Description

Technical Field

[0001] The invention relates to the technical field of agricultural seedling cultivation, and in particular to a seed hydroponic germination culture box for agricultural seedling cultivation. Background Art

[0002] Hydroponics is a new type of soilless plant cultivation method, also known as nutrient solution culture. Its core is to directly immerse the roots of plants in nutrient solution. This nutrient solution can replace soil and provide plants with water, nutrients, oxygen and other growth factors, so that plants can grow normally. Plants can directly absorb nutrients and water in the nutrient solution through their roots. However, traditional hydroponic incubators usually have the following problems: 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 need light, but the intensity and time of light need to be adjusted according to the type and growth stage of the plant. 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 tray containing the seeds to be removed as a whole, and then the germinated seeds are selected and placed in a new tray, while the seeds that have not yet germinated are re-immersed in the nutrient solution to cultivate the ungerminated seeds again. However, if all the seeds in the tray are directly removed, there are also ungerminated seeds in this part of the seeds. If all are transferred directly, the seeds that have not yet germinated will also be transferred, mixed with the germinated seeds, and exposed to the air together. In this way, the seeds that can germinate and grow normally are only the germinated seeds, while the ungerminated seeds cannot germinate and grow, thereby reducing the germination rate of this batch of seeds.

[0003] Therefore, we designed a seed hydroponic germination incubator for agricultural seedling cultivation. Summary of the invention

[0004] 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 a proper hydroponic environment to maintain suitable moisture and light conditions. However, this step usually requires cumbersome steps to transfer the germinated seeds. Secondly, there are also some ungerminated seeds among the seeds. If they are directly transferred, some of the seeds that have not yet germinated will also be completely exposed to the air, thereby reducing the germination rate. A seed hydroponic germination incubator for agricultural seedling cultivation is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A seed hydroponic germination incubator for agricultural seedling cultivation, comprising an incubator body and a plurality of cultivated seeds placed therein, characterized in that a support plate for receiving the plurality of cultivated seeds is provided in the incubator body, an annular slide is provided on the outer side wall of the support plate, the annular slide is connected to a floating plate via a connecting rod, a liquid replenishing pipe for replenishing and replacing a culture solution in 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 a liquid level line, and the floating plate floats on the liquid level line; The support plate is provided with a gauze cloth which is tightly covered on the upper surface of the cultivation seeds. The four sides of the gauze cloth are positioned by the clamping parts on the support plate, and the clamping parts on the incubator body are connected with a pushing component. The length of the pushing component is the same as the length of the connecting rod. The pushing component is located below the multiple cultivation seeds. When the gauze cloth is separated from the clamping part, the pushing component is pushed upward.

[0010] Preferably, the clamping portion further comprises a slot, and the slot is coaxially arranged on the support plate with the hemispherical hole, the gauze cloth covers the cultivation seeds and is connected to the cultivation seeds, and the edge of the gauze cloth is inserted into the slot.

[0011] Preferably, a first movable cavity is opened on the side wall of the slot, and a pressing block pushed by a return spring is arranged in the first movable cavity, the end of the pressing block extends out of the first movable cavity under the action of the return spring, and the end of the pressing block abuts against the mesh cloth inserted into the slot.

[0012] Preferably, a temporary storage cavity is formed at the bottom of the support plate, and a second active cavity is formed on the side wall of the temporary storage cavity.

[0015] The beneficial effects of the present invention are: 1. In the present invention, the length of the pushing component is the same as the length of the connecting rod, so it can be ensured that during the lifting process, the pushing component can push the cultivated seeds located above the pushing component to rise together and be exactly located at the liquid level line, that is, the cultivated seeds are at the liquid level line, thereby ensuring that the germinated cultivated seeds are pushed out of the support plate to reach the liquid level line, thereby changing the environment in which the germinated cultivated seeds are located.

DETAILED DESCRIPTION

[0019] Reference Figure 1-Figure 8 A seed hydroponic germination incubator for agricultural seedling cultivation comprises an incubator body 1 and a plurality of cultivated seeds 10 placed in the incubator body 1. The incubator body 1 is filled with a culture solution, wherein the liquid level of the culture solution inside is at a liquid level line 5. At the same time, a liquid replenishing tube 2 for replenishing and replacing the culture solution in the incubator body 1 is arranged on the incubator body 1. The liquid level of the culture solution replenished and replaced by the liquid replenishing tube 2 is the liquid level line 5, so that the culture solution in the incubator body 1 can be replenished in time. When the culture solution in the incubator body 1 needs to be replaced, the support plate 4 needs to be fixed first and then replaced. When the culture solution is replaced, the support plate 4 is unfixed. 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, in order to ensure the stability of the support plate 4 in the incubator body 1.

