Description

Technical Field

[0001] This utility model relates to the field of paddy field fertilization, and in particular to a quantitative fertilizer spreading device for paddy field fertilization. Background Technology

[0002] Fertilization of dryland paddy fields refers to agricultural production activities in dryland farmland that lacks a stable irrigation source and relies on natural rainfall to meet water needs. It involves applying fertilizers according to the growth and development patterns of rice and the soil nutrient status. Through reasonable selection of fertilizer types, application time arrangements, and application methods, sufficient nutrients are provided for rice growth to ensure yield and quality. Compared with paddy field fertilization, dryland paddy field fertilization places more emphasis on the integration effect of fertilizers with the soil and the adaptability to limited water conditions.

[0003] A search revealed that CN211671320U discloses a rice paddy fertilization device, relating to the field of agricultural production equipment. Addressing the problems of low fertilization efficiency and hazards in current rice paddy fertilization operations, the following solution is proposed: The device includes a main frame. Bearing sleeves are symmetrically distributed and fixedly installed on one side of the inner wall of the main frame. A rotating shaft is rotatably installed at the center of the two bearing sleeves. Rollers are fixedly installed at both ends of the rotating shaft, and a main shaft pulley is fixedly installed in the middle of the rotating shaft. A belt is connected to the main shaft pulley. A first motor is located on one side of the main shaft pulley, and the first motor is fixedly connected to the main frame. A motor pulley is fixedly installed on the output end of the first motor, and the motor pulley is connected to the main shaft pulley via a belt. This utility model has a novel structure, is simple to operate, highly practical, and suitable for widespread application.

[0004] Currently, when fertilizing dryland paddy fields, backpack-type quantitative fertilizer spreaders or towed fertilizer spreaders are commonly used. Backpack-type quantitative fertilizer spreaders are difficult to meet the needs of large-area fertilization and have a slow fertilization speed. Towed fertilizer spreaders require tractor to pull them and cannot be used for fertilization after rice planting, reducing the flexibility of fertilization. Therefore, we propose a quantitative fertilizer spreading device for paddy field fertilization to solve the above problems. Utility Model Content

A material injection cover 13 is fixedly connected to the upper surface of the storage hopper 1. The material injection cover 13 is located above the crushing roller 802. The variable frequency motor 801 drives the crushing roller 802 to rotate, which can crush agglomerated fertilizer, improve the dispersibility and applicability of fertilizer. The bearing ring 803 ensures the stable rotation of the crushing roller 802. In addition, the material injection cover 13 is located above the crushing roller 802, which facilitates the entry of fertilizer into the crushing area.

[0023] In a further embodiment, a circular spreading mesh plate 12 arranged in a ring is fixedly embedded on the bottom surface of the fertilizer spreading cover 4, and each material-dispensing blade 11 is located below the circular spreading mesh plate 12. A PLC controller 15 is fixedly installed on one side of the filling cover 13, and a battery compartment 14 is fixedly installed on the upper surface of the storage hopper 1. The battery compartment 14 is electrically connected to the PLC controller 15 through wires. The circular spreading mesh plate 12 plays a role in dispersing fertilizer. The material-dispensing blade 11 can make the fertilizer evenly spread in the paddy field. The battery compartment 14 can provide power support for the entire device. The PLC controller 15 is used to control the operation of components such as the electric metering valve 5, the drive motor 7, and the frequency converter motor 801.

[0024] The working principle of this utility model is as follows: First, fertilizer is poured into the storage hopper 1 through the injection hood 13. Then, the variable frequency motor 801 drives the crushing roller 802 to rotate, which can crush the clumped fertilizer. Next, the fertilizer in the storage hopper 1 is discharged downward through the fertilizer spreading pipe 2 and quantitatively conveyed under the control of the electric quantitative valve 5. When the fertilizer enters the fertilizer spreading hood 4, the drive motor 7 drives the rotating shaft 10 and the material spreading blade 11 to rotate, which can spread the fertilizer evenly through the circular spreading net plate 12. In addition, the moving wheels 904 facilitate the movement of the device in the paddy field, improving the flexibility of fertilization in the paddy field.
