Abstract

The invention discloses a single cylinder-driven plugging-clamping-type aperture disk seedling transplanting paw. The driving cylinder is mounted below an upper plate of a support; a cylinder rod is fixedly connected with one end of a screw thread push rod; a seedling needle installing plate is fixed to the screw thread push rod; four seedling needle fastening sliding parts are respectively fixed at the four side surfaces of the seedling needle installing plate; an intermediate pressing plate is separated from a needle pipe installing plate by a spring to form a sliding pair; one end of each of four needle pipe fastening rotating parts is mounted in a respective groove of the intermediate pressing plate to form a sliding pair with a cylindrical pin; the other end is mounted in a respective groove of the needle pipe installing plate to form a rotating pair; four seedling withdrawing needle pipes respectively pass through their respective needle pipe fastening rotating parts and are fixedly connected; the other end of each of four seedling picking needles passes through the respective seedling withdrawing needle pipe to form a sliding pair; the needle pipe installing plate is mounted on a lower plate of the support. The paw of the invention completes two actions of inserting and clamping within one extending stroke of the cylinder; the depth and the angle of the seedling picking needles inserting into pot seedlings can be adjusted conveniently; and the paw has strong adaptability to various crop kinds and various aperture disk specifications.

Description

technical field

[0001] The invention relates to agricultural machinery, in particular to a single-cylinder-driven plug-and-pull-clamping gripper for transplanting seedlings in plug trays. Background technique

[0002] Plug seedling technology has been widely used in the market because of its many advantages such as high germination rate, neat seedlings, less pests and diseases, short growth cycle, no seasonal restrictions, and convenient mechanized operations. In the process of growing seedlings in plug trays, it is necessary to transplant the pot seedlings that are not growing well or the hole holes that have not been sown or germinated. When the pot seedlings grow to a certain stage, they need to be transplanted thinly. The traditional manual transplanting operation is labor-intensive and the work efficiency is not high. In contrast, mechanized transplanting equipment can not only reduce the labor intensity of workers, greatly improve work efficiency, but also ensure the ...
