Continuously variable transmission type variable fertilizer applicator

Abstract

The invention relates to fertilizing machinery, in particular to a continuously variable transmission type variable fertilizer applicator. The fertilizer applicator mainly comprises five parts, namelya rack, a fertilizing mechanism, a variable speed transmission mechanism, a soil covering mechanism and a ditching mechanism. The rack comprises a motor mounting table, a speed changer mounting table, a fertilizing mechanism mounting frame, a soil covering mechanism mounting frame and a ditching mechanism mounting frame; the fertilizing mechanism mainly comprises a fertilizer discharging auger, afertilizer hopper and a fertilizer discharging pipe; the variable speed transmission mechanism mainly comprises a stepping motor and a gearbox, and the soil covering mechanism mainly comprises a soilcovering disc and a secondary adjusting rod; and the ditching mechanism mainly comprises a ditching cutter head and a ditching cutter. According to the fertilizer applicator, a single chip microcomputer and a GPS control the speed change of the stepping motor in real time, the change of the fertilizing amount is controlled in real time, the ditching mechanism ditches and fertilizes, then the soilcovering mechanism fills and levels up ditches, and all the parts are matched with one another to achieve the variable fertilizer discharging process.

Description

technical field [0001] The invention relates to the field of fertilizing machinery and equipment, in particular to a continuously variable transmission type variable fertilizing machine. Background technique [0002] For variable fertilization, we need to make reasonable use of chemical fertilizers, and the study of fertilization technology has very profound significance for the development of agriculture in our country. my country is a large agricultural country, and it is very necessary to implement variable fertilization. It can improve the utilization rate of fertilizers, improve the adverse effects of fertilizers on the environment, and make the economy and ecological environment develop in a high-quality direction. Due to the limited range of fertilizer adjustment, inconvenient operation, and less research on mechanical CVTs in my country's variable fertilization technology, a variable variable fertilizer with a CVT is proposed. The structure of the fertilizer applic...

Problems solved by technology

[0003] The purpose of the present invention is to provide a continuously variable transmission type variable fertilizer applicator to solve the problem of limited range of adjustment of seed fertilizers, inconvenient operation and relatively poor research on mechanical continuously variable transmissions in the existing variable fertilization equipment proposed in the above technical background. In order to solve the problem, a cam-link mechanism is designed to be applied to a continuously variable transmission, and a cam-link continuously variable transmission is designed. The structure of the transmission is simple and compact, and the amount of fertilizer application can be adjusted without stopping the fertilizer applicator, which is easy to operate. , greatly improve the working efficiency of the fertilizer applicator, increase the utilization rate of chemical fertilizers, improve the farmland environment, increase the yield of crops, and increase the income of crops
