Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a rice rotary tillage, fertilization and seeding machine. Background Technology

[0002] Rice, as one of the world's most important food crops, is widely cultivated, and its yield is of great significance to ensuring global food security. Rotary tillage, fertilization, and sowing are key steps in rice cultivation, directly affecting the growth and final yield of rice. Traditional rice cultivation methods rely heavily on manual labor, which is not only labor-intensive and inefficient but also makes it difficult to ensure the uniformity and precision of sowing, thus affecting the yield and quality of rice. With the continuous development of agricultural mechanization technology, rice rotary tillage, fertilization, and sowing machines have emerged, bringing great convenience to rice cultivation. However, in practical applications, existing sowing machines still have many problems that urgently need to be solved.

[0003] During continuous sowing, many existing rice rotary tillage and fertilization planters struggle to control the rhythm and quantity of seed descent. Due to the lack of an effective intermittent sowing control mechanism, uneven seed distribution often occurs, resulting in excessively high sowing densities in some areas and excessively low sowing densities in others. Excessively high sowing densities restrict the growth space of rice plants, causing them to compete for nutrients, water, and light, making them more susceptible to pests and diseases and hindering normal growth and development. Conversely, excessively low sowing densities waste land resources, reduce yield per unit area, and fail to fully realize the land's productive potential. Utility Model Content

[0015] Preferably, the drive shaft passes through the discharge cylinder and extends therefrom, and the extended end of the drive shaft is rotatably mounted on the inside side of the discharge cylinder.

[0016] The beneficial effects of this utility model are:

[0017] 1. This rice rotary tillage and fertilization seeder, equipped with an opening and closing assembly, achieves intermittent movement of the driven mechanism through the cooperation of a half-gear, half-moon disc, driven shaft, driven gear, contact plate, connecting disc, first connecting shaft, and first connecting arm, all housed within the second housing. Furthermore, the sliding plate, sliding groove, and button within the mounting base are linked to a hydraulic cylinder on the support plate, causing the hydraulic cylinder to drive the linkage plate to slide reciprocally. This, in turn, drives the fourth connecting shaft and the second connecting arm to rotate periodically, causing the third connecting shaft to rotate periodically and drive multiple diverter plates installed at the discharge port to deflect intermittently. This achieves the periodic opening and closing of the discharge port, enabling intermittent seed sowing according to a set rhythm. This effectively avoids the problem of excessively high or low sowing density caused by uneven seeding during continuous sowing, improving the uniformity and accuracy of sowing. Simultaneously, the mechanical transmission structure achieves opening and closing control, preventing seed blockage, jamming, or waste, reducing reliance on the electrical control system, and ensuring stable operation of the equipment in complex field environments, thereby improving overall sowing efficiency and operational reliability.

[0018] 2. This rice rotary tillage and fertilization seeder is equipped with a seeding component. A feed hopper is connected to one side of the discharge cylinder on one side of the seeder body to receive seeds, and a discharge port is connected to the other side to discharge seeds. A scraper is fixedly mounted on the drive shaft inside the discharge cylinder. The drive shaft is driven by a power mechanism, and the scraper, rotating with the drive shaft, pushes the seeds falling from the feed hopper into the discharge cylinder towards the discharge port. A discharge plate is fixed outside the discharge port, with several drainage holes for even seed discharge. This structure achieves directional seed transport through the rotation of the scraper, ensuring the continuity and stability of seed transport and effectively preventing seed accumulation and blockage. Combined with subsequent opening and closing components, it enables precise, quantitative, and intermittent seeding, thereby improving seeding quality and operational efficiency.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] like Figures 1 to 5 As shown, the rice rotary tillage and fertilization seeder includes: a seeder body 1; a seeding component, which is installed on one side of the seeder body 1 and is used for sowing; and an opening and closing component, which is installed on one side of the seeder body 1 and is used to open and close the sowing outlet.

[0030] During operation, this rice rotary tillage and fertilization seeder uses the seeder body 1 as the structural support and power transmission base to drive the seeding component to complete the seeding operation. The seeding component is installed on one side of the seeder body 1 and connected to the storage bin, which is used to transport the seeds in the bin to the seeding outlet. The opening and closing component is installed at the seeding outlet to control the seed falling process. When the equipment moves to the working area, the seeding component starts to work, and the opening and closing component intermittently opens the seeding outlet according to the set rhythm, so that the seeds fall intermittently, thereby realizing intermittent seeding. This can prevent seed accumulation caused by continuous feeding and effectively control the seeding density. When the equipment is not in the seeding state, the opening and closing component remains closed to prevent seed leakage and waste. Through the cooperation of the seeding component and the opening and closing component, the automatic control of the seeding process and the improvement of the seeding accuracy are achieved.

[0031] like Figure 1 , Figure 2 As shown, the seeding assembly includes a discharge cylinder 3 installed on one side of the seeder body 1, a feed hopper 2 fixedly installed on one side of the discharge cylinder 3, and a discharge port 6 fixedly installed on the other side of the discharge cylinder 3. A second housing 12 is installed on one side of the seeder body 1, and a drive shaft 5 is rotatably installed inside the second housing 12. A scraper 4 is fixedly installed on the drive shaft 5 and rotatably installed inside the discharge cylinder 3. A discharge plate 10 is fixedly installed on one side of the discharge port 6, and a plurality of discharge outlets 11 are provided on the discharge plate 10.

