Description
Technical field
The invention belongs to agricultural machinery technological field, be specifically related to a kind of high-speed rice pot seedling transplanter seedling taking arm pushes away rice seedling distribution mechanism.
Background technology
It is the rice transplanting technology of a kind of high yield that accurate rice pot seedling is transplanted, and this technical advance is mainly reflected in: band trophosome plant educate,
Without seedling-slowing stage, survival rate height, length in growth period, volume increase substantially, by quantitatively positioning planting, seed costs is saved than conventional seed planting
More than 70%.Additionally, also can effectively solve that application rate present in blanket rice transplanter rice transplanting is big, miss in seedling setting rate is higher, the quality of seedlings
The problems such as difference, seedlings plugging are uneven.Compared with blanket rice transplanting, it is big that bowl rice transplanting technology is limited little, seedling age elasticity by transplanting time,
Fringe grain is big and many, and field nursing labour intensity is greatly lowered, and therefore, application prospect is the most wide.Pot seedling transplanter pushes away seedling dress
The effect put is to utilize planting arm taken off from rice seedling box of rice seedling transplanting machine by rice shoot and push it in paddy field, and then effectively prevents rice shoot from returning
Band and institute's rice transplanting seedling enter the phenomenon that mud is the deepest.Rice seedling transplanter ejects and presss from both sides seedling two ways, and existing folder seedling formula is planted
Do not push away rice seedling distribution mechanism between the left seedling-taking clamp of arm and right seedling-taking clamp, only rely on the opening and closing of seedling-taking clamp and grip and plant rice shoot.Make herein
Person have developed " Cam-pushrod seedling gripping mechanism of rice transplanting machine " planting arm that a kind of accurate rice pot seedling is transplanted in 2011, and applies for
Patent of invention (patent No.: 201110143592.9), in this patent of invention, planting arm does not push away seedling during rice transplanting and moves

The tooth of bar 30 and idler gear 28 is 4.
Operation principle and the course of work of the present invention are as follows:
Seedling taking: as it is shown in figure 1, planting arm does seedling taking and transplanting work, its medium power under the drive of planet gear type rotating mechanism
Axle 2 is affixed with planet gear type rotating mechanism housing, and planting arm housing 24 is affixed with the planet wheel spindle in planet gear type rotating mechanism.
Power, after planet gear type rotating mechanism passes to line shaft 2, drives line shaft 2 to rotate relative to planting arm housing 24, dynamic
Power axle 2 and then band moving cam 1 and transition gear I 25 rotate clockwise, and contact with roller 21 all the time in cam 1 rotation process,
During roller 21 with 1 first projection contacts of cam, promote fork 20 around swing link pin under the drive of roller 21
Axle 19 rotates counterclockwise, and fork 20 promotes push rod 12 to move along a straight line forward by extruding nut block 17, and push rod 12 leads to
Crossing push rod bearing pin 11 drives upper chain link I 7, upper chain link II 38, lower chain link I 6, lower chain link 40 to move, left seedling-taking clamp 8, the right side
Seedling-taking clamp 37 upper chain link I 7, on chain link II 38, lower chain link I 6, lower chain link II 40 and seedling clamp pin axle 9 effect under outwards
Opening, after turning over first boss, push rod 12 is rearward movement under the effect of back-moving spring I 16, left seedling-taking clamp 8 and the right side
Seedling-taking clamp 37 inwardly clamps and then clamps rice shoot at seedling taking point.
Rice transplanting: as it is shown in figure 1, after seedling has gripped rice shoot, roller 21 crosses 1 first projection of cam, now, pushes away
Bar 12 moves along a straight line backward under the effect of back-moving spring I 16 and promotes fork 20 to rotate clockwise so that roller 21 is in convex
Taking turns between 1 first projection and second projection, left seedling-taking clamp 8 and right seedling-taking clamp 36 stay closed all the time state, planting arm
When being taken to rice transplanting position by planet circular system rotating mechanism, now, roller 21 and 1 second projection contacts of cam, promote pendulum
Bar 20 rotates counterclockwise around fork bearing pin 19 under the drive of roller 21, and fork 20 is pushed away by extruding nut block 17
Bar 12 moves along a straight line forward, push rod 12 by push rod bearing pin 11 drive upper chain link I 7, upper chain link II 38, lower chain link I 6,
Lower chain link II 40 move, left seedling-taking clamp 8, right seedling-taking clamp 37 upper chain link I 7, on chain link II 38, lower chain link I 6, lower chain
Save II 40 and seedling clamp pin axle 9 effect under be flared out will release clamping seedling planting in earth.
Push away seedling: as it is shown in figure 1, after seedling folder rice transplanting completes, now, pushing sprout pole 33 is positioned at left seedling-taking clamp 8 and right seedling taking
Pressing from both sides immediately below 37 centre positions foremost, i.e. push away seedling and complete a little, idler gear 28 now prepares and cylinder tooth bar 30 right-hand member
First tooth is engaged, and then line shaft 2 then rotates counterclockwise, and transition gear I 25 is under the drive of line shaft 2
Rotating counterclockwise equally, transition gear I 25 and then drive transition gear II 26 do engagement rotation clockwise on jackshaft 29,
Idler gear 28 is affixed with transition gear II 26 to be rotated clockwise, and idler gear 28 starts to drive circle during rotating
Post tooth bar 30 compression reseting spring II 35 backward moves along a straight line, when soon departing from after the engagement through four gears, and cylinder
First tooth of tooth bar 30 right-hand member crosses shift fork 48, and then cylinder tooth bar 30 is protected under torsion spring 47 pretension active force by shift fork 48
Holding in compressive state, transition gear II 26 then rotates when going to rice transplanting position, now, and left seedling-taking clamp 8, right seedling taking
Folder 37 releasing clamping to rice shoot, the triggering boss 27 on transition gear II 26 contacts with shift fork 48 and promotes shift fork 48 around pin
Axle II 49 rotates clockwise, and shift fork 48 releases the control to cylinder tooth bar 30, and cylinder tooth bar 30 is at the bullet of back-moving spring II 35
Released rapidly under power, complete to push away seedling.
