Seeding machine with functions of miss-seeding detection and reseeding

Abstract

The invention provides a seeding machine with the functions of miss-seeding detection and reseeding and used for agricultural seeding. The seeding machine comprises a seeding mechanism used for seeding, and a reseeding mechanism used for reseeding; the seeding machine further comprises a control mechanism; the seeding mechanism comprises a seed-metering device, and a detection device used for detecting whether the seed-metering device has seeds or not; a detection signal of the detecting device is fed back to the control mechanism which forms a reseeding control signal according to the detection signal; and the reseeding mechanism comprises a seed delivery device and a reseeding driving device which receives the reseeding control signal of the control mechanism to control whether the seeddelivery device delivers seeds for reseeding or not. The invention provides a seeding machine with miss-seeding detection and reseeding mechanisms. The seeding machine provided by the invention has aseeding mechanism with the function of miss-seeding detection, can detect whether the interior of a seed-metering hole has a seed or not in advance, can judge the probability of miss seeding in advance, can reseed in the premise that the probability of miss seeding occurs, and can improve seeding accuracy and seeding effect.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and relates to a seeder, in particular to a seeder with the functions of missing seeding detection and reseeding. Background technique [0002] Take the peanut seeder as an example to illustrate the structure of the existing agricultural seeding machinery. [0003] Peanut planter generally comprises the ditching mechanism that is used to dig sowing ditch, the sowing mechanism that is used to spread seed, and is used for the sowing ditch after sowing is carried out the covering soil mechanism of covering soil. The ideal sowing effect is that the sowing mechanism sows seeds evenly along the sowing ditch, but due to the structural defects of the sowing mechanism or the defects in the control of the sowing mechanical work process, the situation of missed sowing may be caused. Missed sowing means that seeds are sown at intervals, which will cause uneven sowing and affect the quality of...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that in the prior art, the sowing machine does not have the function of reseeding, or cannot perform missed sowing and synchronous reseeding, and provides a sowing machine with a missed sowing detection and reseeding mechanism. This type of sowing machine can Missed sowing detection is carried out in advance, and reseeding is carried out synchronously at the location where the missed sowing occurs, so that the accuracy of sowing can be improved and the quality of sowing can be improved
