Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Embodiment

[0027] Refer to Figures 1-3 , a high-performance intelligent precision fertilizing and seeding machine, including a mixing box 1 and a cylinder 4. The mixing box 1 is fixed at the upper outer side of the cylinder 4, and the cylinder 4 is fixed on the suspension at the tail of the seeding machine through a lift.

[0028] A connecting pipe 6 is rotatably arranged on the axis of the cylinder 4. The upper end of the connecting pipe 6 is provided with a seeding assembly. The lower end of the connecting pipe 6 penetrates through the cylinder 4 and extends to the lower outer side of the cylinder 4. A spiral soil-breaking blade 17 is arranged at the outer bottom position of the connecting pipe 6. Refer to Figure 6 , the mixing box 1 is fixedly arranged around the cylinder 4 in a surrounding manner, and the bottom of the mixing box 1 is inclined downward towards the cylinder 4. The bottom of the mixing box 1 is communicated with the inside of the cylinder 4 through a material leakage hole 7. Sandy soil particles are filled in the mixing box 1 in advance.

[0029] The seeding assembly includes a blanking assembly, a first support frame 21, a second support frame 22 and an electric telescopic rod 28. The first support frame 21 is symmetrically installed at the top of the cylinder 4, and the blanking assembly is located between the two first support frames 21. The second support frame 22 is installed at the top of the cylinder 4. The electric telescopic rod 28 is installed on one side of the second support frame 22, and the other end of the electric telescopic rod 28 penetrates through one of the first support frames 21 and extends to the other side of the first support frame 21.

[0030] Refer to Figure 7 and Figure 3The feeding assembly includes a first pipe 19, a second pipe 20, a seed feed bin 18, a slide bar assembly 23, bristles 24 and a second motor 29. The first pipe 19 and the second pipe 20 are respectively installed on one side of the two first support frames 21. A gap is arranged between the ends of the first pipe 19 and the second pipe 20. Bristles 24 are arranged at the end positions of the first pipe 19 and the second pipe 20. The slide bar assembly 23 is slidably arranged between the first pipe 19 and the second pipe 20. The second motor 29 is located on the inner side of the second pipe 20. The slide bar assembly 23 is connected to the output shaft of the second motor 29. A seed feed bin 18 is arranged between the outer sides of the ends of the first pipe 19 and the second pipe 20.

[0031] The slide bar assembly 23 is connected by multiple rods with different diameters, and the diameter of the rods decreases from left to right. When the slide bar assembly 23 moves between the ends of the first pipe 19 and the second pipe 20, it contacts the bristles 24. A funnel 25 is installed on the upper part of the connecting pipe 6, and the funnel 25 is located below the slide bar assembly 23.

[0032] The cylinder 4 is connected by a lifting mechanism at the rear of the agricultural vehicle. When sowing on soil with a high clay content, the gaps between clay particles are small, and the ventilation and water permeability are poor, which easily leads to water accumulation in the soil. However, ordinary sand is thrown on soil with a high clay content, and the soil improvement effect is not obvious.

[0033] For this reason, when sowing on soil with a large amount of clay, it is necessary to fill the interior of the mixing box 1 with sand and soil. After the cylinder 4 is adjusted to a suitable height, it is moved with the traction of the agricultural vehicle, and the soil-breaking blades 17 at the lower end push away the soil on the soil surface, and the lower end part of the soil-breaking blades 17 extends into the soil. In this process, the sand and soil in the mixing box 1 is tilted at the bottom of the mixing box 1, and the sand and soil are granular and have strong rolling properties. The sand and soil falls along the leakage hole 7, and then falls from the through hole 15 at the bottom of the cylinder 4. The fallen sand and soil enters the channel pushed away by the soil-breaking blades 17 to mix with the soil in the lower layer, avoiding the problem of sand and soil only appearing on the soil surface. When sowing, since the upper and lower ends of the connecting pipe 6 are both opened, the fallen seeds will fall from the bottom of the connecting pipe 6, and the lower end of the connecting pipe 6 is connected to the upper end of the soil-breaking blades 17, and the bottom of the connecting pipe 6 is still a distance from the ground, so that the problem of soil adhesion will not be caused during the rotation of the connecting pipe 6, thereby ensuring the smooth feeding of seeds.

