Problems solved by technology

However, when the above-mentioned no-tillage seed drill encounters the sowing environment of the muddy field (that is, the farmland with more than saturated water content), due to the muddy and loose soil in the field, the ground wheel mechanism is very easy to sink into the field mud and cannot rotate continuously and regularly. As a result, the seed metering device and fertilizer discharge device driven by it cannot rotate continuously and regularly, causing the phenomenon of seed and fertilizer discharge in the field gap, which seriously affects the quality of sowing farming
Obviously, the above-mentioned no-tillage seed drill driven by the ground wheel mechanism for seed and fertilizer discharge cannot achieve precise seeding, nor can it be applied to sowing operations in muddy fields

Abstract

The invention discloses a no-tillage precision seeder. The no-tillage precision seeder comprises a rack hung on an agricultural motor vehicle; a seeding mechanism, a rotary tillage mechanism and a fertilization mechanism are arranged on the rack, wherein the seeding mechanism is mainly composed of a seed box, a seed metering device arranged at a seed metering opening in the seed box in a rotatablestructure and a seed metering pipe connected to the seed metering device; the fertilization mechanism mainly comprises a fertilizer box, a fertilizer feeder which is arranged at a fertilizer openingin the fertilizer box in a rotatable structure, and a fertilizer pipe which is connected to the fertilizer feeder; and the rotation actions of the seed metering device of the seeding mechanism and a fertilizer feeder of the fertilzation mechanism are respectively controlled by a driving motor on the rack. The no-tillage precision seeder can drive the seed metering device of the seeding mechanismand the fertilizer feeder of the fertilization mechanism without depending on the rotation of a land wheel mechanism, that is, the seed metering device of the seeding mechanism and the fertilizer feeder of the fertilization mechanism can be rotated for seeding without taking the field ground environment as a condition, the precision seeding can be continuously and stably realized, and the phenomenon that seeding and fertilization are discontinuous in the field is avoided.

Description

technical field [0001] The invention relates to a no-tillage drill, in particular to a no-tillage precision seeder capable of accurately and stably discharging seeds in a seed box and fertilizers in a fertilizer box into the field, which is especially suitable for sowing operations in muddy fields . Background technique [0002] No-till drill is an agricultural instrument that replaces manual labor and completes the steps of rotary tillage, sowing, and fertilization step by step. It has technical advantages such as efficient operation and standardized sowing, and has been widely used in agricultural production. [0003] At present, the common no-till drill is mainly composed of a frame towed on agricultural vehicles (such as tractors, etc.), a rotary tiller arranged on the front side of the lower part of the frame, and a ground wheel arranged on the rear side of the lower part of the frame. It consists of a mechanism, a seeding mechanism and a fertilization mechanism arrang...
