[0049] When the potato bud-forming seeder in this embodiment is in use, the seed wheel 2 can make the potato tubers fall intermittently, and then when the bud eye position can be determined, the rotation of the rotating disk 30 and the lifting and lowering movement of the lifting seed protection bucket 29 are coordinated to adjust the bud eye direction of the potato tubers to a state facing the rear end of the frame 17, and the potato tubers with adjusted posture are made to slide into the sowing channel 4 through the tipping bucket 13, and finally the bud-forming sowing is completed with a uniformly corrected posture, with a high degree of automation and stable bud-forming sowing quality.

[0050] The planter also includes: a traction rod 6 fixed to the frame 17 by a first latch 7; a furrow opener 9 provided in front of the frame 17, the furrow opener 9 is used to open a furrow when the frame 17 moves forward; the furrow opening device is placed at the front end of the frame 17, including a furrow opener 9 column 5 fixed to the frame 17 by a fastening latch 8, and the furrow opener 9 is arranged in the furrow opener 9 column 5; a soil covering device provided at the rear of the frame 17, the soil covering device includes a soil covering mechanism 12, a soil covering plate 11 and a soil covering column 22, and is fixed to the rear end of the frame 17. The soil covering plate 11 is used to fill soil in the furrow to cover the potato tubers to complete the sowing.

[0051] In a specific embodiment, the seed wheel 2 is installed on a turntable base 41 below the potato tuber seed box 1, and a seed outlet 40 is provided on the bottom plate of the turntable base 41. The seed wheel 2 is driven and connected to a first motor 16, and a plurality of seed holes 39 are provided on the seed wheel 2. When the seed wheel 2 is driven by the first motor 16 to rotate, the potato tubers in the seed wheel 2 can leak out through one of the seed holes 39 and the seed outlet 40.

[0052] In a specific embodiment, the first motor 16 is mounted on the vehicle frame 17 through a first fixing plate 35; a second electric push rod 26 drivingly connected to the lifting seed protection bucket 29 is fixedly mounted on the tipping bucket 13 by a nut; the second electric push rod 26 includes a push rod base 33 and a second motor 25; the second motor 25 of the second electric push rod 26 is used to drive the lifting seed protection bucket 29 to do lifting and lowering movements; a rotating disk 30 is placed inside the lifting seed protection bucket 29; a second fixing plate 27 is welded on the tipping bucket 13; a third motor 28 located on the side of the second electric push rod 26 is fixed on the second fixing plate 27 by a nut, and the output end of the third motor 28 is connected to the rotating disk 30 through a gear plate 34. The third motor 28 controls the rotation of the rotating disk 30 by driving the gear set 38 in the gear plate 34. The lifting seed protection bucket 29 has an opening on the side, and the gear plate 34 passes through the opening to connect the rotating disk 30 placed in the lifting seed protection bucket 29.

[0053] A slide groove 37 is welded on the side wall of the second electric push rod 26 , and the slider 36 in the slide groove 37 is connected to the first electric push rod 15 . The first electric push rod 15 drives the slider 36 to make a linear motion in the slide groove 37 which can be converted into a pitch and flip motion of the tipping bucket 13 .

[0054] A front baffle 14 is provided in front of the tipping bucket 13, which plays a hard limit role of blocking when the tipping bucket 13 is reset, so that the tipping bucket 13 can accurately return to the predetermined position.

[0055] In a specific embodiment, the embodiment obtains the position of the eye through a high-speed camera 31, and performs rotation adjustment of the rotating disk 30, the lifting seed protection bucket 29, and the turning bucket 13 according to the position of the eye. A second fixing rod 32 is welded on the frame 17, and the high-speed camera 31 is fixed to the second fixing rod 32 by a nut. The high-speed camera 31 can transmit the image of the potato tuber to the single-chip controller. A first fixing rod 24 is welded in the middle of the frame 17, and the sowing channel 4 is welded to the fixing rod. The sowing channel 4 has an extended seed protection plate to prevent the potato tubers from falling out when the turning bucket 13 rotates.

