AI Technical Summary

Technical Problem

Existing mechanized fertilization equipment cannot flexibly adjust the sowing amount and fertilizer amount per single hole, and powdered fertilizer is prone to agglomeration, causing blockage of the feed port, affecting operation continuity. Fertilizer is also prone to volatilization or loss, resulting in uneven nutrition.

Method used

A device for synchronously spreading soil disease treatment agents and seed fertilizers has been designed, including a seed feeding component, a fertilizer injection component, an extrusion component and a dispersion component. The sowing spacing and fertilizer amount can be flexibly adjusted through a removable sealing plug, a turntable and an adjusting bolt. The plow bar mixing soil structure is combined to prevent fertilizer volatilization and loss.

Benefits of technology

It achieves precise control of sowing spacing and fertilizer amount, avoids fertilizer misplacement causing seedling burn or nutrient deficiency, improves operational adaptability and resource utilization, ensures immediate mixing of fertilizer and soil, and blocks the volatilization path of ammonia nitrogen.

Abstract

The invention discloses a device and a method for synchronously applying preparations and seed fertilizers for treating soil diseases, and relates to the technical field of seed fertilization. A supporting plate is fixed to the left side of the mounting frame, a connecting hole is formed in the edge of the left side of the supporting plate, a connecting shaft is fixedly and rotatably connected to the interior of the connecting hole, a scattering assembly is mounted on the lower side of the mounting frame, a fertilizer injection assembly is mounted on the upper side of the supporting plate, and a fertilizer discharging assembly is mounted on the lower side of the supporting plate; the extrusion assembly is installed on the rear side of the supporting plate and matched with the fertilizer discharging assembly, the fertilizer injection assembly is connected with the fertilizer discharging assembly, the connecting assembly is installed on the front side of the supporting plate and connected with the scattering assembly, and the left end of the connecting assembly is connected with the connecting shaft. The single-hole sowing amount, the fertilizing amount and the seed spacing can be adjusted according to requirements, and meanwhile fertilizer volatilization can be avoided.
