Intelligent precision corn drilling sowing single body

Abstract

The invention relates to an intelligent precision corn drilling sowing single body, which belongs to the field of agricultural machinery. The intelligent precision corn drilling sowing single body comprises a mechanical part and a monitoring control part; a human-computer interaction module sends preset planting distance and preset sowing depth to a microprocessing controller through a CAN (Controller Area Network) bus module; the microprocessing controller controls the revolving speed of a direct current brushless motor and the elongation amount of an electric push rod according to the preset sowing length and planting distance, the value of a speed sensor, a speed value collected by a navigation module and the value of a pressure sensor through the direct current brushless motor and an electric push rod pushing module so as to realize the accurate control over the planting distance and the real-time control over the sowing depth; the microprocessing controller sends the real-time working condition of a sowing single body to the human-computer interaction module through the CAN bus module. By use of the intelligent precision corn drilling sowing single body, the accurate control over the planting distance and the real-time control over the sowing depth can be directly and effectively realized, sowing quality and working efficiency are improved, and sowing cost and labor intensity are lowered.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to an intelligent corn sowing unit, which is mainly used in agricultural sowing engineering. Background technique [0002] As one of the key links in the agricultural production process, sowing is directly related to the stable and increased yield of crops. Intelligent precision seeding technology can not only save high-quality seeds, reduce the workload of field thinning, and reduce the labor intensity of farmers, but also ensure accurate sowing amount, consistent sowing depth, and uniform plant spacing, so that the allocation of acres of plants in the field is reasonable, and the land and resources are effectively used. Sunshine resources, so as to ensure that the seedlings are complete, complete and strong, so as to achieve stable and high yields of crops and increase farmers' income. However, in the actual operation process of precision seeding single unit, the...

Problems solved by technology

The use of precision seed metering device can greatly improve the precision seeding, but the power of the ground wheel is still used as the power source of the seed metering device. Due to the limitation of the mechanical structure, several specific types can only be realized by changing the transmission ratio. The plant-to-plant distance cannot be infinitely adjusted. At the same time, due to the inevitable slippage of the ground wheels, the problem of precise control of the plant-to-plant distance cannot be fundamentally solved.

In order to achieve consistent sowing depth, the mechanical sowing unit basically adopts a four-link profiling structure, but there are uncontrollable factors in the four-link profiling structure, which cannot fundamentally solve the real-time control of sowing depth