[0034] Existing seeders can accurately control the number of seeds sown at a time when feeding seeds. However, for different seeds, the particle diameters of the seeds may be different, generally ranging from 0.3 to 12 mm, which is a large difference. As a result, when seeds of different sizes need to be sown, the feeding structure needs to be replaced and reassembled.

[0035] Therefore, a first pipe 19 and a second pipe 20 are respectively fixed on opposite sides of two first support frames 21. A sliding rod assembly 23 capable of sliding inside the two pipes is arranged between the first pipe 19 and the second pipe 20. The sliding rod assembly 23 is connected by multiple rods with different diameters, and the diameters of the rods decrease from left to right. When seeds enter the seed feed bin 18 from the seed box, the second motor 29 drives the sliding rod assembly 23 to rotate. Since the diameter of the sliding rod assembly 23 is smaller than the diameters of the first pipe 19 and the second pipe 20, the seeds will fall on the upper surface of the sliding rod assembly 23. When the sliding rod assembly 23 rotates, the seeds can be smoothly transferred to the lower end. The number of seeds sown each time is within the moving range, thus realizing sowing smoothly. This structure is a common setting of the seed feeding box in the prior art. The improvement lies in that the second motor 29 adjusts its position through an electric telescopic rod 28 inside the second pipe 20, enabling the sliding rod assembly 23 to move between the first pipe 19 and the second pipe 20 while rotating. During the movement, rods with different diameter sizes on the sliding rod assembly 23 will move above the funnel 25. When the diameter of the rod on the sliding rod assembly 23 changes to adapt to the sowing of seeds of different sizes. For example, when the diameter of the rod increases, the pipe diameter difference between the rod and the first pipe 19 and the second pipe 20 becomes smaller, and the space for accommodating the passing seeds also becomes smaller, which is suitable for small-grained seeds. When the diameter of the rod decreases, the pipe diameter difference between the rod and the first pipe 19 and the second pipe 20 becomes larger, and the space for accommodating the passing seeds also becomes larger, which is suitable for large-grained seeds. Thus, according to the diameter of the seeds to be sown, the problem can be solved by controlling the electric telescopic rod 28 to drive the sliding rod assembly 23 to adjust its position.

[0036] The function of the bristles 24 is that when the diameter of the rod on the sliding rod assembly 23 is adjusted, the bristles 24 block the end positions of the first pipe 19 and the second pipe 20 to prevent seeds from entering through the gaps between the rod and the first pipe 19 and the second pipe 20.

[0037] Example 2, refer to Figures 4-5 , the difference between this embodiment and Embodiment 1 is that a first motor 5 is installed at the top of the cylinder body 4, an annular track 27 is arranged inside the cylinder body 4, a cushion block 26 is slidably arranged inside the annular track 27, a toothed disc 10 is connected between multiple cushion blocks 26, a plurality of baffle plates 11 are evenly installed at the lower end of the toothed disc 10, the positions of the baffle plates 11 match the positions of the material leakage holes 7, and the baffle plates 11 are in mutual fit with the inner wall of the cylinder body 4. A transmission component is arranged between the toothed disc 10 and the output shaft of the first motor 5.

[0038] The transmission assembly includes a first transmission gear 8 and a second transmission gear 9. The first transmission gear 8 is fixedly installed at the end of the output shaft of the first motor 5. The second transmission gear 9 is installed on the outer side of the connecting pipe 6. The first transmission gear 8 is located inside the toothed disc 10, and the first transmission gear 8 meshes with the second transmission gear 9 and the toothed disc 10 respectively. A plurality of through holes 15 are distributed in an annular array at the bottom of the cylinder body 4. The plurality of through holes 15 are located near the edge of the cylinder body 4. The upper end of the connecting pipe 6 is installed with a connecting rod 12. A straight plate 13 is hinged at the bottom of the connecting rod 12. The position of the straight plate 13 matches the position of the through hole 15.

