Precision seeder for corn breeding test

Abstract

The invention relates to a precision seeder for a corn breeding test. The precision seeder comprises a main rack, an operation platform, a fertilizing device, a pneumatic device, fertilizing furrow openers, a boundary detection device, seeding units, a seed cleaning box, a pesticide applying device and land wheel transmission devices; a three-point suspension mechanism is arranged at a front end of the main rack, the pneumatic device is connected to the front end of the main rack, the fertilizing device is connected to the main rack behind the pneumatic device, the operation platform is connected to a rear of the fertilizing device, the two seeding units are connected to the main rack, and the pesticide applying device is connected to upper parts of the seeding units; and the land wheel transmission devices are connected to positions, located on outer sides of the seeding units, of two sides of the main rack respectively, and the boundary detection device is fixedly connected to a front portion of a left side of the main rack. Starting from optimization of structures of a seed dividing device, the fertilizing device, a seed metering device and a suction power system, a reasonable structural design meets requirements of uniform seeding and stable fertilizer and pesticide application during precision seeding in a corn breeding test.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a precision seeder used for corn breeding experiments. Background technique [0002] The mechanization level of existing breeding field experiments in our country is relatively low, and most of them need to carry out breeding operations manually, because in the process of breeding field experiments, there are many experimenters, the experimental conditions are difficult to control, and the sowing forms and methods are various and error-prone. This reduces the accuracy and efficiency of corn breeding field experiments, and affects the authenticity and scientificity of the results of corn breeding experiments. With the rapid development of my country's breeding industry, the requirements for field trials of corn breeding are also constantly increasing. How to realize efficient and accurate mechanized sowing operations for corn breeding is a major problem faced by all scientifi...
