Description

Technical Field

[0001] This utility model relates to the field of plant cultivation, specifically to a pull-out basket type planting cart. Background Technology

[0002] In modern agricultural planting and home gardening, the functionality and practicality of planting devices have always been the core direction of technological development. Currently, planting equipment on the market generally suffers from insufficient drainage and aeration. Traditional planting containers often use a closed-bottom structure, and even when drainage holes are provided, their improper placement often leads to water accumulation. Especially during continuous rainfall or excessive irrigation, prolonged soaking of plant roots can easily cause root rot, mold, and other problems, severely impacting plant survival rates. For example, existing potted containers typically only have a single drainage hole in the center of the bottom, which not only has low drainage efficiency but also fails to create an effective air circulation channel, leading to root hypoxia. This problem is particularly prominent in large-scale planting scenarios.

[0003] Meanwhile, the lack of a nutrient solution recycling mechanism has become a significant factor in resource waste. In traditional planting methods, excess irrigation water carries nutrients directly out, resulting in the loss of nutrient solution resources and potential pollution of the surrounding environment. Especially in home gardening or small-scale planting scenarios, users find it difficult to collect and reuse the discharged nutrient solution, leading to increased planting costs and contradicting the concept of green and environmentally friendly development.

[0004] The conflict between mobility and stability has long existed in planting devices. Traditional planting boxes or flower beds are mostly fixed structures, which cannot flexibly adjust their positions according to environmental factors such as light and temperature.

[0005] In addition, the space utilization and structural durability of planting equipment also face technical bottlenecks. Traditional multi-layer planting equipment mostly adopts a stacked design, and there is a lack of independent drainage and ventilation systems between each layer, which can easily lead to cross-infection of pests and diseases, and the growth of plants at the bottom layer is limited due to insufficient light.

[0006] In conclusion, developing a planting device that combines efficient drainage and aeration, nutrient solution recycling, flexible movement and stable fixation, high space utilization and durability has become an urgent technical problem to be solved in the field of horticulture.

Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Other embodiments are considered and may be implemented without departing from the scope or spirit of the present invention. Therefore, the following detailed description is non-limiting.

[0039] As mentioned above, existing planting devices suffer from poor drainage and aeration, easily leading to root rot in plants; nutrient solutions cannot be recycled and pollute the environment; mobile devices are unstable and inconvenient to fix; planting equipment is mostly a fixed structure, resulting in low space utilization; the materials lack corrosion resistance and are prone to aging and rusting with long-term use; traditional planting methods are difficult to manage; plants are easily damaged in high temperatures and water shortages; and they cannot effectively cool the plant roots when the external temperature is high. Therefore, a pull-out basket-style planting cart is provided, featuring an openable drainage outlet and permeable holes, the ability to recycle nutrient solutions, automatic soil watering, flexible movement with one-button locking, and is economical, durable, and easy to manage.

[0040] According to the technical solution of this utility model, a pull-out basket planting cart is provided, comprising:

[0041] An open-top container has multiple vents at its top, a liquid level observation mirror on its side, an openable drain outlet at its bottom, and multiple wheels.

[0042] An open inner basket is disposed inside the open box body, with the opening direction being the same as that of the open box body. The open inner basket is provided with a water-absorbing rope at its bottom and has multiple water-permeable holes on its bottom and sides.

[0043] Figure 1 This shows a schematic diagram of the external structure of a pull-out basket planting cart 100 according to one embodiment of the present invention; Figure 2 A schematic perspective view of the open box 1 of a pull-out basket planting cart 100 according to one embodiment of the present invention is shown. Figure 3 A schematic perspective view of the open inner basket 2 of a pull-out planting cart 100 according to one embodiment of the present invention is shown.

[0044] like Figures 1-3 As shown, the pull-out basket planting cart 100 includes: an open-top box 1 with multiple ventilation holes 3 on its upper part (only the ventilation holes located on the front side of the open-top box 1 are shown for clarity), a liquid level observation mirror 4 on its side, an openable drain outlet 5 at the bottom, and multiple wheels 6; an open-top inner basket 2 disposed inside the open-top box 1, with the opening direction D1 being the same as the opening direction D2 of the open-top box 1, the inner basket 2 having three sets of absorbent ropes 7 at its bottom, and multiple drainage holes 8 on its bottom and sides. The open-top box 1 has stainless steel handles 9 on two opposite sides along its length. The inner basket 2 has stainless steel handles 10 on two opposite edges along its length.

[0045] Specifically, the core structure of this utility model lies in the double-layer design of an open box and an open inner basket, forming a nested planting space. The open box serves as the outer support structure, with an openable drain outlet at its bottom. This drain outlet uses a stainless steel gate valve structure, and its opening and closing are controlled by a handle.
