[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0050] like Figures 1-3 As shown, this embodiment provides a seeder, including a frame 1, a rotary tillage mechanism 2, a furrowing and ridging mechanism 3, a sowing mechanism 4, and a ground wheel mechanism 5. The rotary tillage mechanism 2 is installed in front of the frame 1 and is used to rotary tillage and break up the soil, and gather the broken soil to the center of the ridge. The furrowing and ridging mechanism 3 is installed on the frame 1 and located behind the rotary tillage mechanism 2. The furrowing and ridging mechanism 3 is used to rid and furrow the soil broken up by the rotary tillage mechanism 2. The sowing mechanism 4 is installed on the frame 1 and located behind the furrowing and ridging mechanism 3. The sowing mechanism 4 is used to sow seeds and / or fertilizer into the furrows opened by the furrowing and ridging mechanism 3, and to cover and compact the soil. The ground wheel mechanism 5 is connected to the sowing mechanism 4 and is used for the operation of the sowing mechanism 4.

[0051] In this embodiment, the seeder 42 includes a frame 1 and a rotary tillage mechanism 2, a furrowing and ridging mechanism 3, a sowing mechanism 4, and a ground wheel mechanism 5 mounted on the frame 1. When the seeder is working, the rotary tillage mechanism 2 is driven to rotate by an external power source. The rotary tillage mechanism 2 tillages and breaks up the soil. The furrowing and ridging mechanism 3 furrows and rids the soil broken up by the rotary tillage mechanism 2. The furrows opened by the furrowing and ridging mechanism 3 can be used for sowing or fertilizing. At this time, the seeds or waste are sown into the furrows opened by the furrowing and ridging mechanism 3 through the sowing mechanism 4. The sowing mechanism 4 then covers the sown seeds or fertilizer with soil and compacts it to prevent rainwater from washing away the soil. The ground wheel mechanism 5 can provide support and movement for the seeder. In this embodiment, the seeder uses a rotary tillage mechanism 2 to gather the broken soil towards the center of the ridge, facilitating subsequent furrowing and ridging. The gathered ridges ensure the furrowing depth of the furrowing and ridging mechanism 3. The sowing mechanism 4 then covers and compacts the soil after planting in the furrows, effectively preventing rainwater erosion and ensuring the quality of peanut planting. Furthermore, the ground wheel mechanism 5 and the sowing mechanism 4 are connected by a drive system. The ground wheel mechanism 5 transmits power to the sowing mechanism 4 during movement to control the seed distribution process, facilitating the sowing process.

[0052] like Figure 1 As shown in the figure, in one embodiment, a soil-entry plow 11 is provided at the front of the frame 1. The soil-entry plow 11 is located on both sides of the front of the frame. By providing the soil-entry plow 11, it is convenient for the seeder to enter the soil when it is working, thereby facilitating the rotary tillage and breaking up of the soil. A support block 12 is provided at the rear of the frame 1. The support block 12 is used to support the seeder when it is not working.

[0053] like Figure 2 , 6 As shown in Figure 7, the rotary tillage mechanism 2 includes a rotary tillage shaft 21 and two sets of rotary tillage blades. The plane located at the center of the rotary tillage shaft 21 and perpendicular to the axis of the rotary tillage shaft 21 is the first plane 22. Both sets of rotary tillage blades are mounted on the rotary tillage shaft 21, and the two sets of rotary tillage blades are located on both sides of the first plane 22. Each set of rotary tillage blades includes several rotary tillage blades 23, and the tips 232 of the rotary tillage blades 23 face the first plane 22. In each set of rotary tillage blades, several rotary tillage blades 23 are staggered along the length direction of the axis of the rotary tillage shaft 21.

[0054] It should be noted that the rotary tillage mechanism 2 may include multiple rotary tillage shafts 21, which can rotate synchronously. Each rotary tillage shaft 21 is equipped with two sets of rotary tillage blades. An external power source drives a gearbox 25, which in turn drives the multiple rotary tillage shafts 21 to rotate, thereby causing the sets of rotary tillage blades 23 on the rotary tillage shafts 21 to rotate and break up the soil. Figure 3 and 6As shown, the rotary tillage mechanism 2 includes two rotary tillage shafts 21, each with two sets of rotary tillage blades mounted on it. These blades are connected to the two rotary tillage shafts 21 via a gearbox 25. This embodiment uses... Figure 1 The two rotary tillage shafts 21 are illustrated by way of example.

