The rear shell is fixed on an external frame; one end of the transmission shaft penetrates through the rear shell and is connected with the transmission device; the seed discharging disc is connected with the transmission shaft through a central hexagonal hole; the front shell is fixed on the rear shell; the seed protection plate is fixed on the front shell.
The operating principle of the small red bean precision seed metering device is as follows.
The operation process of the seed metering device comprises 4 stages of seed filling, seed cleaning, seed protection and seed throwing. When the seeds are filled, the power drives the seed discharging plate to rotate through the transmission shaft, the seed guide groove disturbs the seeds in the seed filling area, the mobility of the seeds is increased, the arch of the seeds is broken, and the seeds enter the seed taking device along the seed guide groove under the action of gravity, centrifugal force and interplant force; when cleaning seeds, the seed taking device carries a plurality of seeds to enter a seed cleaning area, the seeds which do not stably enter the seed taking device fall back to a seed filling area under the action of self gravity, and only 1 seed is stored in each seed taking device; when protecting seeds, the seeds are stably positioned in the seed taking device and stably move along with the seed metering disc due to the limiting effect of the seed protecting plate and the arc-shaped groove; when seeds are thrown, seeds are thrown along a seed throwing port under the combined action of the gravity and the centrifugal force of the seeds.
The utility model has the beneficial effects that: the seed sowing device is designed according to the shape and the size of the small red beans, and adopts non-contact seed cleaning, so that the breakage rate of seeds is reduced; the double rows of the seed guide grooves, the seed taking device, the arc-shaped grooves and the seed protection plates are adopted, the seed taking device is used for single row precision sowing of 1 particle during seed throwing, and the double rows of the seed taking device are used for simultaneously sowing 2 particles, so that the precision sowing of 2 particles of small red beans in each hole is realized.
