Abstract

The invention provides a rotary type scarification device for a no-till sowing machine, and belongs to the technical field of agricultural machinery. The rotary type scarification device mainly aims to achieve the purposes of deep scarification, correct placement and deep placement, comprises a rack and a gutter-plough for fertilization and is characterized by further comprising a transmission speed change assembly arranged in the middle of the rack, a scarification knife assembly which is arranged on the rack and is located in front of the gutter-plough for fertilization and a front soil processing device, the scarification knife assembly comprises a short scarification knife and a long scarification knife which are vertically parallel to each other and arranged side by side, a first set of curved knife teeth at the lower end of a long knife rod of the long scarification knife are curved downwards and are fixedly connected to the long knife rod, other sets of curved knife teeth are curved upwards, are arranged at intervals in the length direction of the long knife rod and are in occlusion with downward-curved knife teeth of the short scarification knife, and the long scarification knife can go deep into the soil by 200 mm to 300 mm in the length direction. The transmission speed change assembly converts the horizontal power for pulling a device into the rotating force of the scarification knife assembly in the vertical direction.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a rotary loosening device for a no-tillage seeder. Background technique [0002] According to the traditional farming method, people must plow and level the land before sowing, and then put the seeds into the ridges. Then, using the no-tillage live broadcast method, the land is not plowed, and the surface is covered with a layer of straw and weeds. How to sow seeds? The usual method is to refit the seeder with a small plowshare, which pushes the straw layer to a depth that just touches the soil, and then spreads the seeds into the topsoil. Because the surface soil has been covered by straw and weeds for a long time, it is generally very moist, and the microorganisms are rich, and the soil quality is relatively soft. After the seeds are sown, they will germinate relatively quickly and take root easily. After the seeds germinate, the straw and weeds on ...
