The eccentricity of each eccentric gear is equal to or less than 0.065; the drive sprocket shaft rotates by 360 DEG to carry out rice planting for three times with high seedling planting efficiency, good moving stationarity and reliable operation.
Description
The add-drop that the utility model relates to a kind ofly motor-drivenly can finish seedling taking when planting rice seedling, push away seedling and rice transplanting is put.
At present, the add-drop of the power rice-transplantor of domestic and international disclosed use is put and mainly is divided into two big classes, and a kind of is to adopt the add-drop of toggle to put, and its seedling pawl is fixed on the connecting rod, and the motion of crank drivening rod is put add-drop and finished seedling taking and transplanting work.But the rice transplanting frequency that this add-drop is put is 200-220 time/minute, increase along with the rice transplanting frequency, seedling-transplanting device vibration aggravation, stable working is poor, the increase of operating frequency simultaneously also makes the linear velocity of seedling pawl strengthen, and produces the inequality of separating seedlings or planting, causing damaged seedling rate and leaking the rate of inserting increases, and rice transplanting is of low quality.Another kind is the power rice-transplantor that existing Japan produces, its add-drop is put by the eccentric sloth wheel gear between two groups of eccentric central gears, eccentric planet gear and two gears and is constituted the eccentric gearing train, two push away rice seedling distribution mechanism and seedling pawl and plant and put arm and be distributed on each and divide on subrack body, but driving shaft twice of the rice transplanting that rotate a circle during work, rice transplanting frequency 350～400 times/minute, improved the operating efficiency of rice transplanting than crank connecting link transplanting mechanism, and the linear velocity of seedling pawl reduced near half, thereby realized low damaged seedling rate, improved the rice transplanting quality, and vibration reduces.
The purpose of this utility model provides that a kind of transplanting work efficient is higher, and robust motion is better, and the add-drop of the power rice-transplantor of reliable operation is put.
The utility model is that the technical scheme that achieves the above object is: a kind of add-drop of power rice-transplantor is put, comprise that the middle part is equipped with the drive chain wheel shaft that drive sprocket, two ends are respectively installed with eccentric central gear and are connected with gear housing, be contained in the eccentric sloth wheel gear on the jackshaft and be contained in eccentric planet gear and the plug in transmission mechanism of set of bearings composition on the slotting arm axle of branch; The slotting arm axle sky of branch is enclosed within the branch that is connected with gear housing and inserts on the wheel shaft, and the transplant arm that the seedling pawl is housed is connected with dividing slotting arm axle; The cam rocker arm, transplanting rod, the spring formation that are connected slotting wheel shaft one end of branch push away rice seedling distribution mechanism, it is characterized in that: the circumferential of eccentric central gear formed three hair style Eccentric Gear-drive mechanisms by three groups of uniform eccentric sloth wheel gears and three groups of eccentric planet gears engaged respectively, and the eccentricity of each eccentric gear all≤0.065.Rotation by the eccentric planet gear and realize seedling taking that add-drop puts, push away seedling and rice transplanting process with the synthetic variable-speed motion of the revolution of gear housing, and reach the movement locus of seedling pawl the best.
The utility model adopts the advantage after the technique scheme to be: plug in transmission mechanism owing to adopt three hair style eccentric gears to divide, the drive chain wheel shaft rotates a circle, but rice transplanting three times, the rice transplanting frequency is obviously put than the add-drop of the rice transplanter of Japan and is exceeded 1/3, rice transplanting efficient is higher, and because the linear velocity of seedling pawl reduces nearly 1/3, so robust motion is better, divide slotting precision higher, leakage is inserted rate and is colluded damaged seedling rate and descends greatly, and operation quality is stable, all in addition eccentric gears all adopt the small eccentricity rate, it is little that add-drop is put vibration, and it is more reliable to work, and can realize the rice transplanting requirement of spacing in the rows between 12～18cm.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
The add-drop of power rice-transplantor is as shown in Figure 1, 2 put, comprise drive chain wheel shaft 11, eccentric central gear 12, jackshaft 9, eccentric sloth wheel gear 10, divide and insert arm axle 14, the slotting wheel shaft 7 of branch, eccentric planet gear 8 and the plug in transmission mechanism of set of bearings composition, the drive chain wheel shaft 11 that drive sprocket 13 is equipped with at the middle part is arranged in the drive chain case 15, and power is input on the drive sprocket 13 by chain.The two ends of drive chain wheel shaft 11 are respectively installed with eccentric central gear 12, and drive chain wheel shaft 11 is connected with gear housing 6 by pivot pin, and drive chain wheel shaft 11 driven wheel casings 6 and eccentric central gear 12 together rotate.Eccentric central gear 12 is by eccentric planet gear 8 engagements on the slotting arm axle 14 of eccentric sloth wheel gear on the jackshaft 9 10 and branch, and the number of teeth of eccentric central gear 12, eccentric sloth wheel gear 9 and eccentric planet gear 10 is identical.Divide slotting arm axle 14 skies to be enclosed within on the slotting wheel shaft 7 of branch, divide and insert wheel shaft 7 by being connected with gear housing 6 with the end cap 16 of its welding, transplant arm 3 is installed on the slotting arm axle 14 of branch, and seedling pawl 2 is contained on the transplant arm 3.The cam rocker arm 4 that is connected slotting wheel shaft 7 one ends of branch joins with transplanting rod 1, and spring 5 is arranged on the top of transplanting rod 1, together constitutes to push away rice seedling distribution mechanism.Eccentric central gear 12 circumferentially form three hair style Eccentric Gear-drive mechanisms by three groups of uniform eccentric sloth wheel gears 10 and 8 engagements of three groups of eccentric planet gears respectively, the eccentricity of each eccentric gear is equal≤0.065, the vibration of putting with further minimizing add-drop.
For ease of installing, as shown in Figure 2, gear housing 6 is two packaging structures.
When the add-drop of power rice-transplantor of the present utility model is put work, power orders about drive chain wheel shaft 11 by chain, drive sprocket 13 and rotates, drive chain wheel shaft 11 drives eccentric central gear 12 and gear housing 6 rotates, transplant arm 3 together rotates with gear housing 6, eccentric central gear 12 drives eccentric planet gear 8 by eccentric sloth wheel gear 10 and rotates, at this moment the branch that is connected with eccentric planet gear 8 rotating speed of inserting arm axle 14 and transplant arm 3 produces difference with the rotating speed of cam rocker arm 4, and cam rocker arm 4 orders about transplanting rod 1 and moves up and down and finish the seedling process that pushes away.
