Description
Technical field
The utility model relates to a kind of rice transplanter, especially relates to a kind of rice transplanting mechanism of rice transplanter.
Background technology
Traditional rice cropping generally all adopts etc. line-spacing, etc. the transplanting method of spacing in the rows, still will inevitably occur the problem of sunshade between this transplanting method plant and the plant, and inhomogeneous, thereby cause very big waste utilizing of the nutrient in the earth.Afterwards, people had invented the capable rice cultivating method of a kind of width, a kind of high-yielding rice cultivation technique that to be the narrow row distance cultivate with wide line-spacing at interval.The cave number of this planting type on can guarantor unit's area is reasonable, and it is reasonable to have the plant population distribution again, and the ventilation and penetrating light performance is good, the photosynthetic rate advantages of higher, so unit yield is higher, is one of normal planting type of selecting of high yield tackling key problem.Simultaneously,, can alleviate the harm of disease worm to a certain extent, finally reach the purpose that high yield increases income because the enhancing of ventilation and penetrating light property makes humidity reduction between the rice strain.But the cultivation spacing of wide-and narrow-row rice culture technique is different, and it is more inhomogeneous to the nutrien utilization in the earth, and solar irradiation also has a big chunk to be blocked each other by plant.Therefore people have invented measurements of the chest, waist and hips intensified culturing technology on this basis again.In measurements of the chest, waist and hips intensified culturing technology, constitute triangle distribution (preferred isosceles triangle distributes) light between plant and come can not block mutually from which face, improved the intake of rice shoot greatly to sunlight, increased photosynthesis.One group of per two behavior of measurements of the chest, waist and hips intensified culturing technology, every component is furnished with several triangle plant, and the spacing of each plant in the triangle plant is identical, makes plant very even to nutrient absorbing in the earth, has farthest utilized soil fertility.This culture technique makes that under the cultivation condition of equal densities, the spacing of each plant has arrived maximization greatly simultaneously, helps ventilating, and has reduced damage by disease and insect.But therefore the rice transplanting machinery that also is not suitable for measurements of the chest, waist and hips intensified culturing technology at present, generally can only be accomplished through rice transplantation by hand, limited the popularization of measurements of the chest, waist and hips intensified culturing technology greatly.
Existing rice transplanter generally all comprises the rice transplanting driving box; The both sides of rice transplanting driving box are respectively equipped with the revolution case, and the revolution case is provided with former and later two transplanting arms, and revolution case and transplanting arm are driven by the rice transplanting driving box; The power of rice transplanting driving box is provided through transmission mechanism by the rice transplanting locomotive; In general, be provided with sprocket wheel, chain in this rice transplanting driving box, and the output shaft that links to each other with described revolution case.Like publication number is the transplanting mechanism that the Chinese patent of CN102342205 discloses a kind of rice transplanter, comprises transplanting case, revolution case and transplanting pawl, and the moving axis output shaft of described transplanting case links to each other with the rotating shaft of a sun gear in being located at the revolution case; The end of transplanting pawl is provided with outer pawl head; Should comprise that two pawls referred to by outer pawl head, described pawl arm is provided with interior pawl, and interior pawl and pawl arm are slidingly connected; And be provided with one make in the elastic recovery mechanism that moves upward of pawl; The pawl head of interior pawl is that single pawl refers to, between two pawls that the root that interior pawl pawl refers to is located at outer pawl referred to, the upper end of interior pawl and a driving rod were rotationally connected; This driving rod and pawl arm are rotationally connected, and match with a cam on the wheel shaft of being located at second planetary gear.The power of the rice transplanter of this structure need be through the transmission of frame for movement; Obtain from the rice transplanting locomotive; And the motion of rice transplanting mechanism need keep certain comparison with the speed of a motor vehicle, and guaranteeing suitable seedling planting row pitch, so the structure more complicated, required precision is high, cost is high, the maintenance trouble.
