AI Technical Summary

Technical Problem

Existing tobacco seedling trays tend to have the seedling substrate stick to the inner wall of the seedling hole when seedling cultivation is completed, and they are prone to breakage and scattering when removed. Furthermore, they have a complex structure, high cost, and are prone to malfunction.

Method used

An elastic mesh tube is placed inside the seedling hole. The mesh tube is closed end to end under the constraint of the inner wall of the seedling hole. When it is removed, it expands radially under the action of elasticity to form an arc-shaped tube, which isolates the substrate from the inner wall of the seedling hole, avoids adhesion and keeps the substrate intact.

Benefits of technology

It achieves easy separation of the substrate from the inner wall of the seedling hole, preventing the substrate from scattering. It has a simple structure, low cost, and is easy to operate, making it suitable for large-scale application.

Abstract

本实用新型涉及一种烟草育苗盘，有效的解决了育苗基质与育苗穴粘连、取出时基质破碎散落的问题；解决的技术方案包括育苗盘主体，育苗盘主体上均布有若干育苗穴，每个育苗穴内装有一个网筒，网筒是由一个具有弹性的网片卷曲而成上下开口的筒状，网筒装在育苗穴内时，在育苗穴内壁的限位作用下，网片的首尾对合，网筒拿出育苗穴后，在弹性作用下，会径向扩张而首尾分离，形成一个具有轴向开口的弧形筒状；本实用新型通过网筒隔离和包裹基质，能够大大减轻基质和育苗穴内壁的粘连，能够避免基质散落，且结构简单，成本低廉，能够大规模应用。

Claims

1. A tobacco seedling raising tray comprising a seedling raising tray main body having a plurality of seedling raising holes (2) uniformly distributed thereon, characterized in that, Each seedling hole (2) contains a net tube (3). The net tube (3) is a cylindrical shape with an opening at the top and bottom formed by rolling up an elastic net sheet. When the net tube (3) is placed in the seedling hole (2), the ends of the net sheet are aligned under the limiting action of the inner wall of the seedling hole (2). After the net tube (3) is taken out of the seedling hole (2), it will expand radially and separate from the end under the elastic action, forming an arc-shaped cylindrical shape with an axial opening.

2. A tobacco seedling tray according to claim 1, wherein Both the seedling holes (2) and the net tubes (3) are cone-shaped with a small lower end.

3. A tobacco seedling tray according to claim 2, wherein The angle between the conical generatrix of the seedling hole (2) and the axis of the net tube (3) is no greater than 5 degrees.

4. A tobacco seedling tray according to claim 1 or 2 or 3, wherein, An elastic ring (4) is threaded through both the upper and lower ends of the net cylinder (3).

5. A tobacco seedling tray according to claim 1, wherein The bottom of the seedling hole (2) has a water-permeable hole (5).
