Peanut sowing seed-metering device with adjustable particle size

Abstract

The invention provides a peanut sowing seed-metering device with adjustable particle size. The peanut sowing seed-metering device comprises an adjusting disc, a discharge plate, elastic baffles and a fixing bolt. The adjusting disc and the discharge plate are fixedly connected through the fixing bolt, so that the friction between seeds in inner cells and a shell of a seed box of the seeder is avoided, the seeds are protected, and the germination rate of the seeds is improved; the elastic baffles are clamped on a circumferential outer wall of the adjusting disc through elastic force, and are opposite to the positions of feed preparation holes one by one; two groups of positioning holes are formed in the adjusting disc, and are matched with positioning holes in the discharge plate respectively; and the device is suitable for seeding large peanuts when the elastic baffles are positioned at the feed preparation holes, and is suitable for seeding small peanuts when the elastic baffles are positioned at the inner cells, so that the classified seeding for seeds with different particle sizes is realized, the double grain rate and accuracy of the seeding are improved, the seeds of peanuts are effectively saved, and the workload of the thinning of laborers is reduced.

Description

technical field [0001] The design of the present invention relates to the peanut seeder technology, which is a device for adjusting the size of the hole in the peanut metering device through different stations, so as to improve the seeding accuracy of the peanut metering device, reduce the amount of seeds used and protect the seeds. Background technique [0002] Since my country's accession to the WTO, the export of peanuts in Shandong Province has increased significantly, accounting for more than 80% of the country's peanut exports, and the number of peanut planters has also increased significantly, which is of great significance to improving the production and quality of peanuts. [0003] Existing peanut seeder models are more now, but used seeder can only sow the seed of certain granularity, for the uneven number of seed sowing grains of uneven size, also waste seed. We have designed a peanut sowing device that can adjust the particle size, which can realize the adjustmen...

AI Technical Summary

Problems solved by technology

[0003] There are many types of peanut seeders that exist now, but the seeders used can only sow seeds of a certain size. For seeds with uneven particle sizes, the number of seeds is not uniform, and seeds are wasted.
