Description

Technical Field

[0001] The present invention belongs to the technical field of rotary tillage sowing equipment, and in particular to a rotary tillage sowing and furrowing integrated machine with double rollers cooperating to achieve equal sowing depth. Background Art

[0002] The rotary tillage sowing and furrowing machine is an agricultural machinery equipment integrating rotary tillage, sowing, pressing and furrowing. The existing rotary tillage sowing and furrowing machine includes a frame, which is driven forward by the existing walking mechanism. The frame is provided with a rotary tillage mechanism, a furrowing mechanism, a sowing mechanism and a pressing roller group in sequence. The rotary tillage mechanism includes a rotating shaft and a plurality of rotary tillage blades arranged outside the rotating shaft. The rotary tillage gear box can drive the rotary tillage blade shaft to rotate, thereby driving the rotary tillage blades to rotate and rotary till the land; the furrowing mechanism includes two notched discs respectively arranged on both sides of the frame. When the frame moves, the notched discs dig and form furrows on the ground on both sides of the frame, and a field ridge higher than the furrow is formed between the two furrows. The sowing mechanism includes a plurality of double disc furrowing devices and a seed feeding mechanism. The pipe mouth of the seed feeding mechanism is arranged at the rear end of the double disc furrowing device. After the double disc furrowing device completes the furrowing of the planting furrow, the seed feeding mechanism controls the seeds to fall into the opened planting furrow, and then the pressing roller is used to complete the covering and leveling.

[0003] In the process of using the traditional rotary tillage sowing and furrowing machine, the rotary tillage blade of the rotary tillage mechanism tills a layer of soft and broken soil, and then the double disc furrowing device furrows the planting grooves. The seed feeding mechanism controls the seeds to fall into the opened planting grooves, and then the pressure roller is used to complete the soil covering and leveling. However, the seeds fall directly into the soft planting grooves, which is not conducive to the root system of the seeds attaching to the soil during germination.
