When the potato seed sowing device is installed, the sowing device is installed on a potato positive bud sowing machine pulled by a tractor, the lower end of a seed protection cover 7 is positioned behind a furrow opener of the potato sowing machine, a driving shaft 3 is connected with power input equipment, the power input equipment can be a power output shaft on a traction tool, a sowing machine ground wheel or an independent synchronous driving motor, and the driving shaft 3 can be connected with the power input equipment in various modes such as a coupling, a chain, a gear set, a synchronous belt and the like. The power input device can drive the driving chain 5 to rotate through the driving shaft 3, and the supporting claws 6 on the driving chain 5 move circularly along with the chain and sequentially pass through the seed protecting cover 7 from top to bottom. After the driving motor 12 is started, the first rocker arm 13 can be driven to rotate, the second rocker arm 17 is driven to synchronously rotate by the connecting rod 15 in the rotating process of the first rocker arm 13, the first hinge shaft 14 and the second hinge shaft 16 at two ends of the connecting rod 15 respectively drive the first crank arm 18 and the second crank arm 20 to synchronously move, the other ends of the first crank arm 18 and the second crank arm 20 are respectively limited by the first pull rod 19 and the second pull rod 21, so that the driving plate 22 arranged at the corner of the first crank arm 18 and the second crank arm 20 can realize the cyclic movement of ascending → advancing → descending → retreating, after the driving plate 22 ascends, the shifting teeth 23 on the driving plate 22 are meshed with the teeth of the transmission synchronous belt 11, when the driving plate 22 advances, the transmission synchronous belt 11 can be driven to advance, when the driving plate 22 descends, the shifting teeth 23 on the driving plate 22 are separated from the teeth of the transmission synchronous belt 11, so that the transmission synchronous belt 11 cannot be driven to move backwards in the process of moving backwards of the driving plate 22. The above structure enables smooth stepping of the conveying timing belt 11. Before sowing, the rotation speed of the driving motor 12 is adjusted to step the conveying timing belt 11 once every time one of the holding claws 6 falls to the end of the conveying timing belt 11. During the seeding, seed potato bud piece that will divide according to standard size in advance cut and bud pours into kind potato case 24, start the electromagnetic shaker 26 of seed potato case 24 bottom installation, make kind potato case 24 and lead kind of groove 25 vibrations, seed potato bud piece in kind potato case 24 continues to slide to conveying synchronous belt 11 along the guide kind groove 25 of slope under the vibration effect on, along with conveying synchronous belt 11's step-by-step, a plurality of kinds of potato bud pieces become one row on conveying synchronous belt 11, conveying synchronous belt 11 carries seed potato bud piece in proper order on each support claw 6 through conveying synchronous belt 11 is terminal, along with tractor traction seeder furrow opener rectilinear driving in the field, the furrow opener is opened out kind of ditch, support claw 6 carries kind potato bud piece and gets into kind ditch, can directly leave kind potato bud piece among kind of ditch.

Seed potato bud piece is cutting the back, the potato bud all is located seed potato surface's convex surface, the plane that the cutter formed does not have the potato bud, seed potato pours into seed potato case 24 after along with seed potato case 24's vibrations, most seed potato bud pieces all can slide in the plane steady state down to the seed tank 25 with the cutter formation, operating personnel only need observe seed potato bud piece on seed potato case 24 next door, find out the potato bud and turn over it by the back-off bud piece in the bottom, the potato bud is pressed in seed potato below and is influenced when avoiding the bud piece to get into the kind ditch and emerge. The invention has the advantages that operators do not need to operate each potato bud one by one, and compared with the existing potato seeding equipment, the labor intensity of the operators is obviously lower. Seed potato bud piece is followed and is led kind of groove 25 to sliding down on conveying hold-in range 11 and when following conveying hold-in range 11 to the landing on the support claw 6, and the difference in height is very little, keeps the plane steady state down when seed potato bud piece removes to not take place to roll, and the potato bud can be guaranteed to seed potato bud piece and can effectively emerge up or towards the side when getting into kind of ditch. Even there are few kind potato bud piece and do not reach the steady state that the plane faced down under the effect of vibrations, as long as the potato bud is not directly pushed down by the bud piece, also can normally emerge, operating personnel can overturn it in kind of potato case when discovering that the potato bud is pushed down by the bud piece.

The invention adopts a potato block feeding mode that the stepping of the conveying synchronous belt 11 is matched with the circular downward movement of the supporting claw 6, can realize that potato bud blocks are stably fed into the seed ditch one by one, the stepping of the conveying synchronous belt 11 is realized by a mechanical device, and the driving motor 12 continuously rotates.

In order to reduce the influence of the vibration of the potato planting box 24 on the sowing machine, a spring foot pad 27 can be arranged at the edge position of the bottom of the potato planting box 24. The spring foot pad 27 can absorb most of the vibration and relieve the discomfort of the driver and passengers caused by the vibration of the potato planting box 24.

In order to improve the sowing efficiency, the invention can adopt the following structure: the two sets of the seed falling devices are arranged in opposite directions, transverse plates 9 on the two sets of the seed falling devices are mutually connected, driving shafts 3 of the two sets of the seed falling devices are connected through transmission shafts, and universal joints 29 are arranged on the transmission shafts. During installation, two sets of the seed falling devices can be respectively positioned on two sides of the seeder, two ridges of potatoes can be sown simultaneously in the operation of the seeder, the driving shafts 3 of the two sets of the seed falling devices can rotate synchronously, and the universal joint 29 arranged on the driving shaft can eliminate the stress between the two driving shafts 3 when the seeder works on the fluctuating ground surface in the field.

In order to be suitable for agricultural delivery vehicles with various widths, the invention can adopt the following structure: diaphragm 9 of two sets of falling kind of devices all passes through bolted connection with same connecting plate 30, sets up a plurality of adjusting bolt holes 31 on the connecting plate, and transmission shaft between the drive shaft 3 of two sets of falling kind of devices includes a square shaft 28 and one and square sleeve 32 of this square shaft 28 complex, and square shaft 28 can slide along square sleeve 32's length direction, the sprout tuber export bottom plate of leading kind of groove 25 bottom plate and kind potato case 24 is articulated, is connected through flexible soft board 35 between the play mouth curb plate of leading kind of groove 25 curb plate and kind potato case 24. The structure enables the distance between the two groups of seed falling devices to be adjusted within a certain range, is not limited by the width of the seeder, and enlarges the application range of the invention. The angle between the sprout tuber outlets of the seed guiding groove 25 and the seed potato box 24 can change along with the actual position of the conveying synchronous belt 11, so that the seeds can be still smoothly discharged after the distance between the two groups of seed falling devices is changed.

In order to enhance the stability of the transmission synchronous belt 11 during stepping, synchronous wheels can be arranged on the output shaft of the driving motor 12 and the rotating shaft of the second rocker arm 17, and the synchronous wheels of the two shafts are driven by a synchronous belt 36. The synchronous belt 36 and the connecting rod 15 jointly realize synchronous transmission between the first rocker arm 13 and the second rocker arm 17, so that the shaking of the rocker arms can be effectively eliminated, and the stability during transmission is enhanced.
