Description

Technical Field

[0001] The present application relates to the technical field of soilless cultivation, and more specifically, to a soilless cultivation device. Background Art

[0002] As people's living standards improve, their requirements for diet are getting higher and higher. As a vegetable in life, lettuce is loved by more and more people, so the cultivation of lettuce is related to the yield of lettuce. Existing lettuce cultivation mostly uses soilless cultivation methods and uses nutrient solution for cultivation. Publication No. CN208242504U, a Chinese patent discloses a soilless cultivation device for lettuce. The related technology mentioned above has some shortcomings. During actual use, the position of the plant growth lamp is fixed and the height cannot be adjusted. However, as the lettuce continues to grow, its volume will increase, causing the lettuce to get closer and closer to the growth lamp. Therefore, the lettuce close to the growth lamp may block the light source and affect the normal photosynthesis of other lettuces. This situation may affect the normal growth of lettuce.

[0003] The document with prior art publication number CN 220987025 U provides a soilless cultivation device for lettuce. The device cooperates with an incubator, a planting plate, planting holes, a fixed plate, a movable plate, a plant growth lamp, a handwheel, a threaded rod, a threaded groove, an adjustment plate, a mounting groove, a worm gear, and a worm. By turning the handwheel, the height of the plant growth lamp can be adjusted to accommodate lettuces at different growth stages, so that all lettuces on the device can carry out normal photosynthesis and ensure the quality of the lettuce. In addition, the height adjustment of the plant growth lamp relies on the meshing transmission effect of the worm gear and the worm gear. The self-locking property of the worm gear and the worm gear can ensure the stability of the position of the plant growth lamp after height adjustment, which is conducive to the stable use of the device.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, the water in the incubator cannot flow, which will cause the nutrient solution to be unable to circulate. When the nutrient solution does not circulate for a long time, the roots of the plants may suffocate due to lack of oxygen, resulting in the plants being unable to breathe normally, thereby affecting the growth and health of the plants.

[0005] In view of this, we propose a soilless cultivation device. Utility Model Content

[0007] The purpose of this application is to provide a soilless cultivation device that solves the technical problems in the above-mentioned background technology, achieves the technical effect of increasing the flow of nutrient solution in the incubator, improving the oxygen content, avoiding hypoxia of plant roots, and ensuring the healthy growth of plants.

[0008] 2. Technical solution

[0009] The technical solution of the present application provides a soilless cultivation device, including: an incubator, wherein a plurality of second water-flipping plates are fixed at equal intervals in the incubator, a third water-flipping plate is fixed on one side of the second water-flipping plates, a circulation hole is reserved between the third water-flipping plate and the second water-flipping plates, a water outlet hole is reserved between the lower surface of the third water-flipping plate and the incubator, a first water-flipping plate higher than the second water-flipping plate is fixedly installed inside the incubator, a submersible pump is fixedly installed between the first water-flipping plate and the incubator, a planting trough is formed between adjacent second water-flipping plates, and connecting pipes are connected through both sides of the bottom of the incubator.

[0010] By adopting the above technical solution, plants are planted on the planting board, and sufficient nutrient solution is added to the incubator. Under the action of the connecting pipe, the liquid levels in the planting troughs on the left and right sides are made coplanar. The first water-turning plate is higher than the second water-turning plate to prevent the nutrient solution from directly turning over into the next planting trough through the first water-turning plate. After the submersible pump extracts the nutrient solution, the nutrient solution in the rightmost planting trough is made to flow into the next planting trough. Then, when the liquid level is higher than the next second water-turning plate, it flows into the circulation hole, flows into the bottom of the next planting trough through the outlet hole, and then turns over to the next planting trough through the top, and finally flows into the leftmost planting trough. The nutrient solution flows back to the rightmost planting trough with a submersible pump through the connecting pipe, thereby realizing circular water turning, increasing the contact between the nutrient solution and the air, increasing the dissolved oxygen content of the nutrient solution, and avoiding hypoxia of the plant roots.

[0011] As an optional solution of the technical solution of this application document, a solenoid valve is connected to one side of the incubator, a liquid level gauge placed in a planting trough is installed on the planting plate, and legs are fixed to the bottom of the incubator.

