Abstract
The invention discloses a transplanting mechanism of a gear driving oblique wide and narrow row rice transplanter. Both sides of a chain wheel shaft are respectively provided with a transmission box and a transplanting arm with the same structure; the transmission box has the structure that a driving gear is fixed on the end of the chain wheel shaft; the driving gear is meshed with a driven gear fixed on an output shaft; the output shaft and the chain wheel shaft are arranged obliquely in a crossed way; the end of the output shaft is fixedly connected with a planet carrier; a sun gear supported on the output shaft by a bearing is fixedly connected with the end of the chain wheel box by a flange in the planet carrier; the sun gear is respectively connected with respective planet wheels by a middle wheel; and a planet wheel shaft fixedly connected with a right planet wheel is respectively connected respective right transplanting arms. Seedling needles on the transplanting arms driven by the planet wheels move in an oblique plane; after the seedling needles are used for taking seedlings, lateral motion relative to an advance direction is generated due to the obliqueness of the planet carrier so that the transplanting points of the seedlings move leftwards or rightwards relative to seedling taking positions; on the premise that seedling taking ports are distributed at the same interval, the seedling transplanting positions are distributed in wide and narrow different row distances required by agriculture.
Description
Technical field
The present invention relates to the rice transplanter transplanting mechanism, relate in particular to a kind of transplanting mechanism of gear driving oblique wide and narrow row seedling transplanter.
Background technology
The capable rice transplanting of width is carried out one wide one narrow planting patterns with regard to the line space that is meant rice transplanting, this planting patterns is utilized the volume increase principle of crop limit advantage, by adjusting the line space of rice transplanting, improve ventilation, light transmittance between plant, alleviate disease, increase leaf area index, prolong leaf longevity, quicken dry-matter accumulation, thereby reach the purpose of good quality and high output, cost-saving synergistic.
Transplanting mechanism is to realize seedling taking on the rice transplanter, implant Tanaka, make the parts of rice shoot succeeding planting.In existing disclosed rice transplanter transplanting mechanism document, sun gear central shaft and sprocket shaft on the existing transplanting mechanism are coaxial, planet carrier is vertical with sprocket shaft, the seedling pin moves in the plane perpendicular to sprocket shaft and ground on the transplant arm, under seedling fetching hole was equally spaced prerequisite, the capable rice shoot of width that the rice transplanting position can not form agriculture requirement distributed.
Summary of the invention
The object of the present invention is to provide a kind of planet circular system transplanting mechanism that can realize the capable rice transplanting operation of width.
In order to achieve the above object, the technical solution used in the present invention is:
Power is delivered to second sprocket wheel by first sprocket wheel by chain, and second sprocket wheel is cemented on the sprocket shaft, at the identical left and right transmission case of sprocket shaft both sides difference mounting structure, is contained in the transplant arm of left and right transmission case body upper and lower sides; Right transmission case structure is the fixing right driving gear of sprocket shaft right-hand member, with the right driven gear engagement of being fixed on the right output shaft, right output shaft and sprocket shaft inclination interlaced arrangement, the right-hand member and the right planet carrier of right output shaft are affixed, in right planet carrier, fixedly connected with the right-hand member of chain-wheel box by right flange by the right central gear of bearings on right output shaft, right central gear is connected with separately upper and lower right lateral star-wheel respectively through upper and lower right breast wheel, is connected separately upper and lower right transplant arm respectively with the fixedly connected upper and lower right lateral spider gear shaft of upper and lower right lateral star-wheel.
Described right driving gear and right driven gear are helical gear or bevel gear.
Described right planet carrier and sprocket shaft are in tilted layout, making has the angle of inclination between the working face of transplanting mechanism seedling pin and the sprocket shaft, this angle of inclination make the seedling pin relative seedling taking position, rice transplanting position to the right offset distance from δ, to realize wide row, narrow row change line-spacing rice transplanting spaced apart.
Slotted hole, locating hole that circumferencial direction is a waist shape are set on the described right flange, rotate right flange by aiming at different locating holes, the azimuth of the right central gear major axis of energy minor alteration.
