Abstract

The invention relates to a spring-tooth retractable intertillage soil loosening and weeding unit and belongs to the field of agricultural machinery. Driving land wheels, eccentric sliding way driven spring-ring retractable soil loosening and weeding cylindrical drums, cam driven spring-tooth retractable soil loosening and weeding conical drums and hiller assemblies are assembled on a unit frame, the driving land wheels are connected with the eccentric sliding way driven spring-ring retractable soil loosening and weeding cylindrical drums through driving sprockets, chains, driven sprockets, main driving shafts, driving bevel gears, driven bevel gears and cylindrical drum driving shafts, the eccentric sliding way driven spring-ring retractable soil loosening and weeding cylindrical drums and the cam driven spring-tooth retractable soil loosening and weeding conical drums are located on two sides of a seedling row, axial lines of the cylindrical drum driving shafts are in parallel with the seedling row, and conical drum supporting shafts are perpendicular to the seedling row. The unit adopts the scheme of transverse in-row weeding and longitudinal ridge weeding, and has the characteristics of novel and reasonable structure, good intertillage soil loosening and weeding effect, low seedling injury rate, high universality degree and strong applicability.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical intertillage loosening and weeding operation assembly. Background technique [0002] In recent years, with the development of green organic agriculture, the "three reductions" policy of reducing the application of chemical fertilizers, pesticides, and herbicides has been put forward, and the research and development of mechanical cultivating tools has become a hot spot of concern. Especially in my country's green organic agricultural production base - Heilongjiang Province, the response is more prominent. However, when the existing mechanical cultivating implements perform soil loosening and weeding operations in the field, the effect is not ideal, or the weeding rate is low, or the seedling injury rate is high, especially when operating in the area between adjacent seedlings, it is more difficult. Big. How to effectively and reliably complete intertillage loosening a...
