Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a continuous potato planting device. Background Technology

[0002] Potatoes, as a dual-purpose crop for both food and vegetables, are widely valued due to their short growth cycle, strong soil adaptability, rich nutrition, high and stable yields, long industrial chain, and broad prospects for deep processing and utilization. Potato cultivation involves tasks such as ditching, fertilization, and sowing. Existing potato seeders can automatically ditch and fertilize, greatly reducing the labor intensity of workers. However, during sowing, issues such as missed planting, double planting, and uneven plant spacing are common. Furthermore, because potato seeds are relatively large, they often get stuck during sowing, preventing continuous sowing over extended periods and affecting planting efficiency. Utility Model Content

[0003] In view of the defects or deficiencies in the existing technology, this utility model provides a continuous potato planting device that can avoid the phenomena of missed planting, double planting and uneven plant spacing, while realizing continuous planting and improving the planting efficiency of potatoes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An embodiment of this utility model provides a continuous potato device, including a frame, a seed potato receiving and releasing mechanism, and a seed metering mechanism. The seed potato receiving and releasing mechanism is fixed above the rear side of the frame and includes a seed potato receiver, a drive shaft, and a drive assembly. The bottom end of the drive shaft is connected to the drive assembly through a drive block, and the seed potato receiver is sleeved on the outside of the drive shaft. The seed potato storage device includes multiple parallel storage trays, each with multiple storage holes. A seed leakage tray is provided between two adjacent storage trays, each with multiple seed leakage holes. The seed leakage trays are spaced apart by a set angle. The bottom of the seed potato storage device is provided with a base plate, which has multiple sets of through holes. Several through holes in each set of through holes correspond to several seed leakage holes on the bottommost seed leakage tray, and the through holes are spaced apart by a set angle. The seeding mechanism includes a pre-storage device located below the base plate. The pre-storage device has multiple pre-storage holes, which are corresponding to multiple through holes. A mechanical claw is located directly below each pre-storage hole, and the mechanical claw opens and closes by a pushing component.

[0005] Furthermore, several through holes within each group are arranged clockwise from the center of the base plate to the outside.

[0006] Furthermore, the base plate is sleeved on the outside of the transmission block and is rotatably connected to the transmission block.

[0007] Furthermore, the drive assembly includes a fourth motor and a planetary gear mechanism, the planetary gears having a set transmission ratio, and the fourth motor and the planetary gear mechanism being connected by a belt drive.

[0008] Furthermore, the planetary gear mechanism includes a sun gear, planet gears, and a ring gear. The sun gear is located at the bottom end of the transmission block, and a ring gear is fitted around the outside of the sun gear. The top of the ring gear is connected to the bottom plate, and internal teeth are provided on the lower part of the inner wall of the ring gear. The planet gears are located between the sun gear and the ring gear and mesh with the sun gear and the ring gear, respectively.

[0009] Furthermore, an opening and closing assembly is provided at the bottom of the pre-storage hole. The opening and closing assembly includes a first opening and closing plate and a second opening and closing plate. The first opening and closing plate and the second opening and closing plate are symmetrically arranged on both sides below the pre-storage hole. The ends of the first opening and closing plate and the second opening and closing plate away from the pre-storage hole are both hinged to the side wall of the pre-storage device.

[0010] Furthermore, a push plate is provided at the end of the first opening and closing plate away from the pre-store, a baffle is provided on the upper surface of the push plate, and a spring is provided between the baffle and the side wall of the pre-store.

[0011] Furthermore, the pre-storer is symmetrically provided with load-bearing rods on both sides. The load-bearing rods include a first support rod and a second support rod. The first support rod and the second support rod are connected by a fixing rod. A first drive motor is provided at the end of the first support rod, and a second drive motor is provided at the end of the second support rod. The output shafts of the first drive motor and the second drive motor are coaxially arranged, and a transmission disc is fixedly connected to the output shafts of both the first drive motor and the second drive motor.

[0012] Furthermore, the transmission disc is connected to the transmission rod via a connecting rod. One end of the connecting rod is rotatably connected to the outer surface of the transmission disc via a rotating shaft, and the other end is rotatably connected to the side wall of the transmission rod. The rotating shaft is eccentrically positioned relative to the transmission disc.

