Quantitative fertilizer application device of solid-state fertilizer

Abstract

The invention provides a quantitative fertilizer application device of a solid-state fertilizer and belongs to agricultural machinery. A fertilizer conveying pipe bending device capable of moving up and down relative to an outer groove wheel type fertilizer discharging device is arranged at the side part below the outer groove wheel type fertilizer discharging device; the upper and lower end parts of a flexible fertilizer conveying pipe are respectively connected with the outer groove wheel type fertilizer discharging device and the fertilizer conveying pipe bending device; and a fertilizer conveying pipe forced bending limiting rod capable of being displaced and adjusted up and down is arranged at the side part of the flexible fertilizer conveying pipe. The device disclosed by the invention has the advantages of simple structure, low construction cost, high quantitative fertilizer application precision, fewer working faults, good reliability, long service life and wide applicable range, and quantitative fertilizer application adjusting operation is simple and convenient.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a solid chemical fertilizer quantitative fertilization device that can be assembled on various fertilization and seeding machines, soil preparation fertilization machines or intertillage fertilization machines. Background technique [0002] Quantitative fertilization of solid chemical fertilizers can make full and effective use of chemical fertilizers, thereby reducing the amount of chemical fertilizers used, which not only reduces the cost of agricultural production, but also helps to protect the soil and the environment. At present, mechanical solid fertilizer quantitative fertilizer applicators are mostly composed of outer groove wheel fertilizer discharger and valves of various structures. By automatically controlling the opening and closing of the valve, the quantitative discharge of solid fertilizer is realized and completed. The structure is complex, High manufacturing cost, ...

AI Technical Summary

Problems solved by technology

At present, mechanical solid fertilizer quantitative fertilizer applicators are mostly composed of outer groove wheel fertilizer discharger and valves of various structures. By automatically controlling the opening and closing of the valve, the quantitative discharge of solid fertilizer is realized and completed. The structure is complex, High manufacturing costs, many operational failures, poor reliability, and short service life are outstanding technical problems that urgently need to be overcome and resolved.

Also because of the above problems, the quantitative fertilizer applicator of this type of structure is affected and limited in production and application
