Description

Technical Field

[0001] This invention relates to the field of soilless cultivation technology, specifically to a soilless cultivation device and a soilless cultivation method. Background Technology

[0002] Soilless cultivation is a new crop cultivation technology that has developed in recent decades. Crops are not grown in soil, but rather in an aqueous solution containing dissolved minerals (nutrient solution); or in a certain cultivation substrate using a nutrient solution. With appropriate cultivation equipment and management practices, crops can grow normally and achieve high yields. Because it does not use natural soil but instead uses nutrient solutions for cultivation, it is called soilless cultivation.

[0003] Existing hydroponic systems cultivate plants by placing nutrient solutions in culture boxes. However, when the nutrient solution needs to be replaced, it is necessary to remove the solution from each box and add it back in. This not only increases the workload of staff but also reduces work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a soilless cultivation device and a soilless cultivation method thereon to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soilless cultivation device, comprising a base, a liquid storage tank at the top of the base, a support plate fixed to the top of the base, support blocks fixed to both sides of the support plate, the bottom of the support blocks fixed to the top of the base, a cultivation box fixed to the inner side of the support plate, multiple sets of equally spaced partitions fixed to the inner wall of the cultivation box, a fixing plate fixed to the side wall of the base, a water pump fixed to the top of the fixing plate, and a filter screen fixed to the inner wall of the liquid storage tank. Through the coordination of the water pump, connecting pipe, outlet pipe, main pipe, and spray head, nutrient solution can be sprayed onto the plants. By setting up a drain pipe, the nutrient solution in the cultivation box can flow to the next layer of cultivation boxes for further cultivation, thus allowing for the cultivation of multiple plants. The filter screen can filter impurities from the used nutrient solution, allowing the filtered nutrient solution to flow to the bottom of the filter screen for recycling. This method not only achieves high efficiency but also reduces the labor required for workers. A cleaning mechanism is provided on the top of the base, and a groove is formed on the base. A stirring mechanism is provided on the groove. The cleaning mechanism includes:

[0006] A connecting block is fixed to the top of the base. A reciprocating screw is rotatably mounted on the right side of the connecting block. The end of the reciprocating screw away from the connecting block is fixed to the output end of the motor. The bottom of the motor is fixed to the top of the fixing block. The fixing block is fixed to the side wall of the base.

[0007] The scraper is slidably installed on the inner wall of the liquid storage tank. The reciprocating screw passes through the scraper and is threaded at the point of penetration. By starting the motor, the reciprocating screw is rotated, which causes the scraper to move against the surface of the filter screen, thereby cleaning the impurities attached to the surface of the filter screen. The cleaned impurities fall into the collection box through the drain hole.

[0008] Preferably, a connecting pipe is fixed to the left side of the water pump, the connecting pipe passes through the right side of the base and communicates with the liquid storage tank, a water outlet pipe is fixed to the top of the water pump, a main pipe is fixed to the end of the water outlet pipe away from the water pump, the main pipe is fixed to the top of the support plate, multiple sets of equally spaced spray heads are fixed to the bottom of the main pipe, and a drain pipe is fixed to the bottom of the culture box.

[0009] Preferably, a drain hole is provided on the left side of the base, and a collection box is fixed on the left side of the base.

[0010] Preferably, the culture box is provided in three sets, and the three sets of culture boxes are fixed on the support plate at equal distances.

[0011] Preferably, the stirring mechanism includes a drive belt, one side of which is wound around a reciprocating lead screw, and the side of the drive belt away from the reciprocating lead screw is wound around the outer wall of a rotating rod, and the two ends of the rotating rod are rotatably mounted on the inner wall of a groove.

[0012] Preferably, a driven transmission belt is wound around the outer wall of the rotating rod, and the side of the driven transmission belt away from the rotating rod is wound around the outer wall of the rotating shaft. One end of the rotating shaft is rotatably mounted on the inner wall of the groove, and the other end of the rotating shaft is rotatably mounted on the inner wall of the liquid storage tank.

