Bowl sports seedling precision seeding line

Abstract

The invention discloses a precision seeding assembly line for pot seedling. The precision seeding assembly line comprises a frame and a seedling plate conveyer belt, wherein the seedling plate conveyer belt is arranged on the frame; an automatic seedling plate feeding device, a seedbed soil pressing device, a precision seeding device and an earthing device are orderly fixed on the frame above the seedling plate conveyer belt; seedling plates with holes are regularly arranged above the automatic seedling plate feeding device and orderly conveyed to the subsequent devices by virtue of the seedling plate conveyer belt; finally, automatic line production of seedling plate conveying, substratum filling, punching, precision seeding, panning and earthing is finally achieved. By adopting the precision seeding assembly line, the germination rate and the seedling rate of sprout cultivation are further improved, and the root of a rice seedling is increased, so that the survival rate and the mechanical operation level after seedling planting are improved, the working hours are saved, the operation cost is reduced, and the work efficiency of seedling cultivation is effectively improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an assembly line for precise seeding of pot seedlings. Background technique [0002] The automatic seeding assembly line is one of the most basic production tools in modern agricultural production. Its main sowing steps include mixing soil materials, feeding trays, loading soil, pressing holes, sowing, covering soil, sprinkling and stacking trays. The pressure holes of the automatic seeding assembly line in the prior art adopt the usual cylinder to drive the pressure hole supports to press down row by row. The disadvantages are complex structure, troublesome installation, high cost and low pressure hole efficiency. The existing sowing adopts a pneumatic sowing drum, and the positive and negative pressure switching in the ventilation device is completed by a solenoid valve, and is set on the shaft through an air groove. This structure requires high processing accura...

AI Technical Summary

Problems solved by technology

The pressure holes of the automatic seeding assembly line in the prior art adopt the usual cylinder to drive the pressure hole support to press down one by one row. The disadvantages are complex structure, troublesome installation, high cost and low pressure hole efficiency.

The existing sowing adopts a pneumatic sowing drum, and the positive and negative pressure switching in the ventilation device is completed by a solenoid valve, and is set on the shaft through an air groove. This structure requires high processing accuracy and makes processing difficult. ,high cost

The existing soil covering adopts the funnel type. When the seedling tray with seeds is transported to the bottom of the soil covering box by the conveying mechanism, the gate plate on the bottom surface of the soil covering box is opened, and the soil material falls. The soil material on the seedling tray is thick or thin, which affects seed cultivation
