Compensation type seed leakage detection device

Abstract

The invention discloses a compensating type seed omitted-sowing detection device which comprises a seed tank, wherein the seed tank is arranged at the upper end of a seed sowing device; a seed-draining port of the seed tank is communicated with a seed inlet of the seed sowing device; the seed-draining port of the seed sowing device is communicated with an upper end opening of a seed guide pipe; a reseeding device is arranged on one side of the seed sowing device; the seed-draining port of the reseeding device is communicated with a pipe chamber of the seed guide pipe through a reseeding pipe; a secondary seed tank is arranged at the upper end of the reseeding device; the seed-draining port of the secondary seed tank is communicated with the seed inlet of the reseeding device; an upper detector is arranged in an inner chamber of the seed guide pipe above the reseeding pipe; a lower detector is arranged in the inner chamber of the seed guide pipe under the reseeding pipe; the reseeding device comprises a fixed shell and a rotating shell; the rotating shell is sleeved in the fixed shell; a plurality of seed leaking holes are formed on a side wall of the fixed shell along the peripheral direction; a baffle mechanism and a seed feeding mechanism are arranged in the fixed shell. The compensating type seed omitted-sowing detection device is simple in structure principle, is capable of accurately judging omitted-sowing and realizing reseeding, can realize intelligent sowing operation and can promote the sowing quality.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and mainly relates to a compensation type seed leakage detection device. Background technique [0002] Agriculture is the basic industry of our country. In agricultural production, sowing is the most basic and important link. Traditional manual sowing has low efficiency, high labor intensity, and poor quality of sowing, which is not suitable for the rapid economic development of our country. [0003] With the development of agricultural mechanization, the use of seeders has become more and more extensive. Especially the single seed precision seeder. Single-seed precision sowing is suitable for crops such as corn and soybeans, which can not only save seeds, but also reduce the labor for raising seedlings in the later stage. It is inevitable that the purely mechanical seeder will miss seeding, which will affect the yield of crops. Designing a device that can detect missed sowing...
