Description

Technical Field

[0001] The invention relates to the technical field of wheat cultivation, and in particular to an indoor cultivation device for wheat seedlings. Background Art

[0002] When growing wheat seedlings indoors, simple potting systems or static hydroponic systems are usually used. These systems rely on regular replacement of the culture solution to maintain appropriate nutrient levels and dissolved oxygen concentrations. However, this approach has several limitations, including but not limited to the inconvenience of frequent water changes, water waste, and possible mechanical damage to the root system.

[0003] When using flowing water for cultivation, care should be taken to control the flow rate of the water. It should not be too slow or too fast. Too slow a flow of water cannot effectively increase the dissolved oxygen and evenly distribute nutrients, while too fast a flow of water may damage the root system and affect the growth of wheat seedlings.

[0004] In order to take both of the above situations into consideration, the present invention provides a device for indoor cultivation of wheat seedlings. Summary of the invention

[0010] Optionally, the second nozzle has a built-in pressure reducing valve.

[0011] Optionally, an air intake grille and a filter cover are also included, and the air intake grille and the filter cover are respectively fixed to one side of the hydroponic frame close to the corresponding air inlet.

[0012] Optionally, a third fixed tube is further included, the third fixed tube is fixedly connected to the top of the hydroponic frame, the hydroponic frame is fixedly connected to a fixed frame, a corrugated tube is arranged in the third fixed tube, an L-shaped frame is fixedly connected to the end of the corrugated tube, the L-shaped frame is slidably connected to the fixed frame, a diversion groove is opened on the side of the L-shaped frame close to the first fixed tube, the fixed frame blocks the upper port of the diversion groove, and the first fixed tube blocks the lower port of the diversion groove.

[0013] Optionally, one side of the first cultivation frame and the second cultivation frame is rotatably connected with an expansion net.

[0014] Beneficial effects: The present invention realizes the circulation of water by setting a water pump, and slows down the speed of water spraying on the right side by means of multiple randomly distributed dispersion fins arranged inside the first nozzle. Thus, on the one hand, the high-speed water flow on the left side effectively increases the dissolved oxygen in the water and evenly distributes the nutrient solution, thereby improving the water quality and reducing the frequency of water changes. On the other hand, the slow water flow on the right side protects the wheat root system, avoids damaging the root system and affecting the growth of the wheat seedlings.

[0015] The present invention uses a stirring blade to break up the water output from the top of the water pipe at high speed, so that the water flow is scattered into the oxygenation chamber like a rotating water splash, and the fan rotates the external air into the oxygenation chamber. In this way, the rotating shaft of the water pump is used as a driving force to increase the contact area between water and air in the oxygenation chamber, so that the oxygen in the air can be more easily dissolved into the water, and the oxygen content in the flowing water is increased, thereby improving the cultivation effect of wheat.

[0016] The present invention arranges the grid plate so that the metabolic roots mixed in the water flow are filtered and retained in the oxygenation chamber, which on the one hand keeps the water clean and reduces the accumulation of harmful substances, and on the other hand prevents the accumulation of metabolic roots from clogging the water pump.

[0017] The present invention arranges a branch at the left part of the first fixed pipe, so that part of the water in the first fixed pipe flows into the second nozzle through the second fixed pipe, and then is slowly sprayed to the wheat roots on the left through the second nozzle, thereby ensuring the normal circulation of water flow and making the wheat on the left and right sides grow evenly.

[0018] When air enters the oxygenation chamber, the air intake grille and the filter cover play a dust-proof role, thereby ensuring the cleanliness of water quality.

[0019] The present invention utilizes the characteristics of thermal expansion and contraction of the bellows, and reduces the water pressure in the right part of the first fixed pipe by diverting and draining water at low temperatures, thereby slowing down the water flow speed to the right in the first fixed pipe; closes the diverting and draining channel at high temperatures to maintain the high-speed water flow speed to the right in the first fixed pipe, thereby achieving the goal of accelerating the flow rate at high temperatures to increase the dissolved oxygen content, and further reducing the flow rate at low temperatures to ensure the absorption of the root system.

