Description

Technical Field

[0001] This invention relates to the field of potato sprouting technology, specifically to a potato sprouting planter and a planting method. Background Technology

[0002] Planting potatoes with the bud facing upwards is a key technique in potato cultivation, which helps improve potato quality and yield. Planting with the bud facing upwards ensures that the potato is planted with the bud facing upwards, which is conducive to bud germination, increases seedling emergence rate, reduces seed usage, and saves on seed. The correct bud direction also ensures that the potato rootstock develops downwards, resulting in a well-developed root system that is beneficial to increasing potato yield.

[0003] Existing potato planting techniques suffer from inconsistent bud orientation, resulting in a low bud alignment rate that negatively impacts later potato growth, development, and seedling uniformity, ultimately affecting harvest yield. Manual bud alignment is time-consuming and labor-intensive; therefore, there is an urgent need for a planter and planting method capable of automatically bud alignment during the planting process. Summary of the Invention

[0004] This invention provides a potato sprouting planter and a planting method. During the process of potato tubers falling from the seed box until the planting channel is completed, the invention can automatically adjust the orientation of the potato tuber buds by the coordinated operation of the rotating disc and the lifting seed protection bucket. Furthermore, the tilting bucket and the planting channel keep the adjusted potato tubers in the adjusted posture as they fall into the pre-opened trenches, so as to ensure the stability of the bud orientation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A potato sprouting planter, comprising:

[0007] Frame,

[0008] Potato seed boxes are installed on the vehicle frame;

[0009] A seed-discharging wheel is located below the outlet of the seed tuber box to receive the tubers inside the seed tuber box. The seed-discharging wheel can intermittently discharge tubers when it rotates.

[0010] The tilting bucket is driven to tilt and rotate. Inside the tilting bucket are a rotating disk and a lifting seed protector located outside the rotating disk. The rotating disk is positioned below the seed outlet to collect potato tubers that leak from the seed outlet wheel. When the rotating disk rotates, the orientation of the buds of the potato tubers on it can be adjusted. The lifting seed protector can rise above the rotating disk and limit the movement of the potato tubers on it. The lifting seed protector can also descend below the rotating disk so that when the tilting bucket tilts and rotates, the potato tubers on the rotating disk can slide down the disk surface.

[0011] The planting channel is located on the lower side of the tilting bucket. The inlet of the planting channel can receive the potato tubers that slide off the rotating plate, and the outlet of the planting channel can discharge the potato tubers into a pre-drilled trench.

[0012] Preferably, the seed-discharging wheel is installed on a turntable base below the potato seed box. A seed outlet is provided on the bottom plate of the turntable base. The seed-discharging wheel is driven by a first motor. The seed-discharging wheel is provided with multiple seed dropping holes. When the seed-discharging wheel is driven by the first motor to rotate, the potato pieces in the seed-discharging wheel can be discharged through one of the seed dropping holes and the seed outlet.

[0013] Preferably, the tilting bucket is equipped with a second electric push rod that is driven and connected to the lifting seed protection bucket. The second motor of the second electric push rod is used to drive the lifting seed protection bucket to move up and down. The tilting bucket is also equipped with a third motor located on the side of the second electric push rod. The output end of the third motor is connected to the rotating disk through a gear disk.

[0014] Preferably, a groove is welded to the side wall of the second electric push rod, and a first electric push rod is connected to the slider in the groove. The linear motion of the slider in the groove driven by the first electric push rod can be converted into the pitching and flipping motion of the tilting bucket.

[0015] As a preferred option, it also includes:

[0016] Frame,

[0017] The tow bar is fixed to the vehicle frame by a first pin;

[0018] A trencher, located at the front of the vehicle frame, is used to create trenches as the vehicle frame moves forward.

[0019] A soil-covering tray, located at the rear of the vehicle frame, is used to fill the trench with soil to cover the potato tubers, thereby completing the planting process.

[0020] Secondly, the present invention provides a planting method for a potato tuber sprouting planter, which is based on the aforementioned potato tuber sprouting planter, the planting method comprising:

[0021] Step S1: Pull the vehicle frame forward and open a trench using a trench opener while the vehicle frame is moving forward;

[0022] Step S2: The potato chunks in the potato chunk seed box fall onto the seed dispensing turntable, which rotates, and the potato chunks fall onto the turntable.

[0023] Step S3: Control the lifting seed protection bucket to fully rise in order to limit the potato chunks on the rotating plate to prevent them from falling;

[0024] Step S4: Obtain the position of the bud eyes of the potato tuber using a high-speed camera, and control the rotating disk to rotate according to the bud eye position until the bud eye position of the potato tuber faces the rear end of the frame.

