An electric-driven small area corn precision metering device and its working method

Abstract

The invention belongs to the field of automatic agricultural equipment, and in particular relates to an electric-driving type plot corn precision seeding device and a working method thereof. The electric-driving type plot corn precision seeding device comprises a seed feeding module, a gas plugging module, a seed unloading module, a seed discharging module and a photoelectric detection module. The seed feeding module, the gas plugging module and the seed unloading module are coordinated and orderly act according to a set program, so that the seeding device is capable of guaranteeing excellent seed charging performance, seed cleaning performance, seed discharging performance and seed changing performance in a proper working pressure range and a rated discharge plate rotational speed range. Furthermore, the air-aspiration type plot corn precision seeding device has good seed charging performance under the condition that the number of seeds in a seed charging plot is less, and the requirements on fast seed changing among plots and no mixing of seeds in different plots are met.

Description

technical field [0001] The invention belongs to the field of automatic agricultural equipment, and in particular relates to an electric drive type small area corn precision metering device and a working method thereof. Background technique [0002] At present, there are two types of planting machinery in my country's plots: mechanical and pneumatic. The widely used mechanical precision metering devices include spoon wheel type, finger clip type, socket wheel type, inner seed filling type, belt type, Horizontal type and inclined disc type, etc. [0003] The basic working principle of the mechanical seed meter is similar. They are designed according to the shape and size of the seeds, such as corresponding holes or grooves to accommodate the seeds, and then remove the excess seeds through the cleaning process of gravity or mechanical structure to achieve A function to isolate the desired seed. It has the advantages of simple overall structure, low cost, and good low-speed ope...

Problems solved by technology

However, due to the need for additional fans and pressure adjustment equipment, the structure is complex and the production cost is increased.

[0006] At present, pneumatic plot precision seeders are widely used for sowing in plots. The significant difference between plots and field sowing operations lies in the characteristics of "more parts and less quantity". In addition to the quality of the sowing, it is necessary to sow a small amount of seeds within a short length of a plot and ensure that each plot does not mix the seeds, and the seeds can be replaced quickly in intervals.
