V-shaped adjustable soil covering and pressing device of seeder

Abstract

The invention relates to a V-shaped adjustable soil covering and pressing device of a seeder, and belongs to the field of agricultural machinery. The V-shaped adjustable soil covering and pressing device of the seeder comprises a rack, a soil crushing mechanism and a pressing mechanism. The soil covering and pressing device of the seeder is of a symmetrical structure, soil crushing mechanisms are arranged at the two ends of the front side of the lower portion, the soil covering and pressing device is installed at the starting end of the lower portion of a rack, a pressing mechanism is arranged at the rear end of the lower portion, during operation, the rack is dragged by an engine to work forwards, the soil crushing mechanisms rotationally crush soil and extrude the soil to the front end of the pressing mechanism, and then the pressing mechanism rotationally presses the soil. The working method that the soil crushing mechanism crushes soil and extrudes the soil and the pressing mechanism presses the soil is adopted, the soil is evenly covered on the seed rows, soil impurities are avoided, it is ensured that the soil covering and pressing strength of the seeds is uniform and consistent, the seed germination rate is increased, and the probability of large and small seedlings of the seeds is reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a V-shaped adjustable soil-covering suppressing device for a seeder. Background technique [0002] In view of the cyclic operation of the current soil cultivation mode, the soil active soil layer becomes shallow and the plow bottom layer is hard, resulting in a large number of clods when ploughing the land, which makes the seeder affected by soil impurities such as large clods, straws, etc. etc., making the seed row uneven, affecting the plant spacing, thereby reducing the emergence rate. Therefore, there is an urgent need to provide a new type of soil-covering suppressing device, which can break up soil impurities, and then ensure that the covering soil thickness is consistent, the suppressing strength is suitable, and the seed bed is leveled to solve the above problems. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned shortcomings of the prior art, the p...

Problems solved by technology

[0002] Aiming at the current cycle operation of soil tillage farming mode, the active soil layer of the soil becomes shallow and the plow bottom layer is hard, resulting in a large amount of soil clods when plowing the land, so that the seeder is affected by soil impurities when covering the soil, such as large clods of soil, straw etc., making the seed rows uneven and affecting the plant spacing, thereby reducing the emergence rate
