Description

Technical Field

[0001] The present invention relates to the technical field of agricultural seedling cultivation, and particularly to a seed hydroponic germination incubator for agricultural seedling cultivation. Background Art

[0002] Hydroponics is a new type of soilless cultivation method for plants, also known as nutrient solution cultivation. Its core is to directly immerse the roots of plants in the nutrient solution. This nutrient solution can replace the soil and provide growth factors such as water, nutrients, and oxygen to the plants, enabling the plants to grow normally. Plants can directly absorb nutrients and water in the nutrient solution through their roots. However, traditional hydroponic incubators usually have the following several problems:

[0003] First of all, whether hydroponic seeds can continue to be soaked in water after germination depends on the type of seeds and their adaptability to the hydroponic environment. Hydroponic seeds require light, but the intensity and duration of light need to be adjusted according to the type and growth stage of the plants. Most seeds do not need to continue to be soaked in water after germination, but should be transferred to an appropriate hydroponic environment to maintain suitable moisture and light conditions. However, this step usually requires the entire tray containing the seeds to be removed, then the germinated seeds are selected and placed in a new tray, while the ungerminated seeds are re-immersed in the nutrient solution for another round of cultivation and germination. But if all the seeds in the tray are directly removed, there are also ungerminated seeds among them. If directly all are transferred, it will cause those ungerminated seeds to also be transferred and mixed with the germinated seeds, and be exposed to the air together. In this way, only the germinated seeds in this batch can germinate and grow normally, while the ungerminated seeds cannot germinate and grow, thus reducing the germination rate of this batch of seeds.

[0004] Therefore, we have designed a seed hydroponic germination incubator for agricultural seedling cultivation. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that most seeds do not need to continue to be soaked in water after germination, but should be transferred to an appropriate hydroponic environment to maintain suitable moisture and light conditions. However, this step usually requires cumbersome procedures to transfer the germinated seeds. Secondly, there are also some ungerminated seeds among the seeds. If directly transferred, it will cause some ungerminated seeds to also be completely exposed to the air, thereby reducing the germination rate. A seed hydroponic germination incubator for agricultural seedling cultivation is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A seed hydroponic germination incubator for agricultural seedling cultivation, comprising an incubator body and multiple cultivation seeds placed therein. It is characterized in that a tray for receiving multiple cultivation seeds is provided inside the incubator body, an annular sliding frame is provided on the outer side wall of the tray, a floating plate is connected to the annular sliding frame through a connecting rod, a liquid supplement pipe for supplementing and replacing the culture solution into the incubator body is provided on the side wall of the incubator body, the liquid level of the culture solution in the incubator body is the liquid level line, and the floating plate floats on the liquid level line;

[0008] A screen cloth is provided on the tray and tightly covers the upper surface of the cultivation seeds. The four sides of the screen cloth are positioned by the clamping parts on the tray, and the clamping parts on the incubator body are connected with a pushing component. The length of the pushing component is the same as that of the connecting rod. The pushing component is located below the multiple cultivation seeds. When the screen cloth disengages from the clamping part, the pushing component is pushed upward.

[0009] Preferably, the clamping part includes a counterweight block. The counterweight block is arranged at the bottom of the tray, and the counterweight block drives the pushing component to lift through a traction rope.

[0010] Preferably, the clamping part further includes a pushing block. The pushing block is arranged inside the tray and is used for squeezing and positioning the counterweight block.

[0012] Preferably, the pushing component includes a plurality of lifting rods arranged in a circular pattern. The bottoms of the plurality of lifting rods are provided with a same bottom ring. The lifting rod includes a lifting rod and an arc-shaped bracket connected end to end.

[0013] Preferably, the clamping part further includes a slot. The slot is coaxially arranged with the hemispherical hole on the tray. The screen cloth covers the cultivation seeds and is connected to the cultivation seeds. The edge of the screen cloth is inserted into the slot.