[0056] The control system in this embodiment includes a vehicle-mounted battery 19 and a single-chip control box 18 placed on the frame 17. The single-chip control box 18 can receive the potato tuber image taken by the high-speed camera 31 and analyze the bud eye position of the potato tuber. The single-chip control box 18 is connected to the bud correction device through a connecting line. If the high-speed camera 31 recognizes that the potato tuber bud eye position is toward the rear end of the frame 17, the first electric push rod 15 pushes the slider 36 to move in the slide groove 37, driving the tipping bucket 13 to rotate, and at the same time, the lifting and seed protection bucket 29 controlled by the second motor 25 descends to the bottom of the rotating disk 30. When the first electric push rod 15 pushes the tipping bucket 13 to rotate a corresponding angle, it can be calculated that when the first electric push rod 15 pushes the tipping bucket 13 to rotate until the angle γ between the rotating disk 30 and the vertical direction is less than 66.0°, the potato tuber can slide down smoothly, and then the first electric push rod 15 stops working, and the potato tuber in the rotating disk 30 slides into the sowing channel 4. When the potato tuber slides down, the bud eye position is above the land, realizing the positive bud sowing.

[0057] If the high-speed camera 31 recognizes that the position of the potato tuber eye is not toward the rear end of the frame 17, the single-chip control box 18 sends a command to the third motor 28, and the third motor 28 drives the gear set 38 in the gear plate 34 to drive the rotating disk 30 to rotate a corresponding angle, so that the potato tuber eye turns to a position toward the rear end of the frame 17. After the eye position is toward the rear end of the frame 17, the first electric push rod 15 is executed again to push the slider 36 to move in the slide groove 37, driving the tipping bucket 13 to rotate, and at the same time, the lifting and seed protection bucket 29 controlled by the second motor 25 descends to the bottom of the rotating disk 30. When the first electric push rod 15 pushes the tipping bucket 13 to rotate a corresponding angle, the first electric push rod 15 stops working, and the potato tubers in the rotating disk 30 slide into the sowing channel 4. When the potato tubers slide, the eye position is above the ground, realizing positive bud sowing.

[0058] If the high-speed camera 31 does not collect the information of the potato tuber eye, that is, the eye is covered by the potato tuber and is located below the potato tuber, then when the first electric push rod 15 pushes the tipping bucket 13 to rotate and make the potato tuber fall, the lifting and seed protection bucket 29 drops to 1 / 2 of the complete drop (this value is only a typical value and can also be other proportions). When the first electric push rod 15 pushes the tipping bucket 13 to rotate the corresponding angle, the potato tubers in the rotating disk 30 will slide down and hit the lifting and seed protection bucket 29 that has not fully dropped and will flip over. After the flip, the position of the potato tuber eye is facing upward compared to the ground surface, and the potato tubers fall by gravity in the sowing channel 4 to achieve positive bud sowing.

[0059] Example 2

[0060] Combination Figure 7 This embodiment provides a sowing method of a potato sprouting seeder, which is performed using a potato sprouting seeder in embodiment 1. The sowing method includes:

[0061] Step S1, use a tractor to pull the traction rod 6 in front of the frame 17, and use the first pin 7 to fix and pull the frame 17 forward, and use the trench opener 9 to open a trench when the frame 17 moves forward.

[0062] Step S2, the potato tubers in the potato tuber seed box 1 fall onto the seed turntable, the seed turntable rotates, and the potato tubers fall onto the rotating disk 30; in a specific embodiment, the movement of the seed turntable is controlled by the first motor 16, as the first motor 16 drives the seed turntable to rotate, the potato tubers in the potato tuber seed box 1 fall into the seed drop holes 39 of the seed turntable, and when the potato tubers in the seed drop holes 39 rotate to the seed outlet 40 of the turntable base 41, the potato tubers fall onto the rotating disk 30 from the seed drop channel 3 under the action of gravity.

[0063] Step S3, the single chip control box 18 controls the lifting seed protection bucket 29 to fully rise, so as to limit the potato pieces on the rotating disk 30 to prevent them from falling.

