Vibrational flow type seeder

Abstract

The invention provides a vibration flow-type sowing machine which comprises a seed tank, a discharge plate, a seed tank vibrator, a screening plate vibrator, a screening plate, a V-shaped fluted plate, an air compressor and a machine frame. The seed tank vibrator is arranged on the seed tank. Seed guide plates are installed inside the seed tank and arranged in stepped, multi-layered and cross configuration, and the seed tank is arranged on the machine frame via a seed tank supporter. The screening plate is connected with the V-shaped fluted plate via a screening controller plate and a connecting bolt. The V-shaped fluted plate is arranged on a vibrating plate spring. The discharge plate is rested against the top surface of the screening plate. The screening plate vibrator is arranged on the vibrating plate spring. The screening plate vibrator and the seed tank vibrator are respectively connected with the air compressor via air pipes and pressure control valves. The sowing machine realizes the screening and decontamination of seeds without damaging seed buds, and solves the problem that the sowing accuracy is affected by the blockage of crushed seeds and seed buds or small impurities in the V-shaped fluted plate during the seed transport process. The sowing machine is particularly suitable for the high-precision seed raising and sowing of super-grade rice seeds and is also suitable for the precision sowing of common rice, wheat, flowers, vegetables and germinated seeds.

Description

Technical field: [0001] The invention relates to a flow type seeder, in particular to a precision seeder for raising seedlings. Background technique: [0002] Precision seeding is an advanced planting method, which has significant advantages such as saving seeds, saving seedling labor, increasing production, and improving crop quality. At present, it has become the main way of field planting of various crops in various countries in the world. With the continuous development of modern agricultural technology, especially the continuous maturity of seed engineering technology, the planting requirements and growth environment of crops in the field have undergone tremendous changes. Now most of the field crop planting methods have changed from traditional drill sowing, hole sowing or semi-precision seeding. Sowing, gradually developing to the planting method of precision sowing. At present, the crops for precise sowing include: corn, soybean, sugar beet, sunflower, wheat, rice ...

Problems solved by technology

Domestic Shandong University of Technology, Guangxi University, and South China Agricultural University have successively used vibrating seed metering devices to sow rice, but they all use grooved wheel type, spoon wheel type and other seed supply devices to separate seeds, which causes high damage to the seeds, and does not carry out any inspection on the seeds. Impurity removal and screening, many impurities, poor sowing performance
