Description

Technical Field

[0001] The present invention relates to the field of plant cultivation equipment, in particular to a water-saving agricultural plant cultivation device. Background Art

[0002] With global climate change and continued population growth, water shortages are becoming increasingly severe, especially in agriculture, where irrigation water accounts for a significant portion of global freshwater use. Traditional agricultural irrigation methods, such as flooding, severely waste water resources, with most water lost through evaporation and seepage, leaving a relatively low percentage of it actually absorbed and utilized by plants. Furthermore, in arid or seasonally water-scarce regions, crop yields often decline or even fail due to water shortages. Efficient, water-saving irrigation and cultivation methods are urgently needed to alleviate water pressure and ensure stable agricultural production.

[0003] Traditional agricultural plant cultivation often uses flat, single-layer planting patterns. This method not only inefficiently utilizes land and makes large-scale cultivation difficult within limited spaces, but also easily blocks sunlight from one another, resulting in uneven light exposure. For some plants, insufficient light limits photosynthesis, hindering growth and development, and affecting fruit quality and yield. Furthermore, fixed planting layouts result in poor ventilation, which facilitates the growth and spread of pests and diseases, further threatening plant health.

[0004] Although there are some water-saving irrigation equipment on the market, such as drip irrigation and sprinkler systems, they only solve part of the problem of irrigation water waste and cannot comprehensively optimize the plant cultivation process from the aspects of overall planting mode, gas supply, and nutrient supply. Although some improved planting racks have tried to increase the number of planting layers, they have deficiencies in lighting uniformity, structural stability, and coordinated operation of supporting facilities. Equipment for carbon dioxide supply and nutrient supply are mostly independent entities and are not organically integrated with planting and irrigation systems. Overall, existing technologies are difficult to meet the needs of modern efficient, precise, and sustainable agricultural development for the coordinated operation of multiple functions of plant cultivation devices. There is an urgent need to develop a new device that can comprehensively improve plant cultivation effects. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example:

[0028] Please see the attached Figure 1 -Attached Figure 7 , the embodiment of the present invention provides a water-saving agricultural plant cultivation device, such as Figure 1As shown, it includes a base 1, which serves as the supporting foundation of the entire device. Its material is sturdy and durable, and can stably carry the various components above it. A pool 2 is fixedly installed on one side of the top of the base 1. The pool 2 is used to store clean water required for irrigation. Its volume is designed according to the actual planting scale and can meet the irrigation needs of a large number of plants. Vertical poles 3 are fixedly installed on both sides of the top of the pool 2. The vertical poles 3 play a key role in supporting and positioning, ensuring the stability of subsequent installed components. A hollow shaft 4 is movably installed in the middle of the inner end of the vertical pole 3. The hollow shaft 4 can rotate flexibly under the support of the vertical pole 3, and a number of air holes 5 are opened on its outer diameter. These air holes The hole 5 is used to discharge the subsequently introduced carbon dioxide gas, providing a more suitable growth environment for the plants. The outer diameters of both sides of the hollow shaft 4 are fixedly mounted with rotating wheel frames 6 through support frames. The support frames ensure the firmness of the connection between the rotating wheel frame 6 and the hollow shaft 4. The rotating wheel frame 6 can rotate synchronously with the rotation of the hollow shaft 4. The inner ends of the rotating wheel frames 6 are movably mounted with bearing mounting frames 7. The bearing mounting frames 7 make the planting platform 8 smoother and more stable during the rotation process through the internal bearing structure. The inner ends of the bearing mounting frames 7 are fixedly mounted with planting platforms 8. The planting platform 8 is used to place the planting trough 9 and is the main carrier for plant planting. Several planting troughs 9 are fixedly installed in the middle of the planting platform 8. The number and size of the planting troughs 9 are reasonably set according to the planting needs of different plants, which is convenient for the growth and management of plants. A DC motor 14 is fixedly installed on the other side of the top of the base 1. The DC motor 14 serves as the power source of the entire device and can provide stable and adjustable power output. A transmission shaft 15 is fixedly installed on the driving end of the DC motor 14. The transmission shaft 15 transmits the power of the DC motor 14 to each component that needs to rotate. A carbon dioxide storage tank 19 is fixedly installed on the side of the upper surface of the base 1 close to the DC motor 14 through a support rod. The carbon dioxide storage tank 19 is used It stores carbon dioxide gas and provides necessary conditions for the photosynthesis of plants. Its storage capacity can be supplemented according to the growth cycle and needs of the plants. The two sides of the inner top of the vertical pole 3 are fixedly mounted on the two ends of the drainage chamber 26. The drainage chamber 26 is used to store and distribute nutrient solution. A number of drainage grooves 27 are provided at the bottom of the drainage chamber 26. The drainage grooves 27 are used to guide the nutrient solution to be discharged downward. The inner top of the drainage groove 27 is movably installed with a short shaft 28. The short shaft 28 can rotate flexibly in the drainage groove 27. The bottom end of the short shaft 28 is fixedly installed with a cross brush plate 29. The cross brush plate 29 rotates at high speed driven by the short shaft 28 to break the nutrient solution into a gaseous fluid.

