Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.
Small-sized line feed reciprocating working chassis main view schematic diagram shown in Fig. 1, small-sized line feed reciprocating working chassis includes：Two groups
Line feed mechanism is respectively fixedly connected with the vehicle frame front and back ends in power chassis 8 by support 7, and two groups of line feed mechanism kinematic planes are hung down respectively
Directly in operating speed direction v (as shown in Figure 2) of power chassis 8；Wherein：Power chassis 8 are general small-size tractor, work as crop
When Planting Row Distance is h, power chassis wheelspan takes h, 2h, 3h or 4h.
In small-sized line feed reciprocating working chassis main view schematic diagram shown in Fig. 1, line feed mechanism by driving crank 1, connecting rod 2,
Driving crank 3, side link 4, support rod 5, supporting boots 6 constitute, wherein driving crank 1, connecting rod 2, driving crank 3, side link 4 according to
Secondary order rotation connection, each pivot center are parallel, and driving crank 1 is isometric with driving crank 3, and connecting rod 2 is isometric with side link 4, main
Dynamic crank 1, connecting rod 2, driving crank 3, side link 4 constitute same relative motion plane in parallel quadrangular mechanism, and supporting boots 6 lead to
Cross support rod 5 to be connected with connecting rod 2, connecting rod 2, support rod 5 and the supporting composition of boots 6 are located at parallel-crank mechanism relative motion plane
Interior same rigid motion body, driving crank 1, connecting rod 2, driving crank 3, side link 4, support rod 5, supporting boots 6 form line feed
Mechanism；The side link 4 of two groups of line feed mechanisms is respectively fixedly connected with the vehicle frame front and back ends in power chassis 8, the length of support 7 by support 7
Degree b can be adjusted by hydraulic jack, lock hydraulic control valve after adjustment, to ensure the side link 4, support of line feed mechanism
7 are solidly fixed with the vehicle frame of power chassis 8.
Small-sized line feed reciprocating working chassis line feed schematic diagram shown in Fig. 3, small-sized line feed reciprocating working chassis is adopted in field
With the reciprocating working mode that moves forward and backward, in operation process：After power chassis are advanced to up to field along v, driving crank
Rotate one week, when driving crank turns over line feed angle a, power chassis complete the transverse shifting perpendicular to operating speed direction v, move
Move row distance d and realize line feed, power chassis are drawn back along-v and worked on after the completion of line feed；When power chassis are drawn back along-v
After reaching the field other end edge of a field, driving crank is rotated one week, and the line feed of power chassis transverse shifting is entered a new line again apart from d, is changed
After the completion of row, power chassis march forward along v and work on.When driving crank length is e, enter a new line apart from d=2*e*sin (a/2),
Line feed obstacle clearing capability g=e* [1-cos (a/2)], when the tire ground sinkage of power chassis is different or supporting boots are connect with ground
When tactile height c changes, by adjusting length b of support, and keep line feed angle a constant, then enter a new line constant apart from d=h.
Small-sized line feed reciprocating working chassis line feed procedure chart shown in Fig. 4, when power chassis reach field line feed, main
Dynamic crank is rotated 1 week, in rotation process：Supporting boots are come into contact with supporting boots with ground and are disengaged with ground, corresponding active
Crank turns over line feed angle a, and power chassis complete the transverse shifting perpendicular to operating speed direction v, and a mobile line feed is apart from d realities
1 row is now changed, and when driving crank goes to a/2, across the high surface in ridge, enter a new line wheel obstacle clearing capability g=e* [1-cos (a/2)],
When the obstacle clearing capability that enters a new line is high more than ridge, the high line feed in ridge crossed by wheel does not affect ridge field cropses to grow.
Crop-planting line-spacing h is set, row distance d=h is taken；When operation line number is 1, during line feed, driving crank rotates 1 turn,
Now power chassis displacement h；Operation line number be 2 when, during line feed driving crank rotate 2 turns, now power chassis movement away from
From 2h；When operation line number is 3, during line feed, driving crank rotates 3 turns, now power chassis displacement 3h；Operation line number is 4
When, during line feed, driving crank rotates 4 turns, now power chassis displacement 4h.
In order to reduce driving crank driving torque, power chassis stability when improving line feed takes row distance d=h/2, main
Dynamic crank rotates 2 turns, now power chassis displacement h；Move 2 line feed to realize changing 1 row apart from d.Realized by line feed
Power chassis move forward and backward reciprocating working, improve operation coverage rate and working performance.