[0055] In this embodiment, the plane located at the center of the rotary tiller 21 and perpendicular to the axis of the rotary tiller 21 is the first plane 22. It can be understood that, as... Figure 2 As shown, the first plane 22 is the center plane of the ridge, meaning that the center of the rotary tillage shaft 21 is located on the center plane of the ridge. The two sets of rotary tillage blades are located on both sides of the first plane 22, that is, the two sets of rotary tillage blades 23 are located on both sides of the center plane of the ridge. Since each set of rotary tillage blades includes several rotary tillage blades 23, the tips 232 of the rotary tillage blades 23 face the first plane 22. When the rotary tillage mechanism 2 of this embodiment is used to rotary tillage and break up the soil, the tips of the rotary tillage blades 23 facing the center plane of the ridge will gather the broken soil towards the center plane of the ridge, so that the broken soil is gathered together, which facilitates the subsequent furrowing and ridging of the soil, and ensures that the furrows dug by the furrowing and ridging mechanism 3 on the gathered soil have sufficient depth, thus ensuring the planting quality of peanuts.

[0056] like Figure 6 and 7 As shown, in one embodiment, in each group of rotary tillers 23, several rotary tillers 23 are staggered along the length of the axis of the rotary tiller shaft 21. By staggering the several rotary tillers 23 along the length of the axis of the rotary tiller shaft 21, adjacent rotary tillers 23 have an included angle, and when rotary tilling the soil, the staggered rotary tillers 23 can fully break up the soil.

[0057] like Figure 6 , 7 As shown in Figure 8, the rotary tiller 23 includes two rotary tiller blades, each blade comprising a rotary tiller body 231 and a rotary tiller tip 232 connected to each other; of the two rotary tiller blades of the rotary tiller 23, the two rotary tiller body parts 231 are located on the same vertical plane, and the rotary tiller tip 232 faces the direction of the first plane 22.

[0058] In this embodiment, the rotary tiller 23 includes two rotary tiller blades. The two rotary tiller blades 231 of the same rotary tiller 23 are located on the same vertical plane, and the rotary tiller blade tip 232 faces the direction of the first plane 22. That is, by bending the rotary tiller blade tip 232, the rotary tiller blade tip 232 is made to face the center of the ridge. When rotary tilling the soil, the bent rotary tiller blade tip 232 pushes the broken soil towards the center of the ridge, thereby gathering the broken soil towards the center of the ridge, which facilitates subsequent furrowing and ridging.

[0059] like Figure 8As shown in one embodiment, the rotary tiller blade also includes a rotary tiller holder, which is fixedly connected to the rotary tiller shaft 21. The end of the rotary tiller blade body 231 away from the rotary tiller tip 232 is inserted into the rotary tiller holder. By fixing the rotary tiller holder to the rotary tiller shaft 21 and inserting the end of the rotary tiller blade body 231 away from the rotary tiller tip 232 into the rotary tiller holder, it is convenient to replace the rotary tiller blade body 231 or the rotary tiller tip 232 when it is damaged.

[0060] like Figure 6 , 7 As shown in Figure 9, the rotary tillage mechanism 2 further includes a central blade 24, which is installed at the center of the rotary tillage shaft 21. The central blade 24 includes two central blades, each comprising a central blade body portion 241 and a central blade tip portion 242 connected to each other. The central blade body portions 241 of the two central blades are located on the first plane 22, and the two central blade tips 242 are bent in a direction away from the first plane 22, with the two central blade tips 242 facing in opposite directions.

[0061] In this embodiment, by installing the central blade 24 at the center of the rotary tillage shaft 21, the soil at the center can be broken up to ensure the quality of soil breaking up, thereby ensuring the quality of peanut sowing; the tips of the two central blades 242 face away from the first plane 22, that is, the tips of the central blades 242 and the tips of the rotary tillage blades 23 on both sides are opposite to each other. When rotary tilling the soil, on the one hand, the soil at the center of the ridge can be broken up, and on the other hand, the tips of the rotary tillage blades 232 on both sides can be used to gather the broken soil towards the center of the ridge.

[0062] like Figure 9 As shown in one embodiment, the central blade also includes a central blade holder 243, which is fixedly connected to the rotary tillage shaft 21. One end of the central blade body 241, away from the central blade tip 242, is inserted into the central blade holder 243. The central blade holder 243 is fixedly connected to the rotary tillage shaft 21, and the end of the central blade body 241, away from the central blade tip 242, is inserted into the central blade holder, facilitating replacement when the central blade body 241 or the central blade tip 242 is damaged.