[0020] The invention arranges the expansion net and arranges the second cultivation frame to be slidable, so that the ridge distance of wheat can be adjusted and the cultivation space can be expanded or reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0034] Embodiment 1: A device for indoor cultivation of wheat seedlings, such as Figure 1-Figure 5As shown, it includes a hydroponic frame 101, a support frame is fixedly connected to the bottom of the hydroponic frame 101, a first cultivation frame 102 is placed on the upper right side of the hydroponic frame 101, two second cultivation frames 103 are slidably connected to the left side of the first cultivation frame 102, and the adjacent second cultivation frames 103 are slidably connected, and water holes are opened at the bottom of the first cultivation frame 102 and the second cultivation frame 103, an oxygenation chamber is opened on the left side of the hydroponic frame 101, a water pipe 104 is fixedly connected to the left side of the hydroponic frame 101, and the upper end of the water pipe 104 is connected to the oxygenation chamber, and the bottom of the hydroponic frame 101 is fixedly connected to a first fixed pipe 105, and the first fixed pipe 105 is located between the support frame and the hydroponic frame 101, and the right side of the hydroponic frame 101 is fixedly connected to a first nozzle 106, and the right end of the first fixed pipe 105 is connected to the first nozzle 106, and the first nozzle 1 06 is provided with a plurality of randomly distributed dispersion fins for slowing down the outflow speed of water. A water pump 107 is fixedly connected to the bottom side of the left part of the hydroponic frame 101. The water pump 107 is communicated with the first fixed pipe 105. The rotating shaft 108 of the water pump 107 is rotatably connected to the hydroponic frame 101. The rotating shaft 108 penetrates upward into the water delivery pipe 104 and the oxygenation chamber. A spiral blade 109 is fixedly connected to the rotating shaft 108. The spiral blade 109 is located in the water delivery pipe 104. The spiral blade 109 is used to transport water upward along the water delivery pipe 104 into the oxygenation chamber. A stirring blade 110 is fixedly connected to one side of the rotating shaft 108 close to the top of the water delivery pipe 104. At least two air inlets are opened on the top of the left side of the hydroponic frame 101. A fan 111 is fixedly connected to one end of the rotating shaft 108 close to the front air inlet. The fan 111 is used to introduce external air into the oxygenation chamber. The hydroponic frame 101 A cover plate is provided on the top left side of the hydroponic frame 101, and a grid plate 112 is fixedly connected to one side of the hydroponic frame 101 close to the aeration chamber. The grid plate 112 is used to filter impurities such as root metabolites in the water.

[0035] First, spread a proper amount of loose soil rich in organic matter in the first cultivation frame 102 and the second cultivation frame 103, such as a mixture of peat soil, perlite and vermiculite, to provide good air permeability and water retention, and then evenly sow wheat seeds on the soil surface and cover with a thin layer of soil (about 0.5 cm). After sowing, water gently and allow excess water to flow into the hydroponic frame 101 through the water holes in the first cultivation frame 102 and the second cultivation frame 103 until sufficient water is accumulated in the hydroponic frame 101. After that, nutrient solution can be evenly sprinkled in the water.

[0036] During the cultivation process, if static water is used for cultivation, it is easy to cause root hypoxia, local nutrient excess or deficiency, salt accumulation, rot and other hazards, especially when the root system is dense. Therefore, in order to improve water quality and reduce the frequency of water changes, water flow is achieved through the following methods: The water pump 107 is started, so that the water in the left part of the hydroponic frame 101 is pumped into the first fixed pipe 105 at high speed, and then flows into the right part of the hydroponic frame 101 through the first nozzle 106, thereby realizing the circulation of water. In addition, a plurality of randomly distributed dispersion fins arranged inside the first nozzle 106 slow down the water flow speed. In this way, on the one hand, the high-speed water flow on the left side effectively increases the dissolved oxygen in the water and evenly distributes the nutrient solution. On the other hand, the slow water flow on the right side protects the wheat root system to avoid damaging the root system and affecting the growth of the wheat seedlings.

[0037] When the water pump 107 is started, the rotating shaft 108 of the water pump 107 drives the spiral blade 109 to rotate, so that a part of the water in the left part of the hydroponic frame 101 is transported upward to the oxygenation chamber through the water pipe 104. At the same time, the rotating shaft 108 drives the stirring blade 110 and the guide fan 111 to rotate. The stirring blade 110 breaks up the water output from the top of the water pipe 104 at high speed, so that the water flow is scattered into the oxygenation chamber like a rotating splash, and the guide fan 111 rotates the external air into the oxygenation chamber. In this way, the rotating shaft 108 of the water pump 107 is used as a driving force to increase the contact area between water and air in the oxygenation chamber, so that the oxygen in the air can be more easily dissolved into the water, and the oxygen content in the flowing water is increased, thereby improving the cultivation effect of wheat.

[0038] Metabolized wheat root waste and dead cells will be mixed into the water and flow with the water flow. The oxygenated water in the aeration chamber will flow back through the grid plate 112 into the left part of the hydroponic frame 101, and then flow into the left end of the first fixed pipe 105. In this way, the metabolic root substances mixed in the water flow will be filtered by the grid plate 112 and remain in the aeration chamber. On the one hand, the water quality is kept clean and the accumulation of harmful substances is reduced. On the other hand, the accumulation of metabolic root substances is prevented from clogging the water pump 107. The cover plate is opened regularly to clean the metabolic root substances in the aeration chamber.

