Large-ridge double-row buckwheat sowing machine

Abstract

The invention discloses a large-ridge double-row buckwheat sowing machine, which comprises a frame, a seed box and a fertilizer box are arranged over the frame, an operation mechanism with 1-6 ridges is arranged at equal interval under the frame, the operation mechanism of each ridge comprises a fertilize opener, two sowing openers and a ; the fertilize opener of each ridge is arranged at the front part of the frame, two sowing openers are arranged at the rear part of the fertilize opener, the repressing roller is arranged at the rear part of two sowing openers; each fertilize opener is communicated with a fertilizer shifting device arranged at the bottom of the fertilizer box through a fertilizer discharge pipeline; each sowing opener is communicated with a seed shifting device arranged at the bottom of the seed box through a seed discharge pipeline; and the fertilizer shifting device and the seed shifting device are connected by driving a repressing shaft, a sprocket wheel, a chain and a transmission shaft through the repressing roller. The large-ridge double-row buckwheat sowing machine has the advantages of simple structure, uniform seed falling, consistent depth and good operation quality, and can realize the large-ridge double-row sowing.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a double-row buckwheat planter with large ridges. Background technique [0002] Buckwheat belongs to the genus Buckwheat in the family Polygonaceae, with a plant height of 60-100 cm and a maximum height of about 150 cm. The leaf axils of the main stem nodes can grow primary branches, and the leaf axils of the primary branches can grow secondary branches. Tertiary branches can be grown under certain cultivation conditions. In the north where one season is planted, sowing is usually done from late May to early June. Since there is no special double-row buckwheat seeder for large ridges, single-row seeders are generally used for single-row sowing of small ridges. The shortcoming of small ridge single-row sowing is: 1) buckwheat enters the budding period, and due to the increase of branches, the furrows are closed, and the ventilation and light transmission are not go...

AI Technical Summary

Problems solved by technology

The disadvantages of single-row sowing in small ridges are: 1) buckwheat enters the budding stage, due to the increase of branches, the furrows are closed, the ventilation and light transmission are not good, which affects the vegetative growth, reproductive growth and bee pollination activities of buckwheat, and the seed setting rate decreases

2) Intertillage and fertilization operations cannot be carried out, which seriously affects the yield of buckwheat