[0039] Reference Figure 8 , scraping teeth 14 are uniformly arranged at the bottom of the straight plate 13. The scraping teeth 14 are in contact with the bottom of the cylinder body 4. A conical surface 16 is arranged at the bottom of the cylinder body 4.

[0040] When the sandy soil leaks out from the through holes 15 and enters the soil with a higher clay content, it is necessary to accurately control the throwing amount of the sandy soil to ensure that the sandy soil thrown in each area is more uniform, and at the same time avoid the problem of accumulation in the cylinder body 4.

[0041] Therefore, a second transmission gear 9 is arranged on the connecting pipe 6. The first transmission gear 8 is installed at the end of the output shaft of the first motor 5. The first transmission gear 8 transmits kinetic energy to the second transmission gear 9 and the toothed disc 10, driving the connecting pipe 6 to rotate. At the same time, a groove is presented on the upper part of the toothed disc 10 for accommodating the second transmission gear 9 and the first transmission gear 8, and the cylinder body 4 is divided into two parts by the toothed disc 10, ensuring that the leakage hole 7 is located below the toothed disc 10, and the sandy soil will not contact the first transmission gear 8 and the second transmission gear 9. When the toothed disc 10 rotates, the external cushion block 26 will slide in the annular track 27, playing a supporting role for the toothed disc 10. When the sandy soil particles leak out from the leakage hole 7, since the toothed disc 10 is always in the process of rotation, the baffle 11 connected to the lower end of the toothed disc 10 will intermittently block the leakage hole 7, so that the sandy soil particles falling within a unit time are maintained within a stable range. A conical surface 16 is arranged at the center position of the bottom of the cylinder body 4, and the sandy soil will roll down from the conical surface 16 to the edge position of the cylinder body 4. At this time, a plurality of connecting rods 12 are installed outside the connecting pipe 6. A straight plate 13 is hinged at the bottom of the connecting rod 12. At the same time, scraping teeth 14 are arranged at the bottom of the straight plate 13. During the rotation of the straight plate 13, the falling sandy soil can be pushed out from the through holes 15, ensuring that the sandy soil evenly falls on the soil.

[0042] The working principle of this device is as follows: The cylinder body 4 is connected by a lifting mechanism at the rear of the agricultural vehicle. When sowing on the soil with a higher clay content, the gaps between clay particles are small, the air permeability and water permeability are poor, and it is easy to cause waterlogging in the soil. And when the sandy soil is directly thrown on the surface of the soil with a higher clay content, the improvement effect of the soil is not obvious.

[0043] Therefore, when sowing on soil with a large amount of clay, it is necessary to fill the inside of the mixing box 1 with sandy soil. After the cylinder body 4 is adjusted to an appropriate height, it moves along with the traction of the agricultural vehicle. The soil-breaking blades 17 at the lower end push aside the soil on the soil surface, and the soil-breaking blades 17 achieve the effect of opening a trench, which can be replaced by a ditching tool. During this process, since the bottom of the mixing box 1 is inclined and the sandy soil is granular with strong rolling properties, the sandy soil falls through the material leakage holes 7 and then falls from the through holes 15 at the bottom of the cylinder body 4. The fallen sandy soil enters the channel pushed aside by the soil-breaking blades 17 to mix with the lower-layer soil, avoiding the problem that the sandy soil only appears on the soil surface. During sowing, since both the upper and lower ends of the connecting pipe 6 are open, the fallen seeds will drop from the bottom of the connecting pipe 6, and the lower end of the connecting pipe 6 is connected to the upper end of the soil-breaking blades 17. There is still a certain distance between the bottom of the connecting pipe 6 and the ground, so that no soil adhesion problem will occur during the rotation of the connecting pipe 6, ensuring the smooth feeding of the seeds.

