Description
Technical Field
The invention relates to the field of pasture harvesting machinery, in particular to an operation posture adjusting device of a header for harvesting alfalfa.
Background
The development of animal husbandry has not opened up the increase in the production and supply levels of forage. At present, the alfalfa harvesting mechanization level in China is low, and compared with similar machines in developed countries, the alfalfa harvesting mechanization level has the problems of low automation, digitalization, mechanical-electrical-hydraulic integration degree, unstable technical performance, poor reliability and the like. The intelligent development of the alfalfa harvesting mechanization technology and equipment is further accelerated, and the method has important significance for realizing the balanced supply of high-quality forage grass and promoting the sustainable development of grassland animal husbandry.
The harvesting process of the alfalfa comprises the working links of cutting, flattening, strip collecting and the like. Wherein the alfalfa cutting height in the cutting process can greatly influence the quality of the alfalfa which grows subsequently, and the uniform and consistent cutting height can ensure that the alfalfa which grows subsequently has better quality [4 ]. The uniformity of the alfalfa stubble can be ensured by adjusting the parallelism and height of the header to the ground in the operation process. At present, related alfalfa harvesting machines in China mostly ensure the alfalfa stubble height in a mode of adjusting and fixing the cutting table before operation, but the cutting table cannot have the capability of profiling along with the ground and automatically adjusting the operation posture through the operation, and the cutting table still fluctuates along with the ground in the harvesting operation process, so that the problem of uneven stubble height is caused. Small narrow-width alfalfa harvesters are also relatively less affected by this, but the impact is somewhat severe for large alfalfa harvesters where the swaths are wider. Taking the header width 5m as an example, when the header and the ground have an included angle of 1 degree, the alfalfa cutting height difference at the left and right side end points of the header can reach 87 mm. If the stubble cutting reference height is positioned at the center of the header, the stubble cutting height at the two ends deviates from the set height by about 43 mm.
In order to solve the problems, the header can automatically adjust the operation posture under the condition that the operation machine runs on the fluctuated ground, keeps parallel to the ground at any time, and keeps the height of the header to the ground at a set height all the time through continuous adjustment, and the header operation posture adjusting device for the alfalfa harvesting is designed.
