Description

Technical Field

[0001] This invention relates to the field of agricultural seeding machinery, specifically a rotary tillage wheat seed and fertilizer layered wide-width uniform sowing and furrowing component. Background Technology

[0002] The quality of wheat sowing directly affects seed germination, seedling uniformity, population structure, root development, and later yield formation. In wheat sowing operations, reasonable sowing depth, uniform lateral seed distribution, stable seed-fertilizer spacing, and good seedbed conditions are important factors to ensure uniform, healthy, and robust seedlings. With the development of mechanized wheat sowing technology, the traditional narrow-row sowing method is gradually developing towards wide-row sowing, strip sowing, and layered application of seeds and fertilizers.

[0003] Existing wheat planters typically break up the soil and form furrows using rotary tillers or furrow openers, and then use fertilizer and seed delivery tubes to deliver fertilizer and seeds respectively. In actual operation, the lateral soil disturbance range formed by the unidirectional curved rotary tillers is limited. When the rotary tillers are not arranged properly, it is easy to cause uneven soil distribution on both sides of the furrow, which will cause changes in the subsequent fertilizer application position, sowing depth and soil covering thickness, affecting the stability of the seed and fertilizer landing point.

[0004] Existing seed guiding structures mostly use vertical or near-vertical seed guiding tubes. Seeds fall directly into the sowing furrow from the outlet of the seed guiding tube, which tends to concentrate directly below the seed guiding tube, resulting in a dense seed distribution in the middle of the sowing strip and a sparse seed distribution on both sides. Although some devices are equipped with seed dispersing plates, reflective plates, or seed distribution boxes, the vibration generated when the seeder is working and the changes in the seed falling speed may still cause problems such as unstable seed rebound direction, local accumulation, and uneven lateral distribution, making it difficult to form a sowing strip with a stable width and uniform distribution. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a rotary tillage wheat seed and fertilizer layered wide-width uniform sowing furrowing component to solve the technical problems of unstable seed output direction, local accumulation and uneven lateral distribution in existing wheat seeders.

The inner wall of the clamping rod near the fixed column is slidably connected to a sliding plate, and each sliding plate is hinged to an expansion rod. The other end of the expansion rod connected to each set of clamping rods is rotatably connected to the push plate inside the temporary storage cavity.

[0011] The present invention is further configured such that the scraping mechanism includes a reciprocating rotating column, a scraping plate and a brush. The reciprocating rotating column is laterally rotatably connected in the middle of the inside of the seed storage chamber, and multiple sets of opposing scraping plates are connected to both sides of the lower end of the reciprocating rotating column. Each set of scraping plates consists of a scraper and a guide plate.

[0031] The embodiments of the present invention will now be described.

[0032] A rotary tillage wheat seed and fertilizer layered wide-width uniform sowing and furrowing component, such as Figure 1-8As shown, the system includes a fertilizer tube 1, a seed tube 2, and a furrowing blade 10. The furrowing blade 10, fertilizer tube 1, and seed tube 2 are connected to a rotary tillage seeder in that order. The furrowing blade 10 has a greater spacing between its farthest ends than the seed tube 2. The furrowing blade 10 first creates furrows in the tilled land. Then, the fertilizer tube 1 spreads fertilizer into the furrows. Covering plates 4 are placed on both sides of the bottom of the fertilizer tube 1, with the furthest spacing between the covering plates 4 greater than the width of the seed tube 2. The covering plates 4 then scrape the inner wall of the furrows for initial soil covering. Finally, the seed tube 2 spreads seeds into the furrows to complete the sowing process. The middle section of the seed tube 2 is designated as a seed storage chamber 5. The bottom end of the sub-tube 2 is configured as a seed equalization chamber 6 connected to the seed storage chamber 5. The top end of the seed equalization chamber 6 is connected to the seed storage chamber 5. The bottom end of the seed equalization chamber 6 is an opening. A fixed column 901 is horizontally fixedly connected in the middle of the inside of the seed equalization chamber 6. A rotating cylinder 902 is rotatably connected inside the seed equalization chamber 6. Multiple rows of temporary storage chambers 904 are evenly opened on the outer surface of the rotating cylinder 902. A reciprocating rotating column 801 is horizontally rotatably connected in the middle of the inside of the seed storage chamber 5. Multiple sets of opposing scraping plates are connected to both sides of the lower end of the reciprocating rotating column 801. Each set of scraping plates consists of a scraper 802 and a guide plate 803 inclined towards the scraper 802.

