Problems solved by technology

[0004] If you want to avoid obstacles with a large size, you need to increase the pressure of the hydraulic accumulator. However, when the pressure of the hydraulic accumulator is adjusted too high, the copying ability of the header is increased, and the header is easy to Copying rises, but after the rise, due to the change of the support moment of the header cylinder, the support force of the header and the cylinder forms a balance in the new position, so that the header will not be lowered to the working height again, thus affecting the use of the header

[0049] Please refer to figure 1 , the present embodiment provides a method for controlling a header profiling system, including:

[0050] Start the automatic control unit;

[0051] During the movement of the header, the header floats up and down under the action of the hydraulic accumulator;

[0052] Detect header height;

[0053] When the height of the header rises to the trigger height, the lifting drive mechanism starts, and the lifting drive mechanism drives the header to rise to the termination height;

[0054] After the delay setting time T1, the lifting drive mechanism drives the header down to the working height;

[0055] The working height is less than the trigger height.

[0056] The header profiling system and its control method are applied to the combine harvester. During use, the header is at the working height, and the header moves with the movement of the combine harvester. Under the action of the hydraulic accumulator, it automatically moves upwards to avo...

[0087] Such as figure 2 - Figure 6As shown, this embodiment provides a header 1 profiling system, which applies the control method of the header 1 profiling system provided by the first embodiment above. The header 1 profiling system includes the header 1 and an automatic control unit. The automatic control unit includes a lifting drive mechanism, a hydraulic accumulator 3, an automatic control mechanism, and a sensing mechanism. The header 1 is connected to the lifting drive mechanism, and the lifting drive mechanism is connected to The hydraulic accumulator 3 is connected, and the sensing mechanism is used to detect the height of the header 1; the automatic control mechanism is respectively connected with the lifting drive mechanism and the sensing mechanism, and the automatic control mechanism is used for the effect of the hydraulic accumulator 3 on the header 1. When ascending to the trigger height, the header 1 is moved up to the termination height through the lifting ...

Abstract

The invention discloses a profiling system of a cutting table and a control method of the system, and relates to the technical field of agricultural machinery. The control method of the profiling system for the cutting table comprises the steps that an automatic control unit is started; in a moving process of the cutting table, the cutting table floats up and down under the action of a hydraulic energy accumulator; the height of the cutting table is detected; when the height of the cutting table is increased to the trigger height, a lifting driving mechanism is started, and the lifting drivingmechanism drives the cutting platform to ascend to the termination height; and after a set time T1 is delayed, the lifting driving mechanism drives the cutting table to descend to the working height,wherein the working height is lower than the trigger height. The cutting table profiling system uses the control method. According to the profiling system of the cutting table and the control methodof the system, an automatic lifting mechanism assists the hydraulic energy accumulator control in controlling the cutting table to ascend and descend, so that the profiling capability of the cutting table is better and the cutting table still can return to the working height after avoiding a relatively large barrier.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a header profiling system and a control method thereof. Background technique [0002] When the harvester, especially the low stubble harvester, encounters an obstacle, the header profiling system will control the header to move away from the obstacle, so as to avoid the harvester from being stuck at the obstacle due to the header Unable to continue moving. [0003] At present, there is a header profiling system that uses the hydraulic energy storage device and the switch valve of the accumulator to make the hydraulic energy of the hydraulic accumulator act on the lifting cylinder of the header during operation, so that when the header encounters obstacles during the work It can automatically profile and raise a certain distance, so as to avoid the undulating ground of the field. [0004] If you want to avoid obstacles with a large size, you need to increase the pressure of...
