Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an intelligent fertilization device. Background Technology

[0002] Fertilization is a crucial part of agricultural production, playing a vital role in increasing crop yield, improving crop quality, and maintaining soil health. Traditionally, fertilizer is applied by spreading it across the entire field. However, for crops with wide plant spacing, this method may result in low fertilizer utilization. Therefore, hole-applying fertilization is now commonly used to improve fertilizer efficiency.

[0003] Currently, rotary fertilizer applicators are commonly used for fertilization. These applicators have evenly distributed fertilizer outlets (such as duckbill-type outlets) on the drum. As the drum rotates, fertilizer is discharged into the field at uniform intervals through these outlets, achieving targeted fertilization. While rotary fertilizer applicators can achieve targeted fertilization of crops, different crops typically have different plant spacings. The fixed fertilizer outlets and intervals of these applicators make them difficult to adjust, hindering their adaptability to different crops. Therefore, different applicators with varying intervals are required for targeted fertilization of different crops, increasing both purchase and operating costs.

[0004] Therefore, the existing method of using roller fertilizer applicators for fixed-point fertilization has the problem that the fertilizer outlet is fixed on the roller, making it difficult to adjust the fertilization interval. This makes it difficult for the existing roller fertilizer applicators to adapt to fixed-point fertilization of different crops, increasing the purchase and use costs. Utility Model Content

[0012] As a preferred scheme of the utility model, the discharging roller comprises a barrel and a discharging turntable, the discharging turntable is rotationally arranged in the barrel, and a plurality of material grooves are uniformly arranged on the circumferential side of the discharging turntable.

[0013] The upper end of the barrel is provided with a feeding port, and the lower end of the barrel is provided with a discharging port.