[0033] During the reciprocating rotation of the reciprocating column 801, the scraper 802 scrapes the wheat seeds into the temporary storage chamber 904. At the same time, the inclined guide plate 803 continuously pushes the wheat seeds below the scraper. Both sides of the inside of the seed tube 2, located between the seed storage chamber 5 and the seed equalization chamber 6, are equipped with leather brushes 804 that cooperate with the surface of the rotating cylinder 902. When the rotating cylinder 902 rotates, the temporary storage chamber 904 containing wheat seeds passes through the leather brushes 804. The leather brushes 804 can sweep away the wheat seeds that exceed the surface of the rotating cylinder 902, preventing the wheat seeds from exceeding the inner wall of the seed equalization chamber 6 and getting stuck.

[0034] The included angle between any two opposing guide plates 803 is greater than the included angle between any two scrapers 802, so that the wheat seeds can flow more easily between the guide plates 803 and the scrapers 802, preventing material jamming.

[0035] Furthermore, each temporary storage cavity 904 has several clamping rods 911 rotatably connected to its inner wall, and a push rod 905 slidably connected to the bottom surface of each temporary storage cavity 904. Each group of push rods 905 arranged laterally is connected to a plate 906. One end of each push rod inside the temporary storage cavity 904 is connected to a push plate 908. The outer wall of the fixing post 901 is connected to multiple sets of guide rings 903, and each set of guide rings 903 engages with both ends of each set of annularly arranged plates 906. The guide rings 903 are in a [missing information - likely a specific orientation or shape]. The ring is annular, and the bottom end of the guide ring 903 is open. The opening of the guide ring 903 faces the bottom surface of the uniform cavity 6. The thickness of the guide ring 903 gradually decreases from one end to the other end. The thinning process of the guide ring 903 is divided into three sections. Each clamping rod 911 has a sliding plate 910 slidably connected to the inner wall of one end near the fixed column 901. Each sliding plate 910 is hinged to an expansion rod 909. The other end of the expansion rod 909 connected to each set of clamping rods 911 is rotatably connected to the push plate 908 inside the temporary storage cavity 904.

[0036] like Figure 4 and Figure 9 As shown, during sowing, the belt plate 906 is located at the opening of the guide ring 903. At this time, the belt plate 906 is disengaged from the guide ring 903, and the reset spring 907 is in a fully contracted state. Due to the limitation of the cavity wall of the temporary storage cavity 904, the clamping rod 911 is in a vertical state, and its opening is in the maximum state, and it can no longer expand outward. The reset spring 907 pulls the belt plate 906 to push the push rod 21 and the push plate 908 to drive the slide plate 910 and the expansion rod 909 to be fully pushed out, pushing the seeds onto the soil. At this time, the slide plate 910 is located at the head end of the groove of the clamping rod 911. When the rotating drum 902 rotates, it drives the temporary storage cavity 904, which has completed sowing, to pass through three gradually thickening sections from the thin end of the guide ring 903.

[0037] When the belt plate 906 enters the first section of the guide ring 903, the thinnest part of the guide ring 903 is lower than the bottom surface of the belt plate 906 in its fully contracted state. When the belt plate 906 moves, the guide ring 903 squeezes the belt plate 906 to gradually approach the fixed post 901, thereby stretching the reset spring 907. At the same time, it drives the push rod 905, push plate 908, expansion rod 909 and slide plate 910 to slide. The expansion rod 909 drives the slide plate 910 to move from the head end to the tail end of the slide groove, while the angle of the clamping rod 911 remains unchanged.

[0038] like Figure 4 and Figure 10As shown, when the belt plate 906 moves to the second section of the guide ring 903, the slide plate 910 is located at the tail end of the groove of the clamping rod 911, and the clamping rod 911 is in a vertical state. At this time, the space formed inside the clamping rod 911 is at its maximum, and the temporary storage cavity 904 in this state faces the seed storage cavity 5. The thickness of the second section of the guide ring 903 remains unchanged so that the opening of the clamping rod 911 remains at its maximum when the temporary storage cavity 904 is rotated from one side of the leveling mechanism to the other side. The wheat seeds are scraped into the temporary storage cavity 904 by the leveling mechanism 8.

[0039] like Figure 4 , Figure 7 and Figure 11 As shown, the rotating drum 902 continues to rotate, driving the belt plate 906 into the third section. The third section of the guide ring 903 is divided into a gradually thickening pressure section and a holding section with a constant thickness. The holding section is the thickest section of the guide ring 903. The pressure section of the guide ring 903 first further squeezes the belt plate 906 closer to the fixed post 901. Since the slide plate 910 is already at the end of the slide groove, it cannot continue to slide. As the push plate 908 continues to move, the expansion rod 909 can only rotate, pushing the tail end of the clamping rod 911 to expand outward and its head end to contract inward, clamping the wheat grains to prevent them from falling out before the temporary storage cavity 904 is completely separated from the inner wall of the uniform seeding cavity 6. Then it enters the holding section to keep the clamping rod 911 in a tightened state.