[0012] By adopting the above technical solution, one end of the solenoid valve is connected to the incubator, and the other end can be connected to the nutrient solution tank. The height of the nutrient solution in the incubator is monitored by a liquid level gauge. When the height is lower than the set water level, the solenoid valve opens, allowing the nutrient solution in the nutrient solution tank to flow into the incubator, thereby ensuring the water level of the nutrient solution in the incubator, and supporting the incubator through the legs to avoid the connecting pipe from being broken.

[0013] As an optional solution to the technical solution of this application document, the water outlet end of the submersible pump is connected through a U-shaped pipe, and the first water-turning plate is placed in the U-shaped mouth of the U-shaped pipe.

[0014] By adopting the above technical solution, the planting trough on the far right and the planting trough on the far left form a communicating vessel under the action of the connecting pipe, and the nutrient solution in the rightmost area is extracted by a submersible pump, so that the water level of the nutrient solution in the rightmost area drops, and the nutrient solution in the planting trough on the left is replenished through the connecting pipe. The extracted nutrient solution is discharged into the second planting trough on the right through the U-shaped pipe.

[0015] As an optional solution to the technical solution of this application document, a plurality of cultivation holes are provided on the planting board, wherein each of the planting grooves is provided with a plurality of cultivation holes, and a plurality of air holes are provided on the planting board.

[0016] By adopting the above technical solution, each cultivation hole is used to cultivate plants, and the roots are inserted into the corresponding planting grooves. At the same time, the gas flow of the nutrient solution in the incubator is increased through multiple air holes.

[0017] As an optional solution to the technical solution of this application document, a filter screen is installed at one end of the connecting pipe away from the submersible pump, and a handle is fixed on the filter screen.

[0018] By adopting the above technical solution, the planting trough on the far left is used as a return nutrient solution, and the fallen roots or debris can be intercepted by the filter plate to prevent the debris from flowing back into the planting trough on the far right and causing clogging of the submersible pump, and the filter plate can be easily removed and cleaned through the handle.

[0021] 1. The present application plants on a planting board and adds a sufficient amount of nutrient solution into the incubator. The liquid levels in the planting troughs on the left and right sides are made coplanar by the action of a connecting pipe. The first water-turning plate is higher than the second water-turning plate to prevent the nutrient solution from directly turning over into the next planting trough through the first water-turning plate. After the submersible pump extracts the nutrient solution, the nutrient solution in the rightmost planting trough is made to flow into the next planting trough. Then, when the liquid level is higher than the next second water-turning plate, it flows into the circulation hole, flows into the bottom of the next planting trough through the water outlet, and turns over to the next planting trough through the top, and finally flows into the leftmost planting trough. The nutrient solution flows back to the rightmost planting trough with a submersible pump through the connecting pipe, thereby realizing water circulation, increasing the contact between the nutrient solution and the air, increasing the dissolved oxygen content of the nutrient solution, and avoiding hypoxia of the plant roots.

[0027] The present application is further described in detail below with reference to the accompanying drawings.

[0028] A soilless cultivation device comprises: an incubator 1, wherein a plurality of second water-turning plates 4 are fixed at equal intervals in the incubator 1, a third water-turning plate 5 is fixed on one side of the second water-turning plates 4, a circulation hole 7 is reserved between the third water-turning plate 5 and the second water-turning plates 4, a water outlet hole 71 is reserved between the lower surface of the third water-turning plate 5 and the incubator 1, a first water-turning plate 3 higher than the second water-turning plate 4 is fixedly installed inside the incubator 1, a submersible pump 8 is fixedly installed between the first water-turning plate 3 and the incubator 1, a planting trough 6 is formed between adjacent second water-turning plates 4, and a connecting pipe 9 is connected through both sides of the bottom of the incubator 1.

