Seed selection device and seed selection method of agricultural seeding machinery

Abstract

The invention discloses a seed selection device and a seed selection method of agricultural seeding machinery. The seed selection device comprises a material bin, a seed selection sieve, a selection plate, a switching mechanism, a seed selection unit and a controller, wherein a plurality of groups of type hole groups arranged in an array are formed in the seed selection sieve; selection holes arranged in an array are formed in the selection plate, and are arranged on the upper end surface of the seed selection sieve in an attaching way; the switching mechanism is used for driving the selectionplate to move relative to the seed selection sieve, so that different types of seed selection type hole frames can be arranged in the selection holes in a sleeving mode; the seed selection unit is used for a user to select the type of the seed to be screened at present; and the controller is connected with the switching mechanism, a translation mechanism and the selection unit. The seed selectiondevice of the agricultural seeding machinery has the advantages that the type hole groups containing different types of type holes are formed in the seed selection sieve; the different type holes arearranged by the selection hole frames arranged on the selection plate in a sleeving mode, so that the mode switching for different seeds is completed; the seed selection device can be applicable to the screening operation on various seeds; and the seed selection device and the seed selection method of agricultural seeding machinery is good in applicability, convenient to switch modes, and high inefficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a seed selection device and a seed selection method of an agricultural sowing machine. Background technique [0002] In agriculture, for some crops with high sowing requirements, it is generally necessary to select the seeds before the official sowing. The seed selection is generally to screen the size of the seeds. The purpose is to select seeds of appropriate size to ensure that after subsequent sowing, the crops The seed yield rate is higher and the growth of crops is more consistent. The current seed selection devices can only screen one type of crop, and their applicability is very limited. Generally, when different seeds need to be screened, the seed selection screen needs to be replaced, which is troublesome to operate. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present inventio...
