Description

Technical Field

[0001] This invention relates to the field of spacing adjustment device technology, specifically to an adaptive row spacing adjustment device for a wheat planter. Background Technology

[0002] Wheat, as one of my country's major grain crops, is directly affected by the quality of its sowing, which in turn impacts its subsequent growth and final yield. Row spacing is a core planting parameter in wheat sowing operations, and different soil conditions, climates, wheat varieties, and planting patterns result in significantly different row spacing requirements. A reasonable row spacing configuration ensures that wheat plants receive sufficient sunlight, water, and nutrients, reduces competition among plants, improves the overall growth quality of the plant population, and ultimately achieves the goal of increased yield and income. Therefore, the row spacing adjustment function of the seeder is crucial for adapting to diverse planting needs and improving the versatility and precision of sowing operations.

[0003] Currently, most wheat planters use manual adjustment for row spacing. This requires operators to stop the machine, disassemble or replace parts (such as adjusting connectors between individual planters or changing planter trays with different spacing) to adjust the row spacing, and then restart the machine. This manual adjustment method is not only cumbersome and time-consuming, but its accuracy also depends heavily on the operator's experience, making it prone to row spacing deviations and affecting planting quality. Furthermore, manual adjustment cannot be performed in real-time during planting; when different plots require different row spacing, multiple stops are necessary, significantly reducing planting efficiency and increasing operating costs.

[0004] In summary, a row spacing adaptive adjustment device for wheat seeders is needed to solve the above problems. Summary of the Invention

By setting a soil covering component, soil can be covered after sowing, thus covering the sowing holes with soil. This soil covering operation can be performed during sowing, integrating it with the sowing process, eliminating the need for separate soil covering and improving overall efficiency.

[0041] The overall working principle is as follows: In use, the rectangular card plate 31 is inserted into the rectangular slot 35. At this time, the first threaded rod 37 is inserted into the first insertion hole 32 and the second insertion hole 36. At this time, the first fixing nut 38 is tightened and fixed to the first threaded rod 37. At this time, the rectangular card block 43 is fixed to the rectangular card frame 42, and then the second threaded rod 46, the third insertion hole 44, and the fourth insertion hole 45 can be inserted, and the second fixing nut 47 is locked to the second threaded rod 46. At this time, the row spacing value is pre-entered into the control cabinet 2, and then, in conjunction with the central processing unit 6, the distance sensor 323 can transmit the distance information to the central processing unit 6 through the information transmission module 12 during the driving process. Then, the information judgment module 7 processes the row spacing information, and then controls the start and stop of the first motor 314. The first motor 314 can drive the rotating rod 315 to rotate, which in turn drives the transmission gear 319 to rotate, which in turn drives the rack plate 312 and the rectangular slider 310 to move along the rectangular slide groove 39, which in turn drives the rectangular moving frame 311 and the quantitative feeding component 4 to move, thereby controlling the sowing row spacing. At this time, the second motor 413 is started, so that the auxiliary rotating rod 414 can drive the screw feed rod 415 to rotate, which can then cooperate with the discharge pipe 410 to perform the discharge operation. The third motor 53 is started, which causes the transmission rod 54 to drive the half gear 55 to rotate. When the gear surface of the half gear 55 rotates to the side of the full gear 57, it can drive the full gear 57 and the driven rotating rod 56 to rotate, which in turn causes the torsion spring 59 to deform. At this time, it can drive the arc-shaped shovel plate 511 to rotate, thereby performing the soil covering operation. When the non-gear surface of the half gear 55 rotates to the side of the full gear 57, it can be reset under the action of the torsion spring 59.
