Description

Technical Field

[0001] The present invention belongs to the technical field of rice seedling cultivation, and in particular relates to a device and a method for cultivating rice seedlings in dry land. Background Art

[0002] Rice is an important cereal crop belonging to the genus Oryza in the Poaceae family. It is an annual aquatic herb and one of the world's major food crops. It is also a staple food source for people in Asia and other regions. The dry rice seedling cultivation device is a special equipment or system used to cultivate rice seedlings in arid environments. It realizes standardized and mechanized dry rice seedling cultivation through structured design. Its core functions include bed soil treatment, sowing, temperature control and moisture retention, and seedling management, aiming to improve seedling quality and production efficiency.

[0003] Currently, in the dryland rice seedling cultivation process, existing seedling cultivation devices often require manual removal of the substrate and seeds from the device using tools such as shovels after the seedlings are grown. This operation method has obvious drawbacks: since it is difficult to precisely control the force and angle of manual shoveling, the removal process can easily cause mechanical damage to the seed roots, leading to root breakage and root hair loss, which in turn affects the survival rate and greening speed of the seedlings after transplanting. Summary of the Invention

[0004] In response to the problems in the related art, the present invention proposes a dry rice seedling cultivation device and a cultivation method to overcome the above-mentioned technical problems existing in the existing related art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a device for cultivating rice seedlings in dryland cultivation. The device has an exquisite design and a reasonable structure, and is intended to improve the cultivation efficiency and quality of rice seedlings in dryland cultivation. Specifically, it includes a cultivation box, which serves as the main structure of the entire device. A rotating part is rotatably installed inside the cultivation box. Two rotating parts are provided, and the two rotating parts are symmetrically distributed. Both of them are rotatably installed with connecting parts to ensure that the connecting parts can rotate flexibly with the rotating parts. Both connecting parts are provided with connecting holes, and the connecting holes are slidably connected to sliders. This design allows the sliders to slide smoothly in the connecting holes. The sliders are fixedly installed on the planting placement rack, thereby driving the planting placement rack to move accordingly.

[0007] The planting rack is equipped with several evenly distributed planting slots, providing ample growth space for rice seeds. Each planting slot is internally provided with a chute, which is slidably connected to a connecting block, allowing the connecting block to slide freely within the chute. The connecting block is fixedly mounted on a connecting plate, ensuring a stable connection between the connecting plate and the planting slots. The slider is provided with a threaded hole, which is threadedly connected to a threaded rod. By rotating the threaded rod, the position of the slider and the planting rack can be precisely controlled.

[0008] Furthermore, the connecting plate is provided with filter holes of moderate size, which can ensure water circulation and prevent matrix loss. The threaded rod is rotatably mounted on the connecting piece to ensure that the threaded rod can rotate stably. The interior of the planting trough is used to place the matrix and rice seeds, providing the necessary nutrition and support for rice growth. The diameter of the matrix is ​​larger than the diameter of the filter holes, which effectively prevents the matrix from leaking out of the filter holes. A spraying mechanism is provided inside the incubator, which is used to accurately spray the nutrient solution required for the rice seeds to meet the nutritional needs of rice during growth. The rotating member is fixedly mounted with the output end of the first motor, and the first motor is fixedly mounted on the incubator. The flexible rotation of the rotating member is achieved by the drive of the first motor.

[0009] Furthermore, the spraying mechanism includes a diverter plate disposed within the incubator, the diverter plate being fixedly mounted on the top of the incubator to ensure uniform distribution of the nutrient solution. A plurality of nozzles are fixedly connected to the diverter plate, and the nozzles are evenly distributed on the diverter plate to achieve omnidirectional spraying of the nutrient solution.

[0010] Furthermore, the diverter plate is fixedly connected to one end of a connecting pipe, and the other end of the connecting pipe is fixedly connected to the interior of the mixing barrel to ensure smooth circulation of the nutrient solution. The connecting pipe is provided with a pump body, which is driven by the pump body to realize automatic delivery of the nutrient solution.

[0011] Furthermore, the mixing barrel is fixedly mounted on the top of the incubator for easy operation and observation. A stirring rod is rotatably mounted inside the mixing barrel. The stirring rod is fixedly mounted to the output end of a second motor, which is fixedly mounted on the mixing barrel. The second motor is driven by the second motor to achieve flexible rotation of the stirring rod, thereby ensuring sufficient mixing of the nutrient solution.

[0012] Furthermore, a water collection box is movably installed at the bottom of the incubator to collect excess water and nutrient solution. A filter is movably installed inside the water collection box to effectively filter impurities and keep the water clean.

[0013] Furthermore, the incubator is fixedly equipped with a fluorescent lamp and a humidity sensor. The fluorescent lamp provides the necessary lighting conditions for rice growth, and the humidity sensor monitors the humidity inside the incubator in real time to ensure a stable rice growth environment. The incubator is also provided with a ventilation port with a removable filter, which ensures air circulation while preventing the entry of external impurities.

[0014] Furthermore, the incubator is rotatably mounted with a door for easy observation and operation by the operator. The door is provided with a transparent observation port for easy observation of the growth of the rice at any time, and preliminary judgment can be made without opening the door.

[0015] The present invention has the following beneficial effects:

[0016] 1. This device uses a first motor to drive a rotating member, which drives the planting rack in smooth motion. This ensures that the seeds and substrate within the planting troughs are evenly illuminated and ventilated, creating an ideal environment for rice growth. Furthermore, fluorescent lamps within the incubator provide additional lighting, a humidity sensor monitors humidity changes in real time, and ventilation ports facilitate air circulation, further stabilizing the incubation environment and improving the quality and survival rate of dry rice seedlings.

[0017] 2. The threaded connection between the threaded rod and the slider allows for quick disassembly and installation of the planter rack, facilitating maintenance and replacement of the planting units. The connecting plate moves within the chute via the connecting block, allowing for complete removal of the seeds and substrate after seedling cultivation, facilitating transplanting and improving efficiency. Furthermore, the water collection box can be removed for cleaning, and the filter can be individually disassembled for cleaning, further simplifying maintenance and management of the device.

[0018] 3. In the spraying mechanism, a second motor drives a stirring rod to thoroughly mix the nutrient solution. The pump pumps the nutrient solution to the manifold, where it is evenly sprayed into the planting trough area in atomized form by multiple nozzles, ensuring that the seeds and substrate receive a comprehensive and even supply of nutrients. Simultaneously, a water collection box collects excess nutrient solution and water, filtering it through a filter to prevent clogging and facilitate nutrient solution recycling, thereby improving resource utilization efficiency.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