[0013] Furthermore, the transmission rod and the load-bearing rod are perpendicular to each other. The end of the transmission rod away from the pre-store is slidably connected to the connecting rod. The top end of the connecting rod is hinged to the frame. A connecting part is provided at the end of the transmission rod near the pre-store. Push blocks are provided on both sides of the top of the connecting part. The push blocks are correspondingly provided with the push plate. The mechanical claw and the pushing assembly are provided on the connecting part.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets a pre-storage device under the base plate, and drives the transmission shaft and the base plate to rotate through a drive component with a set transmission ratio. As the base plate rotates, the seed potatoes will fall into the pre-storage device from the outside to the inside. The opening and closing component set at the bottom of the pre-storage hole prevents the seed potatoes from falling further, thus realizing the pre-storage function, preparing for the next step of seed potato placement, ensuring the continuity of planting, and avoiding phenomena such as missed planting, double planting, and uneven plant spacing.

[0015] 2. This utility model features a mechanical claw positioned directly below the pre-storage hole. Multiple mechanical claws can be opened sequentially by a pushing component, allowing multiple seed potatoes located in the pre-storage hole to fall sequentially, thus achieving continuous sowing. After the seed potatoes in the pre-storage device are sown, the seed potato receiving and releasing mechanism continues to store seed potatoes in the pre-storage device via a base plate, driven by a drive mechanism, ensuring that seed potatoes fall each time the mechanical claws open, thereby achieving long-term continuous sowing.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] A typical embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a continuous potato planting device includes a frame 1, a traveling mechanism 2, a fertilizing mechanism 3, a ditch sealing mechanism 4, a seed potato receiving and releasing mechanism 5, and a seed metering mechanism 6. The traveling mechanism 2, the fertilizing mechanism 3, the ditch sealing mechanism 4, the seed potato receiving and releasing mechanism 5, and the seed metering mechanism 6 are all fixed on the frame 1.

[0019] The traveling mechanism 2 is located at the front of the frame 1 and cooperates with the casters 7 located at the rear of the frame 1 to enable the sowing device to move. The traveling mechanism 2 includes two track drive assemblies arranged side by side, such as... Figure 3 As shown, the track drive assembly includes two parallel first connecting plates 201 and second connecting plates, with a set distance between them. The first connecting plate 201 and the second connecting plate are connected by a support plate 207. A first drive wheel 202 and a second drive wheel 203 are disposed between the first connecting plate 201 and the second connecting plate. A first rotating shaft is fixedly connected to the axis of the first drive wheel 202, and a second rotating shaft is fixedly connected to the axis of the second drive wheel 203. The two ends of the first rotating shaft and the second rotating shaft pass through the first connecting plate 201 and the second connecting plate, respectively, and are rotatably connected to the frame 1. The first drive wheel 202 and the second drive wheel 203 are connected by a track 204.

[0020] Multiple buffer support rollers 205 are also provided between the first connecting plate 201 and the second connecting plate. The multiple buffer support rollers 205 are symmetrically arranged between the first drive wheel 202 and the second drive wheel 203. The multiple buffer support rollers 205 are in contact with the track 204. The two ends of the buffer support rollers 205 are respectively connected to the first connecting plate 201 and the second connecting plate. By setting the buffer support rollers 205, the track 204 is supported, thereby ensuring the smooth operation of the track 204. A pressure roller 206 is also rotatably connected between the first connecting plate 201 and the second connecting plate. Multiple pressure rollers 206 are arranged side by side at the lower part of the track drive assembly, and all multiple pressure rollers 206 are in contact with the track 204. The two ends of the pressure rollers 206 are respectively connected to the first connecting plate 201 and the second connecting plate. By setting multiple pressure rollers 206, the force angle generated after the track 204 contacts the bottom surface can be reduced.

[0021] A support frame 208 is provided on the outer side of the frame 1 near the first rotating shaft. A first motor 209 and a reducer 210 are fixedly connected to the support frame 208. The output shaft of the first motor 209 is connected to the first rotating shaft through the reducer 210, so that the first drive wheel 202 is rotated by the first motor 209, which in turn drives the track 204 to rotate.

