Description

Technical Field

[0001] The invention relates to the technical field of vegetable cultivation, and in particular to a device for rapidly growing lettuce cultivated in a microporous hard matrix. Background Art

[0002] At present, soilless cultivation is a common vegetable cultivation method, among which nutrient film technology is one of the soilless cultivation technologies. As for nutrient film technology, it is a hydroponic method of planting vegetables in a shallow layer of flowing nutrient solution. Usually, the vegetable roots are placed in a thin layer of nutrient solution for cultivation, and the nutrient solution in the storage tank is continuously or intermittently circulated by a water pump to the vegetable roots planted on the cultivation bed, so that part of the roots are immersed in the nutrient solution and part of the roots are exposed to the air.

[0003] Although the current soilless cultivation method based on nutrient film technology can immerse part of the vegetable root system in the nutrient solution and expose the other part to the air, which is convenient for the vegetable root system to absorb fertilizer and water while also facilitating the vegetable root system to absorb oxygen, the inventors found that the current soilless cultivation method based on nutrient film technology for vegetables still has some shortcomings in the actual cultivation process, specifically:

[0004] Taking lettuce planting as an example, usually, vegetables are planted in planting troughs on the cultivation bed, and the vegetable roots extend into the planting troughs. At the same time, a water pump is usually used to circulate nutrient solution into the planting troughs so that part of the vegetable roots are immersed in the flowing nutrient solution and the other part is exposed to the air in the planting troughs. However, when encountering a long-term power outage or a water pump failure, the nutrient solution is difficult to circulate continuously or intermittently to the vegetable roots, which can easily lead to insufficient nutrient absorption by the vegetable roots and cause the vegetables to wilt, thereby making the soilless cultivation method insufficient in its risk resistance to emergencies such as long-term power outages or water pump failures.

[0005] Therefore, how to improve the risk resistance of this soilless cultivation method in resisting sudden situations such as long-term power outages or water pump failures is an urgent problem that needs to be solved. Summary of the invention

[0006] The purpose of the present invention is to provide a microporous hard substrate lettuce rapid growth device to address the above-mentioned shortcomings of the current soilless cultivation method based on nutrient solution film technology in the vegetable cultivation process, so as to improve the risk resistance of the soilless cultivation method in resisting sudden situations such as long-term power outages or water pump failures.

[0007] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0008] A device for rapidly growing lettuce in microporous hard substrate cultivation, comprising a planting trough and a supporting assembly, wherein a cavity is formed in the planting trough, the supporting assembly is located in the planting trough, a solid substrate is placed on the supporting assembly, the solid substrate has water absorption capacity, a placing portion is provided on the planting trough, the placing portion corresponds to the solid substrate, the placing portion is located above the solid substrate, the placing portion is used to place vegetables and allow the roots of the vegetables to extend into the cavity, and after the vegetables are placed on the placing portion, the lower part of the vegetable roots can contact the upper surface of the solid substrate;

[0009] The microporous hard matrix lettuce rapid growth device also includes a conveying component, which is compatible with the planting trough and is used to convey nutrient solution to the cavity. When the conveying component conveys the nutrient solution to the cavity, the solid matrix in the cavity can contact and absorb the nutrient solution, and the liquid level of the nutrient solution is located below the upper surface of the solid matrix.

[0010] As a preferred technical solution of the present application, the position of the placement portion relative to the planting groove along its height direction is adjustable.

[0011] As a preferred technical solution of the present application, the placement portion is provided with a plurality of card blocks, and the plurality of card blocks are distributed along the height direction of the placement portion. A card slot is provided at a portion of the planting groove used to cooperate with the placement portion, and the card slot is adapted to the card block. When the card slot cooperates with different card blocks, the position of the placement portion relative to the planting groove along its height direction changes;

[0012] Alternatively, the placement portion is threadedly connected to the planting groove, and the placement portion is rotated relative to the planting groove so that the position of the placement portion relative to the planting groove along the height direction thereof is changed.

[0013] As a preferred technical solution of the present application, the supporting assembly includes a tray, on which a limiting groove is provided, the limiting groove is adapted to the solid matrix, and the limiting groove is used to place the solid matrix so that the solid matrix is ​​fixed relative to the limiting groove.

