Description
Technical Field
The invention relates to the technical field of agricultural mechanical equipment, in particular to a combine harvester capable of crushing or retaining straws.
Background
At present, the state advocates that the straws of grains are returned to the field after being harvested, then the deep ploughing is carried out to the soil and the field is fertilized, the straws are strictly forbidden to be burnt, meanwhile, the straws are cut up and collected or returned to the field or not crushed and laid, and therefore when the straws are harvested, the ear parts of the grains need to be harvested, and the straw parts of the grains need to be harvested. Cutting devices of existing harvesters are all composed of single-layer headers, ear parts and straw parts of grains are harvested together, the cut grains, straws and ears are fed into the harvesters together, threshing is completed, and the straws are discharged. The disadvantages of the threshing machine are that the cut straws are longer, the feeding amount is large, the threshing effect is influenced, the machine breakage is large, the energy consumption is high, and the efficiency is low; meanwhile, a part of grains are mixed into the straws to be carried out, so that the grain loss is large; in addition, longer straws are not easy to be decomposed into base fertilizer after being returned to the field.
The applicant has studied the above problems, and as an inventor, previously designed a harvester (CN206791005U) with straw crushing function, which includes a header for harvesting the ears of grain, a straw crushing roller cutter for crushing the grain straw, a support frame hinged on a movable vehicle body, a driving wheel, and a transmission mechanism for transmitting power from the driving wheel to the straw crushing roller cutter, and which can crush the straw while realizing harvesting.
Although the harvester can realize the functions of harvesting and crushing, not all big grain farmers want to crush and scatter the wheat straws in the ground, and for high-quality wheat straws, the big grain farmers want the wheat straws harvested by the harvester to be reserved so as to be bundled and sold to big cattle farmers, so that part of income is increased. The aforementioned disadvantages are nevertheless present if harvesting is carried out directly using prior art single header harvesters: the cut straws are longer, the feeding amount is large, the threshing effect is influenced, the breakage of the machine is large, the energy consumption is high, and the efficiency is low.
