[0033] In this device, the connecting mechanism 2 is used to connect to the agricultural traction device, the trenching mechanism is used to dig trenches on the ground, and the trenching is convenient for planting peanuts. The fertilizer box 3 is used to load fertilizer. The fertilizer used in this embodiment is solid granular fertilizer. The top of the fertilizer box 3 is open. The fertilizer discharge mechanism is used to discharge the fertilizer in the fertilizer box 3. The fertilizer discharge mechanism discharges the fertilizer into the first discharge pipe 4, and the fertilizer falls into the dug trench through the first discharge pipe 4. The seed box 5 is used to load peanut seeds. The seed discharge mechanism is used to discharge peanut seeds. The seed discharge mechanism can select different seed discharge speeds to achieve different sowing densities. The first motor 10 drives the first rotating shaft 7 to rotate. The first rotating shaft 7 drives the seed discharge mechanism to operate. The seeds discharged by the seed discharge mechanism enter the second discharge pipe 9 and fall into the dug trench through the second discharge pipe 9. The soil covering mechanism buries the trench and seeds, thereby completing the sowing work. The shell 6 is fixedly connected to the frame 1 through a reinforcing plate.

The first seeding disc 11 is provided with a plurality of first grooves 14, the second seeding disc 12 is provided with a plurality of second grooves 15, and the third seeding disc 13 is provided with a plurality of third grooves 16. The numbers of the first grooves 14, the second grooves 15 and the third grooves 16 are different. The first seeding disc 11, the second seeding disc 12 and the third seeding disc 13 are detachably connected to the first rotating shaft 7, the first seeding disc 11 and the second seeding disc 12 are fixedly connected, the second seeding disc 12 and the third seeding disc 13 are fixedly connected, a first pulley 17 is fixedly connected to the output shaft of the first motor 10, a second pulley 18 is fixedly connected to the first rotating shaft 7, and the first pulley 17 and the second pulley 18 are connected via a belt 19.

[0035] The first, second, and third seed-row discs 11, 12, and 13 are located within the housing 6 and rotate simultaneously under the drive of the first rotating shaft 7. One of the first, second, and third seed-row discs 11, 12, 13 corresponds to the first feed port and the third discharge port on the housing 6. For example, when the first seed-row disc 11 corresponds to the first feed port and the third discharge port, the first groove 14 can receive peanut seeds from the first feed port. The first groove 14 rotates with the peanut seeds. When the first groove 14 rotates to the third discharge port, the peanut seeds fall from the first groove 14 and enter the second discharge pipe 9. When the planting density needs to be adjusted, the second or third seed-row disc 12, 13 can be replaced. In this embodiment, there are four first grooves 14, six second grooves 15, and eight third grooves 16.

[0036] To further optimize the solution, a first through hole is provided on the first seed row disc 11, the second seed row disc 12 and the third seed row disc 13, a sleeve 20 is fixedly connected in the first through hole, a plurality of ridges 21 are fixedly connected to the first rotating shaft 7, the plurality of ridges 21 are arranged in a circle on the outer edge of the first rotating shaft 7, a plurality of slots are provided on the inner edge of the sleeve 20, the ridges 21 are inserted into the slots, and a positioning mechanism is provided between the sleeve 20 and the first rotating shaft 7.

[0037] The setting of the first rotating shaft 7 and the convex strip 21 is similar to a spline shaft. The sleeve 20 can slide on the first rotating shaft 7. The two ends of the sleeve 20 are completely extended from the two ends of the shell 6. When the planting density needs to be adjusted, the positioning mechanism is opened and the sleeve 20 is moved to move the first row seed disc 11, the second row seed disc 12 and the third row seed disc 13 inside the shell 6. When the position is selected, the positioning mechanism is fixed.

[0038] A further optimized solution is that the positioning mechanism includes a plurality of positioning screws 22, through holes are provided at both ends of the sleeve 20, a plurality of first threaded holes 23 are provided on the first rotating shaft 7, the internal threads of the first threaded holes 23 are connected to the positioning screws 22, and the positioning screws 22 pass through the through holes.

