Problems solved by technology

[0003] At present, most of the chemical fertilizers used as base fertilizers in my country are granular, and most of them use external groove wheel fertilizer dischargers and more univariate fertilization, that is, only control the rotation speed of the fertilizer discharge shaft to control the amount of fertilizer discharge. Compared with the double variable fertilizer spreader, the fertilizer discharge accuracy is poor. The scheduling is small, and at the same time, the pulsation will increase significantly during low-speed fertilizer discharge, and the uniformity of fertilizer discharge will be greatly reduced

Embodiment 1

[0019] refer to figure 1 It is a variable-variable fertilizer applicator fertilizing shaft speed and opening double adjusting device, comprising a frame, a speed adjusting mechanism, an opening adjusting mechanism and a fertilizer discharging device, characterized in that the speed adjusting mechanism is arranged on the right side of the fertilizer applicator frame, The opening adjustment mechanism is located on the left side of the fertilizer applicator frame, and the fertilizer discharge device is evenly distributed between the speed adjustment mechanism and the opening adjustment mechanism according to the specific farmland crop planting row spacing and the width of the variable fertilizer applicator. It includes a rotational speed motor 1, a rotational speed motor seat 19, a rotational speed sleeve 2, a rotational speed coupling 3, a support bearing 4, a rotational speed connector 5 and a spline 6. The above rotational speed motor 1 is arranged on the rotational speed m...

Embodiment 2

[0021] The difference between this example and Embodiment 1 is that the rotational speed coupling in the rotational speed adjusting mechanism can be a sleeve coupling or an elastic coupling.

Embodiment 3

[0023] The difference between this example and Embodiment 1 is that the rotational speed motor in the rotational speed adjusting mechanism may be a hydraulic motor or an electric motor.

Abstract

The invention relates to a rotary speed and opening degree double-adjustment device for a fertilizer discharging shaft of a variable fertilizer applicator. The rotary speed and opening degree double-adjustment device comprises a rack, a rotary speed adjusting mechanism, an opening degree adjusting mechanism and fertilizer discharging devices, and is characterized in that the rotary speed adjusting mechanism is arranged at the right side of the rack; the opening degree adjusting mechanism is arranged at the left side of the rack; and the fertilizer discharging devices are uniformly distributed between the rotary speed adjusting mechanism and the opening degree adjusting mechanism according to specific farmland plant planting line spacing and the width of the variable fertilizer applicator. The rotary speed adjusting mechanism is composed of a rotary speed motor, a rotary speed motor seat, a rotary speed sleeve, a rotary speed shaft coupler, a supporting bearing, a rotary speed connection piece and a spline; the opening degree adjusting mechanism is composed of an opening degree motor, an opening degree motor seat, an opening degree sleeve, an opening degree shaft coupler, an opening degree connection piece and a rotary bearing; and each fertilizer discharging device is composed of a fertilizer discharging box, a groove wheel, a fertilizer discharging stopping shaft, a clamping device and a follow-up baffle. The adjustment device can be used for adjusting the rotary speed and the opening degree of a fertilizer discharging main shaft at the same time so that the working efficiency is improved, and the influences in fertilization uniformity, caused by fertilizer discharging pulsatility in a fertilizer discharging process are reduced.

Description

technical field [0001] The invention relates to a double adjustment device for the rotational speed and opening of a fertilizer discharge shaft of a variable-variable fertilizer applicator, belonging to the field of agricultural machinery. Background technique [0002] At present, most of my country's farmland adopts extensive fertilization, and farmers mostly adopt the "average fertilization" method to fertilize the field according to their fertilization experience. This will cause imbalance of crop nutrient input ratio, low utilization rate of chemical fertilizer, and decrease of comparative benefit. Precise variable fertilization is an effective way to improve the quality of soil environment in my country, reduce soil and water pollution, and improve crop yield and quality. Variable fertilization is based on the agronomic requirements of different spatial units, using precise variable fertilization machinery to perform precise positioning and on-demand fertilization to m...
