Abstract

The invention discloses a seed metering and sprinkling device used in an air-jet type high-speed and no-tillage precision seeder, comprising one or a plurality of seed metering and sprinkling devices which work independently and are arranged at the seeding unit of the seeder. The seed metering and sprinkling device comprises an outer shell which is arranged at the seeding unit of the seeder and is provided with an opening at the bottom, a seed metering device and a seed sprinkling device which are arranged inside the outer shell, a control system which is arranged at the outer shell and respectively controls the seed metering device and the seed sprinkling device, a detecting unit connected with the control system and an alert unit controlled by the control system. The seed metering and sprinkling device has the advantages of simple structure, compact installation of seed metering and sprinkling devices, reasonable design and convenient use and operation, can effectively solve the practical problems of complicated structure of the seeder, low seed metering speed and the like in the existing suction-type or air-jet type seed metering devices.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to an air-spray type high-speed no-tillage precision seeder for metering / spraying seeds. Background technique [0002] At present, with the intensification of the international food crisis and the destruction of the soil environment, countries around the world have taken corresponding measures to increase food production and gradually reduce the degree of damage to the environment. For no-tillage seeding, due to the less number of operations on the soil, it has the advantages of reducing damage to the soil plow layer and evaporation of soil moisture, shortening operation time, and reducing agricultural input. The no-tillage seeder is a new type of machine tool that appeared in the 1990s to adapt to the new planting technology of the above-mentioned no-tillage sowing. It is mainly used for direct sowing without plowing or less plowing of the soil after wheat harvest. ...