[0020] The incubator body 1 is provided with a support plate 4 for holding a plurality of cultivation seeds 10, and the support plate 4 is provided to provide the cultivation seeds 10 with placement conditions for hydroponic germination, and also to ensure that the support plate 4 is always in the culture solution in the incubator body 1, thereby providing nutrition and germination environment for the cultivation seeds 10 on the support plate 4.

[0021] Among them, a floating plate 7 for driving the supporting plate 4 to float is arranged on the supporting plate 4, and an annular slide 3 is arranged on the outer side wall of the supporting plate 4, and the annular slide 3 is connected to the floating plate 7 through 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 supporting plate 4 is completely submerged in the culture solution in the incubator body 1, and the submerged depth of the supporting plate 4 is the same as the length of the connecting rod 6. Therefore, it can be ensured that no matter how much or how little culture solution is in the incubator body 1, the height from the supporting plate 4 to the liquid level line 5 is a fixed value, that is, the supporting plate 4 is located below the liquid level line 5, and the depth is the length of the connecting rod 6; 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 it is ensured that 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, from the original environment filled with culture solution where the cultivated seeds 10 are 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 cause the cultivated seeds 10 to necrotize. The germinated cultivated seeds 10 can experience sunlight and air in time, so as to better carry out photosynthesis.

[0022] 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.

[0023] The support plate 4 is provided with a pushing assembly for pushing the seed 10 to be raised vertically, and a telescopic cavity 13 for guiding the pushing assembly is provided in a circumferential manner in the hemispherical hole 12. Figure 5 It is shown that this state is the extended state of the pushing component, and the cultivating seed 10 is lifted vertically.

[0024] Reference Figure 8 State, the pushing component includes a plurality of lifting rods 8 arranged in a circle, and the bottom of the plurality of lifting rods 8 is provided with the same bottom ring 9, and the lifting rods 8 include a lifting rod 81 and an arc-shaped bracket 82 connected end to end, wherein the arc of the arc-shaped bracket 82 toward the side of the cultivated seed 10 is the arc of the hemispherical hole 12, thereby ensuring that the cultivated seed 10 placed in the hemispherical hole 12 is pushed out of the hemispherical hole 12 as the lifting rod 81 slides upward in the telescopic cavity 13, and can stably exist above the arc-shaped bracket 82 arranged in a circle, and provide support for the hydroponic germination growth of the cultivated seed 10.

[0025] A gauze cloth 11 covering the cultivation seeds 10 is provided on the support plate 4 . The gauze cloth 11 blocks part of the light to prevent strong light from directly irradiating the cultivation seeds 10 and affecting the germination of the cultivation seeds 10 .

[0026] A slot 14 coaxially arranged with the hemispherical hole 12 is provided on the support plate 4, and the gauze cloth 11 covers the cultivation seeds 10 and is connected to the cultivation seeds 10. This arrangement can timely transmit the germination status of the cultivation seeds 10 to the covering gauze cloth 11. It should be noted that: as the cultivation seeds 10 germinate, the volume of the germinated cultivation seeds 10 expands and becomes larger, thereby lifting up the gauze cloth 11 originally covering the surface of the cultivation seeds 10. Therefore, the function of the gauze cloth 11 is not only to provide a weaker light environment for the germination of the cultivation seeds 10, but also to timely feedback the status of the cultivation seeds 10 under the gauze cloth 11 to the gauze cloth 11.

[0027] Reference Figure 3 State, the edge of the gauze cloth 11 is inserted into the slot 14, so after the cultivated seeds 10 germinate, the volume becomes larger, which will lift up the gauze cloth 11 originally covering the surface of the cultivated seeds 10, thereby lifting up the gauze cloth 11 originally inserted into the slot 14 and detaching from the slot 14.