[0014] As a preferred technical solution of the present application, the supporting assembly further includes an impeller, a first support member and a second support member, wherein the impeller and the first support member are arranged on the tray, the second support member is arranged on the planting trough, and the second support member is sleeved on the first support member;

[0015] A slider rail structure and a spring are also provided between the first support member and the second support member. The spring is elastic, one end of the spring abuts against the first support member, and the other end abuts against the second support member;

[0016] The first support member can rotate relative to the second support member, and when the first support member rotates relative to the second support member, the slider and rail structure drives the first support member to move relative to the second support member along the vertical direction;

[0017] The support assembly has an initial state. When the support assembly is in the initial state, the upper surface of the solid substrate placed on the support assembly can contact the lower part of the root system of the vegetable placed in the placement part. The spring provides elastic force to keep the support assembly in the initial state when no external force acts.

[0018] When the conveying component conveys nutrient solution to the cavity, the nutrient solution flow can act on the impeller, causing the nutrient solution flow to impact the impeller, thereby rotating the impeller, rotating the first support member relative to the second support member, moving the first support member in a vertical downward direction relative to the second support member, and increasing the deformation of the spring.

[0019] As a preferred technical solution of the present application, the slider and slide rail structure includes a slider and a slide rail, and the slider is adapted to the slide rail;

[0020] The slider is located on the first support member, and the slide rail is located on the second support member; or, the slider is located on the second support member, and the slide rail is located on the first support member;

[0021] When the first support member rotates relative to the second support member, the sliding block slides relative to the sliding groove, so that the first support member moves along the vertical direction relative to the second support member.

[0022] As a preferred technical solution of the present application, the slide rail has a multi-turn spiral structure.

[0023] As a preferred technical solution of the present application, the first support member includes a first support member part and a first support member part two, the first support member part two is rotatably connected to the first support member part, the first support member is nested with the second support member through the first support member part, the first support member is connected to the spring through the first support member part two, and the rotation axis of the first support member part two when rotating with the first support member part is in the same direction as the center axis of the spring.

[0024] As a preferred technical solution of the present application, the support assembly further includes a shielding member, the shielding member is an annular opening structure, the shielding member is arranged on the planting groove, the shielding member is used to cooperate with the impeller and enable the impeller to form an exposed area and a shielding area, the exposed area corresponds to the opening on the shielding member, and the shielding area is shielded by the shielding member;

[0025] When the conveying component conveys the nutrient solution to the cavity, the nutrient solution flows in the cavity, which can push the exposed area of ​​the impeller to rotate the impeller.

[0026] As the priority technical solution of the present application, the conveying component includes a liquid storage tank, a water pump and a water supply pipe. The liquid storage tank is used to place nutrient solution. The planting trough includes a water inlet and a water outlet. One end of the water supply pipe is connected to the water pump, and the other end is connected to the water inlet. The water supply pipe is used to transfer the nutrient solution in the liquid storage tank to the cavity of the planting trough through the water supply pipe, so that the cavity forms a nutrient solution flow, and the nutrient solution flow flows into the liquid storage tank after flowing out of the water outlet.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the scheme of the present application, by providing a supporting component, a solid matrix and a placement portion, after the vegetables are placed on the placement portion, the roots of the vegetables can extend into the cavity, and the lower part of the roots of the vegetables can contact the upper surface of the solid matrix. When the conveying component is used to convey the nutrient solution to the cavity, the solid matrix in the cavity can contact and absorb the nutrient solution, and the nutrient solution can penetrate into the upper surface of the solid matrix. At the same time, the liquid level of the nutrient solution in the cavity can be located below the upper surface of the solid matrix. In this way, when the lower part of the root system of the vegetables contacts the upper surface of the solid matrix to absorb the nutrient solution, the roots of the vegetables can be prevented from being immersed in the nutrient solution, thereby facilitating the absorption of nutrient solution and oxygen by the roots of the output seedlings. At the same time, since the solid matrix is ​​located below the roots of the vegetables, the downward movement of the roots of the vegetables can be controlled. Its growth-inhibiting effect can prevent the roots of vegetables from growing too long, and can prevent most areas of the roots of vegetables from being immersed in the nutrient solution, thereby further preventing the roots of vegetables from absorbing insufficient oxygen in the later stages of growth; at the same time, in the event of a long power outage or a failure of a conveying component, it is difficult to continuously or intermittently convey the nutrient solution to the cavity. Since the solid matrix has the ability to absorb water, the roots of vegetables can continuously absorb the nutrient solution stored in the solid matrix, thereby extending the time for the roots of vegetables to absorb the nutrient solution in this emergency, thereby reducing the probability of insufficient nutrient absorption by the roots of vegetables and the probability of wilting of vegetables, thereby improving the risk resistance of vegetables to sudden situations such as long power outages or failure of conveying components in the soilless cultivation method based on nutrient solution film technology;

