Background
The no-tillage furrow opener is a key part of a no-tillage seeding machine, and is the key for forming a suitable seedbed and ensuring the spacing of seed and fertilizer and the consistency of seeding depth. Under the new situation, high-speed accurate seeding puts higher requirements on the soil adaptation and seedbed preparation capability of the no-tillage furrow opener.
The no-tillage fertilizing, seeding and furrowing operation generally needs to complete the procedures of hard stubble furrowing, fertilizing, soil returning and covering, seeding, soil covering and seed covering, rolling and the like in sequence. In order to avoid mutual influence of fertilization and seeding, the prior no-tillage seeding machine mostly adopts the front and back staggered arrangement of the independent fertilization furrow openers and seed sowing furrow openers in the structural arrangement, so that the longitudinal size of the no-tillage seeding machine is large, and the control of the distance between seed and fertilizer and the depth of seeding and fertilization is difficult. The problems can be well solved by adopting the same furrow opener to synchronously fertilize and sow. For example, the 'no-tillage deep scarification seed fertilizer vertical layering seed application furrow opener' with the patent number of 200810137873.1 realizes seed fertilizer separation by utilizing sequential natural collapse and earthing of furrow walls, has a simple structure, but can cause the seed fertilizer to be mixed together due to untimely earthing for clay or hardened soil, and has the problem of 'seed burning'. The integral no-tillage seeding furrow opener with patent number 201410436573.9 is beneficial to forming a good seedbed by respectively arranging a fixed horizontal cutter and a vertical shaft type stubble breaking and soil breaking device at the front and the rear of the furrow opener, but the rear fertilizing furrow opener and the seed discharging furrow opener still rely on natural soil return to ensure the distance between seed and fertilizer, and are not suitable for high-speed operation and clay-field seeding operation. The 'seed manure layering, spacing, dislocation and simultaneous application furrow opener' with the patent number of 201210458474.1 and the 'sowing and fertilizing device with active earthing' with the patent number of 201720472703.3 utilize the mode of arranging the soil guide plate in the ditch to realize the separation of seed manure, but the soil return mode is easily influenced by the moisture content of soil, the loosening degree of soil blocks, the operation speed of a machine and the like, the soil return amount between the seeds and the fertilizer and the earthing of the seeds are not enough, and the phenomenon of mixed application and seedling burning or seed exposure of the seed manure is caused.
In addition, functional components such as ditching, fertilizing and seeding of the no-tillage furrow opener are mostly connected in a welding mode, damaged parts are difficult to replace or function combination is difficult to carry out, when partial damaged functional components need to be replaced, or no-tillage fertilizing and seeding, independent fertilizing or seeding operation under different soil conditions (namely different soil types or water contents) needs to be carried out, a whole set of no-tillage furrow opener needs to be replaced or different types of seeders need to be equipped, and the utilization rate of machines is low.
