CULTIVATION ASSEMBLY TECHNICAL FIELD

The present invention relates to a container for cultivating insects, small

animals, or plants, and more particularly to a cultivation assembly that can be

flexibly assembled according to requirements of usage and can save labor in

assembling multiple cultivation assemblies side by side.

BACKGROUND

A cultivation box is a container for breeding insects, small animals, or

plants. However, breeding fishes, shrimps, or plants requires a large area of land

for building a culture pond or planting. Land in the urban region is rare,

expensive, and cannot meet the requirements of extensive cultivating. Many

urban dwellers use cultivation boxes for cultivation or even environmental

afforestation.

A traditional cultivation box only has one container. When multiple

traditional cultivation boxes are used for cultivating, the arrangement of the

traditional cultivation boxes should be made according to limitation of land and

space. Since the traditional cultivation box lacks components for stacking, the

traditional cultivation boxes are only suitable for side-by-side arrangement.

When two of the traditional cultivation boxes are simply stacked, there is no

space between the two traditional cultivation boxes due to lack of the

components for stacking. A lower one of the two traditional cultivation boxes

has poor ventilation and cannot acquire sufficient light. Therefore, the traditional

boxes are not suitable for stacking and are limited in space utilization. The

traditional cultivation boxes have to be supported by an additional frame for stacking. Moreover, the traditional cultivation boxes lack components for combining two adjacent containers of the two traditional cultivation boxes side by side. Therefore, the two adjacent containers offset easily.

A conventional cultivation box has been invented for improving

abovementioned drawbacks of the traditional cultivation boxes. The

conventional cultivation box has a container and combination components

disposed on the container of the conventional cultivation box. The combination

components of the conventional cultivation box are directly arranged on the

container of the conventional cultivation box, so when two conventional

cultivation boxes are combined, one of the two conventional cultivation boxes

has to be moved to combine with the other one of the two conventional

cultivation boxes. Moving the container of the conventional cultivation box

takes a lot of labor, especially when the container of the conventional cultivation

box has objects contained therein.

To overcome the shortcomings of the conventional cultivation box, the

present disclosure provides a cultivation assembly to mitigate or obviate the

aforementioned problems.

SUMMARY

The main advantage of the present disclosure is that it provides a

cultivation assembly that is easy to be assembled and saves labor.

According to a first aspect, there is provided a cultivation assembly

comprising a container having a surrounding wall erectly disposed and having

multiple side plates, each one of the multiple side plates having a top face, and

multiple combining holes defined in the top face of the side plates, at least one first engaging structure facing outside of the container, an engaging member configured to connect the container of another cultivation assembly side by side, and having two second engaging structures facing opposite directions, and each one of the two second engaging structures is capable of engaging with one of the at least one first engaging structure, and a combining unit having two engaging rows, each engaging row having multiple engaging protrusions capable of respectively engaging with the multiple combining holes of one of the multiple side plates. The container of the cultivation assembly is capable of being connected to the container of another cultivation assembly side by side via the engaging member and without wasting a lot of labor to move the container.

Other objects, advantages, and novel features of the invention will

become more apparent from the following detailed description when taken in

conjunction with the accompanying drawings.

annular wall 941A, a dividing plate 943A erectly disposed within the annular

wall 941A, a first space Si and a second space S2 divided by the dividing plate

943A, and a filtering sponge 944A. The filtering box 94A is disposed within the

container 10 of the upper cultivation assembly 1. The conducting pipe 92A

communicates with the second space S2 of the filtering box 94A and

communicates with the inside of the container 10 of the upper cultivation

assembly 1 via the second space S2. The introducing set 93A is disposed within

the first space S Iof the filtering box 94. The filtering sponge 944A is disposed

within the second space S2 of the filtering box 94A.

The recycling system 90A in the fourth embodiment makes water

recycle between the two containers 10 of the upper cultivation assembly 1 and the lower cultivation assembly 1. The container 10 of the lower cultivation assembly 1 can be applied for cultivating fish, shrimp, or other small animals.

The container 10 of the upper cultivation assembly 1 can be applied to cultivate

plants. The nitrogen in excretion of the fish and the shrimp can be drawn with

water by the pump 91A. With reference to Fig. 19, water from the container 10 of

the lower cultivation assembly 1 enters the container 10 of the upper cultivation

assembly 1 via the conducting pipe 92A. Water flows through the filtering box

94A. The filtering sponge 944A disposed within the second space S2 of the

filtering box 94A blocks solid excretion. Nitrogen within water is turned into

ammonia or nitrate through nitrogen fixation of bacteria. The ammonia or the

nitrate can be absorbed by the plants and provide nutrition to the plants. Purified

water enters the introducing set 93A and returns to the container 10 of the lower

cultivation assembly 1 by siphonage. The plants cultivated within the container

10 of the upper cultivation assembly 1 can thrive without fertilization. The fish

or shrimp cultivated within the container 10 of the lower cultivation assembly 1

is provided with purified water.

Even though numerous characteristics and advantages of the present

invention have been set forth in the foregoing description, together with details

of the structure and features of the invention, the disclosure is illustrative only.

Changes may be made in the details, especially in matters of shape, size, and

arrangement of parts within the principles of the invention to the full extent

indicated by the broad general meaning of the terms in which the appended

claims are expressed.

It will be understood that the term "comprise" and any of its derivatives

(eg comprises, comprising) as used in this specification is to be taken to be

inclusive of features to which it refers, and is not meant to exclude the presence

of any additional features unless otherwise stated or implied.

The reference to any prior art in this specification is not, and should not

be taken as, an acknowledgement or any form of suggestion that such prior art

forms part of the common general knowledge.