[0029] 2. Furthermore, by providing the card slot and the card block, when the card slot cooperates with different card blocks, the position of the placement portion relative to the planting groove along its height direction changes, thereby improving the convenience of adjusting the height of the placement portion; when the placement portion is threadedly connected to the placement groove, the convenience of adjusting the height of the placement portion can also be improved;

[0030] 3. Furthermore, by setting an impeller, when the conveying component conveys the nutrient solution to the cavity, the nutrient solution water flow can impact the impeller, causing the impeller to rotate, thereby causing the first support member to rotate relative to the second support member, thereby causing the first support member to move vertically downward relative to the second support member, thereby lowering the height of the tray, thereby lowering the height of the solid matrix placed on the tray. In this way, the liquid level of the nutrient solution conveyed to the cavity can be lowered. On the one hand, the distance between the liquid level of the nutrient solution and the root system of the vegetable can be further increased, further facilitating the absorption of oxygen by the root system of the vegetable. On the other hand, the volume of the solid matrix immersed in the nutrient solution is increased, which can improve the absorption effect of the solid matrix on the nutrient solution. On the other hand, on the basis of enabling the solid matrix to absorb a sufficient amount of nutrient solution, the amount of nutrient solution required to be supplied can be reduced.

[0031] At the same time, in the process that the first support member moves relative to the second support member to lower the height of the tray, the deformation of the spring gradually increases. When the conveying component stops supplying nutrient solution, the impeller is not impacted by the nutrient solution flow, so that the spring recovers its deformation, so that the supporting component gradually recovers to its initial state under the elastic force of the spring, thereby increasing the height of the solid matrix, so that the upper surface of the solid matrix is ​​closer to the vegetables, further facilitating the vegetable roots to contact the upper surface of the solid matrix, and facilitating the vegetable roots to absorb the nutrient solution on the solid matrix;

[0032] Furthermore, when the conveying component conveys the nutrient solution into the cavity, the nutrient solution water flow impacts the impeller to rotate the impeller, and the rotating impeller can stir the nutrient solution, so that the nutrients in the nutrient solution are distributed more evenly, thereby further improving the absorption effect of the nutrient solution by the vegetable roots, which is more conducive to the cultivation and growth of vegetables;

[0033] At the same time, when the solid matrix used is porous, as the vegetables grow, the roots of the vegetables may grow toward the holes of the solid matrix. In the present application, as the nutrient solution water flow impacts the impeller, the tray can rotate and the height of the tray can be lowered, so that the roots of the vegetables and the solid matrix can move relative to each other, thereby reducing the degree of involvement between the roots of the vegetables and the solid matrix. In this way, when the vegetables are removed from the microporous hard matrix rapid growth device for cultivating lettuce of the present application, the roots of the vegetables can be separated from the solid matrix, which improves the convenience of removing the vegetables from the device of the present application and also improves the stability of the solid matrix placed on the tray.

[0034] 4. Furthermore, by providing a slider and a slide rail, when the first support member rotates relative to the second support member, the slider slides relative to the slide rail, so that the first support member moves vertically relative to the second support member, thereby improving the convenience of changing the height of the first support member and the tray.

