Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a spraying device for seedling cultivation. Background Art

[0002] Seedlings usually refer to seeds that have germinated, generally grown to 2 pairs of true leaves, and then to young plants that are suitable for transplanting to other environments. Seedlings can be divided into many types, including flower seedlings, seedlings, vegetable seedlings, aquatic seedlings, and medicinal seedlings. Seedling cultivation is a complex process involving many aspects, including soil management, seedling breeding and grafting technology, and pest and disease control.

[0003] A spraying device for a Phalaenopsis orchid planting and cultivation base with announcement number CN 212937187 U is provided. By setting a lifting mechanism, the equipment can spray Phalaenopsis orchids at different heights. At the same time, by setting a swing mechanism, the nozzle can swing back and forth, so that the equipment can evenly spray the Phalaenopsis orchids within the range, thereby greatly increasing the spraying effect on the Phalaenopsis orchids and ensuring the normal growth of the Phalaenopsis orchids.

[0004] The spray device for a Phalaenopsis planting and cultivation flower-growing base is provided with a swing mechanism so that the spray head can swing back and forth, so that the equipment can evenly spray the Phalaenopsis within the range.

When the spray head rotates, it cannot drive the transmission frame to rotate, so that the rotating frame can reduce the rotation range of the spray head, and the water sprayed by the spray head is blocked by the transmission frame. Therefore, improvement is needed. Utility Model Content
