Double-row fixed-quantity spiral fertilizer feeder

Abstract

The invention discloses a double-row fixed-quantity spiral fertilizer feeder. The double-row fixed-quantity spiral fertilizer feeder comprises a shell, a left fertilizer feeding interface, a right fertilizer feeding interface, a stirring shaft, a fertilizer feeding shaft, a middle partition assembly and a fertilizer distributor and is characterized in that the left fertilizer feeding interface isarranged on the left lateral plate of the shell, the right fertilizer feeding interface is arranged on the right lateral plate of the shell, the stirring shaft is horizontally inserted into the shell,the fertilizer feeding shaft horizontally penetrates the shell, the middle partition assembly is arranged in the middle of a shell accommodating cavity, the fertilizer distributor is arranged on thetop surface of the shell and located right above the middle partition assembly, one end of the stirring shaft penetrates the middle partition assembly, and two ends of the fertilizer feeding shaft penetrate the middle partition assembly. The double-row fixed-quantity spiral fertilizer feeder has the advantages that fertilizer feeding efficiency can be evidently increased and fixed-quantity fertilizing can be achieved by using left fixed-quantity spiral fertilizer feeding and right fixed-quantity spiral fertilizer feeding, fertilizer utilization rate is increased, double-row fertilizing is achieved, and the structure of the fertilizer feeder is simplified.

Description

technical field [0001] The invention belongs to the technical field of crop fertilization equipment, and in particular relates to a one-device double-row quantitative spiral fertilizer discharger. Background technique [0002] Fertilization is one of the important factors affecting crop yield. The rational application of chemical fertilizers in sufficient quantities is conducive to the healthy growth of crops, and achieves the purpose of saving fertilizers, increasing efficiency, stabilizing production and increasing income. my country's fertilizer production and fertilization volume rank first in the world, but there are problems such as non-concentrated fertilization, low fertilizer utilization rate, and environmental pollution. With the development of agricultural machinery level and national policy orientation, especially the "one control and two reduction" policy proposed by the Ministry of Agriculture pointed out that the amount of chemical fertilizer application shou...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the commonly used fertilizer discharge devices for seeders are external grooved wheel fertilizer discharge devices, which can only realize one device and one row, and there are problems such as inconvenient adjustment of fertilizer discharge amount, inconsistent fertilizer discharge amount in each row, and uneven fertilization amount.

The amount of fertilizer required by different crops is inconsistent, and a single fertilizer discharger cannot meet the amount of fertilizer required by different crops