[0046] Embodiment 1: This embodiment provides a device for rapidly growing lettuce using a microporous hard substrate. Figure 1-Figure 5 As shown, it includes a planting trough 1 and a supporting component 2, wherein a cavity 3 is formed in the planting trough 1, the supporting component 2 is located in the planting trough 1, a solid matrix 4 is placed on the supporting component 2, the solid matrix 4 has water absorption capacity, a placing portion 5 is provided on the planting trough 1, the placing portion 5 corresponds to the solid matrix 4, the placing portion 5 is located above the solid matrix 4, the placing portion 5 is used to place vegetables and allow the roots of the vegetables to extend into the cavity 3, and after the vegetables are placed on the placing portion 5, the lower part of the vegetable root can contact the upper surface of the solid matrix 4;

[0047] The microporous hard matrix lettuce rapid growth device also includes a conveying component 6, which is adapted to the planting trough 1. The conveying component 6 is used to convey nutrient solution to the cavity 3. When the conveying component 6 conveys the nutrient solution to the cavity 3, the solid matrix 4 in the cavity 3 can contact and absorb the nutrient solution, and the liquid level of the nutrient solution is located below the upper surface of the solid matrix 4.

[0048] In the present application, by providing a supporting component 2, a solid matrix 4 and a placement portion 5, after the vegetables are placed on the placement portion 5, the roots of the vegetables can extend into the cavity 3, and the lower part of the roots of the vegetables can contact the upper surface of the solid matrix 4. When the conveying component 6 is used to convey the nutrient solution to the cavity 3, the solid matrix 4 in the cavity 3 can contact and absorb the nutrient solution, and the nutrient solution can penetrate into the upper surface of the solid matrix 4. At the same time, the liquid level of the nutrient solution in the cavity 3 can be located below the upper surface of the solid matrix 4. In this way, when the lower part of the root system of the vegetables contacts the upper surface of the solid matrix 4 to absorb the nutrient solution, the roots of the vegetables can be prevented from being immersed in the nutrient solution, thereby facilitating the absorption of nutrient solution and oxygen by the roots of the output seedlings. At the same time, since the solid matrix 4 is located below the roots of the vegetables, it can hinder the downward growth of the roots of the vegetables, thereby preventing the roots of the vegetables from growing too long, and preventing the vegetables from growing too long. Most of the root area is immersed in the nutrient solution, thereby further preventing the vegetables from having insufficient oxygen absorption by the roots in the later stages of their growth. At the same time, in the event of an emergency such as a long power outage or a failure of the conveying component 6, it is difficult to continuously or intermittently convey the nutrient solution to the cavity 3. Since the solid matrix 4 has the ability to absorb water, the vegetable roots can continue to absorb the nutrient solution stored in the solid matrix, thereby extending the time for the vegetable roots to absorb the nutrient solution in this emergency, thereby reducing the probability of insufficient nutrient absorption by the vegetable roots and the probability of vegetable wilting, thereby improving the risk resistance of vegetables to emergencies such as long power outages or failures of the conveying component 6 in a soilless cultivation method based on nutrient solution film technology. Furthermore, the solid matrix 4 used in the present application may be the patent number CN115281054A, and the invention name is a solid matrix in a method for preparing a solid matrix and its application.

[0049] As a preferred embodiment, on the basis of the above-mentioned embodiment, further, the position of the placement portion 5 relative to the planting groove 1 along its height direction is adjustable.

[0050] Furthermore, the position of the placement portion 5 relative to the planting trough 1 is adjustable along its height direction, so that after the vegetables are placed in the planting trough 1, the height of the vegetable roots can be adjusted to ensure that the lower part of the vegetable roots is in contact with the upper surface of the solid matrix 4, so as to cultivate vegetables of different sizes.

[0051] As a preferred embodiment, on the basis of the above-mentioned manner, further, the placement portion 5 is provided with a plurality of card blocks 7, and the plurality of card blocks 7 are distributed along the height direction of the placement portion 5, and a card slot 8 is provided at a portion of the planting trough 1 for cooperating with the placement portion 5, and the card slot 8 is adapted to the card block 7, and when the card slot 8 cooperates with different card blocks 7, the position of the placement portion 5 relative to the planting trough 1 along its height direction changes;

[0052] Alternatively, the placement portion 5 is threadedly connected to the planting groove 1, and the placement portion 5 is rotated relative to the planting groove 1 so that the position of the placement portion 5 relative to the planting groove 1 along its height direction changes.

