Embodiment Construction

[0013] The optimal embodiment of the present invention is as figure 1 Shown: the single seed planter includes a frame (1), fan (2), landing wheels (7), several groups of single seed metering devices (3), columbine legs (4), soil covering device (5) and pressing wheels (6), wherein the seed bin bottom plate (9) for the single-grain metering device (3) is an openable and closable movable baffle driven by an electric device, and the opening and closing mode can be a translational type or a spiral. The upper part of the seeder is a seed disc platform (13). The seed tray (14) is made up of several seed boxes (15), and each seed box (15) has an independent cover (32). The seed disc (14) is locked on the push-pull track (19) in the seed disc platform (13), and is put into or taken out of the seed disc platform (13) along with the push-pull track (19). A seed tray (14) corresponds to a seed inlet (11), and the seed inlet (11) is below the seed tray (14). The seed disc (14) can mov...

Abstract

The utility model relates to an automatic seed changing and supplying device for a single seed planter, which belongs to the technical field of agricultural machinery. There are many breeding materials in crop breeding experiments, which need to be frequently replaced when sowing. The present invention aims to solve the problem of frequent replacement. The automatic seed changing and supplying device of the present invention comprises: the bottom plate of the seed chamber for supplying seeds to the single seed metering device is a movable baffle that can be opened and closed, the seed chamber is upwardly connected with the seed inlet through the seed pipe, Above is the seed tray. The seed tray consists of several seed boxes, each with its own lid. The seed disk is locked on the track of the seed disk platform, and can move back and forth, left and right under the drive of the motor. There is a seed box cover switch device next to the seed inlet. Every time the seeder advances for a certain distance, the travel recorder sends a signal to the controller, and the controller controls the bottom plate of the seed bin, the switch device of the seed box cover and the seed tray to move once to complete a change and supply operation, realizing automatic change and supply, improving Sowing efficiency.

Description

technical field [0001] The invention relates to a crop seeder, in particular to an automatic seed changing and seed supply device for a single seed seeder, and belongs to the technical field of agricultural machinery. Background technique [0002] There are thousands or even tens of thousands of breeding materials (seeds) that crop breeders need to sow every year. Each material is generally only a few meters long and requires single seed sowing. The traditional seeder cannot meet its sowing requirements, and now most breeding units in our country still have to adopt the artificial on-demand sowing method. The efficiency of artificial on-demand seeding is low and the seeding quality is not guaranteed, which has a negative impact on breeding experiments. Austria has produced a "Plotspider", which adopts the principle of air-suction seeding to achieve single-grain sowing. There are devices for changing and supplying seeds, but manual operation is still required. All need shut...