[0029] In this embodiment, the bottom end of the planting trough 9 is fixedly installed with a cross frame 10 through a support rod. The cross frame 10 provides an installation base for the absorbent cotton 11 and also plays a certain supporting role. The top of the cross frame 10 is provided with absorbent cotton 11. The absorbent cotton 11 has good water absorption. When the planting trough 9 passes over the pool 2, it can quickly absorb the clean water in the pool 2. A number of first seepage holes 12 are provided on the bottom wall of the planting trough 9. The first seepage holes 12 are used to discharge excess water in the planting trough 9 to avoid poor growth of plants due to water accumulation. A number of second seepage holes 13 are provided inside the cross frame 10. The second seepage holes 13 are used to allow the clean water absorbed by the absorbent cotton 11 to drip downward under the action of gravity, thereby realizing irrigation of the plants in the planting trough 9 below.

[0030] Specifically, the transmission shaft 15 is driven to rotate by the DC motor 14, and the rotation of the transmission shaft 15 drives the first driving wheel 16 to rotate. During the rotation of the first driving wheel 16, the first driven wheel 17 and the hollow rotating shaft 4 are driven to rotate through the transmission of the first transmission belt 18. The rotation of the hollow rotating shaft 4 will drive the rotating wheel frames 6 on both sides to rotate. During the rotation of the rotating wheel frames 6, all the planting troughs 9 are driven to perform circumferential motion around the hollow rotating shaft 4. When all the planting troughs 9 in one of the planting platforms 8 pass through the water pool 2, the absorbent cotton 11 under the planting troughs 9 will absorb the clean water in the water pool 2. The absorbent cotton 11 can absorb water quickly and in large quantities due to its special material and structure. As the rotating wheel frame 6 rotates, when the planting troughs 9 rotate out of the water pool 2, the clean water in the absorbent cotton 11 will drip downward through the second seepage hole 13 The water in the planting trough 9 is irrigated by the dripping clean water. The excess water is discharged from the planting trough 9 through the first seepage hole 12 and finally discharged into the pool 2, forming an efficient water circulation system. It not only saves water resources, but also avoids waterlogging and slow growth caused by excessive watering. The multi-layer rotary planting method is adopted, that is, multiple planting platforms 8 are distributed in multiple layers around the hollow rotating shaft 4, which can not only keep uniform lighting effect for all plants, because each planting trough 9 has the opportunity to fully receive light during the rotation process, but also increase the planting area. The multi-layer setting greatly improves the space utilization rate compared with the single-layer planting, thereby improving the planting efficiency.

[0031] Furthermore, a first driving wheel 16 is fixedly mounted on the outer diameter of one side of the transmission shaft 15, and the first driving wheel 16 can rotate synchronously with the transmission shaft 15. One end of the hollow rotating shaft 4 extends to the outside of the vertical pole 3 and is fixedly mounted with a first driven wheel 17. The first driven wheel 17 is fixedly connected to the hollow rotating shaft 4 to ensure that the two rotate synchronously. The outer diameters of the first driving wheel 16 and the first driven wheel 17 are connected by a first transmission belt 18. The first transmission belt 18 transmits the rotation of the first driving wheel 16 to the first driven wheel 17, thereby driving the hollow rotating shaft 4 to rotate.

