Description

Technical Field

[0001] This utility model relates to the field of rice cultivation technology, and in particular to a cultivation device for rice cultivation. Background Technology

[0002] Rice cultivation is a crucial foundational step in agricultural production. The robustness of rice seedlings directly determines the survival rate of subsequent transplanting and the final yield. With the development of modern agricultural technology, intensive cultivation equipment is gradually replacing traditional field seedling raising, becoming a key tool for improving cultivation efficiency.

[0003] However, existing rice cultivation equipment has the following prominent problems: First, the irrigation precision is insufficient. Traditional equipment mostly adopts flood irrigation or fixed-position drip irrigation mode, which cannot dynamically adjust irrigation parameters according to the growth stage of rice. During the seedling stage, due to the weak plant shape, fixed high-position drip irrigation is prone to lodging due to water flow impact. During the tillering stage, the water demand increases and the root system expands. Fixed low-position drip irrigation is prone to uneven nutrient distribution, and may even cause root waterlogging due to local water accumulation, affecting the uniformity of seedling growth. Second, there are defects in the recycling and utilization of water resources and nutrient solution. During the irrigation process, water and nutrient solution that are not absorbed are mostly discharged directly, which not only leads to the double waste of water resources and fertilizers, but may also cause environmental pollution due to residual pesticides and fertilizers seeping into the soil or water sources.

[0004] Therefore, a cultivation device for rice cultivation is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a rice cultivation device that can solve the following prominent problems of existing rice cultivation devices: First, the irrigation precision is insufficient. Traditional equipment mostly adopts flood irrigation or fixed-position drip irrigation mode, which cannot dynamically adjust irrigation parameters according to the growth stage of rice. During the seedling stage, due to the weak plant shape, fixed high-position drip irrigation is easily affected by water flow impact and lodging. During the tillering stage, the water demand increases and the root system expands. Fixed low-position drip irrigation is prone to uneven nutrient distribution and even root waterlogging due to local water accumulation, which affects the uniformity of seedling growth. Second, there are defects in the recycling and utilization of water resources and nutrient solution. During the irrigation process, the water and nutrient solution that are not absorbed are mostly discharged directly, which not only leads to the double waste of water resources and fertilizers, but may also cause environmental pollution problems due to residual pesticides and fertilizers seeping into the soil or water sources.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cultivation device for rice cultivation, comprising a cultivation box, wherein a recycling structure is provided at the bottom of the cultivation box, a cultivation structure is provided inside the cultivation box, and a drip irrigation component is provided at the top of the cultivation box;

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application sets up a cultivation structure and drip irrigation components. The cultivation structure is placed in the middle of the cultivation box, which not only provides a layered and breathable cultivation environment for rice growth, but also forms a water storage cavity on the bottom side of the cultivation box. The motor drives the lead screw to move the slider along the cavity rod, so that the irrigation frame is raised and lowered synchronously through the hanging sleeve. The height of the drip irrigation head can be adjusted according to different growth stages of rice, such as the seedling stage and the tillering stage. With the help of the metering pump, the irrigation volume is precisely controlled. The layered design of the cultivation structure enhances drainage and breathability, and avoids the problems of water flow impact and lodging in the seedling stage and uneven nutrient distribution and waterlogging in the tillering stage. This improves irrigation accuracy and ensures the uniformity of seedling growth.

[0017] 2. By setting up a recycling structure, this application can recycle the unabsorbed water and nutrient solution collected in the bottom water storage chamber inside the cultivation box. After processing and filtration, the water is pumped back to the irrigation rack for recycling, reducing the waste of water and fertilizer resources, and avoiding environmental pollution caused by the direct discharge of residual substances. This solves the defects of traditional equipment in recycling. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A rice cultivation device includes a cultivation box 1, a recycling structure 2 at the bottom of the cultivation box 1, a cultivation structure 4 inside the cultivation box 1, and a drip irrigation component 5 at the top of the cultivation box 1.

[0027] The drip irrigation assembly 5 includes a metering pump 501 bolted to the rear side of the cultivation box 1. The absorption end of the metering pump 501 is connected to the rear side of the recovery structure 2. The output end of the metering pump 501 is connected to a hose 502. Cavity rods 503 are welded to both sides of the cultivation box 1. A motor 504 is bolted to the top of the right cavity rod 503. A lead screw 505 is fixedly connected to the output end of the motor 504. The lead screw 505 is located inside the right cavity rod 503. A slider 506 is slidably connected inside the cavity rod 503. The right slider 506 is threaded to the outside of the lead screw 505. An irrigation rack 507 is provided on the top of the cultivation box 1. The top of the irrigation rack 507 is connected to the hose 502. A hanging sleeve 508 is welded to the inside of the slider 506. The bottom of the hanging sleeve 508 is bolted to the outside of the irrigation rack 507. A drip irrigation head 509 is connected to the bottom of the irrigation rack 507.

