The invention relates to the technical field of peanut sowing machinery, in particular to a multi-seed pre-seed-filling type single peanut seed sowing device which comprises a machine shell, seed sowing discs and an arc-shaped seed protection plate, a seed inlet and a seed feeding opening are formed in one side of the machine shell, a seed throwing opening and a seed sowing pipe are arranged below the machine shell, the seed sowing discs are divided into the left seed sowing disc and the right seed sowing disc, and the arc-shaped seed protection plate is arranged on the left seed sowing disc and the right seed sowing disc. After the seed-metering plate is spliced, a V-shaped structure is formed at the large-diameter part in the middle of the seed-metering plate. Two or more seeds can be filled into the seed-metering disc in the seed filling stage through the seed-metering disc designed in a V-shaped structure and the inclined long-groove-shaped holes, the seed filling performance of the seed-metering device is improved, it is ensured that the number of the seeds can be accurately controlled in each hole through the design of the inclined long-groove-shaped holes arranged in a staggered mode, single-seed sowing is achieved, and the seed-metering efficiency is improved. And moreover, the number of the shaped holes with the elongated slot-shaped structures can be increased under the condition that the diameters of the seed-metering plates are the same, so that the operation speed of the seeder is increased, and the working efficiency is improved.

The present application relates to peanut seeding mechanical technology field, specifically to multi-grain pre-charging seed type peanut single-seed sowing seed metering device, including the casing, the seed plate and the arc seed protection plate, one side of the casing is provided with the seed inlet and the seed inlet, the seed inlet and the seed tube are provided below the casing, the seed plate is divided into left seed plate and right seed plate, and both can be spliced into an integral, the seed plate is spliced after the middle large diameter forms V type structure. The seed plate of V type structure design and the inclined long groove type hole make the seed plate can be filled with two or more seeds in the filling stage, improve the filling performance of the seed metering device, through the design of the inclined long groove shape structure of the staggered arrangement, ensure that the number of seeds in each type hole can be accurately controlled, realize single-seed sowing, thereby improve the seeding accuracy, and the long groove shape structure type hole can allow to increase the number of type holes under the condition of the same diameter of the seed plate, thereby improve the working speed of the seeding machine, improve work efficiency.