[0013] Preferably, the outer wall of the rotating shaft is fixed with multiple sets of equally spaced stirring rods. When the reciprocating screw rotates, the stirring rods can stir the nutrient solution in the storage tank through the cooperation of the active transmission belt, the rotating rod, the driven transmission belt, the rotating shaft and the stirring rods, thereby fully mixing the different nutrients in the nutrient solution and improving the effect on plant cultivation.

[0014] Preferably, the support plate is provided in two sets, and the two sets of support plates are arranged in a mirror image of the base. A method for hydroponics includes the following steps:

[0015] S1. When carrying out hydroponics, the cultured plants can be placed in a culture box and the culture solution can be poured into a storage tank.

[0016] S2. By starting the water pump, the nutrient solution in the storage tank can be drawn out through the connecting pipe. The nutrient solution can be sprayed out from the spray head through the outlet pipe, main pipe and spray head, so that the plants can be sprayed with nutrient solution for planting.

[0017] S3. When the nutrient solution is sprayed into the culture box at the highest point of the support plate, it can then flow through the drain pipe to the culture box on the next layer for cultivation, thus allowing multiple plants to be cultivated.

[0018] S4. After the nutrient solution passes through the culture box, it will eventually flow into the storage tank. The used nutrient solution can be filtered through the filter screen, leaving the impurities in the nutrient solution on the filter screen, and allowing the clean nutrient solution to flow into the storage tank for recycling.

[0019] S5. When the motor is started, the reciprocating screw can be rotated, which in turn can make the scraper move on the reciprocating screw, so that the scraper moves in contact with the surface of the filter screen, thereby cleaning the surface of the filter screen and allowing the cleaned impurities to fall into the collection box through the drain hole.

[0020] S6. When the reciprocating screw rotates, the active drive belt, rotating rod, driven drive belt, rotating shaft and stirring rod work together to stir the nutrient solution in the storage tank, thereby fully mixing the different nutrients in the nutrient solution.

[0021] Compared with existing technologies, this invention provides a soilless cultivation device and its soilless cultivation method, which have the following beneficial effects on plant cultivation:

[0022] 1. This hydroponic cultivation device and its hydroponic cultivation method, through the coordination of a water pump, connecting pipe, outlet pipe, main pipe and spray head, can spray nutrient solution onto the plants. Through the drainage pipe, the nutrient solution in the cultivation box can flow to the next layer of cultivation box for cultivation, thus allowing multiple plants to be cultivated. Through the filter screen, impurities in the used nutrient solution can be filtered, and the filtered nutrient solution flows to the bottom of the filter screen for recycling. Thus, this method is not only highly efficient, but also reduces the labor force of workers.

[0023] 2. The soilless cultivation device and its soilless cultivation method involve starting a motor to rotate a reciprocating screw, which in turn causes a scraper to move against the surface of the filter screen, thereby cleaning the impurities attached to the surface of the filter screen. The cleaned impurities fall into the collection box through the drain hole.

[0024] 3. The soilless cultivation device and its soilless cultivation method, when the reciprocating screw rotates, through the cooperation of the active transmission belt, rotating rod, driven transmission belt, rotating shaft and stirring rod, can make the stirring rod stir the nutrient solution in the storage tank, thereby fully mixing different nutrients in the nutrient solution, so as to improve the effect of plant cultivation.

A groove 17 is opened on the base 1, and a stirring mechanism 16 is set on the groove 17.

