Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery, and in particular relates to an integrated machine for strip tillage, land preparation, fertilization and ridging in low-lying areas under the straw rowing mode. Background Technology
[0002] Currently, mainstream strip tillage machinery on the market uses rotary blades to shallowly till the soil in the seed strip. However, due to insufficient working depth, it's difficult to break up the plow pan. Strip tillage machinery imported from the US, which uses a chisel-like shovel as its main tillage component, also doesn't break up the soil sufficiently after tillage. Furthermore, the seed strip and straw mulch strip are essentially at the same height after both types of machinery, hindering rapid soil temperature rise after sowing. This is especially problematic in low-lying, waterlogged areas where the soil moisture is high and dissipates slowly, resulting in poor applicability of current machinery and severely limiting the technology's application. Additionally, these two types of machinery cannot create ridges after land preparation, leading to poor drainage during the corn growing season and increasing the risk of waterlogging, which can cause yield reduction or even crop failure in severe years. Therefore, innovating machinery to complement straw return in low-lying areas is of great significance for improving the applicability of this technology. Summary of the Invention

The strip tillage mechanism is used for deep tillage of the soil in the sowing zone, the soil breaking mechanism is used to break up the clods formed after strip tillage, the straw pulling and rowing mechanism is used to clear the straw from the edge of the sowing zone outwards, the ridging and compaction mechanism is used to rid and compact the collected soil, and the fertilization mechanism is used to automatically sow seeds in the sowing zone.

[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] This invention relates to an integrated machine for strip tillage, land preparation, fertilization, and ridging in low-lying areas under a straw rowing mode. When the strip tillage mechanism tills the seeding strip, the tillage shovel operates at a deep depth and easily breaks up the plow pan through high-speed rotation. The fertilization mechanism can apply base fertilizer while tilling, and the base fertilizer and soil can be fully mixed under the action of the strip tillage mechanism. The semi-soil-breaking strips on the soil-breaking mechanism are densely and reasonably arranged, which has a good effect on breaking up the tilled soil.

Each set of two straw-removing and rowing mechanisms can simultaneously clean the straw at the edge of the seeding strip and collect the soil in the seeding strip. The ridging and compaction mechanism can simultaneously rid the two seeding strips and compact the straw in the straw rowing and covering strip between the two seeding strips.

[0030] The specific working method is described below using specific embodiments:
[0031] like Figures 1 to 11As shown, a straw-rowing integrated machine for strip tillage, land preparation, fertilization, and ridging in low-lying areas is connected to a tractor via a lower traction plate 112 and a suspension front rod 111. It operates by relying on the tractor's power and provides torque to the gearbox 11 via the tractor's rear output shaft. This torque is then transmitted to a small sprocket 8 via a flange sleeve coupling 12, a strip tillage drive shaft 13, and a circular flange bearing seat 14. The small sprocket 8 transmits power to a large sprocket 9 via a chain. The large sprocket 9 drives the strip tillage long shaft 205, causing the strip tillage mechanism 2 to rotate rapidly backward. The tillage shovel 206 performs deep tillage on the soil in the seeding zone. Simultaneously, the fertilization mechanism 6 applies fertilizer from the fertilizer tank 601 to the tilling seeding zone via an electronic fertilizer applicator 603, achieving full-layer mixing of soil and fertilizer. Subsequently, the installation positions of the displacement square tube 302 and the soil-breaking adjustment tube 303 of the soil-breaking mechanism 3 are adjusted so that the soil-breaking shaft 304 and the second... The assembly of sixteen semi-crushing soil strips 305 is at a reasonable height and rotates by friction with the ground to break up the soil clods formed after strip tillage. Different sizes of semi-crushing soil strips 305 can be replaced according to the soil quality of the work site to achieve the best soil breaking effect. Next, adjust the installation position of the shifting square tube 302 and the straw-pulling and soil-returning adjustment tube 402 of each set of left and right straw-pulling and row-returning mechanisms 4 to make the height of the straw-pulling wheel 404 and the soil-returning wheel 408 reasonable. The inner soil-returning wheel 408 gathers the broken soil inward, and the outer straw-pulling wheel 404 clears the straw at the edge of the sowing strip outward. Finally, adjust the installation position of the pressing and ridge-forming adjustment tube 501 of the ridging and compacting mechanism 5 to make the height of the pressing and ridge-forming shaft 502 appropriate. It then uses friction with the ground to rid and compact the gathered soil, while compacting the straw in the straw-returning and covering strip.