[0028] In this embodiment: by setting up a cultivation box 1, a recycling structure 2, a cultivation structure 4, and a drip irrigation component 5, rice is planted in the cultivation structure 4 inside the cultivation box 1. When the motor 504 drives the lead screw 505 to rotate, it drives the right slider 506 to slide vertically along the inside of the cavity rod 503, and at the same time drives the left slider 506 to move synchronously. The irrigation frame 507 is raised and lowered as a whole by the hanging sleeve 508, so that the height of the drip irrigation head 509 can be dynamically adjusted according to the growth stage of the rice. The metering pump 501 draws liquid (including fresh nutrient solution or recycled liquid) from the recycling structure 2, and delivers it to the irrigation frame 507 through the hose 502. Finally, the drip irrigation head 509 accurately drips the liquid onto the surface of the cultivation structure 4. The liquid that is not absorbed during the irrigation process seeps into the bottom of the cultivation box 1 through the cultivation structure 4, and is then discharged to the recycling structure 2 for collection and treatment before being resupplyed to the metering pump 501, forming a closed loop process of "irrigation-recycling-reuse". This not only meets the needs of different growth stages through adjustable drip irrigation, but also improves the resource utilization rate through the circulation system.

[0029] Specifically, such as Figure 4As shown, the recycling structure 2 includes a nutrient solution tank 201 located at the bottom of the cultivation box 1. The rear side of the nutrient solution tank 201 is connected to the absorption end of the metering pump 501, and the top of the nutrient solution tank 201 is connected to a filter box 202.

[0030] Specifically, such as Figure 4 As shown, the top of the nutrient solution tank 201 is connected to a drain valve 203, and the top of the drain valve 203 is connected to the bottom of the cultivation box 1.

[0031] Specifically, such as Figure 4 As shown, the nutrient solution tank 201 is equipped with a quartz sand filter layer 204 and an activated carbon filter layer 205, with the quartz sand filter layer 204 located on top of the activated carbon filter layer 205.

[0032] In this embodiment: by setting up the recycling structure 2, the unabsorbed water and nutrient solution collected on the bottom side of the cultivation box 1 flows into the filter box 202 at the top of the nutrient solution tank 201 through the drain valve 203. During filtration, the water first passes through the quartz sand filter layer 204 to intercept larger particles such as substrate debris and root residues, and then passes through the activated carbon filter layer 205 to adsorb small molecule residues (such as pesticide and fertilizer residues) to complete the purification. The purified liquid is stored in the nutrient solution tank 201 and is drawn back into the drip irrigation component 5 when the metering pump 501 is working, realizing the recycling of water resources and nutrient solution, which reduces waste and avoids pollution.

[0033] Specifically, such as Figure 5 As shown, the cultivation structure 4 includes a partition mesh plate 401 welded to the middle of the inside of the cultivation box 1. The top of the partition mesh plate 401 is covered with a ceramsite layer 402, and the thickness of the ceramsite layer 402 is 5-8cm.

[0034] Specifically, such as Figure 5 As shown, a nutrient soil layer 403 is laid on top of the expanded clay layer 402. The thickness of the nutrient soil layer 403 is 10-15cm. A rice husk covering layer 404 is laid on top of the nutrient soil layer 403.

[0035] In this embodiment: by setting up the cultivation structure 4, the cultivation box 1 is divided into upper and lower areas by the partition mesh 401. The top is used as the cultivation area, and the bottom is reserved as a liquid storage space. The cultivation area is laid from bottom to top with a 5-8cm thick layer of expanded clay 402 (for air and drainage to avoid water accumulation), a 10-15cm thick layer of nutrient soil 403 (to provide nutrients to meet the needs of root growth), and a rice husk covering layer 404 (to retain moisture, prevent weeds, and reduce water evaporation). The layered structure not only ensures smooth root respiration but also allows for the rapid drainage of excess water. Combined with the drip irrigation component 5 for precise water supply, it effectively prevents waterlogging and provides a stable cultivation foundation for each growth stage of rice.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a transparent observation window 6 is embedded in the front side of the cultivation box 1, a temperature and humidity sensor 7 is installed on the rear side inside the cultivation box 1, ventilation fans 8 are embedded on both sides of the rear side inside the cultivation box 1, a water level sensor 9 is installed at the bottom of the rear side of the cultivation box 1, the sensing end of the water level sensor 9 is located on the bottom side inside the cultivation box 1, and a supplementary light 10 is installed at an angle on the rear side of the top of the cultivation box 1.