[0022] Fertilizer applicator 3 is located on the front side of frame 1, above traveling mechanism 2, such as... Figure 4As shown, the fertilization mechanism 3 includes a fertilizer storage tank 303 and a cover 305 on top of the fertilizer storage tank 303. The bottom of the fertilizer storage tank 303 has an inverted conical structure, and an outlet is provided at the bottom of the fertilizer storage tank 303 to facilitate the flow of fertilizer from the outlet. A conveying pipe 304 is connected to the outlet at the bottom of the fertilizer storage tank 303. A sleeve 306 is provided at the end of the conveying pipe 304 away from the fertilizer storage tank 303. The sleeve 306 is connected to the fertilizer storage tank 303 through the conveying pipe 304. A spiral rod 302 is rotatably connected inside the sleeve 306. Figure 5 As shown, a second motor 301 is provided at the top of the sleeve 306. The output shaft of the second motor 301 is fixedly connected to the top of the screw rod 302, thereby driving the screw rod 302 to rotate. The fertilizer in the fertilizer storage box 303 flows out from the bottom outlet and flows into the sleeve 306 through the conveying pipe 304. Under the action of the screw rod 302, the fertilizer can be evenly sprinkled on the ground.

[0023] The trench sealing mechanism 4 is located in front of the auger rod 302, between the two track drive assemblies, such as... Figure 6 As shown, the trench sealing mechanism 4 includes a third motor 401, which is fixed on the frame 1. Multiple soil-breaking blades 402 are symmetrically arranged on the output shafts on both sides of the third motor 401. The soil-breaking blades 402 are arc-shaped. When the third motor 401 drives the soil-breaking blades 402 on both sides to rotate, the soil-breaking blades 402 come into contact with the ground soil, which can reserve space for potato planting and open up a fertilizer-free path in the fertilizer path spread by the fertilizer storage box 303. This maintains the reliability of fertilization and avoids damage caused by direct contact between potato seed tubers and fertilizer.

[0024] Seed potato receiving and dispensing mechanism 5 is located on the rear side of frame 1. Seed potato receiving and dispensing mechanism 5 includes a seed potato holder 510, a drive shaft 520, and a drive assembly 530. The seed potato holder 510 is sleeved on the outside of the drive shaft 520. Figure 7 As shown, the drive shaft 520 includes multiple connecting posts 521, each of which is cylindrical. The multiple connecting posts 521 are coaxially arranged and connected to each other by fixing blocks, as shown below. Figure 8 and Figure 9As shown, the fixing block includes a fixing groove 522 on the top of the connecting post 521 and a fixing protrusion 523 on the bottom of the connecting post 521. The fixing protrusion 523 and the fixing groove 522 are adapted to each other, so that the fixing protrusion 523 can be inserted into the fixing groove 522, thereby connecting the ends of multiple connecting posts 521. A bearing 524 is provided between two adjacent connecting posts 521. The bearing 524 is sleeved on the outside of the fixing block. Since the bearing 524 and the fixing block are in transition fit, the inner ring of the bearing 524 is used to fix the fixing protrusion 523 and the fixing groove 522, thereby ensuring the stability of the connection between the fixing protrusion 523 and the fixing groove 522 without external force intervention. By setting the fixing protrusion 523 and the fixing groove 522 on the connecting post 521, the drive shaft 520 becomes a detachable structure, which is convenient for storing seed potatoes.

[0025] like Figure 10 As shown, the seed potato collector 510 includes a top cover 511, a bottom plate 514, multiple collection trays 512, and multiple seed-leaking trays 513. The collection trays 512 and seed-leaking trays 513 are positioned between the top cover 511 and the bottom plate 514. The collection trays 512 are arranged in parallel, and the seed-leaking trays 513 are positioned between adjacent collection trays 512. Both the collection trays 512 and seed-leaking trays 513 are circular, with the same diameter. The collection trays 512 and seed-leaking trays 513 are coaxially arranged. Figure 11 As shown, the storage tray 512 has multiple storage holes 515, which are arranged radially from the center of the storage tray 512 to the outside, thus forming multiple rows of storage holes 515 arranged along the circumference of the storage tray 512. Each row of storage holes 515 is separated by a set angle. In this embodiment, each row of storage holes 515 includes four storage holes 515, and each row of storage holes 515 is separated by 20°.

[0026] like Figure 12 As shown, the seed-leaking tray 513 has multiple seed-leaking holes 516 arranged sequentially from the center to the outside of the seed-leaking tray 513. The multiple seed-leaking holes 516 correspond to the multiple storage holes 515 on the same row of the storage tray 512. Seeds placed in the upper storage tray 512 can fall into the lower storage tray 512 through the seed-leaking holes 516. The seed-leaking trays 513 are separated by a set angle. In this embodiment, the seed-leaking trays 513 are separated by 20°, so that the seed-leaking holes 516 on the two adjacent seed-leaking trays 513 correspond to the storage holes 515 in different directions of the storage tray 512. This arrangement can ensure that the seed potatoes in each row of the lower storage tray 512 are quickly replenished after the drive shaft 520 rotates, so that the seed potato receiving and placing mechanism 5 can save space and achieve efficient sowing in actual operation.

