Abstract
The invention relates to a transplanting mechanism of a helical-tooth staggered shaft deformed ellipse gear wide and narrow row high-speed transplanter, and belongs to the agricultural machinery. According to the transplanting mechanism, five deformed ellipse gear planetary gear system are adopted as variable speed transmission mechanisms, wherein the sun gear is the deformed ellipse skew gear, the other gears are the spur gears; middle gear shafts and a sun gear shaft form staggered angles; planetary gear shafts are parallel to the middle gear shafts; a planting arm and the planetary gear shafts are vertically and fixedly arranged. According to the present invention, the transmission ratio curve of the gear transmission is changed by adjusting the deformation coefficient of the deformed ellipse gear, such that the utilization rate of the lateral drift generated by the staggered shaft is improved, the invalid lateral drift is reduced, the wide and narrow row transplanting required by the agronomy is obtained at the minimum helix angle so as to avoid the influence on the upright degree of the seedling due to the excess invalid drift.
Description
Technical field
The invention belongs to agricultural machinery, relate in particular to the capable high-speed transplanter transplanting mechanism of helical teeth alternating axis sex change elliptic gear width.
Background technology
The agronomy expert has proposed the capable dense planting agriculture requirement of paddy rice width through concentrating on studies to what paddy rice was planted for many years.Paddy rice dense planting technology helps improving ventilation and penetrating light property, reduces damage by disease and insect, improves rate of tillering panicle, particularly can improve advantages such as output 5%-10% to low-yield land.Along with the proposition of the agriculture requirement of the capable dense planting of width, the capable rice transplanter of width also begins one's study, and waiting the line-spacing rice transplanter is the technology of a comparative maturity; The capable rice transplanter of width all is to improve waiting on the line-spacing rice transplanter basis in the market, and implementation has two kinds, one; Change the seedling case; Changing the seedling case just needs to change the seedling dish, thereby the change that brings seedling raising method contradicts with the seedling raising method of maturation; Two, guarantee that the seedling case is constant, through changing transplanting mechanism; Transplanting mechanism has shifted gears two kinds, and a kind of is that new sun wheel shaft and transmission case central shaft form low-angle, and this scheme need change transmission case; Thereby make the structure of transmission case increase; Because the constant distance between the two seedling pins makes structure too compact, adjustability is poor; Another kind is to utilize planetary gear and the staggered mode of breast wheel helical gear, makes the seedling needle movement in a tapered plane, and this scheme is changed less; But applied speed change transmission planet circular system is original elliptic gear, off-centre a--non-circular gear; These gear drive gearratios are symmetrically distributed, and under the prerequisite that satisfies the rice transplanting requirement, the lateral shift availability that bring on the inclined plane is lower; Needing to increase helical gear helical angle realizes; Aggravated the wearing and tearing of gear, and the upright degree of too much invalid bias effect rice shoot, seedling hindered easily; And utilize non-round helical gear space interlace mode to realize that width is capable separately, non-round helical gear processing cost is high.
Summary of the invention
The object of the present invention is to provide a kind of can the change under the prerequisite that has rice transplanter structure and seedling link now, the transplanting mechanism of the capable rice transplanting of realization width reaches purpose rational in infrastructure, that orthostatic good, seedling-damaging ratio is low, with low cost.
The objective of the invention is to realize like this:
The capable high-speed transplanter transplanting mechanism of a kind of helical teeth alternating axis sex change elliptic gear width; On gear housing centre, be rotatably mounted sun sex change elliptical skew gear; Drive central shaft and be inserted in rotationally in the sun sex change elliptical skew gear centre bore, the end and the gear housing that drive central shaft are affixed; On gear housing inside portion, be positioned at drive central shaft bilateral symmetry position equipped in parallel to each other in the middle of wheel shaft; And star stereo staggered angle between wheel shaft axial line and the driving central shaft axial line in the middle of two; The angle value at this stereo staggered angle equates with the tooth angle of bevel value of sun sex change elliptical skew gear; The oval spur gear of anaplastic on the middle wheel shaft of both sides, all being equipped with, oval spur gear of described middle anaplastic and the engagement of sun sex change elliptical skew gear; On gear housing inside portion, be positioned in the middle of two antimere place, the wheel shafts outside respectively with the equipped in parallel to each other planet wheel spindle of middle wheel shaft; The oval spur gear of planet sex change is fitted on the planet wheel spindle, the oval spur gear engagement of oval spur gear of described planet sex change and middle anaplastic; As variable transmission mechanism, what on the planet wheel spindle outer end, be vertical angle installs the transplant arm assembly to described five sex change elliptic gears with the mode of planet circular system.
The beneficial effect that the present invention has is:
The present invention utilizes the sex change elliptic gear as variable transmission mechanism, and this gear pair can be realized the variable ratio transmission, and through regulating sex change Coefficient Control gearratio position; Sex change elliptic gear as sun gear is a helical gear, and all the other are spur gear, and wheel shaft and central shaft space are staggered in the middle of making; The rotational velocity of the sex change Coefficient Control planetary gear through changing the sex change elliptic gear; Improving tapered plane brings lateral shift to get availability; Reduced invalid lateral shift, the width that obtains agriculture requirement with the helical angle of minimum is capable, has avoided the too much invalid skew influence to the rice shoot upright degree; This mechanism is reasonable, the operation quality of planting is good, and damaged seedling rate is low.
