This utility model discloses a portable leek harvesting basket, including a harvesting basket body and a collection basket. The upper perimeter of the harvesting basket body contacts the lower perimeter of the collection basket. A fixing block is installed on the right side of the lower end of the harvesting basket body. Telescopic automatic adjustment rods are installed on the front and rear sides of the upper end of the fixing block. The beneficial effects of this utility model are: the combination design of the telescopic automatic adjustment rod and the universal wheels allows for flexible height adjustment according to user needs and easy movement, reducing the intensity of manual handling. It is especially suitable for harvesting operations in large-scale leek planting bases, greatly improving transportation efficiency. The precise fitting structure of the positioning groove and the positioning base, combined with the fixed connection method of the mounting block, ensures that the harvesting basket body, collection basket, universal wheels, and other components are firmly connected, without loosening or shaking during movement and loading, effectively preventing leek spillage and loss. The protective baffle forms a lateral barrier to prevent leeks from falling due to collision during transportation.