[0044] When the existing seeder feeds seeds, it can accurately control the number of seeds sown each time. However, for different seeds, the particle diameters of the seeds are different, generally ranging from 0.3 to 12 millimeters, with a large difference. In this way, when sowing seeds of different sizes, it is necessary to re-replace and assemble the feeding structure.

[0045] To this end, a first pipe 19 and a second pipe 20 are respectively fixed to opposite sides of two first support frames 21. A sliding rod assembly 23 capable of sliding inside the two pipes is arranged between the first pipe 19 and the second pipe 20. The sliding rod assembly 23 is connected by multiple rods with different diameters, and the diameters of the rods decrease from left to right. When seeds enter the seed feed bin 18 from the seed box, a second motor 29 drives the sliding rod assembly 23 to rotate. Since the diameter of the sliding rod assembly 23 is smaller than the diameters of the first pipe 19 and the second pipe 20, the seeds will fall on the upper surface of the sliding rod assembly 23. When the sliding rod assembly 23 rotates, the seeds can be smoothly transferred to the lower end. The number of seeds sown each time is within the moving range, thus realizing sowing smoothly. This structure is a common setting of a seed feeding box in the prior art. The improvement lies in that the second motor 29 adjusts its position through an electric telescopic rod 28 inside the second pipe 20, enabling the sliding rod assembly 23 to move between the first pipe 19 and the second pipe 20 while rotating. During the movement, rods with different diameter sizes on the sliding rod assembly 23 will move above the funnel 25. When the diameter of the rods on the sliding rod assembly 23 changes to adapt to the sowing of seeds of different sizes. For example, when the diameter of the rod increases, the pipe diameter difference between the rod and the first pipe 19 and the second pipe 20 becomes smaller, and the space for accommodating the passing seeds also becomes smaller, which is suitable for small-particle seeds. When the diameter of the rod decreases, the pipe diameter difference between the rod and the first pipe 19 and the second pipe 20 becomes larger, and the space for accommodating the passing seeds also becomes larger, which is suitable for large-particle seeds. Thus, according to the size of the diameter of the seeds to be sown, the electric telescopic rod 28 can be controlled to drive the sliding rod assembly 23 to adjust its position to solve the problem.

[0046] When the sandy soil leaks out from the through hole 15 and enters the soil with a higher clay content, it is necessary to accurately control the amount of sandy soil scattered, ensure that the scattered sandy soil in each area is more uniform, and at the same time avoid the problem of accumulation in the cylinder 4.

[0047] Therefore, a second transmission gear 9 is arranged on the connecting pipe 6. The first transmission gear 8 is installed at the end of the output shaft of the first motor 5. The first transmission gear 8 transmits kinetic energy to the second transmission gear 9 and the gear disk 10, driving the connecting pipe 6 to rotate. At the same time, a groove is presented on the upper part of the gear disk 10 for accommodating the second transmission gear 9 and the first transmission gear 8, and the cylinder body 4 is divided into two parts by the gear disk 10, ensuring that the material leakage hole 7 is located below the gear disk 10, so that the sandy soil will not contact the first transmission gear 8 and the second transmission gear 9. When the gear disk 10 rotates, the external cushion block 26 thereof will be slidably arranged in the annular track 27, playing a supporting effect on the gear disk 10. When the sandy soil particles leak out from the material leakage hole 7, since the gear disk 10 is always in the process of rotation, the baffle 11 connected to the lower end of the gear disk 10 will intermittently block the material leakage hole 7, so that the sandy soil particles falling in unit time are maintained within a stable range. A conical surface 16 is arranged at the central position of the bottom of the cylinder body 4, and the sandy soil will roll down from the conical surface 16 to the edge position of the cylinder body 4. At this time, a plurality of connecting rods 12 are installed outside the connecting pipe 6. The bottom of the connecting rod 12 is hinged with a straight plate 13. At the same time, a scraping tooth 14 is arranged at the bottom of the straight plate 13. During the rotation of the straight plate 13, the falling sandy soil can be pushed out from the through hole 15, ensuring that the sandy soil uniformly falls on the soil.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
