High-density three-dimensional plant cultivation apparatus

Abstract

The invention belongs to the technical field of vertical agriculture, and particularly relates to high-density three-dimensional plant cultivation apparatus. The apparatus mainly comprises movable plant frames, movable lamp frames, and a load-bearing beam, wherein each movable plant frame and each movable lamp frame can move along the load-bearing beam, three-dimensional cultivation plates are installed on two sides of each movable plant frame, a water collection trough is installed below each movable plant frame, and a nutrient solution delivery pipeline and atomizing nozzles are installed ina space formed by the cultivation plates on two sides of each movable plant frame. The cultivation plates are of the stepped design, and are provided with a plurality of planting holes. Each movableplant frame and each movable lamp frame are of the standard modular design, and can be assembled according to needs and actual conditions of a site. According to the apparatus, an operation channel isformed through each movable plant frame and the corresponding movable lamp frame, and thereby the production efficiency is greatly improved. An aerosol form is adopted to simplify the supply of a nutrient solution, and the stepped design of the cultivation plates improves the plant cultivation density. The plant frames and the lamp frames are of the standard modular design, so that the simplicityof construction is improved, and thereby the apparatus can adapt to the needs of different scenarios, and the scalability is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of vertical agriculture, in particular to a high-density three-dimensional plant cultivation device. Background technique [0002] With the continuous improvement of the public's demand for the quantity and quality of agricultural products, vertical farming has developed rapidly. Improving planting efficiency in a controlled environment with limited space is an important direction for the development of vertical farming. The existing three-dimensional plant cultivation mostly adopts the form of multi-layer hydroponics, and its devices are relatively complicated, and there is a large space reserved for the operation of manual and mechanical equipment, and there is also a large room for optimization of nutrient solution supply.

The existing three-dimensional plant cultivation mostly adopts the form of multi-layer hydroponics, the device is relatively complicated, the operation of manual and mechanical equipment has a large space, and the supply of nutrient solution also has a large room for optimization

[0003] Most of the existing multi-layer hydroponic planting racks occupy a large area and are mostly used for planting plants in a fixed space. Once the planting racks are designed and installed, it is difficult to refit them, and it is difficult to adapt to the ever-changing cultivation needs in the plant cultivation process. ; and most of the large-scale plant cultivation racks are integrally formed structures, usually composed of planting layers, lamps, nutrient solution supply systems, etc. The system integration is high. Once a module fails, the entire planting rack will be unusable, and the use and maintenance costs are high.

The existing cultivation racks must reserve an operating area for personnel and mechanical equipment during installation. For example, at least 50 cm of operating channels must be reserved between adjacent plant racks. Planters need regular care and sampling during the plant cultivation process. Therefore, it is difficult to increase the planting density by using this method of plant racks. It can only set multiple planting layers on the height of the space to increase the planting density, and there is still a lot of room for development in increasing the planting density.

In addition, most of the existing plant cultivation layers are cultivated in a horizontal form, and the planting holes of each plant in the cultivation layer need to be separated by a certain distance to prevent adjacent plants from competing for nutrients and provide enough space for plant growth. Therefore, horizontal The planting density of the cultivation layer is relatively low

The existing hydroponic planting frame is usually equipped with a hydroponic tank body, and the nutrient solution is pumped into the tank by a water pump for hydroponic cultivation. The nutrient solution supply system is complicated, because the nutrient solution in the hydroponic tank is easy to grow microalgae under the irradiation of LED lights. , the nutrient solution needs to be replaced regularly, and the hydroponic system using this method consumes a lot of nutrient solution, which is not conducive to reducing costs
