Active Navigation Steering Levelling Universal Suspension for No-Till Planters

Abstract

The invention relates to an active-navigation steering-leveling type universal hanging device for a no-tillage planter. The hanging device is used for hooking a tractor with the no-tillage planter. The hanging device comprises a transverse-movement fixed frame, a transverse-movement movable frame and a control system, wherein the control system comprises a satellite and inertia aided navigator anda control module; the control module controls the tractor to realize course adjustment so as to correct course deviation according to the course deviation, transverse deviation and height differenceinformation transmitted by the satellite and inertia aided navigator; the control module controls a left transverse adjusting hydraulic cylinder and a right transverse adjusting hydraulic cylinder, ora left ball screw or a right ball screw to work to transversely move the transverse-movement movable frame leftwards and rightwards, so as to correct the transverse deviation of the no-tillage planter; and the control module controls stretching and retracting of an upper hanging hydraulic cylinder, a left height adjusting hydraulic cylinder and a right height adjusting hydraulic cylinder, adjuststhe heights of three hanging points of the no-tillage planter and compensates height difference caused due to surface relief. By virtue of the hanging device, the tractor and the no-tillage planter are in independent motion states, row-following stubble avoiding and anti-blocking operations of the no-tillage planter are realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to an active navigation steering and leveling universal suspension device of a no-tillage seeder. Background technique [0002] No-till and low-tillage seeder implements seeding operations on the surface of no-tillage or low-tillage. There is often a certain degree of straw residue coverage on the surface, and the amount of straw residue coverage affects the reliability of the no-tillage seeder operation. In the wheat and corn double-cropping areas of North China, the ditch openers are easy to block and the sowing quality is poor when no-tillage wheat is planted after corn stubble is harvested, which has become a key technology that restricts the implementation of the whole-process mechanized conservation tillage system in the double-cropping areas of North China. difficulty. During the actual no-tillage sowing operation, there are problems such as the opener is easy to...

AI Technical Summary

Problems solved by technology

During the no-tillage sowing of wheat between corn stubbles, it is necessary to sow accurately in rows to avoid the problem of openers colliding with corn stubbles due to lateral errors. Since the navigation tractor is likely to cause lateral deviations of the no-tillage planters, compensation is required. Lateral movement is required; in order to compensate for the change in pitch angle caused by terrain undulations, the terrain is profiled, but the current suspended no-tillage planter cannot effectively compensate for the change in pitch angle caused by terrain undulations in real time; the lateral movement caused by large slope changes The change of the roll angle, the suspended no-tillage planter can not effectively compensate for the change of the terrain; due to the lateral angle deviation of the tractor, it is necessary to correct the lateral angle of the no-tillage planter, and it is necessary to adjust the forward angle of the no-tillage independent correction
