In this way, the buckwheat planter can also realize the irrigation function.

[0083] For further information, see Figure 1 As shown, the buckwheat seeder also includes a solar power supply component 70 installed on the frame 11, wherein the solar power supply component 70 includes a damping frame 71, a solar panel 72 and a control module 73, the damping frame 71 is vertically connected to the frame 11, the solar panel 72 is rotatably connected to the top of the damping frame 71, and the control module 73 is located at the bottom of the damping frame 71, and the control module 73 is electrically connected to the solar panel 72, the first drive motor 13, the transmission component 21, the second drive motor 221, the double disc opener 32, the third drive motor 41 and the motor pressure pump 63 respectively.

[0084] In some embodiments of the present invention, the solar panel 72 absorbs sunlight through the photoelectric effect, converts solar energy into electrical energy and stores it in a lithium battery. The damping frame 71 can adjust the angle of the solar panel 72 to fully absorb sunlight for photoelectric conversion. After the solar panel 72 is powered, the switch is pressed and the machine works. After the motor pressure pump 63 is pressurized, water is sprayed out through the sprayer 64 to cover the planting land. The control module 73 is composed of a single-chip microcomputer, a step-down module, an L298N motor drive module, photoelectric, ultrasonic sensors, a servo, a Bluetooth module and multiple functional switches.

[0085] Working process:

[0086] When it is necessary to sow buckwheat intelligently, the solar panel 72 absorbs sunlight through the photoelectric effect, converts solar energy into electrical energy and stores it in the lithium battery. After the solar panel 72 supplies power, the switch is pressed and the machine starts working.

[0087] First, the land is reclaimed and trenched. The double disc trencher 32 rolls forward to dig trenches and push the soil away. Then, the double disc trencher 32 pushes toward both sides to form a seed trench during its movement.

[0088] Secondly, seeding is carried out in the dug seed furrow, and the third driving motor 41 is started. The third driving motor 41 drives the third rotating shaft 441 to rotate. When the third rotating shaft 441 rotates, it drives the shaft sleeve 442 to rotate. When the shaft sleeve 442 rotates, it drives the seeding disk 443 to rotate. When the seeding disk 443 rotates, it drives the seeding spoon 444 to rotate. As the seeding disk 443 rotates, the seeds in the seeding box 445 close to the seeding spoon 444 are filled into the spoon. When the seeding disk 443 moves to the top, the seeds in the seeding spoon 444 enter the double disc furrow opener 32 through the seeding tube 446 under the action of gravity and fall into the soil. The seeding spoon 444 is designed with a fitting groove according to the appearance characteristics of buckwheat seeds, so that the seeds can adhere to the spoon. The seeding disk 443 can adjust the speed of the third driving motor 41 to control the speed of the seeding disk 443, so as to adjust the sowing amount and achieve uniform and accurate sowing.

[0089] Then, the fertilization work begins. The third drive motor 41 drives the third rotating shaft 441 to rotate. When the third rotating shaft 441 rotates, it drives the large toothed disc 5111 to rotate. When the large toothed disc 5111 rotates, it drives the double toothed disc 5113 to rotate through the first chain 5112. When the double toothed disc 5113 rotates, it drives the stirring shaft 532 to rotate. When the stirring shaft 532 rotates, it drives the agitator 533 to stir the fertilizer inside the fertilizer storage box 531 evenly. At the same time, when the double toothed disc 5113 rotates, it drives the small toothed disc 5122 to rotate. When the small toothed disc 5122 rotates, it drives the fourth rotating shaft 522 to rotate. When the fourth rotating shaft 522 rotates, it drives the groove wheel 523 to rotate. After being stirred, the fertilizer falls through the fertilizer outlet 5311, and is then discharged from the inside of the fertilizer storage box 531 and sprinkled into the soil through the rotation of the groove wheel 523.

[0090] Finally, the soil is compacted after sowing and fertilizing by rotating the manual handle 214, which drives the first rotating shaft 212 to rotate, and the first rotating shaft 212 drives the first bevel gear 213 to rotate when it rotates, and the first bevel gear 213 drives the second bevel gear 223 to rotate when it rotates, and the second bevel gear 223 drives the threaded shaft 222 to rise and fall when it moves up and down, and the connecting frame 231 drives the pressing wheel 234 to rise and fall when it moves up and down, so as to achieve the height adjustment of the pressing wheel 234; when the pressing wheel 234 is moved up and down, the connecting frame 231 drives the pressing wheel 234 to rise and fall, and the height adjustment of the pressing wheel 234 is achieved; when the pressing wheel 234 is moved up and down, the connecting frame 231 drives the pressing wheel 234 to rise and fall, and the connecting frame 231 drives the pressing wheel 234 to rise and fall, and the connecting frame 231 drives the pressing wheel 234 to rise and fall, so as to achieve the height adjustment of the pressing wheel 234; when the pressing wheel 234 is moved up and down, the connecting frame 231 drives the connecting frame 231 to move up and down, and ... After 234 passes the land with trenches opened and planted in front, it can level the land so that the soil and seeds are in close contact. Through rolling compaction and vibration, the soil blocks are crushed, the cultivated layer is compacted, and the land is leveled, which has a good moisture retention effect, so that the seedlings are all in place and strong. At this time, the motor pressure pump 63 is started. After the motor pressure pump 63 is pressurized, the water source is sprayed out through the sprayer 64 to cover the planted land. By using four first drive motors 13 to drive the corresponding moving wheels 12 respectively to perform four-wheel drive, the structure is simpler, the transmission efficiency is higher, and the power loss in the transmission process is reduced. The four wheels can adjust the speed separately to realize the functions of turning and moving forward more easily. The power is distributed directly by controlling the two first drive motors 13 of the front and rear axles. The response speed is faster and more accurate. According to the real-time adhesion of the four wheels and the road conditions, the power and torque of the four wheels can be reasonably distributed in time, and it can adapt to various complex terrains.
