A differential speed plot seeding device

Abstract

A differential-speed plot seeding device, including a seed storage mechanism, a seed metering mechanism, and a sorting mechanism. The seed storage mechanism includes a seed pouring funnel, a seed storage tube, a lifting lever and a lever base, which are used to put and store seeds, and the lifting lever It is used to drive the seed storage cylinder to lift upwards, and the seeds are filled; the seed metering mechanism includes a cone, a parallel inclined plate type seed transport grid, a differential transmission device and a stepping motor, and the stepping motor provides power, through the differential transmission The device realizes the differential rotation of the cone and the parallel inclined plate type seed grid, and the parallel inclined plate type seed grid is divided into multiple spaces by multiple parallel partitions; the sorting mechanism includes a seed collection funnel, a seed divider and a DC motor , the DC motor rotates at a high speed to evenly distribute the seeds falling from the seed opening into each row. The differential speed seeding method solves the problems of unevenness between rows and low precision; the use of parallel slanting plate seed transport grids to divide the space solves the problem of seed interruption caused by the presence of partitions in the seeding machinery.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a differential-speed plot seeding device. Background technique [0002] Community breeding is the basic means of cultivating and promoting fine crop varieties, developing fine varieties, and increasing crop yields. Improved varieties contribute about 50% to the increase in agricultural production in developed countries, but only about 30% to the increase in agricultural production in my country, in which community seeding plays a key role. The sowing of plots requires that within the specified length and width of the plot area, quantitative seeds should be sown evenly and accurately to each row. The sowing in the plot should be uniform, there should be no seeds in the interval between plots, and there should be no mixed seeding in different plots. [0003] At present, there are mainly two ways of sowing in my country's plots: artificial sowing and mechanical sow...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problems of non-uniform sowing and low precision existing in the seeding device on the existing plot sowing machinery, and provides a differential speed type plot seeding device, which can increase the speed of the cone while keeping the speed of the seed grid, forming The differential rotation of the cone and the seed grid plate solves the problems of uneven seed filling, uneven seeding between various rows, and low precision in the prior art, forms a continuous and uniform seed flow, and improves the seeding accuracy of the plot