[0014] Preferably, a first moving cavity is provided on the side wall of the slot, and a pressing block pushed by a return spring is arranged inside the first moving cavity. The end of the pressing block extends out of the first moving cavity under the action of the return spring, and the end of the pressing block abuts against the screen cloth inserted into the slot.

The traction rope passes through the first rope hole, the conversion cavity and the second rope hole, and the traction rope located in the conversion cavity is wound around the outer side wall of the rotating shaft.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, the length of the pushing component is the same as that of the connecting rod. Therefore, it can be ensured that during the process of lifting the pushing component, the cultivation seeds located above the pushing component can be pushed to rise together and just be located at the liquid level line position, that is, the cultivation seeds are located at the liquid level line position.

Specific implementation mode

[0030] Refer to Figures 1-8 , a seed hydroponic germination incubator for agricultural seedling cultivation, including an incubator body 1 and multiple cultivated seeds 10 placed in the incubator body 1. The incubator body 1 is filled with a culture solution, and the liquid level of the internal culture solution is at the liquid level line 5. At the same time, a liquid supplement pipe 2 for supplementing and replacing the culture solution in the incubator body 1 is provided on the incubator body 1, and the liquid level of the liquid supplement pipe 2 for supplementing and replacing the culture solution is the liquid level line 5. In this way, it can ensure timely supplementation of the culture solution in the incubator body 1. When it is necessary to replace the culture solution in the incubator body 1, the tray 4 needs to be fixed first, and then replaced. After the culture solution is replaced, the fixation of the tray 4 is released. This setting is to ensure that the liquid level of the culture solution in the incubator body 1 is always at the liquid level line 5 to ensure the stability of the tray 4 in the incubator body 1.

[0031] Among them, a tray 4 for receiving multiple cultivated seeds 10 is provided in the incubator body 1. The setting of the tray 4 is to provide the placement conditions for the hydroponic germination of the cultivated seeds 10, and at the same time to ensure that the tray 4 is always in the culture solution in the incubator body 1, providing nutrients and a germination environment for the cultivated seeds 10 on the tray 4.

[0032] Among them, a floating plate 7 is provided on the support plate 4 to drive the support plate 4 to float, and an annular slide 3 is provided on the outer wall of the support plate 4. The annular slide 3 is connected to the floating plate 7 by a connecting rod 6. Therefore, under the action of the floating plate 7, the floating plate 7 floats at the liquid level line 5 of the culture solution, and under the connection action of the connecting rod 6, the entire support plate 4 is completely submerged in the culture solution in the incubator body 1, and the submerged depth of the support plate 4 is the same as the length of the connecting rod 6. Therefore, it can be ensured that no matter how much culture solution is in the incubator body 1, the height from the support plate 4 to the liquid level line 5 is a constant value, that is, the support plate 4 is located below the liquid level line 5 and the depth is the length of the connecting rod 6.

[0033] The length of the pushing component is the same as that of the connecting rod 6, so it can be ensured that the pushing component can push the cultivated seeds 10 located above the pushing component to rise together during the lifting process and just be located at the liquid level line 5, that is, the cultivated seeds 10 are at the liquid level line 5, so the germinated cultivated seeds 10 are pushed out of the support plate 4 to reach the liquid level line 5, thereby changing the environment of the germinated cultivated seeds 10, and changing the environment filled with culture solution where the cultivated seeds 10 are originally located to a new environment with air above and culture solution below. This environment can better provide a growth environment for the germinated cultivated seeds 10. If the germinated cultivated seeds 10 are not separated from the environment filled with culture solution in time, it will lead to the problem of necrosis of the cultivated seeds 10. Let the germinated cultivated seeds 10 experience sunlight and air in time, so as to better carry out photosynthesis.