[0028] A first movable cavity 15 is formed 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 gauze cloth 11 inserted into the slot 14, so that after the edge of the gauze cloth 11 is inserted into the slot 14, the pressing block 18 that originally partially extends out of the first movable cavity 15 will be squeezed back into the first movable cavity 15; A temporary storage cavity 26 is provided at the bottom of the support plate 4, and a second active cavity 16 is provided on the side wall of the temporary storage cavity 26. A pushing block 19 is provided in the second active cavity 16. The second active cavity 16 is connected to the first active cavity 15 through a connecting hole 17, and the connecting hole 17 is filled with oil. Therefore, when the pressing block 18 that originally partially extends out of the first active cavity 15 is squeezed into the first active cavity 15 again, the pushing block 19 is pushed by squeezing the oil and squeezes the counterweight block 20 located in the temporary storage cavity 26.

[0029] Since a counterweight block 20 is provided in the temporary storage cavity 26, a rubber layer is 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 gauze cloth 11 is inserted into the slot 14 will be transmitted to the pushing block 19 to squeeze the side wall of the counterweight block 20. Due to the existence of friction, the counterweight block 20 will not fall off in the temporary storage cavity 26.

[0030] Reference Figure 5-Figure 7 In this state, when the mesh cloth 11 originally inserted into the slot 14 is lifted up and detached from the slot 14, the pressing block 18 extends out of the first active cavity 15 again under the action of the return spring 27, thereby driving the pushing block 19 to move toward the second active cavity 16, that is, releasing the squeezing of the side wall of the counterweight block 20 by the pushing block 19. Therefore, the counterweight block 20 will fall without the friction generated by pushing, and pull the traction rope 21.

[0031] A conversion chamber 24 is provided in the support plate 4, and a rotating shaft 25 is provided in the conversion chamber 24. A first rope hole 22 and a second rope hole 23 are respectively provided on the side walls of the conversion chamber 24. The counterweight 20 and the bottom ring 9 are connected with the same traction rope 21, which passes through the first rope hole 22, the conversion chamber 24 and the second rope hole 23. The traction rope 21 located in the conversion chamber 24 is wrapped around the outer wall of the rotating shaft 25. In this way, after the counterweight 20 falls, the traction rope 21 will be pulled to lift the bottom ring 9, and finally the cultivated seeds 10 germinated in the hemispherical hole 12 will be lifted vertically, so that the environment filled with culture solution in which the cultivated seeds 10 were originally located is replaced by a new environment with air above and culture solution below.

[0032] It should be noted that the device is capable of screening each individual cultivated seed 10, and is capable of distinguishing each cultivated seed 10 placed on the top of the support plate 4, and lifting the germinated cultivated seeds 10 to the liquid level line 5 to change the environment of the germinated cultivated seeds 10, while the cultivated seeds 10 that have not yet germinated are still soaked in the culture solution, avoiding direct transfer of all of them, which will cause some of the cultivated seeds 10 that have not yet germinated to be completely exposed to the air, thereby reducing the germination rate of the cultivated seeds 10.

[0033] The working principle of the present invention is as follows: The cultivation seeds 10 to be cultivated are placed in the hemispherical holes 12 on the support plate 4. When the culture solution in the incubator body 1 needs to be replaced, the support plate 4 needs to be fixed first and then replaced. When the culture solution is replaced, the support plate 4 is unfixed. This setting is to ensure that the culture solution level in the incubator body 1 is always located at the liquid level line 5. In order to ensure the stability of the support plate 4 in the incubator body 1, the cultivation seeds 10 are then covered with a gauze cloth 11 and connected to the cultivation seeds 10. This setting can timely transmit the germination state of the cultivation seeds 10 to the covered gauze cloth 11. The extrusion force after the edge of the gauze cloth 11 is inserted into the slot 14 is transmitted to the pushing block 19 to squeeze the side wall of the counterweight block 20. Due to the existence of friction, the counterweight block 20 will not fall off in the temporary storage cavity 26. When the cultivation seeds 10 germinate, their volume increases and they will lift up the gauze cloth 11 originally covering the surface of the cultivation seeds 10, thereby lifting up the gauze cloth 11 originally inserted into the slot 14 and detaching from the slot 14. The pressing block 18 extends out of the first active cavity 15 again under the action of the reset spring 27, thereby driving the pushing block 19 to move toward the second active cavity 16, i.e., releasing the squeezing of the side wall of the counterweight block 20 by the pushing block 19. Therefore, the counterweight block 20 will fall without the friction generated by pushing, and pull the traction rope 21. After the counterweight block 20 falls, it will pull the traction rope 21, driving the bottom ring 9 to rise, and finally vertically lifting the cultivation seeds 10 germinated in the hemispherical hole 12, so that the environment filled with culture solution in which the cultivation seeds 10 were originally located is replaced by a new environment with air above and culture solution below.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
