Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.
Small-sized line feed reciprocating working chassis shown in FIG. 1 main view schematic diagram, small-sized line feed reciprocating working chassis include：Two groups
The vehicle frame front and back ends in power chassis 8 are respectively fixedly connected by holder 7 in line feed mechanism, and two groups of line feed mechanism kinematic planes are hung down respectively
Directly in the operating speed direction v (as shown in Figure 2) of power chassis 8；Wherein：Power chassis 8 is general small-size tractor, works as crop
When Planting Row Distance is h, power chassis wheelspan takes h, 2h, 3h or 4h.
In the main view schematic diagram of small-sized line feed reciprocating working chassis shown in FIG. 1, line feed mechanism by driving crank 1, connecting rod 2,
Driving crank 3, side link 4, support rod 5, bearing boots 6 form, wherein driving crank 1, connecting rod 2, driving crank 3, side link 4 according to
Secondary order rotation connection, each pivot center is parallel, and driving crank 1 and driving crank 3 are isometric, and connecting rod 2 and side link 4 are isometric, main

It crosses support rod 5 to be connected with connecting rod 2, connecting rod 2, support rod 5 and the bearing composition of boots 6 are located at parallelogram mechanism relative motion plane
Interior same rigid motion body, driving crank 1, connecting rod 2, driving crank 3, side link 4, support rod 5, bearing boots 6 form line feed
Mechanism；The vehicle frame front and back ends in power chassis 8, the length of holder 7 are respectively fixedly connected by holder 7 for the side link 4 of two groups of line feed mechanisms
Degree b can be adjusted by hydraulic cylinder, and hydraulic control valve is locked after adjustment, to ensure side link 4, the holder of line feed mechanism
7 are solidly fixed with the vehicle frame of power chassis 8.
Enter a new line schematic diagram on small-sized line feed reciprocating working chassis shown in Fig. 3, and small-sized line feed reciprocating working chassis is adopted in field
With the reciprocating working mode that moves forward and backward, in operation process：Power chassis is advanced to along v up to after field, driving crank
Rotation one week, when driving crank turns over line feed angle a, power chassis completes the transverse shifting perpendicular to operating speed direction v, moves
Move row distance d and realize line feed, power chassis draws back along-v and works on after the completion of line feed；When power chassis is drawn back along-v
After reaching the field other end edge of a field, driving crank rotates one week, and power chassis transverse shifting line feed distance d enters a new line again, changes
Power chassis marches forward along v and works on after the completion of row.When driving crank length is e, enter a new line distance d=2*e*sin (a/2),
Enter a new line obstacle clearing capability g=e* [1-cos (a/2)], when the tire ground sinkage of power chassis is different or bearing boots connect with ground
When touching height c variations, by adjusting the length b of holder, and keep line feed angle a constant, then the distance d=h that enters a new line is constant.
Enter a new line procedure chart on small-sized line feed reciprocating working chassis shown in Fig. 4, main when power chassis reaches field line feed
Dynamic crank rotates 1 week, in rotation process：Bearing boots come into contact with bearing boots with ground and are disengaged with ground, corresponding active
Crank turns over line feed angle a, and power chassis completes the transverse shifting perpendicular to operating speed direction v, and mobile line feed distance d is real
1 row is now changed, when driving crank goes to a/2, wheel is across the high surface in ridge, and enter a new line obstacle clearing capability g=e* [1-cos (a/2)],
When the obstacle clearing capability that enters a new line is high more than ridge, wheel, which crosses ridge height line feed, does not influence ridge field crops growth.
Crop-planting line-spacing h is set, row distance d=h is taken；When operation line number is 1, driving crank rotates 1 turn when line feed,
Power chassis displacement distance h at this time；When operation line number is 2, driving crank rotates 2 turns when line feed, power chassis movement at this time away from
From 2h；When operation line number is 3, driving crank rotates 3 turns when line feed, at this time power chassis displacement distance 3h；Operation line number is 4
When, driving crank rotates 4 turns when line feed, at this time power chassis displacement distance 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, at this time power chassis displacement distance h；1 row is changed in i.e. mobile 2 line feed distances d realizations.It is realized by entering a new line
Power chassis moves forward and backward reciprocating working, improves operation coverage rate and operating efficiency.
