Seedling pushing and inclined cutting type pot clamping and seedling picking end actuating device and method

Abstract

The invention belongs to the field of agricultural machinery and provides a seedling pushing and inclined cutting type pot clamping and seedling picking end actuating device and method. The seedling pushing and inclined cutting type pot clamping and seedling picking end actuating device comprises a seedling pushing and inclined cutting unit and a parallel opening and closing unit, wherein the seedling pushing and inclined cutting unit is obliquely fastened on a bracket; the parallel opening and closing unit is located just below the seedling pushing and inclined cutting unit and is straightlyfastened on the bracket; when seedlings are picked, seedling plants are firstly bent by utilizing a seedling pushing plate of the seedling pushing and inclined cutting unit and a working space of clamping needles is formed; then the clamping needles are used for obliquely inserting and clamping a pot body along the diagonal direction of holes; under the driving a seedling picking mechanism, seedlings are taken out from the holes; when the seedlings are put, the clamping needles are firstly loosened and then the clamping needles are retracted back, so that the pot body of the seedlings are released from a clamping effect; the seedlings and the pot body in which the seedlings grow fall into a planting system through self-weight. The seedling pushing and inclined cutting type pot clamping andseedling picking end actuating device is simple in structure and can be used for effectively preventing the seedlings from being injured when the seedlings are clamped by the needles; two pairs of the clamping needles are obliquely inserted into the pot body along the gradient angle position of the edges of the holes so that the maximum clamping depth can be ensured; the seedling picking qualityis ensured relatively well and the seedling pushing and inclined cutting type pot clamping and seedling picking end actuating device can be used for the field of mechanical transplanting of plug seedlings.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to an end effector for pushing seedlings and inserting them obliquely into a clamping bowl for picking seedlings and a method thereof. Background technique [0002] The seedling-taking end effector is a device that liberates manual labor. Driven by the seedling-taking mechanism, the seedlings are picked out from the growth hole and released to the corresponding planting system. Foreign automatic transplanters for plug seedlings widely use flexible claws to take seedlings, such as the Dutch Pic-O-Mat PC series automatic transfer machine, the Italian Transplanter RW series transplanter, etc., which perform well in terms of seedling picking speed and seedling quality . [0003] Scholars in my country have designed end effectors according to the needs of picking seedlings from pots, such as pneumatic seedling claws for pot seedling transplanting machines, application n...

AI Technical Summary

Problems solved by technology

These similar seedling picking end effectors only consider the needs of picking seedlings from the pot, and do not consider the characteristics of the seedlings, especially the seedlings with large stems and leaves, and the height of the plants is large. The direct clamping method will inevitably cause damage to the seedlings. In severe cases, the stems of the seedlings will be pinched off, so it is meaningless to take seedlings for transplanting
