Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to a liquid fertilizer quantitative feeding device. Background Technology

[0002] Vertical farming is an agricultural technique that cultivates plants in a vertical gradient, without occupying flat land, by using pillars erected around the perimeter or by constructing trellises or hanging structures. This method makes full use of space, increases land utilization, and improves yield per unit area.

[0003] A known Chinese patent (application number: CN202020444529.3) discloses a three-dimensional planting rack suitable for agricultural greenhouses, relating to the agricultural field. It includes a support frame, several water troughs, several support plates, several planting cups, a fertilization system for replenishing water and nutrients, and a pesticide spraying system. The water troughs are vertically spaced at equal intervals on both sides of the support frame. The planting cups are horizontally spaced at equal intervals at the bottom of the support plates, with their tops penetrating the support plates. Each planting cup has dense perforations circumferentially. The support plates are detachably connected to the support frame via a fastening mechanism. The planting cups correspond vertically to the water troughs. The fertilization system is connected to each water trough, and the pesticide spraying system corresponds to the top of each planting cup. By vertically arranging multiple rows of planting cups on the support frame within the greenhouse, the planting area is transformed from a single surface layer to a multi-layered structure, improving the utilization rate of greenhouse resources and increasing planting profits.

[0004] However, in implementing the relevant technology, the above-mentioned three-dimensional planting rack suitable for agricultural greenhouses has the following problems: the moisture, pH value and acidity of the planting soil cannot be detected before fertilization, so the amount and type of fertilizer cannot be adjusted according to actual needs, which may lead to over-fertilization or under-fertilization, which not only wastes fertilizer resources, but may also damage crops. Therefore, a liquid fertilizer quantitative feeding device was proposed. Utility Model Content

[0005] This invention proposes a liquid fertilizer quantitative feeding device, which solves the problem in related technologies that the moisture, pH value and acidity of the planting soil cannot be detected before fertilization, thus making it impossible to adjust the amount and type of fertilizer according to actual needs, which may lead to over-fertilization or under-fertilization, wasting fertilizer resources and potentially harming crops.

[0006] The technical solution of this utility model is as follows: a liquid fertilizer quantitative feeding device, comprising: an L-shaped support;

[0007] Multiple electric telescopic rods are fixedly installed on the rear side of the L-shaped bracket from top to bottom. The output ends of the multiple electric telescopic rods are movably connected to the planting shell through the L-shaped bracket. Stabilizing plates are slidably connected to the L-shaped bracket from top to bottom through multiple through slots. The stabilizing plates are connected to the planting shell.

[0008] A lifting mechanism is installed on the bottom wall of the L-shaped bracket. A humidity sensor and a pH sensor are installed on the lifting mechanism. A spraying mechanism is also installed on the lifting mechanism. A feeding mechanism is installed on the rear side of the L-shaped bracket.

[0009] Preferably, the lifting mechanism includes two sliding plates that are fixedly installed on the inner bottom wall of the L-shaped bracket. The two sliding plates are slidably connected to a slide plate, and the bottom of the slide plate is connected to a humidity sensor and a pH sensor.

[0010] Preferably, a motor is fixedly installed on the inner bottom wall of one of the two slide plates, and a lead screw is fixedly connected to the output end of the motor. The outer wall of the lead screw is threadedly connected to the slide plate.

[0011] Preferably, the spraying mechanism includes a tube fixedly installed on the top of the slide plate, and the outer wall of the tube is provided with a plurality of nozzles.

[0012] Preferably, the feeding mechanism includes a storage box fixedly installed on the rear side of the L-shaped bracket. The storage box is located between the plurality of electric telescopic rods. A pump body is fixedly installed on the top of the storage box. A hose is fixedly connected to the output end of the pump body. A flow sensor is provided on the outer side wall of the hose. One end of the hose is connected to the pipe body. The input end of the pump body extends into the interior of the storage box.

[0013] Preferably, a feed pipe is fixedly installed on the top of the storage tank, the feed pipe is located on one side of the pump body, and a sealing cap is connected to the top of the outer wall of the feed pipe through an external thread.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] Before fertilization, the planting shell is moved outward by activating the electric telescopic rod, and the linkage stabilizing plate slides in the channel. The stabilizing plate makes the planting shell more stable when it moves. When the planting shell moves below the humidity sensor and pH sensor, the lifting mechanism drives the humidity sensor and pH sensor to move downward, so that the detection ends of the humidity sensor and pH sensor can detect the soil moisture, pH value and acidity. After the detection is completed, the amount and type of fertilizer are adjusted according to the detection data, thereby preventing the problems of over-fertilization or under-fertilization.

After the detection is completed, the amount and type of fertilizer are adjusted according to the detection data, thereby preventing the problem of over-fertilization or under-fertilization. At the same time, the position of the planting shell 3 can be adjusted by the electric telescopic rod 2, so that the positions of multiple planting shells 3 are different, so that the crops planted in each planting shell 3 can receive sufficient sunlight and better perform photosynthesis.