[0063] like Figure 6 and 7 As shown, the rotary tillage mechanism 2 also includes a gearbox 25 and a ditching blade 26. The output end of the gearbox 25 is connected to the rotary tillage shaft 21 for transmission. The ditching blade 26 is mounted on the gearbox 25.

[0064] In this embodiment, the output end of the gearbox 25 is connected to the rotary tiller 21 for transmission. The gearbox 25 controls the rotational speed of the rotary tiller 21 and can control the forward or reverse rotation of the rotary tiller 21 to fully break up the soil. Then, the furrowing blade 26 installed on the gearbox 25 can make furrows between two adjacent ridges to facilitate subsequent peanut planting.

[0065] like Figure 3 , 4 As shown in Figure 10, the ditching and ridging mechanism 3 includes a ridging roller 31, a retaining plate 32, several sets of ditching components, and several sets of ridging components; the ridging roller 31 is rotatably connected to the frame 1, and the ridging roller 31 and the rotary tillage shaft 21 are connected in a driving connection; the ditching component includes a ditch opener 33 and two ditching discs 34, the retaining plate 32 is installed on the frame 1, the ditch opener 33 is installed on the retaining plate 32, and the two ditching discs 34 are spaced apart on the ridging roller 31, with the gap between the two ditching discs 34 corresponding to the ditch opener 33; the ridging component includes a soil divider 35 and two ridging discs 36, the soil divider 35 is installed on the frame 1, and the two ridging discs 36 are spaced apart on the rotary tillage shaft 21, with the gap between the two ridging discs 36 corresponding to the soil divider 35.

[0066] In this embodiment, the ridging roller 31 is rotatably connected to the frame 1, and the ridging roller 31 and the rotary tiller 21 are drive-connected. Specifically, the rotary tiller 21 and the ridging roller 31 are connected by a chain drive. When the rotary tiller 21 rotates, it drives the ridging roller 31 to rotate. The furrowing assembly includes a furrow opener 33 and two furrowing discs 34. The soil retaining plate 32 is installed on the frame 1, the furrow opener 33 is installed on the soil retaining plate 32, and the two furrowing discs 34 are spaced apart on the ridging roller 31. The gap between the two furrowing discs 34 corresponds to the furrow opener 33. When the seeder needs to furrow, the two furrow openers... The two furrowing discs 34 are inserted into the soil broken up by the rotary tillage mechanism 2. The furrow opener 33 presses down the soil in the two furrowing discs 34 to form planting furrows for sowing or fertilization. The ridging assembly includes a soil divider 35 and two ridging discs 36. The soil divider 35 is installed on the frame 1, and the two ridging discs 36 are spaced apart on the rotary tillage shaft 21. The gap between the two ridging discs 36 corresponds to the soil divider 35. When ridging is required, the two ridging discs 36 are inserted into the broken soil, and the soil divider 35 pushes and compacts the soil to form a furrow. Two ridges are formed on both sides of the furrow. As one embodiment, the ridging roller 31 is equipped with four furrowing components. Of course, the number of furrowing components and ridging components can be set according to the actual situation, and is not limited here.

[0067] like Figure 4As shown, the trencher 33 includes a connecting part 331 and a trenching cutter part 332. One end of the connecting part 331 is fixedly connected to the retaining plate 32, and the other end of the connecting part 331 is fixedly connected to the trenching cutter part 332. The trenching cutter part 332 is bent. The soil divider 35 includes two soil dividing plates 351 arranged opposite to each other and a baffle 352 arranged between the two soil dividing plates 351. The two soil dividing plates 351 and the baffle 352 enclose each other to form a ridge trench.

[0068] In this embodiment, one end of the connecting part 331 is fixedly connected to the retaining plate 32, and the other end of the connecting part 331 is fixedly connected to the ditching blade part 332. The ditching blade part 332 is bent. When ditching, the bent ditching blade part 332 compacts the soil between the two ditching discs 34 to form a planting ditch. The soil divider 35 includes two soil dividing plates 351 arranged opposite to each other and a baffle 352 arranged between the two soil dividing plates 351. The two soil dividing plates 351 and the baffle 352 enclose each other to form a ridge-building groove. When building ridges, the two soil dividing plates 351 and the baffle 352 push and compact the soil to form a ridge, so that ridges are formed on both sides of the ridge.