[0025] Step S5: Lower the lifting seed protection bucket completely, and control the tilting bucket to tilt and tilt so that the potato tubers fall into the planting channel. The potato tubers slide down the planting channel into the pre-opened trench.

[0026] Step S6: Fill the trench with soil to cover the potato tubers, completing the positive sprouting planting.

[0027] Preferably, in step S4, if the bud of the potato tuber is located at the lower part of the tuber and is covered by the tuber itself, the lifting seed protection bucket is lowered to a preset height and at least half of the lifting seed protection bucket is kept above the rotating disk; then the flipping bucket is controlled to tilt and flip so that the potato tuber slides down and collides with the lifting seed protection bucket to flip so that the bud faces upward and falls into the planting channel.

[0028] Preferably, in step S5, when the tilting bucket tilts up and down, the angle between the plane of the rotating disk and the direction of gravity is less than a first preset angle; the formula for calculating the first preset angle is:

[0029] γ <arctan1 / μ;

[0030] In the formula, γ is the first preset angle, and μ is the coefficient of friction between the potato block and the rotating disk.

[0031] Preferably, the seed-discharging turntable is driven by a first motor, the lifting seed-protecting hopper is driven by a second electric push rod, the rotating disc is driven by a third motor, the tilting hopper is driven by a first electric push rod, and the high-speed camera, the first motor, the second electric push rod, the third motor, and the first electric push rod are all communicatively connected to a microcontroller.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. This invention first uses a seed-dispensing wheel to allow potato tubers to fall intermittently. Then, when the position of the bud can be determined, the rotation of the rotating disc and the lifting of the seed-protecting bucket are coordinated to adjust the orientation of the buds of the potato tubers to face the rear of the frame. The tilting bucket then allows the potato tubers with the adjusted posture to slide into the planting channel for planting. Finally, the tubers are planted with the corrected posture, resulting in a high degree of automation and stable quality of correct bud planting.

[0034] 2. When the location of the bud is obscured by the tuber itself and is difficult to determine, the present invention can also adjust the orientation of the bud by lowering part of the lifting seed protection bucket and flipping the flipping bucket, so that the tuber can adjust the orientation of the bud as it slides down and hits the lifting seed protection bucket, thereby ensuring that the bud can be corrected to a uniform posture and the bud can be planted in the correct position when the bud is in different orientations.

[0035] 3. Compared with existing technologies, this invention features a sprouting device in the middle of the potato planter frame for sprouting potato tubers. A high-speed camera captures images of the potato tubers falling onto the rotating disc, and the captured image information is transmitted to a microcontroller control box. The microcontroller control box performs image recognition on the captured tuber sprout information. After recognizing the sprout position information, it sends commands to the second motor, the third motor, and the first electric push rod based on the existing sprout position information. The second motor controls the raising and lowering of the seed-protecting bucket, and the third motor drives the rotating disc to rotate at a suitable angle. After the second and third motors complete their respective commands, the first electric push rod pushes the tilting bucket to rotate, causing the sprouted potato tubers to slide down. During the process of the tilting bucket tilting and causing the tubers to slide into the planting channel, the seed-protecting plate on the planting channel prevents the tubers from sliding outside the planting channel. The potato tuber sprouting and planting method provided by this invention, using a sprouting device to sprout potatoes before planting them in the soil, ensures a high sprouting rate, which helps to improve potato yield and quality.

[0045] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figure 1-6As shown, this embodiment provides a potato sprouting planter, which includes a frame 17. A pair of bearing seats 21 are fixed to the bottom of the frame 17 by nuts. A pair of first bearings 20 are fixed inside the bearing seats 21. A wheel axle 23 passes through the first bearings 20, and wheels 10 are mounted at both ends of the wheel axle 23. A potato tuber seed box 1 is mounted on the frame 17. A seed-discharging wheel 2 is provided below the outlet of the potato tuber seed box 1 to receive the potato tubers inside the seed box 1. The seed-discharging wheel 2 can intermittently discharge potato tubers when it rotates. It also includes a tilting bucket 13 that can be driven to tilt and rotate. The rotating bucket 13 is equipped with a rotating disk 30 and a lifting seed protection bucket 29 located outside the rotating disk 30. The rotating disk 30 is located below the seed outlet 40 to receive the potato tubers that leak out from the seed outlet wheel 2. When the rotating disk 30 rotates, the position of the bud eyes of the potato tubers on the rotating disk 30 can be adjusted. The lifting seed protection bucket 29 can be raised above the rotating disk 30 and limit the potato tubers on the rotating disk 30. The lifting seed protection bucket 29 can be lowered below the rotating disk 30 so that when the rotating bucket 13 tilts and flips, the potato tubers on the rotating disk 30 can slide down the disk surface.

