AI Technical Summary
Technical Problem
[0006]为了解决现有技术的不足，本发明提供了旱地小麦双轴播种机的旋耕-镇压一体化仿形轮组；从而解决了传统镇压装置因动力分离导致镇压滞后、压力不可调且地形适应性差，造成土壤失墒严重和出苗不齐的问题
Benefits of technology
[0009] 1. The contour wheel assembly in this invention sequentially performs soil covering, soil compaction, and ditching treatment on the sides of the sowing area during movement. The front soil covering wheel can achieve leveling of the wheat sowing area and can also refine some soil and backfill it above the sowing layer, improving the uniformity of soil density during compaction. In addition, the fine soil can form a buffer layer between the seeds and soil clods, preventing the soil clods from squeezing and damaging the seeds during subsequent compaction, thus improving the integrity of the seeds and the subsequent survival rate.

Abstract
The rotary tillage-pressing integrated profiling wheel of the dryland wheat double-axis seeder belongs to the technical field of agricultural machinery, and the profiling wheel comprises a seeder comprising a traction assembly and a three-section three-dimensional profiling wheel set. The pressing wheel rotation speed is made to be ahead of the rotary tillage shaft through power coupling technology to eliminate soil rebound and avoid efficiency loss caused by secondary operation. The three-section three-dimensional profiling wheel set, in combination with a pressure self-adaptive adjusting mechanism, can dynamically adjust the pressing intensity and the wheel surface inclination angle, adapt to complex terrains and straw returning conditions, and realize accurate pressing on demand. The technology breaks through the functional limitations of traditional pressing devices, is expected to solve the problems of uneven emergence and resource waste, and promotes the upgrading of dryland wheat planting towards high efficiency and precision.
