Sugarcane planter planting density speed-dependent synchronous control system

Abstract

The invention relates to a sugarcane planter planting density speed-dependent synchronous control system which comprises a hydraulic driving system and an electrical control system, the hydraulic driving system comprises a proportional control valve and a driving motor, the driving motor is used for driving a sugarcane seed conveying device of a sugarcane planter, and the proportional control valve is connected to a bypass of the driving motor; the proportional control valve is an electric control proportional control valve; the electrical control system comprises a proportional valve driver,a DA module, a programmable controller, a walking speed measuring device, a driving motor speed measuring sensor and a human-computer interface. The walking speed measuring device comprises an inductive proximity sensor installed on the tractor and a plurality of protruding metal strips installed on a walking transmission shaft of the tractor. The system has the beneficial effects that synchronouschange of the conveying speed of the seed feeding mechanism of the sugarcane planter and the walking speed of the tractor for pulling the planter can be achieved, sugarcane planting density uniformity is guaranteed, and sugarcane planting operation mechanization can be promoted.

Description

technical field [0001] The invention relates to the field of automatic control of agricultural engineering, in particular to a planting density synchronous control system for sugarcane planters. Background technique [0002] The seed metering device of the pre-cut sugarcane planter pulled and driven by a tractor is usually a continuous motion seed delivery mechanism, which can continuously send the sugarcane seed buds (segments) in the sugarcane seed box and throw them into the next In the seeding trough, it falls into the planting ditch under the guidance of the lower seeding trough, and completes the sugarcane planting operation with other processes such as fertilization, soil covering, and film covering. Since the walking speed of the tractor pulling the planter in the sugarcane planting field varies with different working conditions and gears, and the seed delivery mechanism is usually driven by the power output shaft or hydraulic pressure of the tractor, the movement sp...

AI Technical Summary

Problems solved by technology

Since the walking speed of the tractor pulling the planter in the sugarcane planting field varies with different working conditions and gears, and the seed delivery mechanism is usually driven by the power output shaft or hydraulic pressure of the tractor, the movement speed of the seed delivery mechanism is the same as that of the traction planter. The walking speed of the tractor cannot be synchronized, or manual operation is required to change the feeding speed, which cannot guarantee that the feeding speed can be synchronized with the change of the tractor speed, resulting in low planting density when the tractor speed is fast, and high planting density when the walking speed is slow
