Wheat seeder

Abstract

The invention discloses a wheat seeder, which is used for realizing no-tillage seeding. The wheat seeder comprises a rack, a fertilizer applying mechanism, a seeding mechanism and a compaction mechanism, wherein the rack comprises a front beam, a middle beam and a rear beam; the fertilizer applying mechanism comprises a fertilizer box, a fertilizer discharge pipe and a front drill barrowing leg; the seeding mechanism comprises a seed box, a front seed discharge pipe, a rear seed discharge pipe, a middle drill barrowing leg and a rear drill barrowing leg; the wheat seeder is characterized in that the front drill barrowing leg is connected with the front beam through an elastic component, the middle drill barrowing leg is connected with the middle beam through an elastic component, and the rear drill barrowing leg is connected with the rear beam through an elastic component; the compaction mechanism comprises a group of compaction wheels and a group of dispersers; the compaction wheels and the dispersers are arranged on the same transmission shaft; and one disperser is arranged between two adjacent compaction wheels. According to the wheat seeder, the technical problems existing in the conventional no-tillage seeder are solved, so that the sprouting rate and the survival rate after wheat seeding are guaranteed, the working efficiency of seeding is obviously increased, and the wheat seeder has broad promotion and application value.

Description

Technical field [0001] The invention relates to an agricultural planter, in particular to a wheat planter that does not require rotary tillage of the land, and belongs to the technical field of agricultural seeding machinery. Background technique [0002] The structure of the existing wheat planter mainly includes the front fertilizing columbine legs fixed on the front beam of the frame, the rear seeding columbine legs and the compaction wheel fixed on the rear beam of the frame. Because the front fertilizing columbine legs and the rear seeding columbine legs are both The structure is vertically downward, and the rear sowing columbine legs are densely distributed on the rear beam of the frame, which will cause congestion of firewood during fertilization and sowing, and it is impossible to realize non-tillage sowing of wheat. [0003] In order to solve the above problems, a wheat no-tillage planter with Chinese patent number ZL201120446074.X discloses a two-row seeding columbine str...

AI Technical Summary

Problems solved by technology

However, wheat is generally planted on the land after the harvest of autumn crops. Since the stalks of autumn crops are crushed and cover the surface of the land, when the above-mentioned non-rotary tillage seeder is used for sowing operations, the stalks bonded together cannot be dispersed, giving The growth of wheat is adversely affected; at the same time, because the land has not been plowed and harrowed, and the straw cannot be evenly covered, the land is uneven, and the legs and frame of the above-mentioned non-rotary tillage planter are fixed assemblies. structure, the ditch openers located at the lower end of the columbine legs have different ditch depths, making the seed burial depths inconsistent, and it is difficult to ensure the germination rate and survival rate of wheat after sowing; The columbine legs and the six seeding columbine legs in the middle and rear rows can complete the sowing operation of six rows of wheat at the same time, and the work efficiency needs to be further improved