[0027] The base plate 514 is located below the lowest seed tray 513. The base plate 514 is circular, and its diameter is the same as that of the seed tray 513. It is also coaxially aligned with the seed tray 513. Figure 13 As shown, the base plate 514 is provided with multiple through holes 517, which are divided into four groups. The through holes 517 in each group are arranged clockwise from the center of the base plate 514 to the outside. The interval between two adjacent through holes 517 is set at a certain angle. The through holes 517 in each group on the base plate 514 correspond to the multiple seed leakage holes 516 on the bottom seed leakage tray 513. In this embodiment, four through holes 517 are provided in each group of through holes 517. The interval between two adjacent through holes 517 is 20°. That is, every time the base plate 514 rotates 20°, there is a through hole 517 that corresponds to the seed leakage hole 516 on the bottom seed leakage tray 513.

[0028] The storage tray 512 and the seed-leaving tray 513 are both sleeved on the outside of the drive shaft 520. The storage tray 512 is sleeved on the outside of the connecting post 521 and is keyed to the connecting post 521. The seed-leaving tray 513 is fixed on the outside of the bearing 524. The bottom end of the drive shaft 520 is connected to the drive assembly 530 through the drive block 525. The base plate 514 is sleeved on the drive block 525 and is rotatably connected to the drive block 525.

[0029] A limiting groove 518 is provided on the outer circular surface of the seed-discharging tray 513. A limiting plate is provided at the corresponding position of the frame 1 and the limiting groove 518. The limiting plate is adapted to the limiting groove 518 and can be locked in the limiting groove 518, so that the drive shaft 520 only drives the receiving tray 512 to rotate, preventing the seed-discharging tray 513 from rotating with the drive shaft 520 and ensuring the normal transmission of seed potatoes.

[0030] The drive component 530 is fixed below the seed potato storage unit 510, such as... Figure 14 As shown, the drive assembly 530 includes a fourth motor 531 and a planetary gear mechanism. The fourth motor 531 is located on one side of the planetary gear mechanism, as shown below. Figure 15 and Figure 16 As shown, the planetary gear mechanism includes a sun gear 532, planet gears 533, and a ring gear 534. The sun gear 532 is fixed to the bottom of the transmission block 525. The axis of the sun gear 532 is rotatably connected to the frame 1 through a first rotating shaft. The ring gear 534 is sleeved on the outer side of the sun gear 532. The lower part of the inner wall of the ring gear 534 is provided with internal teeth. The planet gears 533 are located between the sun gear 532 and the ring gear 534, and mesh with the sun gear 532 and the ring gear 534 respectively. The axis of the planet gears 533 is rotatably connected to the frame 1 through a second rotating shaft.

[0031] An annular groove is provided in the middle of the lower surface of the base plate 514. The annular groove is adapted to the top of the gear ring 534, and the top of the gear ring 534 can be inserted into the annular groove, thereby realizing the fixed connection between the gear ring 534 and the base plate 514. The top surface of the transmission block 525 is provided with a fixing groove 522, which can be adapted to the fixing protrusion 523 at the bottom of the transmission shaft 520, thereby realizing the connection between the transmission block 525 and the transmission shaft 520. When the sun gear 532 rotates, it can drive the transmission shaft 520 to rotate through the transmission block 525, and drive the base plate 514 to rotate through the planet gear 533 and the gear ring 534. In this embodiment, the transmission ratio of the planetary gear mechanism is 4:1, that is, when the base plate 514 completes one cycle of receiving, the upper receiving plate 512 rotates exactly 20°, and further realizes a new round of receiving and lower.

[0032] The output shaft of the fourth motor 531 is provided with a first pulley 535, and the sun gear 532 is provided with a second pulley 536. The second pulley 536 is coaxial with the sun gear 532. The first pulley 535 and the second pulley 536 are connected by a belt 537, which in turn drives the seed potato receiving and releasing mechanism 5 to move through the fourth motor 531.

[0033] The seed dispensing mechanism 6 is located below the seed potato receiving and dispensing mechanism 5, such as... Figure 17 As shown, the seed metering mechanism 6 includes a pre-storage component and a seeding component. The seeding component is located below the pre-storage component. The pre-storage component can temporarily store seed potatoes during seed planting, while the seeding component can perform continuous seeding.

