The inner side of the driven wheel I3 is connected to the reverse-rotating screw 10, and the inner side of the driven wheel II4 is connected to the forward-rotating screw 11. Screw screws 10 are located at the rear of the frame 1, one on each side, and are all passed through the holes on the connecting block 12. , and all pass through the holes on the connecting block 12, each of the reverse-rotation screw 10 and the forward-rotation screw 11 is respectively connected with a seeder 6, and each of the reverse-rotation screw 10 and the forward-rotation screw A fixed slide bar 8 is installed parallel to it below the bar 11, and is connected with the connecting block 12. The fixed slide bar 8 passes through the seeder 6, and two fertilizer buckets 9 are installed symmetrically on the left and right sides of the frame 1. A ditching fertilizer applicator 7 is installed below the fertilizer bucket 9 and is fixed with the frame 1 by bolts. The working mechanism and principle of the ditching fertilization applicator 7 are the same as those of the seeder 6 .

The seeder 6 includes a connecting rod 601, the bottom of the connecting rod 601 is connected to a ditching foot 602, the rear side of the ditching foot 602 is equipped with a sowing transmission gear 604, and a seed box 603 is installed on the rear portion, and the connecting rod 601 The top is equipped with a lead screw nut 612, and the contact position between the lead screw nut 612 and the connecting rod 601 is equipped with a positioning pin 613, and the connecting rod 601 has a through hole 614 at the bottom of the lead screw nut (612, so The lead screw nut 612 cooperates with the reverse-rotation lead screw 10 or the forward-rotation lead screw 11, the through hole 614 cooperates with the slide rod 8, and the connecting frame 611 is connected to the upper part of the back of the connecting rod 601, and There is also a screw hole plate 608 connected with the connecting rod 601 at the bottom of the connecting frame 611, and the roller frame 607 is connected with the said roller frame 607. The middle part of the roller frame 607 has a hole, and the adjusting screw 610 passes through the hole on the roller frame 607.

Working principle of the present utility model: the adjustment mode of the main sowing row spacing of the present utility model is, when the positioning pins 613 of the two sowers 6 at one end of the frame 1 are not pulled out, the two sowers 6 are In the linkage state, the driving wheel 2 is rotated by the handle 5. When the driving wheel 2 rotates clockwise, the driven wheel I3 and the driven wheel II4 are driven to rotate counterclockwise, thereby driving the counter-rotating screw 10 and the forward-rotating screw 11 to rotate counterclockwise. The counterclockwise rotation of the counter-rotating screw 10 makes the seeder 6 connected to it move to the direction close to the driven wheel I3 under the drive of the screw nut 612, and the counterclockwise rotation of the screw 11 makes the seeder 6 connected to it Driven by the lead screw nut 612, it moves away from the driven wheel II4, so that the two seeders 6 located at one end of the frame 1 are far away from each other. At this time, the row spacing increases. Similarly, when the driving wheel 2 rotates counterclockwise , the two seeders 6 at one end of the frame 1 are close to each other, and the row spacing is reduced. When the positioning pin 613 on a seeder 6 is pulled out, the loss of the screw nut 612 and the radial Fixed, now when the screw mandrel drives the screw mandrel nut 612 to rotate, the lead screw nut 612 will rotate in the connecting rod 601, and cannot drive the whole seeder 6 to move along the screw mandrel, at this moment, only when rotating the driving wheel 2 The seeder 6 that has not pulled out the positioning pin 613 can move, and the seeder 6 that has been pulled out of the positioning pin 613 will not be able to move, thereby realizing the position adjustment to a single seeder 6 . The positions of the four seeders 6 are adjusted by operating the handles 5 located at both ends of the frame 1, so that the row spacing can be adjusted freely, and can be adjusted to wide and narrow row sowing methods or equal row spacing sowing methods with different width requirements.
