Tray seeder with self-cleaning suction nozzles

Abstract

The invention discloses a tray seeder with self-cleaning suction nozzles. The tray seeder comprises a frame unit, a holing system unit, a seeding system unit and a control system unit, wherein a conveyer belt transmission device pulled by a stepping motor is arranged on an upper end face of the frame unit; the holing system unit is provided with a holing supporting beam which stretches across frame main girders; a group of holing heads are arranged on each row of holing beam; a seeding beam connecting rod is fixed between a pair of swing arms of a swing mechanism of the seeding system unit; at least one row of seeding beams are fixed on the seeding beam connecting rod; a row of self-cleaning suction nozzles are arranged on the lower side of each row of seeding beam; a vibrating seed tray for accommodating seeds is arranged below the self-cleaning suction nozzles; the control system unit comprises a control box, a group of air-operated solenoid valve components, a group of photoelectric sensors, photoelectric sensor reflectors matched with the photoelectric sensors, and a sensor contact block fixed on a swing shaft of the seeding system unit; and the control system unit controls the start / stop of electric parts of each unit. By the tray seeder, the seeding efficiency and seeding precision can be improved, and high quality and high yield of seedlings are guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of agricultural engineering and relates to a tray seeder with a self-cleaning suction nozzle. Background technique

[0002] Seedling production is a time-sensitive and highly technical job, and whether the sowing can be completed smoothly as scheduled and the quality of the sowing will directly affect the implementation of the follow-up seedling production plan and the quality of the product. The research on seeding in protected cultivation production in foreign countries is relatively early and has a high level, but foreign plug seeder products are expensive, while domestic research and development and application of this aspect lag far behind foreign countries, making us long-term in the primitive state of sowing. stage, not only labor-intensive, but also difficult to control the quality of sowing. Sowing is the core link in the production of seedlings in plug trays. However, the key technology level of s...
