Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilization device technology, and in particular to a high-efficiency fertilization device for greenhouse vegetables. Background Technology
[0002] A vegetable greenhouse is a frame-and-film structure with excellent heat preservation properties. Its emergence has enabled people to eat off-season vegetables. The fertilizers needed for vegetables are generally divided into two types: foliar fertilizer, which is liquid fertilizer, sprayed on the vegetables, and soil fertilizer, which is solid fertilizer, sprinkled on the soil. The two types of fertilizers have different compositions, and the fertilization methods will also change accordingly due to the changes in the growth cycle of the plant.
[0003] According to utility model patent CN214800791, an automatic fertilization device for greenhouse cultivation includes two connecting plates, with two sliding rods connected between them. A support frame is slidably mounted on each of the sliding rods. A rack is installed on one of the sliding rods, and a fixing block is installed on the support frame. A guide rod rotatably passes through the fixing block, and a gear is installed at one end of the guide rod. The gear meshes with the rack through its teeth. A motor is installed on the support frame. This utility model uses the motor to drive the gear to rotate. Because the gear meshes with the rack, and the rack remains fixed on the sliding rod, the rotation of the gear drives the support frame to slide along the sliding rod. A flexible hose delivers nutrients into the conduit, which is then sprayed out through the nozzle. As the support frame moves, it achieves uniform spraying of crops in the greenhouse, improving work efficiency and reducing the labor required of workers.
[0004] Although the above-mentioned technical solution can realize automatic fertilization of greenhouse vegetables, it cannot adjust the height of water and fertilizer spraying according to the growth cycle of vegetables in actual use. When fertilizing, it can only fertilize the leaves of vegetables from above, making it difficult to fertilize the vegetables more comprehensively, resulting in poor fertilization effect. Utility Model Content
[0005] The purpose of this invention is to provide a high-efficiency fertilization device for greenhouse vegetables. When fertilizing vegetables in the greenhouse, the device can not only flexibly adjust the fertilization height according to the growth cycle of the vegetables, but also provide more comprehensive fertilization and improve the fertilization effect.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A high-efficiency fertilization device for greenhouse vegetables includes two U-shaped frames arranged opposite each other, and linear motors respectively installed on the upper end of the U-shaped frames and cooperating with them. An I-shaped slide rail is provided between the upper ends of the two linear motors.

On both sides of the vegetable bed, the water pumps are then activated to draw water and fertilizer through the inlet pipe, and then deliver it to the spraying assembly for fertilization through the outlet pipe. At the same time, the drive motor is activated to move the carriage forward along the slide rail. As the carriage moves, the winding assembly rotates synchronously with the second pulley and the second belt, thereby controlling the opening and closing of the water pipe and preventing it from dragging on the ground during fertilization. Once the vegetables on one bed have been fertilized, the linear motor is activated to move the slide rail to the vegetables on the other bed for fertilization.
