No-tillage seeder front and rear synchronous steering active opposite and attitude adjustment device

Abstract

The invention relates to a front and rear synchronous steering active opposite and attitude adjustment device for a no-tillage seeder, which includes a lateral movement device installed between the tractor and the no-tillage seeder and a profiling steering device installed at the rear end of the no-tillage seeder; The moving device includes a fixed frame, a traversing frame, an upper traversing optical axis, a lower traversing optical axis, an upper traversing hydraulic cylinder, a lower traversing hydraulic cylinder, a traversing angle sensor, a traversing navigation device, a control system and gravity stubble cutting The device; the profiling steering device includes a jaw-type fixed frame, a horizontal support rod, a horizontal beam, a disc deflection profiling mobile device and a steering navigation device; the disc deflection profiling mobile device includes a four-bar profiling device and a steering device. The invention enables the no-tillage seeder to have independent lateral movement capability, solves the problem of too large lateral movement resistance caused by the soil-entry parts of the no-tillage planter and the problem of sowing quality degradation caused by the front or rear lateral movement of the agricultural machine tool alone, and realizes the machine tools. Instantaneous and fast response when adjusting the working attitude.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a no-tillage seeder front and rear synchronous steering active opposite and attitude adjustment device. Background technique [0002] No-tillage sowing is one of the core techniques for implementing conservation tillage in wheat-moon cropping areas in North China. It is mainly used to sow without disturbing the topsoil and covered with crop stalks, which can effectively reduce soil wind erosion and water erosion, and improve soil physical and chemical properties. Increase soil fertility. However, after the corn is harvested, the root stubble remains, and the stubble is thick, and the surface has a large amount of straw coverage and strong toughness. When the no-tillage seeding machine sows wheat between the rows of corn stubble, there are factors such as terrain, straw distribution, and the amount of straw returning to the field. Lateral and yaw angle deviations, a...

Problems solved by technology

[0004] In view of the above-mentioned technical problems, the object of the present invention is to provide a no-tillage planter that uses satellite navigation and path planning technology to synchronously turn to the front and back, actively opposite rows and its attitude adjustment device, so as to realize the no-tillage planter sowing in opposite rows, and at the same time, it can break the stubble , stubble avoidance, anti-blocking and deviation correction, so that the no-tillage planter has the ability to move laterally independently, and it can also solve the problem of excessive lateral movement resistance caused by the soil-entry parts of the no-tillage planter and simply relying on the front or rear of the agricultural machine. To solve the problem of sowing quality degradation, realize the instantaneous and rapid response when the attitude of the equipment is adjusted, improve the quality of the operation of the equipment, and effectively improve the speed and reliability of the field operation
