Wheat drill seeder single body suitable for sticky and heavy soil of rice stubble field and planting method

Abstract

The invention discloses a wheat drill seeder single body suitable for sticky and heavy soil of a rice stubble field and a planting method. The wheat drill seeder single body comprises a rack, and a horizontal shallow rotary tillage mechanism, a floating soil crushing and leveling mechanism, a vertical deep stubble cutting mechanism, a ditching, fertilizing and seeding mechanism and a floating soilcovering and pressing mechanism are sequentially installed on the rack from front to back; the horizontal shallow rotary tillage mechanism conducts stubble cutting and soil crushing in the advancingdirection on shallow soil, then the floating soil crushing and leveling mechanism conducts profiling soil crushing and leveling on the surface layer of the soil, and then the vertical deep stubble cutting mechanism conducts stubble cutting and soil crushing on the shallow soil and deep soil; then a ditching and fertilizing device ditches and fertilizes at the same time, a ditching and seeding device ditches and seeds at the same time, and the seeding manner of seeding, fertilizing and seeding alternating and shallow seeding and deep fertilizing is achieved; and then, a floating soil covering device performs profiling soil covering on fertilized and sown ditches, and finally, a floating adjustable pressing device performs profiling compaction on the surfaces of the ditches after soil covering, so that high-performance compound seeding operation of the sticky and heavy soil of the rice stubble field is realized.

Description

technical field [0001] The invention belongs to a wheat seed drill, and in particular relates to a single wheat seed drill suitable for sticky and heavy soil in rice stubble fields and a planting method. Background technique [0002] Wheat drill is one of the key equipment for crop planting in Jiangsu rice-wheat rotation area. During the wheat sowing period, there are many regional problems such as prominent stubble connection contradictions, difficult cultivation of sticky and heavy soil in rice stubble fields, difficulty in returning large amounts of straw to the field, and easy waterlogging in dry farming. At the same time, there are great differences in production methods and mechanization technologies in different regions, different stubbles, and different varieties of rice-wheat rotation areas, which further increases the difficulty of research on high-efficiency wheat seeding equipment. At present, there are few types of wheat seed drills suitable for Jiangsu rice-wh...

Problems solved by technology

[0005] With the breakthrough of wheat precision seeding technology, combined seeding operation technology and the application and promotion of machinery and tools in our province, the problems of hanging grass blocking, racking and drying of traditional no-tillage seeding equipment have been completely solved. Wheat Some progress has been made in the research of seed drills, but the existing implements have insufficient adaptability to the sowing operation in sticky and heavy soil in rice stubble fields, and there are problems such as high operating cost, poor soil crushing effect, easy congestion, insufficient soil compaction, etc. The application of intelligent technology such as seeding technology and machine tool intelligence technology is still relatively low, and the operating efficiency still needs to be improved