[0037] Specifically, such as Figure 1 As shown, an intelligent controller 3 is installed on the right side of the top of the nutrient solution tank 201. The intelligent controller 3 is electrically connected to the metering pump 501, the motor 504, the drain valve 203, the temperature and humidity sensor 7, the ventilation fan 8, the water level sensor 9, and the supplemental light 10.

[0038] In this embodiment: by setting up a transparent observation window 6, a temperature and humidity sensor 7, a ventilation fan 8, a water level sensor 9, a supplemental light 10, and an intelligent controller 3, the transparent observation window 6 facilitates direct observation of the rice growth status and substrate humidity. The temperature and humidity sensor 7 monitors the environmental parameters inside the cultivation box 1 in real time. If the temperature or humidity deviates from the suitable range, the intelligent controller 3 automatically starts the ventilation fan 8 to adjust the air circulation. The water level sensor 9 monitors the amount of liquid stored on the bottom side of the nutrient solution tank 201 and opens the drain valve 203 in time to discharge the liquid and avoid excessive accumulation. The supplemental light 10 automatically turns on when there is insufficient light (such as on cloudy days) to supplement the light. The intelligent controller 3 coordinates the metering pump 501, motor 504, and other components, and dynamically adjusts irrigation, light, ventilation, and other parameters according to the monitoring data to ensure that the rice is always in a suitable growth environment and improve the stability of cultivation.

[0039] Working principle: In the process of using the rice cultivation equipment, rice is first planted in the cultivation structure 4 inside the cultivation box 1. The partition mesh 401 divides the inside of the cultivation box 1 into upper and lower areas. The upper cultivation area is covered from bottom to top with a 5-8cm thick layer of expanded clay 402, a 10-15cm thick layer of nutrient soil 403, and a rice husk covering layer 404. The bottom is reserved for liquid storage. The layered structure ensures both root aeration and drainage, and also allows for the rapid removal of excess water. After the equipment is started, the intelligent controller 3 coordinates the work of each component: according to the rice growth stage... (For example, during the seedling and tillering stages), the motor 504 at the top of the right-side cavity rod 503 drives the lead screw 505 to rotate, causing the right-side slider 506 to slide along the cavity rod 503. At the same time, the left-side slider 506 moves synchronously. The irrigation frame 507 is raised and lowered by the hanging sleeve 508, realizing the dynamic adjustment of the height of the drip irrigation head 509. The metering pump 501 draws liquid (including fresh nutrient solution or recycled and purified liquid) from the nutrient solution tank 201, and delivers it to the irrigation frame 507 through the hose 502. Finally, the drip irrigation head 509 accurately drips the liquid onto the surface of the nutrient soil layer 403. With the flow control of the metering pump 501, water flow impact during the seedling stage is avoided to prevent lodging and uneven nutrient distribution during the tillering stage. Water and nutrient solution that are not absorbed during irrigation permeate through the expanded clay layer 402 and the separator mesh plate 401 to the bottom of the cultivation box 1. The intelligent controller 3 opens the drain valve 203 in a timely manner based on the monitoring data of the water level sensor 9, and discharges the waste liquid into the filter box 202 at the top of the nutrient solution tank 201. First, the quartz sand filter layer 204 at the top intercepts large particles of impurities such as substrate debris, and then the activated carbon filter layer 205 below adsorbs small molecule residual substances. The purified liquid is stored in the nutrient solution tank 201 for circulation by the metering pump 501, reducing resource waste and environmental pollution. Meanwhile, the transparent observation window 6 on the front of the cultivation box 1 allows for direct observation of the rice growth status. The temperature and humidity sensor 7 monitors the environment inside the cultivation box 1 in real time. If the parameters deviate from the suitable range, the intelligent controller 3 automatically starts the ventilation fan 8 to adjust the air circulation. When the light is insufficient, the supplementary light 10 set at the top is automatically turned on to supplement the light. Through the coordinated operation of various components, a stable and suitable growth environment is provided for the rice, ensuring the cultivation quality.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
