Description

Technical Field

[0001] This utility model relates to the technical field of agricultural machinery, and in particular to a telescopic double-row hook deep tillage machine. Background Technology

[0002] Subsoilers, as core agricultural equipment for deep soil loosening, effectively increase rainwater infiltration rates and soil water retention, and are widely used in agricultural production. However, when operating in hilly areas, scattered plots, and other areas with complex terrain, uneven furrow distribution is a common problem, requiring frequent adjustments to the subsoil hooks to accommodate furrows with varying spacing. Traditional subsoilers require manual disassembly and reinstallation of the subsoil hooks for adjustment, a cumbersome and time-consuming process that reduces efficiency and increases operator workload, failing to meet the demands of flexible and efficient field operations. Furthermore, for hard soil, a double-row subsoil hook design is typically used, with the front row breaking the soil and the rear row further loosening it. However, traditional subsoilers require manual adjustment of the hooks on-site, which can lead to inaccurate alignment of the front and rear rows, affecting the subsoiling effect.
