Description

Technical Field

[0001] The invention relates to the technical field of plant cultivation equipment, in particular to a three-dimensional planting rack for a plant factory. Background Art

[0002] Plant factories are efficient agricultural systems that achieve continuous year-round production of crops through high-precision environmental control within the facility. They use intelligent computers and electronic sensor systems to automatically control environmental conditions such as temperature, humidity, light, CO2 concentration, and nutrient solution for plant growth, making the growth and development of plants in the facility unrestricted or rarely restricted by natural conditions. Plant factories cannot grow and cultivate plants without planting racks, the most common of which are flat-lay, triangular, and layered racks.

[0003] At present, most of the existing plant planting racks are fixed in design, and the spacing between each cultivation layer is fixed. In order to ensure that the plants are not restricted by the height spacing of the planting racks during their growth, the spacing between each cultivation layer on the planting rack is relatively large, and the spraying ports for spraying water and fertilizer are mostly located above the plants. For example: a Chinese patent with an authorization announcement number of CN210382016U discloses a three-dimensional landscape plant planting rack that can quickly update plants, including a rack body and a planting trough, the inner walls of both sides of the rack body are connected to a second driven pulley at the corners through a rotating shaft, and the three second driven pulleys on the same side of the rack body are connected by a conveyor belt transmission. Although it is possible to spray water and fertilize plants in different growth stages, due to the fact that the plants are planted in the seedling stage The plants are relatively short, and the fixed spraying ports are easy to damage the plants during the fertilization process. When the existing planting racks are watering and fertilizing the plants in each cultivation layer, it is necessary to add substances such as nutrient solution to the water resources, and then spray them on the plants after forming water-fertilizer. In order to ensure the eligibility of the water-fertilizer, it is necessary to pre-mix the water resources with added nutrient solution and other substances through a stirring structure before spraying them. In addition, the fertilizer and water required to be sprayed on the plants in different growth cycles are all controlled by various control devices to control the spraying amount and spraying water intensity, which not only further increases the production cost of the product, but also the design of the control program is relatively complicated when the equipment is running, and it is easy to have operating failures and affect the safe cultivation of plants.

[0047] See also Figure 6-Figure 7 In the embodiment of the present invention, the driving member 5 includes an electric push rod 51 disposed on the bottom shell wall of the top plate 12. A connecting arm 52 is installed at the output end of the electric push rod 51, and an integration plate 53 is installed on the side of the connecting arm 52 away from the electric push rod 51 through screws. A return groove is provided on the integration plate 53, and a plurality of rod bodies are slidably connected in the return groove, and the left end of each rod body is fixedly connected to the corresponding moving member 27.

[0048] A guide groove is provided on the bottom shell wall of the top plate 12, and a guide block is slidably connected in the guide groove, and the bottom of the guide block is fixedly connected to the connecting arm 52. The guide groove and the guide block are provided to guide and support the movement of the connecting arm 52.

[0049] The working principle of the present invention is: when cultivating plants, the seedling base 25 loaded with plants is placed on the base plate 21 of each cultivation layer 2 in turn, and then the height of the frame 22 in each cultivation layer 2 is uniformly adjusted through the external control system. The external control system simultaneously turns on the motors 31 in the multiple lifting components 3 set in the product, so that the corresponding screw rods 32 rotate. During the rotation of the screw rod 32, since each inner groove sleeve 33 is locked and connected with the corresponding protrusion at this time, the corresponding frame 22 in each cultivation layer 2 is adjusted in height during the rotation of the screw rod 32, so that it adapts to the current growth period of the plant.

[0050] Then, under the operation of the external control system, the lamp main body 26 arranged in each cultivation layer 2 is switched on and off to meet the lighting requirements for plant growth.

[0051] When the frame 22 in each cultivation layer 2 is adjusted in height, the spraying assembly and the fertilizing assembly 210 loaded thereon move accordingly. When the spraying assembly moves with the frame 22, the gear ring 283 in the spraying member 28 is meshed with the corresponding fixed rack 285 for transmission, so that the switching tube 282 is rotated when the frame 22 is raised and lowered, thereby realizing the switching adjustment of the discharge port group on the switching tube 282. When the height adjustment of the frame 22 is completed according to the growth status of the plants in the seedling base 25, the discharge port group of the switching tube 282 adjusted accordingly is just suitable for the water and fertilizer spraying of the current plants.