[0032] During the sowing process, the seeding assembly uses the discharge cylinder 3, installed on one side of the seeder body 1, as the main channel for seed transfer. The feed hopper 2, also installed on one side of the discharge cylinder 3, receives seeds from the storage bin. Inside the discharge cylinder 3 is a rotatable scraper 4, fixedly mounted on the drive shaft 5. The drive shaft 5 is located within the second housing 12 on one side of the seeder body 1 and is driven to rotate by a power transmission device. When the drive shaft 5 rotates, the scraper 4 rotates accordingly within the discharge cylinder 3, causing seeds from the feed hopper 2 to fall into the discharge hopper. The seeds in the feed cylinder 3 are pushed to the other side of the discharge cylinder 3, that is, the direction of the discharge port 6. As the scraper 4 rotates, the seeds are continuously fed to the discharge port 6. The discharge port 6 is fixedly connected to the outside of the discharge plate 10. The discharge plate 10 has several discharge ports 11, which are used to orderly drop the seeds pushed here into the field from the discharge ports 11 according to the set path, so as to realize the continuous or intermittent delivery and sowing of seeds. The rotation of the scraper 4 realizes the pushing and directional delivery of seeds in the discharge cylinder 3, and then completes the sowing operation in conjunction with the opening and closing structure.

[0033] like Figure 3 , Figure 4 , Figure 5As shown, the opening and closing assembly includes a first housing 7 fixedly installed on one side of the discharge port 6. A mounting groove 25 is provided inside the discharge port 6, and several diverter plates 26 are rotatably installed within the mounting groove 25. A third connecting shaft 27 is fixedly installed on the diverter plate 26, and a second connecting arm 28 is fixedly installed on the third connecting shaft 27. A support plate 9 is fixedly installed on one side of the discharge port 6, and a hydraulic cylinder 8 is engaged with the support plate 9. A linkage plate 29 is installed at the output end of the hydraulic cylinder 8, and several fourth connecting shafts 30 are fixedly installed on the linkage plate 29. The other end of the fourth connecting shaft 30 is rotatably installed inside the first housing 7, and the second connecting arm 28 is rotatably connected to the fourth connecting shaft 30. The third connecting shaft 27 penetrates the first housing 7 and extends therethrough, with its extended end rotatably installed inside the first housing 7. The linkage plate 29 is slidably installed inside the first housing 7. A mounting base 22 is fixedly installed on the other side of the support plate 9, and a sliding arm 28 is slidably installed within the mounting base 22. A second connecting shaft 21 is fixedly installed on one side of the plate 31 and the slide plate 31. A connecting plate 18 is rotatably installed inside the second housing 12. A first connecting shaft 20 is fixedly installed on the connecting plate 18. A first connecting arm 19 is rotatably installed on the first connecting shaft 20. The first connecting arm 19 is rotatably installed with the second connecting shaft 21. A driven shaft 17 is fixedly installed on the connecting plate 18. A driven gear 16 is fixedly installed at one end of the driven shaft 17. A contact plate 15 is fixedly installed on one side of the driven gear 16. A half gear 14 is rotatably installed inside the second housing 12. A half-moon disc 13 is fixedly installed on one side of the half gear 14. One side of the contact plate 15 abuts against one side of the half-moon disc 13. A sliding groove 23 is provided on the mounting base 22. The slide plate 31 is slidably installed in the sliding groove 23. A button 24 is provided on one side of the inside of the sliding groove 23. One side of the slide plate 31 abuts against the button 24. The drive shaft 5 passes through the discharge cylinder 3 and extends outward. The extended end of the drive shaft 5 is rotatably installed on one side of the inside of the discharge cylinder 3.

[0034] The opening and closing assembly is used during the sowing operation to intermittently open and close the feed inlet 6, ensuring intermittent seed discharge. When the seeder enters the sowing area and begins operation, the power mechanism located in the second housing 12 drives the half gear 14 to rotate. A crescent disc 13 is fixedly connected to one side of the half gear 14. During rotation, the half gear 14 intermittently meshes with the driven gear 16, thereby providing intermittent rotational power to the driven gear 16. The driven shaft 17 is fixedly connected to the driven gear 16, so under the drive of the driven gear 16, the driven shaft 17 rotates synchronously and intermittently, driving the connecting disc 18, which is fixed coaxially with it, to rotate intermittently. Under the action of the intermittent rotation of the connecting disc 18 causing the first connecting arm 19 to swing periodically, the slide plate 31 reciprocates within the slide groove 23. One side of the slide plate 31 is connected to the button 24 located inside the slide groove 23. When the slide plate 31 slides into place, the button 24 is triggered. The button 24 controls the hydraulic cylinder 8 set on the support plate 9 to act. The output end of the hydraulic cylinder 8 is connected to the linkage plate 29. After the hydraulic cylinder 8 acts, it drives the linkage plate 29 to slide back and forth. Under the action of the linkage plate 29, the second connecting arm 28 deflects, thereby driving the third connecting shaft 27 fixedly connected to it to rotate synchronously. The third connecting shaft 27 passes through the first housing 7 and extends into the mounting groove 25. During its rotation, it drives several diversion plates 26 fixed on it to rotate. The diversion plates 26 deflect intermittently under the action of the third connecting shaft 27, so that the diversion plates 26 installed in the discharge port 6 open or close the discharge port 6 intermittently at a set rhythm, thereby realizing the intermittent discharge of seeds during the sowing process, thereby achieving the purpose of uniform sowing, avoiding blockage and saving seeds.
