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

Abstract

The invention discloses a fertilizer discharge device for a no-tillage drill and a fertilizer discharge device using the fertilizer discharge device, belonging to the field of agricultural machinery, including a fertilizer discharge box, a fertilizer discharge sheave, a short fertilizer discharge pipe and a fertilizer discharge chute. The fertilizer discharge sheave is located inside the fertilizer discharge box; the short fertilizer discharge pipe is fixedly installed at the outlet of the bottom of the fertilizer discharge box and communicates with the inside of the fertilizer discharge box, and the fertilizer discharge chute is composed of a chute The bottom plate is composed of chute side plates located on both sides of the chute bottom plate and having an angle of 90° with the chute bottom plate, and the short fertilizer discharge pipes are located on two surfaces of the chute bottom plate. The beneficial effects of the present invention are: by setting a row of fertilizer slideways under the short fertilizer discharge pipes, the fertilizer coming out of the short fertilizer discharge pipes will slide down slowly on the bottom plate of the chute, and the friction between the fertilizer and the surface of the bottom plate of the chute will To disperse the piled fertilizer to achieve uniform fertilizer discharge.

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...