[0034] like Figure 18 As shown, the pre-storage component includes a pre-storage device 610 and an opening and closing component. The pre-storage device 610 is located below the base plate 514. One end of the pre-storage device 610 is fixed on the frame 1. The upper surface of the pre-storage device 610 has multiple pre-storage holes 611, which correspond to multiple seed leakage holes 516 on the bottom seed leakage tray 513. In this embodiment, the pre-storage device 610 has four pre-storage holes 611.

[0035] The opening and closing assembly is located below the pre-storage hole 611 and is used to control the opening and closing of the bottom of the pre-storage hole 611. The opening and closing assembly includes a first opening and closing plate 621 and a second opening and closing plate 622. The first opening and closing plate 621 and the second opening and closing plate 622 are symmetrically arranged on both sides below the pre-storage hole 611. The bottom of the pre-storage hole 611 is blocked by the first opening and closing plate 621 and the second opening and closing plate 622. The ends of the first opening and closing plate 621 and the second opening and closing plate 622 away from the pre-storage hole 611 are both hinged to the side wall of the pre-storage device 610, so that the first opening and closing plate 621 and the second opening and closing plate 622 can rotate around the hinge point, thereby realizing the opening and closing of the bottom of the pre-storage hole 611.

[0036] The first opening and closing plate 621 and the second opening and closing plate 622 have the same structure. Only the structure of the first opening and closing plate 621 will be described here. A push plate 623 is provided at the end of the first opening and closing plate 621 away from the pre-storer 610. The push plate 623 is parallel to the first opening and closing plate 621 and extends in a direction away from the pre-storer hole 611. Pushing the push plate 623 upwards from below causes the first opening and closing plate 621 to rotate clockwise around the hinge point. The upper surface of the push plate 623... A baffle 624 is provided on the surface. The bottom end of the baffle 624 is connected to the push plate 623, and the top end is inclined towards the pre-storage device 610. A spring 625 is provided between the baffle 624 and the side wall of the pre-storage device 610. The spring 625 can provide a pushing force to the first opening and closing plate 621, so that the first opening and closing plate 621 always blocks the bottom of the pre-storage hole 611 without the use of external force. The seed potato will be pre-stored in the pre-storage device 610 to prepare for the next step of the seed potato.

[0037] The seeding assembly includes two parallel load-bearing rods 630, which are symmetrically arranged on both sides of the pre-storer 610. Figure 19 As shown, the load-bearing rod 630 includes a first support rod 631 and a second support rod 632. The first support rod 631 and the second support rod 632 are connected by a fixing rod 633, which is n-shaped. One end of the first support rod 631 away from the fixing rod 633 is fixedly connected to the frame 1, and the other end is fixedly connected to a first drive motor 634. One end of the second support rod 632 away from the fixing rod 633 is fixedly connected to a second drive motor 635. The output shafts of the first drive motor 634 and the second drive motor 635 are coaxially arranged.

[0038] A transmission disc 636 is fixedly connected to the output shaft of both the first drive motor 634 and the second drive motor 635. The transmission disc 636 is connected to the transmission rod 638 through a connecting rod 637. Specifically, one end of the connecting rod 637 is rotatably connected to the outer surface of the transmission disc 636 through a rotating shaft, and the other end is rotatably connected to the side wall of the transmission rod 638. Since the rotating shaft and the transmission disc 636 are eccentrically set, when the transmission disc 636 rotates, it can drive the transmission rod 638 to move up and down.

[0039] The transmission rod 638 and the load-bearing rod 630 are perpendicular to each other. The end of the transmission rod 638 away from the pre-storer 610 is slidably connected to the connecting rod 639. Specifically, a slide rod is provided at the end of the transmission rod 638 away from the pre-storer 610. A sliding hole is provided on the connecting rod 639. The sliding hole is opened along the length of the connecting rod 639 and is adapted to the slide rod. The slide rod can be inserted into the sliding hole, thereby realizing the sliding connection between the transmission rod 638 and the sliding hole.

[0040] The top end of the connecting rod 639 is hinged to the frame 1, thereby limiting and guiding the end of the transmission rod 638 when it moves up and down.