[0048] The planting channel 4 is located on the side below the tilting bucket 13. The inlet of the planting channel 4 can receive the potato tubers that slide off the rotating disk 30, and the outlet of the planting channel 4 can discharge the potato tubers into a pre-drilled trench.

[0049] In this embodiment, the potato sprouting planter can intermittently drop potato tubers through the seed discharge wheel 2. Then, when the position of the bud eye can be determined, the rotation of the rotating disc 30 and the lifting and lowering of the seed guard hopper 29 are coordinated to adjust the orientation of the bud eye of the potato tuber to face the rear end of the frame 17. The tilting bucket 13 then slides the adjusted potato tuber into the planting channel 4, and finally completes the sprouting planting with a uniformly corrected posture. The planter has a high degree of automation and stable sprouting planting quality.

[0050] The seeder further includes: a traction rod 6 fixed to the frame 17 by a first pin 7; a furrow opener 9 located at the front of the frame 17, used to open furrows when the frame 17 moves forward; the furrow opener 9 is located at the front end of the frame 17 and includes a furrow opener 9 post 5 fixed to the frame 17 by a fastening pin 8, the furrow opener 9 being located inside the furrow opener 9 post 5; and a soil covering device located at the rear of the frame 17, the soil covering device including a soil covering mechanism 12, a soil covering disc 11, and a soil covering post 22, fixed to the rear end of the frame 17. The soil covering disc 11 is used to fill the furrows with soil to cover the potato tubers to complete the planting.

[0051] In one specific embodiment, the seed-discharging wheel 2 is installed on a turntable base 41 below the potato seed box 1. A seed outlet 40 is provided on the bottom plate of the turntable base 41. The seed-discharging wheel 2 is driven and connected to a first motor 16. The seed-discharging wheel 2 is provided with multiple seed dropping holes 39. When the seed-discharging wheel 2 is driven by the first motor 16 to rotate, the potato pieces in the seed-discharging wheel 2 can be discharged through one of the seed dropping holes 39 and the seed outlet 40.

[0052] In one specific embodiment, the first motor 16 is mounted on the frame 17 via a first fixing plate 35; a second electric push rod 26, which is driven and connected to the lifting seed protection hopper 29, is fixedly mounted on the tilting 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 hopper 29 to perform lifting and lowering movements; a rotating disk 30 is placed inside the lifting seed protection hopper 29; a second fixing plate 27 is welded onto the tilting bucket 13; a third motor 28 located on the side of the second electric push rod 26 is fixed to the second fixing plate 27 by a nut, and the output end of the third motor 28 is connected to the rotating disk 30 via a gear disk 34. The third motor 28 controls the rotation of the rotating disk 30 by driving the gear set 38 in the gear disk 34; the lifting seed protection hopper 29 has an opening on its side, and the gear disk 34 passes through the opening to connect to the rotating disk 30 placed inside the lifting seed protection hopper 29.

[0053] A groove 37 is welded to the side wall of the second electric push rod 26. A first electric push rod 15 is connected to the slider 36 in the groove 37. The linear motion of the slider 36 driven by the first electric push rod 15 in the groove 37 can be converted into the pitching and flipping motion of the tilting bucket 13.

[0054] There is a front baffle 14 in front of the tilting bucket 13, which acts as a hard limit to block the tilting bucket 13 when it resets; this allows the tilting bucket 13 to return to the predetermined position accurately.

[0055] In one specific embodiment, the location of the buds is acquired using a high-speed camera 31, and the rotation of the rotating disk 30, the lifting seed protection hopper 29, and the tilting hopper 13 is adjusted according to the location of the buds. A second fixing rod 32 is welded to 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 microcontroller. A first fixing rod 24 is welded to the middle of the frame 17, and the planting channel 4 is welded to the fixing rod. The planting channel 4 has an extended seed protection plate to prevent the potato tubers from falling out when the tilting hopper 13 rotates.

[0056] The control system in this embodiment includes an on-board battery 19 and a microcontroller control box 18 mounted on the frame 17. The microcontroller control box 18 can receive images of potato tubers captured by the high-speed camera 31 and analyze the position of the buds on the tubers. The microcontroller control box 18 is connected to the bud-aligning device via a connecting cable. If the high-speed camera 31 detects that the bud position of the potato tuber is facing the rear end of the frame 17, the first electric push rod 15 pushes the slider 36 to move in the slide groove 37, causing the tilting bucket 13 to rotate. At the same time, the lifting seed protection bucket 29 controlled by the second motor 25 descends to below the rotating disk 30. When the first electric push rod 15 pushes the tilting bucket 13 to rotate by a corresponding angle, it can be calculated that when the first electric push rod 15 pushes the tilting 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. Then the first electric push rod 15 stops working, and the potato tuber in the rotating disk 30 slides into the planting channel 4. When the potato tuber slides down, the bud position is above the ground, realizing bud-aligning planting.