[0039] The through hole on the sleeve 20 is used to pass the positioning screw 22 . After the positioning screw 22 is tightened, the sleeve 20 can be locked on the first rotating shaft 7 .

[0040] Further optimization scheme, the fertilizer discharge mechanism includes a second motor 24 and a spiral blade 25, the second motor 24 is arranged on the frame 1, and a second through hole is opened on the first discharge pipe 4, and a positioning tube 26 is fixedly connected in the second through hole. A second rotating shaft 27 is passed through the positioning tube 26, and the second rotating shaft 27 is rotatably connected in the positioning tube 26 through a bearing. The second rotating shaft 27 extends into the first discharge pipe 4, and the spiral blade 25 is fixedly connected to the second rotating shaft 27. A first bevel gear 28 is fixedly connected to the second rotating shaft 27, and a second bevel gear 29 is fixedly connected to the output shaft of the second motor 24, and the first bevel gear 28 is meshed with the second bevel gear 29.

[0041] When it is necessary to discharge fertilizer, the second motor 24 is started, and the second motor 24 drives the second bevel gear 29 to rotate, and the second bevel gear 29 drives the first bevel gear 28 to rotate, and the first bevel gear 28 drives the second rotating shaft 27 to rotate. The second rotating shaft 27 and the spiral blade 25 rotate at the same time. The rotation of the spiral blade 25 will push the fertilizer in the first discharge pipe 4 downward, thereby realizing the discharge of the fertilizer. When it is not necessary to discharge the fertilizer, the rotation of the second motor 24 can be stopped.

[0042] A further optimized solution is provided, in which the trenching mechanism includes a trencher 33. A first fixed frame 30 is fixedly connected to the bottom surface of the frame 1. A rectangular tube 31 is fixedly connected to the first fixed frame 30. A rectangular rod 32 is inserted into the rectangular tube 31. The rectangular rod 32 is movably arranged in the rectangular tube 31. The trencher 33 is fixedly connected to the lower end of the rectangular rod 32. A second threaded hole is provided on the rectangular rod 32. A fixed plate 34 is fixedly connected to the frame 1. A third through hole is provided on the fixed plate 34. A cavity is provided in the fixed plate 34, which is connected to the third through hole. A driving rod 35 is passed through the third through hole.

The driving rod 35 is threaded in the second threaded hole. A handwheel 37 is fixedly connected to the top of the driving rod 35.

[0043] Under the traction of the agricultural traction equipment, the frame 1 will move, and the furrow opener 33 will enter the soil. When the frame 1 moves, furrowing can be achieved; the rectangular rod 32 can move up and down in the rectangular tube 31. When the hand wheel 37 is turned, the driving rod 35 drives the limit block 36 to rotate, and the driving rod 35 will not move up and down; when the furrowing depth needs to be adjusted, the hand wheel 37 is turned by hand, and the hand wheel 37 drives the driving rod 35 to rotate. The driving rod 35 is threadedly connected to the rectangular rod 32. The rotation of the driving rod 35 will cause the rectangular rod 32 to rise or fall, thereby achieving the adjustment of the furrowing depth.

[0044] A further optimized solution is that a first connecting rod 38 is fixedly connected to the frame 1, a first connecting plate 39 is fixedly connected to the bottom end of the first connecting rod 38, a third motor 40 is fixedly connected to the first connecting plate 39, a fourth through hole is provided on the first connecting plate 39, the first discharge pipe 4 is connected to the fourth through hole, an annular retaining ring 41 is fixedly connected to the bottom surface of the first connecting plate 39, the output shaft of the third motor 40 passes through the first connecting plate 39, and a plurality of shifting rods 42 are fixedly connected to the output shaft of the third motor 40, and the shifting rods 42 are located in the annular retaining ring 41.