[0031] In an embodiment of the present invention, the cleaning mechanism 15 includes: a connecting block 151, which is fixed to the top of the base 1; a reciprocating screw 152 is rotatably mounted on the right side of the connecting block 151; the connecting block 151 supports the reciprocating screw 152; one end of the reciprocating screw 152 away from the connecting block 151 is fixed to the output end of the motor 153; starting the motor 153 rotates the reciprocating screw 152; the bottom of the motor 153 is fixed to the top of a fixing block 14; the fixing block 14 is fixed to the side wall of the base 1; the fixing block 14 supports the motor 153; and a scraper 155, which is slidably mounted on the inner wall of the liquid storage tank 2; the reciprocating screw 152 passes through the scraper 155, and the passage is threaded; the bottom of the scraper 155 is in contact with the top of the filter screen 3; and the scraper 155 cleans the liquid. Impurities on the filter screen 3 are scraped off. A connecting pipe 10 is fixed to the left side of the water pump 9. The connecting pipe 10 passes through the right side of the base 1 and connects to the liquid storage tank 2. A water outlet pipe 11 is fixed to the top of the water pump 9. A main pipe 12 is fixed to the end of the water outlet pipe 11 away from the water pump 9. The main pipe 12 is fixed to the top of the support plate 4. Multiple sets of equally spaced spray nozzles 13 are fixed to the bottom of the main pipe 12. Nutrient solution can be sprayed onto the plants for cultivation by setting the spray nozzles 13. A drain pipe 20 is fixed to the bottom of the cultivation box 6. Nutrient solution can be used to cultivate multiple sets of plants by the drain pipe 20. A drain hole 18 is opened on the left side of the base 1. Impurities attached to the filter screen 3 can be discharged through the drain hole 18. A collection box 19 is fixed to the left side of the base 1. Impurities discharged from the drain hole 18 can be collected by setting the collection box 19.

[0032] In an embodiment of the present invention, the stirring mechanism 16 includes an active drive belt 161 that passes through the top of the base 1. One side of the active drive belt 161 is wound around the reciprocating lead screw 152, and the side of the active drive belt 161 away from the reciprocating lead screw 152 is wound around the outer wall of the rotating rod 162. Both ends of the rotating rod 162 are rotatably mounted on the inner wall of the groove 17. A driven drive belt 163 is wound around the outer wall of the rotating rod 162, and the side of the driven drive belt 163 away from the rotating rod 162 is wound around the outer wall of the rotating shaft 164. One end of the rotating shaft 164 is rotatably mounted on the inner wall of the groove 17, and the other end of the rotating shaft 164 is rotatably mounted on the inner wall of the liquid storage tank 2.

The stirring rods 165 can stir the nutrient solution, which can fully mix different nutrients in the nutrient solution, resulting in better plant cultivation.

[0033] A hydroponics method, the usage of which includes the following steps:

[0034] S1. When carrying out hydroponics, the cultured plants can be placed in the culture box 6 and the culture solution can be poured into the storage tank 2.

[0035] S2. By starting the water pump 9, the connecting pipe 10 can draw out the nutrient solution in the storage tank 2. Through the outlet pipe 11, the main pipe 12 and the spray head 13, the nutrient solution can be sprayed out from the spray head 13, so that the plants can be sprayed with nutrient solution for planting.

[0036] S3. When the nutrient solution is sprayed into the culture box 6 at the highest point of the support plate 4, the nutrient solution in the culture box 6 can flow to the next layer of culture box 6 for cultivation through the drain pipe 20, so that multiple plants can be cultivated.

[0037] S4. After the nutrient solution passes through the culture box 6, it will eventually flow into the storage tank 2. The used nutrient solution can be filtered through the filter screen 3, so that the impurities in the nutrient solution remain on the filter screen 3, and the clean nutrient solution flows into the storage tank 2, which can then be recycled.

[0038] S5. When the motor 153 is started, the reciprocating screw 152 can be rotated, which in turn causes the scraper 155 to move on the reciprocating screw 152. The scraper 155 moves in contact with the surface of the filter screen 3, which can clean the surface of the filter screen 3 and prevent too many impurities from adhering to the filter screen 3, which could easily cause the filter screen 3 to be blocked and affect the filtration effect of the filter screen 3. The cleaned impurities fall into the collection box 19 through the drain hole 18.

[0039] S6. When the reciprocating screw 152 rotates, it can drive the active transmission belt 161 to rotate. The active transmission belt 161 drives the rotating rod 162 to rotate, which in turn drives the driven transmission belt 163 to rotate. The driven transmission belt 163 drives the rotating shaft 164 to rotate, which in turn drives the stirring rod 165 to rotate. This allows the different nutrients in the nutrient solution to be thoroughly mixed, resulting in better plant cultivation.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