[0032] Furthermore, a rubber piston 20 is fixedly mounted on the bottom end of the carbon dioxide storage tank 19. The rubber piston 20 can realize reciprocating motion of compression and release under the action of a cam 22 and a return spring 21. A return spring 21 is fixedly mounted inside the rubber piston 20. After the rubber piston 20 is compressed, the return spring 21 can restore the rubber piston 20 to its initial position. A cam 22 is fixedly mounted on the outer diameter of one side of the transmission shaft 15 near the bottom of the rubber piston 20. The cam 22 rotates with the transmission shaft 15, and its special contour shape can intermittently squeeze the rubber piston 20. An air inlet 23 is opened on one side of the top of the rubber piston 20, and the air inlet 23 is connected to the interior of the carbon dioxide storage tank 19. When the rubber piston 20 is released and the internal air pressure decreases, the one-way rubber valve 25 of the air inlet 23 is opened, and the carbon dioxide gas in the carbon dioxide storage tank 19 is sucked into the rubber piston 20. An exhaust pipe 24 is fixedly installed on the other side of the top of the rubber piston 20, and the end of the exhaust pipe 24 is movably installed on one end of the hollow rotating shaft 4. When the rubber piston 20 is compressed and the internal air pressure increases, the one-way rubber valve 25 in the exhaust pipe 24 opens, and the carbon dioxide gas is discharged into the interior of the hollow rotating shaft 4 through the exhaust pipe 24. One-way rubber valves 25 are fixedly installed inside the air inlet 23 and the exhaust pipe 24. The one-way rubber valves 25 ensure that the gas can only flow in the set direction to prevent gas backflow.

[0033] Specifically, when the transmission shaft 15 rotates, it also drives the cam 22 to rotate. During the rotation process, the cam 22 will intermittently squeeze the rubber piston 20, and cooperate with the action of the return spring 21 to make the rubber piston 20 continuously perform compression and release reciprocating movements. When the rubber piston 20 is released, the internal air pressure decreases, and the one-way rubber valve 25 of the air inlet 23 is opened. The carbon dioxide gas in the carbon dioxide storage tank 19 is sucked into the rubber piston 20. When the rubber piston 20 is compressed, the internal air pressure increases, and the one-way rubber valve 25 in the exhaust pipe 24 opens. The carbon dioxide gas is discharged into the hollow rotating shaft 4 through the exhaust pipe 24, and then discharged through the air vent 5. The cycle repeats. By increasing the carbon dioxide concentration around the plant, photosynthesis can be enhanced, the photosynthetic efficiency of the plant can be improved, and the growth and development of the plant can be promoted.

[0034] Furthermore, a rotating rod 30 is movably installed on the upper side of the interior of the discharge chamber 26. The rotating rod 30 can rotate in the discharge chamber 26 to transmit power. A plurality of driving bevel gears 31 are fixedly installed on the outer diameter of the rotating rod 30. The driving bevel gear 31 rotates synchronously with the rotating rod 30. A driven bevel gear 32 is fixedly installed on the top of the short shaft 28. The driven bevel gear 32 is fixedly connected to the short shaft 28 to ensure that the two rotate synchronously. The inner ends of the corresponding side driving bevel gear 31 and the driven bevel gear 32 are meshed and connected. Through this meshing transmission mode, the rotation of the rotating rod 30 is transmitted to the short shaft 28, thereby driving the cross brush plate 29 to rotate.

[0035] Furthermore, the end of the transmission shaft 15 extends to one side of the pool 2 and is fixedly installed with a second driving wheel 33. The second driving wheel 33 rotates synchronously with the transmission shaft 15. One end of the rotating rod 30 extends to the outside of the drainage chamber 26 and is fixedly installed with a second driven wheel 34. The second driven wheel 34 is fixedly connected to the rotating rod 30 to ensure that the two rotate synchronously. The outer diameters of the second driving wheel 33 and the second driven wheel 34 are connected by a second transmission belt 35. The second transmission belt 35 transmits the rotation of the second driving wheel 33 to the second driven wheel 34, thereby driving the rotating rod 30 to rotate.

[0036] Furthermore, a nutrient solution inlet pipe 36 is fixedly installed on the front side of the drainage chamber 26. The nutrient solution inlet pipe 36 is used to introduce external nutrient solution into the drainage chamber 26. Several branch pipes 37 are fixedly installed on the inner side of the nutrient solution inlet pipe 36, and the ends of the branch pipes 37 extend to the interior of the corresponding side drainage trough 27. The branch pipes 37 distribute the nutrient solution to each drainage trough 27 so that it can be sprayed later through the cross brush plate 29.

[0037] Specifically, when the transmission shaft 15 rotates, it will also drive the second driving wheel 33 to rotate, and through the transmission of the second transmission belt 35, drive the second driven wheel 34 and the rotating rod 30 to rotate. When the rotating rod 30 rotates, it will drive all the driving bevel gears 31 to rotate. The rotating driving bevel gear 31 drives all the driven bevel gears 32 and the short shaft 28 to rotate through meshing transmission, thereby driving all the cross brush plates 29 to rotate at high speed. At this time, the nutrient solution is introduced through the nutrient solution inlet pipe 36, and the nutrient solution is sent into each drainage trough 27 through the branch pipe 37. The high-speed rotating cross brush plate 29 is used to break up the nutrient solution into a gaseous fluid and spray it evenly downward to achieve nutritional supplementation for the plants. The high-speed rotating cross brush plate 29 can fully break up the nutrient solution and evenly distribute it in the form of tiny particles, thereby improving the plant's absorption efficiency of the nutrient solution and thereby improving the plant's growth efficiency.

