Lettuce combine harvester

Abstract

The invention provides a lettuce combine harvester which comprises a harvesting device, a conveying belt system, a rough leaf stripping device and a crawler-type chassis, the leaf stripping device is installed on the crawler-type chassis, and the harvesting device is located on the front portion of the crawler-type chassis; the leaf stripping device comprises a rough leaf stripping device; the rough leaf stripping device comprises fixing rods, pressing rods and an air blowing device, the multiple fixing rods are arranged on the two sides of the conveying belt system, the crank sliding block mechanisms are installed at the two ends of each fixing rod respectively, the pressing rods are installed between sliding blocks of the crank sliding block mechanisms at any ends of the adjacent fixing rods, and through the reciprocating linear motion of the two sliding blocks on the fixing rods, lettuce leaves are clamped and torn; and the air blowing device is located near the rough leaf stripping device and used for blowing the lettuce leaves in the conveying belt system open through airflow, and the rough leaf stripping device can conveniently clamp the lettuce leaves. According to the lettuce combine harvester, lettuce leaf stripping and harvesting are efficient and automatic in the whole process, and the lettuce harvesting speed and quality are improved.

Description

technical field [0001] The invention relates to the field of agricultural harvesting equipment, in particular to a lettuce combine harvester. Background technique [0002] Lettuce is an annual or biennial herb with a height of 25-100 cm. The above-ground stems are edible. The stem skin is white-green. The flesh of the stem is crisp and tender. The young stems are emerald green and turn white-green when mature. It has extremely high medicinal and dietary value . Lettuce is cultivated all over China, and some are wild. Summer lettuce harvest is also the fastest period for bolting. If it is not harvested in time, the quality of the plant will become hard or even hollow after bolting, which will greatly affect the quality of lettuce. Yield and quality, but most of the lettuce grown at present is manually harvested or harvested by small simple carts, and the harvesting process is separated from the peeling process, which greatly prolongs the harvesting time of lettuce and greatl...

AI Technical Summary

Problems solved by technology

[0004] The existing technology realizes the functional requirements of lettuce planting and harvesting under limited conditions, or provides a method for removing the skin and leaves of columnar crops, but it is not suitable for the harvesting conditions of outdoor medium-scale lettuce planting, and outdoor planting may face water resources. The problem of inconvenient retrieval, the problem that small-scale hand-push machines cannot meet the needs of large-scale lettuce planting, and the problem that the leaf peeling process should be completed in a shorter time while maintaining quality
