AI Technical Summary

Benefits of technology

In this new technology, there are several benefits that make them more efficient than older methods like manual or mechanical plantings. These improvements include improved precision and consistency during operation due to their enclosed loop design, ability to regulate both seed spacing and nutrients delivery based upon specific conditions, ease of use when changing soil types without having to modify equipment, versatility across various fields (such as rice) while maintaining good performance over longer periods of time.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency at producing cropped products such as oils from plants like corn or wheat without increasing their cost burden on farmers who have limited resources. Current mechanical systems used for growing these crops require multiple steps that can make them slow down while they produce heavy residue left over after being collected. Therefore, new ways to improve the process would help reduce costs associated with collecting and utilizing excessive amounts of land needed per unit volume.

Abstract

The invention discloses an automatic control system for variable seeding and fertilization and a multifunctional planter. The multifunctional planter comprises a power system, a rack, a rotary-plowing and ditching system, a sowing system and a fertilizing system. The control system comprises ground wheels, a rotary code disc, a servo motor, a server and a single-chip microcomputer. A program of a function formula f (Q) = (n, v) of the sowing quantity (Q) of the planter versus the rotation speed n of the seeding axle and the forward speed v of the planter is written into the single-chip microcomputer. The ground wheels rows in drainage ditches so as to advance synchronously with the whole machine; the forward speed v of the ground wheels is measured in real time by using the rotary code disc; a pulse signal is sent to the single-chip microcomputer; the single-chip microcomputer calculates the rotation speed of the seeding axle according to the sowing quantity and the forward speed of the planter, and transmits a signal to the server; the server controls the output rotation speed of the direct-current servo motor by transmitting a pulse signal; and the servo motor directly drives rotation of the seeding axle. According to the invention, the overall structure is reasonable. The whole system forms a closed-loop control system and can meet the requirements of accurate and variable seeding and fertilization.
