Description

Seedbed leveling mechanism Technical Field The utility model relates to the technical field of agricultural machinery, in particular to a seedbed leveling mechanism. Background Wheat and rape are important winter planting crops in Yangtze river basin, so that the dual-purpose sowing of rape and wheat can be realized, and the utilization rate of the machine can be effectively improved. In order to improve the production efficiency and the utilization rate of rape and wheat, the combined seeder is widely applied to rape and wheat seeding links, and can synchronously realize the processes of rotary tillage, ditching, seeding, fertilization and the like. However, in the actual production process of the existing combined seeder, under the working conditions of higher water content and sticky weight of soil, the fertilizer can be screwed to the depth of the soil by the rotary tillage cutter, so that the fertilizer cannot be fully absorbed by seeds, germination and seedling emergence are affected, and weak seedlings are caused. The prior art provides a combined seeder with both base fertilizer and top fertilizer (such as the patent with publication number CN 119096737A), which solves the problems, but because the combined seeder is provided with a soil scraping plate for leveling soil, the soil scraping plate needs to be closely attached to the ground in order to ensure the leveling effect in actual use, so that the soil scraping plate can apply pressure to the soil when the soil is leveled, thereby compacting the soil too tightly, affecting the water permeability and air permeability of the soil layer and affecting the growth of seeds. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides a seed bed leveling mechanism, soil is cut through a disc harrow, rotary tillage is carried out by rotary tillage blades to break up and scatter the soil, meanwhile, ditchers on two sides of the rotary tillage are used for digging compartment ditches on two sides of the seed bed along the soil cutting track of the disc harrow, the harrow is used for carding the soil after rotary tillage for one time, large protruding soil blocks, rice stubble and the like are combed and pressed down, a soft elastic soil leveling plate is used for scraping and leveling the scattered soil, and the soft elastic soil leveling plate can avoid hard extrusion of the soil due to the characteristics of the soft and elastic property of the soft elastic soil leveling plate, so that the soil is prevented from being compacted and agglomerated, the water permeability and the air permeability of the soil are further ensured, and good conditions are provided for seed growth and development.