[0039] like Figure 6 As shown, there are also two second fixed pipes 201, which are fixedly connected to the side of the first fixed pipe 105 close to the water pump 107, and two second nozzles 202 are fixedly connected to the side of the hydroponic frame 101 close to the second cultivation frame 103. The second nozzles 202 correspond to the second fixed pipes 201 one by one, and the second nozzles 202 are connected to the corresponding second fixed pipes 201. The second nozzles 202 have a built-in pressure reducing valve, so that water flows out slowly through the second nozzles 202.

[0040] As the wheat grows, its root system gradually develops. The water flowing out of the first nozzle 106 may be blocked by the root system and is difficult to flow to the left, which may cause uneven growth of the wheat near the left and right sides. Therefore, by setting a branch on the left side of the first fixed pipe 105, a part of the water in the first fixed pipe 105 flows into the second nozzle 202 through the second fixed pipe 201, and then is slowly sprayed to the wheat roots on the left through the second nozzle 202, thereby ensuring the normal circulation of water and, at the same time, making the wheat on the left and right sides grow evenly.

[0041] like Figure 7 As shown, it also includes an air intake grille 301 and a filter cover 302. The air intake grille 301 is fixedly connected to one side of the hydroponic frame 101 close to the rear air inlet, and the filter cover 302 is fixedly connected to one side of the hydroponic frame 101 close to the front air inlet.

[0042] When air enters the oxygenation chamber, the air intake grille 301 and the filter cover 302 are used to prevent dust to ensure the cleanliness of the water.

[0043] Embodiment 2: Based on embodiment 1, Figure 8-Figure 10 As shown, a third fixed tube 401 is also included, and the third fixed tube 401 is fixedly connected to the top of the hydroponic frame 101. A fixed frame 402 is fixedly connected to the lower left side of the hydroponic frame 101. A bellows 403 is arranged in the third fixed tube 401, and an L-shaped frame 404 is fixedly connected to the top of the bellows 403. The L-shaped frame 404 is slidably connected to the fixed frame 402. A diversion groove 405 is opened on the lower side of the L-shaped frame 404. The fixed frame 402 blocks the upper port of the diversion groove 405, and the first fixed tube 105 blocks the lower port of the diversion groove 405.

[0044] When the temperature is high, the movement of water molecules intensifies, making it easier for oxygen to escape from the water, resulting in a decrease in the dissolved oxygen content in the water. In order to ensure sufficient dissolved oxygen, the water flow rate may need to be increased to improve the dissolution and transmission efficiency of oxygen. On the contrary, when the temperature is low, the dissolved oxygen content in the water will increase. In order to avoid affecting the absorption and growth of the root system, the water flow rate should not be too fast. Therefore, in order to increase the dissolved oxygen content by speeding up the flow rate at high temperatures and reduce the flow rate at low temperatures to ensure root absorption, the specific operations are as follows: Since the bellows 403 has the characteristic of thermal expansion and contraction, when the temperature is low, such as in winter, the bellows 403 contracts and drives the L-shaped frame 404 to move downward, so that the diverter trough 405 moves downward to extend into the first fixed pipe 105. At this time, the upper port of the diverter trough 405 is no longer blocked by the fixed frame 402, and the lower port of the diverter trough 405 is no longer blocked by the first fixed pipe 105. In this way, a part of the water flow in the first fixed pipe 105 is discharged to the left part of the hydroponic frame 101 through the diverter trough 405. By diverting and draining water, the water pressure in the right part of the first fixed pipe 105 is reduced, thereby slowing down the water flow speed to the right in the first fixed pipe 105.

[0045] When the temperature is high, such as in summer, the bellows 403 expands and drives the L-shaped frame 404 to move upward, thereby causing the diverter trough 405 to move upward until the upper port of the diverter trough 405 is blocked by the fixed frame 402, and the lower port of the diverter trough 405 is blocked by the first fixed pipe 105, closing the diverter drainage channel and maintaining the high-speed water flow velocity flowing to the right in the first fixed pipe 105.

[0046] like Fig.11 As shown, the left sides of the first cultivation frame 102 and the second cultivation frame 103 are both rotatably connected with an expansion net 501 .

[0047] When it is necessary to expand the space to grow more wheat or increase the ridge distance of wheat, the second cultivation frame 103 can be slid to the left to open it, so that the distance between adjacent second cultivation frames 103 and the distance between the first cultivation frame 102 and the second cultivation frame 103 on the far right are increased. Then, the expansion net 501 can be rotated to the lower left to be laid down, and new wheat can be cultivated on the expansion net 501. When a small amount of wheat needs to be cultivated or the ridge distance of wheat needs to be reduced, the expansion net 501 can be rotated upward to be retracted, and the second cultivation frame 103 can be pushed to the right to reduce the space.

[0048] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
