Problems solved by technology

When working in the field, the ups and downs of the ground will cause the table to bounce erratically, so that the table sometimes leaves the ground, and sometimes "shovels" due to untimely self-adaptive movement. If it bounces during harvesting or recycling operations, it will cause missing harvest or Recycling, while shoveling increases trash content for harvesting or recycling operations
Existing agricultural machinery mainly uses springs to passively improve the self-adaptive effect of the workbench. Since the rigidity of the spring is constant, and the operating conditions of agricultural machinery vary widely, a certain amount of self-adaptive motion can indeed be improved through simple springs. However, under different working conditions, the operation effect of agricultural machinery varies greatly.

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings.

[0049] as attached figure 1 As shown, in the present invention, the workbench system of agricultural machinery includes a workbench 1 and a frame 4, wherein the frame 4 is fixed on a mobile host, which can be a tractor or a specially designed mobile platform. The rear end of the workbench 1 is hinged on the frame 4 , and the front end of the workbench 1 is provided with support wheels 2 ; in addition, an elastic device 3 is connected between the workbench 1 and the frame 4 , and the elastic device 3 includes a spring 31 .

[0050] Based on the above structure, the adaptive control system of the agricultural machinery workbench of the present invention includes a controller 8, a speed detection element 5 and a damper 32; the damper 32 belongs to the elastic device 3, and it is arranged in parallel with the spring 31 ; The damper 32 is a magnetorheological damper; as at...

Abstract

The invention discloses a self-adaptive regulation and control method and control system for an agricultural machine workbench. The method comprises the steps of obtaining a contrast relationship between an operation speed and a damping coefficient; acquiring the current running speed of the agricultural machine; judging whether the running speed is matched with the damping coefficient of the damper or not according to the contrast relation to obtain a first judgment result; when the first judgment result is yes, maintaining the damping coefficient constant, and when the first judgment result is no, regulating the damping coefficient to be matched with the running speed, so that the response amplitude of the system is reduced, and specifically, when the running speed is too high, lowering the damping coefficient, and when the running speed is small, increasing the damping coefficient. The elastic device with the damper is arranged between the moving main machine and the rack of the workbench, the operation speed of the agricultural machine is monitored, and the damping coefficient of the damper is adjusted in real time according to the operation speed, so that the workbench can have good self-adaptive vibration reduction operation capacity.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery control systems, in particular to an adaptive control method and control system for an agricultural machinery workbench. Background technique [0002] At present, agricultural machinery is very popular, and all aspects of agricultural production can generally be completed by agricultural machinery. Agricultural machinery generally includes mobile hosts and workbenches. The mobile host is mainly controlled by humans to move in the field, and the workbench is the part that acts on crops. , according to actual needs, the workbench can be set as a harvesting workbench, sowing workbench, recycling workbench, etc. In some agricultural production links, the relative position between the workbench and the ground is relatively high, because the ground is generally undulating, Therefore, an adaptive device needs to be provided to make the workbench undulate with the undulation of the ground. ...
