Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a taro planting machine and a taro planting method. Background Technology

[0002] Taro, a perennial herbaceous plant belonging to the genus *Colocasia* of the family Araceae, is native to tropical regions such as my country, India, and the Malay Peninsula. Compositionally, taro consists of leaves, petioles, tubers, flowers, and roots. The tubers can be used in soups, as a staple food, or for starch production. Historically, it has been considered an important food supplement or famine relief crop; the Yami people still rely on taro as a staple food. The petioles can be peeled and cooked or dried for storage. The entire plant is a common pig feed. The tubers are used medicinally to treat mastitis, canker sores, carbuncles, cervical lymph node tuberculosis, burns, and external bleeding. The leaves are used to treat urticaria and scabies. Taro is adaptable to various soil conditions and can grow in a variety of climates, but it thrives best in warm, humid environments.

[0003] Traditional taro cultivation relies heavily on manual labor, which is labor-intensive, inefficient, and difficult to scale up and standardize. While some machinery exists to assist in cultivation, it still has several shortcomings: First, frequent switching between various specialized equipment, such as trenchers, seeders, and fertilizer applicators, is cumbersome and extremely time-consuming. Each equipment change interrupts the planting process, severely impacting efficiency and extending the crop's growing cycle. Second, most existing equipment relies on manual operation, increasing both labor intensity and costs. Under such intense physical labor, farmers often struggle to maintain high efficiency, directly affecting the quality of planting and crop growth. Third, the lack of precise soil testing methods makes accurate fertilization and irrigation ratios difficult, leading to waste of fertilizer and water resources and potentially causing adverse effects on crop health, reduced yield, and lower quality due to excessive or insufficient fertilization or irrigation. Furthermore, this extensive farming method is often accompanied by the inefficient use of land resources, making it difficult to achieve sustainable agricultural development. Summary of the Invention

[0008] The fertilization mechanism is installed in the middle right side of the frame and includes a fertilizer box, an f-drive component, a b-screw, a push plate, a g-drive component, a mixing blade, an h-drive component, and a screw conveyor. The fertilizer box is fixedly connected to the frame and has an opening at its bottom.

The mixing blade is located in the mixing chamber, which has an opening at the bottom. The h-drive component is fixedly connected to the frame, and its output is fixedly connected to the screw conveyor, which is located below the opening at the bottom of the mixing chamber.

[0009] The sprinkler mechanism is installed in the middle of the frame, including a sprinkler section and a water tank installed at the rear of the frame. The sprinkler section includes a J drive component, a cam, a C connecting rod, a steering wheel, and a water channel fixing plate. The J drive component is fixedly connected to the frame, and its output shaft is fixedly connected to the cam. The steering wheel is located above the cam and is rotatably connected to the frame.

The water channel fixing plate is fixedly connected to the steering wheel, and the water tank is fixedly connected to the front of the middle of the frame.

[0010] The soil covering mechanism is installed in the middle of the right side of the frame and includes a K drive component, an A rack, a D connecting rod, a connecting part, and a soil covering plate. The K drive component is fixedly connected to the frame. The A rack is located below the K drive component and is fixedly connected to the frame.

[0011] Furthermore, the drive component consists of a rack and a motor gear set. The rack is fixedly connected to the frame, and the motor gear set meshes with the rack, driving the fixed frame to move up and down on the rack.

[0012] Furthermore, the driving component b is a motor, whose output shaft faces to the left rearward to tilt the trenching wheel to ensure that the trench has a certain width.

[0016] Furthermore, the fertilization mechanism also includes two guide plates fixedly connected to the frame. After the fertilizer falls from the bottom opening of the fertilizer box into the frame below the fertilizer box, it is pushed to the guide plate by the push plate, and the guide plate guides the fertilizer to the mixing chamber.

[0017] Furthermore, the sprinkler unit also includes a rotary device, which is located at the bottom of the sprinkler unit and rotatably connected to the frame. The rotary device drives the entire sprinkler unit to rotate.

[0018] Furthermore, the two soil-covering boards form an angle with the left side being larger than the right side to ensure the effectiveness of the soil covering.

[0019] A method for cultivating taro includes the following steps:

[0020] S1, the temperature and humidity sensor is driven downward by the a driving component to measure and record the temperature and humidity of the soil. After the measurement is completed, the temperature and humidity sensor moves upward back to its original position.

[0021] S2, the trenching wheel is driven by drive component b to rotate and perform trenching operations;

[0022] S3: First, the d drive unit drives the b turbine to rotate, which drives the support rod to rotate through the b connecting rod, so that the funnel is in the state below the slide. Then, the c drive unit drives the a turbine to rotate, which drives the push rod through the a connecting rod to push the taro falling from the storage box to the slide and into the funnel. Then, the d drive unit drives the b turbine to rotate, which drives the support rod to rotate through the b connecting rod until the support rod is in a horizontal state. Finally, the e drive unit drives the a lead screw to rotate, which pushes the b connecting rod outward through the connecting block, so that the front and rear halves of the funnel open and the taro falls into the groove.

[0023] S4. Based on the temperature and humidity measured in step S1, different fertilizers are placed into the fertilizer box. The f drive unit drives the b screw to reciprocate and push the falling fertilizer. The fertilizer falls into the mixing chamber through the guide plate. The g drive unit drives the mixing blade to rotate and mix the fertilizer. The mixed fertilizer falls from the opening below the mixing chamber into the channel where the screw conveyor is located. The h drive unit drives the screw conveyor to rotate and send the fertilizer to the trench.

[0024] S5 is driven by the j drive component to rotate the cam, which drives the steering wheel and water channel fixing plate to rotate through the c connecting rod to achieve the required angle for water spraying. The water spraying direction is adjusted left and right by the rotary device, and the water pump delivers the water in the water storage tank to the nozzle for water spraying.

[0025] S6, driven by the k drive component, moves the d connecting rod inward, causing the two covering plates to tighten their spacing for covering operations.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] This invention relates to a taro planting machine that significantly improves planting efficiency and precise control of crop growth conditions by integrating multiple functions. The machine's ingenious design combines multiple processes such as ditching, sowing, fertilizing, watering, and covering with soil into one, not only avoiding the tediousness and time waste caused by frequent equipment changes in traditional planting processes, but also greatly reducing farmers' labor intensity and costs through automated control. Simultaneously, by incorporating a detection mechanism that uses temperature and humidity sensors to monitor the soil environment, it ensures precise fertilizer and water ratios, thereby improving crop growth quality and yield.