[0040] Finally, the belt plate 906 disengages from the guide ring 903 at the notch, the reset spring 907 contracts, and pulls the belt plate 906 to push the push rod 21 and the push plate 908 outward. The push plate 908, through the slide plate 910 and the expansion rod 909, first pulls the clamping rod 911 to rotate to a vertical state. Then, the push plate 908, through the expansion rod 909, pulls the slide plate 910 outward, so that the push plate 908 is fully pushed out, pushing the seed onto the soil, completing the cycle.

[0041] Each clamping rod 911 is fitted with a rubber elastic ring at its tail end, so that the clamping rod 911 can be tightened and kept in a vertical state when no other external force is applied.

[0042] Furthermore, to prevent wheat grains from falling into the gap between the clamping rod 911 and the expansion rod 909 and getting stuck in the mechanism, a covering film 912 is applied to the outer surface of the rotating drum 902, the clamping rod 911, and the push plate 908. When the device is working, the wheat grains are inside the covering film 912 in the temporary storage chamber 904. The covering film 912 is made of elastic rubber to accommodate the movement of the internal structure of the sorting mechanism 9. A linear bearing is provided on the inner wall of the rotating drum 902 to wrap the push rod 905 and prevent the push rod 905 from getting stuck when it is pushed out.

[0043] In order for the strip plate 906 to adapt to the gradual thickness of the guide ring 903, the push rod 905 and the strip plate 906 are hinged, and the rotation angle between the strip plate 906 and the push rod 905 is 10 degrees. Rollers that cooperate with the guide ring 903 are rotatably connected at both ends of the strip plate 906 to reduce the wear of the strip plate 906 and the guide ring 903.

[0044] like Figure 2 , Figure 3 and Figure 6 As shown, a drive device 7 that provides power to the seeding mechanism 9 and the leveling mechanism 8 is installed on the outer wall of the seeding chamber 6. A motor 701 is installed on the outer wall of the seeding chamber 6, and the output end of the motor 701 is connected to a drive gear 702 that meshes with the outer wall of the rotating drum 902. An eccentric wheel 704 is rotatably connected to one end of the seeding chamber 6, and a transmission chain 705 is sleeved on the output end of the motor 701 and the eccentric wheel 704. The eccentric wheel 704 is rotatably connected to a connecting rod 703 that is rotatably connected to the reciprocating rotating column 801. When the motor 701 is working, it can directly drive the rotating drum 902 to rotate through the drive gear, and drive the eccentric wheel 704 to rotate through the transmission chain 705, and then drive the reciprocating rotating column 801 to rotate reciprocally through the connecting rod 703.

[0045] Bearings are embedded at both ends of the rotating drum 902. The outer wall of the bearing contacts the inner wall of the uniform cavity 6, which facilitates the rotation of the rotating drum 902.

[0046] Both fertilizer tube 1 and seed tube 2 are equipped with connecting plates 3 on their adjacent sides, and both connecting plates 3 are provided with corresponding waist holes to adjust the installation height of fertilizer tube 1 and seed tube 2 to adapt to different fertilization depth and sowing depth requirements.

[0047] In use, the trenching blade 10 first breaks up the soil and pushes it to both sides to create trenches, forming troughs. Fertilizer falls into the troughs through the fertilizer pipe 1. Then, the covering plate 4 scrapes the side walls of the troughs, causing some soil to collapse onto the fertilizer surface. Seeds fall into the seed storage chamber 5 through the seed pipe 2. Then, the reciprocating rotating column 801 drives the scraper 802 to scrape the seeds into the corresponding temporary storage chamber 904. The rotating cylinder 902 rotates, causing the temporary storage chamber 904 filled with seeds to move away from the seed storage chamber 5. At this time, the next row of empty temporary storage chambers... The cavity 904 moves to the bottom of the seed storage cavity 5. The guide ring 903 of the third section further squeezes the belt plate 906, causing the head end of the clamping rod 911 to tighten and clamp the wheat seeds. This prevents the wheat seeds from rubbing against the inner wall of the seed distribution cavity 6 during rotation and damaging the seeds. The rotating drum 902 then rotates until the belt plate 906 disengages from the guide ring 903. The reset spring 907 resets and pushes the push rod 905 to extend. At the same time, the expansion rod 909 and the sliding plate 910 drive the clamping rod 911 to expand, popping the seeds out and evenly dropping them onto the soil surface.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
