Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a wheat no-till planter suitable for conservation tillage. Background Technology

[0002] Traditional wheat cultivation relies on multiple land preparation operations, which directly damage the original soil structure, resulting in loose soil aggregates, reduced erosion resistance, and serious soil erosion problems. This not only reduces soil fertility but also has a negative impact on the agricultural ecological environment, making it difficult to meet the needs of modern sustainable agricultural development.

[0003] While no-till technology, as an alternative, can effectively reduce soil disturbance and protect soil structure, it has many shortcomings in practical applications. Among them, clogging is particularly prominent. Residual stubble from the previous crop and straw covering the ground are very likely to entangle and clog the furrow openers during sowing, leading to frequent interruptions in sowing operations, seriously affecting the continuity and efficiency of sowing, and increasing planting costs.

[0004] Meanwhile, no-till technology also presents challenges in seed-fertilizer mixing and sowing depth control. Improperly setting the spacing between seeds and fertilizer in the same furrow can easily lead to excessively high local fertilizer concentrations, causing seedling burn and significantly reducing seed germination rates. On uncultivated, hard, and undulating land, the furrow opener struggles to maintain a stable depth, resulting in inconsistent seed sowing depth and uneven germination. Furthermore, full-width soil breaking up generates significant disturbance, accelerating soil moisture evaporation and reducing moisture retention, which is detrimental to seed germination and seedling growth. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a no-till wheat seeder suitable for conservation tillage, solving the problems of previous crop stubble and surface straw easily tangling and clogging the furrow opener, affecting the continuity of sowing. Improper spacing of seeds and fertilizer in the same furrow or at the same location can easily cause seedling burn, affecting germination rate. On uncultivated, hard, undulating ground, the furrow opener has difficulty maintaining a stable depth, leading to uneven germination. Extensive soil disturbance from full-width soil breaking leads to rapid soil moisture evaporation, which is detrimental to seed germination.

The first lower connecting rod 705 is used to support the grass cutting disc 706, keeping the grass cutting disc 706 stable. The grass cutting disc 706 is used to cut the stubble and straw in the soil, preventing the stubble and straw from clogging the guide pipe 810. The grass cutting disc connecting plate 708 is used in conjunction with the side connecting rod 707, so that the grass cutting disc 706 moves in a specified direction and remains stable.

[0024] The stabilizing assembly includes two mounting brackets 712, which are mounted on the outside of the lower crossbeam 702 via quick-release components.

[0027] The hydraulic valve body 13 is connected to the hydraulic oil pipe, hydraulic tie rod 6, adjusting cylinder 704, hydraulic cylinder 713 and hydraulic cylinder 902 respectively. The hydraulic valve body 13 controls the operation of each hydraulic device, thereby realizing overall folding, reducing volume and facilitating storage and transportation.

[0028] A seed-fertilizer integrated box 2 is installed between the tops of multiple front connecting rods 4 of the contour frame. Multiple seed metering devices 3 are installed at the bottom of the seed-fertilizer integrated box 2. Two ground wheels 5 are installed at the bottom of the contour frame 1. The seed-fertilizer integrated box 2 is used to store seeds and fertilizers, thus facilitating sowing. The seed metering devices 3 are used to discharge the seeds and fertilizers inside the seed-fertilizer integrated box 2 and transport them into the seed-fertilizer conduit sleeve 808. Since the weight of the seeds, fertilizers and hopper is suspended by the tractor, it will not exert changing pressure on the furrowing seed-fertilizer dispensing mechanism 8, thus avoiding the impact on the sowing depth. The ground wheels 5 are used to support the entire device, enabling the device to move in the field and remain stable.

[0029] One end of the elastic support plate 803 is installed inside the single fixed bracket 801, and the other end of the elastic support plate 803 is adjustablely installed inside the guide groove plate 804 by bolts, so that the elastic support plate 803 remains stable and its toughness can be adjusted.

[0032] The quick-release assembly includes two fixed plate connecting plates 10 and four wedge blocks 12. The fixed plate connecting plates 10 and the wedge blocks 12 abut against the frame crossbeam 102 and crossbeam 702, respectively. The two wedge blocks 12 on the same side are fastened together by bolts. The fixed plate connecting plates 10 are used to increase the contact area with the frame crossbeam 102 or crossbeam 702, thereby increasing the friction and fastening. The fixed plate connecting plates 10 fit with the corresponding parts through the grooves at the four corners. The wedge blocks 12 are used to cooperate with the inclined surfaces on the inner side of the corresponding parts. By tightening the bolts, the two wedge blocks 12 are brought closer to each other, so that the wedge blocks 12 can squeeze the frame crossbeam 102 or crossbeam 702, thereby fixing the corresponding parts in the appropriate position. The modular design facilitates disassembly, maintenance or replacement.

[0033] Working Principle: When using this equipment for sowing, seeds and fertilizer are placed into the seed-fertilizer integrated box 2. The hydraulic valve body 13 then controls the operation of various hydraulic systems, unfolding the device from its folded state. The folded state makes the device easier to transport, reduces its size, and facilitates storage. Once unfolded, sowing can begin. The equipment is moved by a tractor, with the grass-cutting mechanism 7 at the front. The hydraulic valve body 13 controls the extension and retraction of the adjusting cylinder 704, causing the first lower connecting rod 705 to move the grass-cutting disc 706 up and down, adjusting the depth of the grass-cutting disc 706 into the soil. Cutting off residual roots and straw in the soil prevents blockage of the furrowing, seeding, and fertilizer dispensing mechanism 8, thus affecting sowing efficiency. While the equipment moves, the front vertical shovel 806 vertically breaks the soil to form a planting furrow. Then, the cutting wing shovel 812 horizontally peels the soil, and fertilizer is transported into the seed-fertilizer conduit sleeve 808. It is then guided by the partition plate 809 to a deeper soil layer below the center of the planting furrow. The seed flow is precisely blown into the guide tube 810 by the seed metering device 3 and discharged into the shallower positions on both sides of the planting furrow. Since the tractor bears the weight of the equipment, it does not exert any pressure on the furrowing, seeding, and fertilizer dispensing mechanism 8, thus avoiding any impact on the sowing depth. By using a vertical spatial distribution of deep fertilization and shallow planting, the phenomenon of burning seeds and seedlings is effectively avoided, improving fertilizer efficiency. Furthermore, during the operation of the ditching, planting, and fertilization mechanism 8, when encountering obstructions, the overload displacement adjustment rod 802 will passively retract, and the elastic support plate 803 will passively deform, thus achieving obstacle avoidance and effectively protecting the ditching, planting, and fertilization mechanism 8 from damage. The ditching, planting, and fertilization mechanism 8 is also longitudinally staggered, effectively reducing the possibility of previous crop straw entanglement. Finally, the hydraulic cylinder 902 is extended and retracted by the hydraulic valve body 13, causing the pressing mechanism 9 to contact the ground and flatten the planting ditch to retain moisture, achieving soil moisture retention only on the seedling strip. The disturbance effectively preserves the surface soil structure and straw cover between the sowing strips, minimizing water evaporation and runoff, resulting in good moisture retention. The machine features a modular design, allowing for quick installation of each functional module onto the contoured frame 1 via quick-release components. Tightening the bolts on the quick-release components releases the wedge blocks 12, enabling each sowing unit to float independently, absorbing micro-topographical undulations and ensuring consistent sowing depth per row. This makes row spacing adjustment and component replacement quick and easy. Furthermore, this device can complete multiple processes in a single field visit, including stubble cutting, cleaning, ditching, deep fertilization, precision sowing, soil covering, and compaction, saving time and labor and effectively improving planting efficiency.