[0034] Reference Figure 2 and Figure 4 In this state, a hemispherical hole 12 is provided on the top of the support plate 4, and the cultivation seeds 10 are located in the hemispherical hole 12, which provides a germination space for the cultivation seeds 10, while also reducing the impact of the water flow caused by the rehydration operation of the rehydration tube 2 on the cultivation seeds 10.

[0035] The support plate 4 is provided with a pushing assembly for pushing the seed 10 to be vertically lifted, and a telescopic cavity 13 for guiding the pushing assembly is opened in a circumference in the hemispherical hole 12. Figure 5 Indicates that this state is the extended state of the pushing component, and the cultivation seed 10 is lifted vertically.

[0036] Reference Figure 8Status, the driving component includes a plurality of lifting rods 8 arranged in a circle. A bottom ring 9 is provided at the bottom of the plurality of lifting rods 8. The lifting rod 8 includes a lifting rod 81 and an arc-shaped bracket 82 connected end to end. The arc of the arc-shaped bracket 82 facing the cultivation species 10 is the hole arc of the hemispherical hole 12. Therefore, it is ensured that as the lifting rod 81 slides upward in the telescopic cavity 13, the cultivation species 10 placed in the hemispherical hole 12 is pushed out of the hemispherical hole 12 and can stably exist above the arc-shaped brackets 82 arranged in a circle, providing support for the hydroponic germination and growth of the cultivation species 10.

[0037] A screen cloth 11 covering the cultivation species 10 is provided on the support plate 4. The function of the screen cloth 11 is to block part of the light, avoid strong light directly irradiating the cultivation species 10, and affect the germination of the cultivation species 10.

[0038] A slot 14 coaxially arranged with the hemispherical hole 12 is opened on the support plate 4. The screen cloth 11 covers the cultivation species 10 and is connected to the cultivation species 10. This setting can transmit the germination status of the cultivation species 10 to the covered screen cloth 11 in a timely manner. It should be noted that as the cultivation species 10 germinates, the germinated cultivation species 10 expands in volume, so the screen cloth 11 originally covering the surface of the cultivation species 10 will be lifted. Therefore, the function of the screen cloth 11 is not only to provide a weak light environment for the germination of the cultivation species 10, but also to timely feedback the status of the cultivation species 10 below the screen cloth 11 to the screen cloth 11.

[0039] Refer to Figure 3 Status, the edge of the screen cloth 11 is inserted into the slot 14. Therefore, after the cultivation species 10 germinates and its volume increases, it will lift the screen cloth 11 originally covering the surface of the cultivation species 10, so that the screen cloth 11 originally inserted into the slot 14 is lifted and separated from the slot 14.

[0040] A first movable cavity 15 is opened on the side wall of the slot 14, and a pressing block 18 pushed by a return spring 27 is arranged in the first movable cavity 15. The end of the pressing block 18 extends out of the first movable cavity 15 under the action of the return spring 27, and the end of the pressing block 18 abuts against the screen cloth 11 inserted into the slot 14. This can ensure that after the edge of the screen cloth 11 is inserted into the slot 14, the pressing block 18 originally partially extending out of the first movable cavity 15 will be squeezed back into the first movable cavity 15 again;

[0041] The bottom of the pallet 4 is provided with a temporary storage cavity 26, and a second movable cavity 16 is provided on the side wall of the temporary storage cavity 26. A pushing block 19 is arranged in the second movable cavity 16. The second movable cavity 16 is connected to the first movable cavity 15 through a communication hole 17, and the communication hole 17 is filled with hydraulic oil. Therefore, when the pressing block 18 that originally partially protruded from the first movable cavity 15 is squeezed back into the first movable cavity 15, it will push the pushing block 19 by squeezing the hydraulic oil and squeeze the counterweight block 20 located in the temporary storage cavity 26.