[0045] When the fertilizer in the first discharge pipe 4 comes out, it may be relatively concentrated. If the fertilizer accumulates on the seeds, it may cause seedling burns. The third motor 40 drives the lever 42 to rotate. When the fertilizer falls from the first discharge pipe 4, the lever 42 will scatter the fertilizer, thereby avoiding seedling burns. The annular retaining ring 41 can prevent the fertilizer from being too dispersed.

[0046] According to a further optimized solution, a plurality of second connecting rods 43 are fixedly connected to the frame 1 , a covering plate 44 is fixedly connected to the second connecting rods 43 , two support plates 45 are fixedly connected to the frame 1 , and support wheels 46 are rotatably connected to the support plates 45 .

[0047] The support wheels 46 are used to support the frame 1 so that the device can maintain a stable height during movement.

[0048] A further optimized solution is that the covering mechanism includes several covering plates 44, two second connecting plates 47 are fixedly connected to the frame 1, a third connecting plate 48 is rotatably connected to the second connecting plate 47, a third rotating shaft 49 is rotatably connected between the two third connecting plates 48, several rolling wheels 50 are fixedly connected to the third rotating shaft 49, and an electric telescopic rod 51 is movably connected between the third connecting plate 48 and the frame 1.

[0049] The covering plate 44 pushes the soil into the trench to bury the seeds in the trench. The second connecting plate 47 and the third connecting plate 48 are used to install the third rotating shaft 49. The rolling wheel 50 is used to compact the soil on the trench. The electric telescopic rod 51 can adjust the angle of the third connecting plate 48, thereby adjusting the pressure of the rolling wheel 50 on the ground.

[0050] According to a further optimized solution, the fertilizer box 3 is fixedly connected to the frame 1 via a second fixing frame 52 , and the seed box 5 is fixedly connected to the frame 1 via a third fixing frame 53 .

[0051] The working principle of this device is that when in use, the connecting mechanism 2 is connected to the agricultural traction device, and the support wheel 46 allows the device to maintain a stable height during movement. The hand wheel 37 is turned, and the hand wheel 37 drives the driving rod 35 to rotate. The driving rod 35 is threadedly connected to the rectangular rod 32. The rotation of the driving rod 35 causes the rectangular rod 32 to rise or fall, thereby adjusting the trenching depth;

[0052] Fertilizer is poured into the fertilizer box 3, and seeds are poured into the seed box 5. The device moves under the traction of the agricultural traction device. When discharging fertilizer, the second motor 24 is started, and the second motor 24 drives the second bevel gear 29 to rotate. The second bevel gear 29 drives the first bevel gear 28 to rotate. The first bevel gear 28 drives the second rotating shaft 27 to rotate. The second rotating shaft 27 and the spiral blade 25 rotate at the same time. The rotation of the spiral blade 25 pushes the fertilizer in the first discharge pipe 4 downward. When the fertilizer in the first discharge pipe 4 comes out, the third motor 40 drives the lever 42 to rotate. The lever 42 will scatter the fertilizer to prevent the fertilizer from agglomerating.

[0053] When discharging seeds, the first motor 10 drives the first pulley 17 to rotate, the first pulley 17 drives the second pulley 18 to rotate through the belt 19, and the second pulley 18 drives the first rotating shaft 7 to rotate. Under the drive of the first rotating shaft 7, one of the first groove 14, the second groove 15 and the third groove 16 moves the seeds from the first feed port to the third discharge port, and the seeds enter the second discharge pipe 9 and are discharged from the second discharge pipe 9 into the ditch. The covering plate 44 pushes the soil into the ditch to bury the seeds in the ditch, thereby completing the seeding.

[0054] When the planting density needs to be adjusted, unscrew the positioning screw 22 and move the sleeve 20 on the first rotating shaft 7 to move the first seed row disc 11, the second seed row disc 12 and the third seed row disc 13 inside the housing 6, thereby changing the positions of the first groove 14, the second groove 15 and the third groove 16. After the position is selected, tighten the positioning screw 22 again.
