A Pneumatic Small-Size Seed Intelligent Plug Seedling Seeder

Abstract

The invention discloses a pneumatic seeding device for seedlings with small particle size intelligent plug trays, which includes a seeding mechanism, a missing sowing detection mechanism, a reseeding mechanism and a control module; the sowing mechanism includes a seed box, a roller, a pressure relief component and a rotating drive mechanism; The drum is rotatably connected to the frame, and the drum is provided with multiple groups of seed suction holes; the seed box is set on one side of the drum; the frame is provided with a seed cleaning sheet, and the seed cleaning sheet is arranged in front of the seed box The pressure relief assembly includes a pressure relief member and a connecting member; the missed seeding detection mechanism includes multiple sets of detection sensors, and multiple sets of detection sensors are correspondingly arranged with a plurality of seed suction holes of the same group; The rear of the drum, the re-seeding mechanism includes a plurality of suction parts, a re-seeding box, and a re-seeding feeding drive mechanism that drives a plurality of suction parts to move between the re-seeding box and the re-seeding station. The invention has a high degree of intelligence, can effectively ensure the sowing effect of one hole and one seed on the plug plate, and is beneficial to realize precise sowing.

Description

Technical field [0001] The present invention relates to a dipoprocarcut apparatus, and more particularly to a pneumatic small diameter seed smart hole breeding seeder. Background technique [0002] Acupoint seedling uses acupoints as a seedling container. When it is planted, a hole is seeded. It is a seedlings. At the same time, the quality of the seedlings is high, easy to standardize management, suitable for remote transportation and mechanized transplantation, and the replacement of the replacement is almost 100%. The development of acupoint seedlings is particularly important for vegetable production mechanization and scale. [0003] Acupoint seedlings can provide high quality seedlings for transplant, but vegetable seeds such as seeds are small diameter seeds, and the average diameter is less than 3 mm. The physical characteristics such as the geometric shape of different small particle sizes seeds are not the same, and it is the difficulty and key points developed by the re...

Problems solved by technology

However, the seeding performance of the pneumatic seed metering device in the prior art cannot meet the requirements, especially in the precision sowing of small-sized seeds with irregular shapes and relatively light weight, the seeding quality is unstable, and it is difficult to guarantee a certain The effect of seeding in one hole seriously affects the quality of seedlings, thus limiting the popularization and use of precision seeding equipment in hole trays

For example, the utility model patent "an air-suction roller-type plug seedling seedling precision seeder" with the authorized announcement number CN207040188U sucks up the seeds one by one through a plurality of seed-suction holes on the roller. Under the action of the pressure partition, the negative pressure is eliminated, and the seeds fall into the hole tray under the action of gravity, so as to complete the sowing; however, for small-sized seeds, due to the small size and quality of the seeds, it is likely to A seed suction hole appears to absorb multiple seeds, causing multiple seeds to be sown on one plug, wasting seeds, increasing costs, and even affecting normal seedling cultivation in the later stage; When the negative pressure sucks the seeds, it cannot be absorbed accurately, resulting in some or some seed suction holes having air suction, so that it is impossible to sow seeds to the plug tray, and it is impossible to achieve precise sowing