[0041] The end of the transmission rod 638 away from the connecting rod 639 is located at the bottom of the pre-store 610 and corresponds to the pre-store hole 611. The four transmission rods 638 on both sides of the pre-store 610 are staggered. That is, the two transmission rods 638 on the left side of the pre-store 610 correspond to the first pre-store hole 611 and the third pre-store hole 611 on the pre-store 610, respectively, and the two transmission rods 638 on the right side of the pre-store 610 correspond to the second pre-store hole 611 and the fourth pre-store hole 611 on the pre-store 610, respectively.

[0042] like Figure 20 As shown, the transmission rod 638 has a connecting part near the pre-storer 610. The connecting part is U-shaped and includes a horizontal rod 640 and a vertical rod 641. There are two vertical rods 641, which are arranged in parallel. The horizontal rod 640 connects the bottom ends of the two vertical rods 641. The distance between the two vertical rods 641 is equal to the distance between the two push plates 623. Each of the two vertical rods 641 is provided with a push block 642. When the transmission rod 638 moves upward under the drive of the transmission disc 636, the two push blocks 642 contact the two push plates 623 respectively and push the two push plates 623 upward, causing the first opening plate 621 and the second opening plate 622 to rotate around the hinge point, thereby opening the bottom of the pre-storer hole 611. The connecting part is provided with a mechanical claw and a pushing assembly. At this time, the mechanical claw is directly below the pre-storage hole 611. The seed potatoes stored in the pre-storage hole 611 fall from the bottom of the pre-storage hole 611 into the mechanical claw. The transmission disk 636 continues to rotate, and the mechanical claw moves to the bottom under the drive of the transmission rod 638. At this time, the push component controls the mechanical claw to open and close, so that the seed potatoes that have fallen into the mechanical claw fall from the bottom of the mechanical claw, realizing sowing and avoiding phenomena such as missed sowing, double sowing, and uneven plant spacing. When the innermost mechanical claw has completed sowing, the outermost mechanical claw has just completed receiving. As the sowing device moves forward, the outermost mechanical claw moves to the bottom and just continues the sowing position of the innermost mechanical claw, thereby realizing continuous sowing operation and effectively avoiding phenomena such as missed sowing, double sowing, and uneven plant spacing.

[0043] The mechanical claw includes a first claw hook 643 and a second claw hook 644. The first claw hook 643 and the second claw hook 644 are symmetrically arranged, and a receiving cavity capable of accommodating seed potatoes is formed between the first claw hook 643 and the second claw hook 644. The top ends of the first claw hook 643 and the second claw hook 644 are respectively rotatably connected to the vertical rod 641, thereby realizing the mutual opening and closing between the first claw hook 643 and the second claw hook 644.

[0044] The actuating assembly includes an electric push rod 645, which is disposed on the upper surface of the crossbar 640. A push rod 646 is hinged to the end of the electric push rod 645. The end of the push rod 646 away from the electric push rod 645 is connected to the first claw hook 643 and the second claw hook 644 via a first rocker arm 647 and a second rocker arm 648. Specifically, the end of the first rocker arm 647 away from the push rod 646 is hinged to the side wall of the first claw hook 643, and the end of the second rocker arm 648 away from the push rod 646 is hinged to the side wall of the second claw hook 644. A connecting hole is provided on the upper surface of the crossbar 640. The end of the push rod 646 away from the electric push rod 645 passes through the connecting hole and is rotatably connected to the first rocker arm 647 and the second rocker arm 648.

[0045] The electric push rod 645 extends, which can push the end of the first rocker 647 and the second rocker 648 connected to the push rod 646 downward through the push rod 646, so that the other ends of the first rocker 647 and the second rocker 648 move away from each other, thereby driving the first claw hook 643 and the second claw hook 644 to rotate around the hinge point respectively. The bottom of the mechanical claw opens, and the seed potato located in the receiving groove falls from the bottom of the mechanical claw to realize planting.

[0046] Because the four drive discs 636 are hinged to the connecting rod 637 at different positions, the four mechanical claws can open and close alternately, thereby achieving continuous sowing function.

[0047] A soil covering tray 8 is rotatably connected to the rear side of the frame 1. The soil covering tray 8 is located directly behind the seed metering mechanism 6 and is used to cover the soil after sowing to prevent the seeds from being exposed.

[0048] It is also equipped with a controller, which is a programmable controller. The controller is fixed on the frame 1 above the traveling mechanism 2. The controller is electrically connected to the first motor 209, the second motor 301, the third motor 401, the fourth motor 531, the first drive motor 634, the second drive motor 635 and the electric push rod 645, thereby controlling the seeder to complete the potato planting work.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
