Degree is the straightway of 1mm/10mm；The starting point of the described section of planting seedlings is starting point of planting seedlings, and its initial segment is perpendicular
Straight setting and linearity are the straightway of 1mm/10mm；Described enters the changeover portion that alms bowl section is seedling taking section.
The beneficial effects of the utility model:
1, this utility model realizes monocycle buckle-like track, and monocycle buckle-like track is possible not only to ensure the seedling taking stage
Insert with suitable attitude, it can also be ensured that at vertical section track, flowers Seedling is directly inserted perpendicularly in floral disc,
The upright degree that plants seedlings is greatly improved, it is ensured that flowers plant seedlings suitable angle, speed, plant seedlings upright
Degree and the agriculture requirement preferably meeting flowers transplanting.
2, monocycle buckle-like track meet pot seedling transplanter put down into alms bowl, directly lift seedlings, the transplanting agronomy that surely plants seedlings is wanted
Ask；The characteristics of motion of rocking bar is controlled, it is achieved monocycle button track, mechanism's letter by changing the profile of cam
Single, it is easy to control so that seedling taking and the action planted seedlings are more flexible, and flexibility is high, for realizing other farmings
The transplanting machine generalization of thing achieves breakthrough, thus realize the crop such as flowers, melon fruits and vegetables complete from
Dynamic transplanting.
Accompanying drawing explanation
Fig. 1 is this utility model mechanism principle figure at initial position.
Fig. 2 is transplanting path figure of the present utility model.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, cam crank rocking bar combination flowers transplanting mechanism, including camshaft, fork-shaped
Fork, first connecting rod 2, second connecting rod 3, crank 4, spring 6, roller 7 and cam 8；Camshaft cuts with scissors
It is connected in frame 5, and is driven by motor M1；One end of cam 8 and crank 4 is all affixed with camshaft；
The other end of crank 4 is hinged with the middle part of second connecting rod 3；Fork-shaped fork includes what bottom welded together
Swing arm 1 and cam swing；The bottom of fork-shaped fork is articulated with frame 5, the two ends of spring 6 respectively with fork
Shape fork and frame 5 connect；Roller 7 is hinged with the top of cam swing, and constitutes cam with cam 8
Secondary；The top of swing arm 1 is hinged with one end of first connecting rod 2；The other end of first connecting rod 2 and second
One end of connecting rod 3 is hinged；The other end of second connecting rod 3 freely arranges and is formed monocycle button track.
Fork-shaped fork acts on lower swing jointly at spring 6, roller 7 and cam 8, and by power through
One connecting rod 2 and second connecting rod 3 pass at second connecting rod 3 free end end points F, the motion rule of end points F
Restrain and controlled by the cam contour of cam 8.
The monocycle button track mathematical model that the free end end points F of second connecting rod 3 is formed is non-based on three times
Uniform B-Spline Curve is set up.
As in figure 2 it is shown, choose 11 data points q0, q1, q2, q3, q4, q5, q6, q7, q8,
Q9 and q10 is as the data point of cubic nonratio-nal B-spline curve, and wherein, q0 and q10 overlaps, can be only
One solves 13 control vertexs, then to choose step-length be that a value interpolation in 0.005～0.02 generates
Match point coordinate, and then simulate monocycle button track.
11 data points are chosen as follows: q0 and q10 determines monocycle button track by flowers transplanting agriculture requirement
Peak, q1 determines the seedling taking starting point of monocycle button track, and q2 is to affect the pass of track attitude before seedling taking
Key point, q3 determines the seedling taking moment point of monocycle button track, and q4 determines the minimum point of monocycle button track, and q5 is true
The end point of planting seedlings of order latch closure track, q6 determines the starting point of planting seedlings of monocycle button track, q7, q8 and q9
It it is the auxiliary match point of monocycle button track；Simulate the free end end points F of second connecting rod 3 in coordinate system XOY
Formed in displacement equation be φfT (), wherein, crank 4 and frame pin joint are coordinate origin O；
φfT () is respectively φ in the displacement of X and Y directionfx(t) and φfyT (), t is for along the seedling pick-up trajectory side of moving
To the match point sequence number of number consecutively, during t=1, the free end end points F of second connecting rod 3 is in such as Fig. 1 institute
The initial position shown.
Monocycle button track is closing and the plane smooth curve with monocycle button, connects including order head and the tail successively
Connect enters alms bowl section 2-1, seedling taking section 2-2, fortune Seedling section 2-3, the section of planting seedlings 2-4 and replys section 2-5；Seedling taking
The starting point of section 2-2 and end point are the starting point of monocycle button, and its ending segment is for being parallel to hole tray Pan Kou
Lower wall and linearity are the straightway of 1mm/10mm, it is ensured that take out seedling along vertical soil alms bowl direction；Plant seedlings
The starting point of section 2-4 is starting point of planting seedlings, and its initial segment is to be vertically arranged and linearity is 1mm/10mm's
Straightway, it is ensured that seedling and planting mechanism only exist relative velocity vertically, is beneficial to vertical by Seedling
It is implanted directly into floral disc；Enter the changeover portion that alms bowl section 2-1 is seedling taking section 2-2；Visible, these flowers transplant track
Putting down into alms bowl, straight seedling taking and the requirement surely planted seedlings of seedling taking in flowers potted-seedling transplanting can be met.
This cam crank rocking bar combination flowers transplanting mechanism, the free end of second connecting rod 3 installs planting mechanism
