Shear-fork type variable-pitch mechanical arm

Abstract

The invention relates to a shear-fork type variable-pitch mechanical arm, and aims to provide a mechanical arm which can be used for transferring a seedling cup from a cell pan on which cell holes are densely distributed to a planting plate on which cell holes are sparsely distributed to prepare for subsequent full-automatic transplanting operation so as to improve the working efficiency of full-automatic transplanting operation. The mechanical arm has the characteristics of simple and practical structure, and is convenient and easy to manufacture. By adopting the technical scheme, the shear-fork type variable-pitch mechanical arm is characterized by comprising a plurality of clamping carriers which are fixed on a rack and are used for clamping seedling cups, a steel wire tightening mechanism used for applying clamping force to the clamping carriers, and a shearing mechanism which is used for adjusting the distance between the clamping carriers by means of opposite driving of two cylinders.

Description

technical field [0001] The invention relates to the technical field of leaf vegetable transplanting machinery, in particular to a scissor-type variable-distance pot-moving manipulator capable of transferring seedling cups containing seedlings from small-spaced hole trays to large-spaced planting plates. Background technique [0002] With the continuous improvement of agricultural production automation technology, the people's demand for green leafy vegetables is growing rapidly; the current leafy vegetable seedlings have gradually transitioned from manual transplanting to mechanical transplanting (because of the high cost and slow speed of manual transplanting, it is already very slow). Difficult to keep up with the pace of modernization); but the mechanized transplanting operation needs to transfer the seedling cup 6 from the densely arranged hole tray 10 of the hole 10-1 to the sparsely arranged hole (the spacing between the holes is relatively large) The planting board 20...

[0002] With the continuous improvement of agricultural production automation technology, the people's demand for green leafy vegetables is growing rapidly; the current leafy vegetable seedlings have gradually transitioned from manual transplanting to mechanical transplanting (because of the high cost and slow speed of manual transplanting, it is already very slow). Difficult to keep up with the pace of modernization); but the mechanized transplanting operation needs to transfer the seedling cup 6 from the densely arranged hole tray 10 of the hole 10-1 to the sparsely arranged hole (the spacing between the holes is relatively large) The planting board 20 ( Figure 7 shown), this part of the operation still needs to be done manually, and an auxiliary device is urgently needed to replace it.
