Problems solved by technology

[0004] Although there is a lot of research at home and abroad, there are also many mature products, but most of the large-scale fertilization machines cannot work in tea gardens with narrow row spacing due to their size and restrictions on the width of fertilization.
Although there are a few small-scale fertilization machines that can be used for fertilization in tea gardens, due to the relatively simple performance of the machines, high labor intensity, and low operating efficiency, fast and efficient fertilization cannot be achieved.

Embodiment Construction

[0021] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0022] Taking urea as the test fertilizer, walking speed, offset angle and leaf number as the influencing factors, and the distribution variation coefficient of the number of fertilizer particles in each collection box as the evaluation index of fertilization effect, a quadratic regression with three factors and three levels was used Combination design test method of cross rotation center, fertilization effect test is carried out on the tillage and fertilization test bench. Cultivation and fertilization test bench such as figure 1 As shown, the fertilizer granule collection box is as figure 2 shown. Among them, the three levels of walking speed are 0.4m / s, 0.6m / s, and 0.8m / s, the angle change levels of centrifugal disc blades are 0, 30, and 60, and the number of blades is adjusted to 2, 4, and 6 respectively.

Abstract

The invention discloses a method for optimizing working parameters of a centrifugal fertilizer spreading plate, and belongs to the field of agricultural machinery equipment. According to the method, the working parameters such as the travel speed, the centrifugal plate blade number, the centrifugal plate blade offset angle and the like of the centrifugal fertilizer spreading plate are optimized and combined, so that on one hand, the uniformity and stability of fertilizer spreading can be improved; and on the other hand, the fertilizer spreading cost is reduced, the fertilizer spreading efficiency is improved, the fertilizer spreading operation range is relatively wide, and the method can be applied to fertilizer spreading operation of any crop in tea trees, corns, apple trees, pear trees, wheat, peach trees and orange trees.

Description

technical field [0001] The invention belongs to the field of agricultural operation equipment, and in particular relates to the technology for optimizing the working parameters of a centrifugal fertilizer spreader. Background technique [0002] Field fertilization is one of the important operation methods in tea garden management. As an important tea garden fertilization method, fertilization machinery provides a guarantee for efficient and scientific field management. Its working performance directly affects the quality of fertilizer spreading, which is related to the distribution accuracy of fertilizer in the row and depth, and will affect the quality and yield of tea leaves. [0003] Mechanized fertilization can significantly improve efficiency and reduce labor intensity, but at present there is a lack of special fertilization equipment in tea gardens. As a traditional fertilization method, manual fertilization is labor-intensive and the efficiency of manual work is low, ...
