Description

Plant seedling hydroponic device

technical field

The utility model relates to a plant hydroponic device.

Background technique

Hydroponics, also known as solution culture, refers to the method of cultivating plants with an aqueous solution containing a certain amount of nutrients needed for plant growth. Compared with the traditional soil seedling cultivation method, hydroponic seedling cultivation has the characteristics of not being restricted by region, time and space, and easy to control the growth environment. It has now developed into a mature plant cultivation method and is widely used in gardening and agricultural production.

The existing plant seedling hydroponic box mainly includes a box body and a cover plate. The box body is equipped with a culture solution. The roots of the plant seedlings protrude into the box, and the seedlings of the seedlings are exposed outside the cover plate. Since the stems of the seedlings are relatively slender and fragile, this kind of hydroponic tank structure lacks support and fixation for the plant seedlings, and the plants The roots are in a liquid environment, which can easily lead to bending and breaking of long-stem plant seedlings, affecting the normal growth of plant seedlings. Simultaneously, the round holes on the cover plate of this kind of hydroponic box are all on the same level, and the depth of immersion of the roots of the seedlings in the nutrient solution cannot be adjusted, and it is not suitable for the water cultivation of plant seedlings in different growth states.

Utility model content

The utility model solves the problems that the existing seedling hydroponic devices lack support and fixation for the seedlings and cannot adjust the depth of the seedling roots immersed in the nutrient solution, and provides a plant seedling hydroponic device.

The hydroponic device for plant seedlings of the utility model comprises a hydroponic box, a cover plate and a casing. The hydroponic box is a rectangular box, and two opposite walls of the hydroponic box are respectively provided with a liquid inlet and a liquid outlet. The cover plate is placed on the upper edge of the hydroponic box, and there are a plurality of circular holes on the cover plate. Two positioning pins are arranged on the hole wall of each circular hole. The positioning pin holes where the positioning pins are located are provided with The spring, wherein the casing is composed of a left half casing and a right half casing hinged, the casing is inserted into a circular hole, and a plurality of positioning holes are respectively opened on both sides of the casing along the axial direction of the casing, and the positioning holes are connected with the circular hole. The positioning pins in the holes are matched, and a plurality of strip-shaped holes are evenly distributed on the surface of the casing.

Insert the casing in the plant seedling hydroponic device of the present invention into the round hole on the cover plate, select the appropriate height of the casing exposed above the cover plate according to the length of the stem of the plant seedlings to be cultivated, and pass through the two sides of the casing. The positioning hole on the side cooperates with the positioning pin in the round hole for positioning, and the sleeve is used to effectively support and fix the stalk of the plant seedling. At the same time, since the plant seedlings are hung on the casing, by adjusting the position of the casing up and down, the depth of the roots of the plant seedlings immersed in the nutrient solution can also be controlled at the same time, so that different types of seedlings or plant seedlings in different growth states can be watered at the same time. It is possible to cultivate seedlings.

Detailed ways

Specific Embodiment 1: The hydroponic device for plant seedlings in this embodiment includes a hydroponic box 1, a cover plate 2 and a casing 3. The hydroponic box 1 is a rectangular box, and the two opposite walls of the hydroponic box 1 are respectively There is a liquid inlet and a liquid outlet, and the cover plate 2 is placed on the upper edge of the hydroponic box 1. There are a plurality of round holes 2-1 on the cover plate 2, and the holes in each round hole 2-1 Two positioning pins 2-2 are arranged on the wall, and a spring 2-3 is arranged in the positioning pin hole where the positioning pin 2-2 is located, wherein the casing 3 is composed of a left half casing 3-1 and a right half casing 3-2. Hinged composition, the casing 3 is inserted in the round hole 2-1, and a plurality of positioning holes 4 are respectively opened on both sides of the casing 3 along the axial direction of the casing 3, and the positioning holes 4 and the positioning in the round hole 2-1 The pins 2-2 are matched, and a plurality of strip-shaped holes 5 are evenly distributed on the surface of the sleeve 3 .

In this embodiment, the positioning pin in the round hole of the cover plate points to the center of the round hole along the radial direction of the round hole.

This embodiment can not only support the plant seedlings through the casing exposed on the cover plate, but also adjust the length of the casing under the cover plate to restrict the growth of the roots of the plant seedlings, avoiding the mutual entanglement of the roots of adjacent seedlings, and the nutrient solution through the casing The strip holes on the tube flow into the casing, which does not affect the absorption of the nutrient solution by the roots of the seedlings.

Embodiment 2: This embodiment differs from Embodiment 1 in that the upper port of the casing 3 is a closing structure.

In this embodiment, the closing structure of the casing facilitates the fixing of the plant seedlings.

Specific embodiment three: this embodiment is different from specific embodiment one or two in that an end cap 3-3 is also provided on the lower port of the casing 3, and a plurality of strip-shaped holes 5 are opened on the end cap 3-3 .

Embodiment 4: This embodiment differs from Embodiments 1 to 3 in that a plurality of round holes 2-1 are opened on the cover plate 2, and the round holes 2-1 are arranged in a rectangular array.

Embodiment: The hydroponic device for plant seedlings in this embodiment includes a hydroponic box 1, a cover plate 2 and a casing 3.