[0069] like Figure 10 As shown in the figure, in one embodiment, the ditching and ridging mechanism 3 further includes a scraper 37, which is disposed on the retaining plate 32. The scraper 37 is used to remove soil from the ridging roller 31 to prevent soil from sticking to the ridging roller 31, hindering the rotation of the ridging roller 31, and thus affecting the ditching and ridging of the soil. Preferably, the scraper 37 is a rubber plate.

[0070] like Figure 11 and 12 As shown, the sowing mechanism 4 includes a sowing frame 41, a seeder 42, and a seed metering guide 43; the sowing frame 41 is installed on the frame 1, and the seeder 42 is installed on the frame 1; a feeding space is formed between the furrow opener 33 and the furrow opener 34 of the furrow opening assembly, and the seed metering guide 43 is installed at the bottom of the seeder 42 and is located within the feeding space.

[0071] In this embodiment, the seeding frame 41 is installed on the frame 1, located behind the rotary tillage mechanism 2. The seeder is installed on the seeding frame 41 and has a hopper for storing seeds or fertilizer. The hopper is connected to the seed discharge guide 43, and the seeds or fertilizer in the hopper can enter the planting furrow through the seed discharge guide 43. A discharge space is formed between the furrow opener 33 and the furrow opener plate 34 of the furrow opening component. The seed discharge guide 43 is installed at the bottom of the seeder 42 and is located in the discharge space. When the furrow opening component opens the planting furrow, the seed discharge guide 43 located in the discharge space will drop the seeds or fertilizer into the planting furrow, ensuring the sowing quality.

[0072] like Figure 11 and 12 As shown, the sowing mechanism 4 also includes a soil covering device 44 and a pressing wheel 45; the soil covering device 44 is adjustablely installed on the sowing frame 41 and is located behind the seed discharge guide tube 43; the pressing wheel 45 is installed on the sowing frame 41 and is located behind the soil covering device 44.

[0073] In this embodiment, the soil covering device 44 is adjustablely mounted on the seeding frame 41. Specifically, the soil covering device 44 is a block-shaped plate with multiple fixing holes on its top. It can be fixed to one of the fixing holes by fixing bolts to achieve height adjustment of the soil covering device 44 on the seeding frame 41. The soil covering device 44 is located behind the seed discharge guide 43. After the seeder drops the seeds or fertilizer into the planting furrow through the seed discharge guide 43, the quick-release plate soil covering device 44 pushes the soil on both sides of the planting furrow into the planting furrow, thereby covering the seeds or fertilizer with soil. The compaction wheel 45 is mounted on the seeding frame 41 and is located behind the soil covering device 44. After the soil covering device 44 covers the seeds or fertilizer with soil, the compaction wheel 45 compacts the soil after covering, effectively preventing rainwater erosion, effectively reducing the risk of ridge collapse, and ensuring planting quality.

[0075] In this embodiment, the ground wheel 52 is rotatably connected to the movable support 51, the connecting support 53 is drivenly connected to the movable support 51, and the connecting support 53 and the movable support 51 can be drivenly connected by a chain box. The gearbox 54 is also drivenly connected to the connecting support 53 by a chain box. The seed metering shaft 55 is drivenly connected to the gearbox 54 and rotatably connected to the seeder 42. When the seeder is working, the ground wheel 52 moves on the ground, thereby transmitting the power chain box to the gearbox 54. The gearbox 54 drives the seed metering shaft 55 to rotate. The seed metering shaft 55 can control the speed at which the seeder 42 delivers seeds or fertilizer to the seed metering guide tube 43, driving the seeder 42 to work, ensuring uniform sowing or fertilization, and ensuring sowing quality.

[0076] like Figure 13As shown in the figure, in one embodiment, the ground wheel mechanism further includes a tensioning component 56, which is mounted on the movable frame 51. The tensioning component 56 is used to tension the ground wheel 52 to adjust the tightness of the ground wheel 52 and facilitate the operation of the seeder.

[0077] like Figure 3 As shown in the figure, as an example, the ridge parameters are: ridge spacing 90cm, ridge width 50cm, ridge depth 20-25cm, ridge furrow bottom width 14cm, and planting furrow depth 5cm.

[0078] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
