " 1991 (5) pages the 35th page and " modernization agricultural " 1995 (11) the 29th～31 pages, two transplant arms are set on gearcase, rice transplanting is twice but gearcase rotates a circle, improved rice transplanting efficient, reduced seedling needlework speed, so damaged seedling rate has been low, the precision of separating seedlings or planting height, the rice transplanting quality is good.But Japan is single cropping rice country, and its transplanting mechanism mainly is applicable to the seedling operation (early rice rice transplanting) of rice seedling, referring to " 1990 (5) the 7th～10 pages of agriculture and animal husbandry and food machinerys; China's southern area the double cropping rice of planting can only be inserted a season, so its scope of application reduces greatly.
Summary of the invention
The purpose of this invention is to provide a kind of mechanism compactness, hinder that seedling is little, the oval tooth planetary system of the simple cylinder tooth of little, the manufacturing process of vibration transplanting mechanism.
In order to achieve the above object, the technical solution used in the present invention is:
It comprises drive disk assembly and transplant arm parts, drive disk assembly is included on the interior power transmission shaft of chain-wheel box drive sprocket is housed, be connected with center sprocket wheel on being contained in central shaft through chain, the outer left and right sides of chain-wheel box is equipped with gearcase respectively, the both sides of the central shaft in the gearcase are equipped with central gear respectively, rotate with spline driven gear box respectively at the two ends of central shaft, the central gear at two ends is fixed on the chain-wheel box by flange respectively, the both sides of the central gear in the gearcase of the left and right sides, the intermediate cylindrical gear is housed respectively successively symmetrically, coaxial respectively two gears that are equipped with of two intermediate cylindrical gears in the left gear box, two gears of left side on the jackshaft are meshed with planetary gear on separately the planet wheel spindle respectively, coaxial respectively two gears that are equipped with of two intermediate cylindrical gears in the right gear box, two gears on the jackshaft of right side are meshed with planetary gear on separately the planet wheel spindle respectively; Planet wheel spindle in two gearcases all stretches out an end of left and right sides gearcase, is connected with spline with separately transplant arm parts respectively.The central gear that be equipped with respectively the both sides of described central shaft is the centered cylinder gear; Planetary gear on described two groups of planet wheel spindles is two groups of planet elliptic gears; Two elliptic gear transmissions on two gears on the jackshaft of described left side and the planet wheel spindle are the elliptic gear transmission; Two elliptic gear transmissions on two gears on the jackshaft of described right side and the planet wheel spindle are the elliptic gear transmission; Two groups of gears on the jackshaft of described both sides respectively with central shaft on two gear drives be column gear transmission.
The center of rotation of gearcase is not on the line of a pair of planet elliptic gear and elliptic gear center of rotation.The number of teeth of elliptic gear, modulus, major axis and minor axis are all identical.The transplant arm parts are eccentric bent-arm structure in a side, and cam planes, transplanting rod central plane are vertical with the gearcase center of rotation, not at grade.
Said transplant arm parts: a kind of is that the transplanting rod application point of shift fork is with respect to cam application point skew～distance; Another kind is a seedling pin parallel offset transplanting rod slideway.
The centered cylinder gear maintains static, and center chain wheeling driving gear box rotates, and the planet elliptic gear is done non-uniform rotation with respect to gearcase, and its absolute movement is around central shaft circular motion and synthesizing around the non-uniform rotation of gearcase.Under the influence of this resultant motion, the requirement of seedling pin angle when seedling pin angle and rice transplanting when the seedling pin in the transplant arm parts satisfies seedling taking, its work track latch closure, highly less, the seedling pin moves up backward after the rice transplanting, avoids pushing over rice shoot and bumps seedling shoving rod.
The present invention compared with prior art, the useful effect that has is:
1) because planet wheel spindle, can be reduced to the central shaft distance not point-blank in three axle center of the center of rotation of gearcase, planet elliptic gear, elliptic gear, reduces the turning radius, reduced inertia force;
2) gearcase adopts disc type little to the impact of rice shoot, can lower and hinder seedling;
3) gearcase adopts disc type, and rational in infrastructure, intensity is big, bears big load, the O-ring side face, and machining accuracy guarantees easily, good seal performance.Select suitable structural parameters, the seedling pin track of transplant arm satisfies the job requirement of rice transplanting.
