Description

The paddy rice planter

The utility model belongs to the agricultural machinery class, particularly a kind of agricultural thing planter.

Rice cropping changes program request into by transplanting to have such as raising the efficiency, save advantages such as seed, shortening rice growing season.Its traditional planting type such as some dry crops such as wheat, soybean, peanut, jute also is program request.Therefore, the appearance of planter give agricultural production progressively mechanization a basis is provided.The planter that uses all is made up of institutes such as anti-pulley, frame and seeders at present.This class planter is compared with artificial directly sowing, has the saving manpower, saves seed, improves advantages such as work efficiency.But there is defective on the existing model structure, function singleness (often a kind of type only adapts to a kind of crop), seed breakage rate and cave leakage sowing rate are all high, the line-spacing spacing in the rows is difficult to adjust even can't adjust, it is narrow to broadcast a number adjustable extent under the seed of cave, and it is strict that seed is broadcast preceding vernalization, and dependability is poor.

The purpose of this utility model is developed a kind of wide adaptability exactly, and is multiple functional, the crops planter of dependable performance.

Following technical proposals just can realize the purpose of the utility model defined: planter is made up of frame, anti-pulley and seeder.Seeder is made monomer-type, and the frame sowing axle that string dress is fixed on horizontal device is gone up and made the distance between the seeder adjustable.There is formation plate in seeder the place ahead, and there is lid kind of device the back.Seeder is by the synthetic D shape of circular distribution plate and bowl-type block, and enclosure space therebetween forms the kinds of bank deposits jar, and the bowl-type side of blocking a shot has and adds kind of a mouth.The radiation upper edge dish edge of angles such as circular distribution plate outer surface is evenly equipped with and distributes bucket, and distributing the bucket outer end is sowing opening; Circular distribution plate inner surface distributes the place of bucket to have into kind of a mouth corresponding to each.In the trapezoidal distribution bucket partition is arranged, make and distribute the bucket inner chamber to form a U-shaped passage.Circular trimmer also is housed on the distribution plate inner surface, sawtooth projection is arranged and can cover kind of mouth to some extent along with the rotation of trimmer corresponding to distributing bucket to go into kind of mouth on it to change the size of going into kind of mouth.Go into kind of mouth and seed can be entered smoothly to distribute bucket in order to ensure minimum, be provided with damping fin at an edge of going into kind of mouth.On the frame corresponding to the seeder direction of advance arc-shaped spring piece is housed, distribution bucket sowing opening on this side is covered the sowing axle directly or by transmission mechanism order about rotation: the two ends of the rack-mounted respectively sowing axle of anti-pulley by anti-pulley, directly be with relay kind of an axle and a seeder by anti-pulley in advancing, this type is single-shaft variant; Driving shaft is installed on frame, unidirectional driving gear is housed in the middle of it, the sowing axle is gone up corresponding place multistage driven gear is housed, and driving gear is connected with driven gear by driving-chain, regulating wheel is arranged the driving-chain tensioning in the middle of the driving-chain, anti-pulley is installed in the two ends of driving shaft respectively, and anti-pulley is relayed kind of an axle and a seeder by driving shaft, gear and transmission chain belt, and this type is biaxial type.Also be equipped with on the frame of two kinds of types and carry machine handle and draw bar.The operation principle of the utility model planter is such: planter travels forward under the manpower traction, anti-pulley is (single-shaft variant) or drive seeder by transmission mechanism (biaxial type) and rotate directly, seed in the kinds of bank deposits jar and circular distribution plate do relative motion because the seeder block is bowl-type, kinds of bank deposits jar inwall all tilts to distribution plate, and therefore a jar interior seed is all drawn close toward the distribution plate aspect.Go into kind of a mouth when forwarding to when what distribute bucket with the seed position contacting, seed self extruding force and the damping action of damping fin under enter and distribute bucket by going into kind of a mouth.Continue to rise along with the rotation of seeder distributes bucket, descend again, seed in distributing bucket the edge along the U-shaped passage slide into sowing opening, but when distributing bucket to begin to descend its sowing opening entered arc-shaped spring piece and covered firmly, seed can't broadcast.Have only when sowing opening to drop to minimum point and during over against ground, sowing opening just in time leaves arc-shaped spring piece and is opened, seed is fallen on the ground immediately, covers on seed immediately following just mud or earth being dragged at the lid kind device of seeder back.When distributing bucket to descend and gathering before the seed of sowing opening broadcasts as yet, going into kind of mouth has new seed to enter again to distribute bucket, but because new seed does not also slide into sowing opening along the U-shaped passage, so when sowing opening during over against ground, the seed that newly enters can not broadcasted yet.The formation plate of seeder front can flatten tractor's footprint cave prior to seeding.The utility model planter also can adopt animal power or mechanical traction, and sowing this moment axle can suitably extend, and the seeder quantity on it can suitably increase.

The utility model planter novel structure, dependable performance is operated simple and easyly, easy to maintenance, applied widely, and the nonirrigated farmland, paddy field all can be used; Be mainly used in the paddy rice program request, also can be used for crop sowings such as wheat, soybean, peanut, corn, jute; But both program requests can be carried out drilling again after uncovering arc-shaped spring piece.Less demanding to broadcasting preceding presprouting of seeds (as vernalization length).The seed phenomenon that has no mechanical damage in the sowing process.Can change the line-spacing and the spacing in the rows of sowing: promptly change the adjustable full line distance of distance (generally between 18-24 centimetre, adjusting) between last two seeders of sowing axle; The adjustment of spacing in the rows, single-shaft variant planter realize that by the anti-pulley of changing different-diameter the rank that the biaxial type planter then only needs to select driven gear gets final product (generally dividing three grades of adjustment in the 9-15 cm range).How much distribute bucket to go into kind of mouth can according to the difference of crop seed and regulating by circular trimmer of every bunch planting kind number, and for example hybrid rice can be transferred to every cave 2-3 grain, conventional rice 4-5 grain.The utility model planter also has leakage sowing rate low (less than 5%), program request falls to planting a poly-cavitation, and row is broadcast evenly to spread and embarked on journey production efficiency height (per hour can broadcast 2-2.5 mu), save seed advantages such as (hybrid rice are used the 1.25-1.5 kilogram for every mu, every mu of 2.5-3 kilogram of conventional rice).Single-shaft variant planter low price, the biaxial type planter is easy to adjust, all can operation on flat field, hillside, big and small field piece, real is the standing agriculture apparatus of farmers'.
