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, ...

Embodiment Construction

[0010] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A solid fertilizer quantitative fertilization device includes a fertilizer box 1 and an outer grooved wheel fertilizer discharger 2 fitted on the lower side of the fertilizer box 1, and is arranged on the lower side of the outer grooved wheel type fertilizer 2 relative to the outer grooved wheel Type fertilizer discharger 2 can move up and down the fertilizer pipe bender 5, and the upper and lower ends of the flexible fertilizer pipe 3 are respectively connected to the outer groove wheel type fertilizer discharger 2 and the fertilizer pipe bender 5. Fertilizer pipe 3 side positions can be shifted up and down to adjust the configuration fertilizer pipe forced bending stop bar 4.

[0011] When the operation is in use, when the fertilizer delivery pipe bender 5 moves upward, with the cooperation of the forced bending limit rod 4 of the fertilizer delivery p...
