Description

Technical Field

[0001] This utility model relates to the field of agricultural facility technology, and in particular to a three-dimensional cultivation rack for soilless cultivation of blueberries. Background Technology

[0002] In the process of large-scale development of the blueberry industry, hydroponics technology has become an important means to improve the quality and yield of blueberries due to its ability to precisely control nutrient content and water conditions. Among these technologies, the multi-layered cultivation rack, as the core equipment of the hydroponics system, significantly increases the planting density per unit space through its multi-layered layout, effectively solving the problem of low land utilization in traditional flat cultivation, and is widely used in facility agriculture. However, existing multi-layered cultivation racks for blueberry hydroponics have the following drawbacks in practical application: 1. As the core carrier for blueberry root growth and nutrient absorption, the cultivation trough accumulates root metabolic residues and unabsorbed nutrients after long-term use. These substances are prone to microbial growth in humid environments, which not only pollutes the water quality and causes abnormal fluctuations in the EC value of the nutrient solution, but also easily leads to diseases such as root rot, directly affecting the healthy growth of blueberry roots. However, existing multi-layered cultivation racks generally lack automatic cleaning functions, and the cultivation troughs are mostly designed as fixed or semi-fixed, requiring manual cleaning. Disassembling layer by layer presents problems such as high labor intensity, cumbersome operation, and high labor costs; 2. Blueberries naturally produce fallen leaves during their growth cycle. Due to the lack of a targeted collection structure, the existing three-dimensional cultivation racks allow the fallen leaves to fall directly to the ground or into the gaps between the lower cultivation tanks. The fallen leaves not only become a breeding ground for pests and diseases, but also require regular manual cleaning. Due to the multi-layered structure of the three-dimensional cultivation racks, the cleaning process requires repeated work between different levels, which is difficult and inefficient. Especially in large-scale orchards, leaf cleaning has become a prominent problem restricting management efficiency. Utility Model Content

[0027] Working Principle: When using this invention, blueberries can be planted in cultivation baskets 236. The water inlet pipe 14 is connected to the dosing system. After the dosing system prepares the nutrient solution required for growth, it is delivered through the water inlet pipe 14 to the water inlet hole 27, and then into the liquid collection tank 22. The wastewater pipe 16 is connected to the wastewater treatment system. When discharging wastewater, the electric valve 240 is opened, and the dosing system sends clean water to rinse the liquid collection tank 22. Wastewater is sent through the wastewater hole 29 and the electric valve 240 into the wastewater pipe 16, and then centrally sent to the wastewater treatment system for harmless treatment. The overflow pipe 15 is connected to the chemical recovery system. When the nutrient solution in the liquid collection tank 22 reaches the overflow hole 28, the excess nutrient solution flows through the overflow hole 28 into the overflow pipe 15, and is then centrally sent to the chemical recovery system. The recycling process is carried out. When cleaning up the waste, the motor 211 needs to be started. The motor 211 drives the first connecting shaft 212. The first connecting shaft 212 drives the synchronous belt 214 through the first pulley 213. The synchronous belt 214 is driven on the second pulley 215. The second pulley 215 is installed by the second connecting shaft 216. The driven synchronous belt 214 will drive the pusher plate 217 to move along the waste collection trough 24. By rotating the motor 211 in both directions, the pusher plate 217 can move back and forth. The fallen leaves of blueberries slide into the waste collection trough 24 through the inclined plate 25 and the inclined surface of the cover plate 232. The moving pusher plate 217 pushes the fallen leaves into the connecting pipe 210, and then slides into the waste discharge pipe 11 through the branch pipe 12, and finally into the waste collection bucket 13, thereby realizing the centralized collection of fallen leaves.During the movement of the pusher plate 217, the connecting rod 229 on it slides within the through groove 23. The connecting rod 229 drives the fourth connecting shaft 226, which in turn drives the mounting bracket 219. The mounting bracket 219 slides along the first guide rail 218. When the motor 211 rotates clockwise, the pusher plate 217 and the mounting bracket 219 move to the right. When the motor 211 rotates counterclockwise, the pusher plate 217 and the mounting bracket 219 move to the left. The left and right directions are used for easy distinction. When the mounting bracket 219 moves to the right, the roller 231 does not contact the second guide rail 234. At this time, the first scraper 222 and the second scraper 228 are in contact with the liquid collection tank 22. The inner wall of the liquid-containing tank 22 is cleaned. When the mounting bracket 219 moves to the end position of the second guide rail 234, the roller 231 pushes away the stop block 237, and the stop block 237 deflects on the fixed seat 238 until the mounting bracket 219 moves to the limit position. The roller 231 disengages from the stop block 237, and under the action of the second spring 239, the stop block 237 returns to its original position until it is limited by the end of the second guide rail 234. At this time, the motor 211 rotates counterclockwise, the mounting bracket 219 moves to the left, and the roller 231 rolls along the stop block 237 onto the second guide rail 234. During this process, the roller 231 will drive the rocker arm 230 on it to deflect, and the rocker arm 230 will drive the fourth connecting shaft 226 to deflect. As the first spring 227 twists and deforms, the second scraper 228 on the fourth connecting shaft 226 deflects accordingly, disengaging from the inner wall of the liquid-holding tank 22. The fourth connecting shaft 226 drives the first gear 224 via the second gear 225, and the first gear 224 drives the connecting block 221 via the third connecting shaft 220. The connecting block 221 deflects within the clearance groove 223, causing the first scraper 222 on the connecting block 221 to deflect accordingly, disengaging from the inner wall of the liquid-holding tank 22. When the roller 231 rolls out of the first end of the second guide rail 234, the fourth connecting shaft 226 resets under the action of the first spring 227, causing the second scraper 228 and the first scraper 222 to reset as well. Plate 228 and the first scraper 222 re-adhere to the inner wall of the liquid-containing tank 22, and the above process is repeated to clean the inner wall of the liquid-containing tank 22. The second scraper 228 and the first scraper 222 can push the dirt closer to the wastewater hole 29, while avoiding pushing the dirt away from the wastewater hole 29 during reciprocating movement. The bracket 1 is the main support structure, the shell 21 is the main outer shell of the cultivation tank assembly 2, the reinforcing plate 26 is used to support the inclined plate 25, the positioning block 233 is used to position the cover plate 232, and the mounting hole 235 is used to accommodate the cultivation basket 236. The dosing system, wastewater treatment system, and chemical recovery system are common knowledge in the field and will not be described in detail here.