[0052] When the frame 22 is raised and lowered, the push rod 2103 arranged thereon moves in combination with the return spring while in contact with the bending plate 211, thereby achieving displacement adjustment of the rubber plug loaded thereon.

[0053] When the frame 22 is raised to the maximum mileage, the push rod 2103 is separated from the bending plate 211 under the action of the return spring, and the multiple rubber plugs arranged thereon are separated from the corresponding notches, so that the multiple storage cavities in the liquid tank 2101 are connected to each other, thereby meeting the amount of water and fertilizer spraying for the plants in the growth period. The discharge port group with the largest discharge port aperture on the switching tube 282 is in a released state, which can facilitate the passage of water and fertilizer, thereby facilitating the rapid spraying of water and fertilizer.

[0054] When poisonous plants need to be sprayed with water and fertilizer, the nutrient solution and acid solution added to the water resources are adjusted according to the current growth needs of the plants, so that the mixed water and fertilizer can be suitable for the current growth needs of the plants.

[0055] When configuring water and fertilizer, the EC value and pH value of water and fertilizer are first set in the external control system, and then the amount of nutrient solution and acid solution required to achieve the predetermined RC value and pH value is calculated by the external control system. The control system predetermines the opening time of the nutrient solution control valve 47 and the acid solution control valve 48 in the mixing mechanism 4 according to the calculation structure. Then the control system starts the external water pump to transport water resources into the mixing box 41 in the mixing mechanism 4 through the water inlet pipe. When the water resources enter the interior of the mixing box 41, they impact the impeller 42, causing the impeller 42 to rotate inside the mixing box 41. After the nutrient solution control valve 47 and the acid solution control valve 48 are opened, the nutrient solution and the acid solution stored in the corresponding liquid storage tank 46 enter the inner cavity of the bearing sleeve 44 through the liquid infusion tube 49, and then enter the interior of the sleeve 43 through the notch on the sleeve 43, thereby entering the accommodating cavity of the impeller 42, and discharged from the discharge port to the interior of the mixing box 41, and under the action of the rotation of the impeller 42, the water and fertilizer are efficiently mixed with water resources to form water fertilizer. The water fertilizer enters the liquid tank 2101 of the fertilization assembly 210 in each cultivation layer 2 through the cooperation of the water outlet pipe and the hose.

[0056] When it is necessary to spray and fertilize the plants, the electric control one-way valve on the discharge pipe and the shunt pipe 2106 on the storage cavity is opened. The electric push rod 51 in the driving member 5 performs reciprocating telescopic activities, and then drives the integration plate 53 to perform synchronous activities through the connecting arm 52. The integration plate 53 synchronously realizes the reciprocating motion of the slide plate 271 of the moving member 27 in each cultivation layer 2 during the movement. When the slide plate 271 moves, the active rack 272 and the fixed plate 273 are synchronously moved. During the movement of the fixed plate 273, the motion rod 2105 drives the push plate 2104 to reciprocate through the cooperation of the chute and the round rod. During the activity of the push plate 2104, the water and fertilizer in the storage cavity enter the switching pipe 282 under the cooperation of the discharge pipe and the shunt pipe 2106. Then, the spraying of water and fertilizer is realized under the action of the nozzle on the discharge port group of the switching pipe 282 and the fixed pipe 281.

[0057] The active rack 272 is meshed with the driven gear 293 in the adjusting member 29 to rotate and adjust. Then, the fixed pipe 281 in the spraying member 28 is reciprocated by the combination of the swing arm 292 and the movable arm 291, so as to spray the plants in each cultivation layer 2 with water and fertilizer uniformly.

[0058] During the working process, after the sprinkler irrigation is completed, the plant factory uses the dehumidification system to stabilize the humidity inside the plant factory within the humidity range suitable for plant growth, avoiding excessive humidity affecting the transpiration rate of the plants.

[0059] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