[0057] If the high-speed camera 31 detects that the potato tuber's bud is facing away from the rear end of the frame 17, the microcontroller control box 18 sends a command to the third motor 28. The third motor 28 drives the gear set 38 in the gear disk 34 to rotate the rotating disk 30 by a corresponding angle, so that the potato tuber's bud is facing the rear end of the frame 17. After the bud is facing the rear end of the frame 17, the first electric push rod 15 pushes the slider 36 to move in the slide groove 37, causing the tilting bucket 13 to rotate. At the same time, the lifting seed protection bucket 29 controlled by the second motor 25 descends below the rotating disk 30. When the first electric push rod 15 pushes the tilting bucket 13 to rotate by a corresponding angle, the first electric push rod 15 stops working, and the potato tuber in the rotating disk 30 slides into the planting channel 4. When the potato tuber slides down, the bud is above the ground, achieving positive bud planting.

[0058] If the high-speed camera 31 does not collect information about the potato tuber buds, that is, the buds are covered by the potato tuber and the buds are located below the potato tuber, when the first electric push rod 15 pushes the tilting bucket 13 to rotate and the potato tuber falls, the lifting seed protection bucket 29 drops to 1 / 2 of its full height (this value is only a typical value and can also be other proportions). When the first electric push rod 15 pushes the tilting bucket 13 to rotate at the corresponding angle, the potato tuber in the rotating disk 30 will slide down and hit the lifting seed protection bucket 29, which has not fully dropped, and will flip over. After flipping, the position of the potato tuber buds is facing upward relative to the ground surface. The potato tuber falls in the planting channel 4 by gravity, achieving positive bud planting.

[0059] Example 2

[0060] Combination Figure 7 This embodiment provides a method for planting potatoes using a potato sprouting planter, which utilizes a potato sprouting planter as described in Embodiment 1. The planting method includes:

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

[0062] Step S2: The potato chunks in the seed box 1 fall onto the seeding turntable, which rotates, and the potato chunks fall onto the rotating disk 30. In a specific embodiment, the movement of the seeding turntable is controlled by a first motor 16. As the first motor 16 drives the seeding turntable to rotate, the potato chunks in the seed box 1 fall into the seeding hole 39 of the seeding turntable. When the potato chunks in the seeding hole 39 rotate to the seeding outlet 40 of the turntable base 41, the potato chunks fall onto the rotating disk 30 through the seeding channel 3 under the action of gravity.

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

[0064] Step S4: The high-speed camera 31 acquires the position of the potato tuber's bud eye, and controls the rotating disk 30 to rotate according to the bud eye position until the bud eye position of the potato tuber faces the rear end of the frame 17. In a specific embodiment, the high-speed camera 31 collects the bud eye position information of the potato tuber in the lifting seed protection bucket 29 and transmits it to the microcontroller control box 18. If it is detected that the bud eye position of the potato tuber faces 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 tilting bucket 13 to rotate. At the same time, the lifting seed protection bucket 29 controlled by the second motor 25 descends to below the rotating disk 30. When the first electric push rod 15 pushes the tilting bucket 13 to rotate at the corresponding angle, the first electric push rod 15 stops working, and the potato tuber in the rotating disk 30 slides into the planting channel 4. When the potato tuber slides down, the bud eye position is above the ground, realizing positive bud planting.

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

[0066] Step S5: Lower the lifting seed protection bucket 29 completely, and control the tilting bucket 13 to tilt and tilt so that the potato tubers fall into the planting channel 4. The potato tubers slide down the planting channel 4 into the pre-opened trench.

[0067] In step S5, when the tipping bucket 13 makes a pitching turnover, the angle between the plane of the rotating disk 30 and the direction of gravity is less than the 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 angle formed by 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>f1,

[0069] f1 = μF,

[0070] In the formula: f1 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联立公示得到γ<arctan1 / μ, finally it is obtained that when the 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 extra 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 sending these instructions, 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 plate 11 of the soil covering device then stirs the soil to bury the potato blocks, realizing the positive bud sowing of potato blocks.

[0072] Only some exemplary embodiments of the present invention have been described in the above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
