Soil preparation mechanism for wheat drill seeder suitable for sticky and heavy soil of rice stubble field

Abstract

The invention discloses a soil preparation mechanism for a wheat drill seeder suitable for sticky and heavy soil of a rice stubble field. The soil preparation mechanism 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 soil covering 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 advancing direction 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 cuttingmechanism conducts stubble cutting and soil crushing on the shallow soil and deep soil; and through combined use of the horizontal shallow rotary tillage mechanism and the vertical deep stubble cutting mechanism, an in-situ tillage and soil breaking treatment technical scheme is formed, the rice and wheat crop rotation planting system and agricultural requirements of typical regions of Jiangsu aremet, and high-performance compound seeding operation of the sticky and heavy soil of the rice stubble field is achieved.

Description

technical field [0001] The invention relates to a wheat seed drill, in particular to a field preparation mechanism for a wheat seed drill suitable for sticky and heavy soil in rice stubble fields. 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-wheat rot...

AI Technical Summary

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 machines and tools have insufficient adaptability to the sowing operation in sticky and heavy soil in rice stubble fields, and there are problems such as high operating costs, poor soil crushing effect, and easy congestion. The level of intelligent technology is still low, and the application of intelligent technology has just started, and the operating efficiency needs to be improved