[0038] Working principle: First, plants are planted in all the planting troughs 9 on the planting platform 8, and clean water required for irrigation is added to the pool 2. The amount of clean water is reasonably added according to the growth stage of the plant and the planting scale. Then the DC motor 14 is started, and the DC motor 14 starts to run. The transmission shaft 15 is driven by the DC motor 14 to rotate. The rotation of the transmission shaft 15 drives the first driving wheel 16 to rotate. During the rotation of the first driving wheel 16, the first driven wheel 17 and the hollow shaft 4 are driven by the first transmission belt 18. The rotation of the hollow shaft 4 will drive the rotating wheel frames 6 on both sides to rotate. During the rotation of the rotating wheel frame 6, all the planting troughs 9 are driven to perform circumferential motion around the hollow shaft 4. When all the planting troughs 9 in one of the planting platforms 8 are rotated, the first driven wheel 16 is rotated. When the trough 9 passes over the pool 2, the absorbent cotton 11 below the planting trough 9 will absorb the clean water in the pool 2. Due to its special material and structure, the absorbent cotton 11 can absorb water quickly and in large quantities. As the rotating wheel frame 6 rotates, when the planting trough 9 is rotated out of the pool 2, the clean water in the absorbent cotton 11 will drip downward through the second seepage hole 13. At this time, the next planting platform 8 is just below it, and the dripping clean water is used to irrigate the plants in the planting trough 9. As the rotating wheel frame 6 continues to rotate, all the plants in the planting troughs 9 will be irrigated, and the excess water will be discharged from the planting trough 9 through the first seepage hole 12 and finally discharged back into the pool 2, forming an efficient water circulation system, which not only saves water resources, but also avoids waterlogging and growth disasters caused by excessive watering. In order to solve the problems of slowness, a multi-layer rotary planting method is adopted, that is, multiple planting platforms 8 are distributed in multiple layers around the hollow rotating shaft 4, which can not only keep a uniform lighting effect for all plants, because during the rotation process, each planting trough 9 has the opportunity to fully receive light, but also increase the planting area. Through the multi-layer setting, the space utilization rate is greatly improved compared with the single-layer planting, thereby improving the planting efficiency. In addition, when the transmission shaft 15 rotates, it also drives the cam 22 to rotate. During the rotation process, the cam 22 will intermittently squeeze the rubber piston 20, and cooperate with the reset spring 21 to make the rubber piston 20 continuously perform compression and release reciprocating movements. When the rubber piston 20 is released, the internal air pressure is reduced, and the one-way rubber valve 25 of the air inlet 23 is opened, and carbon dioxide The carbon dioxide gas in the storage box 19 is sucked into the rubber piston 20. When the rubber piston 20 is compressed, the internal air pressure increases, and the one-way rubber valve 25 in the exhaust pipe 24 opens. The carbon dioxide gas is discharged into the hollow shaft 4 through the exhaust pipe 24 and then discharged through the air vent 5. The cycle repeats, and by increasing the carbon dioxide concentration around the plants, photosynthesis can be enhanced, the photosynthetic efficiency of the plants can be improved, the growth and development of the plants can be promoted, and the crop yield can be increased. In addition, when the transmission shaft 15 rotates, it also drives the second driving wheel 33 to rotate, and through the transmission of the second transmission belt 35, the second driven wheel 34 and the rotating rod 30 are driven to rotate. When the rotating rod 30 rotates, it drives all the driving bevel gears 31 to rotate. The rotating driving bevel gears 31 are driven by meshing.This drives all driven bevel gears 32 and short shaft 28 to rotate, thereby driving all cross brush plates 29 to rotate at high speed. At this time, nutrient solution is introduced through the nutrient solution inlet pipe 36 and sent to each drainage trough 27 through the branch pipe 37. The high-speed rotating cross brush plates 29 break the nutrient solution into a gaseous fluid and spray it evenly downward to achieve nutritional supplementation for the plants. The high-speed rotating cross brush plates 29 can fully break up the nutrient solution and evenly distribute it in the form of tiny particles, improving the plant's absorption efficiency of the nutrient solution and thus improving the plant's growth efficiency.
