Fertilizing device for adjusting fertilizing depth and rotary cultivator

Abstract

The invention discloses a fertilizing device for adjusting fertilizing depth and a rotary cultivator. The fertilizing device comprises a fertilizing lifting mechanism and a fertilizing support, a fertilizing conveying mechanism is mounted on the fertilizing support which is rotatably connected with the fertilizing lifting mechanism, a middle supporting column is mounted in the middle of the fertilizing support, a left-side supporting column is mounted on the left side of the fertilizing support, a right-side supporting column is mounted on the right side of the fertilizing support, a left-sidebalance spring is connected between the left-side supporting column and the middle supporting column, and a right-side balance spring is connected between the right-side supporting column and the middle supporting column. The fertilizing device can conduct fertilizing during rotary cultivating, fertilizing depth can be adjusted, and the fertilizing device can maintain left-right balance to enablefertilizing depth on the left side and that on the right side to be uniform, thereby being good in fertilizing effect.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a fertilization device and a rotary tiller for adjusting fertilization depth. Background technique [0002] Rotary tiller is a kind of soil tillage machine driven by power. It has strong ability to cut soil and crush soil. It can achieve the effect of plowing and raking several times in one operation. With the continuous improvement of the level of agricultural science and technology, it has become a common method to complete the rotary tillage of farmland soil by rotary tiller. As everyone knows, the operating principle of the rotary tiller is to loosen and mash the mud (or soil clods) to achieve the purpose of cultivation when the rotary tiller shaft rotates. [0003] The existing rotary tiller is not equipped with a fertilizing device, and can only be used for rotary tillage of farmland soil, and cannot fertilize during rotary tillage. The function is single, the cost i...

AI Technical Summary

Problems solved by technology

[0003] Existing rotary tillers are not equipped with fertilization devices, and can only be used for rotary tillage of farmland soil, and cannot be fertilized during rotary tillage

Single function, high cost, small application range, poor economic benefit

In addition, the fertilization depth of the existing fertilization device cannot be adjusted. During the fertilization process in the uneven farmland soil, the fertilizer on one side will be scattered on the soil surface and cannot be buried in the soil, resulting in fertilizer loss and uneven fertilization.
