Abstract
The utility model discloses a furrow-compacting seeding machine belonging to agricultural machinery, which is composed of four-rod feeler mechanism, furrow-compacting wheel mechanism, seeding mechanism, and soil covering mechanism connected by connecting triangle and connecting beam. Before seeding, the furrow-compacting wheel firstly compacts seed bed, which is favorable for storing water and improving soil moisture content; seeds are then sowed on the compacted seed bed; and finally the soil covering mechanism compacts and levels the soil to keep soil moisture. For crops such as corn and soybean planted in dry farmland in North China, the utility model is very effective for improving soil moisture content, seed survival rate, and crop output.
Description
One, technical field
The utility model belongs to agricultural machinery.
Two, background technology
Because kind ground in spring meets vast the Northeast in China when dry land ridge culture crops such as maize planting, soybean at present, but the spring soil soil moisture content of often hitting by drought 9 years out of 10 is bad, when planting ground, various forms of ploughs are left a zanjon about wide 50-200mm with the soil, sower is sowed in ditch then, seed is broadcast on soft soil, the very fast evaporation of moisture content in the soft soil property, influence the moisture content of soil, cause the seed after seed can not germinate or germinate to can not get follow-up moisture, bud taking place do phenomenon, directly influences the number of keeping a full stand of seedings.As the saying goes: " the rich kind of buying, no money is bought seedling." vast farmers is in the epoch on traditional use ox and horse kind ground, and a kind of saying of bottom sieve frame of stepping on arranged, promptly tramp with one's feet at the bottom of trench of leaving ditch, and then sowing, earth backing is finished the sowing process.
Nowadays, be that the sowing custom of power is fewer and feweri with ox and horse, what replace it is to be the seeding method of power with tractor, this has become the main flow in vast rural area, northeast.Though the sower of multiple pattern is arranged in existing seeding technique, but also do not have this so far: leave loosen the soil on press earlier ditch, cause solid kind bed, make soil form tiny capillary, after planting the soil below the seed is raised to moisture content around the seed according to principle capillaceous, reach the effect of putting forward moisture in the soil, after planting reach the soil moisture conservation purpose through the suppression earth backing again.
The utility model is exactly to overcome existing traditional kind method for planting, presses the planting technology of sowing behind the ditch to obtain the more land measure equal to fifteen mu in most parts of the Northeast number of keeping a full stand of seedings earlier thereby adopt, and improves the purpose of crop yield.
Three, summary of the invention
The purpose of this utility model provides a kind of pressure ditch sower, improves the operation quality of existing sower, and can be implemented in agricultural production.
The utility model is made up of four bar feeler mechanisms, groove pressing wheel structure, seeding unit mechanism, suppression earth backing mechanism.By connecting triangle, connect crossbeam, these several parts are connected together.Kind of when ground, press the ditch sower to be articulated on the tractor by four bar feeler mechanisms, can unscrew, rake or open in the soil of ditch and advance; Four connecting rods are to guarantee to press the ditch sower to contact with ground at any time in the process of advancing, and can play the profiling effect like this; Adjust compression spring and can increase or reduce the pressure of pressure ditch sower ground; Depth control shoe is to prevent to press the ditch sower liftoff too near when hanging transportation, causes current difficulty.The groove pressing wheel structure is by groove pressing wheel and press dark adjuster to form.Groove pressing wheel adopts rubber wheel to make the minimizing clay; Pressing dark adjuster is the pressure trench depth that is used for regulating groove pressing wheel.The seeding unit structure is made up of kind of a case, seeding unit, ship shape seed-pretecter.Plant the interior seed of case by seeding unit, under the protection of ship shape seed-pretecter, seed is broadcast and is executed by on the kind bed of groove pressing wheel compacting.Suppression earth backing structure is made up of disk extruding press wheel, press wheel pressurizer, clean-up scraper.Disk extruding press wheel can be expressed to soil above the seed and with the soil compacting; The press wheel pressurizer can change the backfill consolidation degree; Soil scrapper then is that the soil on multiple after the compacting of seedling band is further wipeed off, reaches the purpose of soil shaping.