[0042] Since a counterweight block 20 is arranged in the temporary storage cavity 26, rubber layers are provided on the opposite side walls of the counterweight block 20 and the pushing block 19. In this way, the extrusion force after the edge of the screen cloth 11 is inserted into the slot 14 will be transmitted to the side wall of the counterweight block 20 by the pushing block 19. Due to the existence of friction, the counterweight block 20 will not fall in the temporary storage cavity 26.

[0043] Refer to Figures 5-7 In the state, when the screen cloth 11 originally inserted into the slot 14 is lifted and separated from the slot 14, the pressing block 18 extends out of the first movable cavity 15 again under the action of the return spring 27, and then drives the pushing block 19 to move towards the inside of the second movable cavity 16, that is, releases the extrusion of the side wall of the counterweight block 20 by the pushing block 19. Therefore, the counterweight block 20 will fall under the action of no friction generated by the extrusion, and pull the traction rope 21.

[0044] A conversion cavity 24 is provided in the pallet 4. A rotating shaft 25 is arranged in the conversion cavity 24. First rope holes 22 and second rope holes 23 are respectively provided on the side wall of the conversion cavity 24. The same traction rope 21 is connected between the counterweight block 20 and the bottom ring 9. The traction rope 21 passes through the first rope hole 22, the conversion cavity 24 and the second rope hole 23. The traction rope 21 located in the conversion cavity 24 is wound around the outer side wall of the rotating shaft 25. In this way, when the counterweight block 20 falls, it will pull the traction rope 21, drive the bottom ring 9 to lift, and finally vertically lift the cultivated seeds 10 germinated in the hemispherical holes 12, so that the environment where the original cultivated seeds 10 are located, which is full of culture solution, is changed to a new environment with air above and culture solution below.

[0045] It should be noted that: this device can screen each individual cultivated seed 10, can distinguish each cultivated seed 10 placed on the top of the pallet 4, and lifting the germinated cultivated seeds 10 to the liquid level line 5 changes the environment where the germinated cultivated seeds 10 are located, while the non-germinated cultivated seeds 10 still soak in the culture solution, avoiding direct transfer of all of them, which will cause some non-germinated cultivated seeds 10 to be completely exposed to the air as well, thereby reducing the germination rate of the cultivated seeds 10.

[0046] The working principle of the present invention is as follows:

[0047] The breeding variety 10 to be cultivated is placed in the hemispherical hole 12 on the pallet 4. When it is necessary to replace the culture solution in the incubator body 1, the pallet 4 needs to be fixed first and then replaced. After the culture solution is replaced, the fixation of the pallet 4 is released. This setting is to ensure that the liquid level of the culture solution in the incubator body 1 is always at the liquid level line 5. To ensure the stability of the pallet 4 in the incubator body 1, then cover the breeding variety 10 with a gauze cloth 11 and connect it to the breeding variety 10. This setting can transmit the germination state of the breeding variety 10 to the covered gauze cloth 11 in a timely manner. The extrusion force after the edge of the gauze cloth 11 is inserted into the slot 14 is transmitted to the push block 19 to squeeze the side wall of the counterweight 20. Due to the existence of friction, the counterweight 20 will not fall in the temporary storage cavity 26;

[0048] When the breeding variety 10 germinates and its volume increases, it will push up the gauze cloth 11 originally covering the surface of the breeding variety 10, so that the gauze cloth 11 originally inserted into the slot 14 is pushed up and separated from the slot 14. The pressing block 18 extends out of the first movable cavity 15 again under the action of the return spring 27, and then drives the push block 19 to move into the second movable cavity 16, that is, releases the extrusion of the side wall of the counterweight 20 by the push block 19. Therefore, the counterweight 20 will fall under the action of the friction force generated by the extrusion, and pull the traction rope 21. After the counterweight 20 falls, it will pull the traction rope 21 to drive the bottom ring 9 to lift, and finally vertically lift the breeding variety 10 germinated in the hemispherical hole 12, changing the original environment filled with culture solution where the breeding variety 10 is located to a new environment with air above and culture solution below.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
