Fertilizer discharger for no-tillage seed drill and fertilizer discharging device using fertilizer discharger

Abstract

The invention discloses a fertilizer discharger for a no-tillage seed drill and a fertilizer discharging device using the fertilizer discharger, and belongs to the field of agricultural machinery. Thefertilizer discharger comprises a fertilizer discharging box, a fertilizer discharging groove wheel, fertilizer discharging short pipes and fertilizer discharging slide grooves, wherein the fertilizer discharging groove wheel is positioned at the inner side of the fertilizer discharging box; each fertilizer discharging short pipe is fixedly arranged in a position of each bottom outlet of the fertilizer discharging box and communicates with the inside of the fertilizer discharging box; the fertilizer discharging slide groove consists of a slide groove bottom plate and slide groove side plates;the slide groove side plates are positioned at the two sides of the slide groove bottom plate and have an included angle being 90 degrees with the slide groove bottom plate; the fertilizer discharging short pipes are positioned on the two slide groove bottom plate surfaces. The fertilizer discharger has the beneficial effects that one fertilizer discharging slideway is arranged under each fertilizer discharging short pipe, so that the fertilizer discharged from the fertilizer discharging short pipes slowly slides down on the slide groove bottom plate; the piled fertilizer can be scattered through friction between the fertilizer and the slide groove bottom plate surfaces; the uniform fertilizer discharging is realized.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a fertilizer discharge device for a no-tillage drill and a fertilizer discharge device using the fertilizer discharge device. Background technique [0002] Efficient fertilization can increase the unit yield of crops and the comprehensive utilization rate of agricultural materials to achieve the purpose of increasing production and income; it can also adjust soil tissue composition, improve plant growth and nutrient absorption. The outer grooved wheel type fertilizer discharge device sets a fertilizer groove in the circumferential direction of the wheel, and the fertilizer is fed from the fertilizer tank into the fertilizer groove through the rotation of the groove wheel, and then falls from the fertilizer groove to the fertilizer guide device to apply the fertilizer to the sowing ground to realize fertilization. However, due to the arrangement of fertilizer troughs on the c...