[0029] Reference Figure 1-Figure 4 The plants are planted on the planting plate 2, and a sufficient amount of nutrient solution is added to the incubator 1. Under the action of the connecting pipe 9, the liquid levels in the planting troughs 6 on the left and right sides are made coplanar. The first water-turning plate 3 is higher than the second water-turning plate 4 to prevent the nutrient solution from directly turning over into the next planting trough 6 through the first water-turning plate 3. After the submersible pump 8 extracts the nutrient solution, the nutrient solution in the rightmost planting trough 6 is made to flow into the next planting trough 6. Then, when the liquid level is higher than the next second water-turning plate 4, it flows into the circulation hole 7, flows into the bottom of the next planting trough 6 through the outlet hole 71, and then turns over to the next planting trough 6 from the top, and finally flows into the leftmost planting trough 6. The nutrient solution flows back to the rightmost planting trough 6 with the submersible pump 8 through the connecting pipe 9, thereby realizing circular water turning, increasing the contact between the nutrient solution and the air, increasing the dissolved oxygen content of the nutrient solution, and avoiding hypoxia of the plant roots.

[0030] A solenoid valve 11 is connected to one side of the incubator 1 , a liquid level gauge 12 placed in the planting trough 6 is inserted into the planting plate 2 , and a support leg 13 is fixed to the bottom of the incubator 1 .

[0031] Reference Figure 1 and Figure 2 One end of the solenoid valve 11 is connected to the incubator 1, and the other end is connected to the nutrient solution tank. The height of the nutrient solution in the incubator 1 is monitored by the liquid level meter 12. When the height is lower than the set water level, the solenoid valve 11 is opened, allowing the nutrient solution in the nutrient solution tank to flow into the incubator 1, thereby ensuring the water level of the nutrient solution in the incubator 1, and supporting the incubator 1 through the support legs 13 to avoid the connecting pipe 9 from being broken.

[0032] The water outlet end of the submersible pump 8 is connected through a U-shaped pipe 10 , and the first water-turning plate 3 is placed in the U-shaped opening of the U-shaped pipe 10 .

[0033] Reference Figure 4 The planting trough 6 on the far right and the planting trough 6 on the far left form a communicating vessel under the action of the connecting pipe 9, and the nutrient solution in the far right is extracted by the submersible pump 8, so that the water level of the nutrient solution in the far right drops, and the nutrient solution in the planting trough 6 on the left is replenished through the connecting pipe 9, and the extracted nutrient solution is discharged into the second planting trough 6 on the right through the U-shaped tube 10.

[0034] The planting board 2 is provided with a plurality of cultivation holes 21 , wherein each planting groove 6 is provided with a plurality of cultivation holes 21 , and the planting board 2 is provided with a plurality of ventilation holes 22 .

[0035] Reference Figure 2 and Figure 4 Each cultivation hole 21 is used for cultivating plants, and the roots are inserted into the corresponding planting groove 6. At the same time, the gas flow of the nutrient solution in the incubator 1 is increased through the multiple air holes 22.

[0036] A filter screen plate 91 is installed at one end of the connecting pipe 9 away from the submersible pump 8 , and a handle 92 is fixed on the filter screen plate 91 .

[0037] Reference Figure 3 The planting trough 6 on the far left is used as a return nutrient solution. The fallen roots or debris can be intercepted by the filter plate 91 to prevent the debris from flowing back into the planting trough 6 on the far right and causing clogging of the submersible pump 8. The filter plate 91 can be removed and cleaned through the handle 92.

[0038] Working principle: Insert the plants into the cultivation holes 21 and place the roots in the planting troughs 6. At the same time, add a sufficient amount of nutrient solution into the incubator 1, and power on the submersible pump 8 to extract the nutrient solution in the rightmost planting trough 6. After the nutrient solution turns over the first water-turning plate 3, it is transported to the next planting trough 6 through the U-shaped tube 10. When the liquid level is higher than the next second water-turning plate 4, it flows into the circulation hole 7, and then flows into the bottom of the next planting trough 6 through the outlet hole 71, and then turns over to the next planting trough 6 from the top, and finally flows into the leftmost planting trough 6. The nutrient solution flows back to the rightmost planting trough 6 with the submersible pump 8 through the connecting pipe 9, thereby realizing circular water turning, increasing the contact between the nutrient solution and the air, increasing the dissolved oxygen content of the nutrient solution, and avoiding hypoxia of the plant roots. It is worth noting that the heights of the second water-turning plate 4 and the third water-turning plate 5 decrease from right to left to avoid reflux of the nutrient solution.
