Mechanical corn miss-seeding reseeding device based on horizontal circular disc

Abstract

The invention relates to the field of agricultural mechanical equipment, and discloses a mechanical corn miss-seeding reseeding device based on a horizontal circular disc. The mechanical corn miss-seeding reseeding device is used for corn miss-seeding monitoring and automatic reseeding operation of a farmland precision seeding seed metering device. The mechanical corn miss-seeding reseeding devicecomprises a seed metering box 1, a horizontal circular disc type grading seed metering device 2, a seed scraping plate 3, a seed conveying and sand sliding hole 4, a seed conveying belt 5, a photoelectric detection valve 6, a stepping motor 7, a rolling bearing 8, a seed conveying box shell 9, a vertical seed guide pipe 10, a telescopic connecting pipe 11, an impact seed guide pipe 12 and a photoelectric sensor 13. The mechanical corn miss-seeding reseeding device based on the horizontal circular disc has the beneficial effects that the miss-seeding reseeding device can be driven immediatelywhen a miss-seeding signal is detected by the precision seed metering device in the precision seeding operation process, so that synchronous signal reseeding processing is achieved; the real-time non-reseeding condition is detected in the reseeding process, the seed conveying process of overrunning acceleration and deceleration recovery is achieved through an overrunning clutch, and compensated seeds are input into land parcel in an impact seed guide mode; and the whole device is simple in operation, intelligent, convenient and accurate in reseeding.

Description

technical field [0001] The invention belongs to the technical field of precision sowing in agricultural machinery, and is used for precision sowing and metering devices in farmland to monitor and automatically replant corn missed sowing, in particular to an automatic reseeding device for missing sowing detection. Background technique [0002] With the large-scale popularization and use of precision seeding technology, intelligent sowing monitoring tends to develop, and precision seeding missed sowing monitoring and replanting have become an inevitable trend. At present, many scholars have studied various types of missed-seeding and re-seeding devices for precision seed metering devices, but most of them are independent missed-seeding and re-seeding machines. The phenomenon of "lack of seedlings and less sowing" is not handled properly, which leads to a low rate of missed sowing and reseeding, and the effect is not obvious, and the operation must be stopped for inspection aft...

Problems solved by technology

At present, many scholars have studied various types of missed-seeding and re-seeding devices for precision seed metering devices, but most of them are independent missed-seeding and re-seeding machines. The phenomenon of "lack of seedlings and less sowing" is not handled properly, which leads to a low rate of missed sowing and reseeding, and the effect is not obvious, and the operation must be stopped for inspection after a certain distance, which wastes manpower and man-hours. , The problem of low efficiency of missed sowing and reseeding, there is an urgent need to develop high-efficiency precision seeding and missed sowing and reseeding products with great development prospects
