Droplet type rapeseed precision sowing device and sowing method thereof

Abstract

The invention provides a droplet type rapeseed precision sowing device and a sowing method thereof. The device comprises an air pump, an airway tube, an airbag, a feeding opening, a container, mixed liquid, a stirrer, a rotation shaft, droplet outlets, a pressure sensor and a control box, wherein the airbag is placed inside the container, and is linked with the airway tube through the air pump; the feeding opening is located at the upper portion of the container, and is used for adding the mixed liquid and rapeseeds into the container; the proportion of the mixed liquid is identical to that of the rapeseeds, so that the rapeseeds can evenly suspend in the liquid; the stirrer is placed inside the container, external power is transferred through the rotation shaft; the droplet outlets are located at the lower portion of the container, and the number and distance of the droplet outlets are determined by the number of sowing lines and line spacing of the rapeseeds; the pressure sensor is located inside the container, and is connected with the control box through a data line; the control box is linked with the air pump through the data line, and is used for commanding the sowing device to work. The droplet type rapeseed precision sowing device is simple in structure and small in mechanical noise and vibration; the line spacing and the line number are not influenced by a mechanical structure.

Description

technical field [0001] The invention relates to a rapeseed sowing technology, in particular to a droplet precision rapeseed sowing device and a sowing method thereof. Background technique [0002] As an important oil crop, rapeseed ranks first in the world in both its planting area and total output. my country's domestic demand for edible vegetable oil is increasing, and it has become the world's largest edible oil importer. Vegetable oil has become my country's largest agricultural product import item. The import dependence has exceeded 60%, and the self-sufficiency rate is less than 40%. At present, my country's rapeseed sowing is still dominated by traditional handwork, and labor costs account for 60-70% of production costs. [0003] Nowadays, rapeseed sowing methods at home and abroad are divided into manual sowing, pneumatic mechanical sowing and volumetric mechanical sowing. Manual sowing has low efficiency, low precision, strong randomness, and non-standard planting...
