Abstract

The invention relates to a dual-wing rotary-cutting type shallow-tillage machine. Each shallow-tillage knife (11) of the shallow-tillage machine comprises two wing edges and a transition edge (13), the two wind edges are symmetrically arranged on the two sides of the transition edge (13), and each wing edge comprises a forward cutting edge (15) and a side cutting edge (14); the shallow-tillage machine further comprises a drag plate (12), depth wheels (1) and tillage depth adjusting mechanisms (3), the drag plate (12) is fixed on the rear portion of a rack (6), and the depth wheels (1) are connected with the rack (6) through the tillage depth adjusting mechanisms (3). The operating depth of the depth wheels (1) is adjusted through the tillage depth adjusting mechanisms (3), so that the scarifying depth is controlled; scarifying and weeding operation is conducted through rotary cutting action of the shallow tillage knives (11); meanwhile, the drag plate (12) is used for leveling the land, lateral displacement of straw and the soil is effectively decreased, blocking of machines and tools caused by the straw is effectively avoided, ground surface flatness is significantly improved, the surface soil unit weight is reduced, and the requirement for conservation tillage is basically met.

Description

technical field [0001] The invention belongs to the technical field of agricultural shallow loosening machines, in particular to a double-wing rotary cutting type shallow loosening machine used in conjunction with a tractor. Background technique [0002] In recent years, the northern part of my country has vigorously promoted the conservation tillage technology, which requires reducing soil disturbance as much as possible during topsoil operations to reduce unnecessary loss of soil moisture. The shallow loosening machine is a new surface soil operation tool in the conservation tillage technology. It can complete the tasks of loosening the soil, weeding, and leveling the land at one time, which is beneficial to the subsequent sowing operations. However, general shovel-type shallow loosening machines, such as the utility model patent CN 204090446U, discloses a new type of shallow loosening weeder. When carrying out shallow loosening weeding operations, the two rows of shallow ...
