Automatic picking and placing device for plug seedling transplanting

Abstract

The invention relates to a device for automatically transplanting seedlings in plug trays, which mainly consists of a cam feeding mechanism, a conical slider, four mechanical fingers, a mechanical finger limit block 9, a clamping needle 14, a traction brake line 11, a brake Composed of wire pulling device, spring 12, support rod 19, frame, etc.; the four mechanical fingers can be opened around the joints under the push of the cam feed mechanism, and kneaded under the action of the spring force. Each mechanical finger is equipped with a retractable Insert and extend the clamping needles, extend the mechanical fingers through the four clamping needles, insert them into the seedling pot body of the plug and pinch the seedlings tightly, and retract the mechanical fingers through the four clamping needles to leave the seedling pot body of the plug to loosen the seedlings. The feature of the present invention is that the opening and closing of four mechanical fingers and the expansion and contraction of four clamping needles are realized completely by means of mechanical movement. The structure is simple, the flexibility is good, the success rate of seedling picking is improved, and the injury to seedlings is reduced. It can be applied to plug seedling transplanting field.

Description

technical field [0001] The invention relates to the field of automatic transplanting machinery for plug seedlings, in particular to a device for picking and placing seedlings for automatic transplanting of plug seedlings. Background technique [0002] Industrial plug seedling cultivation is the pioneer of modern agriculture and industrial agriculture, and has become the leader of modern vegetable and flower industry. The supporting seedling cultivation and transplanting technology and equipment can not meet the great development of seedling industrialization. Although my country has developed various types of vegetable seedling transplanting machines such as clamp type, chain clamp type, flexible disc type, hanging cup type, and seedling guide tube type, these transplanting machines remain at the semi-mechanical level. , needs to be equipped with considerable manpower to manually take seedlings, throw seedlings and other operations, but it is labor-saving but not labor-saving...

AI Technical Summary

Problems solved by technology

In addition, the medium of plug seedlings in my country is mainly herbaceous peat, and then mixed with auxiliary materials such as vermiculite and perlite. The pots of the plugs cultivated have poor flexibility and are easily broken when clamped by two needles.
