Embodiment Construction

[0029] Such as figure 1 , figure 2 As shown, the present invention includes one or more independently operating seed meters mounted on the sowing unit of the planter. The seed metering device includes an outer casing 1 installed on the sowing unit of the seeder and having an opening at the bottom, a control system 2 installed on the outer casing 1, a detection unit 11 connected to the control system 2, and a control system controlled by the control system. 2. Alarm unit for control 3. Horizontally installed at the bottom opening of the outer casing 1, on which a circle of multiple seed nests 10 are evenly distributed along the circumferential direction and can continuously rotate on the horizontal plane. 4. Located on the seeding plate The seed box 6 above one side is installed inside the seed box 6 and continuously stirs the seeds contained in the seed box 6 to ensure that the seeds continuously fall to the agitator 7 of the seed tray 4, and the seed tray 4 and The drive m...

Abstract

The invention discloses a seeding unit used in an air-jet type high speed and no-tillage precision seeder, comprising one or a plurality of seed metering devices which work independently and are arranged at the seeding unit of a seeder. The device comprises an outer shell, a control system arranged on the outer shell, a detecting unit connected with the control system, an alert unit controlled by the control system, a seed metering disc which is horizontally arranged at the bottom of the outer shell, is distributed with a ring of seed pits uniformly along the circumferential direction of the upper edge and can rotate continuously in the horizontal plane, a seed hopper, a mixer arranged inside the seed hopper, a driving mechanism which drives the seed metering disc and the mixer and is controlled by the control system, and a seed-clearing brush. The seeding unit has the advantages of simple structure, compact installation, reasonable design and convenient operation, and 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, and in particular relates to a seed metering device for an air-spray type high-speed no-tillage precision seeder. 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, because of the less operations on the soil, it has the advantages of not only reducing the damage to the soil plow layer and the evaporation of soil water, but also shortening the 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 ...
