Description

Technical Field

[0001] The present invention relates to the technical field of soilless cultivation devices, and particularly to a vegetable cultivation device. Background Art

[0002] Soilless cultivation refers to a cultivation method that does not use natural soil but uses a substrate or only uses a substrate during seedling raising and uses nutrient solution for irrigation after planting. Since soilless cultivation can artificially create a good rhizosphere environment to replace the soil environment, effectively prevent soil-borne diseases and physiological disorders caused by soil salt accumulation, fully meet the needs of crops for mineral nutrition, water, gas and other environmental conditions, and the basic materials used for cultivation can be recycled, it has the characteristics of water saving, fertilizer saving, labor saving, high yield and good quality.

[0003] The prior art such as Chinese Patent No. CN201710496652.2 discloses a three-dimensional household vegetable planter, including a three-dimensional household vegetable planter body; the three-dimensional household vegetable planter is composed of a base, a liquid storage tank, a seedling raising layer, a seedling tray, a nutrient solution pipeline, a planting cup, a planting layer, an LED lamp, a speaker, and a display screen; the base is composed of a support frame, a seedling raising layer and a planting layer. The present invention uses the gravity principle to make the nutrient solution pumped to the top layer flow back naturally, forming a circulating system for nutrient supply, and supplies nutrients regularly and quantitatively to save energy while ensuring nutrient absorption; a special full-spectrum LED lamp for vegetable growth irradiates vegetables for 6-8 hours every day imitating the solar spectrum, effectively providing the light energy required for vegetable growth; and the present invention can complete operations indoors, occupies a small area, has low technical requirements, can realize the effect of no need for special care, safety, environmental protection and no pollution, and can purify the air.

[0004] The planting layer (referred to as a planting rack in this application) in the above prior art is fixedly installed on the base, so that its quantity is fixed and cannot be changed according to actual needs. Since vegetable varieties on the same base cannot be mixed and planted together, the fixedly installed planting layer will cause some planting layers to be idle, resulting in waste of resources. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problems existing in the prior art and provide a vegetable cultivation device, which can achieve at least a certain degree of improvement in the operation efficiency.

[0006] To achieve the above technical purpose and reach the above technical effect, the present invention is realized through the following technical solutions:

[0007] A vegetable planting device, comprising a frame body, on which a plurality of planting racks are horizontally arranged in columns, a plurality of planting grooves are provided on the planting racks, a threaded column is vertically provided at each of the opposite ends of the frame body, a plurality of lifting racks are jointly penetrated on the two threaded columns, the plurality of lifting racks are arranged in columns on the frame body and are provided with through holes for the threaded columns to freely pass through, the outer contour of the lifting rack is generally U-shaped, and a clamping groove for the two ends in the width direction of the planting rack to slide and engage is provided on the defective part in the middle thereof. A plurality of main water pipes are provided on the frame body, and a plurality of spray heads communicated with the main water pipes and corresponding to the plurality of planting racks are arranged in an array on the main water pipes.
