Abstract

The invention discloses an intelligent dual-seed-filling hole roller rice precision sowing device. The intelligent dual-seed-filling hole roller rice precision sowing device is composed of a seed box,a dual-seed-filling seed supply mechanism, a hole roller, a seed-filling quality monitoring feedback system, a seed clearing wheel, a synchronous seed protection rubber belt, a steel wire seed pushing mechanism, an electromagnetic direct vibrator and a mandrel. The dual-seed-filling seed supply mechanism is composed of a first seed-filling mechanism body formed by stacked seed guiding plates anda second seed-filling mechanism body formed by vibration-flow V-shaped groove plates. The seed-filling quality monitoring feedback system is composed of detection sensors, a mounting frame and a control module, wherein the detection sensors are installed in the form of correlation, the control module is connected with the electromagnetic direct vibrator, and by detecting hole signals, startup andshutdown of the electromagnetic direct vibrator are controlled; the steel wire seed pushing mechanism is located in the hole roller, the sowing process sequentially comprises the procedures of primaryfilling, monitoring feedback, secondary supplement, seed clearing, seed protection and seed putting. The intelligent dual-seed-filling hole roller rice precision sowing device effectively solves theproblems that when a traditional roller seeder works, rice seeds have poor mobility in seed filling chambers, the seed filling reliability is low, and holes are easily blocked. Therefore, the intelligent dual-seed-filling hole roller rice precision sowing device has practical value.

Description

technical field [0001] The invention relates to the technical field of rice seedling tray seedling raising, in particular to an intelligent rice precision seeding device and a seeding method of a roller with double-filled seed holes. Background technique [0002] The existing rice mechanized seedling raising and transplanting technology and corresponding equipment are developed on the basis of conventional japonica rice planting. However, there are still many problems in the mechanized planting technology suitable for hybrid rice production. In the production process of the prior art, the planting of hybrid rice is still mainly based on artificial planting, but the planting of hybrid rice emphasizes less planting and sparse planting, and the use of strong tillering ability to increase yield. Therefore, hybrid rice seedling raising and sowing technology requires the use of low-volume precision seeding technology , usually 1 to 3 grains / hole or grid (1 to 2 plants / hole when pl...
