Cutting and walking servo-actuated regulating system of combined harvester

Abstract

The invention relates to a cutting and walking servo-actuated regulating system of a combined harvester. The system comprises dual vertical cutter transmission devices, a main cutter transmission device, a reel and spiral delivery auger transmission device, and a speed measurement and servo-actuated regulating system. The speed measurement and servo-actuated regulating system can constantly measure the real-time forward speed of a machine through a speed measuring radar, constantly adjust the rotating speeds of a first direct current motor, a second direct current motor, a third direct current motor and a hydraulic motor in the left vertical cutter transmission device, the right vertical cutter transmission device, the main cutter transmission device and the reel and spiral delivery auger transmission device, so that the components rotate at the corresponding rotating speed so that the cutting track of cutters of the combined harvester at various forward speeds, the elastic tooth track in a reel and a spiral auger can meet the good cutting performance, the good reeling performance and the good conveying performance, it is ensured that a header does not perform repeated cutting and missed cutting, crops are not stacked in the header, crop impact is small, and the system has the wide application range.

Description

technical field [0001] The invention relates to a cutting and walking follow-up adjustment system of a combine harvester, which belongs to the technical field of combine harvesters. Background technique [0002] At present, most combine harvesters on the market use the way of inputting power from the traveling system and the header cutting system respectively. The power transmission between the two is not related, and they work independently. However, the cutting trajectory of the cutter and the guidance and support trajectory of the reel are closely related to the forward speed of the machine. Only when the cutting frequency of the cutter and the rotational speed of the reel match the forward speed of the machine, can the header achieve smooth operation of the crops. Supporting and cutting, no heavy cutting and missing cutting; at the same time, due to the different cutting frequencies required by different crops (rice, wheat, rapeseed), the impact speed and number of times...

AI Technical Summary

Problems solved by technology

[0005] When the combine harvester is working in the field, the cutting frequency of the cutter on the header, the speed of the reel and the screw auger cannot match the forward speed of the machine, which will easily lead to heavy cutting and missing cutting during harvesting, and the crops will be damaged when reeling. Accumulation, too much impact on the head of the ear, etc.
