Combined type ditcher for wheat sowing

Abstract

The invention relates to a combined type ditcher for wheat sowing, and in particular relates to a compound ditcher which can realize wheat sowing based on uniform width, adjustability of the width in a certain range and separate applications of seeds and fertilizers. The ditcher is structurally characterized in that the penetrating wedge angle of a shovel body of the ditcher is 30 degrees; the curvature radius R of the soil breaking frontal line of the shovel body is 150-300mm; the width of the shovel body is 90-130mm; the width of the inner cavity is 80-120mm; the included angle between the lower edge of the shovel head part and the horizontal plane is 1-3 degrees and the included angle between the lower edge of the shovel body behind the orifice of a fertilizer pipe and the horizontal plane is 3-6 degrees, so the shovel body rises by 20-30mm relative to the shovel head; the fertilizer pipe of the ditch is arranged in front of seed pipes and is welded together with the inner cavity of the shovel body; the seed pipes are welded at the left and right sides of the fertilizer pipe; and the rear parts of side plates of the shovel body of the ditch, upper guard plates at the orifices of the seed pipes and a scatter plate form a wheat wide sowing device assembly.

Description

technical field [0001] The invention relates to a combined opener for wheat sowing, which can realize uniform sowing of wheat in a wide width and can be adjusted within a certain range, and is a compound opener capable of distributing seed and fertilizer. Background technique [0002] Wheat wide-width planting is a new planting agronomic method that has emerged in recent years. Conventional seeders are difficult to meet its requirements. The main problem is that there are defects in the design of the openers. The general openers are mainly suitable for linear sowing. The operation needs, that is, the seeds are distributed in a linear manner, while the wide-width sowing requires the seeds to be distributed in an equilateral triangle, or distributed in two lines in one opener, so that two openers are required at the same time to complete the wide-width sowing operation . In addition, the existing wheat seeder is used in agricultural production to undertake the simultaneous so...

Problems solved by technology

The sowing and fertilization of the former are completed by two different openers at the front and back. This opening method results in a large distance between the fertilizer pipe and the seed pipe. Due to the influence of factors such as uneven terrain and operating machine travel errors, seeds and fertilization will occur. Fertilizer contact causes the seeds to be damaged by the fertilizer or the fertilizer efficiency is reduced if the distance is far away; the latter sowing and fertilization are realized through mechanical secondary ground operations, which not only crushes the soil multiple times, but also makes it more difficult to ensure the spacing of fertilizers

The improved no-tillage seeder is used for sowing in wide-width operations. One sowing tube (corresponding to one seeder) is used to sow two lines, resulting in uneven seed distribution within the width, which makes it difficult to meet the requirements of wide-width sowing operations.
