[0054] Working principle: When the oilseed rape planting site needs to be irrigated, the dragboard 10 is connected with the ox, and then the positions of the annular rings 31 and the extrusion rods 333 are adjusted according to the distances between the oilseed rapes, the distances between the oilseed rapes on the left and right sides are adjusted to adjust the distances between the annular rings 31, the positions of the annular rings 31 are determined, the corresponding extrusion rods 333 are selected according to the positions of the oilseed rapes in front and back, the extrusion rods 333 are determined, the extrusion rods 333 are rotated to extend from the inside of the threaded grooves 331, the extrusion rods 333 drive the follower plates 342 to move in the extending process, the second sealing plugs 345 are inserted into the inside of the insertion grooves 32 with the movement of the follower plates 342, and the positions of the annular rings 31 are locked.
[0055] When the dragboard 10 moves, the rollers 12 drive the roller shafts 11 to move with the movement of the rollers 12, the roller shafts 11 drive the first transmission wheels 151 to rotate, the first transmission wheels 151 drive the long rods 154 to rotate, the long rods 154 drive the strip-shaped rods 30 to rotate, the strip-shaped rods 30 drive the annular rings 31 to rotate, the annular rings 31 drive the extrusion rods 333 to rotate, the extrusion rods 333 extrude the lifting rods 253 in the rotating process, the lifting rods 253 are lowered into the recesses 252 to avoid the water and fertilizer in the water storage tanks 13 from continuing to enter the inside of the strip-shaped openings 171, and the first hook plates 255 and the second hook plates 258 are locked with the movement of the lifting rods 253 in the inside of the recesses 252, so that the second springs 257 are prevented from recovering.
[0056] When the extrusion rod 333 passes through the lifting rod 253 and moves to the turnover block 232, the extrusion rod 333 can push the turnover block 232 to move, the turnover block 232 drives the fixed block 222 to move, the fixed block 222 drives the sealing plate 223 to move, the sealing plate 223 drives the long tube 241 to move, the sealing of the water outlet hole 242 by the strip-shaped block 244 is released, so that the water and fertilizer in the long tube 241 can be discharged through the water outlet pipe 172 to irrigate the rape planting place, when the extrusion rod 333 passes through the turnover block 232, the first spring 221 drives the fixed block 222 to move reversely, the fixed block 222 drives the sealing plate 223 to move, the sealing plate 223 drives the long tube 241 to move, the long tube 241 drives the limiting rod 243 to move to the strip-shaped block 244, and the sealing of the water outlet hole 242 is completed again, at the same time, the fixed block 222 drives the extrusion plate 259 to move, so that the extrusion plate 259 extrudes the side wall of the first hook plate 255, so that the first hook plate 255 is separated from the second hook plate 258, at this time, the second spring 257 drives the first hook plate 255 to rise, the first hook plate 255 drives the lifting rod 253 to rise, and the lifting rod 253 drives the limiting block 254 to move to the top of the strip-shaped hole 171, so that the water and fertilizer in the water storage tank 13 can re-enter the inside of the long tube 241, and the subsequent quantitative irrigation of the rape planting place is completed, when the first hook plate 255 rises, through the setting of the cutout 256, the first hook plate 255 can be prevented from contacting the extrusion plate 259 when the first hook plate 255 rises, and the normal rising of the first hook plate 255 is ensured.
[0057] When the drag plate 10 is reversely pushed, the circular ring 31 also reversely rotates, in order to ensure the normal movement of the drag plate 10, when the circular ring 31 reversely rotates, the circular ring 31 drives the extrusion rod 333 to rotate, the extrusion rod 333 drives the turnover block 232 to overturn when extruding the turnover block 232, and the turnover block 232 returns to the initial position under the driving of the elastic rope 233 after the extrusion rod 333 completely passes through the turnover block 232, so that subsequent irrigation of the rape is facilitated.
