Cell seeder and automatic seeding method based on satellite positioning

Abstract

The invention relates to a cell seeder and an automatic seeding method based on satellite positioning. The plot seeder includes automatic seed feeding device, six-point seeding device, continuous seeding device, single-row seeding device, ditching seeding device and self-propelled chassis; automatic seed feeding device, six-point seeding device, single-row seeding device 1. The ditching seeding device is installed in the middle of the self-propelled chassis from top to bottom; two continuous seeding devices are installed in the front of the self-propelled chassis, located in front of the six-point seeding device. The invention can automatically control the plot seeder according to the longitude, latitude and speed information of satellite positioning received in real time, complete the automatic seed supply, drop and sorting operations of the plot at one time, realize the switch between plot seeding and continuous sowing mode, and accurately control the plot Longer, improve sowing uniformity, reduce operating procedures, reduce labor intensity, and improve utilization efficiency.

Description

technical field [0001] The invention relates to a cell seeder based on satellite positioning and an automatic seeding method, belonging to the technical field of agricultural machinery. Background technique [0002] Field breeding experiment is a small-scale experiment for cultivating new varieties and breeding improved varieties. It is the basic means to develop high-quality improved varieties and increase crop yield. Plot seeding is a key link in field breeding experiments, which has a very important impact on the scientificity and accuracy of breeding experiments. On the basis of meeting the requirements of field sowing, plot sowing has special requirements such as quantitative sowing, fixed-length sowing, and interval sowing. [0003] At present, the plot seeders in our country are mainly driven by mechanization, and the automation level is not high. In the existing mechanical sowing operation method, firstly, manual marking is carried out according to the length and i...

AI Technical Summary

Problems solved by technology

Therefore, manual marking and auxiliary seeding require high manual proficiency, high labor intensity, difficulty in grasping the accuracy of the sowing length of the plot, and poor uniformity of the initial border of the plot; the movement of the seeding device of the plot planter uses ground wheels or driving wheels Through the mechanical drive components such as sprockets and gearboxes, the mechanical transmission ratio needs to be adjusted each time to meet the speed requirements of the cone grids in different length plots. At the same time, it is easily affected by the field soil, and there are problems such as ground wheel slippage and sprocket vibration. The seeding performance of the plot seeder is affected, and the seeding quality is poor

At the same time, because the plot seeder belongs to the special seeder for scientific research institutes and breeding companies, the price is relatively expensive, dozens of times that of the general field seeder, but the traditional plot sowing machine can only realize the plot seeding operation with a small amount of sowing. The rate is low, which will cause waste of machines and tools for a long time