[0064] Step S4, obtaining the eye position of the potato tuber according to the high-speed camera 31, and controlling the rotation of the rotating disk 30 according to the eye position until the eye position of the potato tuber is toward the rear end of the frame 17; in a specific embodiment, the high-speed camera 31 collects the eye position information of the potato tuber in the lifting and seed protection bucket 29 and transmits it to the single-chip control box 18. If it is recognized that the eye position of the potato tuber is toward the rear end of the frame 17, the first electric push rod 15 pushes the slider 36 to move in the slide groove 37, driving the tipping bucket 13 to rotate, and at the same time, the lifting and seed protection bucket 29 controlled by the second motor 25 descends to the bottom of the rotating disk 30. When the first electric push rod 15 pushes the tipping bucket 13 to rotate a corresponding angle, the first electric push rod 15 stops working, and the potato tubers in the rotating disk 30 slide into the sowing channel 4. When the potato tubers slide down, the eye position is above the ground, realizing positive bud sowing.

[0065] In step S4, if the bud eye of the potato tuber is located at the bottom of the potato tuber and is covered by the potato tuber itself, the lifting and seed protection bucket 29 is lowered to a preset height and at least half of the lifting and seed protection bucket 29 is kept above the rotating disk 30; then the tipping bucket 13 is controlled to pitch and flip, so that the potato tuber slides and collides with the lifting and seed protection bucket 29 to flip to the bud eye facing upward and fall into the sowing channel 4.

[0066] Step S5, the lifting seed protection bucket 29 is completely lowered, and the tipping bucket 13 is controlled to pitch and tip to drop the potato pieces into the sowing channel 4, and the potato pieces slide along the sowing channel 4 into the pre-opened channel;

[0067] In step S5, when the tipping bucket 13 makes a pitching turnover, the included angle between the plane of the rotating disk 30 and the direction of gravity is less than a first preset angle; the calculation method of the first preset angle is as follows: F is the upward supporting force of the potato on the rotating disk 30, γ is the included angle between the self-gravity mg of the potato block and the plane of the rotating disk 30. For the potato block to slide down smoothly, the following conditions need to be met:

[0068] mgfcosγ>f 1 ,

[0069] f 1 =μF,

[0070] In the formula: f 1 is the frictional force generated by the potato block and the plate surface when sliding occurs; μ is the friction coefficient between the potato block and the rotating disk 30. The friction coefficient between the potato block and the rotating disk 30 is measured to be 0.269 - 0.445. By联立 the formula, γ < arctan1 / μ is obtained. Finally, it is concluded that when the included angle γ between the rotating disk and the vertical direction is less than 66.0°, the potato block can slide down smoothly.

[0071] In summary, the working principle of this embodiment is as follows: Pour the potato blocks into the potato block seed box 1. The potato blocks fall out of the seed box and are distributed in the seed dropping holes 39 of the seed discharging wheel disk 2. The first motor 16 drives the seed discharging wheel disk 2 to rotate. During the rotation to the seed discharging port 40, the side plate of the potato block seed box 1 scrapes off the excess potato blocks above the potato blocks in the seed dropping holes 39, so that only one potato block remains in the seed dropping holes 39. When rotating to the seed discharging port 40 of the wheel disk base, the potato blocks in the seed dropping holes 39 fall from the seed discharging channel 3 into the rotating disk 30. The high-speed camera 31 takes the image information of the potato blocks in the rotating disk 30 and uploads it to the single-chip microcomputer control box 18. The single-chip microcomputer control box 18 identifies the position information of the bud eyes of the potato blocks and sends instructions to the second motor 25 and the third motor 28, so that the rotating disk 30 and the lifting seed protecting bucket 29 respectively driven and controlled by the third motor 28 and the second motor 25 make corresponding rotation angles and appropriate lifting heights, so that the bud eyes of the potato blocks face the correct positions. After these instructions are completed, the single-chip microcomputer control box 18 sends an instruction to the first electric push rod 15 to push the tipping bucket 13 to rotate. The potato blocks slide into the sowing channel 4 during the rotation of the tipping bucket 13. The bud eyes of the potato blocks falling from the sowing channel 4 into the ditch opened by the furrow opener 9 are upward relative to the land. The soil covering disk 11 of the soil covering device then stirs the soil to bury the potato blocks, realizing the positive bud sowing of the potato blocks.