[0053] Furthermore, by providing the card slot 8 and the card block 7, when the card slot 8 cooperates with different card blocks 7, the position of the placement portion 5 relative to the planting groove 1 along its height direction changes, thereby improving the convenience of adjusting the height of the placement portion 5; when the placement portion 5 is threadedly connected to the placement groove, the convenience of adjusting the height of the placement portion 5 can also be improved.

[0054] As a preferred embodiment, on the basis of the above-mentioned method, further, the supporting assembly 2 includes a tray 9, and a limiting groove 10 is provided on the tray 9, and the limiting groove 10 is adapted to the solid matrix 4, and the limiting groove 10 is used to place the solid matrix 4 so that the solid matrix 4 is fixed relative to the limiting groove 10.

[0055] Furthermore, by providing a tray 9 and providing a limiting groove 10 on the tray 9, when the solid matrix 4 is placed on the limiting groove 10, the solid matrix 4 can be fixed relative to the limiting groove 10, thereby improving the stability of the solid matrix 4 when placed on the supporting component 2.

[0056] Furthermore, the tray 9 is a hollow structure, so that the nutrient solution can penetrate through the tray 9 and penetrate into the solid matrix 4 .

[0057] Embodiment 2: Based on the technical solution of embodiment 1, further, see Figure 1-Figure 5 As shown, the supporting assembly 2 further includes an impeller 11, a first support member 12 and a second support member 13. The impeller 11 and the first support member 12 are arranged on the tray 9, the second support member 13 is arranged on the planting trough 1, and the second support member 13 is sleeved on the first support member 12;

[0058] A slider rail structure and a spring 14 are also provided between the first support member 12 and the second support member 13. The spring 14 is elastic, and one end of the spring 14 abuts against the first support member 12, and the other end abuts against the second support member 13.

[0059] The first support member 12 can rotate relative to the second support member 13. When the first support member 12 rotates relative to the second support member 13, the slider rail structure drives the first support member 12 to move relative to the second support member 13 along the vertical direction;

[0060] The support assembly 2 has an initial state. When the support assembly 2 is in the initial state, the upper surface of the solid substrate 4 placed on the support assembly 2 can contact the lower part of the root system of the vegetable placed in the placement part 5. The spring 14 provides elastic force to keep the support assembly 2 in the initial state when no external force is applied.

[0061] When the conveying component 6 conveys the nutrient solution to the cavity 3, the nutrient solution water flow can act on the impeller 11, causing the nutrient solution water flow to impact the impeller 11, so that the impeller 11 rotates, so that the first support member 12 rotates relative to the second support member 13, and the first support member 12 moves in a vertical downward direction relative to the second support member 13, and the deformation of the spring 14 increases.

[0062] Furthermore, by providing the impeller 11, when the conveying assembly 6 conveys the nutrient solution to the cavity 3, the nutrient solution water flow can impact the impeller 11, causing the impeller 11 to rotate, thereby causing the first support member 12 to rotate relative to the second support member 13, thereby causing the first support member 12 to move vertically downward relative to the second support member 13, thereby lowering the height of the tray 9, thereby lowering the height of the solid matrix 4 placed on the tray 9. In this way, the liquid level of the nutrient solution conveyed to the cavity 3 can be lowered. On the one hand, the distance between the liquid level of the nutrient solution and the root system of the vegetables can be further increased, further facilitating the absorption of oxygen by the root system of the vegetables. On the other hand, the volume of the solid matrix 4 immersed in the nutrient solution is increased, which can improve the absorption effect of the solid matrix 4 on the nutrient solution. On the other hand, on the basis of enabling the solid matrix 4 to absorb a sufficient amount of nutrient solution, the amount of nutrient solution required to be supplied can be reduced.

