Front-back synchronous steering active row control and posture adjustment device of no-tillage planter

Abstract

The invention relates to a front-back synchronous steering active row control and posture adjustment device of a no-tillage planter. The front-back synchronous steering active row control and postureadjustment device comprises a transverse moving device installed between a tractor and the no-tillage planter and a profiling steering device installed at the rear end of the no-tillage planter. The transverse moving device comprises a fixed frame, a transverse moving frame, an upper transverse moving polished shaft, a lower transverse moving polished shaft, an upper transverse moving hydraulic cylinder, a lower transverse moving hydraulic cylinder, a transverse moving angle sensor, a transverse moving navigation device, a control system and a gravity stubble cutting device. The profiling steering device comprises jaw type fixed frames, horizontal supporting rods, a horizontal cross beam, disc deflection profiling moving devices and a steering navigation device. The disc deflection profiling moving devices comprise four-rod profiling devices and steering devices. By means of the device, the no-tillage planter has independent transverse moving capacity, the problems that transverse moving resistance is too large due to the fact that the no-tillage planter is provided with a soil penetrating component, and the seeding quality is reduced due to the fact that the no-tillage planter only depends on transverse moving of the front portion or the rear portion of an agricultural implement are solved, and the instantaneous quick response is achieved when the implement conducts row control work and posture adjustment.

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
