according to the seeder with adjustable spacing, the driving motor is started to drive the rotating column and the gear positioned at the front side to rotate clockwise, the soil poking plate at the front side is driven to realize circulation of downward, backward, upward and forward movement through cooperation with the corresponding sliding rod, the round rod and the return track, and meanwhile, the rotating column at the rear side is driven to rotate through meshing with the gear at the rear side, so that the soil poking plate at the rear side is driven to realize circulation of downward, forward, upward and backward movement, and the soil poking plate can be gradually contacted with soil in the downward process of the two soil poking plates and then mutually approaches, and the soil at the front side and the rear side of a groove formed in a plow head is poked to the middle so as to realize automatic burial of seeds, and the survival rate is prevented from being influenced by the outside;

according to the seeder with adjustable spacing, the dial-down handle drives the cross plate to move downwards so as to be separated from the positioning groove, then the extending plate is horizontally shifted to drive the rotating wheel to rotate, the rotating wheel drives the connecting column to move away from or close to the mounting shaft through the cooperation of the plurality of arc holes and the corresponding connecting column when rotating, the connecting column is driven to move away from the mounting shaft when the rotating wheel rotates clockwise, the arc supporting plate is driven to move away from the rotating drum through the mounting plate, so that the supporting radius of the arc supporting plate is enlarged, the rotating speed of the rotating drum is reduced under the same moving speed of the seeder shell, the rotating speed of the discharging wheel is reduced, so that the spacing between sowing at two sides can be increased, otherwise, the seeding spacing is reduced when the rotating wheel rotates anticlockwise, the handle is loosened after the adjustment is finished, the cross plate resets under the elastic force of the pressure spring and is clamped into the corresponding positioning groove, so that the seeding spacing is fixed, and different growing environments can be met;

according to the seeder with adjustable spacing, the worm is driven to rotate by the rotary knob, the worm drives the screw rod to rotate by meshing with the worm wheel, and the screw rod drives the adjusting plate to move up and down in the discharging groove by being matched with the threads of the thread groove and under the guidance of the guide rod, so that the volume of the discharging groove is adjusted, and the single seeding amount of the discharging groove is adjusted;

according to the spacing-adjustable seeder, after seeds in the seeder shell are completely consumed, as no seeds push the convex columns to move backwards, the push columns push the push plate to move leftwards through being abutted with the push plate in the process of driving the discharging wheel to rotate, and the push plate is limited by the limiting plate and the reset spring to move leftwards after being pushed for a certain distance, so that the rotation of the discharging wheel is limited in turn, the rotation of the rotary drum is limited under the action of the belt, the advancing resistance of the seeder shell is increased sharply, a user is reminded that the seeds are not enough, and the time waste caused by the fact that the finding of the seed quantity is not timely is prevented;

according to the seeder with the adjustable space, the L-shaped rod is driven to rotate clockwise around the fixed shaft by the pull rod in the leftward movement process of the push plate, the top end of the L-shaped rod moves downwards, the left end of the connecting rod is subjected to downward pulling force under the cooperation of the arc-shaped rod, the rotating shaft is driven to rotate anticlockwise, the rotating shaft drives the rotating lug and the cover plate to rotate anticlockwise for opening, and therefore seeds can be conveniently added into the seeder shell;

according to the seeder with adjustable spacing, the second electric push rod is started to drive the supporting wheel to move downwards, so that the supporting wheel is contacted with the ground, the right side of the seeder shell is supported, the arc-shaped supporting plate is separated from the ground, the first electric push rod can be started to retract the plow head, and therefore normal movement of the seeder shell can be guaranteed in a road section where seeding is required.

in the sowing process, after the seeds in the seeder housing 1 are completely consumed, as no seeds push the convex columns 30 to move backwards, in the process of continuously pushing the seeder housing 1 to move and driving the discharging wheel 10 to rotate, the push columns 34 push the push plate 26 to move leftwards through abutting with the push plate 26, and are limited by the limiting plate 28 and the reset spring 27 to be difficult to continuously move after being pushed leftwards for a certain distance, so that the rotation of the discharging wheel 10 is limited in turn, and the rotation of the rotary drum 2 is limited under the action of the belt 14, so that the advancing resistance of the seeder housing 1 is rapidly increased to remind a user that the seeds are insufficient;

and can drive L type pole 24 through pull rod 25 and carry out clockwise rotation around fixed axle 21 in push pedal 26 left motion in-process to make the top of L type pole 24 move downwards, thereby make the left end of connecting rod 22 receive decurrent pulling force under the cooperation of arc pole 23, thereby drive pivot 9 counter-clockwise rotation, pivot 9 drive rotation ear 8 and apron 7 counter-clockwise rotation open, thereby conveniently carry out the interpolation of seed to seeder casing 1.