[0063] At the same time, in the process that the first support member 12 moves relative to the second support member 13 to lower the height of the tray 9, the deformation of the spring 14 gradually increases. When the conveying component 6 stops supplying the nutrient solution, the impeller 11 is not impacted by the nutrient solution flow, so that the spring 14 recovers its deformation, so that the supporting component 2 gradually recovers to the initial state under the elastic force of the spring 14, thereby increasing the height of the solid matrix 4, so that the upper surface of the solid matrix 4 is closer to the vegetables, further facilitating the vegetable roots to contact the upper surface of the solid matrix 4, and more conducive to the vegetable roots to absorb the nutrient solution on the solid matrix 4;

[0064] Furthermore, when the conveying assembly 6 conveys the nutrient solution into the cavity 3, the nutrient solution water flow impacts the impeller 11 to rotate the impeller 11, and the rotating impeller 11 can stir the nutrient solution, so that the nutrients in the nutrient solution are more evenly distributed, thereby further improving the absorption effect of the nutrient solution by the vegetable roots, which is more conducive to the cultivation and growth of vegetables;

[0065] At the same time, when the solid matrix 4 used is a porous structure, as the vegetables grow, the vegetable roots will grow towards the holes of the solid matrix 4. In the present application, as the nutrient solution water flow impacts the impeller 11, the tray 9 can rotate and the height of the tray 9 can be lowered, so as to facilitate the relative movement of the vegetable roots and the solid matrix 4, thereby reducing the degree of involvement between the vegetable roots and the solid matrix 4. In this way, when the vegetables are removed from the microporous hard matrix lettuce rapid growth device of the present application, it is convenient to separate the vegetable roots from the solid matrix 4, thereby improving the convenience of removing the vegetables from the device of the present application, and also improving the stability of the solid matrix 4 placed on the tray 9.

[0066] As a preferred embodiment, on the basis of the above-mentioned manner, further, the slider and slide rail structure includes a slider 15 and a slide rail 16, and the slider 15 is adapted to the slide rail 16;

[0067] The slider 15 is located on the first support member 12, and the slide rail 16 is located on the second support member 13; or, the slider 15 is located on the second support member 13, and the slide rail 16 is located on the first support member 12;

[0068] When the first support member 12 rotates relative to the second support member 13 , the slider 15 slides relative to the slide groove, so that the first support member 12 moves relative to the second support member 13 along the vertical direction.

[0069] Furthermore, by providing a slider 15 and a slide rail 16, when the first support member 12 rotates relative to the second support member 13, the slider 15 slides relative to the slide rail 16, so that the first support member 12 moves vertically relative to the second support member 13, thereby improving the convenience of changing the height of the first support member 12 and the tray 9.

[0070] Embodiment 3: Based on the technical solution of Embodiment 2, further, see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the slide rail 16 is a multi-turn spiral structure.

[0071] Furthermore, by making the slide rail 16 a multi-turn spiral structure, the difficulty of moving the first support member 12 relative to the second support member 13 in the vertical direction can be reduced, which is more conducive to the linkage between the rotation of the first support member 12 relative to the second support member 13 and the movement of the first support member 12 relative to the second support member 13 in the vertical direction.

[0072] As a preferred embodiment, on the basis of the above method, further, the first support member 12 includes a first support member portion 17 and a first support member portion 18, the first support member portion 18 is rotatably connected to the first support member portion 17, the first support member 12 is nested with the second support member 13 through the first support member portion 17, the first support member 12 is connected to the spring 14 through the first support member portion 18, and the rotation axis of the first support member portion 18 when rotating with the first support member portion 17 is in the same direction as the central axis direction of the spring 14.

[0073] Furthermore, by providing the first support member portion 17 and the first support member portion 2 18 , the stability of the spring 14 when connected to the first support member 12 and the second support member 13 can be improved during the rotation of the first support member 12 relative to the second support member 13 .

[0074] As a preferred embodiment, on the basis of the above-mentioned manner, further, the supporting assembly 2 further includes a shielding member 19, the shielding member 19 is an annular opening structure, the shielding member 19 is arranged on the planting trough 1, the shielding member 19 is used to cooperate with the impeller 11 and enable the impeller 11 to form an exposed area and a shielding area, the exposed area corresponds to the opening on the shielding member 19, and the shielding area is shielded by the shielding member 19;
